Resource Report 1 – General Project Description 1-1 Eastern System Upgrade Project

1.0 RESOURCE REPORT 1 – GENERAL PROJECT DESCRIPTION

1.1 INTRODUCTION

Millennium Pipeline Company, L.L.C. (Millennium) is seeking authorization from the Federal EnergyRegulatory Commission (FERC or Commission) pursuant to Section 7(c) of the Natural Gas Act toconstruct, install, operate, and maintain the Eastern System Upgrade (Project). The Project includesconstruction of approximately 7.8 miles of 30- and 36-inch pipeline loop in Orange County, New York.Millennium proposes to locate a majority of the pipeline loop overlapping with and adjacent to the right-of-way associated with its existing mainline (Millennium Pipeline). Additionally, as part of the Project,Millennium proposes to construct and operate (1) a new compressor station (Highland CS) in SullivanCounty, New York, (2) additional horsepower (hp) at the existing Hancock Compressor Station (HancockCS) in Delaware County, New York, (3) modifications to the existing Ramapo Meter and RegulatorStation (Ramapo M&R) in Rockland County, New York, and (4) additional pipeline appurtenant facilities

at the existing Huguenot Meter Station (Huguenot M&R) and Westtown Meter Station (Westtown M&R)in Orange County, New York. Dependent upon receipt of necessary approvals, construction of theProject would be anticipated to commence in the Fall of 2017 to meet a target in-service date inSeptember 2018.

On January 19, 2016 Millennium requested approval from the FERC to initiate the Pre-filing NationalEnvironmental Policy Act (NEPA) Review Process for the Project. The FERC issued its approval ofMillennium’s Pre-filing request on February 5, 2016 in Docket No. PF16-3-000. The Pre-filing ReviewProcess will allow for active participation by interested stakeholders throughout the Project development

process while maintaining a coordinated schedule and ensuring the timely review and decision on the

certificate application. The Pre-filing Review Process will also allow Millennium and the FERC to haveopen communication during the planning stages of the Project and will greatly improve the FERC’sability to identify issues early and address them as part of its environmental review assessment. Uponcompletion of the Pre-filing Review Process, Millennium will file an application with the Commission fora Certificate of Public Convenience and Necessity to construct, install, operate, and maintain the Project.

The FERC’s comprehensive NEPA review process requires an applicant to submit an EnvironmentalReport consisting of up to 13 individual resource reports. Each resource report addresses a particularaspect of the environment in the Project area and evaluates the potential effects of the construction andoperation of the Project on that particular aspect. This Resource Report 1 (General Project Description)identifies the purpose and need for the proposed Project, the locations and descriptions of Project

facilities, and the land requirements associated with the construction and operation of the proposedfacilities. This report also discusses: the proposed construction procedures; construction schedule; workforce, operation and maintenance procedures; potential plans for future expansion of the proposedfacilities; agency consultation and landowner notification; permits and approvals required to construct andoperate the Project; status of field surveys; proposed non-jurisdictional facilities; and an assessment ofcumulative impacts from other reasonably foreseeable future projects.

Natural Gas Capacities

Station ID Installed Horsepower

Corning Compressor Station 15,900

Hancock Compressor Station 15,900

Minisink Compressor Station 12,260

The Millennium system is directly connected to five storage facilities and 14 interconnecting interstate

and intrastate pipelines. The Millennium system serves customers along its route in the Southern Tier of New York and helps meet the energy needs of Northeast markets.

A checklist showing the status of the FERC filing requirements for Resource Report 1 is includedfollowing the table of contents. Required drawings and maps showing the proposed Project facilities arelocated in Appendix 1C. Refer to Figure 1.1-1 for a Project overview map that shows the location of all

proposed facilities and their association with Millennium’s existing pipeline facilities.

1.2 PURPOSE AND NEED

The purpose of the Project is to permit Millennium to transport an incremental volume of approximately200,000 dekatherms per day (Dth/dy) of natural gas from Millennium’s Corning Compressor Station to anexisting interconnect with Algonquin Gas Transmission, L.L.C. located in Ramapo, New York. All of thenew capacity is subscribed under long-term, firm contracts. Therefore, the Project is needed to meet thisexpress market demand for new natural gas transportation capacity.

The Project facilities have been specifically designed to meet the demand for an additional 200,000Dth/dy of firm transportation, as well as to maintain current operating pressures at intermediate delivery

points following the construction of the Project, to continue to meet customer demand on Millennium’ssystem during the summer months, and to ensure continued deliveries to interconnecting pipelines.

1.3.1 Pipeline Facilities

The Project includes approximately 7.8 miles of 30- and 36-inch diameter new natural gas pipeline loop(Huguenot Loop) that will extend from an interconnection with the existing Millennium Pipeline at theexisting Huguenot M&R Station in the town of Deerpark, New York, extending southeast through thetown of Greenville, to an interconnect with the Millennium Pipeline at the existing Westtown M&RStation in the town of Minisink, New York. Table 1.3-2 provides a summary of the Huguenot Loopincluding milepost (MP) designations within each town. All MPs throughout this report refer to locationsalong the proposed Huguenot Loop, unless preceded by “Millennium”, which denotes an MP locationalong the existing Millennium Pipeline. The Huguenot Loop will have a maximum allowable operating

pressure and a maximum operating pressure of 1,200 pounds per square inch gauge. To the extent practicable, the Huguenot Loop will be constructed overlapping with and adjacent to the permanent right-of way associated with the existing Millennium Pipeline. Based on current design, approximately 94

percent of the total length of the new pipeline will be co-located with Millennium’s existing rights-of-

way. Tables 8A-3 and 8A-4 in Resource Report 8 will identify existing rights-of-way adjacent to theHuguenot Loop and locations where the Huguenot Loop would be more or less than 25 feet from theexisting Millennium Pipeline, respectively [Note: Not Included in the draft].

