Q. Please describe MPL.15

A. MPL is a Delaware limited liability company authorized to transact business in the State 16

of Michigan. MPL is a wholly owned subsidiary of MPC, a Delaware limited liability 17

company.18

MPL is experienced in the design, construction, installation, operation and maintenance 19

of pipelines, including those utilized for the transportation of crude oil, petroleum and 20

petroleum products. MPL and its predecessor companies have been operating pipelines 21

for over 100 years. MPL currently has approximately 525 employees.22

{223529.DOC 2} 4

MPL currently owns and operates approximately 260 miles of pipeline and related 1

facilities within the State of Michigan. MPL owns and/or operates approximately 6,000 2

miles of pipeline and related facilities throughout the United States. MPC’s Detroit 3

refinery, which will be supplied crude oil by the proposed pipeline, presently supplies 4

approximately 20% of Michigan’s liquid petroleum products needs.5

Q. Please describe the authority that MPL is seeking from the Michigan Public Service 6

Commission (the “Commission”) by way of its present application.7

A. MPL seeks authority pursuant to 1929 PA 16, MCL 483.1 et seq., as amended, to design, 8

construct, install, operate and maintain approximately 29 miles of 24-inch diameter 9

pipeline for the transportation of crude oil and petroleum. This proposed pipeline would 10

begin at MPL’s Samaria, Monroe County, Michigan Station and extend approximately 11

29 miles to Huron River Junction in southern Wayne County, Michigan where it will 12

then connect with MPL’s existing 16-inch diameter pipeline which runs to MPC’s 13

Detroit refinery. Currently, a 16-inch diameter pipeline owned and operated by MPL 14

runs from the Samaria Station to MPC’s Detroit refinery. To meet additional demand for 15

the heavier, Canadian crude oil at MPC’s Detroit refinery, MPL proposes to construct a 16

new pipeline segment to replace a segment of the existing pipeline between the Samaria 17

Station and Huron River Junction to be located in southern Wayne County. Once the 18

proposed pipeline has been constructed, installed, tested, commissioned and placed in 19

operation, MPL will idle, maintain and protect the 29-mile segment of existing 16-inch 20

pipeline. 21

{223529.DOC 2} 5

MPL intends to acquire necessary easements or agreements through negotiations with the 1

property owners. However, MPL requests the Commission’s certification to use eminent 2

domain authority should it become necessary.3

Q. Please describe the history of the 16-inch pipeline which will have a portion 4

replaced by the proposed pipeline.5

A. The Commission, in Case No. U-211, by Order dated June 9, 1960, authorized Buckeye 6

Pipeline Company to construct and operate the existing 16-inch pipeline. Marathon Pipe 7

Line Company purchased the existing 16-inch pipeline from Buckeye Pipeline Company 8

in 1976 and on October 15, 1976 filed a notice with the Commission indicating its rights 9

and obligations pertaining to this pipeline. Marathon Pipe Line Company, the 10

predecessor to MPL, operated this pipeline beginning in 1976 and it is currently owned 11

and operated by MPL. 12

Q. Please explain the purpose of the proposed pipeline MPL seeks authority to 13

construct.14

A. MPC is proposing a project at its Detroit refinery, the only refinery in the State of 15

Michigan, to process increased amounts of the heavier, more viscous Canadian crude oil 16

as a step toward increasing the flexibility of crude oil supply sources. There is 17

insufficient capacity on the existing pipeline to transport this additional amount of 18

Canadian crude oil to the Detroit refinery.19

Q. Please explain why the pipeline proposed by MPL is needed.20

A. MPL’s existing pipeline is currently transporting approximately 120,000 barrels per day 21

of crude oil, of which 25,000 barrels per day is the heavier Canadian crude oil, to MPC’s 22

Detroit refinery for processing. In order to transport up to 144,000 barrels per day of 23

{223529.DOC 2} 6

crude oil, of which approximately 100,000 barrels per day will be the heavier Canadian 1

oil, the throughput capacity on the existing pipeline would need to be increased. MPL’s 2

existing pipeline can only transport approximately 90,000 barrels per day of the heavier 3

Canadian crude oil, leaving MPC’s Detroit refinery 54,000 barrels per day of crude oil 4

short of their projected needs. Pipelines are the safest and most efficient means of 5

transporting the necessary crude oil volumes to MPC’s Detroit refinery. 6

To accomplish transportation by trucking or rail vehicles of the 54,000 barrel per day 7

additional capacity to be added by the proposed pipeline would require the use of 8

approximately 270 tanker truck loads per day or 85 rail car loads per day. This 9

alternative to the proposed pipeline is not feasible because a vehicle based transportation 10

system introduces the new risk of vehicle accidents into the distribution system. In 11

addition, there are no existing loading or unloading facilities available to sufficiently 12

handle the volume of truck or rail vehicles necessary to serve as an alternative. 13

Vehicular transportation has a higher risk of accidents than do pipelines. Vehicular 14

transportation by truck and rail will increase congestion to roads and increase the amount 15

of fossil fuels utilized during transportation. The use of trucks and trains to transport 16

would also cause an increase in air emissions for the region. Pipeline transportation is 17

also less expensive than other transportation modes.18

Q. Please describe the route of the proposed pipeline that MPL seeks authority to 19

construct.20

A. The proposed pipeline route originates at MPL’s Samaria Station, located in Bedford 21

Township, Monroe County, and terminates in Flat Rock, southern Wayne County. The 22

proposed pipeline route generally follows the corridor of MPL’s existing 16-inch 23

{223529.DOC 2} 7

pipeline, which also originates at MPL’s Samaria Station and terminates at MPC’s 1

Detroit refinery, and co-locates with the existing pipeline and other pipeline, utility and 2

developed corridors for over 63% of the total proposed pipeline route. The proposed 3

pipeline route crosses Bedford, Ida, LaSalle, Raisinville, Frenchtown Charter and Ash 4

Townships in Monroe County and the City of Flat Rock and Huron Charter Township in 5

Wayne County. Although the proposed pipeline route generally follows the corridor of 6

MPL’s existing pipeline, the proposed pipeline route deviates from the co-location areas 7

to avoid residential encroachments that are near MPL’s existing pipeline, avoid or 8

minimize significant environmental impacts, or as a result of discussions with property 9

owners. The overall proposed pipeline route can be characterized as predominantly 10

agricultural, with sporadic areas of residential development. Public lands are avoided, 11

except where the proposed pipeline terminates due to the location of MPL’s existing 12

pipeline within the Oakwoods Metropark in southern Wayne County.13

Q. Please discuss Exhibit A-1 (DM-1).14

A. Exhibit A-1 (DM-1) is a map of the proposed pipeline route. This map depicts the area 15

to be crossed by the proposed pipeline.16

Q. Please explain why this route was selected for the location of the proposed pipeline.17

A. To create a more stable supply of petroleum products for Michigan motorists and other 18

customers, MPC must process an increased amount of crude oil produced fromCanadian 19

oil sands at its Detroit refinery. To transport additional supplies of Canadian crude oil, 20

which are becoming available through production in the Canadian oil sands, it was 21

determined that increased pipeline capacity was needed along the route of the existing 22

16-inch pipeline. Based upon various engineering analyses, it was determined that the 23

{223529.DOC 2} 8

most appropriate segment for this larger diameter pipeline would be the approximately 1

29 mile segment running from MPL’s Samaria Station to Huron River Junction in 2

southern Wayne County.3

Once that decision was made, MPL evaluated the existing pipeline route in an effort to 4

locate the proposed pipeline approximately parallel to the existing 16-inch pipeline 5

where practical. Following MPL’s existing pipeline and other pipeline, utility and 6

developed corridors is generally less disruptive to the environment and property owners 7

due to previous land segmenting and disturbances from the existing corridors. However, 8

in the four and one half decades since construction of the original pipeline, development 9

in the vicinity of the existing pipeline, as well as environmental considerations, created 10

situations where MPL deemed it prudent to find an alternative route for short distances 11

so as to minimize disruptions and impacts. After a thorough environmental and 12

engineering analysis, the proposed pipeline route was selected to minimize overall 13

impacts to the environment, property owners, land uses and to enhance the safety and 14

efficiency of construction and operation functions. 15

Q. Did you evaluate any alternative systems to the proposed pipeline? 16

A. Yes. There is essentially one alternative system to the proposed pipeline. That alternative 17

is to use continuous trucking or rail haul operations to transport the crude oil to the 18

refinery via the existing network of roads and railroads. To accomplish transportation by 19

trucking or rail of the 54,000 barrel per day additional capacity to be added by the 20

proposed pipeline would require the use of approximately 270 tanker truck loads per day 21

or 85 rail car loads per day. This alternative would require additional infrastructure to be 22

built, at a significant cost, at both MPL’s Samaria Station and MPC’s Detroit refinery to 23

{223529.DOC 2} 9

support trucking or rail activity. This alternative would be less reliable, more expensive, 1

and would include safety issues that must be overcome for the loading and unloading 2

activities and general transportation. In essence, this is a comparison of the possible 3

modes of transportation to deliver crude oil to MPC’s Detroit refinery, however, the 4

proposed pipeline remains the most efficient, cost effective and feasible alternative.5

Q. Please discuss Exhibits A-2 (DM-2) and A-3 (DM-3).6

A. Exhibit A-2 (DM-2) shows the general engineering specifications of the proposed 7

pipeline segment. Once the proposed pipeline segment is constructed, installed, tested, 8

commissioned and placed in operation, the resulting pipeline system will have a 9

throughput capacity of 144,000 barrels per day of the heavier crude oil slate and a 10

maximum operating pressure of 1440 psig. Exhibit A-2 (DM-2) delineates the pipeline 11

operating data, design, pipe specifications, valve and fitting specifications. Exhibit A-3 12

(DM-3) sets forth construction and installation procedures for the proposed pipeline 13

replacement segment.14

Q. Will MPL comply with applicable federal laws and other requirements governing 15

the design, construction, installation, operation and maintenance of liquid 16

petroleum pipelines?17

A. Yes. MPL will design, construct, install, maintain and operate the pipeline system in 18

accordance with the standards and requirements established by PHMSA. The project 19

will incorporate the latest in pipeline system technology and materials specifically 20

designed to provide safe, minimally-intrusive, economical and reliable transportation of 21

crude oil and petroleum. In fact, as Exhibit A-4 (DM-4) shows, MPL’s design, 22

{223529.DOC 2} 10

construction and installation specifications meet the requirements of the regulations 1

promulgated by the U.S. Department of Transportation for petroleum pipelines.2

Pipelines are operated under a variety of regulations and industry standards that address 3

all aspects of pipeline operations to protect the health and safety of the public and the 4

environment. Pipeline operators and operations are inspected by pipeline safety 5

inspectors to ensure they meet or exceed these regulatory requirements and standards. 6

