10. Hydrogen Sulfide

Elf Aquitaine Operating, Inc. has requested i n the Revised Plan of Exploration and i n accordance with 30 CFR 250.67(c) that the Minerals Management Service classify the area i n which the proposed operations w i l l take place. South Timbalier 226, as a zone where the absence of H2S has been confirmed.

EAOI believes that this area i s not a known H2S area because i n the d r i l l i n g of the South Timbalier 205 and 206 wells d r i l l e d by EAOI, no H S was encountered. In the approval l e t t e r for the revised POE for South Timbalier 226 dated May 26, 1989, this area was classified as a zone where the absence of H S has been confirmed.

11. Projected Air Emissions

An Air Quality Review for South Timbalier 226 i s included as Attachment "F".

12. Environmental Report

An environmental report for thi s location i s included as Exhibit "G".

13. Onshore Base

South Timbalier 226 i s located approximately 50 miles from the coast of Lafourche Parish, Louisiana where the water i s approximately 180 feet deep. A v i c i n i t y map showing the relationship of Block 226 to the shoreline and onshore base i s included as Attachment "A".

The proposed a c t i v i t i e s w i l l u t i l i z e a support base at Galveston, Texas. The base provides 24-hour service, a radio tower with phone patch, dock space, office space, a parking l o t , equipment and supply storage space, drinking and d r i l l water, •tc . The proposed production a c t i v i t i e s w i l l help to maintain this baae at i t s present level of a c t i v i t y . No expansion of the physical f a c i l i t i e s or the creation of new jobs is expected to result from the work planned i n conjunction with Block 226.

DEVELOPMENT OPERATIONS COORDINATION DOCUMENT

I . INTRODUCTION

Elf Aquitaine Operating, I n c . , Houston, Texas, plans to conduct a development program i n South Timbalier 226, Lease OCS-G-6771. This report i s submitted w i t h the I n i t i a l Development Operations Coordination Document (DOCD) i n accordance with the regulations of 30 CFR 250.34 and guidelines published November 20, 1980, and October 12, 1988.

I I . DESCRIPTION OF PROPOSED ACTIONS

Chevron Corporation and Offshore Bechtel Associates, L td., obtained South Timbalier Block 226 i n Lease Sale 81 on June 1, 1984.

Gulf Corporation f i l e d an I n i t i a l Plan of Exploration whereby they proposed to d r i l l two w i l d c a t wells.

EAOI farmed i n Block 226, f i l e d a Revised Plan of Exploration, and spudded the No. 1 w e l l on May 29, 1989. This w e l l was temporarily abandoned on July 9, 1989. However, t h i s w e l l had been tested on Ju-./ 7, 1989 and was determined to be capable of producing gas i n paying q u a n t i t i e s and was placed i n a minimum r o y a l t y status e f f e c t i v e w i t h the date of the t e s t , as stated i n your l e t t e r dated August 16, 1989.

Under t h i s I n i t i a l Development Operations Coordination Document (DOCD), EAOI proposes t o i n s t a l l a 3 - p i l e , 3-slot w e l l protector platform w i t h t e s t i n g f a c i l i t i e s and a h e l i p o r t over the e x i s t i n g surface of the No. 1 w e l l located at 4204' from the west l i n e and 4614' from the north l i n e of South Timbalier Block 226. A pip e l i n e w i l l be i n s t a l l e d and the lease w i l l be placed on production.

A c t i v i t i e s proposed under t h i s DOCD are expected to commence i n November, 1990, w i t h production commencing i n February, 1991.

A. Travel Modes and Frequency

EAOI w i l l operate out c f i t s onshore service base f a c i l i t i e s at Fourchon, Louisiana. During production operations a helicopter w i l l make two t r i p s per week, supply boats three t r i p s per week and crew boats w i l l make one t r i p per week. Transportation vessels w i l l use the most d i r e c t route t o the lease s i t e which i s located approximately 50 miles from Fourchon, Louisiana.

B. Support Base

The proposed a c t i v i t i e s w i l l u t i l i z e a support base at Fourchon, Louisiana. The base provides 24-hour service, a radio tower with phone patch, dock space, o f f i c e space, a parking l o t , eguipment and supply storage space, d r i n k i n g and d r i l l water, etc. These proposed production a c t i v i t i e s w i l l help to maintain t h i s base at i t s present l e v e l of a c t i v i t y . No expansion of the physical f a c i l i t i e s or the c r e a t i o n of new jobs i's expected to r e s u l t from the work planned i n conjunction w i t h Block 226.

