Narrative
On monday january 7, 2013 at 10:56, leak survey reported a type 1 gas reading of 10% in transmission main valve 43940 in front of 1119 longwood ave. Supervision and gas construction were dispatched. At 12:45 hrs gas construction reported that they performed a leak investigation and determined a probable leak was on transmission valve 43940. Gas control was notified and valve 46630 was identified to isolate the section of 36" transmission main. A code murre (multiple resource response event) was initiated and gas distribution services (gds) responded and located valve 46630 as contingency. At 14:02, gas control gave permission to gds to close valve 46630. Approximately 2,400 feet of 36", 303 psi main was affected and no reported system impact resulted from this section of main being isolated. An operational plan was developed and the segment of transmission main was reduced from 303 psi to approximately 60 psi through a pressure control temporary regulator connection to a 6" lppe distribution main at tiffany st. And oak point ave. On january 10, 2013 the valve was excavated and a visual leak was confirmed on the body bleed riser's welded connection at the bottom of the valve body. The valve manufacturer's representative was contacted and responded to the location to review repair options with engineering and gas operations' personnel. On january 14, 2013, the pressure was reduced further to low pressure and the leaking connection was cut, removed and a welded high hat installed. The high hat was tested and all tests passed. On january 16, 2013 a new riser was installed and restoration operations were initiated at 12:39. Leak survey monitored the segment as pressure was restored in 60 psi increments. At 19:56, the segment of isolated main was returned to normal operating pressure of 295 psi. The serious level ics structure was terminated at 20:18. Us DOT, nys psc, nyc dep and fdny were notified. The DOT-PHMSA office inquired about the leak. There were no reports of any injury, evacuation or media attention associated with this incident.
