Toxic Release Inventory (TRI) Reporting

Ensure Accurate and Timely TRI Reporting with Expert Compliance Support

The U.S. EPA’s Toxics Release Inventory (TRI) program requires facilities that meet specific applicability criteria to track and report releases of listed chemicals on an annual basis. With over 800 listed chemicals and chemical categories and complex reporting requirements, maintaining compliance can be challenging. Drawing on decades of experience, advanced analytical tools, and proven methodologies, we have supported thousands of facilities in navigating TRI requirements with accuracy while minimizing compliance risks.

See how Trinity streamlines the TRI reporting process to ensure compliance, accuracy, and reduced liability.

We conduct chemical-by-chemical threshold analyses to determine reporting applicability, ensuring that facilities understand their obligations under TRI.

Our team develops detailed release, treatment, and transfer estimates for each chemical, tailored to the unique processes and operating conditions of every site.

Trinity leverages custom chemical release tracking and reporting tools designed to fit site complexity and client budgets, improving efficiency and reliability.

We audit past TRI submissions for accuracy, correct errors as needed, and support EPA’s eDisclosure process for reporting past violations.

Our experts deliver both public and custom TRI training courses designed to enhance staff capability and ensure sustained compliance.

We provide risk assessment modeling, review vendor liability for waste streams, and assist in implementing pollution prevention practices that minimize future reporting burdens.

High Stakes Capital Projects

In this issue of EHS Quarterly, we examine how environmental consulting plays a pivotal role in turning regulatory challenges into project advantages. By embedding proactive environmental management and permitting strategies early in the capital project lifecycle, organizations can reduce risk, improve outcomes, and create measurable value.

Toxic Release Inventory (TRI) Reporting FAQs

The TRI is an EPA program established under the Emergency Planning and Community Right-to-Know Act (EPCRA) and codified under 40 CFR Part 372. It requires certain facilities to report annual releases and waste management activities for designated toxic chemicals known to cause cancer, chronic health effects, or environmental harm.

Facilities with 10 or more full-time employees that operate in a covered industry sector and manufacture, process, or otherwise use listed TRI chemicals above applicable reporting thresholds are required to submit annual reports. These requirements apply to a broad range of industries, including general manufacturing, chemical manufacturing, metal fabrication, oil and gas production, electric power generation, mining, hazardous waste treatment, and semiconductor and electronics manufacturing.

Facilities must report core site details (including facility identifiers, technical/public contacts, and parent company information) and, for each TRI-listed chemical above threshold, the maximum quantity on-site during the year. They must also quantify and report all environmental releases and waste management activities, including on-site air, water, land, and underground injection releases, as well as amounts managed as waste through recycling/beneficial reuse, on-site treatment, and energy recovery, plus any off-site transfers for recycling, treatment, energy recovery, or disposal.

TRI reports are due annually by July 1st for the previous reporting year. Reports must be submitted to both the EPA and the applicable state agency.

Trinity supports clients across the full TRI lifecycle by confirming applicability and thresholds, developing defensible release and waste‐management calculations, auditing prior filings to identify and correct gaps, and preparing and submitting Form R/Form A reports. We also deliver practical training for site teams and design pollution prevention and source-reduction strategies that lower TRI quantities over time. The result is reduced regulatory risk, smoother year-to-year compliance, and stronger overall environmental performance.
