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.

EPA WATCH LIST: EPA WATCH LISTEPA maintains a "Watch List" to facilitate dialogue between EPA, state and local environmental agencies on enforcementmatters relating to facilities with alleged violations identified as either significant or high priority. Beingon the Watch List does not mean that the facility has actually violated the law only that an investigation byEPA or a state or local environmental agency has led those organizations to allege that an unproven violationhas in fact occurred. Being on the Watch List does not represent a higher level of concern regarding the allegedviolations that were detected, but instead indicates cases requiring additional dialogue between EPA, state andlocal agencies - primarily because of the length of time the alleged violation has gone unaddressed or unresolved.

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.

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.

STATSGO: State Soil Geographic DatabaseSource: Department of Agriculture, Natural Resources Conservation ServicesThe U.S. Department of Agriculture’s (USDA) Natural Resources Conservation Service (NRCS) leads the nationalConservation Soil Survey (NCSS) and is responsible for collecting, storing, maintaining and distributing soilsurvey information for privately owned lands in the United States. 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.
