I. Guidance
This chapter describes the minimum criteria and requirements for the Carl Moyer Memorial Air Quality Standards Attainment Program’s (Carl Moyer Program or Moyer Program) mobile, portable, stationary, off-road compression-ignition (CI or diesel), spark-ignition, and large spark-ignition (LSI) projects such as construction, agricultural, and industrial equipment. For funding guidance on agricultural projects that are funded through the Moyer Program, please refer to the Funding Agricultural Replacement Measures for Emission Reductions (FARMER) guidelines. Air quality management districts or air pollution control districts (air districts) may set more stringent requirements based upon local priorities.
Please note that to fund projects in this category, Chapters 2 and 3 include general provisions and administrative requirements. Appendices A-E provide additional supporting information.
A. Projects Eligible for Funding
The following off-road equipment projects may be eligible for funding:
1. Repower of Existing Equipment. The replacement of the existing engine with a newer emission-certified engine instead of rebuilding the existing engine to its original specifications.
2. Retrofit Purchase. The installation of a California Air Resources Board (CARB) verified emission control system on an existing engine. Examples include, but are not limited to, particulate filters and diesel oxidation catalysts.
3. Equipment Replacement. The purchase of new or used equipment with an engine certified to the current emission standard Tier to replace an older, fully functional piece of equipment that is to be scrapped.
4. Infrastructure. See the infrastructure chapter (Chapter 10) for details regarding applicant eligibility and project types for infrastructure in support of off-road equipment.
Please see sections C and D of this chapter for determining maximum grant amounts and minimum eligibility requirements for all off-road project categories. Off-road eligible projects exclude marine, locomotive, and lawn and garden projects. For off-road locomotive projects see Chapter 6, marine projects see Chapter 7, and for lawn and garden projects see Chapter 9.
B. Engine Emission Standards
CARB and the United States Environmental Protection Agency (U.S. EPA) have adopted regulations for exhaust emission standards for new off-road CI and LSI engines and equipment. For reference, Tables 5-9 and 5-10 in the references section, summarize the hydrocarbon (HC), oxides of nitrogen (NOx), and particulate matter (PM) standards in grams per brake- horsepower-hour (g/bhp-hr) and grams per kilowatt-hour (g/kW-hr) for off-road CI Tier 1, 2, 3, and 4 engines. The actual standards, in grams per kilowatt-hour (g/kW-hr), may be found in the California Code of Regulations (CCR), title 13, Sections 6/11/2026 5-2 OFF-ROAD EQUIPMENT
2420, et seq. Table 5-11 summarizes the exhaust emission standards for LSI engines. The complete emission standards for LSI engines may be found in the CCR, title 13, Sections 2430, et seq.
C. Determining Funding Amounts
1. Maximum Funding
The maximum amount of funding available to a project is limited by a costeffectiveness limit (see Appendix E). In addition to cost-effectiveness limits, Table 5-1 summarizes the maximum eligible funding for each project type as a percentage. All projects are also subject to the cost-effectiveness limits specified in Appendix E.
Table 5-1
Maximum Percentage Eligible for Moyer Program Off-Road Projects Project Maximum Percentage Eligible
Diesel repower 85%
LSI repower 85%
Repower to zero-emission 85%
Replacement to zero-emission 85%
Mobile equipment replacement 80%
Portable equipment replacement (excludes
stationary)
80%
Retrofit 100%
Optional cost-share plus up for fleets taking
voluntary action for zero-emission CARB Programs
or Regulations
15%
CARB has adopted in-use fleet rules affecting equipment with off-road CI and off- road LSI engines. For equipment subject to these rules, additional limitations may apply according to Sections F through L of this chapter.
2. Project Life
(A) For maximum project life see Table 5-2
(B) The maximum project life does not consider regulatory requirements that may shorten the eligible project life. CARB Programs or regulatory requirements may reduce actual project lives below these maximum values. (1) Districts have the flexibility to fund zero-emission projects up to the maximum project life and maximum eligible incentive amount for fleets not subject to or taking voluntary action for CARB’s programs or regulations 6/11/2026 5-3 OFF-ROAD EQUIPMENT
that do not currently have an EPA waiver or authorization. (C) The minimum project life allowed is one year
Table 5-2 Maximum Project Life
Type Project Life
Repower only (no retrofit) 7 years
Farm equipment (all projects- refer to FARMER) 10 years(1) Replacement and repower to zero-emission 10 years
Retrofit only 5 years
Replacement excavators 3 years
Replacement skid steer loaders 3 years
Replacement rough terrain forklifts 3 years
Replacement all other non-farm (existing diesel only) 5 years Replacement all other non-farm (existing LSI only) 3 years (1) Agricultural equipment projects refer to FARMER guidelines. (D) Project life can vary between the minimum and maximum amount based on various factors, including air district funding, cost effectiveness of the project, and regulatory compliance. Air districts may offer a project life fewer than ten years.
(E) For all agricultural equipment projects refer to FARMER guidelines.
