    Energy.
    
    ACTION: Notice of proposed rule and public hearing.
    
    -----------------------------------------------------------------------
    
    SUMMARY: The Energy Policy and Conservation Act, as amended (EPCA), 
    requires the Department of Energy (DOE or the Department) to administer 
    an energy and water conservation program for certain major household 
    appliances and commercial equipment, including certain plumbing 
    products. This proposed rule would codify water conservation standards 
    and test procedures established in EPCA for plumbing products, 
    incorporate by reference water conservation standard and test 
    procedures for faucets and test procedures for showerheads revised by 
    the American Society of Mechanical Engineers/American National 
    Standards Institute (ASME/ANSI), and provide for certification of 
    compliance with plumbing product standards. This proposed rule would 
    also clarify the certification requirements applicable to all 
    residential appliances.
    
    DATES: The Department will accept comments, data, and information 
    regarding the proposed issues of this notice no later than May 6, 1997.
        The public hearing will be held on March 31, 1997 in Washington, 
    DC. Requests to speak at the hearing must be received by the Department 
    no later than 4:00 p.m., March 21, 1997. Ten (10) copies of statements 
    to be given at the public hearing must be received by the Department no 
    later than 4:00 p.m., March 21, 1997.
    
    ADDRESSES: Written comments and requests to speak at the public hearing 
    should be labeled ``Test Procedures and Requirements for Plumbing

    I. Introduction
    
    A. Authority
    
        Part B of Title III of the Energy Policy and Conservation Act of 
    1975, Pub. L. 94-163, as amended, (EPCA), by the National Energy 
    Conservation Policy Act of 1978 (NECPA), Pub. L. 95-619, the National 
    Appliance Energy Conservation Act (NAECA) of 1987, Pub. L. 100-12, the 
    National Appliance Energy Conservation Amendments of 1988 (NAECA 1988), 
    Pub. L. 100-357, and the Energy Policy Act of 1992 (EPAct), Pub. L. 
    102-486, created the Energy Conservation Program for Consumer Products 
    other than Automobiles (Program). The products covered under this 
    program include faucets, showerheads, water closets, and urinals--the 
    subjects of today's notice of proposed rulemaking.
        This Program consists essentially of three parts: testing, 
    labeling, and energy and water conservation standards. In the case of 
    faucets, showerheads, water closets, and urinals, the test procedures 
    measure water use or estimated annual operating cost of these covered 
    products during a representative average use cycle or period of use, as 
    determined by the Secretary, and shall not be unduly burdensome to 
    conduct. EPCA, Sec. 323(b)(3), 42 U.S.C. Sec. 6293(b)(3).
        Effective 180 days after a test procedure applicable to a covered 
    product is prescribed or established, no manufacturer may make a 
    representation with respect to water usage of such products unless such 
    products have been tested in accordance with such test procedures and 
    such representation fairly discloses the results of such testing. EPCA, 
    Sec. 323(c)(2), 42 U.S.C. Sec. 6293(c)(2). However, the 180-day period 
    may be extended for an additional 180 days if the Secretary determines 
    that this requirement would impose an undue burden. EPCA, 
    Sec. 323(c)(3), 42 U.S.C. Sec. 6293(c)(3).
        EPCA states that the procedures for testing and measuring the water 
    use of faucets and showerheads, and water closets and urinals shall be 
    ASME/ANSI Standards A112.18.1M-1989, and A112.19.6-1990, respectively, 
    but that if ASME/ANSI revises these requirements, the Secretary shall 
    adopt such revisions if they conform to the basic statutory 
    requirements for test procedures. EPCA, Sec. 323(b)(7) and 323(b)(8), 
    42 U.S.C. Sec. 6293(b)(7) and Sec. 6293(b)(8).
        EPCA prescribes water conservation standards for faucets, 
    showerheads, water closets and urinals. It further provides that if the 
    requirements of ASME/ANSI Standard A112.18.1M-1989 or ASME Standard 
    A112.19.6-1990 are amended to improve the efficiency of water use, the 
    Secretary shall publish a final rule establishing an amended uniform 
    national standard unless the Secretary determines that adoption of such 
    a standard at the level specified is not (i) technologically feasible 
    and economically justified, (ii) consistent with the maintenance of 
    public health and safety; or (iii) consistent with the purposes of this 
    Act. EPCA, Sec. 325(j) and 325(k), 42 U.S.C. Sec. 6295(j) and 
    Sec. 6295(k).
    
    B. Background
    
        EPCA requires that DOE amend the plumbing products test procedures 
    and standards established by statute to conform with revisions to 
    standards by ASME/ANSI if certain requirements are met. The applicable 
    faucet standard and the test procedures for faucets and showerheads, as 
    prescribed by EPCA, were in ASME/ANSI Standard A112.18.1M-1989. On 
    September 15, 1994, ASME/ANSI Standard A112.18.1M--1994 was issued and 
    DOE initiated a review as required.
        The Department held a public workshop with representatives from the 
    Plumbing Manufacturers Institute (PMI), its manufacturer members, 
    Federal and state agencies, and water conservation organizations in 
    Washington, DC on June 15, 1995. The following issues were discussed: 
    (a) definitions of ``basic model'' for faucets, showerheads, water 
    closets, and urinals; (b) statistical sampling plans for certification 
    testing; (c) certification reporting requirements for plumbing 
    products; and (d) whether multiple-user ``sprayheads'' are considered 
    covered products, and if so, how the faucet standards are to be 
    applied. Subsequently, various attendees at the workshop filed 
    comments. Several comments covered the issue of enforcement which will 
    be addressed in section (II)(B)(8).
        Four letters from the industry (W/C Technology Corporation, July 
    14, 1993; Plumbing Manufacturers Institute, February 7, 1994; and 
    Bradley Corporation, February 9, 1994, and August 12, 1994) concerning 
    issues relating to today's notice (e.g., definition for 
    ``electromechanical hydraulic toilet,'' and multiple-user sprayheads) 
    were submitted to DOE prior to the June 15, 1995, public workshop. The 
    Department will consider these as part of the public comment received.
        The Department held a second public meeting in Washington, DC on 
    February 28, 1996, to further discuss the statistical sampling plans 
    that would be used to certify compliance, and new issues concerning: 
    (a) incorporation of the test procedure requirements for faucets and 
    showerheads, and standard for faucets contained in ASME/ANSI Standard 
    A112.18.1M-1994; (b) an effective date to allow manufacturers to test 
    and make initial compliance certification submissions after such 
    requirements are published in a final rule; and (c) a uniform 
    mathematical rounding method and how it is to be used to convert test 
    data into final results for the purpose of determining compliance. Four 
    comments (Eljer Industries (Eljer), Mr. R. Michael Martin, and two from 
    PMI) were received subsequent to the second public meeting.
    
    II. Discussion
    
    A. Statutory Plumbing Requirements
    
        DOE is proposing to codify into the Code of Federal Regulations 
    statutory requirements with respect to plumbing products--including 
    test procedures, water conservation standards, and definitions. EPCA 
    also requires that if specified ASME or ASME/ANSI standards or test 
    procedures are amended, DOE must amend the regulatory requirements to 
    conform with the revisions if certain requirements are met.
        Comment is invited on those provisions of the proposed water 
    conservation standards and test procedures that differ from the current 
    statutory standards. Comments on standards or test procedures 
    established by statute will not be considered.
    1. Test Procedures
        The Department proposes to add the following descriptors as 
    measures of water usage for faucets, showerheads, water closets, and 
    urinals: maximum permissible water use (in gallons and liters per 
    minute or cycle, and gallons and liters per flush), at 10 CFR sections 
    430.23(s)-430.23(v), respectively. The test procedures for measuring 
    water usage are discussed below.
        (a) Faucets and showerheads. EPCA states that test procedures for 
    showerheads and faucets shall be the test procedures specified in ASME 
    A112.18.1M-1989 for such products but if ANSI revises these 
    requirements, the Secretary shall adopt such revisions if they conform 
    to the basic statutory requirements for test procedures. EPCA, 
    Sec. 323(b)(7), 42 U.S.C. Sec. 6293 (b)(7).
        The test procedure requirements for faucets and showerheads in 
    ASME/ANSI Standard A112.18.1M-1989 were revised and issued as ASME/ANSI 
    Standard A112.18.1M-1994 on September 15, 1994. These revised test 
    procedures appear to be reasonably designed to produce test results 
    which
    
    [[Page 7836]]
    
