Confidential Client – Air Pollution Control

Markets
Overview
A global manufacturer faced growing production demand at one of its Massachusetts facilities. Two processes at the facility needed expanded equipment and operating capacity. To speed the air permitting necessary to the expansion, the manufacturer committed to installation of a regenerative thermal oxidizer to control volatile organic compounds and hazardous air pollutants. The project included upgrades to manufacturing tools with tie ins to the air pollution control.
Contribution
Epsilon Associates led the state air permitting for the project by preparing a non-major Comprehensive Plan Application (nmCPA), a type of air quality permit, for the Massachusetts Department of Environmental Protection (MassDEP). The process, which started in 2022 and will result in permit issuance in 2023, involved conducting screening level air dispersion modeling to determine optimal air pollution control equipment stack height for optimal dispersion, and to mitigate any potential risk of air pollution affecting the surrounding community.
Epsilon additionally assisted in the procurement of the regenerative thermal oxidizer, including development of technical specifications, interaction with vendors during the procurement process, conduct of representative reference site visits, and lifecycle cost analyses.

Achievement
The upgraded infrastructure, which Epsilon provided permitting assistance for, is set to significantly reduce the site's facility-wide air emissions, which will aid in the company's wider environmental goals.
