The RCORP Authorization Act establishes a formal Rural Communities Opioid Response Program within the federal government to combat opioid and substance use disorders in rural areas. The bill authorizes the Health Resources and Services Administration to award grants and cooperative agreements to states, Indian tribes, state rural health offices, and other eligible organizations to fund prevention, treatment, and recovery services in rural communities. Recipients can use these funds for planning, implementing evidence-based treatment models, responding to emerging public health threats, and technical assistance—but not for purchasing or improving real property. The program is authorized to receive $165 million annually from fiscal years 2026 through 2030, with individual grants lasting up to five years.
