Discharge Requests

Questions regarding discharges to the storm and sanitary sewer? 

If you have a question regarding disposal of stormwater, wastewater or other material to the storm or sanitary sewer you can get guidance and approval from the Environmental Services Source Control Division (SCD). Some discharges are allowed without restrictions, while others may not be allowed or require a permit or authorization from the SCD. If a discharge requires an authorization, you may need to fill out a batch discharge request form to obtain pre-approval. This may result in the requirement to sample and test the material or implement Best Management Practices as part of the approval. The SCD can provide you with all the information you need to appropriately dispose of materials and comply with federal, state, and local regulations.
