CC: David Krizek, P.E. (Tetra Tech)

1.0 Introduction A Technical Memorandum titled Rosemont BADCT Analysis for the PWTS Pond (Tetra Tech, 2010) was prepared in response to the April 14, 2010 Comprehensive Request for Additional Information from the Arizona Department of Environmental Quality (ADEQ) to Rosemont Copper Company (Rosemont). This request was part of the aquifer protection permit (APP) application (Tetra Tech, 2009) submitted to ADEQ in February 2009 associated with the proposed Rosemont Copper Project (Project) in Pima County, Arizona. Specifically, Tetra Tech (2010) was developed to answer item no. 21 on page 11 of 18 of the April 14, 2010 request for information.

Item 21 – Technical Memorandum – Rosemont Copper BADCT Analysis for the PWTS Ponds

Alert Level Calculations, AL1 and AL2 for the PW Pond are calculated to be 9,686 gpd and 308,813 gpd, respectively.

Rosemont's proposed alert levels AL1 and AL2 appear to be excessively high and shall be revised. Please submit new proposed alert levels. Analytical calculations should be based on system components, taking into account geomembrane defects, transmissivity of the drainage medium, design capacity of the leak collection and removal system (LCRS) rather than discharging capability of the pumping system alone at the LCRS.

An updated Technical Memorandum titled Rosemont AL1 and AL2 Analysis for the PWTS Pond (PW Portion) was prepared in response to additional comments received by Rosemont Copper Company in a letter from ADEQ titled Incomplete Response to Technical Deficiencies (dated December 3, 2010). Specifically this Technical Memorandum responds to Additional ADEQ’s Comment #10 on page 20 of 34 of the December 3, 2010 letter:

The revised alert levels are considered still too high. Pursuant to A.C.C. R-12-1206(B)(2)(a), the PWTS Dam, with 85 feet embankment height and a total storage capacity of 380 acre-feet appears to be a jurisdictional dam. The PWTS alert levels will be revised based upon the final facility design and operational requirements approved by ADWR. Please submit a copy of the ADWR approval of construction drawings and operational requirements.

This Technical Memorandum only refers to revised alert level calculations for the PW portion of the PWTS Pond based on the current design (M3, 2010).

Should design conditions change based on Arizona Department of Arizona (ADWR) considerations, these alert levels would be modified accordingly.

2.0 PWTS Pond Design The PWTS Pond is divided into two (2) cells, the Process Water (PW) Pond and the Temporary Storage (TS) Pond. The PW Pond was designed to meet prescriptive BADCT standards for a process solution pond, complete with a leak collection and removal system (LCRS). The TS portion of the PWTS Pond is a non-stormwater pond and therefore does not require a LCRS. Therefore, alert level calculations (Al1 and Al2) were only performed for the PW Pond.

2.1 PW Pond – Liner Design

The PW Pond liner system will consist of the following (from bottom to top):

A minimum six (6) inch thick layer of properly compacted bedding soil (prepared subgrade);

A sodium bentonite Geosynthetic Clay Liner (GCL);

A 60 mil High Density Polyethylene (HDPE) secondary (bottom) geomembrane liner;

A geonet or equivalent Leak Collection and Removal System (LCRS); and

A 60 mil HDPE primary (top) geomembrane liner.

A cross section of the PW Pond liner system is presented in Illustration 1.

Illustration 1 PW Pond Liner System

A LCRS will consist of a geonet or equivalent layer between the primary and secondary liners to allow any leaks through the primary liner to flow to the monitoring sump. The sump will be equipped with an automatic, fluid-level activated pump. The pump will be sized to remove fluids such that the head on the secondary (bottom) liner is minimized.

The bottom of the PW Pond will be graded to the sump at a minimum 3.0% slope to facilitate gravity collection.

2.2 PW Pond – Alert Level Calculations

The purpose of the following analysis was to evaluate the Potential Leakage Rate (PLR) through the primary liner of the proposed PW Pond and to determine AL1 and Al2. Due to the significant depth of the PW Pond at normal operating levels (41-foot depth), it was necessary to calculate the PLR’s at several levels to avoid an overly conservative calculation of the rate. This was accomplished by calculating the PLR at 10-foot intervals of depth along with the lined surface area (LSA) of the pond associated with each depth interval.

The Alert Level 1 (AL1) leakage rate is used to evaluate the liner performance in a process solution pond under typical operating conditions. The AL1, as measured by the amount of fluid pumped by the pond’s LCRS, is a low-level trigger that may indicate the presence of a small hole or defect in the top geomembrane of a double-lined, process solution pond.

