Flow equalization.

No person shall cause the discharge of slugs to the POTW. Each user discharging, into the POTW, greater than 100,000 gallons per day will be required to obtain a permit. The owner may be required to install and maintain, on his property and at his expense, a storage and flow control facility acceptable to the Chief Plant Operator and/or Superintendent of Sewers to insure equalization of flow over a twenty-four-hour period. A wastewater discharge permit may be issued solely for flow equalization.
