filter effluent and meeting at a minimum 30,000 µWsec/cm2 after 10,000 hours of
operation, manufacturer recommended spare parts, piping, and controls; installation of an
autodialer alarm system to alert operator/owner of imminent UV failures so the necessary
actions are conducted to place the backup tablet chlorination/dechlorination systems in
service; in conformity with the project plans, specifications, and other supporting data
subsequently filed and approved by the Department of Environment and Natural
Resources.
This Authorization to Construct is issued in accordance with Part III, Paragraph A of NPDES