In addition, the methods employed in the construction of the pipeline will incorporate 7

measures designed to protect and restore soils, groundwater, and cultural and historic 8

resources as indicated in the Environmental Impact Report prepared by MPL’s 9

environmental consultant, Sendero Environmental, LLP. Further, the proposed pipeline10

will be constructed in accordance with conditions set forth in permits obtained from 11

federal, state and local agencies.12

Q. Please identify Exhibit A-5 (DM-5).13

A. This is a letter dated January 19, 2007, sent by MPL sent to the Director of the Central 14

Region, PHMSA. This letter requests the Director to review a route map, a general 15

engineering specification summary and MPL’s pipeline construction standards 16

(MPLCON001). The Director is asked to confirm that MPL’s proposal meets or exceeds 17

applicable federal pipeline requirements. As of the date of this testimony, the Director 18

has not responded to this letter.19

Q. Please describe the operation and maintenance policies and procedures that MPL 20

follows concerning its pipelines.21

A. It is MPL’s policy to conduct its pipeline operation and maintenance activities in a 22

manner that protects the safety and health of the public, its employees and the 23

{223529.DOC 2} 11

environment. Inherent in this policy is strict compliance with the numerous applicable 1

laws and regulations governing the pipeline industry. MPL complies with the 2

requirements set forth by PHMSA. Specifically, MPL maintains compliance with Title 3

49 of the Code of Federal Regulations, Part 190: Safety Procedures, Part 194: Response 4

Plans for Onshore Pipelines, and Part 195: Transportation of Hazardous Liquids by 5

Pipeline. MPL also complies with, as applicable, regulations set forth by the U.S. Coast 6

Guard, the U.S. Environmental Protection Agency, the Michigan Department of 7

Environmental Quality, the Michigan Department of Natural Resources, Michigan 8

Occupational Safety and Health Administration, and the Michigan State Fire Marshall, 9

among others.10

While the above regulations are numerous, it is not an exhaustive list. The applicable 11

regulations establish minimum standards of compliance. It is MPL’s policy to use sound 12

engineering practice and pipeline industry best practices to develop internal operation 13

and maintenance procedures that meet or are more stringent than regulations require. 14

MPL maintains procedural manuals that provide guidance for employees during normal 15

operations and maintenance and during abnormal operations and emergencies. These 16

manuals are the basis for continual training for employees so that their response to any 17

normal or emergency situation is appropriate given MPL’s objective of protecting the 18

safety and health of its employees, the public and the environment. Additionally, MPL 19

conducts internal pipe inspections using devices called “smart pigs”. MPL also uses 20

engineered pressure control devices, which are monitored by manned computers 24 21

hours per day, seven days per week.22

{223529.DOC 2} 12

Q. Will these same operations and maintenance policies and procedures be applied to 1

the pipeline proposed in this application?2

A. Yes, they will.3

Q. Please compare the safety performance of the transportation of liquid products 4

such as petroleum by pipelines with other transportation modes.5

A. According to PHMSA’s web site (primis.phmsa.dot.gov/comm/FAQ.htm), “Frequently 6

Asked Questions” section, “Relative to the volumes of products transported, pipelines 7

are extremely safe when compared to other modes of energy transportation. Oil pipeline 8

spills amount to about 1 gallon per million barrel-miles (Association of Oil Pipe Lines). 9

One barrel, transported one mile, equals one barrel-mile, and there are 42 gallons in a 10

barrel. In household terms, this is less than one teaspoon of oil spilled per thousand 11

barrel-miles. Pipelines also generally have a better safety record (deaths, injuries, 12

fires/explosions) than other modes of oil transportation. For example, compared to the 13

pipeline record, there are 87 times more oil transport truck-related deaths, 35 times more 14

oil transport truck related fires/explosions and twice as many oil transport truck-related 15

injuries.”16

Q. Please describe the general construction techniques that will be used for this 17

proposed pipeline project.18

A. The proposed pipeline project will generally require 115 feet of construction right-of-19

way to construct and install the pipeline, with additional temporary work space required 20

adjacent to road, railroad and stream crossings and for horizontal directional drill areas. 21

This additional temporary work space is needed for temporary storage of excavated 22

{223529.DOC 2} 13

spoils and, in the case of horizontal directional drill areas, equipment set-up and pipe 1

handling areas.2

Typical pipeline construction follows an assembly line process, with sequential work 3

crews to minimize the overall construction timeline. After surveying the pipeline route 4

and delineating the right-of-way and environmental boundaries, the clearing crew is the 5

first component of the construction process. The clearing crew cuts and chips woody 6

vegetation and mows other vegetation along the route.7

Next, the grading crew contours the right-of-way to segregate topsoil in agricultural and 8

residential areas, allow the passage of heavy equipment and trucks along the route, and to 9

set environmental controls to minimize erosion.10

After these, come ditching, pipe stringing, pipe bending and pipe welding crews 11

followed by the radiography crews, who analyze and verify the quality of the pipe welds. 12

Lower-in and tie-in crews then place the welded pipeline string into the ditch, where a 13

series of padding and backfill crews cover the pipeline, after the as-built survey crew has 14

completed their surveys.15

Final grading and clean-up crews then establish the final grade of the right-of-way and 16

return topsoil, repair drain tile as required, reseed where appropriate and otherwise 17

restore the property as best as is practical. 18

Q. What width of easement will MPL generally seek to acquire with regard to this 19

proposed pipeline?20

A. MPL will generally seek to acquire a permanent easement having a width of 50 feet, 21

which remains clear of tall vegetation and other encroachments, as are typical of crude 22

oil and petroleum pipelines. In addition, MPL will generally seek a setback of 25 feet on 23

{223529.DOC 2} 14

either side of the permanent easement to restrict the construction of permanent structures. 1

Temporary work space, generally with a width of 15 feet, is required during construction 2

for storing topsoil and excavated spoil material. Equipment and pipe handling for the 3

horizontal directional drill sites will require larger, temporary work space areas. The 4

proposed pipeline will be offset from the existing pipeline systems 25 feet to allow safe 5

separation for pipeline maintenance activities. 6

Q. In addition to areas to be obtained for installation of the pipeline, will MPL need to 7

use lands along the pipeline route for other purposes?8

A. During construction and installation of the proposed pipeline, temporarywork space will 9

be required for storage of excavated spoil materials, pipe, contractor office and 10

equipment laydown areas and access roads to the construction right-of-way.11

Q. Please address the timing of the proposed pipeline project.12

A. MPL is seeking approval from the Commission during or before the end of 2007 to allow 13

final route survey and data collection necessary to file and obtain permits from the 14

Michigan Department of Environmental Quality and other agencies by the end of 2008. 15

MPL estimates construction on the proposed pipeline to commence in the summer of 16

2009, with the proposed pipeline being commissioned and operational in 2010.17

Q. Please identify your Exhibit A-6 (DM-6).18

A. Exhibit A-6 (DM-6) is a cost estimate for the construction of the proposed pipeline 19

segment. The estimated amount is approximately $85 million. Based on these numbers, 20

we anticipate that the project will result in temporary job creation and economic benefits 21

in area communities. MPL also estimates that, based on the anticipated cost of the 22

proposed pipeline, it will pay approximately $1.7 million annually in property taxes. 23

{223529.DOC 2} 15

These annual property tax payments will be allocated among the governmental units, 1

based on pipeline mileage, through which the pipeline passes.2

Q. Are there other utilities providing the same or similar service which are located in 3

the vicinity of the proposed pipeline?4

A. There are no other utilities providing pipeline service to MPC’s Detroit refinery. 5

Utilities rendering a similar service in the general area of the proposed pipeline include 6

Buckeye Pipeline Company, Sunoco Logistics Partners, LP, Maumee Pipeline System 7

and Enbridge’s Lakehead System.8

Q. Will MPL accept the requirements imposed by 1929 PA 16 for crude oil and 9

petroleum pipelines?10

A. Yes, it will.11

Q. Does this conclude your testimony?12

A. Yes, it does.13

document. Right-of-way will be provided on the OWNER’s construction drawings or in the Scope of Work.


Case No. U-15251 March 21, 2007


A list of right-of-way restrictions, which defines the agreements between the OWNER and landowner, will be furnished to the CONTRACTOR prior to commencement of construction, if any exist. The CONTRACTOR shall comply with these right-of-way restrictions. It is to be understood that where necessary, due to right-of-way agreements and/or physical barriers, the location of the proposed pipeline and clearing requirements may vary. The CONTRACTOR shall be required to confine their operations to the width as shown on the right-of-way restrictions. Any damage caused beyond this width shall be repaired at the CONTRACTOR’s expense.

Arrangements for additional construction space used by the CONTRACTOR shall be made by the

CONTRACTOR at the CONTRACTOR’s own expense. Any such agreements entered into by the CONTRACTOR shall be in writing, and the CONTRACTOR shall furnish one copy of all such agreements to the OWNER INSPECTOR prior to entering property.

The right of ingress and egress to the right-of-way, furnished by the OWNER shall be limited to

points where such right-of-way intersects public roads (except limited access highways), unless other access is provided by the OWNER. Arrangements for other access used by the CONTRACTOR shall be made by the CONTRACTOR, at the CONTRACTOR’s own expense. Any such agreements entered into by the CONTRACTOR shall be in writing, and the CONTRACTOR shall furnish one copy of all such agreements to the OWNER INSPECTOR prior to entering property.

The CONTRACTOR shall not allow its employees to hunt, fish, litter, or have firearms on the right-

of-way, work areas, or storage areas. 2.3 Surveying The OWNER will set surveyor’s stakes to establish the alignment of the pipeline and, unless

otherwise prescribed in the Scope of Work, these stakes will mark the center of the pipeline ditch. The CONTRACTOR shall offset these stakes for the proposed ditch. The stakes will be provided at such regularity that the continuity of the line may be maintained throughout.

The OWNER reserves the right to make changes in the pipeline alignment, and the CONTRACTOR

shall construct the line in accordance with such revised alignment. After the proposed location of the line has been located and staked by the OWNER, the

CONTRACTOR shall be held responsible for the preservation of all stakes and marks, and if any of the stakes are carelessly or willfully destroyed or disturbed by the CONTRACTOR, the cost of replacing them shall be borne by the CONTRACTOR.

All surveying shall be performed in accordance with the OWNER’s Standard MPLCON006 Onshore Surveys.

2.4 Substructures The CONTRACTOR shall be responsible for locating all existing pipelines and substructures, and

take precautions to avoid damage to drain lines, pipelines, telephone lines or cable, or other properties of the OWNER or others, crossing or adjacent to the pipeline. The CONTRACTOR shall be responsible for repair of all damage. The OWNER will make available on the plans and drawings all information in its possession concerning substructures, but will not guarantee the accuracy or completeness of such information. The CONTRACTOR shall make all necessary arrangements for locating, cutting, replacing, or repairing all substructures with their owners.

