9/28/2017 - Permitting Emission Unit Advisory


Vehicle Loading as Emission Units for Exporting Minerals

This Stationary Source Permitting Advisory is intended for all stationary sources in Clark County, NV, that are required to obtain and/or maintain an air quality permit for processing minerals. This advisory applies to all stationary sources that will submit an application to the Clark County Department of Air Quality (DAQ) for a new, renewed, or modified operation.

DAQ has determined that the activity of loading minerals into vehicles (e.g., trucks, railcars, etc.) after being processed at a stationary source will be treated as an emission unit for the purposes of stationary source permitting. Because DAQ has treated the similar activity of transporting raw materials to a mineral processing plant as an emission unit, the department has concluded that the activity of loading vehicles transporting materials away from a mineral processing plant is a comparable emission unit.

Effective immediately, DAQ will require applicants to list all activities associated with loading vehicles with minerals as emission units. Applicants must include these activities as emission units, along with all relevant information, in the next application submittal to modify mineral processing at a stationary source or to renew a stationary source permit.

If you have any questions regarding this change, or need more information, please contact our Small Business Assistance Program staff at (702) 455-5942.

Frequently Asked Questions (FAQs)

What is a stationary source and when is a permit required?

A stationary source is any building, structure, facility, or installation that emits or may emit any regulated air pollutant. A stationary source that has a potential to emit any regulated air pollutant that is equal to or greater than the emission applicability thresholds listed in the Clark County Air Quality Regulations (AQRs) is required to obtain an air quality permit

. What is a stationary source permit application?

A stationary source permit application is used to obtain, renew, or revise an air quality permit. Permits are issued to stationary sources in Clark County, NV. AQR Sections 12.0–12.5 list the requirements for obtaining a stationary source permit.

 As a stationary source that processes minerals, what must I do?

Stationary sources submitting applications to DAQ for obtaining, renewing, or revising an air quality permit must include all vehicle loading activities as emission units. The information submitted for vehicle loading should include, but not be limited to, a description of the activity, the amount of throughput that can be achieved, the amount of throughput that is being proposed, and the amount of air emissions associated with the activity. 

Where can I get a copy of the permit application forms?

DAQ's website contains applications, worksheets, and all other department forms required to obtain a stationary source permit.
