Darigold-Greenfield, Pasco

Air Quality Notice of Construction Application

Jan. 10, 2023 - Feb. 9, 2023, 11:59 p.m.

Ecology proposes to approve Darigold's Greenfield air quality notice of construction (NOC) application.

Para asistencia en español: preguntas@ecy.wa.gov

Darigold is a new facility located at 8201 North Railroad Avenue in Pasco, west of Highway 395 and north of the airport. The proposed project is a greenfield dairy-products facility. The facility's air emissions will come from:

  • Drying milk to produce powdered milk.
  • Natural gas combustion for the boilers and dryer burners.
  • Dryer process, which uses aqueous solutions of acid/base cleaning chemicals.
  • Natural gas emergency generator.

We determined this proposal satisfies the requirements of Chapter 173-400 WAC. We will hold an online public meeting if there is significant public interest.

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.
