of the MDOT ROW along eastbound I-96 for approximately 22.5 miles.Segment 3 is the proposed route from the MDOT ROW along I-96(approximately 0.25 miles west of Meridian Road) to the intersection of theexisting 8-inch diameter pipeline at Meridian Road. Each segment hasbeen assigned a milepost coordinate system running from north to south toidentify geographic features, properties, road, river, and stream crossings,and other relevant features. The Lansing Terminal is the beginning ofSegment 1 and is identified as milepost LT 0.0. Existing MDOT highwaymilepost markers MP90.8 through MP113.3 identify the MDOT I-96 ROWsegment. Segment 3 begins where the pipeline leaves the MDOT ROWapproximately 0.25 miles west of the Meridian Road overpass (nearmilepost MP113.1). This point is identified as milepost MER 0.0.Segment 1 of the proposed pipeline will be placed within a 66-footpermanent easement with an additional 15-foot temporary easement forworking room, located on various privately owned parcels. Segment 2 ofthe proposed pipeline will lie within the eastbound side of the existingMDOT I-96 ROW. The easement along Segment 3 of the proposedpipeline varies from a 50-foot to 66-foot wide permanent easement withadditional temporary easement creating a total width of 81 feet forworking space east of the Meridian Road ROW on various privatelyowned parcels.The purpose of this proposed pipeline project is to complete a pipelinetransport system that is capable of efficiently delivering refinedpetroleum products from refineries in the Chicago area and the GulfCoast area via pipelines to Chicago to distribution centers and markets ineast-central Michigan. The proposed pipeline project is needed to replaceproduction capacity and volume lost due to the closing the Total refineryin Alma, Michigan, in 1999.The proposed pipeline route is based on environmental considerations,landowner input, existing and anticipated land use, and existingright-of-ways. Alternate routes for the proposed pipeline have beenaddressed in this report. The final route of the pipeline may be slightlyadjusted as a result of final engineering requirements, easementnegotiations, and permit requirements. Additional information regardingthe environmental impacts of above ground facilities, access roads, extrawork spaces, and pipe and equipment storage yards will be prepared at alater date, if necessary.ERM2Wolverine Pipe Line Company/BR601.00.01-12/05/01Revision 1.0 – 02/04/02

1.2LAND REQUIREMENTSThe width of the proposed construction easement for Segment 1 (LT 0.0 toLT 1.5) includes 66 feet of permanent easement and 15 feet of temporaryconstruction easement for a total of 81 feet. Construction of Segment 2will occur within a 22.5-mile section of MDOT ROW along I-96 (highwaymilepost markers 90.8 through 113.3). The proposed temporaryconstruction work space along the MDOT ROW is 40 feet wide measuredfrom the highway white line bordering the right traffic lane. Thetemporary work space will be more than 40 feet wide in some locations(up to the fence line, approximately 85 feet from the white line)depending on tree cover and construction requirements. The pipelinewill be placed 33.5 feet from the highway white line or 21 feet from theshoulder of the highway in most locations. The width of the proposedconstruction easement for Segment 3 (MER 0.0 to MER 1.2) includes from50 to 66 feet of permanent easement and additional temporaryconstruction easement for a total of 81 feet.A total of approximately 170 acres of land may be temporarily disturbedduring construction. Approximately 140 acres of this total will be locatedon previously disturbed and developed land utilized for existing MDOTI-96 ROW. The permanent easement outside of the MDOT ROW will bemaintained during the operational life of the proposed pipeline. Thepermanent easement will be kept clear of woody vegetation inconformance with the Federal requirements and company standards.Approximately 20 acres of land will be included in the permanenteasement.1.3CONSTRUCTION METHODSThis section describes the proposed pipeline construction methods thatare expected to be implemented for the project.1.3.1Construction Methods and SequenceConstruction of a 22.5-mile section of the proposed pipeline (Segment 2)will occur within the MDOT ROW along the eastbound side of InterstateI-96 (highway milepost markers 90.8 through 113.3). The activitiesrequired for construction and operation of the proposed pipeline will be acombination of typical industry methods and modified techniques insensitive areas in conformance to MDOT mitigation requirements.Methods used for construction of the pipeline in sensitive areas aredetailed in Section 1.3.2.The construction phase of the proposed pipeline is expected to beginERM3Wolverine Pipe Line Company/BR601.00.01-12/05/01Revision 1.0 – 02/04/02

shortly after all of the necessary permits and certificates have been issued.After the clearing phase of the project begins, work will proceed in acontinuous manner through restoration unless inclement weatherprohibits the completion of the restoration work until the followingspring. Work may also be temporarily halted in some locations forcoordination with planned highway construction activity. Should workbe halted for any length of time, the temporary work space or easementwill be left in an appropriately stable condition. Construction of thepipeline excluding final restoration is anticipated to take approximately3 months; however, activity on any given parcel will likely besubstantially shorter.The construction sequence for this project includes the followingactivities: pre-constructionmobilizationclearing and gradingstringingpipe preparationtrenchinglowering-inbackfilling and rough gradingtestingfinal grading, restoration, and clean-upPre-construction activitiesMajor pre-construction activities will include final route adjustment,procurement of all necessary permits, easement acquisition andsurveying, materials procurement, and preparation of contract documentsfor construction, bidding and contract award. Construction documentswill include a Construction Line List that will describe specialrequirements (i.e., timber salvage, topsoil segregation, restorationmeasures, fencing requirements) required by affected landowners,MDOT, MDEQ, and other regulatory agencies.Before construction begins, a meeting will be held to: review the Applicant’s safety and environmental policies andprocedures;identify sensitive environmental areas; andpresent methods to be implemented to minimize environmentalimpacts.MobilizationERM4Wolverine Pipe Line Company/BR601.00.01-12/05/01Revision 1.0 – 02/04/02

Upon award of the contract for construction and the issuance of the noticeto proceed, the contractor will organize the construction team. Workunder this activity typically includes: 1) establishing a local constructionoffice; 2) selecting key personnel responsible for overseeing each phase ofthe construction process, and material and equipment procurement; and3) arranging for the availability of workers.Clearing and GradingThe temporary work space within the MDOT ROW and the constructioneasement outside the ROW will be cleared of all obstructions such astrees, large rocks, fencing and miscellaneous debris. A Tree LossMitigation Plan has been developed for the MDOT ROW to minimize treeremoval and replant trees following construction activities (see Section4.4). Boulders and stones will be collected and disposed of in accordancewith MDOT requirements and landowner requests. Highway signs andfencing will be carefully removed and stockpiled for reinstallation.Temporary fencing will be installed at the direction of landowners andMDOT as needed to control livestock and protect the constructioneasement from unauthorized personnel or vehicle entry.The temporary work space within the MDOT ROW and constructioneasement outside of the ROW will be prepared to provide a relatively flatsurface for safe access by construction equipment. The shoulder of thehighway and possibly the right-hand traffic lane on occasion will beclosed to public traffic for use as a construction vehicle lane to transportconstruction materials and pipe. Since a majority of the topographyalong the proposed pipeline route is flat with several areas of gentlyrolling hills, minimal grading activities will be required. No grading ortrenching will occur within the highway influence line. The highwayinfluence line includes all areas of constructed fill that provide loadbearing soils for the highway. Some grading of the MDOT ROW will benecessary outside of the influence line for construction equipment access;however, original grades will be restored at the completion of the project.Where grading will be necessary in active agricultural areas, topsoil willbe segregated from the subsoil and stockpiled along one side of theconstruction easement for reuse during restoration. The method of topsoilstripping to be used will depend on topsoil depth, current land use, andlandowner requirements.Measures to control soil erosion along the MDOT ROW are presented inSection 4.1.1 and specified in the MDOT Soil Erosion and SedimentationControl Manual (Appendix A). Grading activities associated withwetlands and stream crossings are discussed under Section 1.3.2,Construction Methods for Sensitive Areas.ERM5Wolverine Pipe Line Company/BR601.00.01-12/05/01Revision 1.0 – 02/04/02

Loading, Hauling, Unloading, and Stringing of MaterialsIngress and egress to the easement will be from the intersection of theROW and public roads, and from I-96. All loading, hauling, unloading,and stringing of materials will be done within the temporary work spaceand construction easement unless specific arrangements are madebetween the contractor and MDOT or landowners.Bending, Welding, and CoatingThese activities describe the process for preparing, connecting, andprotecting pipe segments prior to placing in the trench.Bending occurs on the construction easement prior to welding pipesegments together. All pipe segments will be bent to the desired anglebased on horizontal and vertical curves in the pipe alignment. Bendingwill occur through the use of a hydraulic pipe-bending machine. Pipesegments will then be aligned and welded. All welded joints will bex-rayed in accordance with applicable regulations and repairs will bemade as necessary.All exposed pipe surfaces, including welds, will be protected with anexternal coating. Pipeline segments will be coated at the mill, and weldswill be coated in the field. Prior to lowering-in and backfilling, all coatingwill be inspected for imperfections and repaired as required.TrenchingTrenching in upland areas will consist of excavating the trench for theproposed pipeline, and is typically accomplished with a backhoe orexcavator or a rotary wheel ditching machine. Excavated material will besidecast in a manner that minimizes erosion. The applicant willcoordinate with MDOT and landowners to minimize disruption of accesscaused by the trench during construction. Where appropriate, plugs ofsoil will be placed in the ditch or bridges will be constructed across thetrench for the affected landowner to move livestock or equipment acrossthe trench. Trenches will be sloped as necessary to provide ramps forwildlife to escape. The length of time a trench is left open will beminimized to provide a safe environment during construction.ERM6Wolverine Pipe Line Company/BR601.00.01-12/05/01Revision 1.0 – 02/04/02

To alleviate mixing of topsoils with subsoils during excavation and trenchbackfilling, topsoil will be stripped and stockpiled separately in activeagricultural land. During trench backfilling in these areas, subsoils willbe placed in the trench first with topsoil placed on the surface above thetrench to support growth of cultivated crops or natural vegetation.Depending on the time of year, groundwater or rainwater mayaccumulate within the trench. If dewatering is required, discharge willoccur into well-established, resilient vegetated areas to minimize erosion.If vegetation is not present or the risk of sediment deposition into nearbywetlands or waterbodies is evident, appropriate erosion andsedimentation control devices will be installed as required by federal,state, and local permits. Measures to control soil erosion are presented inSection 4.1.1 and specified in the MDOT Soil Erosion and SedimentationControl Manual (Appendix A).Prior to trenching, appropriate utility locating services (e.g., Miss Dig)will be contacted by the contractor to locate and mark undergroundutilities along the construction route. Where underground utilities havebeen identified or are encountered, trenching will proceed after fieldtesting determines the exact utility location. Special efforts to locateagricultural drain tiles will be made in conjunction with landowners tominimize construction-related damage. Construction procedures to beused when agricultural drain tiles are encountered, and trenchingthrough streams, rivers, and wetlands are described in Section 1.3.2:Construction Methods for Sensitive Areas.Lowering-in and Tying-inLowering-in refers to placing the prepared pipe into the trench (Figures 2and 3). Prior to placement, the trench will be inspected to ensure it is atthe specified depth. After the pipe segment is placed into the trench, thepipe will be inspected for proper alignment along the centerline withinthe trench and to ensure that the integrity of the coating has beenmaintained.On an as-needed basis, padding material will be installed on the bottomof the trench or over the top of the pipe to protect the pipe and coatingmaterial from damage due to the presence of rocks in the backfill.Backfilling and Rough GradingBackfilling activities will involve the placement of soil in the trench overthe pipe with a bulldozer and/or a backhoe. Rough grading activitieswill include replacement of any topsoil stripped from the constructioneasement during clearing and grading activities, restoration of allERM7Wolverine Pipe Line Company/BR601.00.01-12/05/01Revision 1.0 – 02/04/02

