EMISSION REDUCTION ANALYSIS FOR 

RULE 9510 (Indirect Source Review) 

I. INTRODUCTION 

Both the 2003 PM10 Plan and the Extreme Ozone Attainment Demonstration Plan, 

contain emissions reduction commitments for proposed Rule 9510 of 4.1 tons per day of 

NOx and 5.2 tons per day of PM10 to be achieved by 2010. Those estimates were 

based on assumptions at the time and are commitments that are necessary to assist the 

district in meeting the federal and state PM10 and ozone standards. This appendix 

contains emissions and emissions reduction estimates that update those original 

estimates. 

II. BASELINE EMISSIONS 

A. Sources of Emissions from New Development 

It is generally accepted in both air quality and transportation planning, as well as in case 

law that new emissions occur from new development. The construction of new 

structures is undertaken in order to accommodate the growth in population of a 

particular area. With the projected growth and development in the San Joaquin Valley 

Air Basin (SJVAB), there will also be a corresponding growth in emissions from energy 

usage, landscape maintenance equipment, wood combustion, motor vehicles, and 

entrained dust from paved and unpaved roads. 

Energy Usage

Emissions associated with energy usage from new development primarily occur from 

two different sources, electricity generation and fuel combustion. NOx and PM10 

emissions result from using space heating, water heating, cooking, and from other 

miscellaneous electrical appliances/equipment. ARB estimates fuel combustion 

emissions from natural gas, distillate oil or LPG, using EPA emission factors, and gas 

sales.1

 Emissions attributed to use of electricity generated at power plants are not 

easily quantified due to the variety of sources that supply electricity, which are located in 

and out of the basin and the state. Therefore, electrical generation emissions 

associated with new development will not be quantified or addressed for this program.

Landscape maintenance equipment

Landscape maintenance equipment generates NOx and PM10 emissions from fuel 

combustion (gasoline, diesel, or LPG or CNG) and from evaporation of unused fuel. 

Equipment in this category can include leaf blowers, lawn mowers, trimmers, edgers, 

chainsaws, chippers, etc. ARB uses the OFF-ROAD model to estimate PM10 and NOx 

emissions using population, activity duration, and emission factors.2 URBEMIS uses 

OFF-ROAD results and quantifies emissions by the number of homes and business 

units.3

 Based on District analysis, the growth in NOx and PM10 emissions from 

residential landscape maintenance equipment is relatively small, 15 tons per year, 

despite a projected increase of nearly 1.8 million pieces of residential landscape 

equipment in the SJVAB. The primary reason for the small emissions increase is that 

the new equipment is significantly cleaner than the older equipment. 

Wood Combustion

Residential wood combustion emissions of PM10 and NOx come from burning wood or 

similar materials inside fireplaces, wood stoves and inserts. ARB estimates emissions 

totals using the following factors: tons of wood used per house, BTU rating per cord, 

number of houses, fraction of active wood combustion devices, average number of days 

burned per house, and other representative factors.4 The recent amendment to Rule 

4901 (Wood Burning Fireplaces and Wood Burning Heaters) will reduce a significant 

portion of emissions from those devices. Rule 4901 contains limits on wood combustion 

devices in new development, however, it still allows new devices in a development of a 

certain size or larger. Therefore, reductions from this category can still occur if the 

development can still install those devices and chooses not to. 

Motor Vehicle Emissions

Motor vehicle emissions is the largest category of emissions attributed to new 

development. The inventory includes estimates of exhaust and evaporative VOCs, 

NOx, and PM10 associated with exhaust, tire wear and brake wear. On-road motor 

vehicles account for approximately 43% of the entire NOx inventory for 2002.5 ARB 

estimates emissions from on-road vehicles using the EMFAC2002 model, which uses 

emission factors, vehicle numbers and vehicle activity. Emission rates are derived 

primarily from direct testing by the state or EPA. Vehicle population and vehicle age 

data are obtained from the Department of Motor Vehicles (DMV). Travel activity, which 

includes vehicle miles traveled (VMT), distribution of VMT by speed, the number of trips 

taken per vehicle each day, are provided by the California Department of Transportation

