AS REPORTED BY COMMITTEE ON PARKS & ECOLOGY, FEBRUARY 10, 1987

BACKGROUND:

Incineration has become a leading option for solid waste disposal among many cities and counties in the state.  Several are seriously considering incinerators, and a few, including Spokane and Tacoma, are currently building facilities.  Incinerators have been viewed as more desirable than landfills for disposing of garbage.  Several landfills in the state are creating environmental problems such as groundwater contamination and methane gas migration.

Disposal of incinerator ash may be difficult given current state law.  The Department of Ecology conducted a multi-state study this past summer to measure the toxicity of incinerator ash residues.  The Department found that "bottom ash" (a relatively heavy ash residue that does not become airborne after combustion) would probably be marginally designated as a dangerous waste under current state law.  It also found that "fly ash" (a relatively light ash residue that does become airborne after combustion) exhibited properties that would likely designate it as either a dangerous or extremely hazardous waste.  State law regulating hazardous wastes is currently more stringent than federal law.

Incineration may not be an economically feasible option if the ash residues must be transported to hazardous waste landfills.  Many states and countries allow incinerator ash to be disposed in traditional solid waste landfills.  Washington has not yet addressed the issue.

SUMMARY:

The Department of Ecology will regulate ash residues from solid waste incinerators as "special wastes".  Under this designation, incinerator ash residues will be disposed of in municipal solid waste landfills, provided that the ash meets all appropriate federal requirements.

The Department is given broad authority to require additional standards for the design, construction, and operation of landfills.

Owners and/or operators of municipal incinerators are to develop plans, prior to disposal, regarding the handling and management of fly ash residues.  Management plans will be subject to the Department's review and approval.

Fiscal Note:      requested

EFFECT OF PROPOSED SUBSTITUTE:

The Department of Ecology will have 90 days to complete the permit procedure unless the project proponents and the Department agree to a longer time period.

Specific statutory authority to require a manifest system or to establish standards for the transport, storage, treatment, or disposal of special wastes is no longer provided.
