Stormwater and all other unpolluted drainage shall be discharged to such sewers as are specifically designated as storm sewers or to a natural outlet. Industrial cooling water or unpolluted process waters may be discharged to a storm sewer or natural outlet on approval of the Town and New York State Department of Environmental Conservation.
No person shall discharge or cause to be discharged any stormwater, surface water, groundwater, roof runoff, subsurface drainage, cooling water, impounded water or unpolluted industrial process waters to any sanitary sewer without written permission of the District.
Stormwater and all other unpolluted drainage shall be discharged to such sewers as are specially designated as storm sewers or to a natural outlet approved by the Town and the Department of Environmental Conservation.
Except as hereinafter provided, no persons shall discharge or cause to be discharged any of the following described waters or wastes to any public sewers:
Any liquid or vapor having a temperature lower than 32° F./0° C. or higher than 150° F./65° C.
Any water or waste which may contain more than 100 milligrams per liter by weight of fats, oils or grease.
Any gasoline, benzene, naphtha, fuel oil, waste petroleum products, mineral oil or other flammable or explosive liquids, solids or gasses.
Any garbage that has not been properly shredded.
Any ashes, cinders, sand, mud, grit, straw, offal, shavings, metal, glass, rags, feathers, entrails, tar, plastic, wood, sawdust, manure or any other solid or viscous substance capable of causing obstruction of the flow of the sewer or other interference with the proper operation of the sewage system.
Any water or waste having a pH lower than 6.0 or higher than 9.0 or having any other corrosive property capable of causing damage or hazard to structures, equipment and personnel of the sewage system, in the opinion of the District.
Any water waste containing a toxic or poisonous substance in sufficient quantity to injure or interfere with the sewage treatment process, to constitute a hazard to humans or animals or to create any hazard in the sewage system in the opinion of the District.
Any radioactive wastes or isotopes of such half-life or concentration as may exceed limits established by the District in compliance with applicable state and federal regulations.
Any water or wastes containing suspended solids of such character and quantity that unusual attention or expense is required to handle such materials at the wastewater treatment plant.
Any water or waste containing a high chlorine demand to interfere with sewage treatment process. Such toxic substance shall be limited to the average concentrations listed hereinafter in the sewage as it leaves any pretreatment facility, and at no time shall the hourly concentration exceed three times the average concentrations. If the concentrations listed are exceeded, individual establishments will be subject to control by the District in volume and concentration of waste discharges.
Any food canning waste except after approved pretreatment by the owner to remove all bulk solids and particles greater than 1/8 inch in any dimension.
Normal sanitary sewage shall be construed to fall within the following ranges at the effluent of the industrial plant in question. Permissible ranges shall be as follows:
Grease, oil and sand interceptors shall be provided when, in the opinion of the District, they are necessary for the proper handling of waste containing grease in excessive amounts or any flammable wastes, sand, grit or other harmful ingredients. All interceptors shall be of a type and capacity approved by the District and shall be located so as to be readily and easily accessible for cleaning and inspection. Grease and oil interceptors shall be constructed of impervious materials capable of withstanding extreme temperature. They shall be of substantial construction and watertight and equipped with easily removable covers which, when bolted in place, shall be gastight and watertight. Grease and oil interceptors shall be in any place or building having a capacity to serve group meals.
Where installed, all grease, oil, sand and grit interceptors shall be maintained by the owner at his expense in continuous efficient operation at all times, Materials collected shall not be reintroduced into the sewage system. The interceptors shall be readily accessible and open to inspection by the District upon request at any time.
The admission into public sewers of any waters or wastes having a five-day biochemical oxygen demand (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 substance having the characteristics described in § 279-18C(10) or having an average daily flow greater than 2% of the average daily sewage flow of the sewer system shall be subject to the review and approval of the District. Where necessary, in the opinion of the District, the owner shall provide, at his expense, such preliminary treatment as may be necessary to reduce the BOD to 300 milligrams or to reduce objectionable characteristics or constituents to within the maximum limits provided for in this section or to 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 approval of the District, together with a letter from the New York State Department of Environmental Conservation approving the proposed preliminary treatment facilities, and no construction of such facilities shall be commenced until such approvals are obtained in writing.
Where preliminary treatment facilities are required for any waters or wastes, no permit will be granted until such pretreatment units have been placed in operation and have demonstrated their effectiveness by test. The cost of such testing, sampling and analyzing shall be borne by the waste contributor. Said preliminary treatment facilities shall be maintained continuously and satisfactorily in effective operation by the owner at his expense.
When required by the District, the owner of any property served by the building sewer carrying commercial industrial wastes shall install a suitable control manhole in the building sewer to facilitate observation, sampling and measurement of the waste. Such manhole, when required, shall be conveniently and safely located. It is to be constructed in accordance with plans approved by the District. The manhole shall be installed by the owner at his expense and shall be maintained by him/her as to be safe and accessible at all times.
All measurements, tests and analyses of the characteristics of water and waste to which references are made in § 279-18C and G shall be determined in accordance with standard methods for the examination of water and sewage or with methods approved by the New York State Department of Environmental Conservation based on suitable samples taken at the control manhole provided for in § 279-18J. In the event that no special manhole has been required, the control manhole may be considered to be the nearest downstream manhole in the public sewer to the point at which the building sewer is connected. The frequency and duration of the sampling of the industrial waste shall not be less than once a quarter for 24 hours. However, more frequent and longer periods may be required at the discretion of the District. The cost of these analyses shall be borne by the owner.
No statement contained in this section shall be construed as preventing any special agreement or arrangement between the District and any industrial, commercial or domestic concern whereby waste which is of unusual strength or character can be accepted by the District for treatment subject to payment therefor by such concern.
No unauthorized person shall maliciously, willfully or negligently break, damage, destroy, uncover, deface or tamper with any structure, appurtenance or equipment which is part of the sewage works. Any person violating this provision shall be subject to immediate arrest under a charge of disorderly conduct.
