188.8.131.52 Facility Hazard Categories
Table 4-22 identifies the facilities at TA-46 that fall into a facility hazard category because of the
type of operations performed in the facility.
184.108.40.206.1 Nuclear Facility Hazard Categories
No buildings at TA-46 are categorized as nuclear facilities.
220.127.116.11.2 Non-Nuclear Facility Hazard Categories
18.104.22.168.2.1 Building Categorized M/CHEM
The Chlorine Storage Building (Building 340, Figure 4-24, Sheet 1), part of the Sanitary Wastewater
Treatment Facility, is the only building at TA-46 categorized M/CHEM.
The Sanitary Wastewater Treatment Facility is located in a canyon in TA-46. Because it is isolated
from other Laboratory facilities, it poses little to no hazard to personnel. The facility uses a chlorine
gas process (widely used in the public sector) to disinfect plant effluents before releasing them into
a holding pond. The process uses quantities of chlorine that exceed Occupational Safety and
Health Administration threshold quantities; no other facility at the Laboratory uses this amount of
chlorine. Although these quantities are significant, the process is a proven technology that incorporates
a state-of-the art, fail-safe process. The effluent-chlorinating system is equipped with influent
and effluent chlorinators, chlorinators for water to be recycled, standby chlorinators, cylinder-
mounted regulators, and stored cylinders of chlorine. The system contains various fail-safe
leak detectors, breathing apparatus, and chlorine cylinder emergency repair kits.
At the time that this document was being prepared, plans were being implemented to replace the
chlorine gas process with a new water disinfection process that does not use gaseous chlorine.
This change will eliminate the potential for accidental release of large quantities of chlorine.
22.214.171.124.2.2 Building Categorized L/CHEM

used for conducting large-scale photochemical experiments. The experiments performed
at this facility involve some hazardous operations and high-powered gas laser energy sources in
which toxic and/or corrosive gases are used. High-voltage hazards also are present. Small quantities
of high explosives have been used in this facility.

to handling tiny quantities of radioactive materials used for spectroscopic study of atoms
and molecules, applied photochemistry, and photophysics. Although Building 200 is the primary
location of these functions, several other buildings at TA-46 also accommodate some of these
