(a) "Biochemical Oxygen Demand" (or BOD) of sewage, sewage effluent, polluted waters or industrial wastes means the quantity of dissolved oxygen in milligrams per liter required during stabilization of the decomposable organic matter by aerobic biochemical action under standard laboratory procedures for five days at 20o centigrade. The laboratory determinations shall be made in accordance with procedures set forth in "Standard Methods".

(m) "Natural outlet" means an outlet, including storm sewers and combined sewer overflows, into a watercourse, pond, ditch, lake, or other body of surface or groundwater.
(n) "NPDES (National Pollutant Discharge Elimination System) Permit" means the same as such is defined in the Code of Federal Regulations, 40 CFR Part 125, and in The Clean Water Act, Section 402.
NPDES Permit B619*AD, governing the Lewisburg Treatment Plant discharge, is currently pending revision by OEPA with proposed discharge limits as follows:
Discharge Limitations | ||
Parameter | Summer | Winter |
BOD5 | 20 mg/1 | 30 mg/1 |
Suspended Solids | 20 mg/l | 30 mg/l |
Fecal Coliform | 1,000/100 ml | N/A |
NH3-N | 5 mg/1 | monitor only |
pH | 6.5-9.0 S.U. | 6.5-9.0 S. U. |
Chlorine | 0.02 mg/1 | N/A |
Dissolved Oxygen | 6.0 mg/l | monitor only |
(o) "Nonsanitary flow" means storm water originating from downspouts, storm and groundwater drains, and foundation drains.
(p) "Normal domestic sewage" means wastewater which does not exceed a biochemical oxygen demand strength of 250 milligrams per liter of fluid, or a suspended solids strength in excess of 250 milligrams per liter of fluid.
(q) "Person" means any individual, firm, company, association, society, corporation or group.
(r) "Public sewer" means any sewer owned by the Village, including storm, sanitary, or combined sewers.
(s) "Residential" means a principal family residence or habitation classified as a single family, multifamily, or apartment dwelling that discharges domestic sanitary wastewater into the public wastewater treatment system, works, and facility.
(t) "Sanitary sewer" means a sewer which carries sanitary and industrial wastes, and to which storm, surface, and groundwater are not intentionally admitted.
(u) "Sewage" means the combination of the liquid and water-carried wastes from residences, commercial buildings, industrial plants, and institutions (including polluted cooling water).
(v) "Sewage systems" means the structures, equipment, and process required to collect, transport, and treat domestic and industrial wastes and dispose of the effluent and accumulated residual solids and shall be synonymous with "wastewater treatment".
(w) "Storm sewer" means a pipe or conduit designed for the purpose of carrying storm, surface, cooling, and drainage water from the point of origin to some point of disposal, but which is not intended to carry domestic or industrial sewage.
(x) "Shall" is mandatory; "may" is permissive.
(y) "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 hours concentration of flows during normal operation.
(z) "Suspended solids" means solids which either float on the surface of or are in suspension in water, sewage or other liquid and which are removable by laboratory filtration. Their concentration shall be expressed in milligrams per liter. Quantitative determinations shall be made in accordance with procedures set forth in "Standard Methods".
(aa) "User" means any person who discharges, causes, or permits the discharge of wastewater into the wastewater treatment system.
(bb) "Wastewater" means the liquid and water-carried waste from dwellings, commercial buildings, industrial facilities, and institutions, together with any groundwater, surface water, or storm water that may be present, whether treated or untreated, which is discharged or permitted to enter the wastewater treatment system.
(cc) "Wastewater Treatment System" means the structures, equipment, and process required to collect, transport, and treat domestic and industrial wastes and dispose of the effluent and accumulated residual solids and shall be synonymous with "sewage system".