    measure water use or estimated annual operating cost of a covered 
    product during a representative average use cycle and appear not to be 
    unduly burdensome to conduct. See EPCA, Sec. 323(b)(3), 42 U.S.C. 
    Sec. 6293(b)(3). Therefore, the Department proposes to incorporate by 
    reference, section 6.5, ``Flow Capacity Test in ASME/ANSI Standard 
    A112.18.1M-1994, for testing faucets and showerheads at Appendix S of 
    Title 10 CFR Part 430, Subpart B.
        (b) Water closets and urinals. EPCA states that the test procedures 
    for water closets and urinals shall be the test procedures specified in 
    ASME A112.19.6-1990 but if ANSI revises these requirements, the 
    Secretary shall adopt such revisions if they conform to the basic 
    statutory requirements for test procedures. EPCA, Sec. 323(b)(8), 42 
    U.S.C. Sec. 6293(b)(8). The test procedure requirements for water 
    closets and urinals in ASME/ANSI Standard A112.19.6-1990 have not been 
    revised. DOE proposes to incorporate by reference all applicable 
    sections in ASME/ANSI Standard A112.19.6-1990 for testing water closets 
    and urinals at Appendix T of Title 10 CFR Part 430, Subpart B.
        The test procedures for testing water closets include section 
    7.1.2, ``Test Apparatus and General Instructions;'' and subsections 
    7.1.2.1, 7.1.2.2, 7.1.2.3, and 7.1.6, ``Water Consumption and Hydraulic 
    Characteristics.''
        The test procedures for urinals include sections 8.2, ``Test 
    Apparatus and General Instructions;'' and subsections 8.2.1, 8.2.2, 
    8.2.3, and section 8.5, ``Water Consumption.''
    2. Water Conservation Standards
        EPCA prescribed statutory water conservation standards for faucets, 
    showerheads, water closets and urinals and specified that if specified 
    ASME or ASME/ANSI standards are amended to improve the efficiency of 
    water use, the Secretary shall publish a final rule establishing an 
    amended uniform national standard unless the Secretary determines that 
    adoption of such a standard at the level specified is not (i) 
    technologically feasible and economically justified, (ii) consistent 
    with the maintenance of public health and safety; or (iii) consistent 
    with the purposes of this Act. EPCA, Sec. 325(j) and Sec. 325(k), 42 
    U.S.C. Sec. 6295(j) and Sec. 6295(k).
        (a) Faucets. EPCA specifies that after January 1, 1994, it would be 
    unlawful to manufacture lavatory or kitchen faucets, or lavatory or 
    kitchen replacement aerators that exceed 2.5 gallons per minute (gpm); 
    or metering faucets that exceed 0.25 gallons per cycle, when measured 
    at a flowing water pressure of 80 pounds per square inch (psig). EPCA, 
    Sec. 325(j)(2), 42 U.S.C. Sec. 6295(j)(2). On September 15, 1994, the 
    water conservation standard for faucets was amended to 2.2 gpm at 60 
    psig in ASME/ANSI Standard A112.18.1M-1994.
        At the second workshop held on February 28, 1996, the issue of 
    whether to incorporate the revised ASME/ANSI Standard A112.18.1M-1994 
    was discussed. PMI claimed that all manufacturers are currently 
    designing and manufacturing faucets to be in conformity with this 
    revised standard and therefore, requested that it be incorporated. This 
    position was supported by the workshop participants, including, Mr. R. 
    Michael Martin, the American Water Works Association (AWWA), Delta 
    Faucet Company (Delta), Kohler Company (Kohler), American Standard 
    Inc., and Sloan Valve. Four additional comments submitted following the 
    public meeting reiterated support for incorporation of the 1994 ASME/
    ANSI standard. (PMI, No. 1 at 1; PMI, No. 2 at 2; Eljer, No. 3 at 1; 
    and R. Michael Martin, No. 4 at 1).
        DOE does not believe the revised standard for faucets constitutes 
    an improvement in water efficiency and therefore incorporation of the 
    revised standard would not be necessary. The revised standard (2.2 gpm 
    at 60 psig) is equivalent theoretically to the statutory requirement 
    (2.5 gpm at 80 psig) per Bernoulli's equation of fluid mechanics which 
    states that the ratio of water flow through a fixed orifice at 
    different pressures is equivalent to the square root of the ratio of 
    the pressures.
        However, the Department believes that there might be a burden on 
    the industry if DOE does not incorporate the standard for faucets 
    contained in ASME/ANSI Standard A112.18.1M-1994. Comments indicated 
    that industry is presently designing and manufacturing fixture fittings 
    that meet the flow capacity requirements contained in EPCA and in ASME/
    ANSI Standard A112.18.1M-1994 and the coexistence of both standards 
    would cause confusion in the market place if not brought into 
    conformity. In addition, Mexico and Canada are planning to adopt faucet 
    standards equivalent to those in ASME/ANSI Standard A112.18.1M-1994 so 
    U.S. adoption of that standard would be consistent with the policy of 
    promoting harmonization in North America. Therefore, the Department 
    proposes to incorporate the revised applicable faucet standard in ASME/
    ANSI Standard A112.18.1M-1994 at 10 CFR Sec. 430.32(o) in today's 
    rulemaking.
        (b) Showerheads. EPCA specifies that the maximum water use allowed 
    for any showerhead manufactured after January 1, 1994, is 2.5 gpm when 
    measured at a flowing water pressure of 80 psig. EPCA also requires 
    that such showerheads meet the requirement of ASME/ANSI Standard 
    A112.18.1M-1989, 7.4.3(a). EPCA, Sec. 325(j)(1), 42 U.S.C. 
    Sec. 6295(j)(1). This requirement specifies that if a flow control 
    insert is used as a component part of a showerhead, then it must be 
    manufactured such that a pushing or pulling force of 8 lb or more is 
    required to remove the insert. Note that section 7.4.3(a) in ASME/ANSI 
    Standard A112.18.1M-1989 was redesignated as section 7.4.4(a) in ASME/
    ANSI Standard A112.18.1M-1994.
        The standard for showerheads in ASME/ANSI Standard A112.18.1M-1994 
    are at the level prescribed in EPCA. The proposed rule would codify 
    this standard, 2.5 gpm at 80 psig, in the Code of Federal Regulations 
    and incorporate by reference, section 7.4.4(a) in ASME/ANSI Standard 
    A112.18.1M-1994 at 10 CFR 430.32(p). Codification of this statutory 
    standard does not invoke the requirements specified in section 
    325(j)(3) of EPCA, 42 U.S.C. Sec. 6295(j)(3).
        (c) Water closets and urinals. EPCA specifies that the maximum 
    water use allowed for gravity tank-type toilets, flushometer tank 
    toilets, and electromechanical hydraulic toilets, is 1.6 gallons per 
    flush (gpf), and for blowout toilets and commercial gravity tank-type 
    2-piece toilets is 3.5 gpf, if manufactured after January 1, 1994. For 
    commercial gravity tank-type 2-piece, the maximum water use of 3.5 gpf 
    is applicable until January 1, 1997, after which the standard is 1.6 
    gpf. For flushometer valve toilets, other than blowout toilets, the 
    maximum water use is 1.6 gpf, if manufactured after January 1, 1997. 
    The maximum water use allowed for any urinal manufactured after January 
    1, 1994, is 1.0 gpf. EPCA, Sec. 325(k)(1) and 325(k)(2), 42 U.S.C. 
    Sec. 6295(k)(1) and Sec. 6295(k)(2).
        The standards for water closets and urinals in ASME/ANSI Standard 
    A112.19.6-1990 have not been revised. Accordingly, the proposed rule 
    would codify the statutory water conservation standards for water 
    closets and urinals in 10 CFR Secs. 430.32(q) and 430.32(r), 
    respectively.
    3. Definitions
        EPCA prescribes statutory definitions for terms applicable to the 
    administration of plumbing products.
    
    [[Page 7837]]
    
    DOE believes it would be more convenient for the readers if these 
    definitions were incorporated in the Code of Federal Regulations. 
    Therefore, the proposed rule would incorporate the amended statutory 
    definitions for the terms ``consumer product,'' ``energy conservation 
    standard,'' and ``estimated annual operating cost'' in EPCA, 
    Sec. 321(1), Sec. 321(6) and Sec. 321(7), 42 U.S.C. Sec. 6291(1), 
    Sec. 6291(6) and Sec. 6291(7); and the new statutory definitions for 
    the terms ``ANSI,'' ``ASME,'' ``blowout,'' ``faucet,'' ``flushometer 
    tank,'' ``flushometer valve,'' ``low consumption,'' ``showerhead,'' 
    ``urinal,'' ``water closet,'' and ``water use'' in EPCA, 
    Sec. 321(31)(A)-Sec. 321(31)(H), 42 U.S.C. Sec. 6291(31)(A)-
    Sec. 6291(31)(H), in 10 CFR Sec. 430.2.
    
    B. Supplementary Plumbing Requirements
    
        The proposed provisions to supplement the statutory requirements to 
    facilitate the monitoring and administration of compliance for plumbing 
    products are discussed below.
    1. Metric Equivalents
        Section 205b of the Metric Conversion Act, 15 U.S.C. 205b, states 
    that the metric measurement system is the preferred system of weights 
    and measures in the United States. It also requires Federal agencies to 
    use the metric system of measurement in all procurements, grants, and 
    other business-related activities, except to the extent that such use 
    is impractical or is likely to cause significant inefficiencies or loss 
    of markets to United States firms. These requirements are also 
    expressed in Executive Order 12770 of July 25, 1991. 56 FR 35801 (July 
    29, 1991).
        EPCA specifies that the required labeling for water usage rates of 
    covered plumbing products be expressed in terms of gallons. Metric 
    units are used in the ASME/ANSI Standard A112.18.1M-1994 for testing 
    faucets and showerheads, and are prescribed in ASME/ANSI Standard 
    A112.19.6-1990 for testing water closets and urinals. In addition, they 
    are also required on submissions to the Federal Trade Commission (FTC) 
    concerning labeling.
        To maintain consistency in testing with the ASME/ANSI standards, 
    Section 205(b) of the Metric Conversion Act, and Executive Order 12770, 
    the Department proposes to require the submission of metric equivalents 
    on all plumbing products certified with DOE for compliance purposes.
    2. Definitions of Basic Model
        The Department is proposing to establish definitions of ``basic 
    model'' for plumbing products. It is common for a single plumbing 
    product manufacturer to make numerous models of faucets, showerheads, 
    water closets, and urinals covered by EPCA and each model is 
    potentially required to be tested. Often, however, several models of 
    faucets, for example, are essentially the same faucet except for 
    refinements that do not significantly affect the water consumption of 
    the faucet. One way to meet EPCA's mandate that test procedures ``not 
    be unduly burdensome to conduct,'' is to establish ``basic models'' for 
    plumbing products.
        ``Basic model'' is a term generally used by DOE to describe 
    products or items of equipment with performance, design, hydraulic, and 
    functional characteristics that are essentially the same. For plumbing 
    products, the models that exhibit essentially identical hydraulic 
    characteristics would be categorized into a family. Such a family would 
    constitute a ``basic model'' of that particular covered product and 
    only representative samples within the family need be tested. 
    Components of similar design may be substituted in a basic model 
    without requiring additional compliance certification if the 
    represented measures of water consumption continue to satisfy 
    applicable water usage standards.
        (a) Faucets and showerheads. PMI and American Standard Inc. jointly 
    proposed that ``basic model'' be defined by either (a) the flow control 
    mechanism which is attached or installed within the fixture fitting, or 
    (b) the models that have identical water-passage design features that 
    use the same path of water in the highest-flow mode. (PMI, No. 3, at 
    1).
        R. Michael Martin submitted a comment stating that the proposal by 
    PMI and American Standard Inc. is adequate for faucets but believes 
    additional words are necessary to explain how flow restrictors for 
    showerheads are to be held for testing, because some flow restrictor 
    could be merely a plastic disc with a single hole. (R. Michael Martin, 
    No. 9, at 6).
        The Department disagrees with Mr. Martin's comment on the need for 
    additional language for showerheads. A flow control restrictor for 
    showerheads, such as a plastic disc with a single hole, is not 
    considered to be a separately supplied accessory to be tested by 
    itself. Such a flow control mechanism is internally installed as an 
    integral component and tested within an assembled showerhead.1 
    Thus, DOE believes it unnecessary to add explanatory language as 
    requested by Mr. Martin.
    ---------------------------------------------------------------------------
    
        \1\ Telephonic conversations between Bill Hui, Department of 
    Energy, and Shahin Moinian, Moen Incorporated; Sally Remedios, Delta 
    Faucet Company; and Ken Hair, Price Pfister Incorporated; October 
    19, 1995.
    ---------------------------------------------------------------------------
    
        The Department believes that the ``basic model'' definition for 
    faucets and showerheads proposed by PMI and American Standard Inc. is 
    practical and promotes the objective in Section 323(b)(3) of EPCA, 42 
    U.S.C. Sec. 6293(b)(3). Therefore, the Department proposes to amend the 
    existing definition of ``basic model'' to add language for fixture 
    fittings based on the proposal submitted by PMI and American Standard 
    Inc. in 10 CFR Sec. 430.2.
        (b) Water closets and urinals. PMI and American Standard Inc. also 
    jointly proposed that ``basic model'' for water closets be defined as 
    ``those fixtures which have the largest volume of water within the well 
    of the water closet as flushed by one of the following four types: (a) 
    gravity closed-coupled; (b) gravity one-piece; (c) flushometer tank; or 
    (d) flushometer valves and other pressurized flushing device;'' and 
    ``basic model'' for urinals as ``those fixtures which have the largest 
    volume of water within the well of the urinal.'' (PMI, No. 3, at 1-2; 
    American Standard Inc., No. 4, at 1-2).
        Two comments raised concern about defining ``basic model'' based on 
    the largest volume within the well. Mr. Martin stated, ``Each different 
    size and shape should be a different basic model.'' (R. Michael Martin, 
    No. 9, at 6). The National Institute of Standards and Technology (NIST) 
    stated, ``Manufacturer design, selection and installation of components 
    for control of refill and/or overflow, can differ and may result in 
    higher consumption, rather than lesser, even for a bowl volume that is 
    not the largest.'' (NIST, No. 6, at 2).
        The Department agrees with the view expressed by Mr. Martin and 
    NIST that the proposed definition of ``basic model'' for water closets 
    and urinals by PMI and American Standard Inc. are inadequate because 
    they do not ensure that all water closets and urinals of a particular 
    basic model will have less water usage than the unit(s) with the 
    greatest water volume in the well. For instance, the flush mechanism of 
    a small fixture may permit greater water volume in the well than a 
    large fixture of the same design with a different flush mechanism.
        Therefore, DOE proposes a definition of ``basic model'' for water 
    closets and urinals to mean all units of a given type of covered 
    product (or class thereof) that
    
    [[Page 7838]]
    
    are manufactured by one manufacturer and ``which have hydraulic 
    characteristics that are essentially identical, and which do not have 
    any differing physical or functional characteristics that affect water 
    consumption.''
    3. Statistical Sampling Plans for Certification Testing
        The Department is proposing to establish statistical sampling plans 
    for plumbing products in today's notice. In the case of plumbing 
    products, compliance with water usage standards will be assured in part 
    by having each manufacturer certify that its covered products comply 
    with the applicable water usage standard.
        In promulgating test procedures applicable to certification, one of 
    the major goals is to provide a statistically valid approach so that 
    there is a high probability that products which have been tested and 
    certified as being in compliance with the applicable usage standards 
    actually comply with those standards. Each DOE test procedure 
    incorporates a sampling plan, and that sampling plan is designed to 
    give reasonable assurance that the true mean performance of the product 
    being manufactured and sold meets or conforms to the DOE water usage 
    standard.
        DOE recognizes that units of plumbing products may vary in water 
    usage for a number of valid reasons, including differences in component 
    parts, production and testing. The risk to the public of purchasing a 
    non-complying product, the risk to manufacturers of selling such a 
    product, and the burdens of performing representative testing, are 
    reduced through the application of a statistically meaningful sampling 
    plan and basing the certification decision on the mean water usage 
    performance of the sampled units.
        There are several critical elements of a sampling plan. One is the 
    selection of units for testing. Units must be representative of the 
    product, and be selected randomly from a batch or production lot. 
    Sample size is also a critical element of a sampling plan. The result 
    yielded by water usage performance testing of a product, consisting of 
    tests conducted on a sample of units, will be increasingly more 
    reliable as the size of the test sample increases. This, however, 
    increases the testing burden on the manufacturers. Also, when the 
    variability in performance is greater among individually tested units 
    of a product, the reliability of the test results is less. As a result, 
    DOE's test procedures require sampling plans based on a one-sided 
    confidence limit approach. This approach is designed to minimize the 
    manufacturers' testing burden while ensuring accurate determination of 
    compliance within a specified level of confidence.
        Such statistical sampling plans are specified in section 430.24. 
    The one-sided confidence limit method places either an upper limit or 
    lower limit on the range or interval in which the true mean performance 
    is likely to be found. This method offers added flexibility by allowing 
    for the testing of fewer units and thereby reducing testing costs than 
    would the testing of a fixed number of units.
        The sampling plans utilizing one-sided confidence limits require 
    different statements for the two types of measures of energy 
    consumption. One type of measure includes estimated annual operating 
    cost, energy consumption and other measures of energy consumption for 
    which consumers would favor lower values. The other type of measure 
    includes characteristics such as efficiency, energy factor, and other 
    energy consumption factors for which consumers would favor higher 
    values. In regard to water usage of plumbing products, consumers would 
    favor lower values.
        To determine the measure of water usage to be reported to DOE for 
    compliance certification, the one-sided confidence-limit approach 
    requires that the higher value from either (i) the mean of the sample 
    units or (ii) the upper X percent confidence limit of the true mean 
    divided by Y, be selected. The variable X refers to a confidence limit 
    that ranges from 90-99 percent, and the variable Y refers to a divisor 
    that ranges from 1.01-1.10. The confidence limits would be calculated 
    using generally accepted methods found in statistics textbooks, based 
    on the sample mean and sample standard deviation. DOE views the latter 
    calculation as being a one-sided confidence interval using t-
    statistics, with the divisor constituting a ``derating'' factor. The 
    derating factor was included to take into account variability in the 
    performance or efficiency of products due to many factors, including 
    manufacturing variability and variations in the material. Furthermore, 
    this format (confidence limits divided by a derating factor) is similar 
    to the format required for other appliance products for which DOE 
    requires testing.
        PMI and American Standard Inc. proposed an alternate sampling plan 
    for testing fixture fittings and fixtures based on testing two samples 
    selected at random first, and then eight additional samples if either 
    of the two samples exceeds the maximum water consumption. The average 
    of all eight of the samples shall not exceed the requirements of EPCA. 
    (PMI, No. 3, at 2; American Standard Inc., No. 4, at 2-3).
        AWWA, New York State Department of Environmental Conservation 
    (NYSDEC), NIST, and Mr. R. Michael Martin claimed that the results of a 
    sampling plan based on a sample size of two units may not be 
    statistically accurate and therefore opposed the above proposal. (AWWA, 
    No. 2, at 1; NYSDEC, No. 5, at 4; NIST, No. 6, at 2; and R. Michael 
    Martin, No. 9, at 5).
        The Department agrees with the views expressed by AWWA, NYSDEC, 
    NIST, and Mr. Martin that the two-unit sampling plan is statistically 
    unreliable. For this reason and to maintain consistency with the 
    existing DOE statistical sampling plans, the Department is proposing to 
    utilize the one-sided confidence limit approach.
        (a) Sampling plan for water closets and urinals utilizing one-sided 
    confidence limits. AWWA and NYSDEC supported use of DOE's approach. 
    AWWA stated there exists a ``high variability in the manufacture of 
    porcelain toilets and urinals'' while NYSDEC stated that ``variation of 
    manufacture of vitreous china'' warrants recognition. Therefore, they 
    proposed a one-sided confidence limit statistical sampling plan for 
    fixtures at 90%. (AWWA, No. 2, at 1; and NYSDEC, No. 5, at 4).
        PMI stated that if DOE's approach of utilizing a one-sided 
    confidence limit is to be used, the industry would support a confidence 
    limit of 90% only if a corresponding divisor of 1.10 is allowed. (PMI, 
    No. 2, at 1). To support its proposal, PMI submitted data indicating 
    that testing at such level (90% at 1.10) would allow manufacturers to 
    certify compliance with no more than four units whereas five units 
    would be required if a more stringent level (90% at 1.05) was imposed 
    instead.
        DOE agrees with AWWA and NYSDEC that there is high variability in 
    the manufacturing of virtreous china that would justify a confidence 
    limit at 90%. DOE also agrees with PMI that a divisor lower than 1.10 
    would cause manufacturers additional expense while providing no 
    additional assurances that the products tested are meeting the 
    requirement of the law. PMI's proposal would minimize manufacturers'' 
    test burden while at the same time provide an adequate level of 
    confidence that products certified to be in compliance are actually in 
    compliance with applicable water conservation
    
    [[Page 7839]]
    
    standards. Therefore, the Department proposes to adopt in a statistical 
    sampling plan for fixtures utilizing one-sided confidence limits based 
    on the following statistical parameter (90% confidence limits with a 
    1.10 divisor) at 10 CFR Secs. 430.24(u) and (v).
        (b) Sampling plan for faucets and showerheads utilizing one-sided 
    confidence limits. AWWA and NYSDEC claimed that faucets and showerheads 
    can be manufactured to tighter tolerances than vitreous china and 
    proposed a statistical sampling plan that utilized a higher one-sided 
    confidence limits and corresponding divisor. (AWWA, No. 2, at 1: and 
    NYSDEC, No. 5, at 4).
        DOE recognizes that fixture fittings are typically metal-based 
    (e.g., chrome and brass), which means that they can be machined to much 
    greater precision and tolerances, and which in turn, warrants a higher 
    confidence limits and corresponding derating factor as suggested by 
    AWWA. Although DOE agrees that fixture fittings warrant a higher 
    confidence limit and corresponding divisor than vitreous china, the 
    Department believes that a statistical sampling plan at the apex level 
    (99% confidence limits, 1.01 divisor (i.e., 1 percent 
    tolerance))--the level typically employed for products that demonstrate 
    low manufacturing variability--may result in a testing burden. The 
    Department believes a statistical sampling plan at the following 
    parameter (95% confidence limits, 1.05 divisor (5 percent 
    tolerance)) may be more appropriate and reasonable for manufacturers to 
    meet. In written comments following the February 28, 1996 public 
    meeting, PMI stated that industry would support this statistical 
    sampling plan for fixture fittings (faucets and showerheads). (PMI, No. 
    2, at 1). Moreover, Moen Incorporated submitted data indicating that 
    testing at such level would allow it to certify compliance with no more 
    than two units.
        Based on the above considerations, the Department proposes to adopt 
    in a statistical sampling plan for fixture fittings utilizing one-sided 
    confidence limits at the following statistical parameter (95% 
    confidence limits with a 1.05 divisor) at 10 CFR Secs. 430.24(s) and 
    (t). DOE believes this sampling plan will minimize test burden on 
    manufacturers while at the same time provide an adequate level of 
    confidence that products certified to be in compliance are actually in 
    compliance with applicable water conservation standards.
    4. Modifications to Existing Language To Include Plumbing Products in 
    the Code of Federal Regulations
        Sections 430.27, 430.31-430.33, 430.40, 430.41, 430.47, 430.49, 
    430.50, 430.60, 430.61, 430.63, 430.70(a)(1), and 430.73 of Title 10 of 
    the CFR currently do not address the monitoring and administration of 
    plumbing products in the DOE Appliance Standards Program. The 
    Department proposes to amend these sections in the Code of Federal 
    Regulations to extend coverage to plumbing products covered by EPCA.
    5. Definition for ``Electromechanical Hydraulic Toilet''
        EPCA specifies the water conservation standard for 
    ``electromechanical hydraulic toilets'' at 1.6 gallon per flush. EPCA, 
    Sec. 325(k)(1)(A), 42 U.S.C. Sec. 6295(k)(1)(A). However, the term 
    ``electromechanical hydraulic toilets'' is undefined. The Department 
    proposes to establish a definition for this term. PMI proposed that 
    ``electromechanical hydraulic toilets'' be defined as ``any water 
    closet that utilizes electrically operated devices, such as, but not 
    limited to, air compressors, pumps, solenoids, motors, or macerators in 
    place of, or, to aid gravity in evacuating waste from the toilet 
    [bowl].'' (PMI, No. 15, at 1).
        The definition proposed by PMI provides an acceptable description 
    of the term ``electromechanical hydraulic toilet.'' Therefore, the 
    Department proposes to include this definition for ``electromechanical 
    hydraulic toilets'' in 10 CFR Sec. 430.2.
    6. Certification Reporting Requirements for Plumbing Products
        (a) Types of information. Section 430.62(a)(2) of Title 10 of CFR 
    currently requires manufacturers of covered residential products to 
    submit, for each basic model, certain types of data and information in 
    their certification reports to the Department. Plumbing products were 
    added as covered products under EPCA, but presently certification 
    requirements do not exist for plumbing products. The Department 
    proposes to establish certification reporting requirements for faucets, 
    showerheads, water closets, and urinals.
        PMI proposed to produce a product directory for submission to DOE 
    which would include the following information: (a) product category, 
    (b) model number of product, (c) water use level, (d) name and address 
    of manufacturer, (e) name and phone number of contact at manufacturer, 
    and (f) compliance statement. (PMI, No. 3, at 2).
        The Department presently requires similar types of information for 
    certification from manufacturers of residential products and thus 
    believes such types of information from plumbing manufacturers would be 
    reasonable and appropriate. Therefore, DOE proposes to include in 
    proposed 10 CFR Sec. 430.62(a)(4) language requiring that the 
    certification report for each basic model shall include the product 
    type, product class, manufacturer's name, private labeler name(s) if 
    applicable, the manufacturer's model number(s), and the water usage.
        (b) Precision level of reported test results. PMI raised an issue 
    at the February 28, 1996, public meeting regarding the level of 
    precision (number of digits after the decimal place) required on final 
    results for certifying compliance and requested that DOE provide such 
    clarification in today's rulemaking.
        DOE stated that Sections 325(j) and 325(k) of EPCA, 42 U.S.C. 
    Sec. 6295(j) and Sec. 6295(k), specified maximum standard levels for 
    faucets, showerheads, water closets, and urinals in terms of tenth of a 
    gallon, or in the case of metering faucets, hundredth of a gallon. 
    Thus, the Department believes that those levels should be observed in 
    certifying compliance.
        (c) Mathematical rounding procedures. PMI raised a second issue 
    regarding mathematical rounding procedures, and how such procedures are 
    to be used to convert test data into final results for the purpose of 
    determining compliance. PMI stated that the industry subscribes to the 
    rounding rules contained in ASME Guide SI-1, ASME Orientation and Guide 
    for use of SI (metric) units (9th Edition, 1982), and recommended that 
    DOE adopt these rounding rules. NIST raised a concern that the ASME 
    rules would allow a number to be rounded such that it may potentially 
    exceed a fixed statutory standard. (PMI, transcript, at 35; NIST, 
    transcript, at 35-36)
        The Department agrees that, based on the concern identified by 
    NIST, it would be inappropriate to adopt the ASME rounding rules as 
    requested to be used to convert test data into final results for the 
    purpose of determining compliance. Instead, DOE proposes the following 
    basic rounding rules: Five and above round up, and less than five, 
    round down. Such rounding rules are to be applied after the final 
    result is calculated.
        R. Michael Martin and Kohler supported DOE's view that the basic 
    rounding rules should be used to determine compliance with the EPCA's
    
