State Regulations

  • Western Washington Phase II Municipal Stormwater Permit
    All stormwater runoff flowing through Olympia's pipes, ponds, and ditches must now be managed according to the requirements of a new permit issued by the Washington State Department of Ecology (WDOE) in January of 2007. The Western Washington Phase II Municipal Stormwater Permit requires the City to take actions like; educating the public and encouraging non-polluting behaviors, looking for illegal dumping and cross-connections, enforcing erosion and sediment control at construction sites, and using best practices for land management and stormwater system maintenance.
  • Water Clean-Up Plans - Total Maximum Daily Load (TMDL)
