Environmental Quality Incentives Program 

Conservation Innovation Grants (b) 

Agricultural Emissions Reductions 

Guidelines, Policies, and Procedures 

April 2009 

The USDA Natural Resources Conservation Service (NRCS) is assisting agricultural 

producers with reducing ozone precursors [oxides of Nitrogen (NOx) and Volatile 

Organic Compounds (VOC)] and particulate matter [respirable (PM10) and fine (PM2.5)] 

emissions from agricultural sources through innovative air quality practices. The 

assistance offered through the NRCS encourages agricultural producers to use new 

and innovative agricultural emission reduction practices and technologies that provide 

significant environmental benefits to our natural resources. The primary goal is to 

achieve and maintain the National Ambient Air Quality Standards (NAAQS) in 

designated nonattainment areas in California.

Funding for this initiative is provided through the Environmental Quality Incentives 

Program (EQIP) Conservation Innovation Grants (b) [CIG (b)] portion of the 2008 USDA 

Farm Bill. The NRCS is providing payments for participants to implement conservation 

practices on their lands that benefit air quality. The priority is to improve existing, high 

polluting combustion systems and implement conservation practices that together result 

in reducing emissions. 

Conservation practices that reduce ozone precursors and particulate matter include, 

but are not limited to: 

Chipping Annual Almond and Walnut Pruning, and Chipping Orchard and Vineyard 

Removals (Code 384) 

Combustion System Air Emissions Management (Code 723) 

Conservation Tillage Residue Management (Codes 329 & 345) 

Dust Control on Unpaved Farm Roads and Equipment Yards (Code 729) 

Pest Management (Code 595) 

Precision Pest Control Application (Code 718) 

Treated Wood Stake Disposal (Code 500) 

Waste Utilization – Manure Injection (Code 633) 

Windbreak/Shelterbelt Establishment at Confined Animal Facilities (Code 380) 

This initiative provides payments associated with the expense of implementing new and 

innovative air quality technologies and practices. Payments are available for eligible 

practices that meet the specific program criteria. The applications that provide the 

greatest environmental benefit will be ranked highest in awarded funding through an 

evaluation process that is based on total emission reductions. 

Participants must first obtain NRCS approval prior to the purchase and installation of 

any technology, system, or practice. Final approval is through a Form CCC-1202

 Chipping Annual Almond and Walnut Pruning 

Chipping Removed Orchards and Vineyards 

Forest Slash Treatment 

(Code 384) 

Emission reductions are achieved by chipping agricultural crop residue from orchards 

instead of burning them. The combustion process from open burning can emit 

significant amounts of particulate matter (PM10 and PM2.5), ozone precursors (NOx 

and VOC) and carbon monoxide emissions. Open burning may only occur on 

“permissive burn days” or days when a burn allocation is available. In addition, open 

burning is being or has been phased out in some areas of California due to air quality 

nonattainment concerns.

Chipping pruning from almonds or walnut orchards is eligible for payments provided that 

the orchards have not been chipped in prior years. Payments are allowed on almond 

and walnut orchards that are at the fourth leaf stage or older. 

Chipping removed orchards of any type or vineyards are eligible for payments. 

Orchards that have had tree tops cut off for use as firewood are not eligible. 

Wood chips may be used by leaving them in the orchard to decompose, hauled to a 

biomass-powered electric generation plant for use as fuel, composting, or placed on an 

unpaved road or surface to control fugitive dust.

Combustion Systems Air Emissions Management 

(Code 723) 

Emission reductions are achieved by improving an existing high polluting combustion 

system. This category can provide real emission reduction benefits by retiring the high 

polluting equipment earlier than through normal attrition. 

In 1998, the California Air Resources Board identified diesel particulate matter as a toxic 

air contaminant. Exposure to diesel emissions may result in negative health affects.

Diesel emissions also include oxides of Nitrogen (NOx), a precursor to ozone in smog 

formation that has also been shown to cause adverse health affects. Cost-effective 

measures for reducing the toxic air contaminants and NOx emissions can be achieve 

with early replacement of older agricultural equipment. 

Eligible Projects: Eligible projects involve replacing a high polluting, fully functional 

engine with newer reduced-emission engine meeting the most current model year 

California emissions standards.

Payments are available to replace an existing engine (engine repower) with a newer 

emissions certified engine instead of rebuilding the existing engine to its original 

specifications. The replaced equipment must perform a similar function as the old 

equipment. 

Replacing an engine, however, may not always result in the best value. Replacing only 

the engine on equipment may not be possible due to design constraints or the 

diminished value of the old equipment may not justify investing significant funds for 

engine replacement. These situations will be evaluated on a case-by-case basis. If 

approved, payments will be made for the reductions achieved from equipment replaced 

with new emissions technology.

If repowering with an engine meeting the current applicable emission standard is 

technically unfeasible, unsafe, or cost-prohibitive to develop at the time funds are 

obligated, then the engine must meet the most current practicable, previously applicable 

emission standard. The participant must submit a written statement of reason provided 

by the engine manufacturer verifying that a particular piece of equipment cannot 

accommodate an engine meeting current specifications without major modifications, 

safety risks, exorbitant costs, or for which engine or equipment models for repowers are 

not available or feasible. 

The replacement engine and equipment must be certified for sale in California and meet 

the most recent model year emission standards and/or emissions standards established 

by the local APCD or AQMD, if applicable. Once in operation, the engine and 

equipment must be used exclusively in California.

Significant air quality benefits can result if two or more engines are replaced with a 

single engine performing similar duties. Eligibility will be evaluated on a case-by-case 

basis by examining the estimated emission reductions and cost effectiveness. 

The upgrading or installation of fueling stations and infrastructure is not eligible, 

including the expense of installing fuel storage tanks, construction of fueling depots, or 

construction of biodiesel manufacturing facilities. 

Retrofits to an engine may be eligible. A retrofit is the installation of an emission control 

system verified by the ARB, such as diesel particulate filters, diesel oxidation catalysts, 

or selective catalyst reduction systems. Retrofit technology may be installed on an 

existing engine that results in meeting current emission standards or on a new engine 

that results in additional emission reductions. 

1. For an uncontrolled diesel engine, the retrofit kit must be verified to reduce NOx 

or NOx+NMHC (non-methane hydrocarbons) emissions to the applicable current 

Tier standard for a given engine type and size. 

2. For an uncontrolled spark-ignited engine, the retrofit kit must be verified to 

reduce NOx+NMHC emissions to the currently applicable standards for sparkignited engines. 

3. For an emission-certified (1996+ model year) diesel engine, the retrofit kit must 

be verified to reduce NOx or NOx+NMHC emissions by at least 15% from the 

applicable NOx or NOx+NMHC emission standard. 

4. The retrofit kit to reduce PM must use the highest level ARB-verified technology 

available for the engine being retrofitted.

A complete list of ARB-verified retrofits may be found via the Internet at: 

http://www.arb.ca.gov/diesel/verdev/verdev.htm.

Ownership: The existing engine or equipment being replaced must be owned by the 

participant, have been used in the State of California for at least 12 months prior to the 

application submittal date, have some remaining life, and will be destroyed.

Destruction: Soon after being replaced, the old, existing engine and equipment (if 

applicable) must be destroyed. Destruction of the old engine and equipment 

permanently removes the existing, high emitting equipment from service and ensures 

that the emission reductions are real. It also prevents the existing equipment from 

being moved into another locale to continue emitting high levels of pollutants. The 

participant must therefore certify that the old equipment has been destroyed and 

rendered useless. 

Contract Duration: A minimum two-year contract period is required. The participant 

must initiate the project within the first year of the contract. Payment is initiated once all 

contract obligations are met.

(Code 723) 

Section 1 

Stationary Heavy-Duty Engines 

This category primarily refers to stationary (i.e. bolted to a foundation or concrete slab) 

or portable (i.e. mounted on a trailer or skid, but does not drive a vehicle) engines, and 

may include auxiliary engines on mobile equipment provided that the auxiliary engine 

does not propel a vehicle. The majority of these engines are used for irrigation. 

The California Air Resource Board (ARB) established emission standards and 

requirements that regulate the sale, purchase, rental, lease, and operation of diesel 

engines, including stationary and portable equipment used exclusively in agriculture. In 

addition, an Air Pollution Control District (APCD) or Air Quality Management District 

(AQMD) may impose emission standards through a rule or require permits with 

emission limits that may be more restrictive than required by the ARB. The participant 

should first consult with the local APCD or AQMD to determine permitting and 

emissions requirements prior to seeking assistance from the NRCS. 

Program Requirements 

Existing equipment: 

A) The existing engine must be uncontrolled or certified to an early Tier level. 

B) Rated at 50 or more maximum brake horsepower (37 or more kilowatts).

C) The participant must own and operate the equipment in California for at least the 

past 12 months. 

D) The existing equipment is situated at its operation location and be in operational 

condition to qualify. 

Replacement equipment: 

A) The new replacement engine and equipment must be certified for sale in 

California and meet the most recent model year emission standards and/or 

emissions standards established by the local APCD or AQMD, if applicable. 

Once in operation, the engine and equipment must be used exclusively in 

California.

B) California Air Resources Board Executive Orders for certified off-road diesel 

engines are posted on the Internet at

Page 31 

C) Spark-ignited engines must meet or exceed the applicable emission standards 

established by the ARB or local APCD or AQMD.

D) Replacing an engine with an electric motor rated at 50 hp (37 kilowatts) or more 

is eligible. 

E) The horsepower rating of the replacement equipment engine must be within 25% 

of the original manufacturer rated horsepower (baseline) for the old equipment 

engine. This may be waived if the original horsepower range is not available. 

F) The replacement engine must show at least a 15% NOx reduction and no 

increase in particulate matter emissions, compared with the applicable standards 

or emission levels for that engine year and type of application through ARB 

Certification Testing, USEPA Certification Testing, or emissions testing at a 

laboratory approved by the USEPA or ARB. 

G) Have an approved Authority to Construct from the local APCD or AQMD prior to 

application, if a permit is required. 

