Unless the context specifically indicates otherwise, the meaning of terms used in these rules and regulations shall be as follows:
BOD (denoting "biochemical oxygen demand")The quantity of oxygen utilized in the biochemical oxidation of organic matter under standard laboratory procedure in five days at 20° C. (68° F.), expressed in milligrams per liter (mg/l). Measurement shall be as set forth in the latest edition of Standard Methods for the Examination of Water and Waste Water.
CHLORINE DEMANDThe difference between the amount of chlorine added to water, sewage or industrial wastes and the amount of residual chlorine remaining at the end of a twenty-minute contact period at room temperature.
CITYThe City of Cohoes and the lands contained therein.
CITY COUNCILThe legally constituted Common Council of the City of Cohoes.

COMMISSIONThe Board of Commissioners appointed by the County Legislature to the Albany County Sewer District.
COOLING WATERThe water discharged from any system of condensation, air conditioning, cooling, refrigeration or other sources. It shall contain no polluting substances which would produce BOD or suspended solids in excess of 10 parts per million by weight or toxic substances as limited elsewhere herein.
COUNTY SEWER DISTRICTAny county sanitary sewer district as created, altered or modified by action of the Albany County Legislature.

NATURAL OUTLETAny outlet into a watercourse, pond, ditch, lake or other body of surface or ground water.
NORMAL SEWAGESewage, industrial wastes or other wastes which, when analyzed, show by weight the following characteristics:
(1) BOD of 2,000 pounds per million gallons (240 milligrams per liter) or less.
(2) Chlorine demand of 208 pounds per million gallons (25 milligrams per liter) or less.
(3) Suspended solids 2,500 pounds per million gallons (300 milligrams per liter) or less.
OTHER WASTESGarbage (shredded or unshredded), refuse, wood, egg shells, coffee grounds, sawdust, shavings, bark, sand, lime, cinder, ashes and all other discarded matter not normally present in sewage or industrial wastes.
PERSONAny individual, firm, company, association, society, corporation or group contributing directly or indirectly to the City sewer system.
pHThe negative logarithm of the hydrogen ion concentration in moles per liter. It indicates the intensity of acidity and alkalinity of the pH scale running from 0.0 to 14.0. A pH value of 7.0, the midpoint of the scale, represents neutrality. Values above 7.0 represent alkaline conditions, and those below 7.0 represent acid conditions.
PROPERLY SHREDDED GARBAGEGarbage that has been shredded to such a degree that all particles will be carried freely under the flow conditions normally prevailing in the public sewer to which it is discharged, with no particle having a dimension greater than 1/2 inch in any dimension.
RECEIVING WATERSA natural watercourse or body of water into which treated or untreated sewage is discharged.
SANITARY SEWAGESewage discharging from the sanitary conveniences of dwellings (including apartment houses and hotels), office buildings, factories or institutions and free from stormwater, surface water, industrial wastes and other wastes.
SANITARY SEWERA sewer which carries sewage and to which storm-, surface and ground waters are not intentionally admitted.
SEWAGEA combination of the water-carried wastes from residences, business buildings, institutions and industrial establishments, together with such ground-, surface and storm water as may be inadvertently present. The admixture of sewage as above defined with industrial wastes or other wastes also shall be considered sewage within the meaning of this definition.
SEWAGE SURCHARGEThe demand payment for the use of the county sewerage system for handling any sewage, industrial wastes or other wastes accepted for admission thereto in which the characteristics thereof exceed the maximum values of such characteristics in normal sewage.
SEWERA pipe or conduit for carrying sewage.
SLUGAny discharge of water, sewage or industrial waste which, in concentration of any given constituent or in quantity of flow, exceeds for any period of duration longer than 15 minutes, more than 5 times the average twenty-four-hour concentration or flow during normal operation.
STORM SEWER (STORM DRAIN)A sewer which carries stormwaters and surface waters and drainage, but excludes sewage and industrial wastes other than cooling waters and other unpolluted waters.
SUSPENDED SOLIDSSolids that either float on the surface of or are in suspension in water, sewage or other liquids and which are removable by flotation, skimming and sedimentation. Measurement shall be as set forth in the latest edition of Standard Methods for the Examination of Water and Waste Water.
TOXIC SUBSTANCESAny substance, whether gaseous, liquid or solid, which, when discharged to a public sewer in sufficient quantities, may be hazardous to sewer district personnel, tend to interfere with any biological sewage treatment process or to constitute a hazard to human beings or animals or to inhibit aquatic life or to create a hazard to recreation in the receiving waters of the effluent from a sewage treatment plant.
