1.0 Introduction Tetra Tech published a comprehensive Traffic Study Report in April of 2009 which was based on the Mine Plan of Operations (MPO). This traffic analysis examined the existing traffic conditions along State Route 83 (AZ-83) and also assessed potential future traffic conditions on AZ-83 associated with the Rosemont Copper Project (Project). The April 2009 traffic study included level of service (LOS) analysis of key intersections and roadway segments along AZ-83 for the Existing Year, Construction Year, Operations Year 5, and Operations Year 20. The study location and surrounding areas are displayed on Figure 1. Two (2) scenarios, Carpool (Scenario 1) and Partial Carpool (Scenario 2, 75% Carpool), were examined for Operations Year 5 and Year 20. A total of seven (7) key intersections and two (2) highway segments were analyzed. Segment 1 runs from the intersection of AZ-83 and the Interstate 10 (I-10) westbound (WB) on-and off-ramps to the intersection of AZ-83 and East Hidden Valley Road. Segment 2 runs from the intersection of AZ-83 and East Hidden Valley Road to the intersection of AZ-83 and Greaterville Road. Detailed descriptions on study locations and LOS analysis methods are available in the April 2009 traffic report.

This Technical Memorandum presents the results of three (3) additional scenarios analyzed as a supplement to the April 2009 Traffic Study Report and their impact on AZ-83. These additional scenarios include:

No Carpool (Scenario 3)

50% Carpool (Scenario 4)

50% Carpool with no Copper Concentrate Trucks (Scenario 5)

LOS analysis of intersections and roadway segments follow the methodologies presented in the April 2009 Traffic Study Report. Intersection analysis was conducted using SYNCHRO software,

2

which utilizes the Intersection Capacity Utilization (ICU) 2003 method. ICU 2003 provides a straight forward method of calculating an intersection's LOS. This method takes the sum of critical movement volume to saturation flow rates. The ICU LOS gives insight into how an intersection is functioning and how much extra capacity is available to handle traffic fluctuations and incidents. Highway segment analysis was conducted using Highway Capacity Software 2000 (HCS2000) which uses the methodology in accordance with the 2000 Highway Capacity Manual (HCM). Most public agencies strive to achieve and maintain a LOS of C or greater in their jurisdiction. Mitigations are discussed where the LOS analysis results show a LOS of D or worse.

Because the Construction Year trips are expected to be identical to the previous April 2009 Traffic Study Report values, LOS analysis results are also expected to be the same for the scenarios analyzed herein. Therefore, only Operations Year 5 and Operations Year 20 were considered for the additional scenarios. Existing Year conditions are also assumed to be the same as presented in the 2009 report.

The remainder of this Technical Memorandum is divided into the following sections:

Section 2.0: Traffic assumptions and future forecasts

Section 3.0: Operations Year 5 LOS Analysis

Section 4.0: Operations Year 20 LOS Analysis

Section 5.0: Analysis of results and potential mitigation measures

Section 6.0: Conclusions

2.0 Future Forecasts Traffic forecasts for this study were based on two (2) components:

Project Trips (trips generated by the Project); and

Background Trips (all other traffic not associated with the Project itself).

Project Trips were based on the estimated potential truck traffic and employee travel patterns. The Rosemont Project Mine Plan of Operations (WestLand, 2007) and Rosemont Copper Project Feasibility Study (M3, 2007, and 2009) were used to obtain information such as daily material delivery rates, truck schedules, and number of employees to apply in the traffic forecasts. In order to generate Background Trips, the average annual population growth rate of Pima County from 1990 to 2006 was used. A total of two (2) future years were considered in the analysis:

Operations Year 5; and

Operations Year 20.

The analysis year periods termed Operations Year 5 and Operations Year 20 represent the operational conditions of the Project at the beginning of years 5 and 20, respectively. Table 2.1

3

summarizes the traffic components for each year analyzed. The traffic volume due to the Project was divided into two (2) categories:

Commuter trips; and

Operations trips.

Commuter trips are trips generated by mine employees and Operations trips are trips generated by trucks. Most of the trips were assumed to originate from the Tucson area (75-80%). The remaining trips were assumed to be generated south of Greaterville Road.

Scenario 3 - No Carpool

Under this scenario, it was assumed that every employee would generate a single trip. The truck delivery patterns would follow those specified in the Rosemont Copper Project Feasibility Study (M3, 2007, and 2009). Scenario 3 also yields the highest Project related trips and is therefore considered the most congested scenario associated with the Project. Table 2.2 summarizes the assumptions used in analyzing Scenario 3.

