10 INTRODUCTION

Nomiandeau Associates (Nomiandeau) was contracted by Weston Solutions Inc (WESTON) to complete a review of an approximate 2-mile stretch of an winamed stream approximately 50-foot stretch of three tributary streams (Tributaries 12 and 3) and all associated bordering wetlands for the Commerce Street Plume Project in Williston Vermont The length of each class of wetiands bordering either bank of the stream was measured The unnamed stream and beginning portions of its three tributary streams were to be assessed for potential habitat for two Vermont listed threatened species eastem sand darter Ammocrypta pellucida) and eastem pearlshell mussel Margaritifera margaritifera) The results of the review will be used by the EPA in drafting a Hazard Ranking System package for potential listing of the Commerce Street Plume site on the National Priorities List

20 METHODOLOGY

Normandeau completed the site investigation on June 21 and 22 2004 WESTON personnel showed Normandeau the limits of the investigation access points and locations of sediment sampUng stations along the stream corridor prior to the start of the investigation The stretch of unnamed stream included in the review began approximately 750 feet north of Route 2 (Williston Road) and extended south between Harvest Lane on the east Commerce Street on the west It crossed Marshall Avenue and ended approximately 1100 feet south of the road (Figure 1) Two tributaries (Tributary 2 and Tributary 3) were also reviewed in the immediate area of where they entered the unnamed stream The confluence of Tributary 2 is located just south of Marshall Avenue The Tributary 3 confluence is approximately midway between Marshall Avenue to the south and Route 2 to the north The confluence of a third tributary (Tributary 1) is located near the Interstate 89 crossing of South Brownell Road During field activities Tributary 1 was considered outside the study area by WESTON

Wetlands

Normandeau identified wetlands bordering the unnamed stream according to the US Fish and Wildlife Service wetland classification system (Cowardin et al 1979) The wetiand class was also determined at the confluence of two tributaries with the unnamed stream Wetland identification was based on vegetation observations of indicators of hydrology and soil borings to confirm the presence of hydric soils Observations were recorded documenting wetland characteristics (Appendix A)

The start and end points of the dominant wetland class were located using a Trimblereg Global Positioning System (GPS) unit In most cases the wetland class was the same on both sides of the stream In those instances where the class differed Nomiandeau located the start and end point of the wetland class on both sides of the stream The linear length of wetland on each side of the stream was then calculated by wetland class along segments identified by WESTON

Threatened Species Habitat Assessment

A habitat assessment was conducted of the unnamed stream to identify potential suitable habitat for the Eastem Pearlshell (Margaritifera margaritifera) and the Eastem Sand Darter Ammocrypta pellucida) Both species are listed as threatened in the State of Vermont In order to minimize disturbance of the streambed substrate during observations the habitat assessment began at the downstream (southern) end of the unnamed stream corridor off South Brownell Road and continued upstream to approximately 750 feet north of Route 2 Where possible observations were made while walking in the streambed to best determine substrate type and depth Otherwise observations were made streamside A metal soil auger was used to probe the substrate to help determine sediment type and depth Notes were also made on flow rate water depth width of stream channel height of banks vegetation cover and suitability for the species of concem Habitat descriptions were recorded on field data sheets (Appendix B) For description purposes the stream was divided into segments corresponding with stream corridor GPS points and wetland identifications

GPS Location and Mapping

Normandeau located the start and end points of the wetlands and potential habitat for the eastern pearlshell and sand darter using a Trimblereg GPS luiit The GPS data were post processed to provide submeter accuracy A summary of the post processing data with a horizontal precision of 95 is provided in Appendix C Reference points were located for use in insertion onto the base map The base map was compiled using available information from the Vermont Center for Geographic Information sediment sampling stations provided by WESTON and Vermont Significant Wetland Inventory map data

30 FINDINGS

Wetlands

The wetlands bordering the unnamed stream corridor are in the Palustrine (fieshwater) system and the stream and wetlands within the channel are within the Riverine system The dominant wetland classes bordering the stream are Palustrine Emergent persistent (PEMl) and Palustrine Scmb Shrub broad-leaved deciduous (PSSl) with Palustrine Forested deciduous (PFOl) wetlands observed along the uplandwetland edge (Figures 2 3 and 4) The majority of the stream channel is classified as Riverine Lower Perennial Unconsolidated Shore sandmud (R2US23) A total of 6697 linear feet of stream channel was reviewed and 12047 feet of wetiand classified along the banks of the unnamed stream (Table 1)

Along the project corridor the wetlands bordering the unnamed stream are within the 100-year floodplain The wetland system is dynamic within the stream corridor as a result of fluctuating water levels related to a series of beaver dams several of which are shown on mapping compiled by WESTON (Appendix C) At the time of the field investigation all the dams had been breached allowing water levels to drop The upstream wetlands in the immediate area of the dams are currentiy dominated by emergent vegetation which would be expected to change to a mix of shrubs and emergent species if water levels are maintained at current levels

North of Route 2 the stream channel has been piped under an existing facility (Lot 8-105-22) The emergentshrub swamp north of the facility is approximately 300 feet wide Downstream of Route 2 the stream corridor has been impacted by development particularly fi-om Route 2 south to a point approximately 500 feet south of SDSW 18 (Lot 7-19-36) The stream channel has been ditched and the bordering wetlands range fiom 5 to 15 feet in width with the exception of an area aroimd a former beaver dam intiie vicinity of SDSW 30 (Lot 7-19-20)

Beginning at the confluence with Tributary 3 and extending downstream there have been fewer impacts to wetiands and the unnamed stream except at road crossings and along sections of the westem bank bordering the Commerce Street industrial park The stream channel is sinuous with well defined banks The bordering wetlands range from 20 to 200 feet in width and are primarily shrub swamp with emergent species in the understory and trees along the wetland edge There is a short segment of forested wetland downstream of Marshall Avenue The trees near the road and extending up Tributary 2 to a road crossing to a commercial development (the road and development were constructed after the date of the aerial photography (Figure 4)) have died back as a result of flooding due to a beaver dam which has since been breached

The dominant herbaceous species within the emergent wetiands along the uimamed stream include reed canary grass Phalaris arundinacea) jewelweed Impatiens capensis) purple loosestrife Lythrum salicaria) goldeiuod species Solidago spp) red top Agrostis alba) wool grass Scirpus cyperinus) shallow sedge Carex lurida) sedge species Carex spp) sensitive fem Onoclea sensibilis) soft msh Juncus effusus) and broad-leaved cattail Typha latifolia) The dominant shmb species within the shrub swamp along the unnamed stream include alder Alnus incana) arrowwood Vibemum dentatum) grey birch Betula populifolia) elderberry Sambucus canadensis) honeysuckle Lonicera spp) and alder-buckthom Frangula alnus) The dominant tree species within the forested wetland along the unnamed stream include red maple Acer rubrum) ehn Ulmus americana) green ash Fraxinus pensylvanica)

Threatened Species Habitat Assessment

Little suitable habitat was found for either the eastern pearlshell or the eastem sand darter within the unnamed stream An approximate 1500 foot section of the unnamed stream has gravel or cobble bottom which would be considered to have low potential as habitat for the eastem sand darter This area extendsfirom just north of SD 19 to SD 35 (Figure 2) The Vermont Department of Conservation (Richard Langdon Aquatic Biologist VT DEC personal communication June 2004) concurred with Normandeaus assessment that the unnamed stream (Vermont Tributary 4 of Muddy Brook) is an unlikely place for either eastem pearlshell or the eastem sand darter to occur

Streambed characteristics were similar along the entire length of the unnamed stream with some variations in width depth and vegetative cover The unnamed stream is perennial with a narrow chaimel 2 to 5-feet wide and soft substrate bottom Flow at the time of observation was moderate (lt 1 foot per second) except behind the numerous breached beaver dams where flow is much reduced The stream charmel is generally well defined with 1 to 2 foot high banks In some areas the banks are less than 1 foot high Near the Route 2 culvert the banks were over 6 feet high Silt over fine spounduid and mud was the dominant substrate type with the exception of the sectionfi-om SD19 to SD 35 which has more gravel and cobble substrate The following species were observed within the unnamed stream fi-eshwater clam species (Sphaeriidae spp) minnow (Pimephales spp) shiner Notemigonus spp) killifish Fundulus spp) and stickleback (family Gasterosteidae) The eastem

pearlshell is a fireshwater mussel that prefers firm sand gravel or cobble in a range of flow conditions including fast-flowing mountain streams (Nedeau et al 2000) as well as quiet locations next to mshing waters where it can burrow in an upright position (Martin 1997) The eastem pearlshell also requires sahnonid species as the host for the development of the glochidia or larval stage (Nadeau et al 2000 Martin 1997) Sahnonids require cool fast flowing gravel cobble bottom streams (Richard Simmons Fisheries Biologist Normandeau Associates personal communication June 2004) which are not present in the area of study

The eastem sand darter is afi-eshwaterfish restricted to moderate size streams and large warm water rivers with clean sandy bottoms that have currents slow enough to retain sand but fast enough to prevent the deposition of silt (httpfishdnrcomelledun-fishPercidaesanddarterhtml Richard Langdon Aquatic Biologist VT DEC personal commimication June 2004) According to the Vermont Department of Environmental Conservation (VT DEC) this fish is almost always found below the Fall Line (150-foot elevation) in Vermont Littie information is available for this species but it has been reported in the Lamiolle River fom miles fi-om Lake Champlain and from the Poultaey River on the border between Vermont and New York

40 AGENCY COMMENTS

Richard Langdon VT DEC Aqxiatic Biologist provided three additional Vermont mussel species of concem andor threatened species that maybe found within the unnamed stream and tributaries the triangle floater Alasmidonta undulata) creek heelsplitter Lasmigona compressa) and squawfoot Strophitus undulatus) Based on a review of the literature the triangle floater can tolerate a variety of conditions including the still waters behind dams The squawfoot is uncommon and is generally a river species and the heelsplitter prefers small to medium sized rivers with fine sand or gravel substrate Normandeaus review of the urmamed stream did not specifically focus on these species but based on the current investigation the uimamed stream may provide suitable habitat for the triangle floater and the heelsplitter Further studies would have to be conducted to confirmdeny the presence of these species

50 REGULATORY OVERVIEW

The State of Vermont regulates wetiand impacts based on the wetland class as determined by the Vermont Wetland Rules The US Army Corps of Engineers (Corps) has jurisdiction over impacts to the wetiands and streams within the project area under Section 404 of the Clean Water Act However under Superfund permit equivalency the proposed work need only comply with criteria and regulations and not actaally be permitted (42 CFR 103 9621e-l)

The Vermont Wetland Rules classify wetiands into three categories Class One Two and Three The Vermont Water Resoiu-ces Board (WRB) determines Class One wetiands as exceptional or irreplaceable and merits the highest level of protection Class One wetiands must be designated by the WRB Class Two wetlands are presumed to serve one or more wetiand fimctions at a significant level The Vermont Significant Wetiand Inventory maps (VSWI) designate Class Two wetiands including most Palustrine wetlands and wetlands contiguous to mapped wetlanltis Class Three wetiands are not mapped on the VSWI maps and the WRB has not determined that these wetiands provide a significant wetiand function Class Three wetiands are not protected under the Vermont Wetiand Rules

The VSWI mapped two Class Two wetiands within the project area The wetiand north of Route 2 containing WESTON sediment sampling stations SD 25 26 28 29 (Figure 2) and a wetiand on Tributary 2 east of a commercial development access road crossing over the tributary (Figure 3) There are no Class One wetlands within the Town of Williston at this time (April Moulaert VT DEC Wetiands Ecologist personal communication June 2004) The remaining wetiands within the unnamed stream corridor are Class Three wetlands The VT DEC recommends a site review to confirm the classification of wetlands within a project area

The New England Division of the Corps has issued a Department of the Army General Permit for the State of Vermont which outiines an expedited permit process for activities with minimal wetland impacts Category A non-reportingminimal impact activities do not require a separate permit fi-om

the Corps for impacts under 3000 square feet (SF) provided that all restrictions and conditions of the General Permit are met and there are no impacts to special wetlands (fen bog and vernal pool) Category B screeningminimal impact activities include projects impacting over 3000 SF of wetiand An application is filed directly to the Corps for impacts from 5000 SF to 1 acre An individual permit fi-om the Corps is required for projects not meeting the General Permit standards

60 SUMMARY

Normandeau Associates conducted an assessment of wetland classes and threatened species habitat associated with an uimamed stream and portions of its two tributaries (Tributaries 2 and 3) in Williston Vermont for the Commerce Street Plume Project The unnamed stream channel was divided into 17 segments related to previously determined WESTON sediment sampling locations plus the immediate area of the two tributaries A total of 6697 linear feet of stream channel was reviewed and 12047 feet of wetland classified along both banks of the unnamed stream and portions of its two tributaries A habitat assessment was completed for two Vermont threatened species the eastem sand darter Ammocrypta pellucida) and eastem pearlshell mussel Margaritifera margaritifera) The assessment of the unnamed stream found no suitable habitat for these two Vermont threatened species

10 INTRODUCTION

Nomiandeau Associates (Nomiandeau) was contracted by Weston Solutions Inc (WESTON) to complete a review of an approximate 2-mile stretch of an winamed stream approximately 50-foot stretch of three tributary streams (Tributaries 12 and 3) and all associated bordering wetlands for the Commerce Street Plume Project in Williston Vermont The length of each class of wetiands bordering either bank of the stream was measured The unnamed stream and beginning portions of its three tributary streams were to be assessed for potential habitat for two Vermont listed threatened species eastem sand darter Ammocrypta pellucida) and eastem pearlshell mussel Margaritifera margaritifera) The results of the review will be used by the EPA in drafting a Hazard Ranking System package for potential listing of the Commerce Street Plume site on the National Priorities List

20 METHODOLOGY

Normandeau completed the site investigation on June 21 and 22 2004 WESTON personnel showed Normandeau the limits of the investigation access points and locations of sediment sampUng stations along the stream corridor prior to the start of the investigation The stretch of unnamed stream included in the review began approximately 750 feet north of Route 2 (Williston Road) and extended south between Harvest Lane on the east Commerce Street on the west It crossed Marshall Avenue and ended approximately 1100 feet south of the road (Figure 1) Two tributaries (Tributary 2 and Tributary 3) were also reviewed in the immediate area of where they entered the unnamed stream The confluence of Tributary 2 is located just south of Marshall Avenue The Tributary 3 confluence is approximately midway between Marshall Avenue to the south and Route 2 to the north The confluence of a third tributary (Tributary 1) is located near the Interstate 89 crossing of South Brownell Road During field activities Tributary 1 was considered outside the study area by WESTON

Wetlands

Normandeau identified wetlands bordering the unnamed stream according to the US Fish and Wildlife Service wetland classification system (Cowardin et al 1979) The wetiand class was also determined at the confluence of two tributaries with the unnamed stream Wetland identification was based on vegetation observations of indicators of hydrology and soil borings to confirm the presence of hydric soils Observations were recorded documenting wetland characteristics (Appendix A)

