Background 

The Carl Moyer Memorial Air Quality Standards Attainment Program (CMP) and the 

Surplus Off-Road Opt-in for NOx (SOON) Provision provide funding on an incentive 

basis for the incremental cost of purchasing cleaner than required engines and equipment. 

Both programs are funded with the Carl Moyer Program SB 1107 and AB 923 funds. 

This is the 18th year of the CMP and the 12th year of the program with funding from SB 

1107 and AB 923. 

SOON Provision Implementation Guidelines

On July 11, 2014, the Board amended Rule 2449 - Control of Oxides of Nitrogen 

Emissions from Off-Road Diesel Vehicles, to revise the reference from Section 2449.3 to 

Section 2449.2 of Title 13 of the California Code of Regulation. On August 14, 2014, the 

amended Rule 2449 was submitted to CARB for approval. CARB approved Rule 2449 

and forwarded it on to U.S. EPA as a revision to the State Implementation Plan. As part 

of reviewing the approvability of Rule 2449, U.S. EPA indicated that the SOON 

Implementation Guidelines (Guidelines) should be amended to reference the appropriate 

section of the State Regulation. In addition, there is a desire to align the funding levels 

for the SOON Provision to be the same as the funding levels provided in the Carl Moyer 

Program. 

Proposal 

Carl Moyer Program 

This action is to adopt the attached resolution recognizing upon receipt up to $26 million 

from CARB into the Carl Moyer Program SB 1107 Fund (32) for implementation of the 
-3- 

FY 2015- accepting the terms and conditions of the FY 2015-16 

Carl Moyer Grant award. CARB has tentatively allocated $25,495,135 to the SCAQMD. 

Of this amount, $23,901,689 is designated for projects funding and $1,593,446 for 

administrative and outreach efforts. In addition, $3,824,270 is required from the 

SCAQMD as the local match, which will be provided from AB 923 funds. 

This action is to also approve the issuance of Program Announcements #PA2016-05 and 

#PA2016-06 for the Carl Moyer Program and the SOON Provision, respectively. The 

approximate amounts of available funding are $23 million for the Carl Moyer Program 

and $5 million for the SOON Provision. Additional funds may become available by the 

time of award approval, upon which more projects will be awarded up to the total amount 

of funds available. A detailed account of available funds from the Carl Moyer Program 

Fund, including earned interest and the split between the SB 1107 and the AB 923 funds, 

will be outlined at the time of award recommendations. 

The PAs are issued based on the current program guidelines and the revisions approved 

by CARB on December 18, 2015. The Carl Moyer PA solicits projects for on-road 

vehicles, off-road vehicles of small and medium size fleets, locomotives, marine and port 

applications and other vehicles and equipment. The SOON Provision PA solicits projects 

for off-road vehicles in large fleets. As in previous years, SCAQMD will only fund 

diesel-to-diesel applications when alternative fuel engines/vehicles are not commercially 

available or certified by CARB except for emergency vehicles. Approval of emergency 

vehicle applications will be on a case-by-case basis. Proposals for all categories will be 

due by 1:00 pm on Wednesday, June 1, 2016. Staff expects to finalize the review and 

evaluation of the proposals and recommend awards for Board approval at the October 

2016 Board meeting. The Carl Moyer Program and the SOON Provision PAs are 

attached. 

Execute and Amend Contracts 

Rule 2202 Air Quality Investment Program requires the SCAQMD to achieve emissions 

reductions credits with funds submitted by employers in lieu of having rideshare 

programs. To generate the required NOx emissions credits, proposals were evaluated 

from the latest oversubscribed Carl Moyer Program solicitation that closed on June 3, 

2015. This action is to fund the repower of three marine vessel projects operating in 

disproportionately impacted areas in an amount not to exceed $542,300, from the Air 

Quality Investment Fund, Rule 2202 Program (27). Total annual NOx and PM emissions 

reductions from the recommended projects are 2.8 tons and 0.1 ton, respectively. 

