1.0 PURPOSE
1.1 This alarm response procedure provides guidance to Nuclear Chemical Operators for
responding to alarms associated with graphic “Primary Exhaust Trains” (17 or graphic
#17) on the AY/AZ ventilation system Monitor and Control System (MCS), or the Tank
Farms Monitor and Control System (TFMCS).
1.2 Environmental Compliance
Tank farm ventilation systems and exhaust monitoring systems are regulated under
Washington Administrative Code (WAC) Chapters 173-400, 173-401, 173-460 and 246-
247 and applicable Notices of Construction (NOC) issued to ensure compliance with
these regulations. To ensure reporting requirements are met, all planned and unplanned
outages of tank farm ventilation and exhaust monitoring systems, including portable
exhausters, must be reported to the appropriate shift office for evaluation with
Environmental for possible notifications in compliance with TFC-ESHQ-ENV_FS-C-01.
2.0 OPERATION
2.1 OPERATE MCS in accordance with procedure TO-060-356.
2.2 RESET Object Error (OE) and Priority Command Interlock conditions or alarms not
identified in this ARP with procedure TO-060-350.
