EXECUTIVE SUMMARY

The Remedial Investigation Report (RIR) provides sufficient information for establishment of

remedial action objectives, evaluation of remedial action alternatives, and selection of a remedy

pursuant to RCNY§ 43-1407(f). The remedial investigation (RI) described in this document is

consistent with applicable guidance.

Site Location and Current Usage

The Site is located at 390 and 400 Park Avenue South in the Gramercy section in Manhattan,

New York and is identified as Block 857 and Lots 40 and 46 on the New York City Tax Map.

Figure 1 shows the Site location. The Site is 19,275-square feet and is bounded by bounded to

the north and south by East 28th and East 27th Streets, respectively, followed by commercial

and residential dwellings to the north and a commercial building to the south. The property to

the west of Lot 40 is also a commercial building. Park Avenue South is located east of the

subject property followed by commercial and residential buildings. A map of the site boundary

is shown in Figure 2. Currently, the Site is vacant land.

Summary of Proposed Redevelopment Plan

The proposed future use of the Site will consist of a 475-foot tall 40-story mixed use

commercial/residential building with one cellar and one sub-cellar level. The proposed site

development will consist of commercial space on the first floor and residential dwellings on

floors two through forty. The cellar and sub-cellar level will occupy approximately 62,615 sf.

The first floor commercial retail space will occupy approximately 5,897 square-feet (sf). The

residential portion of the building will occupy approximately 407,436 sf (362 residential units).

The sub-cellar level will be occupied by mechanical rooms. The cellar will be occupied by

mechanical rooms, a pool, and amenities for building occupants. The cellar level of the building

will be built out to the extents of the subject property and will require the removal of soils on

the full footprint of the site to a depth of approximately 17-feet below ground surface (b.g.s.).

The sub-cellar will occupy approximately 13,250 sf of the 19,275 sf site. An area of soil

beneath the cellar level will remain along the southern and eastern neighboring properties. The

ground floor will not occupy the entire lot; however, the required courtyard area will be located

above the cellar level and will be paved with an impervious layer. Layout of the proposed site

development is presented in Appendix E.

Site excavation activities will be completed to the bedrock interface for the portion of the site

that will be occupied by the sub-cellar on Lot 46 which was encountered between 22 and

30-feet b.g.s. Competent bedrock was encountered beneath the proposed excavation extents

on Lot 40; therefore a layer of highly decomposed bedrock will remain in place beneath the

6

LANGAN

area that will be occupied by the sub-cellar. Based on the proposed excavation to allow for

construction of the building foundation on-site, it is estimated that approximately 28,060-tons of

soil (including all fill material) will be removed from the site.

The current zoning designation is commercial district C5-3, which is a central commercial

district with continuous retail frontage intended for offices and retail establishments

Specifically, the C5 zoning indicates that the site is zoned for retail and service uses and may be

developed with a tower. The proposed use is consistent with existing zoning for the property.

Summary of Past Uses of Site and Areas of Concern

Based on Sanborn map review and information provided regarding previous ownership of the

site, historic use of the site included commercial and residential buildings. Lot 40 of the site

was developed with the former 8-story office building that was identified as having been

constructed in 1911. Prior to the construction of the office building Lot 40 was shown as four

individual lots that were occupied with two four-story mixed-use commercial/residential

buildings with basements on the southern portion and two four-story commercial buildings with

basements that are identified as being used as a delivery service on the northern portion of the

lot.

Lot 46 was shown as being developed as an at grade parking lot on the 1968 Sanborn map.

The 1890 and 1899 Sanborn maps show Lot 46 as being occupied by eight individual lots that

were used for mixed use commercial/residential purposes. Lot 46 is shown as being

consolidated into four individual lots, one of which is occupied by a hotel and the remaining are

occupied by mixed use commercial/residential buildings.

Based on information maintained online by the New York City Department of Finance

(NYCDOF) the following provides past ownership information as identified in Langan’s 12

September 2011 Phase I ESA:

Block 857 Lot 40

Title records were reviewed from 2002 until present. The current owner is identified as 400

Park Avenue South, LLC. The subject property was previously owned by The New York Life

Insurance Company until June 2002 when it was sold to 390 Park Avenue South, LLC which

owned the property until February 2005 when the current owner purchased the property.

7

LANGAN

Block 857 Lot 46

Title records were reviewed from 2004 until present. The current owner is identified as 400

Park Avenue South, LLC, no further information was provided regarding previous ownership of

the property.

The following is a list of the AOCs investigated as part of the Remedial Investigation:

1. Horizontal Steam Boilers associated with Lot 46;

2. Onsite Historic Fill; and,

3. Surrounding Sites – Potential onsite migration of offsite contaminants.

Summary of the Work Performed under the Remedial Investigation

ET 400 PAS, LLC performed the following scope of work:

1. Conducted a Site inspection to identify AOCs and physical obstructions (i.e. structures,

buildings, etc.);

2. Completed a geophysical survey of the former parking lot area to determine if any sub-

surface anomalies existed;

3. Installed nine soil borings across the entire project Site, and collected twenty-three soil

samples for chemical analysis from the soil borings to evaluate soil quality;

4. Installed three groundwater monitoring wells throughout the Site to establish

groundwater flow direction and collected three groundwater samples for chemical

analysis to evaluate groundwater quality;

5. Installed four soil vapor probes around Site perimeter and collected four samples for

chemical analysis.

Summary of Environmental Findings

1. Elevation of the property ranges from approximately 34.25 to 34.75-feet above mean

sea level (amsl).

2. Depth to groundwater ranges from 17.23 to 21.09-feet amsl below ground surface

(b.g.s.) at the Site.

