Rule 2530 

(Federally Enforceable Potential to Emit) 

as amended on December 18, 2008 

Analysis of VOC Limits Which Were Not Changed During Rule Amendment 

Various threshold quantities in Rule 2530 were amended on December 18, 2008 to 

incorporate part of the District’s extreme ozone nonattainment requirements. Rule 

2530 amendments changed the various NOx and VOC limits in the rule to correspond to 

the District’s request to be reclassified as an extreme ozone nonattainment area. Rule 

2530 amendments reflect the change to the major source threshold from 25 tons per 

year to 10 tons per year for both NOx and VOC. However, there were certain sections 

pertaining to the VOC limits that were not changed based on the calculations for the 

extreme ozone nonattainment area classification. Strikeout/underline amendments to 

Rule 2530 amendments are included in Attachment A. 

District Rule 2530 was originally based on the January 1, 1995 guidance memorandum 

from John Seitz titled “Option for Limiting the PTE of a Stationary Source under Section 

112 and Title V of the CAA” and the California Example Rule which was attached in the 

Seitz memo. 

EPA is currently evaluating District Rule 2530 and has requested that the District 

provide technical justification for the VOC thresholds that were not adjusted during the 

December 2008 rule amendment. There were only five VOC quantities that were not 

changed from the previous ‘severe’ version of the rule which are in section 5.4.2.3 for 

the de minimus facilities and sections 6.2.1, 6.2.2.1, 6.2.2.2 and 6.2.3 for the Alternative 

Operational Limits. 

As shown below, certain VOC limits in Rule 2530 were not adjusted because these 

VOC limits did not need revision based on our extreme ozone area classification. 

Section 5.4.2.3 – Paint Spray Units

The recordkeeping and reporting requirements of Rule 2530 do not apply to de minimus 

sources. Section 5.4 generally requires that actual emissions be limited to 20% of the 

applicable major source threshold which is 4,000 lb/year for VOC and NOx in extreme 

areas. Section 5.4.2 pertains to paint spraying operations and was not amended based 

on using a conservative VOC limit for paint spraying operations. The calculation was 
SJVAPCD Rule 2530 VOC Analysis November 30, 2009 

based on using a worst case scenario of 6.0 lb-VOC/gallon from EPA’s “Technical 

Support Document for Potential To Emit Guidance Memo1

.” 

Assumptions for Paint Spraying Units: 

• 6.0 lb-VOC/gallon 

• 20% of Extreme Ozone Major Source Threshold is 4,000 lb/year (De Minimus) 

(4,000 lb/year) / (6.0 lb-VOC/gallon) = 667 gallon/year 

Therefore, the 20%-limit is slightly above the 500 gallons level contained in Rule 2530 

for a 12-month period, and therefore assures that such facilities are operating at less 

than 20% of the major source VOC threshold. Additionally, the District’s prohibitory 

coating rules require lower VOC limits than the conservative 6.0 lb/gallon value used 

here, which provides further assurance that these are true de minimus sources with 

emissions below 4000 lb/yr. 

Section 6.2.1 – Gasoline Dispensing Facilities

Section 6.2 outlines the Alternative Operational Limits (AOL) taken from the California 

Example Rule which “allows sources using these limits to go up to 80% of the major 

source threshold [in actual emissions].” 

For Section 6.2.1, the following emissions factors are derived from Appendix A - 

Emission Factors For Gasoline Stations of the Gasoline Service Station Industrywide 

Risk Assessment Guidelines dated December 1997, prepared by CAPCOA under the 

Air Toxic “Hot Spots” Program:2

For Underground Storage Tanks:

0.084 lb/1,000 gal Tank filling loss (98%) 

0.025 lb/1,000 gal Breathing loss (U/G tank) 

0.42 lb/1,000 gal Vehicle fueling loss (95%) 

0.42 lb/1,000 gal Spillage 

0.949 lb/1,000 gal Total VOC losses 

 

To operate below 80% of the extreme major source threshold, the maximum annual 

throughput is: 

(20,000 lb/yr) x (0.8) / (0.949 lb/1,000 gallons) = 16.9 million gallons/yr

For Aboveground Storage Tanks:

 0.42 lb/1,000 gal Tank filling loss (95%) 

 0.053 lb/1,000 gal Breathing loss (A/G tank) 

 0.42 lb/1,000 gal Vehicle fueling loss (95%) 

 0.42 lb/1,000 gal Spillage 

 1.313 lb/1,000 gal Total VOC losses 

To operate below 80% of the extreme major source threshold, the maximum annual 

throughput is: 

(20,000 lb/yr) x (0.8) / (1.313 lb/1,000 gallons) = 12.2 million gallons/yr 

Based on these numbers, we kept the current limit in Rule 2530 section 6.2.1 at 

7,000,000 gallons per year of gasoline dispensed which is well below the allowed AOL. 

Section 6.2.2.1 and Section 6.2.2.2 – Degreasing or Solvent Units

The Technical Support Document for the PTE guidance memo3

 states that the emission 

limits are based on the 10 tpy HAP emissions levels and that these limits ensure 

compliance with the extreme major source VOC threshold with the exception of the 

5,400 gallon amount. The TSD for the PTE memo states: 

The CAPCOA model rule uses the following values as prohibitory rule cutoffs. These 

values are designed to ensure that single HAP emissions are less than about 8 tons per 

year and total HAP emissions are less than 17.5 tons per year. 

-- Non-halogenated solvents: 2200 gallons of any one solvent-containing material (if no 

halogenated solvents), and 5400 gallons of any combination of solvent-containing 

materials 

-- Halogenated solvents used: 1200 gallons of any one solvent-containing material, and 

2900 gallons of any combination of solvent-containing materials. 

[Note: these values would also ensure compliance with major source VOC threshold, 

except for the 5400 gallon amount which would not be protective of the major source 

threshold for extreme ozone nonattainment areas. Hence, adjustments should be made in 

applying these cutoffs in extreme ozone nonattainment areas.] 

The EPA believes that the cutoffs in the CAPCOA model rule would be useful in other 

jurisdictions as well. EPA believes that the great majority of small business sources with

Calculations. April 1998. page 38.
SJVAPCD Rule 2530 VOC Analysis November 30, 2009 

degreasers will fall well below these cutoffs.

Therefore, the limits in these two sections were not changed with the exception of 

revising the combination of solvent-containing materials limit in section 6.2.2.1 from 

5,400 gallon to 2,700 gallons in a 12-month period. As specified by the TSD document, 

the 5,400 gallon level needed to be adjusted to the extreme VOC major source 

threshold and was based on the following assumptions: 

• 6.0 lb-VOC/gallon 

• 80% of Extreme Ozone Major Source Threshold is 16,000 lb/year (AOL) 

(16,000 lb/year) / (6.0 lb-VOC/gallon) = 2,667 gallon/year (rounded to 2,700 gal/yr) 

The amended limit for using a combination of solvent-containing materials assures that 

such facilities are operating at less than 80% of the major source VOC threshold. 

Additionally, the District’s has a prohibitory degreasing rule requiring that nonhalogenated cleaning material be limited to 25 grams-VOC/liter or have a capture and 

control efficiency of the VOC emissions at 85% by weight, which provides further and 

very significant margin of compliance. 

Section 6.2.3 – Paint Spraying Units

The AOL for paint spraying units was not amended based on similar assumption used 

for Section 5.4. 

Assumptions for Paint Spraying Units: 

• 6.0 lb-VOC/gallon 

• 80% of Extreme Ozone Major Source Threshold is 16,000 lb/year (AOL) 

(16,000 lb/year) / (6.0 lb-VOC/gallon) = 2,667 gallon/year 

The District’s allowed limit is above the original 2,100 gallons level in Rule 2530 for a 

12-month period, and therefore assures that such facilities are operating at less than 

80% of the major source VOC threshold. Additionally, the District’s prohibitory coating 

rules require lower VOC limits than the conservative 6.0 lb-VOC/gallon value used here, 

which provides further margin of compliance.

2530 - 1 Proposed Amendments to Rule 2530

RULE 2530 FEDERALLY ENFORCEABLE POTENTIAL TO EMIT (Adopted June 15, 1995; 

Amended April 25, 2002; Amended (date of adoption), but not in effect until (date 

of EPA final approval)) 

1.0 Purpose 

 The purpose of this rule is to restrict the potential to emit of a stationary source so that the 

source may be exempt from the requirements of Rule 2520 (Federally Mandated Operating 

Permits). 

2.0 Applicability 

 This rule shall apply to any stationary source which is a major source of regulated air 

pollutants or of hazardous air pollutants. 

3.0 Definitions 

 All terms shall retain the definitions provided under Rule 2520 unless otherwise defined in 

this section. 

 3.1 12-month period: a period of twelve consecutive months determined on a rolling 

basis with a new 12-month period beginning on the first day of each calendar month. 

 3.2 Actual Emissions: the emissions of a regulated air pollutant from a stationary source 

for every 12-month period. Valid continuous emission monitoring data or source 

test data shall be preferentially used to determine actual emissions. In the absence of 

valid continuous emissions monitoring or source test data, the basis for determining 

actual emissions shall be: throughput of process materials; throughput of materials 

stored; usage of materials; data provided in manufacturer's product specifications; 

material volatile organic compound content reports or laboratory analyses; other 

information required by this rule and applicable District, state, and federal 

regulations; or information requested in writing by the District. All calculations of 

actual emissions shall use EPA, CARB, or District approved methods, including 

emission factors and assumptions. 

 3.3 HAP: an hazardous air pollutant listed in section 112(b) of the federal Clean Air 

Act. 

 3.4 Major Source of Hazardous Air Pollutants: a stationary source with potential to emit 

(including fugitive emissions) 10 tons per year or more of a single HAP, or 25 tons 

per year or more (including fugitive emissions) of a combination of HAPs. 

Emissions from any oil or gas production well (with its associated equipment) and 

emissions from any pipeline compressor station shall not be aggregated with 

emissions from other similar units to determine whether such units or stations are 

major sources of HAPs. 
 PROPOSED December 18, 2008

2530 - 2 Proposed Amendments to Rule 2530

 3.5 Process Statement: an annual report on permitted emission units from an owner or 

operator of a stationary source certifying under penalty of perjury the following: 

throughput of process materials; throughput of materials stored; usage of materials; 

fuel usage; any available continuous emissions monitoring data; hours of operation; 

and any other information required by this rule or requested in writing by the 

District. 

4.0 General Provisions 

 4.1 Any stationary source that is in compliance with the applicable requirements of this 

rule, shall not be considered a major source for the purpose of compliance with 

District Rule 2520. 

 4.2 Provision for Air Pollution Control Equipment: The owner or operator of a 

stationary source may take into account the operation of air pollution control 

equipment on the capacity of the source to emit an air contaminant if the equipment 

is required by Federal, State, or District rules and regulations or permit terms and 

conditions. The owner or operator of the stationary source shall maintain and 

operate such air pollution control equipment in a manner consistent with good air 

pollution control practice for minimizing emissions. This provision shall not apply 

after January 1, 1999 unless such operational limitation is federally enforceable or 

unless the District Board specifically extends this provision and it is submitted to the 

U.S. EPA. Such extension shall be valid unless, and until, the U.S. EPA disapproves 

the extension of this provision. 

 4.3 Within three years of the effective date of District Rule 2520, the District shall 

maintain and make available to the public upon request, for each stationary source 

subject to this rule, information identifying the provisions of this rule applicable to 

the source. 

 4.4 This rule shall not relieve any stationary source from complying with requirements 

pertaining to any otherwise applicable preconstruction permit, or to replace a 

condition or term of any preconstruction permit, or any provision of a 

preconstruction permitting program. This does not preclude issuance of any 

preconstruction permit with conditions or terms necessary to ensure compliance with 

this rule. 

 4.5 Unless the owner or operator has chosen to operate the stationary source under an 

alternative operational limit specified in section 6.2, the owner or operator of a 

stationary source subject to this rule shall obtain any necessary permits prior to 

commencing any physical or operational change or activity which will result in 

actual emissions that exceed the limits specified in section 6.1. 

 4.6 The owner or operator of a stationary source subject to this rule shall obtain any 

necessary permits prior to commencing any physical or operational change or

 5.1 The provisions of this rule shall not apply to a stationary source with valid Part 70 

permits, or a stationary source that has applied for Part 70 permit in accordance with 

timelines required in District Rule 2520. Nothing in this rule shall prevent any 

stationary source which has had a Part 70 permit from qualifying to comply with this 

rule in the future in lieu of maintaining an application for a Part 70 permit or upon 

rescission of a Part 70 permit if the owner or operator demonstrates that the 

stationary source is in compliance with the applicable requirements of this rule. 

 5.2 The provisions of this rule shall not apply to stationary source whose actual 

emissions, throughput, or operation, at any time after the effective date of this rule, 

exceed the limits specified in this rule, provided that the following conditions are 

met:
