TRSPA SWP Event Based Areas
Polygon layer displaying Event Based Areas (EBA) in the Toronto and Region Source Protection Area (TRSPA). An EBA is an area where a specific activity exists or could exist in the future, and where a release of contaminants could pose a threat to drinking water by being transported to a surface water intake during an extreme event (e.g. storms, droughts, etc.). The event-based area is the area where such activities can be identified as significant drinking water threats under the event-based approach, and where policies apply as set out in the Source Protection Plan.
Entity Name: SWP Event Based Area
Table Name: SWP_EVENT_BASED_AREA_FT
An area within a watershed where a spill could pollute the drinking water supply because of sanitary sewers, sewage treatment plants or pipelines that are close to rivers, streams or other water bodies.
