King County Code and Public Rule changes, 2008 - 10

Changes to King County Code Title 28 adopted fall 2010:
As a result of amendments to the U.S. Environmental Protection Agency's (EPA's)  Pretreatment Streamlining Final Rule (below), KCIW  proposed changes to King County Code 28.84.060 28.84.060, Establishing the Fees, Rules, and Regulations for the Disposal of Industrial Waste into the Metropolitan Sewerage System that governs the discharge of industrial waste into the wastewater treatment system. KCIW also proposed several changes to clarify or enhance King County's existing regulations and to acknowledge other changes in federal requirements. These changes were adopted by the King County Council in fall 2010.

KCIW provided an article highlighting the proposed changes in pages 7-10 of its fall 2010 newsletter (PDF).

Streamlining rule amendments: The EPA's Pretreatment Streamlining Final Rule (external link) became effective in 2005, updating the National Pretreatment Program. The purpose of the new streamlining rule is to reduce the burden of and provide flexibility in technical and administrative requirements for industrial users and publicly owned treatment works while continuing to protect the environment.

Revised Public Rules that became effective in 2008: The Industrial Waste Program proposed revisions to two King County Public Rules that became effective on September 15, 2008. The two rules (Local Limits and Enforcement Response Plan) have been revised in order to comply with changes required by streamlining amendments (see above). Revised rules are:

New Hauled Waste Rule that became effective in 2008: The Industrial Waste Program had also proposed a new King County Public Rule allowing the discharge of hauled waste at a King County treatment plant. This rule became effective on September 15, 2008. The new rule describes procedures to allow the discharge of non-domestic septage, commercial wastes, industrial wastes, and grease removed from a grease trap, septic tank, or cesspool into a designated septage facility in King County.
