Stormwater Permitting and AIM Program Management

Stormwater compliance is an ongoing program that extends well beyond permit coverage. Facilities are responsible for inspections, sampling, documentation, employee training, reporting, and maintaining a Stormwater Pollution Prevention Plan (SWPPP) that reflects current site conditions and operations.

Harrow Environmental provides comprehensive stormwater compliance services that help facilities establish, implement, and maintain effective stormwater programs. From permit coverage and SWPPP development to sampling, AIM program management, inspections, and long-term compliance support, we help clients keep their stormwater programs organized, current, and inspection ready.

Who Needs Stormwater Compliance Support?

Industrial facilities with stormwater permit coverage have ongoing compliance responsibilities throughout the life of the permit. Depending on permit requirements, facilities may need to conduct routine inspections, collect stormwater samples, complete employee training, submit reports, implement corrective actions, and maintain supporting documentation.

Harrow Environmental helps facilities manage these recurring compliance activities while keeping stormwater programs practical, organized, and aligned with facility operations.

Building and Maintaining Your Stormwater Program

An effective stormwater program requires more than permit coverage. It requires consistent implementation, documentation, and periodic updates as facility operations change.

Harrow Environmental supports every stage of stormwater compliance, including:

Permit applications and permit coverage
Stormwater Pollution Prevention Plans (SWPPPs)
Site maps and drainage evaluations
Pollutant source assessments
Stormwater control measures
Routine inspections
Employee training
AIM program management

As facilities grow and operations change, we help keep stormwater programs current, practical, and aligned with permit requirements.

Stormwater Monitoring and Sampling

Stormwater sampling is one of the most important components of permit compliance.

Knowing when to sample is just as important as knowing how to sample. Harrow Environmental helps facilities determine when permit sampling requirements are triggered, coordinate sampling events, collect stormwater samples, review laboratory results, and maintain the documentation needed to demonstrate compliance.

For facilities with recurring monitoring requirements, we provide practical support that simplifies sampling activities and keeps monitoring records organized throughout the permit cycle.

AIM Program Management

Under the EPA’s Multi-Sector General Permit (MSGP), benchmark exceedances may trigger Additional Implementation Measures (AIM), requiring facilities to evaluate stormwater control measures, implement corrective actions, and, when necessary, improve pollution prevention practices or install additional controls.

Harrow Environmental helps facilities manage AIM requirements before they become compliance challenges by:

Tracking benchmark monitoring results
Identifying AIM Level 1, 2, and 3 requirements
Evaluating stormwater control measures
Developing corrective action strategies
Updating SWPPPs and supporting documentation
Maintaining records that demonstrate compliance

Rather than reacting to benchmark exceedances, we help facilities understand their compliance obligations, document required actions, and maintain an effective stormwater program.

Documentation and Compliance Management

Stormwater compliance depends on maintaining complete and accurate documentation.

Inspection reports, sampling records, laboratory results, corrective actions, SWPPP revisions, employee training records, and annual reporting all become part of the facility’s compliance history.

Harrow Environmental helps clients organize and maintain these records throughout the life of the permit. Supporting documentation can be maintained within myEHSportal, providing facility personnel with centralized access to stormwater compliance records alongside other environmental, health, and safety documentation.

Supporting Long-Term Compliance

Stormwater programs evolve as facilities expand and operations change

Harrow Environmental provides ongoing support that helps facilities maintain compliance, prepare for inspections, reduce compliance gaps, and confidently manage stormwater programs year after year.

Frequently Asked Questions

Does every industrial facility need a stormwater permit?

Permit requirements depend on facility operations, industrial activities, and applicable federal or state regulations. Harrow Environmental helps determine whether permit coverage is required and identifies the compliance obligations that apply to each facility.

What is the AIM Program?

The AIM Program is part of the EPA’s Multi-Sector General Permit (MSGP). Benchmark exceedances may trigger additional compliance requirements, including evaluating stormwater controls, implementing corrective actions, and documenting required responses. Harrow Environmental helps facilities understand and manage those requirements.

How do I know when stormwater sampling is required?

Sampling requirements vary by permit and facility operations. Harrow Environmental helps facilities determine when sampling is required, coordinate monitoring events, review laboratory results, and maintain the documentation needed to demonstrate compliance.

Can Harrow Environmental collect stormwater samples?

Yes. Harrow Environmental provides stormwater sampling support, laboratory coordination, result evaluation, and compliance documentation to help satisfy permit monitoring requirements.

How does Harrow Environmental help maintain stormwater compliance?

We provide ongoing support that includes inspections, SWPPP updates, stormwater sampling, AIM program management, corrective action documentation, reporting support, employee training, and compliance recordkeeping to help facilities maintain effective stormwater programs.
