Fact Sheet
      Streamlining EPA's  Test Methods  Approval

      Program

      Summary
      EPA is proposing a regulation to streamline EPA's program for approving laboratory test procedures
      and quality control measures that are used to gather data and monitor compliance under the Clean
      Water Act (CWA) and the Safe Drinking Water Act (SDWA). It demonstrates EPA's commitment to
      reducing the regulatory burden imposed on industries and municipalities, the technology development
      community, and the laboratory services community. It also demonstrates EPA's commitment to
      lowering the barriers to innovative technology.

      The proposed regulation will make it easier for the affected communities to modify an approved
      reference method by streamlining the regulatory requirements and it will provide an opportunity for non-
      EPA organizations to develop and gain approval of entirely new methods.  The objective of the
      proposal is to encourage early introduction and use of innovative technologies that reduce costs,
      overcome analytical difficulties, and  enhance data quality.  The proposal provides  safeguards to ensure
      that method modifications produce data of equivalent or superior quality to the data produced by
      approved methods.
      Background
      The U.S. Environmental Protection Agency
      (EPA) publishes laboratory analytical methods
      that are used by industrial and municipal
      facilities in analyzing the chemical and
      biological compo- nents of wastewater, drinking
      water, sediment, and other environmental
      samples that are required by EPA regulations
      under the authority of the Clean Water Act and
      the Safe Drinking Water Act.

      Almost all of these methods are published by
      EPA as regulations at Title 40 of the Code of
      Federal Regulations (CFR).  As regulations,
      however, they have been considered
      prescriptive and, as a result, have limited the
      ability of facilities to incorporate procedures that
      would account for unique situations. They also
      have not allowed for the incorporation of recent
      advances in measurement technology.

      Reducing the Burden
      Recently there has been a growing awareness
      within both EPA and the analytical community
      that compliance with the Agency's regulations
      imposes an unintended regulatory burden on
      the regulated community and that this
      potentially creates a barrier to innovation in
      environmental monitoring. This proposed
                                 regulation is intended to change this situation.

                                 The Proposed Regulation
                                 The proposed streamlining rule (1) increases
                                 the flexibility of affected parties to modify
                                 existing test procedures without regulatory
                                 action, (2) expedites approval of new and
                                 modified test procedures,  (3) establishes and
                                 requires the use of standardized Quality Control
                                 (QC) and QC acceptance criteria,  and (4)
                                 recommends use of standard data elements for
                                 reporting test results. This proposal sets the
                                 stage for  harmonization of wastewater and
                                 drinking water test procedures.

-------
   BENEFITS OF THE PROPOSED RULE

 > New incentives for developing new analytical
    techniques

 > Improved performance in specific wastewater
    discharge or drinking water situations

 > Lower costs of environmental measurements
    and improved laboratory productivity

 > Increased consistency among analytical
    methods, appropriate validation testing levels
    and timely approval of methods
Public Participation
EPA is developing this proposed regulation with
the help of representatives from municipal
water and wastewater treatment utilities,
industries, laboratories, instrument vendors,
equipment manufacturers, consensus standards
organizations, educational institutions, other
Federal agencies, and other interested parties.
EPA held four public meetings on the
streamlining  proposal between September 1995
and July 1996.

Additional Information and Copies
EPA developed three supporting documents to
help the regulated community implement this
regulation: Guide to Method Flexibility and
Approval of EPA Water Methods (EPA-821-D-
96-004), Guidelines  and Format for Methods to
Be Proposed at 40 CFR Part 136 or Part 141
(EPA-821-B-96-003), and Methods for Organic
Chemical Analysis of Municipal and Industrial
Wastewater (EPA-821-B-96-005). These
documents provide a detailed description  of the
streamlining  proposal and provide
implementation guidance.

action, you may contact Marion Thompson at

information and how to  review the public record
for this rulemaking.
