1983 gas line explosion destroys Clear Lake apartment

CLEAR LAKE (KWWL) -- A natural gas leak led to an explosion and fire that destroyed an apartment building in Clear Lake on July 12, 1983.

Federal Documents show gas escaping under 60 psi from a crack in a 2-inch plastic gas main was to blame.

The explosion happened at 11:15 a.m. that day.  Two Interstate Power Company employees were hurt.  One apartment building was destroyed and an adjacent apartment building was heavily damaged.  Damage was estimated at more than $1 million.

The explosion led to the following recommendations for Plastic Pipe Institutes by the National Transportation Safety Board:

1. Urge its member companies to emphasize to users of plastic pipes the importance of explicitly following recommended fusion procedures.

2. Urge its member companies to cooperate with the Gas Research Institute in the development of nondestructive equipment testing capable of detecting inadequately fused butt, saddle, and socket fusion joints in the field.
