With the exception of five states and the District of Columbia the states are responsible for managing water quality. (EPA currently is the regulatory authority for stormwater permitting in the states of Alaska, Idaho, New Hampshire, Massachusetts, and New Mexico.)  This includes the issuance of permits for stormwater discharges related to construction activities, development and administration of Total Maximum Daily Loads (TMDLs) and other water quality related issues.  Modifications to or work within the boundaries of water courses may be regulated by the U.S. Army Corps of Engineers and/or the state.  For this reason, investigations of water related issues should begin with the state regulatory agencies. State agency links may be accessed at the Association of State and Interstate Water Pollution Control Administrators state agencies website. Links to state transportation agencies' environmental program offices may be accessed from the state agencies link on this website.   

State Water Quality Programs and Related Information

For additional information, contact the state water quality regulatory programs.

• Caltrans Stormwater Site. This site has links to numerous detailed publications, manuals and guidance documents.  While the information is specific to California in some respects they are valuable as reference materials as well.
• Florida Stormwater Association. This is an example of an independent organization formed to serve professionals in stormwater management with a focus on stormwater utilities.
• Florida Department of Environmental Protection, Water Resources Management site. Florida has an extensive program for the protection of the states water resources.  This site has links to the various programs an can be a valuable reference for other states.
• Georgia Department of Natural Resources, Environmental Protection Division, Watershed Protection Branch. Georgia has a comprehensive program for watershed management and an erosion and sediment control manual.
• North Carolina Department of Environment and Natural Resources, Division of Water Quality. North Carolina has a very well organized web page for water quality that is easily navigated.
• New York State Department of Environmental Conservation, Construction Stormwater Information. This site provides tools and sources of technical information related to the General Permit for Construction Activities and useful for the design of stormwater management practices.
