Toronto Ravine and Natural Feature Protection Area. Erosion and sediment control (ESC) around Enbridge (EGD) construction area. Worked within the in-water construction time frame. Tree inventory. Construction through a watercourse and a Ravine and Natural Feature Protection area. Construction restraints for the Pan Am games. No outstanding concerns. Restoration was to be completed by the city. EGD worked in conjunction with the city for ESC measures around a watercourse. ESC was installed around EGD construction site. Retained an arborist to assess the trees in the ravine area and determined no harm to trees was expected. Additional pipe was installed to remediate the depth issues of the orginal main.

Enbridge Gas Distribution Inc. 2018 20009039 & 20278826 Area 40 (Bowmanville 10/3/2018 The project consisted of the installation of the gas service to serve a new subdivision. The project crossed a watercourse that was in a fill regulated area for Central Lakes Ontario Conservation Authority. The subdivision development also identified Bobolink Species at Risk habitat in the area. The pipeline was installed via a horizontal directional drill to avoid impacting the watercourse. Erosion and sediment controls were put in place including sediment soxx. The Town of Clarington provided the registration letter for the Bobolink SAR habitat. Town of Clarington identified an impact to Species at Risk habitat (bobolink) as part of the subdivision development and gas service installation. No outstanding concerns The Town registered the activity with the MNRF and provided the confirmation of registartaion to Enbridge. No post-construction issues. CLOCA permit received 26 July 2018.

Site restoration 2. No tree removal 3. Work will be limited to the road allowance 4. No in-water works; watercourse crossing will be completed via HDD 5. Installation of erosion sediment controls around tie-in pits Additional measures: 1. If any SAR are observed within the vicinity during construction, notify Land Services immediately. Watercourse crossings - cross above existing culverts using horizontal directional drilling techniques (HDD). Installation and maintenance of erosion and sediment control measures. Wetlands in vicinity of pipeline route - crossed within existing right-of-way utilizing HDD. Installation and maintenance of erosion and sediment control measures. Woodlots in vicinity of pipeline route - SAR review was conducted. No butternuts within the construction area. No tree removal. Agricultural land - Crossed the site using HDD to maintain access and reduce impact to the surface. Cemetery - A change was made pre-construction to keep the proposed gas main over 10m away from the cemetery. The route was adjusted since the preferred side street was not wide enough to allow the proposed gas main to be installed outside of a 10m buffer. The County of Prescott Russell had concerns with our gas main location through right-of-way in proximity to the wetland. No concerns identified during construction. No outstanding concerns. Talks progressed with that County and the concerns were resolved during the planning stage.

Variance Explanation Additional Details: Shortly before the reinforcement went to Construction, a change in the proposed route was decided upon and permitted. This route change was slightly more complicated to construct and lengthened the proposed pipeline by approximately 80m but increased the separation from a cemetery.