The start and end points of the dominant wetland class were located using a Trimblereg Global Positioning System (GPS) unit In most cases the wetland class was the same on both sides of the stream In those instances where the class differed Nomiandeau located the start and end point of the wetland class on both sides of the stream The linear length of wetland on each side of the stream was then calculated by wetland class along segments identified by WESTON

Threatened Species Habitat Assessment

A habitat assessment was conducted of the unnamed stream to identify potential suitable habitat for the Eastem Pearlshell (Margaritifera margaritifera) and the Eastem Sand Darter Ammocrypta pellucida) Both species are listed as threatened in the State of Vermont In order to minimize disturbance of the streambed substrate during observations the habitat assessment began at the downstream (southern) end of the unnamed stream corridor off South Brownell Road and continued upstream to approximately 750 feet north of Route 2 Where possible observations were made while walking in the streambed to best determine substrate type and depth Otherwise observations were made streamside A metal soil auger was used to probe the substrate to help determine sediment type and depth Notes were also made on flow rate water depth width of stream channel height of banks vegetation cover and suitability for the species of concem Habitat descriptions were recorded on field data sheets (Appendix B) For description purposes the stream was divided into segments corresponding with stream corridor GPS points and wetland identifications

GPS Location and Mapping

Normandeau located the start and end points of the wetlands and potential habitat for the eastern pearlshell and sand darter using a Trimblereg GPS luiit The GPS data were post processed to provide submeter accuracy A summary of the post processing data with a horizontal precision of 95 is provided in Appendix C Reference points were located for use in insertion onto the base map The base map was compiled using available information from the Vermont Center for Geographic Information sediment sampling stations provided by WESTON and Vermont Significant Wetland Inventory map data

30 FINDINGS

Wetlands

The wetlands bordering the unnamed stream corridor are in the Palustrine (fieshwater) system and the stream and wetlands within the channel are within the Riverine system The dominant wetland classes bordering the stream are Palustrine Emergent persistent (PEMl) and Palustrine Scmb Shrub broad-leaved deciduous (PSSl) with Palustrine Forested deciduous (PFOl) wetlands observed along the uplandwetland edge (Figures 2 3 and 4) The majority of the stream channel is classified as Riverine Lower Perennial Unconsolidated Shore sandmud (R2US23) A total of 6697 linear feet of stream channel was reviewed and 12047 feet of wetiand classified along the banks of the unnamed stream (Table 1)

Along the project corridor the wetlands bordering the unnamed stream are within the 100-year floodplain The wetland system is dynamic within the stream corridor as a result of fluctuating water levels related to a series of beaver dams several of which are shown on mapping compiled by WESTON (Appendix C) At the time of the field investigation all the dams had been breached allowing water levels to drop The upstream wetlands in the immediate area of the dams are currentiy dominated by emergent vegetation which would be expected to change to a mix of shrubs and emergent species if water levels are maintained at current levels

North of Route 2 the stream channel has been piped under an existing facility (Lot 8-105-22) The emergentshrub swamp north of the facility is approximately 300 feet wide Downstream of Route 2 the stream corridor has been impacted by development particularly fi-om Route 2 south to a point approximately 500 feet south of SDSW 18 (Lot 7-19-36) The stream channel has been ditched and the bordering wetlands range fiom 5 to 15 feet in width with the exception of an area aroimd a former beaver dam intiie vicinity of SDSW 30 (Lot 7-19-20)

Beginning at the confluence with Tributary 3 and extending downstream there have been fewer impacts to wetiands and the unnamed stream except at road crossings and along sections of the westem bank bordering the Commerce Street industrial park The stream channel is sinuous with well defined banks The bordering wetlands range from 20 to 200 feet in width and are primarily shrub swamp with emergent species in the understory and trees along the wetland edge There is a short segment of forested wetland downstream of Marshall Avenue The trees near the road and extending up Tributary 2 to a road crossing to a commercial development (the road and development were constructed after the date of the aerial photography (Figure 4)) have died back as a result of flooding due to a beaver dam which has since been breached

The dominant herbaceous species within the emergent wetiands along the uimamed stream include reed canary grass Phalaris arundinacea) jewelweed Impatiens capensis) purple loosestrife Lythrum salicaria) goldeiuod species Solidago spp) red top Agrostis alba) wool grass Scirpus cyperinus) shallow sedge Carex lurida) sedge species Carex spp) sensitive fem Onoclea sensibilis) soft msh Juncus effusus) and broad-leaved cattail Typha latifolia) The dominant shmb species within the shrub swamp along the unnamed stream include alder Alnus incana) arrowwood Vibemum dentatum) grey birch Betula populifolia) elderberry Sambucus canadensis) honeysuckle Lonicera spp) and alder-buckthom Frangula alnus) The dominant tree species within the forested wetland along the unnamed stream include red maple Acer rubrum) ehn Ulmus americana) green ash Fraxinus pensylvanica)

Threatened Species Habitat Assessment

Little suitable habitat was found for either the eastern pearlshell or the eastem sand darter within the unnamed stream An approximate 1500 foot section of the unnamed stream has gravel or cobble bottom which would be considered to have low potential as habitat for the eastem sand darter This area extendsfirom just north of SD 19 to SD 35 (Figure 2) The Vermont Department of Conservation (Richard Langdon Aquatic Biologist VT DEC personal communication June 2004) concurred with Normandeaus assessment that the unnamed stream (Vermont Tributary 4 of Muddy Brook) is an unlikely place for either eastem pearlshell or the eastem sand darter to occur

Streambed characteristics were similar along the entire length of the unnamed stream with some variations in width depth and vegetative cover The unnamed stream is perennial with a narrow chaimel 2 to 5-feet wide and soft substrate bottom Flow at the time of observation was moderate (lt 1 foot per second) except behind the numerous breached beaver dams where flow is much reduced The stream charmel is generally well defined with 1 to 2 foot high banks In some areas the banks are less than 1 foot high Near the Route 2 culvert the banks were over 6 feet high Silt over fine spounduid and mud was the dominant substrate type with the exception of the sectionfi-om SD19 to SD 35 which has more gravel and cobble substrate The following species were observed within the unnamed stream fi-eshwater clam species (Sphaeriidae spp) minnow (Pimephales spp) shiner Notemigonus spp) killifish Fundulus spp) and stickleback (family Gasterosteidae) The eastem

pearlshell is a fireshwater mussel that prefers firm sand gravel or cobble in a range of flow conditions including fast-flowing mountain streams (Nedeau et al 2000) as well as quiet locations next to mshing waters where it can burrow in an upright position (Martin 1997) The eastem pearlshell also requires sahnonid species as the host for the development of the glochidia or larval stage (Nadeau et al 2000 Martin 1997) Sahnonids require cool fast flowing gravel cobble bottom streams (Richard Simmons Fisheries Biologist Normandeau Associates personal communication June 2004) which are not present in the area of study

The eastem sand darter is afi-eshwaterfish restricted to moderate size streams and large warm water rivers with clean sandy bottoms that have currents slow enough to retain sand but fast enough to prevent the deposition of silt (httpfishdnrcomelledun-fishPercidaesanddarterhtml Richard Langdon Aquatic Biologist VT DEC personal commimication June 2004) According to the Vermont Department of Environmental Conservation (VT DEC) this fish is almost always found below the Fall Line (150-foot elevation) in Vermont Littie information is available for this species but it has been reported in the Lamiolle River fom miles fi-om Lake Champlain and from the Poultaey River on the border between Vermont and New York

Richard Langdon VT DEC Aqxiatic Biologist provided three additional Vermont mussel species of concem andor threatened species that maybe found within the unnamed stream and tributaries the triangle floater Alasmidonta undulata) creek heelsplitter Lasmigona compressa) and squawfoot Strophitus undulatus) Based on a review of the literature the triangle floater can tolerate a variety of conditions including the still waters behind dams The squawfoot is uncommon and is generally a river species and the heelsplitter prefers small to medium sized rivers with fine sand or gravel substrate Normandeaus review of the urmamed stream did not specifically focus on these species but based on the current investigation the uimamed stream may provide suitable habitat for the triangle floater and the heelsplitter Further studies would have to be conducted to confirmdeny the presence of these species

50 REGULATORY OVERVIEW

The State of Vermont regulates wetiand impacts based on the wetland class as determined by the Vermont Wetland Rules The US Army Corps of Engineers (Corps) has jurisdiction over impacts to the wetiands and streams within the project area under Section 404 of the Clean Water Act However under Superfund permit equivalency the proposed work need only comply with criteria and regulations and not actaally be permitted (42 CFR 103 9621e-l)

The Vermont Wetland Rules classify wetiands into three categories Class One Two and Three The Vermont Water Resoiu-ces Board (WRB) determines Class One wetiands as exceptional or irreplaceable and merits the highest level of protection Class One wetiands must be designated by the WRB Class Two wetlands are presumed to serve one or more wetiand fimctions at a significant level The Vermont Significant Wetiand Inventory maps (VSWI) designate Class Two wetiands including most Palustrine wetlands and wetlands contiguous to mapped wetlanltis Class Three wetiands are not mapped on the VSWI maps and the WRB has not determined that these wetiands provide a significant wetiand function Class Three wetiands are not protected under the Vermont Wetiand Rules

The VSWI mapped two Class Two wetiands within the project area The wetiand north of Route 2 containing WESTON sediment sampling stations SD 25 26 28 29 (Figure 2) and a wetiand on Tributary 2 east of a commercial development access road crossing over the tributary (Figure 3) There are no Class One wetlands within the Town of Williston at this time (April Moulaert VT DEC Wetiands Ecologist personal communication June 2004) The remaining wetiands within the unnamed stream corridor are Class Three wetlands The VT DEC recommends a site review to confirm the classification of wetlands within a project area

The New England Division of the Corps has issued a Department of the Army General Permit for the State of Vermont which outiines an expedited permit process for activities with minimal wetland impacts Category A non-reportingminimal impact activities do not require a separate permit fi-om

the Corps for impacts under 3000 square feet (SF) provided that all restrictions and conditions of the General Permit are met and there are no impacts to special wetlands (fen bog and vernal pool) Category B screeningminimal impact activities include projects impacting over 3000 SF of wetiand An application is filed directly to the Corps for impacts from 5000 SF to 1 acre An individual permit fi-om the Corps is required for projects not meeting the General Permit standards

60 SUMMARY

Normandeau Associates conducted an assessment of wetland classes and threatened species habitat associated with an uimamed stream and portions of its two tributaries (Tributaries 2 and 3) in Williston Vermont for the Commerce Street Plume Project The unnamed stream channel was divided into 17 segments related to previously determined WESTON sediment sampling locations plus the immediate area of the two tributaries A total of 6697 linear feet of stream channel was reviewed and 12047 feet of wetland classified along both banks of the unnamed stream and portions of its two tributaries A habitat assessment was completed for two Vermont threatened species the eastem sand darter Ammocrypta pellucida) and eastem pearlshell mussel Margaritifera margaritifera) The assessment of the unnamed stream found no suitable habitat for these two Vermont threatened species

10 INTRODUCTION

Nomiandeau Associates (Nomiandeau) was contracted by Weston Solutions Inc (WESTON) to complete a review of an approximate 2-mile stretch of an winamed stream approximately 50-foot stretch of three tributary streams (Tributaries 12 and 3) and all associated bordering wetlands for the Commerce Street Plume Project in Williston Vermont The length of each class of wetiands bordering either bank of the stream was measured The unnamed stream and beginning portions of its three tributary streams were to be assessed for potential habitat for two Vermont listed threatened species eastem sand darter Ammocrypta pellucida) and eastem pearlshell mussel Margaritifera margaritifera) The results of the review will be used by the EPA in drafting a Hazard Ranking System package for potential listing of the Commerce Street Plume site on the National Priorities List

20 METHODOLOGY

Normandeau completed the site investigation on June 21 and 22 2004 WESTON personnel showed Normandeau the limits of the investigation access points and locations of sediment sampUng stations along the stream corridor prior to the start of the investigation The stretch of unnamed stream included in the review began approximately 750 feet north of Route 2 (Williston Road) and extended south between Harvest Lane on the east Commerce Street on the west It crossed Marshall Avenue and ended approximately 1100 feet south of the road (Figure 1) Two tributaries (Tributary 2 and Tributary 3) were also reviewed in the immediate area of where they entered the unnamed stream The confluence of Tributary 2 is located just south of Marshall Avenue The Tributary 3 confluence is approximately midway between Marshall Avenue to the south and Route 2 to the north The confluence of a third tributary (Tributary 1) is located near the Interstate 89 crossing of South Brownell Road During field activities Tributary 1 was considered outside the study area by WESTON

Wetlands

Normandeau identified wetlands bordering the unnamed stream according to the US Fish and Wildlife Service wetland classification system (Cowardin et al 1979) The wetiand class was also determined at the confluence of two tributaries with the unnamed stream Wetland identification was based on vegetation observations of indicators of hydrology and soil borings to confirm the presence of hydric soils Observations were recorded documenting wetland characteristics (Appendix A)

The start and end points of the dominant wetland class were located using a Trimblereg Global Positioning System (GPS) unit In most cases the wetland class was the same on both sides of the stream In those instances where the class differed Nomiandeau located the start and end point of the wetland class on both sides of the stream The linear length of wetland on each side of the stream was then calculated by wetland class along segments identified by WESTON

Threatened Species Habitat Assessment

A habitat assessment was conducted of the unnamed stream to identify potential suitable habitat for the Eastem Pearlshell (Margaritifera margaritifera) and the Eastem Sand Darter Ammocrypta pellucida) Both species are listed as threatened in the State of Vermont In order to minimize disturbance of the streambed substrate during observations the habitat assessment began at the downstream (southern) end of the unnamed stream corridor off South Brownell Road and continued upstream to approximately 750 feet north of Route 2 Where possible observations were made while walking in the streambed to best determine substrate type and depth Otherwise observations were made streamside A metal soil auger was used to probe the substrate to help determine sediment type and depth Notes were also made on flow rate water depth width of stream channel height of banks vegetation cover and suitability for the species of concem Habitat descriptions were recorded on field data sheets (Appendix B) For description purposes the stream was divided into segments corresponding with stream corridor GPS points and wetland identifications

GPS Location and Mapping

Normandeau located the start and end points of the wetlands and potential habitat for the eastern pearlshell and sand darter using a Trimblereg GPS luiit The GPS data were post processed to provide submeter accuracy A summary of the post processing data with a horizontal precision of 95 is provided in Appendix C Reference points were located for use in insertion onto the base map The base map was compiled using available information from the Vermont Center for Geographic Information sediment sampling stations provided by WESTON and Vermont Significant Wetland Inventory map data