Compressor Stations1.3.2.1

Highland CS (New)

The Highland CS is a proposed, new compressor station located in Sullivan County, approximately 25miles east of the existing Hancock CS in Delaware County. Millennium proposes to install one 22,400 hpSolar Titan 130E compressor at the new station.

The auxiliary facilities will include the compressor building, and will be constructed of a rigid steel framewith sheet metal roofs and walls. A controls building and an auxiliary building will house station controlsand communications equipment as well as an emergency electrical power generator and compressed airsystem. The proposed facilities will also include valves, a fuel gas heater, parking and access areas, and afence enclosure. Utilities that will be supplied from local utility companies are electric power andcommunications circuits. These utilities will require minor construction to bring the services into the

station property. No new utility right-of-way is anticipated to be needed. The station site work willinclude a self-contained on-site water well and sanitary sewer system (e.g., on-site septic).

The site for the Highland CS has several thousand feet of frontage on Route 12/55; however, the facilitywill be set back from the road far enough so that the grade of the terrain and existing wooded vegetation

provides adequate visual screening for the facility from the road. No additional screening is proposed.The outdoor lighting for the new compressor station will be limited during un-manned night timeoperation to the minimum amount required for security. The station security system incorporates outdoorvideo cameras that must have sufficient outdoor lighting to record clear images at night. The station maingate along with the station yard and all building entry and exit doors will have lighting for security.These lights will have directional control or they will be positioned in a manner that minimizes theirvisibility in the direction of local residences.

Hancock Compressor Station (Modified)

Millennium proposes to add a new Solar Titan 130E compressor unit, totaling 22,400 hp and to re-stagethe existing Solar Mars compressors (15,900 hp) at its existing Hancock Compressor Station in DelawareCounty, New York. Installation of the new compressor unit will require construction of a newcompressor building and auxiliary building. The modifications will also include installation of gas after-coolers; filter separator; additional MCC cabinets; fuel gas heater; valves, etc., some of which may be

built outside of the current station footprint. Minor construction will be required to upgrade the existingelectric power utility service into the station, but no new rights-of-way are required for the upgrade. Noadditional visual screening is planned beyond existing on-site visual screening. The outdoor lighting forthe existing compressor station is limited during un-manned night time operation to the minimum amountrequired for security. The station security system incorporates outdoor video cameras that must havesufficient outdoor lighting to record clear images at night. New outdoor lighting may be required in thearea around the new compressor building. If new lights are installed, the lights will have directionalcontrol or they will be positioned in a manner that minimizes their visibility in the direction of localresidences.



19/184


Meter Station1.3.2.2

Huguenot Meter Station (Modified-MP 0.0)

Work at the existing Huguenot M&R will include the removal of the existing Millennium 30-inch pipeline receiver stub-up piping assembly and the extension of the 30-inch Millennium pipeline across themeter yard and ultimately to the new 30-inch receiver facility located at MP 0.0. Work will also includethe installation of new regulator facilities to reduce the MAOP from the existing Millennium 30-inch

pipeline (1,200 psig) to the existing Millennium 24-inch pipeline (936 psig), and the installation of a new permanent 24-inch pig launcher to the existing Millennium 24-inch launcher stub-up piping assembly.All new facilities will be located within the existing Huguenot Meter Station site except for the extensionof the 30-inch pipeline to the new pig launcher / receiver at MP 0.0.

Westtown Meter Station (Modified)

Work at the existing Westtown M&R will include the installation of a new 36-inch pig receiver at theterminus of the new 36-inch Huguenot Loop line. The existing Westtown M&R site will be expanded byadding a 35 foot wide by 125 foot long extension to the west side of the existing Westtown M&R fenced-in site. Work will also include the installation of a new 24-inch pig receiver to the existing Millennium24-inch pig receiver stub-up piping assembly and a new 30-inch pig launcher to the existing Millennium30-inch pig launcher stub-up piping assembly, all within the existing Westtown Meter Station site.

Ramapo Meter Station (Modified)

The existing Ramapo Meter Station is located at Millennium’s interconnect with the Algonquin GasTransmission, LLC (Algonquin) pipeline system approximately one half-mile southwest of the Algonquinright-of-way crossing of Sky Meadow Road in Ramapo, New York. The proposed modifications would

be generally located within the limits of the meter station facility and includes a new filter/separator, over pressure protection / back feed to existing facility, in-line heater, and ultrasonic meters and flow/pressurecontrol valves to control the required capacity of natural gas through the station.

Millennium intends to use the permanent access road to the station for the period of construction and foroperation. Millennium is currently in the process of upgrading this access road for its operational needs.Millennium is also currently in the process of obtaining a permanent easement from Orange County for

placement of the new filter/separators and / or other new equipment including but not limited to new

meters, heater, flow and pressure control regulation.

Additional Aboveground Facilities1.3.2.3

Launcher and Receiver (MP 0.1)

A new 65 foot wide by 150 foot long fenced in facility will be installed along the existing Millennium 24-inch pipeline right-of-way at MP 0.1 and will include a new 30-inch pig receiver and a new 36-inch pig



20/184


launcher for the Huguenot Loop. This new facility site is required because there is insufficient room atthe existing Huguenot M&R to accommodate the new receiver / launcher facilities. The new facility islocated partially within Millennium’s existing / proposed permanent easement. A launcher/receivertypical detail is included in Appendix 1C [Note: Not included in this draft].

Alternate Interconnect (MP 7.5)

A 12-inch side tap will be installed on the 36-inch Huguenot Loop and tied into the 12-inch ValleyLateral to provide an alternate interconnect to supply gas to the Valley Lateral in the event that the 24-inch Millennium pipeline is taken out-of-service. This facility will be a below grade valve with only anextension stem/wheel operator located above grade. There will be no security fence or crushed rock atthis location. It will be located on land owned by Millennium and currently maintained for the existingMillennium Pipeline right-of-way.

All pipeline facilities and associated appurtenances will be designed, constructed, tested, operated, andmaintained to conform to or exceed the requirements of the U.S. Department of Transportation (USDOT)in 49 Code of Federal Regulations (CFR) Parts 191 and 192, Transportation of Natural and Other Gas byPipeline, Minimum Safety Standards, Annual Reports, Incident Reports, and Safety-related ConditionReports; 18 CFR § 380.15, Site and Maintenance Requirements; and other applicable federal and stateregulations.

The pipeline will be constructed of carbon steel pipe that has been manufactured in accordance with theAmerican Petroleum Institute’s (API) specifications for seamless and welded steel line pipe for use inconveying gas in the natural gas industries (API 5L) with a fusion-bonded epoxy coating.

1.3.4 Status of Field Surveys

Detailed civil, biological and cultural field surveys began in October 2015 within a 100- to 300-foot-widesurvey corridor to accommodate the construction/permanent rights-of-way, ATWS, and minor routerealignments that may be required for site-specific features. Environmental components of the survey

program include delineations of wetlands and waterbodies, identification of threatened and endangeredspecies or their habitat, surveys for cultural resources within the area of potential effect, and identificationof nearby water supply wells and residences.

As of February 1, 2016 civil, biological, and cultural surveys have been completed on land where survey permission has been granted (approximately 83 percent of the construction right-of-way, the pipe /contractor yards, staging areas, and all access roads). More detailed information on the methodologiesused, and the status and results of surveys completed to date will be included in Resource Report 2 (WaterUse and Quality); Resource Report 3 (Vegetation and Wildlife, including threatened and endangeredspecies); and Resource Report 4 (Cultural Resources) in the draft Environmental Report to be submittedin April 2016. A summary of non-surveyed areas for the Project is included in Table 1.3-4.

1.4 LAND REQUIREMENTS

Construction and operation of the pipeline loop will require acquisition of construction work areasconsisting of the temporary construction right-of-way, ATWS, access roads from public roadways to theconstruction work areas, pipe / contractor yards, and staging areas. Following construction, all

construction work areas will be restored and revegetated. Millennium will increase its existing permanenteasement by 25 feet to accommodate operation of the Huguenot loop. For portions of the Huguenot Loopthat are not co-located with the existing Millennium Pipeline, a new 50-foot permanent right-of-way will

be obtained for operation of the new pipeline loop.

The following sections describe the various components of the construction work areas and land that will be maintained for operation of the Project.

Construction Right-of-Way1.4.1.1

Appendix 1C includes typical right-of-way cross-sections for construction in uplands, agricultural land,and wetlands [Note: Not included in this draft]. Millennium is proposing to use a construction right-of-way width that will provide for safe working conditions and efficient pipe installation while also

protecting sensitive environmental resources. The dimensions of Millennium’s typical constructionrights-of-way are based on the following considerations.

• Construction Work Area: The equipment work area typically will require approximately125 feetfor efficient pipe installation and to accommodate:

o Automatic welding – Millennium may use automatic welding to weld the pipe jointstogether before lowering the pipe into the trench. This involves use of portable shelters,commonly referred to as “sheds” or “shacks,” that are leapfrogged down the right-of-way



24/184


by sidebooms during mainline welding operations. The standard width of these sheds is between 10 and 12 feet, not including maneuvering room for the sideboom to move thesheds down the right-of-way.

o A travel lane – The travel lane is essential for efficient pipeline construction and allowsequipment and support crews to pass around construction activities. During pipe layingactivities, the travel lane allows sidebooms to leapfrog along the right-of-way, allowingfor longer segments of pipe to be installed. For short distances and in environmentallysensitive areas, the travel lane can be reduced, although ATWS is often required outsideof the sensitive areas for pipe makeup and/or spoil storage.

The majority of the Huguenot Loop is co-located with the existing Millennium Pipeline in this area.Typically, Millennium will utilize 45 feet of the existing permanent right-of-way for the MillenniumPipeline and an additional 80 feet of new construction right-of-way for the Huguenot Loop.

The construction right-of-way width and temporary land requirements for installation of the pipeline willdiffer according to the type of terrain encountered, construction methods that will be used, andenvironmental sensitivity of the land being crossed. The typical right-of-way cross-sections are providedin Appendix 1C [Note: Not included in this draft]. Based on construction experience involvingcomparable installations, and evaluation of the environmental sensitivity of the land being crossed,Millennium is proposing use of the following typical construction right-of-way widths:

• 175 feet in agricultural land (i.e., full right-of-way topsoil segregation);• 125 feet in upland areas;• 75 feet in wetland areas; and• Up to 185 feet in areas of steep side slope.

Table 1A-1 summarizes the locations, by milepost, where the standard construction right-of-way would be 175, 125, 75, or 185 feet wide [Note: Not included in this draft].

Additional Temporary Workspace1.4.1.2

ATWS will be required where an obstacle prevents the normal placement of spoil and the placement of pipe sections immediately adjacent to the pipe trench (for example, at a waterbody crossing or roadcrossing), where additional volumes of spoil will be generated in areas where a reduced right-of-way is

being used (for example, at wetland crossings), or where additional construction operations will be performed (for example, at HDDs).

ATWS typically will be required on both sides of road, wetland, and waterbody crossings, at truckturnarounds, at hydrostatic test water withdrawal pump locations, at pipe tie-ins, at HDD entry and exit

points, at foreign pipeline or other utility crossings, and for staging and fabrication of drag sections. Thesize and configuration of each ATWS is unique and dependent upon the existing conditions at each worklocation (e.g., available or accessible space, the presence of buildings and other structures, crossing angle,



25/184


crossing depth, length of crossing, terrain, or the presence of trees or sensitive habitat). See Table 1A-2for the proposed location and purpose of each ATWS [Note: Not included in this draft].

Access Roads1.4.1.3

Access roads are used to transport construction workers, equipment and materials to the constructionwork area from public interstate, state, county and local highways/roads. These access roads include

private roads and/or two-tracks that may require minor modification or improvement to safely support theexpected loads associated with the movement of construction equipment and materials to and from the

public roadways to the construction right-of-way. Modifications or improvements to these access roadsmay include grading or other minor maintenance to prevent rutting during use, placement of additionalgravel or crushed stone on the existing surface, enlargement to accommodate the pipeline equipment,such as stringing trucks, and/or installation of board or timber mats that will be removed upon completionof construction. Table 1A-3 provides access road locations, length, existing surface type, and existing

land use [Note: Not included in this draft].

Pipe / Contractor yards and Staging Areas1.4.1.4

Pipe / contractor yards and staging areas are needed for various uses, such as stockpiling pipe, fabricatingconcrete weights and piping assemblies, staging construction operations, storing construction materials,

parking equipment, and for temporary construction offices. Three pipe / contractor yards and four stagingareas have been identified for use during construction of the Project. In general, the pipe / contractoryards and staging areas will require minimal improvements, primarily in the form of a graded gravel baseto stabilize the ground surface and allow for motor vehicle traffic, delivery and storage of pipe andassociated equipment and materials, and placement of storage trailers and on-site office trailers. Land forPipe / Contractor Yard 2 and 3 will be owned by Millennium. Land for the remaining pipe / contractoryard and staging areas will be leased by Millennium during construction. The pipe / contractor yards andstaging areas are included in Table 1.4-4 and a map of the locations is included in Appendix 1C.

Operational Easement1.4.1.5

Following construction of the pipeline, in areas where Millennium can co-locate the Huguenot Loop withits existing right-of-way, Millennium will retain an additional 25 feet of the construction right-of-way as a

permanent easement to allow for inspection and maintenance of the pipeline during operation. In areaswhere co-location is not possible Millennium will retain 50 feet of the construction right-of-way as a

permanent easement to allow for inspection and maintenance of the pipeline during operation.

1.4.2 Aboveground Facilities

Table 1.4-2 above summarizes land requirements for construction and operation of the proposed new andmodified aboveground facilities. See Resource Report 8 for additional information on property size and

new land requirements for the new and modified aboveground facilities [Note: Not included in this draft].Millennium already owns the land required for construction and operation of the new compressor buildingat the Hancock CS. Millennium owns the property where the new Highland CS will be located.Millennium will obtain an agreement or license with the landowner for use of the land required forconstruction and operation of the modifications at the Westtown M&R and Ramapo M&R. Millenniumis in the process of obtaining a permanent easement from Orange County for the new land required at theRamapo M&R.

1.5 CONSTRUCTION SCHEDULE AND COMPLIANCE PROCEDURES

1.5.1 Construction Schedule

Millennium plans to commence construction in September 2017, pending receipt of all applicable permitsand clearances. The duration of construction for the proposed new Highland CS is estimated to be 8 to 10months. The duration of construction for proposed modifications at the existing Hancock CS andRamapo M&R is estimated to be 4 to 8 months. The Project is scheduled to be in service by September2018.



27/184


Millennium will install the pipeline using one construction spread for the pipeline, and smaller workcrews for the HDDs, meter stations, and launcher and receiver. The order in which each facility will beconstructed may vary, depending upon the capabilities of each contractor, weather, available workforceand optimized construction logistics. Separate construction crews will be used for each of the proposedaboveground facilities with the exception of the tie-in valves and launcher/receiver. The estimated peakProject construction work force is expected to be approximately 220 workers. Millennium anticipatesapproximately 60 percent of the construction workforce for the pipeline and approximately 40 percent ofthe construction workforce for the aboveground stations will be local hires.

1.5.2 Compliance Assurance Measures

To ensure that construction of the Project facilities will comply with mitigation measures identified inMillennium’s applications and supporting documentation, the FERC’s environmental conditions, and therequirements of other applicable permitting agencies, Millennium will include, whenever appropriate,

environmental requirements in its construction drawings and / or specifications. To solicit accurate bidsfor pipeline construction, Millennium will provide these specifications and advance versions of theConstruction Drawing Packages to qualified prospective pipeline contractors. Contractors selected to

perform work on the Project will receive copies of specifications and a Construction Drawing Packagecontaining pipeline and aboveground facility drawings designated as being approved for construction.

For those mitigation measures that address pre-construction surveys and clearances, Millennium willinclude pertinent correspondence documenting compliance with these mitigation measures in theConstruction Drawing Package. For those mitigation measures that address permit conditions fromapplicable regulatory agencies, Millennium will include copies of permits and related drawings in theConstruction Drawing Package. For those mitigation measures that, in part, address post-constructionrequirements, Millennium will include instructions and documentation that will be provided to operating

personnel following the completion of construction. These maintenance instructions will include copiesof pertinent permits with particular reference to long-term permit conditions and reporting requirements.

Millennium will require the selected contractors to install the proposed facilities according toMillennium’s standard specifications, the Construction Drawing Package, and the terms of a negotiatedcontract. To support the application of proper field construction methods, Millennium has generallyincorporated the FERC’s Upland Erosion Control, Revegetation and Maintenance Plan (FERC Plan) andFERC’s Waterbody and Wetland Construction and Mitigation Procedures (FERC Procedures) into theProject’s Environmental Construction Standards (ECS) to address the site-specific conditions in the

Project area (see Appendix 1B) [Note: Not included in this draft]. Any deviations from, or additions to,the FERC Procedures have been identified in Section 1.6.2 for FERC approval prior to implementation.

Appendix 1B includes the following plans that Millennium will implement during construction of theProject:

• Project ECS (including Spill Prevention and Response Procedures that provide procedures forhazardous materials transportation, handling, storage, spill prevention, and spill response);



28/184


• Horizontal Directional Drill Contingency Plan (HDD Plan) [Note: Not included in this draft] that provides procedures to be followed during HDD operations to minimize the potential for releaseof drilling fluids, containment and cleanup of inadvertent releases of drilling fluids should theyoccur, and steps that will be followed if the HDD cannot be completed as planned;

• Bedrock Blasting Plan [Note: Not included in this draft]; and

• Environmental Complaint Resolution Procedures so that landowners and stakeholders may reportenvironmental complaints or concerns, and a process for resolving these concerns [Note: Notincluded in this draft].

In addition, Millennium will implement its Procedures Guiding the Discovery of Unanticipated CulturalResources and Human Remains in the event that unanticipated cultural resources or human remains areencountered during construction. These procedures are included in Resource Report 4, Appendix 4B ofthis Environmental Report [Note: Not included in this draft].

Millennium will conduct environmental training sessions for all Millennium construction managementand contractor personnel prior to and during the pipeline installation and aboveground facilityconstruction. While this training will focus on implementation of best management practices contained inthe plans in Appendix 1B, it will also include instructions on construction work area limits, permitrequirements, and other mitigation measures, as appropriate.

Millennium will employ a minimum of one full-time Environmental Inspector for the duration of Projectconstruction. The Environmental Inspector(s) will have duties consistent with those contained inParagraph II.B. (Responsibilities of Environmental Inspectors) of the FERC Plan, including ensuringcompliance with environmental conditions attached to any Certificate issued by the FERC for the Project,

Project environmental designs and specifications, and environmental conditions attached to other permitsor authorizations. Millennium will provide training for its Environmental Inspector(s) regarding properfield implementation of the FERC Plan and FERC Procedures, hazardous materials management, andother mitigation measures included in Appendix 1B.

For purposes of quality assurance and compliance with mitigation measures, other applicable regulatoryrequirements, and Millennium specifications, Millennium also will be represented on the constructionsites by a Chief Construction Inspector, and one or more Craft Inspectors. Millennium’s Engineering andProject Management personnel will be responsible for designing and constructing the facilities incompliance with regulatory and non-regulatory requirements and agreements. The Construction SiteManager will address any issues of noncompliance with mitigation measures or other regulatoryrequirements. If technical or management assistance is required, the Chief Inspector will requestassistance from the appropriate Millennium personnel. Millennium’s Operator, Columbia PipelineGroup, will be responsible for long-term Project operation, maintenance and regulatory compliance.



29/184


1.6 CONSTRUCTION PROCEDURES


Construction of the Project will follow industry-accepted practices and procedures, as further described below. Generally, construction of the Project pipeline will follow a set of sequential operations as shownin Figure 1.6-1, Typical Pipeline Construction Sequence. In this typical pipeline construction scenario,the construction spread proceeds along the pipeline right-of-way in one continuous operation. The entire

process will be coordinated in such a manner as to minimize the total time a tract of land is disturbed andtherefore exposed to erosion and temporarily precluded from normal use.



30/184


FIGURE 1.6-1 Typical Pipeline Construction Sequence



31/184


To minimize the impacts of construction disturbance, Millennium will implement the Project ECS. Thefollowing sections provide descriptions of activities along a typical construction spread, as well as otherspecialized construction methods that will be used to install the pipeline at waterbody and road crossings,and in wetland, residential, and agricultural areas.

Typical Upland Pipeline Construction Procedures1.6.1.1

The Project will be constructed in compliance with applicable federal regulations and guidelines, and thespecific requirements of the necessary permits (see Section 1.10, Permits and Approvals). Key federalrequirements and guidelines include:

• 18 CFR Part 380 – FERC’s Regulations Implementing the National Environmental Policy Act(including § 380.15 - Siting and Maintenance Requirements);

• 49 CFR Part 192 – Transportation of Natural Gas and Other Gas by Pipeline: Minimum FederalSafety Standards; and

• The FERC Plan and FERC Procedures.

The following sections provide descriptions of activities along a typical construction spread, as well asother specialized construction methods that will be used to install the pipeline at waterbody, road, and inwetland, residential, and agricultural areas.

Surveying

The initial step in preparing the right-of-way for construction is the civil survey. Affected landowners

have been contacted and requested to permit Millennium agents to enter property prior to surveying andstaking of the centerline and workspaces for construction.

The civil survey crew will stake the outside limits of the construction right-of-way, the centerline locationof the pipeline, drainage centerlines and elevations, highway crossings, and any ATWS, such as in laydown areas or at stream crossings. The “811” underground utility location system will be contacted toallow state and local utility operators to verify and mark all underground utilities (e.g., cables, conduits,and pipelines) located within the construction work areas. To further minimize the potential for damageto buried facilities, field instrumentation, or test pits excavated using “soft digging” techniques (such asexcavation by hand), will be used to locate utilities.

