TRC had its origins with the Travelers Weather Research Center, an affiliate of the Travelers Insurance Company, formed in response to significant property losses from severe storms. As one of the country’s first privately owned weather research centers, we pioneered the use of sophisticated statistical methods, mathematical models, and early computers to significantly improve weather forecasting techniques. As the newly formed TRC, modelers led the way in developing methods to assess air quality outdoors.



Travelers formed a wholly owned subsidiary, The Travelers Research Corporation, which folded in the research segments of the Weather Research Center and added staff in anticipation of forthcoming federal regulations controlling air quality. As one of the country’s first privately owned weather research centers, it pioneered the use of sophisticated statistical methods, mathematical models and early computers to significantly improve weather forecasting techniques.



Under Environmental Protection Agency (EPA) sponsorship, TRC conducted the first major study of the relationships between outdoor and indoor air quality.

The Research Corporation of New England, also known as TRC, was incorporated in the State of Connecticut. We performed meteorological work for the government and industry, including air dispersion modeling, stack sampling and air pollution prevention.



The 1970s were the formative years for the environmental business as public awareness grew and numerous laws were enacted. TRC developed practices in atmospheric studies, air quality monitoring, air pollution control engineering, and ground water studies, forming our foundation as a full-service environmental business. Among other innovations, we developed measurement standards for fugitive emissions and ventilation standards for schools and hospitals.

TRC was acquired by VAST, Inc., a publicly traded company involved primarily in oceanographic and sonar buoy testing for the U.S. Navy. As the environmental research unit with capabilities in pollution control, TRC was VAST’s fastest growing subsidiary with projects including a task order contract for EPA’s Northeast and Caribbean areas to determine long-range ecological effects of oil spills, and a contract for the Connecticut Department of Transportation providing assistance in evaluating implications of proposed transportation plans.


VAST lost its Navy contract, and TRC remained profitable and continued to grow.



VAST closed operations, transferred assets to TRC, changed its name to TRC and reported net service revenue of $3 million. TRC produced its first Annual Report under its own name, replacing the cover photos of Navy subs at sea with rubber-booted scientists ankle-deep in a stream performing a biological impact study.



TRC won the contract from Electric Power Research Institute to validate mathematical models vital to electric utilities for heated pollutants from tall stacks.



The company managed the monitoring program and sampled for metals, organics, pesticides and other pollutants at Love Canal, the site that led to the initiation of EPA’s Superfund Program. With this experience, TRC’s hazardous waste experts designed remedial strategies for some of the first Superfund cleanups for Fortune 500 clients.


TRC developed an assessment sampler for measuring industrial fugitive emissions.



The 1980s were a transformational decade for TRC as our company began to build its specialty of providing services to utilities. The EPA used TRC data to quantify acid rain and to begin climate change studies. TRC’s air quality monitoring business expanded, including contracts with the EPA to develop industry-specific emission standards and emission test methods. TRC also created an indoor air quality business practice and built expertise in monitoring and managing asbestos and other hazardous materials.


TRC acquired the assets of one of the first environmental companies in the US, GCA Technology Division, which doubled the size of TRC and brought the firm a key position in the Massachusetts marketplace.



TRC won an open-order $2.3M EPA contract to support environmental planning and policy activities.

TRC was commissioned by the EPA to expand the scope of data management to support safe drinking water and hazardous waste control programs.


Under contract with the EPA and the Air Force, TRC developed information systems to monitor environmental compliance.


Detroit Edison awarded TRC an $860,000 meteorological and air quality monitoring contract.


Expanding westward, TRC opened a new office in Denver, CO to support the mining industry. Using extensive knowledge of particulate matter and materials damage, we helped to reset the EPA standard of large particles in and around mines.


TRC opened its San Diego, CA office, establishing a West Coast presence.


With larger contracts and more recognition, TRC’s gross revenues broke the $10 million mark and reached $40 million by the end of the decade.

American Stock Exchange


TRC was listed on the American Stock Exchange.


We designed and implemented the Aerometric Information Retrieval System (AIRS), a consolidated database of all industrial emission and compliance data for the EPA. This system continues to be used by EPA headquarters, all 10 EPA regions, 50 states, and trust territories.



The 1990s was a decade of significant growth for the company with gross revenue growing to $78 million. As a national leader in air quality consulting, our growth was fueled by the Clean Air Act Amendments of 1990 as we won 52 master services agreements for Clean Air Act Amendment compliance projects with companies such as GM, AETNA, Exxon, 3M, and GE


The Company becomes the first air pollution engineering company listed on NYSE (TRR).

Columbia Shuttle


TRC MIE’s MINRAM air monitor was used on the Columbia Shuttle.


We developed software to track and report air emissions to facilitate Title V permit applications.


We launched a cultural resources division.


TRC received a five-year $11 million contract from the EPA to operate and maintain a human studies facility in North Carolina.


TRC launched our ground-breaking environmental liability transfer program, Exit Strategy®, which pioneered the concept of fixed-price environmental liability transfers for contaminated sites.

Clean Air


Partnering with a law firm, our growing air pollution permitting staff wrote a guidebook on the Clean Air Act Amendments to advise industry management and decision makers.



TRC expanded services in power delivery, engineering, procurement, construction, infrastructure design and construction management. Today, our experts are working to address some of our nation’s most challenging issues, including global climate change and energy independence.
