4. 4 | US DOE Geothermal Programeere.energy.gov GRR Content: Colorado Permitting Concerns Uncertainty Since geothermal is so new to this state, state agencies (e.g. Department of Water Resources) aren’t quite sure how they will handle every situation. This causes angst and misunderstanding with the general public (they think there are requirements that may or may not be there, and are insisting the developer follow these "ideas”) Leasing State Land Board has not formalized their renewable energy leasing process - there are no resources online or guidance for how to obtain a lease. Plan to present recommendations to the State Land Board soon (in April?). Geothermal Resource is the heat, but does not include water - for example, EGS heat okay. Water rights must be obtained independently. Tributary vs. Nontributary Status DWR and CGS have suggested that a developer WANTS their resource to be tributary because a nontributary source is limited by surface ownership, and by total volume available by law (calculated 100-year life). There would never be enough water in a non- tributary water right that is tied to land ownership for an ecumenically viable power plant. Geothermal Well Permitting current process assumes non consumption of the tributary (see previous bullet) water. If any of it is consumptive, DWR is not yet sure how it will be handled - how to obtain a water right. NREL is working with DWR to flesh out that portion of the flowchart. County Regulations (1041 Permits) Allows the counties to develop their own geothermal permitting and regulations - relates to siting and zoning. The state has received grant money for suggested guidelines which are in process and scheduled for draft release March 15, 2013. Flow charts will be developed as part of 1041 regs and could be incorporated into the geothermal road-mapping effort. In some areas, while 1041 permits are in the process of development a moratorium on development has been adopted.

5. 5 | US DOE Geothermal Programeere.energy.gov GRR Content: Texas Permitting Concerns Water Rights Much of the surface water is already over-appropriated. Ground water is owned by the private landowner in most cases, and therefore, water leases typically need to be worked out through these land owners. Leasing Most geothermal development will occur on private lands in Texas Geothermal Resource Per TX NR Code 141.003, geothermal energy includes the heat and any associated resource, therefore a developer can utilize gas and oil that come up when drilling for geothermal resources. Another Texas statute states that geothermal will be administered as a mineral (but this does not mean it is a mineral right). Geothermal Well Permitting Many of the permits required for geothermal development (along with oil and gas) has been delegated to Railroad Commission (RRC), including drilling permits, underground injection control, air quality, etc. Transmission/ Power Plant Siting The Texas PUC has delegated authority to ERCOT (85% of the state), and therefore only retained jurisdiction in non-ERCOT areas or where the energy facility generation capacity is less than 10MW.
