KEYSTONE PIPELINE PROJECT, L.P. -1- November 15, 2007 Hydrostatic Test Plan Rev. 2

1.0 INTRODUCTION

This Hydrostatic Test Plan provides an overview of the methods and guidelines for conducting hydrostatic testing operations for the Keystone Pipeline Project (Keystone). Once the pipeline is constructed, in order to assure compliance with U.S. Department of Transportation regulations, Keystone must pressure test the pipeline in accordance with CFR Part 192 requirements. The hydrostatic test contractor is required to comply with the environmental requirements of this plan and all federal and state permits and approvals, including the Project’s Biological Assessment (BA). Special requirements associated with hydrostatic test water withdrawals to protect sensitive species and habitats are included below. The project’s Construction Mitigation and Reclamation Plan provides additional mitigation measures and erosion and sediment control methods that will be implemented during construction to minimize potential impacts during construction, hydrostatic testing, and reclamation of the Keystone Pipeline Project.

2.0 HYDROSTATIC TESTING

2.1 Test Water Source and Discharge Locations Keystone plans to withdraw water from a number of surface water sources along the project route to hydrostatically test the pipeline in sections following construction. Primary and alternate hydrostatic test water sources are included in Attachment A. Keystone will obtain all appropriate permits and authorizations for water withdrawals. Water withdrawn from a source will be returned directly to the same source or nearby (within the same watershed) at the completion of testing operations. During hydrostatic test water withdrawals, the Contractor will maintain adequate flow rates in the waterbody to protect aquatic life and provide for downstream uses, in compliance with regulatory and permit requirements. In the event that primary test water sources do not contain adequate flow rates to support the hydrostatic test water withdrawal without affecting downstream uses and resources, the alternate water sources identified in Attachment A may be used. In some cases, the alternate water source may replace more than one primary water source. In waterbodies where sensitive species are located, Keystone will generally avoid withdrawal of hydrostatic test water until after August 1, unless specific approval is obtained in advance from the appropriate regulatory or resource agency(ies). Small withdrawals associated with horizontal directional drills may take place before August 1. In these cases, the withdrawal rates will be minor and the pump intakes will be screened with fine mesh to avoid entrainment or impingement of fish or debris. In areas where zebra mussels are known to occur, all equipment used during the hydrostatic test withdrawal and discharge will be thoroughly cleaned before being used at subsequent hydrostatic test locations to prevent the transfer of zebra mussels or veligers to new locations.



2.2 Filling the Mainline Pipeline

In order to obtain water from the surface waterbody, a fill pump will be placed at the waterbody’s edge and connected to a hydrostatic test fill line (approximately 6- to 10-inch diameter steel pipe or hose) placed along the ground and attached to the hydrostatic test header. If there is not an adequate depression in the river bottom, it may be necessary to dig a small sump to allow the pump intake to be fully submerged. The intake of the pump will be screened to prevent entrainment of debris and fish. The fill pump will be placed in a plastic-lined bermed or metal containment to prevent spills or leaks from reaching the ground or the waterbody. The fill pumps will be continuously monitored during operation. Keystone anticipates that water will be withdrawn at an average rate of 3000 gallons per minute through a 6- to 10-inch pipe or hose. Water withdrawal rates will be monitored to avoid significant impacts to downstream water users, resources and streamflow. The screen around the intake will be fabricated to provide an adequate surface area of fine meshed screen to reduce the approach velocity to prevent impingement or entrainment of small fish. For example, to achieve an approach velocity of less than 0.11 m/s for a withdrawal rate of 3000 gallons per minute, a #60 wedge wire screen with a mesh opening of 0.10 inches and an open area of 63% would require at least 30 square feet of screen surface area to prevent impingement or entrainment of fish with a subcarangiform swimming mode. The contractor will utilize a screen around the pump intake with a larger surface area than indicated in this example. Keystone will regularly inspect the water intake screen for entrained fish and will contact the FWS immediately if federally listed aquatic species (e.g., fish or mussels) are found impinged on the screen. Water withdrawn for hydrostatic testing will be in the pipeline for fewer than 30 days before being discharged back to (or near) the location where it was withdrawn. Additional protective measures that will be implemented during hydrostatic test water filling and discharge operations include the following:

• Keystone will obtain water samples for analysis from each source before filling the pipeline. In addition, water samples will be taken prior to discharge of the water, as required by state and federal permit requirements.

• Staging/work areas for filling the pipeline with water will be located a minimum of 100 feet from the waterbody or wetland boundary if topographic conditions permit. The Contractor will install temporary sediment filter devices adjacent to all streams to prevent sediments from leaving the construction site.

• The intake hose and screen will be kept off the bottom of the waterbody. • Refueling of construction equipment will be conducted a minimum distance

of 100 feet from the stream or a wetland. • Pumps used for hydrostatic testing within 100 feet of any waterbody or

wetland will be operated and refueled within secondary containment as detailed in the Project’s Spill Prevention, Control and Countermeasure Plan. The fill pumps will be set on a catch pan or plastic lined secondary



containment berm of sufficient dimensions to prevent any leaking fuel or lubricants from entering the water source.

2.3 Small Hydrostatic Test Sections

Selected river crossing pipe sections may be specified to be pre-tested for a minimum of 1 hour. Water for pre-testing of a river crossing section may be hauled or taken from the respective river if it is an approved water withdrawal source. Intakes for the small test sections will be screened with fine mesh, and the intake rate/volume will be quite low to prevent entrainment of fish or debris on the screen. Since the volume of water utilized in these pre-test sections of pipeline will be relatively small, the water will be discharged overland along the construction right-of-way and allowed to soak into the ground. Erosion and sediment control measures will be installed to prevent sedimentation from the discharge.

2.4 Dewatering the Pipeline

Once hydrostatic testing is complete, the hydrostatic test water will be returned to the same waterbody source – or to the same general vicinity – from where it was withdrawn. Discharge piping (approximately 6- to 10-inch diameter steel pipe) and an energy dissipater (usually a welded steel baffling device) would be transported to the river’s edge using equipment. The equipment will keep the energy dissipater in place during the discharge and then remove the piping and dissipater once dewatering is complete. Additional best management practices, such as the use of plastic sheeting or other material to prevent scour, will be used as necessary to prevent excessive sedimentation during dewatering.

The pipeline is constructed of all new materials and there will be no additives in the hydrostatic test water. Therefore, the project does not anticipate exceeding water quality standards. Typically, hydrostatic test water will pick up some iron oxide (rust) from the new pipe and may give the discharge water a slight red color. The energy dissipater mentioned above is designed to prevent scouring and erosion at the point of discharge.

The discharge operation will be monitored and water samples will be taken prior to the beginning of the discharge to ensure that it complies with project and permit requirements. If required by state permits, additional water quality testing will be conducted during discharge, in accordance with permit conditions.
