Current through Register 2021 Notice Reg. No. 16, April 16, 2021
Section 1724.10.4 - Continuous Pressure Monitoring(a) Operators shall comply with the following requirements for well-specific injection pressure monitoring:(1) Well-specific injection pressure shall be continuously recorded at all times that a well is approved for injection by the Division, regardless of whether injection is actually occurring. An operator may satisfy this requirement by recording injection pressure from a header or manifold if approved by the Division based on a showing that the operator is able to calculate well-specific injection pressures from the recorded data. An operator may suspend continuous injection pressure recording for a well while the well is disconnected from all injection lines.(2) Injection pressure records shall be maintained by the operator as long as the well is approved for injection by the Division, and for three years after that, and shall be provided to the Division upon request.(3) On or before the last day of each month, operators shall report to the Division the highest instantaneous injection pressure for each injection well in the last preceding calendar month.(4) Digital or analog pressure recording devices may be used to meet the requirements of this subdivision. A Division-approved supervisory control and data acquisition (SCADA) or equivalent continuous real-time recording system, with automatic computer alarm notification, is not required but may be used to meet the requirements of this subdivision. Pressure recording devices shall be maintained in good working order and be calibrated as recommended by the manufacturer. Evidence of such calibration shall be available to the Division upon request.(5) The Division may waive the requirements of this section for an injection well if the operator demonstrates that the injection facilities are configured in a manner that effectively prevents injection into the injection well above the maximum allowable surface injection pressure.(b) Operators are not required to comply with subdivision (a) until April 1, 2021. Until an operator has complied with subdivision (a), the operator shall ensure that an accurate, operating pressure gauge or pressure recording device shall be available at all times, and all injection wells shall be equipped for installation and operation of such gauge or device. Gauges shall be regularly calibrated in accordance the with manufacturer's recommendations. Evidence of such calibration shall be available to the Division upon request.
