On August 10, 2010 the National Response Center (NRC) notified EPA Region 6 of a 5000 gallon spill of an asphaltic material from a tank truck operated by Castus Transport into a creek at the Santa Fe National Forest in Sandoval Co., NM. EPA contacted the U.S. Forest Service (USFS) in Santa Fe, who reported the incident to the NRC, to get an update and gather more information about the incident. The USFS corroborated the volume (about 120 bbls) and indicated that the material was not solidifying and going into the creek. The creek is heavily flowing due to recent rains. Also, information was not clear as to the reponse capabilities of the RP and the USFS requested EPA assistance with the response. Based on further information, it appeared that the RP was not fully capable to respond to the incident. EPA activated the START-3 and deployed OSC Enders to the site.
