Permit Applications

Permit Applications Received

.xlsx file extension is a Microsoft Excel Open XML Spreadsheet (XLSX). You can also open this format in other spreadsheet applications, such as Apple Numbers, Google Docs, and OpenOffice.

The above linked Application Dataset contains a list of applications for permits the District has received and is processing.  Many types of equipment and processes require authorization from the Air Pollution Control District before installing, modifying, or operating (information on the types of operations and businesses that need this authorization can be found here).

There are 3 types of authorizations that are included in the Application Dataset.  Most applications will be for equipment or operations that require an Authority to Construct and Permit to Operate, and will have the phrase “APP” in the Application Record ID. 

Certain types of equipment do not have much impact on air quality, and therefore only require Registration, and will have the phrase “CER” in the Application Record ID.

Larger sources may also require a Federal Operating Permit known as Title V.  Applications concerning Title V permitting have the phrase “APP” in the Application Record ID and will show the type of application in the Title V Permit Action Type column.

The District will accept public comments on any permit application during the review process.  This review process can take from a few days for simple equipment and up to six months for more complicated evaluations.  If you wish to comment on a specific application, please click on the Application Record ID within the dataset to submit your comment(s) via email.  General comments can also be emailed to APCDEngineering@sdcounty.ca.gov.  Additionally, certain applications will require public notifications and formal comment periods.

If you would like to view the application materials, please click the link at the far right of the dataset for the application you are interested in.  Note that if the applicant has requested certain information in the application to be considered trade secret, as allowed by District Rule 175 (available here), there may be a delay in posting the entire application while that request is reviewed.

To aid in understanding the dataset, the following are explanations for some of the information presented:

Column C (Due Date for Application Posting) lists the date by which the District must post the application, pursuant to California Health & Safety Code 40100.6.5(a)(1)(C) (AB423).

Column D (Record Status) shows the current status of the application, as follows:

                Open: The application is under review

                Approved: The permit has been approved and issued

                Cancelled: The application has been canceled

                Denied: The District has denied the application

Note that applications will remain on this dataset until 30 days after they are Approved, Cancelled, or Denied

Column E (Status Date) shows the date the Record Status changed

Column H (Source Category Description) shows the type of equipment that has been applied for.  Note that the alphanumeric code at the start of each line is simply used by the District for billing purposes

Column K (Will Operation Exceed 180 Days) indicates if the application is for short term or long term, and that may affect which Rules and Regulations apply to the equipment

The review process for applications for Authority to Construct and Permit to Operate are presented below, and also available here.

Application Submittal

Within 30 days of receipt, applications are deemed complete or incomplete. Complete applications include all required forms, fees and all information required for the engineer to complete evaluation. 

Authority to Construct

Once an Authority to Construct (ATC) is issued, the applicant can begin construction. The ATC will be valid for one year and can be extended for up to five years in one year increments. The ATC contains the conditions under which the applicant must operate. Deviating from these conditions may be subject to compliance action.

Construction Completion Notice

When the applicant completes construction, and prior to operation, the applicant submits a construction completion notice (CCN). Once the CCN is submitted the ATC serves as the temporary authority to operate the equipment. 

Site Inspection

District staff will inspect the facility/equipment to ensure that they are operating in accordance with the permit conditions. 

Startup Authorization

If the site inspection indicates compliance with ATC conditions and other requirements, the District will issue a Startup Authorization (SA) which authorizes continued operation until a final Permit to Operate (PTO) is issued or until required test results are submitted. The SA lists the conditions under which the applicant must operate until final Permit to Operate is issued.

Permit to Operate

Once the permitting process is complete, the District will issue a permit to operate (PTO). The PTO is valid for one year and must be renewed annually. Similar to the ATC and SA, the PTO lists specific conditions under which the permit holders must operate.
