Elma, WA

What projects are proposed?

Energy Facility Site Evaluation Council (EFSEC) Draft Prevention of Significant Deterioration (PSD) and Notice of Construction (NOC)

EFSEC is proposing to issue a Prevention of Significant Deterioration (PSD) and Notice of Construction Permit No. EFSEC/2001-01, Amendment 5 to Grays Harbor Energy Center, LLC (GHEC), which is a minor modification of the current Permit. The GHEC is located at 401 Keys Rd, Elma, WA 98541.

GHEC is planning to install General Electric (GE) combustion turbine (CT) upgrades, which include the Advanced Gas Path (AGP) upgrade. This is an upgrade package for components of the CT that will allow for more efficient combustion of natural gas within the turbines and increased turbine capacity. The installation of the AGP upgrade, the nominal plant capacity will increase from 650 MW to 662.4 MW at 100% load and 59 degrees F.

GHEC is requesting the permit limits in amendment 4 are unchanged with the following:

  • No new impact analyst
  • No new Best Available Control Technology (BACT) determinations

The proposed revisions will revise the following existing permit requirements:

  • New formaldehyde emission limit and monitoring (air toxics regulations)
  • Add monitoring of inlet temperature for the carbon monoxide catalyst
  • Add emissions reporting for Washington Administrative Code (WAC) 173-400-720(4)(b)(iii)(D)(iii)
  • Clarify the amount of sample for the Particulate Matter (PM) testing
  • Clarify that emissions testing shall be performed in the winter months – highest expect emissions rate

The EFSEC preliminary determination finds that the project:

  • Satisfies the requirements for using BACT for regulated air pollutants (prior determinations).
  • Will not cause or contribute to a violation of any ambient air quality standard (prior determinations).
  • Will comply with all applicable local, state, and federal regulations established pursuant to Federal and Washington State Clean Air Acts.

WAC 173-400-740(3)(e) requires that this public notice list how much increment (or the amount of pollution an area is allowed to increase) will be consumed by the project. For this project, there is no increment consumed because criteria emissions are not increasing due to this amendment.

EFSEC is proposing to amend No. EFSEC/2001-01, AMENDMENT 4.
