(A) Connection and use permit. No person shall discharge or cause to be discharged any wastes or wastewaters in the village’s wastewater facilities without first obtaining the appropriate connection and use permit from the DPW Supervisor in accordance with § 50.06(A) of this code.
(B) Restricted discharges. No person shall discharge or cause to be discharged to any of the village wastewater facilities any substances, materials, waters or wastes in quantities or concentrations which:
(1) Will create a fire or explosion hazard (including substances such as gasoline, benzene, naptha, fuel oils or other flammable or explosive liquids, solids or gases);
(2) Will cause corrosive damage or hazard to structures, equipment or personnel of the village wastewater facilities;
(3) Have a pH lower than 5.0 or greater than 10.0 for more than 10% of the time in a 24-hour period;
(4) Have a pH lower than 3.5 or greater than 12.0 for any period exceeding 15 minutes;
(5) Will cause obstruction to the flow in sewers or other interference with the operation of wastewater facilities due to accumulation of solid or viscous materials;
(6) Will constitute a rate of discharge and/or concentration which substantially deviates from normal rates of discharge, thereby creating a slug discharge sufficient in magnitude to cause interference with the operation and performance of the wastewater facilities;
(7) Contain heat in amounts which will accelerate the biodegradation of wastes, causing the formation of excessive amounts of hydrogen sulfide in the wastewater sewer or inhibiting biological activity in the wastewater treatment facilities, or which will cause the temperature in the wastewater sewer to exceed 58°C (150°F) or the temperature of the influent to the treatment facilities to exceed 40°C (104°F) unless the facilities can accommodate the heat;
(8) Contain more than 100 milligrams per liter of non-biodegradable oils of mineral or petroleum origin;
(9) Contain floatable oils, fat or grease;
(10) Contain a noxious, malodorous gas or substance which is present in quantities that create a public nuisance or a hazard to life;
(11) Contain radioactive wastes in harmful quantities as such quantities are defined by applicable state and federal regulations;
(12) Contain any garbage that has not been properly shredded; or
(13) Contain any of the following concentrations:
Ammonia nitrogen | More than 25 mg/l |
BOD | More than 250 mg/l |
Phosphorus | More than 10 mg/l |
SS | More than 250 mg/l |
(C) Special agreements. Nothing in this section shall be construed as preventing a special agreement or arrangement between the village and any user of the wastewater facilities whereby wastewater otherwise prohibited by this section is accepted into the system if the DPW Supervisor determines that the wastewater facilities are capable of handling the discharges. Any like agreement or arrangement shall contain provisions whereby the user shall pay a surcharge, which surcharge shall be according to rates established by resolution of the Village Council, and which shall compensate the village for added treatment costs made necessary by the excess constituent discharged. A continued violation of the terms of the agreement, after notice of the violation as provided in § 50.03(D) of this code, shall be a violation of this section, punishable as provided in § 50.99 below.
(D) Alternate limits. Where it appears to the DPW Supervisor that the purposes of this section would be served by establishing alternate limits for individual users of the village’s wastewater facilities, the DPW Supervisor may approve mass limits of a stringency comparable to those limits established in this section for purposes of providing a more practical means of discharge monitoring or for recognizing the impact of water conservation on discharge concentrations.
