SURROUNDING SITES: SEARCH RESULTS

Surrounding sites were identified in the following databases.

EXECUTIVE SUMMARY


Elevations have been determined from the USGS Digital Elevation Model and should be evaluated ona relative (not an absolute) basis. Relative elevation information between sites of close proximityshould be field verified. Sites with an elevation equal to or higher than the target property have beendifferentiated below from sites with an elevation lower than the target property.Page numbers and map identification numbers refer to the EDR Radius Map report where detaileddata on individual sites can be reviewed.

Sites listed in bold italics are in multiple databases.

Unmappable (orphan) sites are not considered in the foregoing analysis.



LUST: The Leaking Underground Storage Tank Incident Reports contain an inventory of reportedleaking underground storage tank incidents. The data come from the State Water Resources Control Board LeakingUnderground Storage Tank Information System.

A review of the LUST list, as provided by EDR, and dated 01/20/2012 has revealed that there is 1 LUST site within approximately 1.5 miles of the target property.

EXECUTIVE SUMMARY


HAZNET: The data is extracted from the copies of hazardous waste manifests received each year bythe DTSC. The annual volume of manifests is typically 700,000-1,000,000 annually, representing approximately350,000-500,000 shipments. Data from non-California manifests & continuation sheets are not included at thepresent time. Data are from the manifests submitted without correction, and therefore many contain someinvalid values for data elements such as generator ID, TSD ID, waste category, & disposal method. The sourceis the Department of Toxic Substance Control is the agency

A review of the HAZNET list, as provided by EDR, and dated 12/31/2010 has revealed that there are 6 HAZNET sites within approximately 1 mile of the target property.

To maintain currency of the following federal and state databases, EDR contacts the appropriate governmental agencyon a monthly or quarterly basis, as required.

Number of Days to Update: Provides confirmation that EDR is reporting records that have been updated within 90 daysfrom the date the government agency made the information available to the public.



NPL: National Priority ListNational Priorities List (Superfund). The NPL is a subset of CERCLIS and identifies over 1,200 sites for prioritycleanup under the Superfund Program. NPL sites may encompass relatively large areas. As such, EDR provides polygoncoverage for over 1,000 NPL site boundaries produced by EPA’s Environmental Photographic Interpretation Center(EPIC) and regional EPA offices.

DELISTED NPL: National Priority List DeletionsThe National Oil and Hazardous Substances Pollution Contingency Plan (NCP) establishes the criteria that theEPA uses to delete sites from the NPL. In accordance with 40 CFR 300.425.(e), sites may be deleted from theNPL where no further response is appropriate.




CERCLIS: Comprehensive Environmental Response, Compensation, and Liability Information SystemCERCLIS contains data on potentially hazardous waste sites that have been reported to the USEPA by states, municipalities,private companies and private persons, pursuant to Section 103 of the Comprehensive Environmental Response, Compensation,and Liability Act (CERCLA). CERCLIS contains sites which are either proposed to or on the National PrioritiesList (NPL) and sites which are in the screening and assessment phase for possible inclusion on the NPL.

CERCLIS-NFRAP: CERCLIS No Further Remedial Action PlannedArchived sites are sites that have been removed and archived from the inventory of CERCLIS sites. Archived statusindicates that, to the best of EPA’s knowledge, assessment at a site has been completed and that EPA has determinedno further steps will be taken to list this site on the National Priorities List (NPL), unless information indicatesthis decision was not appropriate or other considerations require a recommendation for listing at a later time.This decision does not necessarily mean that there is no hazard associated with a given site; it only means that,based upon available information, the location is not judged to be a potential NPL site.

The list represents deedrestrictions that are active. Some sites have multiple deed restrictions. The DTSC Hazardous Waste ManagementProgram (HWMP) has developed a list of current or former hazardous waste facilities that have a recorded landuse restriction at the local county recorder’s office. The land use restrictions on this list were required bythe DTSC HWMP as a result of the presence of hazardous substances that remain on site after the facility (orpart of the facility) has been closed or cleaned up. The types of land use restriction include deed notice, deedrestriction, or a land use restriction that binds current and future owners.

Manufactured Gas Plants: EDR Proprietary Manufactured Gas PlantsThe EDR Proprietary Manufactured Gas Plant Database includes records of coal gas plants (manufactured gas plants)compiled by EDR’s researchers. Manufactured gas sites were used in the United States from the 1800’s to 1950’sto produce a gas that could be distributed and used as fuel. These plants used whale oil, rosin, coal, or a mixtureof coal, oil, and water that also produced a significant amount of waste. Many of the byproducts of the gas production,such as coal tar (oily waste containing volatile and non-volatile chemicals), sludges, oils and other compoundsare potentially hazardous to human health and the environment. The byproduct from this process was frequentlydisposed of directly at the plant site and can remain or spread slowly, serving as a continuous source of soiland groundwater contamination.

A soil map in a soil survey is a representationof soil patterns in a landscape. Soil maps for STATSGO are compiled by generalizing more detailed (SSURGO)soil survey maps.

SSURGO: Soil Survey Geographic DatabaseSource: Department of Agriculture, Natural Resources Conservation Services (NRCS)Telephone: 800-672-5559SSURGO is the most detailed level of mapping done by the Natural Resources Conservation Services, mappingscales generally range from 1:12,000 to 1:63,360. Field mapping methods using national standards are used toconstruct the soil maps in the Soil Survey Geographic (SSURGO) database. SSURGO digitizing duplicates theoriginal soil survey maps. This level of mapping is designed for use by landowners, townships and countynatural resource planning and management.

TOPOGRAPHIC INFORMATION

USGS 7.5’ Digital Elevation Model (DEM)Source: United States Geologic SurveyEDR acquired the USGS 7.5’ Digital Elevation Model in 2002 and updated it in 2006. The 7.5 minute DEM correspondsto the USGS 1:24,000- and 1:25,000-scale topographic quadrangle maps. The DEM provides elevation datawith consistent elevation units and projection.


HYDROLOGIC INFORMATION



HYDROGEOLOGIC INFORMATION

AQUIFLOW Information SystemR

Source: EDR proprietary database of groundwater flow informationEDR has developed the AQUIFLOW Information System (AIS) to provide data on the general direction of groundwater

flow at specific points. EDR has reviewed reports submitted to regulatory authorities at select sites and hasextracted the date of the report, hydrogeologically determined groundwater flow direction and depth to water tableinformation.

A soil map in a soil survey is a representationof soil patterns in a landscape. Soil maps for STATSGO are compiled by generalizing more detailed (SSURGO)soil survey maps.

SSURGO: Soil Survey Geographic DatabaseSource: Department of Agriculture, Natural Resources Conservation Services (NRCS)Telephone: 800-672-5559SSURGO is the most detailed level of mapping done by the Natural Resources Conservation Services, mappingscales generally range from 1:12,000 to 1:63,360. Field mapping methods using national standards are used toconstruct the soil maps in the Soil Survey Geographic (SSURGO) database. SSURGO digitizing duplicates theoriginal soil survey maps. This level of mapping is designed for use by landowners, townships and countynatural resource planning and management.
