Metering and Reporting Withdrawal Requirements from the Denver Basin Aquifer Wells Permitted Pursuant to Section 37-90-107(7), C.R.S.: In order to administer these wells, the State Engineer shall require the permittee to
install and maintain a totalizing flow meter to measure all withdrawals from the well. As a minimum, the meter shall be installed according to manufacturer's recommendations and shall contain sufficient recording digits to assure that "roll over" to zero does not occur within three years. The meter shall be maintained by the permittee so as to provide continuous, accurate records of withdrawal. If the meter is not operational, the well shall not be pumped. The State Engineer may approve a substitute totalizing measuring device if it is capable of recording or can be used to calculate the total volume pumped. The permittee shall report the amount of withdrawal from the permitted well as reasonably required by the State Engineer.

Geophysical logs are required for all new wells permitted pursuant to Section 37-90-107(7), C.R.S. unless there
is an existing geophysical log from that aquifer located within 1,320 feet of the proposed well which is acceptable to the State Engineer and is representative of the aquifer conditions at the location of the permitted well. The permittee will be responsible for obtaining and submitting a copy of the existing geophysical log unless it is currently on file in the State Engineer's Office. If the new well is geophysically logged, the permittee is responsible for obtaining and submitting those required geophysical logs to the State Engineer's Office as follows: 1) The minimum requirements will be for both resistivity and spontaneous potential (SP) logs, which must be obtained prior to the installation of the well casing. 2) The resistivity log must record values at approximately one-and three-foot depths of investigation. 3) The vertical scale shall be either one inch equals twenty feet, or one inch equals fifty feet. 4) If additional types of logs, including gamma, neutron, porosity, sonic, single point resistance, and caliper, are obtained, copies of these logs shall also be submitted to the State Engineer's Office. 5) The entire set of logs must be submitted to the State Engineer's Office within sixty (60) days following collection of the data or within seven days after the expiration date of the well permit, whichever is earlier. The log shall be identified by the well permit number. 6) If a permittee, or an applicant drilling a test hole, desires to use other geophysical logs to meet the minimum requirements, they must apply in writing to , and obtain approval from the State Engineer's Office prior to well construction. 7) In the event that the data provided contains trade secrets, privileged information, or confidential commercial, financial, geological or geophysical data, the State Engineer shall deny the right of inspection of such data to any person and keep the data confidential pursuant to C.R.S. 24-72-204(3)(a)(IV), provided the applicant notifies the State Engineer in writing requesting such protection. The State Engineer may require the applicant to submit the geophysical well logs prior to the casing of the production well in order to determine the appropriate producing intervals. In such a case, the State Engineer shall inform the applicant of the appropriate producing interval within two working days of receipt by the State Engineer of the geophysical logs.
