5 Section 1 This handbook provides guidance and a minimum set of expectations for Oasis Midstream Services (OMS) employees and contractors regarding contractor work performed for OMS. As the contractor, you are required to follow the policies and procedures established by the contractor s company in addition to any of Oasis site-specific policies. This handbook is intended to supplement, not replace, the contractor s company safety program, which the contractor is required to implement. In the event of a conflict between this handbook and the contractor s company safety program, the more stringent rule shall apply. The contractor company s contract with OMS may be canceled, or an individual may be asked to leave OMS owned property if the contents of this guideline are not followed. 1.1 Excellence through Teamwork Environmental, health, safety, and production goals cannot be reached by operational groups operating independently. This is true for OMS as well as our contractors. While performing work for OMS, contractors will be exposed to hazards as well as operational challenges and will be expected to recognize, manage, and effectively solve and mitigate these obstacles. This is critical for our business to succeed. 1.3 How to Use the Contractor Handbook All of Oasis s contractors should have a copy of this handbook accessible to them. The contents of this handbook should be reviewed, discussed, and understood by contract personnel before any work is performed for Oasis. If an HSE issue arises that is not addressed in the handbook or by the contractor s own safety program, you must ask for guidance from the contractor representative or an Oasis representative. 1.4 How to Use the Inspector Handbook Inspectors and supervisors provide services that require additional information necessary for the quality assurance and control of various projects. Operational Specifications, map information, and other historical project scopes will be accessible to Oasis employee or contractor inspectors. 1.2 How to Use this Guidebook The intent of this handbook is to provide guidance to our contractors and employees regarding Oasis s expectations of its contractor workforce.

34 4.1 Material Transfer General Oasis Midstream Services (OMS) requires that all operations be performed in a safe and efficient manner. A major component of operating this way involves the process of handling and transporting materials. This section reviews overviews safe guidelines in order to handle and transport materials for OMS in a safe and professional manner. A) Pipe Handling 1. Prior to loading or unloading any pipe, trucks and trailers must be parked in a way that they are level and secure. Parking (hand) brakes should be set and the wheels correctly chocked. The truck s engine should be off and left in gear and the driver s location known at all times. Personnel directly involved should be the only ones within the area of pipe handling. Non-essential personnel must stay clear of work area. 2. Poly pipe becomes extremely slippery when wet. Caution should be used at all times when handling poly pipe, especially in rainy or snowy conditions. When handling this pipe in these conditions work slowly. 3. Black poly pipe becomes extremely hot when exposed to direct sunlight, therefore exercise caution and wear appropriate PPE at all times when handling black poly pipe. B) Inventory It is the responsibility of OMS personnel to oversee and take record of all equipment, pipes, and specials that enter or leave the OMS yard. This will be accomplished through internal inventory management systems. 1.A) Equipment Storage - Jobsite Storage areas should have smooth, level surfaces that are free of stones, debris and other materials that may damage pipe. If no adequate surface can be prepared, pipe should be placed on evenly spaced planking, racks, or other means of supporting and protecting pipes and equipment. Weather conditions should also be considered when storing materials that could be damaged by extreme temperatures, ice, wind, or moisture. Pipe should be separated and stored according to length and diameter as is most feasible. Piles must only contain a single size of pipe and be constructed in a pyramid shape with the bottom layer braced to prevent movement of any kind. Rows of pipe should all for easy loading and offloading of pipe by use of available loading equipment. 1.B) Off-Site Storage When storing pipe off-site, it should be placed in pipe racks according to length and diameter of pipe to prevent from rolling or falling. Pipe larger than 2 inches should be stacked with spacing strips. If pipe is stored outdoors, pipe racks should be made of material that will not deteriorate. 1.C) Indoor/Outdoor Storage 34 Construction Guidelines

35 Section 4 Black poly pipe contains more than 2% carbon black and will resist UV damage. It may be stored unprotected from UV. Other colors must be stored no longer than two years. C) Loading 1. Operator Experience Only experienced operators are allowed to use heavy equipment. This includes a verification as per OSHA standard Staging area must be clear of workers, equipment and other obstacles while material is being loaded or unloaded and must allow for clear line of sight. 2. Weight Limitations Never exceed rated lifting capacity of equipment. The proper and safe use of forklifts and other heavy equipment is the responsibility of the contractor. care to ensure that forks are not forced underneath pipe, or positioned in a way that could damage pipe racks. 2.C) Tilt Degree When tilting the load of pipe or spools tilt slightly back in order to stabilize and prevent objects from rolling or sliding forward without control. 2.D) Handling Loads When transporting a load, move with the load as close to the ground as possible, taking care to not allow pipe to drag. Drive as slowly as necessary as to avoid bouncing. 3. Front End Loaders The proper and safe use of front end loaders falls under the responsibility of the operator. 3.A) Compliance If equipped with forks, loaders are used as forklifts and treated as such. Always Never exceed rated lifting capacity of equipment. 2.A) Inspection Check forks for jagged edges/burrs. Forks set to widest setting. Always lift from center. 2.B) Fork Application Slide forks gently underneath pipe. Take maintain stability and center of gravity precautions. 4. Pipe Handling Accessories Accessories used to handle and support pipe should be properly constructed and rated above the capacity of the load that they are intended to support. Version

