§90.201 Applicability.(a) The requirements of this subpart C are applicable to all Phase 2 spark-ignition engines subject to the provisions of subpart A of this part except as provided in §90.103(a). These provisions are not applicable to any Phase 1 engines. Participation in the averaging, banking and trading program is voluntary, but if a manufacturer elects to participate, it must do so in compliance with the regulations set forth in this subpart. The provisions of this subpart are applicable for HC+NOX (NMHC+NOX) emissions but not for CO emissions.(b) See 40 CFR 1054.740 for special provisions for using emission credits generated under this part 90 from Phase 2 engines to demonstrate compliance with engines certified under 40 CFR part 1054.(c) To the extent specified in 40 CFR part 60, subpart JJJJ, stationary engines certified under this part and subject to the standards of 40 CFR part 60, subpart JJJJ, may participate in the averaging, banking and trading program described in this subpart.
[73 FR 59181, Oct. 8, 2008]
§90.202 Definitions.The definitions in subpart A of this part apply to this subpart. The following definitions also apply to this subpart:Averaging means the exchange of emission credits between engine families within a given manufacturer's product line.Banking means the retention of emission credits by the manufacturer generating the emission credits or obtaining such credits through trading, for use in future model year averaging or trading as permitted in this part.Emission credits represent the amount of emission reduction or exceedance, by an engine family, below or above the applicable HC+NOX (NMHC+NOX) emission standard, respectively. FELs below the standard create “positive credits,” while FELs above the standard create “negative credits.” In addition, “projected credits” refer to emission credits based on the projected applicable production volume of the engine family. “Reserved credits” are emission credits generated within a model year waiting to be reported to EPA at the end of the model year. “Actual credits” refer to emission credits based on actual applicable production volume as contained in the end-of-year reports submitted to EPA. Some or all of these credits may be revoked if EPA review of the end-of-year reports or any subsequent audit action(s) reveals problems or errors of any nature with credit computations.Trading means the exchange of emission credits between manufacturers. Back to Top
§90.203 General provisions.(a) The certification averaging, banking, and trading provisions for HC+NOX and NMHC+NOX emissions from eligible engines are described in this subpart.(b) An engine family may use the averaging, banking and trading provisions for HC+NOX and NMHC+NOX emissions if it is subject to regulation under this part with certain exceptions specified in paragraph (c) of this section. HC+NOX and NMHC+NOX credits shall be interchangeable subject to the limitations on credit generation, credit usage, and other provisions described in this subpart.(c) A manufacturer shall not include in its calculation of credit generation and may exclude from its calculation of credit usage, any new engines:(1) Which are intended to be exported, unless the manufacturer has reason or should have reason to believe that such engines have been or will be imported in a piece of equipment; or(2) Which are subject to state engine emission standards pursuant to a waiver granted by EPA under section 209(e) of the Act, unless the manufacturer demonstrates to the satisfaction of the Administrator that inclusion of these engines in averaging, banking and trading is appropriate.(d) For an engine family using credits, a manufacturer may, at its option, include its entire production of that engine family in its calculation of credit usage for a given model year.(e) (1) A manufacturer may certify engine families at Family Emission Limits (FELs) above or below the applicable emission standard subject to the limitation in paragraph (f) of this section, provided the summation of the manufacturer's projected balance of credits from all calculations and credit transactions for all engine classes in a given model year is greater than or equal to zero, as determined under §90.207. Notwithstanding the previous sentence, a manufacturer may project a negative balance of credits as allowed under §90.207(c)(2). (2) A manufacturer of an engine family with an FEL exceeding the applicable emission standard must obtain positive emission credits sufficient to address the associated credit shortfall via averaging, banking, or trading.(3) A nonhandheld engine family with an FEL below the applicable emission standard may generate positive emission credits for averaging, banking, or trading, or a combination thereof. A handheld engine family with an FEL below the applicable emission standard may generate positive emission credits for averaging or trading. A handheld engine family meeting the requirements of §90.205(a)(4) or (5), whichever is applicable, may generate positive emission credits for banking. (4) In the case of a Selective Enforcement Audit (SEA) failure, credits may be used to cover subsequent production of engines for the family in question if the manufacturer elects to recertify to a higher FEL. Credits may not be used to remedy a nonconformity determined by an SEA, except that the Administrator may permit the use of credits to address a nonconformity determined by an SEA where the use of such credits is one component of a multi-part remedy for the previously produced engines and the remedy, including the use of credits and the quantity of credits being used, is such that the Administrator is satisfied that the manufacturer has strong and lasting incentive to accurately verify its new engine emission levels and will set or reset its FELs for current and future model years so that production line compliance is assured.(5) In the case of a production line testing (PLT) failure pursuant to subpart H of this part, a manufacturer may revise the FEL based upon production line testing results obtained under subpart H of this part and upon Administrator approval pursuant to §90.122(d). The manufacturer may use credits to cover both past production and subsequent production of the engines as needed as allowed under §90.207(c)(1). (f) No Phase 2 engine family may have a HC + NOX FEL that is greater than 32.2 g/kW-hr for Class I engines, 94 g/kW-hr for Class I-A engines, 50 g/kW-hr for Class I-B engines, 26.8 g/kW-hr for Class II engines, 336 g/kW-hr for Class III engines, 275 g/kW-hr for Class IV engines, or 186 g/kW-hr for Class V engines. (g)(1) Credits generated in a given model year by an engine family subject to the Phase 2 emission requirements may only be used in averaging, banking or trading, as appropriate, for any other engine family for which the Phase 2 requirements are applicable. Credits generated in one model year may not be used for prior model years, except as allowed under §90.207(c). (2) For the 2005 model year and for each subsequent model year, manufacturers of Class II engines must provide a demonstration that the production weighted average FEL for HC+NOX (including NMHC+NOX FELs), for all of the manufacturer's Class II engines, will not exceed 13.6 g/kW-hr for the 2005 model year, 13.1 g/kW-hr for the 2006 model year and 12.6 g/kW-hr for the 2007 and each subsequent Phase 2 model year. Such demonstration shall be subject to the review and approval of the Administrator, shall be provided at the time of the first Class II certification of that model year and shall be based on projected eligible production for that model year.(h) Manufacturers must demonstrate compliance under the averaging, banking, and trading provisions for a particular model year by 270 days after the end of the model year. Except as provided in §90.207(c), an engine family generating negative credits for which the manufacturer does not obtain or generate an adequate number of positive credits by that date from the same or previous model year engines will violate the conditions of the certificate of conformity. The certificate of conformity may be voided ab initio pursuant to §90.123 for this engine family.
§90.204 Averaging.(a) Negative credits from engine families with FELs above the applicable emission standard must be offset by positive credits from engine families having FELs below the applicable emission standard, as allowed under the provisions of this subpart. Averaging of credits in this manner is used to determine compliance under §90.207(b). A manufacturer may have a negative balance of credits as allowed under §90.207(c)(2).(b) Cross-class averaging of credits is allowed across all classes of nonroad spark-ignition engines at or below 19 kW.(c) Credits used in averaging for a given model year may be obtained from credits generated in the same model year by another engine family, credits banked in previous model years, or credits of the same or previous model year obtained through trading subject to the provisions of §90.205(a). Credits generated under the previously available “Optional transition year averaging, banking, and trading program for Phase 2 handheld engines” of §§90.212 through 90.220, since repealed, may also be used in averaging. The restrictions of this paragraph notwithstanding, credits from a given model year may be used to address credit needs of previous model year engines as allowed under §90.207(c). (d) The use of credits generated under the early banking provisions of §90.205(b) is subject to regulations under this subpart.
§90.205 Banking.(a)(1) Beginning August 1, 2007, a manufacturer of a Class I engine family with an FEL below the applicable emission standard for a given model year may bank credits in that model year for use in averaging and trading. For new Class I engine families initially produced during the period starting August 1, 2003 through July 31, 2007, a manufacturer of a Class I engine family with an FEL below the applicable emission standard for a given model year may bank credits in that model year for use in averaging and trading.(2) Beginning with the 2000 model year, a manufacturer of a Class I-A or Class I-B engine family with an FEL below the applicable emission standard for a given model year may bank credits in that model year for use in averaging and trading. (3) Beginning with the 2001 model year, a manufacturer of a Class II engine family with an FEL below the applicable emission standard for a given model year may bank credits in that model year for use in averaging and trading.(4) For the 2002 model year, a manufacturer of a Class III or Class IV engine family may bank credits for use in future model year averaging and trading from only those Class III or Class IV engine families with an FEL at or below 72 g/kW-hr. Beginning with the 2003 model year, a manufacturer of a Class III or Class IV engine family with an FEL below the applicable emission standard may generate credits for use in future model year averaging and trading. (5) Beginning with the 2004 model year, a manufacturer of a Class V engine family with an FEL below the applicable emission standard may generate credits for use in future model year averaging and trading. (6) Negative credits may be banked only according to the requirements under §90.207(c).(b)(1) For Class I engine families initially produced during the period beginning with the 1999 model year and prior to August 1, 2003, a manufacturer may bank early credits for engines with HC + NOX FELs below 16.1 g/kW-hr. All early credits for such Class I engines shall be calculated against a HC + NOX level of 20.5 g/kW-hr and may continue to be calculated against the 20.5 g/kW-hr level until August 1, 2007.(2) Beginning with the 1999 model year and prior to the applicable date listed in paragraph (a) of this section for Class II engines, a manufacturer may bank early credits for all Class II engines with HC+NOX FELs below 12.1 g/kW-hr. All early credits for Class II engines shall be calculated against a HC+NOX level of 18.0 g/kW-hr.(3) Beginning with the 2000 model year and prior to the applicable date listed in paragraph (a) of this section for Class III engines, a manufacturer may bank early credits for all Class III engines with HC+NOX FELs below 72 g/kW-hr. All early credits for Class III engines shall be calculated against a HC+NOX level of 238 g/kW-hr. (4) Beginning with the 2000 model year and prior to the applicable date listed in paragraph (a) of this section for Class IV engines, a manufacturer may bank early credits for all Class IV engines with HC+NOX FELs below 72 g/kW-hr. All early credits for Class IV engines shall be calculated against a HC+NOX level of 196 g/kW-hr. (5) Beginning with the 2000 model year and prior to the applicable date listed in paragraph (a) of this section for Class V engines, a manufacturer may bank early credits for all Class V engines with HC+NOX FELs below 87 g/kW-hr. All early credits for Class V engines shall be calculated against a HC+NOX level of 143 g/kW-hr. (6) Engines certified under the early banking provisions of this paragraph are subject to all of the requirements of this part applicable to Phase 2 engines.(c) A manufacturer may bank actual credits only after the end of the model year and after EPA has reviewed the manufacturer's end-of-year reports. During the model year and before submittal of the end-of-year report, credits originally designated in the certification process for banking will be considered reserved and may be redesignated for trading or averaging in the end-of-year report and final report.(d) Credits declared for banking from the previous model year that have not been reviewed by EPA may be used in averaging or trading transactions. However, such credits may be revoked at a later time following EPA review of the end-of-year report or any subsequent audit actions.
§90.206 Trading.(a) An engine manufacturer may exchange emission credits with other engine manufacturers in trading, subject to the trading restriction specified in §90.207(c)(2). (b) Credits for trading can be obtained from credits banked in previous model years or credits generated during the model year of the trading transaction.(c) Traded credits can be used for averaging, banking, or further trading transactions, subject to §90.205(a).(d) Traded credits are subject to the limitations on use for past model years, as set forth in §90.204(c).(e) In the event of a negative credit balance resulting from a transaction, both the buyer and the seller are liable, except in cases involving fraud. Certificates of all engine families participating in a negative trade may be voided ab initio pursuant to §90.123.
[64 FR 15239, Mar. 30, 1999, as amended at 65 FR 24309, Apr. 25, 2000; 69 FR 1834, Jan. 12, 2004]
§90.207 Credit calculation and manufacturer compliance with emission standards.(a) For each engine family, HC+NOX [NMHC+NOX] certification emission credits (positive or negative) are to be calculated according to the following equation and rounded to the nearest gram. Consistent units are to be used throughout the equation.
Credits = Production×(Standard—FEL)×Power×Useful life×Load Factor
Standard = the current and applicable Small SI engine HC+NOX (NMHC+NOX) emission standard in grams per kilowatt hour as determined in §90.103 or, for early credits, the applicable emission level as specified in §90.205(b).