3. Groundwater flow direction is generally from west to east beneath the Site.

8

LANGAN

4. Depth to bedrock is approximately 9.75 to 7-feet amsl at the Site.

5. The stratigraphy of the site, from the surface down on Lot 46 consists of approximately

5 to 13-feet of fill material underlain by 14 to 23-feet of native silt followed by mica

schist bedrock. The stratigraphy of Lot 40, from the surface down consists of

demolition debris which is placed on the former 8-story office building slab which occurs

approximately 12-feet below current site grades. The existing building slab is underlain

by a thin layer (less than 4-feet) of fill material, which is underlain by approximately

8-feet of native silt, which according to the geotechnical report for the site is underlain

by a significant layer of dense decomposed bedrock, followed by mica schist bedrock.

6. The soil analytical results of this Remedial Investigation showed no VOCs above

Track 1 unrestricted use SCOs (Track 1 SCOs). Seven SVOCs exceeding Track 2

Restricted Residential SCOs in three samples. All of these compounds were PAH

and concentrations were consistent with findings of historical fill during soil

sampling. Three pesticides were detected above Track 1 in three samples but did

not exceed Track 2 Restricted Residential SCOs. Similarly, PCBs were detected in

two samples above Track 1 but did not exceed Track 2 Restricted Residential

SCOs. The metals mercury, nickel and zinc exceeded Track 1 SCOs in between

one and 6 samples but did not exceed Track 2 Restricted Residential SCOs.

Barium, cadmium and copper exceeded Track 2 Restricted Residential SCOs in

only one sample each. Lead exceeded Track 2 Restricted Residential SCOs in only

two soil samples. Overall, the soil findings were unremarkable and did not indicate

any evidence of an onsite contaminant source. Low level contamination that was

observed can be explained by the presence of historical fill.This layer of fill material

was observed throughout Lot 46 from approximately 5 to 13-feet below current grades

and contained varying quantities of sand, brick, concrete, gravel and silt, and was

underlain by a native silt layer.

7. The groundwater analytical results showed no exceedances to NYSDEC Part 703

Groundwater Quality Standards (GWQS) for SVOCs, pesticides or PCBs. VOCs were

detected in exceedance of the NYSDEC Part 703 Groundwater Quality Standards in the

upgradient well MW-1 for 1,2-cis dichloroethene (DCE), tetrachloroethene (PCE), and

trichloroethene (TCE) Acetone and chloroform were detected at low concentrations in

the MW-2 sample. No other VOC exceedances were reported.

Dissolved metals in groundwater included sodium, manganese and silver above GWQS.

Sodium and manganese are attributed to background water quality influences and silver

was only marginally above the standard in one sample. No other metals exceedences of

9

LANGAN

the NYSDEC Part 703 Groundwater Quality Standards were reported in for dissolved

groundwater samples collected at the site.

8. The soil vapor analytical results for this Remedial Investigation showed very low levels

of PCE and well below the sub-slab guidance value to initiate monitoring (all results

were below 8 ug/m3 compared to the monitor level of 100 ug/m3). TCE was not

detected in four soil vapor samples. Low levels of xylenes and acetone were detected

in most soil vapor samples. One very low level of chloroform (less than 7 ug/m3) was

detected in one of four samples. No VOCs were detected in soil samples from the site

above Track 1 SCOs. Several chlorinated hydrocarbons were detected in an upgradient

groundwater sample and suggest an offsite source for these compounds to the west of

the property.

1.0 SITE BACKGROUND

ET 400 PAS, LLC has enrolled in the New York City Brownfield Cleanup Program

(NYC BCP) to investigate and remediate a 0.44-acre site located at 390 and 400 Park

Avenue South in the Gramercy section of Manhattan, New York. Mixed commercial

residential use is proposed for the property. The RI work was performed between

17 and 18 October 2011 and 27 and 28 October 2011. This RIR summarizes the nature

and extent of contamination and provides sufficient information for establishment of

remedial action objectives, evaluation of remedial action alternatives, and selection of a

remedy that is protective of human health and the environment consistent with the use

of the property pursuant to RCNY§ 43-1407(f).

1.1 Site Location and Current Usage

The Site is located at 390 and 400 Park Avenue South in the Gramercy section in

Manhattan, New York and is identified as Block 857 and Lots 40 and 46 on the

New York City Tax Map. Figure 1 shows the Site location. The Site is

19,275-square feet and is bounded to the north and south by East 28th and

East 27th Streets, respectively, followed by mixed-use commercial/ residential

buildings to the north and a commercial building to the south. The property to

the west of Lot 40 is also a commercial building. Park Avenue South is located

east of the subject property followed by mixed-use commercial/residential

buildings. A map of the site boundary is shown in Figure 2. Currently, the Site is

vacant land. An 8-story building was recently demolished on Lot 40 in the Fall of

2011.

1.2 Proposed Redevelopment Plan

The proposed future use of the Site will consist of a 475-foot tall 40-story mixed

use commercial/residential building with one cellar and one sub-cellar level. The

proposed site development will consist of commercial space on the first floor

and residential dwellings on floors two through forty. The cellar and sub-cellar

level will occupy approximately 62,615 sf. The first floor commercial retail space

will occupy approximately 5,897 square-feet (sf). The residential portion of the

building will occupy approximately 407,436 sf (362 residential units). The sub-

cellar level will be occupied by mechanical rooms. The cellar will be occupied by

mechanical rooms, a pool, and amenities for building occupants. The cellar level

of the building will be built out to the extents of the subject property and will

11

LANGAN

require the removal of soils on the full footprint of the site to a depth of

approximately 17-feet below ground surface (b.g.s.). The sub-cellar will occupy

approximately 13,250 sf of the 19,275 sf site. An area of soil beneath the cellar

level will remain along the southern and eastern neighboring properties. The

ground floor will not occupy the entire lot; however, the required courtyard area

will be located above the cellar level and will be paved with an impervious layer.

Layout of the proposed site development is presented in Appendix E.

Site excavation activities will be completed to the bedrock interface for the

portion of the site that will be occupied by the sub-cellar on Lot 46 which was

encountered between 22 and 30-feet b.g.s. Competent bedrock was

encountered beneath the proposed excavation extents on Lot 40; therefore a

layer of highly decomposed bedrock will remain in place beneath the area that

will be occupied by the sub-cellar. Based on the proposed excavation to allow

for construction of the building foundation on-site, it is estimated that

approximately 28,060-tons of soil (including all fill material) will be removed from

the site.

The current zoning designation is commercial district C5-3, which is a central

commercial district with continuous retail frontage intended for offices and retail

establishments Specifically, the C5 zoning indicates that the site is zoned for

retail and service uses and may be developed with a tower. The proposed use is

consistent with existing zoning for the property.

1.3 Description of Surrounding Property

The site is located within an area of dense mixed use commercial/residential

development in the Gramercy neighborhood of Manhattan. According to New

York City Planning Commission Zoning Map 8D dated 21 September 2011 the

subject property and adjoining property to the south and west are zoned C5-3,

the adjoining properties to the northwest are zoned C5-2, the adjoining

properties to the northeast and east are zoned C6-4A. The observed use of the

surrounding properties (commercial and mixed use commercial/residential) is

consistent with the current zoning designations.

According to the information maintained on-line by the New York City Office of

Environmental Remediation (NYCOER) Searchable Property Environmental

E-Database (SPEED [https://gis.nyc.gov/moer/speed/]) a day care center

identified as The Children’s Center of N.Y. Life at 51 Madison Avenue is located

approximately 105-feet to the south of the site. The next closest child care

12

LANGAN

facility is located approximately 800-feet to the northeast of the site. The closest

school is identified as the School for the Physical City at 55 East 25th Street,

located approximately 475-feet to the south of the site, and closest hospital is

identified as Bellevue Hospital Center, which is located approximately 0.5-miles

to the east of the site at 462 First Avenue.

Figure 3 shows the surrounding land usage.

2.0 SITE HISTORY

2.1 Past Uses and Ownership

Based on Sanborn map review and information provided regarding previous

ownership of the site, historic use of the site included commercial and

residential buildings. Lot 40 of the site was developed with an 8-story office

building with a basement that was identified as having been constructed in 1911

and was demolished in 2011. Prior to the construction of the office building

Lot 40 was shown in Sanborn maps as four individual lots that were occupied by

two four-story mixed-use commercial/residential buildings with basements on

the southern portion and two four-story commercial buildings with basements

that are identified as being used as a delivery service on the northern portion of

the lot.

Lot 46 was shown as being developed as an at grade parking lot on the 1968

Sanborn map and was operated as a parking lot until 2004. The 1890 and 1899

Sanborn maps show Lot 46 as being occupied by eight individual lots that were

used for mixed use commercial/residential purposes. Lot 46 is shown as being

consolidated into four individual lots, one of which is occupied by a hotel and the

remaining are occupied by mixed use commercial/residential buildings beginning

on the 1929 Sanborn map. Use of the property was consistent until the property

was re-developed as a parking lot.

Based on information maintained online by the New York City Department of

Finance (NYCDOF) the following provides past ownership information as

identified in Langan’s 12 September 2011 Phase I ESA:

13

LANGAN

Block 857 Lot 40

Title records were reviewed from 2002 until present. The current owner is

identified as ET 400 PAS, LLC. The site was owned by 400 Park Avenue South, LLC

from 2002 until December 2011. The subject property was previously owned by

The New York Life Insurance Company until June 2002 when it was sold to

390 Park Avenue South, LLC which owned the property until February 2005 when

the current owner purchased the property.

Block 857 Lot 46

Title records were reviewed from 2004 until present. The current owner is

identified as ET 400 PAS, LLC and was previously owned by 400 Park Avenue

South, LLC, no further information was provided regarding previous ownership

of the property.

2.2 Previous Investigations

The following previous environmental reports were completed for the subject

property:

Phase I Environmental Site Assessment (ESA) Report dated March 2002

prepared for Kalimian West 20th, LLC c/o Mr. Steve Shokouhi, Esq.,

prepared by C. A. Rich Consultants, Inc. of Plainview, New York.

Phase I Environmental Site Assessment (ESA) Report dated

12 September 2011 prepared for Equity Residential Management, LLC by

Langan.

Copies of the ESA reports are provided in Appendix B.

The C. A. Rich Consultants March 2002 ESA identified that the subject property

is comprised of two adjoining legal lots as identified by the New York City

Department of Finance as Block 857 Lots 40 and 46. Historic use of the site

included commercial and residential buildings including a hotel and the current

8-story building that is identified as having been constructed in 1911. The hotel

and other mixed use commercial residential properties are identified as being

replaced with the current parking lot on the 1968 Sanborn map. No Recognized

Environmental Conditions (RECs) were identified in the Phase I ESA report with

the exception of the presence of two horizontal steam boilers that were

14

LANGAN

identified in the former hotel building (northern portion of Lot 46) on the Sanborn

Maps.