H) An APCD or AQMD may require an emissions source test on the new engine, 

depending on the conditions specified on an applicable Authority to Construct or 

Permit to Operate. Source testing using accepted testing protocols must be 

completed by an ARB-certified independent contractor to the satisfaction of the 

APCD or AQMD before payments will be provided. A list of approved 

independent contractors is posted on the Internet at 

http://www.arb.ca.gov/ba/icp/current.pdf

I) The participant is advised to maintain a record of new equipment usage for at 

least the first five years of operation. Hours of operation may be accomplished 

by recording the readings from a fully operational hour meter at the beginning 

and end of each year.

Existing Equipment Destruction

The old, existing engine must be destroyed. Destruction of the engine permanently 

removes the existing, high emitting equipment from service and ensures that the 

emission reductions are real. It also prevents the existing equipment from being moved 

into another locale to continue emitting high levels of pollutants. 

A) The existing engine may be rendered inoperable and destroyed by following 

methods:

(1) Punching a hole not smaller than four inches in diameter through the 

engine block, or 

(2) Crushing or scrapping the engine at a salvage yard. 
EQIP - Agricultural Emissions Reductions

following minimum standards: 

A) For an uncontrolled diesel engine, the retrofit kit that must be verified to reduce 

NOx or NOx+NMHC (non-methane hydrocarbons) emissions to the applicable 

current Tier standard for a given engine type and size. 

B) For an uncontrolled spark-ignited engine, the retrofit kit must be verified to 

reduce NOx+NMHC emissions to the currently applicable standards for sparkignited engines. 

C) For an emission-certified (1996+ model year) diesel engine, the retrofit kit must 

be verified to reduce NOx or NOx+NMHC emissions by at least 15% from the 

applicable NOx or NOx+NMHC emission standard. 

D) The retrofit kit to reduce PM must use the highest level ARB-verified technology 

available for the engine being retrofitted.

Conservation Tillage Residue Management 

Residue and Tillage Management, No-Till, Strip Till 

(Code 329) 

Residue and Tillage Management, Mulch Till 

(Code 345) 

The adoption of on-field conservation tillage practices that increase the amount of crop 

residue left on the soil surface and/or reduce the number of tillage operations used to 

raise the crop. Emission reductions are associated with reducing soil disturbances and 

leaving crop residue on the soil surface, thus emitting less particulate emissions.

Conservation tillage also has an added benefit of reducing the number of vehicle trips, 

which results in less fuel consumption and reduced emissions from combustion 

equipment. 

All annually tilled row crops are eligible for payments. Participants are encouraged to 

disturb less than 100 percent of the soil surface and leave more crop residue on the soil 

surface.

Dust Control on Unpaved Farm Roads and Equipment Yards 

(Code 729) 

Fugitive dust generated from unpaved roads and traffic areas can become significant 

sources of particulate matter emissions (PM10 and PM2.5). The best practice for 

limiting fugitive dust is to stabilize the unpaved surface by treating with a dust palliative. 

Many dust palliatives are effective with limiting fugitive dust, including the application of 

water, road salts, lignin-based products, and emulsifiers. However, the dust control 

technology eligible for payments is the single application of SC 250 heavy road oil or 

equivalent product. This practice will result in at least 50% control of PM10 emissions 

from treated surfaces for up to two years after application. More permanent treatments 

will achieve this control efficiency over a five year period. 

Certain eligibility conditions apply: 

A one-time application of SC 250. Use SC 800 on alkali soils. 

The unpaved surface should be graded, removing any potholes and imperfections. 

If possible, incorporate a crown. 

Roadbed should be moistened to facilitate oil penetration. 

Restrict traffic on the surface until the oil has cured. A light coating of sand may be 

applied if shiny spots remain after seven to ten days after application. 

Application rate is 3,000 gallons per mile based on a 10-foot wide swath. 

A more permanent treatment design must be pre-approved by the NRCS. In addition to 

the above conditions the following minimum conditions apply for multi-year projects: 

A one-time application of SB 250. Use SC 800 on alkali soils. 

Install at least a 2 inch road base. The accepted base materials include ground 

asphalt, or standard road base or crushed granite meeting Class II 3⁄4 inch 

standards.

The treated surface must be maintained. Potholes, ruts, implement damage or other 

destabilizing abrasions must be corrected. Dust deposited on roads from 

agricultural traffic, implements, and wind must be periodically removed from the 

surface. The road must remain reasonably free of mud and dirt track-out and carryout. The road must be otherwise maintained in travelable condition.

Pest Management 

(Code 595) 

Where properly implemented, Integrated Pest Management (IPM) systems can result in 

substantially lower use of pesticides capable of impacting resource concerns such as air 

quality, water quality, and human health. These comprehensive pest management 

systems are used to manage pest populations at or below economically tolerable levels 

using many tactics, such as encouraging beneficial insects, researched and 

scientifically designed monitoring systems, improved understanding of pest lifecycles 

that provide a basis for alternative lower risk control measures, integration of low impact 

chemicals to reduce pest populations, pheromones to disrupt mating, among others. 

To meet air quality objectives, producers must reduce the use of high VOC containing 

materials as designated by California Department of Pesticide Regulation. In addition, 

producers will be required to follow IPM programs prepared by the University of 

California Integrated Pest Management Program (UC IPM) as described on the UC IPM 

website (http://www.ipm.ucdavis.edu).

The Year Round Level 1 practice is for producers growing crops with published Year 

Round IPM programs available on the UC IPM website. These programs, as modified 

in consultation with local UCCE IPM experts to fit local conditions, must be implemented 

in their entirety by the producer.

The Reduced VOC Level 1 practice requires the producer to implement an entire 

IPM program for one major insect pest as described in the appropriate Pest 

Management Guideline found on the UCIPM website and to reduce the number of 

high VOC emitting materials on the field. From the baseline established in Pesticide 

Use Reports submitted with the application, the participant must reduce one 

application for a payment in year one, reduce two applications in year two, and 

reduce three applications in year three. 

The Reduced VOC Level 2 practice requires following the Level 1 practice and 

adding a pre-authorized high cost IPM practice found in the UCIPM Pest 

Management Guidelines for the crop and pest of concern.

The UC IPM Year-Round Program with reduced VOC-Level 1 requires the 

participant to follow the year round IPM program for a specified crop and to reduce 

the application of high VOC emitting materials as described above. 

The UC IPM Year-Round Program with reduced VOC-Level 2 requires the same 

practices as Level 1 with a pre-authorized high cost IPM practice found in the UC 

IPM Pest Management Guidelines for the crop and pest of concern.

Detailed instructions for field implementation are available.

Precision Pest Control Application 

(Code 718) 

The California Department of Pesticide Regulation (DPR) has targeted a minimum of 20 

percent reduction in volatile organic compound (VOC) emissions from agricultural 

pesticide usage by year 2010. To reduce VOC emissions from agricultural pesticide 

usage, assistance is available to agricultural producers who plan to adopt new precision 

pesticide spray application technologies that address site specific management of 

variable pest populations. 

Eligible technologies have peer-reviewed research documentation of the VOC reducing 

capabilities of the technology. Priority is given to optical sensor sprayers and Sonar 

sensing technology products documented with providing at least a 20 percent reduction 

in VOC emissions (excludes mechanical tillage equipment). 

To be eligible, the following documentation is required: 

Pesticide use reports on enrolled acres for the previous two years. 

Current equipment being used (i.e. photographs, invoices for services provided, and 

signed statement of usage) 

Long term commitment to equipment usage. 

Ineligible projects include: non-ID targeting applicators, spray nozzle technologies, 

electro-static spray technologies, open flame desiccation, other non-smart sprayer 

technologies, or precision spray technologies already being utilized on the property. 

Another eligible precision treatment applies to fields treated with soil fumigants and post 

water applications to limit VOC emissions. Sprinklers are used to apply three water 

applications of at least 0.2 inches each at specified times after fumigation is completed 

according to DPR regulations. Two payment schedules apply to this practice: 

(1) Use sprinklers for stand establishment and/or seasonal irrigations (with in-season 

sprinkler use). 

(2) Fields irrigated with sprinklers for no other reason than to manage VOC 

emissions (without in-season sprinkler use).

Treated Wooden Stake Disposal 

Obstruction Removal 

(Code 500) 

This program is designed to assist agricultural producers with the proper disposal of 

chemically treated wooden stakes. This wood is typically treated with preserving 

chemicals that protect the wood from insect attack and fungal decay during its use. 

These chemicals can pose a risk to human health and the environment. Chemicals 

added to preserve wood and known to be toxic or carcinogenic include arsenic, 

chromium, copper, creosote, and pentachlorophenol. Harmful exposure may be by 

direct contact with the skin or by inhalation or ingestion of the particulate through smoke 

from open burning or sawdust from cutting or chipping the wood.

The majority of chemically treated wood stakes used in agriculture are treated with 

Chromium Copper Arsenate (CCA). As a result, all CCA-treated wood products used 

as support structures for crops are eligible for payments, regardless of crop type. The 

priority is given to existing piles of stakes and to agricultural producers that have 

switched to other materials for support systems. With limited resources available, the 

intent is to remove the threat of accidental combustion and reduce the potential damage 

to underground and surface waterways.

Payments are available one-time per location and consider the loading, transportation, 

and proper disposal of CCA-treated stakes. Payments are on a per acre basis, 

equating to 1.5 tons of stakes per acre, up to 310 tons of stakes. 

The California Department of Toxic Substance Control (DTSC) requires that chemically 

treated wood be disposed of in an approved landfill. In addition, any agricultural 

producer generating more than 10,000 pounds of chemically treated wood in a calendar 

year must obtain an identification number and notify the DTSC within 30 days of 

exceeding this limit. More information on storage, transportation, and disposal of 

chemically treated wood is posted on the DTSC website at 

http://www.dtsc.ca.gov/HazardousWaste/Treated_Wood_Waste.cfm.

Landfills that accept CCA-treated wood can be found at

Manure Injection 

Waste Utilization 

(Code 633) 

Current research has identified dairies as a source of volatile organic compounds (VOC) 

emissions, an ozone precursor. A source of VOC emissions is from the land application 

of dairy manure onto the soil surface. Through effective land application of manure by 

injection into the soil, substantial reductions of VOC emissions can be achieved. 

Assistance is available for reducing VOC emissions by implementing the practice of 

injecting manure directly into the soil provided this practice is coordinated under a 

nutrient management plan. 

