This is a 30-day public comment period for the review of VoltaGrid's - Electric Generation Plant draft air permit, technical support document, and notice of construction (NOC) application with associated documents.
We propose to approve VoltaGrid - Electric Generation Plant (VoltaGrid) air quality notice of construction (NOC) application
VoltaGrid submitted a NOC application for their site location east of Road O NW and north of Road L NW, in Quincy. Parcel 0401414050 at Section 4, Township 20 N, Range 24 E. VoltaGrid supplies ready to use affordable, and clean power and fuel solutions for remote and grid-parallel applications.
VoltaGrid is proposing to install 14 prime power natural gas generators, 30 megawatts (MWe) total power supply. VoltaGrid plans to install on the generators, selective catalytic reduction controls for nitrogen oxides and an oxidation catalyst controls for carbon monoxide (CO) and volatile organic compounds (VOCs). Emission increases from this project include:
41 tons per year carbon monoxide (CO)
10 tons per year volatile organic compounds (VOCs)
8.8 tons per year particulate matter (PM)
8.7 tons per year nitrogen oxides (NOx)
6.3 tons per year formaldehyde (CH₂O)
6.2 tons per year sulfur dioxide (SO₂)
We determined this proposal satisfies the requirements of Chapter 173-400 WAC. We plan to approve the application.
Tentative online public hearing: Monday, August 10, 2026, 6 p.m.
(if requested by July 22, 2026, 11:59 p.m.)