A Phase I Environmental Site Assessment (ESA) was prepared by Langan

Engineering and Environmental Services, Inc. on behalf of Equity Residential

to identify current or potential environmental concerns and Recognized

Environmental Conditions (RECs) at the 0.44-acre proposed development site

consisting of the property at 390 and 400 Park Avenue South, (Block 857

Lots 40 and 46) located in New York, New York. The ESA included a site

inspection, review of historical information, completion of a federal/state/local

environmental database search, and interviews with local and state agencies

to assess current and past site conditions. The ESA was conducted in a

manner consistent with industry standard and practice and in accordance with

the Standards of the American Society for Testing and Materials (ASTM) E1527-

05 Standard Practice for Environmental Site Assessments.

The Langan September 2011 Phase I ESA identified no RECs; however, the

potential presence of undocumented historic heating-oil underground storage

tanks (USTs), the potential impacts from open spills from surrounding properties

and the potential presence of historic fill were identified as business

environmental risks.

2.3 Site Inspection

Langan completed an inspection of the site on 16 October 2011 for the purposes

of identifying any additional areas of concern that required investigation. The

following is a summary of the conditions observed during this inspection.

Lot 46

The site is occupied by an at grade parking lot that at the time of the Remedial

Investigation activities was being used for the staging of demolition equipment

and associated temporary construction trailers. A 500-gallon diesel above-

ground storage tank (AST) was stored at the site for the refueling of the

demolition equipment. The AST is contained within an awning that is

constructed of lumber and a temporary secondary containment system has been

constructed of lumber and plastic tarps. Minimal staining and absorbant material

was observed in the vicinity of the AST on the asphalt parking area. The asphalt

pavement in this area was observed to be in good condition. Other petroleum

15

LANGAN

substances were observed to be stored in flammable lockers and the area

surrounding the lockers was free of staining.

390 Park Avenue South, Lot 40

During Langan’s site inspection demolition of the building was observed to be

completed and only removal of subgrade foundations was ongoing. The building

basement was filled with demolition debris.

2.4 Areas of Concern

The AOCs identified for this site include:

1. Horizontal Steam Boilers;

2. Onsite Historic Fill; and,

3. Surrounding Sites – Potential onsite migration of offsite contaminants.

The scope of work for this Remedial Investigation was designed to:

1. Identify the potential presence and extent of impacted soil vapor, soil,

and/or groundwater at the site;

2. Determine contaminant(s) of concerns that may be encountered during

site redevelopment activities for incorporation into a construction Health

and Safety Plan, if necessary; and,

3. Evaluate remediation options for any impacted soil vapor, soil, and/or

groundwater in accordance with NYSDEC and NYCOER regulations, if

required.

The Phase I Reports generated for the site are presented in Appendix B. A map

showing areas of concern is presented in Figure 2.

3.2 Health and Safety

All work described in this RIR was performed in full compliance with applicable

laws and regulations, including Site and OSHA worker safety requirements and

HAZWOPER requirements and the site specific Health and Safety Plan.

3.3 Materials Management

All material encountered during the RI was managed in accordance with

applicable laws and regulations.

4.0 REMEDIAL INVESTIGATION ACTIVITIES

ET 400 PAS, LLC performed the following scope of work:

1. Conducted a Site inspection to identify AOCs and physical obstructions

(i.e., structures, buildings, etc.);

2. Completed a geophysical survey of the former parking lot area to determine if

the horizontal steam boilers or any other sub-surface anomalies existed;

3. Installed nine soil borings across the entire project Site, and collected twenty-

three soil samples for chemical analysis from the soil borings to evaluate soil

quality;

4. Installed three groundwater monitoring wells throughout the Site to establish

groundwater flow and collected three groundwater samples for chemical

analysis to evaluate groundwater quality;

5. Installed four soil vapor probes around Site perimeter and collected four samples

for chemical analysis.

4.1 Geophysical Investigation

Langan retained Naeva Geophysics, Inc. (Naeva) of Congers, New York to

complete a geophysical survey of the accessible areas of Lot 46. On

7 October 2011, Langan and Naeva completed an inspection of the site to

identify any areas of concern that should be evaluated. Based on the results of

the ground penetrating radar (GPR) survey, no subsurface anomalies indicative of

horizontal steam boilers or underground storage tanks were observed.

LANGAN

4.2 Borings and Monitoring Wells

Drilling and Soil Logging

Boring logs were prepared by a Langan geologist and are attached in

Appendix C. A map showing the location of soil borings and groundwater

monitoring wells is provided as Figure 4.

Lot 46

On 17 and 18 October 2011, six soil borings (ELB-1 through ELB-6) were

completed on Lot 46 (former parking lot area) in order to assess potential site-

wide fill conditions, the horizontal steam boilers and groundwater conditions.

The borings were completed by American Environmental Assessments

Corporation (AEA) of Wyandauch, New York using a track-mounted Geoprobe

7822DT Direct Push Drilling Rig. Borings were completed when refusal on

bedrock was encountered, which ranged from 20-30-feet below the current

grade at the site. Groundwater was generally observed to be 17 to 19-feet

below the current grade.

Continuous macrocore samples were collected to the bottom of each boring and

soil was classified and visually screened for evidence of contamination. No

evidence of petroleum contamination from the former horizontal boiler tanks or

off-site sources was observed.

Field screening of soil during sample collection for volatile organic compounds

(VOCs) using a photoionization detector (PID) was completed during the

installation of all six test borings. PID readings above background were

observed in ELB-1 that ranged from 0 ppm to 6.9 ppm. No other PID readings

above background were measured in any of the remaining borings.

Lot 40

On 27 and 28 October 2011, three soil borings (ELB-7 through ELB-9) were

completed in order to assess potential site-wide fill conditions and groundwater

conditions. The borings were completed by Warren George, Inc. of Jersey City,

New Jersey using a track-mounted Acker Soil XLS track mounted drilling rig from

15 to 21-feet below the current grade at the site. Borings were completed at

the interpreted depth to bedrock or refusal. Groundwater was generally

observed to be 20-feet below the current grade.

