(3) Any water or waste containing suspended solids in excess of 300 milligrams per liter, except as provided for herein.
(4) Any water containing toxic or poisonous solids, liquids or gases in sufficient quantity, which, either singly or by interaction with other wastes, injure or interfere with any waste treatment process, constitute a hazard to humans or animals, create a public nuisance or create any hazard in the receiving waters of the wastewater treatment plant effluent.
(5) Any water or waste having a pH lower than 6.0 or greater than 9.0 or having any other corrosive property capable of causing damage or hazard to structures, equipment or personnel of the wastewater facilities or the sanitary sewers.
(6) Any solid or viscous substances in quantities or of such size capable of causing obstruction to the flow in sanitary sewers, or other interference with the proper operation of the wastewater facilities such as, but not limited to, gravel, ashes, bones, red dog, sand, mud, coal, straw, shavings, metal, glass, rags, feathers, tar, plastics, wood, unground garbage, whole blood, paunch manure, hair and fleshings, entrails, and paper dishes, cups, milk containers, etc., either whole or ground by garbage grinders.
(c) The following described substances, materials, waters or wastes shall be limited in discharges to the sewer system, to concentrations or quantities which will not harm either the sanitary sewers or wastewater facilities; will not have an adverse effect on the receiving stream; or will not otherwise endanger lives, limb or public property or constitute a nuisance. The limitations or restrictions on materials or characteristics of waste or wastewater discharged to the sewer system which shall not be exceeded by any person without approval of the Sanitary Board are as follows:
(1) Wastewater having a temperature higher than 40o C.
(2) Wastewater containing more than twenty-five milligrams per liter of petroleum oil, nonbiodegradable cutting oils or products of mineral oil origin.
(3) Wastewater containing floatable oils, fat or grease in excess of 500 milligrams per liter.
(4) Any garbage that has not been properly shredded with no particle greater than one-half inch in any dimension. Garbage grinders may be connected to sanitary sewers only from homes, hotels, institutions, restaurants, hospitals or similar places where garbage originates from the preparation of food in on-site kitchens for the purpose of consumption on the premises.
(5) Any water or waste containing iron, chromium, copper, zinc, mercury and similar objectionable or toxic substances to such degree that any such material discharge exceeds the limits established by the Board for such materials.
(6) Any water or waste containing color-producing or odor-producing substances exceeding limits which maybe established by the governing body.
(7) Any radioactive wastes or isotopes of such half-life concentration as may exceed limits established by the Board in compliance with applicable State or Federal regulations.
(8) Quantities of flow, concentrations or both which constitute a "sludge" as defined herein.
(9) Water or waste containing substances such as synthetic detergents which are not amenable to treatment or reduction by the wastewater facilities employed, or amenable to treatment only to such degree that the wastewater facilities effluent cannot meet the requirements of other agencies having jurisdiction over discharge to the receiving waters.
(d) The following is applicable for all new and existing food service establishments discharging fats, oils and grease into the sanitary sewer system. Grease, oil and sand separators shall be provided by the entity causing the discharge when, in the opinion of the Board, they are necessary for the proper handling of liquid wastes containing floatable grease in excessive amounts as specified in subsection (c), or any flammable wastes, sand or other harmful ingredients. All interceptors shall be of a type and capacity approved by the Board and shall be located as to be readily and easily accessible for inspection and cleaning. Such interceptors shall be inspected, cleaned and maintained as needed by the respective entity at their expense. The Board shall require any restaurant, café, fast food chain, cafeteria, or other business discharging grease or kitchen waste into the sewer system which would interfere or be incompatible with the waste treatment works to install grease traps/interceptors. Such interceptors shall not be required for private living quarters or dwelling units. Failure to comply with this policy shall be considered a violation of this Sewer Use Article and will be subject to applicable penalties, fines or discontinuance of water and sewer service.
(1) Grease and oil interceptors shall be constructed of impervious materials capable of withstanding abrupt and extreme changes in temperature. They shall be of substantial construction, watertight and equipped with easily removable covers, which, when bolted in place, shall be gastight and watertight. Where installed, all grease, oil and sand interceptors shall be maintained by the owner, at his expense, in continuously efficient operation at all times.
(2) Any food service establishment, whose grease trap discharge is found to contain floating oil and grease, may be required by the Board to sample and test their grease trap discharge. The owner shall furnish a copy of the test results to the Board for evaluation. All measurements, tests, and analysis referred to in this article 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. The cost of sampling and analysis shall be at the expense of the owner. If the results of the analysis indicate an oil or grease concentration in excess of 500 mg/l, the Board will issue the owner a notice of violation.
(3) All grease traps/interceptors shall be designed, installed and located in accordance with the West Virginia State Plumbing Code, International Plumbing Code, and the West Virginia Bureau of Public Health.
(4) The plans, specifications and operating procedures shall be submitted to the Board for review and comment. The Board will review the plans within sixty days and recommend any revisions or additions. The owner shall secure all necessary building, plumbing permits, etc. required by the Board or state agencies. The user shall construct or install the system within the time limit provided by the Board. Upon completion of construction the owner shall provide the Board with “As-Built” drawings.
(5) All construction and/or installation must be accomplished utilizing properly licensed plumbing/utility contractors.
(6) All existing food service establishments shall have grease traps/interceptors approved by the Board. Food service establishments without these facilities will be given a compliance deadline not to exceed ninety days from the date of notification.
(7) New food service establishments shall be required to install below ground grease interceptors that are sized to provide adequate grease retention capacity. Sizing will be determined in accordance with applicable plumbing codes and EPA guidelines. If new or existing facilities are limited by space or other constraints and cannot feasibly install a typical below ground interceptor, an “under-the-counter” grease interceptor may be installed with the Board’s approval. Sizing will be determined in accordance with UPA and local guidelines.
(8) Wastewater from dishwashers, garbage grinders and toilet facilities should not be discharged to grease traps/interceptors.
(9) Owners will ensure that each grease trap/interceptor is serviced frequently so that there is not overflow into the sewer system, ground or waters of the state. Servicing will be determined when the discharge is determined to be at or above discharge limits, approximately thirty-three percent (33%) of the retention capacity.
(10) The only acceptable method of cleaning the grease trap/interceptor shall be to pump out the grease for disposal by a licensed waste disposal firm. The use of chemicals, solvents, etc. in lieu of physical cleaning is prohibited.
(11) The owner will be required to maintain an inspection/service log. The log should include daily maintenance, disposal, contracts and inspections. The log shall be posted in a conspicuous location in each establishment and be made available for review. The owner will also be required to maintain records a minimum of two years.
(12) Facilities will be periodically inspected by the Board. Any deficiencies will be noted and provided to the owner, along with a schedule for compliance. Additional inspections to ensure compliance will be at the owner’s expense or as determined by the Board. Receipt of a second notice of deficiency for the same violation will result in a fine as determined by the Board in addition to any costs incurred as a result of the deficiency. Examples of additional costs would include but are not limited to, pumping, disposal of grease, sewer line and manhole cleaning, etc.
(13) Deficiencies/violations include but are not limited to: failure to install an approved grease trap/interceptor, unauthorized discharges or waste which is allowed to spill, overflow, or be discharged onto public or private property, removal or disposal of waste from a facility by a nonlicensed waste disposal firm, etc.
(e) No statement contained in this article shall be construed as preventing any special agreement or arrangement between the governing body and any industrial concern whereby an industrial waste of unusual strength or character may be accepted by the Village for treatment.
