Sand, Rock and Aggregate Plants are operated by the mineral product industry to process sands, rocks, aggregates or recycled concrete and asphalt. The materials processed by these plants are transported to the site or are blasted from an on-site quarry. These plants typically include crushers, screens, conveyors, loadout system, stockpiles, storage bins and haul roads. Crushers used by these plants include jaw crushers, cone crushers and impact crushers. Common screen types include grizzlies, shaking or vibrating screens.
Air contaminant emitted from operations of these sand, rock and aggregate plants include particulate matter and toxic air contaminants. Particulate matter emissions are controlled by water spray, fog spray, surfactant, covered screen and covered conveyor, or by venting crushers, screens and conveyors to baghouses. Emissions from haul roads and material storage areas must also be controlled by watering or other control measure.
Plants are powered by electricity or by diesel engine generators. If the plant is powered by diesel engine generators and the diesel engines have their brake-horsepower rating of 50 bhp or greater, please complete the application forms for non-emergency engines.
The information on this page will assist in the completion and submittal of an application for each gas turbine. Each section of the page contains important information needed to submit an application.

The general and equipment specific
application forms along with required attachments must be submitted
with each application packet.
The correct application fee, as calculated using the fee estimate form tool below, must be submitted along with your application in order for it to be accepted. Additionally, please include the completed estimate form with your application.
Note: The estimate is designed to provide a good starting point for work on most applications; however, certain situations may require specific types of review that require additional fees. The District will review your application and determine if any of these specific considerations apply and will contact you and provide an invoice if additional fees are necessary.
To determine the proper fee, complete the application fee estimate form based on the specifics of your application.
1. "Applicant Site ID/EIF ID” – For
applications at existing facility please provide the Site ID
number.
2. “Reason for Submittal” - Identify the reason
for application submittal from the indicated options:
a. New/
Existing Unpermitted (Do not select for replacements and
modifications)
b. Modification – Includes both physical
modifications of equipment and condition changes.

i. Like
Kind Replacement – review requirements to ensure the replacement meets
the requirements specified in Rule
11*
j. other
*If you are indicating the reason for submittal is
Like Kind Replacement, this will result in a lower fee, but please
ensure you are familiar with the requirements to qualify under this
provision as not all replacements are eligible. If you have a question
regarding applicability of this application type, please contact the
District.
3. “Equipment Type” - Using the dropdown menu, select the equipment type that describes your equipment. When applying for aboveground storage tank permits, there are three choices based on the required vapor controls and tank size– 26A, (tanks with both Phase I & Phase II controls); 26C, (tanks with only Phase I controls, > 550 gallon volume), and 26E, (tanks with 250-550 gallon volume). Ensure you select the proper category to minimize disruptions to application processing.
4. “Applicant DBA” - Enter the company name/DBA of the owner/operator of the equipment
5. “Existing Site” - Select whether the location (site) is new or existing (i.e. has existing permits with the District).
6. “Affected Permit Number” - For changes to existing permits, enter the permit number. For amendments, enter the application number being amended.
7. "Estimate Date” – This is the date the form is filled out.
8. “Equipment Description” – Please enter a brief description of the equipment for which the permit is being applied for.
9. “Special Considerations” - Complete any
of the special consideration drop downs that apply. Note that the form
for rim seal replacements does not require indicating number of each
type of equipment and only requires selecting the fee schedule (25B)
and number of units (tanks undergoing rim seal replacement).
a. "Number of Crushing Systems", "Number
of Screening Systems", "Number of Loadouts".
Indicate the number of each type of equipment that is being proposed
or affected by the application. When determining the quantity, it is
per processing line (i.e. primary crushing vs. secondary crushing,
primary screening vs. secondary screening). For example, a new
facility installing 1 primary crusher and 2 secondary crushers in
parallel would indicate "2" in the crusher box. A
modification to an existing facility adding a tertiary crusher to this
same facility would indicate "1" in the crusher box..
b. "Outstanding Permit Fees." If your permit was
previously retired for non-payment, you may owe back fees. Indicate
yes in this box, and contact the District to determine what total
amount is owed. This must be paid prior to apply to reactive your
permit.
c. "Split Payment". The District has
a split payment option. This allows the application to be paid in two
installments. If you wish to request this option, indicate yes and the
total fee will be divided in two, plus an additional processing fee is
paid with the first application.
d. "HRA Fee not
applicable..." District Rule
1200 requires that an HRA be conducted for any project that
results in an increase in Toxic Air Contaminants. The estimate sheet
assumes that most applications require this fee; however, certain
applications may not increase emissions or a project may consist of
multiple applications where only one fee is required. If either of
these is the case for your application, use this box to remove the HRA
fee, but note that if this fee is required an invoice will be issued
for the additional amount.
The specific fees that must be included are determined by District Rule 40 and can include fixed fees and/or time and material (T&M) based fees. Please note that T&M based fees are estimates and can vary based on the amount of work necessary to complete the review of the application. Additionally, review of certain requirements, including Health Risk Assessments (HRA), New Source Review (NSR), California Environmental Quality Act (CEQA), and others are also assessed on a Time & Material basis.
Note for Multiple Applications - If you are submitting multiple applications simultaneously, a single fee estimate sheet can be used if all equipment is within the same fee schedule and you are applying for multiple permits. However, note that a single application record will be created for each individual application.
If you are submitting multiple applications simultaneously and wish to take advantage of the multiple identical equipment lower fee provisions of Rule 40, complete an estimate form for the first unit, and then a separate form for the subsequent units, with the reason for submittal as “Additional Identical Unit, Applying Same Time”.
NOTE: The fees listed in this estimate are intended to be the deposit necessary to begin work on your application. In most cases, fees will be accurate; however, some fees are estimates of time & material based fees and the final fee may be more or less than the estimated amount. If additional fees are owed, you will be invoiced for these fees and if any fees are remaining after approval, these will be refunded. Work records are kept for purposes of establishing time and material based fees.
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.
Sign up for Citizen Access to get up to date information on the status of your application.

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 sand, rock and aggregate processing, this is typically triggered by PM10. Please note that the 10 pound per day threshold is based on emissions from the entire process line, not just a single emission point and includes fugitive sources.
If you have questions or need assistance reference the BACT Guidance Document or the contact information on the assistance tab. 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.
This equipment is subject to Federal
New Source Performance Standard (NSPS) subpart OOO. Requirements
of this rule depend on this size of the equipment, construction date