36 Chains, steel cable, wire rope, or hooks are not to be used to handle poly pipe. Slings must be wide band to distribute load. Nylon rope is acceptable to use with poly pipe. When the securement banding is being cut or removed, the coiled pipe has the potential to whip away from the coil. Ensure no personnel are in the area while removing these bands. DO NOT remove straps until sling is secured. Chains, steel cable, wire rope, or hooks are not to be used to handle poly pipe. Slings must be wide band to distribute load. Nylon rope is acceptable to use with poly pipe. Only specially designed pipe tongs can be used to lift poly pipe. Only specially designed pipe tongs can be used to lift poly pipe. Lifting capacities of equipment and attachments are not to be exceeded. The angle between each lifting leg must not exceed 45 degrees. 4.A) Unloading Coiled Pipe Certain precautions must be taken into consideration prior to unloading coiled pipe. When unstrapping a load of coiled pipe, it is necessary to ensure that personnel are out of line with the ends of pipe. Trailers must be level before unloading either palletized or nonpalletized coils. Never push, pull or roll coils off of trailer. Never stand behind, under or around the load as it is being unloaded. 4.B) Straight Length Pipe It is necessary to ensure the load has not shifted during transport before removing securement straps. Bundles should be unloaded with forks, forked loaders or cranes with spreader bars. Steel bands used on bundles shall not be removed until bundle is secure and stabilized in storage area (remove from ground with extension device). Never stand on a load of pipe. If breaking the banding is not possible from the ground, personnel must remove bands by the use of extension breaker bars. 4.C) Strip Loads 36 Construction Guidelines

37 Section 4 Cranes should use spreader bars to ensure proper transportation of the pipe. Do not cut bands until pipe is secure in storage. Ensure all wheel chocks are in place before beginning to unload. D) Material Return 1. Material Transfer Forms (MTF) All materials designated to arrive to, or leave from Oasis yard, must have a Material Transfer Form (MTF) completed prior to being transported. Minimum details to be included: 2.B) Bill of Lading The yard personnel will unload the material and check the material against the packing list before signing the BOL (Bill of Lading); personnel will then stage the material in a predetermined location. 2.C) Damaged Material If material is damaged beyond use/ repair, it will be cited as Condition D and billed to contractor or rejected. 3. Outgoing Material 3.A) Gate Checkout All personnel with the crews picking up All materials designated to arrive to, or leave from Oasis yard, must have a Material Transfer Form (MTF) completed prior to being transported. Lease Name / Location AFE / LOE # Person receiving materials name/ company/signature Information about who the material is for 2. Incoming Materials 2.A) Gate Check-in All vendors or contractors delivering material for OMS projects must check in at the designated gate. material must check in at the north gate. Yard personnel will receive and must have the following information before loading any material: 1. Location 2. AFE 3. Name of Oasis supervisor 4. List of material required The yard personnel will then fill out a yard Material Transfer Form (MTF) and have the person picking up the material sign it before leaving. Version

38 Yard personnel will receive and must have the following information before loading any material: Location, AFE, Name of Oasis supervisor, and the list of material required Support documents [OMS Material Transfer Form] 4.2 ROW Corridor Establishment General The corridor is established as the beginning stage of preparation for installing a pipeline. Each department has various roles to play in this development process. They are outlined below, as well as other establishment criteria. A) Engineering Develops Project Scope and Design Responsibilities 1. The OMS engineering group will develop all pressure scopes, elevation, necessary equipment, operating specifications, and other data relative to the design and operation of the proposed pipeline. B) Land department Manages Agreements and Planning Responsibilities 1. Develop and approve proposed pipeline route taking into consideration: feasibility; financial viability; topography; environmental; operational optimization; and gaining the necessary approvals from stakeholders. Record plat to county and work with other reporting and recording agencies. 2. Record plat to county and work with other reporting and recording agencies. 3. Obtain and finalize ROW agreement and landowner signoff. 4. After project completion, obtain final signature from landowner to release the project. C) Construction Department Completes the Project Responsibilities 1. Manage contractors, understand deadlines, follow regulatory guidelines, maintain quality control and review OMS programs in order to verify compliance. In addition to ensuring all documentation is maintained, remediation is accomplished if necessary, and all procedures are followed. 2. The construction department is also required to notify Land Department when a project is complete. 38 Construction Guidelines

