10. Discharges A l l discharges from the Eugene Is land 374 l o c a t i o n w i l l comply with the Environmental Protect ion Agency NPDES General Permi t f o r the Gulf o f Mexico.

Eugene Island 374 Plan of Explorat ion OCS-G-7743

The estimated discharge r a t e i s a maximum of 1,000 bar re l s per hour.

Any d r i l l i n g mud, d r i l l c u t t i n g s and or other so l id s w i l l no t be discharged i n t o the Gulf unless the t o x i c i t y i s measured by the EPA " D r i l l i n g Flu ids T o x i c i t y Test" i s above the 30,000 ppm l i m i t a t i o n . I n a d d i t i o n , no discharge tha t causes a sheen t o appear on the surface o f the water w i l l be made. (See Attachment "E") .

Any d r i l l i n g f l u i d s contaminated w i t h o i l and any s o l i d domestic wastes w i l l be t ranspor ted t o shore f o r proper disposal at an au thor ized disposal s i t e .

EAOI believes t h a t t h i s i s not a known H s area because i n t he d r i l l i n g of the OCS-G-3575 Well #1 , d r i l l e d by Texaco on Eugene Island 374 i n 1982, no H s was encountered.

I t i s estimated t h a t over 38 m i l l i o n res iden ts of the Gulf coastal states have a major i n t e r e s t i n wate r - re la ted and water enhanced r e c r e a t i o n a l a c t i v i t y . Approximately two- th i rds of the G u l f shorefront i s composed of beach and there is one motor boat f o r about every 21 people l i v i n g i n the Gulf Region. More s p e c i f i c a l l y , approximately 13.5 m i l l i o n people, or 35 percent of the Gul f States popula t ion , l i v e i n the area most d i r e c t l y a f fec ted by Gulf a c t i v i t y , and about one - th i rd o f the reg is te red boats are l i k e l y candidates f o r marine rec rea t iona l a c t i v i t y (16 ; or g rea te r ) .

I t i s reasonable t o expect t ha t e x p l o r a t i o n and product ion on blocks leased i n the Central Gulf o f Mexico w i l l r e s u l t i n some ocean l i t t e r and could lead t o one major o i l s p i l l , and that s p i l l and d e b r i s could be c a r r i e d by wind, wave and currents to i n t e r a c t w i t h major s h o r e f r o n t r ec rea t iona l beaches throughout t he Gulf of Mexico.

O i l s p i l l s contacting a t u r t l e n e s t i ' beach incubation or hatching periods could cause s i g n i f t u r t l e m o r t a l i t y ( F r i t t s and McGhee, 1981) and of ^ o i . w i l s p i l l s could have a serious impact on j u v e n i l e t u r v es as sea t u r t l e s can attempt t o swallow any object of appropriate size, such as t<*r b a l l s , which could r e s u l t i n s i g n i f i c a n t t u r t l e m o r t a l i t y . There i s a 2 percent probabi t t y of one or more o i l s p i l l s occurring and contacting see .urtlea nesting h a b i t a t and less than a 10 percent p r o b a b i l i t y of one or more o i l s p i l l s occurring and contacting sea t u r t l e foraging areas o f f the c e n t r a l Louisiana coast.

The impact on various endangered and threatened species w i l l depend on the nature of the s p i l l , weather conditions, proximity of s p i l l s t o species, tolerance f o r o i l of species, and the response t i n e and effectiveness of the o i l s p i l l cleanup and containment services. Given these var j • ..les, the impact on the various endangered or t b ^atened species w i l l vary from l i t t l e or no e f f e c t t o dry serious.

The experience of o i l and gas exploration i n the Gulf of Mexico indicates t h a t there i s a small p r o b a b i l i t y of occurrence of an o i l s p i l l . EAOI, as a prudent operator, w i l l take the necessary precautions t o reduce the p r o b a b i l i t y of o i l s p i l l s . EAOI's proposed operations should pose no t h r e a t t o any endangered or threatened species.

IV. UNAVOIDABLE ADVERSE IMPACTS

The proposed d r i l l i n g a c t i v i t i e s i n Eugene Island Block 374 w i l l r e s u l t i n the discharge of d r i l l i n g mud and c u t t i n g s i n t o the waters of the Gulf. The disposal of d r i l l i n g f l u i d s aiay r e s u l t i n minor decreases i n primary p r o d u c t i v i t y due t o whe m o r t a l i t y or f u n c t i o n a l impairment of plankton, benthic organisms, seagrasses, and algae i n areas of high t u r b i d i t y . A large o i l s p i l l i s very u n l i k e l y but could r e s u l t i n lo c a l i z e d severe m o r t a l i t i e s , s e l e c t i v e and functional impairment of plankton communities, thereby a l t e r i n g the community s t r u c t u r e f o r an unknown period of time.

D r i l l i n g a c t i v i t i e s corld cause an increase i n the t u r b i d i t y of the affected waters f o r the duration of the a c t i v i t y period. A t u r b i d i t y plume, several hundred yards i n length, could also be created by the discharge of d r i l l c u t t i n g s and the adherent d r i l l i n g f l u i d s . This, however, would only a f f e c t waters i n the immediate v i c i n i t y of the r i g . The discharge of treate d sewage from the r i g would increase the levels of suspended solids, n u t r i e n t s , c h l o r i n e , and BOD i n a small area near the discharge p o i n t s .

A i r emissions from combustion of diesel f u e l i n r i g engines, boat engines and helicopters can a f f e c t the a i r g u a l i t y near the proposed operations s i t e s and near the onshore t r a v e l routes. I n most cases, the emissions w i l l be l o c a l i n nature and w i l l be quickly dissipated by c l i m a t i c conditions.

Catastrophic events such as o i l s p i l l s and blowouts have the pot e n t i a l t o create localized a i r q u a l i t y problems. Degradation of onshore a i r q u a l i t y i s not l i k e l y t o occur and i s not expected due to the low number of expected s p i l l s , probable distance from shore (more than 3 miles and very l i k e l y f a t h e r ) , rapid dispersion or breakup associated with o i l s p i l l s and the turbulent v a r i a b l e winds offshore. Papid dispersion of evaporative emissions from these sources i s expected.

I f i blowout resulted i n a f i r e , s u b s t a n t i a l l e v e l s of THC, NO SO CO and TSP would be emitted. Local a i r would be seOerefy degraded f o r the duration of the f i r e . The extent of degradation i s indeterminate, but i t i s u n l i k e l y t h a t i t vould be high enough to a f f e c t land resources or human health.

The proposed exploration a c t i v i t i e s are not expected t o harmfully a f f e c t water q u a l i t y , i n t e r f e r e with commercial f i s h i n g operations, recreational a c t i v i t i e s or shipping t r a f f i c
