PVC
6. Power reliability in accordance with 15A NCAC 02T .0305(h)(1):
❑ Standby power source or pump with automatic activation and telemetry - 15A NCAC 02T .0305(h)(1)(B)_
➢ Required for all pump stations with an average daily flow greater than or equal to 15,000 gallons per day
➢ Must be permanent to facility
Or if the pump station has an average daily flow less than 15,000 gallons per day:
• Portable power source with manual activation, quick -connection receptacle and telemetry - 15A NCAC 02T
.0305(h)(1)(C)
or
❑ Portable pumping unit with plugged emergency pump connection and telemetry - 15A NCAC 02T .0305(h)(1)(C):
➢ It shall be demonstrated to the Division that the portable source is owned or contracted by the applicant (draft agreement)
and is compatible with the station.
➢ If the portable power source or pump is dedicated to multiple pump stations, an evaluation of all the pump stations' storage
capacities and the rotation schedule of the portable power source or pump, including travel timeframes, shall be provided
in the case of a multiple station power outage.
