Resources and Guidance for the Construction Stormwater General Permit

Discharge Monitoring Report (DMR) – Basic Information

A change under the 2010 general permit is that Permittees must submit monthly discharge monitoring reports (DMRs) electronically using Ecology’s secure online system, WAWebDMR unless you have been approved for a waiver. To sign up for WAWebDMR go to: http://www.ecy.wa.gov/programs/wq/permits/paris/webdmr.html. The waiver request form is available at: http://www.ecy.wa.gov/programs/wq/stormwater/construction/index.html. If you have questions, contact Charles Gilman at charles.gilman@ecy.wa.gov, or 360-407-6437.
Permittees are required to submit a Discharge Monitoring Report (DMR) each reporting period (each month), even if there is no sampling or no discharge during the reporting period and/or of there is no construction activity.
Permittees must take samples from all discharge points where stormwater (or authorized non-stormwater such as de-watering water) flows off-site. For more information on authorized and prohibited discharges, please refer to Special Condition S1.C and D in the Construction Stormwater General Permit.
Permittees who obtain a waiver to submit “paper” DMRs, need to make copies of the blank DMR form they were mailed at the time of permit coverage, and use a copy of that form for reporting. Permittees may request a new blank DMR form, please contact your permit administrator. Mail your completed DMRs to:
