AN ORDINANCE AMENDING. SECTION 14.20 OF THE CENTRAL POINT
MUNICIPAL CODE REGARDING SAMPLING AND FLOW MEASUREMENT
WHEREAS, the Council has determined that the amendments as
set forth herein a"re just and equitable, and in the best
interests of the citizens of the City of Central Point, now,
therefore,
' THE PEOPLE OF THE CITY OF CENTRAL POINT, OREGON DO ORDAIN AS
FOLLOWS;
~~ Section 1: Section 14.20.020 of the Central Point Municipal
Code is hereby amended. to read as follows:
14.20.020 Sampling and flow measurement. A. Each indus-
`rtral user discharging industrial wastes into a public sanitary
sewer may, at his option, or shall, when directed by the plant
- superintendent, construct and maintain an approved control
" manhole, together with such a flaw measurement, flow sampling and
sample storage facilities for all wastewater entering the public
sewer as may be required by the plant superintendent. These
facilities will be used to obtain flow, BOD, and suspended solids
data for use as a basis for a wastewater charge. In lieu of
directing the construction of measurement sampling and sample
storage facilities,.the plant superintendent may require that
peach person discharging industrial wastes into a public sanitary
sewer to procure and test at the person's expense and in a manner
approved by the plant"superintendent, sufficient. composite
samples on which to base and compute the person's wastewater
charge:,, .
B;.~ Ln the event that automatic f ow measurement, sampling,
and sample storage faciltiess" are not provided,"the wastewater
charge shall be computed using 'the meter water flow to the
. ~ premises as a_basis for wastewater flow and,the laboratory
,~ analysis of .,composite samples"procured as directed by the. plant
superintendent as a basis for computing wastewater concentra-
tions. Metered water flow shall include all water delivered to
or used on the. pr=emises~arid which is discharged to regional
facilities. All metered flows shall be metered at the industrial
- `user's expense. Cooling waters or water not discharged to a
,` `.;sanitary sewer shall be separately metered at the industrial
.user's expense using deduct meters or any other manner approved
"`by:the,plant superintendent prior to allowing deduction of such
flow. from the total water-used on the premises. in computing. the

wastewater charge.
•~` _ C"' Wastewater concentrations shall be determined by the
av_erage.of each day'_s composite sampletaken a, minimum of three
~`-.tines`per year for the. initial year and at least once in every
-.subsequent eighteen months. A composite sample is a series of
samples `mixed together so as to approximate the average strength
':' ~~`of discharge to the. sewer. Said composite sample for each day
' '-may consist of a pool of twenty-four samples, each taken hourly,
and shall be flow. proportioned. The sampling period may include
any ,twenty-four consecutive hour period, not necessarily midnight
to-:midnight. If .unusual effluent conditions make the calcula-
-bons by the composite method impossible or unrealistic, then. by
_- -.mutual agreement, another method of sampling and computation may
"', be, implemented.
: D.f Analysis that, in the discretion of the plant super-
interident, justifies a change in an industrial user's extra
strengthi`service charge and thereby requires modification of the
=user's permit, shall be transmitted by the plant superintendent
.~ or Yiis~designee, together with notification of the proposed
~;•`.mod'fcaton as required by Section 14.16.090 of this Title, to
- the City,;: Administrator and to the industrial user in writing at
~~>~-least 30` days prior to the effective ~dat~e of any change in the
:industrial user's service charge and the effective date of the
mpermit modification.. Any changes in extra strength charges
charged, by the City `to the `industrial user shall become effective
concurrently with the change in rates charged to the City by
,. .the, City. of Medford,. which changes are effective for the month
next ;following the month' i~n;.which the plant superintendent gives
the no?tice as hereinabove required. The method to determine
. - :•service charges for wastewater shall be as provided in Chapter
1.4.32 of this Title.
