within ten feet of the above noted systems, an "air knife" should be utilized to a depth pre-approved by the client. It <br /> may be helpful to open up tank field manways and identify the general direction that the product lines are running. <br /> • ALWAYS HAND or AIR EXCAVATE (110%the width of the proposed hole)TO AT LEAST FIVE FEET bgs. If you are <br /> going in the same location as a previously installed point and the diameter of the new boring/well is larger, you must <br /> hand auger. In addition, if you didn't advance the "old" boring yourself, you can't assume that it is a safe drilling <br /> location. Refusal may have been encountered in the "old" location. If refusal with the hand auger is encountered <br /> prior to five feet, move to a new location. If you make three attempts without success, call office to discuss <br /> alternatives. If you can't reach the SM contact your CM or UM for further instruction. <br /> • If you encounter pea-gravel while excavating STOP. Call the Miller Brooks SM for further instruction. Utilities or <br /> USTs may be present. <br /> • If you hit/damage any utility/subsurface feature IMMEDIATELY contact the office for further instruction. If you can't <br /> reach the SM contact your CM or UM for further instruction. <br /> L.SUBCONTRACTOR SHSPs <br /> All subcontractors of Miller Brooks Environmental shall be responsible for the development and implementation of their own <br /> SHSP to cover duties and hazards specific to that subcontractor's area of expertise or on-site functions.
