Such authority may be contained in the statute, ordinance, or series of contracts or joint powers agreements, which the POTW is authorized to enact, enter into, or implement, and which are authorized by state law. At a minimum, this legal authority shall enable the POTW to:
A. Deny or condition new or increased contributions of pollutants, or changes in the nature of pollutants, to the POTW by industrial users where such contributions do not meet applicable pretreatment standards and requirements or where such contributions would cause the POTW to violate its NPDES permit.
B. Require compliance with applicable pretreatment standards and requirements by industrial users.
C. Carry out all inspection, surveillance and monitoring procedures necessary to determine, independent of information supplied by industrial users, compliance or noncompliance with applicable pretreatment standards and requirements by industrial users. Representatives of the POTW shall be authorized to enter any premises of any industrial user in which a discharge source or treatment system is located or in which records are required to be kept under paragraph (A)(2) of rule 3745-3-06 of the Administrative Code to assure compliance with pretreatment standards. Such authority shall be at least as extensive as authority provided under Section 308 of the Act.
D. Obtain remedies for noncompliance by any industrial user with any pretreatment standard and requirement. All POTWs shall be able to seek injunctive relief for noncompliance by industrial users with pretreatment standards and requirements. All POTWs shall also have authority to seek or assess civil or criminal penalties in at least the amount of one thousand dollars ($1,000.00) per day for each violation by industrial users of pretreatment standards and requirements.
(2) Providing, however, no person, firm or corporation shall contribute, discharge or cause to be discharged, directly or indirectly, any of the following described substances into the Village’s sewage disposal system:
A. Pollutants introduced into POTWs by an industrial user shall not pass through the POTW or interfere with the operation or performance of the POTW. These general prohibitions and the specific prohibitions in division (b)(2) of this section apply to all sources of indirect discharge whether or not the source is subject to other national, state, or local pretreatment standards or requirements.
B. The following described substances shall not be introduced into a POTW:
1. Pollutants which create a fire or explosion hazard in the POTW including, not limited to, waste streams with a closed cup flashpoint of less than 140 degrees Fahrenheit or 60 degrees Celsius using the test methods specified in 40 C.F.R. 261.21;
2. Pollutants which will cause corrosive structural damage to the POTW, but in no case discharges with pH lower than 5.0, unless the POTW is specifically designed to accommodate such discharges;
3. Solid or viscous pollutants in amounts which will cause obstruction to the flow in sewers, or other interference with the operation of the POTW;
4. Any pollutant, including oxygen-demanding pollutants, released in a discharge at a flow rate and/or pollutant concentration as to cause interference in the POTW;
5. Heat in amounts that will inhibit biological activity in the POTW treatment plant resulting in interference or causing damage, but in no case heat in such quantities that the temperature exceeds 40 degrees Celsius (104 degrees Fahrenheit) at the POTW treatment plant unless the Village Administrator, upon request of the POTW, approves an alternate temperature limit;
6. Petroleum oil, nonbiodegradable cutting oil, or products of mineral oil origin in amounts that will cause interference or pass through;
7. Pollutants which result in the presence of toxic gases, vapors, or fumes within the POTW in a quantity that may cause acute worker health and safety problems;
8. Any trucked or hauled pollutants, except at discharge points designated by the POTW;
9. Any clean water connections (i.e. downspouts, foundation drains, sump pumps, etc.); and
10. Any batch discharge facility shall not discharge during heavy rain events when there are sewer overflows occurring.
(c) Usage Measurement Methods.
(1) For any lot, parcel of land, building or premises having or being served by any connection to the Village’s sanitary sewerage system, intercepting sewers and sewage treatment or disposal plant or part thereof, or otherwise discharging sanitary sewage industrial wastes, water or other liquid, either directly or indirectly into the Village’s sanitary sewerage system, the charge or rental shall be based upon the quantity of water used as measured by the Village water meter therein in use, and the quantity of water used and waste discharged as determined by the Village’s sewer rate ordinance and the whole reduced by any deductions as determined by the Village’s sewer rate ordinance.
(2) On premises using water, either all or in part, from sources other than the waterworks system of the Village and not measured by the Village water meter or other meter acceptable to the Village Administrator, the quantity of water consumed shall be measured by a meter installed and maintained for such purpose at the expense of the owner or other interested party and acceptable to the Village Administrator; or the owner or other interested party may, at his or her option, request the Village Administrator to determine the amount of water consumed on the premises in accordance with accepted engineering practices, and the quantity of water consumed on the premises shall be the amount so measured by such meter or so determined by the Village Administrator.
(3) In the event the Village Administrator is satisfied that a portion of the water from any source consumed upon any premises does not and cannot enter the system, then in such case the owner or other interested party may, at his or her expense, install and maintain such separate metering devices, or provide such data in conformity with accepted engineering practices, as shall demonstrate to the satisfaction of the Village Administrator, that portion of the water so consumed which is discharged into the system, and such portion shall be the basis for measuring the sewer charge under the Village’s sewer rate ordinance, if applicable.
