Envi ronment;. I Safeguards

(1) General

The goal of t h i s Exploration Plan i«3 the gathering of more information on the geology cf the lease areas, i n a safe manner, with minimal di s r u p t i o n of the environment. Various r u l e s , regulations, codes, laws and practices have been developed over the years, which w i l l a ssist f : operator t o conduct operations in t h i s manner. 30 CFR . Subpart C s p e c i f i c a l l y deals with the environmental sarcguerds and safety of the d r i l l i n g and production operations. The regulations are s t r i c t l y adhered t o by Samedan.

Environmental safeguards are b u i l t i n t o the operations i n several ways: i n the o r i g i n a l design of equipment and system of operations, i n the t r a i n i n g of personnel, i n the preparation of procedures f o r operations and also i n the procedures and a v a i l a b i l i t y of equipment f o r remedial actions i n cases of emergencies.

Operations w i l l be conducted under the conditions described on the Application f o r Permit to Discharge on f i l e w i t h th»" Minerals Management Service. Samedan conducts monthly t - ^ t -t o ensure t h a t l i q u i d wastes discharged i n t o the Gui Mexico comply w i t h E.P.A. Regulations.

(2) Environmental Safeguards i n the Design

The d r i l l i n g u n i t i s b u i l t to prevent p o l l u t i o n of the of Mexico by u t i l i z i n g a system of curbs, gutters and surface drains which d i r e c t a l l f l u i d s to a containment system. This system recovers hydrocarbons before water i s discharged i n t o the Gulf of Mexico.

Li q u i d waste material, including sewage from the l i v i n g quarters, w i l l be treated i n a Minerals Management Service approved sewage plant on the d r i l l i n g u n i t p r i o r t o discharge i n t o the ocean. Solid waste materials are compacted and transported t o shore f o r disposal.

D r i l l i n g operations are monitored by the Samedan representative on board. Mud and d r i l l c u t t i n g s w i l l be treated t o remove o i l p r i o r t o discharge i n t o the Gulf of Mexico. D r i l l i n g mud i s sampled and tested f o r t o x i c i t y according t o EPA LC50 standards. Items t h a t cannot be treated properly w i l l be transported t o shore f o r disposal.

(3) Training of Personnel i d Procedures

Regular t r a i n i n g of operations personnel i s a necessary complement to the p o l l u t i o n prevention features in the design of equipment and operations. Operator awareness i s achieved by regular t r a i n i n g and enforcement of procedures. The d r i l l i n g u n i t i s inspected d a i l y . A procedure f o r the r e p o r t i n g of and dealing with o i l s p i l l s has been established by Samedan i n accordance with the requirements of 30 CFR 250 Subpart C, which i s incorported i n Samedan's " O i l S p i l l Contingency Plan".

C. Safety Features

As i s the case with the environmental safeguards, safety aspects must be a combination of design, operator awareness and the a v a i l a b i l i t y of s u i t a b l e emergency equ:pment. Over t r years, the O i l Industry and the Federal Government has issued 1 considerable number of standards, recommended practices and laws governing minimum requirements. Design of equipment f o r Same<i*n's operations requires the ap p l i c a t i o n of a l l available standards i n the s t r i c t e s t manner. The most important of these are l i s t ' a below:

...OSHA

...OCS Orders of the Minerals Management Service

...API Standards and Recommended Practices

...ASME Codes

...ASTM Standards

...ANSI Standards

...AISC

...American Welding Society

...NFPA (NEC)

safety systems are incorporated i n the design of equipment and operational procedures as required by the OCS Orders of the Minerals Management Service. 30 CFR 7 0 Subpart D s p e c i f i c a l l y provides d e t a i l e d information on the d r i l l i n g operations and Samedan adheres s t r i c t l y t o those rules and regulations.

Automatic gas and f i r e detection systems are incorporated i n the u n i t t o alarm operations personnel i n case of emergencies. Equipment t o deal with emergencies ( l i f e vests, r a f t s , buoys, f i r e extinguishing equipment, l i f e boats. etc.) i s located s t r a t e g i c a l l y on the d r i l l i n g u n i t . Frequent t r a i n i n g sessions are held t o keep operations personnel a l e r t and f a m i l i a r w i t h procedures and operating i n s t r u c t i o n s f o r equipment.

A l l t l cse wastes w i l l be t r ted p r i o r t o discharge i n t o the sea t o ensure a minimal imp .:t on the environment. I n cases where s a t i s f a c t o r y t r e a t i n g ca-not be accomplished, wastes w i l l be col l e c t e d and brought to shore f o r c sposal. The f o l l o w i n g figures show approximate q u a n t i t i e s f o r wastes i n t h i s category:

D r i l l Cuttings 650 tons per w e l l D r i l l i n g F l u i d 7,000 bar r e l s per w e l l Sanitary/Sewage E f f l u e n t 4,000 gallons per day Cooling Water 1,000,000 gallons per day