(Caltrans), local Metropolitan Planning Organizations (MPOs), local Councils of 

Governments (COGs), and fleet monitoring.6 URBEMIS quantifies vehicle emissions 

attributed to a particular development based on the emission factors and vehicle activity 

found in EMFAC2002, in combination with project specific data. While the motor vehicle 

emissions inventory in both the PM10 and ozone plans show that vehicle emissions are 

declining, emissions would have declined even more if growth were not to occur, thus 

hampering the ability of the region to reach attainment of the PM10 and ozone 

standards. The following chart shows the emissions from all motor vehicles for the 

current population if it would have remained constant (No-Growth), and the emissions 

from vehicles for the projected population as reported in the 2003 PM10 Plan emissions 

inventory (Growth). Based on an analysis performed by ARB using EMFAC2002, 

which can be found in Attachment 1, the difference is an estimated 17.3 tons per day of 

NOx attributed to projected increase in growth in the SJVAB between 2006 and 2010.

Re-entrained Road Dust

PM10 emissions from road dust occur by vehicles driving on unpaved roads, or by 

vehicles entraining or re-entraining dust on paved roads. ARB estimates PM10 

emissions by using the following factors for different road types: silt loading on roads, 

vehicle weight, and VMT traveled. The majority of new development occurs on or 

creates new paved roads, however, some development in rural areas still use unpaved 

roads. Unpaved road emissions are estimated by using an emission factor and total 

VMT traveled.7

Construction

This category of emissions differ slightly from the others, since all emissions from 

construction are due to new development, regardless of growth in the category. 

Emissions associated with construction activities occur for the purpose of building 

residential, commercial, industrial, institutional, or governmental structures. Emissions 

result predominantly from equipment associated with site preparation work, which may 

include scraping, grading, loading, digging, compacting, and other operations. ARB 

estimates construction emissions by utilizing a computer model called OFF-ROAD. The 

construction emissions in the OFF-ROAD model are estimated using the population, 

activity, and fuel usage of the varied types of construction equipment. 

The following figure demonstrates PM10 emissions and emissions growth from 

construction equipment, re-entrained paved road dust, and vehicle exhaust associated 

with new development.

It should be noted that some sources of emissions from new development are not 

included in the above table for several reasons. While there may be difficulties in 

assessing what portions of the emissions inventory are resulting from new growth, there 

are new emissions from growth occurring. Therefore, the above table represents a 

conservative estimate of what will occur, and does not overestimate. Therefore, any 

reductions applied to the emissions outlined in the above table will represent a 

conservative estimate of actual reductions resulting from this program. 

III. EMISSIONS REDUCTION OPTIONS FOR NEW DEVELOPMENT 

A. On-site Project-Specific Emissions Reductions 

On-site mitigation measures and their corresponding emission reduction methodologies 

were developed by Nelson/Nygaard and put into URBEMIS. The following discussion 

lists measures/conditions, if implemented that would result in emissions reductions from 

a development project. The maximum percent reduction is in general terms. The actual 

reduction relies on project specific information and factors, and how the mitigation 

measure is used in combination with other measures. 

Increase Energy Efficiency Beyond Title 24 

This measure would reduce emissions by decreasing the amount of natural gas that is 

needed and in turn combusted for a particular development. Examples of how this 

could be achieved include: using insulation in the attic and walls, insulating ductwork, 

using whole house fans, double-paned and/or high performance glazed windows, 

maximizing the use of natural lighting, installing EnergyStar appliances, orienting the

B - 7

building north or south to utilize passive heating and cooling, designing the building to 

maximize natural ventilation, or any number of other items that would decrease the use 

of natural gas, and therefore decrease emissions. The emissions reductions associated 

with this mitigation measure in URBEMIS would require a quantification of the % 

reduction beyond what is already required by Title 24 as determined by a computer 

model developed for Title 24 purposes. 

Electrical landscape maintenance equipment 

This measure would reduce emissions by eliminating some or all of the combustion of 

gasoline or diesel in standard landscape equipment by replacing it with equipment that 

relies on batteries, an electrical outlet, or manually-powered equipment. Emissions 

reductions are quantified by using the % of the development that would use noncombustion powered equipment. 

Hearth

This measure would reduce emissions by eliminating construction of a wood 

combustion device that would have otherwise been allowed under Rule 4901. 

Net Residential Density 

Emissions reductions from this measure would occur when an individual from a 

particular residential use forgoes the use of the automobile and uses an alternate form 

of transportation. A considerable volume of research has investigated the links between 

density and travel behavior and has determined that there is a significant and 

quantifiable relationship between residential density and automobile use. Three key 

studies of travel behavior and density itself have identified elasticities, which has been 

used to develop a formula to determine the reduction in vehicle trips and vehicle miles 

traveled, and the corresponding emissions reductions. The maximum reduction in 

trips/VMT and resulting emissions that may occur from this measure is calculated to be 

55%. 

Mix of Uses 

Emissions reductions from this measure would occur when an individual forgoes the 

use of the automobile and uses other forms of transportation. Research has shown that 

there is an impact of diversity or mix of uses on travel behavior, which can occur at the 

macro-scale, such as jobs-housing balance. Numerous studies of travel behavior and 

mix of uses have identified elasticities, which has been used to develop a formula to 

determine the reduction in vehicle trips and vehicle miles traveled, and the 

corresponding emissions reductions. The maximum reduction in trips/VMT and 

resulting emissions that may occur from this measure is calculated to be 9%. 

Local Serving Retail 

Emissions reductions from this measure occur when an individual forgoes the use of the 

automobile, since the proximity of the retail encourages other forms of transportation. 

The maximum reduction in trips/VMT and resulting emissions that may occur from this 

measure is calculated to be 2%.

 Rule 9510 and Rule 3180

B - 8

Transit Service 

Emissions reductions from this measure would occur when an individual forgoes the 

use of the automobile and uses transit. Transit choices could include buses, light rail, 

dedicated shuttles, and trolleys. Since emissions from transit services already exist, the 

elimination of trip(s) from the automobile would result in emissions reductions. 

URBEMIS determines emissions reductions from transit use based on a Transit Service 

Index, which is based on the latest California-specific research on transit use. The 

maximum reduction in trips/VMT and resulting emissions that may occur from this 

measure is calculated to be 15%. 

Bicycle and Pedestrian Facilities 

Emissions reductions from this measure would when an individual forgoes the use of 

the automobile and uses a bicycle or walks. Since the use of a bicycle or the action of 

walking does not emit emissions, the elimination of trip(s) from the automobile would 

result in emissions reductions. URBEMIS determines emissions reductions from bicycle 

use and pedestrian activities based on quantitative values of network density, sidewalk 

completeness and bike lane completeness. The maximum reduction in trips/VMT and 

resulting emissions that may occur from this measure is calculated to be 9%. 

Affordable Housing/Senior Housing/ Assisted Living 

This measure would reduce emissions by designating residential units as deedrestricted below-market-rate (BMR) housing. Research has shown that lower-income 

households and senior citizens own fewer vehicles and drive less. By designating 

residential units as deed-restricted BMR, only lower-income individuals that use the 

automobile less would occupy those units, which would result in lower emissions due to 

less automobile use. The maximum reduction in trips/VMT and resulting emissions and 

resulting emissions that may occur from this measure is calculated to be 4%. 

Transportation Demand Management Programs 

TDM Programs can include free transit passes, parking restrictions and telecommuting. 

Emissions reductions from this measure would occur when a landlord provides an 

incentive, such as transit passes, to individual(s), who then forgoes the use of the 

automobile and uses transit. These programs provide an incentive for the individual(s) 

to use the transit, and studies have show that these programs both increase transit 

ridership and reduce vehicle trips. The maximum reduction in trips/VMT and resulting 

emissions and resulting emissions that can be achieved under this measure is 25%. 

