The steam and condensate system is no longer operable in Building 991. The function
has been replace by weatherproof boilers located outside Building 99 1, Room 166. The steam
and condensate lines were removed from inside Room 137 of Building 99 1 out to the northeast
comer of Building 99 1.
2.3.5.3 Sanitary Process Waste Systems
All sanitary drains leave the building at the east side and into a manhole located by the
northeast corner of Room 166. The basement tunnel floor drains are connected to a lift station at
the southeast corner of the basement and two pumps, each controlled by a float switch, discharge
into the sanitary drain line leaving the building. The Building 991 sewer line connects to the
main sewer line at a manhole northeast of Building 99 1 just inside the PA.
There are process waste tanks located outside the south wall of Building 991 by
Room 1 10 that are used to collect process waste from Room 1 10 and spray down water from the
hood exhaust ducts. The tanks have high level alarms and are normally operated by
metallography laboratory personnel. These process waste tanks are currently out of service and
no hazardous materials are generated in the metallography laboratory.