2.5 Fence Gaps and Repairs Before proceeding with construction operations, the CONTRACTOR, having first ascertained from

the OWNER that permission has been secured from the property owner, shall furnish suitable materials for and shall install temporary gaps in all fences crossed by the rights-of-way, except woven


Case No. U-15251 March 21, 2007


wire fences of the cyclone type, or other ornamental types, in which splices or repairs would detract from strength or appearance.

If woven wire fences are encountered, they must not be cut unless consent of the property owner and

tenant is first obtained, and adequate arrangements made for bracing and rebuilding. Before cutting ordinary fence wires, the CONTRACTOR shall build sturdy H-type braces on each

side of the gap and securely fasten the fence wires to them to prevent slack occurring in the fence. The CONTRACTOR shall be responsible for damages caused by slack in wire resulting from inadequate bracing or inadequate fastening of wires.

The CONTRACTOR shall be responsible for keeping gates closed at all times during performance of

work. The CONTRACTOR shall prevent livestock from entering or leaving properties, and shall furnish watchmen, if necessary, to enforce compliance with this instruction. Gaps shall be kept securely closed, except during passage of men and equipment, or when attended. Upon request of the OWNER, the CONTRACTOR shall provide a watchman during working hours at certain gaps to prevent the passage of livestock. The CONTRACTOR shall be responsible for all damage resulting from its failure to close gaps or gates and properly maintain such passages.

The CONTRACTOR shall be responsible for all materials and the installation and removal of temporary fencing, if necessary, to isolate livestock from the construction site, per landowner and/or livestock owner agreement. Areas shall be identified by the OWNER, and will be noted on the alignment sheets (or construction line list).

After completion of other work, the CONTRACTOR shall permanently repair or replace all fences in

which gaps have been cut and shall install permanent gates where so specified in the Scope of Work. Materials used for repairs shall match the original fence as nearly as practicable in gauge, mesh, style, and appearance, and shall equal or exceed the original in size and strength. All wood used shall be treated. The OWNER shall furnish all permanent gates specified in the Scope of Work but the CONTRACTOR shall furnish all other materials required for installing gaps and repairing fences as shown on attached Drawing STDM033.

2.6 Clearing and Grading The CONTRACTOR shall do such clearing and grading on the Construction Right-of-Way as is

necessary to properly perform the work and to provide access to the pipeline during the work. The CONTRACTOR may have to grade off sharp points or hollows in order to allow the pipe to bend and lay within the degree of curvature as set forth in these Specifications, and may have to drill, blast, and excavate rock in order to build an adequate work way along the pipeline route. Grading outside of the construction right-of-way is prohibited, except as hereinafter specified. Right-of-way cuts in hillsides shall be sloped as required by the OWNER REPRESENTATIVE, unless the OWNER or landowner requires that cuts shall be backfilled.

The CONTRACTOR shall clear and grub the entire width of the permanent right-of-way for the entire

continuous length of the pipeline route contracted. This also includes “vertical side-trim” of any canopy that might overhang the permanent right-of-way. "Clearing" means the removal and proper disposition of all brush and undergrowth as directed by the OWNER REPRESENTATIVE. "Grubbing" means the removal and proper disposition of certain stumps and roots as is set further herein.

Outside of the permanent right-of-way, only that amount of right-of-way necessary for actual

installation of the pipeline shall be used, and work shall be performed in such manner as to minimize damage to the greatest degree. The CONTRACTOR shall be required to pile, burn, shred, or haul away all timber, grubbed stumps, brush, undergrowth, and roots cut or removed from the right-of-way to the satisfaction of the OWNER, landowner, tenant, and governmental agencies having jurisdiction in the areas concerned.


Case No. U-15251 March 21, 2007


The CONTRACTOR may use timber cut on the right-of-way in its construction work, if permitted by

agreement with the landowners. The CONTRACTOR shall not cut timber located off the right-of-way without written permission from the landowner and tenant or lessee. At the option of the landowner, the landowner or the tenant may remove timber at their own expense. All stumps shall be grubbed within the permanent right-of-way easement, unless prohibited by permit conditions such as in wetlands. The stumps outside of the permanent easement as part of the construction easement, may be grubbed or cut, but must not project more than 4" above the top of the ground. Holes from grubbing operations shall be backfilled and compacted by the CONTRACTOR.

In the event debris disposal is by burning, the CONTRACTOR shall have all fires attended at all

times, and shall extinguish all embers before leaving the site of the fires, and shall be responsible for any damage done by fire originating along the OWNER’s right-of-way caused by the CONTRACTOR personnel, or the CONTRACTOR’s equipment. All debris disposal by burning shall be subject to all rules of federal, state, or municipal authority. Where burning permits are required, such permits shall be obtained by the CONTRACTOR. The CONTRACTOR shall furnish one copy of the permits to the OWNER INSPECTOR, prior to burning.

The CONTRACTOR shall make every effort to preserve any property corners, or monuments,

encountered along the right-of-way. Any property corners, monuments, or markers destroyed by the CONTRACTOR shall be replaced to the satisfaction of the OWNER at the CONTRACTOR’s expense.

The CONTRACTOR shall exercise particular care to avoid damming, clogging with debris, changing

the course of, or interfering with the downstream or upstream use of any stream or watercourse crossing.

All grading shall be finished to maintain the original drainage or water flow conditions, as nearly as

practicable, and shall conform to regulations of the federal, state, county or other local authorities having legal jurisdiction. The CONTRACTOR shall not, in any case, grade or level the pipeline right-of-way over cultivated land, unless it is absolutely necessary, which shall be determined at the discretion of the OWNER REPRESENTATIVE. Gaps shall be left in the rows of spoil at intervals designated by the OWNER REPRESENTATIVE. Grading shall be performed as to permit compliance with the ditching requirements in Section 2.9 of this document, or in the Scope of Work without creating an excessive number of over bends and sags in the pipe.

The CONTRACTOR shall conduct their operations in such manner as to keep dirt and dust from

rising into the atmosphere as much as practicable under the circumstances. Where required by any governmental body having jurisdiction, the CONTRACTOR shall wet down the right-of-way during their operations to aid in eliminating dust.

The CONTRACTOR will give consideration to the residents along the pipeline route. Blocking the

use of drives or public roads shall be minimized. Construction near homes will be done during normal work hours avoiding, to the extent possible, disruption due to noise at night.

2.7 Blasting

Blasting is defined as excavation of materials that must be broken up by means of drilling and blasting before excavation can be accomplished. Loose rock, which is partially disintegrated or in poorly cemented form, which can be loosened with a ripper pulled by a dozer, or that can be removed with a backhoe, will not be considered as blast excavation. Prior to blasting, the CONTRACTOR shall supply to the OWNER, a detailed blasting and safety procedure for approval. Blasting by the CONTRACTOR will not be permitted without prior approval from the OWNER.


Case No. U-15251 March 21, 2007


The OWNER’s agreement to allow the use of explosives shall not reduce the CONTRACTOR’s liability for personal injury or property damages. The CONTRACTOR shall not resort to the use of explosives in grading the right-of-way, trenching, or other operations, except when it is absolutely necessary to do so, and only after obtaining prior written approval from the OWNER. The OWNER shall have the right to order the removal of rock by jackhammers only in areas where use of explosives might endanger adjacent pipelines, buildings, or other existing structures.

Occupants of all buildings, stores, houses, or places of business within 300' of the blasting site shall be notified by the CONTRACTOR. Farmers shall be notified in sufficient time to protect any livestock nearby before any work is done. The OWNER or OWNER REPRESENTATIVE shall be present during blasting. The CONTRACTOR shall blanket all shots in congested areas to prevent damage or injury by flying debris. Shots shall also be blanketed to prevent damage to telephone and electrical power facilities, and to prevent scattering of stones in tillable fields, pastures, and lawns. Great care shall be exercised by the CONTRACTOR to prevent damage to underground structures, such as cables, conduits, and pipelines. This also applies to springs and underground watercourses.

Extreme care must be exercised by the CONTRACTOR when blasting near roads, railroads,

waterways, airports and other public access facilities. Proper notifications must be made to governmental agencies to ensure the safety and protection of the general public and facilities. Where the pipeline route parallels or crosses an electrical transmission corridor, a potential hazard exists whereby a premature initiation of blasting could be triggered by the stray current from an electrical field that may exist at these locations. The CONTRACTOR shall assess the hazard and may have to restrict the use of electrical detonation caps to a safe distance from such corridors. To avoid premature detonation of any blast circuit due to static electricity, blasting operations shall be suspended under high wind, dust, snow and dry conditions. Similarly, all moving equipment, including trucks used in the vicinity of electrical blasting operations, shall be grounded. All blasting operations shall be suspended, and all persons and equipment withdrawn immediately, at the first indication of an approaching electrical storm. Mobile radio transmitters, cellular phones, and pagers shall be kept well away from areas of electrical blasting operations, and signs shall be posted to have all transmitters near the site turned off.

Where, during blasting operations, loose rock is scattered over the right-of-way or adjacent property,

the CONTRACTOR shall clean up such rock and dispose of it to the satisfaction of the OWNER, the landowner, and their tenants.

Personnel thoroughly familiar with such work shall conduct blasting operations. Where governmental

authorities require licensed personnel and blasting permits, such requirements shall be observed. The CONTRACTOR shall obtain necessary permits and shall make proper notification to regulatory authorities in advance of any blasting. The CONTRACTOR shall provide the OWNER INSPECTOR with copies of all applicable permits obtained for blasting, prior to the commencement of blasting.

Explosives shall be stored in a locked magazine in accordance with practices specified by the United

States Bureau of Mines. Detonating caps shall not be stored with explosives, but shall be stored in a separate place in accordance with Bureau of Mines standards. Explosives shall not be primed or fused until immediately before use, and shall not be allowed to lay overnight in drilled holes.

Blasting in streams shall be scheduled to allow ample time for notification of local fish and wildlife

authorities. When required, representatives from such agencies will be present during blasting operations.


Case No. U-15251 March 21, 2007


The depth of the trench through rock shall be sufficient to allow for a minimum of 6 inch thickness padding under the pipe, with the minimum specified cover over the pipe maintained. The CONTRACTOR shall make a daily record of the locations, measurements, and quantities of rock excavated and furnish a copy to the OWNER INSPECTOR. Upon completion of blasting each day, the CONTRACTOR shall provide the OWNER with a copy of their daily blasting report(s) that includes the following data for each blast.

• Blasting Contractor license number • Date, time, and location of blast • Hole size, spacing, depth, layout, and volume of rock in shot • Delay type, interval, total number of delays, and holes per delay • Explosive type, specific gravity, energy release, lbs. of explosive per delay, and total lbs. of

explosive per shot • Power factor

2.8 Temporary Crossings The CONTRACTOR shall do all necessary grading and bridging at road, stream, bayou, and ditch

crossings, and at other locations where needed to permit the passage of its equipment. Bridging or access to fords of ditches and small streams shall not be constructed so as to interfere with the flow therein or unduly damage the banks thereof. The CONTRACTOR is responsible for moving its equipment and personnel across or around watercourses.

