(2)

Those containing any odor- or color-producing substances exceeding concentration limits which may be established for purposes of meeting the SPDES permit.

Those containing radioactive wastes or isotopes of such half-life or concentration as may exceed limits established by the Administrator in compliance with applicable Village, state and federal regulations.

(4)

Those containing floatable oils, fat or grease.

(5)

Those containing suspended and/or dissolved solids of such character and quantity that unusual attention or expense is required to handle such materials at the sewage treatment plant.

(6)

Those whose discharge by any user results in an average daily flow greater than 5% of the average daily flow in the Village sewer system.

(7)

Those having a BOD greater than 300 parts per million or 300 milligrams per liter.

(8)

Those having a chlorine demand greater than 25 milligrams per liter.

(9)

Those having a chemical oxygen demand greater than 600 milligrams per liter.

(10)

Those containing more than 350 parts per million or 350 milligrams per liter of suspended solids.

(11)

Those from garages and motor-vehicle-washing establishments. Washing facilities shall be roofed over and shall be equipped with an interceptor approved by the Administrator.

(12)

Those from any establishments serving 50 or more meals per day. Every sink, dish-washing machine or other equipment for cleaning dishes, cooking utensils and cooking shall be connected to the building drain through an interceptor approved by the Administrator.

Plans, specifications and any other pertinent information relating to proposed preliminary treatment facilities shall be submitted for the approval of the Administrator, and no construction of such facilities shall be commenced until said approval is obtained in writing.

Required preliminary treatment facilities shall be constructed wholly at the expense of the property owner and shall be maintained continuously in satisfactory and effective operation at his expense.

To assure compliance with the terms and conditions of his approval, the Administrator may require, at the property owner's expense, monitoring of discharges. Such monitoring may involve the installation, use and maintenance of manholes and monitoring equipment, recordkeeping and reporting.

(1)

Such records shall be made available, upon request by the Administrator, to other agencies having jurisdiction over discharges to the receiving waters.

(2)

All measurements, tests and analysis of the characteristics of waters and wastes shall be made in accordance with Standard Methods for the Examination of Water and Sewage as published by the American Public Health Association and shall be made at a manhole in the building sewer, or if no such manhole has been required, then at the nearest downstream manhole in the Village sewer.

To be approved by the Administrator, a preliminary treatment facility must reduce objectionable characteristics or constituents to within the maximum limits provided for waters or wastes under this section, unless the discharger is required to pay, under the provisions of this section, for the added costs to the Village of reducing objectionable characteristics or constituents to within the maximum limits.

If no approved preliminary treatment occurs, the Administrator shall either:

(1)

Reject the waters and/or wastes; or

(2)

Accept the waters and/or wastes and require payment by the discharger in excess of ordinary user fees or sewer charges or rents to cover the added cost to the Village of handling and treating the waters and/or wastes.

Any substantial change in the volume or character of discharges is subject to all the provisions of this chapter.

§ 234-34 Notification of prohibited discharge.

Any user who discharges wastes in violation of this chapter shall immediately notify the Administrator. Notification shall be followed within 15 days by a detailed, written statement describing the causes of the discharge and the measures taken to prevent future occurrences. Such notification will not serve to relieve the user of liability for any expense, loss or damage to the Village disposal system or for any fines.
