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.
