Stormwater pollution is a major concern for industrial facilities across Los Angeles. If your site discharges stormwater into state waterways, you’re likely subject to the Industrial General Permit (IGP). This permit ensures facilities manage their runoff responsibly and follow strict environmental standards.
At SoCal Stormwater Solutions, we help clients navigate IGP compliance — from stormwater BMPs to QISP certification and SWPPP best management practices — so your site stays on track and avoids costly violations.
What Is the Industrial General Permit (IGP)?
The IGP is a statewide permit issued by the California State Water Resources Control Board. It requires industrial facilities to:
- Develop and maintain a Stormwater Pollution Prevention Plan (SWPPP)
- Implement Best Management Practices (BMPs)
- Perform ongoing monitoring and reporting
- Designate a Qualified Industrial Stormwater Practitioner (QISP), when required
If your business falls under specific SIC codes, you must enroll in the IGP via the SMARTS permitting system and begin tracking your discharge activity regularly.
What Are Stormwater BMPs for Industrial Sites?
Stormwater BMPs (Best Management Practices) are preventive strategies that reduce pollutants in stormwater runoff. For industrial facilities, BMPs may include:
- Covered storage for materials
- Spill response protocols
- Routine site inspections
- Secondary containment systems
These measures form a key part of your site’s SWPPP and help demonstrate proactive stormwater runoff control.

Do You Need QISP Certification?
Under the IGP, some facilities must designate a QISP (Qualified Industrial Stormwater Practitioner) to manage compliance. A QISP ensures your site follows approved sampling procedures, documentation, and corrective actions.
Not sure if you need one? Our team can guide you through Tier I and Tier II designations and help connect you with certified professionals.
