We conducted an extensive literature search and compiled an indexed, annotated bibliography on the toxicity of intake chlorinated waters and their disinfection byproducts associated with proposed offshore, open-loop (flow-through), Liquefied Natural Gasification (LNG) terminals and the potential environmental consequences that will result when these substances are discharged into the marine environment. Consideration of the application and licensing of these offshore LNG facilities with open- loop, intake water circulation systems is on-going. Environmental concerns still remain within the regulatory oversight agencies, the commercial and recreational fishing industries, and with the public-at-large. These concerns have specifically focused on the anticipated accumulative high mortalities of commercially- and recreationally-important ichthyoplankton and zooplankton (i.e., decapods or crabs and shrimp). These mortalities will result from the impingement, entrainment, toxic exposure to chlorination and disinfection byproducts (DBPs) associated with treatment of intake waters, and from cold shock during the operation of these proposed LNG open-loop systems. 1 BACKGROUND AND MOTIVATION On November 25, 2002, Congress amended the Deepwater Port Act of 1974 (DWPA) by passing Section 106 of the Maritime Transportation Security Act. Section 106 made the following licensing and regulatory responsibility changes: 1) It redefined, under the DWPA, the Secretary of Transportation’s authorization to issue licenses to own, construct, and operate deepwater ports (i.e., floating or man-made structure other than vessels in federal waters) for the purposes of storing, transporting, or handling oil, to also include natural gas; and 2) It transferred oversight of offshore natural gas terminals from the Federal Energy Regulatory Commission to the Maritime Administration (MARAD) with the Department of Transportation (DOT) and the U.S. Coast Guard (USCG now in the Department of Homeland Security having moved from DOT). To date, the USCG has received 14 applications for Deepwater Port Licenses for proposed Liquefied Natural Gas (LNG) Terminals in the northern Gulf of Mexico. As presently proposed, all but two of these offshore, “platform”/port facilities will need very large volumes of subsurface seawater (probably taken from a staggered array of intake ports located between 10-30m depth) to warm and re-gasify the LNG. These ambient waters which will be chlorinated and subsequently chilled will then have to be discharged back into the marine environment, probably through a turbulent diffuser system. Since these proposed LNG facilities will utilize such an “open-loop” warming system, the various regulatory agencies involved have expressed concerns about possible effects associated with this technology. Namely, that the accumulated impacts of impingement on intake screens and entrainment within the chlorinated and chilled processed waters within these systems may result in significant adverse effects on the early life history stages of fish and decapods and their subsequent adult populations especially for managed species along the AL-MS-LA-TX continental shelf. On February 16, 2005, MARAD’s most recent open-loop decision was handed down granting Shell U.S. Gas and Power’s license to operate the Gulf Landing LNG terminal in West Cameron Block 213, 38 statute miles off Cameron, LA. The terminal will be capable of processing 1 billion cubic feet of gas per day, necessitating that more than 136 million gallons of sea water per day be pumped through its radiator-like system. Two other licenses have been granted: ChevronTexaco (Port Pelican, 36 miles off southwest LA-Vermilion Block 140, first to receive a license on March 31, 2004, for a 176 million gal/day facility); and Excelerate Energy (Gulf Gateway Energy Bridge Deepwater Port, a submersible buoy 116 miles off Cameron, LA, in 91 meters of water, which requires a ship that can regasify the LNG onboard under a license to operate at a peak volume of 76 million gal/day of seawater for 248 days/year) which is now operational (March 20, 2005) and has already offloaded three shipments of LNG. There are presently two (2) other LNG open-loop terminals proposed for the north-central Gulf, i.e., Conoco-Phillips (Beacon Port Clean Energy Terminal, High Island Block 71, 56 miles off the LA-TX border – presently under review); and Torp Technology’s Bienville LNG Offshore Energy Terminal, BOET (Main Pass Block 258, 63 miles south of Mobile Point, AL). Freeport McMoRan Main Pass Energy Hub (Main Pass Block 299, 37 miles east of Venice, LA) recently received (January 3, 2007) approval of its application, which it had amended proposing a closed rack system that will use very little ambient seawater. 3 Finally, both ExxonMobil
