When is a Wastewater Discharge Permit required?
Businesses and activities that require a discharge permit include any industrial facility requiring regulation under federal law, and facilities the City believes warrant periodic inspection and monitoring to prevent discharge of problem pollutants into the sewer system.

Examples of such facilities include:

• product manufacturing
• commercial food preparation
• photographic image processing
• groundwater remediation

Permits typically consist of sampling and monitoring requirements, and/or compliance with best management practices (BMPs).
