2 No.: BCF Page: 2 of PURPOSE To provide guidelines and procedures addressing excavation requirements that must be met prior to performing excavation work in ISBL and OSBL areas. 2. SCOPE This procedure applies to the BASF Freeport plant site. 3. DEFINITIONS 3.1. Excavation: The penetration of any ground surface (concrete, dirt, gravel, etc.) by machine-driven equipment Excavation Equipment: Machine-driven backhoes, dozers, hoe rams, jack hammers, augers, power drills, power saws, etc Excavation Work: Grass stripping, power auguring, concrete drilling, concrete sawing, breaking/removal of concrete, earth removal, etc Confined Spaces (Permit Required): Work in excavations have limited means of egress* and have one or more of the following characteristics: Contain or have the potential to contain a Hazardous Atmosphere (such as having held flammable, explosive, acidic, caustic, toxic materials) or where oxygen enriched or deficient atmospheres or noxious odors may exist. Contain a material that has the potential for engulfing an Authorized Entrant. Have an internal configuration such that an Authorized Entrant could be trapped or asphyxiated by inwardly converging walls or by a floor which slopes downward and tapers to a smaller cross-section. Contain any other recognized serious safety or health hazards; such as ionizing radiation, electric shock, temperature, or moving parts. Is considered a process or storage tank/vessel. NOTE: Temporary ladders and temporary, movable, spiral, or articulated stairs may be considered a limited or restricted means of egress. Fixed industrial stairs or ladder will be considered a limited or restricted means of egress when the conditions or physical characteristics of the space, in light of the hazards present in it, would interfere with the Authorized Entrant s ability to exit or be rescued in a hazardous situation.

PROCEDURE Designate the Waste Management Coordinator. 5.1 General Requirements ISBL and OSBL excavations are to be surveyed and approved using the Form (Attachment 1) The following exceptions apply to this procedure:

7 No.: BCF Page: 7 of Hand dug excavations does not normally require an Excavation Request but must be considered on a case-by-case basis Surface maintenance work with road graders or box-blades that does not include repair or modifications below road grade does not require an The use of drills for the purpose of installing anchors or form supports that are no longer than 4" in length and 1" in diameter does not require an. A field inspection and approval from the unit is required The installation of screw anchors that require only hand power to Install does not require an. Machine installed anchors in ISBL/OSBL areas will require an and approvals from the appropriate parties Chipping concrete up to 2 inches does not require an Excavation Request unless underground obstructions exist in the work area. A field inspection and approval from the unit is required Senior Production Manager/Director (or designee) will approve ISBL excavations where no known underground hazards exist. The Civil Design Engineer will approve all other excavations Excavations within 20' of OSBL pipeline corridors, railroad tracks, utility easements and power line/pole easements or permits for any excavations that could endanger the stability of existing nearby structures will require approval by the Civil/Mechanical TES Group even if the work is within the block limits and considered to be ISBL All blocks are required to have a plot map showing all known underground hazards. The plot map shall be maintained in a current status condition at all times Probing Guidelines are listed below Use water freely to lubricate probe rod in the ground. Push probe into ground several inches and pull it out. Employee pours water in hole while standing or kneeling in front facing employee who is using 4 ft. bar and insures that pilot hole is plum. Employee then pushes probe into hole again going deeper than before and pull it back out again. Add water to hole again. Employee who starts pilot hole then moves 4 ft. probe out of the way allowing next employee who is standing to the side to use longer probe bar to

8 No.: BCF Page: 8 of Safety probe deeper. Continue this process until desired depth is reached. Required depth is 2 ft. passed excavation depth down to 9 ft Often the top inches has a nearly impenetrable crust therefore a backhoe may be used to remove this crust The pattern that will be used for probing will be a cross pattern on 2 centers that will extend 2 ft. beyond and 2 ft. below to a maximum depth of 9 ft. of anticipated excavation or ground penetration Document any obstructions found or areas where probing is not possible. Note: For pipeline excavations where lengths of excavations extend beyond a specific location, probing requirements will be determined on a case by case basis and agreed upon by the Permit Writers, Permit Accepters, Civil Engineering, Construction, and other groups involved in the excavation In normal traffic areas or where a personnel hazard exists, excavations shall be provided with standard guardrails or covers. Covers must be able to support the weight of the traffic that is expected for the area. At night, warning lights shall be provided If it becomes necessary to remove guardrails, excavations shall not be left unattended unless the area has been barricaded to keep personnel at least 5 feet away from the edge of the excavation Before opening any excavation, it shall be determined if there are any underground installation hazards or structural support needs The walls and faces of excavations 5 feet deep or more and all excavations in which personnel are exposed to danger from ground movement or cave-ins shall be guarded by an approved protective system.

9 No.: BCF Page: 9 of In excavations that personnel may be required to enter, excavated material and other material shall be effectively stored a minimum of 2 feet from the edge of the excavation Daily inspections of excavations shall be made by the job contractor s competent person and the BASF Representative in charge of the job. If evidence of possible cave-ins or other hazards are observed, all work in the excavation shall cease until the necessary precautions have been taken to safeguard employees A stairway, ladder, ramp or other safe means of egress shall be located in excavations that are four (4) feet or more in depth so as to require no more than twenty-five (25) feet of lateral travel for employees A Confined Space Entry permit will be required for all excavations where a worker s head will be required to be below ground level and where heavy gases may accumulate or get into the excavation. For more information also see section All piping within the excavation that is open-ended or has had its mechanical integrity impaired must be properly isolated to prevent material from leaking into the excavation. 5.3 s Approved excavation requests will expire three (3) months after the date of issue. If work begins within that time frame, the approved request remains in effect until work is complete. If construction has not commenced within three (3) months the excavation request will have to be re-submitted Forms should be submitted as far in advance as possible to allow for proper evaluation. Emergency excavation requests will be expedited accordingly If an emergency occurs during other than normal working hours and it requires excavation work in ISBL areas, the owning manager shall be contacted. If involvement from Civil/Mechanical TES Group or the Waste Management Coordinator is required, have Security contact the respective on-call personnel.

10 No.: BCF Page: 10 of If an emergency occurs during other than normal working hours and it requires excavation work in OSBL areas, have Security contact the Civil/Mechanical TES person on the call list and, if needed, the Waste Management person on call. 5.4 Safe Work Permits/Excavation Procedures BASF Owned/BASF Property - BASF personnel issue Safe Work Permit in conjunction with completed/approved Form BASF Owned/Outside Boundaries - Property/corridor owner issues work permit. BASF Excavation Procedures are used. Property/corridor owner may opt to have their personnel on site during excavation work, i.e. critical line(s) in area or other safety concerns Third Party Owned/BASF Property - BASF issues Safe Work Permit.
