(a) Discharge Reports.
(1) Every significant industrial user shall file a periodic discharge report at such intervals as are designated by the Superintendent. The Superintendent may require any other industrial users discharging or proposing to discharge into the treatment system to file such periodic reports.
(2) The discharge report shall include, but, in the discretion of the Superintendent, shall not be limited to, nature or process, volume, rate flows, mass emission rate, production quantities, hours of operation, concentrations of controlled pollutants or other information which relates to the generation of waste. Such reports may also include the chemical constituents and quantity of liquid materials stored on site even though they are not normally discharged. In addition to discharge reports, the Superintendent may require information in the form of self monitoring reports.
(b) Records and Monitoring.
(1) All industrial users who discharge or propose to discharge waste water to the waste water treatment systems shall flow, and pollutant amounts or concentrations as are necessary to demonstrate compliance with the requirements of this chapter and any applicable state or Federal pretreatment standards or requirements.
(2) Such records shall be made available upon request by the Superintendent. All such records relating to compliance with pretreatment standards shall be made available to officials of the U.S. Environmental Protection Agency upon demand. A summary of such data indicating the industrial user’s compliance with this chapter shall be prepared as requested and submitted to the Superintendent.
(3) The owner or operator of any premises or facility discharging industrial wastes into the system shall install at his own cost and expense suitable control manholes or access points, and monitoring equipment to facilitate the accurate observation, sampling and measurement of waste. Such equipment shall be maintained in proper working order and kept safe and accessible at all times. Sampling methods, location, times, durations, and frequencies are to be determined on an individual basis subject to approval by the Superintendent.
(4) Waste water volume determination. The volume of flow used for computing industrial waste surcharges shall be metered water consumption of the person except as herein provided in this paragraph.
If the person discharging industrial wastes into the public sewers procures any part, or all, of this water from sources other than a metered, public water system, all or part of which is discharged into the public sewer, the person shall install and maintain at his expense water meters of a type approved by the engineer or Superintendent for the purpose of determining the volume of water obtained from those other sources. Access to these meters shall be made available to representative of the Village of any reasonable time. The accuracy of said meters shall be verified at the discharger’s expense on a once per two year basis at a minimum or at the request of the Superintendent, by an independent testing company.
The engineer or Superintendent may require the installation of devices for measuring the volume of waste discharge if volumes cannot otherwise be determined from the metered water consumption records. Any metering devices for determining the volume of waste discharge to the public sewer shall be installed, owned and maintained by the person responsible for its discharge following approval and installation, such meters may not be removed without the consent of the engineer or Superintendent.
(5) The monitoring equipment shall be located and maintained on the industrial user’s premises outside of the building. When such a location would be impractical or cause undue hardship on the user, the Superintendent may allow such facility to be constructed in the public street or sidewalk area with the approval of the public agency having jurisdiction over such street or sidewalk, and located so that it will not be obstructed by public utilities, landscaping or parked vehicles.
(6) Whether constructed on public or private property the monitoring facilities shall be constructed in accordance with the Superintendent’s requirements and all applicable construction standards and specifications.
(c) Inspection, Sampling and Analysis.
(1) Compliance determination. Compliance determinations with respect to Section 925.02 prohibitions and limitations may be made on the basis of either instantaneous grab samples to composite samples of waste water. Composite samples may be taken over a 24 hour period, or over a longer or shorter time span as determined necessary by the Superintendent to meet the needs of specific circumstances.
Sampling and monitoring industrial wastes discharged into the public sewers shall be subject to periodic inspection with a determination of character and concentration of said wastes. The testing will be performed as often as may be deemed necessary by the engineer or Superintendent but in no case less than two 24 hour composite samples per month. The owner shall be responsible for the collection and testing of the aforementioned samples.
Samples shall be collected in such a manner as to be representative of the composition of the wastes. The sampling shall be accomplished by the use of automatic sampling equipment capable of collecting composite samples. Access to sampling locations shall be granted to the engineer or his authorized representative or Superintendent at all tines. Every care shall be exercised in the collection of samples to insure preservation in a state comparable to that at the time the same was taken.
(2) Analysis of industrial waste water. Laboratory analysis of industrial waste water samples shall be performed in accordance with the current edition of “Standard Method” of the “Methods for Chemical Analysis of Water and Waste” published by the U.S. EPA. Analysis of those pollutants not covered by these publications shall be performed in accordance with procedures established by the State EPA. However, alternative methods for certain analysis of industrial waste may be used subject to mutual agreement between the engineer or Superintendent and the person responsible for its discharge. Determination of the character and concentration of the industrial waste shall be made by the person responsible for the discharge, or his qualified agent as approved by the engineer or Superintendent. The results of the analyses shall be reported to the Village on a monthly basis on forms provided by the Village. The Village shall make its own analyses on the waste and these determinations shall be binding as a basis for charges, except under circumstances in the following paragraph. Testing standards shall comply with Federal Law 40 CFR 136.
In case the analyses performed by the industry and the Village results in substantially different values, and effort shall be made by the industry to collect samples at the same time the Village collects its own samples. The result of the analyses on the samples collected by the Village and the industry shall be computed using the same testing procedure as outlined in the latest edition of “Standard Methods” and the differences negotiated.
