Full Environmental Permitting & Ongoing Compliance Support


YESCo Power, a Division of Yankee Energy Services Company, developed a 7 MW on-site cogeneration project for the Southbridge Business Center (formerly American Optical) near the center of the Town of Southbridge, Massachusetts. The project consisted of five gas-fired reciprocating internal combustion engines and two gas-fired boilers for supplemental steam. Tech Environmental provided a detailed permitting feasibility and regulatory strategic planning analysis for the facility and followed up with full environmental permitting for the project.

After the plant began operations in the spring of 2001, Tech Environmental provided operational sound level monitoring to demonstrate compliance with air permit conditions and the State Noise Regulation. Air permitting services included BACT determinations, air dispersion modeling, emissions netting, and the Title V Operating Permit Application.

Tech continues to provide support to the plant, assisting with the preparation of semi-annual and annual reporting requirements. Reporting assistance has included the annual Source Registration and greenhouse gas emission reports for the MassDEP and the annual greenhouse gas emission report for the EPA.
