After a project is grandfathered into coverage under the new CGP at risk level 1 (type 1), can the State Water Board or Regional Water Board change that projects risk level?
Yes, the Regional Water Boards have the authority to require a risk determination be performed on grandfathered projects that have a history of non-compliance with the 99-08-DWQ, 99-06-DWQ, and 2003-0007-DWQ Permits, or where the project poses a significant threat to water quality without the implementation of the additional Risk Level 2 or 3 requirements.
