The Port's Stormwater Program
The stormwater management program is a major element of the Port of Olympia's commitment to preventing, reducing and eliminating the discharge of pollutants into Puget Sound. We work closely with port tenants and the Washington Department of Ecology to minimize the potential for pollutants to enter Puget Sound from stormwater runoff flowing off impervious surfaces on port properties.
The federal and state water quality laws require a permit for discharges of rain water and snow melt into surface water (lakes, rivers, ponds, streams, inland waters and salt waters). The purpose of a permit is to control the quantity and/or quality of the water discharged to protect surface water and groundwater. The Port’s properties are covered by two separate permits. The Port of Olympia’s industrial marine terminal is covered by the industrial stormwater general permit, issued by Washington’s Department of Ecology as part of the National Pollutant Discharge Elimination System (NPDES). Other areas of the Port’s property are covered by a municipal general stormwater permit, also issued by the Department of Ecology as part of the NPDES program.
The Port's Stormwater Treatment Facility located on the Marine Terminal
The goal under the permits is to implement and maintain best management practices that identify, reduce, eliminate and/or prevent the discharge of specific stormwater pollutants into surface water. The Port accomplishes these goals by complying with its Stormwater Management Program (SWMP, for the municipal general permit) and Stormwater Pollution Prevention Plan (SWPPP, for the industrial general permit). The Port’s stormwater compliance program is implemented by the Port’s Engineering Department, in coordination with the Port’s seaport, real estate, and Swantown Marina divisions, as well as with building and grounds maintenance crews, and Port tenants. In compliance with applicable permit requirements, the Port’s SWMP and SWPPP contain the following components:
Best management practices to control potential pollutants
Spill prevention and control
Construction site stormwater runoff control
Illicit discharge detection and elimination
Pollution prevention / good housekeeping for municipal operations
Post-construction stormwater management for new development and redevelopment
Public education and outreach
The Port continually strives to improve and upgrade stormwater management practices and infrastructure on our facilities. To comment on the Port's Stormwater Management Program, send the Port an email.
Both the industrial and municipal permits are under the supervision of the Department of Ecology.
