Earthjustice, on behalf of Sierra Club and ForestEthics, petitions the U.S. Department of Transportation (DOT) to ban legacy DOT-111 tank cars for transporting highly flammable crude oil. The petition argues that these cars pose an "unacceptable public risk" due to high failure rates in derailments, citing disasters in Lac Mégantic, Aliceville, and Casselton. While the DOT has initiated rulemaking and issued operational emergency orders, the petitioners contend these actions are insufficient and too slow to address the imminent hazard. They highlight that Canada has already implemented bans and surcharges on these cars, which may inadvertently push the most dangerous tank cars into the U.S. fleet. The document advocates for an immediate emergency order to bridge the gap until a formal rulemaking process establishes more robust safety standards, such as the CPC-1232 specifications or newer designs.

The report alleges that the NRC has failed to enforce 10 CFR 50.46, allowing 68 of 103 U.S. nuclear reactors to operate with a known vulnerability to containment sump clogging. This issue, which can lead to core meltdown and containment failure during a loss-of-coolant accident (LOCA), has been resolved in dozens of PWRs globally but remains unaddressed in the U.S. The author contends that the NRC selectively uses risk-based probability arguments to justify inaction while ignoring its own regulations and the evidence provided by pseudo-plant-specific analyses from Los Alamos National Laboratory. The report calls for Congressional hearings to reform the NRC's enforcement and resolution processes for generic safety issues.