(b) Manufacturer compliance with the emission standards is determined on a corporate average basis at the end of each model year. A manufacturer is in compliance when the sum of positive and negative emission credits it holds is greater than or equal to zero, except that the sum of positive and negative credits may be less than zero as allowed under paragraph (c) of this section.(c)(1) If, as a result of production line testing as required in subpart H of this part, an engine family is determined to be in noncompliance pursuant to §90.710, the manufacturer may raise its FEL for past and future production as necessary. Further, a manufacturer may carry a negative credit balance (known also as a credit deficit) for the subject class and model year and for the next three model years. The credit deficit may be no larger than that created by the nonconforming family. If the credit deficit still exists after the model year following the model year in which the nonconformity occurred, the manufacturer must obtain and apply credits to offset the remaining credit deficit at a rate of 1.2 grams for each gram of deficit within the next two model years. The provisions of this paragraph are subject to the limitations in paragraph (d) of this section.(c)(2) For model years 2004 through 2007, an engine manufacturer who certifies at least one Class V engine family in a given model year may carry forward a credit deficit for four model years, but must not carry such deficit into the fifth year, provided the deficit is attributable to negative credits from its Class V engine families, subject to the following provisions: (i) Credit deficits are permitted for model years 2004 through 2007 but cannot occur for more than two consecutive model years for a given manufacturer; (ii)(A) If an engine manufacturer calculates that it has a credit deficit for a given model year, it must obtain sufficient credits from engine families produced by itself or another manufacturer in a model year no later than the fourth model year following the model year for which it calculated the credit deficit. (Example: if a manufacturer calculates that it has a credit deficit for the 2004 model year, it must obtain sufficient credits to offset that deficit from its own production or that of other manufacturers' 2008 or earlier model year engine families.); (B) An engine manufacturer carrying the deficit into the first model year following the year in which it was generated must generate or obtain credits to offset that deficit and apply them to the deficit at a rate of 1:1. An engine manufacturer carrying the deficit into the second and third model years must generate or obtain credits to offset that deficit and apply them to the deficit at a rate of 1.1:1 (i.e., deficits carried into the second and third model year must be repaid with credits equal to 110 percent of the deficit). Deficits carried into the fourth model year must be offset by credits at a rate of 1.2:1 (i.e., 120 percent of the deficit); (iii) An engine manufacturer who has a credit deficit may use credits from any class of spark-ignition nonroad engines at or below 19 kilowatts generated or obtained through averaging, banking or trading to offset the credit deficit; and, (iv) An engine manufacturer must not bank credits for future use or trade credits to another engine manufacturer during a model year in which it has generated a deficit or into which it has carried a deficit. (d) Regulations elsewhere in this part notwithstanding, if an engine manufacturer experiences two or more production line testing failures pursuant to the regulations in subpart H of this part in a given model year, the manufacturer may raise the FEL of previously produced engines only to the extent that such engines represent no more than 10 percent of the manufacturer's total eligible production for that model year, as determined on the date when the FEL is adjusted. For any additional engine families determined to be in noncompliance, the manufacturer must conduct offsetting projects approved in advance by the Administrator.(e) If, as a result of production line testing under this subpart, a manufacturer desires to lower its FEL it may do so subject to §90.708(c).(f) Except as allowed at paragraph (c) of this section, when a manufacturer is not in compliance with the applicable emission standard by the date 270 days after the end of the model year, considering all credit calculations and transactions completed by then, the manufacturer will be in violation of the regulations in this part and EPA may, pursuant to §90.123, void ab initio the certificates of engine families for which the manufacturer has not obtained sufficient positive emission credits.