Greenidge plant in New York getting new permits – that don’t include coal as a fuel

The New York State Department of Environmental Conservation will be out for public comment until July 29 on a draft Title V Facility Permit and Title IV (Acid Rain) Facility Permit for the Greenidge Generating Station in the Town of Torrey, with those revised permits excising coal as an allowed fuel at the plant.

The Title IV permit and the Title V permit replace the Title IV and Title V permits relinquished by the previous owner in November 2012. The current plant operator is Greenidge Generation LLC. Greenidge Unit 4 is a 106.3-MW steam turbine facility.

“Coal is no longer authorized for use at the facility,” said a draft permit. “Except for discontinuing the use of coal as the primary fuel, authorized operations are unchanged from those authorized prior to November 2012, and include boiler powered electric generation and ash handling operations.

“Unit 4 electric generating operations will be operated without the use of coal. Electric generation is powered by a boiler with a maximum heat input of 1,117 million BTU per hour. The boiler will burn untreated wood, waste wood product from a furniture manufacturer, #2 fuel oil, diesel oil, waste oil, and/or natural gas. A subsequent conversion of all generating operations to use natural gas as the primary fuel is also planned during the term of this permit.”

A multi-pollutant control system for the boiler was installed in 2006. Boiler NOX emissions are controlled by over fire air, natural gas reburn, selective non-catalytic reduction, and selective catalytic reduction. Boiler SO2 emissions are controlled by a spray dry reactor. Boiler particulate emissions are controlled by a baghouse. The equipment to allow firing with wood was added in 2009.

A company contact listed in the permit documents is: Dale Irwin, Greenidge Generation LLC, 590 Plant Rd, PO Box 187, Dresden, NY 14441-0187, Phone: 315-536-3423.

Last September, Greenidge Generation applied with the New York State Public Service Commission for approval of the Unit 4 restart and fuel conversion. Said Irwin, as President and Secretary of the company, in a brief June 21 update filed with the PSC in this still-pending case: “I have read the foregoing Verified Petition of Greenidge Generation LLC for an Expedited Order Granting an Original Certificate of Public Convenience and Necessity and Lightened Regulation (the “Petition”) filed in this proceeding on September 10, 2015, and state that I know the contents thereof and that the facts stated therein are true to the best of my knowledge, information and belief. I further state that Greenidge Generation LLC has obtained all of the municipal approvals required for the operation of Greenidge Unit #4 as detailed in the Petition.”
