SITE DESCRIPTION
On 1 November 2009, the United States Environmental Protection Agency (EPA) Response and Prevention Branch was requested by the Texas Commission on Environmental Quality (TCEQ) to assist in the identification of an unknown liquid. The unknown liquid was located at the western edge of the PRP’s property at 812 East Kennedale Blvd., Kennedale, Tarrant County, Texas. The PRP indicated the liquid was not on-site upon closing of the facility on the night of 30 October 2009. After receiving several resident's complaints of a foul oder, the Kennedale Fire Department responded to the event at 2100 hours on 30 October 2009. Preliminary analysis by the City of Kennedale Fire Department, with a HAZMAT ID, indicated that the main constituents of the liquid were dimethylamine and chloroacetaldehyde.

ACTIONS TAKEN

Following notification by the TCEQ, EPA Duty Officer Karen McCormick mobilized EPA OSC John Martin and the EPA representatives (EPA START contractor) to the site. EPA representatives were tasked with site investigation, air monitoring and identification of the unknown liquid. At 1225 hours on 1 November 2009, EPA representatives arrived on site and met with TCEQ Emergency Responder Paul Gorman and City of Kennedale Fire Department Contact J.C. Travis. An unknown amount of liquid was observed to be pooled on the ground near the western fence line of the PRP property.

Air monitoring was conducted for volatile organic compounds, amines, ammonia, carbon monoxide, hydrogen cyanide, chlorine, acid gases, hydrides, hydrogen sulfide, odor, oxygen, and an explosive atmosphere. Air monitoring results did not exceed background levels. The pH of the unknown liquid was determined to be in the range of approximately 7-8 standard units. A HAPSITE Gas Chromatograph/Mass Spectrometer (GC/MS) was used to analyze the vapors from representative samples of the unknown liquid and impacted soils. Preliminary results of the HAPSITE analyses primarily indicated the presence of chlorinated methanes. A magnetometer was utilized to determine the possible presence of buried tanks or drums. No large subsurface normalities were detected. At 1800 hours EPA OSC John Martin released EPA representatives from the site.

FUTURE PLANS

The TCEQ will oversee environmental cleanup to ensure that state guidelines are achieved. The property owner has committed to hire an environmental contractor whom will take additional samples to be analyzed at a laboratory to assist in determining the appropriate course of remedial actions to be taken. EPA will coordinate with TCEQ and the City of Kennedale Fire Department if further actions are required.

KEY ISSUES
Due to the results of the air monitoring and Hapsite data coupled with onsite observations, it was determined that the spill location did not currently posed an immediate threat to the public.
