On Saturday, Aug. 28, a tanker truck rolled over at the intersection of Pickett Road and Route 236. The accident resulted in the release of 4,688 gallons of gasoline. The MCA was informed late Tuesday, Aug. 31, by Fairfax County that the environmental contractor recovered 2,569 gallons of liquid product by vacuum truck and an additional 1,441 gallons through the use of absorbent pads and booms. Approximately 200 gallons were also recovered by absorbent materials deployed by fire department personnel during the incident.
The following e-mail was sent by remediation specialist Randy Chapman of the Virginia Department of Environmental Quality to the MCA and local officials the evening of Aug. 31:
Today, personnel from our office walked up Crooks Branch to Prince William Drive. Petroleum odor was present in several areas and the stream appeared cloudy, but they did not observe any other obvious signs of impact past the area of booms and pads. As I mentioned earlier, until we have a change in weather, the odor will persist. In addition to the stream sampling, we have verbally (and through email) directed BTL (Baltimore Tank Lines) and their contractor to:
- Monitor and collect free product daily until Sunday, September 5. This will mainly include recovering free product at the Prince William Drive recovery point.
- Maintain awareness of the weather forecast for the Thursday-Friday time frame. If significant rainfall is expected, they are to consider removing the booms from Crook Branch (so we don't lose them down stream).
* Begin soil excavation at Main Street & Pickett Road (site of accident) on Thursday, September 2.
We will follow-up with a written directive (on letterhead) to BTL.
After September 5, we plan on discussing if additional daily monitoring is necessary or if monitoring can be scaled back to 2-3 times a week for the next couple of weeks (again, it's a dynamic situation and things may change).
If you have questions, please let me know.
