Geothermal Development in Oregon
In Oregon, geothermal resources, including hot brines and waters associated with the resource, are considered minerals for regulatory purposes. Oregon uses a temperature threshold to define geothermal resources. In order to be considered a “geothermal resource” the highest-temperature in a given geologic formation must be greater than 250 degrees Fahrenheit. See ORS 537.090 and ORS 522.
Initially, geothermal developers in Oregon need to ensure that the applicable local Land Use Plan (LUP) allows for geothermal exploration and development projects.
If the geothermal resource is greater than 250 degrees Fahrenheit, the developer may apply for a geothermal lease by way of either a competitive bid lease sale or a non-competitive leasing process through the Oregon Department of State Lands (ODSL). If the resource is not greater than 250 degrees Fahrenheit (hereafter “low-temp”), developers may still be able to extract low-temp resources by complying with Oregon water laws for rules related to water appropriation and drilling water wells, administered by the Oregon Water Resources Department (OWRD). In addition to a lease, developers may also need any required easements to access state lands, including any necessary permits to encroach on existing state Rights-of-Way (ROWs).
To conduct certain exploration activities, developers may need a Geothermal Exploration Permit, Geothermal Prospect Well Permit, or Exploration Injection Well Permit. Developers must obtain a Geothermal Exploration Permit from the Oregon Department of State Lands (ODSL) if the proposed exploration activities will be on state land and disturb more than one surface acre or involve drilling to a depth greater than 50 feet. Developers seeking to drill a prospect well must obtain a Geothermal Prospect Well Permit from the Oregon Department of Geology and Mineral Industries (OGMI). Developers seeking to commence new injection activities must obtain an Exploration Injection Permit from the Oregon Department of Environmental Quality (ODEQ).
Geothermal development operations, including drilling, redrilling, or deepening of a geothermal well require an approved Geothermal Well Permit from the Oregon Department of Geology and Mineral Industries. The permit is intended to allow for the commencement of drilling and drilling related activities (conductor pipe, well pad, access road construction, etc).
For geothermal operations that include the injection and removal of fluids, developers proposing to construct, operate, modify, or abandon an underground injection control (UIC) well must obtain an Industrial Individual Water Pollution Control Facility (WPCF) Permit from the Oregon Department of Environmental Quality (DEQ). The requirement may apply to geothermal closed loop systems, dewatering injection systems, roof drains and some stormwater injection systems.
To produce the geothermal resources and convert the resource to marketable electricity, construction of a power plant requires initiation of the State Power Plant Commissioning Process. The Oregon State Siting Board has siting jurisdiction over electric power generating plants with an average electric generating capacity of 35 MW or greater under ORS 469. If the power plant will have an electric generating capacity of 100 MW or more, developers must initiate the Standard State Power Plant Commissioning process. If the generating capacity will be less than 100 MW the plant may be eligible for the Expedited Plant Commissioning Process. If the resource is less than 250 degrees Fahrenheit (hereafter “low-temp”), ORS 537 governs the project and requires a Permit to Appropriate from the OWRD unless the 5,000gal/day industrial/commercial use exception applies. If the resource is 250 degrees or greater, ORS 537.090 exempts the associated water from appropriation provisions of Oregon water law and the development is not subject to the provisions of ORS 537.
Where the geothermal facility requires the use of water for ancillary purposes involved in geothermal development projects (cooling water, dust suppression, etc.), developers will likely need to obtain water through a surface water use permit, unless the aforementioned exception in OAR 690-230-0130 applies.
Prior to commencing geothermal well plugging and abandonment procedures, developers are required to notify the Oregon State Department of Geology and Mineral Industries (DOGAMI). After abandonment operations are complete, the developer must file a Plugging Record Form with the DOGAMI.
