Recordkeeping for Auto Refinishers

All auto-body refinishers are required to maintain detailed coating and solvent usage records and material data sheets. Permitted automotive refinishers are requested to maintain charts or lists comparing all coatings and solvents for which limits have been established in Rule 234, Automotive Refinishing Operations to the associated Rule limit. In addition, shops must keep and maintain other logs, records, and material data sheets that record material usage and the VOC content of coating products. Automotive refinishers that are exempt from District permitting due to low coating volume (i.e. less than 1 gallon of coating per day) are required to keep records to maintain the exemption. The exemption form from permitting is available.

Records documenting compliance be kept in the formats provided here, or in equivalent alternative summary formats that provide the information that is required by Rule 234. If the required information is not kept in the manner prescribed by Rule 234, this is a violation of the rule. Record keeping is not an end in itself - operators cannot maintain compliance with Rule 234 limitations without knowing the VOC information that is the subject of the record keeping, and furthermore compliance cannot be demonstrated to the District without these records. This request is made pursuant to Section 500, Monitoring and Records, of Rule 234, Automotive Refinishing Operations, and pursuant to Health and Safety Code Section 42303, Information Disclosure.

Rule 234, Automotive Refinishing Operations, requires operators of facilities subject to the Rule to maintain a current listing of all as-applied VOC containing materials in use at the facility. In addition, current coating technical data sheets, which list the VOC content of each material, are required to be available for review on site. A record of the total facility VOC emissions is also required on a monthly basis. The rule also requires that any person using precoat shall verify compliance with Section 307 by retaining purchase invoices and records of applied volume of precoat on a monthly basis.

To aid complying with Rule 234, we are providing the following three forms:

  • Coating System Line Products List is required for each paint system used and stored on site. This is a listing of all of the paint system components that have VOC containing compounds, which make up your paint system. A list may be provided to you by the manufacturer or distributor of your coating system, and can be used if it has all the information required by Rule 234. The list must reflect current coating use. The form is downloadable as a printable Portable Document Format - PDF - file for handwritten entry, and as a a Microsoft Word file for electronic file entry.

  • Miscellaneous VOC-Containing Products List is required for VOC containing products that are not part a paint “system”, but assist in the refinishing process. Examples of materials that are required to be listed include aerosols that do not have pigments or resins, like strippers, or bulk solvent. The list must reflect current products used. The form is downloadable as a printable PDF file for handwritten entry, and as a Microsoft Word file for electronic file entry.

  • A Monthly Record of VOC Emissions from Automotive Refinishing Operations is required. The monthly log is acceptable and compliant if it includes both paint system and miscellaneous product usages and meets the requirements of Rule 234. The form is downloadable as a printable PDF file for handwritten entry, and as a Microsoft Excel file for electronic file entry. Instructions are provided in a PDF file, and as a Microsoft Word file.

    The "monthly usage log" form was corrected on September 19, 2005. The "precoat/primer" ratio limit has been corrected from 5% to 25%; and the "specialty coating/all coating" ratio limit has been corrected from 25% to 5%.

Technical Data Sheets are required for each VOC containing material used and listed on a Product Lists. Technical data sheets must include the VOC content “As Applied Without Water and Exempt Solvents”, as well as “As Applied With Water and Exempt Solvents”. The VOC content “As Applied Without Water and Exempt Solvents” is required for determining compliance with rule limits. Whereas the VOC content “As Applied With Water and Exempt Solvents” is required to calculate monthly VOC emissions.

All required records must be retained for at least 3 years and are to be made available to the District’s inspector upon request.

If you have questions concerning record keeping requirements for Automotive Refinishing you may contact John Finnell, Senior Engineer at (530) 745-2324. Permitted facilities may request a compliance consultation meeting to informally review your record keeping practices.

Recording Keeping for Emergency Diesel Generators / Engines

Owners / Operators of emergency standby diesel engine generator(s) under Placer County Air Pollution Control District (District) Permit(s) to Operate are currently required to conduct the following recordkeeping. Required recordkeeping activities include a log for the engine operation and a log recording fuel delivery information.

To aid in compliance with the emergency standby diesel engine recordkeeping requirements, either the following District-prepared forms can be used, or alternative equivalent logs that an owner-operator has developed may be used:

  • Diesel Engine Operation Log -- Used to track engine operation, with separate entries for each time the engine is operated. Information includes engine hour meter readings and the reason for operation (e.g. initial engine startup, engine maintenance and testing, and emergency use due to interruption of electrical power). 
        PDF Form Version / WORD Form Version

  • Diesel Engine Summary Monthly Operations -- Used to summarize engine operation over each calendar month of the year. Prepared based on data from the Engine Operation Log.|
        PDF Form Version / WORD Form Version

  • Diesel Engine Fuel Delivery and Purchase Log -- Used to track information on all separate fuel receipts, including delivery date, fuel amount (gallons delivered), and fuel type.
            PDF Form Version / WORD Form Version

These forms may be filled-out by-hand; or alternatively they may be completed electronically. Recordkeeping Advisory Notice (pdf)

Records must be retained for at least thirty-six (36) months after recording. They may be kept either onsite (at a central location or at the engine location), or alternatively may be kept at an offsite central location in California. Records must be made available to the District upon request. Records for the prior twenty-four (24) to thirty-six (36) months must be provided to the District within five (5) working days of a request.

The District will take enforcement action, including monetary penalties, for failure to maintain the required records. Civil penalties of up to $1,000 per day, may accrue for each day that the required records are not maintained. Fees will be charged for re-inspections necessary to verify compliance.

The District requires that these records be kept pursuant to:

  • California Code of Regulations, Title 17, Section 93115, Airborne Toxics Control Measure for Stationary Compression Ignition Engines

  • California Code of Regulations, Title 17, Section 93116, Airborne Toxics Control Measure for Diesel Particulate Matter from Portable Engines Rated at 50 Horsepower and Greater

  • California Health and Safety Code Section 42303, Request for Information

Note that diesel fuel must be either:

  • Certified by the California Air Resources Board as “CARB Diesel Fuel”, or
  • An Alternative Diesel Fuel, including biodiesel, biodiesel blend, Fischer-Tropsch Fuel, emulsion of water in diesel fuel, or any other fuel that meets the Verification Procedures of California Code of Regulations, Title 13, Sections 2700-2710.

Please contact Mr. Michael Sims, District Specialist, at (530) 745-2347, if you have any questions.
