LIQUEFIED NATIONAL GAS (LNG) PROJECTS UPDATE
Southwest Region, September 20, 2006
Print Friendly Version
The Federal Energy Regulatory Commission (FERC) has issued a DEIS for the Calhoun LNG Project in Lavaca Bay, near Point Comfort, Calhoun County, Texas.  The project consists of construction of (1) a marine terminal including a ship maneuvering area, (2) two storage tanks for LNG, (3) a LNG vaporization and processing system, (4) various support buildings, (5) 27.1 miles of 36 inch natural gas pipeline, (6) 0.25 mile of 8 inch diameter lateral leading to Formosa Hydrocarbons Company, and 0.25 mile of 16 inch diameter lateral leading to Transco meter station, (7) ten delivery points, and (8) a pig launcher and receiver facility with one mainline valve.  In addition, two facilities not under the jurisdiction of FERC would be constructed: a natural gas liquid recovery system and an American Electric Power (AEP) transmission line.  The purpose of the project is to provide facilities necessary to import, store and vaporize LNG and deliver natural gas via interstate and intrastate pipelines as well as to supply natural gas to local industrial customers such as Formosa Hydrocarbons Company and Formosa Plastics Corporation. The proposed pipeline route would be constructed and operated in Calhoun and Jackson Counties, Texas.  Construction of the LNG terminal would require approximately 73 acres of land and the dredging of 79.3 acres of Lavaca Bay owned by the Calhoun County Navigation District.  Construction of the proposed pipeline would disturb approximately 416.6 acres including the pipeline route, temporary workspaces, and access roads.  After construction, operation of the entire pipeline project would require approximately 105.8 acres for a permanent easement.  Approximately 4,200,000 cubic yards of sediment would be dredged for creation of the marine terminal area and placed in-bay or upland confined placement areas.  The proposed pipeline construction would temporarily impact approximately 19.49 acres of scrub-shrub and herbaceous wetlands, permanently impact approximately 2.63 acres of forested wetlands.  As mitigation, for the impacts to forested wetlands, Calhoun LNG is proposing to preserve an in-kind area in a nearby watershed or purchase out-of-kind mitigation back credits.  To minimize impacts of dredge material placement in the open bay, Calhoun LNG is proposing to use the majority of their dredge material to cap existing mercury contaminated sites in order to enhance the recovery of Lavaca Bay.  An interagency team including the Service, National Marine Fisheries Service, Environmental Protection Agency, Texas Parks and Wildlife, and Texas Commission on Environmental Quality have been meeting to discuss issues related to dredge material placement and appropriate mitigation.