The Alert Level 2 (AL2) leakage rate, as measured by the amount of fluid pumped by the pond’s LCRS, is a high-level trigger that indicates a serious malfunction of the top liner of the liner system.

The rate of liquid migration or PLR through a geomembrane liner that is not placed directly on a low permeability component can be calculated using Bernoulli’s Equation for free flow through an opening. This equation is used to calculate the ALs for double-lined process solution ponds.

wB ghaCQ 2

Where:

Q = rate of liquid migration or PLR through a geomembrane hole (cubic meters per second [m3/s]);

CB = Dimensionless coefficient related to the shape of the edges of the hole (for sharp edges CB = 0.6);

a = Hole area [square meters (m2)];

g = Acceleration due to gravity [meters per second per second (m/s2)]; and

hw = Liquid depth on top of the geomembrane [meters (m)].

The PLR calculation results are expressed as cubic meters per second per defect (m3/s/defect). This value is then converted to gallons per day (gpd) per defect, multiplied by the number of defects per acre, and multiplied by the lined surface area (LSA) of the pond in acres.

2.2.1 Calculation of AL1 for the PW Pond

The PW Pond has a total depth of 52 feet with two (2) feet of freeboard. However the pond operational level is at 41 feet (12.50 meters) which is the maximum hydraulic head (hw) on the liner to be used for calculations. The PW Pond’s LSA will be of 324,086.40 square feet (sf) or 7.4 acres. Table 1 presents the parameters and calculation results for the PLR through a single hole in the primary liner of the PW Pond that is two (2) millimeters (mm) in diameter [a = 3.14 square millimeters (mm2)] at the maximum depth of the pond.

The calculations yielded a PLR of Q = 2.95E-5 m3/s/defect. This can be converted to gallons per day (gpd) per defect as follows:

To establish AL1, the PLR is multiplied by the defect rate and then multiplied by the LSA of the pond in acres. A defect rate of one (1) hole per acre was selected. This defect rate allows for seam defects resulting from fabrication or installation factors that still may exist after intensive quality assurance (Giroud and Bonaparte, 1989). As indicated above, the PW Pond has a LSA of 324,086.40 square feet (sf) or 7.4 acres.

To account for the significant depth of the PW Pond, the PLR was calculated at 10 foot intervals and the adjusted amounts used to determine the AL1. Table 2 depicts the results of the calculation at each elevation increment within the PW Pond and the resulting leakage rate.

* Giroud and Bonaparte (1989) Based on the conditions presented, AL1 for the PW Pond was calculated to be 3,271 gpd.

2.2.2 Calculation of AL2 for the PW Pond

According to Giroud and Bonaparte (1989), a failure of the geomembrane due to poor design, or accidental punctures, may be represented by a single 11.3 mm diameter (a = 100 mm2) hole per acre. Table 3 presents the parameters and calculation results for the PLR associated with this type of defect.

The calculations yielded a PLR of Q = 9.42E-4 m3/s/defect. This can be converted to gpd per defect as follows:

* Giroud and Bonaparte (1989) Based on the conditions presented, AL2 for the PW Pond was calculated to be 104,407 gpd.

The system will be designed with the pumping capacity to accommodate the AL2 leakage rate of 104,407 gpd or 72.5 gpm. However, the Alert Level will be lowered to provide a factor of safety of 1.5 as follows:

104,407 ÷1.5 = 69,605 gpd

2.3 Flow Capacity of the Geonet Drainage Layer

Because the AL2 level for the PW Pond is very large, it was necessary to verify that the geonet drainage layer has sufficient capacity to transmit the flow to the sump

The recommended geonet for use in the PWTS Pond is PermaNet HL (High Load) manufactured by GSE Lining Technology, L.L.C. (GSE). Final selection of the geonet will be determined based on final design approval from ADWR. The specification for this product are

summarized below and detailed in the Appendix C of the Manufacturing Quality Assuarance Manual Geonet & Geocomposite Products (GSE, 2010) provide in Attachment 1. The specified geonet drainage layer for the PW Pond has a Transmissivity of 19 gallons per minute per foot at a gradient of 0.1 and a compression stress of 15,000 psf (equivalent to about 240 feet of water). This can be converted to gallons per day per foot as follows:

ftgpdday

Additionally, the following factors have been applied to demonstrate adequate flow capacity:

Creep Reduction Factor: 1.2 (based on 15,000 psf);

Clogging Reduction Factor: 1.2; and

Overall Factor of Safety: 2.0.

