SUPPLEMENTARY INFORMATION: 

### .A. Background

Part B of Title III of the Energy Policy and Conservation Act (EPCA) (Pub. L 94-163), as amended by the National Energy Conservation Policy Act (NECPA) (Pub. L 95- 619), and as amended by the National Appliance Energy Conservation Act (NAECA) (Pub. L 100-12) 1 created the Energy Conservation Program for Consumer Products Other Than Automobiles. Among other program elements

, section 323 of the Act requires that standard methods of testing be'prescribed for covered products, including - dishwashers

. Test procedures appear at 10 CFR Part 430

, Subpart B. Test procedures for dishwashers were prescribed on August 3, 1977. 42 FR 39964

, August 6. 1977

. DOE amended the energy conservation program for consumer products by notice Issued September 18, 1980, so that the Assistant Secretary for Conservation and Solar Energy (now called Conservation and Renewable Energy) can temporarily waive test procedure requirements for a particular product

. 45 FR 64108, September 26

, 1980

. Waivers can be granted

. when design characteristics for the particular product either prevent testing of the product according to prescribed test procedures

, or lead to results so unrepresentative of the product's true energy consumption characteristics as to provide materially inaccurate comparative data to

consumers

. On November 14, M6, DOE issued a rule amending the test procedure waiver process to allow the Assistant Secretary for Conservation and Renewable Energy to grant an interim waiver to manufacturers. In addition, the rule made minor revisions to the petition for waiver procedures. 51 FR 42823, November 26, 1986. 10 CFR 430.27(m) states: Within one year of the granting of any waiver

. the Department of Energy will publish in the Federal Register a notice of proposed rulemaking to amend its regulations so as to eliminate any need for the continuation of such waiver

. As soon thereafter as practicable, the Department of Energy will publish in the Federal Register a final rule. Such waiver will terminate on the effective date of such final rule. The dishwasher text procedures prescribed in 1977 were based on dishwashers using 140 'F inlet water and operating with an electrical supply voltage of 115 volts

. DOE amended the test procedures on February 23, 1983, in order to accurately determine the estimated annual operating cost and energy factor for dishwashers that operate with 120 'F inlet water. 48 FR 9202, March 3, 1983 . (Hereafter referred to as the 1983 rulemaking .) DOE further amended the test procedures on November 27,1984

, in order to redefine a water heating dishwasher by deleting the requirement for internal water heating in the rinse phase of a normal cycle

. 49 FR 46533

, November 27, dishwashers

. These dishwashers, in the normal mode

, use cold inlet water (50 'Fonly, heat it to a designated programselected temperature and use an electrical supply voltage of 240 volts, ANDI-CO requested DOE to exclude these dishwashers from the prescribed test procedures

. On August 12, 1984, ANDI-CO filed a Petition for Waiver of DOE's dishwasher test procedures for two models

, Favorite Models 263 and 265. ANDI-CO claimed that these dishwashers incorporate features which are not addressed in the existing test procedures and, consequently

, cannot be tested under the existing DOE test procedures for dishwashers. DOE granted a waiver and established an alternate test procedure for these models on May 8

, 1985

. 50 FR 21488, May 24, 1985. .On April is

, 1987
, DOE published proposed rules to amend the dishwasher test procedure published to accurately determine the estimated annual operating cost and energy factor for dishwashers that operate with 50 'F inlet water and utilize an electrical supply voltage of 240 volts. 52 FR 12342. A public hearing was held on May 28, 1987.

B. Discussion of Comments In response to the proposed amendments
, DOE received comments only from the Whirlpool Corporation. 1. Minimum Temperature of Heated iNater Whirlpool commented that the rule, as proposed
, did not require that water be heated to above 120 'F, while the discussion section stated this was being proposed. Whirlpool implied that without this requirement a manufacturer of this type of dishwasher could avoid heating the water and that "artifically low energy costs would result because the amendment does not require water to be heated above even 50 'F. Thus, manufacturers who are concerned with good washing performance and who ensure temperatures of 120 'F and above will be penalized." DOE acknowledges that the proposed rule did not require that water be heated above 120 'F for any portion of the washing or drying cycle. Previously, for dishwashers using 120 'F supply water, there was no requirement that water be heated to a specified minimum temperature. The only requirement that

was-included in Clre definitiono a water heating dishwasher was the provision that "thermostatically controlled internal water heating [be] in at least one wash phase of the normal cycle." ' Part B of Title III of SPCA

B. Discussion ofComments



### Inresponse 

### to the proposed amendments, DOE received comments only from the Whirlpool Corporation.


### 1. Minimum Temperature af Heated 11'ater

Whirlpool commented that the rule, 8S proposed. did not require that water be heated to above 120 OF, while the discussion section stated this v.;as being proposed.

