DEC Application

Article 19 Title V Air Permit (ID No. 8-5736-00004/00017)

Project Description

Greenidge Generation LLC (Greenidge) filed an application to renew its Clean Air Act Title V air permit 8-5736-00004/00017, effective September 7, 2016, for the continued operation of a natural gas-fired electric generating facility (facility) in the Town of Torrey, Yates County, on Seneca Lake.

The facility is a primarily natural gas-fired electric generating plant, with a generating capacity of approximately 107 megawatts (MW) with a maximum heat input which is limited to 1,117 million BTUs per hour.

The renewal application requests renewal of the existing permit, with revisions limited to: removal of the diesel fire pump permit conditions because the diesel fire pump has been taken out of service and removed from the facility, and minor revisions to the monitoring requirements for particulate emissions (PM-10, PM-2.5 and Particulates), which includes the use of a flowmeter for the facility to demonstrate continuous compliance with the existing PM-10, PM 2.5 and Particulates permit conditions.

The New York State Department of Environmental Conservation (DEC) Division of Environmental Permits denied the renewal request on June 30, 2022, pursuant to title 6 of the Official Compilation of Codes, Rules, and Regulations of the State of New York (6 NYCRR) 621.10(f). The denial was based on the determination that the facility's continued operation would be inconsistent with or would interfere with the attainment of the Statewide greenhouse gas (GHG) emission limits established in article 75 of the Environmental Conservation Law (Climate Leadership and Community Protection Act [CLCPA]) and reflected in 6 NYCRR part 496. On July 28, 2022, Greenidge Generation, LLC filed a hearing request on the denial.

A pre-adjudicatory issues conference was convened on December 8, 2022, and is adjourned until January 4, 2023 at 9:00 am. The issues conference will be held virtually using the Webex audiovisual conference platform. Participation in the issues conference is limited to the parties and petitioners for party status. Members of the public may attend the issues conference via the internet or listen via telephone.

SEQRA Status
