Permit(s) Applied for (Application Number)

Article 19 Air Title V Facility (8-5736-00004/00017)
Article 19 Title IV (Phase II Acid Rain) (8-5736-00004/00016)

Project Description

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 Facility is located in the Town of Dresden, Yates County

Greenidge Station submitted a timely Title V renewal application requesting a 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 a request for 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, PM2.5 and Particulates permit conditions.

Review Process Summary and Status

Greenidge's Air Title V and Title IV (Acid Rain) permits were issued on September 7, 2016, and expired on September 6, 2021. These permits were extended (in accordance with the State Administrative Procedures Act) on September 6, 2021. Because the renewals were submitted to DEC on a timely basis, by operation of law, the facility may operate under the terms of its existing permit while DEC considers the renewal application.

On September 1, DEC determined that draft renewal Title IV (Acid Rain) and Title V air permits for Greenidge Generation were ready to be issued for public review and comment. DEC released the draft permits for public comment on September 8, and held virtual public comment hearings at 1 p.m. and 6 p.m. on Oct. 13, 2021.

DEC has not made a determination regarding the final issuance of permits to Greenidge Generation. While sufficient information has been submitted to begin the required public review, at this time the applicant has not demonstrated compliance with the requirements of the Climate Leadership and Community Protection Act, including requirements regarding greenhouse gas emissions.

This is the first step in DEC's public process for this project and the public was encouraged to submit comments on the draft permits by November 19, 2021. Before making a final decision on the draft permits, DEC will thoroughly review all comments received and any additional information submitted by the applicant. Since Greenidge Generation applied to renew these required air permits, DEC has conducted a rigorous review of application materials and requested additional information.

Prior to issuing any permit for a proposed project, DEC needs to ensure compliance with the requirements of New York's ambitious Climate Leadership and Community Protection Act (CLCPA). There are substantial greenhouse gas (GHG) emissions associated with the project. Based on information currently available, the applicant has not demonstrated that the project is consistent with the attainment of statewide GHG emission limits established in the Climate Act, nor has the applicant provided a detailed justification notwithstanding this inconsistency or proposed sufficient alternatives or GHG mitigation measures. As part of the public review, DEC specifically sought public comments on the project's compliance with the Climate Act, including the potential need or justification for the project as well as appropriate GHG mitigation measures.

Greenidge has "not shown compliance" because the application does not currently meet the requirements of the CLCPA, notably it has not to date shown that it is consistent or would not interfere with the attainment of statewide greenhouse gas emission limits; nor has it provided sufficient justification or identified alternatives or sufficient mitigation.

The public comment period was extended and ended on November 19, 2021. DEC is currently reviewing the approximately 4,000 public comments to determine next steps, including if a hearing would be held to obtain additional input on the application prior to making a decision. Copies of the public comments can be obtained by submitting a FOIL request. Documents and other information are listed below.
