In the event a sp i l l occurs froa east Cameron 240, FMP Operating has projected trajectory of a spi l l uti l izing Inforaation In the Envlronaental Impact Statement (EIS) f * r OCS Least Salts 118 and 122.

The EIS contains oil s p i l l trajectory simulations using seasonal surface currents coupled with wind data, adjusted every 3 hours for 30 days or until a target Is contacted.

Hypot ietical spill t rajectories were simulated for each of the potential launch sites across the entire Gulf. These simulations presume 500 spi l ls occurring In each of the four seasons o* the year The results In the EIS were presented as probabilities that JM oi l spi l l beginning froa a par t icu lar launch s i te would contact a certain land segaent within 3, 10, or 30 days. Utilizing the summary of the trajectory analysis (for 10 days), the probable projected land fal l of an oi l sp i l l froa best Caaeron 240 Is as fol lows. Also listed Is the CGA Nap Nuaber (corresponding to the land segment) which will be ut i l ized to determine environmentally sensitive areas teat aay be affected by a s p i l l .

I I . DESCRIPTION OF AFFECTED ENVI

A. COMMERCIAL FISHING

Tht Gulf of Mexico provides 40% of the commercial fish landings In the contlntental United States. Louisiana ranked first among Gulf states In total commercial fishery landings for 1987 with nearly 1.8 billion pounds landed, valued at $316 million. i tior.ally, tKe Louisiana catch ranked f i rs t In volume and second In vah- Cameron, Louisiana was the leading U.S. port In quantity of commercial ' r landings.

Louisiana landed 45% of the shrimp, 65% of the oysters, and 80% of the menhaden harvested from the Gulf In 1987. Menhaden represents the highest quantity with 1.6 billion pounds landed and shrimp represents the highest value at $185 million. In addition, each ' the following species ac­counted for landings valued at over $1 million: spotted seatrout, red snapper, vermilion snapper, bluefln tuna, black drum, red drum, blue crab, American oyster, and swordflsh.

Louisiana is the most productive state In the Gulf of Mexico In terms of commercial fisheries because of Its extensl e estuaries, coastal marshes, and nutrient input from the Mississippi and Atchafalaya Rivers. Coastal Louisiana contains approximately 60% of the estuaries and marshes In the Gulf of Mexico. Over 90% of the blue crib harvest, which amounts to about SO million pounds, comes from estuary nursery areas.

B. SJIPPIK The establishment of a series of safety fairways ir traffic -.operation scheme* (TSS's), and anchorage areas provide unobstructed aprroach for vessels using U.S. ports. Shipping safety fairways are lanes o. corridors In which »r fixed structure, whether temporary or permanent. Is permitted. TSS's Inc. • navigation safety by separating opposing lanes of vessel traffic, .t.rwty anchorage art areas contiguous to and associated with a fairway, in which fixed structures may Jx* permitted within certain spacing limitations.

Fairways ol ly an Itrrortant rol* In the avoidance of collisions on the OCS, particularly Ir. the case of tha large oceangoing vessels, but not all vesselr stay within the fairways. Many others, such as fishing boa's and OCS support vessels, travel through areas with high concentration of fixed structure.. In such cases the most Important mitigation factor 1s tht requirement for adequate marking and lighting of structures. After a structure has been In place for a while, It often becomes a landmark and an

aid to navigation for vessels that operate In tht a»*ta on a regular basis.

West Cameron Blocks 240/231 have a shipping fairway crossing from north to south. Tht platfone/rlg and tach of tht marine vessels servicing this operatio.. will bt equipped with all U.S. Coast Guard required navigational safety aids.

C. PLEASURE BOATING. SPORT FISHING ATM RECREATION

The northern Gulf of Mexico coastal zone Is one of the major recreational regions of the United States, particularly In connection with marine fishing and beach-related activities. The coastal beaches, barrier Islands, estuarine bays and sounds, river deltas, and tidal marshes are extensively and Intensively utilized for recreational activity by residents of the Gulf South and tourists from throughout the Nation. Publicly-owned and administered areas such as National seashores, parks, beaches, and wildlife lands, as well as specially designated preservation artas such as historic and natural sites and landmarks, wilderness artas, wildlife sanctuaries, and scenic rivers attract residents and visitors throughout tht ytar. Commercial and private recreational facilities and establish­ments, such as resorts, marinas, amusement parks, and ornamental gardens, also strvt as primary Interest artas and support services for people who seek enjoyment from the recreational resources associated with the Gulf.

The two major recreational areas most directly associated with tht offshort leasing and potentially affected by it art tht offshore marine environment and the coastal shorefront of the adjoining states. Tht only major recreational activity occurring on tht OCS Is offshort marine recreational fishing and divlnj. Major sport species sought and caught offshore Include snappers, groupers, seatrout, croakers, macktrtls, amberjack, cobla. dolphin, tarpon, and blllflshes. Studies, reports, and conference proceed­ings published by MMS and others have documented a substantial recreational fishery Including scuba diving, directly associated with oil and gas production platforms. The recreational fishing associated with oil and gas structures stems from their function as high profile artificial fishing reefs. A report on the 1984 Marine Recreational Fishery Statistics Surveys presented by NMFS at the Sixth Annual Gulf of Mexico Information Transftr Meeting Indicates a majority of the off short recreatioi.al fishing In the Central and western Gulf of Mexico Is directly associated with tht oil and gas structures. Thtrt art currently about 4,000 offshort oil and gas structures In tht Ctntral and Wtsttra Gulf of Mexico. Many other studies have demonstrated that when oil and gas structures are accessible to marine recreational fishermen and scuba divers they art a major attraction for marine recreational activities and a positive Influence on tourism and coastal economics.

WHh the exception of Grand Isle and vicinity and a stretch of beach area In Cameron Parish, (Peveto/Constance/Ocean View Beaches, Holly Beach, Hackbtrry Beach) Louisiana has vtry limited beach arte suitable for recreation. Most of It Is vtry narrow, of poor recreational quality and generally Inaccessible by automobl.t. Some of tht hlghtst quality beach

Exhibit 14 (3/13)

areas In coastal Louisiana art found along tht barrier islands chain off Terrebonne Parish. Several additional significant recreational resources art found along the Gulf Coast. Louisiana has ornamental gardens, scenic roads, r l v t rs , and t r a i l s .

D. POTENTIAL OR KNOWN CULTURAL RESOURCES

An Archaeological Report was required for West Cameron Blocks 240/231. I f FMP discovers any archaeological resource while conducting operations on the lease area, FMP wi l l report the discovery Immediately to the Regional d i rec tor . FMP will make every reasonable effort to preserve the archaeological resource unti l the Regional Director has told FMP how to protect I t .

E. ECOLQfilCAlhY SENSITIVE FEATURES

Barr ie r beaches art a common landform along the Gulf Coast and stretch In an Irregular chain from Florida to Texas. These elongated, narrow land-forms are composed of sand and other loose sediments transported by waves, currents , storm surges, and wind. Barrier landforms are a young coastal feature. The tana "barrier" identifies the structure as one that protects other features, such as bays, estuaries, and marshes, from direct Impacts of the open ocean. By separating coastal waters from the ocean, barriers contribute to the amount of estuarine nabltat along the coast. As much as two-thirds of the top value Atlantic and Gulf Coast species of f 1 sh are considered to be directly dependent during some stage of their l i f e on conditions In these estuaries.

Another benefit of both tht Islands and their adjacent marshes and bays I t that of providing habitats for a large number of birds and othtr animals, Including several threatened or endangered specie:, for example, tht loggerhead turtle, tht southern bald eagle, a l l igators, and brown pti leans.

Louisiana has tht most rapidly retreating beaches In tht nation. Tht averagt retreat for tht Fourchon beach ovtr tht last 100 ytars has been In txcess of 60 ft /yr. The statewide avtragt according to Dolan tt a l . (1982) I s In txctss of 12 f t /y r . Beaches along the deltaic plain In Louisiana f i t Into one of three categories, depending on tht stagt of tht deltaic cycle that the landmass Is experiencing. When a major distributary of the Mississippi River Is abandoned, subsidence results ! i a local sea level transgression that transforms the active delta Into an ero-ionai headland with flanking barriers. Fourchon Beach Is an example of an eroding headland beach. With Increased age and subsidence, the barrier shoreline evolves Into a transgressive barrier Island arc that Is separated from the mainland by a lagoon. I s l e s Dtrnltrs 1s an example cf this phenomenon. Eventually with continued subsidence and sediment deprivation, the Island ceases to exist.

The Import ancs of coastal wetlands to the coastal environment has been well documented. Coastal wetlands are characterized by high organic produc-

4

Exhibit 14

t i v l t y , high detritus productlc.i, tnd efficient nutrient recycling. They provide habitat for a great nuaber and wide diversity of Invertebrates, f i s h , harptllts, birds, and mammals, wetlands are particularly Important as nursery grounds for juvenile fonts of aany Important f 1 sh species. The Louisiana coastal wetlands support over two-thirds of the Mississippi Flyway wintering waterfowl population and the largest fur harvest In North America.

Louisiana contains most of the Gulf coastal wetlands. The deterioration of coastal wetlands, particularly In Louisiana, 1s an Issue of concern. In Louisiana, the annual rate of wetlands loss has been measured at SO square miles for tha period 1955-1978.

A recent study funded by MMS entitled "Causes of wetland Loss In the Coastal Central Gulf of Mexico", examined coastal ecosystems of the Northern Gulf of Ntxlco region and how wetland habitats havt changed as a r e s u l t of natural processes and man's act iv i t ies thereon. Tht study's primary focus was on assessing and quantifying tht direct and Indirect Impacts of OCS-related act iv i t ies on wetland artas. Canal construction for pipel Ints and navigation has been the major OCS-related Impacting factor.

The shelf and shelf edge of the Central and western Gulf are characterized by topographic features which are Inhabited by benthic communities. The habitat created by the topographic features Is important because they support hard-bottom coeaeunltles of high blomass, high diversity, and high numbers of plant and animal species; they support, either as shelter, food, or both, large numbtrs of commercially and recreatlonally Important f ishes; they are unique to the extent that they are small Isolated areas of coeaeunltles In the vast Gulf of Mexico; they provide a relatively pristine area suitable for sc ien t i f i c research; and they have an aesthetically at tract ive intrinsic value.

The Central Gulf of Mexico l i s t s 18 topographic features. None of these topographic feastures are situated near West Cameron Blocks 240/231.

F . PIPELINES AND CABLES

There Is ont Chevron 14" piptl int crossing from west to test In tht arte.

6. OTHER mOmt USES The activities proposed for West Cameron Blocks 240/231 will havt no direct or Indirect impact on other mineral uses.

N. OCEAN DUMPING

Ocean dumping Is prohibited In this area.

Exhibit 14 (7/13)

I. EKOANGERFO AMD THREATENED SPECIES AND CRITICAL HABITAT

Six Federally listed endangered whale species may occur in the Gulf of Mexlco--the blue, f in , numpback, right, Bit , and sperm whales. Generally, these large cetaceans Inhabit the continental slope and deep oceanic waters; ocasslonally. they are sighted nearshore. Right whales are the most endangered cestacean In the Gulf of Mexico.

The FWS has designated IS threatened or endangered species that could be affected by OCS oil and gas operations In the Gulf. All but the American crocodile Inhabit the Central and Western Gulf. The l i s t Includes three mammals (the jaguarundl, ocelot, and West Indian manatee), seven birds (the bald eagle, arctic pergrlne, whooping crane, brown pelican, esklmo curlew, piping plover, and least tern), and six repti les (the American crocodile and the hawskblll, Kemp's ridley loggerhead, leatherback, and green sea t u r t l e s ) .

The green sea turtle 1s threatened in Louisiana. The Kemp's ridley turtle Inhabits iha'. ow water areas from Marsh Island to the Mississippi Delta in Louisiana. Coastal Louisiana appears to be an Important subadult and feeding habitat. The hawksbill turtle Inhabits reefs, shallow coastal areas , and passes In water less than 15 m deep. The leatherneck turtle Is the most pelagic marine turt le and may be found near the continental shelf edge. The loggerhead turtle occurs throughout the Gulf and has been observed as far as 500 miles offshore. It Is known to frequent natural and manmade structures. Including oil and gas platforms.

Brown pelicans are l is ted as endangered In Louisiana. Three brown pelican rookeries occur on Last Island '.Terrebonne Parish), North Island (St. Bernard Parish), and Queen Bess Island (Jefferson Parish), Louisiana. Endangered bald eagles Inhabit the Gulf coastal areas of Louisiana. The piping plover ut i l izes the beaches, sandflats, and dunes of Louisiana between September and March.

J . SreiOECQNQHIC ^

Tne offshore oil Industry Including oi l companies, dr i l l ing contractors, and oilf ield suppliers provide a major Input to Louisiana's economy. A member of ports In the Central and Western Gulf have developed Into Important centers for offshore support. The most active of these In Louisiana are (from east to west) Venice, Morgan City, Intracoastal City, and Cameron, Louisiana. The onshore support base for operations In West Cameron 240/231 Is Intracoastal City, Louisiana. As previously stated, no new employees will be required for this project, either as production crews or in support functions.