The CONTRACTOR shall be responsible for construction of temporary bridges to facilitate the work.

No public ditches or drains shall be filled or bridged, or used for passage of equipment, until the OWNER has secured approval of the authority having jurisdiction over same. The OWNER INSPECTOR is to receive a copy of the documentation of such approval.

The CONTRACTOR shall provide and maintain suitable crossings over the ditch, where necessary, to

permit property owners or tenants to pass or to move stock or equipment. Such crossings shall be a minimum of 1,000 feet apart when they are on the same property. Substantial temporary bridges shall be provided and placed across the ditch wherever necessary to minimize the inconvenience to the public.

Roadways shall not be blocked without proper notification of state, county, or other road authorities,

local emergency response organizations, and schools concerned. Traffic must be detoured at proper locations, and no roadway may be closed for any longer than necessary. Barricades, lanterns, and other warning devices must adequately protect all ditches across roadways.

Flagmen shall be provided when required by local authorities or requested by the OWNER.

Any expenses incurred from changing the working side from one side of the ditch to the other will be at the CONTRACTOR’s expense, unless directed by the OWNER. The OWNER may elect to define working side prior to award of the Contract.


Case No. U-15251 March 21, 2007


2.9 Ditching The CONTRACTOR shall employ such equipment and methods as may be required to excavate the

ditch, regardless of the type of soil or rock encountered, and regardless of the depth of excavation required and shall furnish all materials and supplies necessary for the completion and maintenance of the ditch, including water control, shoring, coffer dams, and sheet piling. Ditching and excavations shall meet all federal and state OSHA rules and regulations, including those cited under Title 29, Part 1926, Subpart P - Excavations.

Trenching or excavating shall not be performed until the OWNER REPRESENTATIVE has given

approval for the work to begin. The CONTRACTOR shall use an electronic detector up to 500 feet in front of the trenching or

excavating activities to find buried pipelines or utilities. There will be an organized patrol of 100 percent of the right-of-way during clearing and ahead of trenching to find the buried lines and to find all warning signs to verify staking.

The ditch line shall conform to the survey line and shall be continuous and as straight as possible to

minimize line length. The OWNER must approve deviations of more than two feet from the survey line and straight ditch line.

The bottom of the ditch shall be cut to uniform grade. At over-bends and side-bends, the

CONTRACTOR shall excavate the ditch to allow proper clearance between the inside bend of the pipe and the bottom or side of the ditch. Minimum clearance between side of ditch and pipe at side-bends shall be 8".

Where ditching is across or adjacent to roads, highways, railroads, irrigation or drainage ditches,

creeks, rivers, ravines, and other watercourses, farm terraces, and at points where the contour of the earth may require extra depth, the CONTRACTOR shall excavate to such additional depth as may be necessary to meet the requirements of the OWNER, landowner, and any public or private authority having jurisdiction over same. The extra depth is defined as "extra depth trench." The CONTRACTOR will provide extra depth trench at these locations at no additional charge.

For extra ditch depth required by right-of-way agreements, the OWNER REPRESENTATIVE, or

permits which were not provided to the CONTRACTOR in the bid documents or otherwise in writing prior to the CONTRACTOR submitting his proposal, the following will be the basis for compensation:

No additional compensation for the first 6 inches of additional depth. The CONTRACTOR shall be paid additional compensation for the extra depth trench

actually required, as measured from sag bend to sag bend, by applicable unit prices for extra depth provided in the CONTRACTOR’s proposal.

The CONTRACTOR may trench to additional depth at other places than those required with the

OWNER REPRESENTATIVE’s approval but without additional OWNER compensation.

The angle of intersection between the pipeline crossing and the railroad or highway to be crossed should be as near to 90 degrees as practicable. In no case shall it be less than 30 degrees, unless approved by the controlling authority and the OWNER.

Where required to prevent damage to valuable shrubbery, trees, lawns or other facilities, the CONTRACTOR shall ditch by hand. The cost shall be included in his total cost. Where these items are not defined prior to the CONTRACTOR submitting his proposal, the CONTRACTOR will be compensated on a per foot basis as defined in the unit pricing section of his proposal.

Ditch depth shall be measured from the average level of the original ground or the graded rights-of-way (whichever is lower) on each side of the ditch. Width shall be measured at the bottom of the ditch.

The CONTRACTOR’s attention is called to the fact that in some areas along a pipeline route, the

existence of a high water table may require the use of pumps, well-points, other means of de-watering and/or matting in order that the trench may be excavated and maintained. De-watering shall be in accordance with the project Soil and Erosion Control Plan.

The CONTRACTOR shall keep the ditch in good condition until the pipe is laid and the ditch closed.

The CONTRACTOR shall furnish and install material to maintain the sides of ditches and other excavations when there is a serious danger of caving.

The CONTRACTOR shall ensure the ditch is constructed according to OSHA specifications for side

slopes and shoring. At least one "competent" person, as defined by OSHA, shall be on-site during all excavations.

The CONTRACTOR, at the end of each workday, shall install security fence around all bore pit sites and areas of public accessibility per OSHA specifications.

The CONTRACTOR shall never place equipment in a position that could damage the pipe.


Case No. U-15251 March 21, 2007


The CONTRACTOR shall be required to maintain a safe ditch/hole, including the following where applicable:

Stair-stepping or terracing ditch walls Emergency exit routes out of ditch on both sides of pipe Control of spoil piles Observing various potential hazards such as weak walls Never working with bucket over laborers All edges of spoil piles shall be a minimum of 2' from the excavation. Comply with latest federal and state OSHA requirements for ditching and excavations

At least one qualified "competent" person, as defined by OSHA, shall be on-site during all excavations.

The CONTRACTOR shall inform the OWNER INSPECTOR of unusual findings or defects

discovered on excavated facilities, including, but not limited to: Mineral deposits on pipe Dents in pipe Foreign articles next to or touching pipeline Over-bend or sags Excavation in known areas of archaeological significance will not occur without the presence of the

OWNER REPRESENTATIVE and the representatives of any agencies having jurisdiction being given the opportunity to be present.

In the event fossil relics, artifacts, or other items of possible archaeological or cultural interest are

unearthed, the CONTRACTOR shall: Bring excavation to a halt. Notify the OWNER REPRESENTATIVE and, if present, the liaison officer for historical

preservation or the agency responsible for preservation of relics found at this site. Move around any such location until after the archaeological investigation is complete

and clearance from the appropriate agencies has been obtained. 2.10 Minimum Clearances The ditch shall be graded to pass under all pipelines, roads, and railroad crossings, ditches, canals,

streams, or any other obstruction unless otherwise specified by the OWNER. The CONTRACTOR shall notify, in writing, the OWNER and owners of all foreign underground structures at least 48 hours, as required by the local One-Call, or any other authority having jurisdiction prior to excavation near their facility.

In some cases, permission to pass over an existing line may be obtained. This will be noted on the

alignment sheets (or Construction Line List). Only the OWNER REPRESENTATIVE may approve such a crossing.

The CONTRACTOR shall maintain a minimum clearance of 24" between such lines or structures and

the line being laid, unless specified otherwise in the Scope of Work. Where this clearance is not feasible, the OWNER will specify the clearance to be maintained. The CONTRACTOR shall repair any pipe and/or pipe coating damaged by their work and shall exercise special care to protect and repair the pipe and/or pipe coating when in the vicinity of other pipelines. The method of repair must


Case No. U-15251 March 21, 2007


be approved by the OWNER and follow these specifications. The CONTRACTOR shall not be reimbursed for extra depth required to go under existing utilities. The CONTRACTOR shall not be reimbursed for repair work required on lines as a result of their excavation work.

Temporary underpinning, supports, and other protective devices necessary to keep interfering

structures intact shall be provided by the CONTRACTOR at no additional cost to the OWNER, and shall be of such design as to ensure against possible failure.

When pipeline construction is through low load bearing soil, such as encountered in marsh and water construction, the CONTRACTOR shall place a sufficient number of sack spacers between the pipeline and other structures or pipelines at no additional cost to the OWNER to ensure positive separation. When buoyancy is a concern, the CONTRACTOR shall install a sufficient number of buoyancy counter-weights consisting of concrete weights or other suitable commercially available material at locations specified by the OWNER.

Where drain tile is encountered, the CONTRACTOR shall excavate such that the pipeline may be laid

over or under such tile with a minimum clearance of 4" between the pipeline and the tile, or to such depths as required by a Right-of-Way Agreement.

When any drain tile is damaged, cut, or removed, a temporary repair shall be made immediately if

such repairs are determined necessary by the OWNER INSPECTOR. All tile shall be supported and replaced in accordance with attached Drawing STDM035.

Whenever a tile is cut, it shall be distinctly marked by placing a highly visible flag in the trench

spoil bank directly opposite such tile. This marker shall not be removed until the tile has been permanently repaired and such repairs have been approved by the OWNER INSPECTOR and land owner/tenant. Whenever a tile is cut and found plugged or damaged, the CONTRACTOR shall notify the OWNER INSPECTOR and landowner/tenant.

Before completing permanent tile repairs, all tile lines will be examined on each side of the trench for the entire width of the permanent right-of-way to check for tile that might have been damaged by construction equipment. The CONTRACTOR shall inspect the tile by inserting a drain probe, or equivalent, in accordance with Drawing STDM049. Backfill under tile plate after repair shall be tamped by hand. After the line is in the ditch and before backfilling, a permanent repair shall be completed to the satisfaction of the OWNER and landowner. Tile used in repair of drains is to be furnished by the CONTRACTOR, and shall be at least equivalent to existing tile.

2.11 Spoil Piles from Excavation The spoil bank from the ditching operation shall not be placed on any loose debris or foreign matter

that might become mixed with the soil excavated from the ditch. The spoil bank edge shall be located at least 2 feet from the excavation.

Across cultivated fields it may be necessary for gaps or openings to be cut in the spoil bank so that

excessive rains will not cause water to back up and flood the cultivated sections. Caution must be exercised in keeping open and useful all drain ditches and watercourses.

When the ditch is excavated through land where livestock is confined or through cultivated fields

where it is desirable for the landowner or tenant to have a passageway across the ditch, the CONTRACTOR shall provide safe, temporary bridges or provide other safe means of crossing the


Case No. U-15251 March 21, 2007


ditch at locations as required by the OWNER or landowner. Crossings, at a minimum, shall be in accordance with Section 2.8 of this document.

2.12 Double Ditching In areas where the topsoil is underlain by caliche or other type of subsoil that would be objectionable

to landowners if left on the surface, the CONTRACTOR shall double-ditch that portion of the line where required by right-of-way restrictions to do so. Double-ditching shall be defined as the process of removing all topsoil in such a manner that it can be stored separately from the subsoil before completing trench to proper depth and then backfilling the trench with the subsoil first and covering with topsoil after all subsoil has been replaced.

