This checklist is a starting point. Check each item against your current permit and your agency's standards before relying on it. Based on the CDPHE Water Quality Control Division General Permit COR400000 (renewed 2024) for stormwater discharges associated with construction activities. Colorado calls the SWPPP a Stormwater Management Plan (SWMP). Check each template against the current permit and your local requirements before relying on it.
