  • National Management Measures to Control Nonpoint Source Pollution from Agriculture, July 2003
    Technical guidance and reference document for use by State, local, and tribal managers in the implementation of nonpoint source pollution management programs. It contains information on the best available, economically achievable means of reducing pollution of surface and ground water from agriculture.
  • Chesapeake Bay Federal Land Management Guidance , May 2010
    Chapter 2 of this guidance presents the implementation measures component of Nutrient Management Plans that would maximize nutrient reductions by agriculture. Three types of practices are necessary in agricultural production to control nutrients and sediments. These three types avoid, control, and trap pollutants (ACT), and practices that suit each should be implemented in agricultural production.
