EXPLORATORY DRILLING PLAN

MISSISSIPPI CANYON BLOCK 809, OCS-G 5868 MISSISSIPPI CANYON BLOCK 852, OCS G 8570 MISSISSIPPI CANYON BLOCK 853, OCS-G 5871

Exploratory drilling on these blocks will be accomplished

by drilling up to eleven (11) wells with a drillship MODU.

A typical MODU that will be employed for the proposed operations

is the SEDCO 471 Drillship MODU.

After drilling the required number of exploratory wells

to effectively evaluate the lease, and i f the wells are con

sidered to be productive, then a Plan of Development/Production

would be submitted for approval.

Should a well indicate the presence of hydrocarbon bearing

sands in commercially paying quantities, the well may be tempo

rarily abandoned according to the provisions of GOM-OCS Order No.

3 and any other requirements as specified by the District Super

visor. Additionally, approved DOT, United States Coast Guard

Navigational Aids shall be Installed where required following

temporary abandonment.

Upon completion of exploratory drilling, a platform may

be installed over thc location(s) for the development/production

phases. A separate platform installation application with

appropriate documentation would be submitted at that time.

Throughout the l i f e of the proposed project, a l l available

safeguards shall be utilized in an effort to prevent any possible

damage to the ecosystem.

Getty. Oil Company Is an active member of Clean Gulf Associates

(CGA). Should an upset occur at tbr* proposed project site, tbe

nearest $G|I base Is located at Grand Isle , Louisiana. The anti

cipated response time from Grand Isle, Louisiana, including

loadout of equipment, i s approximately twenty-four (24) hours.

Getty will be operating under EPA Gulf of Mexico General Permit

Number TX0085642 (PR 46 No. 64, 20284).

The following exhibits shall constitute the remainder of

this proposed Plan of Exploration:

1. EXHIBIT I — Louisiana CZM Consistency Certification

2. SHALLOW HAZARDS STATEMENT

The velocity analysis associated vith the seismic data

coverage on Mississippi Canyon Blocks 809, 852, 853 do not

indi a transition into high pressure sediments. As a

result of this an^ the absence of any nearby veil control,

a pressure nap v i l l not be included vith this Plan. Hovever,

i t could be assumed that the normal Gulf Coast pressure

gradient of .465 psi/ft. exists. Note that salt should be

seen close to the T.D. of each v e i l .

Therefore, Getty Oil Company i s of the opinion that the veil

locations identified herein are free from any knovn shallov

hazards.

3. PROPOSED TIMETABLE

Commencement of drilling activities are scheduled to begin on

or about October 15, 1983 at Mississippi Canyon Block 852.

Six locations have been chosen. These locations are based

on current available data. The decision to d r i l l any additional

we 11(8) (or a l l scheduled ve ) v i l l be based on that data

obtained from the f i r s t well. This includes drilling activities

at Mississippi Canyon Blocks 809 and 853. If operations do

commence on October 15, 1983, the f i r s t well would be completed

on or about December 15, 1983. Each well i s expected to

require an average of ninety (90) days to d r i l l . Thus, i f

al l wells were drilled consecutively, 2.7 years would be

required to complete the proposed project.

of

After drilling tbe necessary anmber of veils to effectively

evaluate the lease, the rig vould be released.

The proposed timetable le contingent upon.: (1) timely approve x

t|ie Plan %>T Exploration, (;*) actual reta* D-ar-at of tbe drilling

vessel, and (3)v..timely approval of the dril:.ng perir4. + (s '4M>>.

Getty Oil Company reserves the right to terminate :

exploratory drilling activities should the results of i> e ( .

or more veils indicate a lack of sufficient reserves to r&ofc

commencement of development activities and Jtirther reserves tbo

right to abandon the lease vithout further act 'ty.

Gm Dynamic Stationing:

1) Description

-Dynamic stationing control is provided ay an automatic station keeping (ASK) system specifically designed for positioning offshore dr i l l ing units. The system provides automatic control of the position and heading of the vessel through automatic control of the main and thruster propellers. The primary position reference system measures the vessel's position by means of an acoustic position indicator relative to a single acoustic beacon placed near the sea-floor dri l l ing position. Heading information is provided by the unit's gyrocompass. Control orders to the thrusters and propellers, in repsonse to deviations from desired position and heading, are automatically provided by a digital computer. Semi-automatic control of any or a l l thrusters and main propulsion ir provided by use of a "Joystick" at the operator's console, and thrusters can be manually controlled from the console individually.

