EPA Delegates Chemical Release Program to Missouri
The EPA has approved Missouri's request for partial delegation of the Clean Air Act's Accidental Release Prevention Program. The move grants the state direct oversight authority for covered facilities, increasing compliance complexity for manufacturers operating in the state. This action may signal a broader trend toward state-level regulatory fragmentation.
The partial delegation centers on Section 112(r) of the 1990 Clean Air Act amendments, a program designed to prevent catastrophic chemical accidents. This section requires facilities handling highly hazardous substances to develop a Risk Management Plan (RMP) that includes hazard assessments, prevention programs, and emergency response plans. The focus of Missouri's new authority is agricultural facilities storing 10,000 pounds or more of anhydrous ammonia, a common nitrogen fertilizer. This transfer of oversight is part of a larger trend known as "cooperative federalism," where the EPA delegates implementation and enforcement of federal environmental laws to state agencies. Proponents argue this allows for more tailored approaches to local needs and can increase cost-effectiveness. States like Florida and North Dakota already have partial delegation for this specific program, with North Dakota also overseeing only agricultural ammonia facilities. For manufacturers, this shift can mean navigating a patchwork of state-specific regulations rather than a single federal standard, potentially increasing compliance complexity. Industry groups often favor state-level oversight, believing it can be more attuned to local economic conditions. The Missouri Agribusiness Association, for example, advocates for the business of agriculture and works with state regulators on behalf of its members. Conversely, environmental and community advocates may raise concerns about the consistency and stringency of state-led enforcement. The Missouri Department of Natural Resources (DNR) has previously faced scrutiny from the EPA and environmental groups over its permitting decisions and enforcement actions. In 2021, the EPA found the DNR in violation of the Civil Rights Act for failing to consider the disproportionate impact of pollution on low-income communities of color in its permitting process. The EPA will retain concurrent authority to enforce the program in Missouri and has sole authority for all other regulated chemicals at these agricultural facilities. The move comes as the manufacturing sector faces increasing pressure to manage environmental risks, with the EPA strengthening enforcement in communities disproportionately affected by industrial pollution. This delegation was enabled by Missouri House Bill 3, which authorized the state's Air Conservation Commission to implement and enforce the RMP for agricultural anhydrous ammonia. The state rule establishes annual registration and tonnage fees for facilities to fund the program's implementation by the Department of Natural Resources.
