Over 10 years, from 2017 to 2027, CDPHE will develop or revise the following water quality standards:
-
Nutrients (total nitrogen, total phosphorus, and chlorophyll a).
Our plan allows extra time for us to address complicated criteria development. A key point in the plan is our focus on stakeholder input about the complexity of treatment if the commission adopts new or revised standards for multiple substances. We are committed to an extensive stakeholder process including quarterly workgroup meetings.
