Louisiana

From New Source Review and Title V to expedited permitting authorizations such as Regulatory Permits, Authorization to Construct and Operate, and Case-by-Case Insignificant Activities, we navigate Louisiana Department of Environmental Quality (LDEQ) air quality permitting to accelerate approvals, minimize risk, and keep projects compliant across Louisiana’s fast-growing industrial hubs.

Trinity’s Louisiana offices specialize in Louisiana Pollutant Discharge Elimination System (LPDES) permitting as well as Spill, Prevention, Control, and Countermeasure (SPCC) and Stormwater Pollution Prevention Plans (SWPPP). We also assist with Army Corps (Section 404) permitting and best management practice implementation.

Louisiana-focused air dispersion modeling that meets LDEQ requirements—demonstrating NAAQS and PSD Increment compliance as well as Louisiana Toxic Air Pollutant Ambient Air Standard compliance to streamline NSR/PSD and Title V permitting across the state.

We deliver Louisiana-specific environmental reporting—preparing and filing LDEQ-compliant air, water, and waste submittals—so your operations meet state and federal deadlines with confidence. Trinity can support your annual Emissions Reporting & Inventory Center (ERIC) submittals, Tier II, TRI, annual hazardous waste report, GHG, stormwater reporting, as well as Title V Permit Annual Compliance Certification and Semi-Annual Monitoring Reports.
