All measurements, tests and analyses of the characteristics of waters and wastes to which reference is made in this regulation shall be determined in accordance with the latest edition of Standard Methods for the Examination of Water and Wastewater, published by the American Public Health Association. Sampling methods, location, times, durations and frequencies are to be determined on an individual basis, subject to approval by the Authority. Sampling shall be carried out by customarily accepted methods to reflect the effect of constituents upon the sewage works and to determine the existence of hazards to life, limb and property. (The particular analyses involved will determine whether a twenty-four-hour composite of all outfalls of a premises is appropriate or whether a grab sample or samples should be taken. Normally, but not always, BOD and suspended solids analyses are obtained from twenty-four-hour composites of all outfalls, whereas pH's are determined from periodic grab samples.)
B. 
All industries discharging into a public sewer shall perform such monitoring of their discharge as the Authority and/or Town Engineer and/or duly authorized employees of the Town may reasonably require, including installation, use and maintenance of monitoring equipment, keeping records and reporting the results of such monitoring to the Authority. These records shall be made available upon request to the DEP. Such monitoring shall be performed pursuant to Section 22a-430 of the Connecticut General Statutes, as amended.
No statement contained in this article shall be construed as preventing any special agreement or arrangement between the Authority and any industrial concern whereby an industrial waste of unusual strength or character may be accepted by the Authority for treatment, provided that such agreements do not contravene any requirements of existing federal and state laws and are compatible with any user charge in effect.
A. 
Any new discharge from a single source to the sewer system of domestic sewage (or industrial) wastewaters in excess of 5,000 gallons per day shall not be authorized without the discharger first obtaining a permit from the Authority and/or any other authority as may be required in order to comply with any local, state and federal ordinances, codes and laws that may apply. In addition, a state permit is required for industrial discharges of any quantity for community systems as defined in Section 7-245 of the Connecticut General Statutes and for domestic discharges in excess of 1% of the design flow of the treatment plant or 50,000 gallons per day, whichever is less.
B. 
Any person proposing a new discharge of industrial wastes into the system or a substantial change in the volume or character of industrial pollutants that are being discharged into the system shall notify the Authority at least 60 days prior to the proposed change in order to notify the Town of Vernon with appropriate documentation.
A. 
The admission into the public sewers of any waters or wastes having a five-day BOD greater than 300 milligrams per liter by weight; or containing more than 350 milligrams per liter by weight of suspended solids, or containing any quantity of substances having the characteristics described in § 164-5D; or having a chlorine demand of more than 15 milligrams per liter by weight; or having an average daily flow greater than 2% of the average daily sewage flow of the Town shall be subject to the review and approval of the Authority.
B. 
Where necessary, in the opinion of the Authority, the Owner shall provide, at his expense, such preliminary treatment as may be necessary to reduce the BOD to 300 milligrams per liter, the suspended solids to 350 milligrams per liter by weight and the chlorine demand to 15 milligrams per liter by weight; or reduce objectionable characteristics or constituents to within the maximum limits provided for in § 164-5D; or control the quantities and rates of discharge of such waters or wastes. Plans, specifications and any other pertinent information relating to proposed preliminary treatment facilities shall be submitted for the approval of the Authority and of any or all state regulatory agencies having jurisdiction, and no construction of such facilities shall be commenced until said approvals are obtained in writing.
In determining whether any waste discharged or proposed to be discharged into any public sewer is to be excluded, consideration will be given to the quantity, time or times, rate and manner of discharge, dilution and character of the waste in question, the size of the sewer or other wastes likely in said sewer and other pertinent facts. Minute quantities of a waste which would be objectionable in larger quantities may be accepted if sufficiently diluted and when and as discharged or if the quantity discharged is small as compared with the flow in the receiving sewer, but any permission to discharge minute quantities of an otherwise excluded waste shall be revocable at any time by the Authority and/or Town Engineer and/or duly authorized employees of the Town.
A. 
At all premises where waste or substances specified to be excluded from public sewers by this regulation are present and liable to be discharged directly or indirectly into said sewers, suitable and sufficient piping layouts, oil, grease, sand and flammable waste traps or separators, screens, settling tanks, diluting devices, storage or regulating chambers, treatment, cooling or other equipment and devices shall be provided. These shall be maintained and properly operated by the Owner of the premises or his agent at his expense to ensure that no waste or substance is discharged in violation of the requirements of these regulations.
B. 
Upon the promulgation of the federal categorical pretreatment standard for a particular industrial subcategory, the federal standard, if more stringent than limitations imposed under this regulation for sources in that subcategory, shall supersede the limitations imposed under this regulation.
C. 
No user shall increase the use of process water in an attempt to dilute a discharge as a partial or complete substitute for adequate treatment to achieve compliance with the limitations contained in the federal categorical pretreatment standards or in any specific pollutant limitations which may be developed by the Commissioner of the DEP.
D. 
Such facilities for pretreatment of wastes or waters discharged to public sewers shall be approved by the Authority and by any or all state regulatory agencies having jurisdiction. The Authority or state agencies may require of an Owner installing pretreatment facilities plans, specifications and a description of the facilities which are proposed. On premises where any of the wastes or substances as described in § 164-13 are present, the Authority may require the Owner to provide, operate and maintain at his (the Owner's) expense a sampling well or wells, flow-measuring devices, manholes or other appurtenances, all readily accessible, on the building sewer or drain from said premises near the point where said sewer or drain connects to the public sewer. By means of said sampling well or wells, flow-measuring devices or other appurtenances, the Owner, occupants of said premises, said Authority or any public officer having legal jurisdiction may secure samples of or examine the wastes being discharged into the public sewer for the purpose of determining compliance or noncompliance with the requirements of this regulation.
E. 
The Town Engineer or a duly authorized representative shall have the right, as a condition to the connection to and/or continued use of the Town sewer facility, to enter and inspect any part of the premises served by public sewers upon which there may be reason to believe that violations of the requirements of this regulation have occurred or are likely to occur for the purpose of ascertaining the facts as to such violation or suspected violation or of obtaining samples of wastes or of inspecting flow-measuring devices or treatment facilities provided to prevent prohibited discharges.
All measurements, tests and analyses of the characteristics of waters and wastes to which reference is made in this section shall be determined in accordance with the latest edition of Standard Methods for the Examination of Water and Sewage. 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.
Each user shall provide protection from accidental discharge of prohibited materials or other substances regulated by this regulation. Facilities to prevent accidental discharge of prohibited materials shall be provided and maintained at the Owner's expense.
A. 
Within five days following an accidental discharge, the user shall submit to the Town Engineer and the Authority a detailed written report describing the cause of the discharge and the measures to be taken by the user to prevent similar future occurrences. Such notification shall not relieve the user of any expense, loss, damage or other liability which may be incurred as a result of damage to the wastewater treatment facility, fish kills, aquatic plants or any other damage to persons or property, nor shall such notification relieve the user of any fines, civil penalties or other liability which may be imposed by this regulation or other applicable law.
B. 
A notice shall be permanently posted on the user's bulletin board or other prominent places advising employees whom to call in the event of an accidental discharge. Employers shall ensure that all employees are advised of the emergency notification procedure.
No person shall discharge or cause to be discharged into any public sewer, either directly or indirectly, any overflow or effluent from a septic tank, cesspool, subsurface drainage trench, bed or filter or other receptacle storing organic waste, except as may be permitted by the Authority.