30 FINDINGS

Wetlands

The wetlands bordering the unnamed stream corridor are in the Palustrine (fieshwater) system and the stream and wetlands within the channel are within the Riverine system The dominant wetland classes bordering the stream are Palustrine Emergent persistent (PEMl) and Palustrine Scmb Shrub broad-leaved deciduous (PSSl) with Palustrine Forested deciduous (PFOl) wetlands observed along the uplandwetland edge (Figures 2 3 and 4) The majority of the stream channel is classified as Riverine Lower Perennial Unconsolidated Shore sandmud (R2US23) A total of 6697 linear feet of stream channel was reviewed and 12047 feet of wetiand classified along the banks of the unnamed stream (Table 1)

Along the project corridor the wetlands bordering the unnamed stream are within the 100-year floodplain The wetland system is dynamic within the stream corridor as a result of fluctuating water levels related to a series of beaver dams several of which are shown on mapping compiled by WESTON (Appendix C) At the time of the field investigation all the dams had been breached allowing water levels to drop The upstream wetlands in the immediate area of the dams are currentiy dominated by emergent vegetation which would be expected to change to a mix of shrubs and emergent species if water levels are maintained at current levels

North of Route 2 the stream channel has been piped under an existing facility (Lot 8-105-22) The emergentshrub swamp north of the facility is approximately 300 feet wide Downstream of Route 2 the stream corridor has been impacted by development particularly fi-om Route 2 south to a point approximately 500 feet south of SDSW 18 (Lot 7-19-36) The stream channel has been ditched and the bordering wetlands range fiom 5 to 15 feet in width with the exception of an area aroimd a former beaver dam intiie vicinity of SDSW 30 (Lot 7-19-20)

Beginning at the confluence with Tributary 3 and extending downstream there have been fewer impacts to wetiands and the unnamed stream except at road crossings and along sections of the westem bank bordering the Commerce Street industrial park The stream channel is sinuous with well defined banks The bordering wetlands range from 20 to 200 feet in width and are primarily shrub swamp with emergent species in the understory and trees along the wetland edge There is a short segment of forested wetland downstream of Marshall Avenue The trees near the road and extending up Tributary 2 to a road crossing to a commercial development (the road and development were constructed after the date of the aerial photography (Figure 4)) have died back as a result of flooding due to a beaver dam which has since been breached

The dominant herbaceous species within the emergent wetiands along the uimamed stream include reed canary grass Phalaris arundinacea) jewelweed Impatiens capensis) purple loosestrife Lythrum salicaria) goldeiuod species Solidago spp) red top Agrostis alba) wool grass Scirpus cyperinus) shallow sedge Carex lurida) sedge species Carex spp) sensitive fem Onoclea sensibilis) soft msh Juncus effusus) and broad-leaved cattail Typha latifolia) The dominant shmb species within the shrub swamp along the unnamed stream include alder Alnus incana) arrowwood Vibemum dentatum) grey birch Betula populifolia) elderberry Sambucus canadensis) honeysuckle Lonicera spp) and alder-buckthom Frangula alnus) The dominant tree species within the forested wetland along the unnamed stream include red maple Acer rubrum) ehn Ulmus americana) green ash Fraxinus pensylvanica)

Threatened Species Habitat Assessment

Little suitable habitat was found for either the eastern pearlshell or the eastem sand darter within the unnamed stream An approximate 1500 foot section of the unnamed stream has gravel or cobble bottom which would be considered to have low potential as habitat for the eastem sand darter This area extendsfirom just north of SD 19 to SD 35 (Figure 2) The Vermont Department of Conservation (Richard Langdon Aquatic Biologist VT DEC personal communication June 2004) concurred with Normandeaus assessment that the unnamed stream (Vermont Tributary 4 of Muddy Brook) is an unlikely place for either eastem pearlshell or the eastem sand darter to occur

Streambed characteristics were similar along the entire length of the unnamed stream with some variations in width depth and vegetative cover The unnamed stream is perennial with a narrow chaimel 2 to 5-feet wide and soft substrate bottom Flow at the time of observation was moderate (lt 1 foot per second) except behind the numerous breached beaver dams where flow is much reduced The stream charmel is generally well defined with 1 to 2 foot high banks In some areas the banks are less than 1 foot high Near the Route 2 culvert the banks were over 6 feet high Silt over fine spounduid and mud was the dominant substrate type with the exception of the sectionfi-om SD19 to SD 35 which has more gravel and cobble substrate The following species were observed within the unnamed stream fi-eshwater clam species (Sphaeriidae spp) minnow (Pimephales spp) shiner Notemigonus spp) killifish Fundulus spp) and stickleback (family Gasterosteidae) The eastem

pearlshell is a fireshwater mussel that prefers firm sand gravel or cobble in a range of flow conditions including fast-flowing mountain streams (Nedeau et al 2000) as well as quiet locations next to mshing waters where it can burrow in an upright position (Martin 1997) The eastem pearlshell also requires sahnonid species as the host for the development of the glochidia or larval stage (Nadeau et al 2000 Martin 1997) Sahnonids require cool fast flowing gravel cobble bottom streams (Richard Simmons Fisheries Biologist Normandeau Associates personal communication June 2004) which are not present in the area of study

The eastem sand darter is afi-eshwaterfish restricted to moderate size streams and large warm water rivers with clean sandy bottoms that have currents slow enough to retain sand but fast enough to prevent the deposition of silt (httpfishdnrcomelledun-fishPercidaesanddarterhtml Richard Langdon Aquatic Biologist VT DEC personal commimication June 2004) According to the Vermont Department of Environmental Conservation (VT DEC) this fish is almost always found below the Fall Line (150-foot elevation) in Vermont Littie information is available for this species but it has been reported in the Lamiolle River fom miles fi-om Lake Champlain and from the Poultaey River on the border between Vermont and New York

Richard Langdon VT DEC Aqxiatic Biologist provided three additional Vermont mussel species of concem andor threatened species that maybe found within the unnamed stream and tributaries the triangle floater Alasmidonta undulata) creek heelsplitter Lasmigona compressa) and squawfoot Strophitus undulatus) Based on a review of the literature the triangle floater can tolerate a variety of conditions including the still waters behind dams The squawfoot is uncommon and is generally a river species and the heelsplitter prefers small to medium sized rivers with fine sand or gravel substrate Normandeaus review of the urmamed stream did not specifically focus on these species but based on the current investigation the uimamed stream may provide suitable habitat for the triangle floater and the heelsplitter Further studies would have to be conducted to confirmdeny the presence of these species

50 REGULATORY OVERVIEW

The State of Vermont regulates wetiand impacts based on the wetland class as determined by the Vermont Wetland Rules The US Army Corps of Engineers (Corps) has jurisdiction over impacts to the wetiands and streams within the project area under Section 404 of the Clean Water Act However under Superfund permit equivalency the proposed work need only comply with criteria and regulations and not actaally be permitted (42 CFR 103 9621e-l)

The Vermont Wetland Rules classify wetiands into three categories Class One Two and Three The Vermont Water Resoiu-ces Board (WRB) determines Class One wetiands as exceptional or irreplaceable and merits the highest level of protection Class One wetiands must be designated by the WRB Class Two wetlands are presumed to serve one or more wetiand fimctions at a significant level The Vermont Significant Wetiand Inventory maps (VSWI) designate Class Two wetiands including most Palustrine wetlands and wetlands contiguous to mapped wetlanltis Class Three wetiands are not mapped on the VSWI maps and the WRB has not determined that these wetiands provide a significant wetiand function Class Three wetiands are not protected under the Vermont Wetiand Rules

The VSWI mapped two Class Two wetiands within the project area The wetiand north of Route 2 containing WESTON sediment sampling stations SD 25 26 28 29 (Figure 2) and a wetiand on Tributary 2 east of a commercial development access road crossing over the tributary (Figure 3) There are no Class One wetlands within the Town of Williston at this time (April Moulaert VT DEC Wetiands Ecologist personal communication June 2004) The remaining wetiands within the unnamed stream corridor are Class Three wetlands The VT DEC recommends a site review to confirm the classification of wetlands within a project area

The New England Division of the Corps has issued a Department of the Army General Permit for the State of Vermont which outiines an expedited permit process for activities with minimal wetland impacts Category A non-reportingminimal impact activities do not require a separate permit fi-om

the Corps for impacts under 3000 square feet (SF) provided that all restrictions and conditions of the General Permit are met and there are no impacts to special wetlands (fen bog and vernal pool) Category B screeningminimal impact activities include projects impacting over 3000 SF of wetiand An application is filed directly to the Corps for impacts from 5000 SF to 1 acre An individual permit fi-om the Corps is required for projects not meeting the General Permit standards

60 SUMMARY

Normandeau Associates conducted an assessment of wetland classes and threatened species habitat associated with an uimamed stream and portions of its two tributaries (Tributaries 2 and 3) in Williston Vermont for the Commerce Street Plume Project The unnamed stream channel was divided into 17 segments related to previously determined WESTON sediment sampling locations plus the immediate area of the two tributaries A total of 6697 linear feet of stream channel was reviewed and 12047 feet of wetland classified along both banks of the unnamed stream and portions of its two tributaries A habitat assessment was completed for two Vermont threatened species the eastem sand darter Ammocrypta pellucida) and eastem pearlshell mussel Margaritifera margaritifera) The assessment of the unnamed stream found no suitable habitat for these two Vermont threatened species

10 INTRODUCTION

Nomiandeau Associates (Nomiandeau) was contracted by Weston Solutions Inc (WESTON) to complete a review of an approximate 2-mile stretch of an winamed stream approximately 50-foot stretch of three tributary streams (Tributaries 12 and 3) and all associated bordering wetlands for the Commerce Street Plume Project in Williston Vermont The length of each class of wetiands bordering either bank of the stream was measured The unnamed stream and beginning portions of its three tributary streams were to be assessed for potential habitat for two Vermont listed threatened species eastem sand darter Ammocrypta pellucida) and eastem pearlshell mussel Margaritifera margaritifera) The results of the review will be used by the EPA in drafting a Hazard Ranking System package for potential listing of the Commerce Street Plume site on the National Priorities List

Normandeau completed the site investigation on June 21 and 22 2004 WESTON personnel showed Normandeau the limits of the investigation access points and locations of sediment sampUng stations along the stream corridor prior to the start of the investigation The stretch of unnamed stream included in the review began approximately 750 feet north of Route 2 (Williston Road) and extended south between Harvest Lane on the east Commerce Street on the west It crossed Marshall Avenue and ended approximately 1100 feet south of the road (Figure 1) Two tributaries (Tributary 2 and Tributary 3) were also reviewed in the immediate area of where they entered the unnamed stream The confluence of Tributary 2 is located just south of Marshall Avenue The Tributary 3 confluence is approximately midway between Marshall Avenue to the south and Route 2 to the north The confluence of a third tributary (Tributary 1) is located near the Interstate 89 crossing of South Brownell Road During field activities Tributary 1 was considered outside the study area by WESTON

Wetlands

Normandeau identified wetlands bordering the unnamed stream according to the US Fish and Wildlife Service wetland classification system (Cowardin et al 1979) The wetiand class was also determined at the confluence of two tributaries with the unnamed stream Wetland identification was based on vegetation observations of indicators of hydrology and soil borings to confirm the presence of hydric soils Observations were recorded documenting wetland characteristics (Appendix A)

The start and end points of the dominant wetland class were located using a Trimblereg Global Positioning System (GPS) unit In most cases the wetland class was the same on both sides of the stream In those instances where the class differed Nomiandeau located the start and end point of the wetland class on both sides of the stream The linear length of wetland on each side of the stream was then calculated by wetland class along segments identified by WESTON

Threatened Species Habitat Assessment

A habitat assessment was conducted of the unnamed stream to identify potential suitable habitat for the Eastem Pearlshell (Margaritifera margaritifera) and the Eastem Sand Darter Ammocrypta pellucida) Both species are listed as threatened in the State of Vermont In order to minimize disturbance of the streambed substrate during observations the habitat assessment began at the downstream (southern) end of the unnamed stream corridor off South Brownell Road and continued upstream to approximately 750 feet north of Route 2 Where possible observations were made while walking in the streambed to best determine substrate type and depth Otherwise observations were made streamside A metal soil auger was used to probe the substrate to help determine sediment type and depth Notes were also made on flow rate water depth width of stream channel height of banks vegetation cover and suitability for the species of concem Habitat descriptions were recorded on field data sheets (Appendix B) For description purposes the stream was divided into segments corresponding with stream corridor GPS points and wetland identifications

GPS Location and Mapping

Normandeau located the start and end points of the wetlands and potential habitat for the eastern pearlshell and sand darter using a Trimblereg GPS luiit The GPS data were post processed to provide submeter accuracy A summary of the post processing data with a horizontal precision of 95 is provided in Appendix C Reference points were located for use in insertion onto the base map The base map was compiled using available information from the Vermont Center for Geographic Information sediment sampling stations provided by WESTON and Vermont Significant Wetland Inventory map data

30 FINDINGS

Wetlands

The wetlands bordering the unnamed stream corridor are in the Palustrine (fieshwater) system and the stream and wetlands within the channel are within the Riverine system The dominant wetland classes bordering the stream are Palustrine Emergent persistent (PEMl) and Palustrine Scmb Shrub broad-leaved deciduous (PSSl) with Palustrine Forested deciduous (PFOl) wetlands observed along the uplandwetland edge (Figures 2 3 and 4) The majority of the stream channel is classified as Riverine Lower Perennial Unconsolidated Shore sandmud (R2US23) A total of 6697 linear feet of stream channel was reviewed and 12047 feet of wetiand classified along the banks of the unnamed stream (Table 1)

Along the project corridor the wetlands bordering the unnamed stream are within the 100-year floodplain The wetland system is dynamic within the stream corridor as a result of fluctuating water levels related to a series of beaver dams several of which are shown on mapping compiled by WESTON (Appendix C) At the time of the field investigation all the dams had been breached allowing water levels to drop The upstream wetlands in the immediate area of the dams are currentiy dominated by emergent vegetation which would be expected to change to a mix of shrubs and emergent species if water levels are maintained at current levels

North of Route 2 the stream channel has been piped under an existing facility (Lot 8-105-22) The emergentshrub swamp north of the facility is approximately 300 feet wide Downstream of Route 2 the stream corridor has been impacted by development particularly fi-om Route 2 south to a point approximately 500 feet south of SDSW 18 (Lot 7-19-36) The stream channel has been ditched and the bordering wetlands range fiom 5 to 15 feet in width with the exception of an area aroimd a former beaver dam intiie vicinity of SDSW 30 (Lot 7-19-20)