Fleet Modifications

Reductions from this measure occur when a fleet owner makes vehicle specific 

modifications or agrees to purchase and/or use only vehicles with controls, such as a 

particulate filters or catalysts. There are numerous options available. The maximum 

reduction in emissions that can be achieved under this measure varies by control 

option.

B - 9

It is important to note that many of the mitigation listed above requires a change in 

travel behavior of an individual in order for the emissions reductions to occur. It is not 

guaranteed that the mitigation measures will be successful at changing travel behavior 

to the exact amount as calculated, however, it represents the best estimate/projection of 

what will occur based on the most recent research conducted on existing travel 

behavior to date. 

B. Off-site Emissions Reductions 

In the event that the emissions impact of a particular project is not fully mitigated on site 

a proportional fee will be assessed and collected for the NOx and PM10 emissions not 

mitigated. The fees collected would be placed into a mitigation fund for each pollutant 

and county, and expended on projects that reduce emissions of that pollutant in that 

county, utilizing a grant-like program. The district has over eleven years experience 

with grant programs designed to reduce primarily NOx, and some VOC. Each grant 

program has had strict guidelines on emissions reductions, qualifying equipment, and 

the related administration of the program. Based on that experience, the District has 

decided that a grant program would provide the most cost-effective emissions 

reductions for the money that will be collected. 

The District has employed the California Air Resources Board (ARB) and the California 

Department of Transportation document “Methods to Find the Cost Effectiveness of 

Funding Air Quality Projects” for finding the cost effectiveness and emission reduction 

benefits for a wide variety of emission reduction projects. This document can also be 

accessed through an associated on-line database. The methods described are 

generally accepted and include: a list of information needed to calculate cost 

effectiveness, emission factors, project life, defaults that may be used when projectspecific data is not available (assumptions) and formulas to calculate vehicle emission 

reductions for three major pollutants, NOx, PM10, and VOC’s. Many of those methods 

were used to develop the grant programs that could be funded under this program. 

The most successful District grant program has been the Heavy-Duty Engine Incentive 

Program. This program replaces older model high polluting engines with newer and 

cleaner burning engines. Eligible project types funded under the heavy-duty program 

include, but are not limited to: on-road and off road vehicles and equipment, agricultural 

pump engines, marine vessels, forklifts, truck stop electrification technology, and school 

bus projects. 

The Voluntary Accelerated Vehicle Retirement (Scrap) Program is designed to 

accelerate the voluntary retirement of older, higher polluting passenger vehicles. 

Monetary incentives are provided to individuals who agree to scrap their high polluting 

passenger vehicles. Ideally, this incentive money will help them purchase newer 

vehicles with cleaner burning engines.

B - 10

The Light and Medium Duty Vehicle Incentive Program is designed to encourage the 

purchase and use of cleaner engine technology for passenger vehicles. To be eligible 

under the program, the light and medium duty vehicles must be powered by natural gas, 

electricity, fuel cells, or gasoline-electric hybrid technology. 

The Carl Moyer Program provides incentive funds for significant near-term reductions in 

NOx. Eligible project types under the Carl Moyer Program include: new alternative fuel 

vehicle projects, on and off-road vehicle engine replacement projects, agricultural pump 

engine replacements, locomotive engine replacements, marine vessels, forklifts, and 

airport ground support equipment engine replacements. Projects are funded based on 

cost effectiveness, utilizing criteria developed by the state in coordination with the air 

districts and the statewide Incentive Program Implementation Team (IPI). 

In addition to the sources listed above, the District receives grant funds from other state 

and federal funding sources including: the State’s Lower Emission School Bus Program, 

Peaker Plant Offset funds, and the State’s NOx and PM Program funds. 

IV. EMISSIONS REDUCTION OPTIONS FOR CONSTRUCTION

Construction PM10 emissions can be mitigated in numerous ways. The following 

discussion lists measures/conditions, if implemented that would result in emissions 

reductions from construction activities. The percent reduction identified was based on 

the URBEMIS2002 Users’ Guide. 

A. On-site Reduction Options 

There are several on-site construction emissions reductions available. The following 

lists the current mitigation measures that reduce PM10 and NOx. There is a statewide 

effort to update the construction portion of URBEMIS, so there may be more mitigation 

measures identified that are not included in this appendix. 

Equipment Exhaust Control

There are several options available for controlling NOx and PM10 emissions from 

equipment used for construction. Options can include, purchasing newer equipment, 

altering fuel usage, modifying an engine, using exhaust after-treatments, or renting 

equipment that help meet the rule requirements. New equipment can provide a high 

percentage of emissions reductions, depending on the horsepower and the year of the 

equipment. Reductions that can occur from using newer equipment reductions range 

from 8-62% for PM10, and 20-38% for NOx. Different fuels are available for use that 

would reduce emissions from construction equipment. Ultra-low sulfur diesel can 

achieve a 5-9% reduction in PM10. Alternative diesel fuels can achieve 5-16% 

reduction in NOx and a 40-63% reduction in PM10. Diesel oxidation catalysts can 

reduce PM10 by 25-50%. Diesel particulate filters can reduce PM10 by 85%. Selective 

Catalytic Reduction can reduce NOx by 80% and PM10 by 25%.

B - 11

Worker Commute Trip Reductions

This measure would entail using a shuttle to take construction workers to a retail 

establishment for lunch. This would eliminate numerous trips, which would reduce 

vehicle exhaust, and entrained and/or re-entrained road dust. The maximum PM10 

reduction from this measure is 1.3%. 

B. Off-site Reduction Options 

Since any fees collected will reduce construction emissions off-site, the same emissions 

reduction options listed in section III above apply. 

V. PROJECT-SPECIFIC EMISSIONS REDUCTIONS 

Each development project, subject to Rule 9510, will have an assessment of the project 

performed. The assessment will include an APCO-approved model run that identifies 

the project or project phase baseline emissions and the emissions reduction resulting 

from on-site mitigation measures. The remaining emissions will be quantified and will 

fund emissions reduction project(s), using the fee formulas identified below. 

Area and Operational NOx Fee Formula

The NOx fee formula must identify the total tonnage of mitigation required, subtract the 

tonnage mitigated on-site, and multiply the remaining tonnage by the cost of reductions 

in order to determine the cost to reduce emissions off-site. 

Figure 3 

Baseline tons

Figure 3 represents a development project’s NOx emissions over a period of ten years. 

Section A represents the emissions reductions projected to be achieved from ARB’s 

tailpipe control, which is 25% of the total project’s 10 years emissions. The remaining 

75% is the project’s estimated NOx emissions for ten years. The mitigation required by 

Rule 9510 is represented by the triangle B, which equal to a third of the non-A section. 

Thus, the total tonnage of mitigation required can be identified as follows:

B - 12

Estimated Baseline Emissions (tons) x 10 years x 75%

3 

which is equal to: 

EBE (tons) x 2.5 

The next step is to subtract the percent reduction achieved from on-site mitigation 

measures. This is determined by using the estimated baseline emissions over ten 

years and applying the percent mitigation, as follows: 

Estimated Baseline Emissions (tons) x 10 years x 75% x Actual % Mitigation 

=EBE x 7.5 x APM 

Thus, 

(EBE x 2.5) - (EBE x 7.5 x APM) 

determines the total emissions remaining to mitigate off-site. That number then needs 

to multiplied by dollars per ton, in order to determine total dollars required to mitigation 

emissions off-site. The resulting NOx Air Impact Mitigation Fee is as follows: 

[EBE x 2.5] - [EBE x 7.5 x APM] x [Cost of NOx Reductions/ton] 

It is important to note that the percent reduction achieved onsite, results in a greater 

reduction of the NOx fee. While on-site mitigation is not required, the “bigger bang for 

the buck” is achieved with as much on-site mitigation as possible. 

