SECTION 5. ~UTHORITY TO DISCONNECT SERVICE.

processes are released to the sewer causing rapid deterioration of these structures
or interfering with proper treatment of sewage, the City is authorized immediately
to terminate service by such measure as are necessary to protect facilities.

effluent from the treatment plant is no longer of a standard permitted for
release into the watercourse and it is found that the owner is delivering
waste water to the City1s system that cannot be sufficiently diluted by mixing
with the City's waste or requires treatment that is not prOVided by the City
as normal domestic treatment. In this instance, the City shall immediately
supply the owner with the governmental agencies report and provide the owner
with all pertinent information. The owner's waste line will then be disconnected
when the City is informed that it can no longer continue to release their
effluent into the watercourse. The owner1s waste treatment service shall
remain disconnected until such time that the owner has provided additional pretreatment
facilities designed to remove the objectionable cause from YWner's industrial

SECTION 4. ij"URCHARGE FOR WASTES OF ABNORMAL STRENGTH.
A norml'll service charge shall be established by the City of Colleyville
for any person, firm, owner or corporation discharging wastes into the system,
provided that the B.O.D. in the waste water or the suspended materials does
not exceed the normal concentration of two hundred fifty (250) ppm.
When either the B.O.D. or the suspended solids or both are found
to exceed the stated two hundred fifty (250) ppm at the point entering t~e
City's system, a surcharge shall be applied to the billing rate by multiplying
the normal service base rate by the factor obtained from dividing the actual
measured B.O.D. by two hundred fifty and also by the factor obtained from
dividing the actual measured suspended solids by two hundred-fifty, each such
factor to be applied individually and only when greater than one. The surcharge
will be made for each factor that exceed one and shall be additive.
The determination of B.O.D. end suspended materials shall be
by an independent laboratory selected by the City. The time of selection of
the sample shall be at the sole discretion of the City. Tbe applicable surcharge
determined by such tests shall be retro-active for two billing periods and shall
continue for six (6) billing periods unless subsequent tests determine that the
eurcharge should be further increased.
When any such tests made at the discretion of the City shows that
a eurcharge shall be applied, continued or increased over the base rate, whichever
is applicable, then the O\vner shall be billedlt the rate of Five Dollars ($5.00)
for each test to cover the cost of sampling, mailing and handling plus the
laboratory fees. When a surcharge is in effect, the test will be made at least
fifteen (15) days. When such tests made at the discretion of the City reveals
that the surcharge is no longer applicable, then no costs will tie made to the
owner for such test or tests.

SECTION 9.
SEVERABILITY. If any section, paragraph, subdivision,
clause, phrase or provision of this ordinance shall be judged invalid or held
unconstitutional, the same shall not in any manner be so construed as to effect
the validity of the remainder of this ordinance as a whole or any part or
provision thereof, other than the part so decided to be invalid or unconstitutional.
SECTION 10.
~MERGENCY.
The fact that the City of Colleyville
is in need of the above ordinance and there does not now exist any such ordinance
creates an emergency and imperative necessity requiring the suspension of any
rule that requires that ordinances should be read at three separate meetings
of the Council, and such rule is hereby suspended and this ordinance shall be
effective from and after its passage and publications as required by law.