39 Section Right of Way (ROW) Survey General The ROW is a route that is selected on a preliminary basis to determine the scope and cost of a project (determined by the engineering department). The ROW is a legal right, established by usage or grant, to pass along a specific route through grounds or property belonging to another. A) Construction Staking Construction staking will be performed with the direction of Oasis Representatives. Oasis will mark route of the centerline of the right-of-way or ROW, as well as the ROW boundaries, at the company s discretion. Oasis contractors will be responsible for staking the ditch line within the rightof-way ROW, which will be addressed in the construction folder. Stakes will be of such regularity that continuity may be maintained, normally at 100- to 200-foot intervals, along with the beginning, middle and end of all points of intersection, bores, and any/all other landowner considerations. These stakes will also be used to gauge construction progress and to reference specific locations on drawings and in reports. Contractor is responsible for submitting One Call to coordinate locating existing pipelines, sewers, water or gas mains, and electric or telephone installations. Contractor shall take all necessary precautions to protect and to avoid damage or interference with these facilities and shall repair these lines immediately if damaged. Contractor is responsible for maintaining all survey and line markers. Failure to do so will result in immediate shutdown of the job until adequate markers are maintained. B) As Build C) Mapping -Reference Section 3- The scope of mapping is transferred from survey to the Houston mapping group with all required details and info. Houston will then complete a field map with all valves, roads, crossings, landmarks, well names, etc. 4.4 ROW Construction General The Right of Way is the most permanent picture of the quality of work that OMS does. The process involved in acquiring, maintaining, and leaving the ROW are extremely important to our relationships with our stakeholders, our assets, and our reputation. A) One Call A One Call must be made prior to any digging being performed. This can be accomplished by calling 811 in both North Dakota and Montana. In Montana, it is also possible to fax-a-locate, however there must be a pre-approval process completed prior to the One Call being processed. Montana s One Call fax number: (406) and website: ( *Faxing a locate to ND One Call will only be available through the end of Dec Locate Wait Duration Version

40 After a One Call is made, line-locating personnel will arrive at the desired location within 48 hours of the One Call submission and locate any Oasis, or other entity s lines. Oasis does not authorize excavation prior to lines being located under ANY circumstances, even if at times a locate does not occur within 48 hours. The locate ticket must be followed to the exact specifications written on the ticket. B) Line Locating 1. Project Relocating & Re-spots After a line has been located, there are many things that could require a respot including: Flags being moved by landowner; Flags being moved by contractor/service provider; Uncertainty about accuracy of utility / facility markers; Change in job scope / area; One Call tickets whose territory located does not clearly indicate where the locate starts or ends. 2. Distance from Flags Minimum distance to maintain is 2 feet from any flag or utility marker, in any direction. C) HydroVaccing Hydrovaccing is the process of locating a line with non-destructive means. Water is used in lieu of shovels, excavation equipment, etc. This process uses water at high pressures to locate lines, and has the additional benefit of vacuuming, or removing the water/mud that is created in the process. All tie-ins must be hydrovacced, as well as any time a line crossing is performed. D) Relocating Locate tickets are good for 21 days only. The locate ticket will indicate the expiration of the One Call ticket Project Build Record (PBR) A) Required forms [OMS 1001] Oasis Dig Permit [OMS 1002] Anode Installation [OMS 1003] Confined Space Entry Permit [OMS 1004] Construction Summary [OMS 1005] Foreign Line Crossing [OMS 1006] Hot Tap Permit [OMS 1007] Hot Tap Info [OMS 1008] Hydro Test Data [OMS 1009] Locate Wire Installation [OMS 1010] LOTO Process [OMS 1011] One Call Log [OMS 1012] Pipe Tally [OMS 1013] Pressure Test Data [OMS 1014] Poly Report [OMS 1015] Project Build Record [OMS 1016] Steel Pipe Record [OMS 1017] Cost Estimate [OMS 1018] Measurement Change Form [OMS 1019] Final Inspection Report Preparation of Right of Way (ROW) A) Clearing It is required prior to construction that removal of brush, grass, weeds, trees, 40 Construction Guidelines

41 Section 4 crops, or anything that is on the ROW occurs. Contractor will use Brush Hog, or other sufficient means to accomplish this. B) Grading Preparing the ROW to the standard grade, side hilling, acquiring proper highs and lows to ensure your equipment gets through without issue. C) Topsoil Cut into your soil top. Location geography will determine depth of topsoil. Topsoil is moved to one side of ROW until the final step where it will be redistributed evenly. State lands require 12 inches of topsoil to be removed ROW Access Oasis Petroleum shall obtain easements for ROW s and permits for roads and railroad crossings. Contractors may only access the ROW from approved public roads and points unless specifically designated by Oasis representatives. No two-track roads will be used unless specifically authorized. Section lines can only be used with prior Oasis authorization. Settlement of any off-row damages is the sole responsibility of the contractor, specific indemnity language is written into Oasis Master Service Agreements Housekeeping A) Poly shavings Any waste materials created during the process of stringing, fusing, bending, or shaving pipe must be gathered and disposed of in the correct manner. These spare materials are not to be buried or left behind. B) Tools Tools must be kept a minimum of 2 feet from the edge from any excavation including open excavation, trench, bell hole, etc. C) Equipment Storage Equipment storage locations/laydown areas must be established prior to the commencements of Oasis projects. All agreements for additional space will be initiated by the contractor but must have Oasis approval prior to contact with landowners. The cost of these areas may be assessed only to the contractor, however, Oasis may choose to be involved or lead in the negotiation process Preservation of ROW Contractors shall offset all centerline and locating stakes in a uniform manner, as required for clearing and grading. After clearing and grading contractors shall reset the stakes in their original position. Contractors will be held responsible for the preservation of all stakes and line markers. Contractors shall bear the cost of replacing any stakes destroyed or lost and re-survey work required. 4.5 Pipelining General The method used to lay, seal and bury pipe is foundational to the success of OMS. When contractors, internal departments, and engineering groups work together as a team, projects will be Version