The system ut i l izes redundancy throughout, forming tvo single-line systems Integrated vith monitors and sensors to automatically svitch control of the thrusters from one system to another in the event & component f a i l s .

The system l s composed of six position sensors (tvo acoustic, tvo taut vires and tvo riser angle indicators), tvo digital computers, tvo gyrocompasses, automatic svitching equipment, thruster control interface, and an operator control and display console. Methods are included to provide "Bumpless" transfer betveen position sensing systems. Continuous wind compensation is provided.

2) Components

a) ASK Svstem

The control system and sensors are fully redundant vith automatic svitching betveen alternative units.

The computer hss an automatic restart feature. The computer is programmed to use continuous input of vind apeed and direction to augment thrust requirements.

The entire computer control system, vertlcsi reference gyros, heading gyros, position sensors, control console, and printers are Isolated from ship's power by use of a redundant unlntersipttie power suppiy. The computers are digital vitn sufficient core storage to handle the dynamic positioning control system program, plus interface vith power management and data logging. Spare core v i l l be available to provide a thruster assist to mooring program.

I 4 I .

Redundant a;oustic positicm reference systens are provided ' to monitor vessel's position with respect to a fixed location ,' on the ocean floor. These systens are suitable for use during

operations in water depths fron 300 feet to 5,000 feet.

i ; • • / The acoustic systens consist of two beacons on the ocean

floor and four hydrophones nounted in the hull of vessel to providm redundancy In dynamic positioning. The hydrophones are extendable and retractable and suitably spaced for operations in water depths of 300 to 5,000 feet. Four hydrophones are centered around the noonpool. Installation and arrangement of beacons preclude masking of signals by the subsea wellhead assembly. Batteries in the beacons have a nlnimum l i f e of 60 to 120 days. Primary position reference is by an acoustic system that is capable of.monitoring vessel position relative to the wellbore. In the event of failure in the acoustic position reference system, the computer control system Is designed to sound an alarm and automatically transfer to either the ball joint r i ser angle signal or the taut wire angle signal. These two signals are back ups to the acoustic signal and priority is allocated at the discretion of the operator.

b) Thruster Svstem

(1) Thrusters

The thruster system consists of six (6) pairs of thruster units, f ive (5) located ln vertical structural wells and one (1) located in the skeg, as shown on Control Guidance Plans in conjunction with the main propulsion system. Each thruster pod is made up of two (2%- Bayior/Pleuger units rated at 850 horsepower each, situated along aide each other. Each pod operates in a fixed transverse direction with reversing ability to provide thrust in either port or starboard direction.

A Kort nozzle Is f itted around each propeller to prevent hydrodynamic Interference. Propellers are fixed pitch with blading designed for ahead and astern operation and are driven via gears through a DC motor placed In watertight pod above.

The skeg thruster units and their watertight pods containing motors, controllers, power and signal cables are installed as an Integral part of the skeg and hull . Access to the pods is obtained through a bolted plate manhole in the pod top located in the Ship's Service Generator Room Fla t . The other five pairs of thrusters are designed for vertical movement within the structural wells permitting positioning of the propeller below the hul l for dynamic positioning, within the well when the ship i s underway, and up through the deck for major overhaul.

- 50 -

Vertical movement la acconpliahed with hydraulic cylinders Access to the pods is obtained through a trunk extending above the deck.

The thrusters are capable of withstanding frequent

( reversals,in the direction of thrust without"damage to the gears, bearings, other nechanical parts cr power generating units. Provisions are nade for measuring rpm, and other operating characteristics .of the thrusters that deteimine the direction and magnitude of thrust output.

(2) Main Propulsion Systen

During the drilling node the main propuls.on systen shall be controlled automatically and operate in conjunction with the system for dynamic positioning.

The main propulsion system shall consist of twin units each comprising of a reduction gear driven by six (6) electric propulsion motors. The power supply shall be taken from the main generators and the total shaft horsepower output available shall be approxi' mately 4500 HP.

The ABS continuous marine propulsion rating for each motor wi l l be 750 HP. While in the dynamic stationing mode, the motors are paired in series to obtain more torque (resulting in 2250 HP output per shaft).

Propulsion motors shall be arranged four (4) forward and two (2) aft of each reduction gear (total 12 motors) to drive through a pinion gear configuration.