To be eligible, the following conditions must be met: 

Complete soil tests reporting the residual nitrogen, phosphorous, and potassium salt 

levels

Crop yield goals 

Manure nutrient tests 

Appropriate application rates and timing of manure to match crop needs 

Accounting of nutrient supply from all sources 

Direct injection of manure into the soil 

Payment assistance is not available for nutrient management practices already being 

performed on a dairy, including irrigation water run of manure with or without 

incorporation, broadcast manure on the soil surface with incorporation by disking, 

injection manure without preparation, or following the conditions specified in a nutrient 

management plan.

Windbreak/Shelterbelt Establishment around 

Confined Animal Facilities 

Windbreak/Shelterbelt Establishment 

(Code 380) 

Research has indicated that confined animal facilities (CAF) are sources of PM10 and 

volatile organic compounds (VOC) emissions created through animal production 

activities and the waste they generate. Emission reductions are achieved as 

windbreaks can reduce emissions into the atmosphere by intercepting the particulate 

matter and containing them within the trees. Established windbreaks can obtain 22.5% 

PM10 control efficiency. As an added benefit, odors leaving a CAF are reduced in 

areas downwind if a windbreak has been established. 

Participants may achieve PM10 emission reductions when establishing a 

windbreak/shelterbelt around the CAF. To be eligible for payments, participants must 

establish a one, two, or three or more row windbreak. An irrigation system properly 

designed must be installed for new windbreak plantings according to NRCS 

Conservation Practice Standard 441 (Irrigation System, Microirrigation) or 442 (Irrigation 

System, Sprinklers).

Combustion Systems Air Emissions Management

(Code 723)

Emission reductions are achieved by improving existing high polluting combustion 

systems. This category can provide real emission reduction benefits by retiring the high 

polluting equipment earlier than through normal attrition and replacing with new, cleaner 

technology.

In 1998, the California Air Resources Board identified diesel particulate matter as a toxic 

air contaminant. Exposure to diesel emissions may result in negative health affects. 

Diesel emissions also include oxides of Nitrogen (NOx), a precursor to ozone in smog 

formation that has also been shown to cause adverse health affects. Cost-effective 

measures for reducing the toxic air contaminants and NOx emissions can be achieve 

with early replacement of older agricultural equipment.

Eligible Projects

Replacing high polluting, fully functional engines with newer reduced-emission engines 

meeting the most current model year California emissions standards. 

Payments are available to replace an existing engine (engine repower) with a newer 

emissions certified engine instead of rebuilding the existing engine to its original 

specifications. The replaced equipment must perform a similar function as the old 

equipment. 

Replacing an engine, however, may not always result in the best value. Replacing only 

the engine on equipment may not be possible due to design constraints or the 

diminished value of the old equipment may not justify investing significant funds for 

engine replacement. These situations will be evaluated on a case-by-case basis. If 

approved, payments will be made for the reductions achieved from equipment replaced

with new emissions technology.

If repowering with an engine meeting the current applicable emission standard is 

technically unfeasible, unsafe, or cost-prohibitive to develop at the time funds are 

obligated, then the engine must meet the most current practicable, previously applicable 

emission standard. The participant must submit a written statement of reason provided 

by the engine manufacturer verifying that a particular piece of equipment cannot 

accommodate an engine meeting current specifications without major modifications, 

safety risks, exorbitant costs, or for which engine or equipment models for repowers are 

not available or feasible.

The replacement engine and equipment must be certified for sale in California and meet 

the most recent model year emission standards and/or emissions standards established 

by the local APCD or AQMD, if applicable. Once in operation, the engine and 

equipment must be used exclusively in California.

Significant air quality benefits can result if two or more engines are replaced with a 

single engine performing similar duties. Eligibility will be evaluated on a case-by-case 

basis by examining the estimated emission reductions and cost effectiveness.

The upgrading or installation of fueling stations and infrastructure is not eligible, 

including the expense of installing fuel storage tanks, construction of fueling depots, or 

construction of biodiesel manufacturing facilities.

Retrofits to an engine are eligible. A retrofit is the installation of an emission control 

system verified by the ARB, such as diesel particulate filters, diesel oxidation catalysts, 

or selective catalyst reduction systems. Retrofit technology may be installed on an 

existing engine that results in meeting current emission standards or on a new engine 

that results in additional emission reductions. 

The existing engine or equipment being replaced must be owned by the participant, 

have been used in the State of California for at least 12 months prior to the application 

submittal date, have some remaining life, and must be destroyed. 

Soon after being replaced, the old, existing engine and equipment (if applicable) must 

be destroyed. Destruction of the old engine and equipment permanently removes the 

existing, high emitting equipment from service and ensures that the emission reductions 

are real. It also prevents the existing equipment from being moved into another locale 

to continue emitting high levels of pollutants. The participant must therefore certify that 

the old equipment has been destroyed and rendered useless.

NRCS payments schedules are available and vary depending on the type and size of 

the new engine or equipment.

A minimum two-year contract period is required. The participant must initiate the project 

within the first year of the contract. Payment is initiated once all contract obligations are 

met.

Section 1: Definitions

Add-On Control Device: an air pollution control device, such as catalytic converter, 

that reduces the pollution in exhaust gas. The control device usually does not affect 

the process being controlled and thus is "add-on" technology, as opposed to a 

scheme to control pollution through altering the basic process itself.

Ambient Air Quality Standards (AAQS): National and State health- and welfarebased standards for outdoor air, which identify the maximum acceptable average 

concentrations of air pollutants during a specified period of time. A chart of the 

national and state AAQS is posted on-line at: 

www.arb.ca.gov/research/aaqs/aaqs2.pdf.

ARB: the State of California Air Resources Board.

Brake Horsepower (bhp): the measure of an engine's horsepower without the loss in 

power caused by the gearbox, generator, differential, water pump, and other 

auxiliary components that may slow down the actual speed of the engine. For 

Practice Code 723, the engine horsepower determination is based on the Rated 

Brake Horsepower.

Certified Compression-Ignited Engine: a Tier 1, Tier 2, Tier 3, or Tier 4 compressionignited engine certified by the EPA and/or the ARB. Tier schedule is on Table 1.

Certified Spark-Ignited Engine: a spark-ignited engine that is ARB-certified as 

specified in Title 13, Division 3, Chapter 9, Article 4.5, Section 2433 of the California 

Code of Regulations.

Compression-Ignited Internal Combustion Engine: an engine that uses the heat of 

compression to initiate combustion. 

Criteria Air Pollutant: derived from EPA, an air pollutant for which acceptable levels of 

exposure can be determined and an ambient air quality standard has been 

established, based on the pollutant’s characteristics and potential health and welfare 

effects. These pollutants include ozone, carbon monoxide, nitrogen dioxide, sulfur 

dioxide, particulate matter (PM10 and PM2.5), and lead.

Diesel Engine: a compression-ignited internal combustion engine.

Diesel Exhaust Particulate Matter: the ARB designates diesel exhaust particulate 

matter as a toxic air contaminant (TAC) based on its potential to cause cancer, 

premature death, and other health problems. As a result, the ARB established 

several Airborne Toxic Control Measures (ATCM’s) that are codified in the California 

Code of Regulations. The ATCM’s establish emission standards to reduce diesel 

exhaust particulate matter and health risks. Diesel exhaust particulate matter 

ATCM’s are posted on-line at: www.arb.ca.gov/toxics/atcm/atcm.htm.

Drawbar Horsepower: is the power an agricultural tractor has to pull an implement. 

The power is determined by utilizing a special a dynamometer car coupled behind a 

tractor that keeps a continuous record of the drawbar pull exerted and the speed. 

For Practice Code 723, drawbar horsepower will not be used for comparison with 

rated break horsepower because this value varies under different operating 

conditions and does not necessarily correlate with the engine horsepower. 

Emergency Standby Engine: a stationary engine where the primary purpose is to 

provide electrical or mechanical power in an emergency and operate to provide 

electrical power or mechanical work during an emergency use. Limited nonemergency use may occur for maintenance and testing purposes, impending 

outages, or under a Demand Response Program administered by a utility.

Emission Control System: any device or system employed with engines or piece of 

equipment that is intended to reduce emissions. Examples of emission control 

systems include, but are not limited to, closed-loop fuel control systems, three-way 

catalysts, fuel injection systems, and combinations of the above.

Engine Repower: the replacement of an existing engine with a new, emissions certified 

engine instead of rebuilding the existing engine to its original specifications.

EPA: The United States Environmental Protection Agency.

Family Emission Limit (FEL): an emission level declared by the manufacturer for use 

in any averaging, banking and trading program and in lieu of an emission standard 

for certification. It serves as the applicable emission standard for determining 

compliance of any engine within an engine family under 13 California Code of 

Regulations Sections 2423 and 2327. Any ARB Executive Order reporting a FEL 

value exceeding an applicable emission standard is not eligible for NRCS payments.

Forklift: Applicability to this practice standard includes electric Class 1 or 2 rider trucks, 

large spark-ignition engine powered Class 4, 5 or 6 rider trucks, and Class 7 rough 

terrain forklifts as defined by the Industrial Truck Association and Occupational 

Safety and Health Administration (OSHA). Electric Class 3 trucks are not forklifts for 

the purposes of this practice standard.

Gross Horsepower (ghp): for purposes of Practice Code 723, the maximum gross 

horsepower equals the rated break horsepower only if bhp information is not 

available.

Gaseous Fuel: a fuel that is a gas under standard conditions, including but not limited 

to: natural gas, methane, ethane, propane, butane and liquefied petroleum gas 

(LPG).

Independent Source Test Contractor: a program administered by the ARB that 

approves private independent source testing contractors to conduct required 

compliance emissions verification testing. Source operators may select from a list of 

contractors. The ARB does not require that testing contractors be approved prior to 

conducting testing in California; however, approval is required if the contractor 

wishes to conduct source testing for compliance verification. A list of contractors is 

available at: www.arb.ca.gov/ba/icp/current.pdf.

Internal Combustion Engine: any spark- or compression-ignited reciprocating engine.

Lean-Burn Engine: an engine operated with an exhaust stream oxygen concentration 

of four percent by volume or greater. Mechanically, such engines may be equipped 

with turbochargers.