C. New Support F a c i l i t i e s

No new onshore support f a c i l i t i e s such as new land bases, r e f i n e r i e s , storage f a c i l i t i e s , pumping s t a t i o n , boat docks, hel i c o p t e r pads or f u e l i n g f a c i l i t i e s are l i k e l y t o be reguired because of the a c t i v i t i e s planned f o r South Timbalier 226.

D. New Techniques or Unusual Techncloqy

No new techniques or unusual technology w i l l be required f o r t h i s operation.

E. Map of Proposed A c t i v i t y

As shown by the attached v i c i n i t y p l a t , the leases on which the proposed a c t i v i t i e s w i l l take place are located <*pp- oximately 50 miles form the Louisiana shoreline.

F. Coastal Zone Management Consistency

This p r o j e c t i s consistent w i t h Louisiana's program f o r Coastal Zone Management as provided i n 15 CFR 930 and the Louisiana State and Local Coastal Resources Management Act of 1978 (Act 361). The operations w i l l take place on the OCS outside of Louisiana's 3-mile l i m i t . Coastal e f f e c t s of the base are minor and are consistent with the Coastal Resources Program.

I I I . DESCRIPTION OF AFFECTED ENVIRONMENT AND IMPACTS

A. Physical and Environmental

1. Commercial Fishing

South Timbalier Block 226 i s located 50 miles from the Louisiana Coast i n the Central Gulf of Mexico where water ranges from 187' to 190' below main sea l e v e l .

The Gulf of Mexico y i e l d e d the nations l a r g e s t regional commercial f i s h e r y by weight i n 1988. The Gulf shrimp f i s h e r y i s the most valuable i n the United States accounting f o r 80% of the t o t a l domestic production. Three species of shrimp, brown, white

and pink dominate the J . ings. harvest of oysters anc takes place i n the Gulf -»a f i , and estuaries.

Menhaden i s the most valuable f i s h landed. Other im comercial f i s h include red snapper, spotted sea t r o u t , drum, shark, black n u l l e t t and sword f i s h .

The proposed operations i n t h i s area can be expected t o the commercial f i s h i n g i n the f o l l o w i n g ways:

Production platforms cause underwater o b s t r u c t i c r e s u l t i n losses of shrimp t r a w l s , shrimp cat vessel damage.

O i l s: t i l s pose the greatest t h r e a t t o coir f i s h " by d i r e c t contact w i t h eggc, larvae, j u o ss.- *d spawning adult f i s h or s h e l l f : cc .animation of estuary h a b i t a t .

Petroleum platforms i n the northern Gulf of Mexico (and other locations) c o n s t i t u t e unusual environments compared surrounding waters and s o f t bottoms i n t o which they ar embedded. Platforms act as n u c l e i f o r commercial ant fisherman and many species of f i s h l i n g e r near p-i n c l u d i n g those without trophic der ->ndenca upon them, species are found only around petroleum platforms and reefs i n the northern Gulf and include several groupers ar f i s h of economic value. For species such as these, avail of n a t u r a l habitat may be a l i m i t i n g f a c t o r , w i t h art reefs allowing f o r population expansion and a larger f i s h t

Typical species caught at the platforms include resident w e l l as those pelagic forms temporarily a t t r a c t e d t o them

Ov e r a l l , fishermen have ^ n e f i t e d from the growth petroleum industry i n the 3 waters of the Gulf of While technological improvements have enabled cot fishermen t o increase the volume of landings,, by-products developraent of the petroleum i n d u s t r y have also had a impact on f i s h i n g . Because OCS petroleum developt dependent on extensive marine -esse! u t i l i z a t i o n , hark ports have been improved, p o r t access waterways ha expanded and improved, and the a v a i l a b i l i t y and q u a l i t y o vessel maintenance and repair f a c i l i t i e s , have i s i g n i f i c a n t l y . These improvements have d e f i n i t e l y ha^ a e f f e c t on fishermen (LASSITER, 1980).

2. Shipping

South Timbalier 226 is clear of a l l fairways and anchorage areas. Operations in this area w i l l be in accordance with the U. S. Coast Guard's regulations regarding navigational standards. The i n s t a l l a t i o n and use of navigational aids, lifesaving equipment, and other safef. requirements pursuant to U. S. Coast Guard regulations are standard operating procedure for d r i l l i n g r i gs, platform and marine vessels u t i l i z e d by EAOI. There should be l i t t l e or no impact on shipping resulting from the proposed operations.

