Welcome to Trinity Consultants Pennsylvania

Trinity | Environmental Consulting – Trinity’s Pittsburgh and Philadelphia offices bring extensive hands-on experience with environmental permitting and compliance for a wide range of industries in Pennsylvania. Our offices are deeply familiar with the intricacies of the Pennsylvania Department of Environmental Protection (PADEP), Philadelphia Air Management Services (AMS), Delaware Natural Resources and Environmental Control (DNREC), Allegheny County Health Department (ACHD), and USEPA Region 3. Both offices are well equipped to efficiently address any environmental permitting, or compliance challenges your Pennsylvania or Delaware facility may face.

Trinity’s Built Environment pillar opened its Philadelphia office at 1700 Market Street in 2026, co-locating its acoustics and technology design team. Now 25 staff strong, the office supports a growing regional portfolio including Jefferson Health’s Honickman Center, the SK pharmteco campus in King of Prussia, and Longwood Gardens.

Pennsylvania - Specific Expertise

Key Service Specifics by State Regulation

Trinity staff bring extensive hands-on knowledge of Pennsylvania environmental permitting and compliance.

Our team helps facilities achieve compliance with federal, Pennsylvania, and Delaware air quality regulations, including PADEP and DNREC operating permits (Title V and State-Only) and pre-construction permits (Plan Approvals and Regulation 1102). Our experts ensure compliance with Philadelphia’s Air Management Regulation VI, Allegheny County Article XXI and DNREC modeling requirements, addressing toxic air contaminants and local emission standards. From air dispersion modeling to permitting and compliance strategies, we simplify complex requirements to reduce risk and maintain flexible operations.

Our team provides support for Tier II, TRI, emission inventories, hazardous waste, Title V certifications, NSPS/NESHAP reports, and more. From data collection to submission, we streamline processes, reduce risk, and ensure compliance so you can focus on your core operations while staying ahead of regulatory deadlines.

We offer comprehensive EHS management services that strengthen compliance, reduce risk, and drive operational excellence. We deliver solutions including gap analysis, system development, training, EHS auditing, ISO certification readiness, and innovative digital solutions helping organizations implement practical strategies that improve efficiency and build stakeholder confidence.

We empower organizations to achieve sustainability objectives with practical, results-driven solutions. From quantifying and reporting Scope 1, 2, and 3 emissions to decarbonization and strategic planning, we turn complex requirements into measurable success.

We help clients navigate complex waste regulations while aligning strategies with operational goals. Our team supports the entire waste lifecycle from generation and handling to treatment, disposal, and beneficial reuse, ensuring compliance and reducing environmental risk. In Pennsylvania, we guide businesses through the DEP Residual Waste Program requirements, including permitting, reporting, and beneficial use opportunities to minimize liability and capture value from waste streams.

Our offices provide end-to-end water quality solutions that help organizations maintain compliance with federal, state, and local regulations while protecting vital water resources. Services include permitting (No Exposure, General Permits and NPDES), stormwater and spill prevention planning, and strategic guidance to align environmental performance with operational goals.
