When to Bring in Stormwater Consulting Support

You’ve had benchmark or NAL exceedances

Your SWPPP is outdated or hasn’t been reviewed by a QISP

Sampling, SMARTS reporting, or ERA deadlines are stressing your team

Your BMPs aren’t improving results, and you’re not sure why

You want one firm to manage compliance end-to-end

SWPPP Development & Updates

Build a defensible, permit-ready SWPPP tailored to your site.

Our QISP-led team prepares and updates Storm Water Pollution Prevention Plans that meet current California IGP requirements and reflect real site conditions.


SWPPP services include:

  • On-site facility inspections by a certified QISP

  • Identification of pollutant sources and exposure pathways

  • Site maps and pollutant source diagrams

  • Selection of appropriate BMPs and control measures

  • Updates to address permit revisions, TMDLs, or operational changes


Whether you need a new SWPPP or revisions to an existing plan, we ensure your documentation is accurate, current, and defensible.

Stormwater Monitoring & Sampling

Accurate sampling, complete documentation, and on-time reporting.

We manage the technical and administrative burden of stormwater monitoring so your team can focus on operations.


Monitoring services include:

  • Customized stormwater monitoring plans

  • Monthly visual observations

  • Qualifying storm event sampling

  • Laboratory coordination and data review

  • SMARTS uploads and annual report preparation

  • Rain event alerts and sampling readiness support


Our team ensures sampling is performed correctly and reported accurately; reducing compliance risk and data errors.

Exceedance Response Action (ERA) Support

Identify root causes, strengthen controls, and return to compliance.

If your facility exceeds permit benchmarks or Numeric Action Levels (NALs), Frog Environmental provides structured, permit-compliant ERA support.


ERA services include:

  • Level 1 and Level 2 ERA evaluations

  • Assessment of existing BMP performance

  • Identification of pollutant sources and failure points

  • Targeted BMP recommendations and corrective actions

  • Preparation and submittal of required ERA documentation


When non-structural BMPs are no longer sufficient, we also evaluate and implement engineered stormwater treatment systems to achieve compliance.

BMP Evaluation & Optimization

Improve results before enforcement escalates.

Not every exceedance requires treatment systems. We assess existing BMPs to determine whether performance can be improved through better placement, maintenance, or upgrades.


BMP services include:

  • Site-specific BMP evaluations

  • Performance optimization recommendations

  • Integration of source control, operational, and structural BMPs

  • Support during implementation and follow-up


Our goal is to reduce pollutant loading efficiently and cost-effectively, while maintaining permit compliance.