Beginning at the confluence with Tributary 3 and extending downstream there have been fewer impacts to wetiands and the unnamed stream except at road crossings and along sections of the westem bank bordering the Commerce Street industrial park The stream channel is sinuous with well defined banks The bordering wetlands range from 20 to 200 feet in width and are primarily shrub swamp with emergent species in the understory and trees along the wetland edge There is a short segment of forested wetland downstream of Marshall Avenue The trees near the road and extending up Tributary 2 to a road crossing to a commercial development (the road and development were constructed after the date of the aerial photography (Figure 4)) have died back as a result of flooding due to a beaver dam which has since been breached

The dominant herbaceous species within the emergent wetiands along the uimamed stream include reed canary grass Phalaris arundinacea) jewelweed Impatiens capensis) purple loosestrife Lythrum salicaria) goldeiuod species Solidago spp) red top Agrostis alba) wool grass Scirpus cyperinus) shallow sedge Carex lurida) sedge species Carex spp) sensitive fem Onoclea sensibilis) soft msh Juncus effusus) and broad-leaved cattail Typha latifolia) The dominant shmb species within the shrub swamp along the unnamed stream include alder Alnus incana) arrowwood Vibemum dentatum) grey birch Betula populifolia) elderberry Sambucus canadensis) honeysuckle Lonicera spp) and alder-buckthom Frangula alnus) The dominant tree species within the forested wetland along the unnamed stream include red maple Acer rubrum) ehn Ulmus americana) green ash Fraxinus pensylvanica)

Threatened Species Habitat Assessment

Little suitable habitat was found for either the eastern pearlshell or the eastem sand darter within the unnamed stream An approximate 1500 foot section of the unnamed stream has gravel or cobble bottom which would be considered to have low potential as habitat for the eastem sand darter This area extendsfirom just north of SD 19 to SD 35 (Figure 2) The Vermont Department of Conservation (Richard Langdon Aquatic Biologist VT DEC personal communication June 2004) concurred with Normandeaus assessment that the unnamed stream (Vermont Tributary 4 of Muddy Brook) is an unlikely place for either eastem pearlshell or the eastem sand darter to occur

Streambed characteristics were similar along the entire length of the unnamed stream with some variations in width depth and vegetative cover The unnamed stream is perennial with a narrow chaimel 2 to 5-feet wide and soft substrate bottom Flow at the time of observation was moderate (lt 1 foot per second) except behind the numerous breached beaver dams where flow is much reduced The stream charmel is generally well defined with 1 to 2 foot high banks In some areas the banks are less than 1 foot high Near the Route 2 culvert the banks were over 6 feet high Silt over fine spounduid and mud was the dominant substrate type with the exception of the sectionfi-om SD19 to SD 35 which has more gravel and cobble substrate The following species were observed within the unnamed stream fi-eshwater clam species (Sphaeriidae spp) minnow (Pimephales spp) shiner Notemigonus spp) killifish Fundulus spp) and stickleback (family Gasterosteidae) The eastem

pearlshell is a fireshwater mussel that prefers firm sand gravel or cobble in a range of flow conditions including fast-flowing mountain streams (Nedeau et al 2000) as well as quiet locations next to mshing waters where it can burrow in an upright position (Martin 1997) The eastem pearlshell also requires sahnonid species as the host for the development of the glochidia or larval stage (Nadeau et al 2000 Martin 1997) Sahnonids require cool fast flowing gravel cobble bottom streams (Richard Simmons Fisheries Biologist Normandeau Associates personal communication June 2004) which are not present in the area of study

The eastem sand darter is afi-eshwaterfish restricted to moderate size streams and large warm water rivers with clean sandy bottoms that have currents slow enough to retain sand but fast enough to prevent the deposition of silt (httpfishdnrcomelledun-fishPercidaesanddarterhtml Richard Langdon Aquatic Biologist VT DEC personal commimication June 2004) According to the Vermont Department of Environmental Conservation (VT DEC) this fish is almost always found below the Fall Line (150-foot elevation) in Vermont Littie information is available for this species but it has been reported in the Lamiolle River fom miles fi-om Lake Champlain and from the Poultaey River on the border between Vermont and New York

Richard Langdon VT DEC Aqxiatic Biologist provided three additional Vermont mussel species of concem andor threatened species that maybe found within the unnamed stream and tributaries the triangle floater Alasmidonta undulata) creek heelsplitter Lasmigona compressa) and squawfoot Strophitus undulatus) Based on a review of the literature the triangle floater can tolerate a variety of conditions including the still waters behind dams The squawfoot is uncommon and is generally a river species and the heelsplitter prefers small to medium sized rivers with fine sand or gravel substrate Normandeaus review of the urmamed stream did not specifically focus on these species but based on the current investigation the uimamed stream may provide suitable habitat for the triangle floater and the heelsplitter Further studies would have to be conducted to confirmdeny the presence of these species

50 REGULATORY OVERVIEW

The State of Vermont regulates wetiand impacts based on the wetland class as determined by the Vermont Wetland Rules The US Army Corps of Engineers (Corps) has jurisdiction over impacts to the wetiands and streams within the project area under Section 404 of the Clean Water Act However under Superfund permit equivalency the proposed work need only comply with criteria and regulations and not actaally be permitted (42 CFR 103 9621e-l)

The Vermont Wetland Rules classify wetiands into three categories Class One Two and Three The Vermont Water Resoiu-ces Board (WRB) determines Class One wetiands as exceptional or irreplaceable and merits the highest level of protection Class One wetiands must be designated by the WRB Class Two wetlands are presumed to serve one or more wetiand fimctions at a significant level The Vermont Significant Wetiand Inventory maps (VSWI) designate Class Two wetiands including most Palustrine wetlands and wetlands contiguous to mapped wetlanltis Class Three wetiands are not mapped on the VSWI maps and the WRB has not determined that these wetiands provide a significant wetiand function Class Three wetiands are not protected under the Vermont Wetiand Rules

The VSWI mapped two Class Two wetiands within the project area The wetiand north of Route 2 containing WESTON sediment sampling stations SD 25 26 28 29 (Figure 2) and a wetiand on Tributary 2 east of a commercial development access road crossing over the tributary (Figure 3) There are no Class One wetlands within the Town of Williston at this time (April Moulaert VT DEC Wetiands Ecologist personal communication June 2004) The remaining wetiands within the unnamed stream corridor are Class Three wetlands The VT DEC recommends a site review to confirm the classification of wetlands within a project area

The New England Division of the Corps has issued a Department of the Army General Permit for the State of Vermont which outiines an expedited permit process for activities with minimal wetland impacts Category A non-reportingminimal impact activities do not require a separate permit fi-om

the Corps for impacts under 3000 square feet (SF) provided that all restrictions and conditions of the General Permit are met and there are no impacts to special wetlands (fen bog and vernal pool) Category B screeningminimal impact activities include projects impacting over 3000 SF of wetiand An application is filed directly to the Corps for impacts from 5000 SF to 1 acre An individual permit fi-om the Corps is required for projects not meeting the General Permit standards

60 SUMMARY

Normandeau Associates conducted an assessment of wetland classes and threatened species habitat associated with an uimamed stream and portions of its two tributaries (Tributaries 2 and 3) in Williston Vermont for the Commerce Street Plume Project The unnamed stream channel was divided into 17 segments related to previously determined WESTON sediment sampling locations plus the immediate area of the two tributaries A total of 6697 linear feet of stream channel was reviewed and 12047 feet of wetland classified along both banks of the unnamed stream and portions of its two tributaries A habitat assessment was completed for two Vermont threatened species the eastem sand darter Ammocrypta pellucida) and eastem pearlshell mussel Margaritifera margaritifera) The assessment of the unnamed stream found no suitable habitat for these two Vermont threatened species

Commerce Street Plume Project

10 INTRODUCTION

Nomiandeau Associates (Nomiandeau) was contracted by Weston Solutions Inc (WESTON) to complete a review of an approximate 2-mile stretch of an winamed stream approximately 50-foot stretch of three tributary streams (Tributaries 12 and 3) and all associated bordering wetlands for the Commerce Street Plume Project in Williston Vermont The length of each class of wetiands bordering either bank of the stream was measured The unnamed stream and beginning portions of its three tributary streams were to be assessed for potential habitat for two Vermont listed threatened species eastem sand darter Ammocrypta pellucida) and eastem pearlshell mussel Margaritifera margaritifera) The results of the review will be used by the EPA in drafting a Hazard Ranking System package for potential listing of the Commerce Street Plume site on the National Priorities List

20 METHODOLOGY

Normandeau completed the site investigation on June 21 and 22 2004 WESTON personnel showed Normandeau the limits of the investigation access points and locations of sediment sampUng stations along the stream corridor prior to the start of the investigation The stretch of unnamed stream included in the review began approximately 750 feet north of Route 2 (Williston Road) and extended south between Harvest Lane on the east Commerce Street on the west It crossed Marshall Avenue and ended approximately 1100 feet south of the road (Figure 1) Two tributaries (Tributary 2 and Tributary 3) were also reviewed in the immediate area of where they entered the unnamed stream The confluence of Tributary 2 is located just south of Marshall Avenue The Tributary 3 confluence is approximately midway between Marshall Avenue to the south and Route 2 to the north The confluence of a third tributary (Tributary 1) is located near the Interstate 89 crossing of South Brownell Road During field activities Tributary 1 was considered outside the study area by WESTON

Wetlands

Normandeau identified wetlands bordering the unnamed stream according to the US Fish and Wildlife Service wetland classification system (Cowardin et al 1979) The wetiand class was also determined at the confluence of two tributaries with the unnamed stream Wetland identification was based on vegetation observations of indicators of hydrology and soil borings to confirm the presence of hydric soils Observations were recorded documenting wetland characteristics (Appendix A)

The start and end points of the dominant wetland class were located using a Trimblereg Global Positioning System (GPS) unit In most cases the wetland class was the same on both sides of the stream In those instances where the class differed Nomiandeau located the start and end point of the wetland class on both sides of the stream The linear length of wetland on each side of the stream was then calculated by wetland class along segments identified by WESTON

Threatened Species Habitat Assessment

A habitat assessment was conducted of the unnamed stream to identify potential suitable habitat for the Eastem Pearlshell (Margaritifera margaritifera) and the Eastem Sand Darter Ammocrypta pellucida) Both species are listed as threatened in the State of Vermont In order to minimize disturbance of the streambed substrate during observations the habitat assessment began at the downstream (southern) end of the unnamed stream corridor off South Brownell Road and continued upstream to approximately 750 feet north of Route 2 Where possible observations were made while walking in the streambed to best determine substrate type and depth Otherwise observations were made streamside A metal soil auger was used to probe the substrate to help determine sediment type and depth Notes were also made on flow rate water depth width of stream channel height of banks vegetation cover and suitability for the species of concem Habitat descriptions were recorded on field data sheets (Appendix B) For description purposes the stream was divided into segments corresponding with stream corridor GPS points and wetland identifications

GPS Location and Mapping

Normandeau located the start and end points of the wetlands and potential habitat for the eastern pearlshell and sand darter using a Trimblereg GPS luiit The GPS data were post processed to provide submeter accuracy A summary of the post processing data with a horizontal precision of 95 is provided in Appendix C Reference points were located for use in insertion onto the base map The base map was compiled using available information from the Vermont Center for Geographic Information sediment sampling stations provided by WESTON and Vermont Significant Wetland Inventory map data

30 FINDINGS

Wetlands

The wetlands bordering the unnamed stream corridor are in the Palustrine (fieshwater) system and the stream and wetlands within the channel are within the Riverine system The dominant wetland classes bordering the stream are Palustrine Emergent persistent (PEMl) and Palustrine Scmb Shrub broad-leaved deciduous (PSSl) with Palustrine Forested deciduous (PFOl) wetlands observed along the uplandwetland edge (Figures 2 3 and 4) The majority of the stream channel is classified as Riverine Lower Perennial Unconsolidated Shore sandmud (R2US23) A total of 6697 linear feet of stream channel was reviewed and 12047 feet of wetiand classified along the banks of the unnamed stream (Table 1)

Along the project corridor the wetlands bordering the unnamed stream are within the 100-year floodplain The wetland system is dynamic within the stream corridor as a result of fluctuating water levels related to a series of beaver dams several of which are shown on mapping compiled by WESTON (Appendix C) At the time of the field investigation all the dams had been breached allowing water levels to drop The upstream wetlands in the immediate area of the dams are currentiy dominated by emergent vegetation which would be expected to change to a mix of shrubs and emergent species if water levels are maintained at current levels

North of Route 2 the stream channel has been piped under an existing facility (Lot 8-105-22) The emergentshrub swamp north of the facility is approximately 300 feet wide Downstream of Route 2 the stream corridor has been impacted by development particularly fi-om Route 2 south to a point approximately 500 feet south of SDSW 18 (Lot 7-19-36) The stream channel has been ditched and the bordering wetlands range fiom 5 to 15 feet in width with the exception of an area aroimd a former beaver dam intiie vicinity of SDSW 30 (Lot 7-19-20)

Beginning at the confluence with Tributary 3 and extending downstream there have been fewer impacts to wetiands and the unnamed stream except at road crossings and along sections of the westem bank bordering the Commerce Street industrial park The stream channel is sinuous with well defined banks The bordering wetlands range from 20 to 200 feet in width and are primarily shrub swamp with emergent species in the understory and trees along the wetland edge There is a short segment of forested wetland downstream of Marshall Avenue The trees near the road and extending up Tributary 2 to a road crossing to a commercial development (the road and development were constructed after the date of the aerial photography (Figure 4)) have died back as a result of flooding due to a beaver dam which has since been breached

The dominant herbaceous species within the emergent wetiands along the uimamed stream include reed canary grass Phalaris arundinacea) jewelweed Impatiens capensis) purple loosestrife Lythrum salicaria) goldeiuod species Solidago spp) red top Agrostis alba) wool grass Scirpus cyperinus) shallow sedge Carex lurida) sedge species Carex spp) sensitive fem Onoclea sensibilis) soft msh Juncus effusus) and broad-leaved cattail Typha latifolia) The dominant shmb species within the shrub swamp along the unnamed stream include alder Alnus incana) arrowwood Vibemum dentatum) grey birch Betula populifolia) elderberry Sambucus canadensis) honeysuckle Lonicera spp) and alder-buckthom Frangula alnus) The dominant tree species within the forested wetland along the unnamed stream include red maple Acer rubrum) ehn Ulmus americana) green ash Fraxinus pensylvanica)

Threatened Species Habitat Assessment

Little suitable habitat was found for either the eastern pearlshell or the eastem sand darter within the unnamed stream An approximate 1500 foot section of the unnamed stream has gravel or cobble bottom which would be considered to have low potential as habitat for the eastem sand darter This area extendsfirom just north of SD 19 to SD 35 (Figure 2) The Vermont Department of Conservation (Richard Langdon Aquatic Biologist VT DEC personal communication June 2004) concurred with Normandeaus assessment that the unnamed stream (Vermont Tributary 4 of Muddy Brook) is an unlikely place for either eastem pearlshell or the eastem sand darter to occur

Streambed characteristics were similar along the entire length of the unnamed stream with some variations in width depth and vegetative cover The unnamed stream is perennial with a narrow chaimel 2 to 5-feet wide and soft substrate bottom Flow at the time of observation was moderate (lt 1 foot per second) except behind the numerous breached beaver dams where flow is much reduced The stream charmel is generally well defined with 1 to 2 foot high banks In some areas the banks are less than 1 foot high Near the Route 2 culvert the banks were over 6 feet high Silt over fine spounduid and mud was the dominant substrate type with the exception of the sectionfi-om SD19 to SD 35 which has more gravel and cobble substrate The following species were observed within the unnamed stream fi-eshwater clam species (Sphaeriidae spp) minnow (Pimephales spp) shiner Notemigonus spp) killifish Fundulus spp) and stickleback (family Gasterosteidae) The eastem

pearlshell is a fireshwater mussel that prefers firm sand gravel or cobble in a range of flow conditions including fast-flowing mountain streams (Nedeau et al 2000) as well as quiet locations next to mshing waters where it can burrow in an upright position (Martin 1997) The eastem pearlshell also requires sahnonid species as the host for the development of the glochidia or larval stage (Nadeau et al 2000 Martin 1997) Sahnonids require cool fast flowing gravel cobble bottom streams (Richard Simmons Fisheries Biologist Normandeau Associates personal communication June 2004) which are not present in the area of study

The eastem sand darter is afi-eshwaterfish restricted to moderate size streams and large warm water rivers with clean sandy bottoms that have currents slow enough to retain sand but fast enough to prevent the deposition of silt (httpfishdnrcomelledun-fishPercidaesanddarterhtml Richard Langdon Aquatic Biologist VT DEC personal commimication June 2004) According to the Vermont Department of Environmental Conservation (VT DEC) this fish is almost always found below the Fall Line (150-foot elevation) in Vermont Littie information is available for this species but it has been reported in the Lamiolle River fom miles fi-om Lake Champlain and from the Poultaey River on the border between Vermont and New York

Richard Langdon VT DEC Aqxiatic Biologist provided three additional Vermont mussel species of concem andor threatened species that maybe found within the unnamed stream and tributaries the triangle floater Alasmidonta undulata) creek heelsplitter Lasmigona compressa) and squawfoot Strophitus undulatus) Based on a review of the literature the triangle floater can tolerate a variety of conditions including the still waters behind dams The squawfoot is uncommon and is generally a river species and the heelsplitter prefers small to medium sized rivers with fine sand or gravel substrate Normandeaus review of the urmamed stream did not specifically focus on these species but based on the current investigation the uimamed stream may provide suitable habitat for the triangle floater and the heelsplitter Further studies would have to be conducted to confirmdeny the presence of these species

50 REGULATORY OVERVIEW

The State of Vermont regulates wetiand impacts based on the wetland class as determined by the Vermont Wetland Rules The US Army Corps of Engineers (Corps) has jurisdiction over impacts to the wetiands and streams within the project area under Section 404 of the Clean Water Act However under Superfund permit equivalency the proposed work need only comply with criteria and regulations and not actaally be permitted (42 CFR 103 9621e-l)

The Vermont Wetland Rules classify wetiands into three categories Class One Two and Three The Vermont Water Resoiu-ces Board (WRB) determines Class One wetiands as exceptional or irreplaceable and merits the highest level of protection Class One wetiands must be designated by the WRB Class Two wetlands are presumed to serve one or more wetiand fimctions at a significant level The Vermont Significant Wetiand Inventory maps (VSWI) designate Class Two wetiands including most Palustrine wetlands and wetlands contiguous to mapped wetlanltis Class Three wetiands are not mapped on the VSWI maps and the WRB has not determined that these wetiands provide a significant wetiand function Class Three wetiands are not protected under the Vermont Wetiand Rules

The VSWI mapped two Class Two wetiands within the project area The wetiand north of Route 2 containing WESTON sediment sampling stations SD 25 26 28 29 (Figure 2) and a wetiand on Tributary 2 east of a commercial development access road crossing over the tributary (Figure 3) There are no Class One wetlands within the Town of Williston at this time (April Moulaert VT DEC Wetiands Ecologist personal communication June 2004) The remaining wetiands within the unnamed stream corridor are Class Three wetlands The VT DEC recommends a site review to confirm the classification of wetlands within a project area

The New England Division of the Corps has issued a Department of the Army General Permit for the State of Vermont which outiines an expedited permit process for activities with minimal wetland impacts Category A non-reportingminimal impact activities do not require a separate permit fi-om

the Corps for impacts under 3000 square feet (SF) provided that all restrictions and conditions of the General Permit are met and there are no impacts to special wetlands (fen bog and vernal pool) Category B screeningminimal impact activities include projects impacting over 3000 SF of wetiand An application is filed directly to the Corps for impacts from 5000 SF to 1 acre An individual permit fi-om the Corps is required for projects not meeting the General Permit standards

60 SUMMARY

Normandeau Associates conducted an assessment of wetland classes and threatened species habitat associated with an uimamed stream and portions of its two tributaries (Tributaries 2 and 3) in Williston Vermont for the Commerce Street Plume Project The unnamed stream channel was divided into 17 segments related to previously determined WESTON sediment sampling locations plus the immediate area of the two tributaries A total of 6697 linear feet of stream channel was reviewed and 12047 feet of wetland classified along both banks of the unnamed stream and portions of its two tributaries A habitat assessment was completed for two Vermont threatened species the eastem sand darter Ammocrypta pellucida) and eastem pearlshell mussel Margaritifera margaritifera) The assessment of the unnamed stream found no suitable habitat for these two Vermont threatened species

Threatened Species Habitat Assessment

A habitat assessment was conducted of the unnamed stream to identify potential suitable habitat for the Eastem Pearlshell (Margaritifera margaritifera) and the Eastem Sand Darter Ammocrypta pellucida) Both species are listed as threatened in the State of Vermont In order to minimize disturbance of the streambed substrate during observations the habitat assessment began at the downstream (southern) end of the unnamed stream corridor off South Brownell Road and continued upstream to approximately 750 feet north of Route 2 Where possible observations were made while walking in the streambed to best determine substrate type and depth Otherwise observations were made streamside A metal soil auger was used to probe the substrate to help determine sediment type and depth Notes were also made on flow rate water depth width of stream channel height of banks vegetation cover and suitability for the species of concem Habitat descriptions were recorded on field data sheets (Appendix B) For description purposes the stream was divided into segments corresponding with stream corridor GPS points and wetland identifications

GPS Location and Mapping

Normandeau located the start and end points of the wetlands and potential habitat for the eastern pearlshell and sand darter using a Trimblereg GPS luiit The GPS data were post processed to provide submeter accuracy A summary of the post processing data with a horizontal precision of 95 is provided in Appendix C Reference points were located for use in insertion onto the base map The base map was compiled using available information from the Vermont Center for Geographic Information sediment sampling stations provided by WESTON and Vermont Significant Wetland Inventory map data

30 FINDINGS

Wetlands

The wetlands bordering the unnamed stream corridor are in the Palustrine (fieshwater) system and the stream and wetlands within the channel are within the Riverine system The dominant wetland classes bordering the stream are Palustrine Emergent persistent (PEMl) and Palustrine Scmb Shrub broad-leaved deciduous (PSSl) with Palustrine Forested deciduous (PFOl) wetlands observed along the uplandwetland edge (Figures 2 3 and 4) The majority of the stream channel is classified as Riverine Lower Perennial Unconsolidated Shore sandmud (R2US23) A total of 6697 linear feet of stream channel was reviewed and 12047 feet of wetiand classified along the banks of the unnamed stream (Table 1)

Along the project corridor the wetlands bordering the unnamed stream are within the 100-year floodplain The wetland system is dynamic within the stream corridor as a result of fluctuating water levels related to a series of beaver dams several of which are shown on mapping compiled by WESTON (Appendix C) At the time of the field investigation all the dams had been breached allowing water levels to drop The upstream wetlands in the immediate area of the dams are currentiy dominated by emergent vegetation which would be expected to change to a mix of shrubs and emergent species if water levels are maintained at current levels

North of Route 2 the stream channel has been piped under an existing facility (Lot 8-105-22) The emergentshrub swamp north of the facility is approximately 300 feet wide Downstream of Route 2 the stream corridor has been impacted by development particularly fi-om Route 2 south to a point approximately 500 feet south of SDSW 18 (Lot 7-19-36) The stream channel has been ditched and the bordering wetlands range fiom 5 to 15 feet in width with the exception of an area aroimd a former beaver dam intiie vicinity of SDSW 30 (Lot 7-19-20)

Beginning at the confluence with Tributary 3 and extending downstream there have been fewer impacts to wetiands and the unnamed stream except at road crossings and along sections of the westem bank bordering the Commerce Street industrial park The stream channel is sinuous with well defined banks The bordering wetlands range from 20 to 200 feet in width and are primarily shrub swamp with emergent species in the understory and trees along the wetland edge There is a short segment of forested wetland downstream of Marshall Avenue The trees near the road and extending up Tributary 2 to a road crossing to a commercial development (the road and development were constructed after the date of the aerial photography (Figure 4)) have died back as a result of flooding due to a beaver dam which has since been breached

The dominant herbaceous species within the emergent wetiands along the uimamed stream include reed canary grass Phalaris arundinacea) jewelweed Impatiens capensis) purple loosestrife Lythrum salicaria) goldeiuod species Solidago spp) red top Agrostis alba) wool grass Scirpus cyperinus) shallow sedge Carex lurida) sedge species Carex spp) sensitive fem Onoclea sensibilis) soft msh Juncus effusus) and broad-leaved cattail Typha latifolia) The dominant shmb species within the shrub swamp along the unnamed stream include alder Alnus incana) arrowwood Vibemum dentatum) grey birch Betula populifolia) elderberry Sambucus canadensis) honeysuckle Lonicera spp) and alder-buckthom Frangula alnus) The dominant tree species within the forested wetland along the unnamed stream include red maple Acer rubrum) ehn Ulmus americana) green ash Fraxinus pensylvanica)

Threatened Species Habitat Assessment

Little suitable habitat was found for either the eastern pearlshell or the eastem sand darter within the unnamed stream An approximate 1500 foot section of the unnamed stream has gravel or cobble bottom which would be considered to have low potential as habitat for the eastem sand darter This area extendsfirom just north of SD 19 to SD 35 (Figure 2) The Vermont Department of Conservation (Richard Langdon Aquatic Biologist VT DEC personal communication June 2004) concurred with Normandeaus assessment that the unnamed stream (Vermont Tributary 4 of Muddy Brook) is an unlikely place for either eastem pearlshell or the eastem sand darter to occur

Streambed characteristics were similar along the entire length of the unnamed stream with some variations in width depth and vegetative cover The unnamed stream is perennial with a narrow chaimel 2 to 5-feet wide and soft substrate bottom Flow at the time of observation was moderate (lt 1 foot per second) except behind the numerous breached beaver dams where flow is much reduced The stream charmel is generally well defined with 1 to 2 foot high banks In some areas the banks are less than 1 foot high Near the Route 2 culvert the banks were over 6 feet high Silt over fine spounduid and mud was the dominant substrate type with the exception of the sectionfi-om SD19 to SD 35 which has more gravel and cobble substrate The following species were observed within the unnamed stream fi-eshwater clam species (Sphaeriidae spp) minnow (Pimephales spp) shiner Notemigonus spp) killifish Fundulus spp) and stickleback (family Gasterosteidae) The eastem

pearlshell is a fireshwater mussel that prefers firm sand gravel or cobble in a range of flow conditions including fast-flowing mountain streams (Nedeau et al 2000) as well as quiet locations next to mshing waters where it can burrow in an upright position (Martin 1997) The eastem pearlshell also requires sahnonid species as the host for the development of the glochidia or larval stage (Nadeau et al 2000 Martin 1997) Sahnonids require cool fast flowing gravel cobble bottom streams (Richard Simmons Fisheries Biologist Normandeau Associates personal communication June 2004) which are not present in the area of study

The eastem sand darter is afi-eshwaterfish restricted to moderate size streams and large warm water rivers with clean sandy bottoms that have currents slow enough to retain sand but fast enough to prevent the deposition of silt (httpfishdnrcomelledun-fishPercidaesanddarterhtml Richard Langdon Aquatic Biologist VT DEC personal commimication June 2004) According to the Vermont Department of Environmental Conservation (VT DEC) this fish is almost always found below the Fall Line (150-foot elevation) in Vermont Littie information is available for this species but it has been reported in the Lamiolle River fom miles fi-om Lake Champlain and from the Poultaey River on the border between Vermont and New York

Richard Langdon VT DEC Aqxiatic Biologist provided three additional Vermont mussel species of concem andor threatened species that maybe found within the unnamed stream and tributaries the triangle floater Alasmidonta undulata) creek heelsplitter Lasmigona compressa) and squawfoot Strophitus undulatus) Based on a review of the literature the triangle floater can tolerate a variety of conditions including the still waters behind dams The squawfoot is uncommon and is generally a river species and the heelsplitter prefers small to medium sized rivers with fine sand or gravel substrate Normandeaus review of the urmamed stream did not specifically focus on these species but based on the current investigation the uimamed stream may provide suitable habitat for the triangle floater and the heelsplitter Further studies would have to be conducted to confirmdeny the presence of these species

50 REGULATORY OVERVIEW

The State of Vermont regulates wetiand impacts based on the wetland class as determined by the Vermont Wetland Rules The US Army Corps of Engineers (Corps) has jurisdiction over impacts to the wetiands and streams within the project area under Section 404 of the Clean Water Act However under Superfund permit equivalency the proposed work need only comply with criteria and regulations and not actaally be permitted (42 CFR 103 9621e-l)

The Vermont Wetland Rules classify wetiands into three categories Class One Two and Three The Vermont Water Resoiu-ces Board (WRB) determines Class One wetiands as exceptional or irreplaceable and merits the highest level of protection Class One wetiands must be designated by the WRB Class Two wetlands are presumed to serve one or more wetiand fimctions at a significant level The Vermont Significant Wetiand Inventory maps (VSWI) designate Class Two wetiands including most Palustrine wetlands and wetlands contiguous to mapped wetlanltis Class Three wetiands are not mapped on the VSWI maps and the WRB has not determined that these wetiands provide a significant wetiand function Class Three wetiands are not protected under the Vermont Wetiand Rules

The VSWI mapped two Class Two wetiands within the project area The wetiand north of Route 2 containing WESTON sediment sampling stations SD 25 26 28 29 (Figure 2) and a wetiand on Tributary 2 east of a commercial development access road crossing over the tributary (Figure 3) There are no Class One wetlands within the Town of Williston at this time (April Moulaert VT DEC Wetiands Ecologist personal communication June 2004) The remaining wetiands within the unnamed stream corridor are Class Three wetlands The VT DEC recommends a site review to confirm the classification of wetlands within a project area

