SUPPLEMENTARY INFORMATION :

A. Bccnc,nouoo Development of test procedures is one discrete part of the energy eorlservationprogram for appliances. Even when preomulgateci, final test procedures will notof themselves require L--sting to be conducted. They will merely establish standLrd methods for testing when testing vs otherwise required by the Act itself or by regulations implementing other harts of the program. For example, the Federal "Prude Comnnission h -j. exercising its appliance energy efficiency labelling;c.•utho city regarding a par; titular appliance type, may well require the application of substemetially less tiwm.n all of the

A. further proposal of Subpart C will be necessary in order to meet the requirements of section 325 (a ) (1) of the Act as amended by section 161 of the Energy Conservation and Production Act (Pub. L.94-385) Subpo.vt A, r. previously proposed 19;.77, - 1 4, 1976; 42 FR 15 33, March 22, lu'77), contained definitions in proposed section 430.2, some of which are applicable to the test procedures for 9 it heaters, in addition, PEA is today .>rcl'uoming to further amend proposed 4130.2 icy adding to the definition of"Basic model" 2 subparagraph (5) applyirlg speci_rcally to water heaters, by r"propc _rig the definition of "electric water heater," and by adding definitions of "water heater," "gas water heater," and "oil .v.iter heater," By notice issued July 22, 1973 (:4 31237, July 27, 1076), FEA proposed ^an amendment to proposed Part 430 to adda Subpart B which would contain the appliance test procedures-required to be prescribed by section 323 of the Act. The notice issued July 22 described the requirements of section 323 and set forth proposed test procedures for room air conditioners. A further notice issued March 21, 1977 (42 FR 16311, March 30, "+_977) solicited comments with respect toa clarification of the provision concerning the number of units to be tested. By notice issued March 17, 1977 (42 F.R 15423, March 22, 1977) FEA proposed an amendment setting forth proposed testprocedures for dishwashers. Test procedures for several other products are in the process of being proposed at this time. Section 323(a) (2) of the Act requires FEA to direct the National Bureau of Standards Act (NBS) to develop for 13 types of covered products test procedures for the determination of the estimated annual operating costs and at least oneother useful measure of energy consumption which FEA determines is likely to assist consumers in making purchasingdecisions. Pursuant to the Act, ERA directed NBS to develop test proceduresfor FEA's use in prescribing test procedures under the Act. As part of thisundertaking, IBS was required to evaluate existing test procedures for measuring energy consumption of water heaters.
NBS has transmitted ta FEA a testprocedures review document which reviewed existing test procedures for measuring energy consuunption for waterheaters and recomrmencled test procedures. Copies of this review document will be made available for inspection by Interested persons as provided for later in this notice. 

### Under the Department of Commerce Voluntary Labelling Prog- a r1, proposed test procedures and labeling proceduresfor water heaters were published as Voluntary Specification No. 5-75 on August 14, 1975. A final specification was prepared In December 1975. Final publication of these voluntary proced was withheld upon enactment (- A k These test methods were ueveiuf..d at S with cooperation from ti , Gas Appliance Manufacturers Association. These tests are based on the American NL-J'Pior,<,.l Standards (ANSI) Z21.10.1 a Water Heaters and C72.1 Electric Water m i",c The test procedure proposed today ljij'er p rom the Voluntary Labelling or_ i^st. procedures in that all tests 'vely without the tank is daily water usage is dirierent, €^ ^d oil-there=d water heaters h,ive been included. These changes are c._pected generally to reduce the testing burde , me nmarnufcctu e_'s.

