Section 2. Section 15.10.015(c) is amended to read as follows:
definitions.
(1) Categorical Pretreatment Standards. "Categorical pretreatment standards" means the

CFR 403.6 and Parts 405-471].
(2) COD or Chemical Oxygen Demand. "COD" or "chemical oxygen demand" means the
measure of chemically decomposable material in domestic or industrial wastewater as represented
by the oxygen utilized as determined by the appropriate procedure described in standard methods.
(3) Code of Federal Regulations or CFR. "Code of Federal Regulations" or "CFR" means
the Code of Federal Regulations published by the Office of the Federal Register, National Archives
and Records Administration. Whenever a reference is made to any port

3 (7) Compatible pollutant. "Compatible pollutant" means biochemical oxygen demand,
4 suspended solids, pH, and fecal coliform bacteria, plus additional pollutants identified in the city's
5 National Pollutant Discharge Elimination System (NPDES) Permit if the city's treatment plant is
6 designed to treat such pollutants and if fact, does remove such pollutants to a substantial degree.
7 (8) Composite sample. "Composite sample" means a flow -proportional or time.
proportional sample, which accurately represents the average pollutant concentration discharged
9 during a continuous time period. A composite sample may be obtained manually or automatically,
10 and discretely or continuously. For manual compositing, at least six (6) individual samples from
11 each sample point shall be combined and mixed to obtain one composite sample; flow -proportion
12 may be obtained either by varying the time interval between each discrete sample and the volume
13 of each discrete sample.
14 (9) Contamination. "Contamination" means an impairment of the quality of water of the
15 State by waste to a degree that creates a hazard to the public health through poisoning or through
16 the spread of disease. "Contamination" includes any equivalent effect resulting from the disposal
17 of wastewater, whether or not waters of state are affected.
18 (10) Contractor. "Contractor" means an individual, firm, corporation, partnership, or
19 association licensed by the state to perform the type of work to be done under the permit.

22 (5) year period at the prime interest rate published in the Wall Street Journal plus two percent (2%)
23 at the time the project costs are being determined, do not exceed the total savings that would be
24 generated by the project during the same five (5) year period. Project costs shall also be
25 considered cost effective, if financing assistance is available to the discharger, from the city or any
26 other source, at a lower rate and the project costs, if financed over a five (5) year period at that
27 rate do not exceed the total savings that would be generated by the project during the same five
28 (5) year period.

(13) Critical user. "Critical user" means a discharger whose wastewater contains priority
pollutants, or who discharges waste that has the potential to cause interference, excluding
sanitary sewage.
Section 3. Subsection 15.10.040(b) is amended to read as follows:
(b) Any waste having a pH lower than 5.0 or having any corrosive or detrimental
characteristic that may cause injury to any person operating, maintaining, repairing, or constructing
the sanitary sewer system or any part thereof, or working in or about the sanitary sewer system, or
any damage to any part of the sanitary sewer system, or any waste with a pH high enough to cause
alkaline incrustations on sewer walls; or
Section 4. Section 15.10.050 is amended to read as follows:
Section 15.10.050 Limitations on wastewater strength.
No person shall discharge, cause, allow, or permit to be discharged into a public sanitary
sewer or any part thereof, any waste containing an excess in concentration of the following
substances:
Substance Maximum Allowable Concentration
Arsenic 0.08 /T
OD
BOD 1300 mg/L
Cadmium 0.138 mg/L
Copper 2.0 mg/L
Cyanide 0.292 mg/L
Lead 0.365 mg/L

a significant industrial user in accordance with 40 C.F.R. § 403.8(f)(6) even though the industrial
user meets the definition of a significant industrial user, if the director determines the following:
