4. -Tributary welles). are those wells that produce underground water and
ground water as defined in section 37-92-103(11), C.R.S.

B. AJJ.y other term used in these rules:thaIt is defined in Anicle 90 or 92 is used with
the meaning given therein.

Rule 3. All wells within the scope of these rules shall either, by July 1S, 1994, be equipped with
a totalizing flow meter that is i,ostalled and main~iuedaocording to m~nllfadUrer's specifications and
rec:oD:uoendatioDS or. by October 1. 1994, be rated to detecminc a' pow<< coefficient.

3.1 When a totalizing flow meter is used., it shall be the. owner's responsibility to keq> the meter in
acceptable operating condition. Any meter designed and manufactured for the purposeof,~uriog the
flow of water, and which has a totalizing feature; shall be considered to bc~ acceptable for pwrposes of
these rules. The State Engineer may adopt standards and specifications for the installation, repair, and
I'l)aint~.n,,~ of meters. As a minimum, totalizing flow meters ,shall be: properly verified in .the field
to be in accurate working ..condition UDder the ~upervision of an individual or entity approved annually
by the State,~ to do such tests when installed;,cootain sufficient rea>rding digits to assure that
-roll over- to zero does not occur within three years; and shall be maintained by the well owner so as
to provide a continuous, accurate record of withdrawals. If the meter is not operational, the well shall
not be pumped unless a working meter is installed or unless a specific backup water measurement
program approved by the State Engineer is put into effect. Totalizing flow meters are required to be re-
verified in the field to be in accurate working condition under the supervision of an individual or entity
annually approved by the State Engineer every four years after the date of original installation and flow
meters in existence as of the effective date of these rules shall be certified to be in accurate working
condition under the supervision of an individual or entity annually approved by the State Engineer by
June 15" 1995, and re-verified to be in accurate working condition every four years thereafter. The
Division Engineer shall be notified in writing of the date and person performing the re-verification .

3.2 The State Engineer may adopt standards and specifications for power coefficient testing. As a
minimum. power coefficients shall: be determined utilizing rating procedures approved by the State
Engineer and conducted under the supervision of an individual or entity annually approved by the State
Engineer to do such tests ; be conducted when the pumping system has stabilized, i.e., both operating
pressure and pumping drawdown has no~ changed more than 10% in the last hour; have been determined
on or after April 1. 1992; and be updated through re-rating at least every four years. The Division
Engineer shall be notified in writing of the date and person perfo~g the re-rating.

3.3 If the well(s) are part of a complex or compound system, or if the pump is driven by internal
combustion means. the owner or user of the well must utilize the totalizing flow meter method and the
provisions of Rule 3.1 apply.

;
3.4 All flow measuring equipment utilized in verification '6t accuracy and working condition in the
field and/or rating of wells must provide an accuracy within pltk..o.f minus 5 %.
