  1. What are decibel-based noise ordinances?
    A decibel-based noise ordinance is based on the noise control provisions enacted pursuant to the state Noise Control Act, Ch. 70.107 RCW. This Act authorizes the State Department of Ecology to establish maximum noise levels in identified areas or environments. See RCW 70.107.030(1). Local governments may enact similar provisions establishing noise limitations for areas within their jurisdictions. Any difference between the local regulations and those provided for by the state must be approved by the Department of Ecology. See RCW 70.107.060(3). If the state has not acted within 90 days after a local ordinance has been submitted to it, the local provision is automatically approved.

    The rules adopted by DOE establishing maximum permissible noise levels are contained in Chapter 173-60 WAC, relating to maximum environmental noise levels, and Chapter 173-62 WAC, relating to motor vehicle noise performance standards.

  2. How do Washington cities and counties deal with noise problems?
    Most Washington jurisdictions follow two basic approaches to control noise problems: (1) adoption of noise control provisions based upon the state Noise Control Act utilizing decibel-based standards; (2) adoption of subjective "public disturbance noise" standards which do not require the use of decibel meters for enforcement; or a combination of these two basic approaches.
