EPA's Mission:

Protect human health and safeguard the natural environment — air, water, land — upon which life depends.

slide3

EPA Organization and Goals

EPA's 10 Strategic Goals:

  • Clean Air
  • Clean and Safe Water
  • Safe Food
  • Preventing Pollution and Reducing Risk in Communities, homes, Workplaces and Ecosystems
  • Better Waste Management and Restoration of Contaminated Waste Sites
  • Reduction of Global and Cross Border Environmental Risks
  • Expansion of Americans’ Right-to-Know
  • Sound Science, Improved Understanding of Environmental Risk and Innovation to Address Environmental Problems
  • A Credible Deterrent to Pollution and Greater Compliance with the Law
  • Effective Management
slide4

The National Center for Environmental Research

(NCER)

  • ORD provides the leadership in science and conducts most of EPA’s research and development
  • NCER is one of two Centers that, together with three National Laboratories, comprise the Office of Research and Development
  • NCER is ORD’s extramural research arm
  • ORD’s research budget is approx. $550 million, with $100 million for competitive extramural grants and fellowships (STAR)
  • ORD in cooperation with other EPA offices selects topics for research in the STAR program
slide5

STAR Program

  • Established in 1995 as part of the overall reorganization of ORD
  • Mission: include this country’s universities and non-profit centers in EPA’s research program and to ensure the best possible quality of science in areas of highest risk and greatest importance to the Agency
  • Award about $100 million annually
  • Manage about 1000 active research grants and fellowships
  • Each year: receive 3000-3500 grant applications; make about 300 new STAR awards
slide6

NCER’s Extramural Programs

Science To Achieve Results (STAR)

Targeted Research Grants through Requests for ApplicationsRFAs-Directed specifically towards national environmental science needs as related to the mission of EPA: Topics selected to complement in-house research program