Area and Operational PM10 Fee Formula

The Air Impact Mitigation Fee for PM10 is more straightforward since a project’s PM10 

emissions remain relatively constant over the life of the project. For ease of 

understanding, Figure 4 below demonstrates the relationship between baseline 

emissions, mitigated emissions and half of the baseline emissions.

The required PM10 mitigation is half of the baseline emissions for ten years. In order to 

determine the emissions that are subject to a fee, half of the baseline emissions need to 

be subtracted from the Mitigated Emissions and multiplied by cost of reductions in 

dollars per ton. Thus the resulting PM10 Air Impact Mitigation Fee is calculated as 

follows: 

(Mitigated PM10 emissions – 1⁄2 Baseline PM10 emissions) (Cost of PM10 Reductions) 

Construction Formulas

The Air Impact Mitigation Fees for construction are based on the project’s estimated 

construction equipment emissions, and compared to the statewide fleet average 

emissions. The required information is as follows: 1)a list of construction equipment 

used, 2)the model year, and 3)the hours estimated to be used is compiled, which can 

be determined from the National Construction Estimator or using project-specific 

information if known. Then the model specific emission factors are used to determine 

the actual estimated emissions (designated as AEE). The same hours are multiplied by 

a statewide average fleet emission factor for a particular year, to determine the 

statewide average estimated emissions (designated as SEE). Since the requirement is 

to reduce construction NOx emissions by 20% beyond the statewide average, this is 

determined as follows: 

NOx Construction = (AEE) – [(1.00 x SEE) – (SEE x 0.20)] 

 (AEE) – [1.00SEE – 0.20SEE] 

 (AEE – 0.8SEE) 

PM10 is almost identical, except that the requirement is to reduce construction PM10 

emissions by 45% beyond the statewide average.

VI. EMISSIONS REDUCTIONS FROM RULE 9510 

Both the 2003 PM10 Plan and the Extreme Ozone Attainment Demonstration Plan, 

contain emissions reduction commitments for proposed Rule 9510 of 4.1 tons per day of 

NOx and 5.2 tons per day of PM10 to be achieved by 2010. Those estimates were 

based on assumptions at the time and are commitments that are necessary to assist the 

district in meeting the federal and state PM10 and NOx standards. The methodology 

contained in this section and related attachments demonstrate the draft emission 

reductions for the program. 

As part of determining the emissions reductions, sources that are exempt from the rule 

need to be subtracted out. The District has numerous years of experience in 

commenting on projects subject to CEQA. Based on that experience and the thresholds 

contained in Rule 9510, it is estimated that 15% of all development project emissions 

will be exempt from the provisions that rule. Attachment 2 and Attachment 3 identify the 

growth in emissions for each pollutant for each year, and subtract the emissions that will 

be exempt from the program. Once the emissions subject to the program are identified, 

the required mitigation is applied, which is 33.3% of baseline NOx emissions over ten 

years, 50% of baseline operational PM10 emissions over ten years, 20% of construction 

NOx emissions and 45% of construction PM10 emissions. The reductions achieved onsite were calculated by multiplying the estimated percent of sources opting to use onsite measures, the percent reduction achieved on-site, by the baseline emissions. Offsite reductions were estimated differently. Since grant programs typically rely on project 

life to determine cost effectiveness and emissions reductions, the reduction was divided 

by the average project life for that pollutant’s cost-effectiveness, which is 7 years for 

NOx and 12 years for PM10, and spread out over that number of years. Attachment 2 

and 3 contain the detailed emission reductions calculations. The results of those 

calculations reveal that the program, as currently defined, will result in reductions of 5.4 

tons per day of NOx in 2010 and 5.8 tons per day of PM10 in 2010.

A. ARB performed an EMFAC2002 model run that estimated the growth between 2006 and 2015 (Attachment 1). 

Since this analysis needs growth per year, the current year's missions are subtracted by the previous year's emissions to 

obtain the annual growth. 

