1. DESCRIPTION OF PROPOSED ACTION

Mark Producing, Ine. plena to conduct exploration activities on East Cameron Blook

301 (OCS-0 7664).

As proposed, the Plan of Exploration for Beat Cam ere n Bloek 301 consists of drilling

three (3) wells.

At this time, planned commencement date for Well "A" and all associated activities

in the bloc* will begin on a about May 1, 1986.

(a) TRAVEL MODES, ROUTES AND FREQUENCY

The proposed exploration activity for federal leases OCS-G 7664 will

require the use of a jack-up rig to drill the exploratory wells. The rig will be

moved to East Cameron Blook 301 from an unknown location in the Gulf of

Mexico.

In addition to the drilling rig, service boats will be used to transport

equipment, material, personnel and supplies to the drill sites. It is estimated

thst the crew boat and supply boat will make daily round trips to the rig from

support bases Iciated in Galveston, Texas. The proposed travel route for these

vesseb begins at Galveston, Texas, and will move to Blook 30i via the moat

direct route from Galveston, Texas.

Helicopter flights to East Cameron Block 301 will average 10.5 round

trips per weak and will originate from and return to Galveston, Texas. The

helicopters will normally take the moat direct route of travel between the two

points when air traffic and weather conditions permit.

<W SUPPORT BASE

The propoaed activities wtll utilize a support base -t Galveston, Texas.

The base provides 24-hour service, a radio tower with phone patch, dock space,

1

office space, • parking lot, equipment end supply storsge space, drinking end

drill water, etc Theae proposed exploration activities will help to maintain

this bass st its preaent levels of activity. No expansion of the physical

facilities or tha creation of new Jobs is expected to result from the work

planned in conjunction witli Block 301.

Cs) NEW SUPPORT FACILITIES

No new onshore support facilities such as new land bases, ro fineries,

storaga facilities, pumping stations, boat docks, helicopter pads or fueling

facilities ara likely to be required because of the activities planned for Block

301. Any newly discovered deposits of hydrocarbons should help to maintain

onshore facilities and activities at or near their present levels rather than

result in some typo of expansion.

(d) NEW TECHNIQUES OR UNUSUAL TECHNOLOGY

No new techniques or unusual technology will be required for this

operation.

(e) MAPS OP PROPOSED ACTIVITY

As shown by the attached Vicinity Plat, the proposed activity is 1 sated

107 statute miles south-southeast of Cameron, Louisiana.

(f) TRANSPORTATION OP OIL AND/OR QAS

If producible hydrocarbons are found they are likely to be transported to

shore through connections with the pipelines already in place near Block 301.

DESCRIPTION OP THE AFFECTED ENVIRONMENT

(a) PHYSICAL AND ENVIRONMENTAL

(U Commercial Fishing

Eaat Cameron Block 301 is located approximately 107 miles from

shore where the weter depth is approximately 180-200 feet. Shrimp and

n.enhaden are the primary fishing resources found in this area.

The placement of a drilling rig on this Block will remove a portion

of the seafloor and waters above from harvesting by commercial

fisheries. Additionally, the waters adjacent to the driU sites may

become temporarily turbid due to drilling operations. These operations

should have no significant impact on commercial fisheries.

(2) Shipping

The southwest corner of Bast Cameron Block 301 Lies near the

boundaries of a designated shipping safety fairway. It may be likely that

the marine vessels supporting this block's activities will utilise a portion

of the shipping fairway to gain access to the Galveston, Texas support

base. It to unlikely, however, that they will have a significant affect on

fairway traffic. The drilling vessel and each of the marine vessels will

be equipped with all U.S. Coaat Guard required navigational safety aids.

(3) Recreation

The proposed activities, which are primarily confined to East

Cameron Block 30* are located approximately 107 miles south of the

Louisiana coastline. Along the coastal waters of the Gulf of Mexico oif

Cameron Parish, Louisiana, are located coastal beaches and ports

supporting pleasure boating and sport fishing. To protect these

recreational resources, Mark Producing, Inc. will comply with OCS Order

No. 7 regarding pollution prevention and control, and las established an

Oil Spill Contingency Plan wlich was approved by the Minerals

Management Service There are no adverse impacts expected as a result

of the proposed activities.

14) Cultural Rooources

East Cameron Blook 301 lies outside the Cultural Raaource

Sensitivity Demarcation Una (USDI, 1979, Visual 1) and. therefore, falls

in an area where cultural resources axe not likely to be found. An

archeological survey was not required for East Cameron Bloek 301. Mark

Producing, Inc. agrees that if any site, structure, or object of historical

or archeological significance should ba discovered during operation', the

findings will Se nmediately reported to the Supervisor and every

reasonable effort will be made to preserve and protect the culture,

resource from damage until tha Supervisor haa jiven directions as to its

preservation.

