1 MOTI -- Five Strand Barbed Wire & Paige Wire Fence Specifications SCHEDULE 8 (and attached drawings) FIVE STRAND BARBED-WIRE FENCE SPECIFICATIONS Rocky Mountain District General If equipment is used at any time on this fence line project, the following applies; No rutting permitted. Machine blading of fence right-of-way to mineral soil can only be done if pre-authorized by a BCCA PDI Representative. Do not deposit trees or any non-biodegradable debris or petroleum products in any stream channel. All riparian and creek crossings must be avoided and a 10 meter machine free zone is mandatory unless otherwise authorized by a BCCA PDI Representative. Seed all disturbed soils on the fence right-of-way with a suitable grass mix approved by the BCCA PDI Representative. Water diversion bars may be required on steep sections of the right-of-way as assessed by a BCCA PDI Representative. In the event that archaeological material is encountered during this project, development activities involving land surface alteration must be suspended until qualified personnel can assess the situation. You also must contact the BCCA PDI Representative immediately if archaeological material is encountered. Existing fence to be dismantled, all non treated rails or logs can be left flat on ground, all other fence materials must be disposed of in an approved manner. Any existing fences damaged during activities related to this project shall be repaired by the contractor at his own expense to the satisfaction of the BCCA PDI Representative. The fence line integrity must be maintained. Any existing cross fences shall be connected to the new fence in accordance with fence specifications. Project works are to commence only when livestock are not adjacent to the fence line. These timelines must be coordinated between the contractor, livestock producer, and BCCA PDI Representative. Any permits required to work in the proximity of existing infrastructure (i.e. Telephone, Hydro, or Gas Lines) are the responsibility of the contractor. The Contractor shall ensure that its operations do not interfere with normal traffic in the area, and shall ensure that the vehicles, equipment and materials used in the performance of the work are located off the shoulder of the roadway, outside of the ditches, and in a location that will not be impacted by errant vehicles. Where any operations have the potential to affect traffic, the Contractor shall contact the local Ministry of Transportation and Infrastructure District office and comply with any requirements they may have with respect to use of the right-of-way and for traffic Appendix B Page 1 of 17

2 control. Contractor is responsible for submitting a Notice of Project to WorkSafeBC. This can be done online at; All slash must be on field side of the fence line. Contractor will have to provide the BCCA PDI Representative a Work Plan detailing start dates for project works. Contractor is responsible for applying the Fire Danger Class values for his/her operational area and adhering to Schedule 3, Restrictions on High Risk Activities of The Wildfire Regulation. Right-of Way Development All danger trees within the immediate area of operations shall be felled before operations commence. Removal of dead, defective, or leaning trees likely to fall across the fence and dispose of the slash as per specifications. Lop off all branches from the tops of all trees and buck the remainder of the tree into lengths, so each section of the tree makes contact with the ground. No debris including slash debris is to be left on the highways right of way. Removal of immature trees and re-growth within existing right-of-way of the fence to a total of 5 meters in width. Right-of-way development includes the felling, and lying flat to ground all small diameter trees, non merchantable under 6 inches outside the bark at stump height 30 cm. This will allow for proper maintenance activities. Minimum number of live trees to be removed; NO trees greater than 40 cm (16 ) in diameter at stump height may be cut, without prior permission from a MOTI Official or BCCAPDI Representative. Where bark beetles are a problem, felled trees should be bucked, lopped and scattered to eliminate beetle brood habitat. All merchantable Douglas Fir or Spruce felled, that is not decked, must be peeled by scoring all sides or cut into 20 cm lengths to prevent bark beetle infestations. The BCCA PDI Representative will be responsible for the final approval of slash disposal. All existing trials and roads must be kept free and clear of slash debris caused by right of- way- development. Fence must be placed on the field side of the utility poles if possible; to allow for access. Materials Wildlife Safe Fencing; high visibility fencing material (i.e. Vexar), or Top Rail, is required at all riparian areas and existing game crossings. Vexar material must have high visibility, be a minimum of twelve inches wide, with a minimum strength of 30Lbs per 100ft. All barbed wire gates require Tyten or equivalent gate openers. Wooden stays shall be installed as per Five Strand Barbed-Wire Fence Specifications (Schedule 7). Stays must be installed for fence completion to be approved. If steel posts are used, they must be planted no more than 16 apart. Wooden posts must be used for all bracing assemblies. Appendix B Page 2 of 17

3 Construction shall be carried out with all labour, tools, materials, equipment and incidentals supplied by the Contractor, as necessary, to complete all fencing work in accordance with good work practice. All materials are the responsibility of the contractor and must meet material specifications, including Class 3 barbed wire. All materials to be transported at contractor s expense to job site. FIVE STRAND BARBED-WIRE FENCE SPECIFICATIONS 1. To be constructed approximately metres long as indicated on the attached map. The fence line will be placed along the existing fence line right-of-way with minor re-alignment. Placement of the fence line beyond the existing right of way must approved by BCCA PDI Representative. 2. A five-metre (5 m) right-of-way is to be cleared on the fence lines. Slash must be disposed of as directed by the BCCA PDI Representative. ATV access is required on one side (wire side) of the fence line and horse and rider access on the adjoining side of the fence. 3. Special conditions as follows: ground disturbance must be kept to a minimum; and all large-diameter fir trees are to be left intact. 4.
