WEST (April 21, 2013)—Investigators have located the epicenter of the massive explosion at West Fertilizer Co., and will be working inward from the areas of least to most damage, Assistant Texas Fire Marshal Kelly Kistner said Sunday,
Kistner declined to provide any details about the exact location of what he described as the “seat” of the blast, however.
He said a report will be produced on the investigation, but provide no timeline for the release.
A problem with a tank on the site caused several small fires Saturday, but no fires were burning at the scene Sunday, officials said.
The tank has been removed from the plant site, they said.
Union Pacific was in the process of repairing twisted railroad tracks Sunday.
Residents of one of the least-heavily-damaged areas evacuated after the blast were allowed to return home Saturday, but homes were without water, electrical or natural gas service.
A 7 p.m. curfew is in effect in the area.
Officials haven’t yet decided when residents of a second area between Walnut and Spring Streets will be allowed back in because Atmos is still testing natural gas lines, Mayor Pro-Tem Steve Vanek said Sunday.
The explosion Wednesday night killed 14, most of them first responders, and injured about 200, most of whom were treated and later released.
It damaged or destroyed dozens of homes and buildings including a nursing home, a two-story apartment complex and three of West’s four schools.
