6 Arizona’s 2006/2008 Impaired Waters Arizona’s 303(d) Impaired Waters List consists of two sections: the first section consists of ADEQ 303(d) listings, while the second consists of EPA 303(d) listings.

*Assessment Categories:

Category 5 – Impaired surface waters where a Total Maximum Daily Load (TMDL) analysis is required.

Category 4 – At least one designated use is impaired or threatened but development of a TMDL is not needed (at this time). Note that these assessment units are considered impaired under permit requirements. Three subcategories exist in Arizona:

4A – The TMDL has been completed, is being implemented, and appears to be sufficient; 4B – Alternative pollution control requirements or actions are expected to result in the attainment of water quality standards; 4C – The impairment is caused by pollution but not a pollutant; or 4N – Impairment is caused solely due to natural conditions (no human contribution).

(Further information is provided in the Surface Water Assessment Methods and Technical Support document.)