42 completed correctly and to the quality OMS aspires to. The following guidelines have been created with the expectation that contractors will have reference material to rely on in order to uphold and understand OMS requirements Stringing A) Quality Control OMS requests that pipe be strung along the ROW and be aligned in accordance with good pipeline construction practices using pipe furnished only by Oasis. Stringing of pipe on the ROW should done in such a manner as to cause minimal impact to the surround area, and gaps shall be left at intervals to permit use of the land and passage of farm livestock and equipment across the ROW. B) Unloading Methods Pipe is to be unloaded from the stringing trucks and lowered onto approved padded skids by using canvas slings or pipe hooks. Pipe is not to be rolled off the truck. In areas where the ROW crosses rocky terrain, special care shall the suspension of the pipe at each end during stringing operations. In instances where spooled pipe is being laid, contractor is responsible for maintaining pipe integrity. Pipe shall not be strung without Oasis approval. C) Inspection After pipe has been strung, OMS personnel and contractors will inspect it thoroughly. Contractors will reimburse Oasis for any and all damaged pipe. D) Bedding Bedding material must be clean sand or soil and must not contain stones having a maximum dimension larger than 2 inches. Material must be placed to a minimum depth of 6 inches under the pipe and 6 inches over the top of the pipe. The remaining backfill must not contain rock larger than 6 inches. Organic material and wood are not permitted for bedding and backfill since they will deteriorate over time, allowing for subsidence and subsequent shifting and possible pipe damage. It is OMS expectation that contractors will provide trained and qualified personnel to perform buttfusion operations. be taken in lowering the pipe to see that pipe is not dropped on rocks or allowed to rest on sharp or jagged surfaces. Non-ferrous pipe can be pulled provided that no visible damage occurs. A tag line will be attached to hooks to control Fusing A) General Considerations Butt-fusing operations and procedures 42 Construction Guidelines

43 Section 4 are not for novice employees. Personnel must at minimum, prior to work, understand and review manufacturer recommendations and requirements. Oasis can provide these materials if contractor does not have access to these materials. It is OMS expectation that contractors will provide trained and qualified personnel to perform buttfusion operations. The process of butt fusion joins plain end polyethylene pipes and fittings end-to-end without couplings, inserts or additional materials. Equipment must be used to hold the components in alignment and move the components toward and away from each other during preparation, heating and joining operations. The equipment includes tools to face (plane) and heat the component ends. Butt fusion equipment is manually operated for smaller pipe sizes and hydraulically operated for larger sizes. The equipment covers a range of pipe sizes and is properly set up by adjusting pipe holding clamps, setting the heating tool temperature, and for hydraulic equipment, setting the fusion joining pressure. Additional setup will be required depending on the equipment. Butt fusion equipment is set up, operated and maintained in accordance with the equipment manufacturer s instructions. Improperly set up, operated or maintained fusion equipment can produce faulty joints. Other equipment such as pipe supports and appropriate equipment for handling pipe and fittings is required. B) Butt Fusion Joining Restrictions The ends of pipes and other components such as fittings, flange adapters, MJ adapters, etc., that are joined together must have the same outside diameter and comparable wall thickness. Additional information about thickness and diameter compatibility is found below. C) Outside Diameter (OD) Compatibility Several OD controlled sizing systems are used for Poly piping components. These include IPS (iron pipe size), DIPS (ductile iron pipe size), DIOD (ductile iron outside diameter), CTS (copper tubing size), inch-od, or mm-od as applicable. For butt fusion joining, the component ends being joined must be the same outside diameter dimension and system. For example, both pipes must be the same IPS diameter, or the same DIPS diameter. Different OD sizing systems are not compatible, e.g., IPS and DIPS cannot be butt fused to each other. ID controlled (SIDR) pipes are joined using insert type mechanical fittings and are not suitable for butt fusion joining. See Reference R-WL116 for applicable PE pipe standards. D) Wall Thickness (DR) Compatibility The DR of the lower component ends must not be less than 0.79 times the DR of the higher component end. This is to ensure the quality of flow rate, and that pressures do not compromise the components connections. In order to determine if components with different DR s can be joined together, multiply the higher DR by If the lower DR is this number or higher, the components can be joined together using this procedure. Version

