Methods Development & Approval Process
You will need Adobe Reader to view some of the files on this page. See EPA's PDF page to learn more.
Office of Solid Waste's (OSW) manual of EPA-approved analytical methods, Test Methods for Evaluating Solid Waste, Physical/Chemical Methods (SW-846), ensures the availability of established, validated methods for the measurements and monitoring needed for the RCRA program. All of the methods published in SW-846 have been approved by EPA. While EPA cannot evaluate every applicable method, the Agency does conduct scientific evaluations of new methods that:
- offer cost-effective alternatives or significant improvements in data quality, and
- are expected to find broad application in environmental monitoring. These methods are then published in SW-846.
- Part One explains how to obtain assistance from the Methods Team during the method development and evaluation process, and
- Part Two explains the actual process of applying for inclusion of a new measurement or monitoring method in SW-846.
Part One: Technical Assistance

The Methods Team supports the development of new measurement technologies by:
- Assisting developers in designing proof of concept studies.
- Hosting forums to facilitate the interchange of ideas between the user and developer communities to stimulate development of new techniques.
- Assisting developers in designing evaluation studies prior to submitting an application for new method approval.
Part Two: The Application Process
To have a method published in SW-846, applicants must follow certain
procedures established by the Methods Team. Adherence to these requirements
can help speed the approval process.
When a method project is completed, the developer should assemble a package
of documents describing the project and submit it to the Agency for review
and evaluation. The documentation package should include:
- Hard and electronic copies of the method. See SW-846 4th Edition Method Style Guide - 11/28/05 (PDF) (33 pp, 190K) the supporting document describing the rationale behind the method development effort and how the key elements described in the document were addressed.
- A data package containing both the raw and summarized single-laboratory and multilaboratory data.
- Any diagrams of specific equipment and instrument results (e.g., chromatogram or spectra) pertinent to the demonstration of appropriate performance for the intended application method.
- Copies of any references listed in the method.
- Any method-specific quality control criteria.
The above material should be submitted in hard copy and on disk (preferably
in WordPerfect 9 or MS Word 2002) to the following address:
U.S. Environmental Protection Agency
Office of Solid Waste
1200 Pennsylvania Ave. NW (5307P)
Washington, DC 20460
Method Evaluation Criteria
EPA uses the following criteria when evaluating a new method:
- Is there a need for the intended scope and application of the method?
- Will the submitted method generate data consistent with the intended
scope and application of the method?
- Have appropriate quality control procedures been developed for this procedure?