The New England Division of the Corps has issued a Department of the Army General Permit for the State of Vermont which outiines an expedited permit process for activities with minimal wetland impacts Category A non-reportingminimal impact activities do not require a separate permit fi-om

the Corps for impacts under 3000 square feet (SF) provided that all restrictions and conditions of the General Permit are met and there are no impacts to special wetlands (fen bog and vernal pool) Category B screeningminimal impact activities include projects impacting over 3000 SF of wetiand An application is filed directly to the Corps for impacts from 5000 SF to 1 acre An individual permit fi-om the Corps is required for projects not meeting the General Permit standards

60 SUMMARY

Normandeau Associates conducted an assessment of wetland classes and threatened species habitat associated with an uimamed stream and portions of its two tributaries (Tributaries 2 and 3) in Williston Vermont for the Commerce Street Plume Project The unnamed stream channel was divided into 17 segments related to previously determined WESTON sediment sampling locations plus the immediate area of the two tributaries A total of 6697 linear feet of stream channel was reviewed and 12047 feet of wetland classified along both banks of the unnamed stream and portions of its two tributaries A habitat assessment was completed for two Vermont threatened species the eastem sand darter Ammocrypta pellucida) and eastem pearlshell mussel Margaritifera margaritifera) The assessment of the unnamed stream found no suitable habitat for these two Vermont threatened species

Threatened Species Habitat Assessment

A habitat assessment was conducted of the unnamed stream to identify potential suitable habitat for the Eastem Pearlshell (Margaritifera margaritifera) and the Eastem Sand Darter Ammocrypta pellucida) Both species are listed as threatened in the State of Vermont In order to minimize disturbance of the streambed substrate during observations the habitat assessment began at the downstream (southern) end of the unnamed stream corridor off South Brownell Road and continued upstream to approximately 750 feet north of Route 2 Where possible observations were made while walking in the streambed to best determine substrate type and depth Otherwise observations were made streamside A metal soil auger was used to probe the substrate to help determine sediment type and depth Notes were also made on flow rate water depth width of stream channel height of banks vegetation cover and suitability for the species of concem Habitat descriptions were recorded on field data sheets (Appendix B) For description purposes the stream was divided into segments corresponding with stream corridor GPS points and wetland identifications

GPS Location and Mapping

Normandeau located the start and end points of the wetlands and potential habitat for the eastern pearlshell and sand darter using a Trimblereg GPS luiit The GPS data were post processed to provide submeter accuracy A summary of the post processing data with a horizontal precision of 95 is provided in Appendix C Reference points were located for use in insertion onto the base map The base map was compiled using available information from the Vermont Center for Geographic Information sediment sampling stations provided by WESTON and Vermont Significant Wetland Inventory map data

30 FINDINGS

Wetlands

The wetlands bordering the unnamed stream corridor are in the Palustrine (fieshwater) system and the stream and wetlands within the channel are within the Riverine system The dominant wetland classes bordering the stream are Palustrine Emergent persistent (PEMl) and Palustrine Scmb Shrub broad-leaved deciduous (PSSl) with Palustrine Forested deciduous (PFOl) wetlands observed along the uplandwetland edge (Figures 2 3 and 4) The majority of the stream channel is classified as Riverine Lower Perennial Unconsolidated Shore sandmud (R2US23) A total of 6697 linear feet of stream channel was reviewed and 12047 feet of wetiand classified along the banks of the unnamed stream (Table 1)

Along the project corridor the wetlands bordering the unnamed stream are within the 100-year floodplain The wetland system is dynamic within the stream corridor as a result of fluctuating water levels related to a series of beaver dams several of which are shown on mapping compiled by WESTON (Appendix C) At the time of the field investigation all the dams had been breached allowing water levels to drop The upstream wetlands in the immediate area of the dams are currentiy dominated by emergent vegetation which would be expected to change to a mix of shrubs and emergent species if water levels are maintained at current levels

North of Route 2 the stream channel has been piped under an existing facility (Lot 8-105-22) The emergentshrub swamp north of the facility is approximately 300 feet wide Downstream of Route 2 the stream corridor has been impacted by development particularly fi-om Route 2 south to a point approximately 500 feet south of SDSW 18 (Lot 7-19-36) The stream channel has been ditched and the bordering wetlands range fiom 5 to 15 feet in width with the exception of an area aroimd a former beaver dam intiie vicinity of SDSW 30 (Lot 7-19-20)

Beginning at the confluence with Tributary 3 and extending downstream there have been fewer impacts to wetiands and the unnamed stream except at road crossings and along sections of the westem bank bordering the Commerce Street industrial park The stream channel is sinuous with well defined banks The bordering wetlands range from 20 to 200 feet in width and are primarily shrub swamp with emergent species in the understory and trees along the wetland edge There is a short segment of forested wetland downstream of Marshall Avenue The trees near the road and extending up Tributary 2 to a road crossing to a commercial development (the road and development were constructed after the date of the aerial photography (Figure 4)) have died back as a result of flooding due to a beaver dam which has since been breached

The dominant herbaceous species within the emergent wetiands along the uimamed stream include reed canary grass Phalaris arundinacea) jewelweed Impatiens capensis) purple loosestrife Lythrum salicaria) goldeiuod species Solidago spp) red top Agrostis alba) wool grass Scirpus cyperinus) shallow sedge Carex lurida) sedge species Carex spp) sensitive fem Onoclea sensibilis) soft msh Juncus effusus) and broad-leaved cattail Typha latifolia) The dominant shmb species within the shrub swamp along the unnamed stream include alder Alnus incana) arrowwood Vibemum dentatum) grey birch Betula populifolia) elderberry Sambucus canadensis) honeysuckle Lonicera spp) and alder-buckthom Frangula alnus) The dominant tree species within the forested wetland along the unnamed stream include red maple Acer rubrum) ehn Ulmus americana) green ash Fraxinus pensylvanica)

Threatened Species Habitat Assessment

Little suitable habitat was found for either the eastern pearlshell or the eastem sand darter within the unnamed stream An approximate 1500 foot section of the unnamed stream has gravel or cobble bottom which would be considered to have low potential as habitat for the eastem sand darter This area extendsfirom just north of SD 19 to SD 35 (Figure 2) The Vermont Department of Conservation (Richard Langdon Aquatic Biologist VT DEC personal communication June 2004) concurred with Normandeaus assessment that the unnamed stream (Vermont Tributary 4 of Muddy Brook) is an unlikely place for either eastem pearlshell or the eastem sand darter to occur

Streambed characteristics were similar along the entire length of the unnamed stream with some variations in width depth and vegetative cover The unnamed stream is perennial with a narrow chaimel 2 to 5-feet wide and soft substrate bottom Flow at the time of observation was moderate (lt 1 foot per second) except behind the numerous breached beaver dams where flow is much reduced The stream charmel is generally well defined with 1 to 2 foot high banks In some areas the banks are less than 1 foot high Near the Route 2 culvert the banks were over 6 feet high Silt over fine spounduid and mud was the dominant substrate type with the exception of the sectionfi-om SD19 to SD 35 which has more gravel and cobble substrate The following species were observed within the unnamed stream fi-eshwater clam species (Sphaeriidae spp) minnow (Pimephales spp) shiner Notemigonus spp) killifish Fundulus spp) and stickleback (family Gasterosteidae) The eastem

pearlshell is a fireshwater mussel that prefers firm sand gravel or cobble in a range of flow conditions including fast-flowing mountain streams (Nedeau et al 2000) as well as quiet locations next to mshing waters where it can burrow in an upright position (Martin 1997) The eastem pearlshell also requires sahnonid species as the host for the development of the glochidia or larval stage (Nadeau et al 2000 Martin 1997) Sahnonids require cool fast flowing gravel cobble bottom streams (Richard Simmons Fisheries Biologist Normandeau Associates personal communication June 2004) which are not present in the area of study

The eastem sand darter is afi-eshwaterfish restricted to moderate size streams and large warm water rivers with clean sandy bottoms that have currents slow enough to retain sand but fast enough to prevent the deposition of silt (httpfishdnrcomelledun-fishPercidaesanddarterhtml Richard Langdon Aquatic Biologist VT DEC personal commimication June 2004) According to the Vermont Department of Environmental Conservation (VT DEC) this fish is almost always found below the Fall Line (150-foot elevation) in Vermont Littie information is available for this species but it has been reported in the Lamiolle River fom miles fi-om Lake Champlain and from the Poultaey River on the border between Vermont and New York

Richard Langdon VT DEC Aqxiatic Biologist provided three additional Vermont mussel species of concem andor threatened species that maybe found within the unnamed stream and tributaries the triangle floater Alasmidonta undulata) creek heelsplitter Lasmigona compressa) and squawfoot Strophitus undulatus) Based on a review of the literature the triangle floater can tolerate a variety of conditions including the still waters behind dams The squawfoot is uncommon and is generally a river species and the heelsplitter prefers small to medium sized rivers with fine sand or gravel substrate Normandeaus review of the urmamed stream did not specifically focus on these species but based on the current investigation the uimamed stream may provide suitable habitat for the triangle floater and the heelsplitter Further studies would have to be conducted to confirmdeny the presence of these species

50 REGULATORY OVERVIEW

The State of Vermont regulates wetiand impacts based on the wetland class as determined by the Vermont Wetland Rules The US Army Corps of Engineers (Corps) has jurisdiction over impacts to the wetiands and streams within the project area under Section 404 of the Clean Water Act However under Superfund permit equivalency the proposed work need only comply with criteria and regulations and not actaally be permitted (42 CFR 103 9621e-l)

The Vermont Wetland Rules classify wetiands into three categories Class One Two and Three The Vermont Water Resoiu-ces Board (WRB) determines Class One wetiands as exceptional or irreplaceable and merits the highest level of protection Class One wetiands must be designated by the WRB Class Two wetlands are presumed to serve one or more wetiand fimctions at a significant level The Vermont Significant Wetiand Inventory maps (VSWI) designate Class Two wetiands including most Palustrine wetlands and wetlands contiguous to mapped wetlanltis Class Three wetiands are not mapped on the VSWI maps and the WRB has not determined that these wetiands provide a significant wetiand function Class Three wetiands are not protected under the Vermont Wetiand Rules

The VSWI mapped two Class Two wetiands within the project area The wetiand north of Route 2 containing WESTON sediment sampling stations SD 25 26 28 29 (Figure 2) and a wetiand on Tributary 2 east of a commercial development access road crossing over the tributary (Figure 3) There are no Class One wetlands within the Town of Williston at this time (April Moulaert VT DEC Wetiands Ecologist personal communication June 2004) The remaining wetiands within the unnamed stream corridor are Class Three wetlands The VT DEC recommends a site review to confirm the classification of wetlands within a project area

The New England Division of the Corps has issued a Department of the Army General Permit for the State of Vermont which outiines an expedited permit process for activities with minimal wetland impacts Category A non-reportingminimal impact activities do not require a separate permit fi-om

Commerce Street Plume Project

the Corps for impacts under 3000 square feet (SF) provided that all restrictions and conditions of the General Permit are met and there are no impacts to special wetlands (fen bog and vernal pool) Category B screeningminimal impact activities include projects impacting over 3000 SF of wetiand An application is filed directly to the Corps for impacts from 5000 SF to 1 acre An individual permit fi-om the Corps is required for projects not meeting the General Permit standards

60 SUMMARY

Normandeau Associates conducted an assessment of wetland classes and threatened species habitat associated with an uimamed stream and portions of its two tributaries (Tributaries 2 and 3) in Williston Vermont for the Commerce Street Plume Project The unnamed stream channel was divided into 17 segments related to previously determined WESTON sediment sampling locations plus the immediate area of the two tributaries A total of 6697 linear feet of stream channel was reviewed and 12047 feet of wetland classified along both banks of the unnamed stream and portions of its two tributaries A habitat assessment was completed for two Vermont threatened species the eastem sand darter Ammocrypta pellucida) and eastem pearlshell mussel Margaritifera margaritifera) The assessment of the unnamed stream found no suitable habitat for these two Vermont threatened species

North of Route 2 the stream channel has been piped under an existing facility (Lot 8-105-22) The emergentshrub swamp north of the facility is approximately 300 feet wide Downstream of Route 2 the stream corridor has been impacted by development particularly fi-om Route 2 south to a point approximately 500 feet south of SDSW 18 (Lot 7-19-36) The stream channel has been ditched and the bordering wetlands range fiom 5 to 15 feet in width with the exception of an area aroimd a former beaver dam intiie vicinity of SDSW 30 (Lot 7-19-20)

Beginning at the confluence with Tributary 3 and extending downstream there have been fewer impacts to wetiands and the unnamed stream except at road crossings and along sections of the westem bank bordering the Commerce Street industrial park The stream channel is sinuous with well defined banks The bordering wetlands range from 20 to 200 feet in width and are primarily shrub swamp with emergent species in the understory and trees along the wetland edge There is a short segment of forested wetland downstream of Marshall Avenue The trees near the road and extending up Tributary 2 to a road crossing to a commercial development (the road and development were constructed after the date of the aerial photography (Figure 4)) have died back as a result of flooding due to a beaver dam which has since been breached

The dominant herbaceous species within the emergent wetiands along the uimamed stream include reed canary grass Phalaris arundinacea) jewelweed Impatiens capensis) purple loosestrife Lythrum salicaria) goldeiuod species Solidago spp) red top Agrostis alba) wool grass Scirpus cyperinus) shallow sedge Carex lurida) sedge species Carex spp) sensitive fem Onoclea sensibilis) soft msh Juncus effusus) and broad-leaved cattail Typha latifolia) The dominant shmb species within the shrub swamp along the unnamed stream include alder Alnus incana) arrowwood Vibemum dentatum) grey birch Betula populifolia) elderberry Sambucus canadensis) honeysuckle Lonicera spp) and alder-buckthom Frangula alnus) The dominant tree species within the forested wetland along the unnamed stream include red maple Acer rubrum) ehn Ulmus americana) green ash Fraxinus pensylvanica)

Threatened Species Habitat Assessment

Little suitable habitat was found for either the eastern pearlshell or the eastem sand darter within the unnamed stream An approximate 1500 foot section of the unnamed stream has gravel or cobble bottom which would be considered to have low potential as habitat for the eastem sand darter This area extendsfirom just north of SD 19 to SD 35 (Figure 2) The Vermont Department of Conservation (Richard Langdon Aquatic Biologist VT DEC personal communication June 2004) concurred with Normandeaus assessment that the unnamed stream (Vermont Tributary 4 of Muddy Brook) is an unlikely place for either eastem pearlshell or the eastem sand darter to occur

