The affected pipelines were designed and constructed by the government-owned CPC Corporation. However, CPC said that the pipeline system did not show any sign of problems before the explosion. The gas pipelines were approved in 1990 by Vice President Wu Den-yih, who served as mayor of Kaohsiung from 1990 to 1998, and the construction was completed in 1994. The pipelines had not been properly inspected for 24 years.
