Title 40

SECTION 92.12

92.12 Interim provisions.

§ 92.12 Interim provisions.

Notwithstanding other provisions of this part, the following provisions apply as specified to locomotives and locomotive engines subject to the provisions of this part:

(a) Tier 0 standards. In addition to the requirements of § 92.8(a)(1)(i), the following new locomotives and new locomotive engines are subject to the Tier 0 emission standards of § 92.8. The requirements of this paragraph do not apply to passenger locomotives. The requirements of this paragraph (a) provide manufacturers of freshly manufactured locomotives two options for compliance. The first option is to comply with the requirements of paragraphs (a) (1) and (2) of this section, which has the effect of requiring compliance with Tier 0 standards on average beginning on January 1, 2001 for all freshly manufactured and remanufactured locomotives originally manufactured on or after January 1, 1994. The second option requires compliance with the requirements of paragraph (a)(3) of this section that the manufacturer make a remanufacturing system available at a reasonable cost for its primary model for the 1994 through 1997 production period prior to January 1, 2000, and to apply the same emission controls to its new production of similar locomotives. Manufacturers complying with paragraph (a)(3) of this section would be allowed to manufacture and remanufacture other locomotives without a certificate of conformity, prior to January 1, 2002, except as required by paragraph (a)(2)(ii) of this section. Manufacturers may comply with paragraph (a)(3) of this section through compliance with the provisions of paragraph (a)(5) of this section.

(1) Freshly manufactured locomotives. Except as provided in paragraph (a)(3) of this section, all freshly manufactured locomotives manufactured on or after January 1, 2001 must comply with the emission standards listed in Table A8-1 of § 92.8 and all other applicable requirements of this part.

(2) Remanufactured locomotives. The following locomotives (and engines used in the following locomotives) must comply with the emission standards listed in Table A8-1 of § 92.8 and all other applicable requirements of this part:

(i) Locomotives originally manufactured on or after January 1, 1994, that are remanufactured on or after January 1, 2001; and

(ii) Locomotives originally manufactured on or after January 1, 1990 for which a remanufacturing system has been certified to Tier 0 standards and is available for use at reasonable cost.

(3) New model exemption. (i) Freshly manufactured locomotive models not introduced for widespread production prior to January 1, 1998 are exempt from the requirements of paragraph (a)(1) of this section provided the manufacturer of the locomotive:

(A) Has obtained a certificate of conformity and made available for use at reasonable cost before January 1, 2000, a remanufacturing system for its primary locomotive model (including its primary engine model) originally manufactured between January 1, 1994 and January 1, 1998; and

(B) Complies with the emission standards listed in Table A8-1 of § 92.8 and all applicable requirements of this part for all freshly manufactured locomotives manufactured on or after January 1, 2000 that are similar to the primary model described in paragraph (a)(3)(i)(A) of this section.

(ii) New locomotives and locomotive engines that are manufactured and remanufactured by a manufacturer that complies with the requirements of paragraphs (a)(3)(i) (A) and (B) of this section, and that are not similar to the locomotive models identified in paragraphs (a)(3)(i) (A) and (B) of this section are exempt from the requirements of paragraphs (a)(1) and (a)(2)(i) of this section.

(4) Make available at a reasonable cost means to make a certified remanufacturing system available for use where:

(i) The total cost to the owner and user of the locomotive (including initial hardware, increased fuel consumption, and increased maintenance costs) during the useful life of the locomotive is less than $220,000; and

(ii) The initial hardware costs are reasonably related to the technology included in the remanufacturing system and are less than $50,000 for 2-stroke locomotives and 4-stroke locomotives equipped with split cooling systems, or $125,000 for 4-stroke locomotives not equipped with split cooling systems; and

(iii) The system will not increase fuel consumption by more than 3 percent; and

(iv) The remanufactured locomotive will have reliability throughout its useful life that is similar to the reliability the locomotive would have had if it had been remanufactured without the certified remanufacture system.

(5)(i) Instead of the provisions of paragraph (a)(3) of this section, a manufacturer may comply with the emissions standards listed in Table A8-1 of § 92.8 and all other applicable requirements of this part with respect to any combination of locomotive models that are manufactured or remanufactured on or after January 1, 2000, provided that the manufacturer has demonstrated to the satisfaction of the Administrator that such locomotives will produce greater emissions reductions than would otherwise occur through compliance with paragraph (a)(3) of this section.

(ii) New locomotives and locomotive engines that are manufactured and remanufactured by a manufacturer that complies with the requirements of paragraph (a)(5)(i) of this section, and that are not similar to the locomotive models identified in paragraph (a)(5)(i) of this section, are exempt from the requirements of paragraphs (a)(1) and (a)(2)(i) of this section.

(b) Production line and in-use testing. (1) The requirements of Subpart F of this part (i.e., production line testing) do not apply prior to January 1, 2002.

(2) The testing requirements of subpart F of this part (i.e., production line testing) do not apply to small manufacturers/remanufacturers prior to January 1, 2013. Note that the production line audit requirements apply as specified.

(3) The requirements of Subpart G of this part (i.e., in-use testing) only apply for locomotives and locomotive engines that become new on or after January 1, 2002.

(4) For locomotives and locomotive engines that are covered by a small business certificate of conformity, the requirements of Subpart G of this part (i.e., in-use testing) only apply for locomotives and locomotive engines that become new on or after January 1, 2007. We will also not require small remanufacturers to perform any in-use testing prior to January 1, 2013.

(c) Small business certificates of conformity. (1) Prior to January 1, 2007, small remanufacturers (as defined in § 92.2) may use a modified version of the federal test procedures of subpart B of this part to obtain certificates of conformity. Such certificates are valid only for production that occurs prior to January 1, 2007. Specifically, the following modifications are allowed:

(i) Measurement of HC, CO, and PM may be omitted;

(ii) Dynamometers are not required to meet the specifications of subpart B of this part, provided their design and use is consistent with good engineering practice;

(iii) Other modifications that are necessary because of excessive costs or technical infeasibility may be approved by the Administrator prior to the start of testing.

(2)(i) Small remanufacturers may use test procedures other than those specified in subpart B of this part or in paragraph (c)(1) of this section to obtain certificates of conformity, provided that the test procedures are consistent with good engineering practice, and are approved by the Administrator prior to the start of testing. Such certificates are valid only for production that occurs prior to January 1, 2007.

(ii) The total number of locomotives and locomotive engines that may be remanufactured under a certificate of conformity issued based on the testing described in paragraph (c)(2)(i) of this section shall be subject to the following annual limits for each individual remanufacturer: No more than 300 units in 2003, no more than 200 units in 2004, no more than 100 units in 2005, no more than 50 units in 2006. These sales limits apply to the combined number of locomotives and locomotive engines remanufactured within the calendar year that are covered by an individual remanufacturer's certificates issued under paragraph (c)(2)(i) of this section.

(3) Upon request, and prior to January 1, 2007, the Administrator may modify other certification requirements, as appropriate, for small remanufacturers.

(4) Remanufacturers certifying under this paragraph (c) shall provide along with their application for certification a brief engineering analysis describing the emission control technology to be incorporated in the remanufactured locomotive or locomotive engine, and demonstrating that such controls will result in compliance with the applicable standards.

(d) Early banking of emission credits. (1) Consistent with the provisions of subpart D of this part, NOx and PM emission credits may be generated from Tier 0 locomotives and locomotive engines prior to the applicable effective compliance date of the Tier 0 standard (i.e., the effective compliance date in § 92.8(a)(1)(i) or the effective compliance dates of paragraph (a) of this section, as applicable), relative to baseline emission rates.

(2)(i) Credits generated under this paragraph (d) that are granted or transferred to the owner or primary operator of the locomotives or locomotive engines generating credits may be used without restriction.