Locstion of Project: Mississippi Canyon Blocks 852 & 853 Operstion Schedule -Begin: October 1, 1983 End: October 1, 1985 Distsnce to Shoreline (aesn high water l i n e ) : Fifty-seven (57) Statute Miles

I I . Synopsis

The projected emissions derived ss a result of this review represent a maximum ( l i b e r a l ) assessaent for indicator pollutants. The findings of this asseesaent ind cate that the proposed eaissions herein are well below the exemption rotes and pose no aignificant iapact on the aabient a i r quality of the onshore environment. Based on this assessment, no further a i r quslity review is required.

IV. Exemption Formula

The projected emissions from operatione are to be compared with "exemption rules" for the f a c i l i t y location. I f the amount of these projected emissions is less than or equal to the emissions amount "E" for the air pollutant, the f e c i l i t y is exempt for thst a i r pollutant from further a i r quali ty rev i ew.

The following formulas pursusnt to 30 CFR Psrt 250 Sec. 250-57-1 (d)are used to determine exemption rates:

2/3 Fer CO; E-3400 D For TSP, S02, NOx, VOC: E-33.3D D* distsnce of the f e c i l i t y in statute miles from the closest onshore area

Based upon these exemption formulas, the following amission rstes were computed for Getty Oil HC Blocks 852 ft 853 Oistsnee from nearest onshore area ia fifty-seven (57) atatute miles.

The impacts associated with the proposed a c t i v i t y are considered minimal. These impacts are otherwise offset by the b e n e f i c i a l increese in biomass neer the pIetform/rig. These s t r u c t u r e s serve es a r t i f i c i a l reefs for marine communities by providing a substrate for epifauna to grow on. Pelagic f i s h then are e t t r a c t e d to these areas to feed on the attached organisms thereby r e s u l t i n g in greeter f i s h e r y yields in these arees.

2. Sh i pp i ng

The Louisiana Offshore Oil Port (LOOP or Superport) i s loceted 19 miles off of the Lafourche Parish shore and is approximately 75 miles northwest of the proposed pr o j e c t . The Port adds a new dimension in wsterborne commerce; the deepwster locstion allows large tankers used in international o i l trade to moor and offload v i a pipeline to on-land sto rage f a c i I i t i e s .

There are no shipping f s i r w s y s in or neer Blocks 852 snd 853. The c l o s e s t fsirway i s sppproximsteIy 43 miles due west of the proposed action. Consequently, the proposed ection w i l l not e f f e c t the operations of any shipping f a i r way, LOOP ope rations,or sny transit/snchorage areas.

3. Recreation

Many f i s h snd s h e l l f i s h sought s f t e r for commercisl vslue ere s l s o pursued for sport in coastal Louisiana. Ssltwster sport species include spotted eee trout, red drum, red snapper, FI orida pompano and tarpon. The offshore permanent s t r u c t u r e s provide highly productive a r t i f i c i a l reefs thet ere favorable f i a h i n g ereas for saltweter sport f i s h e r men. An area of high productivity for big game f i s h i n g is locsted epproximateIy three miles south of the project sree;the a c t i v i t i e s associated with t h i s project are not expected to a f f e c t t h i s area. Thus, the implementation of this p r o j e c t i s not expected to produce any edverse impecte on sport fishing.snd plessure booting; in f e c t , recreational potential w i l l be s l i g h t l y increased due to t h i s action.

There are no tea t u r t l e nesting areas in the coastal waters adjacent to Plequemine and Lafourche parishes ; therefore, no impacts are expected t> occur with respect to endangered or threetened sea t u r t l e s in the area.

c. Onshore Species (Endangered and Threatened)

-Americon a l l i g a t o r ( A l l i g a t o r m i s s i s s i p p i e n s i s ) This spscies is c u r r e n t l y c l a s s i f i e d as Threatened due to the " S i m i l a r i t y of Appearance 1 4 on the federal l i s t of endangered species in the coastal arees of Louisiana. Subsequently, twelve perishes currently are allowed to permit regulated harvests of a l l i g a t o r s in t h e ; r respective parishes; P l a quemine and Lafourche perishes are emong these. Stote laws govern the harvests and ellow the taking of a l l i g a t o r hides and meat during harvest seasons.

The American A l l i g a t o r is the only spec •»». . j r r e n t l y on the federel l i s t of endangered or threatened species thet i s commonly found in the coastal areas neer the project.

j ^ » I I I . UNAVOIDABLE ADVERSF IMPACTS

The env i ronmenta I cc n n quene es of the proposed project •re expected to bt minimal. Most impacts idontifiod w i l l be of a temporary nature and w i l l occur in ths immediate v i c i n i t y of tha operation. Therefore, no long term e f f e c t on the environment is expected.

Unevoidable adverse impacts i r ^ l u d e :

a. An increase in a i r pollutants l«- a r e s u l t of powe.* generation during d r i l l i n g and transportstion modes. However, en a i r q uality review has been conducted pursusnt to 30 CFft 250.57. The findings of t h i s review indi c s t e thst the projected emissions sre well below the exemption rotes and pose no s i g n i f i c s n t iapsct on the smbient s i r q u s l i t y of the onshore environment.

b. A temporary reduction in water quality due to the d i s posal of d r i l l c u t t i n g s , deck drsinsge end sanitary and domestic waste w i l l occur as a r e s u l t of t h i s action. During the disposal of d r i l l c u t t i n g s , an increase in t u r b i d i t y w i l l be evident as a r e s u l t of d r i l l i n g f l u i d s adhering to these p a r t i c l e s . Since tha a v a i l a b i l i t y of sunlight is sn iaportsnt f a c t o r in photosynthesis, i t hss been found thet increased t u r b i d i t v reduces photosynthesis. However, t h i s e f f e c t w i l l be short-term snd w i l l return to normal once the d r i l l i n g phase is coapleted. The additional sources of wster pollutants sre also expected to produce eiin'm.! snd short-term e f f e c t s on the wster q u s l i t y nesr the r i g . These pollutants sre regulated by the U.S. Environmentai Protection Agency's e f f l u e n t ouidelines (40 CFR Part 435) for o i l snd gas e x t r a c t i o n . Con. ormence to these guidelines w i l l be carried out throughout the project period.

c. Burial of immobile benthic organisms w i l l occur during the discharge of d r i l l c u t t i n g s . D r i l l cuttings sccumulste on the tea f l o o r covering an area of approximately 150 feet in diameter; in the affected area the impaet is loeelized and d i s s i p a t e s over time by currents. Mobils benthic organisms from the surrounding see f l o o r adjuat rather rapidly to these changes and build homes on top of the c u t t i n g s . Hithin months the affected ores i s again f l o u r i s h i n g with new benthic communitiee (Zingulo et s l , 1977). Thus, the impscts asaociated with t h i s a c t i v i t y w i l l be short-term end

hem, generality one quarter nautical at i I e in radius. The eep areas of the Gulf are not primary trawling areas.

Jhe GCS Ac t Amendments provide for a IF i s he rman ' s Contingency Fund financed from o i l revenues to compensate commercial fisherman for losses or damage to gear r e s u l t i n g from o i l industry operations.

The impacts aesociated with the proposed a c t i v i t y are considered minimal. These impacts are otherwise o f f s e t by the b e n e f i c i a l increase in biomass neer the pI atform/rig. These s t r u c t u r e s serve as a r t i f i c i a l reefs for marine comnunities by providing a substrate for epifauna to grow on. Pelegic f i s h then sre a t t r a c t e d to these areas to feed on the attached organisms thereby resulting in greater f i s h e r y yields in these s r e s s .

2. Sh i pp i ng

The L o u i s i a n a Offshore Oil Port (LOOP or Superport) is locsted 19 miles off of the Lafourche Parish shore snd ia approximately 70 miles northwest of the proposed p r o j e c t . The Port sdds a new dimeneion in waterborne commerce; the deepwater location allows large tankers used in international o i l trade to moor and offload v i a pipeline to on-I and sto rage f a c i I i t i e s .

There are no shipping fairways in or .mr Block 809. The c l o s e s t fairway is sppproximateIy 45 miles due west of the proposed action. Consequently, the proposed action w i l l not a f f e c t the operetions of any shipping fairway, LOOP operations,or sny transit/anchorage arees.

3. Recreation

Saltwater sport species include spotted ses trout, red drum, red snapper, F l o r i d a pompano and tarpon. The offshore permanent s t r u c t u r e s provide highly productive a r t i f i c i a l r m f s that are favorable f i s h i n g areas for saltweter sport f i s h e r men. An area of high productivity for big gems f i s h i n g i s looated approximately f i v e miles south of the project eree;the a c t i v i t i e s essociated with t h i s project are not expected to a f f e c t t h i s s r e s . Thus, the implementation of

4. Cultural Resources

There are no shipwrecks or other i d e n t i f i a b l e c u l t u r a l or archeoIogica I features in Mi s s i s s i p p i Canyon Block 809. (USDI, BLM OCS Sale 62 Visual #4).

