DEPARTMENT OF ECOLOGY, TOXICS CLEANUP PROGRAM
SITE INFORMATION SYSTEM
LEGEND FOR: CONFIRMED & SUSPECTED CONTAMINATED SITES REPORT
Revised May, 1999
THIS REPORT IS SUBJECT TO REVISION. Within 90 days of learning of a potentially contaminated site, the Department of Ecology conducts an initial investigation of each site. If the initial investigation shows that further action is needed, the site will appear in the Confirmed & Suspected Contaminated Sites (CSCS) Report. Once remedial action has been completed, the Toxics Cleanup Program's management determines the removal of a site from the CSCS Report. The Hazardous Sites List is a subset of the CSCS Report. It contains those sites that have been ranked using the Washington Ranking Method.
Ecology does not list Voluntary Cleanup Program (VCP - formerly Independent Remedial Action Program) sites on our public lists as an incentive to encourage Potentially Liable Persons to go through the VCP process. This informal review process is usually finished in a few months and in 80% of cases results in a no further action decision. If further cleanup of a site is needed, and the responsible parties choose not to do the required follow-up work, the site would then become a formal site and would appear in this report.
PLEASE NOTE:
1. Site owners and operators do not necessarily agree with Ecology's determination of site status.
2. Ecology will update the site list continually as new information becomes available.
REPORT ORGANIZATION: The information in this report is sorted by county. Within each county, the data are sorted by site name.
SITE STAT CODE = ECOLOGY SITE STATUS: Indicates the current status of sites relative to the MTCA cleanup process. Code choices are:
1 Awaiting Site Hazard Assessment (SHA)
2 Ranked, Awaiting Remedial Action (RA)
3 Remedial Action in progress
4 Independent Remedial Action
5 Construction Completed, Operation & Maintenance Underway
6 RA Completed, Confirmational Monitoring Underway
7 RA Conducted, residual contamination left on site; on-going institutional controls required
8 RA and all activities completed (no monitoring)
IND SITE STAT = INDEPENDENT SITE STATUS: This column only applies to those sites undergoing an independent cleanup. Code choices are:
1 Release report received, awaiting assessment by PLP
(PLP = Potentially Liable Person)
2 Independent Site Assessment or Interim RA Report received
3 Final Independent RA Report received
WARM BIN#: Indicates the outcome of the WAshington Ranking Model (WARM). The WARM BIN Number will be a number between 1 and 5. A result of 1 indicates the greatest assessed risk to human health and to the environment. A result of 5 indicates the lowest assessed risk. A zero indicates that the site is either on the federal National Priorities List (NPL) or a sub-site or operable unit of an NPL site. NPL sites are ranked under the federal Hazard Ranking System (HRS).
AFFECTED MEDIA: For each site, there may be contaminant information for up to six environmental media: Groundwater, surface water, air, soil, sediment or drinking water.
The media status column and the numbered contaminant type columns may be coded:
C (Confirmed) - The presence of hazardous substances above MTCA cleanup levels has been confirmed by laboratory analysis (or field determination in the case of petroleum contamination).
B (Below) - The presence of hazardous substances below MTCA cleanup levels has been confirmed by laboratory analysis (or field determination in the case of petroleum products). The B code may only be applied following completion of analytical work in conjunction with a Site Hazard Assessment (SHA) or Remedial Investigation/Feasibility Study (RI/FS).
S (Suspected) - Due to preliminary investigations or the nature of business operations or manufacturing processes, certain contaminants are suspected to be present at the site.
R (Remediated) - Contaminants have been treated, removed, or contained to meet cleanup levels established for the site. (This status determination may only be made by Ecology.)
CONTAMINANT GROUPS--DEFINITIONS AND EXAMPLES:
NUMBERS 1 THROUGH 17 CORRESPOND TO THE CONTAMINANT NUMBERS ON THE ATTACHED REPORT OR IN THE ELECTRONIC DATA SET.
1. Base/Neutral/Acid Organics: Hazardous substances typically included in the Base/Neutral/Acid fraction of EPA's priority pollutant compound list. Examples are: Acenaphthene; Hexachloro-benzene; Fluoranthene; 2,4-dinitro-toluene; Isophorone.
2. Halogenated Organic Compounds: Organic compounds, typically solvents, with one or more of the halogens (e.g., Chlorine, Bromine, Fluorine) incorporated into their structure. Examples are: Carbon Tetrachloride; Chloroform; Vinyl Acetate; 1,1,2,2-tetrachloroethane; freons.
3. EPA Priority Pollutants - Metals and Cyanide: Metals included in EPA's priority pollutant compounds list. Examples are: Antimony, Arsenic, Beryllium, Cadmium, Chromium, Copper, Cyanide, Lead, Mercury, Nickel, Selenium, Silver, Thallium and Zinc.
4. Metals - Other: Other non-priority pollutant metals. Examples are: Aluminum, Barium, Cobalt, Iron, Manganese and Tin.
5. Polychlorinated biPhenyls (PCBs): A specific "family" of aromatic chlorinated organic compounds, often referred to as "AROCLOR." Common types are: AROCLOR-1016, AROCLOR-1221, AROCLOR-1260.
6. Pesticides: Chemical agents used to control pests such as: fungicides, herbicides and insecticides. Examples are: Aldrin, Chlordane, Endrin, Diazinon, Folex, Malathion.
7. Petroleum Products: Crude oil and any fraction thereof. Each of these materials may consist of many specific chemical compounds. Examples are: Gasoline, diesel fuel, mineral oil.
8. Phenolic Compounds: Hazardous substances typically included in the acid extractable fraction of EPA's priority pollutant compound list. Examples are: 2,4,6-trichloro-phenol; Phenol; Cresols; Pentachlorophenol; Benzoic Acid.
9. Non-Halogenated Solvents: Organic solvents, typically volatile or semi-volatile, not containing any halogens. Examples are: Acrolein; Benzene; Toluene; Acetone; 4-Methyl-2-pentanone.
10. Dioxin: A family of more than 70 compounds of chlorinated dioxins. Examples: 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD); P-dioxin; Hexachlorodibenzo-p-dioxin; Polychlorinated dibenzo-para-dioxin (PCDD).
11. Polynuclear Aromatic Hydrocarbons (PAH): Hydrocarbons composed of two or more benzene rings. Examples are: Benzo-Fluoranthene; Chrysene; Anthracene; Acenapthene.
12. Reactive Wastes: Wastes that react violently upon contact with other substances (especially air or water) as defined by the Dangerous Waste Regulation (WAC 173-303-090(7)). They explode easily or are otherwise unstable. Examples: Peroxides; Metallic Sodium.
13. Corrosive Wastes: Wastes that are highly corrosive as defined by the Dangerous Waste Regulation (WAC 173-303-090(6)). Substances with very high (base) or very low (acid) pH. Examples: Nitric Acid, Sodium Hydroxide.
14. Radioactive Wastes: Wastes that emit more than background levels of radiation. Examples are: High and low level nuclear wastes; mixed nuclear wastes; Uranium mine tailings.
15. Conventional Contaminants, Organic: Unspecified organic matter that imposes an oxygen demand during its decomposition. This is reflected by elevated Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD) and/or Total Organic Carbon (TOC). Typically a component of municipal solid waste leachates, sewage, septage, food wastes, wood waste leachate and similar organic wastes.
16. Conventional Contaminants, Inorganic: Non-metallic inorganic substances or indicator parameters that may indicate the existence of contamination if present at unusual levels. Examples are: Chloride, Sulfur compounds, Nitrogen compounds, pH, conductivity, hardness and alkalinity.
17. Asbestos: All forms of Asbestos. Asbestos fibers have been used in products such as building materials, friction products, and heat-resistant materials.
