8.0 DISCUSSION AND RECOMMENDATIONS 8.1 General Vegetation Recommendations General mitigation measures to avoid or reduce the potential environmental effects on vegetation during construction and operation of the Project are provided in the Project-specific EPPs (Appendix 1 of the ESA) [Filing IDs A4E6X1 to A4E6X4]. See Appendix G in Appendix 1A of the ESA [Filing IDs A4E6X1 to A4E6X4] for the weed control methods that will be implemented during construction and clean-up activities for the Project.

8.2 Recommended Supplemental Surveys Access was not available on some land parcels at the time of the supplemental vegetation surveys in late June 2014 and August 2014. In addition, several reroutes have been made following the supplemental vegetation surveys. As a result, the supplemental vegetation surveys did not include all areas identified as having high potential to support rare plants.

For the above-listed reasons, the following actions are recommended for the Project.

• Conduct supplemental early and late-season vegetation surveys during the 2015 growing season, along selected areas of the Footprint that were revised since completion of the late June 2014 and August 2014 supplemental vegetation surveys (i.e., reroutes with rare plant habitat potential from SKP 187.3 to SKP 191.3, SKP 238.8 to SKP 239.2, SKP 315.4 to SKP 316.7, SKP 324.6 to SKP 325.0, SKP 363.3 to SKP 363.7, SKP 425.8 to SKP 427.0, SKP 447.5 to SKP 448.5, SKP 505.6 to SKP 506.4, SKP 517.7 to SKP 520.4, SKP 550.0 to SKP 550.2, SKP 599.5 to SKP 599.7, SKP 603.9 to SKP 604.1, SKP 659.8 to SKP 660.5, SKP 710.2 to SKP 742.9, SKP 869.9 to SKP 870.5, SKP 894.3 to SKP 895.1, SKP 968.9 to SKP 969.0, SKP 969.4 to SKP 980.7, SKP 1002.9 to SKP 1016.0, SKP 1018.7 to SKP 1019.0, SKP 1023.8 to SKP 1025.3, SKP 1094.3 to SKP 1096.2, SKP 1125.9 to SKP 1127.2, SKP 1148.6 to SKP 1149.6, SKP 1181.6 to SKP 1182.5, SKP 1226.2 to SKP 1234.2, SKP 1241.7 to SKP 1250.7 and SKP 1250.7 to SKP 1254.3 (see Table 4) and along any other potential reroutes that are confirmed prior to the end of the 2015 growing season, where warranted after further review).

• Conduct supplemental vegetation surveys during the 2015 growing season along select areas of the Footprint where access was not previously granted (i.e., SKP 286.0 to SKP 289.0, SKP 402.0 to SKP 407.0, SKP 436.0 to SKP 437.0, SKP 640.0 to SKP 642.0, SKP 661.0 to SKP 663.0, SKP 975.0 to SKP 977.0, SKP 1012.0 to SKP 1022.0 and SKP 1087.0 to SKP 1088.0).

• In the event that route changes occur after the 2015 supplemental vegetation surveys have been conducted, conduct further review to determine whether additional vegetation surveys are warranted prior to construction.

8.3 Rare Plant and Rare Ecological Community Recommendations In accordance with the spirit and intent of the Environmental Assessment Best Practice Guide for Wildlife at Risk in (Lynch-Stewart 2004), site-specific mitigation measures have been developed for all occurrences of rare plant and rare ecological communities observed along the Footprint. These recommended mitigation measures are intended to eliminate or reduce the potential construction-related effects on occurrences of rare plants and rare ecological communities observed along the Footprint.

Recommended site-specific mitigation measures for rare plants and rare ecological communities that were observed during the supplemental vegetation surveys are summarized in Table 13. A complete list of site-specific mitigation measures (including site-specific mitigation confirmed based on the future 2015 supplemental vegetation surveys) will be provided in the updated EPPs and Environmental Alignment Sheet Packages to be filed with the NEB prior to construction. See Section 9 of the ESA [Filing ID A4E6X0] for information regarding the Post-Construction Environmental Monitoring (PCEM) Program for rare plant and rare ecological community occurrences.

Slender yellow-cress is ranked S1 in Saskatchewan. An S1 rank indicates that the species is considered critically imperilled (typically five or fewer occurrences) because of some biological factor(s) (NatureServe 2014b). As this population is ranked S1, avoidance of the population via leaving a gap in the spoil pile in order to narrow the right-of-way is the preferred and recommended mitigation.

Note that the populations are located perpendicular to the Footprint. They will likely 14U 500103E 5480535N be avoided by a road bore, except for access ramps from the road. Therefore, 14U 500104E 5480341N mitigation method 9 is the preferred method to protect the populations from disturbance. Notes: A See the footnotes of Appendix B in Appendix 9 of the ESA [Filing IDs A4E7D1 to A4E7D5] for definitions of rarity ranks. B All SKP locations are approximate. C The construction right-of-way Footprint will typically be 45 m wide. D Mitigation measures recommended for implementation during the Planning Phase of the Project include: 1) If feasible, schedule construction to occur after the seed set period to enhance the survival of the population. 2) Obtain agreement with landowners regarding transplant receiving sites, where identified on private lands. Receiving sites are typically placed adjacent to the proposed Footprint, where appropriate habitat can be found near the construction right-of-way. E Mitigation measures recommended for implementation during the Construction Phase of the Project include: 3) Consider extending the road bore to avoid the rare plant population and, if applicable, the associated wetland. 4) Leave a gap in the spoil pile within a 10 m radius of this population and flag/stake with flagging tape and/or lathe as appropriate around the occurrence area to avoid accidental encroachment. 5A) Narrow the construction right-of-way, to the extent feasible, in the vicinity of the rare plant population or rare ecological community. 5B) Narrow the temporary workspace, to the extent feasible, in the vicinity of the rare plant population or rare ecological community. 6A) Fence the edge of the construction right-of-way nearest to the population to avoid accidental encroachment. 6B) Flag the edge of the construction right-of-way nearest to the population to avoid accidental encroachment. 6C) Flag the edge of the shoo-fly nearest to the population to avoid accidental encroachment. 7) Avoid taking extra temporary workspace in this area. 8) If feasible, utilize the proposed right-of-way for travel. 9) Construct a temporary travel surface using appropriate protective material (e.g., subsoil and geotextile or matting) in order to reduce soil and vegetation disturbance within the population extent. If matting is expected to be needed for more than one season and will not be in constant use during this time (e.g., matting installed during winter will remain until the following winter), matting should be removed prior to the growing season and replaced immediately before construction activities resume. 10) Transplant the population (or a portion of the population) expected to be affected by construction to an appropriate habitat outside of the Footprint, during the growing season prior to construction. 11) Salvage topsoil in the vicinity of this location, where grading is necessary. Salvage topsoil to a depth of up to 15 cm from within a 10 m radius of this location. Isolate topsoil from other spoil piles and identify by labeled stakes or flags. Redistribute salvaged topsoil over the construction right-of-way at the location from which it was salvaged. 12) Pay particular attention to restoring pre-construction contours following construction near this population to ensure site microtopography and hydrology are maintained. F Mitigation measures recommended for implementation during the Post-Construction/Operation Phase of the Project include: 13) Monitor the effectiveness of implemented mitigation measures during rare plant PCEM. 14) Avoid blanket use of herbicides within 30 m of, or between the range of, the provided UTM coordinates. Target spraying, wicking, mowing or hand-picking are acceptable weed control measures in proximity to rare plants and rare ecological communities and may be important to prevent competition with invasive plant species.

9.0 SUMMARY The land use crossed by the reroutes does not differ greatly from the land use crossed by the original Line 3 replacement pipeline route. The reroute from SKP 517.7 to SKP 520.4, from SKP 599.5 to SKP 599.7, from SKP 969.4 to SKP 980.7 and from SKP 1002.9 to SKP 1016.0 avoids several populations of previously observed rare plants, however, the land uses crossed by the reroutes are similar to the land uses crossed by the original Line 3 replacement pipeline route. It is, therefore, likely that rare plants will be observed along these reroutes during the 2015 supplemental vegetation surveys. No rare plants or rare ecological communities observed during the 2013 and early June 2014 vegetation surveys are located in the vicinity of the RSV sites and are, therefore, not anticipated to affect construction of RSVs or any associated towers. However, if rare plants or rare ecological communities are observed in the vicinity of RSV sites and tower locations during construction and/or supplemental vegetation surveys, mitigation for those rare plants and rare ecological communities will be recommended at that time.

The supplemental vegetation surveys in Alberta, Saskatchewan and Manitoba encountered a number of different vegetation communities which included tame pasture, native grassland, deciduous forest and wetland areas. No COSEWIC or SARA-listed species and no species designated under the Alberta Wildlife Act were observed during the supplemental vegetation surveys in Alberta. There were eight ACIMS-listed rare species observed along the Line 3 replacement pipeline route within Alberta. There was one rare ecological community observed along the Line 3 replacement pipeline route in Alberta. Two federally-listed species, small-flowered sand-verbena and smooth arid goosefoot, were observed in Saskatchewan during the supplemental surveys in August 2014. Small-flowered sand-verbena is listed as Endangered under COSEWIC, SARA and the Saskatchewan Wildlife Act. Smooth arid goosefoot is listed as Threatened under COSEWIC and SARA. There were 17 SK CDC-listed rare vascular plant species and 1 SK CDC-listed rare non-vascular plant species observed during the supplemental vegetation surveys along the Line 3 replacement pipeline route in Saskatchewan. No COSEWIC or SARA-listed species and no species designated by the Manitoba Endangered Species and Ecosystems Act were observed during the supplemental vegetation surveys in Manitoba. There were two MB CDC-listed rare vascular plant species and one MB CDC-listed rare non-vascular plant species observed during the supplemental vegetation surveys along the Line 3 replacement pipeline route.

No Prohibited Noxious weeds were observed along the Footprint in Alberta. However, 8 Noxious weeds and 41 additional non-listed, non-native species were observed in Alberta. There were 15 Noxious weeds, 8 Nuisance weeds and 59 additional non-listed, non-native species observed along the Footprint in Saskatchewan. There were 23 Noxious weeds and 29 additional non-listed, non-native species found to occur along the Footprint in Manitoba.

The objectives of this report were to provide: updates on Project details that have occurred after the ESA was filed; consultation updates that have occurred from July 1 to December 24, 2014; the environmental setting for reroutes that have occurred after the ESA was filed; and the results of the supplemental vegetation surveys that were conducted in late June 2014 and August 2014. The successful implementation of the recommendations in this report and the mitigation measures outlined in the EPPs (Appendix 1 of the ESA) [Filing IDs A4E6X1 to A4E6X4] are expected to satisfy any guidelines associated with the applicable Alberta, Saskatchewan and Manitoba provincial legislation.
