Bills Gas & Country Store

The Bill’s Gas and Country Store has been in operation for more than twenty years.

In March 1992, seven USTs along with two pump islands and all associated piping were removed from the site prior to the installation of a new UST system. Piping from an unknown third pump island was uncovered to the north of the two existing pump islands. The third abandoned pump island was completely covered with asphalt.
 
The original excavation extended to a depth of 15 feet below ground surface (bgs), as were the three pump island trenches. Confirmation samples were collected from the limits of the excavations. A number of the sample results were above Model Toxics Control Act (MTCA) Method A cleanup levels for total petroleum hydrocarbons (TPH) and for benzene, toluene, ethylbenzene, and xylenes (BTEX). Contamination was found beneath five of the USTs and the three pump islands. No additional excavation was conducted due to the proximity to site structures. No holes were discovered in the tanks when they were cleaned and inspected, thus the problem was deemed to be with the plumbing of the piping system, and to improper original installation. In total, over 250 truck loads were excavated and hauled away from the Chelan site. Following remediation, a restrictive covenant was recorded for the Site in 2003. 

Based upon cleanup activities and the recording of the restrictive covenant, Ecology has determined the site is no longer a threat to human health and the environment. Ecology issued a no further action determination in December 2003.

Periodic reviews are conducted every 5 years by Ecology for sites that have institutional controls. The review is intended to examine the effectiveness of cleanup activities and to assure the continued protection of human health and the environment.

Periodic review results

The property continues to operate as the retail petroleum facility. The majority of the site is covered by asphalt and building structures.  The restrictive covenant for the site was recorded and is in place. 

The cleanup actions completed at the site appear to be protective of human health and the environment.

Soil cleanup levels have not been met at the Site; however, the cleanup action is determined to comply with cleanup standards under WAC 173-340-740(6)(f), since the long-term integrity of the containment system is ensured and the requirements for containment technologies have been met.

The covenant for the property is in place and will be effective in protecting public health and the environment from exposure to hazardous substances and protecting the integrity of the cleanup action.

If the building is removed or replaced, contaminated soils beneath the site must be remediated.
 
No additional remedial actions are required by the property owner. It is the property owner’s responsibility to continue to inspect the site to assure that the integrity of the site surface is maintained.