    [[Page 7840]]
    
    water use standards. (R. Michael Martin, transcript, at 40; Kohler, 
    transcript, at 41). PMI stated that the industry would support DOE's 
    proposed mathematical rounding rules. (PMI, No 2, at 1).
        The Department believes the proposed basic rounding rules are 
    practical and appropriate because they are consistent with conventional 
    rounding methods. In addition, DOE believes the proposed approach in 
    applying the basic rounding rules is appropriate to ensure that 
    consistency is maintained in converting test data into final results 
    for the purpose of determining compliance.
        (d) Effective date for initial compliance certification 
    submissions. Section 430.62(a) states, ``Each manufacturer or private 
    labeler before distributing in commerce any basic model of a covered 
    product subject to the applicable energy conservation standard set 
    forth in Subpart C of this part shall certify by means of a statement 
    of compliance and certification report that each basic model meets the 
    requirement of that standard,'' and section 430.62(b) adds, ``all data 
    required by paragraph 430.62(a) of this section shall be submitted on 
    or before the effective date of the applicable energy conservation 
    standard as prescribed in Section 325 of the Act.''
        The Department's regulations authorize imposition of penalties, 
    consistent with EPCA, for failure to make reports or provide 
    information required to be supplied by the Act or Title 10 CFR Part 
    430. 10 CFR Sec. 430.61(a)(1) and (b). Any person who knowingly 
    violates the compliance certification requirements may be subject to 
    assessment of a civil penalty of no more than $100 for each violation, 
    and each day of noncompliance shall constitute a separate violation. 10 
    CFR Sec. 430.61(b).
        Such submissions as described are required only after certification 
    reporting requirements are promulgated for a covered product. DOE is 
    proposing certification reporting requirements (see discussion in (a) 
    of this subsection) in today's notice that when promulgated, would 
    subject plumbing products, for which standards became effective January 
    1, 1994, to the requirements specified in sections 430.62(a)-(b).
        American Standard Inc. raised a concern at the public meeting on 
    February 28, 1996, that manufacturers who produce larger inventories 
    have more models to test, that testing of certain products such as 
    water closets are extremely labor-intensive and time-consuming, and 
    therefore it would be unreasonable to expect manufacturers to be able 
    to meet the certification requirements. American Standard Inc. 
    recommended that DOE postpone for one year the effective date for the 
    initial compliance certification submissions, which was also supported 
    by Kohler and PMI . (American Standard Inc., transcript, at 62; Kohler, 
    transcript, at 66; PMI, No. 2, at 2).
        DOE agrees with American Standard Inc. that certain manufacturers 
    may be overly burdened by the task of testing to meet the compliance 
    certification requirements once such requirements are promulgated. The 
    Department believes that a delay of the effective date for one year, as 
    recommended by manufacturers, would allow a reasonable amount of time 
    for plumbing manufacturers to complete required testing and submit the 
    initial compliance certification reports. Therefore, the Department 
    would require, in proposed 10 CFR Sec. 430.62(a)(2), the initial 
    certification submissions for plumbing products not later than one year 
    following the publication of a final rule.
    7. Faucet Standards on Multiple-User Sprayheads.
        A manufacturer asked whether sprayheads are covered products under 
    EPCA. Sprayheads are fixture fittings that are installed in lavatories 
    (known as washfountains or wash sinks) for multiple users. They have 
    multiple orifices that can independently or collectively actuate (by 
    pneumatic hand or foot control, mechanical metering or infrared 
    metering control) and may be considered a type of ``faucet'' subject to 
    the applicable water conservation standard. EPCA defines the term 
    ``faucet'' to mean ``a lavatory faucet, kitchen faucet, metering 
    faucet, or replacement aerator for a lavatory or kitchen faucet.'' 
    EPCA, Sec. 321(31)(E), 42 U.S.C. Sec. 6291(31)(E). However, EPCA does 
    not further define lavatory faucets, kitchen faucets, metering faucets, 
    lavatory replacement aerators, and kitchen replacement aerators.
        DOE proposes to clarify whether sprayheads are covered product, and 
    if so, how the faucet standards are to apply to ``sprayheads.''
        (a) Sprayheads as covered products. Bradley Corporation (Bradley) 
    recommended that the definition for ``faucet'' in Section 321(31)(E) of 
    EPCA, 42 U.S.C. Sec. 6291(31)(E), be amended to mean ``a lavatory 
    faucet, kitchen faucet, metering faucet, or replacement aerator for a 
    lavatory or kitchen faucet, except that such term does not include 
    multiple-user type fixtures.'' (Bradley, No.1, at 1-2).
        R. Michael Martin stated that the term ``faucet'' is defined in 
    Section 321(31)(E) of EPCA, 42 U.S.C. Sec. 6291(31)(E), and that the 
    term ``lavatory faucet,'' although not defined in the statute, the 
    regulations, or ASME A112.18.1, is defined in the California 
    regulations as a ``plumbing fitting designed to discharge into a 
    lavatory.'' Mr. Martin also stated that numerous complying sprayhead-
    installed washfountains are currently listed in the California 
    database. For these reasons, Mr. Martin believes that sprayheads are 
    not exempt, and considers them to be a form of lavatory faucet and 
    therefore a covered product. (R. Michael Martin, No. 9, at 7).
        The Department has considered Bradley's recommendation, but does 
    not have the authority to amend the statutory definition for faucet in 
    Section 321(31)(E) of EPCA, 42 U.S.C. Sec. 6291(31)(E). Moreover, DOE 
    agrees with Mr. Martin's view that sprayheads are a form of lavatory 
    faucet and thus can be considered a covered product. DOE believes that 
    any faucet or replacement aerator used in a kitchen or lavatory 
    capacity, or any faucet, when turned on, that gradually shuts itself 
    off after a programmed period (metered), regardless of physical shape 
    or design features, shall constitute a covered ``faucet'' subject to 
    the water performance requirements of Section 325(j) of EPCA, 42 U.S.C. 
    Sec. 6295(j).
        (b) Application of faucet standards to sprayheads with 
    independently-controlled orifices. The Department is proposing that 
    sprayheads be considered a covered product and that they be subject to 
    the applicable faucet standards. Sprayheads with multiple orifices can 
    be independently actuated by manual on/off or metering controls. EPCA 
    prescribes a water use standard at 2.5 gpm at 80 psig for lavatory 
    faucets and 0.25 gallons per cycle at 80 psig for metering faucets. 
    EPCA, Sec. 325(j)(2), 42 U.S.C. Sec. 6295(j)(2). The Department 
    believes that each independent orifice that manually turns on or off 
    constitutes a separate ``lavatory faucet'' by itself subject to the 
    applicable water usage standard for lavatory faucets. Moreover, DOE 
    believes that each independent orifice of a sprayhead that actuates to 
    deliver a pre-set volume of water before gradually shutting itself off 
    constitute a separate ``metering faucet'' by itself subject to the 
    applicable water usage standard for metering faucets.
        Therefore, DOE proposes to include clarifying language to the 
    lavatory and metering faucet standards, in 10 CFR Sec. 430.32(o), to 
    the effect that each orifice, depending on its mode of actuation, shall 
    not exceed the
    
    [[Page 7841]]
    
    maximum flow rate for a lavatory or metering faucet.
        (c) Application of faucet standards to sprayheads with 
    collectively-controlled orifices. Sprayheads can be also centrally 
    controlled such that all available orifices collectively actuate upon 
    demand. The total water flow of a collectively-actuated sprayhead is 
    dependent on the number of users at the lavatory in which the sprayhead 
    is installed. This number is determined by the number of component 
    lavatories that, based on the capacity criterion of a plumbing code, 
    make up a single lavatory. DOE believes the maximum flow rate of such a 
    sprayhead should be prorated by the number of users or component 
    lavatories.
        However, a lavatory may be defined to be equivalent to a different 
    number of component lavatories depending on the following plumbing 
    codes: (a) the Standard Plumbing Code,2 (b) the Uniform Plumbing 
    Code,3 (c) the National Standard Plumbing Code,4 (d) the 
    National Plumbing Code,5 and (e) the International Plumbing 
    Code.6

