Membrane Manufacturing

Membrane Filter

The membrane manufacturing process emits air contaminants and requires a permit to operate. The following information will assist you in submitting an application for this type of operation. Each section of the page contains important information that you will need in order to process your application. 

Application Forms

The District collects information about your processes by asking you to complete application forms. These forms tell us about your operation and allow us to permit your process. It is very important that these forms are filled out completely and accurately. Errors and missing information may lead to delayed processing time and potentially additional charges if revisions are required. Please carefully review and complete the forms and contact the District with any questions.

Fees

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.

How to Pay

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.

Best Available Control Technology

If you plan to emit more than 10 pounds per day of particulate matter (PM10), oxides of nitrogen (NOx), volatile organic compounds (VOC) or oxides of sulfur (SOx) please prepare a best available control technology (BACT) analysis. The District has a BACT guide to assist you with the analysis. If you have questions or need assistance reference the contact information at the bottom of this page.

Toxic Air Contaminants

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.

Trade Secret

The District has rules that regulate 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 presence of proprietary materials can significantly delay permit applications. In an effort to expedite your permit application process it is recommended that you contact the manufacturer of any materials that you use containing proprietary materials and prepare the required letters prior to your application submittal. 

AB3205

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.