Ernies)ons discharged i n t o the a i r during the d r i l l i n g phase w i l l be p r i m a r i l y associated w i t h power generation. The fol l o w i n g table l i f t s emissions during the d r i l l i n g operations (based upon Table 3.3.3-' oi EPA Publication AP-42):

Emission Factor in o/hp-hr

Tota l emissions can be found u t i l i z i n g the formula p erted i n EPA Publication PB-272-268:

"Emission Rate = Emission Factor X Total Well Footage X 60 h p - h r / f t "

Four w e l l s are t o be d r i l l e d i n 1990 with t o t a l ''ootage of approximately 68,800'. The fol l o w i n g emissions estimate (ton/yr) applies f o r the d r i l l i n g of the wells:

NOx S0X HC CO Pa r t i c u l a t e s

63.70 4.23 5.05 13.78 4.55

C. Exemption Test

"ne Rules and Regulations defined i n the Federal Register .57 of March 7, i960 require t e s t i n g against the emission

e. p t i o n amount as follows:

E •-- 3,4000 2/3 f o r CO

and

E = - 3D f o r t o t a l suspended partic u1.-..e--

For t h i s l o c a t i o n , a distance of i;5 tulles appli.v*.. ^h is makes the exemption amount as follows:

E = 23,072.25 Tons/yr. f o r CO

and

E =* 832.5 Tons/yr. f o r SOx, NOx, HC and P a r t i c u l a t e s

The calculated amounts f o r both CO and the t o t a l suspended p a r t i c u l a t e s are below the exemption amount. Therefore, f u r t h e r a i r q u a l i t y review i s not required f o r the proposed expl o r a t i o n a c t i v i t i e s i n the lease areas.

D. Transportation

Since t r a n s p o r t a t i o n requirei .ts are combined f o r Sameaan's operations i n the various tlocks i n the v i c i n i t y , i t is d i f f i c u l t to quantify the exact c o n t r i b u t i o n to the t o t a l emissions as a res u l t of t h i s exploration.

Typical f i g u r e s tor emission fron crew boats and supply boats using approximately iooo gallons of f u e l per day are as follows (based on EPA Emission f a c t o r s ) :

B. DESCRIPTION PROPOSED ACTION

1. Modes. Routes and Frequency of Support Vessels/Helicopter

Helicopter, work boat and crew boat are the three moder- of tr a n s p o r t a t i o n which w i l l be u t i l i z e d t o take personnel an.' supplies to the d r i l l i n g r i g area. Samedan w i i l use a shore base i n Grand I s l e , Louisiana as the base of operation f o r a l l three modes of tr a n s p o r t a t i o n .

A h e l i c o p t e r i s expected to make one or two t r i p s t o the r i g per day during the d r i l l i n g . During production t h i s frequency i s expected to drop t o ons t r i p per month.

The route u t i l i z e d by each mode w i l l normally be i n a s t r a i g h t l i n e from the shore base t o the p l a t f o r a l o c a t i o n . Whenever pos« ibl«, trans p o r t a t i o n of supplies and personnel i l l be combined with requirements of other ac\_ v i t i e s i n the area.

2. OnshPre Support frise

Samedan plans t o use an onshore base i n Grand I s l e , Louisiana from where tran s p o r t a t i o n of personnel, equipment, and supplies i s coordinated, as described i n the Plan.

No expansion of t h i s e x i s t i n g base i s anticipated as a r e s u l t of t h i s a c t i v i t y .

3. New Suppprt F a c i l i t i e s

The proposed action w i l l use e x i s t i n g support f a c i l i t i e s as described i n the Plan. Addition of new support f a c i l i t i e s w i l l not r e s u l t from t h i s action.

C. DESCRIPTION OF AFFECTED ENVIRONMENT

1. Physical and Environmental Parameters

a. Commercial Fishing

A representation of the coastal zone and offshore f i s h e r i e s i s shown on the Visuals of the Environmental Impact Statement prepared f o r OCS Sales 188 and 122. Commercial f i s h e r y resources are described i n t h i s Environmental Impact Statement.

Landings of a l l f i s h e r i e s i n the Gulf waters of the U.S. i n 1985 accounted f o r 38% or 2.4 b i l l i o n pounds and 26% or $596 m i l l i o n of the t o t a l U.S. catch.

The Gulf f i s h e r y i s dominated by the s h e l l f i s h e r i e s : shrimp, crabs, and oysters (with smaller amounts of clam and scallo p s ) , usually worth three or four times more than the much greater volume of f i n f i s h . The shrimp f i s h e r y i n the Gulf area includes brown, white, and pink shrimp. These are taken almost exclusively by t r a w l f i s h i n g , i n depths ranging from 2 t o 73 meters. Other shrimp taken commercially are the •ea bobs and royal reds.

Commercially important species of shrimp, the most common being brown shrimp and white shrimp, are taken i n the v i c i n i t y of Vermilion Block 266. Landings of shrimp i n the Gulf of Mexico average approximately 230 m i l l i o n pounds per year.

F i n f i s h volume f o r the Gulf states i s dominated by menhaden. I t i s number one i n both volume and value f o r the Gulf States. Landings i n 1985 were 1.9 b i l l i o n pounds, valued a t $67 m i l l i o n .

