Beginning in 2021 and continuing through 2022, the division led a stakeholder engagement process to gain feedback about potential changes to include in the COR900000 permit renewal. Following stakeholder feedback, the division released a draft COR900000 permit on March 10, 2022, with a public comment period that extended until August 5, 2022. The division has considered comments received during the public comment period and expects to issue the final permit, along with a response to comments, in the coming weeks or months. Here is a list of important changes to the new permit:
- Benchmarks and corrective actions
- PFAS requirements
- Coal tar sealant eligibility requirement

No Exposure Exclusion from CDPS Storm Water Permitting
"No Exposure" is an alternative to obtaining coverage under the COR900000 permit. In this context, "No Exposure" means that storm-resistant sheltering is in place to prevent exposure to rain, snow, snowmelt and/or runoff. To be eligible for this exclusion, you must apply for and obtain division approval through the issuance of a certification. Part G of the application contains a self-certifying checklist for you to assess whether your facility meets conditions of "No Exposure."
