Air Quality Notice of Construction – Opportunity to request a public comment period

April 8, 2021 - April 23, 2021, 11:59 p.m.

This is a public notice of a revision to an air quality permit. Ecology will hold a public comment period if one is requested.

Helena Agri-Enterprises (HAE) submitted an air quality Notice of Construction application for their facility at 82 Central Ferry Road in Pomeroy. HAE plans update their air permit, Approval Order No. 19AQ-E018, by adding two new cooling towers, two new propane-fired boilers, and 10 more storage tanks for fertilizer. They also requested the ability to work with different contractors to manufacture ammonium polyphosphate fertilizer. The new equipment and the option of operating a mobile pipe reactor for the fertilizer will be a marginal increase in criteria pollutants. Ecology plans to approve the application. We will hold a public comment period on a draft approval order ("air permit") that includes this change only if a written request is received by April 23, 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.