3. Recreational Resource and Acti v i t i e s

The northern Gulf of Mexico coastal zone is one of the major recreational regions of the United States, particularly with marine fishing, scuba diving, and beach-related a c t i v i t i e s . I t is estimated that over 38 m i l l i o n residents of the Gulf coastal states have a major interest i n water-related and water enhanced recieational a c t i v i t y . Approximately two-thirds of the Gulf shorefront i s composed of beach and there i s one motor boat for about every 21 people l i v i n g in the Gulf Region. More s p e c f i c a l l y , approximately 13.5 million people, or 35 percent of the Gulf States population, l i v e i n the area most d i r e c f y affected by Gulf a c t i v i t y , and about one-third of the registered boats are l i k e l y candidates for marine recreational a c t i v i t y (16' or greater).

I t i s reasonable to expect that production on blocks leased i n the Central Gulf of Mexico w i l l result in some ocean l i t t e r and could lead to one major o i l s p i l l , and that s p i l l and debris could be carried by wind, wave and currents to interact with major shorefront recreational beaches throughout the Gulf of Mexico. The trash and debris, such as o i l drums, large plastic containers and sheeting, computer read-write rings, seismic markers, styrofoam floats, pipe th. ead protectors, diesel f i l t e r s , hard hats and tar balls, i s c:^arly associated with the petroleum industry; however, the problem w i l l cause only localized, short-term inconvenience.

4. Cultural Resources

There are no known archaeological sites i d e n t i f i e d i n the area; however, EAOI agrees that i f any s i t e , structure or object of h i s t o r i c a l significance should be discovered during operations, the findings w i l l be immediately reported to the Supervisor and every reasonable ef f o r t w i l l be made to preserve and protect the cultural resources from danger u n t i l the Supervisor has given directions as to i t s preservation.

5. Ecologically Sensitive Features

There are no ecologically sensitive features i n the proposed area of operations.

"'here are no known pipelines t r a v e r s i n g Block 226

7. Other Mineral Uses

The a c t i v i t i e s proposed w i l l have no d i r e c t or i n d i r e c t impact on othe*- mineral uses.

8. Ocean Dumping

A l l produced waters w i l l be treated according t o OSHA regulations. Vessels w i l l be properly designated so that output w i l l meet a l l regulatory reguirements and w i l l not exceed 35 p a r t s / m i l l i c n . The produced waters w i l l be dumped overboard and monitored on a monthly basis.

9. Endangered or Threatened Species

Six f e d e r a l l y l i s t e d endangered whale species may occur i n the Gulf of Mexico: the blue f i n , humpback, r i g h t , sei and great sperm whales. The r i g h t whales are the most endangered cetacean i n the Gulf of Mexico.

The Fish and W i l d l i f e Servic has designated 15 untreated species that could be affected by OCS o i l and gas operations i n the Gulf of Mexico.

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 espouse time and effectiveness of the o i l s p i l l cleanup and containment services. Given these variables, the impact on the various endangered or threatened species w i l l vary frorr. l i t t l e or no e f f e c t t o very serious.

A large o i l s p i l l at South Timbalier Block 226 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 , selective and fu n c t i o n a l impairment of plankton communities, thereby a l t e r i n g .he COi.-.nuiiity s t r u c t u r e f o r an unknown period of time.

Air emissions from combustion of diesel f u e l i n engines and helicopters can a f f e c t the a i r q 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 clime':lr conditions.

Catastrophic events such as o i l s p i l l s and blowouts have the p o t e n t i a l t c reate l o c a l i z e d 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 to occur and i s not expected due to the low number of expected s p i l l s , probable distance from shore (m«-.re than 3 miles and very l i k e l y f a t h e r ) , r a p i d dispersion or breakup associated with o i l s p - l i s and the turbulent v a r i a b l e winds offshore. Rapid dispersion of evaporative emissions from these sources i s expected.

I f a blowout resulted i n a f i r e , s ubstantial l e v e l s of THC, N0„ S0„ CO and TSP would be emitted. Local a i r would be severely degraded f o r the duration of the - i r e . The extent of degradation i s indeterminate, but i t i s u n l i k e l y that i t would be high enough to a f f e c t land resources or human health.
