(A) No person shall discharge or cause to be discharged any storm water, surface water, ground water, roof runoff, foundation drainage, cooling water or unpolluted industrial process waters to any sanitary sewer.
(B) No person shall discharge or cause to be discharged to any public sewer any harmful waters or wastes, whether liquid, solid, gas, capable of causing obstruction to the flow in sewers, damage or hazard to structures, equipment and personnel of the sewage works, or other interference with the proper operation of the sewage works.
(C) Grease, oil and sand interceptors shall be provided when in the opinion of the Inspector they are necessary for the proper handling of liquid wastes containing grease in excessive amounts or any flammable wastes, sand and other harmful ingredients, except that the interceptors shall not be required for private living quarters or dwelling units. Where installed, they shall be maintained by the owner at his or her expense in continuously efficient operation at all times.
(D) (1) The admission into the public sewers of any waters or wastes having harmful or objectionable characteristics shall be subject to the review and approval of the Superintendent, who may prescribe limits on the strength and character of these waters or wastes. Users may not discharge into the sanitary sewer system any wastewater containing concentrations of pollutants greater than the following limits:
Pollutant | Limits |
Pollutant | Limits |
BOD | 250 mg/l |
Mercury | N.D.¹ |
Molybdenum | 0.11 mg/l |
Total kjeldahl nitrogen | 30 mg/l |
Oil, grease and fats | 100 mg/l |
Phosphorus | 7 mg/l |
TSS | 200 mg/l |
Polychlorinated biphenyl (PCB) | N.D.² |
In addition, users may not discharge waste water with a pH of 6.0 s.u. or less or with a pH of 9.5 s.u. or more. If a pollutant is regulated by this standard and some other standard, then the more stringent standard applies. | |
¹ Mercury sampling procedures, preservation and handling, and analytical protocol for compliance monitoring shall be in accordance with U.S. EPA method 245.1. The detection limit shall not exceed 0.2 ug/l, unless higher levels are appropriate due to matrix interference. | |
² The detection level shall not exceed 0.1 ug/l. Compliance monitoring shall be in accordance with EPA method 608. Any discharge of these substances at detectable levels is a specific violation of these regulations. | |
(2) Where necessary, in the opinion of the Superintendent, the owner shall provide at his or her expense preliminary treatment as may be necessary to treat these wastes prior to discharge to the public sewer. Plans, specifications and any other pertinent information relating to proposed preliminary treatment facilities shall be submitted for the approval of the Superintendent and of the State Board of Health and no construction of the facilities shall be commenced until approval is obtained in writing. Where preliminary facilities are provided for any waters or wastes, they shall be maintained continuously in satisfactory and effective operation by the owner at his or her expense.
(E) When required by the Superintendent, the owner of any property served by a building sewer carrying industrial wastes shall install and maintain at his or her expense a suitable control manhole in the building sewer to facilitate observation sampling and measurement of the wastes. All measurements, tests and analysis of the characteristics of waters and wastes shall be determined in accordance with Standard Methods for the Examination of Water and Sewage, and shall be determined at the control manhole or upon suitable samples taken at the control manhole. In the event that no special manhole has been required, the control manhole shall be considered to be the nearest downstream manhole in the public sewer to the point at which the building sewer is connected.
(F) In addition to requiring the industrial user to install a manhole to monitor the strength of its industrial waste pursuant to the terms of this subchapter, the industrial user may be required by the village at its sole discretion, to install at the user's expense, an approved meter to register accurately all water flowing to the system for purposes of implementing the foregoing rates and the service charges established under the terms of this subchapter. The sampling for all parameters in the above table shall be on a 24 hour flow proportional, composite basis. All sampling and testing must be based on the requirements of this subchapter in accordance with 40 C.F.R. part 136, applicable general pretreatment standards in 40 C.F.R. part 403, categorical pretreatment standards, state regulations and applicable village ordinances.
(G) Sampling frequency shall be determined by the village on a case by case basis, but not less than monthly. For each monthly period, two samples shall be collected flows less than 10,000 gallons per day and four samples shall be collected for facilities generating 10,000 gallons per day or greater. Additional sampling frequencies shall be determined by the village to assure continual compliance with this subchapter and all rules and regulations. Additional monitoring or change in frequency may be required by the village with reasonable notification in writing. All sampling and analytical costs are the responsibility of the sewer user. Samples shall be collected by the village or by the sewer user with the village's permission. The sewer analytical testing shall be performed at a state-certified lab with all test results sent to the village and to the sewer user. Sampling shall be done in a timely manner so that analytical results are available at the time the billing is performed.
(H) The sewer user must notify the village immediately upon becoming aware of any problems, through sampling or by other means, that violate village's ordinances and regulations, or of any slugs, upsets, bypasses, spills, noncompliance or any other situation that could cause problems in the sewer system. The notification must be followed within five days, with submission of a detailed written report describing the cause of the accident or bypass, its duration, the discharge limit violations, measures being taken to prevent future occurrences and dates for completion of the measures. Discharge limit violations noted through sampling and testing must be retested and results submitted within 30 days. Following any corrective action taken as result of discharge limit violations, sampling and testing will be done and results submitted to demonstrate compliance within 30 days of completion of the corrective action.
(I) All records and reports pertaining to any activities or discharges related to this subchapter and general pretreatment requirements, including report and records of problems, shall be maintained a minimum of three years by the sewer user or through any litigation periods related to the reports and records.
(J) Sampling and analysis shall be performed in accordance with techniques prescribed in 40 C.F.R. part 136 and amendments thereto. Test results must contain the time, date and place of sampling, names of laboratories and persons sampling and analyzing the material. All laboratories providing test results for any reports, shall have an active quality control and quality assurance program in operation to provide reliable and accurate test data and be state-certified. Flow must be measured and recorded for each day that samples are taken and included in the reports. Each sewer user must maintain records of average daily flow and maximum daily flow at all discharge points.
