 AGENCY: Environmental Protection Agency.
 ACTION: Direct final rule.
 SUMMARY: The Environmental Protection Agency (EPA) is taking direct final action on several amendments involving technical clarifications for different mobile source regulations. First, we are making a variety of corrections to the Tier 3 motor vehicle emission and fuel standards. These changes generally correct or clarify various provisions from the Tier 3 rule without expanding the Tier 3 program or otherwise making substantive changes. Second, we are revising the test procedures and compliance provisions for nonroad spark-ignition engines at or below 19 kW (and for the corresponding nonroad equipment) to conform to current practices. The changes to evaporative emission test procedures also apply to some degree to other types of nonroad equipment powered by volatile liquid fuels. Third, we are addressing an ambiguity regarding permissible design approaches for portable fuel containers meeting evaporative emission standards. Fourth, we are revising the regulations to more carefully align with current requirements that apply to marine vessels with diesel engines as specified under MARPOL Annex VI. Fifth, we are correcting typographical errors in regulatory changes finalized in the Voluntary Quality Assurance Program rulemaking. This rulemaking action is not expected to result in any significant changes in regulatory burdens or costs.
 DATES: This final rule is effective on May 5, 2015, without further notice, unless EPA receives adverse comment by April 6, 2015. If EPA receives adverse comment on any provisions of the rule, we will publish a timely withdrawal in the 
                            **Federal Register**
                             informing the public that those specific provisions will not take effect. The incorporation by reference of certain publications listed in this regulation is approved by the Director of the Federal Register as of May 5, 2015.

SUPPLEMENTARY INFORMATION:  Why is EPA using a Direct Final Rule? EPA is publishing this rule without a prior proposed rule because we view this as a noncontroversial action and anticipate no adverse comment. This is also intended to expedite the regulatory process to allow the modifications to take effect as soon as possible. However, in the “Proposed Rules” section of today's 
                        **Federal Register**
                        , we are publishing a separate document that will serve as the proposed rule to adopt these same amendments if adverse comments are received on this direct final rule. We will not institute a second comment period on this action. Any parties interested in commenting must do so at this time. For further information about commenting on this rule, see the 
                        **ADDRESSES**
                         section of this document. If EPA receives adverse comment on a distinct provision of this rulemaking, we will publish a timely withdrawal in the 
                        **Federal Register**
                         indicating which provisions we are withdrawing. The provisions that are not withdrawn will become effective on the date set out above, notwithstanding adverse comment on any other provision. We would address all public comments in any subsequent final rule based on the proposed rule. EPA is publishing this direct final rule to expedite corrections to the regulatory text and clarifications and adjustments that generally reduce the burden and/or confusion related to 
                        ( print page 9079)
                        compliance with regulatory requirements. If you comment on this rule, we request that you identify any portions of the action with which you agree and support as written, in addition to any comments regarding suggestions for improvement or provisions with which you disagree. In the case of a comment that is otherwise not clearly adverse, EPA would interpret relevant comments calling for more flexibility or less restrictions as supportive of the direct final action. In this way, EPA will be able to adopt those elements of this action that are supported and most needed without delay, while considering and addressing any constructive or adverse comments received on the proposed rule in the course of developing the final rule. Does this action apply to me? Entities potentially affected by this rule include gasoline refiners and importers, ethanol producers, ethanol denaturant producers, butane and pentane producers, gasoline additive manufacturers, transmix processors, terminals and fuel distributors, light-duty vehicle manufacturers, manufacturers of nonroad engines and equipment, manufacturers of marine compression-ignition engines, and owners and operators of ocean-going vessels and other commercial ships, and manufacturers of portable fuel containers.

Portable Fuel Containers VII. MARPOL Annex VI Implementation VIII. Statutory and Executive Order Reviews IX. Statutory Provisions and Legal Authority I. Introduction In this action we are adopting several amendments that will make technical clarifications to different mobile source regulations. This section provides an overview of the organization of this preamble. Section II describes amendments to the Tier 3 motor vehicle emission standards. Section III describes amendments to the 40 CFR part 80 fuel standards: including the Tier 3 gasoline sulfur standards, other part 80 fuels regulations that were amended in the Tier 3 final rule, and amendments made in the Quality Assurance Program rulemaking. Section IV describes the changes to the testing and compliance provisions for nonroad spark-ignition engines, and Section V describes how we are changing the evaporative test procedures for nonroad equipment. Section VI describes amendments to the requirements that apply for portable fuel containers. Section VII summarizes the amendments related to our implementation of requirements for marine diesel engines and vessels under MARPOL Annex VI. II. Tier 3 Motor Vehicle Emission Standards On April 28, 2014, we published a final rule adopting new emission standards and fuel requirements for motor vehicles and for motor vehicle fuels (79 FR 23414). The final rule included Tier 3 emission standards to reduce exhaust and evaporative emissions from light-duty vehicles, light-duty trucks, and heavy-duty vehicles up to 14,000 pounds GVWR. In addition, the final rule specified corresponding changes to in-use fuel requirements. The Tier 3 motor vehicle program included extensive changes to emission standards and the regulatory requirements related to certification. This included several provisions to harmonize requirements with a similar set of standards adopted by the California Air Resources Board (California ARB). It also included a wide range of alternative measures intended to facilitate each manufacturer's efforts to make an orderly transition to meeting the Tier 3 standards nationwide. The resulting Tier 3 regulations accordingly included several variations, alternatives, and ancillary provisions. We have learned since concluding the Tier 3 rulemaking that there are several instances where the regulatory text implementing the Tier 3 program requires correction or clarification to achieve the intended result. None of the amendments are intended to expand the Tier 3 program or otherwise make substantive changes. We are therefore making the following amendments to the Tier 3 vehicle program regulations: Regulatory citation
Description§ 85.2108
Remove section to reflect a recent change to Clean Air Act section 207.§ 86.101, § 1066.301, and § 1066.305
Adjust the procedures for determining road-load parameters to more carefully align with current practice, including the option for manufacturers to use alternate methodologies that are consistent with the reference procedure, subject to good engineering judgment and EPA confirmatory testing. We are also restoring provisions describing how to develop road-load parameters for cold testing; the provisions from § 86.229 were inadvertently replaced with a default instruction to use the same values for both FTP testing and cold testing. We are also changing terminology from “coastdown” to “road-load determination” for consistency.§§ 86.095-35 and 1037.135
Revise the labeling requirement for incomplete heavy-duty vehicles to require designation of maximum fuel tank capacity only in cases where the certifying manufacturer relies on a downstream manufacturer to design and install the vehicle's fuel tanks. If the certifying manufacturer designs or installs the fuel tank, there is no need for the emission control information label to identify the appropriate fuel tank capacity.§§ 86.101 and 86.1844-01
Clarify that reporting drive-cycle metrics to confirm driver accuracy continue to be optional until vehicles are subject to Tier 3 emission standards, and revise terminology for consistency with 40 CFR 1066.425.§ 86.101
Clarify that manufacturers may continue to certify in 2022 and later model years based on carryover of emission data generated using the procedures from 40 CFR part 86, subpart B, even though we require new testing in that time frame to use the procedures in 40 CFR part 1066.§ 86.113
Revise the format of the volatility specification to rely primarily on psi units and secondarily on kPa units. The kPa figures for non-evaporative testing also need to be corrected to align with the specified psi units. These changes align with the test fuel specifications that were in place before the Tier 3 rule. We are also revising the table format for octane specifications to clarify that the both ASTM D2699 and ASTM D2700 apply for determining octane values and octane sensitivity values.§ 86.201
Clarify how the migration to testing under 40 CFR part 1066 works for cold temperature testing. This is analogous to the migration provisions for general testing in § 86.101.§ 86.213
Revise the specified tolerance for olefin concentration in the test fuel from ±0.5 percent to ±5.0 percent. This reverses an inadvertent change made in the Tier 3 final rule. We are also revising the table format for octane specifications to clarify that both ASTM D2699 and ASTM D2700 apply for determining octane values and octane sensitivity values.§ 86.513
Correct a typographical error for the 90% point in the distillation curve for gasoline test fuel. This was erroneously published as part of the Tier 3 rule with an extra “1” before the specified temperature of 148.9 °C. This change restores the temperature specification to what applied before we adopted the Tier 3 rule.§ 86.513-2004
Remove obsolete section. Fuel specifications for motorcycles are now addressed in § 86.513 (with no model year designation), so the 2004 section is removed to avoid confusion.§ 86.1801-12
Clarify how the requirements of subpart S relate to the engine and vehicle provisions in 40 CFR part 1036 and part 1037.§ 86.1803-01
Revise the definition of “averaging set” to apply to all vehicles, not only heavy-duty vehicles.§§ 86.1805-17 and 86.1811-17
Address provisions for LDV above 6,000 pounds GVWR. A new paragraph describes how these vehicles are subject to the same transitional provisions that apply for LDV at or below 6,000 pounds GVWR. We are also clarifying useful life provisions for LDV above 6,000 pounds GVWR. We described the useful life provisions based on a simple cutpoint of 6,000 pounds GVWR, which doesn't address a small number of LDV models that have higher GVWR values. Instead of changing the useful life values adopted for cold temperature emission standards, we are using the terms LDV and LLDT to characterize the vehicles that are subject to a useful life of 10 years or 120,000 miles. We are also clarifying that MDPVs are the only HDVs subject to standards under § 86.1818.( print page 9081)§ 86.1806-17
Correct the citation to California ARB's OBD regulations to refer to the entire range of relevant OBD standards.§ 86.1810-01
Clarify that the provisions for determining NMOG from measured NMHC values also apply for Tier 2 vehicles, as specified in § 1066.635, except that manufacturers may continue to use a fixed adjustment factor of 1.04.§ 86.1810-17
Clarify that the provisions for testing flexible fuel vehicles on more than just gasoline or diesel fuel do not apply for greenhouse gas standards.§ 86.1811-17(b)(8)
Clarify how to calculate and use credits for manufacturers that certify some vehicles to a useful life of 120,000 miles and other vehicles to a useful life of 150,000 miles. The main point of clarification is that vehicles certified to the shorter useful life on an interim basis may exchange emission credits with vehicles certified to either useful life, but the fleet-average standard for a given set of vehicles must correspond to the averaging set. We are also listing the emission standards that correspond to a 120,000 mile useful life rather than describing how to calculate those standards.§ 86.1811-17(b)(8)
Add a provision that Interim Tier 3 vehicles must continue to meet the 4000-mile SFTP standards for NMHC+NOX
                                 and CO from Tier 2. This requirement was included in the preamble text for the proposed rule and the final rule, but was inadvertently omitted from the regulatory text.§ 86.1811-17(b)(10)
Clarify provisions related to early credits: (1) Early credits may be used interchangeably (without adjustment) for vehicles certified to a useful life of either 120,000 miles or 150,000 miles. (2) Accumulated early credits should be used for demonstrating compliance with model year 2017 standards before doing the calculations to address proportionality relative to California emission credits. (3) Negative credits are subtracted from credit totals during the three-year period for calculating credit caps (rather than ignoring them). (4) The calculation for applying the cap/threshold relative to California credits must be corrected to use the proper baseline quantity.§ 86.1811-17(b)(11)
Clarify provisions related to early certification to Tier 3 standards: (1) Bin 70 and cleaner vehicles are considered Tier 3 vehicles on a voluntary basis and are therefore subject to the 150,000 mile useful life. (2) The transitional aspects of the Tier 3 program apply equally to vehicles certified early to the Tier 3 standards.§ 86.1811-17(g)
Revise the cold temperature testing specifications to clarify that CO and NMHC standards apply equally for certification and in-use testing, for low and high altitude, and for testing gasoline-only configurations of flexible-fuel vehicles.§ 86.1813-17
Clarify that no separate fleet-average calculation is required for demonstrating compliance with high-altitude evaporative emission standards. These standards are determined as bin values relative to the standard that applies for testing at low-altitude conditions.§ 86.1829-15
Adjust the refueling test waiver to state that it applies only for incomplete heavy-duty vehicles above 10,000 pounds GVWR, and for complete heavy-duty vehicles above 10,000 pounds GVWR with fuel tanks greater than 35 gallons, consistent with the preamble discussion in the final rule. These vehicles are the only ones that are newly subject to refueling emission standards. All smaller vehicles have already been subject to testing and certification requirements.§ 86.1829-15
Add a paragraph to preserve the provisions related to measurement of N2
                                O emissions as originally adopted at § 86.1829-01(b)(2)(iii)(G).§ 86.1829-15
Revise terminology to refer to “durability groups” rather than “durability data groups” for PM testing.§ 86.1844-01
Specify that a manufacturer's application for certification must include a description of leak families in addition to evaporative/refueling families. Since leak families are defined broadly, many manufacturers may have only a single leak family even if they have multiple evaporative/refueling families.§ 86.1845-01
Clarify that the PM measurement instructions are limited to vehicles subject to Tier 3 PM standards, as discussed in the final rule.§ 86.1846-01
Adjust the exclusion of high-mileage vehicles to the terminology changes to § 86.1845-05. This change aligns with the current practice of not including the results from testing the designated high-mileage vehicle at low altitude for making an IUVP determination for the test group.§ 86.1861-17
Clarify that the separate averaging set corresponding to 120,000 mile useful life applies only for NMOG+NOX
                                 emission standards.§§ 600.116-12 and 1066.501
Clarify that certain portions of SAE J1711 apply separately for charge-depleting and charge-sustaining operation for hybrid-electric vehicles.§ 600.117
Adjust the description to more clearly apply the interim allowance for using Tier 2 fuel to determine whether vehicles pass the “litmus test” for using derived 5-cycle testing for fuel economy, as described further below.§ 600.117
Revise the description for test fuels to clarify that cold testing may be done with the higher-volatility fuel specified in § 86.213, and that the requirement for using a common test fuel related to 5-cycle testing refers to the ethanol content of the fuel, not the whole range of test fuel specifications.§ 1037.103
Refer to § 86.1805 for useful life values as they apply for evaporative emission standards, rather than referring more broadly to useful life values in 40 CFR part 86 for “criteria pollutants”.§ 1037.104
Refer to the useful life values specified in § 86.1805 for model year 2014 vehicles for the HD GHG standards. This sets the useful life values for the HD GHG standards to a fixed value, rather than specifying a cross reference to a section of the regulations that describes changing useful life values.§§ 1065.10 and 1066.10
Allow for a one-year lead time for upgrading to test procedure changes in 40 CFR part 86 where those changes would otherwise be required immediately with the effective date of the final rule. This is consistent with existing provisions for changes to 40 CFR part 1065 and part 1066. Note that this does not delay implementation of procedures corresponding to new emission standards.§ 1065.610
Correct a sample calculation.§ 1065.710

