regulations governing construction activities on the Project. Project specific information is provided 

in Appendix A. 

Significant changes to the implementation or design of this plan must be approved by the applicable 

Agency and Cameron Interstate Pipeline, LLC (Company). Significant changes shall be considered 

if the alternate measures: 

a. provide equal or better environmental protection; 

b. are necessary because a portion of this Plan is not feasible or is unworkable based on Projectspecific conditions; and/or 

c. are specifically required in writing by another Agency for the portion of the Project on its land or 

under its jurisdiction. 

Environmental permits will be acquired by Company unless otherwise specified in the Appendices 

or in the contract document. Please note permits issued by the appropriate Agency shall be 

appended to this document immediately upon receipt by Company. 

2. GENERAL CONDITIONS 

2.1 Environmental Training

Prior to entering the construction right-of-way, all individuals working on the project shall attend 

the environmental training session. All individuals working on the project shall sign an 

acknowledgement of having attended the appropriate level of training and shall display a hard 

hat sticker acknowledging attendance at environmental training. In order to insure successful 

compliance, personnel shall attend repeat or supplemental training, if compliance is not 

satisfactory or as new, significant issues arise. 

2.2 Environmental Inspection

 

Environmental Inspectors shall have the authority to stop activities that violate the environmental 

conditions of the Certificate, State and/or Federal environmental permit conditions, or landowner 

requirements; and to order appropriate corrective action.

site specific requirements. 

n. ensuring the repair of all ineffective temporary erosion control measures within twenty-four (24) 

hours 

of identification; 

o. keeping records of compliance with the environmental conditions of applicable permits and 

authorizations, and the mitigation measures proposed by Company in the application 

submitted to Federal or State environmental agencies during active construction and 

restoration; and 

p. identifying areas that should be given special attention to ensure stabilization and 

restoration after the construction phase. 

2.3 Access

All construction vehicles and equipment shall be confined to Company approved access roads 

and the construction right-of-way. If temporary alternative private roads for access are 

constructed they shall be designed to provide and allow proper drainage and shall be built to 

minimize soil erosion. Sufficiently sized gaps shall be left in all spoil and topsoil wind right-ofways at all temporary private access roads and obvious livestock or wildlife trails unless agreed 

with the Landowner prior to construction that these access points can be blocked during 

construction. All construction related private roads and access points to the right-of-way shall be 

marked with signs. Private roads not approved for construction shall also be marked. 

2.4 Appearance of Worksite 

The construction right-of-way shall be maintained in a clean neat condition at all times. At no 

time shall litter be allowed to accumulate at any location on the construction right-of-way. The 

contractor shall provide a daily garbage detail with each major construction crew to keep the

construction right-of-way clear of trash, pipe banding and spacers, waste from coating products, 

welding rods, timber skids, defective material and all construction and other debris immediately 

behind construction operations unless otherwise approved by Company. Paper from wrapping, 

coating products or lightweight items shall not be permitted to be scattered around by the wind. 

2.5 Non-Hazardous Waste Disposal 

Non-hazardous construction wastes include but are not limited to human waste, trash, pipe 

banding and spacers, waste from coating products, welding rods, timber skids, cleared 

vegetation, stumps, rock and all other construction debris. 

All waste which contains (or at any time contained) oil, grease, solvents, or other petroleum 

products falls within the scope of the oil and hazardous substances control, clean up and 

disposal procedures. This material shall be segregated for handling and proper disposal by the 

Contractor in accordance with Section 2.7. 

The Contractor shall be responsible for human wastes to be handled and disposed of 

exclusively by means of portable self-contained toilets during all construction operations. 

Wastes from these units shall be collected by a licensed Contractor for disposal only at licensed 

and approved facilities. 

The Contractor shall dispose of all drill cuttings and drilling mud at a Company approved 

location. Disposal options may include spreading over the construction right-of-way in an upland 

location approved by Company, hauling to an approved licensed landfill, or other site approved 

by Company. 

The Contractor shall remove all extraneous vegetative, rock and other natural debris from the 

construction right-of-way by the completion of clean-up. The Contractor shall remove all trash 

and waste from temporary Contractor’s yards, pipe yards and staging areas when work is 

completed at each location. The Contractor shall dispose of all waste materials at licensed 

waste disposal facilities. Wastes shall not be disposed of in any other fashion such as unpermitted burying or burning. 

2.6 Concrete Waste Management 

The contractor shall dispose of all concrete waste at a designated concrete disposal station 

approved by Company. Concrete wash water should not be discharged into waterways, 

wetlands, storm drains or ground water. The concrete washout area should be located at least 

100 feet from storm drains, open ditches, wetlands or waterbodies. The washout area can be 

constructed below or above grade depending on the location of the structure and must be 

approved by Company personnel prior to construction. Concrete washout facilities should be 

constructed with a minimum width and length of ten (10) feet with sufficient quantity and volume 

to contain all liquid and concrete waste generated by washout operations. The concrete 

washout structure can be constructed with straw bales, wood stakes and sandbags, earthen pit 

or other materials approved by the Environmental Inspector. 

When the temporary concrete washout facilities are no longer required the hardened concrete 

shall be removed and disposed of properly. The materials used to construct the washout facility 

shall be removed from the site and disposed of properly. 

 
Cameron Interstate Pipeline Expansion 

Environmental Plan 

Page 4 of 42

Washout facilities must be cleaned, or new facilities must be constructed and ready for use 

once the washout is seventy-five percent (75%) full. 

2.7 Hazardous Materials 

If hazardous materials or containers are encountered during construction, the Contractor shall 

stop work immediately and notify Company. The Contractor shall not restart work until clearance 

is granted by Company. The Contractor shall ensure that all hazardous and potentially 

hazardous materials are transported, stored and handled in accordance with all applicable 

regulations. Workers exposed to or required to handle hazardous materials shall also be trained 

in accordance with the applicable regulations and the manufacturer’s recommendations. The 

Contractor shall dispose of all hazardous materials at licensed waste disposal facilities. 

Hazardous materials shall not be disposed of in any other fashion such as un-permitted burying 

or burning. A unanticipated hazardous materials discovery plan is provided as Appendix 1. 

 

All transporters of oil, hazardous substances, and hazardous waste shall be licensed and 

certified according to the applicable state vehicle code. Incidents on public highways shall be 

reported to the appropriate agencies. All hazardous wastes being transported off-site shall be 

manifested. The manifest shall conform to DOT requirements and the appropriate state agency. 

The vehicles as well as the drivers must conform to all applicable vehicle codes for transporting 

hazardous wastes. 

2.8 Noise 

The Contractor shall minimize noise during non-daylight hours and within one (1) mile of 

residences or other noise-sensitive areas such as hospitals, motels or campgrounds. Contractor 

shall abide by municipal bylaws regarding noise near residential and commercial/industrial 

areas. The Contractor shall provide notice to Company if noise levels are expected to exceed 

bylaws for a short duration. The Contractor shall minimize noise in the immediate vicinity of 

herds of livestock or poultry operations, which are particularly sensitive to noise. If any project 

specific noise requirements are required they will be included attached to this environmental 

plan or included in the contract document prior to commencement of construction activities. 

2.9 Weed Control 

There are no project specific weed control requirements at this time however, if determined 

necessary they will be included in this plan prior to commencement of construction activities. 

2.10 Dust Control 

The Contractor shall at all times control airborne dust levels during construction activities to 

levels acceptable by Company. The Contractor shall employ water trucks, sprinklers or calcium 

chloride as necessary to reduce dust to acceptable levels. Utilization of calcium chloride would 

be limited to roads. Dust shall be strictly controlled where the work approaches dwellings, farm 

buildings and other areas occupied by people and when the pipeline parallels an existing road 

or highway. This shall also apply to access roads where dust raised by construction vehicles 

may irritate or inconvenience local residents. The speed of the Contractor vehicles shall be 

controlled while in these areas. The Contractor shall take appropriate precautions to prevent 

fugitive emissions caused by sand blasting operations from reaching any residence or public 

building. The Contractor shall place curtains of suitable material, as necessary, to prevent 
Cameron Interstate Pipeline Expansion 

Environmental Plan 

Page 5 of 42

windblown particles from sand blasting operations from reaching any residence or public 

building. 

2.11 Fire Prevention and Control 

The Contractor shall comply with all Federal, State, County and Local fire regulations pertaining 

to burning permits and prevention of uncontrolled fires. The following mitigative measures shall 

be implemented to prevent fire hazards and control of fires: 

 

 A list of relevant Authorities and their designated representative to contact shall be 

maintained on the construction site by construction personnel. 

 Adequate firefighting equipment in accordance with the regulatory requirements shall be 

available on site. 

 The level of forest fire hazard shall be posted at the construction office (where visible for 

all workers) and make them aware of it and related implications. 

 The Contractor shall provide equipment to handle any possible fire emergency. This 

shall include, although not be limited to, water trucks, portable water pumps, chemical 

fire extinguishers, hand tools such as shovels, axes, chain saws, etc. and heavy 

equipment adequate for the construction of fire breaks when required. 

 Specifically, the Contractor shall supply and maintain in working order an adequate 

supply of fire extinguishers for each crew that is engaged in work such as welding, 

cutting, grinding, burning of brush or vegetative debris, etc. 

 In the event of a fire, the Contractor shall notify local emergency response personnel. 

 All tree clearing activities are to be carried out in accordance with local rules and 

regulations for the prevention of forest fires. 

 Burning shall be done in compliance with state and/or county regulations and in the 

center of the right-of-way and in small piles to avoid overheating or damage to trees or 

other structures along the right-of-way. 

 Flammable wastes shall be removed from the construction site on a regular basis. 

 Flammable materials kept on the construction site must be stored in approved 

containers away from ignition sources. 

 Smoking shall be prohibited around areas with flammable products. 

 Smoking shall be prohibited on the construction site when the fire hazard is high. 

2.12 Adverse Weather 

The Contractor shall restrict certain construction activities and work in cultivated agricultural 

areas in excessively wet soil conditions to minimize rutting and soil compaction. In determining 

when or where construction activities should be restricted or suspended during wet conditions, 

the Contractor shall consider the following factors: 

 The extent that rutting may cause mixing of topsoil with subsoil layers or damage to tile 

drains 

 Excessive buildup of mud on tires and cleats 

 Excessive ponding of water at the soil surface 

 The potential for excessive soil compaction 

The Contractor shall implement mitigative measures to minimize rutting and soil compaction in 

excessively wet soil conditions which may include: 
Cameron Interstate Pipeline Expansion 

Environmental Plan 

Page 6 of 42

 Restricting work to areas on the spread where conditions are not prohibitive; 

 Using low ground weight or wide-track equipment or other low impact construction 

techniques; 

 Limiting work to areas that have adequately drained soils or have a cover of vegetation 

such as sod, crops or crop residues sufficient to prevent mixing of topsoil with subsoil 

layers or damage to drain tiles; or 

 Installing geotextile material or construction mats in problem areas. 

2.13 Wetland and Waterbody Identification 

Wetland and waterbody delineation was conducted using the current federal methodology 

(Interim Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Atlantic 

and Gulf Coastal Plain Region, October 2008). A wetland permit has been applied for and will 

be attached to the environmental plan or included in the contract document prior to 

commencement of construction activities. Construction methodology to be used in wetlands and 

waterbodies is located in Sections 5 through 8. 

2.14 Threatened and Endangered Species 

A threatened and endangered species survey was conducted within the Project boundary. Any 

conditions or considerations for federal or state listed species will be attached to this 

environmental plan or included in the contract document prior to commencement of construction 

activities. 

2.15 Cultural Resource Assessment 

A Cultural Resource Assessment was conducted within the Project boundary. Any conditions or 

considerations from any federal or state agency will be attached to this environmental plan or 

included in the contract document prior to commencement of construction activities. An 

Unanticipated Discovery Plan for the project is included in Appendix 3. 

3. UPLAND CONSTRUCTION 

3.1 Approved Areas of Disturbance 

The Contractor shall abide by the Project Specific FERC Upland Erosion Control, Revegetation, 

and Maintenance Plan as well any other local, state and federal permit guidelines set forth for 

the project. The Project Specific FERC Upland Erosion Control, Revegetation and Maintenance 

Plan is included as Appendix 4. Project-related ground disturbance shall be limited to the 

construction rights-of-way, extra work space areas, pipe storage yards, right-of-way and 

disposal areas, access roads and other areas as indicated on the approved alignment sheets. 

Any Project-related ground disturbing activities outside these approved areas, except those 

needed to comply with the erosion and sediment control practices specified in this Plan (e.g., 

slope breakers, energy-dissipating devices, dewatering structures, drain tile system repairs) will 

require notification and approval of appropriate local, state and federal agencies. All 

construction or restoration activities outside of the approved areas are subject to all applicable 

survey and mitigation requirements. 

3.1.1. Road Crossings and Access Points

Install and maintain safe and accessible conditions at all road crossings and access points 

during construction. 
Cameron Interstate Pipeline Expansion 

Environmental Plan 

Page 7 of 42

The use of crushed stone access pads is required where access points are located along 

paved roadways to reduce tracking of soils onto paved roads. Placement of the crushed 

stone onto geotextile fabric shall facilitate maintenance and removal. 

