2.1.1 Narrative
EPA was contacted by the NRC at approximately 1500 hours about a hazardous materials release due to a wreck on Interstates 40 and 440 in North Little Rock, Arkansas that occurred at approximately 1247 hours on 27 June 2011. EPA OSC and Weston Solutions, the Region 6 START contractor were dispatched to provide technical assistance and air monitoring at the site in support of the fire department and response contractor operations to mitigate the release.
START arrived on-scene at approximately 1910 hours on 27 June 2011. Twelve 300 gallon totes were in a ditch adjacent to the the interstate ramp. North Little Rock Fire Department Chief was IC and was providing decon and rescue support for B&P, the YRC response contractor. One Yellow Truck tractor and trailer had overturned on the ramp, releasing the totes through the roof and into the ditch. A grass fire was also associated with the wreck but was not at the site of the release.
START coordinated with the fire department and PRP contractors to provide air monitoring for phosphoric acid esters and general health and safety air monitoring. No hazardous constituents were detected in the air.
PRP response contractors began transferring the acid from the damaged totes into new totes after the truck and trailer were removed by a wrecker. Approximately 1000-1500 gallons were left in the damaged totes. ADEQ Emergency Response representatives had been at the scene earlier and had coordinated the operational plan and strategy with the involved parties. EPA OSC Adams coordinated with ADEQ and the on-scene fire department in support of the on-going response efforts. The highway ramp was reopened at approximately 2018 hours on 27 June 2011.
On 28 June 2011 PRP response contractors began removing contaminated soil and vegetation from the release site. It is estimated that approximately 120 cubic yards of soil and vegetation would be removed. No water was in the ditch and no water was affected by the release.
2.1.2 Response Actions to Date
Removal of damaged totes, non-released phosphoric acid and contaminated soil and vegetation from the release site. Air monitoring for hazardous constituents in the air at the site. Coordination between local, state and federal response organizations.
