# 2007 Area Sources Emission Inventory Methodology

670-AGRICULTURAL BURNING

I. Purpose

This document describes the Area Source Methodology used to estimate emissions

of carbon monoxide (CO), nitrogen oxides (NO

x 

### ), fine particulate matter less then 10

microns (PM 10 

### ), volatile organic compounds (VOC) and sulfur oxi des (SO

x 

### ), from

Agricultural Burning - Pruning, Agricultural Burnin g - Field Crops and Weed

Abatement in the San Joaquin Valley Air Basin. An area source category is a

collection of similar emission units within a geogr aphic area (ie., a County). An area

source category collectively represent individual s ources that are small and

numerous, and that may not have been inventoried as specific point, mobile, or

biogenic sources. The California Air Resources Boar d (CARB) has grouped these

individual sources with other like sources into are a source categories. These source

categories are grouped in such a way that they can be estimated collectively using

one methodology.



## II. Applicability

The emission calculations from this Area Source Met hodology apply to agricultural

burning of waste and debris identified by the follo wing Category of Emission Source

(CES) codes and Reconciliation Emission Inventory C odes (REIC):

## III. Point Source Reconciliation

Emissions from the area source inventory and point source inventory are reconciled

against each other to prevent double counting. Thi s is done using relationships

created by the California Air Resources Board (CARB ) between the area source

REIC and the point sources’ Standard Industry Class ification (SIC) code and

emissions process Source Category Code (SCC) combin ations. The area sources

in this methodology are not represented within the District’s point source inventory

so reconciliation is not necessary.



## IV. Methodology Description

This methodology estimates emissions from the burni ng of:

A. Pruning: of almond, apple, apricot, avocado, bush berry, ch erry, Christmas

trees, citrus, date, eucalyptus, fig, grape, kiwi, nectarine, nursery plants, olive,

pasture or corral trees, peach, pear, pecan, persim mon, pistachio, plum, pluot,

pomegranate, prune, quince, rose, and walnut. This category also includes670-Agricultural Burning

AgBurningPFW2007.doc Rev by: B. Laudig 

### vineyard materials, orchard removals, and other agr icultural materials such as

attrition.

B. Field Crops : including alfalfa, asparagus, barley stubble, bea ns, corn, cotton,

flower straw, hay, lemon grass, oat stubble, paper hot caps, pea vines,

peanuts, rice stubble, safflower, sugar cane, veget able crops, and wheat

stubble.

C. Weeds : including tulles, tumbleweed, grass, thistle, sta r thistle, dodder weed,

lemon grass, noxious weeds, and weeds growing along ditch bank and canals,

berms, and fence rows.

All open burning, as defined in Rule 4103, requires a valid burn permit and

authorization for the specific event. The District authorizes burning events based on

predicted meteorological conditions and whether the total tonnage to be emitted would

cause a public nuisance, impact smoke sensitive are as, or create or contribute to an

exceedance of an ambient air quality standard. Act ivity data for each authorized burn

events is entered into the District’s Smoke Management System (SMS) database.

Emissions are calculated by multiplying the activit y data by crop specific emission

factors.



## V. Activity Data

Activity data for agricultural burning was obtained from the San Joaquin Valley

Unified Air Pollution Control District’s Smoke Management System (SMS). Activity

data for each burn event includes the following:

A. ACRES : Acres is defined as the area from which the agric ultural waste was

produced, in acres. For example, if prunings came f rom 40 acres of orchard,

40 acres should be entered into the database. The S moke Management

System directs the burn permit holder to enter ACRE S into the Smoke

Management System database in this manner.

B. FUEL LOADING : Fuel loading is a factor that defines the tonnage of burn

material that is generated from an acre of a partic ular crop or tons reported in

the Smoke Management System.

C. TONS : Tons of burn material is calculated by multiplyin g ACRES by FUEL

LOADING. If the burn permit holder reports TONS onl y, TONS are used to

calculate emissions.



## VI. Emission Factors

The Air Resources Board compiled a list of emission factors by crop type based on

AP-42 values, and from a study conducted by B.M. Je nkins (Gaffney, 2000). Fuel

loading values from AP-42 (EPA, 1992) are also asso ciated with each emission670-Agricultural Burning

Page 4 of 21 Rev date: 9 June 2008

AgBurningPFW2007.doc Rev by: B. Laudig 

### factor. Some of the factors and values were adjust ed as needed by the District to

better reflect the conditions in the San Joaquin Va lley. The emission factors can be

found in Appendix B.



