EIM ME AND NAn RESOURCES REPRESENTATIVE OUTFALL STATUS (ROS)
REQUEST FORM
If a facility is required to sample multiple discharge locations with very similar-stormwater discharges, the
permittee may petition the Director for Representative Outfall,Status (ROS). DWQ may grant Representative
Outfall Status if stormwater discharges from a single outfall are representative,of discharges from multiple
outfalls. Approved ROS will reduce the number of outfalls where analytical sampling requirements apply.
If Representative Outfall Status is granted,,ALL outfalls are still subject,to the qualitative monitoring
requirements of the facility's permit—unless otherwise allowed by the permit (such as NCG020000) and DWQ
approval. The approval letter from DWQ must be,kept on site with the facility's Stormwater Pollution
Prevention Plan. The facility must notify DWQ in writing if any changes affect representative status.
For questions, please contact the DWQ Regional Office for your area (see page 3).
