Where: VOC content = grams of VOC per liter of coating
Public Notice Draft / Rule 67.0 -21- 

Ws = weight of all volatiles, in grams .

Ww = weight of water, in grams

Wec = weight of exempt compounds, in grams 

Vm = volume of coating, in liters 

Vw = volume of water, in liters

Vec = volume of exempt compounds, in liters

(ii) For low-solids coatings, determine the VOC content in units of grams of 

VOC per liter of coating thinned to the manufacturer’s maximum recommendation, 

including the volume of any water and exempt compounds. Determine the VOC 

content using the following equation:

VOC Contentls = (Ws - Ww - Wec) / (Vm)

Where: VOC contentls = the VOC content of a low solids coating in grams

of VOC per liter of coating

 Ws = weight of all volatiles, in grams

 Ww = weight of water, in grams

 Wec = weight of exempt compounds, in grams 

 Vm = volume of coating, in liters

is U.S. EPA Method 24, incorporated by reference in Subsection (f)(2) (iv)(K), 

except as provided in Subsections (f)(2)(ii) and (f)(2)(iii). An alternative method to 

determine the VOC content of coatings is SCAQMD Method 304-91 (Revised 

February 1996), incorporated by reference in Subsection (f)(2)(iv)(L). The exempt 

compounds content shall be determined by South Coast Air Quality Management 

District (SCAQMD) Method 303-91 (Revised August 1996), incorporated by 

reference in Subsection (f)(2)(iv)(J). To determine the VOC content of a coating, the 

manufacturer may use U.S. EPA Method 24, or an alternative method as provided in 

Subsection (f)(2)(ii), formulation data, or any other reasonable means for predicting 

that the coating has been formulated as intended (e.g. quality assurance checks, 

recordkeeping). However, if there are any inconsistencies between the results of a 

Method 24 test and any other means for determining VOC content, the Method 24 

test results will govern, except when an alternative method is approved as specified 

in Subsection (f)(2)(ii). The Air Pollution Control Officer may require the manufacturer to conduct a Method 24 analysis. 

 (ii) Alternative Test Method: Other test methods demonstrated to provide 

results that are acceptable for purposes of determining compliance with Subsection

coating that is below the compliance limit in Table 1I. The demonstration shall use the 

equation specified in Section A.1 of this Appendix for projecting the actual emissions 

and allowable emissions during each compliance period. The demonstration shall also 

include all VOC content levels and projected volume sold within the State for each 

coating listed in the Program during each compliance period. The requested data can 

be summarized in a matrix form. 

A.3.4 A specification of the compliance period(s) and applicable reporting dates. The length 

of the compliance period shall not be more than one year or less than six months. 

A.3.5 An identification and description of all records to be made available to the Executive 

Officer upon request, if different than those identified under Section A.3.6. 

A.3.6 An identification and description of specific records to be used in calculating emissions 

for the Program and subsequent reporting, and a detailed explanation as to how those 
Public Notice Draft / Rule 67.0 -31- 

records will be used by the manufacturer to verify compliance with the averaging 

requirements. 

A.3.7 A statement, signed by a responsible party for the manufacturer, that all information 

submitted is true and correct, and that records will be made available to the Executive 

Officer upon request. 

A.4 REPORTING REQUIREMENTS

A.4.1 For every single compliance period, the manufacturer shall submit a mid-term report 

listing all coatings subject to averaging during the first half of the compliance period, 

detailed analysis of the actual and allowable emissions at the end of the mid-term, and 

an explanation as to how the manufacturer intends to achieve compliance by the end of 

the compliance period. The report shall be signed by the responsible party for the 

manufacturer, attesting that all information submitted is true and correct. The mid-term 

report shall be submitted within 45 days after the midway date of the compliance 

period. A manufacturer may request, in writing, an extension of up to 15 days for 

submittal of the mid-term report. 

A.4.2 Within 60 days after the end of the compliance period or upon termination of the 

Program, whichever is sooner, the manufacturer shall submit to the Executive Officer a 

report listing all coatings subject to averaging during the compliance period, providing 

a detailed demonstration of the balance between the actual and allowable emissions for 

the compliance period, any identification and description of specific records used by the 

manufacturer to verify compliance with the averaging requirement, and any other 

information requested by the Executive Officer to determine whether the manufacturer 

complied with the averaging requirements over the specified compliance period. The 

report shall be signed by the responsible party for the manufacturer, attesting that all 

information submitted is true and correct, and that records will be made available to the 

Executive Officer upon request. A manufacturer may request, in writing, an extension 

of up to 30 days for submittal of the final report.

A.5 RENEWAL OF A PROGRAM

 A Program automatically expires at the end of the compliance period. The manufacturer may request a renewal of the Program by submitting a renewal request that shall 

include an updated Program, meeting all applicable Program requirements. The 

renewal request will be considered conditionally approved until the Executive Officer 

makes a final decision to deny or approve the renewal request based on a determination 

of whether the manufacturer is likely to comply with the averaging requirements. The 

Executive Officer shall base such determination on all available information, including 

but not limited to, the mid-term and the final reports of the preceding compliance 

period. The Executive Officer shall make a decision to deny or approve a renewal 

request no later than 45 days from the date of the final report submittal, unless the 

manufacturer and the Executive Officer agree to an extension of time for the Executive 

Officer to take action on the renewal request. 
Public Notice Draft / Rule 67.0 -32- 

A.6 MODIFICATION OF A PROGRAM

 A manufacturer may request a modification of the Program at any time prior to the end 

of the compliance period. The Executive Officer shall take action to approve or 

disapprove the modification request no longer than 45 days from the date of its 

submittal. No modification of the compliance period shall be allowed. A Program 

need not be modified to specify additional coatings to be averaged that are below the 

applicable VOC limits. 

A.7 TERMINATION OF A PROGRAM

A.7.1 A manufacturer may terminate its Program at any time by filing a written notification 

to the Executive Officer. The filing date shall be considered the effective date of the 

termination, and all other provisions of this rule including the VOC limits shall 

immediately thereafter apply. The manufacturer shall also submit a final report 60 

days after the termination date. Any exceedance of the actual emissions over the 

allowable emissions over the period that the Program was in effect shall constitute a 

separate violation for each day of the entire compliance period. 

A.7.2 The Executive Officer may terminate a Program if any of the following circumstances 

occur: 

A.7.2.1 The manufacturer violates the requirements of the approved Program, and at the end of 

the compliance period, the actual emissions exceed the allowable emissions. 

A.7.2.2 The manufacturer demonstrates a recurring pattern of violations and has consistently 

failed to take the necessary steps to correct those violations. 

A.8 CHANGE IN VOC LIMITS

 If the VOC limits of a coating listed in the Program are amended such that its effective 

date is less than one year from the date of adoption, the affected manufacturer may 

base its averaging on the prior limits of that coating until the end of the compliance 

period immediately following the date of adoption. 

A.9 LABELING

 Each container of any coating that is included in averaging program, and that exceeds 

the applicable VOC limit in the table in Section 301 shall display the following 

statement: “This product is subject to architectural coatings averaging provisions in 

California.” A symbol specified by the Executive Officer may be used as a substitute. 

A.10 VIOLATIONS

 The exceedance of the allowable emissions for any compliance period shall constitute a 

separate violation for each day of the compliance period. However, any violation of 

the requirements of the Averaging Provision of this rule, which the violator can 

demonstrate, to the Executive Officer, did not cause or allow the emission of an air 
Public Notice Draft / Rule 67.0 -33- 

contaminant and was not the result of negligent or knowing activity may be considered 

a minor violation.

A.11 SUNSET OF AVERAGING PROVISION

 The averaging provision set forth in Appendix A shall cease to be effective on 

January 1, 2005, after which averaging will no longer be allowed.
