WREG prepared the Air Pollutant Emission Notice (APEN) and fugitive dust land development permit application for the Golden Prairie Wind Farm located in southeastern Colorado. Based on project data supplied, WREG calculated emissions, determined that a permit was necessary, prepared the APEN and permit forms for signature, and compiled and submitted the required supporting materials to the state. WREG worked with the state permit engineer to ensure that the permit was issued prior to the construction start date, thereby avoiding construction schedule impacts.
WREG assisted Toltec Power Station, LLC with permitting for a planned 2,000 megawatt natural gas-fired combustion turbine project near Eloy, Arizona. WREG prepared a combined construction/operating permit application for submission to Pinal County. WREG identified all applicable requirements, prepared Best Available Control Technology (BACT) analyses, and analyzed air quality impacts. The air quality impact assessment included estimation of Class I and Class II visibility impacts using PLUVUE and CALPUFF, cumulative National Ambient Air Quality Standards (NAAQS) and Class II increment analyses, and Class I increment consumption modeling.
WREG also supported the applicant in hearings for a Certificate of Environmental Compatibility (CEC) from the State Siting Committee of the Arizona Corporation Commission. As part of the hearing process, WREG conducted cooling tower visible plume modeling using the SACTI model. WREG also prepared Acid Rain Provision documentation.
WREG prepared the Prevention of Significant Deterioration (PSD) and operating permit application for the Panda Gila River Project in Maricopa County, Arizona. The project was developed by Panda Gila River, LP. The project is a combined-cycle combustion turbine facility capable of generating 2,080 megawatts of electrical power. WREG prepared an initial permit application including emission estimates, applicable requirements identification, Best Available Control Technology (BACT) analyses, and an air quality impact analysis. During the permit review and negotiation process, WREG conducted analyses on fugitive particulate matter emission reductions associated with the project, and prepared an ambient particulate matter monitoring plan/Quality Assurance Project Plan (QAPP). WREG also prepared documentation required under the Acid Rain Provisions of the Clean Air Act for submission.
WREG researched the status of integrated gasification combined cycle (IGCC) technology for a client in the Rocky Mountain region. We evaluated gasification technologies, gas composition, emissions, emission controls and control opportunities (mercury and carbon dioxide [CO2]), air permits issued to IGCC projects, other environmental considerations, capital costs, operating and maintenance costs, status of US Department of Energy (DOE) research, and availability of DOE funding. The client will use the information developed in evaluating future resource options. WREG also prepared feasibility studies, including emission calculation, extensive dispersion modeling, and Best Available Control Technology (BACT) research, for an IGCC plant considered for a site in southeastern Arizona.
Bowie Power Station, LLC, retained WREG to prepare a combined construction/operating air permit application for a 1,000-megawatt natural gas-fired combustion turbine project to be located in southeast Arizona.
The permit application included a description of applicable requirements and compliance methods, Best Available Control Technology (BACT) analyses, and a detailed air quality impact analysis. CALPUFF, VISCREEN, and PLUVUE were used to estimate visibility impacts in nearby Class II areas, as well as visibility effects in four Class I areas.
Acid rain provision documentation was also prepared. The project was recently repermitted as a 500-megawatt facility with updated BACT and dispersion modeling analyses.
