Colorado to Revise 303(d) List of Impaired Waters

The state 303(d) list of impaired waters is an important part of Colorado’s water quality control program, but is often overlooked by stakeholders. Because an impairment listing on the 303(d) list is the first step toward development of a Total Maximum Daily Load (TMDL), which can in turn affect discharge permit requirements, it is important for stakeholders to engage in the public process related to development of the 303(d) list.

The 2018 303(d) list process begins in July and culminates in a rulemaking hearing in December, with the deadline to establish party status in September.

WWE’s Noah Greenberg would be pleased to speak with anyone who is interested in learning more about effectively participating in this process.
