Traffic Management Sub-Plan Uncontrolled when Printed: Revision D Date: May 2010 The most significant impact to traffic at both substation locations is the importing of the transformers which requires the use of low loaders. This may cause traffic delays during the delivery and may require partial to total closure of the roadway adjacent to the substation during the installation of the transformer. At the Suffolk Park substation site Yagers Lane may require partial to total closure although minimal traffic volumes are expected to be affected due to the rural location of the roadway. The transmission line network will need to be connected to the substation upon completion of construction. The transmission line connection activities have the potential to cause partial or total closures of adjacent roadways while the lines are being linked to the new infrastructure. Similar to the line upgrades throughout the project, the connection will be completed in a short period of time (less than one day) so road closures will be temporary. 5.5.3 Upgrade of Skinners Shoot Road and Yagers Lane Skinners Shoot Road and Yagers Lane are to be upgraded to provide a suitable trafficable surface to accommodate the heavy vehicle movements and oversize loads associated with the transmission line upgrade and construction of the Suffolk Park substation. Country Energy intends to upgrade the sections of the road that are currently inadequate to allow construction traffic access. Country Energy will repair to the pre-existing state any damage caused by construction traffic. Skinners Shoot Road is in poor condition and is considered substandard for the current volume of daily traffic movements and the heavy vehicle movements required to transport electricity transformers. The first 1km of Skinners Shoot Road through the SEPP 14 Coastal Wetland system will require some minor upgrade works. This will include pavement improvements and widening of the sealed section from 3m to 4m with bitumen surfacing within the existing wider unsealed road formation. Some trimming of overhanging vegetation (branches only) will be required to minimise potential damage from vehicle strike. As it does not involve any clearing, levee construction, drainage or filling of the adjacent SEPP 14 Wetland, the Project does not trigger any of the referral and concurrence provisions of SEPP 14. Appropriate mitigation measures have been developed to ensure that the potential for any impacts upon the wetlands are eliminated during construction.

Traffic Management Sub-Plan Uncontrolled when Printed: Revision D Date: May 2010 Skinners Shoot intersects with Yagers Lane which is currently in poor condition and of insufficient width and strength to allow movements from a low loader. Roadwork will be required to ameliorate these issues, including road widening, pavement strengthening and installation of additional culvert capacity. This involves designing the roadway to accommodate the transformer transporter that is 3.5m wide and 22m long. Yagers lane services approximately twelve properties, which have been involved in consultation regarding the proposed upgrade works. During the construction period requiring partial road closures for greater than one day at a time, a sufficient width of roadway will remain open to traffic movements and allow access to properties in the event of an emergency. Access to the Suffolk Park substation site to be constructed will be through the presently disused piggery site to the west; with road access to the site is from Byron Bay via Yagers Lane, off Skinners Shoot Road. Byron Bay becomes very busy in the peak holiday season and during special events when roads can become congested, hence it is recommended to undertake the project activities outside of these conditions. The report by Tricend identified the potential issue of restricted turning conditions for larger vehicles at the intersection of Lawson and Shirley Street. Negotiating this turn may require the temporary closing of the affected roadways to allow the heavy vehicle unimpeded access through the intersection. Further liaison will be required with Council prior to any road improvements. 5.6 TRANSMISSION LINE CROSSING A ROADWAY Construction of transmission lines over roadways in locations where existing infrastructure is being upgraded is generally undertaken using the existing lines as a guide wire to allow the new transmission line to be pulled between the two poles without closing the roadway beneath the line. In locations where this is not an option, the two poles will be erected either side of the roadway and the roadway will then need to be closed for under approximately 15 minutes to allow for the line to be secured above the roadway.
