Efforts at the scene of the April 27th gasoline tanker spill northwest of Lyons, have transitioned from the emergency phase to the project phase.  EPA, Colorado State Patrol, CDPHE, and Boulder County continue oversight of the work.  Lyons Fire Protection District continues to provide fire support.

Response contractors have completed excavation of the contaminated soils and begun backfilling the area.  Contaminated soils are being transferred off-site for disposal and this work is expected to continue through the end of next week.  Once the contaminated soils are removed, response contractors will begin restoration of the impacted properties.  EPA does not expect any road closures over the weekend due to site work.
