<br />100 PSI AND AT OPERATING PRESSURE BEFORE COATING CAN OCCUR.
<br />10, PAINTING AND COATING REQUIREMENTS:
<br />A. ALL EXPOSED PIPE AND FITTINGS ARE TO BE PAINTED IN ACCORDANCE WITH GAS STANDARD
<br />E-30. ALL COATING ON BURIED PIPE AND FITTINGS ARE TO BE APPLIED IN ACCORDANCE WITH
<br />GAS STANDARD E-35.
<br />B. FOR COATING SELECTIONS ON BURIED PIPE, SEE DIRECT BURIAL COATING SELECTIONS TABLE.
<br />11. INSPECTION OF EXISTING PIPELINE:
<br />A. WHENEVER EXISTING BURIED GAS FACILITIES ARE EXCAVATED DURING ENGINEERING OR DURING
<br />CONSTRUCTION, FOLLOW TD-510OP-01 TO DOCUMENT PIPE INSPECTION. THIS APPLIES TO EXISTING
<br />AND TO BE RETIRED FACILITIES.
<br />B. EXISTING GIRTH WELDS, AT TIE-IN LOCATIONS, SHALL BE IDENTIFIED AND REMOVED IF PRACTICAL,
<br />C. PRIOR TO TIE-IN, INSPECT COATING AND PIPE FOR DEFECTS, IF DEFECTS ARE FOUND,
<br />CONTACT PED FOR GUIDANCE.
<br />12. TIE-IN AND CLEARANCE PROCEDURE TO BE PREPARED AND PERFORMED IN ACCORDANCE WITH
<br />THE FOLLOWING WORK PROCEDURES:
<br />A. TD -4100-01, HOT AND COLD WORK METHODS FOR NATURAL GAS TRANSMISSION PIPELINE
<br />SHUTDOWN AND TIE-IN.

<br />13. COATING REMOVAL:
<br />A. PERFORM THE FOLLOWING STEPS, IN ACCORDANCE WITH TD -4711P-01, BEFORE REMOVING
<br />ASPHALTIC PIPE WRAP ON PIPELINES INSTALLED PRIOR TO 1972 (BASED ON PG&E ANALYSIS,
<br />PIPE INSTALLED IN 1972 OR LATER DOES NOT HAVE PIPE WRAP THAT CONTAINS ASBESTOS):
<br />1. REFER TO THE "EXISTING PIPE SPECS (PRE -1972)" STAMP TO DETERMINE IF A SAMPLE HAS
<br />BEEN COLLECTED OR IF A SAMPLE IS REQUIRED:
<br />a. "YES" REPRESENTS HISTORICAL RESULTS ARE AVAILABLE SHOWING THAT PIPE WRAP
<br />CONTAINS ASBESTOS. NO SAMPLE IS REQUIRED.
<br />b. "NO" REPRESENTS HISTORICAL RESULTS ARE AVAILABLE AND THE PIPE WRAP DOES NOT
<br />CONTAIN ASBESTOS (CONTENT WAS NON DETECT). NO SAMPLE IS REQUIRED.
<br />c. "UNKNOWN" REPRESENTS NO HISTORICAL RESULTS ARE AVAILABLE. A SAMPLE IS
<br />REQUIRED IF THE PIPE INSTALLATION DATE IS PRIOR TO 1972.
<br />2. WHEN A PIPE WRAP SAMPLE IS REQUIRED TO BE ANALYZED FOR ASBESTOS:
<br />a. COLLECT SAMPLE PER TD -4711P-01 AND COMPLETE CHAIN OF CUSTODY FORM
<br />TD-4711P-01-FOl.
<br />b. FILE PINK COPY OF THE CHAIN OF CUSTODY FORM AND FINAL LABORATORY RESULTS
<br />WITH THE AS -BU I LTS.
<br />3. WHEN REMOVING PIPE WRAP THAT CONTAINS ASBESTOS, OR FOR EMERGENCY WORK,
<br />FOLLOW TD -4711P-01 "PIPE WRAP REMOVAL, HANDLING AND DISPOSAL".