In areas where the topsoil is to be segregated, topsoil will be removed from the subsoil stockpile and trench areas. The depth of topsoil removal will include all of the “A” horizon down to the beginning of the subsoil “B” horizon, generally not to exceed a maximum of 12 inches. Topsoil removal up to a depth of 16 inches will be required in specially designated soils encountered along the pipeline right-of-way and identified in the construction plan. All topsoil will be stripped, stockpiled, and uniformly returned to restore the original soil depth profile in accordance with attached Drawing STDM042. During the clearing/construction phase, site-specific depths of topsoil stripping will be monitored and recorded by the COMPANY INSPECTOR. Where right-of-way construction requires cut-and-fill of the soil profile across grades, to the extent practicable, topsoil stockpiling will be located on the up-slope edge of the right-of-way in accordance with Drawing STDM035. Where topsoil cannot be separately stored on the up-slope side, suitable right-of-way space will be provided on the down-slope side to ensure the complete segregation of the topsoil from all cut-and-fill material.

2.13 Notifications Unless stated otherwise, the CONTRACTOR must notify all utility companies by telephone 48 hours

prior to the start of construction to advise them of the route of the proposed construction in order to obtain the assistance of companies in the location of their facilities, and so that they may be present during construction of the line in the vicinity of the utility company’s facilities.

The OWNER will give notification to the proper authorities (State, County, City, U.S. Army

Engineers, U.S. Coast Guard and/or any other authority, board, railroad, or political subdivision having jurisdiction over any part of the work) as may be mandatory or necessary in connection with the commencement, suspension, resumption and completion of the Work.

to the truck. During transport the tension of these slings shall be regularly checked. Pipe ends shall be protected from contact with other metallic materials.

Lifting equipment shall not be used to transport pipe. Hauling of materials shall be done

under valid permits from governing regulatory agencies. The CONTRACTOR shall secure written permission for hauling over public and private roads, fields, pastures, etc., off the OWNER’s right-of-way.

Ground surfaces where pipe is stacked shall have sufficient bearing capacity to support the

planned stack and reasonably flat. Stacked pipes shall be raised above ground surfaces to a height above the level where surface or runoff water may contaminate or flow into the pipe. Stacked pipes shall be prevented from movement by timber. These supports shall not be less than 4" wide. Supports must be spaced and structured under the pipe to prevent denting or bending to pipe. When stacked, the outer pipes of the bottom layer shall be wedged or clipped. Pipes of different diameter, manufacturer, wall thickness, or grade shall be stacked separately, each stack to be properly marked.

2.15 Stringing Pipe shall be strung along the right-of-way and left with proper stoppers or wedges to prevent pipe

from rolling over or away from the ditch. Pipe shall be placed on skids with proper protection, subject to the OWNER approval, to prevent damage to pipe or coating. Dragging, sliding, or dropping of the pipe is not permitted. Pipe shall not be placed directly on the ground at any time.

In stringing of pipe on the rights-of-way, hoist equipment shall be used to unload coated pipe from the

stringing trucks. All pipe handling equipment shall be designed so as to not cause damage to the pipe and coating.

The CONTRACTOR shall adequately anchor pipe on steep slopes and where right-of-way conditions

dictate, to prevent pipe from rolling or sliding on skids. The distance between the trench edge and the


Case No. U-15251 March 21, 2007


pipe string shall be planned to provide adequate space to work on the pipe along the trench, and to minimize the stresses in the pipe string during lowering-in.

The CONTRACTOR shall string the pipe in such a way that it will not interfere with public roads,

footpaths, tracks, etc. Suitable gaps shall be left at intervals, as necessary, to permit the passage of livestock and/or equipment across the right-of-way and as directed by the OWNER REPRESENTATIVE, or as specified in Right-of-Way Agreements. The CONTRACTOR shall not be reimbursed for reasonable gaps in the stringing process.

The CONTRACTOR shall lay out and measure the pipes to minimize the cutting of pipe producing

residual sections of pipe less than 30 inches or two pipe diameters, whichever is greater, in length. All pup joints shall be carried forward each day by the CONTRACTOR and welded into the line

during the next day’s laying operation. All pup joints equal to 30 inches or two pipe diameters, whichever is greater, shall be used in the pipeline. The CONTRACTOR shall install pup joints in the line between full lengths of pipe and avoid placing pup joints adjacent to each other. Pipe sections less than specified in this paragraph are permitted only when inserted between fittings on a fabricated assembly.

Pipe markings, including bar-coding (if used), shall be maintained on both ends of ALL full joints of

pipe until the pipe is installed in the ditch. Markings shall show the AFE number, purchase order number, joint number and length, heat number, grade, diameter, and wall thickness. For “pup-joints” the markings to be used in the field are the letter “P” followed by original joint number. For any pipe that is brought into permanent inventory, including less than full joints, all pipe markings shall conform to those for full joints. The CONTRACTOR shall be responsible for proper stringing and locating of the pipe by size, wall thickness, or as outlined in this Scope of Work. Any moving of pipe made necessary by non-compliance with the Scope of Work shall be at the CONTRACTOR’s expense.

2.16 Alignment Changes (Bends)

All regulated pipelines shall be designed and constructed in order to allow the passage of an internal inspection tool. Refer to Standard MPLDGN006 Induction Bend Design, Table 1 – Minimum Inner Diameter and Bend Radii For In-Line Inspection for minimum ID for a specific pipe diameter. The Scope of Work will describe any fabricated bends to be furnished by the OWNER. The CONTRACTOR shall cut, bevel, and weld the OWNER-supplied bends to match the proposed alignment of the piping, unless the OWNER furnishes specific bends for particular alignment changes.

In general, all horizontal and vertical changes in the alignment of the piping 15° and less shall be accomplished through the natural flexure of the pipe or by field cold bends.

All field bending shall be performed by cold bending methods, but caution shall be exercised to avoid buckling of pipe or weakening welds. All bends shall be made utilizing a bending machine approved by the OWNER. The OWNER REPRESENTATIVE or OWNER INSPECTOR may reject any bend containing buckles, wrinkles, cracks, flat spans, or other evidence of mechanical damage. The CONTRACTOR shall obtain the approval of the OWNER REPRESENTATIVE before any cold bend is made. All completed cold bends must be approved by the OWNER REPRESENTATIVE for minimum ID to pass the specified inspection tool. At the OWNER REPRESENTATIVE’s request, a mandrel shall be used to verify roundness. The CONTRACTOR shall not be reimbursed for rejected field bends.

The maximum angle of bending shall be one and one-half (1-1/2) degrees at any point.

The distance between points of bending shall not be closer than one pipe diameter.


Case No. U-15251 March 21, 2007


The centerline of the bend shall be no closer than six feet to the end of the joint.

If double-jointed pipe is used, a bend shall not be closer than one pipe diameter to the girth weld. If a bend is made one pipe diameter from the girth weld, the girth weld will be re-radiographed.

Pipe shall be inspected for coating damage after bending and damaged coating shall be repaired at the CONTRACTOR’s expense.

The midpoint of over-bends shall clear the high point of the trench bottom (8” to 12” maximum clearance), and sag bends shall be fitted snug to the bottom of the ditch. All bends that do not fit the bottom or side of the ditch shall be removed or adequately supported to the approval of the OWNER.

Test specimens will be bent to determine bend limitations, with the CONTRACTOR providing the labor to make the test bends, and the OWNER providing the pipe.

Any pipe buckled or gouged shall be cut out and replaced at the expense of the CONTRACTOR. Miter or wrinkled bends will not be permitted for any pipeline. Deflections caused by misalignment up to 3° are not considered miter bends.

In general, the curvature of all bends shall be distributed throughout as great a length of pipe as possible. The intent of these specifications is to minimize all possible bending of pipe by controlling the ditching operation so as to provide minimum curvature in the ditch.

A minimum radius of any field bend shall be as follows, except where otherwise noted:

NOMINAL PIPE SIZE

MINIMUM RADIUS OF

BEND IN PIPE O.D. (DIAMETERS) 12 inches and smaller

18D

14

21D 16

24D

27D 20 inches and larger

30D

The wall thickness and ovality along any portion of the bend created in the field bending procedure

shall meet all requirements of ASME B31.4 and API 5L for wall thickness variations and out of roundness. The OWNER INSPECTOR shall measure the bend’s wall thickness and ovality to ensure compliance. The maximum ovality allowed shall be +2.5% when measured by the following equation:

(Maximum ID - Minimum ID) x 100

Nominal ID For multiple bends within the same pipe joint, a minimum tangent length of 4' is required at both ends

of the cold bend, unless otherwise specified. No over-bends, sag or side bends shall be permitted on either side of any road crossing for a distance

of 200' from the road right-of-way line, unless approved by the OWNER. All pipe with seams shall be bent with the seam positioned along the neutral axis of the bend. The

longitudinal seam of the pipe shall be positioned in the bending machine so that the seam does not lie within the plane of bending and not pressed upon by the bending shoe. When making multiple axes bends in double-jointed pipe, it may be impossible to place both longitudinal seams in the neutral


Case No. U-15251 March 21, 2007


axes. When this occurs, bending stresses on both longitudinal seams shall be balanced and minimized by aligning both seams as close as practicable to their respective neutral axes. When laying a horizontal bend in the ditch, the seam will be positioned in the top half of the pipe.

All bends created through the process known as “cold” bending shall be hydrostatically tested in

accordance with Standard MPLCON021 Hydrostatic Test Execution. 2.17 Welding Welding shall be in accordance with the OWNER’s Standards MPLCON016 Production Welding,

MPLCON031 Production Welding Procedures, MPLCON032 Production Welder Qualification, MPLMNT030 Maintenance Welding, MPLMNT034 Maintenance Welding Procedures, & MPLMNT121 In-Service Welder Qualification.

The CONTRACTOR shall furnish the test apparatus for testing the welds, unless specified otherwise

in the Scope of Work. The OWNER will furnish the pipe for testing the welds, unless specified otherwise in the Scope of Work. The CONTRACTOR shall furnish labor, welding equipment, and expendable supplies for making the test welds and preparing the weld specimens for testing. The OWNER will furnish forms for recording test data, and these forms shall become permanent records of the project. All welding procedure(s) are subject to approval by the OWNER. In the case of pre-qualified welders, the CONTRACTOR shall provide the OWNER INSPECTOR with copies of all certification documents necessary to show that the welders being utilized have been approved for the welding procedures being used on the project; the CONTRACTOR/OWNER shall provide documentation that the welders proposed have been using the welding process for which they are qualified since the date they were qualified, without a lapse in use of the welding process of more than six consecutive months.

