Swppp

Overview

CaseMark's SWPPP skill uses AI to draft comprehensive Stormwater Pollution Prevention Plans for construction projects requiring NPDES permit coverage. It transforms your project details, site characterization data, and existing permits into a fully structured SWPPP with certification language, BMP selections, receiving waters analysis, and inspection schedules—all aligned with 40 CFR Part 122 and EPA CGP requirements.

Drafting a compliant SWPPP is a time-intensive process that requires cross-referencing federal and state regulations, characterizing site conditions, selecting and specifying appropriate BMPs, and ensuring every required element—from certification language to inspection schedules—is properly documented. Missing a single requirement can result in permit violations, enforcement actions, and costly project delays.

CaseMark automates the heavy lifting of SWPPP preparation by analyzing your project data against EPA CGP and NPDES requirements to produce a comprehensive, regulation-ready plan. The AI structures every required section—from cover page certifications to BMP specifications and receiving waters tables—so environmental professionals can focus on engineering judgment rather than document assembly.

How it works

  1. 1. Upload your project details, site characterization data, and any existing permits or site plans

  2. 2. AI analyzes site conditions, receiving waters, and regulatory requirements to draft a comprehensive SWPPP

  3. 3. Review and customize BMP selections, inspection schedules, and compliance language

  4. 4. Export the finished SWPPP in your preferred format (DOCX, PDF) ready for operator certification

Questions

Does the SWPPP meet EPA Construction General Permit requirements?

Yes. CaseMark generates SWPPPs structured to comply with 40 CFR Part 122, the EPA Construction General Permit (CGP), and applicable state NPDES requirements. The output includes all required certification language, BMP categories, and inspection frameworks mandated by the Clean Water Act.

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, installation timing, design specification, and maintenance requirement before finalizing.

Does it handle projects in states with additional NPDES requirements?

CaseMark incorporates both federal CGP requirements and flags areas where state-specific NPDES provisions may apply, such as additional BMP standards, PE seal requirements, or MS4 coordination. You can upload state-specific permit documents to further tailor the output.

What size construction projects is this designed for?

CaseMark's SWPPP skill is designed for construction projects disturbing one or more acres, which is the federal threshold triggering NPDES stormwater permit coverage. It scales from single-acre residential developments to large-scale commercial and infrastructure projects.

How does CaseMark handle the receiving waters analysis?

CaseMark generates a structured receiving waters table identifying all water bodies receiving discharge, their classification, 303(d) impairment status, TMDL applicability, and distance from the project site. This analysis is built from the site characterization data you provide.

Can I update the SWPPP as site conditions change during construction?

Yes. CaseMark allows you to regenerate or revise sections of the SWPPP as project phases advance, site conditions change, or new BMPs are needed. This supports the CGP requirement to keep the SWPPP current throughout the life of the project.