B. !fE,%WRT_S OF ENER GY CONSUMPTION The Act requires F'EA to prescribe test »rocedures for the deterrnination of estimated annual operating costs and at least one other useful measure of energy oonsiunption which the administrator determines is likely to a ssist consumers in conking purchasing decisions

. The estim ated annual operating cost
, proposed for both electric water heaters and gas or 

### oil water heaters in s 430.22(e) (1), is based upon daily energy consumption, a 

### representative average use cycle of 365 days (representing the total number of, Jays in a year) and repr esentative aver age unit energy costs. Also proposed (§ 430.22(c' (2) ) as test procedures for the determination of 

### other measures of energy consumption which are likely to assist consumers in, making purchasing decisions are test procedures regarding the energy factor for water heaters. The energy factor is defined as the daily water heating energy to the daily energy consumption. The daily seater heating energy represent, the heat content of the average amount of water provided by the water heaterper day. Among other possible applications, the energy factor may be used by FEA to determine the efficiency of hot water heaters for the purposes of theefficiency improvement program described by section 325 of the Act. An additional proposed ineasus'e (§ 430.22(e) (3)) that is likely to assistconsumers in making purchasing decisions is the hot water supply rating which is a measure of the amount of water that can be supplied by the water heater in a given period of time.

### FEA recognizes that there may be additional useful measures of energy corisurnption for water heaters other than the measures described above. Accordingly, today ' s proposal
, in proposed§ 430.22(e) (4), provides for other useful measures which the Administrator 

### determines, are likely to assist consumers i?1 making purchasing decisions. These measures, however, must be derived from the application of the uniform test method proposed today as Appendix E to Subpart B. Water heater manufacturers would, if required

, only have to perform various computations while still applying only the same test method c ontained In Appendix: B. For example

These numbers are used as the reference. "typical" water heater without heat traps installed In the piping system. Piping losses are included In the calculated energy and are accounted for inthe coeifcfents used (i.e., the 61.3 gadIons per day and 90° F rise).

D. REPRESENTATIVE Av.:ACL-USE CYCLE

Section 323 ( b) (2) (42 U.S.C. 6293(b)

## (2)) of the Act provides that test procedures for determining estimated annual operating costs of any covered product shall be 'calculated from iiic rrurements Cl e _ergy is is C,. lel}rcscncatiie av r age-use cycle as determined by the Adnir t.•ator ) and from representative average unit costs (as provided by the Administrator ) needed to operate such product during such c cic. lEA has de= termined that the representative aver

### e-use cycle for water heaters is 365 days per year, sinc e water heaters typically are used every day of the year. Typical, or standard

, values for the representative average volume of hot n'ater usage and temperature rise occurring in producing hot water also arenecessary elements in the estimated annual operating cost and the energy factor of ter heaters

. FEA is using 64.3 gallons per day and 90 F temperature rise for these two values, respectively, in the test procedures proposed today. The 90° P temperature rise representsthe national average inlet water temperature: for the U.S. of 55° F and the usual factory thermostate setting of 145° F. Normally, at the factory, gas and oil water heater thermostats are set at 140° F and electric water heater thermostats are set at 150° F. The 64.3 gallons per day of hot water was derived from information obtained from a, survey conducted by NBS, of a number of gas and electric utility
companies regarding hot water energy usage data. Data supporting these usage conditions are available in the NBS test procedure review document as provided for later in this notice. 

### FDA. in ends to develop representative average unit costs of energy needed to, calculate the annual operating cost for the representative average use cycle andto provide this, information to manulecturers and the FCC on or before- the effective date of test procedures for water heaters.

H. ENVIRONMENTAL AND INFLATIONARY RsvIEw As required by section 7(c) (2) of the Federal Energy Administration Act of 1(;74 (Pub. L. 93-275 ), a copy of this notice has been submitted to the Administrator of the Environmental Protection Agency for his comment s concerning the impact of this proposal on the quality of the environment. The Administrator has no comments. The National Environmental Policy Act of 1969 requires FEA to assess the environmental impacts of any proposal by the Agency for "mtlajor Federal actions significantly affecting the quality of thehuman environment." Since test procedures tinder the conservation programfor appliances will be used only to stanclardize the measurement of energy usage and will not ifert the qufiitity or distribution of energy usage, FEA has determined that the action of prescribing test procedures
, by itself
, will not result in any environmental impacts . On this 

### basis

, PEA has determined that, with respect to prescribing test proceduresunder the conservation program for appliances

, no environmental impact statement is required.The proposal has been reviewed in accordance with Executive Order 11821 as amended by Executive Order 11949, and O Circular No. A-107 and has been determined not to be a major proposalrequiring evaluation of its economic impact as provided for therein