The CONTRACTOR shall furnish a sufficient number of skids or jack stands to support the pipe at

proper height for welding. The length of line in which only stringer beads and hot pass have been completed shall be limited to 1,000' in any one section at the end of each day’s work. Each joint of pipe (except that furnished with steel caps over both ends of each joint) shall be swabbed with a leather or canvas belt disc of the proper diameter satisfactory to the OWNER INSPECTOR, to remove dirt, mill scale, and other foreign substances before placing in alignment for welding. Unless otherwise stated, all line pipe will be furnished with beveled ends. All paint, rust, scale, dirt, oil, moisture, or other foreign material that may adversely affect the quality of the welds shall be removed from the bevel prior to welding.

Any suitable means that is approved by the OWNER REPRESENTATIVE may be used for cleaning

of bevels. Individuals utilizing grinders to clean bevels shall wear full-face shields. The CONTRACTOR shall cut and re-bevel all pipe and pipe ends that are defective or damaged beyond repair, and shall cut and bevel pipe at locations necessary to maintain correct alignment, spacing and offsets of the pipe. Field cutting and beveling to remove defective material will be paid for by the OWNER at rates included in the contract. Cutting and beveling to maintain alignment, spacing, or offsets, or to remove pipe damaged by the CONTRACTOR during any construction phase shall be done at the CONTRACTOR’s expense.

Torch cuts and bevels shall be made with machines that maintain a uniform angle and make cuts

perpendicular to the longitudinal axis of the pipe. The pipe ends shall have all burrs removed from both inside and outside edges. Oxides resulting from torch cutting shall be removed.

The OWNER may elect to have the CONTRACTOR cut out any production welds for testing. The CONTRACTOR shall bear all expense of cutting and replacing the initial test weld for each welder to check his workmanship. If additional tested welds meet the standards of acceptance of API Standard 1104, the OWNER will pay the CONTRACTOR for cutting out the welds, preparing specimens for testing, welding replacement into the pipeline and other work connected with the test at the price included in the contract. If the welds fail to meet the requirements of API Standard 1104,


Case No. U-15251 March 21, 2007


the CONTRACTOR shall bear all such costs. A work order or other report shall be prepared for each removed production weld, and shall be signed

by the OWNER REPRESENTATIVE and the CONTRACTOR’s MANAGER. The report shall describe the defect known or believed to exist in the weld, weld removal date, weld location by station number, test procedure, test results, and assignment of cost. The pipe inserted shall be 30" or two (2) pipe diameters long, whichever is greater, and shall match as to grade and wall thickness. Only one pup joint shall be installed between full lengths of pipe.

A suitable line-up clamp shall be used to ensure accurate alignment and spacing. Internal clamps shall be used, when feasible, and commercially available. Internal clamp tension shall not be released until the root bead is complete. External clamps may be used when it is impractical to use internal clamps. External clamp tension shall not be released until the root bead is at least 50% complete and uniformly spaced around the pipe circumference. If adverse weather conditions exist, or restraint of pipe from movement is difficult, the root bead shall be fully completed before clamp tension is released.

Qualified welders, using qualified welding procedures, shall make production welds. Welding speeds

shall not be significantly higher than welding speeds during procedure or welder qualification tests. The CONTRACTOR shall not use a bonus system or any other plan that would tend to encourage welding speeds beyond the reasonable capabilities of the welders.

All cracks and arc burns shall be cut-out. No grinding on the pipe is allowed. Any grinds outside the

bevel made without the OWNER INSPECTOR’s approval shall be assumed to be arc-burns and shall be cut out at the CONTRACTOR’s expense. The CONTRACTOR shall be responsible for notifying the OWNER INSPECTOR of any grind marks found on the pipe before welding begins on the subject joint. Any grinds which are not brought to the OWNER INSPECTOR’s attention prior to welding shall be deemed to have been caused by CONTRACTOR and shall be cut out at the CONTRACTOR’s expense.

The CONTRACTOR shall not be allowed to strip welds for external undercut, pinholes or cold lap on

the outside edge of cap. Caps shall be ground off and recapped in making the repair for such a defect. Repair of multiple defects in a weld is allowed; however, the OWNER INSPECTOR will allow only

one repair of the weld. Only one attempt to repair any specific defect will be allowed by the OWNER INSPECTOR. All repairs of welds will be done at the CONTRACTOR’s expense.

Welding shall not be performed when the OWNER INSPECTOR believes that weld quality may be

impaired by the prevailing weather conditions, such as rain, blowing sand or high winds. Short pipe lengths or pup joints, 30" or longer, that are cut off when tie-in welds are made, or that may

be produced as a result of other operations, shall be used by welding them into the line at locations where the pipe matches as to grade and wall thickness. Pup joints shall be installed between full lengths of pipe. Pup joints shall be carried forward each day by the CONTRACTOR and welded into the line during laying operations the next day.

2.18 Alignment of Seams When laying any pipe having a longitudinal seam, the pipe shall be turned so that the seam will be on

the upper surface of the line and within 20° from top center. Successive joints shall be rotated to right or left to avoid aligning the seams in adjoining pipe sections.

2.19 Closing Ends of Line The open end of the line shall be securely closed, using internal type closures or other acceptable

devices at the end of each day’s work to prevent the entrance of water, animals, trash, or any other obstructions, and shall not be opened until work is resumed. A mechanical device, other than


Case No. U-15251 March 21, 2007


welding, shall securely fasten end plugs or caps. Where the line is left apart at intervals for any reason, both ends shall likewise be securely closed. The manner of closure must be satisfactory to the OWNER.

2.20 Radiographic Inspection of Welds Radiographic inspection shall be performed in accordance with Standard MPLCON007 Radiographic

Inspection & Documentation. 2.21 Cleaning and Coating Field Joints (Yard Coated Pipe)

Cleaning and coating application shall be in accordance with Standard MPLCON002 Pipeline and Below-Grade Coatings.

2.22 Laying, Coating Inspection, and Lowering No line shall be lowered into the ditch without the OWNER’s prior approval.

The trench bottom, which is to receive the pipe ,shall be free of all sharp objects, stones, etc., such as might damage the coating during lowering-in. Where determined by the OWNER REPRESENTATIVE, the bottom 6" of the trench shall be padded with a layer of selected backfill prior to lowering-in of the pipe or a sufficient number of sand bags in the ditch bottom to hold pipe clear of all projections. The OWNER REPRESENTATIVE shall approve all backfilling materials and methods.

The pipe shall be laid in the trench as close to center as reasonably possible to allow for acceptable padding on each side.

Prior to lowering or installing, the CONTRACTOR shall furnish and operate a pulsating sparking-

type holiday detector to inspect the pipe. The inspection and repair of all holidays shall be in accordance with Standard MPLCON002 Pipeline and Below-Grade Coatings.

All pipe coating shall be inspected prior to lowering the pipe into the ditch (or pulling carrier pipe into

casing pipe) and any damaged coating that is discovered shall be repaired. The area shall be thoroughly re-cleaned, re-primed, re-coated, and re-inspected in accordance with Standard MPLCON002 Pipeline and Below-Grade Coatings. Caution shall be exercised in moving the pipe into position for lowering to avoid coating damage.

When lowering the line into the ditch, the CONTRACTOR shall support the pipe at frequent and

regular intervals so as to provide for necessary slack, utilizing skids to prevent pipe coating damage. Before lowering into the ditch, all skid marks and other damaged places shall be repaired to the

satisfaction of the OWNER. If any excess slack exists, the CONTRACTOR shall remove it by cutting out the excess slack and then re-welding the resulting two ends of the line together. This shall be done at the CONTRACTOR’s expense. Pipe shall be lowered in as soon as possible after necessary inspection, and should then be backfilled expeditiously.

A non-abrasive sling or cradle approved by the OWNER REPRESENTATIVE shall be used in

lowering all coated pipe sections, and the necessary amount of slack must be obtained without injury to the protective coating. In removing belt slings after pipe is lowered, the CONTRACTOR shall dig soil from around the slings to clear them, if necessary, to protect the pipe coating. The OWNER INSPECTOR shall determine whether the coating is damaged and will have the option to require the coating to be re-inspected with a Holiday Detector. Any coating injured in handling or lowering the pipe shall be repaired by the CONTRACTOR at the CONTRACTOR’s expense.


Case No. U-15251 March 21, 2007


Protective shields of plywood (or equivalent material) shall be placed along side walls of trench containing rock or other hard objects. These shields are to be taken out after the pipe has been covered with clean backfill, and is not subject to further movement.

All sag bends and side bends shall fit the ditch neatly with equal and adequate spacing, and overbends

shall be limited to 8" to 12" above the ditch bottom. 2.23 Padding and Backfill The trench shall not be backfilled prior to the OWNER REPRESENTATIVE’s approval. Approval to

proceed will be contingent on proper ditch depth, configuration for support of pipe, and if required, completion of as-built survey.

The CONTRACTOR shall backfill all excavations to the satisfaction of the OWNER. When a ditch

for a pipeline is backfilled, the backfill material and method must be approved by the OWNER REPRESENTATIVE and it must be backfilled in a manner that provides firm support under the pipe and prevents damage to the pipe and pipe coating from equipment or from the backfill material.

ALL SKIDS (AND DEBRIS, ESPECIALLY METALLIC) MUST BE REMOVED FROM THE DITCH PRIOR TO BACKFILL.

Unless stated otherwise, a minimum of 6" of acceptable backfill shall be placed in the bottom of the

trench and over top of pipe. It shall be made only with fine, loose earth or sand which shall not contain sharp gravel, rock, hard clods of earth, hard objects, vegetation, organic materials, or any other detrimental matter or foreign objects that could damage the pipe or coating. The remaining backfill shall be placed in a way that will not disturb the underlying padding material and will not injure the pipe.

The CONTRACTOR shall install direct burial pipeline warning tape to all pipeline sections installed by open trench. Warning tape shall be installed once the pipeline is lowered in place and backfill has been properly placed over top of pipe. The warning tape should be placed approximately equidistant between top-of-pipe and top-of-ditch.

Where topsoil is separated, subsoil will be placed in the ditch first to an even level and then followed by the topsoil. The topsoil shall be replaced per agreement with the landowner.

The equipment to be used for backfill shall be at the CONTRACTOR’s discretion and subject to the

OWNER’s approval, with all consideration being made to minimize working space requirements. Wherever practical in the judgment of the OWNER REPRESENTATIVE, the first backfill shall be the natural spoil bank and shall cover the pipe at least 12”. When the natural spoil bank is unsuitable for use as backfill around the pipe, special sifting and/or crushing techniques shall be applied to the spoil bank. If the special techniques are deemed unsuitable by the OWNER’s INSPECTOR, then acceptable backfill will need to be hauled in. Rock shield shall not be used as a substitute for padding, although if the backfill is particularly rocky, the CONTRACTOR may be required to place a rock shield mat over the previously padded pipeline before completing backfilling. The OWNER REPRESENTATIVE will approve any rock shield utilized by the CONTRACTOR prior to use. After this first backfill has been placed over the pipe, rock taken from the ditch may be replaced in the ditch provided that in cultivated areas no rocks of any greater concentration or size than existed prior to construction are placed into the top 18" of the backfill to interfere with plowing and cultivating. All surplus rock removed from the ditch shall be disposed of to the satisfaction of the OWNER, landowners, and tenants.

The CONTRACTOR shall employ any acceptable method approved by the OWNER

REPRESENTATIVE to compact the backfill without damaging the pipe or coating. Compacting of backfill shall not be done through rock land where coating might be damaged, nor through sections


Case No. U-15251 March 21, 2007


where drain tile is encountered and might be damaged. The CONTRACTOR, at the CONTRACTOR’s expense, shall repair damaged coating or flattened pipe.

All backfilling across drainage ditches, irrigation ditches, terraces, levees, railroads, public highways,

private drives, trails, roads, or streams shall be done in a manner satisfactory to any private or governmental authority having jurisdiction.

After the backfill is satisfactorily compacted, the remaining soil shall be spread and shaped over the

trench by means of equipment approved by the OWNER REPRESENTATIVE. All backfill shall be crowned to a height not less than 8", nor more than 12", above the adjacent

ground surface in accordance with Drawing STDM042. The CONTRACTOR shall compact all soil in areas designated by the OWNER REPRESENTATIVE

in order to minimize settlement of the pipeline installation. Except as designated for specific areas, disturbed ground shall be compacted to at least a level of

compaction equivalent to that of the surrounding terrain. Backfill placed directly over the pipeline shall be hand compacted if necessary until 18" of coverage is

achieved. After 18" of coverage is achieved, backfill may be wheel packed by the OWNER approved method.

If cinders or slag are encountered, 6" of sand shall be placed in the ditch bottom before lowering pipe,

being careful to exclude all foreign material. The CONTRACTOR shall fill the ditch with sand to a minimum of 6" above the pipe, with the remainder backfilled in the usual manner.

Throwing of welding rods, cans, old tin, broken skids, brush, trees, foreign substance, or refuse of any

kind into the ditch will not be permitted. All such materials and refuse must be removed from the right-of-way, or otherwise disposed of to the satisfaction of the OWNER, landowner, and/or his tenant.

The finished backfill must be sufficiently level to permit normal run off and irrigation through

irrigated fields. Harrowing, disking, or hand raking may be required to accomplish this. Where the use of borrowed dirt is necessary to crown the backfill to the required height, the manner and method of securing dirt shall be approved in writing by the OWNER, and those having jurisdiction of the property. All terraces, levees, and sides of drainage or irrigation canals, and all roads and highways that are open cut, shall be backfilled in layers not exceeding 8”, and each layer thoroughly compacted by suitable compacting equipment to provide a good bond between the undisturbed sides of the ditch and the new backfill material. Refer to Standard MPLCON017 Crossing Installation: Un-cased, Cased, Mechanically Reinforced for crossing and compaction specifications.

Where the backfilling is performed during freezing weather, or where frozen material is used, the

CONTRACTOR shall refill, redress and compact the backfill after the ground thaws. When backfilling on hillsides or sloping grounds, the CONTRACTOR shall provide furrows or

terraces across the pipeline ditch, as needed, to direct the flow of water into natural drainage courses and away from the pipeline ditch. In areas that the slope is less than 10:1 (ten horizontal to one vertical) and the area of construction is an uncultivated field, all right-of-way will be permanently seeded. In areas that the slope is greater that 10:1, the slope will be scarified by running tracked or wheeled construction equipment up and down or across the backfilled surface, respectively. Also, the construction surface shall be fertilized, permanently seeded and mulched, if construction is in an uncultivated field. Seeding activities should be performed in accordance with Section 2.26, Seeding, Sodding, and Planting of this document.


Case No. U-15251 March 21, 2007


Locations specified on the alignment sheets (or Construction Line List), or at points designated by the OWNER REPRESENTATIVE, will have sandbags or other means of stabilizing the ditch as shown on Drawing STDM037. Vehicle tracks will be graded out of the right-of-way. All sloping areas subject to erosion will have terraces. Terraces will be spaced according to the slope. Terraces will have a fall not to exceed one (1) foot in fifty (50) feet. Other areas along the pipeline right-of-way subject to erosion after being disturbed by construction activity are to be provided with sack breakers as shown on Drawing STDM038.

At roads, hillsides, creek banks, river banks, and other places where earth has been removed changing

the contour of the terrain during construction, the CONTRACTOR shall grade the area until the original profile has been restored.

Fence gaps will be closed as shown on Drawing STDM033.

Before final acceptance, and after trench settlement has been provided to the satisfaction of the

OWNER REPRESENTATIVE, pavement and drives designated by the OWNER REPRESENTATIVE shall be repaved with materials similar to the type removed and approved by the OWNER REPRESENTATIVE. When repaving, the existing pavement will be line cut, with the edge face of the old pavement left vertical. Ragged edges shall be trimmed to provide a substantially straight-line juncture between old and new surfaces.

The rigid (asphalt or concrete) pavement replacement shall be 12 inches wider on each side than the

ditch excavation to allow the new pavement to rest on undisturbed base. The pavement replacement shall be placed to conform to the existing pavement and drive grades. The type of materials used for replacement is given in Standard MPLCON015 Road Construction and Foundations.

2.24 Hydrostatic Testing See Standard MPLCON021 Hydrostatic Test Execution and Standard MPLDGN003 Hydrostatic Test

Design & Documentation. 2.25 Cleanup and Restoration The CONTRACTOR shall commence cleaning up of the right-of-way immediately behind the

backfill operation and will be required to complete this work within a reasonable time and distance behind the backfilling operation. The work area shall be restored as nearly as practical to its original condition.

No excavated material, in excess of the crown over the ditch, shall be left on the right-of-way. All

remaining excess excavated materials shall be hauled away and disposed of by the CONTRACTOR, at designated places approved by the OWNER REPRESENTATIVE.

Cleaning up the right-of-way shall include, but not necessarily be limited to, the following steps: 1. Clean up and disposal of all refuse, debris, waste, and rubbish such as brush, rock, skids, barrels,

drums, cans, etc., resulting from the construction operations. 2. Remove all equipment, tools, and facilities that were used in the performance of the work. 3. Remove to places designated by the OWNER REPRESENTATIVE all surplus and defective

ANSI 150# through ANSI 900# “CGI” Style - Internal Ring Winding Material: 304SS Inner Ring Material: 304SS Filler Material: Flexicarb (Grafoil) Oper. Temp.: -400 F to +1000 F

Note: For low stress piping applications, such as atmospheric tank nozzles, man ways, roof drains or some low pressure manifold installations where spiral wound gaskets are impractical or unnecessary, utilize 1/16" compressed non-asbestos fiber gasket.

All flanged connections made shall require new gaskets. Gaskets used for hydrostatic tests

on temporary fittings shall not be re-used.


Case No. U-15251 March 21, 2007


All flanged valve and skillet connections shall require gaskets on both sides of the valve,

flanges, or skillet. All mating surfaces shall be thoroughly cleaned of all old gasket material, debris, etc., to ensure even and continuous contact.

3.4.11 Bolting Standards

All flanged joints shall be fitted up so that the gasket contact faces bear uniformly on the gasket and are made up with uniform bolt stress. Alignment of parallelism tolerance should be limited to 3/32" on flanges up to 24" diameter and 1/16" on flanges above 24" diameter, except for flanges at pumping units where the maximum misalignment shall be ≤1/64 (0.015”). Tolerances will be measured face-to-face. See Standard MPLDGN002 Station & Mainline Piping.

In bolting gasketed, flanged joints, the gasket shall be properly compressed in accordance

with the design principles applicable to the type of gasket used. Upon being made up, the flange, gasket, and flange connection shall not leak product.

Stud and bolt tensioning can be achieved using a torque wrench or other tensioning devices

such as hydraulic wrenches. Raymond Bolt Gauge PDX934 or stress Micrometer may be used to measure the stresses in the studs, rather than torque values in critical applications identified by the OWNER. Uniform tensioning is as critical as stress or torque level.

The minimum stress on a bolt shall be 50% of the specified minimum yield strength of the

stud or bolt material. For ASTM A-193 B7 or ASTM A-320 L7 studs, the SMYS is 105,000 psi, which results in an allowable minimum stress level of 52,500 psi.

The maximum torque allowed on a particular bolt shall be 60% of the specified minimum

yield strength of the bolt material.

The CONTRACTOR may employ the use of "load washers" to ensure an adequate bolt stress.

All bolts or studs shall extend completely through their nuts and have full thread engagement

with a minimum of two (2) threads showing.

5.2 Special Safety Considerations for Pipeline Work Special precautions must be exercised near electric transmission lines. Where the pipeline route is

parallel or adjacent to electrical transmission lines, no equipment exceeding twenty feet in height will be used without the approval of the OWNER REPRESENTATIVE. In these locations, the CONTRACTOR will exercise care to avoid any contact between booms and the overhead lines. Equipment operators will also be warned to avoid guy wires (to avoid shaking the poles and causing contact between phases as the lines bounce). The CONTRACTOR will flag guy wires to make them more visible to the operators.

Pipe sections on skids shall be grounded at specified intervals to reduce induction. Welding will be done only in areas cleared of dry vegetation. The OWNER REPRESENTATIVE

will require fire guards in areas of dry vegetation. The CONTRACTOR will provide fire extinguishers, shovels, fire blankets, and other fire fighting equipment and materials with every crew.

Hand digging only is allowed near pipelines that are being crossed.


Case No. U-15251 March 21, 2007


Pipe will be handled only when experienced personnel are directing activities. When pipe is unloaded from trucks, special care will be taken when retaining straps are released, or when a truck is moved after retaining straps have been released and tensioned again.



Section #Code Sub heading Details

Marathon Pipe Line LLC's ("MPL") Proposed Construction

195.104 Variations in Pressure

If, within a pipeline system, two or more components are to be connected at a place where one will operate at a higher pressure than another, the system must be designed so that any component operating at the lower pressure will not be over-stressed.

The proposed new segment will have multiple over-pressure devices. At Samaria, a relief valve exists between the booster pump and mainline units that prevents the 150 ANSI equipment from experiencing over pressure events during a pump stop surge scenario. A control valve also exists at Samaria which keeps the mainline from exceeding a pressure of 1,440 psig. In addition, the mainline has a pressure transmitter which will shut down the units via the local PLC logic at the station in the event the MOP is exceeded. At the proposed transition facility, a pressure reducing control valve will be installed to ensure that the existing 16" is not exposed to pressure above its MOP of 946 psig because it will be directly tied to the new 24" pipe which will have an MOP of 1,440 psig. A relief valve at Detroit will protect station piping from mainline pressures.