Furthermore, this action is to amend a contract with West Coast Equipment, LLC for the 

replacement of 7 old for 3 new off-road equipment with lower-emitting CARB-certified 

Interim Tier 4 engines with an increase in the funding amount by $28,499, and for a new 

total amount of $132,509 from the Carl Moyer Program SB 1107 Fund (32). 
-4- 

Amend SOON Provision Implementation Guidelines

Per discussions with the U.S. EPA on the SIP approvability of Rule 2449, staff is 

proposing amendments to the reference of the appropriate section under state law, 

Section 2449.2, Title 13 of the California Code of Regulations. In addition, staff is 

proposing that that the maximum funding amount for eligible replacement projects be the 

same as the funding level provided in the Carl Moyer Guidelines for off-road equipment 

replacement projects. The provisions referred to in the proposed amendment are already 

in effect and represent no change to existing requirements on affected fleets. This action 

is to approve the amendments provided in Attachment 4. 

Outreach 

In accordance with SCAQMD

advertising the PAs and inviting bids will be published in the Los Angeles Times, the 

Orange County Register, the San Bernardino Sun, and Riverside County Press 

Enterprise newspapers to leverage the most cost-effective method of outreach to the 

South Coast Basin. 

Additionally, potential bidders may be notified utilizing SCAQMD

listing of certified minority vendors. Notice of the PAs will be emailed to the Black and 

Latino Legislative Caucuses and various minority chambers of commerce and business 

associations, and place site (http://www.aqmd.gov

where it can be viewed by making menu selection 

Amend SOON Provision Implementation Guidelines

No public workshops were held by SCAQMD staff since the proposed amendments are 

administrative in nature and would only reference the appropriate section in the 

California Code of Regulation per discussions with the U.S. EPA. This will provide 

greater funding flexibility to eligible projects consistent with the Carl Moyer Guidelines 

for off-road equipment replacement projects. 

Program Guideline

At its July 8, 2005 meeting, the SCAQMD Board approved a long-term Program 

Guideline for the implementation of the Carl Moyer Program in the South Coast Air 

Basin. The proposed funding distribution for different equipment categories is made in 

this Board letter according to the criteria outlined in that Guideline with emphasis on the 

following priorities in order to achieve the highest emission reductions: 

- Goods Movement (40 percent allocation) 

- Environmental Justice (50 percent allocation) 

- Cost-Effectiveness 

- Low Emission Engine / Vehicle Preference 

- Early Commercialization of Advanced Technologies/Fuels 

- Fleet Rules 

- School Buses 
-5- 

Funding Distribution 

The CMP Guideline includes the requirement that at least 50% of the program funds must 

be spent in disproportionately impacted areas. At least half the funding allocated under 

SB 1107 and collected under AB 923 will be awarded to projects located in 

disproportionately impacted areas. It has been the policy of the SCAQMD to allocate at 

least 50% of all funding available in the CMP and the SOON Provision, including rollover funding from previous years and turnback funds, to disproportionately impacted 

areas. 

Disproportionately Impacted Areas Point Ranking 

The requirements of the CMP and the SOON Provision will be implemented according to 

the following criteria. 

1) All projects must qualify by meeting the cost-effectiveness limits established in the 

Program Announcement. 

2) All projects will be evaluated according to the following criteria to qualify for funding 

as a disproportionately impacted area: 

a) Poverty Level: Detailed socioeconomic information is not included in the 2010 

Census. Such data is collected yearly from a small percentage of the population 

on a rotating basis by the American Community Survey (ACS). All projects in 

areas where at least 10 percent of the population falls below the federal poverty 

level based on the 2008-2012 ACS data are eligible to be included in this category, 

and 

b) PM2.5 Exposure: All projects in areas with the highest 15 percent of PM2.5 

concentration measured within a 2 km grid will be eligible to be ranked in this 

category. The highest 15 percent of PM2.5 concentration is 11.10 micrograms per 

cubic meter and above, on an annual average, or 

c) Air Toxics Exposure: All projects in areas with a cancer risk of 894 in a million 

and above (based on MATES IV estimates) will be eligible to be ranked in this 

category. 

