Water: Polluted Runoff

EPA Guidance for Controlling Nonpoint Source Pollution

Guidance for Federal Land Management in the Chesapeake Bay, May 2010

This guidance presents the most effective tools and practices to address nonpoint source pollution from federal land management activity in the Chesapeake Bay watershed. This guidance covers the following categories: agriculture, urban and suburban (including turf), forestry, riparian areas, decentralized wastewater treatment systems, and hydromodification. The same techniques can be used by states, local governments, conservation districts, watershed organizations, developers, farmers and citizens in the Chesapeake Bay watershed.

This guidance helps citizens and municipalities in urban areas protect bodies of water from polluted runoff that can result from everyday activities. These scientifically sound techniques are the best practices known today. The guidance also helps states to implement their nonpoint source control programs and helps municipalities implement their Phase II Storm Water Permit Programs.

Stormwater Management for Federal Facilities under Section 438 of the Energy Independence and Security Act, Dec. 2009

Stormwater runoff in urban areas is one of the leading sources of water pollution in the United States. Under the Section 438 of the Energy Independence and Security Act of 2007 (EISA), federal agencies are required to reduce stormwater runoff from federal development and redevelopment projects to protect water resources. Federal agencies can comply using a variety of stormwater management practices often referred to as "green infrastructure" or "low impact development" practices, including for example, reducing impervious surfaces, using vegetative practices, porous pavements, cisterns and green roofs. EPA worked closely with other federal agencies to develop technical guidance which provides background information, key definitions, case studies, and guidance on meeting the new requirements.

The primary goal of this guidance document is to provide technical assistance to states, territories, tribes and the public for managing hydromodification activities and reducing associated NPS pollution of surface and ground water. The document describes examples of the implementation of practices that can be used to reduce NPS pollution from activities associated with channelization and channel modification, dams, and streambank and shoreline erosion.
