This is a local government owned and operated facility for the production of potable water for the City of Helena. The only reportable regulated substance for the RMP plan is chlorine. No more than two ton cylinders are on line at a time. The online tanks are on isolated regulators that reduce the chlorine pressure to a vacuum state. Chlorine feed equipment supplies a vacuum to the tanks allowing the release of chlorine to the feeders.
All feed lines supply chlorine below atmospheric pressure.
No flammable substances or other restricted items are stored in the chlorine tank rooms. The room has a chlorine detector connected to an alarm panel, annunciator horn, computer, and autodialer. All unacknowledged alarms initiate the autodialer which calls all on duty and off duty personnel till acknowledged. If the alarm conditions exists after an hour it again starts calling operators out. All alarms and autodialers are on uniterruptable power supplies, batteries and back up electrical generator.
