Due to the risk of personnel injury from arc flash hazards at nuclear plants, we performed an evaluation to determine if (1) TVA’s arc flash procedures were being performed as required, (2) required personal protective equipment was available and properly maintained, and (3) required training was completed. We found some requirements of TVA’s arc flash procedures were not being performed. Specifically, (1) arc flash hazard analyses were incomplete, not reflective of current plant operating conditions, and not reviewed timely; (2) identified hazards were not communicated accurately to workers; (3) plants had not adequately evaluated and implemented controls to reduce exposure to high hazard incident energies; and (4) hazards and mitigations were not routinely documented.In addition, we determined arc flash training needs improvement. TVA’s identified population of individuals required to have arc flash training had completed initial training; however, the trainee population was incomplete and not a reliable indicator as to who is required by the Occupational Safety and Health Administration to receive the training. TVA has also not implemented retraining at the frequency required by its procedures. Also, while personal protective equipment was generally available and in good condition, its management could be improved with an inventory listing and preventive maintenance.

The Columbus Processing & Distribution Center is in the Ohio Valley District of the Eastern Area. In fiscal year (FY) 2019, the Postal Service reported 2.1 million late trips nationwide due to contractor failure. From October 1, 2019, to March 31, 2020, the Columbus P&DC had the second highest number (10,948) of originating late trips due to contractor failure for P&DCs. The average time a trip was late was 43 minutes. There were 41 contractors with originating late trips due to contractor failure at the Columbus P&DC. Two contractors accounted for 61 percent of the failures. Our objective was to assess the management of HCR irregularities due to contractor failure at the Columbus P&DC.

As part of our annual audit plan, we audited costs billed to the Tennessee Valley Authority (TVA) by Trans Ash, Inc. (Trans Ash) for construction support services provided under Contract No. 10059. The contract provided that one or more compensation methods may be utilized to complete the work-cost reimbursable, target cost estimate, or fixed price. Our audit objectives were to determine if (1) costs were billed in accordance with the terms and conditions of the contract and (2) tasks were issued using the most cost efficient pricing methodology. Our audit scope included about $34.4 million in costs billed to TVA from May 20, 2015, through November 30, 2018. This included $20.9 million for cost reimbursable projects and $13.5 million for fixed price projects.In summary, we determined:Trans Ash overbilled TVA $1,592,128 on cost reimbursable projects, including (1) $1,312,051 in unapproved subcontractor costs, (2) $32,895 in ineligible fees associated with subcontractor costs, (3) $156,403 in labor and related costs, (4) $42,929 resulting from the use of lump sum pricing when the purchase order provided for a cost reimbursable compensation methodology, (5) $42,000 in temporary living costs, and (6) $5,850 in equipment costs.Trans Ash billed TVA for construction equipment rented from TVA's Equipment Support Services (ESS) group using the Trans Ash equipment rental rates included in the contract's rate schedule instead of billing TVA for the equipment rentals as a direct pass through cost, as required by the contract's terms and conditions. However, due to the process used by TVA to bill Trans Ash for ESS equipment rented, we could not determine the cost impact, if any, of Trans Ash billing ESS equipment using the contract's equipment rental rate schedule.The use of fixed price or unit rate payment terms on projects caused TVA to pay at least $1.6 million more than it would have if cost reimbursable payment terms had been used for those projects. Additionally, we determined the unit rate payment terms used by TVA to compensate Trans Ash were not provided for in the contract's terms and conditions.We also noted several opportunities to improve contract administration by TVA. Specifically, we determined TVA paid an additional $137,190 in noncraft labor costs due to conflicting contract language. In addition, we found (1) TVA could not locate any of the exhibits to the contract, (2) Trans Ash did not submit an electronic billing file to the TVA Office of Inspector General (OIG) in the format and frequency provided for in the contract's terms, and (3) the contract's Order of Precedence clause included inconsistent guidance on which documents took precedence in the event of a conflict.(Summary Only)

Nutritional marasmus (diagnosis code E41) and unspecified severe protein-calorie malnutrition (diagnosis code E43) are two types of severe malnutrition. Previous OIG audits of severe malnutrition found that hospitals had incorrectly billed Medicare by using severe malnutrition diagnosis codes when they should have used codes for other forms of malnutrition or no malnutrition diagnosis code at all. Diagnosis codes E41 and E43 (severe malnutrition diagnosis codes) are each classified as a type of major complication or comorbidity (MCC). Adding MCCs to a Medicare claim can result in a higher Medicare payment.
