Lamb Weston, Pasco

Air quality notice of construction application

Aug. 24, 2026, 12 a.m. - Sept. 30, 2026, 11:59 p.m. PT

We propose to approve Lamb Weston's Pasco air quality notice of construction (NOC) application.

Lamb Weston submitted a notice of construction application for their Pasco plant located at 960 Glade Road. They propose to install advanced wastewater treatment facilities, including a boiler, flare, and emergency engine. The facility will have odor and sulfur controls.

Emission increases from this project include:

  • 11.31 tons per year carbon monoxide (CO)
  • 7.17 tons per year volatile organic compounds (VOCs)
  • 4.46 tons per year sulfur dioxide (SO2)
  • 4.31 tons per year of nitrogen oxides (NOx)
  • 0.62 tons per year particulate matter (PM10 and PM2.5)

Documents for review

We determined this proposal satisfies the requirements of Chapter 173-400 WAC. We plan to approve the application.

Tentative public hearing

Monday, Sept. 28, 2026, 6 p.m. online
(if requested by Sept. 16, 2026, 11:59 p.m.)

We will hold a public hearing if there is significant public interest. A request for an online public hearing must include the interest of the person making the request and why a public hearing is needed. If you request a public hearing, please tell us if you need interpretation in a language other than English. If we do not receive significant written requests for a public hearing by Sept. 16, 2026, then the online public hearing will be cancelled.

Background

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.