Therefore, the overall flow capacity is as follows:

The minimum bottom width of the PW Pond is approximately 142 feet. Therefore, the flow capacity of the geonet drainage layer can be calculated as follows:

gpdftft

gpd 000,349,1142500,9

When compared with the AL2 leakage rate of 104,407 gpd, the specified geonet drainage layer will provide a factor of safety of over 12.0.

3.0 Conclusions The ALs for the PW Pond, as measured by the amount of fluid pumped out of a LCRS for a typical process solution pond, were calculated to be:

AL1 = 3,271 gpd or 2.3 gpm;

AL2 = 69,605 gpd or 48.3 gpm; and

Pumping Capacity = 104,407 gpd or 72.5 gpm.

If it is determined during normal operations that the amount of fluid pumped back to the PW Pond from the LCRS exceeds AL1, Rosemont will take action to determine the cause. This action may include physical inspection, mechanical leak detection, electric leak location, or other methods to determine what is causing the AL1 exceedance in order to maintain the liner integrity such that the AL2 is not exceeded.

If it is determined during normal operations that the amount of fluid pumped back to the PW Pond from the LCRS exceeds AL2, the contingency plan should be followed as described in Section 8.0 of the APP application (Tetra Tech, 2009a).

1.0 INTRODUCTIONThis manual provides an overview of the GSE Manufacturing Quality Assurance Program for GSE geonet and geocomposite products. It is intended for use by GSE’s customers to enhance their under-standing of the quality system under which GSE geonet and geocomposite products are manufactured.

2.0 COMMITMENT TO QUALITY

GSE is committed to meeting or exceeding customer’s requirements and industry standards. This com-mitment to quality is established through a documented quality management system, continuous employee training, investment in technology and emphasis on process control. GSE has allocated resources to ensure that this commitment to quality translates into the best products and services for its customers.

3.0 MANUFACTURING QUALITY ASSURANCE

GSE has an on-site quality assurance laboratory at each manufacturing facility worldwide. Each facility has a fully equipped, well staffed, dedicated laboratory with strict guidelines to maintain a high level of quality and up-to-the-minute results on GSE’s finished products.

GSE has a rigorous set of minimum standards and an effective test program to assure compliance has been established. These procedures and requirements are frequently reviewed and adjusted to assure compliance with current market demands and/or predetermined project specifications. Also raw mate-rials and process parameters are controlled to provide products complying with GSE’s minimum charac-teristics and regulatory standards.

4.0 MANUFACTURING QUALITY ASSURANCE ORGANIZATION

GSE quality assurance department assures that only products meeting GSE and/or the customer's requirements are released for shipment. The quality assurance personnel are directly responsible for monitoring, testing, and providing feedback to the manufacturing department ensuring the production of the specified product quality. Each member of the quality assurance team must participate in detailed training that includes factory exposure.

The GSE quality assurance team consists of the manufacturing quality assurance laboratories, engineer-ing staff and manufacturing personnel. The combination of expertise and experience from these groups provide GSE with the proper tools to maintain the highest level of product quality and customer service in the industry.

6.0 PRODUCT IDENTIFICATION & DOCUMENTATIONA. Roll Numbering

Each roll of geonet and geocomposite is assigned a unique roll number. The quality assurance labo-ratory maintains records documenting the raw materials and resulting product quality information.

B. Approval ProcedureResults for each tested roll of product are checked against both GSE and customer’s specifications for compliance. The quality assurance laboratory approves those materials that meet these require-ments for shipment.

C. Non-ConformanceMaterial that does not meet GSE’s minimum standards or customer’s specifications is given a roll number, but is rejected and separated from the approved material. The rejected material is then identified as non-conformaning and will not be used. Material that meets GSE’s minimum standards, but does not meet a stricter customer’s specification will not be allocated to that customer, but will be placed into inventory as a GSE’s standard material.

D. DocumentationQuality assurance certificates are generated and supplied for each roll of geonet and geocomposite product to include all relevant quality assurance information about the material. The geotextile com-ponents of the drainage geocomposite materials are tracked throughout the manufacturing process. Therefore, traceability reports are available.

7.0 RECORDS RETENTIONGSE maintains reports and/or samples for products produced and sold. Records and/or samples are maintained according to GSE's standard retention policy as outlined below.