The maximum score will be comprised of 40 percent for poverty level and 30 percent 

each for PM and toxic exposures. Special circumstances exist in some areas, such as the 

Ports of Long Beach and Los Angeles. Since there are no residents within the ports, 

poverty ranking could not be established. In this case, the poverty ranking from the 

adjacent on-shore areas was extended to the ports since these populated areas are directly 

impacted by port activities. 

Benefits to SCAQMD 

The SCAQMD has supported a number of activities directed to the advancement of new 

technologies and commercialization of low-emission alternative fuel technologies. The 

successful implementation of the Carl Moyer Program and the SOON Provision are direct 
-6- 

results of these technology advancement activities. The vehicles and equipment funded 

under these Program Announcements will operate many years, providing long-term 

emission reductions. 

Resource Impacts 

CARB has tentatively allocated $25,495,135 to the SCAQMD under SB 1107 for 

implementation of the FY 2015- CMP. Of this amount, $23,901,689 is 

designated for project funding and $1,593,446 for administrative and outreach efforts. 

These funds shall be recognized into the Carl Moyer Program SB 1107 Fund (32). In 

addition, $3,824,270 is required as the local match from the SCAQMD, which will be 

provided from AB 923 funds. 

The total funding for the new contracts under the Rule 2202 Program shall not exceed 

$542,300 from the Air Quality Investment Fund, Rule 2202 Program (27). 

The total funding increase for the contract amendment shall not exceed $28,499 from the 

Carl Moyer Program SB 1107 Fund (32). 

The proposed amendments to the SOON Provision Implementation Guidelines are 

administrative in nature and have minimal administrative resource impacts. Existing 

SCAQMD resources are sufficient for continued implementation and enforcement of the 

rule and the Guidelines.

RULE 2449 SOON PROGRAM ADMINISTRATIVE GUIDELINES 

INTRODUCTION

Title 13, Section 2449 of the 

In-Use Off-Road Diesel-

(CARB) in July 2007. The regulation requires off-road diesel vehicle fleets to meet 

increasingly more stringent NOx and PM fleet average standards beginning in 2010 to achieve 

NOx and PM2.5 reductions. A provision of this rule (Title 13, CCR, Section 2449.2) allows 

air districts to opt-in and require the largest fleets to apply for funds to meet more stringent 

NOx targets, thereby achieving additional NOx reductions earlier. Emission reductions 

achieved must be surplus to those required from the statewide regulation (Title 13, CCR, 

Section 2449.1). 

The opt-in provision is also known as the Surplus Off-road Opt-in for NOx (SOON) program. 

If an air district formally opts-in to the SOON program, it is required to develop administrative 

and funding guidelines that outline additional provisions beyond existing guidelines such as 

the Carl Moyer Memorial Air Quality Standards Attainment Program (Carl Moyer Program) 

necessary to implement the SOON program. Pursuant to Section 2449.2(e)(7), any funding 

awards must be consistent with the Carl Moyer Program. The South Coast Air Quality 

Management District (SCAQMD) has adopted specific policies and procedures to implement 

the Carl Moyer Program. The policies and procedures for the implementation of the Carl 

Moyer Program will serve as the basis for the SOON program. Additional administrative or 

funding guidelines must be developed to implement the SOON Program. At a minimum, the 

additional guidelines must include project selection criteria, co-funding requirements, and 

reporting and monitoring requirements. 

Rule 2449 Control of Oxides of Nitrogen Emissions from Off-Road Diesel Vehicles, 

incorporates by reference Title 13, CCR, Section 2449.2. The following sets forth additional 

guidelines as required under Title 13, CCR, Section 2449.2 (f)(2). These guidelines will be 

reviewed, at a minimum, on an annual basis, and may be updated to reflect the most recent 

applicable Carl Moyer guidelines or other administrative or funding guidelines approved by 

the District Governing Board. 

