A. Has a flow of 50,000 gallons or more per average work day;
B. Has a flow greater than five percent of the flow carried by the municipal system receiving the waste;
C. Has in its waste, a toxic pollutant in toxic amounts as defined in standards issued under Section 307(a) of the Federal Act; or
D. Is found by the permit issuance authority in connection with the issuance of an NPDES permit to the publicly owned wastewater treatment works receiving the waste, to have significant impact, either singly or in combination with other contributing industries, on that wastewater treatment works or upon the quality of effluent from that works.
(15) "May" is permissive; "shall" is mandatory.
(16) "Natural outlet" means any outlet, including storm sewers and combined sewer overflows into a watercourse, pond, ditch, lake or other body of surface or groundwater.
(17) "NPDES permit" means the National Pollutant Discharge Elimination System permit.
(18) "Owner" or "person" means any individual, firm, company, association, society, corporation or group.
(19) "pH" means the reciprocal of the logarithm of the hydrogen ion concentration. The concentration is the weight of hydrogen ions, in grams per liter of solution. Neutral water, for example has a pH value of 7 and a hydrogen ion concentration of 10.07.
(20) "Pollutant" means dredged soil, solid waste, incinerator residue, wastewater, garbage, wastewater sludge, munition, wrecked or discarded equipment, rock, sand, cellar dirt and industrial, municipal and agricultural waste discharged into water.
(21) "Pretreatment" means the treatment of wastewaters from sources before introduction into the wastewater treatment works.
(22) "Properly shredded garbage" means the wastes from the preparation, cooking and dispensing of food that has been shredded to such a degree that all particles will be carried freely under the flow conditions normally prevailing in public sewers, with no particle greater than one-half inch in any dimension.
(Ord. 1976-18. Passed 10-18-76.)
(23) “Public sewer” means a common sewer controlled by a governmental agency or public utility. Includes any wye, tee, riser, or crossover, but does not include any connections/connection joints to a building sewer.
(Ord. 2009-12. Passed 9-21-09.)
(24) "Sanitary sewage" means wastewater contributed by reason of human occupancy.
(25) "Sanitary sewer" means a sewer that carries liquid and water-carried wastes from residences, commercial buildings, industrial plants and institutions, together with minor quantities of ground, storm and surface waters that are not admitted intentionally.
(26) "Sewer" means a pipe or conduit for carrying wastewater or storm water.
(27) "Sewer contractor" means the agent of the owner responsible for the construction of the building sewer.
(28) "Slug" means any discharge of water or wastewater which, in concentration of any given constituent or in quantity of flow, exceeds for any period of duration longer than fifteen minutes more than five times the average twenty-four hour concentration or flow during normal operation and will adversely affect the wastewater treatment works.
(29) "Storm sewer" or "storm drain" means a sewer or drain for conveying water, groundwater, subsurface water or unpolluted water from any source.
(Ord. 1976-18. Passed 10-18-76.)