18

LANGAN

Continuous split-spoon samples were collected from beneath the former

building’s basement slab to the bottom of each boring. All soil samples were

classified and visually screened for evidence of contamination. No evidence of

contamination from the former horizontal boiler tanks or off-site sources was

observed.

Field screening of soil during sample collection for VOCs using a photo-ionization

detector PID was completed during the installation of all three test borings.

Elevated PID readings were not observed in any of the borings.

On 17 and 18 October 2011 (MW-1 and MW-3) and 28 October 2011 (MW-2),

groundwater monitoring wells were installed by a licensed well drillers, AEA and

Warren George, using 4-1/4-inch hollow stem augers and three-inch flush

threaded casing respectively. Each of the wells was installed to the completion

depth of the boring, which corresponded to the overburden-bedrock interface.

The wells were constructed with a screened interval across the groundwater

table. Each well was constructed with 10-feet of 2-inch diameter 0.010-inch slot

PVC well screen and the remainder of the well was constructed of 2-inch

diameter PVC Riser. The monitoring wells were finished with flush-mounted

protective casings in the former parking lot area and with a stick-up steel

protective casing in the former building area. On the same day that the wells

were installed, each well was developed by removing a total of five to ten well

volumes using a decontaminated submersible pump and surging techniques, or

until the groundwater was relatively free of silt.

Groundwater monitoring well locations are shown in Figure 4.

Survey

A site survey was completed by Langan on 8 November 2011 that identified the

locations and elevations of the monitoring wells that were installed as part of

this Remedial Investigation. The locations of the monitoring wells are shown on

Figure 4 and the elevations of the monitoring wells are shown on the contour

map provided as Figure 5.

Water Level Measurement

Groundwater levels were recorded prior to sampling with an oil/water interface

probe to determine the potential presence of light non-aqueous phase liquids

(LNAPL). No LNAPL or evidence of sheen was observed in any of the

monitoring wells.

Water level data is included in Table 2.

4.3 Sample Collection and Chemical Analysis

Sampling performed as part of the field investigation was conducted for all Areas

of Concern and also considered other means for bias of sampling based on

professional judgment, area history, discolored soil, stressed vegetation,

drainage patterns, field instrument measurements, odor, or other field indicators.

All media including soil, groundwater and soil vapor have been sampled and

evaluated in the RIR. Discrete (grab) samples have been used for final

delineation of the nature and extent of contamination and to determine the

impact of contaminants on public health and the environment. The sampling

performed and presented in this RIR provides sufficient basis for evaluation of

remedial action alternatives, establishment of a qualitative human health

exposure assessment, and selection of a final remedy.

Soil Sampling

Twenty-three soil samples were collected for chemical analysis during this RI.

Data on soil sample collection for chemical analyses, including dates of collection

and sample depths, is reported in Table 3. Figure 4 shows the location of

samples collected in this investigation. Laboratories and analytical methods are

shown below.

Lot 46

On 17 and 18 October 2011, six soil borings (ELB-1 through ELB-6) were

completed on Lot 46 (former parking lot area) in order to assess identified AOCs

(potential site-wide fill conditions and horizontal steam boilers) and groundwater

conditions. Three discrete soil samples (6-inch interval for VOCs and 2-foot

interval for the remaining analyses) were collected from each boring for

laboratory analysis from directly beneath the former parking lot, from

approximately one-foot into the native material, and from the base of the borings

at the soil bedrock interface.

20

LANGAN

Lot 40

On 27 and 28 October 2011, three soil borings (ELB-7 through ELB-9) were

completed in order to assess potential site-wide fill conditions and groundwater

conditions.

Two discrete soil samples (6-inch interval for VOCs and 2-foot interval for the

remaining analyses) were collected from each boring for laboratory analysis from

directly beneath the former building’s slab and from the base of the borings at

the soil bedrock interface. This deviates from the proposed three soil samples

per boring; however, based on the lack of fill material beneath the former

building slab it was determined that a third sample to determine vertical

delineation of impacts from the fill to the native material was not necessary.

All soil samples were submitted to Accutest Laboratories of Dayton, New Jersey,

a New York State Department of Health ELAP certified laboratory, for analysis for

volatile organic compounds (VOC), semi-volatile organic compounds (SVOC),

pesticides, polychlorinated biphenyls (PCB), and metal analysis.

Quality Assurance/Quality Control

All sampling devices (macrocores and split-spoons) were properly

decontaminated according to NYSDEC and ASTM (ASTM D-5088-90)

guidelines prior to each sampling location. This included a thorough

soap/water wash to remove solid residues, followed by successive rinses of

tap water and distilled/deionized water. Each macrocore was lined with a

dedicated acetate liner prior to the collection of each 5-foot long soil sample.

Soil samples were then placed in glass jars supplied by the laboratory. Each

soil sample was numbered and recorded in a field log book. Samples were

transferred to the laboratory immediately after field sampling was completed,

and were stored at a maximum of 4° Celsius. Chain-of-custody forms were

utilized to document custody for the acquisition, possession and analysis.

Quality assurance and quality control (field blanks and duplicate) samples were

incorporated into the sampling events as required by NYCOER and consisted of

one field blank and three duplicate samples. The soil field blank and duplicate

samples were analyzed for VOCs, SVOCs, PCBs, pesticides and metals.

21

LANGAN

Groundwater Sampling

Three groundwater samples were collected for chemical analysis during this RI.

Groundwater sample collection data is reported in Table 3. Sampling logs with

information on purging and sampling of groundwater monitor wells are included

in Appendix C. Figure 4 shows the location of groundwater monitoring wells.

Laboratories and analytical methods are discussed below.

In order to assess groundwater conditions on the subject property, three

groundwater monitoring wells (MW-1 through MW-3) were installed in soil

borings ELB-2 (MW-1), ELB-8 (MW-2) and ELB-6 (MW-3). A fourth groundwater

monitoring well was proposed in the Phase II Workplan at the ELB-9 location;

however, refusal was encountered directly beneath the former building’s slab

which prevented installation.

Following monitoring well development activities the wells were allowed to equalize

for a period of greater than 48-hours prior to sampling. On 1 November 2011, the

wells were purged via USEPA low-flow sampling methods. Groundwater field

parameters, including pH, specific conductivity, dissolved oxygen, oxidation-

reduction potential, temperature, and turbidity were measured during low-flow

purging activities. Groundwater Field Sampling Logs are provided in Appendix C.

Visual observations were made of groundwater samples that were collected

using dedicated polyethylene bladder pumps.

Groundwater grab samples were collected for analysis for VOCs, SVOCs,

pesticide, and PCBs. All samples were collected using dedicated polyethylene

bladder pumps and dedicated tubing. In addition, unfiltered groundwater

samples were collected for analysis for total metals and a second filtered sample

was collected for dissolved metals analysis. Due to a lack of groundwater

recovery for the MW-2 location, sufficient volume was not collected for analysis

for dissolved metals.

Quality Assurance/Quality Control

Collected groundwater samples were placed in containers supplied by the

laboratory with the appropriate preservatives. Each groundwater sample was

numbered and recorded in a field log book. Samples were transferred to the

laboratory immediately after field sampling was completed, and stored at a

maximum of 4° Celsius. Chain-of-custody forms were utilized to document

custody for the acquisition, possession and analysis.

22

LANGAN

Quality assurance (trip blank) and quality control (field blanks and duplicate)

samples were incorporated into the sampling events as required by NYCOER

and consisted of one field blank, one duplicate sample and one trip blank. The

groundwater field blank and duplicate samples were analyzed for VOCs, SVOCs,

PCBs, pesticides and metals. The trip blank was analyzed for VOCs only.

Soil Vapor Sampling

Four soil vapor probes were installed and four soil vapor samples were collected

for chemical analysis during this RI. Soil vapor sampling locations are shown in

Figure 4. Soil vapor sample collection data is reported in Table 3. Soil vapor

sampling logs are included in Appendix C. Methodologies used for soil vapor

assessment conform to the NYS DOH Final Guidance on Soil Vapor Intrusion,

October 2006.

In order to assess soil gas conditions and evaluate any potential vapor intrusion

conditions (pVICs) on the subject property, four temporary soil vapor points (SV-1

through SV-4) were installed in four of the soil borings (ELB-1, ELB-3, ELB-5 and

ELB-4) completed as part of the subsurface investigation activities. As shown in

Figure 4, each of the soil vapor points were installed at Lot 46 (former parking lot

area). One of the soil vapor points (SV-2) was placed in the vicinity of the former

horizontal steam boiler area, two (SV-3 and SV-4) were placed adjacent to Lot 40

(former building area) and the fourth was placed in the southwestern corner of

Lot 46. Each point was sampled as per NYCOER, NYSDOH, and NYSDEC

guidelines and samples were collected in accordance with NYSDOH

October 2006 Guidance for Evaluating Soil Vapor Intrusion in the State of

New York.

The temporary points were installed on 17 and 18 October 2011 by American

Environmental Assessment Corporation of Wyandanch, New York, (AEA) using a

track-mounted Geoprobe 7822DT Direct Push Drilling Rig. Soil vapor points

were constructed using six-inch stainless steel double woven screens and

Teflon-lined polyethylene tubing. The vapor points were completed using one-

foot of No. 0 sand pack; hydrated bentonite was placed above the sand pack to

surface grade. Three of the points (SV-1 through SV-3) were installed

approximately seven to eight-feet below sidewalk grade, and the forth point

(SV-4) was installed approximately thirteen-feet below sidewalk grade.

LANGAN

Each soil vapor sampling point was tightness tested using the helium tracer gas

method and purged at a flow-rate of <200-ml per minute for at least five

minutes. No evidence of helium breakthrough (i.e. helium concentrations above

5%) was observed in any of the sample locations either before or after sample

collection. Photo-ionization detector (PID) readings for volatile organic

compounds (VOCs) ranging from 3045 ppb (SV-4) to 549 ppb (SV-3) were

observed during field screening of each location.

Soil gas samples were laboratory analyzed for VOCs via USEPA TO-15 Method.

Samples were collected in laboratory-cleaned and certified evacuated 6-L

stainless steel summa canisters with regulators supplied by Accutest

Laboratories of Dayton, New Jersey. The regulators were set to collect each

sample over a 2-hour sampling period (a flow-rate of <200-ml per minute) as per

USEPA/ITRC soil vapor sampling guidance. Each soil gas sample was numbered

and recorded in a field log book. Samples were transferred to the laboratory

immediately after field sampling was completed, and stored at a maximum

room temperature of 30° Celsius. Chain-of-custody forms were utilized to

document custody for the acquisition, possession, and analysis.

An ambient blank sample was collected for quality assurance and quality control

sample was incorporated into the sampling events as required by NYS DOH

Final Vapor Intrusion Guidance. The ambient blank was analyzed for TO-15.

this RIR are provided in digital form in Appendix D.

