(A) No person shall discharge, or cause to be discharged, to any of the town’s wastewater facilities any substances, materials, waters, or wastes in quantities or concentrations that will:
(1) Create a fire or explosion hazard including, but not limited to, gasoline, benzene, naphtha, fuel oil, or other flammable or explosive liquid, solid, or gas;
(2) Cause corrosive damage or hazard to structures, equipment, or personnel of the wastewater facilities, and in no case will discharge be allowed with a pH lower than 5.0. These requirements may be modified for facilities designed to accommodate greater ranges:
(a) Having a pH lower than 5.0 or greater than 10.0 for more than 5% of the time in a 24-hour period; or
(b) Having a pH lower than 3.5 or greater than 12.0 for a period exceeding 15 minutes.
(3) Cause obstruction to the flow in sewers or other interference with the operation of wastewater facilities due to accumulation of solid viscous materials including, but not limited to: wood, glass, ashes, sand, cinders, unshredded garbage, paper products such as cups, dishes, napkins, milk containers, and the like, either whole or ground by garbage grinders;
(4) Constitute a raw discharge or substantial deviation from normal rates of discharge (slug discharge) sufficient to cause interference in the operation and performance of the wastewater facilities;
(5) Contain heat in amounts that will accelerate the biodegradator of wastes, causing excessive amounts of hydrogen sulfide to form in the wastewater sewer, or inhibit biological activity in the wastewater treatment facilities, and in no case shall the discharge of heat cause the temperature in the town’s wastewater sewer to exceed 58°C or 150°F or the temperature of the influent to the treatment facilities to exceed 40°C or 104°F, unless the facilities can accommodate such heat;
(6) Contain more than 100 milligrams per liter of nonbiodegradable oils of mineral or petroleum origin;
(7) Contain floatable oils, fat, or grease;
(8) Contain toxious, malodorous gas, or substance in quantities that create a public nuisance or a hazard to life;
(9) Contain radioactive wastes in harmful quantities as defined by applicable state and federal guidelines;
(10) Contain any garbage that has not been properly shredded; and/or
(11) Contain any odor or color-producing substances exceeding concentration limits that may be established by the utility’s Superintendent to the town’s NPDES permit.
(B) If the drainage or discharge from any establishment causes a deposit, obstruction, or damage to any of the town’s wastewater facilities, the utility’s Superintendent shall cause the deposit or obstruction to be promptly removed or cause the damage to be promptly repaired. The cost for such work, including materials, labor, and supervision, shall be borne by the person causing such deposit, obstruction, or damage. The Clerk-Treasurer is authorized to pursue legal action through the county courts to recover such costs.
(C) Stormwater shall be discharged to such sewers as are specifically designated as storm sewers or to a natural outlet approved by the utility’s Superintendent and other regulatory agencies. Unpolluted industrial cooling or process waters may be discharged, on approval of the Superintendent and other regulatory agencies, to a storm sewer or natural outlet.
(D) When required by the utility’s Superintendent, the owner of any property discharging industrial wastes and the owner of any property containing multiple-family dwellings shall be required to 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 accessibly and safely located, and shall be constructed in accordance with plans approved by the utility’s Superintendent. The manhole shall be maintained by the owner so as to be safe and accessible at all times.
