Narrative Summary of New Rule or Rule Changes: New Rule Amended Rules 

RULE 102, DEFINITIONS: The District added and modified several solvent-related and surface-coating definitions that 

are used in various parts of the rulebook. The definition of reactive organic compound was updated to include most of the 

exempt compounds listed in 40 CFR 50.100(s) and an exempt compound definition was added. RULE 202, 

EXEMPTIONS TO RULE 201: The main change updated the test method for low ROC-content solvents to refer to the 

SCAQMD Method 313-91. RULE 321, SOLVENT CLEANING MACHINES AND SOLVENT CLEANING: A slight 

amendment to exemption B.6 was made to clarify that the solvent cleaning machine requirements of Rule 321 apply when 

facilities subject to an operation-specific rule are using a degreaser.1 RULE 330, SURFACE COATING OF METAL 

PARTS AND PRODUCTS: Added Rule 321-type exemptions, definitions, and general solvent cleaning, recordkeeping, 

reporting, source testing, and compliance provisions. RULE 337, SURFACE COATING OF AEROSPACE VEHICLES 

AND COMPONENTS: In addition to the changes outlined for Rule 330, we added: 1) adhesive and sealant provisions; 

and 2) coating categories and limits from a USEPA Control Techniques Guideline document and a federal regulation for 

the source category. The District also lowered the stripper ROC limit from 400 to 300 grams per liter in response to 

suggestions by the ARB and the USEPA. RULE 349, POLYESTER RESIN OPERATIONS: The changes outlined for 

Rule 330 were included in PAR 349. Lower polyester resin material monomer contents limits and a higher add-on control 

equipment overall efficiency limit were also added. These new provisions have a 24-month phase-in period to allow for 

product sale-through and available stock depletion. Lastly, staff made minor changes to the rule’s Attachment A, “Static 

Method for Determination of Volatile Emissions from Polyester and Vinyl Ester Resins.” RULE 353, ADHESIVES AND 

SEALANTS: The District amended the rule to include Rule 321-type provisions like in the other rules. We added 

application equipment requirements and stripper use provisions. The ROC-content limits on several products were also 

reduced.

 On Sept. 29, 2011, EPA approved the version of Rule 321 adopted on Sept. 20, 2010 (76 FR 60376). Due to the minor nature of the 

Rule 321 revisions on June 21, 2012, the responses shown in Sections II - VI apply only to the recently amended Rules 330, 337, 349, 

and 353. The District will address the EPA concerns with Rule 321, as outlined in the July 2011 Technical Support Document, the 

next time Rule 321 is amended. This amendment is slated for the 2013 - 2015 timeframe.

VI. IMPACT ON AIR QUALITY PLAN 

 No Impact Impacts RFP Impacts attainment 

Discussion: The difference between the ROC emission reduction in the 2010 plan and the rulemaking estimate is less 

than five pounds per day. With the 192 tons per year of ROC emission reduction anticipated from the Rule 321 

amendments adopted in Sept. 2010, the five pounds per day shortage is insignificant.

SOURCE CHARACTERISTICS 

This assessment is for reactive organic compound (ROC) emission reductions due to the new and 

modified solvent cleaning requirements that were added to the following rules on June 21, 2012: 

Rule 330, Surface Coating of Metal Parts and Products,

Rule 337, Surface Coating of Aerospace Vehicles and Components 

Rule 349, Polyester Resin Operations, and

Rule 353, Adhesives and Sealants 

Solvent cleaning includes wipe cleaning (handwiping), solvent flushing operations, and coating 

application equipment cleaning. Generally, before applying a coating, an operator will wipe 

clean the surfaces using a solvent-laden rag. During the subsequent cleanup activities, overspray 

is removed by wipe cleaning and the spray application equipment is cleaned using a solvent. 

METHODS

The primary way ROC emissions are reduced from solvent cleaning is by the use of low-ROC 

content solvents (typically 25 grams per liter or less). 

Emission reductions are assessed using 2009 base year data with the application of controlrelated factors (e.g., percent exempt, compliance efficiency, and the maximum density of 

complying solvents). 