Clearing and Grading

Following surveying, the right-of-way will be cleared. Large obstacles such as trees, rocks, brush, andlogs will be removed. Trees will be felled by hand or mechanical means. When construction begins,timber and other vegetation debris may be chipped for use as erosion-control mulch, burned, sold, orotherwise disposed of in accordance with applicable state and local regulations, and landowner easement



32/184


agreements. Fences will be cut and braced along the right-of-way, and temporary gates will be installedto control livestock and limit public access.

The right-of-way will then be graded where necessary to create a reasonably level working surface toallow safe passage of construction equipment and materials, and for operation of pipe fabrication andinstallation equipment. During the grading operation, temporary flume pipes will be installed asnecessary to maintain surface drainage. In upland areas, temporary erosion control measures such as siltfencing and interceptor dikes will be installed during topsoil and subsoil removal. Within 100 feet ofwetlands and waterbodies as well as within the 100-year floodplain, temporary erosion control measuressuch as silt fencing and interceptor dikes will be installed prior to conducting any grading activities.Conserved topsoil will typically be stockpiled along one side of the right-of-way, allowing the other sideto be used for access, material transport, and pipe assembly. Where the temporary workspace overlapswith the permanent easement associated with the existing Millennium mainline pipeline, topsoil andsubsoil will typically be stockpiled within the portion of the workspace located within the existing

permanent easement.

Trenching

To bury the pipeline underground, it will be necessary to excavate a trench. The trench will be excavatedwith a rotary trenching machine, a track-mounted backhoe, or similar equipment. Generally, the trench

bottom will be excavated at least 12 inches wider than the diameter of the pipe. The sides of the trenchwill be sloped with the top of the conventional lay trench up to 20 feet across, or more, depending uponthe stability of the native soils and the depth of cover. The trench will be excavated to a sufficient depthto allow a minimum of 3 feet of soil cover between the top of the pipe and the final land surface after

backfilling. Additional cover will be provided at crossings of wetlands and waterbodies, agriculturallands and roads. Excavated soil will typically be stockpiled along the trench (the “spoil” side) and awayfrom the construction traffic and pipe assembly area (the “working” side). Where the pipeline is adjacentto an existing pipeline, the spoil will be placed on the same side of the trench as the existing pipeline. Noworking equipment will operate over the active pipeline unless the pipeline is adequately protected inaccordance with the foreign pipeline company’s standards. When trenching near foreign buried utilities,soft digging methods (hand excavation or an excavator bucket without teeth or side cutters) will be usedto fully excavate any foreign line (see Section 1.6.1.5). Millennium will execute a one call prior toconstruction in a foreign utility location. If a foreign line is accidentally damaged during construction, aMillennium representative will shut down activities and evacuate the area. Millennium will make alleffort to have a foreign line representative onsite during excavation to facilitate quicker shut down in the

event of accidental damage. Millennium will implement the Project ECS (Appendix 1B) duringconstruction in the vicinity of overhead electric lines.

• Trench Depth

o Trench depths are dependent on the size of pipe and the minimum cover requirements. Itis currently anticipated that trench depths in upland areas, where 36 inches of cover is to

be maintained, will be approximately six to eight feet in depth.



33/184


34/184


filter bag. Filter bags will not be used within 100 feet of wetlands or waterbodies. The dewateringstructure will be removed as soon as possible after completion of the dewatering activities. Trench plugswill be used where necessary to separate the upland trench from adjacent wetlands or waterbodies to

prevent the inadvertent draining of the wetland or diversion of water from the waterbody into the pipetrench.

Stringing

Steel pipe will be procured in nominal 40-foot, 60-foot, and/or 80-foot lengths, or “joints,” protected withan epoxy coating applied at the factory or at a coating yard (the beveled ends will be left uncoated forwelding) and shipped to strategically located materials storage areas, or “pipeyards.” The individual

joints will be transported to the right-of-way by truck and placed along the excavated trench in a single,continuous line, easily accessible to the construction personnel on the working side of the trench,typically opposite the spoil side. This will allow the subsequent lineup and welding operations to proceed

efficiently. At stream crossings, the amount of pipe required to span the stream will be stockpiled inATWS on one or both banks of the stream.

Pipe Bending

The pipe will be delivered to the job site in straight joints. While some induction bends may be used,some bending of pipe will be required to allow the pipeline to follow natural grade changes and directionchanges of the right-of-way. Prior to welding, selected joints will be bent in the field by track-mountedhydraulic bending machines.

Pipe Assembly and Welding

Following stringing and bending, the joints of pipe will be placed on temporary supports, adjacent to thetrench. The pipe joints will be carefully aligned with clamps and welded together using multiple passesfor a full penetration weld. Only qualified welders will be allowed to perform the welding. Welders andwelding procedures will be qualified according to applicable American Society for Mechanical Engineers,API, and 49 CFR Part 192 Standards.

Non-Destructive Examination and Weld Repair

To ensure that the assembled pipe will meet or exceed the design strength requirements, 100 percent ofthe pipeline girth welds will be visually inspected and tested for integrity using non-destructiveexamination methods such as radiography (X-ray) or ultrasound, in accordance with API standards.Welds displaying unacceptable slag inclusions, void spaces, or other defects will be repaired or cut out,re-welded, and re-inspected.



35/184


Coating Field Welds, Inspection, and Repair

Following welding, the previously uncoated ends of the pipe at the joints will be cleaned and epoxycoated in accordance with Millennium’s specifications. The coating on the completed pipe section will beinspected and any damaged areas will be repaired and re-inspected.

Lowering-In

The completed section of pipe will be lifted off the temporary supports and lowered into the trench byside-boom tractors or equivalent equipment. Prior to lowering the pipe, the trench will be inspected toensure that it is free of rocks and other debris that could damage the pipe or the coating, and that thetrench and pipe configurations are compatible, and then the pipe will be lowered-in. In rocky areas, if the

bottom is not smooth, a layer of soil or sand may be placed on the bottom of the trench to protect the pipeand coating from damage. Concrete coating and/or set-on or saddle bag type weights will be used as

required to maintain negative buoyancy in areas of saturated soils.

