In the 48th Annual Critical Review presented at the Hartford Annual Conference and Exhibit, Dr. H. Christopher Frey covered the major advances in engine design, control technologies, and fuels that have made it possible to reduce emissions and fuel use despite sustained growth in miles travelled. A distinguished panel provided viewpoints ranging from health, industry, monitoring, and the environment.

This webinar will review and expand upon this important topic and provide updates from Dr. Frey and four expert panelists. Learn from this diverse group as they further review and explore vehicle energy usage and emissions that affect us all.

Ontario ECA (Air) Update: Ministry's Phasing in of Schedule 3 for All Facilities Starts February 1st, 2019

Phase-in of Schedule 3 Standards

Schedule 3 standards will apply to all facilities as of February 1st, 2020, and the Reg346 model will no longer be an approved dispersion model under O.Reg.419/05.

However, as of February 1st, 2019, all ECA applications must already include ESDM reports showing compliance with Schedule 3 standards and using SCREEN3, AERMOD, or other non-regulatory model with Ministry s7(1) approval (except Reg346).

Applications will be returned if Reg346 is used, or if AERMOD or SCREEN3 are used to demonstrate compliance with a Schedule 2 standard.

Amendments to Ontario Regulation 455/09 and creation of a new services documents regulation under the Toxics Reduction Act, 2009

On April 24, 2018, the MOECC posted a decision on when facilities have to review their toxic reduction plans.  This will help to align the first two plan reviews with federal timelines and ensure facilities plan and report on current and relevant toxic substances. The MOECC also made a new regulation to provide more options to serve documents making it consistent with other regulations.
