1.0 EXECUTIVE SUMMARY 

Overland Pass Pipeline Company LLC (Overland Pass) will hydrostatically test its proposed 759.82-mile 

natural gas liquids pipeline with pressurized water to ensure the system is capable of withstanding the 

operating pressure for which it was designed. Sections of the pipeline will be tested as a single segment 

utilizing water obtained from a combination of groundwater and surface water sources through specific 

agreements with landowners and land managing agencies, and in accordance with project plans and 

federal, state, and local regulations. 

The hydrostatic testing process will involve withdrawing water from an identified source to fill a test 

section, pressurizing the section to a pressure 25 percent greater than the maximum allowable operating 

pressure for a period commensurate with Title 49 Code of Federal Regulations Part 195. In the Platte 

River and Colorado River drainage areas, the water will be discharged back to the source waterbody by 

discharging into a straw bale structure located within 100 feet from the edge of the waterbody or, if

necessary due to permit conditions, discharging directly into the waterbody. Where water is withdrawn

from wells in Colorado and Kansas, the water will be discharged to stable upland areas along the 

construction right-of-way (as permitted) at either the eastern end or western end of a test section. These 

methods will minimize the possibility of introducing nuisance aquatic species into other watersheds, and

minimize or eliminate depletions to the waterbody or watershed. Test water will be discharged directly

into surface waters only when authorized or required by Overland Pass’ National Pollutant Discharge

Elimination System permits. Water will be discharged (as required and/or permitted) back to the source 

waterbody in all cases where feasible; this will eliminate any depletions to the watersheds, but pushing 

the water back to its source, through the pipeline may increase the length of time for hydrostatic testing. 

In some cases, water may be sprayed on agricultural fields as irrigation in coordination with landowners. 

Energy dissipation devices, as depicted in Figures 1-1 and 1-2, will be used during discharges to prevent 

erosion, streambed scour, suspension of sediments, and excessive streamflow. Sediment filtration bags 

will be used in conjunction with energy dissipation devices on PNG lands. Overland Pass will not add 

any chemicals to the hydrostatic test water. 

Overland Pass has identified potential water sources to be used for filling each pipe test section and has

been in consultation with the various agencies regarding water use. Overland Pass will continue these 

consultations, including those with the U.S. Fish and Wildlife Service (FWS) regarding water depletion 

and potential downstream impacts on threatened and endangered species if hydrostatic test water is 

removed from sensitive water resources. Hydrostatic testing will be conducted in a manner consistent

with Overland Pass’ detailed environmental plans and permit requirements. 

In order to prevent the entrainment of fish or other species of concern during hydrostatic test water 

withdrawal from waterbodies, 1/4 inch mesh will be used and installed around the intake hoses (see figure 

1-3). Overland Pass will continue agency consultations to determine if there are any additional

requirements regarding this issue. Overland Pass will attempt to avoid backwater areas, slow flow areas,

and the mouths of tributary streams when determining the location for hydrostatic intake hoses in

waterbodies. 

To minimize impacts on surface waters and to prevent erosion Overland Pass plans to discharge

hydrostatic test water using a splash pup system (see figures 1-1 and 1-2). A splash pup is a smaller 

section of pipeline welded at the end of the discharge line at a 90-degree angle. Water is discharged 

through a splash pup and into a filter bag or other sediment entrapping device, which allows the water to

be sprayed onto the ground surface within the structure or back to the source waterbody’s instream flow.

Use of a splash pup is an effective means of minimizing erosion on the ground surface and dissipating 

energy to avoid increasing the turbidity of the waterbody and causing significant changes to the flow

D-1
velocity of a river. All hydrostatic testing activities will be monitored by environmental and craft

inspectors and the outflow rates adjusted if necessary so that erosion impacts will be avoided.

The start dates for water withdrawal and hydrostatic testing are dependent on receipt of the Bureau of 

Land Management Right-of-Way Grant and project Notice to Proceed. Overland Pass currently

anticipates hydrostatic test water withdrawals to take place between January 2007 and March 2007, 

depending on construction start date and construction spread. The actual dates of withdrawal will be 

identified in the hydrostatic test water authorizations issued by the appropriate state agencies. 

Withdrawal rates from waterbodies will not exceed 0.5 percent of average monthly flow rates as 

identified by the U.S. Geological Survey (USGS), which is below the BLM recommended threshold of 

5.0 percent of flow. Overland Pass will consult with the FWS and the appropriate state agencies to obtain 

approval for the timing of hydrostatic test water withdrawals. 

