<br />CONSTRUCTION MANAGEMENT APPROVED CLAMPS AND R6 IMIN) STRANDED CABLE SHALL
<br />REUTILIZED. CLAMPS TO REMAIN IN PLACE UNTIL PIPELINE IS TIED IN,
<br />RETIREMENT PROCEDURE FOR EXISTING PIPE:
<br />1. GT&D UTILITY WORK PROCEDURE TD 950OP-16,'DEACIVATION AND/OR RETIREMENT OF
<br />UNDERGROUND GAS FACILN'IES," SHALL BE FOLLOWED.
<br />2. THE EXISTING PI PE SECTIONS$HAL L HAVE FREE LIQUIDS REMOVED AN D BE LOOK 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 SOUSE 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. ANECE OF PIPE AT LEAST 24' LONG SHALL BE
<br />REMOVED. INSTALL A 1" HIGH PRESSURE SAVE -A -VALVE IH 17491, MD22287) TO CHECK FOR
<br />PRODUCTAND PRESSURE PRIOR TO CUTTING INTO THE PIPELINE THE OPEN ENDS OF THE
<br />RETIRED PIPE SHALL BE SEALED BY THE MOST APPROPRIATE METHOD OUTLINED IN GT&D
<br />UTIUTY WORK PROCEDURE T.9500P46. 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 TD4014P-01.
