Traffic Impact Assessment Proposed Glendell Mine Expansion Modification to Development Consent

1. Introduction

In January 2007, Parsons Brinckerhoff (PB) was engaged by Xstrata Mount Owen Pty Ltd (XMO) to prepare a Traffic Impact Assessment for the proposed modification to the Glendell Mine development consent.

The proposed modifications to the Glendell Mine development consent will enable the integration of Glendell mine with Mt Owen Complex operations whilst enabling the implementation of a revised mine plan.

Glendell Mine is located off Hebden Road, approximately 25km north-west of Singleton, NSW.

It is proposed to develop Glendell Mine and associated infrastructure, south of the existing MOC. The proposed development involves a mechanical maintenance facility, fuel farm and associated small office complex, creek diversion and a staging dam.

XMO proposes to commence works at Glendell Mine with a construction crew of up to 100 staff in early 2008. Construction is expected to be complete by late 2008. Mining operations are expected to ramp up from 50 mining operations staff in late 2008 to 150 mining operations staff from early 2009. The proposed modifications include mining operations over a minimum 16 year period.

The existing consent for the Glendell Mine includes an approved mine access road located on the sharp bend, immediately adjacent to the Bowmans Creek Bridge, to be utilised by up to 600 employees.

The proposed location of the new Glendell Mine access road (approximately 1.2 kilometres from its intersection with the New England Highway) will provide much improved sight distances and be utilised by significantly less employees than previously approved. In combination these factors should result in improved traffic safety at this intersection.

PB’s scope of work for the project was to assess the impact that increased traffic associated with the construction and operation of the Glendell Mine might have on the existing road network, intersections and road safety issues.

The specific tasks included in PB’s brief arose from the development of the scope of work to modify the existing consent for Glendell mine (see section 2 below), and consisted of:

ƒ assessment of the change in intersection performance characteristics of the New England Highway/Hebden Road and Hebden Road with the proposed new mine access road

ƒ identify any safety issues associated with the proposed modifications

ƒ identify whether there are any infrastructure constraints for construction traffic

A visual inspection of bridges and other significant structures along Hebden and Antiene roads was undertaken to identify infrastructure that might limit construction traffic.

By the way of background information, it its worthwhile noting that in 2006 PB undertook a structural/engineering assessment of the Bowman’s Creek Bridge. The assessment confirmed that the bridge was in a satisfactory structural condition and had sufficient capacity to support B-Double trucks.

This traffic assessment provides a summary of the existing road and traffic conditions, a description of the proposed modifications that relate to traffic and a description of the impacts of the proposed modifications on:

ƒ the intersection of Hebden Road and New England Highway

ƒ the intersection of the mine access road and Hebden Road

ƒ Hebden Road railway crossing

ƒ Bowmans Creek single lane bridge

2. Existing Situation

2.1 Location

The proposed Glendell Mine is located approximately 18km north-west of Singleton, NSW.

The facility will generally be accessed via New England Highway, Hebden Road and a mine access road. A locality plan, illustrating the proposed facility and access route to this facility is provided in Appendix A.

The New England Highway is a national highway which links Newcastle and . This is the major arterial road between Muswellbrook and Singleton and is of single lane construction where it passes its associated intersection with Hebden Road.

The Hebden Road / New England Highway intersection is located approximately 18km from Singleton, NSW. Hebden Road is a rural road, maintained by , with no specific provision for separating pedestrians or cyclists. The road services a number of scattered farm dwellings and a number of mine owned houses before the entrance to the Mt Owen Complex (MOC), comprising the Mt Owen and Ravensworth East Mines and the associated Mt Owen Coal Handling and Preparation Plant (CHPP), some 7 kilometres from the New England Highway Intersection. Beyond the MOC entrance is the intersection of Hebden Road and the access road to Hebden Quarry.

The first 8 kilometres of Hebden Road (from New England Highway) are a 7m wide sealed road formation with no shoulders and limited areas of centreline marking. Further north of MOC access road, Hebden Road is a single lane road of poorer quality seal. The southern portion of this road (i.e. from the New England Highway to the MOC access road) is the main access for MOC employees.

Antiene Road connects the northern end of Hebden Road to the New England Highway, approximately 12 kilometres east of Muswellbrook, via the northern shores of . While 10% of MOC employees that travel to work each day from Muswellbrook and locations further north will utilise Antiene Road, 90% of employees will utilise the intersection of Hebden Road and New England Highway.

Figure 2-1 below illustrates the arrangement of the New England Highway and Hebden Road intersection and associated rail crossing and single lane bridge.

Figure 2-1: General NEH/Hebden Road Intersection and Associated Features

2.2 Speed Limits

The speed limits for these roads are:

• New England Highway (NEH) 90 km/h

• Hebden Road within 500m of NEH 60 km/h

• Hebden Road remainder 80 km/h

• Antiene Road 80 km/h

2.3 Street Lighting

No roads or intersections are street lit.

2.4 Road Condition and Infrastructure Assessment

A road and infrastructure condition assessment was undertaken in June 2005, the results are presented below, with the details provided in Appendix B.

The key findings were that, in general terms, the condition of bridges and culverts along Hebden Road and Antiene Road was satisfactory.

As noted in Section 1, a structural condition and capacity assessment of Bowmans Creek Bridge was undertaken by PB in 2006.

Traffic Impact Assessment Proposed Glendell Mine Expansion Modification to Development Consent

2.5 Intersections

2.5.1 New England Highway Hebden Road Intersection

The intersection between New England Highway and Hebden Road at Ravensworth is identified as a “Type C” (as per Austroads Guidelines) or “CHR” (as per RTA Road Design Guidelines) standard intersection with deceleration lanes provided for traffic turning from both directions of travel on the New England Highway.

The northbound right turn lane is 110 metres long and the south bound left turn lane is 80 metres long. The southbound acceleration lane on to the New England Highway from Hebden Road is 71 metres long. There is no protected turn for right turning traffic out of Hebden Road.

Photographs of the intersection are provided as Figure 2-2 and Figure 2-3.

Figure 2-2: Southbound exit to New England Highway from Hebden Road

Figure 2-3: Southbound Approach to Hebden Road intersection

PARSONS BRINCKERHOFF 2118689A-RP_7131 Page 5

Traffic Impact Assessment Proposed Glendell Mine Expansion Modification to Development Consent

These deceleration lengths meet the requirements of RTA Road Design Guide (RDG) being 125 and 85 metres for the right and left turns respectively into Hebden Road, being greater than the minimum 90 and 80 metres respectively.

The RTA RDG acceleration lane minimum length (for the speeds of the intersecting roads) is 315 metres. The existing southbound acceleration lane is shorter than this RTA RDG requirement. The existing acceleration lane should be extended to at least 315m in length to comply with the RTA RDG.

It should be noted, shorter acceleration lanes are not an unusual situation along the New England Highway, and many intersections between Muswellbrook and Singleton are of similar configuration.

The swept paths for turning heavy vehicles into and out of Hebden Road are accommodated within the intersection. This means that the wheel paths of heavy and long vehicles are contained within the pavement area of the intersection and do not intrude onto the shoulders or across traffic islands or double white lines.

2.5.2 Sight Distance

The theoretical Safe Intersection Entering Sight Distance is available (drivers eye height of 1.15 metres to the opposing drivers eye height of 1.15 metres) at the New England Highway and Hebden Road intersection.

2.5.3 Intersection Geometry

The existing New England Highway and Hebden Road intersection has been observed to operate with left turning truck and dog trailer combinations utilising the sealed full width shoulder as an acceleration lane for southbound movements. The incidence of this behaviour is expected to increase with the additional traffic flows generated from the development especially during the construction period when there will be an increase in the volume of heavy vehicles.

As the majority of heavy vehicles utilising the New England Highway/Hebden Road intersection is expected to remain as truck and dog trailers, there are no physical changes proposed for the intersection geometry.

2.5.4 Level Crossing

At approximately 200 metres along Hebden Road from the intersection with New England Highway is a level railway crossing controlled by flashing lights, bells and boom gates over the Main Northern Railway. A photograph of this level crossing is provided as Figure 2-4.

PARSONS BRINCKERHOFF 2118689A-RP_7131 Page 6

Traffic Impact Assessment Proposed Glendell Mine Expansion Modification to Development Consent

Figure 2-4: Westbound Approach to Level Crossing along Hebden Road

Umwelt confirmed, via email, on 24 April 2007 that (based on information provided by ARTC) 100 freight, coal and passenger trains would utilise the level crossing daily, with an estimated peak of up to 6 trains per hour.

2.5.5 Single Lane Bridge

At approximately 600 metres from the intersection with New England Highway, Hebden Road crosses a 4.7m wide single lane bridge over Bowmans Creek. The bridge is controlled by a “Give Way” sign facing eastbound traffic which reduces the likelihood of any queuing across the railway line. A photograph of the Bowmans Creek Bridge is provided as Figure 2-5.

Figure 2-5: Western Approach to Bowmans Creek Bridge

2.6 Traffic Volumes

2.6.1 Average annual daily traffic

The Average Annual Daily Traffic (AADT) data from RTA Foy Brook Bridge count station 05.037, in the vicinity of Ravensworth, was used to trend traffic growth on New England Highway. The location of the count station is illustrated in Figure 2-6.

PARSONS BRINCKERHOFF 2118689A-RP_7131 Page 7

Traffic Impact Assessment Proposed Glendell Mine Expansion Modification to Development Consent

Figure 2-6: RTA Foy Brook Bridge count station location

Table 2-1 illustrates the historic traffic growth on the New England Highway at Foy Brook Bridge, located approximately 2.5km south of Ravensworth and the intersection of Hebden Road and New England Highway.

This rate of growth has reduced between 1995 and 2001 to a compound rate of negative 2.9% per annum. The AADT showed an increase between 2001 and 2004, where a compound rate of 2.6% per annum was recorded. A positive growth trend is expected in the short term.

On average, a growth of 2.4% has been recorded over a 14-year period. This was used to estimate the AADT for 2007 to be 12,900 vehicles. The growth rate of 2.4% was also used to estimate future background traffic volumes for both the New England Highway and Hebden Road to ensure an adequate margin for growth.

The existing traffic on Hebden Road is estimated to be in the vicinity of 600 -700 AADT (Average Annual Daily Traffic). Aside from traffic associated with the MOC (425 vehicles per day), this also includes allowance for Hebden Quarry (30 vehicles per day) and local users (80 vehicles per day) plus visitors, deliveries and other miscellaneous traffic.

2.7 Intersection counts

Traffic counts were undertaken as part of this project study of the intersection of Hebden Road and New England Highway. The traffic counts provided a general indication of current traffic flows. The surveys were conducted on Friday 15 September 2006, with a repeat survey on Monday 25 September 2006, for the morning and evening peak periods between 5:00AM and 9:00AM and between 5:00PM and 9:00PM, respectively. The survey periods included two hours before and two hours after the shift change times at the existing XMO site that occurred at 7AM and 7PM.

The survey results recorded the morning peak hour between 6.15AM and 7.15AM, with the evening peak hour between 5:00PM and 6:00PM. Figure 2-8 and Figure 2-9 illustrate the intersection turning movement volumes in passenger car units (PCU) per hour, for the two peak periods surveyed. These volumes were then used in the level of service assessment using SIDRA modelling. The traffic characteristics can be summarised as follows:

ƒ New England Highway north of Hebden Road, carries 1,407 PCU in the morning peak hour and 1,038 PCU, two-way, in the evening peak hour

ƒ New England Highway, south of Hebden Road, carries 1,525 PCU in the morning peak hour and 1,071 PCU, two-way, in the evening peak hour

ƒ Hebden Road, east of New England Highway, carries 146 PCU in the morning peak hour and 43 PCU, two-way, in the evening peak hour on the New England Highway. (Note: it should be noted that the peak mine traffic period is different to the highway peak period)

Note: For the SIDRA analysis, cars and trucks are represented as PCU. PCU = Cars + 3 x Trucks

2.8 Current mine traffic

The MOC currently employs 479 employees, split between 346 staff and 133 contractors. It operates in two 12-hour shifts, from 7am to 7pm, and from 7pm to 7am, with approximately 80-100 mine shift workers and 45 supervisory and administrative staff on day work. There is typically a 30 to 40 minute overlap between people arriving and departing their shifts.

Car pooling is common amongst mine employees, with figures showing around one third of employees travelling as passengers with a colleague (Umwelt, 2003). This translates as 1.5 employees per vehicle, or 1.33 vehicle movements per employee, per day.

Assuming that two thirds of all employees and contractors work on any single day, then 320 people would travel, or 425 two-way vehicle trips would be generated per day.

Employee statistics provided by XMO gave the residential locations of the staff employed at the MOC. The distribution is summarised in Table 2-2.

PARSONS BRINCKERHOFF 2118689A-RP_7131 Page 10

Traffic Impact Assessment Proposed Glendell Mine Expansion Modification to Development Consent

Table 2-2: Employee residential locations

Place of Residence No. of Employees Percentage Singleton Shire 183 53% 30 9% Scone Shire 14 4% Maitland 63 18% Cessnock 22 6% Newcastle 17 5% Other 17 5% TOTAL 346 100%

It has been assumed that the same residential distribution applies to the 133 contractors who with the 346 employees make up the 479 employees at MOC.

Employees living in the Scone and Muswellbrook Shires, located to the north of the MOC, accounted for just 13% of the work force. The primary route into the complex is via Ravensworth. However, northbound motorists have the option of travelling north along Hebden Road, then via Antiene Road and rejoining the New England Highway (approximately 7 km south of the southern outskirts of Muswellbrook). Presently, this route is used by an estimated 10% of employee traffic, i.e. 90% of employee traffic uses the intersection of Hebden Road and New England Highway (Umwelt, 2003).

Directional statistics from the traffic survey show that for vehicles arriving via the Hebden Road intersection, 88% turn right into Hebden Road from the south, and 12% turn left into Hebden Road from the north. Similarly, for vehicles departing Hebden Road, 92% turn left and 8% turn right onto the New England Highway.

2.9 Road Safety Issues

The five year RTA NSW crash records (2001 – 2005 inclusive) for the New England Highway and Hebden Road have been analysed to determine the accident risk associated with travel to and from the Glendell Mine site.

2.9.1 New England Highway

The five year RTA NSW crash records (2001 – 2005 inclusive) for the length of New England Highway between John Street, Singleton and the Old New England Highway (approximately 4 km to the north of Hebden Road intersection) are summarised in Figure 2-10. The figure illustrates a gradual decline in the number of crashes during this period.

No of Crashes 11 8 3 5 4

Of the crashes within “Singleton township” section, 18 events occurred adjacent to, or within the Bridgman Road intersection.

There are a number of “clusters” of crash sites along the New England Highway between the “Singleton township” section and its intersection with Hebden Road. The worst areas are located at about:

ƒ ~500m to the north of Rix’s Creek Road with 6 crashes (~10.5km south of intersection of Hebden Road and New England Highway)

ƒ ~1000m to the north of Dight’s Crossing Road with 5 crashes(~6.5km south of intersection of Hebden Road and New England Highway)

ƒ ~200m to the north of Lemington Road with 9 crashes (~5km north of intersection of Hebden Road and New England Highway)

This crash rate indicates a frequency of approximately 0.95 reportable crashes per million vehicle kilometres of travel.

Crash data used in this analysis is enclosed at Appendix C.

PARSONS BRINCKERHOFF 2118689A-RP_7131 Page 12

Traffic Impact Assessment Proposed Glendell Mine Expansion Modification to Development Consent

2.9.2 Hebden Road

The five year RTA NSW crash records (2001 – 2005 inclusive) show only a single crash on Hebden Road in the 5 year period. No crashes were recorded at the intersection of New England Highway and Hebden Road.

2.10 Road Safety Audit

A separate Road Safety Audit has been conducted for the portion of Hebden Road between the proposed mine access road and the New England Highway. The results of the audit, other associated safety issues and risk assessment are presented in Table 2-4. The risk assessment is that adopted by Austroads. Definitions are contained in Appendix D and photographic examples of these issues are illustrated in Appendix E.

* Note: narrow bridge warning signs and chevron alignment markers have been installed since the audit

** Note: the accident damage to the southbound approach has since been repaired but the existing bridge damage remains

g Note: XMO and Singleton Council have agreed to address these issues through remedial works. See 2.10.1 below

This audit illustrates that there are two high issues remaining, following works conducted since the audit, and five issues considered medium risk. Under Austroads criteria the high risk items (which both relate to the vehicle barriers) should either be corrected or the risk reduced.

The medium risk items should be corrected if the cost is medium but not prohibitive. This is a matter for the asset owner to address.

The requirement to correct these issues is an Austroads criterion, which exists regardless of the increase in traffic flow associated with the Glendell Mine.

A separate detailed safety and structural options assessment is required to determine and select appropriate remedial measures.

2.10.1 Planned Remedial Works for Bowmans Creek Bridge and approaches

As part of the approvals process for the construction of the XMO CHPP Upgrade, in the period since the Road Safety Audit was conducted, XMO have made a commitment to Singleton Council to fund the following improvements to the approaches for the bridge over Bowmans Creek:

ƒ provision of new guardrail and terminals

ƒ widening of road formation at both ends of bridge to improve geometry and passing space.

ƒ re-shaping of pavement at northern end of bridge to remedy problem with excessive cross fall

ƒ re-sealing or asphalting surfacing of both approaches to eliminate ravelling (i.e. eliminating the existing issue with surface roughness).

PARSONS BRINCKERHOFF 2118689A-RP_7131 Page 14

Traffic Impact Assessment Proposed Glendell Mine Expansion Modification to Development Consent

Plans showing the scope and intent of these improvements have been agreed with Singleton Council and are available for viewing upon request.

XMO have also agreed to fund an investigation of options (including limited structural assessment) for replacement of guardrail across the bridge in consultation with Singleton Council to maintain its ongoing serviceability.

.

It should be noted that these planned improvements address many of the issues raised in the Road Safety Audit.

2.11 Intersection Performance Characteristics

The operation of the New England Highway/Hebden Road intersection with, and without, the proposed Glendell Mine development was assessed using the aaSIDRA (SIDRA) intersection modelling software package. SIDRA calculates intersection performance measures such as:

ƒ level of service (LoS)

ƒ degree of saturation (DoS)

ƒ average intersection delay

ƒ queue length

ƒ existing performance

A description of these measures is contained in Appendix D.

The results of the operational performance analysis of the existing circumstances for the intersection of New England Highway/Hebden Road are provided in Table 2-5.

Table 2-5: Existing intersection performance

Peak hour DoS Ave delay Current LoS Max queue Seconds metres AM peak 0.57 14 A 1 PM peak 0.33 15 B 1 Source: SIDRA model Note: DoS = Degree of Saturation, Average Delay in seconds, LoS = Level of Service and Maximum Queue Length in vehicles

The intersection of New England Highway and Hebden Road operates as priority controlled intersection. There is a left turn slip lane and right turn lane provided on the New England Highway to minimise delays from the turning traffic.

The intersection is currently operating with ample spare capacity, minimal delays and virtually no queues. This correlates closely with observations on site during the peak periods.

2.12 Level Crossing Performance

An assessment of the performance of the rail level crossing has been undertaken to ascertain the likely existing delays to traffic waiting to cross the rail line.

Umwelt confirmed, via email, on 24 April 2007 (based on information provided by ARTC) that an estimated 100 freight, coal and passenger trains would utilise the level crossing daily, with an estimated peak of up to 6 trains per hour. Based on existing train lengths and operational speeds of approximately 40km/hr, an average crossing closure of 110 seconds per train has been calculated. This analysis is based on the worst case of a coal train crossing, with passenger trains affecting the rail crossing for a significantly shorter period.

The results of the analysis illustrate that the average delay for traffic is approximately 1 minute and that the queue length could reach 100 metres for 5 percent of the time. This queue is well clear of the New England Highway intersection and is considered acceptable.

This duration of delay is considered to be significant and in urban situations is a Level of Service E. This is typical of many urban level crossings in Australia.

2.13 Single Lane Bridge Performance

An assessment has been undertaken for the delays associated with the single lane bridge across Bowmans Creek. The results of the AM peak analysis illustrates that the average delay for southbound traffic (northbound has priority on the bridge) is 18.5 seconds and the queues could reach 28 metres for 5 percent of the time. This level of delay is considered quite acceptable at Level of Service B.

Traffic Impact Assessment Proposed Glendell Mine Expansion Modification to Development Consent

3. Description of Proposed Modifications

The proposed modifications to the Glendell Mine development consent will enable the integration of Glendell mine with Mt Owen Complex operations whilst enabling the implementation of a revised mine plan.

It is proposed to develop Glendell Mine and associated infrastructure, south of the existing MOC. The proposed development involves a mechanical maintenance facility, fuel farm and associated small office complex, creek diversion and a staging dam.

XMO proposes to commence works at Glendell Mine with a construction crew of up to 100 staff in early 2008. Construction is expected to be complete by late 2008. Mining operations are expected to ramp up from 50 mining operations staff in late 2008 to 150 mining operations staff from early 2009. The proposed modifications include mining operations over a minimum 16 year period.

The existing consent for the Glendell mine includes an approved mine access road located on the sharp bend, immediately adjacent to the Bowmans Creek Bridge, to be utilised by up to 600 employees.

The proposed location of the new Glendell Mine access road (approximately 1.2 kilometres from its intersection with the New England Highway) will provide much improved sight distances and be utilised by significantly less employees than previously approved. In combination these factors should result in improved traffic safety at this intersection.

3.1 Surrounding Development

Hebden Road is the main access to the MOC, comprising the Mt Owen and Ravensworth East Mines and the associated Mt Owen Coal Handling and Preparation Plant (CHPP).

The MOC will continue to be serviced via the existing access road off Hebden Road.

XMO are currently undertaking an upgrade of the Mt Owen CHPP as part of works for approved as part of the Mt Owen development consent issued in 2004. The XMO CHPP upgrade commenced in early 2007 and is expected to be completed by late 2007.

A summary of relevant information previously gathered is summarised below:

ƒ MOC currently employs 346 permanent staff and 133 others (casual staff or contractors)

ƒ MOC currently operate in two shifts of twelve hours each; 7am to 7pm and 7pm to 7am; however these operations may change to two shifts of 10.5 hours each with morning shift commencing at 0700 and afternoon shift finishing at 1630

ƒ there is typically a 30 to 40 minute overlap between people arriving and departing each shift

ƒ car pooling is common and approximated to be 3 workers per car

ƒ 90 construction staff are expected at XMO during peak construction period of the XMO CHPP expansion project in 2007

PARSONS BRINCKERHOFF 2118689A-RP_7131 Page 17

Traffic Impact Assessment Proposed Glendell Mine Expansion Modification to Development Consent

ƒ mining operations staff at XMO will be increased by 3 additional staff from 2008, following the completion of the XMO CHPP upgrade. This will increase MOC total mining operations staff from 479 to 482.

3.2 Peak Traffic Conditions

It is reasonable to consider that the Mt Owen Mine morning shift traffic plus the traffic associated with commencement of construction and mining operations activities within Glendell Mine are representative of maximum traffic loading along Hebden Road. This is expected to occur between the hours of 6.00am and 7.00am Monday to Saturday.

Continued 12 hour shifts for MOC mining operations should ensure traffic peaks at the end of shift should be smaller than those at the start of morning shift, assuming construction workers leave site prior to the end of the mine operations day shift. End of shift traffic peaks may increase to traffic levels similar to that of start of morning shift if 10.5 hour mining operations shifts are implemented at the MOC.

Traffic impacts from commencement of construction and mining activities within Glendell Mine (100 construction and 50 operation staff) are expected to occur throughout 2008.

As outlined in Table 4.1 the operational traffic generated from the proposed modifications of Glendell Mine, in the subsequent years, is expected to be at a similar level to the 2008 levels. i.e. mining operations increases by 100 staff and construction workforce reduces from 100 staff to zero.

4. Impacts of the Proposed Modifications

4.1 Traffic Generation

As outlined in Section 3.2 future peak traffic conditions are expected during the activities associated with the construction and initial mining operations at Glendell Mine.

Traffic associated with ongoing mining at the MOC are included (including 3 additional mining operations staff), as background traffic, in these peak traffic conditions.

4.1.1 Construction vehicles

The majority of construction workers are expected to commence on site at 7.00AM and it is assumed that the busiest time for construction traffic is between 6.00AM and 7.00AM Monday to Saturday. The civil construction workers are likely to finish from 3.00PM onwards with a peak at about 5.00 – 5.30 PM.

The construction program for the Glendell Mine civil works estimates that traffic movements will occur throughout 2008. During this time, up to 10 separate construction activities will take place simultaneously at the site. XMO advise that they expect 100 construction workers on site during the peak of construction work.

Carpooling will also occur, and has been assumed to be at the same rate as mine traffic (1.5 persons per vehicle). Approximately 133 additional trips may be generated from the construction and initial mining operations phase of Glendell, during the peak periods. The above figures do not include construction delivery vehicles, such as concrete trucks and material deliveries, which are predicted to number 20 vehicles per day. The heavy vehicles should be spread evenly over a ten-hour period, therefore, on average; two trucks will arrive and leave every hour. All trucks were assumed to use the New England Highway/ Hebden Road intersection.

4.1.2 Mining vehicles

XMO has provided expected manning level forecasts for their operations at the MOC. Heavy vehicle numbers are not expected to increase as all coal transportation will be hauled on the internal road network.

4.1.3 Construction and Mine Operations Staff

Table 4.1 illustrates the total numbers of staff during construction and initial mining operations period at Glendell Mine.

Table 4-1: Mine and construction staff

2006 2007 2008 2009 Mining Operations 479 479 532 632 Construction 0 90 (CHPP) 100 0 Total staff 479 569 632 632 % Increase from existing 19% 32% 32%

As illustrated in Table 4-1, total staff numbers are expected to be the same during construction and subsequent mining operations, at 32% above current levels.

The comparison between the existing and proposed construction and mining operations workforce during peak traffic conditions is illustrated in Figure 4-1.

4.2 Trip Distribution and Assignment

For the purpose of assigning future trips generated by Glendell Mine on the road network, the traffic distribution illustrated in Table 4-2 was applied. This distribution was derived from the traffic counts at the intersection of New England Highway and Hebden Road.

To present a conservative analysis, Hebden Road was assigned 100 percent of the trips generated by Glendell Mine. No traffic was assigned to the western access road, Antiene Road, when studying this access with the New England Highway.

Table 4-2: Assumed traffic distribution based on traffic counts at the New England Highway/ Hebden Road intersection

Access Routes AM Peak PM Peak In Out In Out New England Highway to/from Singleton 89% 93% 90% 88% New England Highway to/from Muswellbrook 11% 7% 10% 12%

Based on the traffic distribution illustrated in Table 4-2, the inbound and outbound morning and afternoon peak traffic volumes using the New England Highway/Hebden Road intersection were forecast and illustrated in Table 4-3.

Figure 4-3 and Figure 4-5 present the estimated ‘peak hour’ traffic volumes in the design year based on the projected background traffic.

Figure 4-4 and Figure 4-6 illustrate these estimated ‘peak hour’ traffic volumes plus the trips from construction and initial mining operations, an additional 107 trips generated during both the morning and afternoon peak hours (assuming the same shift end).

Although the afternoon construction and employee traffic peaks are expected to occur at different time periods, under a conservative ‘worst case’ approach (which reflects the proposed potential 10.5 hour shift period), the assessment has been undertaken to combine all the peak traffic flows from mine, office and construction traffic into an hour to assess a theoretical peak demand scenario during the peak traffic period.

4.2.1 Intersection Performance

New England Highway/Hebden Road

The forecast traffic flow from the Glendell Mine development is 153 construction vehicles and 66 mining operations vehicles per day. This forecast level of traffic flow (during construction and initial mining operations) was added to the forecast background 2008 traffic flow, to measure the likely peak hour performance of the New England Highway/Hebden Road intersection.

The predicted operational performance at the New England Highway/Hebden Road intersection, including traffic associated with Glendell Mine construction and initial mining operations, is presented in Table 4-4.

Table 4-4: Intersection performance with development in 2007

Peak hour DoS Ave delay Forecast LoS Max (Seconds) queue(m) AM peak 0.592 2.0 Average for whole intersection A Worst movement 0.592 37.9 (RT) C 5 PM peak 0.341 1.3 Average for whole intersection A 5 Worst movement 0.341 19.5 B Source: SIDRA model Note: DoS = Degree of Saturation, Average Delay in seconds, LoS = Level of Service and Maximum Queue Length in vehicles RT=Right Turn

The results illustrate that the New England Highway/Hebden Road intersection would be expected to continue at existing levels of service, even with the addition of 2008 construction and initial mining operations traffic.

This period of Glendell Mine’s development is anticipated to be reflective of both 2008 construction/initial mining operations and subsequent years of mining operations.

4.2.2 Hebden Road/Proposed Glendell Mine Access Road

The proposed design of the intersection of Hebden Road and the proposed Glendell Mine access road is a “Type B” (as per Austroads Guidelines) or BAR (as per RTA Road Design Guidelines) based on the expected right turn movements of 64 turning vehicles being opposed by 51 through vehicles in the design hour.

An intersection performance analysis has been undertaken for the proposed intersection of the new access and Hebden Road. The results of this analysis are illustrated in Table 4-5.

PARSONS BRINCKERHOFF 2118689A-RP_7131 Page 24

Traffic Impact Assessment Proposed Glendell Mine Expansion Modification to Development Consent

Table 4-5: Hebden Road / New Access Performance Characteristics

Peak hour DoS Ave delay Current LoS Max queue AM peak 0.121 5.2 A 5 PM peak 0.075 7.1 A 1 This intersection is acceptable and will operate at Level of Service A.

4.2.3 Railway Level Crossing

It is estimated that 100 freight, coal and passenger trains would utilise the level crossing daily, with an estimated peak of up to 6 trains per hour (Umwelt, 2007). Based on train lengths of 900 metres and operational speeds of approximately 40km/hr an average crossing closure of 101 seconds per train has been calculated. This analysis is based on the worst case of a coal train crossing, with passenger trains affecting the rail crossing for a significantly shorter period.

An analysis of the expected delays and queue lengths at the crossing for the completed development illustrates that the average delay for traffic is expected to remain at approximately 1 minute, however queue length may exceed 112 metres for 5% of the time.

This duration of delay is considered to be significant and in urban situations is a Level of Service E. This is typical of many urban level crossings in Australia.

These queues will not extend to the New England Highway intersection. This illustrates that there is little change in the delays from the increased traffic associated with the proposed Glendell Mine modification.

4.2.4 Bowmans Creek Single Lane Bridge

The forecast traffic flows for concurrent shift times of mine and construction traffic for the single lane bridge have also been assessed.

The results of the analysis illustrate that the average delay for southbound traffic is expected to be approximately 34 seconds for the AM and PM peak hours. The queue length is expected to reach 61 metres for only 5% of the time. This is Level of Service C and is considered acceptable.

4.2.5 Cumulative Impacts

There are no cumulative effects expected from the delays at the Bowmans Creek single lane bridge and rail level crossing back to the NEH intersection, as the give way sign on the eastern side of Bowmans Creek single lane bridge allows traffic to flow and not queue back to the level crossing.

4.2.6 Road Safety

There will be an expected increase in traffic from the current estimate of ~ 600-700 vehicles per day to ~ 800-900 vehicles per day during construction and operation of the Glendell Mine infrastructure (an increase of 32% from existing levels).

This increase in traffic increases the risks at the single lane bridge by increasing the probable frequency of incidents. However since there has been only one crash on Hebden

PARSONS BRINCKERHOFF 2118689A-RP_7131 Page 25

Traffic Impact Assessment Proposed Glendell Mine Expansion Modification to Development Consent

Road in the past five years an increase of 32% still leaves the probable frequencies as occasional/improbable.

There will be a small increase in risk for travellers to and from Singleton. A simple extrapolation of the existing crash rate indicates that one additional crash could be expected on the New England Highway every 15 years as a result of this development.

4.2.7 Construction Traffic Impact

In general terms, the condition of structures along Hebden Road and Antiene Road was satisfactory, and it is not expected that additional construction traffic along these roads would adversely impact upon their performance or existing structural condition.

Discussions with XMO, Singleton and Muswellbrook Councils have expressed that the intension will be to prevent construction traffic from using Antiene Road. This will be implemented through signage on Antiene Road and construction contractor induction/education.

In the event that heavier or over-wide construction loads need to use Antiene Road, some caution should be used with regards to the following:

ƒ the existing timber bridge at Ch 8,600m (approximately 6.5km north of the Glendell Mine access road intersection) should not be used repetitively for construction deliveries without a full structural assessment, including analyses and load testing where appropriate.

ƒ Although unlikely to be used, any wide loads travelling to the site from the Muswellbrook direction via Antiene Road will need to ensure they can pass through the rail underpass at Ch 15,400 (approximately 14km north of the Glendell Mine access road intersection)

These points are unlikely to affect heavy vehicle traffic as construction deliveries will be directed to access the Glendell Mine site via the New England Highway/Hebden Road intersection.

The exact clearance from the roadway to overhead powerlines should be measured during hot weather and checked against any incoming high loads (with appropriate allowance for recommended clearances).

Traffic Impact Assessment Proposed Glendell Mine Expansion Modification to Development Consent

5. Conclusions

The proposed modifications of the Glendell Mine development consent will generate 32% more traffic than is currently forecast to exist on Hebden Road in 2008. This impact is significantly less than the previously approved Glendell Mine Development Consent, which had approval to generate approximately 100% more traffic on Hebden Road.

Whilst 32% more traffic may utilise Hebden Road during the construction and subsequent mining operations of the Glendell Mine, the existing “Level of Service” is not expected to alter significantly.

In traffic capacity terms the additional traffic generated by the proposed modifications can be readily accommodated. Estimates of traffic performance (delays, queues and congestion) under the peak traffic conditions indicate that Levels of Service will exceed those generally adopted for design purposes i.e. at or better than Level of Service C for:

ƒ New England Highway/Hebden Road Intersection

ƒ Bowmans Creek Bridge

ƒ Glendell Mine access road

Traffic performance at the railway level crossing shall remain at Level of Service E.

There are a number of existing safety issues along the route that are classified as high under the Austroads/RTA crash risk criteria. These issues exist irrespective of the additional traffic generated by the proposed modifications during peak traffic conditions and are being addressed by planned improvements jointly agreed between XMO and Singleton Council.

It is concluded that the proposed changes at Glendell Mine will have little impact on traffic, road environment and safety.

Traffic Impact Assessment Proposed Glendell Mine Expansion Modification to Development Consent

Definition of Intersection Performance

The selected design traffic forecasts were used in the computer programs aa SIDRA to assess the performance of each intersection. SIDRA is a computer package developed by AARB Transport Research Ltd in Australia for use as an aid for design and evaluation of a range of both signalised and unsignalised intersection types. It uses detailed analytical traffic models combined with interactive approximation methods to estimate capacity and performance statistics for an intersection. Some of the more appropriate performance measures provided for signalised intersections are described in the following section of this appendix.

The SIDRA analysis assumed the peak flow period to be one hour duration, 90% of the forecast traffic occurred during this one hour period.

Degree of Saturation

The degree of saturation is the ratio of traffic demand flow to capacity and is otherwise known as the volume capacity ratio. The degree of saturation for any traffic movement (for example, a right turn movement) is reported as the largest degree of saturation for any lane of the movement. Similarly, the degree of saturation for any approach to the intersection is reported as the largest degree of saturation for any movement on that approach and the degree of saturation for the intersection is reported as the largest degree of saturation on any approach.

Desirably, a movement degree of saturation is sought to be less than the nominated practical (target) degree of saturation which for this study was selected as 0.9. Higher degrees of saturation can be accepted with the recognition that the intersection will experience increasing congestion and delays. As a guide, Table 1 describes the likely conditions to be experienced at an intersection for various degrees of saturation.

Table 1 Intersection Degree of Saturation Degree of Saturation Intersection Conditions Less than 0.65 Below capacity, good operating conditions, low delays 0.65 – 0.85 Desirable range, satisfactory operating conditions 0.85 – 0.95 High range, increasing congestion and delays Over 0.95 Undesirable range, very high congestion and delays

Delay/Level of Service The delay to a vehicle is the difference between the interrupted and uninterrupted travel time through the intersection. SIDRA estimates the average delay for individual lanes, traffic movements, approaches or for the intersection as a whole. For this study the reported overall delay includes deceleration and acceleration delays for the major stop experienced by queued vehicles as well as the geometric delays experienced by all vehicles in negotiating the intersection. The delay is reported as the average delay per vehicle in seconds per vehicle.

The estimated Level of Service (LoS) for an intersection can be linked to a number of difference variables using SIDRA. For this study the LoS has been linked to the average delay per vehicle including geometric delays. Table 2 provides a description of the performance of an intersection for various LoS and delay.

Table 2 Intersection LoS and Delay LoS Average Delay (sec/veh) Intersection Conditions A Less than 14 Good operation B 15/28 Good operation with acceptable delays C 29-42 Satisfactory D 43-56 Operating near capacity E 57-70 At capacity, traffic incidents will cause significant delays F Over 70 Unstable operating conditions

Queue Length

SIDRA offers the ability to measure the length of vehicle queues which will occur at an intersection under defined operating conditions as the cycle-average queue or the back of queue for a range of percentile values. For this study the queue length has been measured as the 95th percentile value for the back of the queue. This value is that below which 95 per cent of all observed cycle queue lengths fall. Hence, it provides a measure in terms of the number of vehicles in the queue and the length of the queue (metres) based on the assumption that each light vehicle has an average length (nose to nose) of 6 metres and each heavy vehicle an average length of 12 metres.
