TagWashington Administrative Code(9)

This document outlines Washington State campaign finance laws related to political contributions, coordination, and reporting requirements. It defines when an expenditure made by a third party counts as a campaign contribution — particularly when made in coordination with a candidate or political committee — and sets out registration and disclosure deadlines for political committees. These rules govern how campaigns and political organizations must track and report donations and spending.

Exhibit 137 (AR 018038), WAC 173-201A-050, Title 173 Washington Administrative Code, Washington State Department of Ecology ambient water quality criteria footnotes. Covers dissolved metals criteria, weak acid dissociable cyanide method (Standard Methods 4500-CN I), total recoverable effluent limits, conversion factors, water effects ratio approach (USEPA Water Quality Standards Handbook December 1983), site-specific metals adjustment, seasonal

This Washington State administrative regulation establishes rules for 'mixing zones,' which are designated areas in bodies of water where pollutant discharges are allowed to mix and dilute before meeting water quality standards. The rules set strict size limits for mixing zones in rivers, estuaries, lakes, and ocean waters, and require that dischargers apply all available pollution-reduction technology before a mixing zone is approved. Special provisions are also included for storm water discharges and combined sewer overflows.

Washington Administrative Code (WAC) 173-201A sections 030, 040, 050, and 060 covering water quality standards for surface waters in Washington State, published by the Washington State Department of Ecology. Exhibit 113 (AR017890–AR017892) includes: lake total phosphorus (TP) nutrient criteria by ecoregion (Cascades, Columbia Basin, Willamette, East Cascade Foothills, Blue Mountain) with trophic state classifications (ultra-oligotrophic,

WAC Chapter 173-201A establishes water quality standards for surface waters of the State of Washington under RCW 90.48, including definitions for AKART, background conditions, best management practices (BMP), fecal coliform, mixing zones, pH, turbidity, wetlands, nonpoint source pollution, and trophic state. Covers general water use and criteria classes (Class AA extraordinary), dissolved oxygen standards, fecal

Washington Administrative Code (WAC) Chapter 173-201A, Water Quality Standards for Surface Waters of the State of Washington, issued by the Washington State Department of Ecology under RCW 90.48. Covers introduction (WAC 173-201A-010) and definitions (WAC 173-201A-020) including AKART, background conditions, best management practices, carcinogen, chronic/acute conditions, critical condition (7Q10 flow), ecoregions, fecal coliform, hardness, mixing

WAC 246-366-110 sets sound control standards for Washington State school classrooms, requiring that background noise in new construction not exceed NC-35 on the noise criterion curve, with actual noise levels capped at 45 dBA during normal operation. Industrial and vocational classrooms have separate limits, with ambient noise not to exceed 65 dBA when exhaust systems are running. In music and vocational education areas, student noise exposure is strictly regulated by duration, and hearing protection must be provided if exposure limits are exceeded.

Washington State law (WAC 173-60-040) sets maximum allowable noise levels based on the zoning class of both the noise source and the receiving property, ranging from 55 to 70 dBA, with nighttime limits reduced by 10 dBA for residential areas between 10 p.m. and 7 a.m. Short-duration noise spikes are permitted, allowing up to 15 dBA above the limit for no more than 1.5 minutes per hour. Enforcement is complaint-driven, measured at the receiving property, and each 24-hour period of violation counts as a separate offense under RCW 70.107.050.