        The 1991 Standard Plumbing Code, Section 916.1, states, ``Each 18 
    inches of wash sink circumference (circular type) shall be equivalent 
    to one lavatory.'' The 1991 Uniform Plumbing Code, Appendix C (No. 8), 
    states, ``Twenty-four (24) lineal inches (609.6 mm) of wash sink or 
    eighteen (18) inches (457.2 mm) of a circular basin, when provided with 
    water outlets for such space, shall be considered equivalent to one (1) 
    lavatory.'' The 1993 National Standard Plumbing Code, Section 7.18, 
    states, ``Each eighteen inch unit of usable length of a rim of a 
    multiple use lavatory shall be considered equivalent to one lavatory as 
    it affects the drainage and water supply piping sizes and fixture usage 
    requirements, provided hot and cold or tempered water is available for 
    each eighteen inch interval.'' The 1993 National Plumbing Code, Section 
    P.1217.1, and the 1995 International Plumbing Code, Section 417.1, both 
    state, ``Every 20 inches (508 mm) of rim space shall be considered as 
    one lavatory.''
        DOE believes it is necessary to establish a single capacity 
    criterion to be applicable for all lavatories. Based on the 
    considerations of all plumbing codes, the Department believes the 
    capacity criterion defined in Section P.1217.1 of the 1993 National 
    Plumbing Code, and Section 417.1 of the 1995 International Plumbing 
    Code for wash sinks (i.e., every 20 inches (508 mm) of rim space shall 
    be considered as one lavatory) would be more versatile to lavatories of 
    various physical configurations and temperature requirements.
        Therefore, DOE proposes to include clarifying language with the 
    lavatory and metering faucet standards, in 10 CFR Sec. 430.32(o), to 
    the effect that: (1) the maximum flow rate of a collectively actuated 
    multiple-orifice sprayhead that manually turns on or off shall be the 
    product of (a) the maximum flow rate for a lavatory faucet and, (b) the 
    number of component lavatories (rim space of the lavatory in inches 
    (millimeters) divided by 20 inches (508 millimeters)) and, (2) the 
    maximum flow rate of a collectively actuated multiple-orifice sprayhead 
    that delivers a pre-set volume of water before gradually shutting 
    itself off shall be the product of (a) the maximum flow rate for a 
    metering faucet and, (b) the number of component lavatories (rim space 
    of the lavatory in inches (millimeters) divided by 20 inches (508 
    millimeters)).
    8. Enforcement
        Several commenters raised the issue of enforcement of plumbing 
    products regulations. AWWA recommended that DOE establish: (a) a 
    protocol for verifying industry compliance with EPCA; (b) a non-
    compliance warning system that gives violators of EPCA an opportunity 
    for corrective actions to avoid enforcement sanctions; and (c) a 
    product certification and listing program to improve EPCA compliance 
    and minimize the need for future enforcement actions against the 
    plumbing industry. (AWWA, No. 8, at 24).
        Seattle Water Department requested rules for enforcement of the 
    national standards (particularly for imported products) and penalties 
    for manufacture of non-conforming products. It believes the retail 
    marketplace is currently full of nonconforming plumbing products which 
    is unfair to complying manufacturers while robbing consumers and the 
    nation of much needed long term water and energy savings. (Seattle 
    Water Department, No. 7, at 4).
        The Department agrees enforcement of the standards is necessary to 
    ensure compliance of all covered products. The Department currently has 
    an enforcement procedure at sections 430.70-430.75 and Appendix B of 
    Title 10 CFR Part 430, Subpart F which the Department is proposing to 
    amend, where appropriate, to include plumbing products. DOE may use 
    these procedures to assess civil penalties under Section 333 of EPCA, 
    42 U.S.C. 6303. In actions involving small businesses, DOE will be 
    guided by the small entity enforcement policy it is required to adopt 
    by Section 223 of the Small Business Regulatory Enforcement Fairness 
    Act of 1996 (Pub. L. 104-121, Title II, Sec. 223).
        DOE believes that its existing enforcement procedures--which 
    encourage industry policing, prescribe enforcement testing, and provide 
    for civil penalties for all covered consumer products (which include 
    imports) that violate the Federal standards--are adequate for deterring 
    would-be violators. The Department believes that it is not necessary 
    for it to adopt a product certification and listing to improve EPCA 
    compliance. PMI is planning to produce a product directory which will 
    list manufacturers and plumbing products conforming to EPCA. Such a 
    product directory, maintained by PMI and supported by industry, would 
    be valuable to assist consumers and others in identifying plumbing 
    products that comply or do not comply with EPCA.
    
    C. Clarification of Certification Reporting Requirements for 
    Residential Appliances
    
        DOE proposes to redesignate, revise existing language, and add new 
    language and paragraphs as necessary in the CFR sections dealing with 
    certification and enforcement requirements for all residential 
    appliances.
        The amendments and revisions proposed for Part 430 of Title 10 of 
    the CFR are as follows:
        1. Section 430.62(a) is redesignated as 430.62(a)(1), and revised 
    to include the DOE address to be used for compliance certification 
    reporting.
        2. Section 430.62(a), ``Compliance Certification'' is added as a 
    new section heading.
        3. Section 430.62(a)(1) is redesignated as 430.62(a)(3).
        4. Section 430.62(a)(2) is redesignated as 430.62(a)(4) and revised 
    by:
        (a) rearranging, alphabetically, the certification reporting 
    requirements for refrigerators, refrigerator-freezers and freezers, 
    water heaters, room air conditioners, central air conditioners and 
    central air conditioning heat pumps, pool heaters, furnaces, direct 
    heating equipment, general service
    
    [[Page 7842]]
    
    fluorescent lamps and incandescent reflector lamps;
        (b) amending the certification report to add, alphabetically, 
    absent reporting requirements for kitchen ranges, ovens and microwave 
    ovens, dishwashers, clothes washers and clothes dryers; and
        (c) adding, alphabetically, new certification reporting 
    requirements for faucets, showerheads, water closets, and urinals. [see 
    discussion in section II(B)(6)(a)]
        5. A new section, 430.62(a)(2), is added to provide a one-year 
    delay of the effective date for compliance certification by 
    manufacturers of faucets, showerheads, water closets, and urinals. [see 
    discussion in section II(B)(6)(d)]
        6. Section 430.62(a)(3) is redesignated as 430.62(a)(5), and 
    referenced paragraph ``(a)(2)'' within the new section is redesignated 
    as paragraph ``(a)(4).''
        7. Section 430.62(b), ``Initial Reporting Requirements,'' is 
    deleted.
        8. Section 430.62(c), ``New Models,'' is redesignated as 430.62(b), 
    and amended by redesignating the referenced paragraph ``(a)(2)'' as 
    paragraph ``(a)(4),'' and adding appropriate language to include 
    plumbing products, and a mailing address to be used for submitting new 
    model information.
        9. A new section, 430.62(c), ``Discontinued Models,'' is added to 
    specify the information required to be submitted to DOE when models are 
    discontinued.
        10. Section 430.62(d), ``Maintenance of Records,'' is amended by 
    adding appropriate language to include plumbing products.
        11. Section 430.62(e), ``Third Party Representation,'' is amended 
    by redesignating the referenced paragraph ``(a)'' to ``(a)(4)'', and 
    adding language allowing third party representatives to submit 
    discontinued model information on behalf of an authorizing 
    manufacturer.
        12. A new section, 430.62(f), ``Amendment of Information,'' is 
    added to expressly require manufacturers to submit revised compliance 
    certification if any information contained in the prior submission has 
    changed.
        13. Section 430.70(a)(3), ``Sampling,'' is amended by adding 
    appropriate language to include plumbing products.
        14. Section 430.70(a)(6)(i), ``Testing at Manufacturer's Option,'' 
    is amended by adding appropriate language to include plumbing products.
        15. Appendix A to Subpart F, Title 10 CFR Part 430, is amended by 
    adding language to include plumbing products; to identify the third 
    party organization officially acting as representative of the 
    manufacturer; and to include, as an attachment, a uniform format for 
    certification reports on new basic models of a covered products.
        16. Appendix B to Subpart F, Title 10 CFR Part 430 is amended to 
    correct typographical errors and add appropriate language to include 
    plumbing products.
        The Department believes these proposed amendments and additions are 
    necessary and appropriate and will clarify the certification and 
    enforcement requirements for all residential products.
    
    III. Procedural Requirements
    
    A. Review Under the National Environmental Policy Act of 1969
    
        In this rule, the Department proposes provisions to implement 
    statutorily mandated water conservation standards and test procedures 
    for faucets, showerheads, water closets, and urinals. Implementation of 
    this rule would not result in environmental impacts. The Department has 
    therefore determined that this rule is covered under the Categorical 
    Exclusion found at paragraph A.6 of appendix A to subpart D, 10 CFR 
    Part 1021, which applies to the establishment of procedural 
    rulemakings. Accordingly, neither an environmental assessment nor an 
    environmental impact statement is required.
    
    B. Review Under Executive Order 12866, ``Regulatory Planning and 
    Review''
    
        This regulatory action is not a significant regulatory action under 
    Executive Order 12866, ``Regulatory Planning and Review,'' October 4, 
    1993. Accordingly, this action was not subject to review under the 
    Executive Order by the Office of Information and Regulatory Affairs.
    
    C. Review Under the Regulatory Flexibility Act
    
        The Regulatory Flexibility Act, 5 U.S.C. Sec. 603, requires the 
    preparation of an initial regulatory flexibility analysis for every 
    rule which by law must be proposed for public comment, unless the 
    agency certifies that the rule, if promulgated, will not have a 
    significant economic impact on a substantial number of small entities. 
    A regulatory flexibility analysis examines the impact of the rule on 
    small entities and considers alternative ways of reducing negative 
    impacts.
        The Department used the small business size standards published on 
    January 31, 1996 by the Small Business Administration to determine 
    whether any small entities would be required to comply with this 
    proposed rule. 61 FR 3280 (to be codified at 13 CFR part 121). The size 
    standards are listed by Standard Industrial Classification (SIC) code 
    and industry description. Plumbing fixtures (water closets and urinals) 
    manufacturing is listed under the following SIC codes: (1) SIC 3088 
    (plastic plumbing fixtures), (2) SIC 3261 (vitreous china plumbing 
    fixtures), and (3) SIC 3431 (enameled iron, cast iron, and pressed 
    metal plumbing fixtures). Plumbing fixture fittings (faucets and 
    showerheads) manufacturing is SIC 3432. To be considered a small 
    business, a manufacturer of plastic plumbing fixtures, vitreous china 
    plumbing fixtures, enameled iron, cast iron, and pressed metal plumbing 
    fixtures, or plumbing fixture fittings and its affiliates may employ a 
    maximum of 500, 750, 750, or 500 employees, respectively.
        The Department estimates there are approximately 32 domestic firms 
    and 38 foreign firms which manufacture either plastic, vitreous china, 
    or enameled iron, cast iron, and pressed metal plumbing fixtures, or a 
    combination of the three various types of plumbing fixtures. DOE also 
    estimates there are 57 domestic firms and 30 foreign firms which 
    manufacture plumbing fixture fittings covered under EPCA.7 Some 
    domestic manufacturers of plumbing fixtures also manufacture plumbing 
    fixture fittings. Moreover, many domestic manufacturers of plumbing 
    fixtures and fixture fittings are affiliated with larger U.S. firms. 
    The sizes of plumbing fixtures manufacturing companies and their 
    affiliates in the U.S. range from 50 employees to 54,298 employees, and 
    for plumbing fixture fittings manufacturing companies and their 
    affiliates, they range from 50 employees to 51,300 employees. The 
    Department estimates there are five to seven firms in the United States 
    that both manufacture plumbing fixtures covered by EPCA, and have, 
    together with their affiliates, 750 or fewer employees. DOE estimates 
    that there are approximately 7 firms in the United States that both 
    manufacture plumbing fixture fittings covered by EPCA, and have, 
    together with their affiliates, 500 or fewer employees.

