Division of Water Resources
C. Interim Water Measurement Program
Should any approved measurement device or method cease to operate accurately or fail
Verification at any time, or if changes are made to the Well or the Well's Distribution System that
would result in a change to the current PCC, the Well User shall immediately Notify the Division
Engineer and establish an Interim Water Measurement Program until the meter is replaced or
repaired or a new PCC test is performed and approved. If the TFM is not replaced or repaired
and Verified to be in accurate operating condition or a new PCC is not performed within 14
calendar days of the Notification to the Division Engineer, the Well shall not be operated until the
TFM is replaced or repaired, or a new PCC is approved or until the Division Engineer grants a
variance.
D. Measurement Method Verification Testing
The Well User shall provide Measurement Method Verification to the Division Engineer in a
format prescribed by the State Engineer within 30 calendar days of the Verification. Measurement
Method Verifications must be performed no later than the expiration date of the current
Verification.
E. Complex or Compound Systems
If the Well(s) are part of a Complex System or Compound System, or if the pump is not powered
by electricity, or the Well produces from a confined aquifer, the Well User must utilize a TFM
(Rule 16.5.A.).
F. Testing Equipment Calibration
All flow measuring equipment utilized in verification of accuracy and working condition of TFMs or
to obtain a PCC in the field must be calibrated every two years to be accurate within plus or
minus 2%, unless a variance is granted by the Division Engineer. Calibration and certification of
accuracy of such testing equipment must be accomplished by a facility qualified and equipped to
certify a test meter as accurate in accordance to this Rule using National Institute of Standards
and Technology(NIST)traceable standards.
G. All Wells newly incorporated into the Scope of the Rules as a result of these amendments, shall
be required to comply with these Rules in their entirety no later than April 1, 2016.
