Agricultural Conservation Flexibility Act of 2014

Agricultural Conservation Flexibility Act of 2014 - Amends the Federal Water Pollution Control Act (commonly known as the Clean Water Act) to require the U.S. Army Corps of Engineers and the Environmental Protection Agency (EPA) to withdraw the interpretive rule issued on March 25, 2014, entitled, "U.S. Environmental Protection Agency and U.S. Department of the Army Interpretive Rule Regarding the Applicability of the Clean Water Act Section 404(f)(1)(A)."

Prohibits the Corps and the EPA from using the interpretive rule, or any substantially similar rule or guidance, as the basis for any rulemaking, decision, or action regarding the scope or enforcement of the Clean Water Act. Provides that the use of rule or a substantially similar rule or guidance as the basis for any rule, decision, or action is grounds for vacating the rule, decision, or action.

Requires soil and water conservation practices to be treated as normal farming, silviculture, and ranching activities under permits for non-prohibited discharges of dredged or fill material. Prohibits such practices from being treated as a new use of an area of navigable waters, an impairment of the flow or circulation of navigable waters, or a reduction in the reach of such waters under those permits.

Applies this Act to activities occurring on or after March 25, 2014.
