As the end of the year approaches, industrial facilities covered under the Texas Multi-Sector General Permit (MSGP) face one of their most important environmental compliance responsibilities: completing the Annual Comprehensive Site Compliance Inspection and Report (ACSCIR).

This annual inspection and reporting process is more than just a box to check — it’s a critical step in maintaining stormwater permit compliance, verifying the effectiveness of pollution prevention measures, and ensuring your facility continues to protect surrounding waterways from contamination.

At ESE Partners, we know the pressure that year-end brings for environmental managers, operations staff, and corporate EHS teams. That’s why our environmental professionals specialize in conducting ACSCIRs across Texas, helping industrial clients navigate every detail — from inspections and documentation to final reports and SWPPP updates — with confidence and accuracy.

 

What Is the ACSCIR?

The Annual Comprehensive Site Compliance Inspection and Report is a detailed evaluation required under the MSGP. It’s designed to verify that your facility’s stormwater controls and management practices remain compliant throughout the year.

During the ACSCIR, facilities must review all areas of the site exposed to stormwater, evaluate the effectiveness of their Best Management Practices (BMPs), identify any corrective actions that are needed, and ensure that their Stormwater Pollution Prevention Plan (SWPPP) remains current.

Each inspection results in a written report that documents findings, recommended improvements, and corrective actions, and it must be signed by an authorized company representative to be considered complete.

 

What the ACSCIR Includes

A properly completed ACSCIR typically includes:

  • A comprehensive site inspection of all stormwater-exposed areas, including storage yards, loading docks, waste collection points, and outfalls.
  • An evaluation of BMP effectiveness, assessing whether control measures such as containment berms, vegetative buffers, or good housekeeping practices are working as intended.
  • Documentation of corrective actions, detailing any issues identified and the steps required to resolve them.
  • Updates to the Stormwater Pollution Prevention Plan (SWPPP) to reflect operational or structural changes at the facility.
  • A written inspection report, signed and dated by an authorized representative and kept on file with the SWPPP.

By addressing these components thoroughly, facilities demonstrate due diligence and compliance with both TCEQ and EPA stormwater requirements.

 

Key 2025 MSGP Deadlines

It’s essential to stay on top of the reporting timeline to avoid non-compliance penalties. For the 2025 reporting year, key milestones include:

  • Benchmark and Hazardous Metals Monitoring Sampling Deadline: December 31, 2025
  • Inspection Completion Deadline: December 31, 2025
  • Report Finalization: Within 30 days of inspection completion
  • Retention: Maintain a copy of the ACSCIR on-site with your SWPPP for a minimum of three years

Missing these deadlines can result in enforcement actions, fines, or even permit violations — all of which can be avoided through proactive planning and professional support.
