The purpose of this letter is to inform you of the convening of a public workshop on June 15, 1995, to discuss issues and exchange information regarding water use standards, testing for water use, and compliance certification requirements for plumbing products covered under the Energy Policy Act of 1992, Public Law 102-486. In order to get the maximum public input for the Department's rulemaking for plumbing products, the Department seeks discussion on the following issues: • A definition of "basic model" for plumbing products so that different products with essentially the same water use characteristics will be covered by the same test and certification. • Sampling plans to ensure that results from testing a few fittings (i.e., faucets and showerheads) and a few fixtures (i.e., water closets and urinals) will establish the water use of a larger population of the same fittings and fixtures. • Data to be submitted to the Department by manufacturers certifying their products meet water use standards. • How to treat faucets that can be used simultaneously by multiple users, and that are generally installed in lavatories. The Department invites you to participate in the June 15, 1995, public workshop. The Department believes that the workshop will enable the Department to obtain information which will facilitate the preparation of the Notice of Proposed Rulemaking. Enclosed is a list of organizations to whom this letter was sent. Participants in the public workshop should inform Mr. William W. Hui of my staff (202/586-9145) of their attendance by June 12, 1995.