44 E) Fusion Quality Verification Data Logging and Testing It is recommended that hydraulic butt fusion machines be equipped with data logging technology to monitor and record time, temperature and pressure during fusion. Field fusion data logging records that compare favorably with tested trial fusion data logging records can provide confidence in field fusion quality. Data logging records must be delivered to OMS personnel at the completion of the project. for not less than one hour. Test at 73 F and 2-in/min separation rate. Ductile elongation should exceed 400% either between the fusion and the end of the gauge area, or for the entire gauge area length. If desired, the tensile yield strength of fusion test specimens and pipe parent material test specimens may be compared; however, the preferred evaluation is ductile elongation rather than tensile yield strength. The pipes and specials shall be jointed by automatic butt or electro fusion Data logging records must be delivered to OMS personnel at the completion of the project. Fusion quality is tested by preparing a trial fusion and performing destructive tests such as two D638 tensile tests, a DF2620 bent strap test, or ASTM F2634 tensile impact tests of specimens cut from the fusion. Prior to testing, test samples must be cooled to 73 F/23 C. ASTM D638 tensile tests are conducted on Type III or Type IV tensile bar specimens machined from samples cut longitudinally from each quadrant of a trial fusion with the fusion in the center of the reduced area. The sides of the tensile bar specimen-reduced area must be smooth and free from nicks and cuts. If wall thickness is reduced, the tensile specimen fused area should be from the middle of the pipe wall. After machining, condition test specimens by immersion in temperature controlled circulating air for not less than four hours or in temperature controlled circulating water welding to form a string above ground and shall be supported by smooth rollers. Three standard lengths of pipe on each side of the fusion machine require two roller supports per length of pipe. All fusion joints shall be inspected and assessed with joint record printouts from the automatic butt or electro fusion machine. Oasis personnel must approve all joints before the contractor is allowed to proceed with pipelining works. The maximum pulling length of fusion jointed PE pipes into position alongside or directly into pipe trench after fusion jointing shall not exceed 1,000 feet or length limited by the hydraulic actuator of the automatic butt fusion machine. Dragging on ground surface is strictly prohibited. All jointing of specials, tees closing lengths etc., to be conducted in the trench shall be by automatic electro fusion couplers or other electro fusion fittings. 44 Construction Guidelines

45 Section 4 ASTM F2620 includes a bent strap test for pipes having a wall thickness of 1 inch (25 mm) or less. Butt fusions may be evaluated by cutting straps from a trial fusion and conducting an ASTM F2620 strap bend test. See Figure 2. The cut through the fusion should be visually examined. Voids or dis-bonded areas are not acceptable. Strap specimens are then bent with the pipe OD or ID to the inside of the bend so that the ends of the strap touch. Failure or dis-bonding at the or unbent specimens are not reliable indicators of butt fusion quality. G) Weather Guidelines Butt fusion can be successfully performed over a broad range of field conditions. However, some weather and temperature conditions can affect equipment operation or performance, or could potentially introduce contaminants, compromising joint Joining procedures may need to be adjusted to compensate for wind, weather or temperature. fusion is unacceptable. F) Fusion Evaluation Tests Mechanical Field and Laboratory Tests ASTM standard tests and techniques such as ASTM D638 tensile tests, ASTM D1598 sustained pressure, ASTM D1599 quick burst, ASTM D1822 tensile impact and ASTM F2634 high-speed tensile impact are strongly recommended for evaluating fusion joint quality. Published ASTM testing procedures have been confirmed to produce reliable, repeatable results. Unproven, experimental, tests and techniques even those that are being developed, may be too stringent or ineffective and are not reliable indicators of fusion quality. Experimental tests should not be used until published by ASTM. Tests such as root bend tests for metal welds, bending a strap or coupon in a bench vise, bending back and forth multiple times, or hammering on bent quality. Joining procedures may need to be adjusted to compensate for wind, weather or temperature. PE pipe and fittings will expand and contract with changes in temperature. If butt fusion machine pipe clamp closure is limited, shims of elastomeric material may be necessary to secure very cold pipe against slippage. In four-clamp machines, shims should be used only in the outer clamps. 1.A) Wind Effects A windbreak or shelter should be used when jobsite wind intensity exceeds gentle breeze conditions. Wind intensity above strong breeze may require suspending fusing operations Bending A) Field-Bending Steel Pipe Version

46 46 Contractor shall make all necessary field bends required in the construction of the line except those shop bends which company shall specifically furnish. Contractor shall also fit the pipe to the contour of the bottom of the ditch, and shall restrict the arc and increase the radius of the bends to such an extent as will prevent the buckling or flattening of the pipe, weakening of welds, and will permit the free passage through said bend of an internal inspection type of pipeline scraper. All bends shall be made using a lined bending shoe so as to eliminate scratching and gouging of the pipe. Dimensions across the minimum and maximum axis of the field bends will be subject to measurement and shall not have a difference in excess of 2.53 degrees. Each field bend shall comply with the following: The bend must be smooth and uniform. On pipe 12 inches and larger an internal mandrel shall be used. After bending the pipe must be free from buckling, cracks, or any other mechanical damage and must conform to the profile of the completed ditch. There must be no wrinkle bends or mitered bends (not including deflections up to 3 degrees that are caused by misalignment). No girth weld may be placed inside the bending shoe if the weld protrudes above the outer wall of the pipe. Construction Guidelines Pipe containing a longitudinal weld must be bent so that the seam is located near the neutral axis. No bend shall be made any closer than 5 feet from the end of a joint or 3 feet from an existing girth weld. B) Field Bend Data - Steel Pipe All field bends shall be made by the cold stretch bending method, and an accurate method of measurement shall be used to determine the tolerances as follows: Trenching / Excavation A) Trenching / Excavation Permitting 1) Dig Permit Prior to any excavation an Oasis dig permit must be complete [OMS Form 1000]. Included in this permit are required action items including: ensuring the applicable state One Call system has been utilized; all potential utilities and facilities have been identified; and areas of concern hydrovacced etc. If an excavation is determined to be 48 inches or greater in depth, adequate sloping, shoring, or trench boxes must be created or installed. Other action items include: North Dakota One Call has been notified and contacts conducted to determine existence and location of underground facilities in the work area. Available records have been referenced and a plot plan indicating the location of all underground facilities has been provided and is available for reference at the job site. Have Oasis operations personnel been consulted for obtaining or discussing:

47 Section 4 Plot plans Pipeline or facility maps Lease maps Has the work area been checked for facilities/pipelines, or utility markers? And companies on markers contacted? Are there ANY signs of ground disturbance within the proposed work area? Have attempts been made to communicate with landowner to verify buried utilities? All necessary approvals, notification and agreements have been obtained. A pre-job safety meeting including JSA and emergency response plan completed? The proposed ground disturbance area(s) are identified and all underground facilities in the dig zone/search zone have been identified and incorporated into the plan. Approved techniques for exposing facilities with 2 feet of ground disturbance have been (or will be) used to verify the location of all known underground facilities. Other required Safe Work Permits have been issued (Confined Space, Hot Work, LOTO, etc.) Precautions have been taken to prevent contact with overhead power lines New non-metallic underground facilities are being installed with tracers All personnel involved in the excavation have received the appropriate training Risk has been assessed and provisions have been made to address unattended open excavations to ensure the safety of other contractors, the public, wildlife, etc. B) Daily Inspection A competent person must inspect trenches that individuals plan to enter, or could potentially enter as a part of their All trench boxes or shoring must be approved by the manufacturer to be used at the depth they are planned to be used in, for the type of material they are supporting, and must not be modified in any manner that could affect the integrity or safety of these units. Version

48 48 work scope. Trenches will be tested for: resistivity of the soil; porosity of the soil (classification test); crumbling; distance of spoil pile from trench; as well as any shoring/trench box systems. All trench boxes or shoring must be approved by the manufacturer to be used at the depth they are planned to be used in, for the type of material they are supporting, and must not be modified in any manner that could affect the integrity or safety of these units. C) Trench Boxes / Shoring Trench boxes and shoring are protective measures designed to eliminate the likelihood of a trench caving in while personnel are working inside the trench. These methods are required whenever a trench or open excavation requires an employee to work below 4 feet of depth, and proper sloping cannot be established. Trench boxes must extend a minimum of 18 inches above the edge of the trench, on both sides of the trench Lowering Pipe A) Trench Bed Condition The trench bottom shall be free from all rocks, boulders, stones or hard particles when particles, which may damage the pipe walls. The trench bed should maintain the minimum approved depth taking into consideration the contour of the land. Before any pipes or specials are lowered into the trench, they are to be inspected again for deep cuts and scratches described above. The fusion joints should also have cooled sufficiently (specified cooling time for the last joint has elapsed) before stress is imposed on any premade joints. Construction Guidelines When lowering pipe into trenches, care should be taken to avoid scoring of the pipe by contact with the sides and bottom of the trench. Special care is needed when passing under/around obstructions or other utilities. Pipe roller supports for the first four lengths of pipes from the pipe end to be lowered into the trench shall be provided. Cut section of rejected or damaged PE pipes, planks and rope shall be used for protecting the remaining pipes where appropriate, but wire ropes or chains shall not be used. B) Trench Bed Material Trench bottoms shall be layered with well-graded earth that is free from stones or hard particles larger that may damage pipe. Under no circumstances shall hot bending, in any form, be allowed on site. A distance of one foot from obstructions and other services must be maintained for the length of the pipeline. The pipe shall be kept as central as possible within the trench to enable correct side-fill compaction. Some snaking to compensate for thermal expansion of the pipe is acceptable. Pipes and fittings to be embedded in concrete shall be firmly held in position and protected from damage during pouring or compaction by a heavy-duty polyethylene sheet. Should any pipe or specials become either partially or wholly clogged before final acceptance of work, it shall be cleaned out or replaced by the contractor at his own expense. After laying the interior of pipes or specials shall be carefully cleaned to

