14-WA-b NPDES Permit

Permit Overview

The Clean Water Act (CWA) required the Environmental Protection Agency (EPA) to establish the National Pollutant Discharge Elimination System (NPDES) program to require facilities discharging from a point source into waters of the United States to obtain discharge permits. The Washington State Department of Ecology (WSDE) administers the NPDES permitting program in Washington.

The NPDES permit describes:

  • What the discharger must do to protect water quality;
  • The types of monitoring and reporting the discharger must perform; and
  • Limits on how much pollution can be discharged to maintain water quality.

No pollutants may be discharged to the waters of Washington from any point source, except as authorized by an Individual Permit issued pursuant to WAC 173-220, or as authorized through coverage under a General Permit pursuant to WAC 173-226. WAC 173-226-020 and WAC 173-220-020. A project may qualify for either an Individual NPDES Permit or for a General NPDES Permit. An individual permit is written for a specific discharge at a specific location. An individual permit is highly tailored to regulate the pollutants in the discharge.

A general permit is for a group of similar dischargers at diverse locations. Once issued, a general permit may cover many facilities quickly and efficiently. A general permit is appropriate when the characteristics of the discharge are similar and a standard set of permit requirements can effectively provide environmental protection. WSDE collects information about typical pollutants and discharge conditions from the targeted group and sets permit requirements to regulate a generalized set of pollutants and discharges.

    Flowchart Narrative

    14-WA-b.1 – Does the Discharge Qualify for a General Permit?

    General Permits may be written to cover the following within a described area:

    • Storm water sources; or
    • Categories of dischargers that meet all of the following requirements:
    1. Involve the same or substantially similar types of operations;
    2. Discharge the same or substantially similar types of wastes;
    3. Require the same or substantially similar effluent limitations or operating conditions, and require similar monitoring; and
    4. In the opinion of the WSDE, pollutants are more appropriately controlled under a General Permit than under Individual Permits. WAC 173-226-050(3).

    14-WA-b.2 to 14-WA-b.3 – Application for NPDES Permit and Associated Documents

    Individual Permit

    Any person proposing to commence a discharge of pollutants to surface waters of the state must submit an application with WSDE on a prescribed form no less than 180 days in advance of the date the discharge will commence, or in sufficient time prior to commencement of the discharge to insure compliance with the requirements of section 306 FWPCA and any other applicable water quality standards or effluent standards and limitations. WAC 173-220-040(2).

    General Permit

    The developer must submit an application to WSDE to be considered for the development of a general permit. WAC 173-226-060(1).

    14-WA-b.4 – Provide Notice of Receipt of Application

    Individual Permit

    WSDE will provide notice to the developer of receipt of application along with an estimate time for completion of the permit.

    General Permit

    WSDE will respond to the application within 90 days of receipt. WAC 173-226-060.

    14-WA-b.5 – Review Application Materials for Completeness

    WSDE must review application materials for completeness.

    14-WA-b.6 to 14-WA-b.7 – Is the Application Complete?

    WSDE may request additional information from the developer to complete the application.

    14-WA-b.8 – Evaluate Discharge for Pollutants

    WSDE will evaluate discharges for pollutants in order to determine necessary effluent limits, Best Management Practices, special conditions, and monitoring requirements.

    14-WA-b.9 – Develop Effluent Limits, Best Management Practices, Special Conditions, and Monitoring Requirements

    Individual Permit

    Any permit issued by WSDE must apply and insure compliance with all of the following, whenever applicable.

Effluent limitations must not be less stringent than those based on the treatment facility design efficiency contained in approved engineering plans and reports or approved revisions. The effluent limitations must reflect any seasonal variation in industrial loading. WAC 173-220-130.

    WSDE may attach terms and conditions to any Individual Permit. WAC 173-220-150(1).

    General Permit

    Any General Permit issued by WSDE must apply and insure compliance with all of the following, whenever applicable:

WAC 173-226-190(1).

    The terms and conditions of a General Permit, as they apply to an individual discharger, are appealable within 30 days of the effective date of coverage of that discharger. This appeal is limited to that individual discharger. WAC 173-226-190(2). The appeal of General Permit coverage of an individual discharger does not affect any other dischargers covered under the General Permit. If the terms and conditions of a General Permit are found to be inapplicable to any individual discharger(s), the matter must be remanded to WSDE for consideration of issuance of an Individual Permit.
