CODE OF COLORADO REGULATIONS 2 CCR 402-16 Division of Water Resources i. PCC computed from the PCC Test performed between June 15 and October 15 of the same calendar year shall be used to compute the amount of water diverted from the date of the PCC Test forward up to the date of any subsequent PCC Test. (2) PCC Tests performed between October 16 of any year and the following June 14 shall be valid until the following August 14. An additional PCC Test shall be performed during the period June 15 through August 14 following that PCC Test. Should a subsequent PCC Test not be performed by the following August 14, no water shall be withdrawn from the Well after August 14 until an acceptable PCC Test is approved by the Division Engineer. i. The PCC computed from the PCC Test performed before June 15 shall be used to compute the amount of water pumped from the date of the PCC Test forward up to the date of the subsequent PCC Test. ii. A subsequent PCC Test is required to be performed during the period June 15 through August 14 and that PCC shall be used to compute the amount of water pumped from the date of the PCC Test forward until any subsequent PCC Test. C. A PCC Test shall be required more frequently than described above, and prior to any diversions from the Well, if any of the following occur: (1) A new or re-worked pump and/or motor are installed on the Well. (2) The Well is re-worked to change the yield of the Well. (3) The system that the pump discharges into is modified in such a manner as to change the PCC, the discharge of the pump, or the operating pressure. (4) Any other alteration to the system which changes the discharge of the pump, the operating pressure, or PCC. (5) Additional PCC Tests may also be required if the State Engineer conducts or reviews PCC Tests and determines an error was made, or if any changes to the Well Distribution System or ground water levels will make the use of the PCC, based upon the current PCC Test, inaccurate by 5% or more. d. Use of a PCC may not be appropriate where varying terrain results in inaccurate calculations due to the differences in elevations to which the water must be pumped unless the system has working pressure regulators installed. e. If the difference between the current approved PCC and the results of the next subsequent PCC is greater than 10%, the new PCC shall be considered invalid and a PCC will not be considered a valid Alternative Method of Measurement for the Well from the date of the new PCC Test forward, unless the Well User submits and obtains approval by the Division Engineer of a variance to allow the PCC. 5