<br />CATHODIC PROTECTION NOTES:
<br />1. FOLLOW TD-510OP-01 TO DOCUMENT INTERNAL CORROSION AND EXTERNAL CORROSION
<br />INSPECTION OFTHE PIPELINE.
<br />2. UPON COMPLETION OF BORINGS, CONTACT THE CORROSION SUPERVISOR FOR THE LOCAL
<br />AREA/DIVISION TO PERFORM CURRENT DRAIN TESTS ON THE PIPELINE SEGMENT THAT
<br />WAS INSTALLED IN THE BORE. THE CURRENT DRAIN TEST MUST BE PERFORMED PRIOR TO
<br />WELDING PIPE ON EITHER SIDE OF THE BORE.
<br />3. FOR THE INSTALLATION OF THE OMNIMETRIX RECTIFIER REMOTE MONITOR, CONTACT THE
<br />CORROSION SUPERVISOR FOR THE LOCAL AREA/DIVISION.
<br />4. BONDING CABLES TO BE INSTALLED ACROSS PIPELINE CUT-OUTS AT ALL LOCATIONS THE
<br />PIPELINE IS SEVERED PRIOR TO REMOVAL. CHAIN CLAMPS, MAGNETIC CLAMPS, OR OTHER
<br />CONSTRUCTION MANAGEMENT APPROVED CLAMPS AND N6 (MIN) STRANDED CABLE SHALL
<br />BE UTILIZED. CLAMPS TO REMAIN IN PLACE UNTIL PIPELINE IS TIED IN.
<br />RETIREMENT PROCEDURE FOR EXISTING PIPE:
<br />1, GT&D UTILITY WORK PROCEDURE TO 950OP-16, "DEACTIVATION AND/OR RETIREMENT OF
<br />UNDERGROUND GAS FACILITIES," SHALL BE FOLLOWED.
<br />2. THE EXISTING PIPE SECTIONS SHALL HAVE FREE LIQUIDS REMOVED AND BE 10096 PURGED
<br />PER GAS DESIGN STANDARD A-38, "PROCEDURES FOR PURGING GAS FACILITIES."
<br />3. THE PIPE SHALL BE SECTIONALIZED AT INTERVALS AS SPECIFIED IN THE RETIREMENT PLAN.
<br />THE LOCATIONS CALLED OUT ARE APPROXIMATE AND ARE SUBJECT TO FIELD VERIFICATION TO
<br />IDENTIFY THE MOST OPTIMUM LOCATION IN THAT VICINITY. ACCURATE SURVEY DATA MAY
<br />NOT BE AVAILABLE FOR THESE LOCATIONS SO USE CAUTION DURING EXCAVATION AND WHEN
<br />IDENTIFYING THE PIPELINE TO BE RETIRED. OTHER ACTIVE PIPELINES MAY BE IN THE AREA.
<br />4. AT EACH SUCH LOCATION NOTED ABOVE, A PIECE OF PIPE AT LEAST 24" LONG SHALL BE
<br />REMOVED. INSTALL 1" HIGH PRESSURE SAVE -A -VALVE (H-17491, M022287) TO CHECK FOR
<br />PRODUCT AND PRESSURE PRIOR TO CUTTING INTO THE PIPELINE. THE OPEN ENDS OFTHE
<br />RETIRED PIPE SHALL BE SEALED BY THE MOST APPROPRIATE METHOD OUTLINED IN GT&D
<br />UTILITY WORK PROCEDURE TD-950OP-16. BACKFILL MUST BE THOROUGHLY COMPACTED IN
<br />PLACE OF THE REMOVED SECTION OF PIPE.
<br />DESIGN CHANGE PROCEDURE
<br />MAINTENANCE AND CONSTRUCTION PERSONNEL MUST OBTAIN APPROVAL FROM THE PROJECT
<br />ENGINEER (PED) BEFORE MAKING ANY DESIGN CHANGE TO GAS FACILITIES PER TD -4014P-01.
