A comprehensive o i l s p i l l contingency plan haa been submitted to the Minerals Management Service, Regional Superviaor, in accordance with OCS Ordar No. 7. Thia plan covera equipment, materials and procedurea for prompt response to o i l s p i l l s . In addition, detailed provieions for o i l s p i l l prevention are included in OCS Order No. 2, which includes procedures for dr i l l ing , setting casing, blowout prevention and mud control .

The baae of operationa w i l l take place at Dulac, Louiaiana. T h i s base ia 5 acres in extent and employs twelve (12) persons aa baee personnel. Approximately 2% of the ac t iv i ty at thia baae w i l l be appl ied to tha project . In addition, the o f f i ce of FMP Operating Ccmpany in Now Orleans w i l l allow approximately 1.0 person-years to the subject project . No new employees w i l l be added, and no new f a c i l i t i e e ara anticipated to move into the area.

PMP Operating Company ia a member of Clean Gulf Aaaociatea which maintains standby o i l a p i l l containment and cleanup equipment. Thie equipment includes skimmer systems for inshore and offshore waters, and auxil iary ahallow water and beach cleanup equipment. Peraonnel to operate the equipment are located in Dulac, Louiaiana. The faat response ayatitm and peraonnel could be on location in 10 to 12 houra.

The data reviewed i n c l u d e d : (1) on E-w l i n e 100 south of the l o c a t i o n from a hazard aurvey conducted by John Chanco and A s s o c i a t e s f o r Texaco in 1983, which c o n s i s t s of p inker (subbottom p r o f i l e r ) , s i d e - s c a n sonar, magnetometer, and s i n g l e - t o l d sharker data; however, a t t h i a time, Texaco has not been ab le to f i n d t h e i r sparker d a t a . An Archeologica l and Hazard Report of Block 190 by John Chance and Assoc ia te s for Texaco dated August, 1983, has a d e t a i l I n t e r p r e t a t i o n o f these data; (2 ) a N-S l i n e 150' e e s t of the l o c a t i o n from a survey conducted by Texan A&M f o r the USGS (now *IS) i n 1972, which c o n s i s t s o f subbottom p r o f i l e r and s i n g l e - f o l d sp rker data; (3) a N-S l i n e 900' west and on E-W l i n e IOOO' nor th of the l o c a t i o n from a survey conducted by ONI O f f s h o r e Engineer ing Surveys for the USGS i n 1975, which cons is t s o f subbottom p r o f i l e r , s i n g l e - f o l d s p a r k e r , s i d e - s c a n s o n a r , and magnetometer data; and (4) a NE-SW 2 4 - f o l d s e i s m i c l i n e a c r o s s the l o c a t i o n which was shot by Texaco l n 1981.