Streambed characteristics were similar along the entire length of the unnamed stream with some variations in width depth and vegetative cover The unnamed stream is perennial with a narrow chaimel 2 to 5-feet wide and soft substrate bottom Flow at the time of observation was moderate (lt 1 foot per second) except behind the numerous breached beaver dams where flow is much reduced The stream charmel is generally well defined with 1 to 2 foot high banks In some areas the banks are less than 1 foot high Near the Route 2 culvert the banks were over 6 feet high Silt over fine spounduid and mud was the dominant substrate type with the exception of the sectionfi-om SD19 to SD 35 which has more gravel and cobble substrate The following species were observed within the unnamed stream fi-eshwater clam species (Sphaeriidae spp) minnow (Pimephales spp) shiner Notemigonus spp) killifish Fundulus spp) and stickleback (family Gasterosteidae) The eastem

pearlshell is a fireshwater mussel that prefers firm sand gravel or cobble in a range of flow conditions including fast-flowing mountain streams (Nedeau et al 2000) as well as quiet locations next to mshing waters where it can burrow in an upright position (Martin 1997) The eastem pearlshell also requires sahnonid species as the host for the development of the glochidia or larval stage (Nadeau et al 2000 Martin 1997) Sahnonids require cool fast flowing gravel cobble bottom streams (Richard Simmons Fisheries Biologist Normandeau Associates personal communication June 2004) which are not present in the area of study

The eastem sand darter is afi-eshwaterfish restricted to moderate size streams and large warm water rivers with clean sandy bottoms that have currents slow enough to retain sand but fast enough to prevent the deposition of silt (httpfishdnrcomelledun-fishPercidaesanddarterhtml Richard Langdon Aquatic Biologist VT DEC personal commimication June 2004) According to the Vermont Department of Environmental Conservation (VT DEC) this fish is almost always found below the Fall Line (150-foot elevation) in Vermont Littie information is available for this species but it has been reported in the Lamiolle River fom miles fi-om Lake Champlain and from the Poultaey River on the border between Vermont and New York

40 AGENCY COMMENTS

Richard Langdon VT DEC Aqxiatic Biologist provided three additional Vermont mussel species of concem andor threatened species that maybe found within the unnamed stream and tributaries the triangle floater Alasmidonta undulata) creek heelsplitter Lasmigona compressa) and squawfoot Strophitus undulatus) Based on a review of the literature the triangle floater can tolerate a variety of conditions including the still waters behind dams The squawfoot is uncommon and is generally a river species and the heelsplitter prefers small to medium sized rivers with fine sand or gravel substrate Normandeaus review of the urmamed stream did not specifically focus on these species but based on the current investigation the uimamed stream may provide suitable habitat for the triangle floater and the heelsplitter Further studies would have to be conducted to confirmdeny the presence of these species

50 REGULATORY OVERVIEW

The State of Vermont regulates wetiand impacts based on the wetland class as determined by the Vermont Wetland Rules The US Army Corps of Engineers (Corps) has jurisdiction over impacts to the wetiands and streams within the project area under Section 404 of the Clean Water Act However under Superfund permit equivalency the proposed work need only comply with criteria and regulations and not actaally be permitted (42 CFR 103 9621e-l)

The Vermont Wetland Rules classify wetiands into three categories Class One Two and Three The Vermont Water Resoiu-ces Board (WRB) determines Class One wetiands as exceptional or irreplaceable and merits the highest level of protection Class One wetiands must be designated by the WRB Class Two wetlands are presumed to serve one or more wetiand fimctions at a significant level The Vermont Significant Wetiand Inventory maps (VSWI) designate Class Two wetiands including most Palustrine wetlands and wetlands contiguous to mapped wetlanltis Class Three wetiands are not mapped on the VSWI maps and the WRB has not determined that these wetiands provide a significant wetiand function Class Three wetiands are not protected under the Vermont Wetiand Rules

The VSWI mapped two Class Two wetiands within the project area The wetiand north of Route 2 containing WESTON sediment sampling stations SD 25 26 28 29 (Figure 2) and a wetiand on Tributary 2 east of a commercial development access road crossing over the tributary (Figure 3) There are no Class One wetlands within the Town of Williston at this time (April Moulaert VT DEC Wetiands Ecologist personal communication June 2004) The remaining wetiands within the unnamed stream corridor are Class Three wetlands The VT DEC recommends a site review to confirm the classification of wetlands within a project area

The New England Division of the Corps has issued a Department of the Army General Permit for the State of Vermont which outiines an expedited permit process for activities with minimal wetland impacts Category A non-reportingminimal impact activities do not require a separate permit fi-om

the Corps for impacts under 3000 square feet (SF) provided that all restrictions and conditions of the General Permit are met and there are no impacts to special wetlands (fen bog and vernal pool) Category B screeningminimal impact activities include projects impacting over 3000 SF of wetiand An application is filed directly to the Corps for impacts from 5000 SF to 1 acre An individual permit fi-om the Corps is required for projects not meeting the General Permit standards

60 SUMMARY

Normandeau Associates conducted an assessment of wetland classes and threatened species habitat associated with an uimamed stream and portions of its two tributaries (Tributaries 2 and 3) in Williston Vermont for the Commerce Street Plume Project The unnamed stream channel was divided into 17 segments related to previously determined WESTON sediment sampling locations plus the immediate area of the two tributaries A total of 6697 linear feet of stream channel was reviewed and 12047 feet of wetland classified along both banks of the unnamed stream and portions of its two tributaries A habitat assessment was completed for two Vermont threatened species the eastem sand darter Ammocrypta pellucida) and eastem pearlshell mussel Margaritifera margaritifera) The assessment of the unnamed stream found no suitable habitat for these two Vermont threatened species

pearlshell is a fireshwater mussel that prefers firm sand gravel or cobble in a range of flow conditions including fast-flowing mountain streams (Nedeau et al 2000) as well as quiet locations next to mshing waters where it can burrow in an upright position (Martin 1997) The eastem pearlshell also requires sahnonid species as the host for the development of the glochidia or larval stage (Nadeau et al 2000 Martin 1997) Sahnonids require cool fast flowing gravel cobble bottom streams (Richard Simmons Fisheries Biologist Normandeau Associates personal communication June 2004) which are not present in the area of study

The eastem sand darter is afi-eshwaterfish restricted to moderate size streams and large warm water rivers with clean sandy bottoms that have currents slow enough to retain sand but fast enough to prevent the deposition of silt (httpfishdnrcomelledun-fishPercidaesanddarterhtml Richard Langdon Aquatic Biologist VT DEC personal commimication June 2004) According to the Vermont Department of Environmental Conservation (VT DEC) this fish is almost always found below the Fall Line (150-foot elevation) in Vermont Littie information is available for this species but it has been reported in the Lamiolle River fom miles fi-om Lake Champlain and from the Poultaey River on the border between Vermont and New York

40 AGENCY COMMENTS

Richard Langdon VT DEC Aqxiatic Biologist provided three additional Vermont mussel species of concem andor threatened species that maybe found within the unnamed stream and tributaries the triangle floater Alasmidonta undulata) creek heelsplitter Lasmigona compressa) and squawfoot Strophitus undulatus) Based on a review of the literature the triangle floater can tolerate a variety of conditions including the still waters behind dams The squawfoot is uncommon and is generally a river species and the heelsplitter prefers small to medium sized rivers with fine sand or gravel substrate Normandeaus review of the urmamed stream did not specifically focus on these species but based on the current investigation the uimamed stream may provide suitable habitat for the triangle floater and the heelsplitter Further studies would have to be conducted to confirmdeny the presence of these species

50 REGULATORY OVERVIEW

The State of Vermont regulates wetiand impacts based on the wetland class as determined by the Vermont Wetland Rules The US Army Corps of Engineers (Corps) has jurisdiction over impacts to the wetiands and streams within the project area under Section 404 of the Clean Water Act However under Superfund permit equivalency the proposed work need only comply with criteria and regulations and not actaally be permitted (42 CFR 103 9621e-l)

The Vermont Wetland Rules classify wetiands into three categories Class One Two and Three The Vermont Water Resoiu-ces Board (WRB) determines Class One wetiands as exceptional or irreplaceable and merits the highest level of protection Class One wetiands must be designated by the WRB Class Two wetlands are presumed to serve one or more wetiand fimctions at a significant level The Vermont Significant Wetiand Inventory maps (VSWI) designate Class Two wetiands including most Palustrine wetlands and wetlands contiguous to mapped wetlanltis Class Three wetiands are not mapped on the VSWI maps and the WRB has not determined that these wetiands provide a significant wetiand function Class Three wetiands are not protected under the Vermont Wetiand Rules

The VSWI mapped two Class Two wetiands within the project area The wetiand north of Route 2 containing WESTON sediment sampling stations SD 25 26 28 29 (Figure 2) and a wetiand on Tributary 2 east of a commercial development access road crossing over the tributary (Figure 3) There are no Class One wetlands within the Town of Williston at this time (April Moulaert VT DEC Wetiands Ecologist personal communication June 2004) The remaining wetiands within the unnamed stream corridor are Class Three wetlands The VT DEC recommends a site review to confirm the classification of wetlands within a project area

The New England Division of the Corps has issued a Department of the Army General Permit for the State of Vermont which outiines an expedited permit process for activities with minimal wetland impacts Category A non-reportingminimal impact activities do not require a separate permit fi-om

the Corps for impacts under 3000 square feet (SF) provided that all restrictions and conditions of the General Permit are met and there are no impacts to special wetlands (fen bog and vernal pool) Category B screeningminimal impact activities include projects impacting over 3000 SF of wetiand An application is filed directly to the Corps for impacts from 5000 SF to 1 acre An individual permit fi-om the Corps is required for projects not meeting the General Permit standards

60 SUMMARY

Normandeau Associates conducted an assessment of wetland classes and threatened species habitat associated with an uimamed stream and portions of its two tributaries (Tributaries 2 and 3) in Williston Vermont for the Commerce Street Plume Project The unnamed stream channel was divided into 17 segments related to previously determined WESTON sediment sampling locations plus the immediate area of the two tributaries A total of 6697 linear feet of stream channel was reviewed and 12047 feet of wetland classified along both banks of the unnamed stream and portions of its two tributaries A habitat assessment was completed for two Vermont threatened species the eastem sand darter Ammocrypta pellucida) and eastem pearlshell mussel Margaritifera margaritifera) The assessment of the unnamed stream found no suitable habitat for these two Vermont threatened species

Richard Langdon VT DEC Aqxiatic Biologist provided three additional Vermont mussel species of concem andor threatened species that maybe found within the unnamed stream and tributaries the triangle floater Alasmidonta undulata) creek heelsplitter Lasmigona compressa) and squawfoot Strophitus undulatus) Based on a review of the literature the triangle floater can tolerate a variety of conditions including the still waters behind dams The squawfoot is uncommon and is generally a river species and the heelsplitter prefers small to medium sized rivers with fine sand or gravel substrate Normandeaus review of the urmamed stream did not specifically focus on these species but based on the current investigation the uimamed stream may provide suitable habitat for the triangle floater and the heelsplitter Further studies would have to be conducted to confirmdeny the presence of these species

50 REGULATORY OVERVIEW

The State of Vermont regulates wetiand impacts based on the wetland class as determined by the Vermont Wetland Rules The US Army Corps of Engineers (Corps) has jurisdiction over impacts to the wetiands and streams within the project area under Section 404 of the Clean Water Act However under Superfund permit equivalency the proposed work need only comply with criteria and regulations and not actaally be permitted (42 CFR 103 9621e-l)

The Vermont Wetland Rules classify wetiands into three categories Class One Two and Three The Vermont Water Resoiu-ces Board (WRB) determines Class One wetiands as exceptional or irreplaceable and merits the highest level of protection Class One wetiands must be designated by the WRB Class Two wetlands are presumed to serve one or more wetiand fimctions at a significant level The Vermont Significant Wetiand Inventory maps (VSWI) designate Class Two wetiands including most Palustrine wetlands and wetlands contiguous to mapped wetlanltis Class Three wetiands are not mapped on the VSWI maps and the WRB has not determined that these wetiands provide a significant wetiand function Class Three wetiands are not protected under the Vermont Wetiand Rules

The VSWI mapped two Class Two wetiands within the project area The wetiand north of Route 2 containing WESTON sediment sampling stations SD 25 26 28 29 (Figure 2) and a wetiand on Tributary 2 east of a commercial development access road crossing over the tributary (Figure 3) There are no Class One wetlands within the Town of Williston at this time (April Moulaert VT DEC Wetiands Ecologist personal communication June 2004) The remaining wetiands within the unnamed stream corridor are Class Three wetlands The VT DEC recommends a site review to confirm the classification of wetlands within a project area

The New England Division of the Corps has issued a Department of the Army General Permit for the State of Vermont which outiines an expedited permit process for activities with minimal wetland impacts Category A non-reportingminimal impact activities do not require a separate permit fi-om

000014 2oi37rpto70204 10 Normandeau Assoclates Inc

Commerce Street Plume Project

the Corps for impacts under 3000 square feet (SF) provided that all restrictions and conditions of the General Permit are met and there are no impacts to special wetlands (fen bog and vernal pool) Category B screeningminimal impact activities include projects impacting over 3000 SF of wetiand An application is filed directly to the Corps for impacts from 5000 SF to 1 acre An individual permit fi-om the Corps is required for projects not meeting the General Permit standards

60 SUMMARY

Normandeau Associates conducted an assessment of wetland classes and threatened species habitat associated with an uimamed stream and portions of its two tributaries (Tributaries 2 and 3) in Williston Vermont for the Commerce Street Plume Project The unnamed stream channel was divided into 17 segments related to previously determined WESTON sediment sampling locations plus the immediate area of the two tributaries A total of 6697 linear feet of stream channel was reviewed and 12047 feet of wetland classified along both banks of the unnamed stream and portions of its two tributaries A habitat assessment was completed for two Vermont threatened species the eastem sand darter Ammocrypta pellucida) and eastem pearlshell mussel Margaritifera margaritifera) The assessment of the unnamed stream found no suitable habitat for these two Vermont threatened species

Richard Langdon VT DEC Aqxiatic Biologist provided three additional Vermont mussel species of concem andor threatened species that maybe found within the unnamed stream and tributaries the triangle floater Alasmidonta undulata) creek heelsplitter Lasmigona compressa) and squawfoot Strophitus undulatus) Based on a review of the literature the triangle floater can tolerate a variety of conditions including the still waters behind dams The squawfoot is uncommon and is generally a river species and the heelsplitter prefers small to medium sized rivers with fine sand or gravel substrate Normandeaus review of the urmamed stream did not specifically focus on these species but based on the current investigation the uimamed stream may provide suitable habitat for the triangle floater and the heelsplitter Further studies would have to be conducted to confirmdeny the presence of these species

