Trinity’s St. Louis staff bring extensive hands-on experience with Missouri and Illinois environmental permitting and compliance. Since 2001, the office has locally served clients on more than 2,700 projects in a wide range of industries. With in-depth knowledge of the state and federal permitting and compliance processes, we support industrial clients with authorizing capital projects and enforcement negotiations with EPA Regions 5 & 7, the Missouri Department of Natural Resources, and the Illinois Environmental Protection Agency.

Your facility in Missouri deserves a tailored approach—not a one-size-fits-all checklist. Trinity’s regional consulting team understands the specific air, water, waste, safety, and permitting challenges you face right here in St. Louis and across the state.