        EPCA prescribes water conservation standards for faucets, 
    showerheads, water closets, and urinals. The statutory water 
    conservation standards are incorporated in the proposed rule, although 
    the standards do not depend
    
    [[Page 7843]]
    
    on rulemaking for their implementation. The Act also requires DOE to 
    prescribe test procedures for measuring water consumption, and it 
    further requires the use of the test procedures in ASME/ANSI Standards 
    A112.18.1M-1989 (for faucets and showerheads) and A112.19.6-1990 (for 
    water closets and urinals). If the water conservation standards or the 
    test procedures for water consumption are amended by ASME and approved 
    by ANSI, DOE is required to amend its standards or test procedures 
    accordingly unless to do so would not meet certain statutory criteria 
    for standards or test procedures. The standard for faucets and test 
    procedures for faucets and showerheads were amended on September 15, 
    1994 in ASME/ANSI Standard A112.18.1M-1994, and DOE is now proposing to 
    incorporate in the CFR ASME/ANSI Standard A112.18.1M-1994.
        DOE believes that complying with the proposed rule (excluding the 
    cost of compliance with the water conservation standards and test 
    procedures directly imposed by EPCA) would not impose significant 
    economic costs on a substantial number of small manufacturers. The test 
    procedure mandated by EPCA (in ASME/ANSI Standard A112.19.6-1990) and 
    that which is proposed to be incorporated by DOE (in ASME/ANSI Standard 
    A112.18.1M-1994) are test procedures already in general use in the 
    industry. Manufacturers contacted by the Department stated that they 
    currently test faucets and showerheads in accordance with ASME/ANSI 
    Standard A112.18.1M-1994, and water closets and urinals in accordance 
    with ASME/ANSI Standard A112.19.6-1990.
        The proposed rule has been drafted to minimize the burden of 
    testing for all manufacturers, and DOE has relied heavily on 
    recommendations that have been provided by the plumbing products trade 
    association, their member companies and other water conservation 
    organizations. The proposed statistical sampling procedures are based 
    on statistical sampling procedures established for consumer appliance 
    products at 10 CFR Sec. 430.24, and recommendations submitted by the 
    Plumbing Manufacturers Institute (PMI), American Water Works 
    Association (AWWA), and New York State Department of Environmental 
    Conservation (NYSDEC). The sampling procedures are designed to keep the 
    testing burden on manufacturers as low as possible, while still 
    providing confidence that the test results of units tested can be 
    applied to units of the same basic model. The proposed compliance 
    reporting requirements are based on recommendations from PMI and are 
    consistent with the requirements for consumer appliance products at 10 
    CFR Sec. 430.62.
        DOE recognizes that some manufacturers may not be able to certify 
    compliance immediately following publication of the DOE final rule. 
    Such submissions generally are required before a basic model is allowed 
    to be distributed in commerce. 10 CFR Sec. 430.62(a). The proposed rule 
    eases the burden of compliance for manufacturers of faucets, 
    showerheads, water closets, and urinals, including small manufacturers, 
    by providing that the certification reporting requirements for initial 
    submissions would not take effect until 12 months after the publication 
    of the final rule.
        The Department invites public comment on its conclusion that the 
    costs of complying with the proposed rule would neither affect a 
    substantial number of small businesses, nor impose a significant 
    economic impact on such businesses.
    
    D. Review Under Executive Order 12612, ``Federalism''
    
        Executive Order 12612, ``Federalism,'' 52 FR 41685 (October 30, 
    1987), requires that regulations, rules, legislation, and any other 
    policy actions be reviewed for any substantial direct effect on States, 
    on the relationship between the National Government and States, or in 
    the distribution of power and responsibilities among various levels of 
    government. If there are substantial effects, then the Executive Order 
    requires preparation of a federalism assessment to be used in all 
    decisions involved in promulgating and implementing a policy action.
        The proposed rules published today would not regulate the States. 
    They primarily would affect the manner in which DOE promulgates 
    residential and commercial products, water conservation standards, test 
    procedures, and certification of compliance by manufacturers, 
    prescribed under the Energy Conservation and Policy Act. State 
    regulation in this area is largely preempted by the Energy Policy and 
    Conservation Act. The proposed rules published today would not alter 
    the distribution of authority and responsibility to regulate in this 
    area. Accordingly, DOE has determined that preparation of a federalism 
    assessment is unnecessary.
    
    E. Review Under Executive Order 12630, ``Governmental Actions and 
    Interference with Constitutionally Protected Property Rights''
    
        It has been determined pursuant to Executive Order 12630, 
    ``Governmental Actions and Interference with Constitutionally Protected 
    Property Rights,'' 52 FR 8859 (March 18, 1988), that this regulation 
    would not result in any takings which might require compensation under 
    the Fifth Amendment to the United States Constitution.
    
    F. Review Under the Paperwork Reduction Act
    
        Today's Notice of Proposed Rulemaking would revise compliance 
    certification requirements applicable to manufacturers of covered 
    consumer products that were previously approved by the Office of 
    Management and Budget (OMB). These proposed collections of information 
    have been submitted to the Office of Management and Budget for review 
    and approval under the Paper Reduction Act, 44 U.S.C. 3501, et seq.
        Appendix A to Subpart F of Part 430, ``Compliance Statement,'' was 
    previously approved by OMB and assigned OMB Control No. 1910-1400. The 
    proposed rule would revise this form to cover certification of plumbing 
    products; facilitate use of the form by third party representatives of 
    covered product manufacturers; and, in an attachment, specify the 
    format of the certification report that manufacturers currently are 
    required to submit to DOE by 10 CFR part 430.62(a)(2). The revisions to 
    appendix A to subpart F will make the compliance certifications more 
    uniform and easier to complete. DOE estimates there will be no 
    additional burden associated with these changes to the certification 
    statement and certification report requirements in Part 430.
        The proposed rule would require manufacturers of plumbing products 
    to maintain records concerning their determinations of the water 
    consumption of faucets, showerheads, water closets and urinals. DOE has 
    concluded that this recordkeeping requirement is necessary for 
    implementing and monitoring compliance with the water conservation 
    standards, testing and certification requirements for residential and 
    commercial faucets, showerheads, water closets and urinals mandated by 
    EPCA.
        The proposed rule also requires manufacturers to submit initial 
    certification reports for basic models of covered faucets, showerheads, 
    water
    
    [[Page 7844]]
    
    closets and urinals within 12 months after the publication of a final 
    rule in the Federal Register. The initial certification reports would 
    be a one-time submission stating that the manufacturer has determined 
    by employing actual testing that the basic model of faucet, showerhead, 
    water closet or urinal meets the applicable water conservation 
    standard. After the first year, manufacturers of plumbing products 
    would have to submit a certification report for each new basic model, 
    or to certify compliance with a new or amended standard, before the 
    model would be allowed to be distributed in commerce.
        DOE estimates the number of covered manufacturing firms of plumbing 
    fixtures to be approximately 70. DOE estimates the number of hours 
    required to comply with the reporting and recordkeeping requirements in 
    the proposed rule, after the initial year of compliance, to be 
    approximately 4 to 16 hours per year per firm. The total annual 
    reporting and recordkeeping burden on manufacturers of plumbing 
    fixtures to comply with the proposed rule is expected to be from 280 to 
    1120 hours (70 x 4-16 hours per year). DOE estimates the number of 
    covered manufacturing firms of plumbing fixture fittings to be 
    approximately 87, and the number of hours required to comply with the 
    reporting and recordkeeping requirements in the proposed rule to be 
    approximately 4 to 8 hours per year per firm. The total annual 
    reporting and recordkeeping burden on manufacturers of plumbing fixture 
    fittings to comply with the proposed rule is expected to be from 348 to 
    696 hours (87 x 4-8 hours per year). These estimates include time for 
    reviewing instructions, searching existing data sources, gathering and 
    maintaining the data needed, and completing the collection of 
    information.
        The collections of information contained in this proposed rule are 
    considered the least burdensome for meeting the legal requirements and 
    achieving the program objectives of the DOE compliance certification 
    program for faucets, showerheads, water closets and urinals. In 
    estimating the paperwork and recordkeeping burden, DOE considered that 
    many manufacturers already submit this type of information to voluntary 
    plumbing product listing services, such as the International 
    Association of Plumbing & Mechanical Officials' (IAPMO's) Annual 
    Directory of Listed Plumbing Products. These manufacturers should be 
    able to comply with the certification required by the proposed rule 
    without much additional burden.
        DOE invites public comments concerning the accuracy of the 
    estimated paperwork reporting burden. Send comments regarding the 
    recordkeeping and reporting burden estimate, or any other aspect of 
    this collection of information, to the Department in accordance with 
    the instructions in the ADDRESSES section of today's notice, section 
    IV, and to the Office of Information and Regulatory Affairs, Office of 
    Management and Budget, Washington, DC 20503, marked ``Attention: Desk 
    Officer for DOE.''
    
    G. Review Under Executive Order 12988, ``Civil Justice Reform''
    
        With respect to the review of existing regulations and the 
    promulgation of new regulations, Section 3(a) of Executive Order 12988, 
    ``Civil Justice Reform,'' 61 FR 4729 (February 7, 1996), imposes on 
    executive agencies the general duty to adhere to the following 
    requirements: (1) eliminate drafting errors and ambiguity; (2) write 
    regulations to minimize litigation; and (3) provide a clear legal 
    standard for affected conduct rather than a general standard and 
    promote simplification and burden reduction. With regard to the review 
    required by Section 3(a), Section 3(b) of the Executive Order 
    specifically requires that Executive agencies make every reasonable 
    effort to ensure that the regulation: (1) clearly specifies the 
    preemptive effect, if any; (2) clearly specifies any effect on existing 
    Federal law or regulation; (3) provide a clear legal standard for 
    affected conduct while promoting simplification and burden reduction; 
    (4) specifies the retroactive effect, if any; (5) adequately defines 
    key terms; and (6) addresses other important issues affecting clarity 
    and general draftsmanship under any guidelines issued by the Attorney 
    General. Section 3(c) of the Executive Order requires Executive 
    agencies to review regulations in light of applicable standards Section 
    3(a) and Section 3(b) to determine whether they are met or it is 
    unreasonable to meet one or more of them. DOE reviewed today's proposed 
    rulemaking under the standards of Section 3 of the Executive Order and 
    determined that, to the extent permitted by law, they meet the 
    requirements of those standards.
    
    H. Review Under Section 32 of the Federal Energy Administration Act of 
    1974
    
        Pursuant to Section 301 of the Department of Energy Organization 
    Act (Pub. L. 95-91), the Department of Energy is required to comply 
    with Section 32 of the Federal Energy Authorization Act (FEAA), as 
    amended by Section 9 of the Federal Energy Administration Authorization 
    Act of 1977 (Pub. L. 95-70). Section 32 provides in essence that, where 
    a proposed rule contains or involves use of commercial standards, the 
    notice of proposed rulemaking must inform the public of the use and 
    background of such standards.
        The rule proposed in this notice adopts one commercial standard, 
    ASME/ANSI Standard A112.19.6-1990, and incorporates another, ASME/ANSI 
    A112.18.1M-1994. In regard to ASME/ANSI Standard A112.19.6-1990, the 
    Act directs adoption of this commercial standard, which provides the 
    procedures required for measuring the water consumption of water 
    closets and urinals. Because Congress has directed the use of the 
    standard, Section 32 of the FEAA has no application to it. In regard to 
    ASME/ANSI Standard A112.18.1M-1994, which provides the procedures 
    required for measuring the water consumption of faucets and 
    showerheads, the Department has evaluated this Standard and is unable 
    to conclude whether it was developed in a manner which fully provides 
    for public participation, comment, and review. However, Congress has, 
    by statute, mandated use of the ASME/ANSI Standard unless specific 
    findings are made.
        As required by Section 32(c) of the Federal Energy Administration 
    Act, the Department will consult with the Attorney General and the 
    Chairman of the Federal Trade Commission concerning the impact of this 
    standard on competition, prior to prescribing a final rule.
    
    I. Review Under Unfunded Mandates Reform Act of 1995
    
        Section 202 of the Unfunded Mandates Reform Act of 1995 (``Unfunded 
    Mandates Act'') requires that the Department prepare a budgetary impact 
    statement before promulgating a rule that includes a Federal mandate 
    that may result in expenditure by state, local, and tribal governments, 
    in the aggregate, or by the private sector, of $100 million or more in 
    any one year. The budgetary impact statement must include: (i) 
    identification of the Federal law under which the rule is promulgated; 
    (ii) a qualitative and quantitative assessment of anticipated costs and 
    benefits of the Federal mandate and an analysis of the extent to which 
    such costs to state, local, and tribal governments may be paid with 
    Federal financial assistance; (iii) if feasible, estimates of the 
    future compliance costs and of any
    
    [[Page 7845]]
    
    disproportionate budgetary effects the mandate has on particular 
    regions, communities, non-Federal units of government, or sectors of 
    the economy; (iv) if feasible, estimates of the effect on the national 
    economy; and (v) a description of the Department's prior consultation 
    with elected representatives of state, local, and tribal governments 
    and a summary and evaluation of the comments and concerns presented.
        The Department has determined that the action proposed today does 
    not include a Federal mandate that may result in estimated costs of 
    $100 million or more to state, local or to tribal governments in the 
    aggregate or to the private sector. Therefore, the requirements of 
    Sections 203 and 204 of the Unfunded Mandates Act do not apply to this 
    action.
    