Road crossings shall be monitored when in use and after rain events. Roadways shall be 

swept as needed to ensure paved roadways are clear of accumulated soils. 

Construction materials placed on paved roadways shall be removed immediately following 

use. 

Reference Figures 2 - 4 for construction and placement details. 

3.1.2. Clearing

The objective of clearing is to provide a clear and unobstructed right-of-way for efficient 

construction of the pipeline. The following mitigative measures shall be implemented: 

 Construction traffic shall be restricted to the construction right-of-way and approved 

access roads. 

 Construction right-of-way boundaries including pre-approved temporary workspace shall 

be clearly staked to prevent disturbance to unauthorized areas. 

 If crops are present, they shall be mowed or disked to ground level unless an agreement 

is made for the Landowner to remove for personal use. 

 Burning is prohibited on cultivated land. 

 Construction right-of-way at timber shelterbelts in agricultural areas shall be reduced to 

the minimum necessary to construct the pipeline. 

 Chipping in wetland is prohibited. 

3.1.3. Topsoil Segregation Within Uplands

Unless the landowner or land management agency specifically approves otherwise, prevent 

the mixing of topsoil with subsoil by stripping topsoil from the full work area or from the 

trench and subsoil storage area (ditch plus spoil side method) in the following areas: 

 Areas specified in the contract by Company 

 residential areas; 

 hayfields; 

 other areas at the landowner's or land managing agency’s request; and 

 actively cultivated or rotated croplands and pastures. 

In residential areas importation of topsoil is an acceptable alternative to topsoil segregation. 

In deep soils (more than twelve (12) inches of topsoil), segregate at least twelve (12) inches 

of topsoil. 

In soils with less than twelve (12) inches of topsoil make every effort to segregate the entire 

topsoil layer. Where topsoil segregation is required, maintain separation of salvaged topsoil 

and subsoil throughout all construction activities. 

Segregated topsoil may not be used for padding the pipe. 
Cameron Interstate Pipeline Expansion 

Environmental Plan 

Page 8 of 42

Tree stumps and root wads should be segregated from topsoil and should not be used as 

backfill. Tree stumps should be considered construction debris and should be removed from 

the construction right-of-way. 

3.1.4. Grading 

The objective of grading is to develop a right-of-way that allows the safe passage of 

equipment and meets the bending limitations of the pipe. The following mitigative measures 

shall be implemented during grading unless otherwise approved or directed by Company 

based on site specific conditions or circumstances. However, work shall be conducted in 

accordance with applicable permits. 

 All grading shall be undertaken with the understanding that original contours and 

drainage patterns shall be re-established during clean up. 

 Agricultural areas that have been land formed with terraces shall be surveyed to 

establish pre-construction contours to be utilized for restoration of the terraces after 

construction. 

 On steep slopes, or wherever erosion potential is high, temporary erosion control 

measures shall be implemented. 

 Bar ditches adjacent to existing roadways that shall be crossed during construction shall 

be adequately ramped with grade or ditch spoil to prevent damage to the road shoulder 

and ditch. 

 Where the construction surface remains inadequate to support equipment travel, timber 

mats, timber riprap or other method shall be used to stabilize surface conditions. 

The Contractor shall limit the interruption of the surface drain network in the vicinity of the 

right of way, using the appropriate methods: 

 

 Providing gaps in the right-of-ways of subsoil and topsoil in order to prevent any 

accumulation of water on the land 

 Preventing obstructions in right-of-ways, right-of-way drains and ditches 

 Installing flumes and ramps in right-of-ways, and right-of-way drains and ditches to 

facilitate water flow across the construction right-of-way and allow for construction 

equipment traffic 

 Installing flumes over the trench for any watercourse where flow is continuous during 

construction 

3.1.5. Drain Tiles 

In the event that drain tiles are discovered during the course of construction Company and 

the Environmental Inspector shall be notified immediately and the following procedures shall 

be taken: 

 Mark locations of drain tiles damaged during construction. 

 Probe all drainage tile systems within the area of disturbance to check for damage. 

 Repair damaged drain tiles to their original or better condition. Do not use filter-covered 

drain tiles unless the local soil conservation authorities and the landowner agree. Use 

qualified specialists for testing and repairs. For new pipelines in areas where drain tiles 

exist or are planned, ensure that the depth of cover over the pipeline is sufficient to avoid 
Cameron Interstate Pipeline Expansion 

Environmental Plan 

Page 9 of 42

interference with drain tile systems. For adjacent pipeline loops in agricultural areas, 

install the new pipeline with at least the same depth of cover as the existing pipeline(s). 