Whirlpool implied that without this requirement a manufacturer of this type 

### ofdishwasher could avoid heating the water and that "artificallylow energy costs would result because the amendment does not require water to be heated above even 50 

### OF. Thus. manufacturers who are concerned with good washing performance and who

ensure temperatures of 120 

### OF and above will be penalized."

DOE aclmowledges that the proposed rule did not require that water be heated above 120 

### OF for any portion ofthe washing or drying cycle. Previously, for dishwashers using 120 

### OF supply water. there was no requirement that water be heated to a specified minimum temperature. The only requirement that .was-includedinilie-dii"finitloi:iof1fwatet. heating dishwasher was the provision that "thermostatically controlled internal water heating [be] in at least

one wash phase ofthe normal Cyc1fl."

### 47550 Federal Register / Vol. 52, No. 240 / Tuesday, December 15, 1987 / Rules and Regulations

DOE now is revising the definition of a "water heating dishwasher " specifically to include the requirement of "providing internal water heating to above 120 'Fin at least one wash phase of the normal cycle." (Emphasis added.) DOE continues to believe that no specified minimum temperature above 120'F is needed for the reasons discussed below.


### 2. Dishwasher Performance Whirlpool commented extensively on its laboratory findings of the need to provide 140 'F for effective removal of food fats from dishes. Whirlpool cited test results in its laboratory showing 145 'F to be the first temperature to effectively remove these fats, i.e., shortening

, peanut butter and cream cheese, from dishes. .. In addition, Whirlpool cited its test results showing that 140 'F for the final rinse cycle was needed in order to achieve 100 percent drying. Whirlpool raised the issue of performance in the 1983 and 1984 rulemakings. 48 FR 9202, March 3, 1983, and 49 FR 46533, Nov. 27,1984. DOE believes the issue of dishwasher performance raised in the 1983 and 1984 rulemakings for water heating dishwashers designed to heat inlet water of 120 'F is the same issue being addressed today for water heaters designed to heat inlet water of 50 'F to above 120 'F. Arguments addressed and resolved in 1983 and 1984 apply to either of these types of "water heating dishwashers. " 

### DOE's response to the comments received in these earlier rulemakings concerning performance testing for dishwashers remains unchanged. In the 1983 rulemaking, DOE stated: DOE believes that it would be extremely difficult to quantify these subjective factors into one test that is easily repeatable (testing in one laboratory) and reproducible (testing among laboratories) ' * '. Manufacturers have generally commented that dishwashing performance should be excluded from the dishwasher test procedure. DOE believes in allowing manufacturers to determine for themselves whether the dishwashing performance for water heating dishwashers is acceptable

. See 49 FR 9202, 9204. While in the 1984 rulemaking. DOE stated: With respect to the need for 140 'F water: "DOE continues

- to believe

, as in the March 1983 final rule
, that a requirement to heat water to a specified minimum temperature 1140'F) is unnecessarily restrictive in the test procedure and could exclude steam dishwashers from the water heating dishwashers category

. See FR 4M33

. 46534. Today's final rule for water heating dishwashers is believed to be sufficient with the inclusion of the following language in the definition: "providing internal water heating to above 120 'F in at least one wash phase of the normal cycle."

C. Environmental

, Regulatory Impact, and Small Entity Impact Reviews


### 1. Environmental Review Since today's final rule will be used only to standardize the measurement of energy usage, and will not affect the quality of distribution of energy usage, prescribing test procedures will not result in any environmental impacts. DOE, therefore, has determined that prescribing test procedures under the energy conservation program for consumer products clearly is not a major Federal action significantly affecting the quality of the human environment within the meaning of the National Environment Policy Act of 1969. Consequently, neither an Environmental Impact Statement nor an Environmental Assessment is required for today's final rule. 2. Regulatory Impact Review
The final rule has been reviewed in accordance with Executive Order 12291 which directs that all regulations achieve their intended goals without imposing unnecessary burdens on the economy, on individuals, on public or private organizations, or on State and local governments . The Executive Order also requires that regulatory impact analyses be prepared for "major rules." The Executive Order defines "major rule" as any regulation that is likely to result in: (1) An annual effect on the economy of $100 million or more; (2) a major increase in costs or prices for consumers, individual industries, Federal, State, or local government agencies

, or geographic regions; or (3) significant adverse effects on competition, employment, investment, productivity, innovation
, or on the ability of the United States-basedenterprises to compete with foreignbased enterprises in domestic or export markets. 

### This final rule makes only minor changes in the test procedures for dishwashers to allow for more accurate determinations of estimated annual operating cost and energy factor. Therefore, DOE has determined that this final rule does not come within the definition of "major rule."
3. Small Entity Review The Regulatory Flexibility Act, Pub. L. 96-345 (5 U.S.C. 601-612), requires that an agency prepare an initial regulatory flexibility analysis to be published. This requirement (which appears in section 603) does not apply if the agency "certifies that the rule will not, if promulgated, have a significant economic impact on a substantial number of small entities ." The rule affects manufacturers of dishwashers. As previously discussed, the changes will not have significant economic impacts, but rather will simply improve the test procedures. Furthermore, DOE is not aware of any dishwasher manufacturers that would be considered small entities under the Act. Therefore, DOE certifies that this final rule will not have a " significant economic impact on a substantial number of small entities." In consideration of the foregoing, Part 430 of Chapter II of Title 10, Code of Federal Regulations is amended, as set forth below.
