Pipeline Segment-5232-WesJ_Cameron B10C1L-24Z Well No to a sub-sea t i e - i n i n -Block 2

On October 9, 1990, the subject pipeline parted a f t e r apparently being h i t with an anchor. The platform immediately shut i n on the PSL and on October 12, 1990 the pipeline parting was v e r i f i e d with divers.

On October 23, 1990, a repair crew with divers went to the location and over the next three days a 60' section of damaged l i n e was removed and replaced using Big Inch Marine connections at the ends of the new section of pipe. After repairing the l i n e , i t was reburied to 3' below the mud l i n e . The pipeline was tested on October 28, 1990 to 2190 psi and the pipeline placed back i n service. Attached are copies of the test chart and the deadweight gauge readings.

NEPA CATEGORICAL EXCLUSION REVIEW

The Categorical Exclusion Review (CER) evaluated the proposed action and determined that i t meets the categorical exclusion criteria as defined by 516 DM 2.3A(1) which states "(a) The action or group of actions would have no significant effect on the quality of the human environment, and (b) The action or group of actions would not involve unresolved conflicts concerning alternative uses of available resources." The analysis of potential impacts by environmental and resource specialists was based on the assumption that the following mitigative measure(s) will be Imposed.

Environmental Protective Measures

The following measure was Identified 1n the plan/application by the lessee/operator submitting the proposal: None.

The measure identified by MMS during the plan/application review or in the lease stipulation was:

Our analyses indicate that the following anomalies and/or side-scan sonar contacts are located within the seafloor disturbance area of the proposed activities. Should any of these anomalies and/or contacts represent a hazard to their activities, precautions as outlined in NTL No. 83-3, Section IV.B., will be taken prior to conducting operations.

Blocks Line No. Shot Point Remarks

Galveston 427 4 45.4

Exclusion Determination

44 gammas in intensity

The proposed action was evaluated and reviewed against the CER exception criteria defined by 516 DM 2.3.A(3). With inclusion of the above mitigation, i t does not represent an exception to the categorical exclusions. Therefore, preparation of an EA is not required.