GUIDELINES

The guidelines described below are proposed to be in addition to the most current Policies and 

Procedures for the Carl Moyer Program adopted by the SCAQMD Governing Board. Any 

fleet that operates off-road diesel vehicles in the SCAQMD that are subject to Title 13, CCR, 

Section 2449.2(b) must, after April 2, 2009, apply for funding for those off-road vehicles 

operating a majority of the time in the SCAQMD, and the emission reductions must be surplus 

to the provisions of Sections 2449.1, Title 13, CCR. 
Administrative Guidelines Rule 2449 - SOON Program 

SCAQMD - 3 - February 2016 

A. Vehicle Qualification / Eligibility in SOON Fleet 

Pursuant to Title 13, CCR, Section 2449.2(b)(2), a fleet is subject to the SOON requirements 

if it consists of more than 40 percent of Tier 0 and Tier 1 vehicles statewide as of January 1, 

2008, and operates individual vehicles within the district. 

1. Percentage of fleet that is Tier 0 and Tier 1 is based on vehicle number and not 

horsepower. However, calculation of the SOON NOx index and SOON NOx targets 

in section 2449.2 (d)(1)(B) and 2449.2 (d)(1)(C) will be based on each engine. For 

example if a vehicle has two engines then the NOx Index and NOx target calculations 

will be determined using each engine separately and not as the total horsepower 

combined. 

Operated within the district is defined [Title 13, CCR, Section 2449.2(c)(2)] as a vehicle 

that currently operates in the district and for the three years immediately preceding the 

SCAQMD SOON program announcement deadline, operated more than 100 hours 

annually, and operated more hours within the boundaries of the SCAQMD than any other 

air district 

2. t. 

Currently operates is defined as having operated or will operate in the 

SCAQMD during the year immediately preceding the active SOON program 

announcement deadline. 

Operated more hours within the SC er 

district

boundaries in the three years immediately preceding the active SOON 

program announcement deadline are greater than the total hours operated over 

the same timeframe within any other sin

3. Pursuant to Section 2449.2(d)(2) fleets with a statewide maximum horsepower (hp) 

less than or equal to 20,000 (hp) are not subject to the SOON provisions, but may 

apply for SOON funding if they do not meet the SOOn NOx targets. 

4. Pursuant to Section 2449.2 (e)(8), fleets with vehicles that qualify for inclusion in the 

SOON program but are planning to move vehicles out of the SCAQMD such that the 

vehicles will not operate enough hours in the SCAQMD to qualify for SOON 

funding, are not required to include such vehicles in meeting the NOx index 

calculation in Section 2449.2 (d)(1)(B), the NOx target rate calculation in Section 

2449.2 (d)(1)(C), and the application for funding requirements of the SOON program. 

The vehicle must meet all requirements of Section 2449.2 (e)(8) to qualify for this 

provision. 

5. If a fleet has a vehicle that has been retrofitted within the last six years with a Level 2 

or 3 VDECS, which was the highest level VDECS at the time of retrofit, the fleet may 

but is not required to apply for SOON funding for that vehicle. 
Administrative Guidelines Rule 2449 - SOON Program 

SCAQMD - 4 - February 2016 

B. Compliance Plan Requirements 

Title 13, CCR, Section 2449.2(e)(3), requires fleets applying for SOON funding to submit a 

compliance plan in addition to their application. The compliance plan must describe actions 

the fleet must take to meet the fleet average and BACT requirements of the statewide regulation 

(Title 13, CCR, Section 2449.1)and actions to meet the more stringent SOON NOx fleet 

targets. SCAQMD would review and provide its initial approval within 45 days after a plan is 

deemed complete. (CARB has a separate approval process, which the SCAQMD would work 