Federal Regulations and Permits for Geothermal Development
Initially, geothermal developers need to ensure that the applicable Land Use Plan (i.e., Resource Management Plan (RMP)) allows for geothermal exploration and development projects. In order to conduct certain exploration activities, developers need permission from the Bureau of Land Management (BLM) or United States Forest Service (USFS). Exploration activities may require review under the National Environmental Policy Act (NEPA). Whether nominated by the BLM or by a developer, eventually developers need to obtain a Lease for Geothermal Resources (Form 3200-024a) overlying the land for any activities beyond geothermal exploration covered under a Notice of Intent to Conduct Geothermal Resource Exploration Operations (Form 3200-009) (NOI).
For ancillary activities related to development and not covered under a geothermal lease, developers may need to obtain a right-of-way (ROW) over federal land from the applicable surface land management agency. Geothermal development operations, including drilling, require an approved Geothermal Drilling Permit (Form 3260-002) (GDP) and typically an approved Plan of Operations (POO) from the BLM, which will also require NEPA review. In order to produce the geothermal resources and convert the resource to marketable electricity, developers need an approved Plan of Utilization (POU) for the construction of a power plant and related activities. Finally, the developer must plug and abandon geothermal wells that are no longer in use or demonstrated to be potentially useful, if directed to do so by the BLM.
Land Use Planning
Geothermal projects on federal land must be consistent with the applicable Land Use Plan (LUP). Most projects on federal land will be subject to the administration of either the BLM or the USFS. In 2008, the BLM and USFS, in cooperation with the United States Department of Energy (DOE), issued a Record of Decision (ROD) to amend RMPs for geothermal leasing in the western United States. The ROD amended 114 BLM land use plans in the 11 western states and Alaska by using a Programmatic Geothermal Environmental Impact Statement (PGEIS). Geothermal projects sited within the RMP areas affected by the PGEIS will not require a revision or an amendment. Geothermal projects sited outside of the RMP areas affected by the PGEIS may require an amendment to the applicable LUP/RMP.
Generally, developers will obtain a Notice of Intent to Conduct Geothermal Resource Exploration Operations (Form 3200-009) (NOI) on federal lands from the BLM. Exploration activities that “ordinarily lead to no significant disturbance of federal lands, resources, or improvements” 43 CFR 3200.1 qualify as “Casual Use” activities and do not technically require a permit. CU geothermal exploration activities generally include the use of all-terrain vehicles, two-meter probe surveys, magnetotelluric surveys, gravity surveys, geochemical surveys, archaeological surveys, and water sampling. In practice however, developers typically submit an NOI even for CU exploration activities. If the lands are managed by the USFS and not covered under a geothermal lease, developers must obtain an Exploration Permit directly from the USFS. If managed by the USFS but already subject to a geothermal lease, developers will go through the NOI process with the BLM. An approved NOI is tantamount to a permit to explore. In addition to CU exploration activities, an NOI can also allow for seismic surveys, electromagnetic surveys, and the drilling of temperature gradient wells. 43 CFR 3200.1. The aforementioned more invasive exploration activities can still bypass an otherwise more lengthy NEPA review by way of a Categorical Exclusion (CX). 43 CFR 3250. A CX is only applicable to drilling temperature gradient wells so long as there is no new associated well pad or access road construction. Any additional drilling beyond a temperature gradient well required to confirm the existence of geothermal resources will require an approved Geothermal Drilling Permit (Form 3260-002) (GDP). GDPs are not eligible for CX classification for purposes of NEPA review, likely requiring either an Environmental Assessment (EA) or Determination of NEPA Adequacy (DNA). Generally, a DNA will only suffice for subsequent GDP applications, where the original EA contemplated more wells than the amount proposed. Upon completion of exploration operations, if the BLM approved a NOI, the developer must send the BLM a complete and signed Notice of Completion of Geothermal Resource Exploration Operations (Form 3200-010). 43 CFR 3253.11.
In order to obtain federal geothermal mineral rights, developers must obtain a Geothermal Lease from the BLM. A Geothermal Lease conveys the exclusive right to drill for, extract, produce, remove, utilize, sell, and dispose of all geothermal resources in the lands subject to the lease. Lease for Geothermal Resources (Form 3200-024a).
