. The Department will consider all views and statements submitted by July 14, 1995, in formulating a Notice of Proposed Rulemaking regarding faucets , showerheads, water closets , and urinals.



### II. WELCOMING REMARKS AND INTRODUCTIONS

III. DISCUSSION OF THE FOLLOWING AGENDA ITEMS: All covered products that use energy are subject to the requirements in the Code of Federal Regulations, 10 Part 430 (for example., certification and enforcement). Section 430.60, "Purpose and Scope," states,"The regulations in the subpart set forth the procedures to be followed for certification and enforcement testing to determine whether a basic model of a covered product complies with the applicable energy conservation standard set forth in subpart C



### 1of this part." The Department believes that the same requirements should also apply to plumbing

products .

A. Certification Requirements
1) Submission of data requirements for appliances using energy are stated in section 430.62. The Department requires that each manufacturer or private labeler before distributing in commerce any basic model of a covered product subject to the applicable energy conservation standard to certify by means of a statement of compliance and certification report, that each model meets the requirements of that standard. For example, the Department currently requires water heater manufacturers to submit certain information for each basic model in its certification report to DOE: energy factor, rated storage volume, product type and class, manufacturer's name, and manufacturer's basic model number. The Department believes that comparable requirements should be established for plumbing products.

The Department requests information as to what type of data manufacturers should submit to certify that their products meet the applicable water use standards.
2) Statistical sampling plans that provide the basis of a manufacturer ' s claim in their certification report to the Department that their products meet the applicable energy efficiency standards , are stated in section 430.63. Section 430

.63, "Sampling," states , " For purposes of a certification of compliance , the determination that a basic model complies with the applicable energy performance standard shall be based on the sampling procedures set forth in section 430.23 of this part." The sampling procedures used in the energy conservation program to provide manufacturers ' certification require the testing of a minimum of two units of a basic model at confidence levels that range from 90 to 971/z%. A one time submission regarding the basic model is all that is needed if no change occurs to the basic model that would affect energy consumption

. The Department believes that comparable requirements should be established for plumbing products. • The statistical sampling plans provide the basis of a manufacturer's claim in its certification report to the Department that its covered products meet the applicable water use standards. The Department requests information as to what type of statistical sampling plan should be utilized in certifying faucets, showerheads, water closets, and urinals.
3) The Code of Federal Regulations , in 10 CFR Part 430, section 430.2, provides a definition for the term " basic model " in regard to the appliance program : " Basic model means all units of a

-2-given type of covered product (or class thereof) manufactured and -with respect to * * * which

have electrical characteristics that are essentially identical, and which do not have any differing physical or functional characteristics that affect energy consumption." Basic model is a term used to describe,a product or item of equipment whose performance, design, mechanical, and functional characteristics are essentially the same. Components of similar design may be substituted in a basic model without requiring additional testing if the represented measures of energy consumption continue to satisfy applicable provisions for sampling and testing. The Department believes that comparable requirements should be established for plumbing products .

The Department requests information and advice in defining the term "basic model" so that all units of a given type of the covered product with essentially the same water use (hydraulic) characteristics will be covered by the same certification report. 

### B. Testing Requirements for Multi-User Fittings
Multi-user fitting (faucets) are generally installed on lavatories, and have multiple outlets/nozzles which can be used simultaneously by multiple users to provide individualized or collective flows.

The Department requests information on how to treat faucets that can be used simultaneously by multiple users, and that are generally installed in lavatories, i.e., are these covered products and why ? If not, and why? If these are considered covered products, how should the standards be applied?



### C. Other Issues (If Time Permits)

IV. SUBMISSION OF DATA All information gathered from today's workshop, and all written statements submitted by July 14, 1995, will be available for public inspection from 9:00 A.M. - 4:00 P.M in the Department of Energy Freedom of Information Reading Room (Room No: 1E-190), telephone number (202) 586-6020. Written statements (10 copies) must be submitted by Friday, July 1.4, 1995. In addition, the Department will appreciate an electronic copy of each statement submitted. The Department is currently using WordPerfect 5.1. Comments submitted by telefax will not be accepted. Statements should be labeled "Test Procedures and Certification Requirements for


### -3Plumbing Products," and submitted to Ms. Sandy Cooper, Office of Energy Efficiency and

Renewable Energy, Mail Station EE-43, U.S. Department of Energy, 1000, Independence Avenue, SW, Washington, DC 20585. Telephone: (202) 586-7574. Any person submitting information that he or she believes to be confidential and exempt by law from public disclosure should submit one complete copy and eight copies from which information claimed to be confidential has been deleted. In accordance with the procedures established at 10 CFR 1004.11, the Department of Energy shall make its own determination as to whether the information shall be exempt from public disclosure.
