Wednesday, Congressman Scott Tipton (R-CO) questioned (EPA) Deputy Administrator Bob Perciasepe during a House Small Business Committee hearing on the EPA’s controversial new rule to redefine waters of the United States under the Clean Water Act. During the hearing, Tipton submitted a letter to the record from the Waters Advocacy Coalition, representing various industries, sectors and interests that would be affected by the waters of the U.S. rule. The letter in part objects to the insufficient analysis offered by the EPA on the impacts the rule will have. The letter’s 39 signers, include the American Farm Bureau Federation, the American Gas Association, the Foundation for Environmental and Economic Progress, the National Association of Homebuilders, the National Pork Producers Council and many others. Tipton’s questions focused on getting clarification on what the EPA’s redefinition of waters of the United States actually encompasses. Tipton says the responses were broad and did not shine additional light on what surface waters would not be impacted under the new rule. You can see video of the exchange below.
