Clean Up the River Environment CURE (Clean Up the River Environment), a Montevideo-based rural organization, along with partner organizations in Iowa, Nebraska, North Dakota, and South Dakota, are calling on the Pipeline and Hazardous Materials Safety Administration (PHMSA) to advise states not to permit any new CO2 pipelines until regulations for high pressure hazardous liquid CO2 pipelines from PHMSA are complete. Due to the unknowns around CO2 pipelines, CURE and Upper Midwest partner organizations, also request that PHMSA hold a public meeting on both the research questions and knowledge gaps that need to be addressed for a rigorous CO2 rulemaking and what CO2 regulations should contain.