Information that must be 

submitted as part of the compliance plan includes: 

1. Fleet Information

a. Information required as part of Title 13, CCR, Section 2449(g)(1)(B), for each 

vehicle and includes: 

Vehicle type; 

Vehicle manufacturer; 

Vehicle model; 

Vehicle model year; 

Vehicle serial number; 

If vehicle is permanent or year-by-year low use, specialty, dedicated 

emergency, dedicated snow removal, or is used for agricultural operations for 

over half of its annual operating hours; 

For each engine that propels the vehicle, the engine manufacturer, USEPA 

certified engine family (if any), engine serial number, engine model year 

and/or production year, engine maximum horsepower (net horsepower, or net 

flywheel horsepower as certified by the Society of Automotive Engineers 

(SAE), or if this is not readily available, a horsepower on the label of the 

engine, or in the service literature for the engine can be used), or estimate the 

horsepower by multiplying the power take off by 120 percent, type of retrofit 

emission control (if any), date installed, and its verification level. 

Whether the vehicle has been retrofit, repowered, or replaced with SOON 

funding, and if so, the start and end of dates of the contract period. 

b. Information necessary to demonstrate eligibility for vehicles subject to SCAQMD 

SOON provisions: 

Percentage of Tier 0 and Tier 1 equipment as of January 1, 2008 

Total fleet horsepower subject to CARB regulation 

Vehicle operational time and location for past three (3) years 

Whether the vehicle is scheduled to leave the SCAQMD, and if so, the 

app

move the vehicle out of the SCAQMD. 

c. If credit will be taken for early repowers, retirements, or retrofits for the purpose 

of complying with the statewide rule, fleet information must be submitted from 

the year of the earliest action to the current year for all vehicles used to generate 

the early credits. 
Administrative Guidelines Rule 2449 - SOON Program 

SCAQMD - 5 - February 2016 

2. Fleet Actions 

Sufficient information must be supplied in the compliance plan detailing actions 

planned or taken on each piece of equipment in a fleet to meet the statewide 

requirements as well as the actions necessary to meet the SOON NOx targets. As the 

SOON NOx targets are set for every 3 years (2011, 2014, 2017, 2020, 2023), 

additional actions taken each year from the current year to the next two future 

applicable SOON NOx target date must be identified (e.g., if the compliance plan is 

being prepared for the year 2008, the plan must cover years through 2014). If credit 

will be taken for early repowers, retirements, or retrofits, fleet actions taken before 

the current year must be submitted for all vehicles used to generate the early credits. 

Information must include for each year and each vehicle: 

Action taken retire, replace, repower, or retrofit 

For replacement, all information listed in Section 2449 (g)(1)(B) for the new 

vehicle 

For repower, information about the new engine including engine 

manufacturer, engine family (if any), engine serial number, engine model 

year, engine maximum power, type of retrofit emission control equipment 

installed (if any), date installed and its verification level. 

For retrofit, type of retrofit emission control equipment, and verification level. 

C. SOON Application Requirements 

1. Application - 

Pursuant to Section 2449.2(d)(1)(D) a fleet must apply for sufficient funding to 

repower, replace, or retrofit vehicles so that the SOON portion of the fleet (all 

vehicles in the fleet that operated within the district) will meet or exceed the 

applicable fleet NOx target if all projects were funded. The application and all 

necessary information needed as part of the application are explained in the program 

announcement. Information required includes: 

Contact information

Vehicle information (make, model, model year, etc.)

Project life (ranges3 to 10years)

Project type 

Vehicle activity information (i.e. fuel usage, hours of operation)

Cost information (including vendor quotes)

2. High Priority Request - 

Pursuant to Title 13, CCR, Section 2449.2 (d)(1)(D), fleets must designate for each 

SOON program project application whether they wish the project to receive high 

priority for funding. 

