Water Quality Standards, 303(d) Lists, TMDL’s
What are they?
Why and how are they important to MS4s?
Title 3 of our nation’s Clean Water Act sets out how states are to establish water quality goals, determine whether their waters meet goals and develop recovery plans for waters impaired by pollutants. Waters found not to meet goals are reported to EPA on a list required by Section 303(d) of the Act, so they’re commonly referred to as “303(d) listed waters.” Regulated dischargers to listed waters, including Municipal Separate Storm Sewer Systems, are required by their NPDES permits to control discharges so waters can recover.
Where waters are impaired by pollutants, recovery plans titled “Total Maximum Daily Loads” or “TMDLs” allocate pollutant loading among contributing sources and may establish other monitoring and control requirements. Some MS4 discharges are subject to requirements established through TMDLs. We’ll see some examples.
Public participation opportunities are offered in each step of water quality planning. National Stormwater Center encourages all stakeholders, and particularly MS4s, to get involved. This training is designed to give MS4 staff the basics they’ll need to become effectively involved in setting goals for local waters, assessing whether the quality of those waters meets goals and developing recovery plans for waters that don’t.
We’ll discuss these subjects:
- Water quality standards, use classification, criteria, antidegradation
- Monitoring and assessment
- 303(d) listing and implications for MS4 permits
- Pollutants, water quality models, TMDLs, waste load allocation, load allocation, margin of safety, seasonal variation, reasonable assurance, implementation plans
- Why and how MS4s should be involved
We hope to see you there!