Change from “LA-92” to “Hot-LA-92” to allow us to specify that the referenced test procedure is only the first 1435 seconds of what is known as the LA-92 driving schedule. The full cycle is 1735 seconds. This change is necessary to accomplish the intended alignment with the California ARB standards.
 We are also making various corrections for typographical errors and regulatory cross references. Note that one of these corrections is in the regulations for recreational vehicles at 40 CFR 1051.501 to maintain a proper cross reference to the driving schedules in Appendix I of 40 CFR part 86. We are also correcting a typographical error from § 86.529-98 that was published several years ago. The specified range of loaded vehicle masses corresponding to certain road-load force coefficients and inertia weights has an entry that should be listed as applying from 656 to 665 kg; the published entry mistakenly identifies the range as 565 to 665 kg. One additional issue relates to test fuel for fuel economy testing. In the Tier 3 final rule, EPA changed the certification test fuel for the Tier 3 exhaust emission standards from a 9 psi RVP fuel with no ethanol (E0) (commonly referred to as Tier 2 fuel) to a 9 psi RVP fuel with 10 percent ethanol (E10). As an interim provision, EPA permitted vehicles certifying at levels above Bin 70 to use E0 fuel for Tier 3 certification through model year 2019. The rule also permits early certification to Tier 3 requirements using 7 psi RVP E10 test fuel, commonly referred to as LEV III fuel since the California LEV III program phase-in begins with model year 2015. The rule also provides manufacturers the option to use EPA 9RVP E0 fuel or 9RVP E10 fuel for certification for cold temperature testing since California does not specify a test fuel for that testing. Under the fuel economy regulations, manufacturers use the results of their exhaust emission tests as the basis for calculating litmus test evaluations (see 40 CFR 600.115-11). However, in the Tier 3 rule EPA did not change the fuel economy test fuel specifications from E0 to E10 as was done for Tier 3 exhaust emissions. The preamble to the final rule recognized that the difference in the emission and fuel economy test fuels has the potential to require extra emission testing for the fuel economy evaluations. To minimize this burden, EPA included several provisions in the regulations to minimize this potential burden (see 40 CFR 600.117) and indicated a commitment to make any appropriate adjustments to the fuel economy regulations to accommodate the change to an E10 test fuel when the needed emission data become available. As is discussed in the final rule (79 FR 23531-23533, April 28, 2014), central to the litmus test evaluation is the requirement that data be available for all five emission test cycles and that the data be generated using the same test fuel on each cycle. Some confusion has arisen as to what cold FTP test fuel should be used in the litmus evaluations for early Tier 3 certifications using LEV III test fuel and for Tier 3 certification above Bin 70 before model year 2020. This occurs because California ARB does not specify a cold FTP test fuel and, as a transitional measure, EPA permits certification to Tier 3 Bin 125 and Bin 160 using Tier 2 fuel. This amendment clarifies that the fuel economy test fuel requirements govern for the litmus test evaluations. As indicated in the preamble to the final rule at 79 FR 23533, manufacturers may use LEV III fuel (California Phase 3) in lieu of Tier 3 fuel, but any cold FTP testing must be done using the Tier 3 cold FTP fuel. Thus, for purposes of the litmus test cold temperature testing, manufacturers must use the same test fuel (E10) as used for the other four cycles. For early Tier 3 certifications using LEV III test fuel, the cold FTP test data must be generated using Tier 3 cold FTP test fuel and in the case of the higher bins in the Tier 3 program as discussed above, the cold FTP must be based on the same fuel as used for the other four test cycles. The flexibility afforded for exhaust emission certification does not carry over to the litmus test evaluations. III. 40 CFR Part 80 Fuel Standards After promulgation of the Tier 3 final rulemaking (79 FR 23414, April 28, 2014), we discovered some typographical errors and other areas in the part 80 regulations that we believe would benefit from some additional clarity. The following sections discuss the amendments to remedy these concerns. A. Performance-Based Measurement Systems (PBMS) Section

 B. Quality Assurance Program Amendments This action also makes minor technical amendments to regulatory changes finalized in the Voluntary Quality Assurance Program Rulemaking (“QAP Rule”, 79 FR 42078, July 18, 2014). We are changing § 80.1471(d)(1) to reflect a change that industry widely requested and the public supported. In the final rulemaking we agreed to extend the notification period by an auditor for potentially invalid RINs from “within the next business day” to “within five business days.” We inadvertently neglected to change this reference in § 80.1471(d)(1) to the new “within five business days” language. In the Notice of Proposed Rulemaking for the QAP Rule, we proposed a new section at § 80.1433 that would have changed the way parties that redesignated renewable fuels for non-qualifying uses would have to retire RINs, and we proposed new product transfer document (PTD) language at § 80.1453(a)(12) to help convey the requirement to separate and/or retire RINs for parties that wished to redesignate renewable fuel for a non-qualifying use. After careful consideration of the public comments received, we chose not to finalize the proposed § 80.1433 requirements. This action is removing the extraneous reference to § 80.1433 in § 80.1453. Additionally, we are amending the PTD requirements at § 80.1453(a) to make the scope of these requirements consistent with similar requirements in other fuels programs. When we altered the scope of the PTD requirements at § 80.1453 to include both neat and blended renewable fuels, we did not intend to expand the scope of these PTD requirements to convey the information at § 80.1453 to the consumer of such fuels, in most cases. In the preamble to the final QAP Rule, we noted that these requirements were meant to apply to regulated parties (79 FR 42105, July 18, 2014). Historically, EPA has required applicable information on PTDs accompanying fuels to be conveyed through to retail stations and wholesale purchaser-consumers. The EPA has, in most cases, included language that exempts parties that are transferring title or custody of fuel to the ultimate consumer (
                        *e.g.,*
                         the PTD requirements for detergents at § 80.158 and for E15 at § 80.1503) or dispensing the fuel from a retail station or wholesale purchaser-consumer's tank to a motor vehicle or nonroad engine (
                        *e.g.,*
                         the PTD requirements for diesel and gasoline sulfur at §§ 80.590 and 80.1651, respectively). Requiring PTD language to convey information all the way down to consumers fueling at a retail station or homes receiving heating oil has little benefit to the effectiveness of EPA's fuels programs and could be quite costly for retail stations and home heating oil distributors. Therefore, we are clarifying the scope of § 80.1453 by adding an exemption to the PTD requirements for renewable fuels dispensed into motor vehicles and nonroad vehicles, engines, and equipment (to include jet engines and home heating units). Section
Description80.1426(c)(7)

 IV. Small SI Test Fuel and Bonding Provisions On June 17, 2013, EPA modified the test procedures for measuring exhaust emissions from land-based nonroad small spark-ignition engines (small SI engines) to allow for exhaust emission certification testing with a test fuel that has 10 percent ethanol as specified by California ARB (78 FR 36370). We adopted that provision on an interim basis, through model year 2019, with the expectation that we would further evaluate the appropriate test fuel for onroad and nonroad applications. The Tier 3 motor vehicle emission standards include a new certification test fuel specification that is much like California ARB's Phase 3 test fuel in that it includes 10 percent ethanol (E10). Small SI manufacturers have requested that we address the test fuel questions in a way that does not leave them uncertain about certification test fuel options starting in model year 2020. While the effort to adopt the new EPA nonroad test fuel specification lies ahead, we agree with the manufacturers that the new ethanol-based test fuel associated with the Tier 3 motor vehicle emission standards allows us to take the step of removing the expiration of the provision allowing for the use of the similar California ARB Phase 3 test fuel for small SI engines. In the future, we expect to go through a rulemaking to incorporate EPA's Tier 3 test fuel into the emission programs for small spark-ignition engines, including an assessment of how the changing test fuel relates to the stringency of the emission standards. When we adopted Phase 3 exhaust emission standards for Small SI engines in 2008, we included a new set of requirements for manufacturers to post a bond as a means of ensuring compliance with regulatory requirements (73 FR 59034, October 8, 2008). Manufacturers have been complying with the bond requirements since 2010. The bond provisions are generally working as expected, but we have found several items that should be adjusted or clarified to help with ongoing implementation, as follows: Clarify that bonds are intended to cover any improperly funded compliance obligations relative only to engines that must comply with40 CFR part 1054. The bond provisions are not intended to extend to engines that a manufacturer certifies under other EPA programs.
                    Specify that small-volume engine manufacturers and small-volume equipment manufacturers (collectively small-volume manufacturers, as defined in40 CFR 1054.801) are subject to an alternate minimum bond value of $25,000, rather than the $500,000 minimum that applies for other manufacturers. This arrangement has been the working policy under the broader allowance specified in § 1054.635(d). Codifying these terms allows us to streamline the process and remove uncertainty for small-volume manufacturers.
                    Adopt a cap on the bond value that corresponds to the applicable bond-waiver threshold. Since U.S.-based assets are roughly analogous to bond values as a measure of our ability to compel compliance (or remedy deficiencies) for the different kinds of companies, this approach provides a measure of parity or fairness between those that must post bond and those that qualify for a bond waiver based on their assets in the United States. This is consistent with the approach we took on an interim basis to specify a maximum bond value of $10 million. The new provision replaces the $10 million cap in § 1054.145(o).
                    Clarify how bond values may change within a given year, and in future years: (1) Bond values may be adjusted for a given year any time before the first importation or sale for that year; (2) once a bond value is fixed for a given year, that value may not be decreased during the year, even if sales volumes are less than anticipated; and (3) bond values may be reset with each new year, but these values must reflect actual sales volumes for the preceding three years. This arrangement allows a manufacturer to take a deliberate approach to resetting bond values if sales volumes change substantially over time.
                    Change the protocol for adjusting thresholds and bond values for inflation. Small, annual changes create confusion and an implementation burden, with very small incremental benefit. To streamline that process and still account for the cumulative effects of inflation, we are specifying that we will adjust the thresholds and bond values in 2020, and every ten years after that, using a less precise rounding protocol. These changes will not require rulemaking to take effect, but we will likely modify the regulation to reflect these periodic adjustments. V. Evaporative Test Procedures for Nonroad Equipment We specify evaporative emission standards, test procedures, and certification requirements in 40 CFR part 1060. This includes measurement procedures for fuel permeation through fuel lines and fuel tanks, and for diurnal emissions from fuel tanks. We are making the following changes to these regulations: Clarify that boat builders and other equipment manufacturers that install uncertified components are required to certify those fuel-system components as if they were component manufacturers. The original regulatory language described a requirement for equipment manufacturers to certify as equipment manufacturers if they were installing uncertified components, but we have( print page 9086)
                        found that the certification process is most straightforward if we treat them as component manufacturers.
                    The test procedures originally allowed for manufacturers to use good engineering judgment to address technical concerns related to measuring emissions from narrow-diameter fuel lines. In 2013, SAE published a voluntary consensus standard (SAE J2996) specifying measurement procedures for these narrow-diameter fuel lines. We agree that the SAE standard reflects good engineering judgment in the effort to measure emissions and are therefore incorporating this standard by reference in § 1060.515. This alternative SAE standard was designed for Small SI products, but it may be used in other applications as well; note, however, that U.S. Coast Guard requires measurements based on SAE J1527 in some cases. We are including the following clarifications and adjustments related to the specified SAE standards for all fuel-line permeation testing: (1) The test requires emission sampling over a 14-day period; (2) Two days of non-testing per week are allowed to accommodate weekend work schedules; (3) To remove any ambiguity from the published SAE standards, we are stating in our regulations that testing must occur at 23±2 °C; and (4) The final test result is based on a simple arithmetic average of measured emission values over the 14-day sampling period. These changes allow for internal consistency, and generally align with the procedures adopted by California ARB. To the extent that there are remaining differences, manufacturers may ask for approval to use different procedures under § 1060.505(c)(2) or (c)(3).
                    Correct a typographical error in the kPa pressure value for preconditioning fuel tanks for a permeation measurement. The psi value in the regulation is correct.
                    Correct the sample calculation for determining an emission result from a diurnal emission test.
                    Adjust the procedure to account for buoyancy effects in tank permeation measurements by replacing the requirement to use two identical tanks with a requirement to use a second tank that has a total volume that is within 5 percent of the test tank's total volume. This will allow manufacturers and test labs to rely on a smaller number of stock fuel tanks to make the necessary but minor corrections that result from fluctuating atmospheric pressure.
                    Adjust and clarify diurnal test procedures: (1) Add a specification for in-tank thermocouples for tracking fuel temperature for testing marine fuel tanks; (2) Replace the hourly profile of fuel temperatures with clearer specification about tracking test fuel temperature from a specified starting point to a specified (calculated) endpoint. The vapor generation should be nearly constant between test runs as long as fuel temperature continues to increase from the low temperature to the high temperature; (3) Standardize the procedure for purging the evaporative canister to prepare for testing based on a simulation of the in-use experience; this is based on engine purge for land-based applications, and on passive (ambient) purge for marine applications. This canister preconditioning is a necessary step to establish a known starting point for designing a system that meets the diurnal emission standard; and (4) Include temperature tolerance bands for the diurnal temperature cycle. Note that we are not proposing or requesting comment on changing the test procedure for marine fuel tanks to base the temperature profile on ambient temperatures instead of fuel temperatures.
                    Establish a gravimetric test method for determining mass of emissions for tanks with a diurnal emission standard of at least 2.0 grams of hydrocarbon. Emission test procedures involving an emission standard of less than 2.0 grams of hydrocarbon need the more accurate measurements available from using a flame ionization detector (FID) within a sealed enclosure. VI. Portable Fuel Containers On February 26, 2007, EPA adopted a set of requirements to reduce emissions from portable fuel containers (PFC) at 40 CFR part 59, subpart F (72 FR 8533). EPA review of PFC designs and discussions with PFC manufacturers suggest that the manufacturers may have read the provisions of 40 CFR part 59, subpart F, too narrowly and that their interpretations may have unnecessarily constrained some design approaches that may have otherwise allowed for improved in-use performance and consumer satisfaction. EPA did not intend to impact manufacturer design approaches beyond those deemed by the manufacturer as necessary to meet the emission control requirements as otherwise specified in 40 CFR part 59, and is including language in this rule to clarify regulatory requirements that apply to PFCs. Specifically, the revised regulation states that it is allowable for manufacturers to design PFCs with vents to relieve pressure, provided that the venting device is in place during emission testing, and provided that the venting device closes automatically when not in use. The modifications to 40 CFR part 59, subpart F, do not change the regulatory requirements with regard to emission standards and test procedures, but better define some elements of design and clarify how various approaches would be considered in testing. Upon seeing these modifications to the regulations, PFC manufacturers may elect to pursue design approaches they deem appropriate, which they may have thought were not available to them previously. VII. MARPOL Annex VI Implementation The Act to Prevent Pollution from Ships (APPS) implements the provisions of the International Convention for the Prevention of Pollution from Ships (MARPOL) Annex VI for the United States (33 U.S.C. 1901-1912). EPA adopted regulations in 2010 to summarize these requirements and to describe engine certification procedures and other relevant provisions as specified in APPS (75 FR 22896, April 30, 2010). MARPOL Annex VI has been amended since issuance of that 
                        **Federal Register**
                         notice to include designation of the North American ECA and the U.S. Caribbean Sea ECA and various other changes. We are amending 40 CFR part 1043 in this rulemaking to align the regulations with the amendments of MARPOL Annex VI to facilitate stakeholder compliance, and to correct certain technical errors. First, the most fundamental step in updating 40 CFR part 1043 is to cite the 2013 publication of MARPOL Annex VI and the further amendments concluded at MEPC 66 in April 2014 (see 40 CFR 1043.100). Likewise, MARPOL Annex VI was recently amended to waive the fuel-sulfur requirements for certain steamships until January 1, 2020. Part 1043 already includes such a waiver for steamships operating in the Great Lakes. We are codifying the additional temporary steamship exemption in § 1043.97. Note that covered steamships will be required to comply with the relevant sulfur limits when the exemption expires on January 1, 2020. Second, we inadvertently adopted regulatory language in 40 CFR part 1043 that differs from the language of Annex VI. For example, we originally adopted the provisions in 40 CFR part 1043 with an erroneous date, stating that the 0.10% fuel-sulfur standard applies starting January 1, 2016, which should be January 1, 2015. The Annex VI specification is enforceable with or without this correction in 40 CFR part 1043, but we want to make the change to avoid any possible confusion. We also identified the NOX
                         standards based 
                        ( print page 9087)
                        on an engine's model year; this should identify the applicability of NOX
                         standards based on the build date of new vessels, or on the date of major modifications in other circumstances. We are correcting these errors in part 1043. Third, we are adding clarifying language relating to public vessels. MARPOL Annex VI exempts public vessels from engine standards and fuel requirements. Public vessels are defined as “warships, naval auxiliary vessels, and other vessels owned or operated by a sovereign country when engaged in noncommercial service.” We want to clarify that any vessel that has a national security exemption (for engines or fuel) is automatically considered a public vessel. Fourth, we are clarifying regulatory provisions to address whether or how emission credits apply for EPA certificates and EIAPP certificates. Engine manufacturers are interested in getting an EPA certificate under 40 CFR part 1042 and an EIAPP certificate under 40 CFR part 1043 for the same engine. This would allow them maximum flexibility in selling engines to boat builders for installation in vessels used in domestic or international service. Certification to EPA standards under 40 CFR part 1042 allows manufacturers to use emission credits to make some engines with emission levels that are above the specified standard. MARPOL Annex VI and 40 CFR part 1043 do not have such an allowance. We are modifying the regulation to clarify that an engine may not be covered by both an EPA certificate and an EIAPP certificate if its certification under 40 CFR part 1042 depends on using emission credits to allow for an emission level above the specified standard. If an engine has emission levels below the specified standard and it is used to generate emission credits under 40 CFR part 1042, this would not disqualify an engine from also getting an EIAPP certificate under 40 CFR part 1043. Lastly, we are making clarifying edits to the fuels regulations under 40 CFR part 80 for MARPOL Annex VI implementation; the table below lists these edits. While some of these edits are purely corrections to typographical errors, we are also making edits to clarify the treatment of fuels under MARPOL Annex VI, Regulation 3 and Regulation 4. Regulation 3 authorizes trial programs that involve a permit allowing a ship operator to use fuel that exceeds the fuel-sulfur standards that would otherwise apply. Regulation 4 allows for flag states to approve the use of high-sulfur fuel for vessels that are equipped with technology that allows for an equivalent level of control. Specifically, we are amending the definition of “ECA marine fuel” at 40 CFR 80.2(ttt) to clarify that vessels with Regulation 3 permits or Regulation 4 equivalencies can in fact use fuel that exceeds the ECA marine fuel sulfur standard. Further, to provide producers, distributors, and marketers of fuel for use under a Regulation 3 permit or a Regulation 4 equivalency the ability to denote such fuel on their PTDs, we are amending 40 CFR 80.590 to provide these parties with express PTD statements that may be used in lieu of the statements that are currently in the regulations.

 C. Regulatory Flexibility Act (RFA) I certify that this action will not have a significant economic impact on a substantial number of small entities under the RFA. In making this determination, the impact of concern is any significant adverse economic impact on small entities. An agency may certify that a rule will not have a significant economic impact on a substantial number of small entities if the rule relieves regulatory burden, has no net burden or otherwise has a positive economic effect on the small entities subject to the rule. This rule merely clarifies and corrects existing regulatory language. We therefore anticipate no costs and therefore no regulatory burden associated with this rule. We have therefore concluded that this action will have no net regulatory burden for all directly regulated small entities. D. Unfunded Mandates Reform Act This action does not contain any unfunded mandate as described in UMRA, 2 U.S.C. 1531-1538, and does not significantly or uniquely affect small governments. The action imposes no enforceable duty on any state, local or tribal governments. Requirements for the private sector do not exceed $100 million in any one year. E. Executive Order 13132: Federalism This action does not have federalism implications. It will not have substantial direct effects on the states, on the relationship between the national government and the states, or on the distribution of power and responsibilities among the various levels of government. F. Executive Order 13175: Consultation and Coordination With Indian Tribal Governments This action does not have tribal implications as specified in Executive Order 13175. This rule merely corrects and clarifies regulatory provisions. Tribal governments would be affected only to the extent they purchase and use regulated vehicles or engines. Thus, Executive Order 13175 does not apply to this action. G. Executive Order 13045: Protection of Children From Environmental Health Risks and Safety Risks EPA interprets Executive Order 13045 as applying only to those regulatory actions that concern environmental health or safety risks that the EPA has reason to believe may disproportionately affect children, per the definition of “covered regulatory action” in section 2-202 of the Executive Order. This action is not subject to Executive Order 13045 because it does not concern an environmental health risk or safety risk. H. Executive Order 13211: Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use This action is not subject to Executive Order 13211, because it is not a significant regulatory action under Executive Order 12866. I. National Technology Transfer Advancement Act This action involves technical standards. EPA has decided to use the following voluntary consensus standards: Organization

In circumstances where the absolute difference between the mean of multiple back-to-back tests of the standard reference material and the accepted reference value of the standard reference material is greater than 0.75 times the published reproducibility of the test method, the cause of such difference must be investigated by the facility. Records of the standard reference materials measurements as well as any investigations into any exceedance of these criteria must be kept for a period of five years.

For facilities using a VCSB designated method defined test method, the Accepted Reference Value of the check standard must be determined by the respective designated test method for the fuel parameter following the guidelines of ASTM D6299. Facilities using a VCSB alternative method defined test method must use the Accepted Reference Value of the check standard as determined in a VCSB Inter Laboratory Crosscheck Program (ILCP) or a commercially available ILCP following the guidelines of ASTM D6299. If the Accepted Reference Value is not provided in the ILCP, accuracy must be assessed based upon the respective EPA-designated test method using appropriate production samples. The facility must pre-treat and assess results from the check standard testing after at least 15 testing occasions as described in section 8.2 of this standard practice. The facility must construct “MR” and “I” charts with control lines as described in section 8.4 and appropriate Annex sections of this standard practice. In circumstances where the absolute difference between the mean of multiple back-to-back tests of the standard reference material and the accepted reference value of the standard reference material is greater than 0.75 times the published reproducibility of the test method, the cause of such difference must be investigated by the facility. Participation in a VCSB ILCP at least three times a year satisfies this Accuracy SQC requirement (Examples of ILCP: ASTM Reformulated Gasoline ILCP or ASTM motor gasoline ILCP).

 Subpart C—Emission Regulations for 1994 and Later Model Year Gasoline-Fueled New Light-Duty Vehicles, New Light-Duty Trucks and New Medium-Duty Passenger Vehicles; Cold Temperature Test Procedures
 51.Section 86.201 is revised to read as follows: § 86.201
  (a) Vehicles are subject to cold temperature testing requirements as described in subpart S of this part and 40 CFR part 600. (b) 
                                *Migration to 40 CFR parts 1065 and 1066.*
                                 This subpart transitions to rely on the test procedure specifications in 40 CFR parts 1065 and 1066 as follows: (1) Through model year 2021, manufacturers may use the test procedures specified in paragraph (c) or (d) of this section or, using good engineering judgement, elements of both. For any EPA testing before model year 2022, EPA will use the manufacturer's selected procedures for applying acceptable speed-tolerance criteria. For any other parameters, EPA may conduct testing using either of the specified procedures. As allowed under this part, manufacturers may use carryover data from previous model years to demonstrate compliance with emission standards, without regard to the provisions of this section. (2) For vehicles certified before model year 2022 to any of the Tier 3 emission standards specified in subpart S of this part, manufacturers must determine overall driver accuracy based on driven cycle energy as described in 40 CFR 1066.425(j). (c) 
                                *Interim procedures.*
                                 Through model year 2021, manufacturers may certify vehicles based on data collected according to previously published cold temperature and intermediate temperature testing procedures. (d) 
                                *Long-term procedures.*
                                 Starting in model year 2022, perform testing to measure CO and NMHC emissions and determine fuel economy as described in 40 CFR part 1066; see especially 40 CFR 1066.710. We may approve the use of previously published cold temperature and intermediate temperature testing procedures for later model years as an alternative procedure under 40 CFR 1066.10(c). Perform intermediate temperature testing as follows: (1) For testing during ambient temperatures of less than 50 °F (10 °C), perform testing as described in 40 CFR part 1066, subpart H. (2) For testing at temperatures of 50 °F (10 °C) or higher, perform FTP testing as described in 40 CFR part 1066. (e) Section 86.213 describes special provisions related to test fuel specifications.

Subpart S—General Compliance Provisions for Control of Air Pollution From New and In-Use Light-Duty Vehicles, Light-Duty Trucks, and Heavy-Duty Vehicles
 56.The heading for subpart S is revised as set forth above. 57.Section 86.1801-12 is amended by: a.Revising paragraph (a)(2)(ii); b.Adding paragraph (a)(2)(iii); c.Revising paragraph (a)(3) introductory text; d.Removing paragraph (a)(4); and e.Redesignating paragraph (a)(5) as paragraph (a)(4). The revisions and addition read as follows: § 86.1801-12
  (a) * * * (2) * * * (ii) Greenhouse gas emission standards apply as specified in 40 CFR part 1037 instead of the standards specified in this subpart. (iii) The provisions of this subpart are optional for diesel-fueled Class 3 heavy-duty vehicles in a given model year if those vehicles are equipped with engines certified to the appropriate standards in § 86.007-11 for which less than half of the engine family's sales for the model year in the United States are for complete Class 3 heavy-duty vehicles. This includes engines sold to all vehicle manufacturers. If you are the original manufacturer of the engine and the vehicle, base this showing on your sales information. If you manufacture the vehicle but are not the original manufacturer of the engine, you must use your best estimate of the original manufacturer's sales information. (3) The provisions of this subpart generally do not apply to incomplete heavy-duty vehicles or to complete vehicles above 14,000 pounds GVWR (see subpart A of this part and 40 CFR parts 1036 and 1037). However, this subpart applies to such vehicles in the following cases:
 58.Section 86.1803-01 is amended by revising the definition of “Averaging set” to read as follows: § 86.1803-01
  
 *Averaging set*
                                 means a category or subcategory of vehicles within which test groups can average and trade emission credits with one another.
 59.Section 86.1805-17 is amended by revising paragraphs (a), (b), and (c) to read as follows: § 86.1805-17
  (a) 
                                *General provisions.*
                                 The useful life values specified in this section apply for all exhaust, evaporative, refueling, and OBD emission requirements described in this subpart, except for standards that are specified to apply only at certification. These useful life requirements also apply to all air conditioning leakage credits, air conditioning efficiency credits, and other credit programs used by the manufacturer to comply with the fleet-average CO2
                                 emission standards in § 86.1818. Useful life values are specified as a given number of calendar years or miles of driving, whichever comes first. (b) 
                                *Greenhouse gas pollutants.*
                                 The emission standards in § 86.1818 apply for a useful life of 10 years or 120,000 miles for LDV and LLDT and 11 years or 120,000 miles for HLDT and MDPV. Manufacturers may alternatively certify based on a longer useful life as specified in paragraph (d) of this section. (c) 
                                *Cold temperature emission standards.*
                                 The cold temperature NMHC emission standards in § 86.1811 apply for a useful life of 10 years or 120,000 miles for LDV and LLDT, and 11 years or 120,000 miles for HLDT and HDV. The cold temperature CO emission standards in § 86.1811 apply for a useful life of 5 years or 50,000 miles.
 60.Section 86.1806-17 is amended by revising paragraph (a)(8) to read as follows: § 86.1806-17
  
 (a) * * * (8) Apply thresholds for exhaust emission malfunctions from Tier 3 vehicles based on the thresholds calculated for the corresponding bin standards in the California LEV II program as prescribed for the latest model year in 13 CCR 1968.2(e) and (f). For example, for Tier 3 Bin 160 standards, apply the threshold that applies for the LEV standards. For cases involving Tier 3 standards that have no corresponding bin standards from the California LEV II program, use the next highest LEV II bin. For example, for Tier 3 Bin 50 standards, apply the threshold that applies for the ULEV standards. You may apply thresholds that are more 
                                ( print page 9105)
                                stringent than we require under this paragraph (a)(8).
 61.Section 86.1810-01 is amended by revising paragraph (o) and removing paragraph (p) to read as follows: § 86.1810-01
  
 (o) 
                                *NMOG determination procedures.*
                                 Measure NMOG emissions or determine NMOG emissions based on NMHC measurements using the procedures described in 40 CFR 1066.635. For Tier 2 and interim non-Tier 2 vehicles fueled by gasoline, manufacturers may instead measure NMHC and multiply the result by an adjustment factor of 1.04 before comparing with the NMOG standard to determine compliance with that standard.
 62.Section 86.1810-17 is amended by revising paragraph (h)(1) to read as follows: § 86.1810-17
  
 (h) * * * (1) For criteria exhaust emissions, we may identify the worst-case fuel blend for testing in addition to what is required for gasoline-fueled vehicles. The worst-case fuel blend may be the fuel specified in 40 CFR 1065.725, or it may consist of a combination of the fuels specified in 40 CFR 1065.710(b) and 1065.725. We may waive testing with the worst-case blended fuel for US06 and/or SC03 duty cycles; if we waive only SC03 testing, substitute the SC03 emission result using the standard test fuel for gasoline-fueled vehicles to calculate composite SFTP emissions.
 63.Section 86.1811-04 is amended by revising paragraph (j) to read as follows: § 86.1811-04
  
 (j) 
                                *Highway NO**X**exhaust emission standard.*
                                 The NOX
                                 emissions measured on the federal Highway Fuel Economy Test in 40 CFR 1066.840 must not be greater than 1.33 times the applicable FTP NOX
                                 standard to which the manufacturer certifies the test group. Both the measured emissions and the product of the NOX
                                 standard and 1.33 must be rounded to the nearest 0.01 g/mi before being compared.
 64.Section 86.1811-17 is amended by: a.Revising paragraph (a); b.Revising paragraphs (b)(2), (b)(8), (b)(9) introductory text, (b)(10), and (b)(11); c.Adding paragraph (b)(14); and d.Revising paragraphs (c) and (g). The revisions and addition read as follows: § 86.1811-17
  (a) 
                                *Applicability and general provisions.*
                                 This section describes exhaust emission standards that apply for model year 2017 and later light-duty vehicles, light-duty trucks, and medium-duty passenger vehicles. MDPVs are subject to all the same emission standards and certification provisions that apply to LDT4. Some of the provisions of this section also apply to heavy-duty vehicles as specified in § 86.1816. See § 86.1818 for greenhouse gas emission standards. See § 86.1813 for evaporative and refueling emission standards. This section may apply to vehicles from model years earlier than 2017 as specified in paragraph (b)(11) of this section. (b) * * * (2) Table 1 of this section describes fully phased-in Tier 3 standards that apply as specified in this paragraph (b) for the identified driving schedules. The FTP standards for NMOG+NOX
                                 apply on a fleet-average basis using discrete bin standards as described in paragraph (b)(4) of this section. The bin standards include additional emission standards for high-altitude testing and for CO emissions when testing over the FTP driving schedule. The SFTP standards for NMOG+NOX
                                 apply on a fleet-average basis as described in paragraph (b)(5) of this section. Table 1 follows: Table 1 of § 86.1811-17—Fully Phased-in Tier 3 Exhaust Emission Standards (

                                 phases in over several years as described in this paragraph (b)(8)(i). You must identify FELs as described in paragraph (b)(4) of this section and calculate a fleet-average emission level to show that you meet the FTP emission standard for NMOG+NOX
                                 that applies for each model year. For model year 2017, do not include vehicles above 6,000 pounds GVWR. Through model year 2019, you may also certify to transitional Bin 85 or Bin 110 standards, which consist of all-altitude FTP emission standards for NMOG+NOX
                                 of 0.085 or 0.110 g/mile, respectively; additional FTP standards for PM, CO, and formaldehyde apply as specified in this section for vehicles certified to Bin 125 standards. Fleet-average FTP emission standards decrease through the phase-in period as shown in the following table: Table 3 of § 86.1811-17—Declining Fleet-Average Tier 3 FTP Emission Standards for NMOG+NOX

                                     HLDT and MDPV must meet the Tier 3 standards starting with model year 2018.
 (C) You may use the SFTP stand-alone option specified in 13 CCR 1961.2 (a)(7)(A)1 of the LEV III program to demonstrate compliance with EPA's SFTP standards. Do not include any such test groups when demonstrating compliance with the phased-in fleet-average SFTP standards specified in this paragraph (b)(8)(ii). Note that this option is not available for vehicles certified to the transitional bins described in paragraph (b)(8)(i) of this section. (iii) 
                                *Interim provisions.*
                                 (A) For vehicles certified to bins higher than Bin 70 under this section through model year 2019, the Tier 2 useful life period applies as specified in § 86.1805-12 for all criteria pollutants other than PM. However, LDV and LDT1 test groups certified to bin standards above Bin 70 through model year 2019 may be included in the same averaging set with vehicles meeting standards over a 150,000 mile useful life, notwithstanding the provisions of § 86.1861-17(b)(1)(iii). Any such vehicles you include in the averaging set for 150,000 mile useful life are also subject to the fleet-average NMOG+NOX
                                 standard specified for 150,000 mile useful life; similarly, any such vehicles you include in the averaging set for 120,000 mile useful life are also subject to the fleet-average NMOG+NOX
                                 standard specified for 120,000 mile useful life. (B) You may use the E0 test fuel specified in § 86.113 through model year 2019 for gasoline-fueled vehicles certified to bins higher than Bin 70. You may not certify these vehicles using carryover data after model year 2019. (C) Vehicles must continue to comply with the Tier 2 SFTP emission standards for NMHC+NOX
                                 and CO for 4,000-mile testing as specified in § 86.1811-04(f)(1) if they are certified to transitional Bin 85 or Bin 110 standards, or if they are certified based on a fuel without ethanol, or if they are not certified to the Tier 3 p.m. standard. (iv) You may use the alternative phase-in provisions described in paragraph (b)(9) of this section to transition to the Tier 3 exhaust emission standards on a different schedule. (9) This paragraph (b)(9) describes an alternative approach to phasing in the Tier 3 emission standards for vehicles above 6,000 pounds GVWR. If you choose this approach, you must phase in the Tier 3 standards for all your vehicles above 6,000 pounds GVWR that are subject to this section according to this schedule. Under this alternative phase-in, you must meet the fully phased-in standards specified in this paragraph (b) with 40, 70, and 100 percent of your projected nationwide sales of all vehicles above 6,000 pounds GVWR that are subject to this section in model years 2019 through 2021, respectively. Any vehicles not subject to Tier 3 standards during the phase-in period must continue to comply with the Tier 2 standards in § 86.1811-04(c) and (f), including the Tier 2 SFTP emission standards for NMHC+NOX
                                 and CO for 4,000-mile testing as specified in § 86.1811-04(f)(1). Vehicles subject to Tier 2 standards under this paragraph (b)(9) are subject to the useful life provisions in § 86.1805-12 relative to exhaust emission standards. Each vehicle counting toward the phase-in percentage under this paragraph (b)(9) must meet all the standards that apply throughout the useful life as specified in § 86.1805-17, and must use the Tier 3 test fuel specified in § 86.113-15. The following exceptions and special provisions apply under this paragraph (b)(9): 
 (10) You may not use credits generated from Tier 2 vehicles for demonstrating compliance with the Tier 3 standards except as specified in this paragraph (b)(10). You may generate early credits with U.S. sales of Tier 2 vehicles in the two model years before the Tier 3 standards start to apply for a given vehicle model. Vehicles certified to the Tier 2 standards must meet all the Tier 2 requirements in § 86.1811-10, including the fleet-average Tier 2 standards. Calculate early Tier 3 emission credits as described in § 86.1861 by subtracting the appropriate Tier 2 fleet-average value for FTP 
                                ( print page 9107)
                                emissions of NMOG+NOX
                                 from 0.160 g/mile. Calculate your fleet-average value for the model year based on vehicles at or below 6,000 pounds GVWR in 2015, on all sizes of vehicles in 2016, and on vehicles above 6,000 pounds GVWR in 2017. You may use these early credits as described in § 86.1861 for demonstrating compliance with the FTP emission standard for NMOG+NOX
                                 starting in model year 2017. You may use these early credits interchangeably for vehicles certified based on a useful life of either 120,000 or 150,000 miles. For model years 2018 and later, you may use any remaining early credits for banking or trading subject to a limitation based on credits generated in California, as follows: (i) For the applicable model years in which you generate emission credits relative to California's LEV III fleet-average NMOG+NOX
                                 standard, determine the actual California sales of light-duty vehicles and light-duty trucks and the actual nationwide sales of those same vehicles. (Note: If you have a credit deficit in a given model year for your LEV III vehicles, apply the provisions of this paragraph (b)(10)(i) based on the appropriate negative credit quantity.) In 2015, count sales only from vehicle models at or below 6,000 pounds GVWR. For each model year, multiply the credits generated under the California program by the ratio of nationwide vehicle sales to LEV III vehicle sales to calculate an effective nationwide quantity. Sum these results for model years 2015 through 2017. Note that this calculation results in a maximum credit quantity based on vehicle sales in all states, even though the initial credit calculation does not include vehicle sales in California or the section 177 states. If you comply with the LEV III standards based on pooled emission credits for California and the section 177 states, use those pooled emission credits and corresponding sales for calculating the maximum credit quantity under this paragraph (b)(10)(i). (ii) You may not use more early credits generated under this paragraph (b)(10) for banking or trading to demonstrate compliance with Tier 3 emission standards than the calculated value of the effective nationwide credit quantity summed in paragraph (b)(10)(i) of this section. If your generated credits are greater than this threshold, determine the ratio by which your generated early credits exceed the threshold. Calculate an adjusted quantity of early credits generated under this paragraph (b)(10) by dividing the generated credit quantity from each model year by this ratio of generated credits relative to the applicable threshold. This adjusted quantity of credits may be used for banking or trading relative to the Tier 3 standards, subject to the five-year credit life described in § 86.1861. (11) You may certify vehicles to the Tier 3 standards starting in model year 2015. To do this, you may either sell all your LEV III vehicle models nationwide, or you may certify a subset of your fleet to alternate fleet-average emission standards as follows: (i) The alternate fleet-average FTP emission standards for NMOG+NOX
                                 are 0.100 g/mile in 2015 and 0.093 g/mile in 2016 for LDV and LDT1. (ii) The alternate fleet-average FTP emission standards for NMOG+NOX
                                 are 0.119 g/mile in 2015, 0.110 g/mile in 2016, and 0.101 g/mile in 2017 for LDT2 and HLDT. (iii) The alternate fleet-average SFTP emission standards for NMOG+NOX
                                 are 0.140 in 2015 for all vehicles, 0.110 in 2016 for all vehicles, and 0.103 in 2017 for LDT2 and HLDT. (iv) The vehicles must meet FTP and SFTP standards for PM as specified in § 86.1811-04. The PM testing provisions of § 86.1829-01(b)(1)(iii)(B) apply for these vehicles. (v) Vehicles not certified to the Tier 3 standards in a given model year must meet all the requirements that apply for Tier 2 vehicles in that model year. (vi) For cold temperature testing and for high-altitude testing, you may use the E0 fuel specified in § 86.113-04(a) or § 86.213 instead of the E10 test fuel specified in § 86.113-15. (vii) Vehicles certified under this paragraph (b)(11) to a bin standard at or below Bin 70 must be certified to a useful life of 150,000 miles. (viii) The interim provisions described in paragraph (b)(8)(iii) of this section apply for vehicles certified under this paragraph (b)(11), except that credits generated under this paragraph (b)(11) may be used interchangeably for vehicles certified based on a useful life of either 120,000 or 150,000 miles. (ix) For vehicles certified under this paragraph (b)(11), you may generate emission credits and use those credits for demonstrating compliance with Tier 3 standards as described in paragraph (b)(10) of this section or as described in § 86.1861. 
 (14) This subpart describes several ways that the transition to Final Tier 3 standards applies differently for vehicles above and below 6,000 pounds GVWR. All these distinctions apply only for LDT. LDV as a category is defined independent of GVWR, so any LDV above 6,000 pounds GVWR are subject to the same provisions that apply for LDV at or below 6,000 pounds GVWR. Where this section refers to “vehicles above 6,000 pounds GVWR,” this should be understood to include LDT above 6,000 pounds GVWR and MDPV (or HLDT and MDPV), and to exclude all LDV. (c) 
                                *Highway NMOG+NO**X**exhaust emission standard.*
                                 NMOG+NOX
                                 emissions measured on the federal Highway Fuel Economy Test in 40 CFR 1066.840 may not exceed the applicable FTP bin standard for NMOG+NOX. Demonstrate compliance with this standard for low-mileage vehicles by applying the appropriate deterioration factor. For vehicles not certified to any Tier 3 emission standards specified in paragraph (b) of this section, the provisions of § 86.1811-04(j) apply instead of this paragraph (c). 
 (g) 
                                *Cold temperature exhaust emission standards.*
                                 The standards in this paragraph (g) apply for certification and in-use vehicles tested over the test procedures specified in subpart C of this part, for testing at both low-altitude conditions and high-altitude conditions. These standards apply only to gasoline-fueled vehicles. Multi-fuel, bi-fuel or dual-fuel vehicles must comply with requirements using gasoline only. Testing with other fuels such as a high-level ethanol-gasoline blend, or testing on diesel vehicles, is not required. (1) Cold temperature CO standards. Cold temperature CO exhaust emission standards apply as follows: (i) For LDV and LDT1, the standard is 10.0 g/mile CO. (ii) For LDT2, LDT3 and LDT4, the standard is 12.5 grams per mile CO. (2) Cold temperature NMHC standards. The following fleet average cold temperature NMHC standards apply as follows:
 65.Section 86.1813-17 is amended by revising paragraphs (a)(1)(iv) and (a)(2)(i) to read as follows: § 86.1813-17
  
 (a) * * * (1) * * * (iv) Emissions are generally measured with a flame ionization detector (FID). In the case of rig, diurnal, hot soak, and running loss testing with E10 test fuel, multiply measured (unspeciated) FID values by 1.08 to account for the FID's reduced response to ethanol. However, you may instead determine total hydrocarbon equivalent for E10 testing 
                                ( print page 9108)
                                based on speciated measurements as described in § 86.143-96(c). You may use different methods (with or without speciation) for different test elements for a given test vehicle; however, you must always use the same method for diurnal and hot soak testing. In addition, any later testing with vehicles from that evaporative/refueling family must use the same method that was used for the original testing. Similarly, any evaporative/refueling families certified in later model years using carryover data must use the same method that was used for the original testing. We may do testing with or without speciation, but we will apply the 1.08 correction factor to unspeciated measurements for any of these four categories of evaporative emissions only if you also use it to determine your final test results. (2) * * * (i) The emission standard for the sum of diurnal and hot soak measurements from the two-diurnal test sequence and the three-diurnal test sequence is based on a fleet average in a given model year. You must specify a family emission limit (FEL) for each evaporative family. The FEL serves as the emission standard for the evaporative family with respect to all required diurnal and hot soak testing. Calculate your fleet-average emission level as described in § 86.1860 based on the FEL that applies for low-altitude testing to show that you meet the specified standard. For multi-fueled vehicles, calculate fleet-average emission levels based only on emission levels for testing with gasoline. You may generate emission credits for banking and trading and you may use banked or traded credits for demonstrating compliance with the diurnal plus hot soak emission standard for vehicles required to meet the Tier 3 standards, other than electric vehicles and gaseous-fueled vehicles, as described in § 86.1861 starting in model year 2017. You comply with the emission standard for a given model year if you have enough credits to show that your fleet-average emission level is at or below the applicable standard. You may exchange credits between or among evaporative families within an averaging set as described in § 86.1861. Separate diurnal plus hot soak emission standards apply for each evaporative/refueling emission family as shown for high-altitude conditions. The sum of diurnal and hot soak measurements may not exceed the following Tier 3 standards: Table 1 of § 86.1813-17—Tier 3 Diurnal Plus Hot Soak Emission Standards

 66.Section 86.1816-18 is amended by revising paragraphs (b)(1)(ii)(C), (b)(8) introductory text, (b)(12)(iii), and (c) to read as follows: § 86.1816-18
  
 (b) * * * (1) * * * (ii) * * * (C) For Class 3 vehicles, the Hot LA-92 driving schedule as specified in paragraph (c) of Appendix I of this part. 
 (8) This paragraph (b)(8) describes an alternative approach to phasing in the Tier 3 emission standards. If you choose this approach, you must phase in the Tier 3 standards for all your vehicles subject to this section according to this schedule. Under this alternative phase in, you must meet all the standards specified in paragraph (b)(2) of this section according to the phase-in schedule specified in Table 6 of this section based on the indicated percentage of your projected nationwide sales in each model year. These vehicles must meet the applicable FTP emission standard for CO and the HD-SFTP emission standards for NMOG+NOX
                                 and CO that apply for Class 2b Bin 170 and Class 3 Bin 230 as described in paragraph (b)(4) of this section. Any vehicles not subject to Tier 3 standards during the phase-in period must continue to comply with the gaseous exhaust emission standards in § 86.1816-08. Each vehicle counting toward the PM phase-in percentage under this paragraph (b)(8) in model years 2019 and 2020 must also be included in the portion of the fleet meeting the Tier 3 standards for pollutants other than PM. Each vehicle counting toward the phase-in percentage for any pollutant must use the Tier 3 test fuel specified in § 86.113-15. The following exceptions and special provisions apply under this paragraph (b)(8):

                                 emissions measured on the highway test cycle in 40 CFR 1066.840 may not exceed the applicable NMOG+NOX
                                 bin standard for FTP testing. Demonstrate compliance with this standard for low-mileage vehicles by applying the appropriate deterioration factor.
 67.Section 86.1829-15 is amended by: a.Revising paragraphs (b)(2) and (d)(1); b.Adding paragraph (d)(6); and c.Revising paragraph (e)(9). The revisions and addition read as follows: § 86.1829-15

                                demonstrate compliance with other exhaust emission standards. 
 (d) * * * (1) For vehicles subject to the Tier 3 PM standards in § 86.1811, a manufacturer may provide a statement in the application for certification that vehicles comply with applicable PM standards instead of submitting PM test data for a certain number of vehicles. However, each manufacturer must test vehicles from a minimum number of durability groups as follows: (i) Manufacturers with a single durability group subject to the Tier 3 PM standards in § 86.1811 must submit PM test data for that group. (ii) Manufacturers with two to eight durability groups subject to the Tier 3 PM standards in § 86.1811 must submit PM test data for at least two durability groups each model year. EPA will work with the manufacturer to select durability groups for testing, with the general expectation that testing will rotate to cover a manufacturer's whole product line over time. If a durability group has been certified in an earlier model year based on submitted PM data, and that durability group is eligible for certification using carryover test data, that carryover data may count toward meeting the requirements of this paragraph (d)(1), subject to the selection of durability groups. (iii) Manufacturers with nine or more durability groups subject to the Tier 3 PM standards in § 86.1811 must submit PM test data for at least 25 percent of those durability groups each model year. We will work with the manufacturer to select durability groups for testing as described in paragraph (d)(1)(ii) of this section. 
 (6) For model years 2012 through 2016, a manufacturer may provide a statement in its application for certification that vehicles comply with the applicable standards instead of measuring N2
                                O emissions. Such a statement may also be used for model year 2017 and 2018 vehicles only if the application for certification for those vehicles is based upon data carried over from a prior model year, as allowed under this subpart. No model year 2019 and later vehicles may be waived from testing for N2
                                O emissions. Vehicles certified to N2
                                O standards using a compliance statement instead of submitting test data are not required to collect and submit N2
                                O emission data under the in-use testing requirements of § 86.1845. (e) * * * (9) For complete vehicles above 10,000 pounds GVWR with fuel tanks exceeding 35 gallons nominal fuel tank capacity, and for any incomplete vehicles above 10,000 pounds GVWR, a manufacturer may provide a statement in the application for certification that vehicles comply with refueling emission standards instead of submitting test data, consistent with 40 CFR 1037.103(c).

                                 (i) Each test vehicle of a test group shall be tested in accordance with the FTP and the US06 portion of the SFTP as described in subpart B of this part, when such test vehicle is tested for compliance with applicable exhaust emission standards under this subpart. Test vehicles subject to applicable exhaust CO2
                                 emission standards under this subpart shall also be tested in accordance with the HFET as described in 40 CFR 1066.840. (ii) For vehicles subject to Tier 3 p.m. standards, manufacturers must measure PM emissions over the FTP and US06 driving schedules for at least 50 percent of the vehicles tested under paragraph (b)(5)(i) of this section. (iii) Starting with model year 2018 vehicles, manufacturers must demonstrate compliance with the Tier 3 leak standard specified in § 86.1813, if applicable, as described in this paragraph (b)(5)(iii). Manufacturers must evaluate each vehicle tested under paragraph (b)(5)(i) of this section, except that leak testing is not required for vehicles tested under paragraph (b)(5)(iv) of this section for diurnal emissions. In addition, manufacturers must evaluate at least one vehicle from each leak family for a given model year. Manufacturers may rely on OBD monitoring instead of testing as follows: (A) A vehicle is considered to pass the leak test if the OBD system completed a leak check within the previous 750 miles of driving without showing a leak fault code. (B) Whether or not a vehicle's OBD system has completed a leak check within the previous 750 miles of driving, the manufacturer may operate the vehicle as needed to force the OBD system to perform a leak check. If the OBD leak check does not show a leak fault, the vehicle is considered to pass the leak test. (C) If the most recent OBD leak check from paragraph (b)(5)(iii)(A) or (B) of this section shows a leak-related fault code as specified in § 86.1806-17(b), the vehicle is presumed to have failed the leak test. Manufacturers may perform the leak measurement procedure described in 40 CFR 1066.985 for an official result to replace the finding from the OBD leak check. (D) Manufacturers may not perform repeat OBD checks or leak measurements to over-ride a failure under paragraph (b)(5)(iii)(C) of this section. (iv) For nongaseous-fueled vehicles, one test vehicle of each evaporative/refueling family shall be tested in accordance with the supplemental 2-diurnal-plus-hot-soak evaporative emission and refueling emission procedures described in subpart B of this part, when such test vehicle is tested for compliance with applicable evaporative emission and refueling standards under this subpart. For gaseous-fueled vehicles, one test vehicle of each evaporative/refueling family shall be tested in accordance with the 3-diurnal-plus-hot-soak evaporative emission and refueling emission procedures described in subpart B of this part, when such test vehicle is tested for compliance with applicable evaporative emission and refueling standards under this subpart. The test vehicles tested to fulfill the evaporative/refueling testing requirement of this paragraph (b)(5)(iv) will be counted when determining compliance with the minimum number of vehicles as specified in Table S04-06 and Table S04-07 in paragraph (b)(3) of this section for testing under paragraph (b)(5)(i) of this section only if the vehicle is also tested for exhaust emissions under the requirements of paragraph (b)(5)(i) of this section.

                                 emission standards under this subpart shall also be tested in accordance with the HFET as described in 40 CFR 1066.840. One test vehicle from each test group shall be tested over the FTP at high altitude. The test vehicle tested at high altitude is not required to be one of the same test vehicles tested at low altitude. The test vehicle tested at high altitude is counted when determining the compliance with the requirements shown in Table S04-06 and Table S04-07 in paragraph (b)(3) of this section or the expanded sample size as provided for in this paragraph (c). (ii) For vehicles subject to Tier 3 p.m. standards, manufacturers must measure PM emissions over the FTP and US06 driving schedules for at least 50 percent of the vehicles tested under paragraph (c)(5)(i) of this section. (iii) Starting with model year 2018 vehicles, manufacturers must evaluate each vehicle tested under paragraph (c)(5)(i) of this section to demonstrate compliance with the Tier 3 leak standard specified in § 86.1813, except that leak testing is not required for vehicles tested under paragraph (c)(5)(iv) of this section for diurnal emissions. In addition, manufacturers must evaluate at least one vehicle from each leak family for a given model year. Manufacturers may rely on OBD monitoring instead of testing as described in paragraph (b)(5)(iii) of this section. (iv) For nongaseous-fueled vehicles, one test vehicle of each evaporative/refueling family shall be tested in accordance with the supplemental 2-diurnal-plus-hot-soak evaporative emission procedures described in subpart B of this part, when such test vehicle is tested for compliance with applicable evaporative emission and refueling standards under this subpart. For gaseous-fueled vehicles, one test vehicle of each evaporative/refueling family shall be tested in accordance with the 3-diurnal-plus-hot-soak evaporative emission procedures described in subpart B of this part, when such test vehicle is tested for compliance with applicable evaporative emission and refueling standards under this subpart. The vehicles tested to fulfill the evaporative/refueling testing requirement of this paragraph (c)(5)(iv) will be counted when determining compliance with the minimum number of vehicles as specified in Table S04-06 and table S04-07 in paragraph (b)(3) of this section for testing under paragraph (c)(5)(i) of this section only if the vehicle is also tested for exhaust emissions under the requirements of paragraph (c)(5)(i) of this section. 
 (f) * * * (2) For flexible-fueled vehicles certified to NMOG (or NMOG+NOX) standards, the manufacturer may ask for EPA approval to demonstrate compliance using an equivalent NMOG emission result calculated from a ratio of ethanol NMOG exhaust emissions to gasoline NMHC exhaust emissions. Ethanol NMOG exhaust emissions are measured values from testing with the ethanol test fuel, expressed as NMOG. Gasoline NMHC exhaust emissions are measured values from testing with the gasoline test fuel, expressed as NMHC. This ratio must be established during certification for each emission-data vehicle for the applicable test group. Use good engineering judgment to establish a different ratio for each duty cycle or test interval as appropriate. Identify the ratio values you develop under this paragraph (f)(2) and describe the duty cycle or test interval to which they apply in the Part II application for certification. Calculate the equivalent NMOG emission result by multiplying the measured gasoline NMHC exhaust emissions for a given duty cycle or test interval by the appropriate ratio.

 (a) Except as specified in paragraph (e) of this section, manufacturers must demonstrate compliance with greenhouse gas emission standards and determine fuel economy values using E0 gasoline test fuel as specified in 40 CFR 86.113-04(a)(1), regardless of any testing with Tier 3 test fuel under paragraph (b) of this section. (b) Manufacturers may demonstrate that vehicles comply with Tier 3 emission standards as specified in 40 CFR part 86, subpart S, during fuel economy measurements using the E0 gasoline test fuel specified in 40 CFR 86.113-04(a)(1), as long as this test fuel is used in fuel economy testing for all applicable duty cycles specified in 40 CFR part 86, subpart S. If a vehicle fails to meet a Tier 3 emission standard using the E0 gasoline test fuel specified in 40 CFR 86.113-04(a)(1), the manufacturer must retest the vehicle using the Tier 3 test fuel specified in 40 CFR 1065.710(b) (or the equivalent LEV III test fuel for California) to demonstrate compliance with all applicable emission standards over that test cycle. (c) If a manufacturer demonstrates compliance with emission standards for criteria pollutants over all five test cycles using the Tier 3 test fuel specified in 40 CFR 1065.710(b) (or the equivalent LEV III test fuel for California), the manufacturer may use test data with the same test fuel to determine whether a test group meets the criteria described in § 600.115 for derived 5-cycle testing for fuel economy labeling. Such vehicles may be tested over the FTP and HFET cycles with the E0 gasoline test fuel specified in 40 CFR 86.113-04(a)(1) under this paragraph (c); the vehicles must meet the Tier 3 emission standards over those test cycles as described in paragraph (b) of this section. (d) Manufacturers may perform testing with the appropriate gasoline test fuels specified in 40 CFR 86.113-04(a)(1), 40 CFR 86.213(a)(2), and in 40 CFR 1065.710(b) to evaluate whether their vehicles meet the criteria for derived 5-cycle testing under 40 CFR 600.115.

  (a) * * * (2) Vessels that operate only domestically and conform to the requirements of this paragraph (a)(2) are excluded from Regulation 13 of Annex VI and the NOX
                                -related requirements of this part (including the requirement to obtain an EIAPP certificate and to keep a Technical File and an Engine Book of Record Parameters). For the purpose of this exclusion, the phrase “operate only domestically” means the vessels do not enter waters subject to the jurisdiction or control of any foreign country, except for Canadian portions of the Great Lakes. (See §§ 1043.60 and 1043.70 for provisions related to fuel use by such vessels). To be excluded, the vessel must conform to each of the following provisions: 
 (iii) Any engine installed in the vessel that is not covered by an EIAPP certificate must be labeled as specified in 40 CFR 1042.135 with respect to whether it meets the requirements of Regulation 13 of Annex VI. (b) * * * (2) For non-public vessels flagged by a country that is not a party to Annex VI, the requirements of this part apply in the same manner as apply for Party vessels, except as otherwise provided in this part. For example, see § 1043.30(c)(4) for provisions related to showing compliance with this requirement without an EIAPP certificate. See § 1043.60 for specific operating requirements.
 83.Section 1043.20 is amended by revising the definitions for “2008 Annex VI”, “Emission control area (ECA)”, and “Public vessels” to read as follows: § 1043.20
  
 *2008 Annex VI*
                                 means Annex VI to the MARPOL Protocol, including the amendments from Annex 12, adopted through April 2014 (incorporated by reference in § 1043.100). This version of Annex VI does not include any amendments that may be adopted in the future. This 2008 version applies for certain provisions of this part such as those applicable for internal waters and for non-Party vessels. 
 *Emission control area (ECA)*
                                 means an area designated pursuant to Annex VI as an Emission Control Area that is in force. 
 *Public vessels*
                                 means warships, naval auxiliary vessels, and other vessels owned or operated by a sovereign country when engaged in noncommercial service. Vessels with a national security exemption under 40 CFR 80.606 or 1042.635 are deemed to be public vessels.
 84.Section 1043.40 is amended by redesignating paragraphs (d) through (f) as paragraphs (e) through (g), adding a new paragraph (d), and revising the newly redesignated paragraph (g) to read as follows: § 1043.40
  
 (d) EPA may issue both an EPA certificate and an EIAPP certificate for the same engine, as long as the manufacturer and the engine meet all applicable requirements. EPA may not issue an EIAPP certificate if the engine is certified with an FEL under 40 CFR part 1042 that is higher than the applicable NOX
                                 emission standard under Annex VI. 
 (g) This paragraph (g) applies for engines that were originally excluded from this part because they were intended for domestic use and were introduced into U.S. commerce without an EIAPP certificate. Note that such engines must be labeled as specified under 40 CFR 1042.135 to indicate that they are intended for domestic use. Such engines may be installed on vessels not intended only for domestic operation provided the engine manufacturer, vessel manufacturer, or vessel owner obtains an EIAPP certificate. Similarly, vessels originally intended only for domestic operation may be used internationally provided the engine manufacturer, vessel manufacturer, or vessel owner obtains an EIAPP certificate. The limitations for engine manufacturers described in paragraphs (a) and (d) of this section also apply for all EIAPP certificates issued under this paragraph (g). In either case, the Technical File must specify that the engine was originally certified for domestic use only, prior to being covered by an EIAPP certificate. Engine manufacturers may provide a supplemental label to clarify that the engine is no longer limited to domestic service. An engine manufacturer, vessel manufacturer, or vessel owner may also ask to apply the provisions of this paragraph (g) to engines originally certified for public vessels.

                                 as described in § 1051.235. If we allow you to certify ATVs based on engine testing, use the equipment, procedures, and duty cycle described or referenced in the section that allows engine testing. For motorcycles with engine displacement at or below 169 cc and all ATVs, use the driving schedule in paragraph (b) of appendix I to 40 CFR part 86. For all other motorcycles, use the driving schedule in paragraph (a) of Appendix I to part 86. With respect to vehicle-speed governors, test motorcycles and ATVs in their ungoverned configuration, unless we approve in advance testing in a governed configuration. We will only approve testing in a governed configuration if you can show that the governor is permanently installed on all production vehicles and is unlikely to be removed in use. With respect to engine-speed governors, test motorcycles and ATVs in their governed configuration. Run the test engine, with all emission-control systems operating, long enough to stabilize emission levels; you may consider emission levels stable without measurement if you accumulate 12 hours of operation.

Note that § 1054.145(n) allows for testing with gasoline test fuels specified by the California Air Resources Board for any individual engine family.
 Subpart G—Special Compliance Provisions
 97.Section 1054.690 is amended by adding the introductory text and revising paragraphs (a) through (f) to read as follows: § 1054.690
  This section generally applies for certifying engine manufacturers. It also applies to importers that do not certify engines as described in paragraph (j) of this section. (a) Before introducing certified engines into U.S. commerce, you must post a bond to cover any potential compliance or enforcement actions under the Clean Air Act with respect to engines certified under this part unless you demonstrate to us in your application for certification that you are able to meet any potential compliance- or enforcement-related obligations, as described in this section. Note that you might also need to post bond under this section to meet your obligations under § 1054.120(f). (b) The bonding requirements apply if you do not have long-term assets in the United States meeting any of the following thresholds: (1) A threshold of $3 million applies if you have been a certificate holder in each of the preceding ten years without failing a test conducted by EPA officials or having been found by EPA to be noncompliant under applicable regulations. (2) A threshold of $6 million applies if you are a secondary engine manufacturer. (3) A threshold of $10 million applies if you do not qualify for the smaller bond thresholds in paragraph (b)(1) or (2) of this section. (c) For the purpose of establishing your level of long-term assets under paragraph (b) of this section, include the values from your most recent balance sheet for buildings, land, and fixed equipment, but subtract depreciation and related long-term liabilities (such as a mortgage). If you have sufficient long-term assets to avoid bond payments under this section, you must identify the location of these assets in your application for certification. (d) Determine the value of the bond as follows: (1) Calculate a value based on the per-engine bond values shown in Table 1 to this section and on the projected U.S.-directed production volume from each displacement grouping for the model year. For example, if you have projected U.S.-directed production volumes of 10,000 engines with 180 cc displacement and 10,000 engines with 400 cc displacement in 2013, the calculated bond amount is $750,000. If the calculated value is less than $500,000, the appropriate bond amount is $500,000. If the calculated value exceeds the applicable threshold value specified in paragraph (b) of this section, use the applicable threshold value as the appropriate value of the bond. These values may be adjusted as described in paragraphs (d)(2) through (4) of this section. You may generally change your projected U.S.-directed production volume under § 1054.225 
                                ( print page 9115)
                                during the model year; however, you may not decrease your bond based on new projected U.S.-directed production volumes once you have imported or otherwise introduced into U.S. commerce your first engine from that model year.

200
 (2) If your estimated or actual U.S.-directed production volume increases beyond the level appropriate for your current bond payment, you must post additional bond to reflect the increased volume within 90 days after you change your estimate or determine the actual production volume. You may not decrease your bond in a given year, but you may calculate a lower bond value in a later year based on the highest actual U.S.-directed production volumes from the preceding three years. (3) If you sell engines without aftertreatment components under the provisions of § 1054.610, you must increase the per-engine bond values for the current year by 20 percent. (4) The minimum bond value is $25,000 instead of $500,000 if you are a small-volume engine manufacturer or a small-volume equipment manufacturer that has been a certificate holder in each of the preceding five years without failing a test conducted by EPA officials or having been found by EPA to be noncompliant under applicable regulations. (e) The threshold identified in paragraph (b) of this section and the bond values identified in paragraph (d) of this section are in 2008 dollars. We will adjust these values for 2020 and later, and every 10 years after that, by considering the current Consumer Price Index values published by the Bureau of Labor Statistics relative to 2008. We will generally round values for thresholds and total bond obligations as follows: (1) Round calculated values at or below $125,000 to the nearest $5,000. (2) Round calculated values above $125,000 and at or below $2.25 million to the nearest $50,000. (3) Round calculated values above $2.25 million to the nearest $500,000. (f) If you are required to post a bond under this section, you must get the bond from a third-party surety that is cited in the U.S. Department of Treasury Circular 570, “Companies Holding Certificates of Authority as Acceptable Sureties on Federal Bonds and as Acceptable Reinsuring Companies” (
                                *http://www.fms.treas.gov/​c570/​c570.html#certified*). You must maintain this bond for every year in which you sell certified engines. The surety agent remains responsible for obligations under the bond for two years after the bond is cancelled or expires without being replaced.

 (b) * * * (2) Vessel manufacturers are subject to all the requirements of this part 1060 that apply to Marine SI engines and fuel systems. However, they must certify to the emission standards specified in §§ 1060.102 through 1060.105 only if one or more of the following conditions apply: (i) Vessel manufacturers must certify fuel system components they install in their vessels if the components are not certified to meet all applicable evaporative emission standards, including both permeation and diurnal standards. This would include vessel manufacturers that make their own fuel tanks. Vessel manufacturers would need to act as component manufacturers to certify under this part 1060. (ii) Vessel manufacturers must certify their vessels only if they intend to generate or use evaporative emission credits. Vessel manufacturers would certify under part 40 CFR part 1045 using the emission-credit provisions in subpart H of that part to demonstrate compliance with the emission standard.

(2) Equipment manufacturers must certify fuel system components they install in their equipment if the components are not certified to meet applicable evaporative emission standards. Equipment manufacturers would need to act as component manufacturers to certify fuel-system components under this part 1060. (3) Engine manufacturers must meet all the requirements of this part 1060 that apply to equipment manufacturers for all fuel-system components they install on their engines. Engine manufacturers that produce Small SI engines with complete fuel systems are considered the equipment manufacturers for those engines under this part 1060.

 Subpart F—Test Procedures
 100.Section 1060.515 is amended by revising paragraphs (c) and (d) and adding paragraph (e) to read as follows: § 1060.515
  
 (c) Except as specified in paragraph (d) of this section, measure fuel line permeation emissions using the equipment and procedures for weight-loss testing specified in SAE J30 or SAE J1527 (incorporated by reference in § 1060.810). Start the measurement procedure within 8 hours after draining and refilling the fuel line. Perform the emission test over a sampling period of 14 days. You may omit up to two daily measurements in any seven day period. Determine your final emission result based on the average of measured values over the 14-day period. Maintain an ambient temperature of 23±2 °C throughout the sampling period. (d) For fuel lines with a nominal inner diameter below 5.0 mm, you may alternatively measure fuel line permeation emissions using the equipment and procedures for weight-loss testing specified in SAE J2996 (incorporated by reference in § 1060.810). Determine your final emission result based on the average of measured values over the 14-day sampling period. Maintain an ambient temperature of 23±2 °C throughout the sampling period. (e) Use good engineering judgment to test short fuel line segments. For example, you may need to join individual fuel line segments using proper connection fittings to achieve enough length and surface area for a proper measurement. Size the fuel reservoir appropriately for the tested fuel line.
 101.Section 1060.520 is amended by revising paragraphs (a)(1), (c)(1), and (d)(9) to read as follows: § 1060.520
  
 (a) * * * (1) 
                                *Pressure cycling.*
                                 Perform a pressure test by sealing the tank and cycling it between +13.8 and −3.4 kPa (+2.0 and −0.5 psig) for 10,000 cycles at a rate of 60 seconds per cycle. The purpose of this test is to represent environmental wall stresses caused by pressure changes and other factors (such as vibration or thermal expansion). If your tank cannot be tested using the pressure cycles specified by this paragraph (a)(1), you may ask to use special test procedures under § 1060.505. 
 (c) * * * (1) Obtain a second tank whose total volume is within 5 percent of the test tank's volume. You may not use a tank that has previously contained fuel or any other contents that might affect its mass stability. 
 (d) * * * (9) Record the difference in mass between the reference tank and the test tank for each measurement. This value is Mi, where i is a counter representing the number of days elapsed. Subtract Mi
                                 from Mo
                                 and divide the difference by the internal surface area of the fuel tank. Divide this g/m2
                                 value by the number of test days (using at least two decimal places) to calculate the emission rate in g/m2
                                /day. Example: If a tank with an internal surface area of 0.720 m2
                                 weighed 1.31 grams less than the reference tank at the beginning of the test and weighed 9.86 grams less than 
                                ( print page 9117)
                                the reference tank after soaking for 10.03 days, the emission rate would be— ((−1.31 g)−(−9.86 g))/0.720 m2
                                /10.03 days = 1.1839 g/m2

 102.Section 1060.525 is revised to read as follows: § 1060.525
  Use the procedures of this section to determine whether your fuel tanks meet diurnal emission standards as specified in § 1060.105. (a) Use the following procedure to measure diurnal emissions: (1) Diurnal measurements are based on representative temperature cycles, as follows: (i) Diurnal fuel temperatures for marine fuel tanks that will be installed in nontrailerable boats must undergo repeat temperature swings of 2.6 °C between nominal values of 27.6 and 30.2 °C. (ii) Diurnal fuel temperatures for other installed marine fuel tanks must undergo repeat temperature swings of 6.6 °C between nominal values of 25.6 and 32.2 °C. (iii) For fuel tanks installed in equipment other than marine vessels, the following table specifies a profile of ambient temperatures: Table 1 to § 1060.525—Diurnal Temperature Profiles for Nonmarine Fuel Tanks

 (2) Fill the fuel tank to 40 percent of nominal capacity with the gasoline specified in 40 CFR 1065.710 for general testing. (3) Install a vapor line from any vent ports that would not be sealed in the final in-use configuration. Use a length of vapor line representing the largest inside diameter and shortest length that would be expected with the range of in-use installations for the emission family. (4) If the fuel tank is equipped with a carbon canister, load the canister with butane or gasoline vapors to its canister working capacity as specified in § 1060.240(e)(2)(i) and attach it to the fuel tank in a way that represents a typical in-use configuration. Purge the canister as follows to prepare for emission measurement: (i) For marine fuel tanks, perform a single heating and cooling cycle as specified in paragraph (a)(7) of this section without measuring emissions. (ii) For nonmarine fuel tanks, establish a characteristic purge volume by running an engine with the fuel tank installed to represent an in-use configuration. Measure the volume of air flowing through the canister while the engine operates for 30 minutes over repeat cycles of the appropriate duty cycle used for certifying the engine for exhaust emissions. Set up the loaded canister for testing by purging it with the characteristic purge volume from the engine simulation run. (5) Stabilize the fuel tank to be within 2.0 °C of the nominal starting temperature specified in paragraph (a)(1) of this section. In the case of marine fuel tanks, install a thermocouple meeting the requirements of 40 CFR 86.107-96(e) in the approximate mid-volume of fuel and record the temperature at the end of the stabilization period to the nearest 0.1 °C. For sealed fuel systems, replace the fuel cap once the fuel reaches equilibrium at the appropriate starting temperature. (6) Prepare the tank for mass measurement using one of the following procedures: (i) Place the stabilized fuel tank in a SHED meeting the specifications of 40 CFR 86.107-96(a)(1) that is equipped with a FID analyzer meeting the specifications of 40 CFR 1065.260. Take the following steps in sequence: (A) Purge the SHED. (B) Close and seal the SHED. (C) Zero and span the FID analyzer. (D) Within ten minutes of sealing the SHED, measure the initial hydrocarbon concentration. This is the start of the sampling period. (ii) If your testing configuration involves mass emissions at the standard of 2.0 grams or more, you may alternatively place the stabilized fuel tank in any temperature-controlled environment and establish mass emissions as a weight loss relative to a reference fuel tank using the procedure specified in § 1060.520(d) instead of calculating it from changing hydrocarbon concentrations in the SHED. (7) Control temperatures as follows: (i) For marine fuel tanks, supply heat to the fuel tank for continuously increasing temperatures such that the fuel reaches the maximum temperature in 8 hours. Set the target temperature by adding the temperature swing specified in paragraph (a)(1) of this section to the recorded starting temperature. Hold the tank for approximately 60 minutes at a temperature no less than 0.1 °C below the target temperature. For example, if the recorded starting fuel temperature for a fuel tank that will be installed in a nontrailerable vessel is 27.1 °C, the target temperature is 29.7 °C and the fuel must be stabilized for 60 minutes with fuel temperatures not falling below 29.6 °C. For EPA testing, fuel temperatures may not go 1.0 °C above the target temperature at any point during the heating or stabilization sequence. Measure the hydrocarbon concentration in the SHED at the end of the high-temperature stabilization period. Calculate the diurnal emissions for this heating period based on the change in hydrocarbon concentration over this sampling period. Allow the fuel temperature to cool sufficiently to stabilize again at the starting temperature without emission sampling. Repeat the heating and measurement sequence for three consecutive days, starting each heating cycle no more than 26 hours after the previous start. (ii) For nonmarine fuel tanks, follow the air temperature trace from paragraph (a)(1)(iii) of this section for three consecutive 24-hour periods. Measured temperatures must follow the profile with a maximum deviation of 1.7 °C for any hourly measurement and an average temperature deviation not to exceed 1.0 °C, where the average deviation is calculated using the absolute value of each measured deviation. Start measuring emissions when you start the temperature profile. The end of the first, second, and third emission sampling periods must occur 1440±6, 2880±6, and 4320±6 minutes, respectively, after starting the measurement procedure. (8) Use the highest of the three emission levels to determine whether your fuel tank meets the diurnal emission standard. (9) For emission control technologies that rely on a sealed fuel system, you may omit the preconditioning steps in paragraph (a)(4) of this section and the last two 24-hour periods of emission 
                                ( print page 9118)
                                measurements in paragraph (a)(7) of this section. For purposes of this paragraph (a), sealed fuel systems include those that rely on pressure-relief valves, limiting flow orifices, bladder fuel tanks, and volume-compensating air bags. (b) You may subtract your fuel tank's permeation emissions from the measured diurnal emissions if the fuel tank is preconditioned with diurnal test fuel as described in § 1060.520(b) or if you use good engineering judgment to otherwise establish that the fuel tank has stabilized permeation emissions. Measure permeation emissions for subtraction as specified in § 1060.520(c) and (d) before measuring diurnal emissions, except that the permeation measurement must be done with diurnal test fuel at 28±2 °C. Use appropriate units and corrections to subtract the permeation emissions from the fuel tank during the diurnal emission test. You may not subtract a greater mass of emissions under this paragraph (b) than the fuel tank would emit based on meeting the applicable emission standard for permeation.

 111.Section 1066.10 is amended by revising paragraph (c) to read as follows: § 1066.10
  
 (c) 
                                *Exceptions.*
                                 You may use procedures other than those specified in this part as described in 40 CFR 1065.10(c). All the test procedures noted as exceptions to the specified procedures are considered generically as “other procedures.” Note that the terms “special procedures” and “alternate procedures” have specific meanings; “special procedures” are those allowed by 40 CFR 1065.10(c)(2) and “alternate procedures” are those allowed by 40 CFR 1065.10(c)(7). If we require you to request approval to use other procedures under this paragraph (c), you may not use them until we approve your request.
 Subpart B—Equipment, Measurement Instruments, Fuel, and Analytical Gas Specifications
 112.Section 1066.125 is amended by revising paragraph (a)(1) to read as follows: § 1066.125
  
 (a) * * * (1) This paragraph (a)(1) applies where we specify a minimum command and control frequency that is greater than the minimum recording frequency, such as for sample flow rates from a CVS that does not have a heat exchanger. For these measurements, the rate at which you read and interpret the signal must be at least as frequent as the minimum command and control frequency. You may record values at the same frequency, or you may record them as mean values, as long as the frequency of the mean values meets the minimum recording frequency. You must use all read values, either by recording them or using them to calculate mean values. For example, if your system reads and controls the sample flow rate at 10 Hz, you may record these values at 10 Hz, record them at 5 Hz by averaging pairs of consecutive points together, or record them at 1 Hz by averaging ten consecutive points together.

                                 Some dynamometers automatically update the parasitic loss curve for further testing. If this is not the case, compare the new parasitic loss curve to the original parasitic loss curve from the dynamometer manufacturer or the most recent parasitic loss curve you programmed into the dynamometer. You may reprogram the dynamometer to accept the new curve in all cases, and you must reprogram the dynamometer if any point on the new curve departs from the earlier curve by more than ±9.0 N (±2.0 lbf) for dynamometers capable of testing vehicles at or below 20,000 pounds GVWR, or ±36.0 N (±8.0 lbf) for dynamometers not capable of testing vehicles at or below 20,000 pounds GVWR.

 Subpart D—Coastdown
 116.Section 1066.301 is revised to read as follows: § 1066.301
  (a) The procedures described in this subpart are used to determine the road-load target coefficients (A, B, and C) for the simulated road-load equation in § 1066.210(d)(3). (b) The general procedure for determining road-load force is performing coastdown tests and calculating road-load coefficients. This procedure is described in SAE J1263 and SAE J2263 (incorporated by reference in § 1066.1010). This subpart specifies certain deviations from those procedures for certain applications. (c) Use good engineering judgment for all aspects of road-load determination. For example, minimize the effects of grade by performing coastdown testing on reasonably level surfaces and determining coefficients based on average values from vehicle operation in opposite directions over the course.
 117.Section 1066.305 is revised to read as follows: § 1066.305
  (a) For motor vehicles at or below 14,000 pounds GVWR, develop representative road-load coefficients to characterize each vehicle covered by a certificate of conformity. Calculate road-load target coefficients by performing coastdown tests using the provisions of SAE J2263 (incorporated by reference in § 1066.1010). This protocol establishes a procedure for determination of vehicle road load force for speeds between 115 and 15 km/h (71.5 and 9.3 mi/h); the final result is a model of road-load force (as a function of speed) during operation on a dry, level road under reference conditions of 20 °C, 98.21 kPa, no wind, no precipitation, and the transmission in neutral. You may use other methods that are equivalent to SAE J2263, such as equivalent test procedures or analytical modeling, to characterize road load using good engineering judgment. Determine dynamometer settings to simulate the road-load profile represented by these road-load target coefficients as described in § 1066.315. Supply representative road-load forces for each vehicle at speeds above 15 km/hr (9.3 mph), and up to 115 km/hr (71.5 mph), or the highest speed from the range of applicable duty cycles. (b) For cold temperature testing described in subpart H of this part, determine road-load target coefficients using one of the following methods: (1) You may perform coastdown tests or use other methods to characterize road load as described in paragraph (a) of this section based on vehicle operation at a nominal ambient temperature of −7 °C (20 °F). (2) You may multiply each of the road-load target coefficients determined using the procedures described in paragraph (a) of this section by 1.1 to approximate a 10 percent decrease in coastdown time for the test vehicle.
 Subpart E—Preparing Vehicles and Running an Exhaust Emission Test
 118.Section 1066.410 is amended by revising paragraph (b) introductory text to read as follows: § 1066.410
  
 (b) Place the vehicle onto the dynamometer without starting the engine (for any test cycles) or drive the vehicle onto the dynamometer (for hot-start and hot-running cycles only) and position a fan that directs cooling air to the vehicle during dynamometer operation as described in this paragraph (b). This generally requires squarely positioning the fan in front of the vehicle and directing the airflow to the vehicle's radiator. Use good engineering judgment to design and configure fans to cool the test vehicle in a way that properly simulates in-use operation, consistent with the specifications of § 1066.105. Except for the following special cases, use a road-speed modulated fan meeting the requirements of § 1066.105(c)(2) that is placed within 90 cm of the front of the vehicle and ensure that the engine compartment cover (

(iii) For charge-sustaining tests Appendix C of SAE J1711 may be used to correct final fuel economy values, CO2
                                 emissions, and carbon-related exhaust emissions, but may not be used to correct measured values for criteria pollutant emissions.

 Subpart H—Cold Temperature Test Procedures
 124.Section 1066.701 is amended by revising paragraph (a) to read as follows: § 1066.701
  (a) The procedures of this part 1066 may be used for testing at any ambient temperature. Section 1066.710 describes the provisions that apply for testing vehicles at a nominal temperature of −7 °C (20 °F); these procedures apply for motor vehicles as described in 40 CFR part 86, subpart S, and 40 CFR part 600. For other vehicles, see the standard-setting part to determine if your vehicle is required to meet emission standards outside the normal (20 to 30) °C ((68 to 86) °F) temperature range.
 125.Section 1066.710 is amended by revising paragraph (c) to read as follows: § 1066.710
  
 (c) 
                                *Heater and defroster.*
                                 During the test, operate the vehicle's interior climate control system with the heat on and set to primarily defrost the front window. Turn air conditioning off. You may not use any supplemental auxiliary heat during this testing. You may set the heater to any temperature and fan setting during vehicle preconditioning. (1) 
                                *Manual control.*
                                 Unless you rely on automatic control as specified in paragraph (c)(2) of this section, take the following steps to control heater settings: (i) Set the climate control system as follows before the first acceleration (t=20 s), or before starting the vehicle if the climate control system allows it: (A) 
                                *Temperature.*
                                 Set controls to maximum heat. For automatic control systems running in manual mode, set the heater control to 72 °F or higher. (B) 
                                *Fan speed.*
                                 Set the fan speed to full off or the lowest available speed if a full off position is not available. (C) 
                                *Airflow direction.*
                                 Direct airflow to the front window (window defrost mode). (D) 
                                *Air source.*
                                 If independently controllable, set the system to draw in outside air. (ii) At the second idle of the test cycle, which occurs 125 seconds after the start of the test, set the fan speed to maximum. Complete by 130 seconds after the start of the test. Leave temperature and air source settings unchanged. (iii) At the sixth idle of the test interval, which occurs at the deceleration to zero miles per hour 505 
                                ( print page 9123)
                                seconds after the start of the test, set the fan speed to the lowest setting that maintains air flow. Complete these changes by 510 seconds after the start of the test. You may use different vent and fan speed settings for the remainder of the test. Leave the temperature and air source settings unchanged. (2) 
                                *Automatic control.*
                                 For vehicles with automatic control systems running in automatic mode, set the temperature to 72 °F and the air flow control to the front window defrost mode for the whole test. (3) 
                                *Multiple-zone systems.*
                                 For vehicles that have separate driver and passenger controls or separate front and rear controls, you must set all temperature and fan controls as described in paragraphs (c)(1) and (2) of this section, except that rear controls need not be set to defrost the front window. (4) 
                                *Alternative test procedures.*
                                 We may approve the use of other settings under 40 CFR 86.1840 if a vehicle's climate control system is not compatible with the provisions of this section.
 Subpart I—Exhaust Emission Test Procedures for Motor Vehicles
 126.Section 1066.801 is amended by revising paragraph (c)(2) and Figure 1 in paragraph (e) to read as follows: § 1066.801
  
 (c) * * * (2) The Supplemental Federal Test Procedure (SFTP) measures the emission effects from aggressive driving and operation with the vehicle's air conditioner. The SFTP is based on a composite of three different test elements. In addition to the FTP, vehicles generally operate over the US06 and SC03 driving schedules as specified in paragraphs (g) and (h) of Appendix I of 40 CFR part 86, respectively. In the case of heavy-duty vehicles above 10,000 pounds GVWR and at or below 14,000 pounds GVWR, SFTP testing involves additional driving over the Hot LA-92 driving schedule as specified in paragraph (c) of 40 CFR part 86, Appendix I, instead of the US06 driving schedule. Note that the US06 driving schedule represents about 8.0 miles of relatively aggressive driving; the SC03 driving schedule represents about 3.6 miles of urban driving with the air conditioner operating; and the hot portion of the LA-92 driving schedule represents about 9.8 miles of relatively aggressive driving for commercial trucks. See § § 1066.815 and 1066.820. 
 (e) * * *
 
 
 127.Section 1066.815 is amended by revising paragraphs (d)(2)(ii) and (iii) to read as follows: § 1066.815
  
 (d) * * * (2) * * * (ii) Repeat the steps in paragraph (d)(1)(ii) of this section. Operate the vehicle over the first 505 seconds of the UDDS. For tests that do not include bag 4 operation, turn off the engine and simultaneously stop all hot-start sampling and recording, including background sampling, and any integrating devices at the end of the deceleration scheduled to occur 505 seconds into the hot-start UDDS. (iii) To include bag 4 measurement, operate the vehicles over the remainder of the UDDS and conclude the testing as described in paragraphs (d)(1)(iii) and (iv) of this section.
 128.Section 1066.831 is amended as follows: a.By revising paragraph (b)(3)(ii)(D). b.By adding paragraph (b)(3)(ii)(G). c.By revising paragraphs (e)(2)(i) and (iii). § 1066.831

 130.Section 1066.845 is amended by revising paragraphs (b) and (e)(2) and adding paragraph (e)(3) to read as follows: § 1066.845
  
 (b) 
                                *Test cell.*
                                 Operate the vehicle in a test cell meeting the specifications described in § 1066.835(e). You may add airflow up to a maximum of 4 miles per hour during engine idling and when the engine is off if that is needed to meet ambient temperature or humidity requirements. 
 (e) * * * (2) For manual systems, select A/C mode, set the temperature to full cold and “maximum”, set airflow to “recirculate” (if so equipped), and select the highest fan setting. During the first idle period of the SC03 driving schedule (between 186 and 204 seconds), reduce the fan speed setting to nominally 50% of maximum fan speed, set airflow to “fresh air” (if so equipped), and adjust the temperature setting to target a temperature of 55 °F (13 °C) at the dashboard air outlet. Maintain these settings for the remainder of the test. You may rely on prior temperature measurements to determine the temperature setting; however, if the system is unable to meet the 55 °F (13 °C) target, you may instead set airflow to “fresh air” and temperature to full cold. If the vehicle is equipped with technology that defaults to recirculated air at ambient temperatures above 75 °F (22 °C), that technology should remain enabled throughout the test; this may mean not setting the airflow to “recirculate” at the start and not setting the airflow to “fresh air” during the first idle period of the SC03 driving schedule. Except as specified in paragraph (e)(3) of this section, use good engineering judgment to apply the settings described in this paragraph (e)(2) equally throughout the vehicle if there are separate controls for different zones (such as rear air conditioning). (3) If the air conditioning system is designed with parameters that switch back to a default setting at key-off, perform testing in that default condition. If the air conditioning system includes any optional equipment or user controls not addressed in this paragraph (e), the manufacturer should ask us for preliminary approval to determine the appropriate settings for testing.