Geothermal resources include:
- All products of geothermal processes, including indigenous steam, hot water, and hot brines;
- Steam and other gases, hot water, and hot brines resulting from water, gas, or other fluids artificially introduced into geothermal formations;
- Heat or other associated energy found in geothermal formations; and
- Any byproducts.
Given the rights conveyed and the applicable definition of “geothermal resources,” developers do not need to obtain a state water right related to the extraction of hot water and brines that are part of the geothermal resource/formation. The right to extract water, brines, and fluids for the purposes of geothermal development is inherent in the rights conveyed under a federal geothermal lease. If the project lands are available for lease, the BLM will hold an oral competitive auction and the lands will be offered to the highest qualified bidder. If no one bids on the leases in the competitive auction, developers may obtain a lease through a non-competitive process.
If the project is located on tribal lands, developers will negotiate with the appropriate tribe for a lease, which must be approved by the Bureau of Indian Affairs (BIA).
Issuing a Geothermal Lease constitutes a “major federal action” that triggers NEPA review. However, the previously discussed PGEIS allows for the issuance of geothermal leases without additional NEPA review by way of a Determination of NEPA Adequacy (DNA) tiered to the environmental review conducted for the amended RMP. For lands not within the 114 RMPs covered by the PGEIS, the BLM must conduct a NEPA review prior to issuing or making lands available for geothermal leasing.
Rights of Way
If federal land is required for ancillary activities related to development and is not covered by the geothermal lease, developers must obtain ROW access from the BLM or other federal agency. Ancillary activities may include transmission lines, roads, and other access. If the aforementioned activities are on USFS managed surface land, developers must obtain a special use authorization from the USFS. Similarly, for ancillary activities on Bureau of Reclamation (BOR) managed land, developers must obtain a Use Authorization from the BOR.
Well Field Development
In order to conduct drilling operations on federal land, developers must obtain an approved Geothermal Drilling Permit (Form 3260-002) (GDP) and POO from the BLM. Title 43 CFR 3261 Drilling Operations: Getting a Permit. If another federal agency manages the surface of the lease, that agency will be involved in the application review process. GDPs require NEPA review, either in the form of a DNA, EA, or Environmental Impact Statement (EIS). Generally, a DNA will only suffice for subsequent GDP applications, where the original EA or EIS contemplated more wells than the amount proposed.
In order to produce the geothermal resources and convert them to marketable electricity, developers need an approved POU for the construction of a power plant and related activities. A POU involves a Utilization Plan, Facility Construction Permit 43 CFR 3272, Site License 43 CFR 3273, and Commercial Use Permit 43 CFR 3274. Developers must participate in an application coordination meeting, which may be combined with the required on-site visit. Developers must complete the environmental review process under NEPA before the Site License and Facility Construction Permit will be approved by the BLM. After construction of the power plant, developers must obtain the Commercial Use Permit prior to commencing commercial operations under a federal lease, a federal unit, or a utilization facility. 43 CFR 3274.10.
Developers may choose to seek status as a Qualifying Facility (QF) under the Public Utilities Regulatory Act (PURPA). QF status provides certain benefits under the law. For example, QFs have the right to sell energy or capacity to a utility, the right to purchase certain services from utilities, and relief from certain regulatory burdens.
Developers may qualify as Exempt Wholesale Generators if they are independent power producers that exclusively sell energy to wholesale customers and complete the self-certification process overseen by the Federal Energy Regulatory Commission (FERC). Obtaining EWG status can exempt the generator from certain reporting and accounting regulations under the Energy Policy Act of 2005 and allows the generator to sell power at market-based rates.
A geothermal lessee/operator is required to promptly plug and abandon geothermal wells that are no longer in use or demonstrated to be potentially useful. Title 43 CFR 3263 Well Abandonment. The BLM may verbally order the operator to abandon a well or the operator may request verbal approval from the BLM to plug a well. In either case, the operator must submit a well plugging or abandonment report upon completion. 43 CFR § 3263.11