Scenario 5 – 50% Carpool with no Copper Concentrate Trucks

Scenario 5 is similar to Scenario 4 in that 50% of the total employee workforce would carpool at an average rate of five (5) people per van, with the remaining 50% generating a single vehicle commuting trip per employee (i.e., no carpooling). In addition, it was assumed that truck deliveries would occur during peak periods. The difference between Scenario 4 and Scenario 5 is that copper concentrate would not be transported on AZ-83 under Scenario 5. Copper concentrate would be transported via pipeline to a loadout station on the west side of the Santa Rita Mountains. Table 2.4 lists the assumptions applied to Scenario 5.

All the above scenarios are classified as a Category II c development according to ADOT’s “Traffic Impact Analysis for Proposed Development” and Section 240 of ADOT’s “Traffic Engineering Policies, Guidelines, and Procedures”. Therefore, per the ADOT traffic impact study guidelines, mitigations are recommended within 1 mile of the proposed site. The assessment of potential Project traffic impacts on intersections and roadway segments under these scenarios are presented in Sections 3.0 and 4.0.

3.0 Operations Year 5 As described in Section 2.0, Operations Year 5 represents the Project’s operational condition at the beginning of Year 5. In order to fully analyze potential Project traffic impacts on AZ-83 and the selected intersections, LOS results were compared to LOS values with the Project not in operation. SYNCHRO and HCS2000 worksheets for Operations Year 5 are included in Attachments 1 and 2, respectively. Tables 3.1, 3.2, 3.4, and 3.5 present the study intersections’ corresponding ICU value and the LOS for Operations Year 5 during non-peak and peak seasons under Scenario 3 (No Carpool). Tables 3.3 and 3.6 describe the highway segment categories, corresponding LOS criteria values, and the LOS for Operations Year 5 under Scenario 3.

Scenario 4 (50% Carpool) LOS results for intersections and segments are provided in Tables 3.8 through 3.13. For Scenario 5 (50% Carpool with no Copper Concentrate Truck Traffic), LOS results for intersections and segments are provided in Tables 3.15 through 3.20. Tables 3.7, 3.14, and 3.21 present a traffic volume comparison between Project and non-Project related traffic for the Operations Year 5 analysis. Operations Year 5 lane configurations and LOS values for the study area under each scenario are illustrated on Figures 2 through 13.

Scenario 3 – No Carpool

Non-Peak Season For the non-peak season, the traffic forecast results indicate that all LOS criteria values, including intersections and segments, increased due to the Project related traffic under Scenario 3. For intersections, there was an average 54.62% increase in ICU values compared to values with the Project not in operation. As expected, the main increase in ICU values was observed for the intersection of AZ-83 and East Hidden Valley Road. This intersection also showed the highest ICU values. This intersection was designated as the access road to the Project Site for the purpose of this study. Although the overall intersection LOS was at level of A, it is important to note that for the East Hidden Valley Road eastbound approach, the LOS result showed a level of C during weekday AM and PM peak periods (see Attachment 1). This implies traffic turning left/right onto AZ-83 from East Hidden Valley Road would have difficulty making proper turning movements, suggesting the need of mitigation. All the intersection and segment operation levels were at acceptable LOS values for Scenario 3 during Operational Year 5 (Tables 3.1, 3.2, and 3.3).

Peak Season Although ICU values for most of the intersections slightly increased compared to non-peak season values, similar intersection LOS patterns were observed during the peak season when compared to the non-peak season for Scenario 3 during Operations Year 5. Furthermore, the ICU increased by 52.30% compared with the no Project condition. For segment LOS results, all LOS’s were at an acceptable level.

Traffic Volume Comparison In order to distinguish the increase in traffic due to population growth versus the Project operation, a traffic volume comparison was completed for Operations Year 5. Table 3.7 summarizes the number of vehicles for the base volume [i.e., Existing Year (2008)] and the predicted number of vehicles related to population growth and the Project. As shown in Table 3.7, the percentage of traffic due to the Project at Operations Year 5, under Scenario 3, ranged from 54.16% to 69.04 % with an average of 57.22%.

Scenario 4 – 50% Carpool

Non-Peak Season The traffic forecast results indicate that all LOS criteria values, including intersections and segments, increased due to Project related traffic under Scenario 4 – 50% Carpool. For the intersections, there was an average increase of 35.52% in ICU values compared to values with the Project not in operation. Similar to Scenario 3, the main increase in ICU values were observed for the intersection of AZ-83 and East Hidden Valley Road. All the intersection and segment operation levels were at acceptable LOS values for Scenario 4 during Operational Year 5 (Tables 3.8, 3.9, and 3.10).

Traffic Volume Comparison Similar to the previous section, a traffic volume comparison was prepared to distinguish the increase in traffic due to population growth versus the Project operation. Table 3.14 summarizes the number of vehicles for the base volume [i.e., Existing Year (2008)] and the predicted number of vehicles related to population growth and the Project. As shown in Table 3.14, the percentage of traffic due to the Project at Operations Year 5, under Scenario 4, ranged from 35.38% to 57.82% with an average of 45.54%.

Scenario 5 – 50% Carpool with no Copper Concentrate Trucks

Non-Peak Season For Scenario 5, the LOS analysis results closely followed those of Scenario 4. Traffic counts between these two (2) scenarios differed only in four (4) trips due to the reduction of copper concentrate trucks). As expected, the traffic forecast results indicated that all LOS criteria values, including intersections and segments, increased due to the Project related traffic under the Scenario 5 – 50% Carpool with no Copper Concentrate Trucks compared to values with the Project not in operation. For the intersections, there was an average increase of 34.99% in ICU values compared to values with the Project not in operation. Similar to Scenarios 3 and 4, the main increase in ICU values were observed for the intersection of AZ-83 and East Hidden Valley Road. All the intersection and segment operation levels were at acceptable LOS values for Scenario 5 during Operational Year 5 (Tables 3.15, 3.16, and 3.17).

Peak Season Similar to the non-peak season analysis results, the peak season LOS results also showed a close pattern to the Scenario 4 peak season LOS analysis results. For the intersections’ LOS, an average increase of 36.84% was observed in ICU values when compared to values with the Project not in operation. As expected, the average increase in ICU values during the Weekday (44.28%) was higher when compared to the Weekend value (29.39%). For segment LOS results, all the LOS values were at an acceptable level.

Traffic Volume Comparison Similar to the previous section, a traffic volume comparison was prepared to distinguish the increase in traffic due to population growth versus the Project operation. Table 3.21 summarizes the number of vehicles for the base volume (i.e., Existing Year (2008)) and the predicted number of vehicles related to population growth and the Project. As shown in Table 3.21, the percentage of traffic due to the Project at Operations Year 5, under Scenario 5, ranged from 34.94% to 57.49% with an average of 45.13%.

4.0 Operations Year 20 As described in Section 2.0, Operations Year 20 represents the Project’s operational condition at the beginning of Year 20. In order to fully analyze potential Project traffic impacts on AZ-83 and on the selected intersections, LOS results were compared to LOS values with the Project not in operation. Similar to Section 3.0, three (3) scenarios, No Carpool, 50% Carpool, and 50% Carpool with no Copper Concentrate Truck Traffic, were considered for the Operations Year 20 analysis. SYNCHRO and HCS2000 worksheets for Operations Year 20 are included in Attachments 3 and 4, respectively. Tables 4.1, 4.2, 4.4, and 4.5 present the study intersections’ corresponding ICU values and the LOS for Operations Year 20 during non-peak and peak seasons under Scenario 3 (No Carpool). Tables 4.3 and 4.6 describe the highway segment categories, corresponding LOS criteria values, and the LOS for Operations Year 20 under Scenario 3. Scenario 4 (50% Carpool) LOS results are provided in Tables 4.8 through 4.13. Tables 4.15 through 4.20 present intersection and segment LOS analysis results for Scenario 5 (50% Carpool with no Concentrate Truck Traffic). Tables 4.7, 4.14, and 4.21 present a traffic volume comparison between Project and non-Project related traffic for Operations Year 20. Operations Year 20 lane configurations and LOS values for the study area are shown on Figures 14 through 25 for each of the three (3) scenarios.

Scenario 3 – No Carpool

Non-Peak Season Under Scenario 3, average ICU values increased significantly for all seven (7) intersections by 48.93% and 45.68% for weekday and weekend periods, respectively, when compared to ICU values with the Project not in operation. Despite the increase in ICU values, traffic forecasts for the non-peak season were shown to operate at acceptable LOS values for all intersections under Scenario 3, Operations Year 20 (see Tables 4.1 and 4.2). Except for the intersection of AZ-83 and East Hidden Valley Road, all intersections had an LOS of A. This intersection, however, showed a LOS of B with an ICU of 55.3%. A detailed look at the approach LOS for this intersection gave a LOS of C for the eastbound approach leg. This implies that vehicles turning onto AZ-83 from East Hidden Valley Road would have difficulty with turning movements even though the overall intersection performance has a LOS of A. Segment LOS during the weekday PM peak period gave a LOS level of D for both Segment 1 and 2. Based on the segment LOS criteria during Weekday AM Peak period, Segment 2 gave the highest value of 71.1% compared to all other non-peak analysis periods.