(ii) Credits generated under this paragraph (d) that are not granted or transferred to the owner or primary operator of the locomotives or locomotive engines generating credits may not be used for compliance with the Tier 0 standards for 2002 or later model years.

(3)(i) Prior to January 1, 2000, the provisions of this paragraph (d) apply to all locomotives and locomotive engines.

(ii) During the period January 1, 2000 through December 31, 2001, the provisions of this paragraph (d) apply only to engine families that include only locomotives and/or locomotive engines originally manufactured prior to January 1, 1990.

(iii) The provisions of this paragraph (d) other than the provisions of paragraph (d)(2) of this section do not apply to any locomotives and locomotive engines manufactured or remanufactured on or after January 1, 2002.

(4)(i) NOX credits generated under this paragraph (d) shall be calculated as specified in § 92.305, except that the applicable standard shall be replaced by:

(A) 10.5 g/bhp-hr for the line-haul cycle standards, and 14.0 g/bhp-hr for the switch standards; or

(B) For remanufactured locomotives, a measured baseline emission rate for the configuration with the lowest NOX emission rate in the applicable engine family that is approved in advance by the Administrator.

(ii) PM credits generated under this paragraph (d) shall be calculated as specified in § 92.305, except that the applicable standard shall be replaced by:

(A) 0.20 g/bhp-hr for the line-haul cycle standards, and 0.24 g/bhp-hr for the switch standards; or

(iii) The proration factor for all credits generated under this paragraph (d) shall be 0.143.

(5) Locomotives and locomotive engines generating credits under this paragraph (d) must meet all applicable requirements of this part.

(e) Particulate notch standards. For model year 2006 and earlier locomotives, the particulate notch standard shall be calculated as:

Notch standard = (EX) × (1.2 + (1−ELHx/std)).

(f) Passenger locomotives. Passenger locomotives originally manufactured before January 1, 2002 are exempt from the requirements and prohibitions of this part for model years through 2006. New passenger locomotives and locomotive engines produced on or after January 1, 2007 shall comply with all applicable requirements of this part.

(g) Tier 0 locomotive labels. Remanufacturers may use identical labels for locomotives and engines for Tier 0 locomotives, provided the remanufacturer demonstrates to EPA that they will supply two labels (one for the locomotive and one for the engine) only with those remanufacturing systems being applied to locomotives that have not been previously labeled (i.e., locomotives that have not been previously certified). For other locomotives, the remanufacturer may only supply one label.

(h) Labels for calendar year 2005. During calendar year 2005, manufacturers and remanufacturers may comply with the labeling requirements that were applicable during calendar year 2004, instead of the labeling requirements specified in § 92.212(c)(2)(v).

(i) Diesel test fuels. Manufacturers and remanufacturers may use LSD or ULSD test fuel to certify to the standards of this part, instead of the otherwise specified test fuel, provided PM emissions are corrected as described in this paragraph (i). Measure your PM emissions and determine your cycle-weighted emission rates as specified in subpart B of this part. If you test using LSD, add 0.04 g/bhp-hr to these weighted emission rates to determine your official emission result. If you test using ULSD, add 0.05 g/bhp-hr to these weighted emission rates to determine your official emission result.

(j) Subchapter U provisions. For model years 2008 through 2012, certain locomotives will be subject to the requirements of this part 92 while others will be subject to the requirements of 40 CFR subchapter U. This paragraph (j) describes allowances for manufacturers or remanufacturers to ask for flexibility in transitioning to the new regulations.

(1) You may ask to use a combination of the test procedures of this part and those of 40 CFR part 1033. We will approve your request if you show us that it does not affect your ability to show compliance with the applicable emission standards. Generally this requires that the combined procedures would result in emission measurements at least as high as those that would be measured using the procedures specified in this part. Alternatively, you may demonstrate that the combined effects of the procedures is small relative to your compliance margin (the degree to which your locomotives are below the applicable standards).

(2) You may ask to comply with the administrative requirements of 40 CFR part 1033 and 1068 instead of the equivalent requirements of this part.
