________________________________________ June 2, 1997 ________________________________________ GSBCA 13652-TRAV In the Matter of ROBERT T. WOLAK Robert T. Wolak, Nazareth, PA, Claimant. Bobby A. Derrick, Acting Director, Finance and Accounting Systems Transition, Indianapolis, IN, appearing for Department of Defense. BORWICK, Board Judge. Robert T. Wolak (claimant), a Department of the Army civilian employee, filed a claim at the General Accounting Office challenging the Department of the Army's determination that claimant owed $34.50 (plus a $15 service charge for overpayment) for alleged excess mileage travel. The Army determined that claimant drove too many miles, compared to the mileage shown by AR 55-60 (1982), the Official Tables of Distance (OTD) published by the Department of the Army. For the reasons that follow, we conclude that the agency determination was correct. Pursuant to the agency's authorization in June of 1994, claimant traveled between his residence in Nazareth, Pennsylvania and Vint Hill Farms, Virginia, in his privately owned vehicle (POV). After completion of his trip, he submitted a travel voucher claiming 791 miles of travel, based on the mileage shown on his odometer. The Department of Defense Joint Civilian Personnel Travel Regulations in effect at the time claimant traveled provided that when transportation is by POV, distances will be as determined from odometer readings. Such distances will be used as a basis for reimbursement "unless there is a substantial and unexplained deviation from the [OTD.]" Whenever the deviation exceeds three percent of the distance shown in the OTD or ten miles, whichever is the greater, an explanation will be required together with the approval of the travel approving official. JTR C4658. The Army allowed reimbursement for mileage traveled presumably as shown by the odometer reading for those segments of claimant's trip where the OTD was silent. Claimant does not challenge the Army's determination of the miles traveled on these segments of his trip. The OTD, however, shows the distance for certain segments to be 115 miles less (including the three percent variance allowance) than the distance claimed for those segments. At the time of claimant's travel, the POV mileage rate was $.30 per mile; the Army determined that claimant owed a refund of $34.50 from travel payments, plus a $15 processing fee. Claimant maintains that the Government is not entitled to the refund because the OTD is in error. He offers the mileage shown on the AAA Trip Planner as proof. For example, claimant maintains the AAA Trip Planner mileage shows the distance between Tobyhanna, Pennsylvaia and Warrenton, Virginia to be 285.8 miles, while the OTD lists the distance as 266 miles. While the official approving the travel approved the excess mileage, claimant did not explain the mileage discrepancy, except to maintain the OTD was erroneous. The GAO held that the question of what routes are to be used in establishing the distances in the OTD is a matter solely within the discretion of the agency, and the GAO would not question the legality or correctness of the administrative method used in establishing the highway distances. Ronald W. Hameline, B-130527 (Apr. 3, 1974). We adopt this rule. The agency is entitled to the refund. Absent explanation, such as inclement weather or unavoidable detours, Donald R. Ramsey, B-162662 (Nov. 8, 1967), the agency does not abuse its discretion by insisting that reimbursement be limited to the distance shown on the OTD, plus allowable variance. See James Jackson, GSBCA 13897- TRAV (May 15, 1997)(applying similar provision in Federal Travel Regulation); Constantine Bolaries, B-206646 (Apr. 3, 1984); James H. Lewis, B-194254 (Jun. 18, 1979). Claimant does not challenge the $15 service charge and we do not consider that matter here. As to the mileage, claimant has provided no explanation why we should accept his POV mileage as against the OTD distances. We note significant discrepancies between the mileage claimant states he drove, and the mileage as shown by the OTD. In one instance, he seeks reimbursement for 320 alleged driving miles between Tobyhanna, Pennsylvania and Vint Hill Farms, Virginia, when the OTD shows a distance of 266 miles between those points, a difference of 54 miles. The AAA Trip Planner routing and mileage does not explain this discrepancy. There is a similar large, unexplained discrepancy for the return leg of his trip from Vint Hill Farms, Virginia to Old Forge, Pennsylvania. __________________________ ANTHONY S. BORWICK Board Judge
