DEPARTMENT OF THE INTERIOR
Minerals Management Service
 
Preparation of an Environmental Assessment for Kerr-McGee's 
Proposed Deepwater Development Plan Offshore Texas (Boomvang Project)

AGENCY: Minerals Management Service, Interior.
ACTION: Preparation of an environmental assessment.

-----------------------------------------------------------------------

SUMMARY: The Minerals Management Service (MMS) is preparing an 
environmental assessment (EA) for a proposed deepwater development plan 
to develop and produce hydrocarbon reserves about 114 miles offshore 
Texas in East Breaks, Blocks 642, 643, and 688.

FOR FURTHER INFORMATION CONTACT: Minerals Management Service, Gulf of 
Mexico OCS Region, 1201 Elmwood Park Boulevard, New Orleans, Louisiana 
70123-2394, Mr. Alvin Jones, telephone (504) 736-1713.

SUPPLEMENTARY INFORMATION: This EA implements the tiering process 
outlined in 40 CFR 1502.20, which encourages agencies to tier 
environmental documents, eliminating repetitive discussions of the same 
issue. By use of reference to the most recent Final Environmental 
Impact Statement (EIS) for the Gulf of Mexico Western Planning Area for 
Lease Sales 171, 174, 177, and 180 and by tiering to related 
environmental documents, this EA concentrates on environmental issues 
specific to the proposed action.
    The MMS Gulf of Mexico Region received an Initial Development 
Operations Coordination Document (DOCD) from Kerr-McGee Oil and Gas 
Corporation (Kerr-McGee) that proposes to develop and produce 
hydrocarbon reserves located in East Breaks, Blocks 642, 643, and 688. 
The DOCD was assigned a plan control number of N-7077, and the project 
is referred to as the Boomvang Project. Kerr-McGee will complete and 
produce a total of 10 wells that were drilled under previously-approved 
Exploration Plans for the subject blocks. No new drilling operations 
are proposed as a part of this DOCD. All of the wells will share a 
common surface location (a truss spar floating production system) in 
East Breaks, Block 643.
    The Boomvang truss spar is a manned floating production facility 
that will be permanently anchored on location by a 9-leg, taut catenary 
system composed of conventional wire, chain, and anchor piles. The hull 
portion of the spar

[[Page 23727]]

measures approximately 90 feet in diameter and has an overall length of 
543 feet. No hydrocarbons will be stored in the hull of the spar. The 
spar is not drilling rig capable; however, a 1,000-hp completion/
workover platform rig will be installed and used for the initial 
completion operations. If any additional drilling would be necessary, a 
mobile offshore drilling unit (MODU) would be utilized. The spar will 
have a 20-person permanent accommodation unit installed. Temporary, 
portable quarters for up to 48 people may be provided.
    The water depth at the truss spar location is approximately 3,457 
feet. The project will use an existing onshore support base in Sabine 
Pass, Texas, to support the production activities. During completion or 
workover operations, either the onshore base in Sabine Pass, Texas, or 
an existing onshore base in Galveston, Texas, will be used to support 
these activities.
    Oil and gas produced at the Boomvang project will be transported 
off lease by third-party owned and operated right-of-way pipelines.
    The proposed action analyzed in the EA will be the development plan 
as proposed by Kerr-McGee. Alternatives will include the proposed 
action with additional mitigations and no action (i.e., disapproval of 
the plan). The analyses in the EA will examine the potential 
environmental effects of the proposal and alternatives.

Public Comments

    MMS requests interested parties to submit comments regarding issues 
that should be addressed in the EA to Minerals Management Service, Gulf 
of Mexico OCS Region, Office of Leasing and Environment, Attention: 
Regional Supervisor (MS 5410), 1201 Elmwood Park Boulevard, New 
Orleans, Louisiana 70123-2394. Comments must be submitted no later than 
30 days from the publication of this Notice.
