Section 2821. Definitions
A. Act
The Clean Water Act (33 U.S.C. 1251 et seq), as amended.
B. Bypass The intentional diversion of wastes from any portion of a dischargers treatment facility.
C.
Categorical (National)
Pretreatment
Standards
National Pretreatment Standards means a standard promulgated by EPA under 40 CFR Chapter I, Subchapter N, specifying quantities or concentrations of pollutant properties which may be discharged or introduced into municipally owned wastewater facilities by specific industrial discharges.
D. Cooling Water Uncontaminated (non-contact): Water used for cooling purposes only which has no direct contact with any raw material, intermediate, or final product.
Contaminated: Water used for cooling purposes only which may become contaminated either through the use of water treatment chemicals used for corrosion or biocides, or by direct contact with process materials and/or wastewater.
E.
Discharger-Industrial Discharger/User
Any non-residential user who discharges a non-domestic waste into municipally owned wastewater facilities by means of pipes, conduits, pumping stations, force mains, constructed drainage ditches, surface water intercepting ditches, intercepting ditches, and all constructed devices and appliances and in structures appurtenant thereto.
F. IndirectDischarge The discharge or the introduction of non-domestic pollutants from a source regulated under Section 307 (b) or (c) of the Act, into municipally owned wastewater facilities.
G. Industrial\Waste
Solid, liquid or gaseous waste resulting from any industrial, manufacturing, trade, or business process or from the development, recovery or processing of natural resources.
H. Interference The inhibition or disruption of a municipal sewer system, treatment processes, or operations, or sludge processes, use or disposal, and therefore is a cause of a violation of any requirements of its NPDES permit, State Waste Discharge License, or prevents sewage sludge use or disposal in accordance with State and Federal regulations.
I. NPDES National Pollutant Discharge Elimination System permit program of the US EPA.
J. O & M Operation and Maintenance.
K.
L.
Other Wastes
Pass-through Decayed wood, sawdust, shavings, bark, lime, refuse, ashes, garbage, offal, oil, tar, chemicals, and other substances except sewage and industrial wastes.
A discharge which exits the municipally owned wastewater facility into waters of the United States (as defined in 40 CFR Part 122.2), in quantities or concentrations, which alone or in conjunction with a discharge or discharges from other sources, is a cause of a violation of any requirement of the facilities State discharge license or federal NPDES permit (including an increase in the magnitude or duration of a violation).
M
Pollutant
Dredged spoil, solid waste, incinerator residue, sewage, garbage, sewage sludge, munitions, chemical wastes, biological materials, radioactive materials, heat, wrecked or discarded equipment, rock, sand, cellar dirt, and industrial, municipal and agricultural waste discharged into a municipally owned wastewater facility or its collection system.
N.
O.
P. Pretreatment
Process wastewater
Process wastewater pollutants The reduction of the amount of pollutants, the elimination of pollutants, or the alteration of the nature of pollutants in wastewater to a less harmful state prior to or in lieu of discharging or otherwise introducing such pollutants into municipally owned wastewater facility.
The reduction or alteration may be obtained by physical, chemical or biological processes, process changes or by other means, except as prohibited by 40 CFR Part 403.6(d). Appropriate pretreatment technology includes control equipment such as equalization tanks or facilities, for protection against surges or slug loadings that might interfere or otherwise be incompatible with the municipally owned wastewater facility.
Any water which, during manufacturing or processing , comes into direct contact with or results from the production or use of any raw material, intermediate product, finished product, by-product, or waste product.
Pollutants present in process wastewater.
Q. Sewage Water-carried human wastes or a combination of water-carried wastes from residences, business building, institutions and industrial establishments, together with such ground, surface, storm, or other waters as may be present.
R.
S.
T.
Shall
Significant Industrial User (SIU)
Slug
discharge Is mandatory; may is permissive
(a) all categorical industrial users and (b) any noncategorical industrial user that (i) discharges 25,000 gallons per day or more of process wastewater, (ii) contributes process waste-water which makes up five percent or more of the average dry weather hydraulic or organic capacity of the municipal treatment plant, or (iii) has a reasonable potential, in the opinion of the City to adversely affect the treatment plant operation (inhibition, pass through, sludge contamination, or endangerment of City employees).
Any discharge of a non-routine, episodic nature, including but not limited to an accidental spill or a non-customary batch discharge.
U. Slugload Any substance released in a discharge at a rate and/or concentration which causes interference to municipally owned wastewater facility.
V. Toxic Pollutants Those substances listed in 40 CFR Part 401.15.
W. Upset An exceptional incident in which a discharger unintentionally and temporarily is in a state of noncompliance with the standards set forth in their discharge permit or this Ordinance due to factors beyond the reasonable control of the discharger, and excluding noncompliance to the extent caused by operational error, improperly designed or inadequate treatment facilities, lack of preventive maintenance, or careless or improper operation thereof.
X Wastewater Industrial waste, or sewage or any other waste including that which may be combined with any ground water, surface water or storm water, that may be discharged to the municipal wastewater facilities.
Y. Wastewater
Facilities Any sewage treatment works and the sewers and conveyance appurtenances discharging thereto, owned and operated by the municipality. The definition includes any devices and systems used in the storage, treatment, recycling and reclamation of municipal sewage or industrial wastes of a liquid nature.
