(A) If any liquid, substance, or gas is discharged or is proposed to be discharged into the public sewer which contains the substances or possesses the characteristics enumerated in § 51.31, and which, in the judgment of the Engineer, may have a deleterious effect upon the sewage works, processes, equipment, or receiving waters, or which otherwise create a hazard to life or constitute a public nuisance, the Engineer may do the following.
(1) Reject the wastes.
(2) Require pretreatment to an acceptable condition for discharge to the public sewer.
(3) Require control over the quantities and rates of discharge.
(B) When a proposal is made for the pretreatment or equalization of waste flows, the design and installation of the plants and equipment shall be subject to review and approval by the Engineer, and subject to the requirements of all applicable codes, ordinances, and laws.
(1) Plans, specifications, expected performance data, and any other pertinent information relating to holding tanks or to pretreatment facilities, shall be prepared by a licensed professional engineer and submitted for the approval of the Water Pollution Control Authority, and no construction of such facilities shall be commenced until the approvals are obtained in writing. The Engineer shall approve the holding tanks, or pretreatment facilities provided the same shall indicate that an effluent conforming to the provisions of this chapter will be provided. If, after the installation of the facilities has been completed and operation begun, the facilities do not produce the expected performance, the Engineer shall have the right to order the owner to cease operation until such time that modifications are made to enable the facilities to perform properly.
(2) Prior to discharge or permission to discharge into the town public sewers, the applicant must obtain written permission from the Water Pollution Control Authority, in the form of a permit allowing the proposed discharge, and must, if required by the town, install suitable pretreatment facilities and operate and maintain such facilities in a manner which will insure a continuous and satisfactory effluent.
(C) Where preliminary treatment facilities are provided for any waters or wastes, they shall be maintained continuously in satisfactory and effective operation by the owner at his own expense and shall be subject to periodic inspection by the Engineer and shall be of a type and capacity approved by the Engineer, provided they produce an effluent conforming to the provisions of this chapter. The owner shall maintain operating records and shall submit to the Engineer a monthly summary report of the character of the influent and effluent as may be prescribed by the Engineer to show satisfactory performance of the treatment facilities.
(D) For the purpose of measurement, the acceptability of pretreated industrial waste will be measured at the point where the industrial waste leaves a pretreatment facility, and before dilution with any other waste stream or process water.
(Ord. 235, adopted 9-4-84)
Grease, oil, and sand interceptors shall be provided when, in the opinion of the Engineer, they are necessary for the proper handling of liquid wastes containing grease in excessive amounts, or any flammable wastes, sand, or other harmful ingredients except that such interceptors shall not be required for private living quarters or dwelling units. All interceptors shall be of a type and capacity approved by the Engineer and shall be located as to be readily and easily accessible for cleaning and inspection.
(Ord. 235, adopted 9-4-84) Penalty, see § 51.99
When required by the Engineer, the owner of any property serviced by a building sewer carrying industrial wastes, shall install a suitable control manhole together with such necessary meters and other appurtenances in the building sewer to facilitate observation, sampling, and measurement of the wastes. Such manhole, when required, shall be accessible and safely located, and shall be constructed in accordance with the plans approved by the Engineer. The manhole shall be installed by the owner at his expense, and shall be maintained by him so as to be safe and accessible at all times.
(Ord. 235, adopted 9-4-84) Penalty, see § 51.99
(A) All measurements, tests, and analyses of the characteristics of waters and wastes to which reference is made in this chapter shall be determined in accordance with the latest edition of "Standard Methods for the Examination of Water and Waste Water", published by the American Public Health Association, and shall be determined at the control manhole provided, or upon suitable samples taken at the control manhole. In the event that no special manhole has been required, the control manhole shall be considered to be the nearest downstream manhole in the public sewer to the point at which the building sewer is connected. Sampling shall be carried out by customarily accepted methods to reflect the effect of constituents upon sewage works and to determine the existence of hazards to life, limb, and property. The particular analyses involved will determine whether a 24-hour composite of all outfalls of a premise is appropriate or whether a grab sample or samples should be taken. Normally, but not always, B.O.D. and suspended solids analysis are obtained from 24-hour composites of all outfalls, whereas pH's are determined from periodic grab samples.
(B) Any new discharge from a single source of domestic wastewater in excess of 5,000 gallons per day, or cooling waters, must be authorized by a permit from the State Department of Environmental Protection, director of Water Compliance and Hazardous Substances.
(Ord. 235, adopted 9-4-84) Penalty, see § 51.99
