(A) If any wastewater is discharged or proposed to be discharged to the public sewer which exceeds the normal concentrations of wastes, or which contains the substances or possesses the characteristics enumerated in § 52.04 and which in the opinion of the Water and Sewer Superintendent/Village Administrator may have a deleterious effect upon the wastewater treatment works or receiving waters, including a violation of applicable water quality standards, or which may otherwise create a hazard to life or constitute a public nuisance, the Water and Sewer Superintendent/Village Administrator may take any or all of the following actions:
(1) Reject the waste and/or prohibit the further discharge of the waste;
(2) Require pretreatment to an acceptable condition for discharge to the public sewer;
(3) Require control over the quantities and rates of discharge; and/or
(4) Require payment by the user causing said discharge to cover the added cost of handling and treatment of the wastewater so discharged.
(B) All industrial wastes discharged to the public sewer by major contributing industries shall at a minimum meet the national pretreatment standards or best practical control technology currently available for incompatible pollutants as promulgated pursuant to § 307(b) of the Clean Water Act (33 U.S.C. § 1317(b)), unless the village is committed by its NPDES permit to remove a specified percentage of the incompatible pollutant. In those instances, the applicable pretreatment standards may be correspondingly reduced to levels determined by the Water and Sewer Superintendent/Village Administrator or by the EPA.
(C) If the Water and Sewer Superintendent/Village Administrator requires pretreatment or equalization of waste flow, the design and installation of the pretreatment equipment shall be subject to the review and approval of the Water and Sewer Superintendent/Village Administrator and the EPA, and subject to the requirements of all applicable codes, ordinances and laws.
(D) Where pretreatment or flow-equalizing facilities are provided or required for all wastes, they shall be maintained continuously in satisfactory and effective operation by the user at the user’s expense.
(E) Grease, oil and sand interceptors shall be provided by the user when, in the opinion of the Water and Sewer Superintendent/Village Administrator, they are necessary for the proper handling of wastewater containing excessive amounts of grease and oil, or sand; except such interceptors shall not be required for residential users. All interception units shall be of type and capacity approved by the Water and Sewer Superintendent/Village Administrator.
(F) Within 90 days after passage of this chapter, each person whose operation entails the discharge of industrial wastes or other wastewaters deemed to be significant by the Water and Sewer Superintendent/Village Administrator to the public sewer shall prepare and file with the Water and Sewer Superintendent/Village Administrator a written statement setting forth the nature of the operation contemplated or presently carried on, the amount and source of water required for use, the proposed point of discharge of said wastes into the wastewater collection system of the village, the estimated amount to be so discharged and a statement setting forth expected bacterial, physical, chemical and other known characteristics of said wastes. After the passage of this chapter, every new commercial and industrial user or other wastewaters deemed to be significant by the Water and Sewer Superintendent/Village Administrator that applies to the village for sewer service shall provide said information with said application. Within a reasonable time of receipt of such statement, the Water and Sewer Superintendent/Village Administrator shall make an order stating such minimum restrictions as in the Water and Sewer Superintendent/Village Administrator’s opinion may be necessary to adequately guard against unlawful uses of the village’s treatment works by each of said persons.
(G) When circumstances exist which would place an unreasonable burden on the person to comply with the time schedule imposed by division (F) of this section, a written request for an extension of time stating the reasons for such a request may be presented for the consideration of the Water and Sewer Superintendent/Village Administrator. No extension of time shall exceed 90 days.
(H) Nothing in this chapter shall prevent any special agreement or arrangement between the village and any user whereby an industrial waste of unusual strength or character may be accepted by the village for treatment, subject to possible payment therefor by the user.
