Source Permitting
Does my facility need a Permit to Operate?
The Northern Nevada Public Health, Air Quality Management Division (AQMD), is tasked with protecting the health and welfare of all residents in Washoe County. The AQMD accomplishes this through the protection of the Environmental Protection Agency (EPA) established, health-based National Ambient Air Quality Standards (NAAQS). One of the primary roles in complying with the NAAQS is the permitting of facilities exceeding certain emissions thresholds.
Pursuant to District Board of Health Regulations Governing Air Quality Management 030.200, the permitting threshold in Washoe County is as follows,
Any facility with the Potential to Emit (PTE) two (2) pounds per day of any criteria pollutants (carbon monoxide, sulfur dioxide, nitrogen dioxide, ozone precursors such as VOCs & nitrogen oxides, particulate matter 10 and 2.5) or one (1) pound per day of any regulated Hazardous Air Pollutant (HAP) shall be required to obtain and hold a Permit to Operate.
In order to determine if your facility will need to apply for a Permit to Operate, you will need to determine your facility-wide PTE to include all emission units, defined as any part of a source that emits, or would have the potential to emit, any regulated pollutant. This can be done by the facility or by hiring a third-party air quality consulting professional.
Typical facilities that require a Permit to Operate include, but are not limited to:
- Gas, oil or solid fuel burning boilers, furnaces or large process ovens
- Commercial fuel storage facilities or gas stations
- Paint and surface coating operations
- Degreasers, dry cleaners or other processes using solvents
- Aggregate, concrete or mineral products processing or mining
- Analytical labs, chemical processing operations, assay labs
- Printing press facilities
- Sawing, grinding or sanding operations
- Remediation soil or water treatment operations
- Industrial facilities which emit air pollutants
- Marijuana cultivation and processing operations
I have determined I need a Permit to Operate, now what?
Prior to construction of your new emissions unit(s), complete and submit an application for Authority to Construct along with any applicable worksheets and potential to emit (PTE)/emissions inventory spreadsheet. An Authority to Construct (ATC) must be obtained prior to construction of any new emission unit in Washoe County. Failure to do so could result in enforcement actions being taken against the facility. Detailed instructions are included with each form. Once a complete application is received by the AQMD (including all required documentation and fee(s)), it will be reviewed within thirty (30) days for administrative completeness (have you provided all required documentation, wet signature from appropriate Responsible Official, facility wide PTE demonstration, etc.). The AQMD will contact you, via email, if additional information is required; otherwise, you may not receive any correspondence. Please be sure all contact information is correct; this can be critical in keeping things moving forward in a timely manner.
Once the application is deemed administratively complete, it will be placed in the queue for processing in the order it was received. Depending on the number of applications in the queue, the complexity of processes associated with the facility, and supporting documentation provided, the ATC can typically be issued within 2 – 4 months. However, the AQMD may take up to 180 days to process. Any lack of information to support the application will result in a longer processing time.
A permit writer will complete a technical review of the application and reach out to the facility for any additional information needed. Once the technical review is complete and the PTE is confirmed to be accurate, an ATC will be issued by mail.
Once the ATC is issued, construction is complete, and the facility is operating at capacity, you will be instructed to contact the AQMD for an initial compliance inspection. Once the AQMD has determined compliance with the ATC, the Permit to Operate can be issued. Prior to issuance, the facility will receive an invoice for permit fees based on anticipated actual throughput.
The facility will be required to submit an annual emissions report for the prior calendar year. Annual reporting requirements are provided on the Permit to Operate.
Pre-Construction Conference
Because of the complexity of the details of some projects, many operators request a preconstruction conference to meet and discuss the details of the proposed project. The AQMD encourages such meetings, especially for more complex sources. Often such a discussion actually speeds up the permit process and results in less confusion for all parties. If you decide to pursue this option further, you should contact one of the WC AQMD staff members under Further Questions and Information.
New Construction and Grading
A Dust Control Permit must be applied for and obtained prior to any new construction which will disturb an area one (1) acre or greater. Visit the Dust Control Program page for more information and instructions for how to apply. The Dust Control Program can be contacted at (775) 784-7200 or AQMDDust@nnph.org.
Forms and Applications
All new and modifying existing sources shall submit an Application for Authority to Construct prior to construction of emissions units. An Applicability Determination Fee shall be included with the application. For payment with a credit card, the applicant will be contacted via email once the application has been received and the invoice is ready for payment.
Prior to issuance of the Authority to Construct, the facility will receive an invoice for the remaining application fees. The remaining application fees are dependent on the source type (i.e., minor, synthetic minor, major), and the applicability determination fee will be subtracted from the total application fee.
- Application for Authority to Construct
A supplemental emissions unit and/or control device worksheet must be submitted with the application for each emissions unit and/or control device. Supplemental worksheets and guidance documents are linked below.
The Fuel Burning Equipment General Source Fee applies to the following applications.
- Fuel Burning Equipment Application - This application shall be used if the facility only contains fuel burning equipment used for comfort (ex., rooftop units, unit heaters, hot water heaters, etc.) and no individual unit exceeds an input rating of one million Btu per hour (1 mmBtu/hr). If the facility contains any other emissions units (ex., diesel engine generator), submit an Application for Authority to Construct instead.
- Internal Combustion Engine (ICE) Application - This application shall only be used if a facility contains a single, standalone internal combustion engine and no other equipment or processes. If the facility contains any other emissions units (ex., natural gas fuel burning, multiple internal combustion engines, etc.), submit an Application for Authority to Construct instead.
