SWPPP Inspection Forms, Reports & Checklists
Routine and post-storm-event inspections are a core SWPPP requirement under both the federal CGP and most state permits. The forms below cover the two most commonly requested inspection documents — a federal reporting template and a state-level pre-inspection checklist — gathered here so you don't have to dig through the full permit pages to find them. See the state sections below for additional state-specific inspection requirements. For guidance on inspection frequency, what to check on-site, and how to document findings, see our guide on how to conduct a stormwater inspection.

Notice of Intent (NOI)
Coverage under a construction stormwater permit starts with filing a Notice of Intent (NOI) — the submission process differs by jurisdiction, so use the links below to file directly with the relevant permitting authority.
Federal (EPA)
File an NOI, NOT, or Low Erosivity Waiver under the federal CGP.
California (SWRCB / SMARTS)

State Resources
Arizona (ADEQ)
State permit and templates for Arizona construction stormwater.
California (SWRCB / SMARTS)
California's construction permit and SWPPP checklist.
California doesn't publish a fill-in SWPPP template — the CGP and Industrial General Permit both require your SWPPP to be prepared by a Qualified SWPPP Developer (QSD) and submitted through SMARTS.
Facilities under California's Industrial General Permit also owe an Annual Comprehensive Site Compliance Evaluation (ACSCE) — a yearly review of site conditions, BMP performance, and SWPPP effectiveness, conducted by a Qualified Industrial Stormwater Practitioner (QISP). Findings must be documented and used to update the SWPPP where BMPs are falling short.
Texas (TCEQ)
TXR150000 permit and core forms for Texas construction sites.
Colorado (CDPHE)
Permit landing page and compliance guidance for Colorado.
