EPA is issuing draft Nonpoint Source Program and Grants Guidelines for States and Territories (PDF) (59 pp, 1.4MB, About PDF). These guidelines are available for review and comment by states and territories, as well as other interested stakeholders. Please submit comments to EPA at 319grants@epa.gov by COB Dec. 21, 2012 (extended from Dec. 7).

The 1987 amendments to the Clean Water Act (CWA) established the Section 319 Nonpoint Source Management Program. Section 319 addresses the need for greater federal leadership to help focus state and local nonpoint source efforts. Under Section 319, states, territories and tribes receive grant money that supports a wide variety of activities including technical assistance, financial assistance, education, training, technology transfer, demonstration projects and monitoring to assess the success of specific nonpoint source implementation projects.

 EPA has released guidance on the key components of an effective state nonpoint source (NPS) management program (PDF) (7 pp, 73K, About PDF). This guidance is an update to guidance issued by EPA in 1997. EPA intends to publish this guidance as an appendix to the forthcoming Nonpoint Source Program and Grants Guidelines for States and Territories in early 2013. EPA has released this guidance in November 2012 to assist states and territories in their efforts to update their programs as expeditiously as possible. This guidance is a companion to, but distinct from, the forthcoming 319 grant guidelines. The state’s written NPS management program is the roadmap for all state NPS program activities, including activities supported by resources and programs other than CWA Section 319 funds. Updates to these state nonpoint source programs are vital for EPA and the states to ensure that section 319 funding, technical support and other resources are directed in an effective and efficient manner to support state efforts to address water quality issues.