2.0 WATER USE AND TESTING PLAN 

Overland Pass will withdraw a maximum of approximately 37.4 million gallons (115.0 acre-feet) of water 

for hydrostatic testing of its pipeline facilities. The water will be withdrawn from the Blacks Fork River,

Green River, North Platte River, Laramie River, North Sterling Ditch of the South Platte River, and 

private wells. In the event that withdrawals from the Blacks Fork River are too large to maintain

minimum flow rates as identified by consulting agencies and permits, Overland Pass will obtain 

hydrostatic test water from the Green River for sections 7 through 16 of Spread 1. Maps in appendix A 

depict the location of surface water withdrawal and discharge points. The pipeline testing plan will be

split by construction spread and tested in 48 sections, as depicted in figure 2-1, Hydrostatic Test

Schematic of Water Sources and Transfers. The MP range for each construction spread is as follows: 

• Spread 1: 0.0 to 150.85 

• Spread 2: 150.85 to 285.68

• Spread 3: 285.68 to 444.20

• Spread 4: 444.20 to 598.63

• Spread 5: 598.63 to 759.82

Hydrostatic test sections have been designed to maximize the efficiency of testing activities, and will 

allow for the testing of multiple sections at once. The required amount of water from each waterbody will

be withdrawn from a single point, with single or multiple pumps. Several sections will be filled from that

water source, as outlined below. Headers will be installed on both ends of each test section, and jumper 

lines will be built between each test section to transfer water into, and out of each section (see figure 2-

1). Overland Pass will attempt to reuse hydrostatic test water from one section to the next, where 

possible. 

At the end of each successful test, in the Platte River and Colorado River drainage areas, the water will be 

discharged back to the source waterbody by discharging into a straw bale structure located within 100 feet 

from the edge of the waterbody or, if necessary due to permit conditions, discharging directly into the

waterbody. Where water is withdrawn from wells in Colorado and Kansas, the water will be discharged

to stable upland areas along the construction right-of-way (as permitted) at either the eastern end or 

western end of a test section.

2.1 Blacks Fork River 

2.1.1 Water Use 

A total of approximately 2.4 million gallons (7.5 acre-feet) of water will be withdrawn for hydrostatic 

testing from the Blacks Fork River at Reference MP (RMP) 41.3, within the Blacks Fork Watershed for

the hydrostatic testing of Sections 1 through 6. The maximum targeted withdrawal rate of 1000 or 3000 

GPM, dependent upon the time of withdrawal, is approximately 0.05 to 0.13 percent of the average 

monthly flow based on USGS surface water flow data from 2000 through 2004 for the months of January, 

February, and March. Depending on the withdrawal rate of either 1000 or 3000 GPM, Test Sections 1 

and 2 will require about 28.8 or 9.6 hours to fill with approximately 1,730,299 gallons of test water, while 

Test Sections 3 through 6 will require about 12.0 or 4.0 hours to fill with 717,557 gallons of test water. 

Of the total 2.4 million gallons of water required from the Blacks Fork River, the following section break

downs are proposed: 

• Section 1, approximately 490,126 gallons (MPs 0 through 12.37)* 

• Section 2, approximately 1,240,173 gallons (MPs 12.37 through 43.67)* 

• Section 3, approximately 240,506 gallons (MPs 43.67 through 49.74) 

• Section 4, approximately 217,526 gallons (MPs 49.74 through 55.23)

D-12
2.3 North Platte River 

2.3.1 Water Use 

A total of approximately 6.8 million gallons (20.8 acre-feet) of water will be withdrawn from the North 

Platte River at approximate RMP 195.5 within the Upper North Platte Watershed for the hydrostatic 

testing of Sections 17 through 24. The maximum targeted withdrawal rate of 1000 or 3000 GPM,

dependent upon the time of withdrawal, is approximately 0.02 to 0.07 percent of the average monthly 

flow based on USGS surface water flow data from 2000 through 2004 for the months of January, 

February, and March. Depending on the withdrawal rate of either 1000 or 3000 GPM, Test Sections 17

through 24 will require about 113.0 or 37.7 hours to fill with approximately 6.8 million gallons of test 

water. Of the total 6.8 million gallons of water required from the North Platte River, the following section 

break downs are proposed: 

• Section 17, approximately 1,093,069 gallons (MPs 150.85 through 171.97)*

2.4 Laramie River 

2.4.1 Water Use 

A total of approximately 2.5 million gallons (7.7 acre-feet) of water will be withdrawn from the Laramie 

River at approximate RMP 277.1 within the Upper Laramie Watershed for the hydrostatic testing of 

Sections 25 through 32. The maximum targeted withdrawal rate of 1000 or 3000 GPM, dependent upon

the time of year, is approximately 0.05 to 0.2 percent of the average monthly flow based on USGS surface

water flow data from 2000 through 2004 for the months of November and December. (Data are not 

available for the months of January, February, or March). Depending on the withdrawal rate of either 

1000 or 3000 GPM, Test Sections 25 through 32 will require about 41.7 or 13.9 hours to fill with

approximately 2.5 million gallons of test water. Of the total 2.5 million gallons of water required from 

the Laramie River, the following section break downs are proposed:
