Tapani Rockwool Plant, portable rock crusher
Air quality application for general order coverage – Opportunity to request a public comment period
Aug. 11, 2025, 12 a.m. - Aug. 26, 2025, 11:59 p.m. PT
We propose to approve Tapani Rockwool Plant's air quality general order application for a portable rock crusher. We will hold a public comment period if one is requested.
Tapani applied for coverage under the general order to operate its Rockwool Plant portable rock crusher. Tapani agreed to meet the requirements of the general order for a portable rock crusher.
Document 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 August 26, 2025.
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.

Background
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.
