into a watercourse, pond, ditch, lake, or other body of surface water
or groundwater.
NITROGEN
Kjeldahl nitrogen which is the sum of organic nitrogen and
ammonia nitrogen.
NONCONTACT COOLING WATER
Water used for cooling which does not come into contact with
any raw material, intermediate or finished product, or waste and has
been used in heat exchangers, air or refrigeration compressors, or
other cooling means where contamination with process waste is not
normally expected.
NORMAL DOMESTIC STRENGTH WASTEWATER
Wastewater with concentrations of BOD no greater than 300
mg/l, suspended solids no greater than 250 mg/l, nitrogen no greater
than 45 mg/l, and phosphorus no greater than 7.0 mg/l.
OPERATION AND MAINTENANCE COSTS
All costs associated with the operation and maintenance of
the wastewater treatment facilities, including administration and
replacement costs, all as determined from time to time by the municipality.
PERSON
Any and all persons, including any individual, firm, company,
municipal or private corporation, association, society, institution,
enterprise, governmental agency, or other entity.
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 seven and
a hydrogen-ion concentration of 10.
PHOSPHORUS
The total phosphorus and is expressed in mg/l of P (phosphorus).
PRETREATMENT
The treatment of wastewater to remove or reduce the quantity
of one or more pollutants prior to discharge to publicly owned wastewater
collection or treatment facilities.
PUBLIC NUISANCE
The doing of or the failure to do something that injuriously