8.0 TESTING CAPABILITIESGSE maintains high capacity, state-of-the-art laboratory equipment suitable for performing the proce-dures (see Appendixes) in Houston, Texas, and Kingstree, South Carolina. Both quality assurance labo-ratories are accredited by the GAI-LAP Program. The appropriate certificates are maintained for review upon request by authorized parties.

A. Routine TestingGSE has developed a strict quality assurance program, which exceeds all industry’s standard prac-tices and/or customer’s specifications. The testing program covers raw materials and finished goods and is adhered to by all GSE’s quality assurance laboratories. The laboratory equipment used by GSE represents the most modern equipment available and it meets or exceeds the require-ments of all the test standards used. Test frequencies and the number of test specimen per sample are established based on statistical analysis and complexity of procedures.

B. Other Testing CapabilitiesIn addition to routine testing, GSE’s laboratories are equipped to perform a wide variety of other tests as required for unusual requests or product development. Further, although the GSE quality assurance laboratories are fully equipped and able to perform most routinely specified tests in the industry, there are some tests that are more economically performed by a dedicated testing facility. GSE believes requirements for such testing should be carefully considered and defined in terms of specific design requirements if they are found to be necessary.

9.0 MATERIAL QUALITY ASSURANCEGSE has established strict specifications for all raw materials and finished products. Test results must fall within the acceptable limits of GSE and customer’s specifications.

A. Raw MaterialGSE uses two types of raw materials in the manufacture of geonet products: natural resin and masterbatch. Natural resin is the base material that is used to make a geonet. It contains stabilizers to prevent degradation from occurring during and after extrusion. Masterbatch is the term referring to the concentrated carbon black material blended with the natural resin to produce the finished product. The natural resin and masterbatch are blended at the appropriate ratio at the manufactur-ing stage. The masterbatch can contain other additives depending upon the geonet product to be produced. GSE verifies the properties of each lot of raw material prior to their utilization.

When natural resin is received, samples are taken and subjected to the tests as outlined in Appen-dix A. All test data are entered into the computer database and checked for accuracy, consistency and compliance with GSE’s specifications. The material is not accepted unless all standard test requirements are met and the GSE’s test values meet the requirements set forth in the raw material specifications.

The GSE test results for each lot of resin are provided in a separate report upon request. Virgin resin is normally received in railcar lots. If resin is received by other transport and/or in other quantities, an equivalent suitable sampling procedure is provided (i.e. not less than one sample per shipment or one sample for each 50,000 lb, 23,000 kg).

In the production of geocomposite products, geotextiles laminated to one or both sides of the geonet can also be considered a raw material or component of the finished product. Quality assurance certificates are provided for all geotextile rolls bonded to the geocomposite.

B. Geonet ProductsGeonet drainage products are produced with biplanar geometry. Please see GSE geonet data sheets for test methods, frequencies and specifications in Appendixes B-E. 1. Sampling

A one foot by roll width sample is cut for quality assurance testing from every tenth roll produced. An archive sample is cut from each tested roll. This sample is taken from a random location then labeled and stored for future reference. Test frequencies and the number of test specimen per sample are estab-lished based on statistical analysis of the available data and complexity of the test procedures.

2. Evaluation of ResultsAll data are entered into a computer database for calculation and comparison to established order specifications. If materials do not meet the required GSE’s standards and/or the customer’s specifica-tions, the manufacturing personnel will appropriately make the adjustments. Only products meeting GSE’s standards and/or customer’s specifications will be approved for shipment.

3. ReportingA quality assurance certificate is issued for every roll of finished product. This report identifies the standards on which the GSE approval is based along with the actual test results demonstrated by the material.

C. Geocomposite ProductsGeocomposite products are produced by heat bonding a geotextile to one or both sides of a geonet prod-uct. Sampling evaluation of results and reporting practices are the same as for geonet products with the exception of testing for composite products. Please see GSE geocomposite data sheets for test methods, frequencies and specifications in Appendixes F-O.

D. Third Party Conformance SamplingSome specifications require independent quality assurance and/or conformance testing. GSE can provide assistance with the sampling of products by arranging for the conformance samples to be taken during production. By taking samples during production rather than on site or after production, the customer can be assured that the samples are clean and available for conformance testing in a timely manner.

GSE encourages customers to audit its manufacturing operations, to collect samples and conduct indepen-dent conformance testing prior to shipment of materials.

E. Product ShippingIt is GSE’s policy to ship only products that have been tested and approved. All shipments are packaged according to industry’s standard practices and/or customer’s specifications. Only approved handling methods are used to move rolls into and out of shipping containers, please see the GSE Installation Quality Assurance Manual for more details.
