HERMISTON - An update of the inspection schedule and other documents associated with incineration of chemical weapons at the Umatilla Chemical Depot slated to start in February 2003 was approved Thursday by the Department of Environmental Quality.
The approval allows the Umatilla Chemical Agent Disposal Facility to incorporate technical and administrative changes into the existing inspection schedule in the Hazardous Waste Treatment and Storage permit, according to a Notice of Decision sent out by the DEQ Thursday.
The permit modification request also proposed to reorganize the existing inspection tables into a series of smaller, more convenient tables.
The original inspection schedule was included as an attachment to the Hazardous Waste Permit. Based on operational experience from the Johnson Atoll Chemical Agent Disposal System in Alabama and the Tooele Chemical Agent Disposal Facility in Utah, and changing requirements in federal and Oregon hazardous waste regulations, the notice states that it was necessary for UMCDF to update the inspection schedule.
It also was determined, according to the notice, that the existing inspection schedule should be reformatted to make the document more user-friendly.
The revised document separates the inspection requirements into individual tables for storage inspections, treatment unit inspections, hazardous waste tank inspections, ventilation and agent monitoring inspections, support system inspections and safety and emergency equipment inspections.
Copies of this notice and response to comments made have been placed in both the Hermiston and Pendleton libraries, as well as the Portland State University Library, the Mid Columbia Library and the Hermiston DEQ office.