Mobile Source Certification: new motor vehicles and engines must be certified by the 

ARB for emission compliance before they are legal for sale, use, or registration in 

California. Certification is granted annually to individual engine families and valid for 

one model year. Certifications are described through ARB Executive Orders, which 

are posted on-line at: www.arb.ca.gov/msprog/offroad/cert/cert.php

Nonattainment Area: a geographic area identified by the EPA and/or the ARB as not 

meeting either National AAQS and/or California AAQS standards for a given 

pollutant.

Non-Methane Hydrocarbon (NMHC): The sum of all hydrocarbon air pollutants except

methane.

NOx: a general designation pertaining to compounds of nitric oxide (NO), nitrogen 

dioxide (NO2) and other oxides of nitrogen. NOx is typically created during the 

combustion processes and are major contributors to ozone formation and acid 

deposition. NO2 causes adverse health affects, is a criteria air pollutant and a major 

component in smog formation. This designation does not include nitrous oxide 

(N2O), which is designated as a greenhouse gas.

Off-Road Compression-Ignition Equipment: Equipment that cannot be registered 

and driven safely on a road or was not designed to be driven on a road. Newer 

equipment uses engines certified by the ARB to the off-road compression-ignition or 

diesel engine standards. Such equipment is most commonly used in construction, 

mining, agriculture, and cargo handling equipment. These engines do not include 

engines at operating at stationary agricultural pump plants.

Off-Road Spark-Ignited Equipment: equipment that cannot be registered and driven 

safely on-road or was not designed to be driven on-road. Newer equipment uses 

engines certified by the ARB to the off-road spark ignition engine standards. These 

engines may be designed to use gasoline fuel, liquid petroleum gas (LPG), 

compressed natural gas, methanol fuel, or a combination of these.

Ozone: a form of molecular oxygen that consists of three oxygen atoms linked together 

(O3). Ozone in the upper atmosphere occurs naturally and protects life on earth by 

filtering out ultraviolet radiation from the sun. However, ozone at ground level is a 

noxious pollutant that causes numerous adverse health affects, is a criteria pollutant, 

and the major component of smog. Ozone is not emitted directly, but is formed in 

the atmosphere through a complex chemical reaction involving hydrocarbons, oxides 

of nitrogen, and sunlight. Problematic ozone levels occur most frequently on hot 

summer afternoons. 

Ozone Precursors: chemicals involving reactive hydrocarbons and oxides of nitrogen, 

occurring either naturally or as a result of human activities, contribute to the 

formation of ozone.

PM: a general designation pertaining to particulate matter emissions. PM2.5 has an 

aerodynamic diameter equal to or less than 2.5 microns and PM10 has an 

aerodynamic diameter equal to or less than 10 microns as measured by the 

applicable State and Federal reference test methods. Their small size allows them 

to make their way to the air sacs deep within the lungs where they may be 

deposited, resulting in adverse health affects. PM also causes visibility reduction and 

contributes to regional haze.

PTO Horsepower: is the “usable” horsepower measurement at the power take-off 

(PTO) shaft’s output and is the power for tractor attachments. For purposes of 

Practice Code 723, multiply the PTO horsepower value by 1.15 if the rated break 

horsepower or gross horsepower information is not available for an existing engine. 

This value will be used for comparison with the rated brake horsepower of a new, 

replacement engine.

Rated Brake Horsepower: the continuous brake horsepower rating specified for the 

engine by the manufacturer or listed on the nameplate of the unit without regard to 

any de-rating or modification. For Practice Code 723, this value is the basis for 

engine rated horsepower.

Retrofit: the installation of an ARB-verified emission control system on an existing 

engine. Examples include, but are not limited to, diesel particulate filters and catalyst 

systems on spark-ignited engines. Verified technologies for diesel engines are 

posted on-line at: www.arb.ca.gov/diesel/verdev/vt/cvt.htm.

Rebuilt or remanufactured: engines offered by the original engine manufacturer 

(OEM) or by a non-OEM rebuilder who demonstrates to the ARB that the rebuilt 

engine and parts are functionally equivalent from an emissions and durability 

standpoint to the OEM engine and components being replaced.

Reactive Organic Gas (ROG): sometimes referred to as non-methane hydrocarbons 

(NMHC), a photo-chemically reactive chemical gas composed of non-methane 

hydrocarbons that may contribute to ozone formation.

Rich-Burn Engine: an engine operated with an exhaust stream oxygen concentration 

of less than four percent by volume. Mechanically are naturally-aspirated engines.

Rough Terrain Forklift: Class VII forklifts powered by compression-ignition engines

and equipped with pneumatic tires that handle uneven surfaces. Such forklifts

include straight-mast and extended-reach forklifts.

Spark-Ignited Internal Combustion Engine: a liquid or gaseous fueled engine 

designed to ignite its air/fuel mixture by a spark across a spark plug.

Tier 1, Tier 2, Tier 3, and Tier 4 Engines (See Table 1 for the applicable Tier 

schedule):

(1) an EPA-certified compression-ignited engine that meets the Tier 1, Tier 2, or Tier 

3 emission standards of Table 1 on page 56970 of the Final Rule (October 23, 

1998) or the Tier 4 emission standards of Table II.A.2 (Tier 4 NOx and NMHC 

Standards and Schedule) on page 38971 of the Final Rule (June 29, 2004) or 

Table II.A.4 (Tier 4 Standards for Engines Over 750 HP (G/BHP-HR)) on page 

38980 of the Final Rule (June 29, 2004), respectively.

(2) An ARB-certified compression-ignited engine that meets the standards according 

to Title 13, Section 2423(b)(1)(A) and/or Title 40, CFR, Part 89.112(a) of the 

California Code of Regulations. Tier 4 engines that are subject to the interim or 

final after-treatment based Tier 4 emission standards in Title 13, Section 

2423(b)(1)(B) and/or Title 40, Part 1039.101 of the California Code of 

Regulations. This also includes engines certified under the averaging, banking, 

and trading program with respect to the Tier 1, 2, and 3 Family Emission Limits 

(FEL) listed in Title 13, Section 2423(b)(2)(A) and/or Title 40, Part 89.112(d) of 

the California Code of Regulations and to the Tier 4 FEL listed in Title 13 Section 

2423(b)(2)(B) and/or Title 40, Part 1039.101 of the California Code of 

Regulations

Toxic Air Contaminant (TAC): an air pollutant, identified in regulation that may cause 

or contribute to an increase in deaths or in serious illness, or which may pose a 

present or potential hazard to human health. TACs are considered under a different 

regulatory process than that of criteria pollutants.

Uncontrolled Compression-Ignition Engine: also referred to as Tier 0, is any diesel 

engine not meeting any established Tier emission standard. Generally, these are 

engines manufactured:

1999 and earlier: >750 hp

1998 and earlier: 25-49 hp

1997 and earlier: 50-99 hp

1996 and earlier: 100-174 hp

1995 and earlier: 175-750 hp

Volatile Organic Compounds (VOCs): many definitions describe VOCs, but are 

primarily organic, carbon-containing compounds having high enough vapor pressure 

under normal conditions to vaporize into the atmosphere. VOCs defined in a legal or 

regulatory concept are carbon compounds that contribute to the formation of ozone, 

as many VOCs are exempt from regulation. For example, methane is a VOC that 

does not contribute to the formation of ozone, but is designated a greenhouse gas. 

VOCs by themselves may also be classified as toxic air contaminants (TAC’s). 

Other terminology describing the photo-reactivity of VOC includes Non-Methane 

hydrocarbons (NMHC); Reactive Organic Gases (ROG); and Total Organic Gases 

(TOG).

Section 2: Stationary Heavy-Duty Engines

This category primarily refers to stationary (i.e. bolted to a foundation or concrete slab) 

or portable (i.e. mounted on a trailer or skid, but does not drive a vehicle) engines, and 

may include auxiliary engines on mobile equipment provided that the auxiliary engine 

does not propel a vehicle. The majority of these engines are used for crop irrigation.

The California Air Resource Board (ARB) established emission standards and 

requirements that regulate the sale, purchase, rental, lease, and operation of diesel 

engines, including stationary and portable equipment used exclusively in agriculture. In 

addition, an Air Pollution Control District (APCD) or Air Quality Management District 

(AQMD) may impose emission standards through a rule or require permits with 

emission limits that may be more restrictive than required by the ARB. It is 

recommended for the participant to first consult with the local APCD or AQMD to 

determine permitting and emissions requirements prior to seeking assistance from the 

NRCS.

units with one new unit is not intended as a means to increase the horsepower rating 

determination for the new engine or equipment, as any increase in horsepower of the 

new engine is limited to 125% of the baseline horsepower rating of the existing engine. 

The intent is to allow for additional emission reduction benefits by permanently retiring 

additional equipment earlier than through normal attrition, which might improve the final 

ranking scores for application prioritization.

A) The emission benefits are determined by subtracting the annual emissions from 

the new replacement engine from the sum of the annual emissions from all 

subject existing engines.

B) At a minimum, the new equipment must serve the same function and perform 

similar work as one of the existing equipment in order to be eligible. The other 

existing equipment may not necessarily be similar in type and functionality of the 

new equipment. The summed emission reductions (not the summed hp) will be 

used for ranking purposes. Examples include the following:

(1) An existing 92 hp 1979 tractor that operates 500 hours/year is retired for a 

new 105 hp Tier 3 tractor. In addition, a 150 hp 1985 loader that operates 

800 hours/year will be retired. In this example, the 92 hp tractor is used 

as the baseline hp rating (i.e. like for like), limiting the maximum hp rating 

of the new equipment to 115 hp (125% of 92 hp). The NOx emission 

reductions are:

Sum of existing engine emissions = 1.17 tons NOx/yr

1979: 0.43 tons = {(92 hp x 12.09 g/bhp-hr x 500 hrs/yr x 0.70)/907,200}

1985: 0.74 tons = {(150 hp x 10.23 g/bhp-hr x 800 hrs/yr x 0.55)/907,200}

New engine emissions = 0.11 tons NOx/yr

Tier 3: 0.11 tons = {(105 hp x 2.74 g/bhp-hr x 500 hrs/yr x 0.70)/907,200}

Total NOx emission reductions = 1.06 tons/yr (91% NOx reduction)

(2) An existing 152 hp 1981 loader and an existing 125 hp 1975 loader will be 

retired for a new 160 hp Tier 4 Interim loader. In this example, despite 

which equipment is directly replaced with the new, the maximum hp of the 

two like equipment may be used as the baseline hp rating, thus limiting the 

maximum hp rating of the new equipment to 190 hp. As with example 

number one, the new engine emissions will be subtracted from the sum of 

the existing engine emissions to calculate the emission reductions.

