THE BOARD UNDERSTANDS THAT THESE MAPS INDICATE, AMONG OTHER ITEMS, THE FOLLOWING INFORMATION: THE RESPECTIVE OPERATORS OF, AND PRODUCTS CARRIED BY, THE PIPELINE SYSTEMS; THE DEPT. OF INTERIOR SEGMENT AND SEQUENCE NUMBERS; AND THE LOCATIONS OF RISERS, CROSSING PIPELINES, SUB-SEA TIE-INS, AND BLOCK BOUNDARIES. THE BOARD IS ALSO AWARE THAT RSPA IS ADDING THIS INFORMATION TO ITS NATIONAL PIPELINE MAPPING SYSTEM, WHICH IS BEING DEVELOPED IN COOPERATION WITH FEDERAL AND STATE AGENCIES AND THE PIPELINE INDUSTRY. ACCORDINGLY, P-90-4 HAS BEEN CLASSIFIED "CLOSED--ACCEPTABLE ACTION." Addressee Acronym: DOT Addressee Organization Type: G-Federal Government Communication Date: 1990-05-30 Communication Type: Official Correspondence Communication Contents: THE ATTACHMENT TO THIS RECOMMENDATION IS A TWO-VOLUME REPORT ENTITLED "AN ANALYSIS OF OUTER CONTINENTAL SHELF IMPACTS PIPELINES, NAVIAGATION CHANNELS, AND FACILITIES IN SENSTIVE COASTAL HABITATS." THIS STUDY WAS CONDUCTED AS PART OF THE MINERALS MANAGMENT SERVICE'S (MMS) ONGOING ENVIRONMENTAL STUDIES PROGRAM. THE MAJOR OBJECTIVE OF THIS STUDY WAS TO PROVIDE A BASIS FOR THE ASSESSMENT OF THE SIGNIFICANCE AND EXTENT OF PAST IMPACTS OF OUTER CONTINENTAL SHELF (OCS) RELATED ACTIVITIES ON SENSITIVE COASTAL HABITATS. THE MMS HAS A COMPLETE FILE ON EACH OF THE PIPELINES THAT IT HAS AUTHORIZED EITHER UNDER AN OCS OIL GAS LEASE, A RIGHT-OF USE AND EASEMENT, OR A RIGHT-OF-WAY. THAT FILE CONSISTS OF MAP, RECORDS, AND A DATA BASE. EVERY APPROVED OCS PIPELINE HAS BEEN PLOTTED ON MAPS MAINTAINED IN THE REGIONAL DIRECTOR'S OFFICE FOR MMS'S GULF OF MEXICO OCS REGION. THOSE RECORDS INCLUDE INFORMATION SUCH AS THE OWNER/OPERATOR, ORIGINATING AND ENDING POINTS, SIZE, PRODUCE TRANSPORTED, REPORTED BURIAL DEPTH, LENGTH, APPROVAL DATE, CONSTRUCTION DATE, MODIFICATIONS, REPAIRS, AND OTHER PIPELINES CROSSED.

OF INTERIOR (DOI) ASSIGNED PIPELINE SEGMENT NUMBER AND SEQUENCE NUMBER, LATITUDE, LONGITUDE, POINT DESCRIPTION CODE AND LOCATIONS OF RISERS, CROSSING PIPELINES, SUB-SEA TIE-INS, AND BLOCK BOUNDARIES. THIS INFORMATION WILL BE ADDED TO THE INFORMATION IN RSPA'S NATIONAL PIPELINE MAPPING SYSTEM, A NATIONWIDE MAPPING SYSTEM BEING DEVELOPED IN COOPERATION WITH FEDERAL AND STATE AGENCIES AND THE PIPELINE INDUSTRY.