195.106 Internal Design Pressure

(a) Internal design pressure for the pipe in a pipeline is determined in accordance with the following formula:

MPL proposes utilizing 24" pipe with .375 wall thickness and a SMYS of X65 to achieve a MOP of 1462 psig. The system will be limited by 600# ANSI fittings which have an MOP of 1440 psig.

P=(2St/D )×E ×FP =Internal design pressure in p.s.i. (kPa) gage.S =Yield strength in pounds per square inch (kPa) determined in accordance with paragraph (b) of this section.t =Nominal wall thickness of the pipe in inches (millimeters). If this is unknown, it is determined in accordance with paragraph (c) of this section.

D =Nominal outside diameter of the pipe in inches (millimeters).

E =Seam joint factor determined in accordance with paragraph (e) of this section.F =A design factor of 0.72, except that a design factor of 0.60 is used for pipe, including risers, on a platform located offshore or on a platform in inland navigable waters, and 0.54 is used for pipe that has been subjected to cold expansion to meet the specified minimum yield strength and is subsequently heated, other than by welding or stress relieving as a part of welding, to a temperature higher than 900 °F (482 °C) for any period of time or over 600 °F (316 °C) for more than 1 hour.(b) The yield strength to be used in determining the internal design pressure under paragraph (a) of this section is the specified minimum yield strength. If the specified minimum yield strength is not known, the yield strength to be used in the design formula is one of the following:(1)(i) The yield strength determined by performing all of the tensile tests of API Specification 5L on randomly selected specimens with the following number of tests:------------------------------------------------------------------------

Pipe size No. of tests------------------------------------------------------------------------Less than 6\5/8\ in (168 mm) nominal One test for each 200outside diameter. lengths.

6 \5/8\ in through 12\3/4\ in (168 mm One test for each 100through 324 mm) nominal outside diameter. lengths.

Larger than 12\3/4\ in (324 mm) nominal One test for each 50outside diameter. lengths.

------------------------------------------------------------------------(ii) If the average yield-tensile ratio exceeds 0.85, the yield strength shall be taken as 24,000 p.s.i. (165,474 kPa). If the average yield-tensile ratio is 0.85 or less, the yield strength of the pipe is taken as the lower of the following:(A) Eighty percent of the average yield strength determined by the tensile tests.(B) The lowest yield strength determined by the tensile tests.(2) If the pipe is not tensile tested as provided in paragraph (b) of this section, the yield strength shall be taken as 24,000 p.s.i. (165,474 kPa).(c) If the nominal wall thickness to be used in determining internal design pressure under paragraph (a) of this section is not known, it is determined by measuring the thickness of each piece of pipe at quarter points on one end. However, if the pipe is of uniform grade, size, and thickness, only 10 individual lengths or 5 percent of all lengths, whichever is greater, need be measured. The thickness of the lengths that are not measured must be verified by applying a gage set to the minimum thickness found by the measurement. The nominal wall thickness to be used is the next wall thickness found in commercial specifications that is below the average of all the measurements taken. However, the nominal wall thickness may not be more than 1.14 times the smallest measurement taken on pipe that is less than 20 inches (508 mm) nominal outside diameter, nor more than 1.11 times the smallest measurement taken on pipe that is 20 inches (508 mm) or more in nominal outside diameter.(d) The minimum wall thickness of the pipe may not be less than 87.5 percent of the value used for nominal wall thickness in determining the internal design pressure under paragraph (a) of this section. In addition, the anticipated external loads and external pressures that are concurrent with internal pressure must be considered in accordance with §§195.108 and 195.110 and, after determining the internal design pressure, the nominal wall thickness must be increased as necessary to compensate for these concurrent loads and pressures.(e) The seam joint factor used in paragraph (a) of this section is determined in accordance with the following table:

All mainline valves in line are tested to API 6D requirements. In addition, MPL requires the manufacturer to perform extended testing (up to two hours under pressure) which exceeds the 6D requirements.

195.12

Passage of Internal Inspection Devices

(a) Except as provided in paragraphs (b) and (c) of this section, each new pipeline and each line section of a pipeline where the line pipe, valve, fitting or other line component is replaced; must be designed and constructed to accommodate the passage of instrumented internal inspection devices.

The proposed pipeline segment will be designed to accommodate passage of instrumented internal inspection devices.

(b) This section does not apply to:(1) Manifolds;(2) Station piping such as at pump stations, meter stations, or pressure reducing stations;

(3) Piping associated with tank farms and other storage facilities;(4) Cross-overs;

3 of 8



(5) Sizes of pipe for which an instrumented internal inspection device is not commercially available;(6) Offshore pipelines, other than main lines 10 inches (254 millimeters) or greater in nominal diameter, that transport liquids to onshore facilities; and(7) Other piping that the Administrator under §190.9 of this chapter, finds in a particular case would be impracticable to design and construct to accommodate the passage of instrumented internal inspection devices.

(c) An operator encountering emergencies, construction time constraints and other unforeseen construction problems need not construct a new or replacement segment of a pipeline to meet paragraph (a) of this section, if the operator determines and documents why an impracticability prohibits compliance with paragraph (a) of this section. Within 30 days after discovering the emergency or construction problem the operator must petition, under §190.9 of this chapter, for approval that design and construction to accommodate passage of instrumented internal inspection devices would be impracticable. If the petition is denied, within 1 year after the date of the notice of the denial, the operator must modify that segment to allow passage of instrumented internal inspection devices.

195.126 Flange Connection

Each component of a flange connection must be compatible with each other component and the connection as a unit must be suitable for the service in which it is to be used.

MPL will only install stainless steel spiral wound gaskets, or better, on this pipeline.

195.134 CPM Leak Detection

This section applies to each hazardous liquid pipeline transporting liquid in single phase (without gas in the liquid). On such systems, each new computational pipeline monitoring (CPM) leak detection system and each replaced component of an existing CPM system must comply with section 4.2 of API 1130 in its design and with any other design criteria addressed in API 1130 for components of the CPM leak detection system.

The proposed pipeline segment will have CPM system that complies with API 1130 (2nd Addition Nov. 2002), concerning its design. 1) MPL uses the Real Time Transient Model (RTTM).2) MPL uses API 1149 to evaluate threshold levels.3) MPL also applies Slack Line Evaluation.

(a) Pipeline right-of-way must be selected to avoid, as far as practicable, areas containing private dwellings, industrial buildings, and places of public assembly.(b) No pipeline may be located within 50 feet (15 meters) of any private dwelling, or any industrial building or place of public assembly in which persons work, congregate, or assemble, unless it is provided with at least 12 inches (305 millimeters) of cover in addition to that prescribed in §195.248

The proposed pipeline will be designed to follow a route that minimizes overall impacts to property owners and the environment. MPL will be following existing utility and other developed linear corridors to minimize the overall impacts to property owners. In some instances, short re-routes have been selected, typically where homes or other structures have encroached on the existing pipeline and other pipeline, utility and developed corridors over the years. MPL is proposing to construct the pipeline segment at least 50 feet away from homes or other existing structures.

195.222Welders: Qualification of Welders

(a) Each welder must be qualified in accordance with section 6 of API 1104 (incorporated by reference, see §195.3) or section IX of the ASME Boiler and Pressure Vessel Code, (incorporated by reference, see §195.3) except that a welder qualified under an earlier edition than listed in §195.3 may weld but may not re-qualify under that earlier edition.

Welders will be qualified in the presence of a Certified Welding Inspector. All welders will be qualified for this proposed pipeline.

(b) No welder may weld with a welding process unless, within the preceding 6 calendar months, the welder has-

(1) Engaged in welding with that process; and

4 of 8



(2) Had one welded tested and found acceptable under section 9 of API 1104 (incorporated by reference, see §195.3).

195.226 Welding: Arc Burns

(a) Each arc burn must be repaired.(b) An arc burn may be repaired by completely removing the notch by grinding, if the grinding does not reduce the remaining wall thickness to less than the minimum thickness required by the tolerances in the specification to which the pipe is manufactured. If a notch is not repairable by grinding, a cylinder of the pipe containing the entire notch must be removed.

Arc burns made during construction will be cut out and replaced with new pipe.

(c) A ground may not be welded to the pipe or fitting that is being welded.

195.234Welds: Nondestructive Testing

(a) A weld may be nondestructively tested by any process that will clearly indicate any defects that may affect the integrity of the weld.

MPL requires 100% of all welds to be non-destructively tested, exceeding the 10% minimum requirement.

(b) Any nondestructive testing of welds must be performed-(1) In accordance with a written set of procedures for nondestructive testing; and(2) With personnel that have been trained in the established procedures and in the use of the equipment employed in the testing.(c) Procedures for the proper interpretation of each weld inspection must be established to ensure the acceptability of the weld under §195.228.

(d) During construction, at least 10 percent of the girth welds made by each welder during each welding day must be nondestructively tested over the entire circumference of the weld.(e) All girth welds installed each day in the following locations must be nondestructively tested over their entire circumference, except that when nondestructive testing is impracticable for a girth weld, it need not be tested if the number of girth welds for which testing is impracticable does not exceed 10 percent of the girth welds installed that day: (1) At any onshore location where a loss of hazardous liquid could reasonably be expected to pollute any stream, river, lake, reservoir, or other body of water, and any offshore area; (2) Within railroad or public road rights-of-way; (3) At overhead road crossings and within tunnels; (4) Within the limits of any incorporated subdivision of a State government; and (5) Within populated areas, including, but not limited to, residential subdivisions, shopping centers, schools, designated commercial areas, industrial facilities, public institutions, and places of public assembly.

(f) When installing used pipe, 100 percent of the old girth welds must be nondestructively tested.

(g) At pipeline tie-ins, including tie-ins of replacement sections, 100 percent of the girth welds must be nondestructively tested.

195.246 Installation of Pipe in a Ditch

(a) All pipe installed in a ditch must be installed in a manner that minimizes the introduction of secondary stresses and the possibility of damage to the pipe.(b) Except for pipe in the Gulf of Mexico and its inlets in waters less than 15 feet deep, all offshore pipe in water at least 12 feet deep (3.7 meters) but not more than 200 feet deep (61 meters) deep as measured from the mean low water must be installed so that the top of the pipe is below the underwater natural bottom (as determined by recognized and generally accepted practices) unless the pipe is supported by stanchions held in place by anchors or heavy concrete coating or protected by an equivalent means.

Pursuant to MPL's constructionstandards, a minimum of 6" of acceptablebackfill will be placed in the bottom of thetrench and over top of the pipe. Thebackfill will consist of fine, loose earth orsand which will not contain sharp gravel,rock, hard clods of earth, hard objects,vegetation, organic materials, or any otherdetrimental matter or foreign objects thatcould damage the pipe or coating. Theremaining backfill will be placed in a waythat will not disturb the underlyingpadding material and will not injure thepipe.
