§ 2401. Definitions.

(a) [No Change, except add the following new defini tions. Note: The

numbered order of each definition within the sectio n will be modified to reflect a proper alphabetical listing in the final version of these regulations.]

“Eight-hour workday” means the zero-emission small off-road equipment manufacturer specified operational sequence of a pa rticular type of equipment over an eight-hour period. The operational sequenc e reflects periods of equipment use, and applicable battery recharging an d exchanging.

“Professional level” means the degree of equipment performance expected by commercial operators. For zero-emission small off- road equipment, the degree of performance is based on durability test power lo ading, supplied battery capacity, cutter speed, as applicable, and other pe rformance requirements or parameters that are specific to a particular equipm ent type.

“Standard battery package” means the manufacturer-s pecified combination of battery(ies) and battery charger(s) required for an individual unit of zero-emission equipment to perform one hour of continuous operati on, allowing for battery- 2 -

The one-hour periods of contin uous operation and battery exchanges are repeated in cycles over the course of an eight-hour workday.

“Zero-emission equipment credits” means the amount of emission reductions generated by using zero-emission small off-road equ ipment in place of small spark-ignition off-road equipment. Zero-emission e quipment credits are calculated pursuant §2408.1 and approved by ARB. E lectrically powered equipment that are powered exclusively through an e lectrical cord and require continuous external power generation for operation are not eligible for such

credits.

“Zero-emission equipment engine family” means the e ngine family for zeroemission small off-road equipment based on characte ristics of the equipment, its emissions, and its power source, which may be an el ectric motor, and its energy storage device, which may be a battery.

Credits = (Standard – FEL) x Sales x Power x EDP x Load Factor

Where: Standard = the current and applicable small off-roa d engine HC+NO

x (NMHC+NO

x ) or Particulate Matter emission standard as determ ined in Section

2403. FEL = the family emission limit for the engine fami ly in grams per brake-horsepower hour or g/kW-hr as applicable. Sales = eligible sales as defined in section 2401. Annual sales projections are used to project credit availability for initial cer tification. Actual sales volume is used in determining actual credits for end-of-year compliance determination. Power = the sales weighted maximum modal power, in horsepower or kilowatts as applicable. This is determined by multiplying t he maximum modal power of each configuration within the family by its eligibl e sales, summing across all configurations and dividing by the eligible sales o f the entire family. Manufacturers may use an alternative if approved by the Executive Officer (for example, maximum modal power of the test engine). EDP = the Emissions Durability Period for which the engine family was certified

in hours

. Load Factor = For Test Cycle A and Test Cycle B, th e Load Factor = 47% (i.e., 0.47). For Test Cycle C, the Load Factor = 85% (i. e., 0.85). For approved alternate test procedures, the load factor must be calculated according to the following formula:

(3) If, as a result of production line testing as required in section 2407, an engine family is determined to be in noncompliance, the manufacturer may raise its recertify to a higher FEL for past and future production as necessary. Further, a manufacturer m ay carry a negative credit balance (known also as a credit deficit) for the su bject class and model year forward to the next model year. 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 no nconformity occurred, the- 9 -

The provisions of this paragraph are subject to the limitations in paragraph (4) of this section.

(4) Regulations elsewhere in this section notwith standing, if an engine manufacturer experiences two or more product ion line testing failures pursuant to the regulations in section 2407 of this article in a given model year, the manufacturer may raise the FEL of recertify previously produced engines to a higher FEL only to the extent that such engines represent no m ore than 10% of the manufacturer’s total eligible sales for that mo del year. For any additional engines determined to be in noncompliance, the manu facturer must conduct offsetting projects approved in advance by the Exec utive Officer.

(5) If, as a result of production line testing un der section 2407, a manufacturer desires to lower its FEL, it may do so subject to Executive Officer approval and demonstration that the family would me et the new FEL in the production line testing using the existing data. A manufacturer may lower their FEL at most once per model year.

2. Durability testing must be performed in an equip ment configuration that is representative of actual oper ation of the equipment by the end user (i.e., using standard battery package cycl ing).

3. The minimum battery durability/life cycle is bas ed on the maximum durability power specified and the equi valent engine duty cycle (i.e., handheld equipment is 85 percent at 100 perc ent load rated speed, and 15 percent at minimum load idle speed; a walk-behin d lawn mower is a fivemode test cycle [without an idle mode] at 3,060 rpm ).