C) A single piece of equipment may utilize more than a single engine mounted on 

the unit. Such equipment are equipped with multiple engines that operate 

together to perform a single function or task (i.e. a PTO on a self-propelled 

engine plus an auxiliary engine). The horsepower from each engine may be 

summed to determine the overall existing horsepower baseline and the emission 

reductions. However, hours of operations for each engine may not be summed

since multiple engines generally work together. The total emissions calculated 

from each engine may be summed. The maximum horsepower ratings for the 

new replacement equipment shall not exceed 125% of the summed horsepower 

of the existing equipment.

D) All existing engines and equipment used to achieve the additional emission 

benefits must be destroyed.

Existing Equipment Destruction

Engine and equipment destruction must be performed in a safe manner.

Personal Safety always comes first.

A) Soon after being repowered, the existing engine shall be destroyed. 

(1) At a minimum, the existing engine shall be rendered inoperable by 

punching a hole not smaller than four inches in diameter through the 

engine block. 

Additional methods may be employed to destroy an engine, including but 

not limited to compromising the water jacket castings and cutting engine 

heads in half. 

(2) Crushing or scrapping at a salvage yard.

B) Soon after being replaced, the existing engine and equipment shall be destroyed.

(1) Punching a hole not smaller than four inches in diameter through the 

engine block and compromising the structural integrity of the equipment by 

cutting the structural components or frame rails.

Additional methods may be employed to destroy an engine and 

associated drive-train components, including but not limited to 

compromising water jacket castings, cutting engine heads in half, 

punching holes in the transmission casing, and destroying axles.

(2) Scrapping the equipment at a salvage yard.

(3) To avoid any additional resource concerns, the destroyed engine should 

be removed from the property and property disposed. Engine and 

equipment parts should be disposed with the destroyed engine to avoid 

any recycling or reusing of parts.

C) The participant must certify that the existing equipment has been destroyed and 

rendered useless.

(1) The certification must describe the location where the destroyed engine is 

located or where it was scrapped, the engine make and serial number, 

how the engine was destroyed, and the date the engine was destroyed. 

For off-road mobile agricultural equipment destruction, also include the 

make, model, year, and equipment serial number. Photographs are 

recommended.

(2) If scrapped at a salvage yard, a certification of equipment destruction may 

be provided to the participant and NRCS by the salvage yard operator.

(3) NRCS staff may follow-up with a site visit to verify engine destruction.

Retrofits

Retrofit projects must install ARB-verified emission control systems meeting the 

following minimum standards:

A) For an uncontrolled diesel engine, the retrofit kit that must be verified to reduce 

NOx or NOx+NMHC (non-methane hydrocarbons) emissions to the applicable 

current Tier standard for a given engine type and size.

B) For an emission-certified (1996+ model year) diesel engine, the retrofit kit must 

be verified to reduce NOx or NOx+NMHC emissions by at least 15% from the 

applicable NOx or NOx+NMHC emission standard.

C) The retrofit kit to reduce PM must use the highest level ARB-verified technology 

available for the engine being retrofitted. 

A complete list of ARB-verified retrofits may be found via the Internet at:

Section 4: Emission Factors for Agricultural Engines

The emission estimation methods summarize the data needed to calculate the emission 

reductions and cost effectiveness of potential projects. Included data are engine 

emission factors, load factors, and other conversion factors used for calculating 

emissions.

At a minimum, emission calculations require the following data:

Engine Model Year

Engine Rated Brake Horsepower

Type of equipment the engine powers (to determine the load factor)

Annual hours the engine operations

Applicable emission factors

Emissions calculations will examine the emissions from the existing equipment to 

establish a baseline and the emissions from the new equipment. An emissions 

inventory will be developed based on this data to estimate the annual emissions or 

NOx, ROG (NMHC or VOC), and PM10 and to calculate the emission reductions that 

results from implementing this conservation practice.

Cost effectiveness calculations will generally not be used for ranking potential projects. 

Instead, the ranking criteria will consider cost effectiveness along with its criteria. 

However, any cost effective analysis used to determine program effectiveness will 

utilize a maximum cost-effective threshold determined by the State Conservationist or 

will default to a maximum value established by the most current State of California Carl 

Moyer Memorial Air Quality Standards Attainment Program guidelines.

Emissions Calculations

Pounds/hour = (EF g/bhp-hr) x (engine max rated bhp) x (load factor) x (1 lb/456 grams)

Tons/year = [(EF g/bhp-hr) x (engine max rated bhp) x (annual hours) x (load factor)]

Emission Reductions from Replacing Engines

Fiscal Year 2011

Guidelines, Policies, and Procedures

Combustion Systems Improvement

(Code 372)

Emission reductions are achieved by improving existing high polluting combustion 

systems. This category can provide real emission reduction benefits by retiring the high 

polluting equipment earlier than through normal attrition and replacing with new, cleaner 

technology.

In 1998, the California Air Resources Board identified diesel particulate matter as a toxic 

air contaminant. Exposure to diesel emissions may result in negative health affects. 

Diesel emissions also include oxides of Nitrogen (NOx), a precursor to ozone in smog 

formation that has also been shown to cause adverse health affects. Cost-effective 

measures for reducing the toxic air contaminants and NOx emissions can be achieve 

with early replacement of older agricultural equipment.

Eligible Projects

Replacing high polluting, fully functional engines with newer reduced-emission engines 

meeting the most current model year California emissions standards. 

Payments are available to replace an existing engine (engine repower) with a newer 

emissions certified engine instead of rebuilding the existing engine to its original 

specifications. The replaced equipment must perform a similar function as the old 

equipment. 

Replacing an engine, however, may not always result in the best value. Replacing only 

the engine on equipment may not be possible due to design constraints or the 

diminished value of the old equipment may not justify investing significant funds for 

engine replacement. These situations will be evaluated on a case-by-case basis. If 

approved, payments will be made for the reductions achieved from equipment replaced 

with new emissions technology.

If repowering with an engine meeting the current applicable emission standard is 

technically unfeasible, unsafe, or cost-prohibitive to develop at the time funds are

obligated, then the engine must meet the most current practicable, previously applicable 

emission standard. The participant must submit a written statement of reason provided 

by the engine manufacturer verifying that a particular piece of equipment cannot 

accommodate an engine meeting current specifications without major modifications, 

safety risks, exorbitant costs, or for which engine or equipment models for repowers are 

not available or feasible.

The replacement engine and equipment must be certified for sale in California and meet 

the most recent model year emission standards and/or emissions standards established 

by the local APCD or AQMD, if applicable. Once in operation, the engine and 

equipment must be used exclusively in California.

Significant air quality benefits can result if two or more engines are replaced with a 

single engine performing similar duties. Eligibility will be evaluated on a case-by-case 

basis by examining the estimated emission reductions and cost effectiveness.

The upgrading or installation of fueling stations and infrastructure is not eligible, 

including the expense of installing fuel storage tanks, construction of fueling depots, or 

construction of biodiesel manufacturing facilities.

Retrofits to an engine are eligible. A retrofit is the installation of an emission control 

system verified by the ARB, such as diesel particulate filters, diesel oxidation catalysts, 

or selective catalyst reduction systems. Retrofit technology may be installed on an 

existing engine that results in meeting current emission standards or on a new engine 

that results in additional emission reductions. 

The existing engine or equipment being replaced must be owned by the participant, 

have been used in the State of California for at least 12 months prior to the application 

submittal date, have some remaining life, and must be destroyed. 

Soon after being replaced, the old, existing engine and equipment (if applicable) must 

be destroyed. Destruction of the old engine and equipment permanently removes the 

existing, high emitting equipment from service and ensures that the emission reductions 

are real. It also prevents the existing equipment from being moved into another locale 

to continue emitting high levels of pollutants. The participant must therefore certify that 

the old equipment has been destroyed and rendered useless.

NRCS payments schedules are available and vary depending on the type and size of 

the new engine or equipment.

A minimum two-year contract period is required. The participant must initiate the project 

within the first year of the contract. Payment is initiated once all contract obligations are 

met.

Section 1: Definitions

Add-On Control Device: an air pollution control device, such as catalytic converter, 

that reduces the pollution in exhaust gas. The control device usually does not affect 

the process being controlled and thus is "add-on" technology, as opposed to a 

scheme to control pollution through altering the basic process itself.

Ambient Air Quality Standards (AAQS): National and State health- and welfarebased standards for outdoor air, which identify the maximum acceptable average 

concentrations of air pollutants during a specified period of time. A chart of the 

national and state AAQS is posted on-line at: 

www.arb.ca.gov/research/aaqs/aaqs2.pdf.

ARB: the State of California Air Resources Board.

Brake Horsepower (bhp): the measure of an engine's horsepower without the loss in 

power caused by the gearbox, generator, differential, water pump, and other 

auxiliary components that may slow down the actual speed of the engine. For 

Practice Code 372, the engine horsepower determination is based on the Rated 

Brake Horsepower.

Certified Compression-Ignited Engine: a Tier 1, Tier 2, Tier 3, Tier 4-Interim, and Tier 

4-Final compression-ignited engine certified by the EPA and/or the ARB. Tier 

schedule is on Table 1.

Certified Spark-Ignited Engine: a spark-ignited engine that is ARB-certified as 

specified in Title 13, Division 3, Chapter 9, Article 4.5, Section 2433 of the California 

Code of Regulations.

CIG (b) Eligible Counties: counties or areas within counties designated by the EPA as 

“nonattainment” of the NAAQS for a given pollutant are eligible for CIG (b) funding.

These counties are: Alameda, Butte, Calaveras, Contra Costa, El Dorado, Fresno, 

Imperial, Inyo, Kern, Kings, Los Angeles, Madera, Mariposa, Marin, Merced, 

Nevada, Mono, Napa, Orange, Placer, Riverside, San Bernardino, San Diego, San 

Joaquin, San Mateo, Santa Clara, Sonoma, Stanislaus, Sutter, Tulare, Tuolumne, 

Ventura, Yolo, and Yuba.

Compression-Ignited Internal Combustion Engine: an engine that uses the heat of 

compression to initiate combustion. 

Criteria Air Pollutant: derived from EPA, an air pollutant for which acceptable levels of 

exposure can be determined and an ambient air quality standard has been 

established, based on the pollutant’s characteristics and potential health and welfare 

effects. These pollutants include ozone, carbon monoxide, nitrogen dioxide, sulfur 

dioxide, particulate matter (PM10 and PM2.5), and lead.
Combustion Systems Improvement

FY2011 Guidelines, Policies, and Procedures

Diesel Engine: a compression-ignited internal combustion engine.

Diesel Exhaust Particulate Matter: the ARB designates diesel exhaust particulate 

matter as a toxic air contaminant (TAC) based on its potential to cause cancer, 

premature death, and other health problems. As a result, the ARB established 

several Airborne Toxic Control Measures (ATCM’s) that are codified in the California 

Code of Regulations. The ATCM’s establish emission standards to reduce diesel 

exhaust particulate matter and health risks. Diesel exhaust particulate matter 

ATCM’s are posted on-line at: www.arb.ca.gov/toxics/atcm/atcm.htm.

Drawbar Horsepower: is the power an agricultural tractor has to pull an implement. 

The power is determined by utilizing a special a dynamometer car coupled behind a 

tractor that keeps a continuous record of the drawbar pull exerted and the speed. 

For Practice Code 372, drawbar horsepower will not be used for comparison with 

rated break horsepower because this value varies under different operating 

conditions and does not necessarily correlate with the engine horsepower. 

Emergency Standby Engine: a stationary engine where the primary purpose is to 

provide electrical or mechanical power in an emergency and operate to provide 

electrical power or mechanical work during an emergency use. Limited nonemergency use may occur for maintenance and testing purposes, impending 

outages, or under a Demand Response Program administered by a utility.

Emission Control System: any device or system employed with engines or piece of 

equipment that is intended to reduce emissions. Examples of emission control 

systems include, but are not limited to, closed-loop fuel control systems, three-way 

catalysts, fuel injection systems, and combinations of the above.

Engine Repower: the replacement of an existing engine with a new, emissions certified 

engine instead of rebuilding the existing engine to its original specifications.

EPA: The United States Environmental Protection Agency.

Family Emission Limit (FEL): an emission level declared by the manufacturer for use 

in any averaging, banking and trading program and in lieu of an emission standard 

for certification. It serves as the applicable emission standard for determining 

compliance of any engine within an engine family under 13 California Code of 

Regulations Sections 2423 and 2327. Any ARB Executive Order reporting a FEL 

value exceeding an applicable NOx, NMHC+NOx, CO or PM emission standard is 

not eligible for NRCS payments. Only FEL values less than or equal to these 

emission standards are eligible.

Forklift: Applicability to this practice standard includes electric Class 1 or 2 rider trucks, 

large spark-ignition engine powered Class 4, 5 or 6 rider trucks, and Class 7 rough 

terrain forklifts as defined by the Industrial Truck Association and Occupational 
Combustion Systems Improvement

FY2011 Guidelines, Policies, and Procedures

November 15, 2010

Safety and Health Administration (OSHA). Electric Class 3 trucks are not forklifts for 

the purposes of this practice standard.

Gross Horsepower (ghp): for purposes of Practice Code 372, the maximum gross 

horsepower equals the rated break horsepower only when bhp information is not 

available.

Gaseous Fuel: a fuel that is a gas under standard conditions, including but not limited 

to: natural gas, methane, propane, butane, bio-gas, and liquefied petroleum gas 

(LPG).

Independent Source Test Contractor: a program administered by the ARB that 

approves private independent source testing contractors to conduct required 

compliance emissions verification testing. Source operators may select from a list of 

contractors. The ARB does not require that testing contractors be approved prior to 

conducting testing in California; however, approval is required if the contractor 

wishes to conduct source testing for compliance verification. A list of contractors is 

available at: www.arb.ca.gov/ba/icp/current.pdf.

Internal Combustion (IC) Engine: any spark- or compression-ignited reciprocating 

engine.

Lean-Burn Engine: an engine operated with an exhaust stream oxygen concentration 

of four percent by volume or greater. Mechanically, such engines may be equipped 

with turbochargers.

Mobile Source Certification: new motor vehicles and engines are certified by the ARB 

for emission compliance before they are legal for sale, use, or registration in 

California. Certification is granted annually to individual engine families and valid for 

one model year. Certifications are described through ARB Executive Orders, which 

are posted on-line at: www.arb.ca.gov/msprog/offroad/cert/cert.php

Nonattainment Area: a geographic area identified by the EPA and/or the ARB as not 

meeting either National AAQS and/or California AAQS standards for a given 

pollutant, respectively.

Non-Methane Hydrocarbon (NMHC): The sum of all hydrocarbon air pollutants except

methane.

NOx: a general designation pertaining to compounds of nitric oxide (NO), nitrogen 

dioxide (NO2) and other oxides of nitrogen. NOx is typically created during the 

combustion processes and are major contributors to ozone formation and acid 

deposition. NO2 causes adverse health affects, is a criteria air pollutant and a major 

component in smog formation. This designation does not include nitrous oxide 

(N2O), which is designated as a greenhouse gas.

Off-Road Compression-Ignition Equipment: Equipment that cannot be registered 

and driven safely on a road or was not designed to be driven on a road. Newer 

equipment uses engines certified by the ARB to the off-road compression-ignition or 

diesel engine standards. Such equipment is most commonly used in construction, 

mining, agriculture, and cargo handling equipment. These engines do not include 

engines at operating at stationary agricultural pump plants.

Off-Road Spark-Ignited Equipment: equipment that cannot be registered and driven 

safely on-road or was not designed to be driven on-road. Newer equipment uses 

engines certified by the ARB to the off-road spark ignition engine standards. These 

engines may be designed to use gasoline fuel, liquid petroleum gas (LPG), 

compressed natural gas, methanol fuel, or a combination of these.

Ozone: a form of molecular oxygen that consists of three oxygen atoms linked together 

(O3). Ozone in the upper atmosphere occurs naturally and protects life on earth by 

filtering out ultraviolet radiation from the sun. However, ozone at ground level is a 

noxious pollutant that causes numerous adverse health affects, is a criteria pollutant 

and the major component of smog. Ozone is not emitted directly, but is formed in 

the atmosphere through a complex chemical reaction involving hydrocarbons, oxides 

of nitrogen, and sunlight. Problematic ozone levels occur most frequently on hot 

summer afternoons. 

Ozone Precursors: chemicals involving reactive hydrocarbons and oxides of nitrogen, 

occurring either naturally or as a result of human activities, contribute to the 

formation of ozone.

PM: a general designation pertaining to particulate matter emissions. PM2.5 has an 

aerodynamic diameter equal to or less than 2.5 microns and PM10 has an 

aerodynamic diameter equal to or less than 10 microns as measured by the 

applicable State and Federal reference test methods. Their small size allows them 

to make their way to the air sacs deep within the lungs where they may be 

deposited, resulting in adverse health affects. PM also causes visibility reduction and 

contributes to regional haze.

PTO Horsepower: is the “usable” horsepower measurement at the power take-off 

(PTO) shaft’s output and is the power for tractor attachments. For purposes of

Practice Code 372, multiply the PTO horsepower value by 1.15 if the rated break 

horsepower or gross horsepower information is not available for an existing engine. 

This value will be used for comparison with the rated brake horsepower of a new, 

replacement engine.

Rated Brake Horsepower: the continuous brake horsepower rating specified for the 

engine by the manufacturer or listed on the nameplate of the unit without regard to 

any de-rating or modification. For Practice Code 372, this value is the basis for 

engine rated horsepower.

Retrofit: the installation of an ARB-verified emission control system on an existing 

engine. Examples include, but are not limited to, diesel particulate filters and catalyst 

systems on spark-ignited engines. Verified technologies for diesel engines are 

posted on-line at: www.arb.ca.gov/diesel/verdev/vt/cvt.htm.

Rebuilt or remanufactured: engines offered by the original engine manufacturer 

(OEM) or by a non-OEM rebuilder who demonstrates to the ARB that the rebuilt 

engine and parts are functionally equivalent from an emissions and durability 

standpoint to the OEM engine and components being replaced.

Reactive Organic Gas (ROG): sometimes referred to as non-methane hydrocarbons 

(NMHC), a photo-chemically reactive chemical gas composed of non-methane 

hydrocarbons that may contribute to ozone formation. 

Rich-Burn Engine: an engine operated with an exhaust stream oxygen concentration 

of less than four percent by volume. Mechanically are naturally-aspirated engines.

Rough Terrain Forklift: Class VII forklifts powered by compression-ignition engines

and equipped with pneumatic tires that handle uneven surfaces. Such forklifts

include straight-mast and extended-reach forklifts.

Spark-Ignited Internal Combustion Engine: a liquid or gaseous fueled engine 

designed to ignite its air/fuel mixture by a spark across a spark plug.

Tier 1, Tier 2, Tier 3, and Tier 4 Engines (See Table 1 for the applicable Tier 

schedule):

(1) an EPA-certified compression-ignited engine that meets the Tier 1, Tier 2, or Tier 

3 emission standards of Table 1 on page 56970 of the Final Rule (October 23, 

1998) or the Tier 4 emission standards of Table II.A.2 (Tier 4 NOx and NMHC 

Standards and Schedule) on page 38971 of the Final Rule (June 29, 2004) or 

Table II.A.4 (Tier 4 Standards for Engines Over 750 HP (G/BHP-HR)) on page 

38980 of the Final Rule (June 29, 2004), respectively.

