Title: Nonradioactive air emissions notice of construction for removal of 340A building tank solids

Technical Report ·
DOI:https://doi.org/10.2172/16870· OSTI ID:16870

The 340 Complex is a less-than-90-day storage unit for mixed waste generated on the Hanford Site. The 340 Complex receives liquid waste from various buildings in the 300 Area via underground transfer lines, or by containers from generators supporting Hanford Site programs. The tanks used for waste storage at the 340 Complex include two 57 kiloliter tanks within the 340 Underground Storage Vault and six 30 kiloliter tanks within the 340A building. The two underground vault tanks provide primary waste storage while the six tanks in the 340A building provide reserve storage capacity. The 340A Building tanks are not equipped with agitation devices and/or equipment. Consequently, past usage of the tanks has resulted in the formation, deposition, and settling of waste water solids. The deposited tank solids contain radioactive material that represent a source of radiation exposure to workers. For as low as reasonably achievable (ALARA) purposes, the solids must be removed periodically from the tanks. The most recent tank solids removal effort occurred in the early 1980s. The removal of solids from the 340A building tanks constitutes a modification, in accordance with WAC 173-460-020(14), and, in accordance with WAC 173-460-040, the proposed activities are subject to New Source Review. In accordance with WAC 173-460 and WAC 173-400, this document serves as a Notice of Construction (NOC) for periodically removing solids from the 340A Building tanks.
