Tora developed the permitting strategy and air applications for over 30 renewable natural gas (RNG) facilities across six states. These projects included emissions calculations, regulatory applicability reviews, and minor NSR permitting for digestion, flares, utilities, fugitive components, and truck traffic.

Tora documented when manure handling operations were non-applicable to air permits, managed compliance for facilities in non-attainment areas, and supported fleet-wide operating flexibility. Our team also created custom compliance plans, conducted site visits to all digester and injection sites, and worked closely with the client’s staff to align practices with regulatory standards.
