5 1. Introduction 1.1. Purpose of this Document Sinclair Knight Merz (SKM) has been commissioned by RATCH Australia Corporation Limited to provide engineering services to assist with providing engineering response to various Tablelands Regional Council (TRC) queries (TRC 51 TRC 54) regarding the traffic assessment report submitted earlier for the proposed Mt Emerald Wind Farm (MEWF) project at Walkamin. The purpose of this report is to provide engineering input to Council s queries regarding the impact that the proposed MEWF development will have on the surrounding road network, including vertical alignment checks for Hansen and Springmount Roads and various traffic generation figures during construction and operation Background and Current Situation The site of the project is situated on the Atherton Tableland within the jurisdiction of the Tablelands Regional Council (TRC) and is broadly located approximately 50 km south-west of the city of Cairns in far north Queensland. More locally, the site is approximately 18 km south of the township of Mareeba, 15 km north of Atherton and 6 km south-west of Walkamin. The major road adjacent to the proposed site is the Kennedy Highway running generally in a northsouth direction and forms part of the planned route for the transport of the wind tower components from their delivery location. This State-Controlled road is a two lane, two-way, sealed road with sealed shoulders, unsealed verges and is a gazetted m B-double route. From the main highway at Walkamin, the recommended (and most viable) route to the proposed MEWF site is via Hansen Road and Springmount Road, while direct access to the site is off Kippen Drive. All of these roads are locally controlled by the TRC and are generally two lane, two-way, sealed roads with unsealed shoulders and verges, except for Kippen Drive which is largely an unbound gravel road/track. Based on information received from RATCH, a maximum of 75 wind turbines are expected to be constructed on the site and a tourist viewing facility is likely to be built but its location is currently unknown. A plan showing the locality of the planned MEWF site and overall development layout is included in Appendix A for reference.

6 2. Engineering Response to TRC 51 TRC 51 Demonstrating the capability of the vertical profiles of Hansen and Springmount Roads accommodating any proposed drop deck or low loader transport of turbine components The assessment of the route to transport the turbine components along Hansen Road and Springmount Road to the site access at Kippen Drive has been carried out based on the following critical dimensions from Acciona Windpower s Transportation Manual and REPOWER Systems Manual for Transportation, access tracks and Crane Pads Assumptions It is assumed that RATCH Australia will undertake a separate route assessment for this project Horizontal layout check was not undertaken as part of this report as it is included in the previous report. Blades are transported on a truck and rear steerable dolly/trailer, thus making the horizontal geometry not being a constraint on this route. The blades and tower components are mounted high above the ground so it is deemed that the transport of blades will not have vertical conflicts. (This is based on the REPOWER Systems document which details vertical crest clearances to be no greater than 1.75m over 50m lengths). Rotor/hub/nacelle are transported on low loaders and vertical crest curves were assessed based on the following requirements Vertical profile requirements As per Acciona Windpower s Transportation Manual AW3000, short crest curves (less than 26m long) must not have the crest higher than 300mm or low loader transport vehicles will not be able to traverse the crest curve. The requirement for gradients has been checked against the requirements mentioned in section 2.4 RE Power Systems Wind Power - MM82/MM92/3.2M114/3.4M104 Specification for transportation, transport roads, access tracks and crane pads. The sections of the road which does not meet the criteria are shown in Table 1 and highlighted in the attached drawings included in Appendix C. The minimum vertical clearance height is 5 metres. Vertical clearance to overhead services and structures is not undertaken as part of this report. The report focuses on the vertical profile of the Hansen road. No detailed survey was available. Vertical geometry was developed as a best fit to the GPS data recorded during a vehicle drive through of the route.

7 Crests curve vertical geometry checked and shown in Table 1. Long sections and plans have been produced for two roads of approximately 10.9km in length. Refer to the drawings in Appendix C of this report. Table 1: Review of vertical profiles of Hansen and Springmount Road Mitigation for Location 9 Detail survey for the section of the road should be undertaken. After review of the survey and detailed reassessment of the conflict section, if the conflict remains, improvement to the vertical curve is recommended.

8 3. Engineering Response to TRC 52 TRC 52 Justification of traffic figures i.e. 40 single-unit truck trips per tower considering the possible external sourcing of road base material and concrete The traffic figure of 40 single-unit truck trips per tower has been based on ENERCON Specification E-82 Access Roads and Crane Platforms (77m Steel Tower) and possible external sourcing of road base and concrete. Clause 2.3 of the E-82 specification states that Use approx. 20 trucks to transport the crane accessories to the crane. On top of these, it was assumed that there would be another 20 truck trips per tower for road base and material during construction of the access road and Hansen Road pavement rehabilitation if required due to the heavy vehicle loading. This 40 single-unit truck trips per tower from the original specification provided by RATCH did not include various tower components including the foundation construction and the concrete towers. Based on the new information receive from RATCH regarding the transport of concrete and other wind tower components, the calculation of truck trips has been revisited. Therefore, the new calculation for all road base materials and all tower components including foundation construction, steel tower and blades are considered for the traffic generation for the wind farm. This earlier assumption was 40 single-unit truck trips during construction per tower through the road network for the 2 year construction period, making it 6,400 truck movements through the access during the construction phase. It was also assumed that a maximum of six semi-trailers (adapted to carry the propeller blades) per tower during construction. A maximum of 80 wind towers were planned to be constructed, equating to 960 truck movements through the access during the construction phase. However, it should be noted that RATCH advised that the number of towers be revised to 75 for the new calculation of vehicle movements. The new calculation details various vehicle types and calculates the trips generated by those various types of vehicles during different activities and phases of the construction period. For calculation purposes it is assumed that pavement rehabilitation of entire length of Hansen Road will be required due to the heavy loading. It is assumed that 150mm gravel overlay will be required for Hansen Road. A detailed pavement impact assessment should be carried out before construction activities. Table 2 shows a summary of vehicles movements during the 2 year construction and wind towers installation period. Details of these calculations are attached in Appendix B of this report. It should be noted that based on advice received from RATCH, the external sourcing of materials for the road base and the tower foundation will be done in the first 6 months, so there will be increased activities in the first six months during the construction period. This leads to the new figure of Annual average daily traffic (AADT) of 79 (arriving loaded and leaving the site empty) during different phase of the project. It was assumed for calculation purpose that there will be 300 days of working days per year, which may vary in reality depending on other circumstances and weather condition. SINCLAIR KNIGHT MERZ \\Au-cns-mdc02\projects\CBIF\Projects\CB24503\Deliverables\Reports\Technical Note- Mount Emerald Wind Farm Tarffic Impact Assessment_TRC 51-54_Rev 3.docx PAGE 4