(g) Credit deficits. (1) Manufacturers must offset any deficits for a given model year by the reporting deadline for the fourth model year following the model year in which the deficits were generated as required in paragraph (c)(2) of this section. Manufacturers may offset deficits by generating credits or acquiring credits generated by another manufacturer. (2)(i) Failure to meet the requirements of paragraph (c)(2) of this section within the required timeframe for offsetting deficits will be considered to be a failure to satisfy the conditions upon which the certificate(s) was issued and the individual noncomplying engines not covered by the certificate must be determined according to this section. (ii) If deficits are not offset within the specified time period, the number of engines which could not be covered in the calculation to show compliance with the fleet average HC+NOX standard in the model year in which the deficit occurred and thus are not covered by the certificate must be calculated using the methodology described in paragraph (g)(2)(iii) of this section. (iii) EPA will determine the engines for which the condition on the certificate was not satisfied by designating engines in the Class V engine family with the highest HC+NOX FELs first and continuing progressively downward through the Class V engine families until a number of engines having a credit need, as calculated under paragraph (a) of this section, equal to the remaining deficit is reached. If this calculation determines that only a portion of engines in a Class V engine family contribute to the deficit situation, then EPA will designate a subset of actual engines in that engine family as not covered by the certificate, starting with the last engine produced and counting backwards. EPA may request additional information from the manufacturer that would help identify the actual engine not covered by the certificate. (iv) In determining the engine count, EPA will calculate the mass of credits based on the factors identified in paragraph (a) of this section. (3) If a manufacturer is purchased by, merges with or otherwise combines with another manufacturer, the manufacturer continues to be responsible for offsetting any deficits outstanding within the required time period. Any failure to offset the deficits will be considered to be a violation of paragraph (g)(1) of this section and may subject the manufacturer to an enforcement action for sale of engines not covered by a certificate, pursuant to paragraph (g)(2) of this section. (4) If a manufacturer that has a deficit ceases production of handheld engines, the manufacturer will be considered immediately in violation of paragraph (g)(1) of this section and may be subject to an enforcement action for sale of engines not covered by a certificate, pursuant to paragraph (g)(2) of this section (5) For purposes of calculating the statute of limitations, a violation of the requirements of paragraph (g)(1) of this section, a failure to satisfy the conditions upon which a certificate(s) was issued and hence a sale of engines not covered by the certificate, all occur upon the expiration of the deadline for offsetting deficits specified in paragraph (g)(1) of this section.

§90.208 Certification.(a) In the application for certification a manufacturer must:(1) Submit a statement that the engines for which certification is requested will not, to the best of the manufacturer's belief, cause the manufacturer to be in noncompliance under §90.207(b) when all credits are calculated for the manufacturer's engine families.(2) Declare an FEL for each engine family for HC+NOX (NMHC+NOX). The FEL must have the same number of significant digits as the emission standard.(3) Indicate the projected number of credits generated/needed for this family; the projected applicable eligible annual production volume, and the values required to calculate credits as given in §90.207.(4) Submit calculations in accordance with §90.207 of projected emission credits (positive or negative) based on annual production projections for each family.(5) (i) If the engine family is projected to have negative emission credits, state specifically the source (manufacturer/engine family or reserved) of the credits necessary to offset the credit deficit according to projected annual production.(ii) If the engine family is projected to generate credits, state specifically (manufacturer/engine family or reserved) where the projected annual credits will be applied.(iii) The manufacturer may supply the information required by this section in the form of a spreadsheet detailing the manufacturer's annual production plans and the credits generated or consumed by each engine family.(b) All certificates issued are conditional upon manufacturer compliance with the provisions of this subpart both during and after the model year of production.(c) Failure to comply with all provisions of this subpart will be considered to be a failure to satisfy the conditions upon which the certificate was issued, and the certificate may be determined to be void ab initio pursuant to §90.123.(d) The manufacturer bears the burden of establishing to the satisfaction of the Administrator that the conditions upon which the certificate was issued were satisfied or waived.(e) Projected credits based on information supplied in the certification application may be used to obtain a certificate of conformity. However, any such credits may be revoked based on review of end-of-year reports, follow-up audits, and any other verification steps considered appropriate by the Administrator. Back to Top