Padding and Backfilling

After the pipe is lowered into the trench, the trench will be backfilled. Previously excavated materialswill be pushed back into the trench using bladed equipment or backhoes. Where the previously excavatedmaterial contains large rocks or other materials that could damage the pipe or coating, the subsoil will besifted to remove any rock greater than one inch from the padding material, or clean fill and/or protectivecoating (rock shield) will be placed around the pipe prior to backfilling. Segregated topsoil, whereapplicable, will be placed after backfilling the trench with subsoil. Following backfilling in agriculturalland, grassland, and open land, or in specified areas, a small crown may be left in certain areas if

requested by a landowner to account for any future soil settling that might occur. Excess soil will only bedistributed in upland areas evenly on the right-of-way, while maintaining existing contours.

A caliper pig run will be completed after backfill to ensure there are no dents or damage to the pipe as aresult of the construction and backfill process.

Hydrostatic Test and Final Tie-In

Following backfilling of the trench, the pipeline will be hydrostatically tested in a manner that meets orexceeds the requirements of 49 CFR Part 192 to ensure that it is capable of safely operating at the design

pressure. Millennium proposes to use approximately 2.1 million gallons of water for hydrostatic testingon the Huguenot Loop. Millennium is currently identifying potential source water for hydrostatic testingactivities. Water will be obtained and discharged within the Lower Hudson Watershed, no inter-basintransfer of water is anticipated. A table identifying the total amount of water that would be used for theProject, potential source water, and milepost locations is included in Resource Report 2 [Note: Notincluded in this draft].



36/184


The pipeline will be capped and filled with water and the current plan is to test it in multiple test sectionsdue to elevation changes. The water in the pipe will be pressurized and held for a minimum of eighthours in accordance with the Pipeline and Hazardous Materials Safety Administration requirementsidentified in 49 CFR Part 192. Any loss of pressure that cannot be attributed to other factors, such astemperature changes, will be investigated. Any leaks detected will be repaired and the segment will beretested.

The test water will be discharged through an energy-dissipating device in compliance with the FERCProcedures and any state-specific requirements included in the applicable state discharge permits. Oncethe pipe has been successfully tested and dried to the specified dew point, the test cap and manifold will

be removed.

Millennium will implement applicable requirements of the FERC Procedures regarding hydrostatictesting, as well as any specifications listed in individual state permits. Unless expressly permitted or

approved, there will be no direct discharge into state-designated exceptional value waters or scenic rivers.

Cleanup and Restoration

Post-construction restoration activities will be undertaken in accordance with the applicable measures inthe FERC Plan and FERC Procedures, other permit or agency requirements, and requirements in thelandowner easement agreements. After a segment of pipe has been installed and backfilled, the right-of-way, ATWS, and other disturbed areas will be finish-graded, and the construction debris will be disposedof properly. The surface of the right-of-way disturbed by construction activities will be graded to matchoriginal contours and to be compatible with surrounding drainage patterns, except at those locationswhere permanent changes in drainage will be required to prevent erosion, scour, and possible exposure ofthe pipeline. Segregated topsoil will be returned to its original horizon, unless otherwise requested by thelandowner. Temporary and permanent erosion and sediment control measures, including silt fencing,diversion terraces, and vegetation, will be installed at that time. Temporary erosion and sedimentcontrols, including silt fence and other non-biodegradable measures, will be removed once disturbed areashave been stabilized. Private and public property, such as fences, gates, driveways, and roads, whichhave been disturbed by the pipeline construction, will be restored to original or better condition.

Wetland Construction Procedures1.6.1.2

Millennium has considered minimizing potential impacts to wetlands during selection of its proposed

route and will avoid or minimize wetland disturbance to the extent practicable. Where wetlands cannot be avoided, crossings of jurisdictional wetlands will be done in accordance with applicable permits andapprovals, and the FERC Procedures, including any deviations requested by Millennium and approved bythe FERC.

Operation of construction equipment in wetlands will be limited to that needed to clear the right-of-way,excavate the trench, fabricate and install the pipe, backfill the trench, and restore the right-of-way.Millennium will segregate the topsoil over the trench up to 12 inches in depth in wetlands where



37/184


hydrologic conditions permit this practice. Segregated topsoil will be piled a minimum of two feet fromsubsoil and replaced in the trench following subsoil backfilling. In accordance with the FERCProcedures, with the exception of pumps required for dewatering, fuel and/or equipment will not bestored within 100 feet of wetlands or other waterbodies unless otherwise approved by the FERC.Restoration and monitoring of wetland crossings will be conducted in accordance with the FERCProcedures to ensure successful wetland revegetation.

Unsaturated Wetland Crossings

In crossing unsaturated wetlands (wetlands without standing water or saturated soils), construction will besimilar to the typical upland construction described above, with additional measures to protect wetlandresources. If normal construction equipment begins to rut or would result in mixing of wetland topsoiland subsoil, low ground pressure equipment will be used, or temporary board or timber equipment matswill be installed to allow passage of equipment with minimal disturbance of the surface and vegetation.

Trees will be cut to grade, but stumps will only be removed from the trench line and from the workingside where necessary for safety. Topsoil over the pipe trench will be segregated from subsoils and piled aminimum of two feet apart. A vegetation buffer zone may be left between the wetland and the uplandconstruction areas, except for the pipe trench and travel lane and as site-specific conditions warrant.Erosion control measures such as silt fences, interceptor dikes, and straw/hay bale structures will beinstalled and maintained to minimize sedimentation into off-right-of-way areas. Trench plugs will beinstalled where necessary to prevent the unintentional draining of water from the wetland. Uponcompletion of construction, the right-of-way will be restored and a 10-foot-wide strip centered on the

pipeline will be maintained in an herbaceous state.

Saturated Wetland Crossings

For saturated wetlands, including those with standing water at the time of construction, topsoilsegregation may not be practical. Equipment mats or timber mats will be used to facilitate equipmentmovement through and work within the wetland. Otherwise, construction will be similar to that describedabove for unsaturated wetlands.

Waterbody Construction Procedures1.6.1.3

Millennium will follow the FERC Procedures to limit water quality and aquatic resource impacts duringand following construction. Construction activities will be scheduled so that the pipeline trench isexcavated as close to pipe laying activities as reasonably possible. In accordance with the FERCProcedures and where the pipeline will not be installed using HDD, the duration of construction across

perennial waterbodies will be limited to 48 hours (24 hours to cross the waterbody and 24 hours forrestoration) across minor waterbodies (10 feet wide or less) and intermediate waterbodies (between 10and 100 feet wide). Banks will be returned to as near to pre-construction conditions as possible within 24hours of completion of each open-cut crossing. Any deviations in timing that would result in extendedcrossing durations will be identified in advance by Millennium and notification made to FERC with site-specific justification.

Construction methods at waterbody crossings will vary with the characteristics of the waterbodyencountered, and will be performed consistent with applicable permits and authorizations. Pipe will beinstalled to provide a minimum of five feet of cover from the waterbody bottom to the top of the pipeline.The bottom of the pipeline trench will be excavated to a width of at least 12 inches greater than thediameter of the pipe or to a greater width to allow proper backfill beneath and along the sides of the

pipeline.

Trench spoil will be placed on the bank above the high water mark for use as backfill. Excavated spoilthat is stockpiled in the construction right-of-way will be at least 10 feet from the stream bank or inapproved ATWS, and will be surrounded by sediment control devices to prevent sediment from returningto the waterbody. Where the pipeline is prefabricated for installation across the waterbody, the pipelinesegment will be long enough to extend for a minimum of 10 feet past the high banks on each side of thewaterbody before raising in elevation to the normal trench level. All adjacent pipelines will be protected

as necessary.

Normal backfill cover requirements will be met and backfill compacted so that it will be equal to or abovethat of the adjacent undisturbed areas. Trench plugs of sandbags or similar material may also be used tokeep backfill from sloughing in toward the center of the waterbody. All waterbody banks will be restoredto as close to the original grade as reasonably possible, while preventing long-term erosion. All erosioncontrol materials or other materials used for the crossing will be removed from the waterbody, andexcavated material not required for backfill will be removed and disposed of at an upland site.

The proposed crossing method for each waterbody is provided in Table 2A-1 in Resource Report 2 [Note: Not included in this draft]. Millennium will use the dry waterbody crossing method for waterbodies withno discernible flow at the time of crossing and the dry-ditch (i.e., dam and pump or flume) crossingmethods for minor and intermittent waterbodies where there is discernable flow within the waterbody atthe time of crossing. The dry-ditch waterbody crossing method used at each specific crossing (dam and

pump or flume) will be dependent upon the conditions encountered at the time of construction. Onemajor waterbody crossing (i.e., those greater than 100 feet wide) is proposed, the Neversink River (MP0.3). Millennium is currently evaluating the use of a trenchless crossing technique for the NeversinkRiver. A site-specific crossing plan for this waterbody is included in Appendix 1C (Site-specific HDD

plans) [Note: Not included in this draft].

Dry Waterbody Crossing Method

A dry waterbody crossing will use methods similar to conventional upland open-cut trenching. The drywaterbody construction method will involve excavation of the pipeline trench across the dry stream bed,installation of a prefabricated segment of pipe, and backfilling of the trench with native material.Depending upon the width of the crossing and the reach of the excavating equipment, excavation and

backfilling of the trench will generally be accomplished using backhoes or other excavation equipmentoperating from one or both banks of the dry streambed. If necessary for reach, the equipment mayoperate within the dry streambed. Equipment in the dry streambed will be limited to that needed to

complete the crossing. All other construction equipment will cross the dry streambed using equipment bridges, unless otherwise allowed by the FERC Procedures for minor waterbody crossings.

The “dry waterbody” crossing method shall only be used in streams that have no discernable flow duringthe time of construction, provided that a contingency plan is developed that prescribes measures to betaken in case of a storm event during trenching. Measures shall include, but are not limited to: monitoringweather conditions closely during work within the stream channel; moving equipment and materialsoutside of the stream channel if a storm event is predicted; installing a temporary waterbody crossingmethod prior to the predicted storm event; and temporarily stabilizing the stream channel.

Dam and Pump Crossing Method

The dam and pump method involves installation of temporary dams upstream and downstream of thewaterbody crossing. The temporary dams typically will be constructed using sandbags and plastic

sheeting. Following dam installation, appropriately sized pumps will be used to dewater and transport thestream flow around the construction work area and trench. Intake screens will be installed at the pumpinlets to prevent entrainment of aquatic life, and energy dissipating devices will be installed at the pumpdischarge point to minimize erosion and stream bed scour. Trench excavation and pipeline installationwill then commence through the dewatered portion of the waterbody channel. Following completion of

pipeline installation, backfill of the trench, and restoration of stream banks, the temporary dams will beremoved, and flow through the construction work area will be restored. This method is generally onlyappropriate for those waterbody crossings where pumps can adequately transfer the stream flow volumearound the work area and there are no concerns
