2.2 HEALTH AND SAFETY PLAN(HASP) CRA will prepare a HASP to protect site workers. The plan will be kept on site during field activities and will be reviewed and signed by each site worker. 2.3 UTILITY CLEARANCE CRA will mark the proposed drilling locations,and the locations will be cleared through Underground Service Alert and a private line locator service prior to drilling. Additionally,the first 5 feet of each boring will be cleared using an air-knife to minimize potential damage to underground structures not identified through prior utility locating activities. CRA reviewed Shell Oil Company as-built drawings that show the former pipelines consisted of one 8-inch line and one 10-inch line (Appendix A). The lines were spaced approximately 3 feet apart. The drawings indicate that both pipelines were removed in Section 26. The 8-inch line was removed in Section 22, however, the 10-inch line was abandoned in place. Prior to drilling, the line locator service will be used to verify the location of the 10-inch line. 2A SURVEY OF FORMER PIPELINE RIGHT-OF--WAY Prior to drilling,a licensed surveyor will survey the former pipeline ROW location and the proposed borehole locations. After drilling,the surveyor will survey the locations of any additional borings advanced during the drilling phase. 2.5 SUBSURFACE INVESTIGATION In the absence of subsurface utility conflicts, 22 soil borings will be drilled and sampled at the locations shown on Figure 3. The borings will be located approximately midway between the two pipelines (or former pipeline locations) and spaced on 300 ft intervals. The borings will be drilled using track-mounted direct push and/or hollow-stem auger drilling equipment. The proposed investigation will assess subsurface conditions beneath the former pipeline ROW where future construction activities are planned. Soil samples will be ccoaaa(ia) 2 CONESTOGA-ROVERS&ASSOCIATES
