PART 89_CONTROL OF EMISSIONS FROM NEW AND IN-USE NONROAD 

COMPRESSION-IGNITION ENGINES--Table of Contents

 

          Subpart C_Averaging, Banking, and Trading Provisions

 

Sec.  89.203  General provisions.



    (a) The averaging, banking, and trading programs for NOX. 

NMHC+NOX. and PM emissions from eligible nonroad engines are 

described in this subpart. Participation in these programs is voluntary.

    (b) Requirements for Tier 1 engines rated at or above 37 kW. (1) A 

nonroad engine family is eligible to participate in the averaging, 

banking, and trading program for NOX emissions and the 

banking and trading program for PM emissions if it is subject to 

regulation under subpart B of this part with certain exceptions 

specified in paragraph (b)(2) of this section. No averaging, banking, 

and trading program is available for meeting the Tier 1 HC, CO, or smoke 

emission standards specified in subpart B of this part. No averaging 

program is available for meeting the Tier 1 PM emission standards 

specified in subpart B of this part.

    (2) Nonroad engines may not participate in the averaging, banking, 

and trading programs if they are exported or are sold as Blue Sky Series 

engines as described in Sec.  89.112(f). Nonroad engines certified on a 

special test procedure under Sec.  89.114(a), may not participate in the 

averaging, banking and trading programs unless the manufacturer has 

requested that the engines be included in the averaging, banking, and 

trading programs at the time the request for the special test procedure 

is made and has been granted approval by the Administrator for inclusion 

in the averaging, banking, and trading programs.

    (3) A manufacturer may certify one or more nonroad engine families 

at NOX family emission limits (FELs) above or below the Tier 

1 NOX emission standard, provided the summation of the 

manufacturer's projected balance of all NOX credit 

transactions in a given model year is greater than or equal to zero, as 

determined under Sec.  89.207(a). A manufacturer may certify one or more 

nonroad engine families at PM FELs below the Tier 2 PM emission standard 

that will be applicable to those engine families.

    (i) FELs for NOX may not exceed the Tier 1 upper limit 

specified in Sec.  89.112(d).

    (ii) An engine family certified to an FEL is subject to all 

provisions specified in this part, except that the applicable FEL 

replaces the emission standard for the family participating in the 

averaging, banking, and trading program.

    (iii) A manufacturer of an engine family with a NOX FEL 

exceeding the Tier 1 NOX emission standard must obtain 

NOX emission credits sufficient to address the associated 

credit shortfall via averaging, banking, or trading.

    (iv) An engine family with a NOX FEL below the applicable 

Tier 1 standard may generate emission credits for averaging, banking, 

trading, or a combination thereof. An engine family

with a PM FEL below the Tier 2 standard that will be applicable to that 

engine family may generate emission credits for banking, trading, or a 

combination thereof. Emission credits may not be used to offset an 

engine family's emissions that exceed its applicable FEL. Credits may 

not be used to remedy nonconformity determined by a Selective 

Enforcement Audit (SEA) or by recall (in-use) testing. However, in the 

case of an SEA failure, credits may be used to allow subsequent 

production of engines for the family in question if the manufacturer 

elects to recertify to a higher FEL.

    (4) NOX credits generated in a given model year may be 

used to address credit shortfalls with other engines during that model 

year or in any subsequent model year except as noted under paragraph 

(b)(5)(ii) of this section. PM credits may be used to address credit 

shortfalls with Tier 2 and later engines greater than or equal to 37 kW 

and Tier 1 and later engines less than 37 kW and greater than or equal 

to 19 kW. Credits generated in one model year may not be used for prior 

model years.

    (5) The following provisions apply to the use of Tier 1 

NOX credits for showing compliance with the Tier 2 or Tier 3 

NMHC+NOX standards.

    (i) A manufacturer may use NOX credits from engines 

subject to the Tier 1 NOX standard to address 

NMHC+NOX credit shortfalls with engines in the same averaging 

set subject to Tier 1 NMHC+NOX or Tier 2 NMHC+NOX 

emission standards.

    (ii) A manufacturer may not use NOX credits from engines 

subject to the Tier 1 standards to address NMHC+NOX credit 

shortfalls with engines subject to the Tier 3 NMHC+NOX 

emission standards.

    (c) Requirements for Tier 2 and later engines rated at or above 37 

kW and Tier 1 and later engines rated under 37 kW. (1) A nonroad engine 

family is eligible to participate in the averaging, banking, and trading 

programs for NMHC+NOX emissions and PM emissions if it is 

subject to regulation under subpart B of this part with certain 

exceptions specified in paragraph (c)(2) of this section. No averaging, 

banking, and trading program is available for meeting the CO or smoke 

emission standards specified in subpart B of this part.

    (2) Nonroad engines may not participate in the averaging, banking, 

and trading programs if they are exported or are sold as Blue Sky Series 

engines as described in Sec.  89.112(f). Nonroad engines certified on a 

special test procedure under Sec.  89.114(a), may not participate in the 

averaging, banking and trading programs unless the manufacturer has 

requested that the engines be included in the averaging, banking, and 

trading programs at the time the request for the special test procedure 

is made and has been granted approval by the Administrator for inclusion 

in the averaging, banking, and trading programs.

    (3)(i) A manufacturer may certify one or more nonroad engine 

families at FELs above or below the applicable NMHC+NOX 

emission standard and PM emission standard, provided the summation of 

the manufacturer's projected balance of all NMHC+NOX credit 

transactions and the summation of the manufacturer's projected balance 

of all PM credit transactions in a given model year in a given averaging 

set is greater than or equal to zero, as determined under Sec.  

