(C) Identify land use or access to the resource agreements required for the project and the schedule for securing the agreements and the term of those agreements.
(D) Identify available component warranties for the specific project location and size.
(E) Systems interconnected to the electric power system will need arrangements to interconnect with the utility. Identify utility system interconnection requirements, power purchase arrangements, or licenses where required and the schedule for meeting those requirements and obtaining those agreements.
(F) Describe all potential environmental impacts resulting from siting issues, construction and operation of the proposed project. Identify other site or design alternatives that were considered in your planning process. Identify all environmental compliance issues such as required permits (i.e. wetland fill, endangered species, Air Quality, State Water Quality Certification, etc.)
(iii) Resource assessment. The Applicant must provide adequate and appropriate evidence of the availability of the renewable resource required for the system to operate as designed. Indicate the quality of the geothermal resource including temperature, flow, and sustainability and what conversion system is to be installed. Describe any special handling of cooled geothermal waters that may be necessary. Describe the process for determining the geothermal resource including measurement setup for the collection of the geothermal resource data. For proposed projects with an established resource, provide a summary of the resource and the specifications of the measurement setup.
(iv) Design and engineering. The Applicant must provide authoritative evidence that the system will be designed and engineered so as to meet its intended purpose and need, will ensure public safety, mitigate any adverse environmental impacts, and will comply with applicable laws, regulations, agreements, permits, codes, and standards. Projects shall be engineered by a qualified entity. Systems must be engineered as a complete, integrated system with matched components. The engineering must be comprehensive including site selection, system and component selection, conversion system component and selection, design of the local collection grid, interconnection equipment selection, and system monitoring equipment. Systems must be constructed by a qualified entity.
(A) The application must include a concise but complete description of the geothermal project including location of the project, resource characteristics, thermal system specifications, electric power system interconnection equipment and project monitoring equipment. Identify possible vendors and models of major system components. Provide the expected system energy production on a monthly and annual basis.
(B) The application must include a description of the siting criteria used in selecting the project site and the reason for elimination of other site alternatives considered and address issues such as site access, foundations, backup equipment when applicable, proximity to the electrical grid, environmental issues with emphasis on land use, air quality, water quality, noise pollution, soil degradation, wildlife, habitat fragmentation, aesthetics, odor, and other construction, and installation issues applicable to this type of technology. Identify any unique construction and installation issues.
(C) Sites must be controlled by the agricultural producer or small business for the proposed project life or for the financing term of any associated federal loans or loan guarantees.
(v) Project development schedule. The Applicant must identify each significant task, its beginning and end, and its relationship to the time needed to initiate and carry the project through startup and shakedown. Provide a detailed description of the project timeline including resource assessment, system and site design, permits and agreements, equipment procurement, and system installation from excavation through startup and shakedown.