3. Annual Hours of Operation - 

nnual hours of operation will be equal to the average of the operating 

hours in the SCAQMD over the two years immediately preceding the active SOON 

program announcement deadline. The hours the vehicle operated in the SCAQMD 
Administrative Guidelines Rule 2449 - SOON Program 

SCAQMD - 6 - February 2016 

will be used to calculate the project cost effectiveness as well as the subsequent 

requirement of minimum operating time in the district should the project receive 

funding. For example, should a vehicle operate on average for the past three years 

400 hours each in two other air districts and 500 hours in the SCAQMD that vehicle 

would qualify for the SCAQMD SOON program, but only for the 500 hours it 

averages in the SCAQMD. The vehicles cost-effectiveness would be evaluated on 

the 500 hours, and should the vehicle receive funding, it would be required to operate 

on the average, 70% of its 500 hours or 350 hours annually in the SCAQMD for the 

life of the project. 

D. Operational Requirements 

1. Contract duration 

Minimum contract duration or project life ranges between three (3) to ten (10) years 

unless otherwise noted in the program announcement. 

E. Project Award 

The first 75% of the available funding will be awarded strictly on cost-effectiveness criteria. 

A $5,000 per ton of NOx reduced cost-effectiveness value will be used as the benchmark. 

Most projects are expected to be below this benchmark (i.e. will be more cost-effective). 

However, projects at higher cost-effectiveness values can still be funded as long as they are 

below the cost-effectiveness cap mandated by the applicable Moyer Guidelines. The 

remaining 25% will be distributed to the most cost-effective project presented by each fleet 

with the goal of funding at least one project per fleet. The funding will be distributed beginning 

with the most cost-effective projects presented by a fleet not having received funding in the 

first round and requesting high priority for the projects until the 25% of the funding is all 

awarded. If funding is still available after all fleets have at least one project funded, the 

remaining funds will go to the next most cost-effective projects available from all of the fleets. 

At no time will a fleet receive more than 10% of the available SOON funding. All other 

criteria being equal, projects greater than 250 horsepower will receive funding before projects 

less than 250 horsepower. 

F. Co-funding 

Most SOON projects are expected to be repowers to Tier 3 engines or cleaner. SOON repower 

projects will be funded at the full incremental cost of the repower which will require the project 

owner to co-fund 15% of the cost of the repower with the SOON program providing 85% of 

the repower costs. The exception to this requirement is where it could reasonably be 

determined that the fleet would not have incurred the rebuild cost (e.g. the replaced engine was 

recently rebuilt). For the purpose of this provision, a rebuild refers to a rebuild of an engine 
Administrative Guidelines Rule 2449 - SOON Program 

SCAQMD - 7 - February 2016 

power assemblies or make other changes that significantly increase the service life of the 

cooler or 

service life of the engine. The following maintenance does not constitute a rebuild: 

(1) Scheduled emission-related maintenance during the useful life period (such as replacing 

fuel injectors). 

(2) Unscheduled maintenance that occurs commonly within the useful life period. For 

example, replacing a water pump is not rebuilding an engine. 

If the engine rebuild was completed in the 12 months prior to the contract date, the grantee 

must provide the SCAQMD with documentation of the rebuild to qualify for this provision. 

Rebuild documentation may include, but is not be limited to, dated work orders, sale invoices 

for parts, and/or maintenance records. For engine rebuilds completed in the 13 to 36 months 

prior to the contract date, the grantee must provide the SCAQMD with documentation of the 

rebuild a

equal to or greater than the contract project life plus the time since last rebuild to qualify for 

this provision. Documentation for extended rebuild intervals includes, but is not limited to, 

historical maintenance records for the equipment or fleet policy on rebuild intervals. Engine 

rebuilds completed more than 36 

do not qualify for this provision. 

G. Vehicle Replacement 

The maximum funding amount for eligible SOON replacement projects shall be the 

same as the funding level provided in the most recent CARB approved version of the 

Carl Moyer Guidelines for off-road equipment replacement projects.
