Air quality notice of construction application – Opportunity to request a public comment period

May 13, 2024 - May 29, 2024, 11:59 p.m.

We propose to approve Dawn Mining’s air quality notice of construction (NOC) application. We will hold a public comment period if one is requested.

Dawn Mining Company submitted a notice of construction application to reduce the volume of liquid in an evaporation pond closure area. The evaporator unit will use a propane burner to speed up evaporation of water in the pond. The facility is located at 5326 Uranium City Road in Ford.

Dawn Mining submitted a separate application to the Washington State Department of Health to review potential emissions of radionuclides.

Documents for review

We determined this proposal satisfies the requirements of Chapter 173-400 WAC. We plan to approve the application. We will hold a public comment period on a draft air permit ("approval order") that includes this change if we receive a written request by May 29, 2024.

To request a public comment period, use one of the ways listed below.

To find out if there are more records for this project, contact our Public Records Office.

A notice of construction permit is required before installing a new source of air pollution or modifying an existing source of air pollution. This permit is sometimes called a "pre-construction permit" because a business must have one before starting construction or operating their business.

A notice of construction air permit limits the amount of air pollutants a business can emit.