(2) An ARB-certified compression-ignited engine that meets the standards according 

to Title 13, Section 2423(b)(1)(A) and/or Title 40, CFR, Part 89.112(a) of the 

California Code of Regulations. Tier 4 engines that are subject to the interim or 

final after-treatment based Tier 4 emission standards in Title 13, Section 

2423(b)(1)(B) and/or Title 40, Part 1039.101 of the California Code of 

Regulations. This also includes engines certified under the averaging, banking, 

and trading program with respect to the Tier 1, 2, and 3 Family Emission Limits 

(FEL) listed in Title 13, Section 2423(b)(2)(A) and/or Title 40, Part 89.112(d) of 

the California Code of Regulations and to the Tier 4 FEL listed in Title 13 Section

Toxic Air Contaminant (TAC): an air pollutant, identified in regulation that may cause 

or contribute to an increase in deaths or in serious illness, or which may pose a 

present or potential hazard to human health. TACs are considered under a different 

regulatory process than that of criteria pollutants. 

Uncontrolled Compression-Ignition Engine: also referred to as “Tier 0”, is any diesel 

engine not meeting any established Tier emission standard. Generally, these are 

engines manufactured:

1999 and earlier: >750 hp

1998 and earlier: 25-49 hp

1997 and earlier: 50-99 hp

1996 and earlier: 100-174 hp

1995 and earlier: 175-750 hp

Volatile Organic Compounds (VOCs): many definitions describe VOCs, but are 

primarily organic, carbon-containing compounds having high enough vapor pressure 

under normal conditions to vaporize into the atmosphere. VOCs defined in a legal or 

regulatory concept are carbon compounds that contribute to the formation of ozone, 

as many VOCs are exempt from regulation. For example, methane is a VOC that 

does not contribute to the formation of ozone, but is designated a greenhouse gas. 

VOCs by themselves may also be classified as toxic air contaminants (TAC’s). 

Other terminology describing the photo-reactivity of VOC includes Non-Methane 

hydrocarbons (NMHC); Reactive Organic Gases (ROG); and Total Organic Gases

(TOG).

Section 2: Stationary Heavy-Duty Engines

This category primarily refers to stationary (i.e. bolted to a foundation or concrete slab) 

or portable (i.e. mounted on a trailer or skid, but does not drive a vehicle) engines. For 

purpose of Practice Code 372, this section may also include auxiliary engines on mobile 

equipment provided that the auxiliary engine does not propel a vehicle. This section 

does not apply to any off-road or mobile equipment (such as a tractor powering an 

irrigation gear head or pump via a PTO). The majority of stationary heavy-duty engines

used in agriculture are used for crop irrigation.

The California Air Resource Board (ARB) established emission standards and 

requirements that regulate the sale, purchase, rental, lease, and operation of diesel 

engines, including stationary and portable equipment used exclusively in agriculture. In 

addition, an Air Pollution Control District (APCD) or Air Quality Management District 

(AQMD) may impose emission standards through a rule or require permits with 

emission limits that may be more restrictive than required by the ARB. It is 

recommended for the participant to first consult with the local APCD or AQMD to 

determine permitting and emissions requirements prior to seeking assistance from the 

NRCS.

Several California air districts and the Air Resources Board have established 

compliance deadlines phasing-out the continued use of older stationary engines,

including uncontrolled (Tier 0) diesel engines. Once a deadline has passed, no

emission reductions are achieved with replacing subject engines since they are no 

longer allowed to operate.

Program Requirements

New Installations, producers are encouraged to install new electric motors or electric 

technology in lieu of installing internal combustion engines.

Existing Engines:

A) Existing engines must be in operational condition and connected to the

for the current model year standards, and meet the most recent model year 

emission standards and/or emissions standards established by the local APCD 

or AQMD, as applicable. Once in operation, the engine and equipment must be 

used exclusively in agriculture within California.

C) California Air Resources Board Executive Orders for certified off-road engines 

are posted on the Internet at http://www.arb.ca.gov/msprog/offroad/cert/cert/php.

D) Engines where an ARB Executive Order specifies a Family Emission Limit (FEL) 

that exceeds the applicable emission standards are not eligible for NRCS 

payments. Only FEL values lower than the emission standards are eligible.

E) An engine repower may include a new Original Equipment Manufactured (OEM) 

remanufactured, or an ARB certified/recertified rebuilt off-road engine meeting 

the latest California emission standards. 

F) Spark-ignition engines must meet the application emission standards established 

by the ARB.

G) Replacement equipment must serve the same function and perform the same 

work equivalent as the existing equipment. Examples include:

(1) Replacing a loader with another loader or a tractor for another tractor; or,

(2) Replacing different types of equipment that will perform similar functions,

improve operations efficiency, and reduce emissions (such as replacing a 

tracked dozer used for disking with a wheeled tractor that will perform the 

same work).

This requirement may be waived on a case-by-case basis where general 

purpose farming equipment changes commodities.

H) The horsepower rating for the new, replacement equipment engine shall not be 

greater than 125% of the original manufacturer rated brake horsepower 

(baseline) for the existing equipment engine. In limited situations, this

requirement may be waived if the horsepower increase results in significant 

annual emission reductions. The participant must document that the 

replacement equipment will serve the same function and perform the same job 

as the old equipment. Requests for waivers will be evaluated on a case-by-case 

basis for the following:

(1) The original horsepower range is not available for the existing engine.

(2) The higher horsepower is required where the existing equipment is 

replaced by another type of equipment that will perform the same work, 

improve operations efficiency, and reduce emissions (i.e. tracked dozer to 

wheeled tractor for disking).

(3) The higher horsepower replacement equipment is the result of 

implementing a conservation system.

I) Equipment is in new condition, has not been sold or associated with any rental or 

lease agreement, and has less than 100 operating hours recorded on a 

permanently mounted non-resettable hour meter.

J) The replacement engine must report at least a 15% NOx reduction and no net 

increase in particulate matter emissions, compared with the applicable standards 

or emission levels for that engine year and type of application through ARB 

Certification Testing, EPA Certification Testing, or emissions testing at a 

laboratory approved by the EPA or ARB.

K) The participant is to maintain a record of new engine and equipment usage for at 

least the first five years of operation. Hours of operation may be accomplished 

by recording the readings from a fully operational hour meter at the beginning 

and end of each year.

L) For electric equipment, the participant must include a description whether battery 

chargers have been installed. If not, the participant should describe the number 

of the battery chargers to be installed.

M) At this time, replacement with zero-emissions equipment other than electric (i.e. 

fuel cell equipment) is not eligible for payments.

N) For emissions calculations and cost effectiveness purposes, the project life is 10 

years.

Replacing Multiple Existing-Equipment for New Equipment (“Two for One”):

Significant air quality benefits can result if the new equipment is replacing two or more 

existing equipment. All existing and new equipment must meet the eligibility 

requirements and are reviewed on a case-by-case basis. Replacing multiple equipment

November 15, 2010

units with one new unit is not intended as a means to increase the horsepower rating 

determination for the new engine or equipment, as any increase in horsepower of the 

new engine is limited to 125% of the baseline horsepower rating of the existing engine. 

The intent is to allow for additional emission reduction benefits by permanently retiring 

additional equipment earlier than through normal attrition, which might improve the final 

ranking scores for application prioritization.

A) The emission benefits are determined by subtracting the annual emissions from 

the new replacement engine from the sum of the annual emissions from all 

subject existing engines.

B) At a minimum, the new equipment must serve the same function and perform 

similar work as one of the existing equipment in order to be eligible. The other 

existing equipment may not necessarily be similar in type and functionality of the 

new equipment. The summed emission reductions (not the summed hp) will be 

used for ranking purposes. Examples include the following:

(1) An existing 92 hp 1979 tractor that operates 500 hours/year is retired for a 

new 105 hp Tier 3 tractor. In addition, a 150 hp 1985 loader that operates 

800 hours/year will be retired. In this example, the 92 hp tractor is used 

as the baseline hp rating (i.e. like for like), limiting the maximum hp rating 

of the new equipment to 115 hp (125% of 92 hp). The NOx emission 

reductions are:

Sum of existing engine emissions = 1.17 tons NOx/yr

1979: 0.43 tons = {(92 hp x 12.09 g/bhp-hr x 500 hrs/yr x 0.70)/907,200}

1985: 0.74 tons = {(150 hp x 10.23 g/bhp-hr x 800 hrs/yr x 0.55)/907,200}

New engine emissions = 0.11 tons NOx/yr

Tier 3: 0.11 tons = {(105 hp x 2.74 g/bhp-hr x 500 hrs/yr x 0.70)/907,200}

Total NOx emission reductions = 1.06 tons/yr (91% NOx reduction)

(2) An existing 152 hp 1981 loader and an existing 125 hp 1975 loader will be 

retired for a new 160 hp Tier 4 Interim loader. In this example, despite 

which equipment is directly replaced with the new, the maximum hp of the 

two like equipment may be used as the baseline hp rating, thus limiting the 

maximum hp rating of the new equipment to 190 hp. As with example 

number one, the new engine emissions will be subtracted from the sum of 

the existing engine emissions to calculate the emission reductions.

C) A single piece of equipment may utilize more than a single engine mounted on 

the unit. Such equipment are equipped with multiple engines that operate 

together to perform a single function or task (i.e. a PTO on a self-propelled 

engine plus an auxiliary engine). The horsepower from each engine may be 

summed to determine the overall existing horsepower baseline and the emission 
Combustion Systems Improvement

FY2011 Guidelines, Policies, and Procedures

Page 17

November 15, 2010

reductions. However, hours of operations for each engine may not be summed 

since multiple engines generally work together. The total emissions calculated 

from each engine may be summed. The maximum horsepower ratings for the 

new replacement equipment shall not exceed 125% of the summed horsepower 

of the existing equipment.

D) All existing engines and equipment used to achieve the additional emission 

benefits must be destroyed.

Retrofits

Retrofit projects must install ARB-verified emission control systems meeting the 

following minimum standards:

A) For an uncontrolled diesel engine, the retrofit kit that must be verified to reduce 

NOx or NOx+NMHC (non-methane hydrocarbons) emissions to the applicable 

current Tier standard for a given engine type and size.

B) For an emission-certified (1996+ model year) diesel engine, the retrofit kit must 

be verified to reduce NOx or NOx+NMHC emissions by at least 15% from the 

applicable NOx or NOx+NMHC emission standard.

