Which agencies oversee Phase I ESAs in Washington?

Accepted Answer

Phase I ESAs in Washington are read against Washington Department of Ecology (Toxics Cleanup Program); Ecology regional offices (NW, SW, Central, Eastern); Local health / contaminated-site programs (King, Pierce, Spokane), on top of ASTM E1527 and 40 CFR 312 All Appropriate Inquiries.

Question 2

What standards and state overlays apply to Phase I ESAs in Washington?

Accepted Answer

Key standards and overlays include ASTM E1527 / 40 CFR 312 AAI, Model Toxics Control Act (MTCA), Voluntary Cleanup Program (VCP), Ecology Facility/Site Atlas and Cleanup Site Search. ASTM E1527 / 40 CFR 312 AAI and Model Toxics Control Act (MTCA) are the usual reason a national database pass is not enough.

What site settings commonly produce RECs in Washington?

Accepted Answer

Common REC settings in Washington include Wood treating and smelters, Dry cleaners / PCE vapor, Ports, shipyards, and creosote, UST corridors, Orchard and ag chem (central WA). State cleanup lists and tank programs often contradict a 'closed' national listing.
