EPA Reaffirms Clean Water Permits Not Needed for Water Transfers

June 11, 2008
Rule clarifies that clean water permits should focus on water pollution, not water movement

The U.S. Environmental Protection Agency (EPA) has announced a rule to clarify that permits are not required for transfers of water from one body of water to another. Such transfers include routing water through tunnels, channels or natural stream courses for public water supplies, irrigation, power generation, flood control and environmental restoration.

"EPA's Water Transfer Rule gives communities greater certainty and makes clear they have the flexibility to protect water quality and promote the public good without going through a new federal permitting process," said Assistant Administrator for Water Benjamin H. Grumbles. "Clean water permits should focus on water pollution, not water movement. EPA is committed to working with our state, tribal and local partners to reduce environmental impacts associated with transfers and will continue to use all appropriate tools such as standards, best management practices and watershed plans."

Thousands of water transfers currently in place across the country are vital to the nation's water supply and infrastructure systems. Whether a permit is needed under the Clean Water Act's National Pollutant Discharge Elimination System (NPDES) has been an issue in numerous court cases in recent years. The final rule defines water transfers as an activity that conveys or connects waters of the U.S. without subjecting the transferred water to intervening industrial, municipal or commercial use. Pollutants introduced by the water transfer activity itself to the water being transferred would still require an NPDES permit under today's rule. Furthermore, this rule does not prevent states or tribes from using their own authorities to address water transfers, including the use of non-NPDES permits.

In 2004, the question of whether NPDES permits were necessary for water transfers went before the U.S. Supreme Court in South Florida Water Management District v. Miccosukee Tribe of Indians. The court did not rule directly on the issue, which left unresolved the uncertainty many felt about the need for an NPDES permit. EPA issued an interpretive statement in 2005 explaining that Congress intended water resource-management agencies and other state authorities to oversee water transfers, not the NPDES permitting program. This rulemaking codifies that position.

Over the last several years, EPA has been advancing water quality improvements related to water transfers and other hydrologic modifications through watershed planning and management measures. For example, last summer EPA issued the “National Management Measures to Control Nonpoint Source Pollution from Hydromodification” guidance that provides recommended best management practices for addressing the effects of changes in flow. The recently released “Handbook for Developing Watershed Plans to Restore and Protect Our Waters” can assist communities as they analyze water quality priorities in their watersheds and identify management measures to reduce causes of impairments.