 

1

 Although Rule 337, Surface Coating of Aerospace Vehicles and Components, was part of the rulemaking project, 

no emission reductions were assessed from these operations. Staff was unable to assess emission reductions from 

such operations due to the lack of baseline data and there being no significant decrease in the ROC-content for 

solvents used in cleaning activities. 
Santa Barbara County APCD Page 2 July 11, 2012 

Base year 2009 data is comprised of data from two groups: “point source” and “area source.”

Point sources using solvents subject to a Santa Barbara County Air Pollution Control District 

(District) Permit to Operate report their solvent use to the District. Thus, the District’s point 

source data is based on recordkeeping and reporting performed by the sources to comply with 

their permit conditions. Area sources are generally non-permitted sources of emissions. 

The area source inventory data is from the California Air Resources Board (ARB) California 

Emissions Inventory Development and Reporting System (CEIDARS).1

 The District provides 

ARB with its point source inventory. The ARB subtracts the District’s point source data from 

the area source emission inventory to avoid any double-counting of emissions. 

The 2009 base year emission and reduction estimates were projected (grown) to 2020 and 2030 

using activity factors (also known as activity indicators) for each SCC-Standard Industrial Code 

(SIC) combination and for each area source (EIC number) category.2

 The annual activity is 

uniform throughout the year. 

The following provides details on the different equations used to calculate emission reductions 

and projected (grown) figures. 

Equation [1] 

The general equation for calculating emission reductions is: 

ER = (Current Emissions – Emissions After Control) * Compliance Factor [1] 

Where:

 ER = Emission Reduction 

 Current Emissions = The ROC emissions from the 2009 inventory 

 Emissions After Control = The ROC emissions with compliance with the revised rule 

requirements 

 Compliance Factor = 80 percent (EPA/ARB default value) 

Equation [2] 

The equation for calculating the Emissions After Control for the solvent replacement control 

technique for a point source is: 

 

1

 Additional details on how the ARB develops CEIDARS data for the handwiping category may be obtained from 

the following web pages: www.arb.ca.gov/ei/areasrc/onehtm/one3-2.htm and 

www.arb.ca.gov/ei/areasrc/fullpdf/full3-2.pdf. The general public does not have access to CEIDARS reports. 

However, District staff may be requested to assist in generating such a report. 

2

 The District used data from the 2010 Clean Air Plan, Table 6-7, coupled with mathematical interpolation 

techniques to derive the activity indicators for growing data from 2009, to 2020 and 2030. An Excel worksheet 

documenting these calculations is available from the District upon request. 
Santa Barbara County APCD Page 3 July 11, 2012 

Emissions After Control (lbs/yr) = Current Thruput (gals/yr) * 1.5 Vol. Ratio * Density (lbs/gal) [2] 

Where:

 Emissions After Control = The ROC emissions with compliance with the revised rule 

requirements (lbs/yr) 

 Current Thruput = The 2009 inventory ROC-solvent net usage rate (gals/yr)1

 1.5 Vol. Ratio = The ratio of the volume of replacement material to ROC 

solvent2

 Density = The maximum allowable ROC density per the rule (lbs/gal) 

Equation [3] 

The equation for calculating the Emissions After Control for the solvent replacement control 

technique for area sources in the EICs 23023090000000, 25029282020000, and 

41040350180000 categories is: 

Emissions After Control (TPD) = [Current Emissions (TPD) * Exempt Eq (%)/100] + {[Current Thruput 

(gals/day) * 1.5 Vol. Ratio * Density (lbs/gal) * 1 ton/2000 lbs]*[1 – Exempt Eq (%)/100]} [3] 

Where:

 Emissions After Control = The ROC emissions with compliance with the revised rule 

requirements (TPD)3

 Current Emissions = The ROC emissions from the 2009 inventory (TPD) 

 Current Thruput = The 2009 inventory ROC-solvent net usage rate (gals/yr)4

 1.5 Vol. Ratio = The ratio of the volume of replacement aqueous material to 

ROC solvent 

 Density = The maximum allowable ROC density per the rule (lbs/gal) 

 Exempt Eq = Percent of equipment that is exempt from the requirements (%) 

 

1

 When throughput data was unavailable, staff calculated the figure using ROC emission and solvent ROC density 

data. For example: (X tons/day) * (260 day/year) * (2000 lbs/ton) * (1/density lbs/gal) = Y gals/year. 2

 Per the South Coast AQMD Staff Report for Proposed Amended Rule 1122 – Solvent Degreasers, August 8, 2001, 

pages 14, 15, and 23. 

3

 The conversion from tons per day (TPD) to tons per year (TPY) is achieved by multiplying the TPD figure by 260 

days per year for Rules 330 and 349, and 365 days per year for Rule 353. 

4

 When throughput data was unavailable, staff calculated the figure using ROC emission and solvent ROC density 

data. For example: (X tons/day) * (260 day/year) * (2000 lbs/ton) * (1/density lbs/gal) = Y gals/year. 
Santa Barbara County APCD Page 4 July 11, 2012 

Equation [4] 

The equation for projecting future emissions data is: 

Future Data = Emission Info * Activity Factor [4] 

Where:

 Future Data = Emissions (TPD or TPY) or emission reductions (TPD or TPY) 

for CY 2020 or 20301

 Emissions Info = 2009 base year emissions (TPD or TPY) or emission 

reductions (TPD or TPY) with compliance with the rule 

requirements 

 Activity Factor = The ratio of future year activity to base year activity; used to 

grow (increase or decrease) the 2009 base year data to CY 

2020 or 2030 

ASSUMPTIONS 

1. The point source and area source inventory data shown in Attachments A and B are 

correct. 

2. The point and area sources identified in Attachments A and B will be subject to Rules 

330, 337, 349, and 353.

3. That sources subject to the rules will use solvents having the maximum ROC content 

allowed by the rule. 

4. The activity indicators shown in Attachments A and B are correct. 

6. Solvent densities shown Attachments A and B are correct. 

7. It is reasonable to convert from tons per year (TPY) to tons per day (TPD) and from tons 

per day to tons per year by using a 260 days per year operating schedule for Rules 330, 

and 349 and a 365 days per year operating schedule for Rule 353.

SAMPLE CALCULATIONS 

1. Below is an example calculation of the ROC emission reductions from a point source

solvent cleaning operation subject to the solvent replacement technique where the new 

maximum solvent ROC limit is 25 grams per liter (0.2086 lbs/gal):2

Using equation [2] and knowing the current throughput is 36.64 gallons per year: 

Emissions After Control (lbs/yr) = 75 gals/yr * 1.5 Vol. Ratio * 0.2086 lbs/gal

Emissions After Control (lbs/yr) = 23.468 lbs/yr 

 

1

 The units depend on the units used for the “Emissions Info” figure: TPD or TPY. 2

 This example uses the FID 02031, DID 108710, data. 
Santa Barbara County APCD Page 5 July 11, 2012 

Using equation [1] and knowing the current emission rate is 535.35 lbs/yr: 

ER = (535.35 lbs/yr – 23.468 lbs/yr) * 0.8 

ER = 409.51 lbs/yr or 0.2048 TPY

Using equation [4] to grow the 2009 base year emission reductions to 2020: 

Future Data = 0.2048 TPY * 0.9999 

CY 2020 ER = 0.2047 TPY or 0.0008 TPD 

2. Below is an example calculation of the ROC emission reductions from an area source in 

due to solvent replacement where the new maximum allowable solvent ROC limit will be 

25 grams per liter (0.2086 lbs/gal):1

Using equation [3] and knowing the current solvent cleaning emission rate is 0.0293 TPD , the 

throughput is 10.809 gallons per day, and 10 percent of the solvent cleaning is exempt: 

Emissions After Control (TPD) = [0.0293 (TPD) * 10/100] + {[10.809 (gals/day) * 1.5 Vol. 

Ratio * 0.2086 (lbs/gal) * 1 ton/2000 lbs]*[1 - 10/100]} 

Emissions After Control (TPD) = 0.0045 TPD 

Using equation [1]: 

ER = (0.0293 TPD - 0.0045 TPD) * 0.8 

ER = 0.0199 TPD or 5.18 TPY 

Using equation [4] to grow the 2009 base year emission reductions to 2020: 

Future Data = 0.0199 TPD * 0.9999 

CY 2020 ER = 0.0199 TPD or 5.18 TPY
