HB 3652 requires the Railroad Commission of Texas to conduct a study on the feasibility of creating a strategic fuel reserve for gas and petroleum products. The study must examine the viability of establishing, operating, and maintaining a reserve, determine the most appropriate locations for facilities, identify the roles of state and local entities in managing the reserve, assess the necessary minimum capacity, define the circumstances under which fuel should be distributed, and estimate costs for purchasing, constructing, operating, and maintaining storage facilities. The commission must submit a report on its findings and legislative recommendations to the governor, lieutenant governor, speaker of the house, and each legislator by September 30, 2026. The bill expires on January 1, 2027.