9 It was also assumed that there was 12 working hours per day and peak hour traffic generation during construction and operation is 12% of the AADT which equates to approximately 10 vehicles per hour in the peak hour. Note that the inclusion of the new information regarding the transport of concrete and other wind tower components equates to only 2 additional vehicles per hour in the peak hour. Table 2: Vehicle Movements expected during 2 year construction and wind tower installation period SINCLAIR KNIGHT MERZ \\Au-cns-mdc02\projects\CBIF\Projects\CB24503\Deliverables\Reports\Technical Note- Mount Emerald Wind Farm Tarffic Impact Assessment_TRC 51-54_Rev 3.docx PAGE 5

10 4. Engineering Response to TRC 53 TRC53 Details on anticipated worker numbers and further justification of the 30 worker vehicles per day figure It was assumed in the previous report that a total of 30 vehicles per day (vpd) will be generated for workers during construction. It was also assumed that eight hour working days with daily traffic volumes during construction not generating typical peak hours but is instead spread equally over this working period. Following further details received from RATCH regarding Kippen Drive, internal access road construction within Wind Farm site and various construction activities relating to wind tower foundation construction, crane assembly, tower installation and energy commission; the anticipated worker numbers have been recalculated and is shown in Table 3 of this report. Total number of anticipated workers can be estimated as 150 people per day. It should be noted it is assumed that a 30-seater bus will bring in workers to site from nearby towns, and there will be some workers coming to site by individual vehicles. A maximum of 30 worker vehicles per day was assumed in the previous report taking this into account. Details of anticipated number of workers calculation is attached in Appendix B of this report. Table 3: Anticipated number of workers during the 2 year construction period Note: It should be noted that for calculating the anticipated number of worker vehicle trips, it has been assumed that there will be always new set of workers everyday, which will be not practical. It will probably be the same set of workers; however, they will produce equal number of trips if there was always a new set of workers every day.

11 5. Engineering Response to TRC 54 TRC 54 An estimate of the anticipated traffic increase of Hansen Road resulting from construction and operation of the development The calculation of traffic generation for construction and operation of the development is shown in Section 3 (TRC 52) of this report. Traffic has been recorded on a section of the Kennedy Highway that includes the intersection with Hansen Road by TMR in Similarly, another applicable traffic count has been conducted on Hansen Road near the intersection with Chewko Road by TRC in The results of these two traffic counts are shown below in Table 4 and display as an Annual Average Daily Traffic (AADT) value expressed as vehicles per day (vpd) and a corresponding percentage of heavy vehicles where applicable. A 10 year design life for Hansen Road was assumed making the design traffic year 2022 and a traffic growth of 3% per annum. Table 4: Existing AADT Kippen Drive is also planned to provide access to a viewing area after construction is complete and this will be utilised by some tourist traffic. Based on anecdotal evidence and local knowledge of the existing viewing area at the Windy Hill wind farm, an assumption has been made that 100 vpd will be utilising the proposed viewing area. The daily traffic movements estimated during construction and operation is shown in Table 5 and Table 6 detailing the anticipated traffic increase of Hansen Road for both construction and operation of the development. Note that the AADT for 2012 is calculated from Table 4 with a growth rate of 3% per annum, and the AADT increase for different phases of the construction period is taken from the calculated truck trips per day in Table 2. Table 5: Construction Period AADT increase SINCLAIR KNIGHT MERZ \\Au-cns-mdc02\projects\CBIF\Projects\CB24503\Deliverables\Reports\Technical Note- Mount Emerald Wind Farm Tarffic Impact Assessment_TRC 51-54_Rev 3.docx PAGE 7

12 It was also assumed that for residential purposes another 8 vehicle trips will be produced during the operation period, making it 108 vehicle trips during the operation period. Table 6: Operation Period AADT increase SINCLAIR KNIGHT MERZ \\Au-cns-mdc02\projects\CBIF\Projects\CB24503\Deliverables\Reports\Technical Note- Mount Emerald Wind Farm Tarffic Impact Assessment_TRC 51-54_Rev 3.docx PAGE 8

13 6. Conclusion This technical note has addressed the various queries from TRC (TRC 51- TRC54) and the following was determined. For TRC 51 query, it was found that only one location (Easter Approach to Granite Creek Causeway, Chainage 5775) in Hansen Road has some possible vertical crest issues for low loaders. This can be investigated further during the detailed design of the access road. For, TRC 52 to TRC 54 queries, detailed amended calculations has been included in this technical note. As shown in section 5, Table 5 and Table 6, there will not be significant traffic increase in Hansen road due to the construction and operation of the wind towers.