drainage ways to their original configuration, and reconstruction of theoriginal topography. In active agricultural areas, prior to replacingstripped topsoil, the construction easement may be tilled with a deeptillage device or chisel plowed to loosen compacted soils. Topsoil willthen be replaced to the original depth of removal.Hydrostatic TestingHydrostatic testing will consist of filling the new pipeline with water andpressure testing the line under controlled conditions. This process is usedto ensure the proposed pipeline’s ability to withstand pressurerequirements during normal and peak use, and to detect any leaks andimperfections in the proposed pipeline that cannot be detected by otherobservation and testing procedures. Hydrostatic testing may occur as oneoperation or in segments, depending on the construction progress andtopography.Prior to filling the pipe with water, the new pipe may be cleaned withspecial cleaning devices. Once the line is filled with water, it will betested in accordance with the applicant’s specifications and U.S.Department of Transportation regulations.Test water intake and discharge will be completed in accordance withpermit requirements. If the water source is an existing pond or flowingwaterway, the intake will be screened to prevent entrapment of fish,amphibians, and other large aquatic organisms. Adequate flow ratesand/or water levels will be maintained in the water source to protect theaquatic life and provide for all other in-stream uses. Energy dissipationdevices will be used for the discharge of test water to prevent erosion ofupland areas, stream bottom scouring, suspension of sediments, orexcessive stream flow. As required, containment structures will beconstructed to control velocity and minimize erosion. Water samplingand appropriate analysis of the discharge test waters will be conducted asrequired by applicable state or federal requirements.Finish Grading, Restoration, and Clean-UpAll roughly graded areas will be finish graded to yield smooth andcontinuous land forms. All stream banks will be shaped to match existingundisturbed grades beyond the construction easement. All miscellaneousdebris such as rocks, skids, brush, litter and any other material notoriginally present on the construction easement will be disposed off-site.Revegetation will occur based on the conditions identified in constructionpermits and in accordance with landowner requirements. For disturbedareas within the MDOT ROW, a Tree Loss Mitigation Plan has beenprepared consistent with MDOT requirements (Section 4.4). Work shallERM8Wolverine Pipe Line Company/BR601.00.01-12/05/01Revision 1.0 – 02/04/02

include but not be limited to tree planting, seeding, mulching, riprapplacement, and installation of permanent erosion control devices. Ifseasonal conditions prohibit seeding, steep slopes and stream banks willbe stabilized with erosion control matting mulched with straw, which willbe anchored in place. When favorable conditions return, seeding willresume. Details of the soil erosion and sedimentation control plan areprovided in Section 4.1.1.All highway signage will be restored to its original location. Fencing,access gates, and other vehicular barriers will be repaired or replacedacross the temporary work space and construction easement.1.3.2Construction Methods in Sensitive AreasMethods for construction of the proposed pipeline in sensitive areas aredescribed in this section. Sensitive areas typically include: land traversed by and immediately adjacent to roads and railroads;underground utilities;agricultural areas where drain tiles will be encountered;rivers, streams and county drains;wetlands; andhighway woodlots.Measures to control soil erosion and sedimentation and to mitigateother potential environmental impacts are discussed in Section 4.1. Anenvironmental inspector will be assigned to provide on-siterecommendations to implement the mitigation measures.Roads, Railroads, Rivers, and Underground UtilitiesHighways, roads, and railroad rights-of-way and streams and rivers willbe crossed by boring or directional drilling. The method of constructionwill be determined based on permit requirements of MDOT, county roadcommissions, city building departments, or by the affected railroadcompany. A minimum of 5 feet of cover will be maintained for roadcrossings and 10 to 40 feet for railroad crossings.Utility rights-of-way will be crossed by open cutting, boring, ordirectional drilling. The method of construction will be determined basedon the affected utility company. A minimum isolation distance of twofeet will be maintained.ERM9Wolverine Pipe Line Company/BR601.00.01-12/05/01Revision 1.0 – 02/04/02

When boring is performed, an excavated work area will be required oneach side of the crossing for placement of boring equipment. Safetyprecautions such as bank shoring/sloping of the trench, road crossingsand detour signs, barricades, night flashers or other devices will be usedwhen necessary. Reasonable efforts will be made to minimizeinconveniences to the public and in order to maintain safety at allhighway crossings. Directional drilling methods will be used to crossrivers, streams, and other sensitive features. Drain tile crossings d
