This abandoned irregular-shaped gravel pit was used for a highway-pavement asphalt-production project awarded in 1991. Blaze Construction was reported to have dumped petroleum waste oil & a powdered substance in the pit and also potentially buried 55 gallon drums of unknown substance at the pit and then covered it all. Geophysical Survey indicates numerous buried anomalies, which concurs with verbal reports. Reuse is slated for cattle grazing, greenspace use for local community members, &/or potential gravel pit being reopened for local use, upon buried hazards be removed.
Former Use: This abandoned gravel pit is located in the Baboquivari District of the Tohono O'odham Nation. Blaze Construction used the site in 1991 for asphalt production. In 1999 the US Attorney reached a plea agreement with Blaze Construction, who paid resitution to the Tohono O'odham Nation and the business was dissolved. The site is listed on the EDR database as a CERCLA site because of Preliminary Site Assessment Investigations. Ground Penetration Radar has been recommended to determine if there are buried drums at the site.
