Narrative
On august 9, 2019 at approximately 14:28 hours consumers energy was notified of damage to a 6" steel medium pressure natural gas pipeline located near 3340 w. Tienken, rochester hills, michigan (oakland county). A consumers energy gas service worker (gsw) arrived at approximately 14:50 hours confirming damage to the pipeline and requested a distribution crew.

The distribution crew arrived onsite at approximately 16:57 hours. Mueller control fittings were installed to isolate the damage segment and a plidco bolted split sleeve fitting used as a temporary repair. A pumpkin was installed on august 22, 2019 to permanently repair the damaged segment.
