1 Loudoun County, Virginia Board of Supervisors Public Hearing March 8, 2010 Powering a Better Tomorrow GEP/S Hybrid Energy Park ZMAP , SPEX & CMPT

2 Local Economic Stimulus During Construction: $183 million per year in revenues during 3 years of construction. 1,205 jobs during construction. One of the largest infrastructure projects in the Commonwealth of Virginia. Annual Local Government Revenue: Estimated $8 to $12 million in County real estate and personal property taxes per year. Estimated $1 million annual to Town of Leesburg Sewer and Water Fund from purchasing of treated effluent. ~Churma Economics & Analytics,“The Economic and Fiscal Benefit of a Proposed Energy Generating Plant in Loudoun County, VA.” November 12, 2009

Benefits Transition off of coal. Electrical generation near demand. Puts Loudoun in forefront of renewable energy by constructing Virginia’s largest solar array. Unique economic development opportunities. Significant annual tax revenue to Loudoun County. Educational opportunities. Energy reliability for the local community. Reduces energy importation. 3

A Unique Location Industrial Area 4 Luck Stone Quarry Overlay Loudoun Water Treatment Plant (future) Leesburg Airport Noise overlay Electrical transmission lines Gas Transmission Lines

5 Existing Resources Two underground natural gas lines on site. Lines from the Gulf Coast, Ohio Valley and liquid natural gas port. Redundancy allows a unique facility that will not need to burn oil or diesel. Natural Gas Transmission Two 230 KV and One 500KV Electrical transmission Lines. North/South and East/West Transmission Distribution. Between two major substations serving Loudoun County. Electrical Transmission Lines

What Are We Proposing? 6 Combined Cycle (Natural Gas and Steam) generator. Natural Gas peak energy generation. Virginia’s Largest Solar array. Wastewater effluent re-use. Best Available Control Technology facility. Low Stack Design. State-of-the-art technology.

Impacts on Energy Supply “In all of the system models that were studied the Green Energy Partners … proposed …generator resulted in a large reduction (between 18% and 21%) in reliance on external power to be delivered through the transmission system to serve the load in the Loudoun County and Leesburg area.” 7 ~ PowerGEM, “Leesburg Generation Study “ (7/7/09)

Energy Policy Revised General Plan – Energy and Communication Policies: “Electric generation facilities that use clean burning and environmentally sound and proven fuel sources for power generation can be located only where their impact on the surrounding land uses and the environment is compatible.” (Page 2-24). 8

9 Off-Setting Environmental Impacts Air Quality - Best Available Control Technology. Water Quality - Chesapeake Bay Cleanup. BMP/LID Only 19% of the site is impervious. Wetlands - No onsite impacts. Very Steep Slopes - No onsite impacts. Noise - Sound Attenuation condition of approval. Visual - Low profile, topographically concealed. Forest Resources - Replacing low quality area with high quality reforestation.

Off-Setting Environmental Impacts Continued Access Road relocation to avoid wetlands, environmentally sensitive resources and wood turtle habitat. Low stack design. Plume abatement. Zero discharge. Effluent re-use to remove harmful nitrates and phosphates from the Potomac River. No diesel fuel. 10

Air Quality “This plant will be designed with the most advanced air pollution control technology to reduce air discharges as any plant in the [United States], western Europe or Japan. This control system is deemed to be the best technology available by the US EPA and the South Coast Air Quality management District in Los Angeles, CA (considered by many to be the premier regulatory agency for controlling smog in the US).” ~ MACTEC,“Revised Air Quality Study of Green Energy Partners/Stonewall Solar and Natural Gas-Fired Power Plant at Leesburg VA,” November 20,

Cleaning up the Bay Re-using up to 3-5 million gallons per day of Leesburg’s waste water. Using treated effluent removes nitrates and phosphates from the Potomac River and the Chesapeake Bay. Zero discharge of water reuse from the energy plant into streams. 12

What Will You See? 14

Plume Abatement Visible plume is caused by ambient conditions of low temperature and high humidity. Plume abatement reduces the visible plume by adding hot dry air to the saturated air leaving the cooling tower. Plume abatement included in Conditions of Approval. 15

Water Reuse Regulated by DEQ pursuant to State of Virginia Code regulation: 9VAC Chesapeake Bay regulated by the U.S. Environmental Protection Agency. Town of Leesburg is permitted by DEQ to withdraw up to 12 million gallons of water per day with no requirement to discharge. Leesburg is currently using between 5 and 6 million gallons per day. The average flow of the Potomac is 18 billion gallons per day. Town of Leesburg has previously negotiated to sell the reuse of its treated effluent. A 2003 Chesapeake Bay Foundation study found that “wastewater discharged from sewage treatment plants is the second largest source of nitrogen pollution in the Chesapeake Bay.” 16

Planning Commission Approval After two public hearings and two worksessions, the Planning Commission on March 3 rd, 2010, recommended approval by an 8-1 vote. Commissioners noted in their findings the environmental benefits of using the treated effluent, which will remove nitrates and phosphates from the Chesapeake Bay. Paying our share: We went beyond mitigating our impacts by proffering cash for a historical narrative, off-site stream monitoring and off-site county trail enhancements. 17 We will plant meadowland habitats conducive to flora and fauna in the solar array area. Commissioners called the project a “win, win, win” and a “great project for the County.”
