Lon C. Hill LP is continuing to advance its permitting for an up to 740-MW, gas-fired, combined-cycle power plant project in Neuces County, Texas, at a former power plant site.
In November 2013, it filed an application with the U.S. Environmental Protection Agency Region 6 office for a prevention of significant deterioration (PSD) greenhouse gas (GHG) permit for the project. On June 18, it filed with the EPA a cultural resources report.
Under that report, Lon C. Hill is seeking concurrence from the Texas Historical Commission (THC)/State Historic Preservation Officer and the EPA that the construction and operation of the power station will not affect historic properties listed in the National Register of Historic Places or that meet the criteria for the NRHP in accordance with Section 106 guidance. The proposed project is subject to PSD review for greenhouse gases by the EPA, so it is subject to regulation under Section 106 of the National Historic Preservation Act.
Lon C. Hill proposes to construct a 2x2x1 combined cycle power plant. It will consist of two natural gas-fired combustion turbines, two heat recovery steam generators, and one steam turbine. The combined cycle unit will exclusively fire natural gas. The facility’s nominal capacity will be between 625 MW-740 MW.
The project will use existing permitted wastewater and storm water outfall structures. One existing pipeline will be upgraded by a third party (the gas transportation provider) to a larger diameter pipe. The proposed project will use existing power lines.
The proposed project area is located near the Calallen District in the City of Corpus Christi, Nueces County. It is about 0.75 miles south of Interstate 37 and about a mile east of US Highway 77. The area previously hosted a power station with four cooling towers that was shut in 2002 and then demolished down to the foundations.
