Division of Waste Management and Radiation Control Comments ATK – Promontory Sampling Results Report and Proposed Corrective Action for SWMU #553 Figure 1 SWMU #553 Soil Sample Results
The results of the TCLP sample that are shown in the figure are reported in units of ppb. Please revise the figure to show the results in units of mg/L so it is clear that they are TCLP results. Section 4.0 Proposed Corrective Action
The proposal to dilute contaminated soil excavated from the SWMU #553 site with clean soil until concentrations of hexavalent chromium do not exceed Regional Screening Levels for residential soil is not an acceptable method under RCRA. The Division recommends that ATK send the excavated soil off-site to
a permitted, lined solid waste landfill for disposal. Section 4.2 Confirmation Sampling and Analysis Please change the reference to the RFI Work Plan QAPP to the more recent March, 2017 QAPP in this
section and Sections 4.6 and 5.0. Section 4.3 Decontamination Procedures
It is stated in this section that wastewater generated during field decontamination will be collected and disposed of properly. Please describe how wastewater will be properly disposed of.
