Exhibit 95
Section 1503(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act (the "Dodd-Frank Act") requires domestic mine operators to disclose violations and orders issued under the Federal Mine Safety and Health Act of 1977 (the "Mine Act") by the federal Mine Safety and Health Administration ("MSHA"). We do not act as the owner of any mines, but as a result of our performing services or construction at mine sites as an independent contractor, we are considered an "operator" within the meaning of the Mine Act. The mine data retrieval system maintained by MSHA may show information that is different than what is provided herein. Any such difference may be attributed to the need to update that information on MSHA’s system and/or other factors.
The following table provides information for the three months ended December 31, 2021:
