March 16, 2023 - March 31, 2023, 11:59 p.m.

We propose to approve GCX's air quality general order application for their portable rock crushing plant #1, if we find that it meets the conditions of the general order. We will hold a public comment period if one is requested.

GCX has applied for coverage under the general order to operate their portable rock crushing plant #1.

If we determine 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 approval order ("air permit") that includes this change if we receive a written request by March 31, 2023.

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

An air quality general order is a group permit that simplifies the air permitting process. When several sources of air pollution are similar, we can issue a “general order” for all the sources, rather than a series of individual permits.