Exhibit 14 (8/13)

I I I . UNMQIErtblE ADVERSE EfiVIRWMLMTAL EFFECTS

A. WATER QUALITY

Development activities will temporarily reduce water quality adjacent to the location. This will Increase turbidity In a plume down-current from the work site. Released waters and a minor oil spill could also contribute to water quality degradation.

B. FFFFCTS OM MARINE OfDANISMS

Some organisms will be killed and some will be temporarily funct1*"ia11y Impaired as a result of development operations. The most affected groups will be plankton and benthos Immediately around the platform. Damans will be both mechanical and toxlcologlcal. These Impacts are considered to be localized, short term and reversible at the population level.

An oil spill could affect a broad spectrum of marine organisms. However, most effects would be localized and short tern. Any effects on mammals and turtles would be significant.

C. WETLANDS AND BEACH

In the unlikely event of a spill occurring and reaching shore, organisms 1n wetland and beach habitats could be killed or functionally Impaired. Human community disruption could also occur. Although all such effects would be localized, any effects on endangered species and/or critical habitats would be significant.

D. AIR DUALITY

The major Impact producing factors onwalr quality from OCS-related activity are due to combustion, evaporation, or venting of hydrocarbons. The air quality at the lease site will be degraded temporarily during operations, as a result from support vessels (boats and helicopters) as well as from the platform. Anticipated emissions are expected to be below MMS guidelines limits and air quality should return to normal once operations are measurably completed. Offshore activities probably will not affect onshore air quality because of the distance ritween the platform and shore. Air quality at the onshore base will be only Insignificantly reduced by onshore activities. Any such effect will be temporary.

E. CCtflERCIAL FISH I Re

The major Impact producing factors on fishing activities from the proposed operations Is production platform placement, OCS produced water discharges,

7

Exhibit U (9/13)

sal t - re lated oil s p i l l s , and underwater OCS obstructions such as pipelines and debris.

Oi l s p i l l s that contact the coastal marshes, bays, estuaries, and open Gulf areas with high concentrations of floating eggs and larvae have the greatest potential for damage to commercial f isher ies. The majority of tht G u l f ' s fishes art estuarine dependent. An o i l sp i l l could seriously affect coeaaerclal fisheries such as menhaden, shrimp, and blue crab that use these areas as nursery or spawning grounds.

One production platform with a surrounding 500 ft navigation<1 safety zone, may remove approximately 9 acrts of trawling spact, and underwater OCS obstructions cause gtar confl icts which r tsul t In such losses as trawls, shrimp catch, business downtime, and vessel damage.

Cotamerclal fishery resources may also be affected by the discharge of d r i l l i n g muds and produced waters. Dril l ing muds contain material toxic to ma ine fishes; however, th is Is only at concentrations four or five orders of magnitude higher than those found more than a few meters from the discharge point. Furthtr dilution *s extremely rapid In offshore waters.

The Installation of pipelines may contribute to salinity regimes, wattr current patterns, turbidity and/or wetland/seagrass loss, and, therefore, negatively Impact fishery resources.

In conclusion, although these factors Impact tht commercial f isheries Industries, tht level of Impact Is expected to be vtry negligible.

F . SHIP NAVIGATION

Very l i t t l e Inttiference can be expected between the platform and marine v e s s e l s utilized during development operations and ships that use estab­l i s h e d fairways. However, at night and during rough weather, fog, and heavy seas, ships not using established fairways could coll ide with the platform. Approved aids to navigation wi l l be Installed on tht platform and a l l marine vessels servicing these operations In accordance with USCG regulations.

G. CULTURAL RESOURCES

There Is only a small probability that an unknown cultural resource exists In the lease areas.

H. RECREATION AND AESTHETIC VALUES

The platform and marine vessels may represent an obstacle to some sport fisherman, but such an effect Is expected to be negligible and not per­manent.

Exhibit U ( 0 / 1 3 )

Even though existing regulations and orders prohibit Indiscriminate littering of the marine environment with trash, offshore oil and gas operations Involving men, machines, equipment, and supplies Is bound to result In some littering of the ocean. Human nature and accidents asso­ciated with offshore operations will contribute some floatable debris to the ocean environment which will eventually come ashore on major recre­ational beaches.

The effects that normal operations or a minor oil spill would have on any fish stocks Important to sport fishermen are also considered to be negligible.

A minor oil spill and/or non-petroleum floating debris could foul beaches Inshore of the lease area, the fouling of the beaches would be an aes­thetic detriment that could adversely affect recreation. Any effects on beach recreation could adversely affect tourism, and consequently, the local economy.
