In determining the amount of a user's discharge for purposes of industrial cost recovery, the grantee may exclude domestic wastes or discharges from sanitary conveniences. After applying the sanitary waste exclusion, dischargers in the above divisions that have a volume exceeding 25,000 GPD or the weight of biochemical oxygen demand (BOD) or suspended solids (SS) equivalent to that weight found in 25,000 GPD of sanitary waste are considered industrial users. Sanitary wastes, for purposes of this calculation of equivalency, are the wastes discharged from residential users. Any nongovernmental user of a publicly owned wastewater works which discharges wastewater to the wastewater works which contains toxic pollutants or poisonous solids, liquids or gases in sufficient quantity, either singly or by interaction with other wastes, to contaminate the sludge of any municipal systems, to injure or to interfere with any sewage treatment process, which constitutes a hazard to humans or animals, creates a public nuisance, creates any hazard in or has an adverse effect on the waters receiving any discharge from the treatment works shall be an industrial user, even if it does not discharge the equivalent of 25,000 gallons per day of sanitary wastes.
Industrial waste means any waterborne solids, liquids or gaseous wastes other than domestic wastewater, resulting from discharging from, flowing from or escaping from any commercial, industrial, manufacturing or food processing operation or process or from the development of any natural resource, or any mixture of these with water or domestic wastewater.
Intercepting sewer means a sewer constructed to receive the dry weather flow of untreated or inadequately treated sewage from one or more existing sanitary sewer system terminals other than from a dwelling or building that presently discharges or formerly discharged flow directly into any waters of the state, and convey the flow to a treatment works, or is to serve in lieu of an existing or proposed treatment works.
Natural outlet means any outlet into a watercourse, pond, ditch, lake or other body of surface water or groundwater.
Normal sewage means sanitary sewage in which BOD, suspended solids, or phosphorus concentrations do not exceed normal concentrations of:
(1)
A five-day, 20 degree Celsius, BOD of not more than 200 parts per million;
(2)
A suspended solids content of not more than 250 parts per million; or
(3)
Phosphorus not more than 12 parts per million.
Operation and maintenance cost means the actual sums spent by the utility in the operation and maintenance of its wastewater works consisting of, but not limited to, each and all of the following purposes:
(1)

(2)
Electrical power.
(3)
Chemicals, fuel and other operating supplies.
(4)
Repairs to and maintenance of the equipment associated therewith.
(5)
Premiums for hazard insurance.
(6)
Premiums for insurance providing coverage against liability for the injury to persons and/or property.
(7)
Rents and leasing costs.
(8)
Operation, licensing and maintenance costs for trucks and heavy equipment.
(9)
Consultant and legal fees.
(10)
Replacement.
Person means any and all persons, natural or artificial, including any individual, firm, company, municipal or private corporation. association, governmental agency or other entity and agents, servants or employees.
pH means the logarithm (base 10) of the reciprocal of the hydrogen ion concentration expressed in moles per liter. It shall be determined by one of the procedures outlined in the Standard Methods.
Public sewer means a sewer in which all owners or abutting properties have equal rights and which is controlled or owned by public authority.
Replacement means expenditures for obtaining and installing equipment, accessories and appurtenances which are necessary during the useful life of the treatment works to maintain the capacity and performance for which such works were designed and constructed.
Residential equivalency charge means a charge levied on users for debt retirement. The charge shall be based on the total debt retirement divided by the number of existing resident equivalent connections (REC).
Residential equivalent connection means the amount of sewage contributed to the system from a single-family residence, based on the following criteria which will be recomputed each year:
Flow = Amount of water used by single-family units
total number single-family units
BOD = 200 mg/l
55 = 250 mg/l
Sanitary sewer means a sewer that conveys domestic wastewater or industrial waste or a combination of both, and into which stormwater, surface water and groundwater or unpolluted industrial wastewater are not intentionally passed.

Quantitative determination of suspended solids shall be made in accordance with procedures set forth in Standard Methods.