3.2 Temporary Erosion Control (Uplands) 

Temporary erosion controls are crucial in maintaining compliance with the local, state and federal 

water quality regulations. Temporary erosion controls include, but are not limited to, temporary seed 

and mulch cover, silt fencing, staked hay or straw bales, straw wattles, erosion eels, temporary 

sediment traps, and temporary diversion berms. Temporary erosion controls shall be installed 

immediately prior to initial disturbance of the soil where practical. Where dense existing vegetation 

is present, install temporary erosion controls immediately following initial disturbance. Temporary 

erosion controls must be properly maintained throughout construction (on a daily basis) 

and reinstalled as necessary (such as after backfilling of the trench) until replaced by permanent 

erosion controls or restoration is complete. 

3.2.1. Temporary Slope Breakers (Uplands) 

Temporary slope breakers are intended to reduce runoff velocity and divert water off the 

construction right-of-way. Temporary slope breakers may be constructed of materials such 

as soil, silt fence, staked hay or straw bales, or sand bags. 

Install temporary slope breakers on all disturbed areas as necessary to avoid excessive 

erosion. Temporary slope breakers must be installed on slopes greater than 5 percent 

where the base of the slope is less than 50 feet from waterbody, wetland, and road 

crossings at the following spacing (closer spacing should be used if necessary): 

Percent Slope Spacing Distance (ft) 

5% – 15% 300 

> 15% – 30% 200 

> 30% 100 

Direct the outfall of each temporary slope breaker to a stable, well vegetated area. Where 

space allows, construct a small sediment trap at the base of slope breakers; otherwise 

construct or install an energy-dissipating device at the end of the slope breaker and off the 

construction right-of-way. 

Position the outfall of each temporary slope breaker to prevent sediment discharge into 

wetlands, water bodies, or other sensitive resources. 

Slope breakers may extend slightly (about four [4] feet) beyond the edge of the construction 

right-of-way to effectively drain water off the disturbed area. 

Reference Figure 5 for placement and construction details. 

 

3.2.2. Sediment Barriers (Uplands) 

Sediment barriers are intended to stop the flow of sediments and to prevent the deposition 

of sediments into sensitive resources. They may be constructed of materials such as silt 

fence, staked hay or straw bales, compacted earth (e.g., drivable berms across travel ways), 

sandbags, or other appropriate materials suitable for site conditions. 
Cameron Interstate Pipeline Expansion 

Environmental Plan 

Page 10 of 42

At a minimum, install and maintain temporary sediment barriers across the entire 

construction right-of-way at the base of slopes greater than five percent (5%) where the 

base of the slope is less than fifty (50) feet from a waterbody, wetland, or road crossing until 

revegetation is successful as defined in this Environmental Plan. 

Leave adequate room between the base of the slope and the sediment barrier to 

accommodate ponding of water and sediment deposition. 

Proper installation and regular maintenance of barriers is essential to ensure proper 

performance of devices. Sediment that has accumulated beyond one-half (1⁄2) the capacity 

of the device should be removed immediately. Undermining and bypassing must be 

repaired as needed to provide for adequate performance of devices. 

Where wetlands or water bodies are adjacent to and down-slope of construction work areas, 

install sediment barriers along the edge of these areas as necessary to prevent sediment 

flow into the wetland or waterbody. 

Reference Figures 6 and 7 for sediment barrier details. 

3.2.3. Silt Fence 

Silt fence shall be installed to control sheet and rill erosion along the boundary of the 

construction right-of-way to contain limited areas of disturbed soils. Silt fence is an effective 

measure to intercept runoff from upslope to form ponds that temporarily store runoff and 

allow sediment to settle out of the water and stay on the construction site. Silt fence can 

also prevent sheet erosion by decreasing the velocity of the runoff. 

Silt fences should be installed on the contour so that flow does not concentrate and cause 

bypassing, overtopping and/or failure. 

A silt fence is specifically designed to retain sediment transported by sheet flow from 

disturbed areas, while allowing water to pass through the fence. Silt fences should be 

installed to be stable under the flows expected from the site. 

Silt fences should not be installed across streams, ditches, waterways, or other 

concentrated flow areas. 

Silt fences are composed of geotextile fabric supported between steel or wooden posts. Silt 

fences are commercially available with geotextile fabric attached to the post and can be 

rolled out and installed by driving the post into the ground. 

Silt fences must be trenched in a minimum of six (6) inches at the bottom to prevent runoff 

from undermining the fence and developing rills under the fence. 