Soil Sample Results

All soil analytical results were compared to the NYSDEC 6 NYCRR Subpart 375-

6 Remedial Program Soil Cleanup Objectives. Analytical results revealed no

exceedances of Unrestricted Use Objectives for VOCs in any of the soil

samples collected. There were no exceedances to the Unrestricted Use

Objectives for SVOCs in any of the samples collected with the following

exceptions. Polycyclic aromatic hydrocarbons (PAHs) were detected in soil

samples collected from the shallow interval of ELB-2 (0-2 feet b.g.s.), ELB-5

25

LANGAN

(0-2 feet b.g.s.) and ELB-6 (0-2 feet b.g.s.) in exceedance of Unrestricted Use

Objectives, as well as the Protection of Public Health Restricted-Residential and

Restricted-Commercial objectives. Additionally, in ELB-2 (benzo(a)anthracene,

benzo(a)pyrene, benzo(k)fluoranthene and dibenzo(a,h)anthracene), ELB-5

(benzo(a)anthracene, benzo(a)pyrene, benzo(k)fluoranthene, dibenzo(a,h)anthracene

and indeno(1,2,3-cd)pyrene), and ELB-6 (benzo(a)anthracene, benzo(a)pyrene and

dibenzo(a,h)anthracene) SVOCs were detected in the shallow interval above the

Protection of Public Health Restricted-Industrial criteria.

Pesticides (4,4-DDE, 4,4-DDT and 4,4-DDD) were detected marginally above

the Unrestricted Use Objectives in the samples collected from the shallow

sample interval in ELB-1 (0-2 feet b.g.s.), ELB-2 (0-2 feet b.g.s.), ELB-3 (0-2 feet

b.g.s.), ELB-5 (0-2 feet b.g.s.) and ELB-6 (3.5-4 feet b.g.s. No other

exceedances of the Unrestricted Use Objectives were detected in any of the

remaining samples collected.

PCBs (arochlor 1254 and arochlor 1260) were detected marginally above the

Unrestricted Use Objectives in the samples collected from the shallow sample

interval in ELB-1 (0-2 feet b.g.s.) and ELB-6 (0-2 feet b.g.s.). No other


remaining samples collected.

Several metals (copper, iron, lead, mercury, nickel and zinc) were detected

above Unrestricted Use Objectives in the samples collected from the shallow

interval (0-2 feet b.g.s.) in ELB-1 through ELB-6. In ELB-1 copper was detected

above Unrestricted Use Objectives in the sample collected from in the

15-17 foot b.g.s. interval and nickel and zinc were detected above the

Unrestricted Use Objectives in the sample collected from the 25-27 foot b.g.s.

Groundwater Sample Results

No exceedances to NYSDEC Part 703 Groundwater Quality Standards for

SVOCs, pesticides or PCBs were detected. VOCs were detected in exceedance

of the NYSDEC Part 703 Groundwater Quality Standards in the MW-1 and MW-2

groundwater samples. 1,2-cis dichloroethene (DCE) (14.4 µg/l), tetrachloroethene

(PCE) (5.8 µg/l) and trichloroethene (TCE) (6.8 µg/l) were detected in upgradient

well MW-1 above the 5 µg/l criteria. Acetone (7.6 µg/l) and chloroform (50.3 µg/l)

were detected above their 5 and 7 µg/l criteria respectively in the MW-2 sample.

No other VOC exceedances were reported.

Lead was detected in exceedance of the NYSDEC Part 703 Groundwater Quality

Standard of 25 µg/l in the total metals sample collected at the MW-2 location at

101 µg/l. With exception of the previously mentioned lead exceedance and the

exceedance of iron, manganese, selenium and sodium no other metals

exceedences of the NYSDEC Part 703 Groundwater Quality Standards were

reported in the groundwater samples collected from MW-1, MW-2 and MW-3.

Soil Vapor Results

Several VOCs were detected in soil below the Unrestricted Use Objectives and

several VOCs were detected in groundwater samples both above and below

NYSDEC Part 703 Groundwater Quality Objectives. The following VOCs were

detected in soil:

1,2-Dichloroethene (cis)

Carbon Disulfide

Tetrachloroethene

Toluene

Trichloroethene

1,2-Xylene (o-Xylene)

Xylene (mixed)

The following is a list of the VOCs detected in the groundwater samples

collected as part of this investigation:

1,2-Dichloroethene (cis)

Acetone

Bromodichloromethane

Chloroform

27

LANGAN

Tetrachloroethene

Toluene

Trichloroethene

Vinyl Chloride

Based on the list of detected compounds and identified AOCs, the combined list

of compounds will be considered for the potential for a vapor intrusion condition.

Based on the list of compounds evaluated as part of this Remedial Investigation,

xylenes were detected in all four of the soil vapor samples above the 2003 Study

of Volatile Organic Chemicals in Air of Fuel Oil Heated Homes guidance values.

Additionally, chloroform (6.3 µg/m3 in SV-3) and toluene (50.5 µg/m3 in SV-4)

were detected above the 2003 Study of Volatile Organic Chemicals in Air of Fuel

Oil Heated Homes guidance values. PCE was detected at concentrations

ranging from 3.9 to 7.5 µg/m3 in three of the four samples (SV-2 through SV-4),

which is below the 2006 New York State Department of Health Soil Vapor

Intrusion Guidance value for sub-slab concentrations of 100 µg/m3. Based on

these detected PCE values, according to Matrix 2 no further action is required.

5.0 ENVIRONMENTAL EVALUATION

5.1 Geological and Hydrogeological Conditions

Stratigraphy

Based on the borings completed for this Remedial Investigation, site subsurface

conditions at Lot 46 generally consist of successive strata of fill, native silt, and

mica schist bedrock. The fill extends to depths ranging from approximately 5 to

13-feet below sidewalk grade and generally consists of sand, gravel, brick,

concrete, and asphalt. The fill is underlain by native silt with sand and gravel.

