Workflow

Overview

CaseMark's SWPPP skill automates the drafting of Stormwater Pollution Prevention Plans for construction projects subject to NPDES permitting under the Clean Water Act. It produces comprehensive, regulation-ready documents covering site characterization, BMP selection, inspection schedules, recordkeeping requirements, and operator certifications. The AI analyzes your project data against EPA CGP and state-specific requirements to generate a compliant plan in a fraction of the time manual drafting requires.

Drafting a compliant SWPPP is a time-intensive process that requires cross-referencing federal CGP requirements, state NPDES regulations, site-specific soil and drainage data, and extensive BMP design specifications. Environmental consultants and project managers often spend days assembling these documents, with the constant risk of omitting required sections or certification language that could trigger permit violations.

CaseMark automates SWPPP drafting by analyzing your project details, site characterization data, and regulatory requirements to produce a comprehensive, structured plan. The AI ensures every required section is addressed—from 40 CFR 122.22 certification language to receiving waters tables and BMP maintenance schedules—delivering a professional draft ready for review, customization, and submission.

How to hand this to Para

  1. 1. Send Para the files

    Email them, drop them in a Teams or Slack message, or upload them.

  2. 2. Para runs the Swppp skill

    It works from your files and checks its citations against the record.

  3. 3. The finished document comes back

    Para returns it where you asked, usually as a DOCX, and offers the next step.

Example request · email, Teams or Slack

Questions

Does this SWPPP meet EPA Construction General Permit requirements?

Yes. CaseMark drafts 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 sections, certification language, and BMP categories specified by the CGP.

Can it handle state-specific NPDES requirements?

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

What project information do I need to provide?

You'll need basic project details (name, location, acreage, timeline), operator identification, soil types and topography data, receiving water information, and any existing NPDES permits. Site plans and grading plans are helpful but optional.

How does CaseMark select appropriate BMPs?

CaseMark analyzes your site characterization data—soil types, slopes, drainage patterns, and proximity to receiving waters—to recommend appropriate erosion controls, sediment controls, and pollution prevention measures with installation timing and maintenance requirements.

Can I edit the SWPPP after it's generated?

Absolutely. CaseMark produces a fully editable document that you can customize, add site-specific details to, and refine before final submission. The output serves as a comprehensive draft ready for professional review and PE certification where required.

Is this suitable for projects disturbing less than one acre?

CaseMark's SWPPP skill is designed for construction projects disturbing one or more acres, which triggers NPDES permit coverage. However, smaller projects that are part of a larger common plan of development may also require a SWPPP, and CaseMark can draft those as well.