The proposed location is seaward of the high probability line f o r c u l t u r a l , h i s t o r i c or p r e - h i s t o r i c resources (USDI,RegionaI Impact Stmt., Visual # 11). Therefore, the proposed a c t i o n is not expected to produce any s i g n i f i c a n t impacts on these resources.

5. E c o l o g i c a l l y S e n s i t i v e Features

The proposed project is located approximete Iy 57 miles from the Plaquemine Perish coast. This coastal area i s cherecterized by numerous acres of marsh which provide habitat f or a variety of w i l d l i f e and also serve as primary nursery grounds for f i s h snd s h e l l f i s h . Along th i s coastal area is found the Pess A Loutre W i l d l i f e Management Area and the Delta National W i l d l i f e Refuge these areas are more than 60 miles from the proposed a c t i v i t y . The Lafourche and Jefferson P a r i s h coastal areas are approximately 90 to 100 miles northwest of the proposed pr o j e c t . The coestal areas of these parishes include envi-onmenaI Iy s e n s i t i v e areas such as the Wisner State W i l d l i f e Management Area and the ber r ier i s l a n d s .

The Wiener Stete W i l d l i f e Manegement Aree conteins 21,621 acres of marsh. This area serves many conservation and preservation functions in w i l d l i f e management. The Grand I s l e - Grsnd Terre Islands snd the Timbelier Islands sre important geological features along the Louisiana coast. These b a r r i e r islands are extremely importent in regulating and maintaining water exchange and s a l t water balance between the Gulf end the baye. They also reduce etorm surge and wave ac t i o n on the marshes snd bsys behind the islands snd provide nesting areas for msny shorebirds snd ses birds. The propoeed oction is 90 to 100 miles south of these envi ronmen ts I I y sensi ve areas.

The proposed project, located 57 n i l e s off the Pl a -juemine P a r i s h coast, is within the range of five endangered ipecies of whales, three species of endangered t u r t l e s and two species v.© f threatened t u r t l e s . Onshore the Plaquemine Parish area is within the range of the endangered bald eagle and the threatened American a l l i g a t o r . The onshore area east of Bayou Lafourche in Lafourche Parish i s within the range of the Brown P e l i c a n .

a. Whales (Endangered)

-Sei whale (Balaenoptera b o r e a l i s ) This species is a possible winter resident of the Gulf of Mexico.

-Fin whale (balaenoptera physalus) This species is s possible winter resident of the Gulf of Mexico.

-Blue whale (balaenoptera musculus) This species is uncommon to the Gulf of Mexico.

-Humpback whale (Megaptera novaeangliae) This species is a possible winter resident of the Gulf of Mexico.

-Sperm whale (Physeter catodon) The most common of the endangered whales to occur in the Gulf of Mexico.

Migretory patterns of the whales l i s t e d above are not directly known. I t is presumed that these species occur mainly in the deeper waters of the Gulf of Mexico. The proposed p r o j e c t is considered a deep water project ,however, the proposed project is not expected to adversely affect whole populations or migratory patterns.

b. Turtles (Endangered and Threatened)

-Kemps A t l a n t i c rid l e y (Lepidochelys kempii) The shrimping grounds of the northern Gulf of Mexico is a primary feeding area for t h i s endangered species.

-Hawksbill t u r t l e (Eretmochelys imbricata) An endangered species that may occur in the coastal waters of Louisiana.

-Leetherback t u r t l e (Dermochelys coriacea) The rsnge of t h i s endsngered species is usually the deeper wsters of the Gulf of Mexico; however, observations hsve been msde of large

I

numbers o(f leatherbacks feedinp on j e l l y f i s h in inshore waters during summer (USDI, EIS, OCS Sale 58A, pg. 62.).

-Green t j u r t l * (Chelonia mydas) and the Loggerhead t u r t l e (Caretta c a r e t t a ) are l i s t e d as threatened and occur in the Gulf of Hexico waters.