89.207(b).

    (A) FELs for NMHC+NOX and FELs for PM may not exceed the 

upper limits specified in Sec.  89.112(d).

    (B) An engine family certified to an FEL is subject to all 

provisions specified in this part, except that the applicable FEL 

replaces the emission standard for the family participating in the 

averaging, banking, and trading program.

    (C) A manufacturer of an engine family with an FEL exceeding the 

applicable emission standard must obtain emission credits sufficient to 

address the associated credit shortfall via averaging, banking, or 

trading, within the restrictions described in Sec.  89.204(c) and Sec.  

89.206(b)(4).

    (D) An engine family with an FEL below the applicable standard may 

generate emission credits for averaging, banking, trading, or a 

combination thereof. Emission credits may not be used to offset an 

engine family's emissions that exceed its applicable FEL. Credits may 

not be used to remedy

nonconformity determined by a Selective Enforcement Audit (SEA) or by 

recall (in-use) testing. However, in the case of an SEA failure, credits 

may be used to allow subsequent production of engines for the family in 

question if the manufacturer elects to recertify to a higher FEL.

    (ii)(A) In lieu of generating credits under paragraph (c)(3)(i) of 

this section, a manufacturer may certify one or more nonroad engine 

families rated under 37 kW at family emission limits (FELs) above or 

below the applicable NMHC+NOX emission standard and PM 

emission standard. The summation of the manufacturer's projected balance 

of all NMHC+NOX credit transactions and the summation of the 

manufacturer's projected balance of all PM credit transactions in a 

given model year, as determined under Sec.  89.207(b), are each allowed 

to be less than zero. Separate calculations shall be required for the 

following two categories of engines: engines rated under 19 kW and 

engines rated at or above 19 kW and under 37 kW.

    (B) For each calendar year a negative credit balance exists as of 

December 31, a penalty equal to ten percent of the negative credit 

balance as of December 31 of the calendar year shall be added to the 

negative credit balance. The resulting negative credit balance shall be 

carried into the next calendar year.

    (C) For engines rated under 19 kW, a manufacturer will be allowed to 

carry over a negative credit balance until December 31, 2003. For 

engines rated at or above 19 kW and under 37 kW, a manufacturer will be 

allowed to carry over a negative credit balance until December 31, 2002. 

As of these dates, the summation of the manufacturer's projected balance 

of all NMHC+NOX credit transactions and the summation of the 

manufacturer's projected balance of all PM credit transactions must each 

be greater than or equal to zero.

    (D) FELs for NMHC+NOX and FELs for PM may not exceed the 

upper limits specified in Sec.  89.112(d).

    (E) An engine family certified to an FEL is subject to all 

provisions specified in this part, except that the applicable 

NMHC+NOX FEL or PM FEL replaces the NMHC+NOX 

emission standard or PM emission standard for the family participating 

in the averaging and banking program.

    (F) A manufacturer of an engine family with an FEL exceeding the 

applicable emission standard must obtain emission credits sufficient to 

address the associated credit shortfall via averaging or banking. The 

exchange of emission credits generated under this program with other 

nonroad engine manufacturers in trading is not allowed.

    (G) An engine family with an FEL below the applicable standard may 

generate emission credits for averaging, banking, or a combination 

thereof. Emission credits may not be used to offset an engine family's 

emissions that exceed its applicable FEL. Credits may not be used to 

remedy nonconformity determined by a Selective Enforcement Audit (SEA) 

or by recall (in-use) testing. However, in the case of an SEA failure, 

credits may be used to allow subsequent production of engines for the 

family in question if the manufacturer elects to recertify to a higher 

FEL.

    (4)(i) Except as noted in paragraphs (c)(4)(ii), (c)(4)(iii), and 

(c)(4)(iv) of this section, credits generated in a given model year may 

be used during that model year or used in any subsequent model year. 

Except as allowed under paragraph (c)(3)(ii) of this section, credits 

generated in one model year may not be used for prior model years.

    (ii) Credits generated from engines rated under 19 kW prior to the 

implementation date of the applicable Tier 2 standards, shall expire on 

December 31, 2007.

    (iii) Credits generated from engines rated under 19 kW under the 

provisions of paragraph (c)(3)(ii) shall expire on December 31, 2003.

    (iv) Credits generated from engines rated at or above 19 kW and 

under 37 kW under the provisions of paragraph (c)(3)(ii) of this section 

shall expire on December 31, 2002.

    (5) Except as provided in paragraph (b)(3) of this section, engine 

families may not generate credits for one pollutant while also using 

credits for another pollutant in the same model year.

    (6) Model year 2008 and 2009 engines rated under 8 kW that are 

allowed to certify under this part because they meet the criteria in 40 

CFR 1039.101(c) may not generate emission credits.

    (d) Manufacturers must demonstrate compliance under the averaging, 

banking, and trading programs for a particular model year within 270 

days of the end of the model year. Except as allowed under paragraph 

(c)(3)(ii) of this section, manufacturers that have certified engine 

families to FELs above the applicable emission standards and do not have 

sufficient emission credits to offset the difference between the 

emission standards and the FEL for such engine families will be in 

violation of the conditions of the certificate of conformity for such 

engine families. The certificates of conformity may be voided ab initio 

under Sec.  89.126(c) for those engine families.
