Summary

License holders must begin building the project within the time set in their license, which cannot be more than two years after the license date. After starting, they must keep working in good faith and with reasonable effort to finish the parts the commission says are needed to meet the market, and then build additional parts as the commission directs until the whole project is done. The commission can extend the start deadline by up to 8 more years, and can extend completion deadlines when that does not conflict with the public interests. If the holder does not start on time, the commission will give notice and can cancel the license for those works. If work is started but not finished on time, the Attorney General, at the commission’s request, will ask a federal district court to revoke the license, order sale of what was built, and seek other court-ordered relief under section 820.

The licensee shall commence the construction of the project works within the time fixed in the license, which shall not be more than two years from the date thereof, shall thereafter in good faith and with due diligence prosecute such construction, and shall within the time fixed in the license complete and put into operation such part of the ultimate development as the commission shall deem necessary to supply the reasonable needs of the then available market, and shall from time to time thereafter construct such portion of the balance of such development as the commission may direct, so as to supply adequately the reasonable market demands until such development shall have been completed. The periods for the commencement of construction may be extended for not more than 8 additional years, and the period for the completion of construction carried on in good faith and with reasonable diligence may be extended by the commission when not incompatible with the public interests. In case the licensee shall not commence actual construction of the project works, or of any specified part thereof, within the time prescribed in the license or as extended by the commission, then, after due notice given, the license shall, as to such project works or part thereof, be terminated upon written order of the commission. In case the construction of the project works, or of any specified part thereof, has been begun but not completed within the time prescribed in the license, or as extended by the commission, then the Attorney General, upon the request of the commission, shall institute proceedings in equity in the district court of the United States for the district in which any part of the project is situated for the revocation of said license, the sale of the works constructed, and such other equitable relief as the case may demand, as provided for in section 820 of this title.
