On February 29, 2024, the Colorado Department of Public Health and Safety (CDPHE) withdrew its prior amended version to the Industrial Stormwater General Permit for Non-Extractive Industries, COR900000 — even before its effective date this summer (July 1, 2024). Subsequently on March 14, 2024, CDPHE issued a public notice of the new draft modifications for its proposed changes. Importantly, the deadline for the public’s participation during this comment period is on Monday, April 15, 2024.
