Enbridge Gas Inc. Enbridge Gas Distribution Inc. 2015 N/A 1028042 72 431821 596221 Yes The City of Mississauga is replacing the bridge and Enbridge (EGD) had to relocate the existing main underneath the Credit River crossing with additional pipe installed. Through a desktop study bedrock was identified in the area. SAR habitats were identified in the area. Mississauga community park nearby. EGD obtained an extension from the MNRF Notice of Activity (NOA) for construction outside the SAR time window. No N/A N/A 9/8/2015 No N/A N/A N/A Larger scope of work Credit Valley Conservation Authority Permit (CVCA), MNRF - NOA, Mississauga's parks agreement, Tree assessment, Migratory Bird Nest Surveys N/A N/A HDD underneath the Credit River was used to minimize impact to SAR. EGD consulted with the MNRF on mitigation measures for the SAR and also with the city regarding the proximity of the park. A tree assessment was done for SAR. Migratory Nest surveys were performed before any construction clearing occurred. ESC was in place for construction activities. HDD contingency plan was in place.

Erosion and Sediment Control measures were put in place - Siltsoxx and Ditch Checks used to mitigate erosion impact. In compliance with the Migratory Birds Act, a nest sweep was completed prior to removing vegetation. A licensed arborist was sourced to provide an arborist report and outline the Tree Protection Zones within the work area. No outstanding concerns The project was within a fill regulated area for the Toronto Region Conservation Authority and within a Ravine and Natural Feature Protection Zone for the city of Toronto.
