Chapter 173-351 WAC
Criteria for Municipal Solid Waste Landfills

Timeline

The Department of Ecology has adopted revisions to Appendix 3 of WAC 173-351-990 to include two hazardous organic constituents: 2,3,7,8-Tetrachlorodibenzo- p-dioxin - [CAS 1746-01-6] and alpha, alpha-Dimethylphenethylamine [CAS 122-09-8]. This revision affects landfills that are required to perform assessment monitoring under the rule, and is necessary to be consistent with federal rules in 40 CFR Part 258. Operators of municipal solid waste landfills must meet federal program requirements. Revising our rule eliminates possible noncompliance for facilities that inadvertently omit the two additional constituents required to be monitored under federal rules. It also clarifies monitoring requirements for local jurisdictional health authorities that have the lead for issuing and enforcing solid waste permits. These revisions will enable Ecology to obtain full approval of our municipal solid waste program from the U.S.

The revised rule will be effective on November 6, 2015.
