Welcome to Trinity Consultants Louisiana

Trinity staff bring extensive hands-on experience with environmental permitting and compliance in Louisiana. Since 1992, Trinity’s Baton Rouge, Louisiana office has locally served clients on more than 2,000 projects in a wide range of industries. With in-depth knowledge of the local and federal permitting and compliance requirements, we support industrial clients by providing permitting and compliance guidance related to authorizing capital projects, commissioning, routine operations, and enforcement negotiations in Louisiana.

Our local multimedia environmental expertise helped lead Trinity’s transition from our early origins as a firm focused on air quality to a full-service EHS consulting firm.

We maintain active relationships with the Louisiana Department of Environmental Quality (LDEQ) and the Operating Permits Workgroup, the Louisiana Chapter of the Air & Waste Management Association (AWMA), prominent environmental attorneys, and key trade associations representing the client industries that we serve. Whether it’s permitting, compliance, enforcement support, negotiations with LDEQ or EPA Region 6, or systems and tools to streamline EHS performance, our New Orleans team has the experience and expertise to assist.
