Each Federal agency shall ensure that the agency will not grant a loan, loan guarantee, permit, license, or other assistance to an applicant that, with intent to avoid the requirements of section 306108 of this title, has intentionally significantly adversely affected a historic property to which the grant would relate, or having legal power to prevent it, has allowed the significant adverse effect to occur, unless the agency, after consultation with the Council, determines that circumstances justify granting the assistance despite the adverse effect created or permitted by the applicant.
