In this proceeding, the United States Postal Service (USPS) was issued a one-item citation with a proposed penalty of $10,423 under the Occupational Safety and Health Act of 1970 (the Act), 29 U.S.C. § 651 et seq., by the United States Department of Labor’s Occupational Safety and Health Administration (OSHA) for violating an OSHA general housekeeping standard, 29 C.F.R. § 1910.22(a)(1), when ceiling tiles allegedly “were not kept in sanitary condition in that water stains and discoloration were observed.” (Compl., Ex. A.) After USPS timely contested the citation, the Secretary of Labor filed a formal complaint with the Commission seeking an order affirming the citation and proposed penalty. A bench trial was held in Birmingham, Alabama.
