Coffee roasting emits air contaminants including oxides of nitrogen, carbon monoxide, volatile organic compounds, oxides of sulfur, particulate matter. District Rules require a permit for any coffee roaster with a maximum capacity above 11 pounds (5 kg).
Emissions from coffee roasting are typically controlled using a combination of a cyclone and either an afterburner or wet-scrubber. Odor and associated nuisance is known to be a potential concern from the roasting of coffee.
The information on this page will assist in the completion and submittal of an application for a coffee roaster. Each section of the page contains important information needed to submit an application.
Application forms tell us about your operation and allow us to permit your process. Accurate and complete information decreases processing time and helps avoid additional charges for unnecessary revisions. Please carefully review and complete the following forms. Also listed below are required attachments that need to be submitted with the application. You may contact the District with any questions.
The general and equipment specific application forms along with
required attachments must be submitted with each application
The correct fee, as shown in the table(s) below, must be submitted
with your application in order for it to be accepted. Please
note that the fees listed in these tables are estimated and the final
fee may be more or less than this amount based on time and materials
spent processing the application. The District maintains work records
for this purpose.
If you are unsure of the correct fee contact the District (see
Assistance tab) to obtain an application fee estimate to confirm the
fees required for application submittal. Please note that an
additional fee may also apply depending on the method of payment. A
breakdown of how the application fee(s) are determined can be seen here. Additional
information can be found in District Rule
These fees may be paid by check payable to "Air Pollution Control District" or by credit card (Visa, MasterCard, Discover, and American Express).
If you choose to email or fax your application and intend on paying with a credit card, ensure that you have obtained your fee estimate and have it in hand, and then after submitting the application, you must contact the District over the phone at (858)586-2600 to provide payment information.
Please note that credit card payments are assessed a transaction fee of 2.19% that is charged by the credit card provider.
The District will act on complete applications as soon as possible but at most within 180 days. The engineer assigned to your application will review it and contact you within 30 days of receipt to confirm that it is complete or request additional information. Typically permits are issued in about 60 days. More complex processes will take longer. Common reasons that applications may take longer than 60 days to evaluate include: the project is a complex project specifically at a major source, if the project requires a mandatory public notice period due to being installed within 1000 feet of a school or triggering the requirement for a air quality impact analysis (AQIA), if they do not initially pass a health risk assessment (HRA) or AQIA, if BACT is not proposed or complete BACT analysis is not submitted or for major sources if actual emission data is not included.
Ensuring your application is complete is the best way to reduce processing time. Complete emissions data is the most important factor in minimizing application processing time and iterative information requests. If you have any questions about what information is required, please contact the District using the information on the Assistance tab.

If a piece of equipment or a process emits more than 10 pounds per day of particulate matter (PM10), oxides of nitrogen (NOx), volatile organic compounds (VOC) or oxides of sulfur (SOx), the application must include a best available control technology (BACT) analysis. The District has a BACT guide to assist with the analysis. If you have questions or need assistance reference the contact information at the bottom of this page. Please review District Rules 20.1 and 20.2.
District Rule 1200 applies to any new, relocated, or modified emission unit which may increase emissions of one or more toxic air contaminant(s). The proposed project must comply with Rule 1200. Proposed equipment may require toxics best available control technology (TBACT) depending on the project. Please review District Rule 1200 for further details.
District rules address how information that is submitted to the District is managed. District Regulation IX contains District Rules 176 and 177. Please refer directly to these rules when submitting trade secret information. However, be aware that you will need to submit:
Applications submitted with incomplete material composition data due to failure to include proprietary information can significantly delay permit applications. In an effort to expedite the permit application process it is recommended that you contact the manufacturer or vendor of any proprietary materials that are used in the process and prepare the required letters as part of your application submittal.
In 1989, the California state legislature passed a law, AB 3205, designed to protect schoolchildren from hazardous air contaminants. The law, as currently written, requires the District to notify parents of schoolchildren, neighboring businesses and residents of all new or modified equipment that emits any hazardous air contaminant into the air which will be installed within 1,000 feet of a school site. The law also requires the District to consider any comments before authorizing construction. Please review your proposed location. If a school property boundary is located within 1,000 feet of the proposed emissions point, the AB3205 process will be initiated. This process requires a 30 day public comment period and the overall process will delay projects by at least six weeks.
Coffee Roasters are not subject to any of these rules.
Procedures - This page contains procedures to be used for
calculating emissions from this equipment that should be submitted
with each application.
Use of these calculation procedures will aid in minimizing application review time and costs. The correct emission factors should be selected from the list based on equipment. If available, manufacturer provided equipment specific emission data or source test results should be utilized before using default emission factors. Sources of all emission data used must be included as attachments to the application.
AP-42 is an alternative compilation of emission factors and calculation procedures prepared by the EPA that may be utilized by the District in some situations for some equipment types.
