Water Quality Resources

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.
