Expedited Method Approval Process

EPA can use an expedited process to announce the approval of new drinking water analytical methods in the Federal Register. The process provides laboratories and water systems more timely access to new alternative testing methods than the traditional rulemaking process.

Expedited Method Approval Requirements

There are several requirements that must be met before a new method can be approved using the expedited process.

New methods may be submitted for evaluation under the Alternate Test Procedure (ATP) program. A new method can be considered for approval using the expedited process, if it has performance characteristics that fall within the range of performance characteristics obtained by the methods listed in regulation for the same contaminant.