Medium-Heavy and Heavy-Heavy Duty emissions have been reduced by 12% to account for through-valley traffic 

B. Rule penetration is estimated to be 85% based on District experience with CEQA projects. 

C. Staff estimate 

D. Determined by multiplying rule penetration of operational emissions, estimated sources to perform on-site reductions, 

average mitigation achieved on-site, and adding the reductions for each year 

E. Determined by subtracting a particular years on-site reduction from the Rule Penetration of Operational Emissions for that year. 

F. Determined by multiplying Remaining Subject Emissions with 250%, and dividing by 7 to account for the average project life of

the estimated emission reduction projects. 

G. The rule requires mitigation of 250% of the first years emissions. That total was then divided by 7 to account for the average

project life of the estimated emission reduction projects. 

On-Site reductions are reduced over time to account for the reduction in mobile emissions

A. Annual Growth in emisions were determined by subtracting one years emissions from the previous year's emissions. 

Emissions' growth in 2011-2014 were determined by taking the difference between 2015 and 2010 and dividing that by 5 years. 

B. The growth in these emissions were taken directly from the emissions inventory, and were reported by road type. Control for 

Regulation VIII is accounted for. 

C. These totals were obtained from ARB. Current year's emissions are subtracted by the previous year's emissions to obtain the annual growth.

D. Cumulative growth was determined by creating a running total of emissions from each year 

E. Rule penetration is estimated to be 85% based on District experience with CEQA projects. 

F. District staff estimate 

G. Determined by multiplying rule penetration of operational emissions, estimated sources to perform on-site reductions, average 

mitigation achieved on-site, and adding the reductions for each year. 

H. Determined by subtracting a particular years on-site reduction from the Rule Penetration of Operational Emissions for that year.

I. Equals 5 x Remaining Subject Emissions That total was then divided by 12 to account for the average project life of the estimated emission reduction projects.

J. Determined by adding On-site Reductions and Off-site Reductions 

K. Total emissions were used for each year, since all construction activity each year is for new development 

L. These emissions were taken from ARB and interpolated based on 2005, 2010, and 2015. 

M. Modeling in the 2003 PM10 indicated that 1.5 tons of NOx are equivalent to 1.0 tons of PM10. 

N. This is a rule requirement 

O. Determined by multiplying Remaining Subject Emissions with 20%, and dividing by 7 to account for the average project life of the 

estimated emission reduction projects. 

P. Determined by multiplying Remaining Subject Emissions with 45%, and dividing by 12 to account for the average project life of the 

estimated emission reduction projects.

A. Annual Growth in emisions were determined by subtracting one years emissions from the previous year's emissions. 

Emissions' growth in 2011-2014 were determined by taking the difference between 2015 and 2010 and dividing that by 5 years. 

B. The growth in these emissions were taken directly from the emissions inventory, and were reported by road type. Control for 

Regulation VIII is accounted for. 

C. These totals were obtained from ARB. Current year's emissions are subtracted by the previous year's emissions to obtain the annual growth.

D. Cumulative growth was determined by creating a running total of emissions from each year 

E. Rule penetration is estimated to be 85% based on District experience with CEQA projects. 

F. District staff estimate 

G. Determined by multiplying rule penetration of operational emissions, estimated sources to perform on-site reductions, average 

mitigation achieved on-site, and adding the reductions for each year. 

H. Determined by subtracting a particular years on-site reduction from the Rule Penetration of Operational Emissions for that year.

I. Equals 5 x Remaining Subject Emissions That total was then divided by 12 to account for the average project life of the estimated emission reduction projects.

J. Determined by adding On-site Reductions and Off-site Reductions 

K. Total emissions were used for each year, since all construction activity each year is for new development 

L. These emissions were taken from ARB and interpolated based on 2005, 2010, and 2015. 

M. Modeling in the 2003 PM10 indicated that 1.5 tons of NOx are equivalent to 1.0 tons of PM10. 

N. This is a rule requirement 

O. Determined by multiplying Remaining Subject Emissions with 20%, and dividing by 7 to account for the average project life of the 

estimated emission reduction projects. 

P. Determined by multiplying Remaining Subject Emissions with 45%, and dividing by 12 to account for the average project life of the 

estimated emission reduction projects.
