As used in this Division, the following terms shall have the
meanings indicated:
- Biochemical oxygen demand (BOD)
- is the amount of oxygen required by bacteria while stabilizing
decomposable organic matter under aerobic conditions for five days.
The determination of "BOD" shall be performed in accordance with the
procedures prescribed in the latest edition of Standard Methods for
the Examination of Water and Wastewater, published by the American
Health Association.
- Building
- includes each individual residential unit in a multifamily
housing complex.
- Building drain
- means that part of the lowest horizontal piping of a building's
plumbing which receives the discharge from soil, waste and other drainage
pipes inside the walls of the building and conveys it to the building
sewer, beginning five feet (1.5 meters) outside of the inner face
of the building wall.
- Building sewer
- means the extension from the building drain to the public
sewer or other place of disposal; it may also be called a "house connection."
- Categorical Standards
- shall be the National Categorical Pretreatment Standards
or Pretreatment Standards.
- Compatible pollutant
- is biochemical oxygen demand, suspended solids, pH and fecal
coliform bacteria, plus any additional pollutants identified in the
water pollution control facility's NPDES permit, where the water pollution
control facility is designed to treat such pollutants and, in fact,
does treat such pollutants to the degree required by the NPDES permit.
- Composite sample
- means a mixture of aliquot samples obtained at regular intervals
over a time period. The volume of each aliquot is proportional to
the discharge flow rate for the sampling interval. The minimum time
period for composite sampling shall be four hours.
- Cooling water
- means process water in general used for cooling purposes
to which the only pollutant added is heat and which has such characteristics
that it may be discharged to a natural outlet in accordance with federal
and state laws and regulations.
- Domestic sewage
- means sewage that consists of water and human excretions
or other waterborne wastes incidental to the occupancy of a residential
building or nonresidential building but not wastewater from water-softening
equipment, commercial laundry, wastewater and blowdown from heating
and cooling equipment.
- Floatable oil
- is oil, fat or grease in a physical state that it will separate
by gravity from sewage by treatment in an approved pretreatment facility.
- Garbage
- means the animal or vegetable waste resulting from the handling,
preparation, cooking or serving of foods.
- Grab sample
- is a sample which is taken from a waste stream on a one-time
basis, with no regard to the flow in the waste stream and without
consideration of time.
- Holding tank waste
- is any waste from holding tanks, such as vessels, chemical
toilets, campers, trailers and septage-hauling trucks.
- Incompatible pollutant
- is all pollutants other than "compatible pollutants," as
defined in this section.
- Industrial wastewater
- means all wastewater from industrial process, trade or business
and is distinct from domestic sewage.
- National Pollution Discharge Elimination System (NPDES)
permit
- is a permit issued pursuant to Section 402 of the Federal
Water Pollution Control Act, also known as the "Clean Water Act" (33
U.S.C. § 1342).
- Oil
- means oil which is of either mineral or vegetable origin
and disperses in water or sewage at temperatures between zero degrees
and sixty-five degrees Celsius (0° and 65° C.). For the purposes
of this Article, emulsified oil shall be considered as soluble "oil."
- Person
- is any individual, partnership, copartnership, firm, company,
corporation, association, joint-stock company, trust, estate, governmental
entity or any other legal entity, or their legal representatives,
agents or assigns. The masculine gender shall include the feminine
and the singular shall include the plural, where indicated by the
context.
- pH
- means the logarithm of the reciprocal of the hydrogen-ion
concentrations. The concentration is the weight of hydrogen ions,
in grams, per liter of solution.
- Pretreatment or treatment
- is the reduction of the amount of pollutants, the elimination
of pollutants or the alteration of the nature of pollutant properties
in wastewater to a less harmful state prior to or in lieu of discharging
or otherwise introducing such pollutants into a water pollution control
facility. The reduction or alteration can be obtained by physical,
chemical or biological processes, except as prohibited by Title 40,
Code of Federal Regulations, Section 403.6(d).
- Properly shredded garbage
- shall mean 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 1/2 inch (1.27 centimeters)
in any dimension.
- Public sewer
- shall mean a common sanitary sewer controlled by a governmental
agency or public utility.
- Sanitary sewer
- means a sewer which collects and conveys domestic sewage
from residences, public buildings, commercial establishments, industries
and institutions. A sanitary sewer may also collect and convey permitted
industrial wastewater and unintentionally admitted ground-, storm-
and surface waters.
- Septage
- means the liquids and solids which are removed from a tank
used to treat domestic sewage.
- Sewage
- means human and animal excretions and all domestic and such
manufacturing wastes as may tend to be detrimental to the public health.
- Sewage collection system
- means the structures and equipment required to collect and
convey sewage to the water pollution control facility.
- Slug
- means any sudden or excessive discharge which exceeds permitted
levels either in terms of pollutant concentration or instantaneous
flow rate in such a manner as to adversely affect the sewage collection
system and/or the water pollution control facility.
- Storm sewer
- means a sewer which collects and conveys stormwater or groundwater.
- Suspended solids
- means the solid matter, measured in milligrams per liter,
which may be in suspension, floatable or settlable and removable by
laboratory filtering as prescribed in the latest edition of Standard
Methods for Examination of Water and Wastewater.
- Toxic pollutant
- is any pollutant or combination of pollutants listed as toxic
in regulations promulgated by the Administrator of the Environmental
Protection Agency under the provisions of Section 307(a) of the Federal
Water Pollution Control Acts or other Acts.
- User
- is any person who contributes, causes or permits the contribution
of sewage into the sewer system.
- Watercourse
- means a natural or artificial channel for the passage of
water, either continuously or intermittently.
- Water Pollution Control Facility (WPCF)
- means an arrangement of devices for the treatment of sewage
and sludge.
