ABSTRACT

Anyone can request that EPA approve a new method or modification of a method already approved by EPA, by submitting EPA-specified data and other information to the Director, Analytical Methods Staff, Office of Science and Technology (MS4303), Office of Water, USEPA, 401M Street, SW, Washington, DC 20460. EPA will evaluate the material to determine whether the method meets EPA criteria. If a method meets the specified criteria, it will be approved. This involves a formal proposal in the Federal Register, public comment, and finally (unless otherwise indicated by the public comments or other new information), promulgation in the Federal Register. Once approved (i.e. promulgated), any laboratory may use the method.
