(A) No user shall discharge or deliver any substance into the town’s municipal sewer system that is not qualifying waste, which is hereby defined as that waste which complies with present and hereafter existing requirements of applicable authority (including, but not limited to, then existing ordinances, rules and regulations of the town and/or standards applicable to and/or defining prohibited discharges into the system, and/or unacceptable volumes and/or strengths of the substances).
(B) Without limiting the generality of the foregoing, qualifying waste shall not include:
(1) Any material having a temperature higher than 65°C, or which may solidify or become viscous at temperature between 0° and 65°C, or any wastewater having a temperature which will inhibit biological activity in the POTW resulting in interference. In no case, wastewater with a temperature at the introduction into the POTW which exceeds 40°C or 104°F;
(2) Any material which contains more than 100 parts per million, by weight, of fat, wax, oil or grease, whether emulsified or not;
(3) Any flammable or explosive material;
(4) Any material capable of causing obstruction to the flow in sewers or other interference with the proper operation of the sewage works;
(5) Any material having a pH lower than 6.0 or higher than 9.0, or having any other corrosive property capable of causing damage or hazard to structures, equipment, operation and/or personnel of the system;
(6) Any noxious or malodorous gas or substance which will probably create a public nuisance;
(7) Storm, surface, ground or cooling water, roof run off or subsurface drainage;
(8) Any matter containing toxic or poisonous substance in sufficient quantity, or containing suspended solids of the character and quality, as to be likely to result in the injury or interference with any treatment process then being used by system, or constituting a hazard to living things, or to the receiving waters of the treatment facility, or requiring unusual attention or expense to handle the materials at the treatment facility. Without limiting the generality of the foregoing, the same shall include:
(a) Any material containing strong acid iron pickling wastes, or concentrated plating solutions whether neutralized or not;
(b) Any material containing toxic pollutants, or wastes exerting an excessive chlorine requirement, to the degree that any material received in the composite sewage at the treatment facility exceeds the limits established by applicable authority for the materials. Without limiting the generality of the foregoing, qualifying waste shall not contain any of the following:
1. More than 0.10 parts per million of cadmium;
2. More than 2.32 parts per million of chromium;
3. More than 0.20 parts per million of copper;
4. More than 0.22 parts per million of cyanide;
5. More than 0.40 parts per million of lead;
6. More than 4.1 parts per million of nickel;
7. More than 4.2 parts per million of zinc; and
8. Other corrosive substances capable of causing damage or hazard to structures, equipment and/or personnel of the sewage utility.
(c) Any material containing phenols or other taste or odor producing substances, in concentrations exceeding limits which may be established by applicable authority as appropriate, after treatment of the composite sewage, to meet the requirements of public agencies of jurisdiction for the discharge to the receiving waters of the treatment facility; and
(d) Any radioactive wastes or isotopes of the half life or concentration as may exceed limits established by applicable authority.
(9) Any pollutant, including oxygen demanding pollutants (BOD, and the like) released in a discharge at a flow rate and/or pollutant concentration which will cause interference with the POTW; and
(10) Any substance with objectionable color not removed in the treatment process.
