This is a public notice of an air quality permit. We will hold a public comment period if one is requested.
Imerys Inc., located at 16419 Road 10.5 NW in Quincy, submitted an air quality Notice of Construction application to install a 12 MMBTU/hr natural gas preheater with low NOx control to their existing facility. Emissions from this project include 1.64 tons per year nitrogen oxides, 4.85 tons per year carbon monoxide, 0.22 tons per year sulfur dioxide, 1.26 tons per year volatile organic compounds, and 0.26 tons per year particulate matter. Ecology plans to approve the application. We will hold a public comment period on a draft approval order ("air permit") only if a written request is received by Oct. 26, 2021.

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.