§90.209 Maintenance of records.(a) The manufacturer must establish, maintain, and retain the following adequately organized and indexed records for each engine family:(1) EPA engine family identification code;(2) Family Emission Limit (FEL) or FELs where FEL changes have been implemented during the model year;(3) Maximum modal power for the certification test engine;(4) Projected production volume for the model year; and(5) Records appropriate to establish the quantities of engines that constitute eligible production as defined in §90.3 for each FEL.(b) Any manufacturer producing an engine family participating in trading reserved credits must maintain the following records on an annual basis for each such engine family:(1) The engine family;(2) The actual applicable production volume;(3) The values required to calculate credits as given in §90.207;(4) The resulting type and number of credits generated/required;(5) How and where credit surpluses are dispersed; and(6) How and through what means credit deficits are met.(c) The manufacturer must retain all records required to be maintained under this section for a period of eight years from the due date for the end-of-model year report. Records may be retained as hard copy or reduced to microfilm, ADP diskettes, and so forth, depending on the manufacturer's record retention procedure; provided, that in every case all information contained in the hard copy is retained.(d) Nothing in this section limits the Administrator's discretion in requiring the manufacturer to retain additional records, or submit information not specifically required by this section, if otherwise permitted by law.(e) Pursuant to a request made by the Administrator, the manufacturer must submit to the Administrator the information that the manufacturer is required to retain.(f) EPA may, pursuant to §90.123, void ab initio a certificate of conformity for an engine family for which the manufacturer fails to retain the records required in this section or to provide such information to the Administrator upon request. Back to Top
§90.210 End-of-year and final reports.(a) End-of-year and final reports must indicate the engine family, the engine class, the actual production volume, the values required to calculate credits as given in §90.207, and the number of credits generated/required. Manufacturers must also submit how and where credit surpluses were dispersed (or are to be banked) and/or how and through what means credit deficits were met. Copies of contracts related to credit trading must be included or supplied by the broker, if applicable. The report must include a calculation of credit balances to show that the credit summation for all engines is equal to or greater than zero (or less than zero in cases of negative credit balances as permitted in §90.207(c)). For model year 2005 and later, the report must include a calculation of the production weighted average HC+NOX (including NMHC+NOX) FEL for Class II engine families to show compliance with the provisions of §90.203(g)(2).(b) The calculation of eligible production for end-of-year and final reports must be based on engines produced for the United States market, excluding engines which are subject to state emission standards pursuant to a waiver granted by EPA under section 209(e) of the Act. Upon advance written request, the Administrator will consider other methods to track engines for credit calculation purposes that provide high levels of confidence that eligible production or sales are accurately counted.(c)(1)End-of-year reports must be submitted within 90 days of the end of the model year to: Manager, Engine Compliance Programs Group (6403-J), U.S. Environmental Protection Agency, Washington, DC 20460.(2) Unless otherwise approved by the Administrator, final reports must be submitted within 270 days of the end of the model year to: Manager, Engine Compliance Programs Group (6403-J), U.S. Environmental Protection Agency, Washington, DC 20460.(d) Failure by a manufacturer to submit any end-of-year or final reports in the specified time for any engines subject to regulation under this part is a violation of §90.1003(a)(2) and section 213(d) of the Clean Air Act for each engine.(e) A manufacturer generating credits for banking only who fails to submit end-of-year reports in the applicable specified time period (90 days after the end of the model year) may not use the credits until such reports are received and reviewed by EPA. Use of projected credits pending EPA review is not permitted in these circumstances.(f) Errors discovered by EPA or the manufacturer in the end-of-year report, including errors in credit calculation, may be corrected in the final report.(g) If EPA or the manufacturer determines that a reporting error occurred on an end-of-year or final report previously submitted to EPA under this section, the manufacturer's credits and credit calculations must be recalculated. Erroneous positive credits will be void except as provided in paragraph (h) of this section. Erroneous negative credit balances may be adjusted by EPA.(h) If EPA review determines a reporting error in the manufacturer's favor (that is, resulting in an increased credit balance) or if the manufacturer discovers such an error within 270 days of the end of the model year, EPA shall restore the credits for use by the manufacturer.(i) For 2007 and later model years, include in your end-of-year and final reports an accounting to show a separate balance of emission credits for handheld and nonhandheld engines. Use your best judgment to differentiate your current balance of banked credits for handheld and nonhandheld engines. You may exchange handheld and nonhandheld credits to demonstrate compliance with the requirements of this part 90. However, emission credits you generate for banking under this part 90 will be restricted for engines subject to the requirements of 40 CFR part 1054.
