Section 2 CCR 404-1-1315 - GEOTHERMAL RESERVOIR MONITORINGa. On a Form 4, Sundry Notice, Operators of Deep Geothermal Wells and Geothermal Science Wells will report the initial state of the Geothermal Resource, obtained as soon as practicable after Completion of such Well, by providing data of temperature and pressure, as well as initial flow rates and volumes if a flow test was done.b. On a Form 4, Sundry Notice, Operators will provide observation well records within 30 days of any measurement taken in an observation well, or temperature gradient well, including temperature and pressure readings.c. Operators will annually report a summary of Fluid usage by submitting a Form 4 Sundry to the Deep Geothermal Facility: (1) For any Open-Loop Geothermal System, Operators will submit a summary of the difference between the volumes of Fluids produced and injected, including any fluid loss, and the volume and source of makeup water, if any.(2) For any Closed-Loop Geothermal System, Operators will submit a summary of types and volumes of Fluids used in the system, including any fluid loss.d. Where the Director believes it is necessary to prevent waste, prevent the degradation of the geothermal resource, protect correlative rights, or to protect and minimize adverse impacts to public health, safety, welfare, the environment, and wildlife resources, the Director may require subsurface temperature or pressure measurements.e. The Director may require injection and/or reinjection of fluid where necessary for the maintenance of underground pressures, the prevention of subsidence, or the disposal of brines.47 CR 17, September 10, 2024, effective 9/30/2024
