Welcome to Trinity Consultants Michigan

Trinity’s Ann Arbor office opened in 2017 with just one air consultant and has grown to include multiple staff members with a wide range of environmental consulting experience. From air services to subsurface investigations and EHS compliance, we support clients with in-depth knowledge of the state and federal programs. We also assist with authorizing capital projects and enforcement negotiations with EPA Region 5 and the Michigan Department of Environment, Great Lakes, and Energy. Our staff is well-prepared to assist with navigating the complex world of environmental compliance.

Michigan - Specific Expertise

Key Service Specifics by State Regulation

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

Our team of consultants provide industry-leading expertise in air quality management, emissions control, and regulatory compliance to help businesses navigate evolving environmental requirements. With increasing scrutiny from the EPA, state, and local agencies, organizations must proactively manage air emissions, permitting, and monitoring to ensure compliance and minimize environmental impact.

Our team of experts provide full-spectrum EHS (Environmental, Health, and Safety) Management services that help organizations achieve regulatory compliance, reduce operational risk, and build more sustainable operations. We support clients across diverse industries in meeting local, state, and federal requirements ranging from air and water regulations to hazardous waste and noise control. With a proactive, strategic approach, we ensure your operations are not only compliant, but also resilient, efficient, and aligned with your business and sustainability goals.

Trinity Consultants offers remedial investigation services to help clients identify and assess the nature and extent of environmental contamination. Our team conducts thorough site characterizations, evaluates potential risks to human health and the environment, and develops data-driven strategies for effective cleanup. By guiding organizations through the regulatory process, they ensure compliance while supporting sustainable and safe site restoration.

Managing chemicals across today’s regulatory landscape requires expertise, vigilance, and a proactive approach to compliance. We help companies meet a wide range of chemical management obligations – from local reporting rules to complex federal programs – while aligning environmental and safety goals. Our chemical compliance services are designed to reduce risk, improve data accuracy, and help clients stay ahead of ever-evolving regulations. Whether you’re tracking toxic substances, managing refrigerants, or filing annual reports, Trinity provides the insight and operational support you need.

We help clients safeguard local water resources and maintain full compliance with water quality regulations. Our water quality services combine deep regulatory knowledge with practical field expertise to support industrial, commercial, and municipal operations nationwide.

Whether you’re managing discharges under the Clean Water Act, responding to local stormwater requirements, or implementing spill prevention measures, our water quality consultants provide strategic guidance and hands-on support to keep your operations aligned with both environmental protection and business goals.

We help organizations navigate the complex regulatory landscape of waste management while aligning waste strategies with sustainability and operational goals. Our services support the entire waste lifecycle, from generation and handling to treatment, disposal, and beneficial reuse. We ensure clients achieve compliance, reduce environmental risk, and capture value from waste streams. With deep expertise in RCRA, TSCA, CERCLA, and industry-specific standards, Trinity’s waste management consultants offer practical, tailored solutions that meet the needs of industrial, commercial, and institutional facilities across the U.S.
