MOEPSl ls currently negotiating an agreement with Gulf, the offset lease holder, for Well No. 1.
MOEPSl's current r ig schedule cal ls for South Timbalier 260 No. 1 to commence dril l ing operations vith Odeco's Oceen Rover on February 10, 1985. I t l s anticipated that thc ve i l w i l l require 70 days to d r i l l and test. Water depth for the locations is approximately 305'.
The drilling operations wi l l bs supported from MOEPSl's base in Morgan City, Louisiana. No additional personnel or expansion of exleting fac i l i t i e s w i l l be required.
A comprehensive Oi l Sp i l l Contingency Plan has been previously submitted and approved by the Deputy Conservation Manager in accordance with OCS Order No. 7.

_ POLLUTION CONTROL MEASURES
I . Ecuipaept ••!.•.
A l l engines end puaps on the dr i l l ing rig ire equipped vith drip-pans or suaps. The collected liquids tre skinned; pollutants are stored in oil
• drums for disposal onshore, non-pollutants ire ducptd overhoird. i
The rotarj lable and drev-vorks hive i drip-pan to divert any o i l , grease • or other pollutants inco the sud systea.
O i l changes are to be performed under close supervision ar.d in such aanner is not to cau&e my pollutants to sp i l l overboard.
The dril l-cuttings may be ouaped overboard as they v i l l not pose any danger to carina l i f e unless o i l cud is used.
I I . Vests Disposal
A l l vastc material suitable for consumption by f i sh or other marine l i fe aay be discarded into tbe vater. Any coabustable vasts products sbould be incinerited, taking great cire not to endanger tbe r i g . All •non-edible, non—coabustable material is to be collected and transported to shore for disposal. The rig i s equipped vir'r. a burnt vests processing f a c i l i t y .

Tbe above directives apply nct only to the operation of the rig itself but also to a l l support vessels.
IV. Excess Dril l ing Mud
Any excess d r i l l i n g aud may be:
1. transferred tc another well , 2 . sold to a rel iable service company, or 3. pumped into f oral tions between tbe surface casing shoe and the
calculated top of cenient of the productior. casing, provided there ire not shews of bydrocarbons cr fresh vater 2cnes in that interval.
