  1. Freeport Generating ProjectProject Description • Modernization projects at Power Plant #2 • Developers – Freeport Electric and Selected Development Company • Adjoining Facilities – (2) General Electric LM-6000s, simple cycle design represents state of the art efficient and clean power generation technology • Output • Freeport Electric 45-50 MW • Development Company 45-50 MW • Fuel – Natural Gas with a back up of Low Sulfur distillate oil • Decommission diesel units 1&2 • Retention of existing combustion turbine for backup, emergency use only

  2. Freeport Generating ProjectVillage Project Purpose • Meet Freeport Electric’s Installed Capacity Requirements for Long Island-based generation set by NY Independent System Operator (NYISO) • Replace older diesel generation at PP#2 • Reduce Emissions • Moderate energy costs during peak load periods • Eliminate deficiency payments for Capacity • Improve Operating Capability • Provide capacity for future load and economic growth

  3. Freeport Generating ProjectDeveloper Project Purpose • Supply power utilizing environmentally competitive technology • Produce power at market competitive prices • Develop project with high level of reliability and operating flexibility to meet regional Long Island demand • Create generation resource base to support market objectives

  4. Freeport Generating ProjectKey Environmental Permits and Approvals • New York State Environmental Quality Review (SEQR) • New York State Department of Environmental Conservation Air Permit • Natural Gas Pipeline Route (New York State Public Service Commission – Article VII Review)

  5. Freeport Generating ProjectOther Environmental Areas of Concern • Threatened and Endangered Species • Wetlands • Stormwater and Seasonal Storms • New York State Office of Parks, Recreation, and Historic Preservation

  8. Freeport Generating ProjectAir Quality Improvements • Retirement of two existing, older, Fiat diesel generators • Installation of two efficient and clean firing GE LM6000 combustion turbines • Use of clean burning fuels to minimize emissions of sulfur dioxide (SO2) and particulate (PM10) • Natural gas as primary fuel • Low sulfur (0.05%) distillate oil as backup fuel if gas supply is interrupted • Use of state-of-the art emissions control systems • Selective Catalyst Reduction (SCR) to control nitrogen oxides (NOx) • Oxidation catalyst to control carbon monoxide (CO)

  9. Freeport Generating ProjectAir Quality Improvements • Use of higher stacks (170 feet above local ground level) near Good Engineering Practice stack height defined by U.S. Environmental Protection Agency (EPA) will minimize local impacts of emissions • Maximum predicted impacts of proposed LM6000 combustion turbines considered insignificant under EPA criteria • Potential to improve existing air quality on Long island through the displacement of power generation from existing, older technology and less efficient power plants

  10. Freeport Generating ProjectEmissions Controls • New combustion turbines at Power Plant #2 will use state-of-the-art emissions control technology, good combustion practices, and clean burning fuel • New combustion turbines will achieve significantly lower emission rates relative to existing, older technology power plants • Advanced technologies (Selective Catalytic Reduction and water injection) will be used to control nitrogen oxide (NOx) emissions • SCR control technology injects aqueous ammonia (solution of 81% water and 19% ammonia) to control NOx emissions • Aqueous ammonia has been transported to and used safely for more than a decade for a wide variety of purposes (e.g., agricultural uses, power plants) • An oxidation catalyst will be used to control emissions of carbon monoxide (CO) • Clean fuels (natural gas with very low sulfur distillate oil backup) will minimize emissions of sulfur dioxide (SO2) and fine particulate matter (PM10) • Continuous emissions monitors (CEMS) will be used to continuously monitor emissions of NOx

  11. Freeport Generating ProjectNoise • NYSDEC noise guidance document recommends increase in noise be limited to no more than 6 dba over existing levels • Village ordinance limits commercial industrial sources at neighboring residential-zoned uses, locations where people congregate, and other industrial zoned uses

  12. Freeport Generating ProjectProject Infrastructure Requirements • Water Supply: 160,000 gallons / day (Peak Use) • Process Wastewater Discharge: 750 gallons / day • Solid Wastes (Non-Hazardous): No net change Above existing conditions • Traffic • Construction Phase • Impacts from Construction Traffic will be short term effects. Construction is scheduled for a maximum of 5-6 months. • During the peak construction period there will be a maximum of 150 workers per shift. • Operation Phase • No net change above existing conditions