There are no sea t u r t l e nesting areas in the coastal waters adjacent to Plequemine and Lafourche parishes ; therefore, no impacts are expected to occur with respect to endangered or threatened sea t u r t l e s in the area.

c. Onshore Species (Endangered and Throatened)

-American a l l i g a t o r ( A l l i g a t o r m i s s i s s i p p i e n s i s ) This species is currently c l a s s i f i e d as Threatened due to the " S i m i l a r i t y of Appearance" on the federal l i s t of endangered species in the coastal areas of Louis i a n a . Subsequently, twelve parishes currently are allowed to permit regulated harvests of a l l i g a t o r s in t h e i r reepective parishes; P l a quemine and Lafourche parishes are among these. State laws govern the harvests and allow the taking of a l l i g a t o r ii ides and meet during harvest seasons.

The American A l l i g a t o r is the only species currently on the federel l i s t of endangered or threatened species that i s commonly found in the coastal areas near the project.

-Southern Bald Eagle (Haliaeetus Iucoc%pha I us ) Plaquemine and Lafourche parishes are within the range of the bald eagle. Nesting s i t e s ore found in the treee near watei— bodies.

-Brown Pel i c a n (Pelicanus o c c i d e n t a l i s ) There is a small colony of brown pelicans that nest in the Queen Bess I s l s n d and Grand Terre Islands area of Southern B a r r a t a r i a Bay. This area is approximately 90 miles northwest of the proooeed pr o i e c t .

The proposed project does not require any additional onshore f a c i l i t i e s ; therefore, there are no expected impacts on the habitat of these onshore endsngered or threatened species as a r e s u l t of t h i s action.

B. Socio-economic- Not applicable at t h i s time.

) 7."j I I I . UNAVOIDABLE ADVERSE IMPACTS

The environniental consequences of the proposed project aro expecterd to be minimal. Most impacts i d e n t i f i e d w i l l be of a temporary nature and w i l l occur in the immediate v i c i n i t y of the operation. Therefore, no long term e f f e c t on the environment is expected.

Unavoidable adverse impacts include:

e. An increase in a i r poi lutants is a r e s u l t of power genei— ation during d r i l l i n g and transportation modes. However, an a i r q u a l i t y review has been conducted pursuant to 30 CFR 250.57. The findings of t h i s review indicate that the projected emissions ere weil below the exemption retes and pose no s i g n i f i c a n t impact on the ambient a i r quality of the onshore environment.

b. A temporary reduction in water q u s l i t y due to the d i s posal of d r i l l cuttings, deck dra'.t'.fce end s a n i t a r y and domestic waste w i l l occur as a resul of t h i s action. During the disposal of d r i l l c u t t i n g s , an i i-rease in t u r b i d i t y will be evident es a r e s u l t of d r i l l ng f l u i d s adhering to these p a r t i c l e s . Since tS« a v a i l a b i l i t y of sunlight is an important factor in photosynthesis, i t has been fcund that increased t u r b i d i t y reduces photosynthesis. However, t h i s effect w i l l be short-te./i and w i l l return to normal cnce the d r i l i i n g phase is comp sted. The additional sources of water pollutants are also expected to produce minimal and short-term e f f e c t s on the water quality near the r i g . Ihese pollutants are regulated by the U.S. Environmental Protection Agency's e f f l u e n t guidelines (40 CFR Part 435) for o i l and gas e x t r a c t i o n . Conformance to these guidelines w i l l be carried out throughout the project period,

c. Burial of immobile benthic organisms w i l l occur during the discharge of d r i l l c u t t i n g s . D r i l l cuttings accumulate on the see f l o o r covering an area of approximately 150 feet in diameter; in the affected area the impact is l o c a l i z e d and d i s s i p a t e s over time by currents. Mobile benthic organisms froa the surrounding sea floor adjust rather rapidly to thesv' changes and build homes on top of the c u t t i n g s . Within months the effected area is agein f l o u r i s h i n g with new benthic communities (Zingula et a l , 1977). Thus, the impacts associated with t h i s a c t i v i t y w i l l be short-term and

- 10 -

local rzed

4. There w i l l be a temporary loss of approximately f i v e acres 12 hectares) of sea space that w i l l be unavailable for commercial f i s h i n g . I f the wells are economically producible then eventual future development/production operations would have a more permanent e f f e c t . However, there are some posit i v e e x t e r n a l i t i e s associated wit. the proposed a c t i v i t i e s that would, in the long run, benefit commercial and recreation f i s h i n g ; these are:

-An increase in biomass near the rig/platform, thus, r e s u l t ing in higher productivity.

-Offshore structures may serve as navigation aids and during mechanical breakdowns or inclement weether provide refuge for boat operators.
