Information from TCEQ on West Incident
TCEQ staff members are involved in two aspects of this disaster.
1) TCEQ first arrived on-site at 9:37 p.m., Wednesday evening. The TCEQ Mobile Command Post arrived at 4:00 a.m., Thursday morning and is located a ½ mile from the blast site in West. It was up and running at 5:00 a.m. We are working under the incident command and are the lead for coordinating state assets to conduct air monitoring, plume modeling, and assessing all environmental concerns. Environmental assessments are underway.
2) To address immediate safety concerns, 12 Area RAE monitors have been set up around perimeter to monitor the air at distances ranging from a half-mile to a quarter-mile. At first light an entry team of TCEQ Emergency Response Contractors, 6th Civil Support Team, and EPA Contractors began to characterize the site to determine current facility emissions within the exclusion zone. TCEQ is actively monitoring air quality to assess any immediate health effects or threats.
At TCEQ headquarters in Austin, staff have compiled information about the company’s permits and compliance history.
AIR PERMIT AUTHORIZATIONS:
There are two air permit authorizations:
a. Permit #79803 for two 12,000-gallon anhydrous ammonia storage tanks; and
b. Permit #80404 for the material loading and storage operations of dry fertilizer materials.
The first air permit was issued on December 12, 2006 after technical review and with no comments received following an opportunity for public comment and contested case hearing.
The second permit was issued on March 15, 2007 after technical review and with no comments received following an opportunity for public comment and contested case hearing.
West Fertilizer Co. was originally constructed in 1962 prior to state and federal requirements to obtain authorization for emission of air contaminants. As a result, this facility was ‘grandfathered’ until state law required grandfathered facilities to obtain authorization, in this instance, September 1, 2004. Following a 2006 citizen complaint, the TCEQ investigated and issued a notice of violation.
In addition, to all appropriate rules and regulations of the agency, the facility operates under general and special permit conditions and other technical requirements.
More specifically, the applications were reviewed for protectiveness to ensure that emissions from normal, day to day operations would not have impacts off property. For the anhydrous ammonia application this included air dispersion screen modeling as well as special conditions in the permit to mitigate potential releases of ammonia. While this permit contains requirements that reduce the risk of an ammonia release, the TCEQ does not authorize upsets or emission events.
This facility has been subject to routine oversight and complaint driven investigations:
a. Investigation No. 10077 (Incident No. 6055): Dust complaint investigation conducted September 18, 2002 to October 3, 2002 – no nuisance conditions noted.
