PROPOSED TYPE AND SEQUENCE OF EXPLORATION ACTIVITIES AND TIMETABLE
Section 2
Huffco Petroleum Corporation proposes t< Supplemental Plan of Exploration to d r i l l three additional wells on South M^rsh Island Block 234 to further evaluate the subject lease to determine the potential for future development.
Exploratory d r i l l ng of the f i r s t well is scheduled tc commence approximately February 21, 1986, subject to the approval of this Plan of Exploration and issuance of the required Permit to D r i l l . Exploratory dr i l l i n g should be completed by July 6, 1986.
I t should be emphasized that this schedule is tentative in the meaning of 30 CFR 250.34-l(a). Additional exploratory d r i l l i n g must be predicated upon the need to define structures and/or reservoir limits. The fabrication and installation of platforms, producing f a c i l i t i e s and pipelines are contingent upon the success of the r wells. In addition to the dr i l l i n g of wells, other activities which may bt conducted under this plan would be the setting of caissons or a template over temporarily abandoned wells, a velocity survey in a wellbore and soil borings.

SAFETY AND ENVIRONMENTAL SAFEGUARDS
Section 4
Safety features during d r i l l i n g operations w i l l include well control and blowout prevention equipment that meets or exceeds the requirements of OCS Order No. 2.
011 in any form shall not be disposed of into the waters of the Gulf.
Liquid waste materials containing substances which may be harmful to aquatic l i f e or wildlife, or injurious in any manner to l i f e or property shall be treated to avoid disposal of harmful substances into the waters of the Gulf.
Drilling muds containing o i l are not disposed of int., the Gulf. This type of material 1s loaded and barged to shore for proper disposal. Drilling mud containing toxic substances is neutralized prior to disposal.
Drill cuttings, sand and solids containing o i l are not disposed of into the Gulf, unless the o i l has been removed.
The subject offshore mobile d r i l l i n g unit is equipped with drip pans under the rig floor. All o i l from diesel engines is pumped to a sump and then pumped into barrels for return to an onshore site.
Operator personnel are instructed in the techniques and methods necessary to pi event pollution. Non-operator personnel are instructed and supervised to insure that non-pollutlon practices are adhered to.
The facilities are inspected daily.
OIL SPILL CONTINGENCY PLAN
Huffco Petroleum Corporation's Oil Spill Contingency Plan has been approved by the Minerals Management Service. This plan designates an Oil Spill Team consisting of Huffco Petroleum Corporation personnel and contract personnel. This team s duties are to eliminate the sources of the o i l s p i l l , remove all sources of possible ignition, deploy the most viable means of available transportation to monitor the movement of the slick, and contain and remove the slick 1f possible.
Huffco Petroleum Corporation is a member of Clean Gulf Associates (CGA). The CGA has 4 permanent bases 1n Louisiana; at Venice, Grand Isle, Intracoastal City and Cameron, and two bases in Texas; at Galveston and Rockport. Each base is equipped with fast response skimmers and there is a barge mounted high volume open sea skimmer based at Grand Isle. In addition to providing equipment, the CGA also supplies advisors for clear, up operations.- Response time for a s p i l l in South Marsh Island Block 234 would be epproximately 4 hours depending upon the location of company operated workboats or workboats available for charter.