C) The retrofit kit to reduce PM must use the highest level ARB-verified technology 

available for the engine being retrofitted. 

A complete list of ARB-verified retrofits may be found via the Internet at:

Section 4: Engine and Equipment Destruction

Engine and equipment destruction must be performed in a safe manner that avoids any 

risks to personal safety.

Personal Safety always comes first.

After being replaced, the existing engine and mobile off-road agricultural equipment 

must be destroyed. Destruction removes the existing high-emitting engines and 

equipment from service and ensures that the emission reductions are real and 

permanent. It also prevents the old engine and equipment from being rebuilt or moved 

into another locale to continue emitting high levels of pollutants. Therefore, destruction 

includes the engine, drive-train and vehicle structural components, which shall not be 

recycled to be used as parts where they may prolong the life of other engines or 

vehicles, or used to rebuild equipment for continued use.

Under certain circumstances, an existing Tier 2-certified diesel engine may be relocated 

and used to replace an uncontrolled Tier 0 or Tier 1-certified diesel engine. The 

replaced existing engine and equipment must then be destroyed.

Procedures for disabling and rendering engines and equipment permanently inoperable:

(A) Prior to disabling the engine and equipment, the existing engine and equipment 

must be in operable working condition.

(B) After being replaced, the existing engine must be physically disabled in such a 

manner to eliminate the possibility of future use. At a minimum, the old engine 

block must be punctured with at least a six inch diameter hole to include a portion 

of the oil pan rail (sealing surface).

(C) The structural components on mobile equipment must be physically 

compromised. At a minimum, this shall be accomplished by cutting the vehicle 

frame railings in half or by destroying bell-housing and transmission components 

if not equipped with a frame. 

(D) The disabled engine and equipment shall be properly disposed of at a 

dismantling facility approved by the NRCS. The approved dismantler will scrap 

the engine and equipment either by shearing, crushing, or shredding.

(E) The producer shall provide the NRCS with a written certification that the engine 

and associated equipment has been permanently destroyed. If destruction was 

performed by an approved dismantler, the dismantler will provide the producer 

with the written certification for submittal to the NRCS. The certification shall 

describe:

serial number and vehicle identification numbers.

The certification must also specify that no parts or components were or will be 

parted-out, used or sold as parts, or used to rebuild an engine or equipment that 

was intended for destruction.

(F) NRCS staff may follow-up with a site visit to verify engine and equipment 

destruction. Additional destruction procedures may also be directed to assure 

destruction.

Section 6: Emission Factors and 

Standards for Agricultural Engines

The emission estimation methods summarize the data needed to calculate the emission 

reductions and cost effectiveness of potential projects. Included data are engine 

emission factors, load factors, and other conversion factors used for calculating 

emissions.

At a minimum, emission calculations require the following data:

Engine Model Year

Engine Rated Brake Horsepower

Type of equipment the engine powers (to determine the load factor)

Annual hours the engine operations

Applicable emission factors

Emissions calculations will examine the emissions from the existing equipment to 

establish a baseline and the emissions from the new equipment. An emissions 

inventory will be developed based on this data to estimate the annual emissions or 

NOx, ROG (NMHC or VOC), and PM10 and to calculate the emission reductions that 

results from implementing this conservation practice.

Cost effectiveness calculations will generally not be used for ranking potential projects. 

Instead, the ranking criteria will consider cost effectiveness along with its criteria. 

However, any cost effective analysis used to determine program effectiveness will 

utilize a maximum cost-effective threshold determined by the State Conservationist or 

will a maximum value established by the most current State of California Carl Moyer 

Memorial Air Quality Standards Attainment Program guidelines.

Emissions Calculations

Pounds/hour = (EF g/bhp-hr) x (engine max rated bhp) x (load factor) x (1 lb/456 grams)

Environmental Quality Incentives Program

The purpose of the Environmental Quality Incentives Program (EQIP) is to promote agricultural 

production, forest management, and environmental quality as compatible goals; optimize 

environmental benefits; and help farmers and ranchers meet Federal, State, Tribal, and local 

environmental regulations.

EQIP is a continuous sign-up, voluntary, conservation program administered by the Natural 

Resources Conservation Service (NRCS) that provides financial and technical assistance for 

approved conservation practices based on a current conservation plan. 

In order to be considered eligible for EQIP the applicant must have a vested interest in 

production agricultural or non-industrial private forest land and meet other program eligibility 

requirements.

About the National Air Quality Initiative

Under the Food Conservation and Energy Act of 2008, the Secretary shall provide eligible 

producers with program support to address serious air quality concerns from agricultural 

operations and help meet regulatory requirements through the Environmental Quality Incentives 

Program (EQIP). During fiscal year (FY) 2013, the program is designed to help producers meet 

air quality compliance requirements, as well as, support practices which address impacts 

associated with greenhouse gases (GHG).

Interested owners and/or operators of land managed for agricultural production in the following 

counties may be eligible for the National Air Quality Initiative:

Alameda, Amador, Butte, Calaveras, Contra Costa, El Dorado, Fresno, Imperial, Inyo, 

Kern, Kings, Los Angeles, Madera, Marin, Mariposa, Merced, Mono, Napa, Nevada, 

Orange, Placer, Riverside, Sacramento, San Bernardino, San Diego, San Francisco, San 

Joaquin, San Luis Obispo, San Mateo, Santa Clara, Solano, Sonoma, Stanislaus, Sutter, 

Tehama, Tulare, Tuolumne, Ventura, Yolo, and Yuba.

Submitting an EQIP Application 

Interested applicants may apply for EQIP by completing Form NRCS-CPA-1200, Conservation 

Program Application, and submitting the application to the NRCS field office in person, by 

phone, email, or fax in the county which you own land or have an agricultural operation. 

There will be two application cut-off dates for ranking applications submitted for the fiscal year 

2013 National Air Quality Initiative, November 16, 2012, and February 15, 2013.

Applications submitted by the second application cut-off date, February 15, 2013, will be 

evaluated and ranked only if funding is available.

Requesting Conservation Planning Assistance

Interested applicants are encouraged to request conservation planning and technical assistance 

from a local NRCS field office to help with the development of a conservation plan; the basis for 

any EQIP application is a conservation plan. Some of the benefits of developing a customized

conservation plan include: helping you to comply with environmental regulations; preparing you 

for various conservation programs opportunities and identifying immediate or potential resource 

problems that could hurt your production.

How EQIP Works

EQIP initiatives are funding opportunities created to assure funds are available to resource 

priorities across various land use types, for special emphasis resource needs and to assure that 

underserved groups have access to assistance. 

An EQIP initiative is a ranking and funding pool where similar applications are evaluated. 

Applications for an EQIP initiative will be evaluated based on screening and ranking criteria that 

consider the benefits of planned conservation practices as identified by local, state and national 

priorities. The basis for an EQIP application is a conservation plan.

Please contact your local NRCS field office about EQIP eligibility and the application process or 

visit http://www.ca.nrcs.usda.gov/programs/eqip/eqip_program_eligibility.html and 

http://www.ca.nrcs.usda.gov/programs/eqip/how_to_apply_for_eqip.html.

Program payments are limited to $300,000 a person or entity for all contracts entered into during 

any six-year period. This limitation includes unpaid prior year contract obligations as of October 

1, 2008, as well as new contract obligations. For the purpose of applying this requirement, the 

six-year period will include those payments made in fiscal years 2009-2014.

Priority Resource Concerns

The primary goal of the National Air Quality Initiative is to achieve and maintain the healthbased National Ambient Air Quality Standards (NAAQS) within designated non-attainment 

areas of California. Financial assistance is targeted to counties that have been identified as 

having significant air quality resource concerns by being designated as non-attainment for Ozone 

and/or Particulate Matter. These areas experience air pollution levels that persistently exceed the 

National Ambient Air Quality Standards established by the Clean Air Act. Non-attainment areas 

can be found on-line at Environmental Protection Agency (US EPA) webpage, 

http://www.epa.gov/oar/oaqps/greenbk/ancl.html.

The National Air Quality Initiative will assist agricultural producers by implementing 

conservation practices that reduce oxides of nitrogen (NOx), volatile organic compounds (VOC), 

respirable particulate matter (PM10), and fine particulate matter (PM2.5) emissions from 

agricultural sources. 

Refer to Table 1: List of California Non-Attainment Counties for more information on the 

resource priority for each county included in the National Air Quality Initiative.

Typical Conservation Treatments

The typical conservation treatment for the National Air Quality Initiative is the removal from 

service and permanent destruction of high-polluting internal combustion engines used with inuse off-road mobile agricultural equipment and replacement with engines that meet current 

model-year California emission standards. 

Significant emission reduction benefits are achieved when high-polluting engines are retired 

earlier than through normal attrition and replaced with cleaner new model-year engines. The 

applicable NRCS practice standard is 372 – Combustion System Improvement.

Also offered through the initiative is the development of a Conservation Activity Plan (CAP) by 

a Technical Service Provider. An application to develop a Comprehensive Air Quality 

Management Plan (CAP-126) will receive ranking priority due to the resulting conservation 

benefits from identifying and addressing the air quality resource concerns. Technical Service 

Providers are listed online at http://techreg.usda.gov/.

Application Ranking Criteria for the National Air Quality Initiative

The purpose of the National Air Quality Initiative ranking criteria is to evaluate the 

environmental benefits of conservation treatments included in an EQIP application, i.e. the EQIP 

schedule of operations and conservation plan. An application ranking score is based on national, 

state and local ranking criteria and the cost-efficiency of conservation practices in the EQIP 

application. The cost-efficiency score is based upon broad averages of the cost and 

environmental benefits of each practice in the EQIP application.

The following sections list the national, state and local ranking criteria for the National Air 

Quality Initiative and are provided for reference only. Applications will be evaluated 

electronically by NRCS using the Application Evaluation and Ranking Tool (AERT).

National Ranking Criteria

Only question 1 and 4 are applicable to the National Quality Initiative; all other questions will be 

answered “No”.

1) If the application is for development of a Conservation Activity Plan (CAP), the agency will 

assign significant ranking priority and conservation benefit by answering “Yes” to the 

following question. Answering “Yes” to question 1a will result in the application being
