Featured Project:

Trinity's Minneapolis office recently led a multi-office response to assist a lime manufacturer in revising an New Source Review (NSR) permit to allow greater operational flexibility in the use of raw materials. Trinity's work included reviewing source testing reports, preparing an air toxics emissions and modeling analysis, running near-field and Class I impact analyses, preparing an NSR permit application, and various agency negotiations. The project resulted a revised NSR permit, including changes to several Best Available Control Technology (BACT) limits that provided the client greater operational and raw material flexibility while maintaining existing pollution controls and limiting additional testing requirements. Despite a very challenging regulatory environment, the project timeline from the beginning of our engagement to the issuance of a revised permit was less than 12 months.
