Workflow

Overview

CaseMark's SWPPP drafting tool uses AI to generate comprehensive Stormwater Pollution Prevention Plans for construction projects disturbing one or more acres. The tool produces fully structured documents covering site characterization, BMP selection, inspection schedules, and operator certifications aligned with 40 CFR Part 122, the EPA Construction General Permit, and state NPDES requirements.

Drafting a compliant SWPPP is a time-intensive process that requires cross-referencing federal and state regulations, characterizing site conditions, selecting appropriate BMPs, and ensuring every required element is included. Missing a single certification block or receiving water classification can delay permit approval and expose operators to enforcement actions.

CaseMark automates the heavy lifting of SWPPP preparation by analyzing your project details, site data, and permit information to produce a complete, regulation-aligned draft. The AI ensures every required section—from 40 CFR 122.22 certification language to BMP design specifications—is included and properly structured, letting environmental professionals focus on site-specific review rather than document assembly.

How it works

1. Upload your project details, site characterization data, and existing permits
2. AI analyzes site conditions, receiving waters, and regulatory requirements to draft a compliant SWPPP
3. Review and customize BMP selections, inspection schedules, and certification language
4. Export the finalized SWPPP in your preferred format (DOCX, PDF)

Streamline multi-state compliance by adapting to jurisdiction-specific NPDES and MS4 requirements

Questions

Does this SWPPP comply with the EPA Construction General Permit?

Yes. CaseMark generates SWPPPs that follow the structure and content requirements of the EPA CGP, 40 CFR Part 122, and applicable state NPDES programs. The output includes all required certification language, BMP categories, and inspection frameworks mandated by federal regulations.

Can I customize the BMP selections for my specific site conditions?

Absolutely. CaseMark drafts BMP recommendations based on your site characterization data, including soil types, topography, and receiving water sensitivity. You can review and modify every BMP selection, design specification, and maintenance requirement before finalizing.

Does it handle state-specific NPDES requirements?

CaseMark incorporates state-level CGP and MS4 requirements when you provide your existing permits and state-specific documentation. The AI adapts certification language, PE seal requirements, and additional BMP standards to match your jurisdiction.

What if my project involves endangered species habitat or historic properties?

CaseMark includes an endangered species and historic preservation eligibility determination section in every SWPPP. The AI flags environmental features you identify and generates the appropriate screening language required by the CGP.

How long does it take to generate a complete SWPPP?

CaseMark typically generates a comprehensive draft SWPPP in approximately 12 minutes, compared to the days or weeks it can take to draft one manually. You can then review, refine, and export the final document immediately.

Is the output ready for submission to regulators?

CaseMark produces a professional, regulation-aligned draft that covers all required SWPPP elements. However, you should have a qualified professional review the document, add any required PE seal, and verify site-specific details before formal submission.
