Further guidance on how the data and information generated from verified laboratory testing of OGS technologies should be interpreted and factored into regulatory agency approvals and procurement decisions for stormwater management is provided in this publicly available specification [https://sustainabletechnologies.ca/app/uploads/2023/07/SETV-Guidance-PAS-2023-07-27-English.pdf '''The Canadian Procedure for Field Testing of Stormwater Filtration Manufactured Treatment Devices'''], developed by TRCA and the [https://www.scc.ca/ Standards Council of Canada] that addresses both OGS and Filtration MTDs.
