2 Procedure No.: PA Page: 2 of 6 1. PURPOSE AND BENEFITS Tie-ins require special precautions and coordination. This procedure identifies steps to minimize safety risks associated with performing mechanical tie-ins. 2. DEFINITIONS 2.1. Tie-in A mechanical connection to an existing piping system BASF Construction Representative Individual responsible for coordinating construction activities between Operations and the Contractor. For small projects this can be the Project Engineer, or a person selected by the Project Engineer to represent the project, such as the area Mechanical Maintenance Engineer. For Maintenance work the Maintenance Planner will serve this function. For large projects a dedicated Construction Engineer is normally assigned BASF Operations Job Representative Individual in Operations responsible for overseeing jobs being implemented by Engineering or Maintenance. For Capital projects, this person is the Manufacturing representative named for the project. 3. SCOPE 3.1. This procedure applies to all tie-ins at the Port Arthur Site. For capital projects the connection can be bolt up, welded, compression fitting, or threaded. For routine maintenance connections such as temporary connections for system preparation, tie-ins that don t require hot or cold cutting of the line, etc. this procedure does not apply.

3 Procedure No.: PA Page: 3 of 6 4. PROCEDURE 4.1. The Project Engineer will generate a tie-in list identifying requirements for each tiein for approval by the Operations Job Representative. The list will include: tie-in number, line number, pipe spec, P&ID number, service, operating pressure, operating temperature, connection type. The Project Engineer will also identify any other tie-ins or work activities that should be performed in association with the tiein, with the objective to minimize plant down time. For Maintenance activities a tiein list is not required. Tie-ins which are a change to the process will require a MOC and evaluation of hazards of this change as per PA As a part of his/her job definition, the BASF Construction Representative shall arrange for the contractor to hang the tie-in tags After tie-in requirements are approved, the Operations Job Representative and the BASF Construction Representative, together with the Contractor shall field mark tie-in locations using tie-in tags available from Document Control. Tie-in tags contain the following information as shown in the Tie-in Tag Form attached to this procedure (tags are available from Document Control): Tie-in number Project or work order number P & ID Date Tie-in Tag was hung Signatures A. Person hanging the tag B. BASF Construction Representative C. BASF Operations Job Representative 4.4. When applicable, thickness checks will be done on existing piping for tie-ins The BASF Construction Representative shall coordinate all preparations necessary to perform the tie-in, including insulation removal, assembly of material needed during the actual tie-in period, temporary supports, and a temporary alternate supply such as an air compressor or generator. Care must be taken to get the proper work permits If a hot tap is required, refer to the Port Arthur Site Hot Tap Procedure All materials installed prior to the actual tie-in will be tested in accordance with site piping standards. Examples of testing are x-rays, dye penetrant testing, hydro or pneumatic testing.

4 Procedure No.: PA Page: 4 of 6 4. PROCEDURE cont d 4.8. Once Operations has prepared the system to allow for the tie-in, the work crew shall obtain a work permit. This permit identifies isolation blinds required, and all other means necessary to ensure the tie-in work is safely performed. The permit also identifies required special protective equipment such as gloves, acid suits, breathing air, etc. Special procedures such as line drilling, cold cutting, spool removal, etc. shall be listed on the permit Upon completion, the tie-in will be tested in accordance with site piping standards. All tags will be removed, and the system will be released to Operations. If a MOC was required for the tie-in a PSSR will also be required as per procedure PA Once Operations is satisfied with the work, the work crew will remove all isolation devices and Operations will put the system back in service. 5. RESPONSIBILITIES 5.1. Contractor Prepare and physically install tie-in tags Work with the Maintenance Planner to plan and schedule all field activities Execute tie-ins at identified location(s), in accordance with all applicable BASF policies and procedures BASF Construction Representative Coordinate tie-ins with Operations and the Contractor Review tie-in plans and strategies Sign off and witness the hanging of tie-in tags Inspect tie-in after completion to ensure new connection is install according to design 5.3. Operations Job Representative Ensure tie-ins have been internally reviewed/approved with-in the Operations Organization Sign off and witness the hanging of tie-in tags Coordinate preparation and isolation of the system for the tie-in work.