    IV. Public Comment.
    
    A. Written Comment Procedures
    
        Interested persons are invited to participate in the proposed 
    rulemaking by submitting data, comments, or information with respect to 
    the proposed issues set forth in sections (II)(A)(1)(a), (II)(A)(2)(a), 
    (II)(B), and (II)(C) of this notice to the address indicated at the

    and adjacent to the fixture inlet so as to cause an effective 
    enlargement of the supply line immediately before the unit.
        Flushometer valve means a valve attached to a pressurized water 
    supply pipe and so designed that when actuated, it opens the line for 
    direct flow into the fixture at a rate and quantity to properly operate 
    the fixture, and then gradually closes to provide trap reseal in the 
    fixture in order to avoid water hammer. The pipe to which this device 
    is connected is in itself of sufficient size, that when open, will 
    allow the device to deliver water at a
    
    [[Page 7847]]
    
    sufficient rate of flow for flushing purposes.

    Subpart D--Petitions To Exempt State Regulation From Preemption; 
    Petitions To Withdraw Exemption of State Regulation
    
        12. Section 430.40 of subpart D is revised to read as follow:
    
    
    Sec. 430.40  Purpose and scope.
    
        (a) This subpart prescribes the procedures to be followed in 
    connection with petitions requesting a rule that a State regulation 
    prescribing an energy or water conservation standard or other 
    requirement respecting energy efficiency, energy use, or water use of a 
    type (or class) of covered product not be preempted.
        (b) This subpart also prescribes the procedures to be followed in 
    connection with petitions to withdraw a rule exempting a State 
    regulation prescribing an energy or water conservation standard or 
    other requirement respecting energy efficiency, energy use, or water 
    use of a type (or class) of covered product.
        13. Section 430.41 of subpart D is revised to read as follows:
    
    
    Sec. 430.41  Prescriptions of a rule.
    
        (a) Criteria for exemption from preemption. Upon petition by a 
    State which has prescribed an energy or water conservation standard or 
    other requirement for a type or class of covered equipment for which a 
    Federal energy or water conservation standard is applicable, the 
    Secretary shall prescribe a rule that such standard not be preempted if 
    he determines that the State has established by a preponderance of 
    evidence that such requirement is needed to meet unusual and compelling 
    State or local energy or water interests. For the purposes of this 
    section, the term ``unusual and compelling State or local energy or 
    water interests'' means interests which are substantially different in 
    nature or
    
    [[Page 7849]]
    
    magnitude than those prevailing in the U.S. generally, and are such 
    that when evaluated within the context of the State's energy or water 
    plan and forecast, the costs, benefits, burdens, and reliability of 
    energy or water savings resulting from the State regulation make such 
    regulation preferable or necessary when measured against the costs, 
    benefits, burdens, and reliability of alternative approaches to energy 
    or water savings or production, including reliance on reasonably 
    predictable market-induced improvements in efficiency of all equipment 
    subject to the State regulation. The Secretary may not prescribe such a 
    rule if he finds that interested persons have established, by a 
    preponderance of the evidence, that the State's regulation will 
    significantly burden manufacturing, marketing, distribution, sale or 
    servicing of the covered equipment on a national basis. In determining 
    whether to make such a finding, the Secretary shall evaluate all 
    relevant factors including: the extent to which the State regulation 
    will increase manufacturing or distribution costs of manufacturers, 
    distributors, and others; the extent to which the State regulation will 
    disadvantage smaller manufacturers, distributors, or dealers or lessen 
    competition in the sale of the covered product in the State; the extent 
    to which the State regulation would cause a burden to manufacturers to 
    redesign and produce the covered product type (or class), taking into 
    consideration the extent to which the regulation would result in a 
    reduction in the current models, or in the projected availability of 
    models, that could be shipped on the effective date of the regulation 
    to the State and within the U.S., or in the current or projected sales 
    volume of the covered product type (or class) in the State and the 
    U.S.; and the extent to which the State regulation is likely to 
    contribute significantly to a proliferation of State appliance 
    efficiency requirements and the cumulative impact such requirements 
    would have. The Secretary may not prescribe such a rule if he finds 
    that such a rule will result in the unavailability in the State of any 
    covered product (or class) of performance characteristics (including 
    reliability), features, sizes, capacities, and volumes that are 
    substantially the same as those generally available in the State at the 
    time of the Secretary's finding. The failure of some classes (or types) 
    to meet this criterion shall not affect the Secretary's determination 
    of whether to prescribe a rule for other classes (or types).
        (1) Requirements of petition for exemption from preemption. A 
    petition from a State for a rule for exemption from preemption shall 
    include the information listed in paragraphs (a)(1)(i) through 
    (a)(1)(vi) of this section. A petition for a rule and correspondence 
    relating to such petition shall be available for public review except 
    for confidential or proprietary information submitted in accordance 
    with the Department of Energy's Freedom of Information Regulations set 
    forth in 10 CFR Part 1004:
        (i) The name, address, and telephone number of the petitioner;
        (ii) A copy of the State standard for which a rule exempting such 
    standard is sought;
        (iii) A copy of the State's energy or water plan and forecast;
        (iv) Specification of each type or class of covered product for 
    which a rule exempting a standard is sought;
        (v) Other information, if any, believed to be pertinent by the 
    petitioner; and
        (vi) Such other information as the Secretary may require.
        (2) [Reserved]
        (b) Criteria for exemption from preemption when energy or water 
    emergency conditions exist within State. Upon petition by a State which 
    has prescribed an energy or water conservation standard or other 
    requirement for a type or class of covered product for which a Federal 
    energy or water conservation standard is applicable, the Secretary may 
    prescribe a rule, effective upon publication in the Federal Register, 
    that such State regulation not be preempted if he determines that in 
    addition to meeting the requirements of paragraph (a) of this section 
    the State has established that: an energy or water emergency condition 
    exists within the State that imperils the health, safety, and welfare 
    of its residents because of the inability of the State or utilities 
    within the State to provide adequate quantities of gas, electric 
    energy, or water to its residents at less than prohibitive costs; and 
    cannot be substantially alleviated by the importation of energy or 
    water or the use of interconnection agreements; and the State 
    regulation is necessary to alleviate substantially such condition.
        (1) Requirements of petition for exemption from preemption when 
    energy or water emergency conditions exist within a State. A petition 
    from a State for a rule for exemption from preemption when energy or 
    water emergency conditions exist within a State shall include the 
    information listed in paragraphs (a)(1)(i) through (a)(1)(vi) of this 
    section. A petition shall also include the information prescribed in 
    paragraphs (b)(1)(i) through (b)(1)(iv) of this section, and shall be 
    available for public review except for confidential or proprietary 
    information submitted in accordance with the Department of Energy's 
    Freedom of Information Regulations set forth in 10 CFR Part 1004:
        (i) A description of the energy or water emergency condition which 
    exists within the State, including causes and impacts.
        (ii) A description of emergency response actions taken by the State 
    and utilities within the State to alleviate the emergency condition;
        (iii) An analysis of why the emergency condition cannot be 
    alleviated substantially by importation of energy or water or the use 
    of interconnection agreements; and
        (iv) An analysis of how the State standard can alleviate 
    substantially such emergency condition.
        (2) [Reserved]
        (c) Criteria for withdrawal of a rule exempting a State standard. 
    Any person subject to a State standard which, by rule, has been 
    exempted from Federal preemption and which prescribes an energy or 
    water conservation standard or other requirement for a type or class of 
    a covered product, when the Federal energy or water conservation 
    standard for such product subsequently is amended, may petition the 
    Secretary requesting that the exemption rule be withdrawn. The 
    Secretary shall consider such petition in accordance with the 
    requirements of paragraph (a) of this section, except that the burden 
    shall be on the petitioner to demonstrate that the exemption rule 
    received by the State should be withdrawn as a result of the amendment 
    to the Federal standard. The Secretary shall withdraw such rule if he 
    determines that the petitioner has shown the rule should be withdrawn.
        (1) Requirements of petition to withdraw a rule exempting a State 
    standard. A petition for a rule to withdraw a rule exempting a State 
    standard shall include the information prescribed in paragraphs 
    (c)(1)(i) through (c)(1)(vii) of this section, and shall be available 
    for public review, except for confidential or proprietary information 
    submitted in accordance with the Department of Energy's Freedom of 
    Information Regulations set forth in 10 CFR Part 1004:
        (i) The name, address and telephone number of the petitioner;
        (ii) A statement of the interest of the petitioner for which a rule 
    withdrawing an exemption is sought;
        (iii) A copy of the State standard for which a rule withdrawing an 
    exemption is sought;
    
    [[Page 7850]]
    
        (iv) Specification of each type or class of covered product for 
    which a rule withdrawing an exemption is sought;
        (v) A discussion of the factors contained in paragraph (a) of this 
    section;
        (vi) Such other information, if any, believed to be pertinent by 
    the petitioner; and
        (vii) Such other information as the Secretary may require.

        17. Section 430.60 of subpart F is revised to read as follows:
    
    
    Sec. 430.60  Purpose and scope.
    
        This subpart sets 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 or water 
    conservation standard set forth in Subpart C of this part. Energy and 
    water conservation standards include minimum levels of efficiency and 
    maximum levels of consumption (also referred to as performance 
    standards), and prescriptive energy design requirements (also referred 
    to as design standards).

    Building, 1000 Independence Avenue, SW, Washington, DC 20585-0121 
    within six months of being discontinued. For each basic model, this 
    report shall include: product type, product class, the manufacturer's 
    name, the private labeler name(s), if applicable, and the 
    manufacturer's model number. If the reporting of discontinued models 
    coincides with the submittal of a certification report, such models can 
    be included in the certification report.
        (d) Maintenance of records. The manufacturer of any covered product 
    subject to any of the energy and water performance standards or 
    procedures prescribed in this part shall establish, maintain, and 
    retain the records of the underlying test data for all certification 
    testing. Such records shall be organized and indexed in a fashion which 
    makes them readily accessible for review by DOE upon request. The 
    records shall include the supporting test data associated with tests 
    performed on any test units to satisfy the requirements of this 
    subpart. The records shall be retained by the manufacturer for a period 
    of two years from the date that production of the applicable model has 
    ceased.
        (e) Third party representation. A manufacturer may elect to use a 
    third party to submit the certification report to DOE (for example a 
    trade association or other authorized representative). Such 
    certification reports shall include all the information specified in 
    paragraph (a)(4) of this section. The certification report must be 
    submitted with a compliance statement as specified in paragraph (a)(3) 
    of this section. A third party representative may also submit 
    discontinued model information on behalf of an authorizing 
    manufacturer.
        (f) Amendment of information. If any compliance certification 
    information on a statement or report previously submitted to DOE has 
    changed, the manufacturer or his representative must submit the revised 
    information, by certified mail, to: Department of Energy, Office of 
    Energy Efficiency and Renewable Energy, Office of Codes and Standards, 
    Forrestal Building, 1000 Independence Avenue, SW, Washington, DC 20585-

    be based on the testing conducted in accordance with the statistical 
    sampling procedures set forth in appendix B of this subpart and the 
    test procedures set forth in Subpart B of this part.
    * * * * *
        (6) Testing at manufacturer's option. (i) If a manufacturer's basic 
    model is determined to be in noncompliance with the applicable energy 
    or water performance standard at the conclusion of DOE testing in 
    accordance with the double sampling plan specified in appendix B of 
    this subpart, the manufacturer may request that DOE conduct additional 
    testing of the model according to procedures set forth in appendix B of 
    this subpart.
    * * * * *

    Appendix B to Subpart F of Part 430--Sampling Plan for Enoforcement 
    Testing
    
    I. Double Sampling
    
        Step 1. The first sample size (n1) must be four or more 
    units.
        Step 2. Compute the mean (x1) of the measured energy or 
    water performance of the n1 units in the first sample as 
    follows:
    [GRAPHIC] [TIFF OMITTED] TP20FE97.000
    
    Where (xi) is the measured energy efficiency, energy or water 
    consumption of unit i.
    
        Step 3. Compute the standard deviation (s1) of the measured 
    energy or water performance of the (n1) units in the first 
    sample as follows:
    [GRAPHIC] [TIFF OMITTED] TP20FE97.001
    
    [GRAPHIC] [TIFF OMITTED] TP20FE97.002
    
    [GRAPHIC] [TIFF OMITTED] TP20FE97.003
    
        Step 5. Compute the upper control limit (UCL1) and lower 
    control limit (LCL1) for the mean of the first sample using the 
    applicable DOE energy or water performance standard (EPS) as the 
    desired mean and a probability level of 95 percent (two-tailed test) 
    as follows:
    [GRAPHIC] [TIFF OMITTED] TP20FE97.004
    
    Where t is a statistic based on a 95 percent two-tailed probability 
    level and a sample size of n1.
    
        Step 6a. For an Energy Efficiency Standard, compare the mean of 
    the first sample (x1) with the upper and lower control limits 
    (UCL1 and LCL1) to determine one of the following:
        (1) If the mean of the first sample is below the lower control 
    limit, then the basic model is in noncompliance and testing is at an 
    end. (Do not go on to any of the steps below.)
        (2) If the mean of the first sample is equal to or greater than 
    the upper control limit, then the basic model is in compliance and 
    testing is at an end. (Do not go on to any of the steps below.)
        (3) If the sample mean is equal to or greater than the lower 
    control limit but less than the upper control limit, then no 
    determination of compliance or noncompliance can be made and a 
    second sample size is determined by Step 7(a).
        Step 6b. For an Energy or Water Consumption Standard, compare 
    the mean of the first sample (x1) with the upper and lower 
    control limits (UCL1 and LCL1) to determine one of the 
    following:
        (1) If the mean of the first sample is above the upper control 
    limit, then the basic model is in noncompliance and testing is at an 
    end. (Do not go on to any of the steps below.)
        (2) If the mean of the first sample is equal to or less than the 
    lower control limit, then the basic model is in compliance and 
    testing is at an end. (Do not go on to any of the steps below.)
        (3) If the sample mean is equal to or less than the upper 
    control limit but greater than the lower control limit, then no 
    determination of compliance or noncompliance can be made and a 
    second sample size is determined by Step 7(b).
        Step 7a. For an Energy Efficiency Standard, determine the second 
    sample size (n2) as follows:
    [GRAPHIC] [TIFF OMITTED] TP20FE97.005
    
    Where s1 and t have the values used in Steps 4 and 5, 
    respectively. The term ``0.05 EPS'' is the difference between the 
    applicable energy efficiency standard and 95 percent of the 
    standard, where 95 percent of the standard is taken as the lower 
    control limit. This procedure yields a sufficient combined sample 
    size (n1+n2) to give an estimated 97.5 percent probability 
    of obtaining a determination of compliance when the true mean 
    efficiency is equal to the applicable standard. Given the solution 
    value of n2, determine one of the following:
        (1) If the value of n2 is less than or equal to zero and if 
    the mean energy efficiency of the first sample (x1) is either 
    equal to or greater than the lower control limit (LCL1) or 
    equal to or greater than 95 percent of the applicable energy 
    efficiency standard (EES), whichever is greater, i.e., if n2 
    0 and (x1) max (LCL1, 0.95 EES), the 
    basic model is in compliance and testing is at an end.
        (2) If the value of n2 is less than or equal to zero and 
    the mean energy efficiency of the first sample (x1) is less 
    than the lower control limit (LCL1) or less than 95 percent of 
    the applicable energy efficiency standard (EES), whichever is 
    greater, i.e., if n2  0 and (x1) < max="">1, 0.95 EES), the basic model is in noncompliance and 
    testing is at an end.
        (3) If the value of n2 is greater than zero, then value of 
    the second sample size is determined to be the smallest integer 
    equal to or greater than the solution value of n2 for equation 
    (6a). If the value of n2 so calculated is greater than 20-
    n1, set n2 equal to 20-n.
    
        Step 7(b). For an Energy or Water Consumption Standard, 
    determine the second sample size (n2) as follows:
    [GRAPHIC] [TIFF OMITTED] TP20FE97.006
    
    Where s1 and t have the values used in Steps 4 and 5, 
    respectively. The term ``0.05 EPS'' is the difference between the 
    applicable energy or water consumption standard and 105 percent of 
    the standard, where 105 percent of the standard is taken as the 
    upper control limit. This procedure yields a sufficient combined 
    sample size (n1 + n2) to give an estimated 97.5 percent 
    probability of obtaining a determination of compliance when the true 
    mean consumption is equal to the applicable standard.
        Given the solution value of n2, determine one of the 
    following:
        (1) If the value of n2 is less than or equal to zero and if 
    the mean energy or water consumption of the first sample (x1) 
    is either equal to or less than the upper control limit (UCL1) 
    or equal to or less than 105 percent of the applicable energy or 
    water performance standard (EPS), whichever is less, i.e., if 
    n2  0 and (x1) min (UCL1, 1.05 
    EPS), the basic model is in compliance and testing is at an end.
        (2) If the value of n2 is less than or equal to zero and 
    the mean energy or water consumption of the first sample (x1) 
    is greater than the upper control limit (UCL1) or more than 105 
    percent of the applicable energy or water performance standard 
    (EPS),
    
    [[Page 7853]]
    
    whichever is less, i.e., if n2  0 and x1 > min 
    (LCL1, 1.05 EPS), the basic model is in noncompliance and 
    testing is at an end.
        (3) If the value of n2 is greater than zero, then the value 
    of the second sample size is determined to be the smallest integer 
    equal to or greater than the solution value of n2 for equation 
    (6b). If the value of n2 so calculated is greater than 20-
    n1, set n2 equal to 20-n1.
        Step 8. Compute the combined mean (x2) of the measured 
    energy or water performance of the n1 and n2 units of the 
    combined first and second samples as follows:
    [GRAPHIC] [TIFF OMITTED] TP20FE97.007
    
    [GRAPHIC] [TIFF OMITTED] TP20FE97.008
    
    [GRAPHIC] [TIFF OMITTED] TP20FE97.009
    
        Where s1 is the value obtained in Step 3.
        Step 10(a). For an Energy Efficiency Standard, compute the lower 
    control limit (LCL2) for the mean of the combined first and 
    second samples using the DOE energy efficiency standard (EES) as the 
    desired mean and a one-tailed probability level of 97.5 percent 
    (equivalent to the two-tailed probability level of 95 percent used 
    in Step 5) as follows:
    [GRAPHIC] [TIFF OMITTED] TP20FE97.010
    
    Where the t-statistic has the value obtained in step 5.
    
        Step 10(b). For an Energy or Water Consumption Standard, compute 
    the upper control limit (UCL2) for the mean of the combined 
    first and second samples using the DOE energy or water performance 
    standard (EPS) as the desired mean and a one-tailed probability 
    level of 102.5 percent (equivalent to the two-tailed probability 
    level of 95 percent used in Step 5) as follows:
    [GRAPHIC] [TIFF OMITTED] TP20FE97.011
    
    Where the t-statistic has the value obtained in Step 5.
    
        Step 11(a). For an Energy Efficiency Standard, compare the 
    combined sample mean (x2) to the lower control limit 
    (LCL2) to find one of the following:
        (1) If the mean of the combined sample (x2) is less than 
    the lower control limit (LCL2) or 95 percent of the applicable 
    energy efficiency standard (EES), whichever is greater, i.e., if 
    (x2) < max="">2, 0.95 EES), the basic model is in 
    noncompliance and testing is at an end.
        (2) If the mean of the combined sample (x2) is equal to or 
    greater than the lower control limit (LCL2) or 95 percent of 
    the applicable energy efficiency standard (EES), whichever is 
    greater, i.e., if (x2)  max (LCL2, 0.95 EES), 
    the basic model is in compliance and testing is at an end.
        Step 11(b). For an Energy or Water Consumption Standard, compare 
    the combined sample mean (x2) to the upper control limit 
    (UCL2) to find one of the following:
        (1) If the mean of the combined sample (x2) is greater than 
    the upper control limit (UCL2) or 105 percent of the applicable 
    energy or water performance standard (EPS), whichever is less, i.e., 
    if x2 > min (UCL2, 1.05 EPS), the basic model is in 
    noncompliance and testing is at an end.
        (2) If the mean of the combined sample (x2) is equal to or 
    less than the upper control limit (UCL2) or 105 percent of the 
    applicable energy or water performance standard (EPS), whichever is 
    less, i.e., if (x2)  min (UCL2, 1.05 EPS), the 
    basic model is in compliance and testing is at an end.
    
    II. Manufacturer-Option Testing
    
        If a determination of non-compliance is made in Steps 6, 7 or 
    11, the manufacturer may request that additional testing be 
    conducted, in accordance with the following procedures.
        Step A. The manufacturer requests that an additional number, 
    n3, of units be tested, with n3 chosen such that 
    n1+n2+n3 does not exceed 20.
        Step B. Compute the mean energy or water performance, standard 
    error, and lower or upper control limit of the new combined sample 
    in accordance with the procedures prescribed in Steps 8, 9, and 10, 
    above.
        Step C. Compare the mean performance of the new combined sample 
    to the revised lower or upper control limit to determine one of the 
    following:
        a.1. For an Energy Efficiency Standard, if the new combined 
    sample mean is equal to or greater than the lower control limit or 
    95 percent of the applicable energy efficiency standard, whichever 
    is greater, the basic model is in compliance and testing is at an 
    end.
        a.2. For an Energy or Water Consumption Standard, if the new 
    combined sample mean is equal to or less than the upper control 
    limit or 105 percent of the applicable energy or water consumption 
    standard, whichever is less, the basic model is in compliance and 
    testing is at an end.
        b.1. For an Energy Efficiency Standard, if the new combined 
    sample mean is less than the lower control limit or 95 percent of 
    the applicable energy efficiency standard, whichever, is greater, 
    and the value of n1+n2+n3 is less than 20, the 
    manufacturer may request that additional units be tested. The total 
    of all units tested may not exceed 20. Steps A, B, and C are then 
    repeated.
        b.2. For an Energy or Water Consumption Standard, if the new 
    combined sample mean is greater than the upper control limit or 105 
    percent of the applicable energy or water consumption standard, 
    whichever is less, and the value of n1+n2+n3 is less 
    than 20, the manufacturer may request that additional units be 
    tested. The total of all units tested may not exceed 20. Steps A, B, 
    and C are then repeated.
        c. Otherwise, the basic model is determined to be in 
    noncompliance.