Peak Season For Operations Year 20 under Scenario 3, all the intersections were at acceptable operational levels for the peak season. An average of 45.68% increase in ICU values was observed compared to conditions without the Project. Even for the most active intersection of AZ-83 and East Sahuarita Road, where the ICU values were the highest (60.4% during PM peak hours), the approach leg for turning movements showed a LOS of B or higher. Similar to the non-peak period, the intersection of AZ-83 and Hidden Valley Road showed significantly higher values. Except for Segment 1 during the Weekday PM peak period, most of the segment LOS values showed an acceptable level of C. Although Segment 1 during the Weekend PM peak period was at a LOS level of C, the LOS criteria value was close to a level of D, indicating a condition close to the traffic failure point.

Traffic Volume Comparison In order to distinguish between increases in traffic due to population growth versus the Project operation, a traffic volume comparison was completed. Table 4.7 summarizes the number of vehicles for the base volume [i.e., Existing Year (2008)] and the predicted number of vehicles related to population growth and the Project. As shown in Table 4.7, the percentage of traffic due to the Project at Operations Year 20, under Scenario 3, ranged from 38.57% to 59.03% with an average of 47.81%. Although the average value is lower than Operations Year 5 for this scenario, the results still indicate a higher percentage of traffic due to the Project operation.

Scenario 4 – 50% Carpool

Non-Peak Season As shown in Tables 4.8 and 4.9, traffic forecasts during the non-peak season for all intersections are expected to operate at acceptable LOS values under Scenario 4 for Operations Year 20. Increases in ICU values were observed when compared to Operations Year 5. For the intersection of AZ-83 and Hidden Valley Road, the overall intersection LOS values showed a level of A with an approach LOS of B for turning movements onto AZ-83 during all analysis periods. For segment analysis results, although an increase in LOS criteria values were observed compared to Operations Year 5 under same Scenario 4, all the segment LOS values were at an acceptable level of C.

5.0 Mitigation Most public agencies strive to achieve and maintain a LOS of C or greater in their jurisdiction. Therefore, when LOS results come close to or below a level of C, mitigation measures are recommended. In the previous Traffic Study Report (April 2009), total of two (2) potential mitigation methods were discussed when LOS values showed a level of D or worse. The most cost effective and easiest mitigation measure to implement is proper carpool management and staged truck deliveries such as those indicated in the Mine Plan of Operations and Feasibility Study. The Scenario 1 (100% Carpool), presented in the April 2009 Traffic Study Report, is a good example of this mitigation. The LOS analysis results under Scenario 1 showed all LOS values at an acceptable level for Operations Year 5 and 20, thus indicating an effective mitigation measure of LOS improvement under proper carpool management.

The other mitigation method identified includes roadway modifications to AZ-83 such as adding a passing lane(s). The mitigation analysis presented in the April 2009 Traffic Study Report of adding a passing lane(s) showed less improvement compared to carpool management. For example, mitigation analysis for Operations Year 20, for Scenario 3 during the peak season weekday PM peak period, showed approximately 80% of Segment 1 (AZ-83) needed to be converted into passing lanes in order to achieve an acceptable operation level of LOS C (see Attachment 5). This will require significantly high construction costs as well as numerous other considerations such as environmental issues and roadway design restrictions. Furthermore, with possible negative traffic impacts during construction of the passing lane(s), an in-depth assessment should be conducted when considering this type of mitigation measure. From a cost-benefit analysis perspective, this mitigation is not usually highly recommended as the benefit does not outweigh high invested costs.

6.0 Conclusion In this Technical Memorandum, three (3) additional scenarios were analyzed to assess traffic impacts of the proposed Rosemont Copper Project. Two (2) analysis years, Operations Year 5 and 20, were considered for comprehensive LOS evaluation. LOS analysis of intersections showed acceptable LOS for all scenarios under all analysis years. For segment LOS analysis of Operations Year 5, analysis results of all scenarios showed an acceptable level of C. Operations Year 20 segment LOS analysis results demonstrated that Segment 1 (along AZ-83) tends to be congested, yielding a LOS of level D during PM peak periods. Two (2) mitigation methods, as presented in the previous Traffic Study Report (April 2009), were reviewed. Analysis results revealed the importance of carpool implementation as a mitigation measure in order to achieve an acceptable LOS.
