5.4.2 NESHAP for Asbestos
There are numerous facilities, structures, components, and various pieces of equipment associated
with facilities at ORNL that contain asbestos-containing material (ACM). ORNL’s Asbestos Management
Program manages the compliance of work activities involving the removal and disposal of ACM and
current use of engineering controls and work practices, including inspections and monitoring for proper
removal and waste disposal activities of ACM, including notifications to TDEC for all demolition
activities and required renovation activities. No releases of reportable quantities of ACM occurred at
ORNL during CY 2009.
5.4.3 ORNL Radiological Airborne Effluent Monitoring
Radioactive airborne discharges at ORNL consist primarily of ventilation air from radioactively
contaminated or potentially contaminated areas, vents from tanks and processes, and ventilation for hot
cell operations and reactor facilities. (See Appendix F, Table F.1, for a list of radionuclides and associated
radioactive half-lives.) The airborne emissions are treated and then filtered with high-efficiency
particulate air filters and/or charcoal filters before discharge. Radiological airborne emissions from
ORNL consist of solid particulates, adsorbable gases (e.g., iodine), tritium, and nonadsorbable gases
(e.g., noble gases).
The major radiological emission point sources for ORNL consist of the following six stacks located in
Bethel and Melton Valleys (Fig. 5.12); the SNS Central Exhaust Facility stack located on Chestnut Ridge:
