Stormwater Municipal Permit Implementation Assistance Grants

Ecology provides assistance to NPDES Stormwater Municipal Permitees though two biennial grant programs, Capacity Grants and Grants of Regional or Statewide Significance (GROSS). These programs provide funding for activities, technical resources, and equipment that will help local governments implement the requirements of the Eastern and Western Washington Municipal Stormwater permits.

Stormwater Capacity Grants are non-competitive grants that are awarded directly to each municipality. GROSS grants benefit multiple permittees across a region or the state. To receive funding, applicants must submit a project application which is reviewed and prioritized for funding by Ecology staff.