## VII. Emissions Calculations

The Smoke Management System allows information rega rding a burn to be reported

in acreage or individual fuel loading capacity if k nown. On an individual crop type

basis, Equation A is used when the actual fuel load ing is not known. Otherwise,

Equation B is used. Then, the emissions from each burn are computed, summed

and totaled by county and year.

Equation A :

## VIII. Temporal Variation

A. Daily

CARB Code 24. 24 hours per day - uniform activity during the day

B. Weekly

CARB Code 7. 7 days per week - uniform activity ev ery day of the week

C. Monthly

Monthly temporal variation for agricultural burning was extracted from the San

Joaquin Valley Unified Air Pollution Control Distri ct’s Smoke Management

System and is presented in Appendix A.



## IX. Spatial Variation

Burn locations are defined by street address in the Smoke Management System

. The street addresses are converted to Latitude and Longitudes, and UTMs.



## X. Growth Factor

Growth factors are developed by either the District ’s Planning Department or CARB

for each EIC. These factors are used to estimate e missions in future years. The

growth factors associated with this emissions categ ory may be obtained from the Air

Quality Analysis Section of the District’s Planning Department.



## XI. Control Level

Control levels are developed by either the District ’s Planning Department or CARB

for each EIC. Control levels are used to estimate emissions reductions in future

years due to implementation of District rules. The se control levels take into account

the effect of control technology, compliance and ex emptions at full implementation of

the rules.

Agricultural burning in the San Joaquin Valley is s ubject to District Rule 4103 (Open

Burning). Control measures specified in Rule 4103 are reflected in the reduction in

amount of material burned. Control levels associat ed with this emissions category670-Agricultural Burning

AgBurningPFW2007.doc Rev by: B. Laudig 

### may be obtained from the Air Quality Analysis Secti on of the District’s Planning

Department.



## XII. CARB Chemical Speciation

CARB has developed organic gas profiles in order to calculate reactive organic

gasses (ROG), volatile organic compounds (VOC) or t otal organic gas (TOG) given

any one of the three values. For each speciation p rofile, the fraction of TOG that is

ROG and VOC is given. The organic gas profile codes can also be used to lookup

associated toxics. CARB’s organic gas speciation p rofile for agricultural burning is

presented in Table 5.

CARB has also developed particulate matter speciati on profiles in order to calculate

particulate matter (PM), particulate matter with a diameter less than or equal to 10

microns (PM 10 

### ) or particulate matter with a diameter less than o r equal to 2.5

microns (PM 2.5 

### ) given any one of the three values. For each spec iation profile, the

fraction of PM that is PM 10 

### and PM 2.5 

### is given. The particulate matter profile codes

can also be used to lookup associated toxics. CARB ’s particulate matter speciation

profile for agricultural burning is presented in Ta ble 6.

Table 6. CARB chemical speciation profile for agri cultural burning.

Fractions Profile Description CARB PM Profile# PM 10 PM 2.5 Orchard Prunings Burning 450 0.9814 0.9252



## XIII. Assessment of Methodology

Emissions calculations are based on amount of mater ial burned. This method is

deemed to be an accurate method for calculating emi ssions, provided that the

characterization of the amount of burn material is accurate.



## XIV. Emissions

The 2007 area source emissions inventory for agricu ltural burning can be found in

Appendix C. Since the District created subcategori es for Waste Burning and

Disposal of Agricultural Burning of Pruning (EIC 67 0-660-0262-0000), Field Crops

(EIC 670-662-0262-0000), and of Weed Abatement (EIC 670-668-0200-0000) in

2006, this inventory is not directly comparable to previously reported inventories. Table 5 . CARB chemical speciation profile for agricultura l burning.

## XV. Revision History

2007. Process rates were updated.

2006. The methodology was reformatted to the new Di strict standard. Process

rates were updated.

2004. This is a new district methodology.



## XVI. Update Schedule

In an effort to provide inventory information to CA RB and other District programs and

maximize limited resources, the District has develo ped an update cycle based on

emissions within the source category as shown in Ta ble 7.

Table 7. Area source update frequency criteria.

Total Emissions

(Tons/Day) Update Cycle

(Years)

<1 4

>1 and <= 2.5 3

>2.5 and <=5 2

>5 1



### Since emissions for these source categories exceed 5 ton per day, these area

source estimates will be updated every year.
