All personnel actions affecting employees or applicants for employment who are at least 40 years of age (except personnel actions with regard to aliens employed outside the limits of the United States) in military departments as defined in section 102 of title 5, in executive agencies as defined in section 105 of title 5 (including employees and applicants for employment who are paid from nonappropriated funds), in the United States Postal Service and the Postal Regulatory Commission, in those units in the government of the District of Columbia having positions in the competitive service, and in those units of the judicial branch of the Federal Government having positions in the competitive service, in the Smithsonian Institution, and in the Government Publishing Office, the Government Accountability Office, and the Library of Congress shall be made free from any discrimination based on age.

Except as otherwise provided in this subsection, the Equal Employment Opportunity Commission is authorized to enforce the provisions of subsection (a) through appropriate remedies, including reinstatement or hiring of employees with or without backpay, as will effectuate the policies of this section. The Equal Employment Opportunity Commission shall issue such rules, regulations, orders, and instructions as it deems necessary and appropriate to carry out its responsibilities under this section. The Equal Employment Opportunity Commission shall—

The head of each such department, agency, or unit shall comply with such rules, regulations, orders, and instructions of the Equal Employment Opportunity Commission which shall include a provision that an employee^* or applicant for employment shall be notified of any final action taken on any complaint of discrimination filed by him thereunder. Reasonable exemptions to the provisions of this section may be established by the Commission but only when the Commission has established a maximum age requirement on the basis of a determination that age is a bona fide occupational qualification necessary to the performance of the duties of the position. With respect to employment in the Library of Congress, authorities granted in this subsection to the Equal Employment Opportunity Commission shall be exercised by the Librarian of Congress.

Any person^* aggrieved may bring a civil action in any Federal district court of competent jurisdiction for such legal or equitable relief as will effectuate the purposes of this chapter.

When the individual has not filed a complaint concerning age discrimination with the Commission, no civil action may be commenced by any individual under this section until the individual has given the Commission not less than thirty days’ notice of an intent to file such action. Such notice shall be filed within one hundred and eighty days after the alleged unlawful practice occurred. Upon receiving a notice of intent to sue, the Commission shall promptly notify all persons named therein as prospective defendants in the action and take any appropriate action to assure the elimination of any unlawful practice.

Nothing contained in this section shall relieve any Government agency or official of the responsibility to assure nondiscrimination on account of age in employment as required under any provision of Federal law.

Any personnel action of any department, agency, or other entity referred to in subsection (a) of this section shall not be subject to, or affected by, any provision of this chapter, other than the provisions of sections 626(d)(3) and 631(b) of this title and the provisions of this section.
