SUPPLEMENTARY INFORMATION:

FRA issued this Directive under 49 CFR 180.509(b)(4) to all owners of DOT specification 111 general purpose tank cars based on its finding that as a result of non-conforming welding practices, DOT-111 tank cars built by American Railcar Industries, Inc. (ARI) or ACF Industries, LLC (ACF) between 2009 and 2015 to the ARI or ACF 300 stub sill design and equipped with a two-piece cast sump and bottom outlet valve skid may be in an unsafe operating condition and could result in the release of hazardous materials. As a result of the identified non-conforming welding practices, these cars may have substantial weld defects at the sump and BOV skid groove attachment welds, potentially affecting each tank's ability to retain its contents during transportation. FRA issued the Directive to ensure public safety, ensure compliance with the applicable Federal regulations governing the safe movement of hazardous materials by rail, and ensure the railworthiness of the tank cars. The full text of the Directive is available on FRA's Web site at www.fra.gov by searching for RWD No. 2016-01.