(E) In order to generate zero-emission equipment cr edits, manufacturers of battery-powered zero-emission smal l off-road equipment must provide the ultimate purchaser with a standard batt ery package, as defined in

section 2401.

(F) 1. A manufacturer of zero-emission small off-r oad equipment must include in the certification applica tion, a description of an operational sequence over the eight-hour workday fo r the applicable zeroemission equipment engine family.

2. Total time for battery exchanges during an eigh t-hour workday for an engine family certified as a zero-em ission equipment engine family must not exceed the total refueling time for that of an equivalently performing professional-level gasoline-powered piec e of equipment during an eight-hour period of operation.

(G) Manufacturers must demonstrate compliance under the averaging, banking, and trading provisions for a pa rticular model year within 270 days after the end of the model year.

(H) 1. Batteries in an equipment manufacturer’s or iginal standard battery package must be identified with un ique part numbers that differ from the part numbers of any applicable replacement batteries.

2. Replacement batteries cannot be used to genera te zeroemission equipment credits.- 16 -

(1) Fifty percent of negative credits from engine f amilies with FELs above the applicable emission standard may be offse t by positive zero-emission equipment credits, as allowed under the provisions of section 2408.1. The remaining negative credits must be offset by positi ve certification emission credits. Averaging of credits in this manner is us ed to determine compliance under subsection 2408.1(f)(2).

(2) Subject to the limitations above, zero-emissio n equipment credits used in averaging for a given model year may be obt ained from zero-emission equipment credits banked in previous model years, o r zero-emission equipment credits of previous model years obtained through tr ading. (3) Zero-emission equipment credits generated from zero-emission small off-road equipment that performs equivalently to professional-level sparkignition engine powered equipment, with a displacem ent of 80cc or less, may only be used to offset emissions from other gasolin e-powered equipment with a displacement of 80cc or less.

(4) Zero-emission equipment credits generated from zero-emission small off-road equipment that performs equivalently to spark-ignition engine powered equipment, with a displacement between 80cc and 225cc, may only be used to offset emissions from other gasoline-powere d equipment with a displacement between 80cc and 225cc.

(d) Banking.

(1) Beginning with the 2010 model year, a manufactu rer of zeroemission small off-road equipment that meets the ze ro-emission equipment credit requirements may bank credits for that engin e family in the model year of certification for use in future years in averaging and trading.

(2) A manufacturer of zero-emission small off-road equipment may bank zero-emission equipment credits only after the end of the model year and after ARB has reviewed the manufacturer's end-of-ye ar 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 re-designated for trading in the end-of- year report and final report.

(3) Zero-emission equipment credits may be banked f or up to five years.

(4) Unused zero-emission equipment credits after fi ve years will expire and may no longer be used toward offsetting negativ e certification emission credits from other engine families.- 17 -

(1) Zero-emission equipment credits for trading can be obtained from zero-emission equipment credits banked in previous model years.

(2) Traded zero-emission equipment credits can be u sed for averaging or banking for up to five years from the time of ze ro-emission equipment credit generation.

(f) Credit calculation and manufacturer compliance with emission standards. For each engine family, HC+NO

x and Particulate Matter zero-emission equipment credits are to be calculated according to the following equation and rounded to the nearest gram. Consistent units are to be used throughout the equation.

Zero-Emission Equipment Credits = Exhaust Standard x Sales x Power x EDP x

Load Factor

Where:

Exhaust Standard = the current and applicable small off-road engine HC+NO

x (NMHC+NO

x ), or Particulate Matter, exhaust emission standard , expressed in grams per kilowatt-hour (g/kW-hr), as determined in section 2403, based on the engine displacement of equivalently performing, pro fessional level, gasolinepowered equipment.

Sales = eligible sales as defined in section 2401. Annual sales projections are used to project credit availability for initial cer tification. Actual sales volume is used in determining actual credits for end-of-year compliance determination.

Power = the product of the battery capacity deliver ed in one hour and the motor efficiency, expressed in kilowatts (kW). The motor efficiency is a declared value

from the motor manufacturer.

Battery capacity = the total amount of electrical e nergy available in the equipment’s standard battery package, expressed in Watt-hours (Wh).

EDP = the Emissions Durability Period for which the engine family was certified, expressed in hours (hr).

Load Factor = For Test Cycle A and Test Cycle B, th e Load Factor = 47 percent (i.e., 0.47). For Test Cycle C, the Load Factor = 85 percent (i.e., 0.85). For alternate test procedures, a manufacturer must subm it for approval an alternative method for calculating the load factor.- 18 -