50 REGULATORY OVERVIEW

The State of Vermont regulates wetiand impacts based on the wetland class as determined by the Vermont Wetland Rules The US Army Corps of Engineers (Corps) has jurisdiction over impacts to the wetiands and streams within the project area under Section 404 of the Clean Water Act However under Superfund permit equivalency the proposed work need only comply with criteria and regulations and not actaally be permitted (42 CFR 103 9621e-l)

The Vermont Wetland Rules classify wetiands into three categories Class One Two and Three The Vermont Water Resoiu-ces Board (WRB) determines Class One wetiands as exceptional or irreplaceable and merits the highest level of protection Class One wetiands must be designated by the WRB Class Two wetlands are presumed to serve one or more wetiand fimctions at a significant level The Vermont Significant Wetiand Inventory maps (VSWI) designate Class Two wetiands including most Palustrine wetlands and wetlands contiguous to mapped wetlanltis Class Three wetiands are not mapped on the VSWI maps and the WRB has not determined that these wetiands provide a significant wetiand function Class Three wetiands are not protected under the Vermont Wetiand Rules

The VSWI mapped two Class Two wetiands within the project area The wetiand north of Route 2 containing WESTON sediment sampling stations SD 25 26 28 29 (Figure 2) and a wetiand on Tributary 2 east of a commercial development access road crossing over the tributary (Figure 3) There are no Class One wetlands within the Town of Williston at this time (April Moulaert VT DEC Wetiands Ecologist personal communication June 2004) The remaining wetiands within the unnamed stream corridor are Class Three wetlands The VT DEC recommends a site review to confirm the classification of wetlands within a project area

The New England Division of the Corps has issued a Department of the Army General Permit for the State of Vermont which outiines an expedited permit process for activities with minimal wetland impacts Category A non-reportingminimal impact activities do not require a separate permit fi-om

the Corps for impacts under 3000 square feet (SF) provided that all restrictions and conditions of the General Permit are met and there are no impacts to special wetlands (fen bog and vernal pool) Category B screeningminimal impact activities include projects impacting over 3000 SF of wetiand An application is filed directly to the Corps for impacts from 5000 SF to 1 acre An individual permit fi-om the Corps is required for projects not meeting the General Permit standards

60 SUMMARY

Normandeau Associates conducted an assessment of wetland classes and threatened species habitat associated with an uimamed stream and portions of its two tributaries (Tributaries 2 and 3) in Williston Vermont for the Commerce Street Plume Project The unnamed stream channel was divided into 17 segments related to previously determined WESTON sediment sampling locations plus the immediate area of the two tributaries A total of 6697 linear feet of stream channel was reviewed and 12047 feet of wetland classified along both banks of the unnamed stream and portions of its two tributaries A habitat assessment was completed for two Vermont threatened species the eastem sand darter Ammocrypta pellucida) and eastem pearlshell mussel Margaritifera margaritifera) The assessment of the unnamed stream found no suitable habitat for these two Vermont threatened species

Richard Langdon VT DEC Aqxiatic Biologist provided three additional Vermont mussel species of concem andor threatened species that maybe found within the unnamed stream and tributaries the triangle floater Alasmidonta undulata) creek heelsplitter Lasmigona compressa) and squawfoot Strophitus undulatus) Based on a review of the literature the triangle floater can tolerate a variety of conditions including the still waters behind dams The squawfoot is uncommon and is generally a river species and the heelsplitter prefers small to medium sized rivers with fine sand or gravel substrate Normandeaus review of the urmamed stream did not specifically focus on these species but based on the current investigation the uimamed stream may provide suitable habitat for the triangle floater and the heelsplitter Further studies would have to be conducted to confirmdeny the presence of these species

50 REGULATORY OVERVIEW

The State of Vermont regulates wetiand impacts based on the wetland class as determined by the Vermont Wetland Rules The US Army Corps of Engineers (Corps) has jurisdiction over impacts to the wetiands and streams within the project area under Section 404 of the Clean Water Act However under Superfund permit equivalency the proposed work need only comply with criteria and regulations and not actaally be permitted (42 CFR 103 9621e-l)

The Vermont Wetland Rules classify wetiands into three categories Class One Two and Three The Vermont Water Resoiu-ces Board (WRB) determines Class One wetiands as exceptional or irreplaceable and merits the highest level of protection Class One wetiands must be designated by the WRB Class Two wetlands are presumed to serve one or more wetiand fimctions at a significant level The Vermont Significant Wetiand Inventory maps (VSWI) designate Class Two wetiands including most Palustrine wetlands and wetlands contiguous to mapped wetlanltis Class Three wetiands are not mapped on the VSWI maps and the WRB has not determined that these wetiands provide a significant wetiand function Class Three wetiands are not protected under the Vermont Wetiand Rules

The VSWI mapped two Class Two wetiands within the project area The wetiand north of Route 2 containing WESTON sediment sampling stations SD 25 26 28 29 (Figure 2) and a wetiand on Tributary 2 east of a commercial development access road crossing over the tributary (Figure 3) There are no Class One wetlands within the Town of Williston at this time (April Moulaert VT DEC Wetiands Ecologist personal communication June 2004) The remaining wetiands within the unnamed stream corridor are Class Three wetlands The VT DEC recommends a site review to confirm the classification of wetlands within a project area

The New England Division of the Corps has issued a Department of the Army General Permit for the State of Vermont which outiines an expedited permit process for activities with minimal wetland impacts Category A non-reportingminimal impact activities do not require a separate permit fi-om

000014 2oi37rpto70204 10 Normandeau Assoclates Inc

Commerce Street Plume Project

the Corps for impacts under 3000 square feet (SF) provided that all restrictions and conditions of the General Permit are met and there are no impacts to special wetlands (fen bog and vernal pool) Category B screeningminimal impact activities include projects impacting over 3000 SF of wetiand An application is filed directly to the Corps for impacts from 5000 SF to 1 acre An individual permit fi-om the Corps is required for projects not meeting the General Permit standards

60 SUMMARY

Normandeau Associates conducted an assessment of wetland classes and threatened species habitat associated with an uimamed stream and portions of its two tributaries (Tributaries 2 and 3) in Williston Vermont for the Commerce Street Plume Project The unnamed stream channel was divided into 17 segments related to previously determined WESTON sediment sampling locations plus the immediate area of the two tributaries A total of 6697 linear feet of stream channel was reviewed and 12047 feet of wetland classified along both banks of the unnamed stream and portions of its two tributaries A habitat assessment was completed for two Vermont threatened species the eastem sand darter Ammocrypta pellucida) and eastem pearlshell mussel Margaritifera margaritifera) The assessment of the unnamed stream found no suitable habitat for these two Vermont threatened species

40 AGENCY COMMENTS

Richard Langdon VT DEC Aqxiatic Biologist provided three additional Vermont mussel species of concem andor threatened species that maybe found within the unnamed stream and tributaries the triangle floater Alasmidonta undulata) creek heelsplitter Lasmigona compressa) and squawfoot Strophitus undulatus) Based on a review of the literature the triangle floater can tolerate a variety of conditions including the still waters behind dams The squawfoot is uncommon and is generally a river species and the heelsplitter prefers small to medium sized rivers with fine sand or gravel substrate Normandeaus review of the urmamed stream did not specifically focus on these species but based on the current investigation the uimamed stream may provide suitable habitat for the triangle floater and the heelsplitter Further studies would have to be conducted to confirmdeny the presence of these species

50 REGULATORY OVERVIEW

The State of Vermont regulates wetiand impacts based on the wetland class as determined by the Vermont Wetland Rules The US Army Corps of Engineers (Corps) has jurisdiction over impacts to the wetiands and streams within the project area under Section 404 of the Clean Water Act However under Superfund permit equivalency the proposed work need only comply with criteria and regulations and not actaally be permitted (42 CFR 103 9621e-l)

The Vermont Wetland Rules classify wetiands into three categories Class One Two and Three The Vermont Water Resoiu-ces Board (WRB) determines Class One wetiands as exceptional or irreplaceable and merits the highest level of protection Class One wetiands must be designated by the WRB Class Two wetlands are presumed to serve one or more wetiand fimctions at a significant level The Vermont Significant Wetiand Inventory maps (VSWI) designate Class Two wetiands including most Palustrine wetlands and wetlands contiguous to mapped wetlanltis Class Three wetiands are not mapped on the VSWI maps and the WRB has not determined that these wetiands provide a significant wetiand function Class Three wetiands are not protected under the Vermont Wetiand Rules

The VSWI mapped two Class Two wetiands within the project area The wetiand north of Route 2 containing WESTON sediment sampling stations SD 25 26 28 29 (Figure 2) and a wetiand on Tributary 2 east of a commercial development access road crossing over the tributary (Figure 3) There are no Class One wetlands within the Town of Williston at this time (April Moulaert VT DEC Wetiands Ecologist personal communication June 2004) The remaining wetiands within the unnamed stream corridor are Class Three wetlands The VT DEC recommends a site review to confirm the classification of wetlands within a project area

The New England Division of the Corps has issued a Department of the Army General Permit for the State of Vermont which outiines an expedited permit process for activities with minimal wetland impacts Category A non-reportingminimal impact activities do not require a separate permit fi-om

the Corps for impacts under 3000 square feet (SF) provided that all restrictions and conditions of the General Permit are met and there are no impacts to special wetlands (fen bog and vernal pool) Category B screeningminimal impact activities include projects impacting over 3000 SF of wetiand An application is filed directly to the Corps for impacts from 5000 SF to 1 acre An individual permit fi-om the Corps is required for projects not meeting the General Permit standards

60 SUMMARY

Normandeau Associates conducted an assessment of wetland classes and threatened species habitat associated with an uimamed stream and portions of its two tributaries (Tributaries 2 and 3) in Williston Vermont for the Commerce Street Plume Project The unnamed stream channel was divided into 17 segments related to previously determined WESTON sediment sampling locations plus the immediate area of the two tributaries A total of 6697 linear feet of stream channel was reviewed and 12047 feet of wetland classified along both banks of the unnamed stream and portions of its two tributaries A habitat assessment was completed for two Vermont threatened species the eastem sand darter Ammocrypta pellucida) and eastem pearlshell mussel Margaritifera margaritifera) The assessment of the unnamed stream found no suitable habitat for these two Vermont threatened species

Richard Langdon VT DEC Aqxiatic Biologist provided three additional Vermont mussel species of concem andor threatened species that maybe found within the unnamed stream and tributaries the triangle floater Alasmidonta undulata) creek heelsplitter Lasmigona compressa) and squawfoot Strophitus undulatus) Based on a review of the literature the triangle floater can tolerate a variety of conditions including the still waters behind dams The squawfoot is uncommon and is generally a river species and the heelsplitter prefers small to medium sized rivers with fine sand or gravel substrate Normandeaus review of the urmamed stream did not specifically focus on these species but based on the current investigation the uimamed stream may provide suitable habitat for the triangle floater and the heelsplitter Further studies would have to be conducted to confirmdeny the presence of these species

50 REGULATORY OVERVIEW

The State of Vermont regulates wetiand impacts based on the wetland class as determined by the Vermont Wetland Rules The US Army Corps of Engineers (Corps) has jurisdiction over impacts to the wetiands and streams within the project area under Section 404 of the Clean Water Act However under Superfund permit equivalency the proposed work need only comply with criteria and regulations and not actaally be permitted (42 CFR 103 9621e-l)

The Vermont Wetland Rules classify wetiands into three categories Class One Two and Three The Vermont Water Resoiu-ces Board (WRB) determines Class One wetiands as exceptional or irreplaceable and merits the highest level of protection Class One wetiands must be designated by the WRB Class Two wetlands are presumed to serve one or more wetiand fimctions at a significant level The Vermont Significant Wetiand Inventory maps (VSWI) designate Class Two wetiands including most Palustrine wetlands and wetlands contiguous to mapped wetlanltis Class Three wetiands are not mapped on the VSWI maps and the WRB has not determined that these wetiands provide a significant wetiand function Class Three wetiands are not protected under the Vermont Wetiand Rules

The VSWI mapped two Class Two wetiands within the project area The wetiand north of Route 2 containing WESTON sediment sampling stations SD 25 26 28 29 (Figure 2) and a wetiand on Tributary 2 east of a commercial development access road crossing over the tributary (Figure 3) There are no Class One wetlands within the Town of Williston at this time (April Moulaert VT DEC Wetiands Ecologist personal communication June 2004) The remaining wetiands within the unnamed stream corridor are Class Three wetlands The VT DEC recommends a site review to confirm the classification of wetlands within a project area

The New England Division of the Corps has issued a Department of the Army General Permit for the State of Vermont which outiines an expedited permit process for activities with minimal wetland impacts Category A non-reportingminimal impact activities do not require a separate permit fi-om

000014 2oi37rpto70204 10 Normandeau Assoclates Inc

Commerce Street Plume Project

the Corps for impacts under 3000 square feet (SF) provided that all restrictions and conditions of the General Permit are met and there are no impacts to special wetlands (fen bog and vernal pool) Category B screeningminimal impact activities include projects impacting over 3000 SF of wetiand An application is filed directly to the Corps for impacts from 5000 SF to 1 acre An individual permit fi-om the Corps is required for projects not meeting the General Permit standards

60 SUMMARY

Normandeau Associates conducted an assessment of wetland classes and threatened species habitat associated with an uimamed stream and portions of its two tributaries (Tributaries 2 and 3) in Williston Vermont for the Commerce Street Plume Project The unnamed stream channel was divided into 17 segments related to previously determined WESTON sediment sampling locations plus the immediate area of the two tributaries A total of 6697 linear feet of stream channel was reviewed and 12047 feet of wetland classified along both banks of the unnamed stream and portions of its two tributaries A habitat assessment was completed for two Vermont threatened species the eastem sand darter Ammocrypta pellucida) and eastem pearlshell mussel Margaritifera margaritifera) The assessment of the unnamed stream found no suitable habitat for these two Vermont threatened species

the Corps for impacts under 3000 square feet (SF) provided that all restrictions and conditions of the General Permit are met and there are no impacts to special wetlands (fen bog and vernal pool) Category B screeningminimal impact activities include projects impacting over 3000 SF of wetiand An application is filed directly to the Corps for impacts from 5000 SF to 1 acre An individual permit fi-om the Corps is required for projects not meeting the General Permit standards

60 SUMMARY

Normandeau Associates conducted an assessment of wetland classes and threatened species habitat associated with an uimamed stream and portions of its two tributaries (Tributaries 2 and 3) in Williston Vermont for the Commerce Street Plume Project The unnamed stream channel was divided into 17 segments related to previously determined WESTON sediment sampling locations plus the immediate area of the two tributaries A total of 6697 linear feet of stream channel was reviewed and 12047 feet of wetland classified along both banks of the unnamed stream and portions of its two tributaries A habitat assessment was completed for two Vermont threatened species the eastem sand darter Ammocrypta pellucida) and eastem pearlshell mussel Margaritifera margaritifera) The assessment of the unnamed stream found no suitable habitat for these two Vermont threatened species
