Geothermal Production Expansion Act of 2010 - Amends competitive lease provisions of the Geothermal Steam Act of 1970 to allow an area of qualified federal land (land that is otherwise available for leasing under that Act) that adjoins other land for which a qualified lessee holds a legal right to develop geothermal resources to be available for a noncompetitive lease to such lessee at fair market value per acre if: (1) the area of qualified federal land consists of not less than one acre and not more than 640 acres and is not already leased or nominated to be leased; (2) the qualified lessee has not previously received a noncompetitive lease in connection with the valid discovery for which data has been submitted; and (3) sufficient technical data prepared by a qualified geothermal professional has been submitted by the qualified lessee to the applicable federal land management agency that would lead individuals who are experienced in the subject matter to believe that there is a valid discovery of geothermal resources on the land and that such thermal feature extends into the adjoining areas.

Defines "fair market value per acre" as a dollar amount per acre that shall be: (1) equal to the market value per acre as determined by the Secretary of the Interior within 90 days after the Secretary receives an application for a lease, and (2) not less than the greater of 4 times the median amount paid per acre for all land leased under such Act during the preceding year or $50.

Directs the Secretary to: (1) publish a notice of any request for such a lease; (2) determine fair market value in accordance with procedures established by the Secretary; (3) provide to a qualified lessee and publish any proposed determination of the fair market value of the area the qualified lessee seeks to lease; and (4) provide the lessee and the public an opportunity to appeal a proposed determination during the 30-day period after the determination is provided or published, respectively. Prohibits the Secretary from accepting any nomination of land for leasing after publication of a notice of request to lease such land unless the request has been denied or withdrawn.
