GARBAGE. The animal and vegetable waste resulting from the handling, preparation, cooking, and serving of foods.
INDUSTRIAL WASTES. The wastewater from industrial processes, trade, or business as distinct from domestic sanitary wastes.
MAY. Permissive.
NATURAL OUTLET. Any outlet, including storm sewers, into a watercourse, pond, ditch, lake or other body of surface or groundwater.
NORMAL DOMESTIC WASTES. Sanitary wastes which do not exceed 250 mg/l BOD, 250 mg/l SS or 30 mg/l ammonia in strength; phosphorus in excess of 4 mg/l; and fats, wax grease, or oils, collectively, whether emulsified or not, in excess of 100 mg/l.

PERSON. Any individual, firm, company, association, society, corporation, or group.
pH. The logarithm of the reciprocal 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 10-7.
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 ½ inch (1.27 centimeters) in any dimension.
SANITARY SEWER. 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.
SHALL. Mandatory.
SLUG. 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 15 minutes, more than 5 times the average 24-hour concentration, or flows during normal operation, and shall adversely affect the collection system and/or performance of the wastewater treatment works.
STORM DRAIN. A drain for conveying water, groundwater, subsurface water, or unpolluted water from any source.
SUPERINTENDENT. The Superintendent of the wastewater treatment works of the Town of Monrovia, or his or her authorized deputy, agent, or representative.
