Material to be deleted in strikeout; material to be added underlined.
ARTICLE VI. SEWERS AND SEWAGE DISPOSAL*
DIVISION 1. GENERALLY
Sec. 22-210. Definitions.
The following words and terms as used in this article shall be deemed to mean
and be
construed as follows, unless the context specifically indicates otherwise:
Bi-Monthly - Once every other month.
Bi-Weekly - Once every other week.
. . .
Building sewer. The extension from the building drain to the public sewer
or other place of
disposal.
Bypass - Means the intentional diversion of wastes from any
portion of a treatment facility.
. . .
Contributor. Any person responsible for the production of domestic, commercial
or industrial
waste which is directly or indirectly discharged into the city sanitary sewer system.
Cooling Water -
(1) Uncontaminated: Water used for cooling purposes
only which has no direct
contact with any raw material, intermediate, or final product and which does not
contain a level of contaminants detectably higher than that of the intake water.
(2) Contaminated: Water used for cooling purposes only which
may become contaminated
either through the use of water treatment chemicals used for corrosion inhibitors or biocides, or
by direct contact with process materials and/or wastewater.
Daily Maximum - The maximum allowable discharge of pollutant
during a calendar day.
Where daily maximum limitations are expressed in units of mass, the daily discharge is the total
mass discharged over the course of the day. Where daily maximum limitations are expressed in
terms of a concentration, the daily discharge is the arithmetic average measurement of the
pollutant concentration derived from all measurements taken that day.
. . .
Industrial wastewater. The water-carried wastes or liquid wastes from
industrial or
commercial processes as distinguished from domestic wastewater.
Instantaneous Maximum Concentration - The maximum concentration
allowed in any single
grab sample.

samples collected during a
calendar month or specified 30-day period (as opposed to a rolling 30-day window).
. . .
Significant noncompliance (SNC). Industrial user violations which meet
one of the following
criteria:
. . .
(5) Any other violation or group of violations which the
City of Columbia determines will
adversely affect the operation or implementation of the local pretreatment program.
. . .
TSS (total suspended solids). Solids that either float on the surface
of, or are in suspension in water, wastewater or other
liquids and which are removable by laboratory filtering, expressed in milligrams per liter (mg/l).
Upset - Means an exceptional incident in which there is unintentional
and temporary
noncompliance with technology-based permit effluent limitations because of factors beyond the
reasonable control of the permittee, excluding such factors as operational error, improperly
designed or inadequate treatment facilities, or improper operation and maintenance or lack
thereof.
. . .
Watercourse. A channel in which a flow of water occurs, either continuously
or intermittently.
Weekly Average - The arithmetic mean of the values for effluent
samples collected over a
period of seven consecutive days.
. . .
Sec. 22-215. Unlawful discharges.
Except as hereinafter provided, it shall be unlawful for any person to discharge
or cause to be
discharged into any sewer any of the following described substances, materials, water or wastes:

(200) mg/l of fat, oil or grease

Sec. 22-216.3. Discharge permits.
The director is authorized to establish local pretreatment standards and conditions
for all

pretreatment standards, the director is authorized to require discharge permits of any person prior
to that person discharging wastewater into any city sewer.
. . .
(5) The permittee must submit an application for a new permit at least
90 days before the
expiration date of the permit if the permittee wishes to continue an activity regulated by the
permit after the expiration date of the permit.
(6) An expired permit will continue to be effective and enforceable
until the permit is reissued
if:
(a) The permittee has
submitted a complete permit application at least ninety
(90) days prior to the expiration date of the user's existing permit.
(b) The failure to reissue the permit, prior to expiration of the previous
permit, is not due to any
act or failure to act on the part of the permittee.
Sec. 22-217. Violations; penalties.

of this
article during the twelve (12) previous months shall be annually published by the director in a

becoming aware of the
violation; and
(b) Repeat the sampling and pollutant analysis and submit, in writing,
the results of this second
analysis within 30 days after becoming aware of the first violation.
Sec. 22-219.6 Representative sampling and flow measurements.
(a) Samples and measurements taken as required herein shall
be representative of the volume
and nature of the monitored discharge. All samples shall be taken at the monitoring point(s)
specified in this permit and, unless otherwise specified, before the effluent joins or is diluted by
any other waste stream, body of water or substance. All equipment used for sampling and
analysis must be routinely calibrated, inspected and maintained to ensure their accuracy.
Monitoring points shall not be changed without notification to and the approval of the City of
Columbia.

accuracy and reliability of measurements of the volume of monitored discharges. The devices
shall be installed, calibrated, and maintained to ensure that the accuracy of the measurements are
consistent with the accepted capability of that type of device. Devices selected shall be capable
of measuring flows with a maximum deviation of less than 10 percent from true discharge rates
throughout the range of expected discharge volumes.
Sec. 22-220. Certification statement.
(a) All wastewater discharge permit applications and user reports
must be signed by an
authorized representative of the user and contain the following certification statement: "I certify
under penalty of law that this document and all attachments were prepared under my direction or
supervision in accordance with a system designed to assure that qualified personnel properly
gather and evaluate the information submitted. Based on my inquiry of the person or persons who
manage the system, or those persons directly responsible for gathering the information, the
information submitted is, to the best of my knowledge and belief, true, accurate, and complete. I
am aware that there are significant penalties for submitting false information, including the
possibility of fine and imprisonment for knowing violations."
(b) The certification statement shall be signed
as required in (1), (2), or (3) below:

corporate procedures.
(2) By a duly authorized representative of the individual designated
in paragraph (1) of this section
if:
(a) The authorization is made in writing by the individual described in paragraph
(1);

responsibility for the
overall operation of the facility from which the Industrial Discharge originates, such as the
position of plant manager, operator of a well, or a well field superintendent, or a position of
equivalent responsibility, or having overall responsibility for environmental matters for the
company; and
(c) The written authorization is submitted to the City.
(3) If an authorization under paragraph (2) of this section is no longer
accurate because a
different individual or position has responsibility for the overall operation of the facility, or
overall responsibility for the environmental matters for the company, a new authorization
satisfying the requirements of paragraph (2) of this section must be submitted to the City prior to
or together with any reports to be signed by an authorized representative.

(a) Bypass is prohibited unless it is unavoidable
to prevent loss of life, personal injury or
severe property damage or no feasible alternatives exist.
(b) The permittee may allow bypass to occur which does not cause effluent
limitations to be
exceeded, but only if it is also for essential maintenance to assure efficient operation.