3. Usage
Cost-effectiveness calculations must be based on hours operated. Alternative usage methods including miles traveled or fuel consumed may be used with an approved Case-By-Case determination (CBC). Air districts shall calculate hours of usage based on one of the following:
(A) Usage documentation is the average of a minimum of 24 months provided by the applicant at the time of application. For example, if an applicant has ten years of usage data, at least the previous 24 months of usage data must be used. When usage documentation is available, annual usage is not required to be specified in the contract consistent with Chapter 3, Section X.6(B)(1). However, at the district’s discretion, usage may be specified in the contract.
(B) If the previous 24 months of documented usage is not available, hours of usage may be estimated based on information provided by the applicant and good engineering judgment. When documented usage is not available, the estimated minimum annual usage is required to be specified in the contract consistent with 6/11/2026 5-4 OFF-ROAD EQUIPMENT
Chapter 3, Section X.6.(B)(2). Fleet averages cannot be used to determine estimated usage.
(C) All replacement project engines or equipment must have a fully operational hour meter for the project life. If during the project life the hour meter fails for any reason, it must be repaired or replaced as soon as possible at the owner’s expense.
(D) For zero-emission replacement engines or equipment, usage readings may be per an hour meter or other appropriate metric per, Chapter 3, Section X.7, pending approval by CARB.
D. Project Criteria
The minimum qualifications for off-road projects are listed below. All projects must also conform to the requirements in Chapter 2: General Criteria and in Chapter 3: Program Administration. Participating air districts retain the authority to impose additional requirements in order to address local concerns.
1. General Criteria
(A) Existing engines or equipment replaced with new or cleaner engines or equipment, including ZE equipment, are eligible for funding. (B) Air districts have discretion to use good engineering judgment to determine project horsepower for an existing or new engine or equipment based on the engine label, manual, engine records, or other verifiable records that can be requested from the manufacturer.
(C) For existing equipment in which the actual engine horsepower cannot be determined based upon the engine label, manual, and engine records, air districts may determine existing engine horsepower by the following formula:
Engine horsepower = Power Take Off (PTO) x 120 percent. (D) Future annual hours of equipment operation for determining emission reductions must be based upon readings from an installed and fully operational hour meter.
For the purpose of determining usage to calculate emission reductions, the future hours of replacement equipment operation may be estimated using the procedures outlined in the Usage section found in paragraph C.3 of this chapter.
For the purpose of reporting actual usage of the replacement equipment during the project life, annual hours of equipment operation during the project life must be based upon readings from an installed and fully operational hour meter. (E) The certification emission standard and/or Tier designation for the baseline engine (if applicable) and the new engine should be determined from the CARB Executive Order which can be found at: New Vehicle and Engine Certification:
Executive Orders or the U.S. EPA Annual Certification Data for Vehicles, Engines, and Equipment website which can be found at: New Vehicle and Engine Certification: Executive Orders. If further clarification is needed, refer to the Tier Off-Road Diesel Color Regulation Chart.
(F) For existing equipment with engines manufactured under the flexibility provision, detailed in CCR, title 13, Section 2423(d), the baseline emission rates shall be 6/11/2026 5-5 OFF-ROAD EQUIPMENT
determined by using the previous applicable Tier emission standard for the existing engine model year and horsepower rating. Alternatively, the baseline emission rates may be determined based upon the standard or Tier associated with the actual reference family listed on the emission control information label of the existing equipment. The CARB Executive Order for these engines indicates that the engines are certified under the flexibility provision. Air districts must retain this documentation in the project file.
(G) Baseline engines that participated in the “Tier 4 Early Introduction Incentive for Engine Manufacturers” program, as detailed in CCR, title 13, Section 2423(b)(6), are eligible for funding provided that they are certified to the Tier 4 Final emission standards. CARB’s Executive Order for these engines indicates that the engines are certified under this provision. The emission rates for these engines used to determine cost-effectiveness shall be equivalent to the emission factors associated with Tier 3 engines. Air districts must retain this documentation in the project file.
(H) New engines certified to the interim Tier 4 (interim Tier 4, Tier 4 Phase-Out, Tier 4 Phase-in/Alternate NOx) and Tier 4 Final emission standards participating in the averaging, banking, and trading program that are certified to FEL higher than the applicable emission standards are not eligible for funding. (I) New engines certified to the Tier 4 Final emission standard participating in the averaging, banking, and trading program that are certified to a FEL below the applicable emission standards are eligible for funding. The appropriate emission factor for calculating emission reductions and cost-effectiveness shall be the emission factor associated with the Tier 4 Final or cleaner emission standard. (J) New engines eligible for off-road projects must meet the Tier 4 Final or cleaner emission standard.
(K) Existing zero- or low-emission equipment are required for worker safety in the following industries, and therefore these projects are not eligible for funding:
food retail stores, cold storage, and confined space operations (such as freezers). (L) The horsepower rating for the replacement engine must not be greater than a 35 percent increase of the original manufacturer rated horsepower of the existing baseline engine (baseline horsepower). For example, the 35 percent increase of 100hp is 135hp. Horsepower ratings up to a 35 percent increase of the baseline horsepower are considered to be in the allowable horsepower range.
Example 1: 135% of the horsepower of a 100 hp engine is the range 100 hp to 135 hp. The horsepower range of 100 hp to 235hp would be incorrect. (M) The air district may approve a greater than 35 percent increase in horsepower under any of the following circumstances:
(1) Equipment in the allowable horsepower range is not available. (2) The higher horsepower equipment will result in equal or lower annual emissions than equipment in the allowable horsepower range. (3) The replacement equipment is zero-emission.
(4) In cases where section (M)(1) through (M)(3) do not apply, if the replacement 6/11/2026 5-6 OFF-ROAD EQUIPMENT
engine may be greater than a 35 percent increase, the applicant will pay the additional costs associated with the higher horsepower engine. In this circumstance, the emission reduction calculation must be based upon the funded (higher horsepower) engine.
(5) If the replacement engine is greater than a 35 percent increase, the eligible funding amount must be based upon the cost of an engine or equipment whose horsepower is within the allowable horsepower range. The air district’s project file must include documentation of the cost of the higher horsepower equipment as well as the method used to determine the basis for the project grant amount (e.g., dealership cost estimate of lower horsepower equipment). (N) No funds will be issued for maintenance or repairs related to the operation of the existing or new equipment. The participant takes sole responsibility for ensuring that the engine and/or equipment is/are in operational condition throughout the agreement period.
(O) Existing engines replaced as part of an off-road project must be destroyed and rendered useless. At a minimum, the destruction of an engine must include:
(1) A hole in the engine block with a diameter of at least three inches at the narrowest point. The hole must be irregularly shaped (i.e., no symmetrical squares or circles) and
(2) A section of the oil pan flange must be removed as part of the hole or have a line cut through it that connects the hole.
(3) At the district’s discretion, an alternative method of destruction may be used so long as the engine is destroyed and rendered inoperable and the method is consistent with the air district’s Policies & Procedures per Chapter 3, Section AA.4.
(P) For portable/stationary agricultural projects, refer to the requirements detailed in the FARMER Guidelines for eligibility. FARMER Guidelines can be found through:
Funding Agricultural Replacement Measures for Emission Reductions (FARMER) Program Guidelines. Non-agricultural portable/stationary equipment are eligible for funding through the Moyer Program as long as they are surplus to local rules.
Per California Assembly Bill (AB) 1317 (Gray, Chapter 634, 2017), covered sources include stationary irrigation or water conveyance engines (H&SC Section 44275(a)(7). These sources are limited to non- agricultural use engines. These engines may be used, for example, in conservation or fire extinguishing. Eligible non-agricultural stationary projects may also include water conveyance engines or stationary irrigation engines.
(Q) For baseline emission reduction calculations, the emission factors used from Appendix D will reflect the executive order of the engine model. Baseline engines with no emission control devices will follow the applicable uncontrolled emission standards for the given year. Only eligible baseline engines per the applicable regulation will be considered for emission reduction calculations.
2. Repower
(A) New engines manufactured under the “Flexibility Provisions for Equipment 6/11/2026 5-7 OFF-ROAD EQUIPMENT
Manufacturers” as detailed in CCR, title 13, Section 2423(d), are ineligible for funding to repower equipment.
(B) New engines manufactured under the “replacement engine” provisions of CCR, title 13, Section 2423(j) and/or the provisions of 40 Code of Federal Regulations (CFR) 1068.240 which are used to repower equipment to the Tier 4 Final, or cleaner emission standard, or zero-emission are eligible for funding.

E. Zero-Emission Utility Terrain Vehicle (UTV) Voucher Projects
1. Guidance
This section describes the minimum criteria and requirements for the Zero-Emission Utility Terrain Vehicle (UTV) Voucher Projects (UTV replacement project). The UTV voucher projects are intended to encourage and accelerate the use of off-road, zeroemission UTVs to qualified public agencies, nonprofit agencies, and business 6/11/2026 5-16 OFF-ROAD EQUIPMENT
operations by providing vouchers for the purchase of new zero-emission UTV vehicles. UTV replacement provides a streamlined approach to reduce emissions from certain smaller off-road engines by replacing baseline combustion UTVs with zero-emission UTVs. UTVs are not required to be replaced by Off-Highway Recreational Vehicle CARB Program, making the emission benefits surplus. The UTV replacement project provides funding for vouchers to offset part of the cost of a replacement zero-emission UTV. The UTV Replacement Project would provide incentives for up to 75 percent of the cost of a new zero-emission UTV with a maximum of $13,500 to qualified businesses, public agencies and entities, and nonprofit organizations involved in commercial operations.
2. Determining Funding Amounts
(A) Projects Eligible for Funding:
The purchase of new zero-emission UTV to replace the baseline combustion UTV that is to be scrapped is eligible for funding under this project. (B) Maximum Eligible Funding Amounts
