HDD PA-PE-0002.0000-RD (W-L2, S-L6, W-L1)

Given the design, the threat of inadvertent return has been reduced to the maximum extent practicable and in this case that threat is considered to be low. Implementing this design, along with adherence to the Pennsylvania Pipeline Project Inadvertent Return Contingency Plan will ensure inadvertent impacts, if they were to occur, are also minimized to the maximum extent.

The drill will enter/exit 165 feet from the edge of the western most boundary of the wetland W-L2. The drill will travel beneath wetland W-L2 for 1000 feet. Using the results of the geotechnical investigation, as well as several other data points, the entry/exit, angles, and depths have been configured to pass through the best substrates while maintaining pipe integrity (e.g., no large bends). The majority of the substrate that will be passed through is estimated to be partially weathered shale. The drill will continue beneath the eastern most boundary of the wetland W-L2 and will travel 40 feet from the eastern most edge of wetland W-L2 to the western most edge of stream S-L7. The drill will pass 10 feet under the stream S-L7 starting at the western most boundary. The drill will continue beneath the eastern most boundary of the stream S-L7 and will travel 65 feet from the eastern most edge of stream S-L7 to the western most edge of wetland W-L1. The drill will pass 215 feet under the wetland W-L1 starting at the western most boundary. The majority of the substrate that will be passed through is estimated to be partially weathered shale. The drill will continue beneath wetland W-L1 and will enter/exit 115 feet from the eastern most edge of wetland W-L1.

Driving a 2.0" O.D., 1-3/8" I.D. sampler a distance of 18 inches into undisturbed soil with a 140 pound hammer free falling a distance of 30.0 inches. The number of hammer blows to drive the sampler through each 6 inch interval is recorded; the number of blows required to drive the sampler through the final 12 inch interval is termed the Standard Penetration Resistance (SPR) N-value. For example, blow counts of 6/8/9 (through three 6-inch intervals) results in an SPR N-value of 17 (8+9).

Groundwater observations were made at the times indicated. Groundwater elevations fluctuate throughout a given year, depending on actual field porosity and variations in seasonal and annual precipitation.