49 Section 4 remove any debris, dirt, stones or other matter that may have entered during installation. Except when work is proceeding, all open ends of pipes and specials in the trench shall be kept closed by means of a fine wire gauge, wooden stopper or other approved means to prevent the entry of dirt, soil, stones and the like, but still allow the entry of water. C) Inspection & Testing Inspectors must look for deep cuts or scratches that gouge deeper than 10% of the pipe wall thickness. The depth of these gouges should be measured with approved depth gauges of suitable accuracy supplied or approved by OMS personnel. All damaged or flawed sections of pipe will be cut out and removed to the satisfaction of the Oasis representative before jointing according to OMS Section Welding A) General 1.A) Contractors are responsible for adhering to welding specifications and guidelines set out by ASME B B) Hot Work Permits must be completed by contractors when any hot work is performed on behalf of OMS. B) Requirements Joint design, materials, procedures and practices shall be in accordance with the latest edition of API standard 1104, Standard for welding pipelines and related facilities, ASME code B3 1.8, Gas Transmission and Distribution Piping Systems and all applicable DOT regulations.

Back-up rings are prohibited. D) Line Pipe Weld Procedures 1. Requirements With manual, shielded metal-arc butt welds, pipe with a wall thickness ¼ inch and less shall have three weld beads. Four or more beads shall be used on pipe having a thickness greater than ¼ inch. Two welders will be used to run the stringer bead on pipe 12 inches O.D. and larger. The second bead, or hot pass, shall be applied immediately after the stringer bead. Hot passes shall be completed up to and including the last completed stringer bead whenever the stringer welding is stopped for any reason and at the end of the day s work. No two succeeding passes shall start or stop at the same point. All beads are to be made by starting the pass near the top of the pipe and proceeding downward on each side of the pipe to the bottom. On any land-laid section of line not more than an interval of 25 joints shall separate the hot pass welding and the filler and cap welding processes. This interval may be reduced by Oasis inspector if conditions warrant. Before the end of the day, all cap welding shall be complete. 2. Qualifications Prior to the start of production a detailed procedure shall be established 49

50 and verified to demonstrate that welds having suitable mechanical properties and soundness can be accomplished by this procedure. The quality of the welds shall be determined by testing with the destructive tests described below. 3. Records The details of each qualified procedure shall be recorded and maintained on approved forms. This record shall show complete results of the procedure qualification tests. Similar records shall be made for all weld methods employed whether in field or shop construction. Strict compliance with these procedures shall be required during construction except where a change is specifically authorized by Oasis and its qualification recorded. 4. Procedure Specifications Contractor is responsible for maintaining specific welding procedures and welder qualifications as outlined in ASME B 31.8., however, Oasis may at times accept other standards that are equal to or more stringent than ASME B Line Pipe Welder Qualification Welders must pass all required verification tests in order to weld any OMS DOT, or other line. 6. Qualification Test Contractor shall provide only competent, skilled and qualified welders. Each welder shall be required to pass satisfactorily a test in accordance with ASME B 31.8 for each of the procedures to which he will be assigned, before being allowed to weld on the line. Oasis welding inspectors or designated qualified representatives, other than an employee of the contractor, shall witness the tests and judge the specimens. A report form describing each of the procedures and the results of each test shall be completed for each welder and submitted to the Oasis. A welder is disqualified at any time during the test if his performance is judged unsatisfactory by an Oasis inspector. 7. Equipment Contractor shall furnish all welding equipment, prepare all spools used in testing and shall bear all cost in connection with the test other than the cost of the pipe, which will be furnished by OMS. Test welds will be accomplished and the weld quality tested in accordance with ASME B 31.8, unless otherwise specified. An Oasis approved pulling machine for tensile tests will be furnished by contractor with certified gauge and calibration dates and tests. 8. Preparation For Welding Line Pipe 8.A) Welding Surfaces Welding surfaces must be thoroughly cleaned so as to be dry and free from paint, oil, rust, scale, and any other material detrimental to weld quality. Each bead shall be ground or buffed before any following weld passes are made. 8.B) Alignment 8.B.1) Joints The ends of pipe to pipe or fitting to pipe joints shall be aligned as accurately as practicable in consideration of 50 Construction Guidelines

51 Section 4 the commercial tolerances on pipe diameters, wall thickness and out-ofroundness. Methods of alignment to provide the proper size and deposition of stringer beads shall comply API standard 1104, except as noted below: Internal line-up clamps shall be used for all welded joints on pipe sizes 12-inch and larger, or where specified by Oasis, except on tie-in and other prohibitive joints. Internal line-up clamps shall be left in place until the stringer bead has been 1003 completed, unless otherwise approved by company welding inspector. External line-up clamps shall be left in place until a minimum of 503 of the stringer bead, which shall be equally spaced, has been completed. Spacing tools shall be used in conjunction with the line-up clamp to assure proper joint spacing and to permit full weld penetration. When external clamps are used, all tack welds shall be ground to ensure complete stringer bead continuity. All slag cavities, surface porosity, cold laps, starts and stops, and high points shall be removed by grinding. All slag and remaining flux shall be buffed with a power buffer between passes. 8.B.2) Rotation Of Seams Electric resistance welded pipe shall be aligned so that the longitudinal seams will be located on either side of the line within 30 degrees of horizontal. Successive joints of pipe shall be rotated to the right or left not less than 20 degrees, or have the seam located on the opposite side to avoid aligning seams on adjacent joints. Longitudinal seams on pipe bends, however, shall be located 90 degrees from the radius of the bend. On bends requiring more than one joint of pipe, longitudinal seams shall be located 180 degrees from each other. 8.C) Weather Welding areas must be protected from conditions that would impair the quality of the completed weld. At times this may require constructing a barrier wall or enclosure (provided with adequate ventilation) to protect the welds from adverse weather conditions. 8.D) Materials And Equipment For Welding 8.D.1) Electrodes - Rod or Wire Electrodes shall be in size and kind suitable for the material being welded and acceptable to Oasis. They shall conform to API standard D.2) Shielding Gases Shall conform to API standard D.3) Handling & Storage Welding electrodes must be protected from all forms of deterioration prior to actual use.

No arcing between the ground leads and the pipe will be permitted and any leads with insulation damaged to the extent that wire is exposed shall be discarded. 8.F) Inspection & Testing of Line Pipe Welds 8.F.1) Non-Destructive Testing All completed weld surfaces and surrounding areas shall be cleaned and excessive spatter must be removed prior to welding inspection. Radiographic Inspection All field welds must have a radiographic inspection completed for 10% of the weld. A larger percentage up to and including 10% of the field welds may be inspected at OMS discretion. A minimum of 10% of all field welds made within railroad or public highway ROW, river and stream crossing rights-of-way, above ground piping, and at tie-ins will be inspected for 10% of the weld. The contractor may be required to provide transportation to the job site and along the ROW as well as to provide space at the work location for equipment and personnel. Leads Magnetic particle, ultrasonic, or other non-destructive test methods may be utilized at OMS discretion. Defects All welds or portions of welds disclosed by radiographic inspection to be defective will be repaired in accordance with API 1104 at contractor s expense. Welds which are found to be defective by OMS inspectors will be cut out and tested in the method described in section 8.H of this manual. 8.G) Visual Inspection Completed welds must be visually inspected and marked as acceptable by OMS inspectors before the joint coating is applied. It will not be deemed satisfactory unless it meets the standards of acceptability and testing requirements as defined in API standard 1104 for welding of pipelines. 8.H) Destructive Tests of Field Welds Contractors will be responsible to cut out any welds as required by Oasis and deliver the sample for testing and examination, and re-weld the pipe. OMS will not require the contractor to cut out more than one non defective weld per welder without reimbursing contractor, 52 Construction Guidelines

53 Section 4 regardless of whether the weld was cut out because of the results of nondestructive testing methods (other than radiographic), visual inspection or other reasons. Coupons cut from test welds shall be pulled for tensile strength by an OMS approved pulling machine, furnished by contractor. Welds may be further tested by cutting additional coupons for bend tests and nickbreak tests and the ductility and grain structure of the welded metal examined. Contractors will replace all defective welds and one non-defective weld per welder at their expense. A record of the results of each test shall be jointly signed by an Oasis representative and the contractor. 8.I) Weld Identification Oasis shall assign a specific number to each contractor welder. It shall be the duty of each welder to personally affix such number with a permanent waterproof felt or paint marker, adjacent to each weld on which he works for future identification. In the event any welder leaves the project, his number will be voided and not duplicated when another welder is utilized. If radiographic or physical tests indicate the production of defective welds, the welder responsible shall be disqualified from further welding on the project. Should two or more welders participate in making the defective welds, the contractor, welding foreman and OMS inspector shall determine which welder was responsible for the defective work. 8.J) Replacement of Test Welds or Rejected Welds When welding the line together at places where welds have been removed, if possible, one weld shall be made after moving the line back into position; otherwise two welds shall be made by installing a spool with the minimum length of 1½ times the pipe diameter. 8.K) Repair of Weld Defects Weld defects, other than cracks, may be repaired if the weld was not previously repaired if authorized by an OMS inspector. Such defects shall be removed by grinding to clean, sound metal before re-welding and shown by radiographic inspection to be free of defects before acceptance. Should laminations, split end or longitudinal seam defects be discovered in the pipe, the full joint containing the defect shall be removed from the line. 8.L) Standard of Acceptability Minimum acceptable standards for penetration, fusion, burned-through areas, slag inclusion, gas pockets, discontinuities and undercutting shall be in accordance with API standard 1104, and ASME code. 8.M) Arc Burns Contractor shall prevent arc burns. Arc burns, where they occur, shall be cut out at contractor s expense. 8.N) Preheating & Stress Relieving 8.M.1) General Practices The welding procedure shall specify the preheating and stress relieving practices to be followed when materials or weather conditions make either or both necessary. Version
