This category shall also refer to any user of the publicly-owned treatment works identified in the Standard Industrial Classification Manual, 1987, under divisions A, B, D, E, or I, excluding those users already identified in one of the other user classes. A user may also be excluded from the INDUSTRIAL USER class if it is determined that such user will discharge only segregated domestic wastes or wastes from sanitary conveniences.

(5) RESIDENTIAL USER. An individual home or dwelling unit including mobile homes, apartments, condominiums, or multi-family dwellings that discharge only segregated domestic wastes or wastes from sanitary conveniences.
COMBINED SEWER. A sewer receiving both surface runoff and sewage.
COMPATIBLE POLLUTANT. Biochemical oxygen demand, suspended solids, pH, and fecal coliform bacteria, plus any additional pollutants identified in the NPDES permit if the treatment works was designed to treat such pollutants, and in fact can remove such pollutants to a substantial degree. The term SUBSTANTIAL DEGREE generally means removals in the order of 80% or greater.
GARBAGE. Solid wastes from the domestic and commercial preparation, cooking, and dispensing of food, and from the handling, storage, and sale of produce.
INCOMPATIBLE POLLUTANT. Any pollutant that is not a compatible pollutant, as defined in “compatible pollutant” above.
INDUSTRIAL COST RECOVERY. The recovery from each industrial user, as defined, a portion of the U.S. Environmental Protection Agency grant which is allocable to the construction of facilities for the treatment of wastes from said industries.
INFILTRATION. Any waters entering the system from the ground, through such means as, but not limited to, defective pipes, pipe joints, connections, or manhole walls. INFILTRATION does not include and is distinguished from inflow.
INFILTRATION/INFLOW. The total quantity of water from both infiltration and inflow.
INFLOW. Any waters entering the system through such sources as, but not limited to, building downspouts, footing or yard drains, cooling water discharges, seepage lines from springs, and swampy areas and storm drain cross connections.
INSPECTOR. Any person or persons authorized by the village or the Authority to inspect and approve the installation of building sewers and their connection to the public sewer system.
MAJOR CONTRIBUTING INDUSTRY. An industrial user, as defined, that discharges: a flow of 50,000 gallons or more per average work day; a flow exceeding 5% of the total treatment plant flow; toxic pollutants in toxic amounts as defined in the NPDES permit; or a flow with a significant impact on the treatment plant when considered alone or in combination with other industrial users.
MANAGER. The manager of the Harbor Springs Area Sewage Disposal Authority, or his or her authorized deputy, agent, or representative.

NPDES PERMIT. The permit issued pursuant to the National Pollution Discharge Elimination System for the discharge of wastewaters into the waters of the state.
OPERATION AND MAINTENANCE COSTS. All costs, direct and indirect, (other than debt service) necessary to ensure adequate wastewater treatment on a continuing basis, conform with all related federal, state, and local requirements, and assure optimal long-term facility management. (These O AND M COSTS include depreciation and replacement costs.)
PERSON. Any individual, firm, company, association, society, corporation, or group.
pH. The logarithm of the reciprocal of the concentration of hydrogen ions in grams per liter of solution.
PRETREATMENT. The treatment of extra strength industrial wastewater flows in privately-owned PRETREATMENT facilities prior to discharge into the public sewer.
PROPERLY SHREDDED GARBAGE. The wastes from the preparation, cooking, and dispensing of food that have 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 dimension.
PUBLIC SEWER. A sewer in which all owners of abutting properties have equal rights, and is jointly controlled by the village and Authority.
REPLACEMENT. Necessary expenditures made during the service life of the treatment works to replace equipment and plant appurtenances required to maintain the intended performance of the treatment works.

A combination of the liquid and water-carried wastes from residences, commercial buildings, institutions, and industrial establishments, (including polluted cooling water) together with such ground, surface, and stormwater as may be present. The three most common types of SEWAGE are as follows.
(1) COMBINED SEWAGE. Wastes including sanitary sewage, industrial sewage, stormwater, infiltration, and inflow carried to the wastewater treatment facilities by a combined sewer.
(2) INDUSTRIAL SEWAGE. A combination of liquid and water-carried wastes, discharged from any industrial establishment, and resulting from any trade or process carried on in that establishment. (This shall include the wastes from pretreatment facilities and polluted cooling water.)
