i 2. Trajectory Analyses
Samedan O i l Corporation has i d e n t i f i e d the rones that appropriate and available t ra jectory analyses indicate may be impacted by an o i l s p i l l on Brazos Block A-37. As a source document for this analysis, we have used the Final Environmental Impact Study for Sales 118 and 122 (Book #98-0044J. Listed below are the results of the analysis:

Please refer to the Clean Gulf Associates Operations Manual Volume I I for a complete l i s t i n g of the envircrimentally sensitive resources and areas which could be affected by an o i l s p i l l i n this area. Listed are the map numbers in said manual which can be u t i l i z e d i n case of an o i l s p i l l to quickly identify specific biologically sensitive areas and resources:

I f an o i l s p i l l should occur on Brazos Block A-37, Samedan would do i t s best to respond in accordance with i t s Oil S p i l l Contingency Plan which was approved on August 18, 1987 by the Minerals Manaqement Service. Additionally, Samedan would do i t s best to notify appropriate agencies, identify biologically sensitive areas, and i n i t i a t e the appropriate response modes to quicxly and effectively reduce damage to property and the environment.
3. Response Base and Response Time
The primary response base for an o i l s p i l l in this area i s Port Aransas, Texas. The estimated response time for mobilize.tion, transportation and deployment onsite of the fast response skimmer system is 14 hours.
4. Clean Gulf Associates
As a member of the Clean Gulf Associates, Samedan has access to the various area of the Gulf of Mexico. An inventory of the available equipment along with response time i s attached.

B. Environmental Safeguards
(1) General
The goal of this Exploration Plan i s the gathering of more inforination on the geology of the lease area, i n a safe manner, with minimal disrupt ion of the environment. Various rules, regulations, codes, laws and practices have been developed over the years, which w i l l assist the operator to conduct operations i n th is manner. 30 CFR 250 Subpart C spec i f i ca l ly aeals with the environmental safeguards and safety of the d r i l l i n g and production operations. The regulations are s t r i c t l y adhered to by Samedan*
Environmental safeguards are b u i l t into the the operations i n several ways: i n the or ig ina l design of *.-'uipment and system of operations, i n the t ra in ing of personnel, i n th t preparation of procedures for operations and also in the procedures and ava i l ab i l i t y of equipnent for remed i a l actions in cases of emergencies.
Operations w i l l be conducted under the conditions described on the Application for Permit to Discharge on f i l e with the Minerals Management Service. Samedan conducts monthly tests to ensure that l iqu id wastes discharged into the Gulf of Mexico comply with E.P.A. Regulations.
(2) Environmental Safeguards i n the Design
The d r i l l i n g uni t is b u i l t to prevent pol lut ion of the Gulf of Mexico by u t i l i z i n g a system of curbs, gutters and surface drains which d i rec t a l l f l u i d s to a containment system. This system recovers hydrocarbons before water is discharged in to the Gulf of Mexico.
Liquid waste material, including sewage from the l i v i n g quarters w i l l be treated ir. a Minerals Management Service approved sewage plant on the d r i l l i n g un i t prior to discharge into the ocean. Solid waste materials are compacted and transported to shore for disposal.
D r i l l i n g operations are monitored by the Samedan representative on board. Mud and d r i l l cuttings w i l l be treated to remove o i l prior to discharge into the Gulf of Mexico. D r i l l i n g muc i s sampled and tested fo r t o x i c i t y according to EPA ICso standards. Items that cannot be treated properly w i l l be transported to shore fo r disposal.
{3) Training of Personnel and Procedures
Regular t ra in ing of operations personnel i s a necessary complement to the po l lu t ion prevention features i n the design of equipment and operat ions . Operator awarer:>*ss i s achieved by regular t ra in ing and enforcement of procedures. The d r i l l i n g uni t is inspected d a i l y . A procedure for the reporting of and dealing with o i l s p i l l s has been established by Samedan's i n accordance with the requirements of 30 CFR 250 Subpart C, which i s incorporated i n Samedan's "Oi l S p i l l Contingency Plan".

C. Safe ty Features
As i s the case w i t h the environmental safeguards, s a f e ty aspects must be a combination of des ign, opera to r awareness and the a v a i l a b i l i t y o f s u i t a b l e emergency equipment. Over the /ears, the O i l I ndus t ry and the Federal Government has issued a considerable number of standards, reconmended p rac t i ces and laws g o v ; r a n g minimum requirements . Oesign of equipment f o r Samedan's operat.. rti requi res the a p p l i c a t i o n of a l l a v a i l a b l e standards i n the s t r i c t e s - . manner. The most impor tan t o f these are l i s t e d below:
.•.OSHA
...OCS Orders of the Minerals Management Service
...API Standards and Recommended Practices
...ASME Codes
...ASTM Standards
...ANSI Standards
...AISC
...American Welding Society
...NFPA (NEC)
Safety systems are incorporated in the design of equipment and operational procedures as required by the OCS Orders of the Minerals Management Service. 30 CFR 2b0 Subpart D specifically provides detailed information on the d r i l l i n g operations and Samedan adheres s t r i c t l y to these rules and regulations.
Automatic gas and f i r e detection systems are incorporated in the unit to alarm operations personnel i n case of emergencies.

A, General
Samedan Oi l has f i l e d an application fo r a "Permit to Discharge" i n accordance with the requirements of the Environrrental Protection Agency.
B. D r i l l i n g Operations
Emissions discharged into the ocean w i l l be primari ly d r i l l i n g f l u i d , washed well cutt ings, cooling water and sewage e f f l u e n t . A l l these wastes w i l l be treated pr ior to discharge in to the sea to ensure a minimal impact or the environment. In cases where sat isfactory treat ing cannot be accomplished, wastes w i l l be collected and brought to shore for disposal. The following f igures show approximate quantit ies for wastes in this category:
. . . D r i l l Cuttings 650 tons per wel l
. . . D r i l l i n g Fluid 7,000 barrels per wel l
...Sanitary/Sewage Eff luent 4,000 gallons per day
. . .Cooling Water 1,000,000 gallons per day
Emissions discharged into the a i r during the d r i l l i n g phase w i l l be primarily associated with power generation. The fol lowing table l i s t s emissions during the d r i l l i n g operations (based upon Table 3.3.3-1 of EPA Publication AP-42):
