How Does the MSGP Renewal Affect You?

Industrial stormwater management in Texas is regulated by the Texas Commission on Environmental Quality (TCEQ) under the Texas Pollutant Discharge Elimination System (TPDES) Multi-Sector General Permit (MSGP) TXR050000.

Permitting and the 2026 MSGP Renewal

• Permit Status: The MSGP TXR050000 expired on August 14, 2026, triggering a 90-day grace period for existing operators to file renewal applications and update authorizations. All permit holders are required to renew by November 11, 2026.
• Compliance Paths:
• Notice of Intent (NOI): Required for active industrial exposure, necessitating a written Stormwater Pollution Prevention Plan (SWPPP), structural site controls, regular inspections, and certified laboratory sampling.
• No Exposure Certification (NEC): Applies exclusively to facilities with zero industrial materials or activities exposed to stormwater indoors, carrying lower administrative fees.
• Filing Portal: Submissions and renewals are handled online through the TCEQ STEERS/ePermits portal, requiring active “Signer” and “Preparer” accounts.

Storm Water Pollution Prevention Plan Development & Updates

• Plan Requirements: A compliant SWPPP must feature detailed site maps (elevations, drainage patterns, outfall locations), identification of potential pollutant sources, and facility-specific Best Management Practices (BMPs).
• 2026 Updates: Updated plans must account for newly adopted 2022 NAICS codes, tighter pollutant benchmark parameters, and digital recordkeeping options.

Inspections & Monitoring

• Routine Inspections: Facilities must maintain a consistent calendar for monthly or quarterly visual monitoring and facility walkthroughs to check the integrity of controls and containment areas.
• Corrective Actions: Any failed visual indicator or benchmark exceedance triggers formal tracking, documentation, and operational adjustments.

Sampling & Reporting

• Analytical Sampling: Annual analytical grab sampling must be performed by partnering with certified environmental laboratories, though benchmark monitoring schedules may shift during active permit transitions.
• Reporting Deadlines: Annual benchmark analysis results and Discharge Monitoring Reports (DMRs) are submitted electronically via NetDMR/STEERS, with standard annual deadlines on March 31.

Depending on your sector, people are required to get benchmark sampling and routine inspections. Inspections can be required quarterly and semiannually. Benchmark levels have been lowered across many sectors with the new permit.
