Description: This report presents a summary of the law, describing the essence of the statute without discussing its implementation.

Description: Section 401 of the Clean Water Act requires that an applicant for a federal license or permit provide a certification that any discharges from the facility will comply with the Act, including water quality standard requirements. Disputes have arisen over the states' exercise of authority under Section 401. Until recently, much of the debate over the Section 401 certification issue has been between states and hydropower interests. A 1994 Supreme Court decision which upheld the states' authority in this area dismayed development and hydroelectric power interest groups. The Court revisited these issues in a 2006 ruling that unanimously upheld the states' authority to condition hydropower licenses. The dispute between states and industry groups about Section 401 authority has been a legislative issue on several occasions, but Congress has not responded by modifying the provision's scope. In addition, there has been interest in clarifying whether Section 401 certification applies to nonpoint source discharges, such as rainfall runoff, as well as point source discharges from pipes or ditches.

Description: This report describes the several types of waste streams that cruise ships may discharge and emit. It identifies the complex body of international and domestic laws that address pollution from cruise ships. It then describes federal and state legislative activity concerning cruise ships in Alaskan waters and activities in a few other states, as well as current industry initiatives to manage cruise ship pollution.

Description: This report discusses the regulation of stormwater drainage. Stormwater discharge systems are the pipes and sewer lines that carry rainwater or snow melt, but not domestic sanitary wastes, away from urban areas and commercial and industrial facilities. For many years the focus of the nation's water quality programs was on controlling pollutants associated with industrial process wastewaters and municipal sewage discharges.
