Narrative
A lightning strike on 09/01/2020 is suspected to have damaged a 12-inch valve assembly causing a leak which eventually ignited from an unknown source on 09/16/2020.

The resulting fire damaged aog's station infrastructure and resulted in an outage of three commercial customers in the immediate area. The station is in the process of being rebuilt and reconfigured to reduce the number of above ground appurtenances. Expected completion date is 11/13/2020.