Mica schist bedrock was encountered at depths ranging from 20 to 30-feet

below the existing site grades.

Four test borings were installed in the former building area (Lot 40); as part of

this investigation and three of the borings encountered demolition debris which

was used to fill the former building basement, the fourth boring was advanced

from directly on top of the former building slab. As part of the proposed site

development the debris will be removed and disposed as demolition debris;

therefore, no sampling was completed within the debris. Borings were

advanced beneath the former building basement slab (approximately 12-feet

28

LANGAN

below sidewalk grade) and continuous spilt spoon sampling was completed for

all the material located beneath the former building slab. The subsurface

conditions beneath the former building were observed to generally consist of

successive layers of native silt and refusal on presumed mica schist rock. Fill

material was not encountered beneath the former building basement slab during

the Remedial Investigation; however, a geotechnical investigation completed by

Langan and summarized in a 16 January 2012 Confirmation Geotechnical Report

identified that less than 4-feet of fill was encountered in the borings completed.

This report also identified that a layer of decomposed rock was encountered

beneath the native material that was observed to be approximately 2 to 16-feet

thick.

Hydrogeology

A table of water level data for all monitor wells is included in Table 2. The

average groundwater elevation is 17.75-feet amsl and the range in elevation is

17.23 to 18.34-feet amsl. A map of groundwater level elevations with

groundwater contours and inferred flow lines is shown in Figure 5. Groundwater

flow is from west southwest to north northeast.

5.2 Soil Chemistry

Data collected during the RI is sufficient to delineate the vertical and horizontal

distribution of contaminants in soil/fill at the Site. A summary table of data for

chemical analyses performed on soil samples is included in Table 4. Figure 6

shows the location and posts the values for soil/fill that exceed the 6NYCRR Part

375-6.8 Track 1 Soil Cleanup Objectives.

The soil analytical results of this Remedial Investigation showed no VOCs

above Track 1 unrestricted use SCOs (Track 1 SCOs). Seven SVOCs

exceeding Track 2 Restricted Residential SCOs in three samples. All of

these compounds were PAH and concentrations were consistent with

findings of historical fill during soil sampling. Three pesticides were

detected above Track 1 in three samples but did not exceed Track 2

Restricted Residential SCOs. Similarly, PCBs were detected in two samples

above Track 1 in three samples but did not exceed Track 2 Restricted

Residential SCOs. The metals mercury, nickel and zinc exceeded Track 1

SCOs in between one and 6 samples but did not exceed Track 2 Restricted

Residential SCOs. Barium, cadmium and copper exceeded Track 2

Restricted Residential SCOs in only one sample each. Only lead exceeded

29

LANGAN

Track 2 Restricted Residential SCOs in only two soil samples. Overall, the

soil findings were unremarkable and did not indicate any evidence of an

onsite contaminant source. Low level contamination that was observed can

be explained by the presence of historical fill. This layer of fill material was

observed throughout Lot 46 from approximately 5 to 13-feet below current

grades and contained varying quantities of sand, brick, concrete, gravel and silt,

and was underlain by a native silt layer.

5.3 Groundwater Chemistry

Data collected during the RI is sufficient to delineate the distribution of

contaminants in groundwater at the Site. A summary table of data for chemical

analyses performed on groundwater samples is included in Table 5,

exceedences of applicable groundwater standards are shown. Figure 7 shows

the location and posts the values for groundwater that exceed the New York

State 6NYCRR Part 703.5 Class GA groundwater standards.

The groundwater analytical results showed no exceedances to NYSDEC Part 703

Groundwater Quality Standards (GWQS) for SVOCs, pesticides or PCBs. VOCs

were detected in exceedance of the NYSDEC Part 703 Groundwater Quality

Standards in the upgradient well MW-1 for 1,2-cis dichloroethene (DCE),

tetrachloroethene (PCE), and trichloroethene (TCE) Acetone and chloroform

were detected at low concentrations in the MW-2 sample. No other VOC

exceedances were reported.

Dissolved metals in groundwater included sodium, manganese and silver above

GWQS. Sodium and manganese are attributed to background water quality

influences and silver was only marginally above the standard in one sample. No

other metals exceedences of the NYSDEC Part 703 Groundwater Quality

Standards were reported for dissolved groundwater samples collected at the

site.

5.4 Soil Vapor Chemistry

Data collected during the RI is sufficient to delineate the distribution of

contaminants in soil vapor at the Site. A summary table of data for chemical

analyses performed on soil vapor samples is included in Table 6.

Figure 8 shows the location and posts the values for soil vapor samples with

detected concentrations.

30

LANGAN

The soil vapor analytical results for this Remedial Investigation showed very low

levels of PCE and well below the sub-slab guidance value to initiate monitoring

(all results were below 8 ug/m3 compared to the monitor level of 100 ug/m3).

TCE was not detected in four soil vapor samples. Low levels of xylenes and

acetone were detected in most soil vapor samples. One very low level of

chloroform (less than 7 ug/m3) was detected in one of four samples. No VOCs

were detected in soil samples from the site above Track 1 SCOs. Several

chlorinated hydrocarbons were detected in an upgradient groundwater sample

and suggest an offsite source for these compounds to the west of the property.

5.5 Prior Activity

Based on an evaluation of the data and information from the RIR, disposal of

significant amounts of hazardous waste is not suspected at this site.

5.6 Impediments to Remedial Action

There are no known impediments to remedial action at this property.
