On behalf of the Interested Parties for Hazardous Materials Transportation (“Interested Parties”)[1], we are writing today in support of efforts to enhance the efficiency and effectiveness of government while also ensuring the continued safe and efficient transportation of hazardous materials. In particular, we seek to highlight the critical functions of personnel who oversee the safe transport of hazardous materials within the Department of Transportation, particularly at the Pipeline and Hazardous Materials Safety Administration (PHMSA).
