Wildcat Point is a natural gas 2x1 combined-cycle power plant with a Mitsubishi M501 GAC gas turbine with dry low nitrogen oxide (NOx) combustors. The plant will be adjacent to the Old Dominion Electric Cooperative (ODEC) Rock Springs plant. Burns & McDonnell was retained to provide siting assistance, development assistance, permitting assistance and preliminary engineering services for the 1,000-MW combined-cycle generating facility.
The Burns & McDonnell scope includes these development activities:
- Site infrastructure evaluation and engineering support
- Permitting assistance including engineering support for permitting
- Conceptual design and scope definition including development of performance estimates, capital cost estimates, operating & maintenance cost estimates, and a conceptual schedule
- Evaluation of F, G, and H class gas turbine technologies
- Evaluation of various plant configuration options
- Owner's engineer
- Project development
- Permitting support
- Certificate of Public Convenience and Necessity (CPCN) assistance
- CPCN expert testimony support
- Wetlands permitting
- Cultural resources approval
- Threatened and endangered species studies
- Noise monitoring and modeling study
- NPDES stormwater construction
- Public meeting assistance
- Preliminary engineering
- Specification preparation
- Negotiations support
- Document review
- Construction oversight
- Startup and commissioning oversight
Burns & McDonnell's efforts include gathering all the required pre-construction environmental permits, clearances and authorizations and additional general assistance. The preconstruction permits and studies included: Prevention of Significant Deterioration (PSD) and Title IV Acid Rain; noise monitoring and the generation of a noise study; a construction and post-construction traffic impacts study; state and federal threatened and endangered species approval; wetland delineation efforts and submittal of the applicable wetland permit application; cultural resource approval; and Federal Aviation Administration notifications. In addition, the firm is assisting ODEC with the preparation of documents and studies that support the necessary Certificate of Public Convenience and Necessity (CPCN) application process, a required certificate for the construction and operation of the plant. Burns & McDonnell provided expert testimony and review of the client's expert testimony to support the application effort. Burns & McDonnell also is providing public outreach support for the public meetings and generation of renderings to help define the proposed power plant and intake infrastructure.
The project is in a nonattainment area for ozone, so the air permit application included both nonattainment new source review (NNSR) for ozone and PSD review for particulate matter (PM10, PM2.5), carbon monoxide (CO), volatile organic compounds (VOC), sulfur dioxide (SO2), sulfuric acid (H2SO4), carbon dioxide (CO2), greenhouse gases, and NOx emissions. A Lowest Achievable Emission Rate (LAER) and a Best Available Control Technology (BACT) analysis were performed, including BACT for greenhouse gas emissions. Air dispersion modeling included modeling for the stringent one-hour NOx and SO2 standards as well as the new stringent PM2.5 24-hour and annual standards. Burns & McDonnell also assisted with an analysis on the use of offsets from neighboring nonattainment areas.
Burns & McDonnell is also providing permitting assistance for obtaining permits and approvals for a 5-mile water supply/discharge pipeline that is being constructed. The pipeline will connect the plant with the Susquehanna River. The pipeline permits and approvals that Burns & McDonnell is completing include: a joint permit application for the Section 404 and 401 permit (for wetlands); threatened and endangered species habitat assessments for necessary clearances (federal and state); performing cultural resources studies that were submitted for the necessary clearances; zoning clearance documentations; traffic study impacts; and right-of-way acquisition support efforts.
