Flexible Approaches to Environmental Measurement

In 1997, EPA adopted the Performance Based Measurement System (PBMS) (i.e., Federal Register Notice of Intent) to:

  • Reduce the cost of monitoring;
  • Stimulate the development and use of innovative technologies;
  • Speed up the introduction of new methods; and
  • Improve the quality of science in the monitoring community.

Unfortunately, the "one size fits all" approach did not work for the diversely different programs and authority within each EPA office. The guidance document Flexible Approaches to Environmental Measurement, created in 2008, shifted the focus from the performance approach to a more flexible one. Documentation on EPA's commitment to this flexible approach is below, in addition to a presentation on the specific steps being taken within each media program.
