Concrete Products Manufacturing
Concrete products manufacturing and associated equipment emits air
contaminants including particulate matter and toxic air contaminants
and require a permit to operate.
Concrete products manufacturing includes equipment that is used to produce finished concrete products including pre-cast pipe, masonry or similar. Particulate (dust) emissions generated from this equipment are typically controlled by enclosing the process, using wet material or adding water or venting any emissions generated through a dust collector or other fabric filter. Information on permitting a concrete batch plant can be found here.
The information on this page will assist in the completion and submittal of an application for each concrete batch plant. 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.
Plot Plan including stack and/or other release point location(s) and nearby building dimensions
Equipment brochures/process flow diagram
Bag-house/filter specifications and control efficiency (if applicable)
BACT analysis (if applicable)
MSDS for any additives used
The general and equipment specific application forms along with
required attachments must be submitted with each application
The correct fee must be submitted with your application in order for it to be accepted. For this type of equipment, fees are determined based on the time and materials required to conduct the review, so a fee estimate must be obtained from the District prior to submittal. Please note that application fees 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.
Before submitting an application, contact the District (see bottom of page) to obtain an application fee estimate 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 40.
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, you must provide contact information (name and phone number) so that the District can complete payment.
Please note that credit card payments are assessed a transaction fee of 2.2% that is charged by the credit card provider.
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. For concrete products manufacturing, this requirement is typically triggered by PM10. Please note that the 10 pounds per day threshold is based on emissions for the entire process line including fugitive emissions from haul roads and storage piles.
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:
1. A letter disclosing the proprietary information. This can be submitted electronically.
2. A letter for the public record explaining why the information needs to be held as trade secret.
The inclusion of 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.

Select equipment type applications can now be submitted online through Citizen Access. Sign up today to get connected to your applications and permits.
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 concrete products manufacturing applications may
take longer than 60 days to evaluate include: if they require a
mandatory public notice period due to being installed within 1000 feet
of a school, the emissions do not initial pass a health risk
assessment (HRA), or if sufficient supporting information is not
included with the application.
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 at the bottom of this page. Learn more about the rules that govern application processing time.

There are no equipment specific rules for concrete products manufacturing. A complete listing of the District's rules can be found here.
Road Calculation Procedures - This page contains procedures that
should be used to calculate emissions from any of the plant's haul
Mineral Products Industry Calculation Procedures - This page contains procedures that should be used to calculate emissions from equipment such as crushers, screens, conveyers, storage piles and other mineral products industry related emissions associated with the process that occur on-site.
Equipment Calculation Procedures - This page contains procedures
that should be used to calculate emissions from any process heaters or
other fuel combustion.
Use of these calculation procedures will aid in minimizing
application review time and costs. The calculation procedure can be
found at the link at the top of each page and the correct emission
factors 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.
