- The customer completes an Industrial Wastewater Discharge Permit Application
and submits it to DSRSD.
- DSRSD reviews the permit application and conducts an industrial
- DSRSD issues an Industrial Wastewater Discharge Permit to the customer.
- The customer and DSRSD begin implementing permit provisions, including monitoring industrial waste and submitting reports.
All industries are asked to complete an Industrial Wastewater Discharge Permit Application to determine whether they are required to participate in the District’s Pretreatment Program. Send the completed application to:
Dublin San Ramon Services District
Environmental Compliance Division
7399 Johnson Drive
Pleasanton, CA 94588
Industrial Wastewater Inspection
After the permit application has been received and reviewed, DSRSD will schedule an industrial waste inspection at the customer’s facility. An inspection consists of a facility tour and a separate interview to discuss the customer’s application and its waste-generating processes, water consumption, wastewater composition, and quantities of wastewater flow.
A tour of the plant facilities completes the inspection process. Operations that contribute wastes to the sewer system, chemical storage areas, and pretreatment facilities must all be inspected. An important part of the tour is identifying an industrial waste sampling location that will be used both for self-monitoring and Pretreatment Program monitoring. It is the customer’s responsibility to provide an adequate sampling location in accordance with District requirements.
Discharge permit conditions will be based on the inspector's report and the permit application.
Industrial Wastewater Discharge Permit
The customer’s Industrial Wastewater Discharge Permit defines maximum concentrations of specific substances allowed in its wastewater discharge. To document compliance, the customer may be asked to keep operation and maintenance logs, monitor discharge quality through periodic sampling and analysis, file compliance certification reports, and develop spill response plans. Some industries may be required to pretreat their wastes in order to comply with these limitations.
The DSRSD Pretreatment Program establishes local discharge limits that apply to all permits. For some industries, the EPA may issue national industrial waste categorical standards that could be more stringent than those imposed by the District's Pretreatment Program. In these cases, as required by EPA, the more stringent standards would become part of the customer’s discharge permit.
Businesses participating in the Pretreatment Program pay fees that reflect the staff effort involved in permitting, monitoring, and lab analyses. Other fees may apply as a result of enforcement actions.