(5) Ecologically Sensitive Features

There are no known ecologically sensitive features located on East

Cameron Bloek 301. The closest sensitive feature is located along the

coastal shores of Cameron Parish, Louisiana. Tha sensitive features

include the primary fish and shellfish nursery grounds, and the

recreational beaches.

With exception to the minimal boat and helicopter traffic, all

operaUona will be restricted to Bast Cameron Blook 301. The proposed

activity will have no effect on any ecologically sensitive features.

(6) Existing Pipelines and Cables

A Stingray 16" gas pipeline (OCS-1 2122C) creases tne west line

approximately SS00 feet from tha northwest corner and crosses the south

Line approximately 5600 feet from the southwest corner.

(7) Other Mineral Uses

Tha activities propoaed for Eaat Cameron Blook 301 will have no

direct or indirect impact on other mineral uses.

(8) Oossn Dumping

Ocean dumping • prohibited in thii area.

(9) Endangered or Threatened Speciee

Mark Producing, Inc.'s proposed operations in Bast Cameron Block

SOI is located approximately 107 miles south of ths Louisiana coastUne

off Cameron Parish, Louisiana. Thsse coaatal shores anu upland areas

ars ths habitat of several endangered or threatened species. These

species Include the Arctic peregrine falcon, the rco-cockaded

woodpecker, the bald eagle, the American Alligator, tha red wolf,

Kemp's ridley sea turtle. Thsse species mey bs affected by the

development of coastal lands and/or tha occurrence of oil spills which

may affect ths species directly or through their food sources. Since ths

proposed activities include no plans for ths development of coastal lands,

ths impact on endangered or threatened species is primarily based on the

occurrence of oil spills.

On pages BJ-S through 111-72 of ths Pinal Environmental Impact

Statement for OCS Sale No. 47 thara is s discussion of ths factors for

estimating tha significance of oil spills and thair impacts. The impacts

on various endangered and threatened species will depend on ths nature

of the spill, weather conditions, proximity of spill to species, tolerance

for oil of species, and ths response time and effectiveness of the oil spill

cleanup snd containment services. Given these variables, the impact on

ths various endangered and threatened species will vary from little or no

sffsct to serious.

The experience of oil and gas exploration in the Gulf of Mexico

indicates that there is a small probability of occurrence of an oil spill.

Ths Draft Environmental Impact Statement (DEB) for OCS Sale No. A-

- 8 -

62 and 62 indicates on pogo 71 that tho "aggregrate 15 year spill rata to

.0009 percent of tha total volume produced." Table 7, page 73, of the

DEB indicated that there have Dean only 30 incidents of oil spills for this

15 year period. The probability remains low because of the level of

technology used by trie oil and gaa industry to insure safe and responsible

operations. Mark Producing, Ine. as a prudent operator will take the

necessary measures to reduce ths probability of oil spills. Mark

Producing, Ines proposed opsrstions in East Cameron Blook 301 should

pose no throat to any endangered or threatened species,

(b) SOCIO-ECONOMIC

(1) Related New Employment

Not applicable at this time.

3. UNAVOIDABLE ADVERSE IMPACTS

The proposed drilling activity in East Cameron Block 301 will result in the

discharge of drilling mud and cuttings into the waters of the Gulf. The discharge of

drill cuttings will bury sessile benthic organisms in local areas under the discharge.

Tha disposal of mud may result in a minor decrease in primary productivity die to

tha mortality cr functional impairment of phytoplankton and algaa in area of high

turbidity. A large oil spill is very unlikely but could result in localized severe

mortalities, and severe selective snd functional impairment of

phytoplankton communities, thereby altering the community structura for an

unknown period of time. These impacts are considered temporary and minor.

Air omissions from combustion of du el fusl in rig engines, boat engines and

helicopters can affect ths air quality near the mobile offshore Jackup drilling rig snd

near ths onshore travel router. In most cases, these emissions will be local in nature

snd will bs quickly cU.lp.fd by clim.tic condition.. Highly voUtlls, low molecular

- 6 -

weight hydrocarbons would bo released into tho atmosphere from a blowout with

release of natural gaa. Theaa hyl-ooarbona would undergo some unknown degree of

degradation, possibly resulting in photochemical smog. If a blowout resulted in a

fire, large amounts of particulate carbon and oxides of carbon, along with smaller

but unkown amounts of sulphur oxides, volatile hydrocarbons and partially oxidized

compounds would enter the air. Local air would ba severely degraded fcr the

duration of ths firs. Ths extent of degradation is indeterminate, but it is unlikely

that it would bs high enough to aff set land resources or human he cit h.

These explorstory activities are not expected to harmfully affect water

quality cr interfere with commercial fishing operations, recreational activities or

shipping traffic.
