Narrative
On 1-17-11 the gas emergency response center (gerc) received a report of an outside gas odor complaint at w 135 st. And amsterdam ave. From the public. A gas distribution services (gds) crew was dispatched and upon investigating the complaint received 50% gas-in-air reading in the main valve box for v-3530 which is a 4" transmission pressure inlet valve that supplies regulator station gr-80. The main valve box was vented and the 50% reading dissipated. This valve is an elastoseal valve which could not be serviced and needed to be replaced. An operational plan was developed for the replacement of v-3530 and contingency plans were put in place to maintain supply to the manhattan high pressure system in the unlikely event the 30" transmission main, supplying the 4" inlet to gr-80, would have to be shutdown. The contingency plan called for the 59 st. Generating station as well as interruptible gas customers to cease gas usage. The area of the inlet piping to gr-80 was excavated and a control fitting and various fittings were welded, tapped and the 4" inlet main stopped-off successfully. The 4" main was depressurized and v-3530 was excavated and the valve and associated piping were cut and removed. The 5' replacement section (including new inlet valve) was successfully welded and x-rayed. Welded high-hats were installed and successfully mag-particle tested over various fittings. At 20:32 hrs 1-19-11, the transmission main was placed back in service. Regulator station gr-80 was placed back in service at 2000 hrs. This was a serious level incident.
