This authorization results in no increase in design or permitted capacity and is awarded
for the construction of the following specific modifications:
Installation of an effluent v-notch flow meter and recorder, and a 7,500-gallon

piping, and a 35 CFM blower, including piping, valves, vaults, electrical, controls,
and other appurtenances necessary to provide a complete system, 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 111, Paragraph A of

In the event that the facilities fail to perform satisfactorily, including the creation of
nuisance conditions, the Permittee shall take immediate corrective action, including those as ma4.
