DOE has tentatively determined that the proposed amendments described in section III of this NOPR would not alter the measured water use of water closets and urinals, which is representative of average use cycles, and that the proposed test procedures would not be unduly burdensome to conduct.
Discussion of DOEs proposed actions are addressed in detail in section III of this NOPR.
III. Discussion A. Scope of Applicability This NOPR applies to both water closets and urinals, as defined in 10
CFR 430.2. DOE defines a water closet as a plumbing fixture that has a watercontaining receptor that receives liquid and solid body waste, and upon actuation, conveys the waste through an exposed integral trap seal into a gravity drainage system, except such term does not include fixtures designed for installation in prisons. 10 CFR 430.2.
DOE defines a urinal as a plumbing fixture that receives only liquid body waste and, on demand, conveys the waste through a trap seal into a gravity drainage system, except such term does not include fixtures designed for installations in prisons. Id.
The proposed updates in this NOPR
would not change the scope of the test procedures for water closets or urinals.
B. Updates to Industry Standards Currently, DOEs test procedures for water closets and urinals in Appendix T
incorporate by reference ASME
A112.19.22008,6 sections 7.1, 7.1.1, 7.1.2, 7.1.3, 7.1.4, 7.1.5, 7.4, 8.2, 8.2.1, 8.2.2, 8.2.3, 8.6, Table 5, and Table 6.
These sections and tables provide procedures for testing and measuring water consumption, specifications for test apparatus, and other general requirements for the testing of water closets and urinals.
ASME A112.19.22018, the current version of the standard, amends pertinent sections of the 2008 version 6 This reference includes Update No. 1, dated August 2009, and Update No. 2, dated March 2011.

currently incorporated into 10 CFR part 430. These amendments include 1
editorial changes and clarification in sections 7.1.2, 7.3.2,7 8.6.4, and Figure 12; 8 2 a correction in section 8.2.1 to the water consumption static test pressure value for urinals to reflect the corresponding value in Table 6; and 3
additions to Table 5 that do not appear to be relevant to the water consumption test for water closets. In the August 2019
RFI, DOE had tentatively determined that these amendments would not impact 1 the measured values of water use for water closets and urinals under Appendix T, 2 the representativeness of the results, or 3 the test burden, and requested comment on this tentative determination. 84 FR 37970, 37973.
In response to the August 2019 RFI, PMI generally agreed with DOEs evaluation of ASME A112.19.22018, as compared to the currently referenced version. PMI, No. 3 at p. 1 9 The CA
IOUs generally supported updating the referenced ASME A112.19.2 standard to the 2013 version, which they stated is the most recent version formally approved and accepted, to capture substantive updates. CA IOUs, No. 4 at p. 2. The CA IOUs also recommended that DOE include less substantive updates from the 2018 edition, including definitions, editorial changes, and corrections. Id. Specifically, the CA
IOUs suggested that DOE make the correction in section 8.2.1 of ASME
A112.19.22018 to the water consumption static pressure value for urinals in DOEs regulations to reflect the corresponding value in Table 6. CA
IOUs, No. 4 at p. 4 Other stakeholders 7 The water consumption test is section 7.4 in ASME A112.19.22008, but section 7.3 in ASME
A112.19.22018.
8 While Figure 12 is not incorporated by reference in 10 CFR 430.3h2, Figure 12 is referenced within section 7.1.1, which is currently incorporated by reference.

did not comment directly on DOEs evaluation of the 2013 and 2018
versions of ASME A112.19.2.
DOE reiterates its tentative determination from the August 2019 RFI
that the amendments in ASME
A112.19.22018 would not impact 1
the measured values of water use for water closets and urinals under Appendix T, 2 the representativeness of the results, or 3 the test burden. As stated previously, ASME A112.19.2
2018 is the most recent version of the industry standard, and DOE
understands the 2018 version to have been approved by ANSI on June 15, 2018.10 The CA IOUs stated that the 2013 version of ASME A112.19.2
contains substantive updates to the 2008
version, currently referenced in DOEs test procedures. If DOE adopts the 2018
version as proposed, DOEs regulations would reflect the substantive updates of interest to the CA IOUs. For the reasons described in the August 2019 RFI and reiterated previously, DOE is proposing to incorporate by reference ASME
A112.19.22018.
DOE requests comment on its proposal to incorporate by reference ASME A112.19.22018.
DOE also proposes to remove references in Appendix T to the industry standard that are superfluous.
Specifically, Appendix T references section 7.1 in addition to subsections 7.1.1, 7.1.2, 7.1.3, 7.1.4 and 7.1.5 of ASME A112.19.22008.11 Section 7.1
only provides the title General, without any other content. The referenced subsections 7.1.1, 7.1.2, 7.1.3, 7.1.4 and 7.1.5 provide the general specifications needed for performing the test procedure. Therefore, DOE proposes to exclude the reference to section 7.1
of ASME A112.19.22018 in Appendix T. Similarly, section 8.2 only provides the title Test apparatus and general 10 ANSI approval of A112.19.22018 indicated in ASME A112 Standards Status Report, available at https cstools.asme.org/csconnect/Filedownload.