On the Gulf coast as a whole, the usual ranking of tha most important commercial fishes i s as shown below:

By Volume: By Value:

Menhaden Mullet Croaker Groupers Spanish Mackeral Spotted Seatrout Red Drum Flounders Black Drum King Whiting White Seatrout Sheepshead

Menhaden Red Snapper Mullet Croaker Groupers Pompano Spanish Mackeral Red Drum Flounders King Mackeral Black Drum White Seatrout Sheepshead

The proposed action w i l l not a f f e c t commercial f i s h i n g i n the area. A d e t a i l e d discussion of commercial f i s h i n g and the impact of o i l and gas a c t i v i t i e s i s found i n the FETS f o r OCS Lease Sales 110 and i n the FEIS f o r Sales 118 and 122.

b. Shipping

There are no fairways, t r a n s i t zones, or anchorage areas i n the v i c i n i t y of the proposed action.

c. Small Craft Pleasure Boating, Sport Fishing and Recreation

The proposed a c t i v i t y w i l l take place approximately 50 miles from the shore. Aside from damage caused by o i l s p i l l s , there i s considerable evidence t h a t o i l and gas operations have a favorable impact on f i s h i n g a c t i v i t i e s since str u c t u r e s act as breeding grounds and a r t i f i c i a l r e e f s. No long term e f f e c t , however, i s expected from these exploratory a c t i v i t i e s . The proposed a c t i v i t y i s not expected t o p o s i t i v e l y or negatively a f f e c t small c r a f t boating a c t i v i t i e s or r e c r e a t i o n a l a c t i v i t i e s .

d. E c o l o g i c a l l y Sensitive Areas

The lease area i s not si t u a t e d near an area of b i o l o g i c a l s i g n i f i c a n c e , as determined by inspection of Visual No. 4 of the Final Environmental Impact Statement f o r Lease Sales 118 and 122.

e. Existing Pipelines/Cables

There are 3 Chevron pipelines which cross t h i s block.

f. Other Mineral Uses

No other known mint deposits of commercial importance occur with the lease area.

g. Other Dumping Grounds

No approved ocean dumping s i t e s e x i s t i n the v i c i n i t y of the lease area.

h. Endangered/Threatened Species

Several federal l i s t e d endangered and threatened species inhabit the coastal and offshore area of the Gulf region. Six endangered marine mammals ( f i v e whales and the Florida manatee) , the key deer, two threatened and three endangered marine t u r t l e s , the threatened a l l i g a t o r and endangered crocod i l e , and seven endangered species of b i r d s were selected as representative of endangered and threatened species t h a t could be affected by offshore or onshore a c t i v i t i e s r e s u l t i n g from OCS o i l ind gas development i n the Gulf.

No f e d e r a l l y l i s t e d endangered plant species are known t o occur i n the Central Gulf area.

The impact producing agents which could a f f e c t endangered species i n the Central Gulf include OCS-related o i l s p i l l s and disturbance from onshore construction. I t i s u n l i k e l y t h a t OCS-related o i l s p i l l s w i l l impact endangered species or t h e i r h a b i t a t i n the Central Gulf due t o the low p r o b a b i l i t y t h a t a s p i l l would contact endangered species h a b i t a t w i t h i n ten days of an o i l s p i l l . No onshore construction i s expected t o occur near endangered species h a b i t a t as a r e s u l t of t h i s development. This development i s expected t o have a very low l e v e l of impact on endangered

species and no s i g n i f i c a n t e f f e c t s on t h e i r populations or habitats i n the Central Gulf.

Due t o the location of the proposed action i t i s u n l i k e l y t h a t threatened and endangered species w i l l be affected. A detailed discussion of threatened and endangered species i s found i n the Final Environmental Impact Statement fo r the Gulf of Mexico, published by the Minerals Management Service f o r OCS Lease Sales 118 and 122.

Socio-Economic Parameters

As described i n Section B.2 of t h i s Environmental Report and i n the Plan, no expansion of the e x i s t i n g shore base f a c i l i t y i s expected as a r e s u l t of t h i s action. Therefore, no new employment i s expected as a r e s u l t of the proposed ac t i o n .

D. UNAVOIDABLE ADVERSE FN'VIRONMFNTAL EFFECTS

The impacts on the various systems have been discussed i n Section C of t h i s Environmental Report. In general, i t can be stated t h a t a l l unavoidable adverse impacts which r e s u l t ftom routine operations w i l l be r e l a t i v e l y l o c alized and of short duration. These impacts, however, w i l l be followed by unhindered natural recovery w i t h i n a r e l a t i v e l y short time period (EIS Lease Sales 118 and 122.)

These impacts include:

...Temporary reduction i n water q u a l i t y due t o discharges during the d r i l l i n g operations.

...Short term e f f e c t and possible k i l l i n g of source plankton and benthos in the immediate v i c i n i t y of the platform.

...Temporary reduction i n a i r q u a l i t y during the d r i l l i n g operations.
