(A) Persons discharging industrial wastes which exhibit none of the characteristics of wastes prohibited previously, other than excessive BOD or suspended solids, but having a concentration for a duration of 15 minutes greater than four times that of normal sewage as measured by suspended solids and BOD or an average concentration during a normal working day of the permittee’s industry of suspended solids or BOD content in excess of normal sewage as defined in this subchapter shall be required to pretreat the industrial wastes to meet the requirements of normal sewage; however, such wastes may be accepted for treatment if the following requirements are met.
(1) The waste will not cause damage to the collection and treatment facilities.
(2) The waste will not impair the treatment process.
(3) The person who discharges such waste enters into an industrial sewer connection application and agrees to pay the sewer service charge and industrial waste surcharge.
(B) The person who discharges such wastes shall enter into an industrial sewer connection application with the town providing for a surcharge over and above published water and sewer rates. The basis for the surcharge on industrial wastes is a capital and operating cost of $0.12 per part per million gallons for the BOD (biochemical oxygen demand) and a capital and operating cost of $0.36 per part per million gallons for the suspended solids exceeding normal sewage. The cost of the chlorination is based on the town’s contract cost of chlorine per pound per million gallons for each part exceeding the five parts of normal sewage. These rates shall continue until changed by action of the Town Council. The surcharge shall be calculated for billing purposes with the following formula:
SC = [0.12 (BOD -240) + 0.36 (SS1 -- 240) + 8.345PC (C-5)]
Where:
SC = Surcharge in dollars for time related to volume
V = Volume in million gallons based on metered water
BOD = 5-day at 20°C of industrial waste (ppm)
SS1 = Suspended solids of industrial waste (ppm)
Pc = Town’s contract price of chlorine per pound
C = Chlorine demand of the industrial waste (ppm)
(C) Any person who refuses to comply with or who resists or willfully discharges wastes prohibited from discharge into public sewers or who refuses to comply with the provisions of this section shall be served by the approving authority with a written notice stating the nature of the violation and providing a reasonable time limit for satisfactory correction thereof.
(1) Any person who shall continue any violation beyond the time limit shall be guilty of violation of his or her industrial sewer connection application and shall be summarily disconnected from the sanitary or water service, such disconnection and reconnection to be at the total expense of the customer.
(2) Where acids or chemicals damaging to sewer lines or treatment process are released to the sewer and cause rapid deterioration of these structures or interfere with the proper treatment of sewage, the approving authority is authorized to immediately terminate service by such measures as are necessary to protect the facilities.
