1. (1) Notified the employer of an alleged violation of such statute or the AEA of 1954;
2. (2) Refused to engage in any practice made unlawful by such statute or the AEA of 1954, if the employee has identified the alleged illegality to the employer; or

(d)

1. (1) Every employer subject to the Energy Reorganization Act of 1974, as amended, shall prominently post and keep posted in any place of employment to which the whistleblower provisions of the Act apply, a fully legible copy of the notice prepared by OSHA, printed as appendix A to this part, or a notice approved by the Assistant Secretary that contains substantially the same provisions and explains the whistleblower provisions of the Act and the regulations in this part. Copies of the notice prepared by OSHA may be obtained from the Assistant Secretary for Occupational Safety and Health, U.S. Department of Labor, Washington, DC 20210, from local OSHA offices, or from OSHA's Web site at http://www.osha.gov.
2. (2) Where the notice required by paragraph (d)(1) of this section has not been posted, the requirement in § 24.103(d)(2) that a complaint be filed with the Assistant Secretary within 180 days of an alleged violation will be inoperative, unless the respondent establishes that the complainant had knowledge of the material provisions of the notice. If it is established that the notice was posted at the employee's place of employment after the alleged retaliatory action occurred or that the complainant later obtained knowledge of the provisions of the notice, the 180 days will ordinarily run from whichever of those dates is relevant.
