Problems/Comments
On August 18, 2014 a semi-truck and trailer rear-ended a tour bus that was stopped at a railroad crossing at milepost 169 Parks Highway (Alaska Railroad Corporation milepost 279.6). The impact caused a release of approximately 200 gallons of diesel fuel from the fuel tanks of the semi-truck to soil on the shoulder of the north bound lane. Fuel also impacted an adjacent unnamed drainage and migrated approximately 600 feet downstream from the spill site and into an area identified as wetlands by the Army Corps of Engineers. Initial response actions included removal of several thousand gallons of petroleum-contaminated water dammed by a boom in the drainage ditch and 102 tons of petroleum-contaminated soil. Excavation activities were limited due to integrity of railroad infrastructure. Confirmation sampling indicated diesel range organics remained in soil above DEC cleanup levels.
