Discharge Monitoring Reports

  • Permittees are required to submit a Discharge Monitoring Report (DMR) each reporting period (each quarter), even if there is no sampling or no discharge during the reporting period.

  • For Permittees that receive permit coverage after January 2, 2015, the first reporting period is the first full quarter following the effective date of permit coverage. For example, if a facility obtains permit coverage May 15, 2015, the first reporting period would be the 3rd Quarter 2015 (July 1 – Sept 30), with the DMR due no later than November 15, 2015.

  • DMRs and other written reports must be submitted electronically using Ecology’s Water Quality Permitting Portal – Discharge Monitoring Report (DMR) application, unless a waiver from electronic reporting has been granted (e.g., if a Permittee does not have broadband internet access).
  • If a waiver has been granted, reports must be postmarked or delivered to the following address by the due date:
    Department of Ecology
    Water Quality Program - Industrial Stormwater
    PO Box 47696
    Olympia, WA 98504-7696
  • For facilities discharging to Puget Sound Sediment Cleanup Sites, Solids Monitoring Report (SMR)forms, identified as a single sample DMR type, are included with the quarterly DMR forms on the Portal.
