In Part 4 of this 4-part BWON Webinar Series, Trihydro will share lessons learned from various program audits we have performed over the years. We'll share useful rules of thumb, common audit findings, commonly missed waste streams, how to address adjacent facilities in the BWON program, what to do with maintenance waste and spills, and the importance of annual review and management of change. We will also review past Environmental Protection Agency enforcement actions and how current technology (e.g. Infrared cameras, fenceline monitoring) can play an important role in maintaining a compliant BWON program.
