The Department of Environmental Quality proposed the adoption of amended and new regulations to Surface Water Quality Standards to comply with §303(c) of the CWA, which requires all states to, where appropriate, adopt and revise water quality standards at least once every three years. The rulemaking amends, repeals, and establishes new sections in Article 1, such as definitions; the applicability of the water quality standards; designated uses; antidegradation implementation procedures; narrative water quality standards; new effluent dependent waters; numeric water quality criteria for total ammonia; site-specific standards; numeric water quality standards; and surface waters and designated uses. http://www.azsos.gov/public_services/Register/2008/14/proposed.pdf pp. 959-1096.
