An Operations Plan for an Offsite or Portable Treatment Facility for the remediation of petroleum and chlorinated solvent-contaminated soil has been submitted to the Department of Environmental Conservation (DEC) for approval in accordance with 18 AAC 75. 365 and 18 AAC 78.273.  The plan details are as follows:

Applicant:                    Soil Treatment Technologies, LLC.
                                    8361 Petersburg Street
                                    Anchorage, AK 99507

Proposed Activity:       Soil Treatment Technologies, LLC proposes to receive and treat petroleum and chlorinated solvent-contaminated soils under a DEC approved Operations Plan. Contaminated soil is transported and stored in containment pending treatment by thermal desorption. Thermal desorption is a two-phase treatment, volatilizing contaminants in the soil then treating the vapors with thermal oxidation.  Following treatment, soils will be sampled to confirm that the DEC soil cleanup levels are met before the treated soils are released for reuse or disposal. The existing facility will be reconfigured to increase capacity of contaminated soil resulting in a larger footprint and increased wastewater treatment.    

Location:                     2301 Spar Avenue, Anchorage, Alaska
