(a) No person shall discharge or cause to be discharged any storm water, surface water, groundwater, roof runoff, subsurface drainage, uncontaminated cooling water, or unpolluted industrial process waters to any sanitary sewer. All existing connections allowing such discharge may be reviewed and approved or rejected by the Director upon consideration of the resulting hardships and related factors.
(b) Non-contact cooling water may be discharged to a storm sewer or natural outlet. Non-contact cooling water may be discharged to a combined sewer only with approval of the Director.
(c) Pursuant to 40 CFR 403.8(f)(1)(B)(1-6) and OAC 3745-03-03(C)(1)(c)(ivi), individual wastewater discharge permits and general permits must contain:
(1) A statement that indicates the wastewater discharge permit issuance date, expiration date and effective date;
(2) Effluent limits, including Best Management Practices, based on applicable Pretreatment Standards
(3) Self monitoring, sampling, reporting, notification, and recordkeeping requirements. These requirements shall include an identification of pollutants (or best management practice) to be monitored, sampling location, sampling frequency, and sample type based on Federal, State, and local law.
(4) A statement of applicable civil and criminal penalties for violation of Pretreatment Standards and Requirements, and any applicable compliance schedule. Such schedule may not extend the time for compliance beyond that required by applicable Federal, State, or local law.
(5) Requirements to control Slug Discharge, if determined by the Director to be necessary.
(d) No person shall discharge or cause to be discharged any of the following described waters or wastes to any public sewers:
(1) Any liquids, solids, or gasses which by reason of their nature or quantity are, or may be, sufficient either alone or by interaction with other substances to cause fire or explosion or be injurious in any other way to the sewer system or the POTW or to the operation of the POTW, including, but not limited to, waste-streams with a closed cup flashpoint of less than 140 degrees Fahrenheit or 60 degrees Celsius using the test method specified in 40 CFR 261.21. Prohibited substances include, but are not limited to, gasoline, kerosene, naphtha, benzene, toluene, xylene, ethers, ketones, aldehydes, peroxides, chlorates, alcohols, bromates, carbides, hydrides, perchlorates, sulfides and any other substance which the City, the state, or EPA has notified the user is a fire hazard or hazard to the system.
(2) Any waters or wastes containing toxic or poisonous pollutants as solids, liquids, or gases in sufficient quantity, either singly or by interaction with other wastes, to injure or interfere with any sewage treatment process, constitute a hazard to human or animals, create a public nuisance or create any hazard in the receiving waters of the POTW.
(3) Any waters or wastes having a corrosive property capable of causing damage or hazard to structures, equipment, and personnel of the sewage works.
(4) Solid or viscous substances in quantities or of such size capable of causing obstruction to the flow in sewers, or other interference with the proper operation of the sewage works, such as, but not limited to, ashes, cinders, sand, mud, straw, shavings, metal, wood, glass, rags, feathers, tar, flashings, entrails, and paper dishes, cups, milk containers, etc., either whole or ground by garbage grinders.
(5) Any waters or wastes containing objectionable or toxic substances in excess of the allowable limits determined by the Director and listed in the "Index of Restricted Substances" posted at the Wastewater Treatment Plant, the City Service Center and on the City's website.
(6) Any waters or wastes which may cause the POTW to exceed NPDES Permit conditions.
(e) No discharger shall increase the use of potable or process water in any way, nor mix separate waste streams for the purpose of diluting a discharge to partially or completely substitute adequate treatment to achieve compliance with the standards set forth in this ordinance.
(f) No person shall discharge any hazardous wastes to the POTW by truck, rail, or dedicated pipeline. Industrial dischargers are required to notify the POTW if they are disposing of any Resource Conservation and Recovery Act (RCRA) listed or characteristic hazardous wastes, as defined in 40 CFR 261, by discharging it into the POTW. Exempt from this notification requirement are these industrial dischargers who discharge 15 kilograms or less per month of non-acute hazardous wastes. All industrial dischargers shall promptly notify the Director in advance of any substantial changes in the volume or character of pollutants in their discharge, including the listed or characteristic hazardous wastes for which the industrial discharger has submitted initial notification under 40 CFR 403.12(p).
(g) No person shall discharge or cause to be discharged the following described substances, materials, waters, or wastes if it appears likely in the opinion of the Director that such wastes can harm either the sewers, sewage treatment process or equipment, have an adverse effect on the receiving stream or can otherwise endanger life, limb, public property or constitute a nuisance. In forming his opinion as to the acceptability of these wastes, the Director will give consideration to such factors as the quantities of subject wastes in relation to flows and velocities in the sewers, materials of construction of the sewers, nature of sewage treatment process, capability of the POTW, and other pertinent factors. The substances prohibited are:
(1) Any liquid or vapor having a temperature higher than 150 degrees Fahrenheit, or 65 degrees Celsius at the discharge point into the sewer and/or any temperature which would cause the POTW to have an influent temperature of 104 degrees Fahrenheit or 40 degrees Celsius at any time.
(2) Any water or wastes containing substances which may solidify or become viscous at temperatures between 32 degrees and 150 degrees Fahrenheit, or between 0 degrees and 65 degrees Celsius.
(3) Any garbage that has not been properly shredded. The installation and operation of any garbage grinder equipment with a motor of three-fourths horsepower or greater shall be subject to the review and approval of the Director.
(4) Any waters or wastes containing strong acid iron pickling wastes, or concentrated plating solutions.
(5) Any waters or wastes containing taste or odor producing substances in such concentrations as exceed limits which may be established by any State, Federal, or other public agency having jurisdiction over the discharge of such substances to the receiving waters.
(6) Any radioactive waste or isotopes of such half-life or concentration as may exceed limits established by the Director in compliance with applicable State or Federal regulations.
(7) Materials which exert or cause:
A. Unusual concentration of inert suspended solids (such as, but not limited to, Fullers earth, lime slurries, and lime residue) or of dissolved solids, (such as, but not limited to, sodium chloride and sodium sulfate).
B. Excessive discoloration, such as, but not limited to, dye wastes and vegetable tapping solutions.
C. Unusual requirements of BOD, suspended solids, or chlorine demand in such quantities as to constitute a significant load on the POTW.
D. Unusual volume of flow or concentration of wastes constituting "slugs" as defined in Section 916.01(pp).
(8) Waters or wastes containing substances which are not amenable to treatment or reduction by the sewage treatment processes employed, or are amenable to treatment only to such degree that the POTW effluent cannot meet the requirements of other agencies having jurisdiction over the discharge of such substances to the receiving waters or will contaminate the sludge thereby rendering it unsuitable for reclamation.
(h) No discharger subject to the National Categorical Pretreatment Standards as promulgated by the U.S. Environmental Protection Agency (USEPA) shall fail to meet by the applicable standards.
(i) The Director is authorized to establish Local Limits pursuant to 40 CFR 403.5(c-d) and OAC 3745-3-03(C)(4).
(j) The pollutant limits, recorded in the Manager's Journal, are established to protect against Pass Through and Interference. No person shall discharge wastewater containing in excess of those limits.
(k) The Director may develop Best Management Practices (BMPs), by ordinance, in individual wastewater discharge permits, or general permits, to implement Local Limits and other requirements in this section.