Silt fences are normally limited to situations in which only sheet or overland flow is expected. 

Silt fences normally cannot filter the volumes of water generated by channel flow. The 

following is a table of minimum requirements for silt fence materials: 
Cameron Interstate Pipeline Expansion 

Environmental Plan 

Page 11 of 42

The drainage area up gradient to the silt fence should not exceed one-quarter (1⁄4) acre per 

one hundred (100) linear feet of silt fence for non-reinforced fence and one-half (1⁄2) acre per 

one hundred (100) linear feet of reinforced fence. When all runoff from the drainage area is 

to be stored up gradient to the fence (i.e. there is no stormwater disposal system in place) 

the maximum slope length up gradient to the fence should not exceed those shown in the 

following table: 

Percent 

Slope 

Maximum Slope Length above Fence 

(ft) 

< 2% 100 

2% – 5% 75 

5% – 10% 50 

10% – 20% 25 

> 20% 15 

In areas where the slope is greater than ten percent (10%), a flat area length of ten (10) feet 

between the top of the slope to the fence shall be provided. 

Contractor shall install silt fences at the base of disturbed slopes across or adjacent to 

roadways, streams, wetlands, and anywhere else vegetative cover has been disturbed. 

When a construction right-of-way parallels a lake, stream, impoundment, or wetland, 

Contractor shall install a silt fence at the edge of the construction right-of-way to isolate and 

protect that feature from siltation. Contractor shall also employ these methods for paved 

roads and roadside trenches to minimize the flow of sediment onto or into these structures. 

Contractor shall install silt fences whenever disturbed slopes are of such degree, and 

features requiring erosion and sediment control protection are in such horizontal proximity to 

those slopes, as specified in the following table: 
Cameron Interstate Pipeline Expansion 

Environmental Plan 

Page 12 of 42

Percent Slope Proximity Distance (ft) 

< 5% 25 

5% – 15% 50 

16% – 30% 75 

> 30% 100 

Contractor shall install silt fence in all instances when vegetation is sparse within 150 ft. of a 

body of water that parallels or is adjacent to the construction right-of-way, and the disturbed 

slope is toward the water. 

Reference Figure 6 for construction details and diagrams. 

3.2.4. Temporary Trench Breakers (Uplands) 

Trench breakers are intended to slow the flow of subsurface water along the trench. Trench 

breakers may be constructed of materials such as sand bags or polyurethane foam. Do not 

use topsoil in trench breakers. 

An engineer or similarly qualified professional shall determine the need for and spacing of 

trench breakers. Otherwise, trench breakers shall be installed at the same spacing as an 

upslope of permanent slope breakers. 

In agricultural fields and residential areas where slope breakers are not typically required, 

install trench breakers at the same spacing as if permanent slope breakers were required. 

At a minimum, install a trench breaker at the base of slopes greater than 5 percent where 

the base of the slope is less than 50 feet from a waterbody or wetland and where needed to 

avoid draining a waterbody or wetland. 

Reference Figure 8 for placement details. 

3.3. Mulching 

The Contractor shall apply mulch on all areas with high erosion potential and on slopes greater than 

8 percent (8%) unless otherwise approved by Company based on site specific conditions or 

circumstances. The Contractor shall spread mulch uniformly over the area to cover at least 75 

percent (75%) of the ground surface at an approximate rate of two (2) tons/acre of straw, unless 

otherwise specified in Appendix A. Mulch application includes straw mulch or hydro mulch and 

tackifier. The Contractor shall not apply mulch in cultivated areas unless requested by the 

Landowner. The Contractor shall use mulch that is free of noxious weeds. The Contractor shall 

apply mulch immediately following seeding. The Contractor shall not apply mulch in wetlands 

unless otherwise specified in Appendix A. If a mulch blower is used, the majority of strands of the 

mulching material shall not be shredded to less than eight (8) inches in length to allow anchoring. 

The Contractor shall anchor mulch immediately after application to minimize loss by wind and 

water. When anchoring (straw crimping) by mechanical means, the Contractor shall use a tool 

specifically designed for mulch anchoring with flat, notched disks to properly crimp the mulch to a 

depth of approximately two (2) to three (3) inches. A regular farm disk shall not be used to crimp 

mulch. In soils possessing high erosion potential, the Contractor may be required to make two 

passes of the mulch-crimping tool; passes must be as perpendicular to the others as possible. 
Cameron Interstate Pipeline Expansion 

Environmental Plan 

Page 13 of 42

When anchoring with liquid mulch binders (tackifiers), the Contractor shall use a biodegradable 

tackifier derived from a vegetable-based, organic source. The Contractor shall apply mulch binders 

at rates recommended by the manufacturer. The Contractor shall limit the use of liquid mulch 

binders (tackifiers) for anchoring straw and the use of hydro mulch and tackifier to areas that are 

too steep or rocky to safely or effectively operate mechanical mulch-anchoring tools. 

3.4. Stringing (Uplands)

The objective of stringing is to place the line pipe along the construction right-of-way for bending 

and welding in an expedient and efficient manner. The Contractor shall utilize one or more of the 

following mitigation measures as applicable and when necessary to reduce compaction on the 

working side of the right-of-way or as directed by Company. However, all work shall be conducted 

in accordance with applicable permits. 

 Prohibiting access by certain vehicles 

 Using only machinery possessing low ground pressure (tracks or extra-wide tires) 

 Control access thus minimizing the frequency of all vehicle traffic 

 Hastening drainage through digging drainage ditch to re-establish surface drainage as required 

 Using timber riprap, matting, or geotextile fabric overlain with soil 

 Stopping construction entirely for a period of time 

3.5. Trenching (Uplands) 

The objective of trenching is to provide a ditch of sufficient depth and width with a bottom to 

continuously support the pipeline. During trenching operations, the following mitigative measures 

shall be implemented unless otherwise approved or directed by Company based on site specific 

conditions or circumstances. However, all work shall be conducted in accordance with applicable 

permits. 

 Segregate subsoil materials from topsoil in separate, distinct right-of-ways with a separation that 

shall limit any mixing of topsoil and subsoil during handling of these materials. 

 Gaps must be left in the spoil piles that coincide with breaks in the strung pipe to facilitate 

natural drainage patterns and to allow the passage of livestock or wildlife. 

 Trenching operation shall be followed as closely as practicable by lower-in and backfill 

operations to minimize the length of time the ditch is open. 

 Construction debris (e.g., welding debris) and other garbage shall not be deposited in the ditch. 

Should blasting be necessary for removal of rock, the following mitigation measures shall be 

implemented: 

i. Where blasting is required, operations shall be done accordingly to laws and 

regulations governing explosives. 

ii. Prior to using explosives the Contractor shall advise residents of the immediate area 

in order to prevent any risk of accidents or undue disturbances. 

iii. Blasting mats or subsoil shall be piled over the trench line to prevent any rocks from 

being blown outside the construction right-of-way. 

iv. Each blasting location shall be cleared and cleaned up before and after all blasting 

operations. 

v. Blasting shall be carried out during regular daylight working hours. 

3.6. Trench Dewatering/Well Points 
Cameron Interstate Pipeline Expansion 

Environmental Plan 

Page 14 of 42

The Contractor shall make all reasonable efforts to discharge trench water in a manner that avoids 

damage to adjacent agricultural land, crops and pasture. Damage includes, but is not limited to the 

inundation of crops for more than twenty-four (24) hours, deposition of sediment in ditches, and the 

deposition of gravel in fields or pastures. If trench dewatering is necessary in an area where salt 

damage to adjacent crops is evident, the Company Inspector shall conduct a field conductivity test 

on the trench water before it is discharged. If the conductivity of the trench water is determined to 

potentially affect soil quality, it shall not be discharged to areas where salt damage to crops is 

evident, but shall be directed as feasible so that water flows over a well vegetated, non-cropland 

area or through an energy dissipater and sediment barrier, then directed to nearby ditches or 

brackish wetlands or waterbodies. When pumping water from the trench for any reason the 

Contractor shall ensure that adequate pumping capacity and sufficient hose is available to permit 

dewatering as follows: 

 Water shall be diverted through a well vegetated area, a geotextile filter bag or a permeable 

berm (straw bale or Company approved equivalent); 

 trench water shall not be disposed of in a manner which could damage crops or interfere with 

the functioning of underground drainage systems; and 

 the Contractor shall screen the intake hose and keep the hose either one (1) foot off the bottom 

of the trench or in a container to minimize entrainment of sediment. 

3.7. Welding, Field Joint Coating, and Lower-In 

The objectives of welding, field joint coating and lower-in are to provide continuous segments of 

pipeline, to provide corrosion protection to the weld areas of the pipeline, and to place the pipeline 

in the center of the trench, without stress, at the required depth of cover. The following mitigative 

measures shall be followed during pipe welding, field joint coating, and lower-in, unless otherwise 

specified by Company in response to site specific conditions or circumstances. However, all work 

shall be conducted in accordance with applicable permits. 

 Shavings produced during beveling of the line pipe are to be removed immediately following this 

operation to ensure that livestock and wildlife do not ingest this material. When welding 

operations have created a continuous line of pipe that may be left on the right-of-way for an 

extended period of time due to construction or weather constraints, a gap in the welded pipe 

shall be provided to allow for access at farm road crossings and also for passage of livestock 

and/or wildlife. 

 Prior to the application of epoxy powder, urethane epoxy or other approved pipe coatings, a tarp 

shall be placed underneath the pipe to collect any overspray of epoxy powder and/or liquid 

drippings. Excess powder and/or liquid or other hazardous materials (e.g. brushes, rollers, 

gloves, etc.) shall be continuously collected and removed from the construction right-of-way. 

3.8. Padding and Backfilling 

The objective of padding (when required) and backfilling is to cover the pipe with material that is not 

detrimental to the pipeline and pipeline coating. The following mitigative measures shall be utilized 

during backfilling, unless otherwise approved or directed by Company based on site specific 

conditions or circumstances. All work shall be conducted in accordance with applicable permits. 

 Excessive water accumulated in the trench shall be eliminated prior to backfilling. 

 In the event it becomes necessary to pump water from open trenches, the Contractor shall 

pump the water and discharge it in accordance with Section 3.6. 
Cameron Interstate Pipeline Expansion 

Environmental Plan 

Page 15 of 42

 Prior to backfilling, all drain tile shall be permanently repaired, inspected and the repair 

documented as described in Section 5.5. 

 Prior to backfilling, trench breakers shall be installed on slopes where required to minimize the 

potential for water movement down the ditch and potential subsequent erosion. 

 In backfilling the trench, the stockpiled subsoil shall be placed back into the trench before 

replacing the topsoil. 

 Topsoil shall not be utilized for padding the pipe. 

 Backfilling shall be done without mixing spoil with topsoil. 

 Backfill shall be compacted to a minimum of ninety percent (90%) of pre-existing conditions 

where the trench line crosses tracks of wheel irrigation systems (pivots). 

 To reduce the potential for ditch line subsidence, spoil shall be replaced and compacted by 

backhoe bucket and/or by the wheels or tracks of equipment traversing down the trench. 

 The top four (4) feet or the actual depth of top cover, whichever is less, within the pipeline 

trench, bore pits, or other excavations shall not be backfilled with soil containing rocks of any 

greater concentration or size than existed prior to the pipeline's construction. 

4. RESTORATION AND CLEAN-UP (UPLANDS) 

Commence clean-up, final grading, topsoil replacement, and installation of permanent erosion control 

structures operations immediately following backfill operations. 

Grade the construction right-of-way to restore pre-construction contours and leave the soil in the proper 

condition for planting. Post-construction contours should match the adjacent properties. 

Tree stumps and forestry slash should be considered construction debris and should be removed from 

the construction right-of-way. 

Vegetative mulch created by forestry clearing activities may be utilized as mulch and may not remain 

stockpiled. 

Where adjacent to wetland crossings the Environmental Inspector shall be consulted to ensure upland 

restoration does not encroach on wetland areas. 

A travel lane may be left open temporarily to allow access by construction traffic if the temporary 

erosion control structures are installed, inspected and maintained. When access is no longer required, 

the travel lane must be removed and the right-of-way restored. 

Rock excavated from the trench may be used to backfill the trench only to the top of the existing 

bedrock profile. Rock that is not returned to the trench should be considered construction debris, unless 

approved for use as mulch or for some other use on the construction work areas by the land owner or 

land managing agency. 

Remove excess rock from at least the top twelve (12) inches of soil in all actively cultivated or rotated 

cropland and pastures, hayfields, and residential areas, as well as other areas at the landowner's 

request. The size, density, and distribution of rock on the construction work area should be similar to 

adjacent areas not disturbed by construction. The landowner may approve other provisions in writing. 

Remove construction debris from all construction work areas unless the landowner or land managing 

agency approves otherwise. 
Cameron Interstate Pipeline Expansion 

Environmental Plan 

Page 16 of 42

Remove temporary sediment barriers when replaced by permanent erosion control measures or when 

revegetation is successful. 

4.1. Permanent Erosion Control Devices (Uplands) 

4.1.1. Permanent Trench Breakers 

Trench breakers are intended to slow the flow of subsurface water along the trench. Trench 

breakers may be constructed of materials such as sand bags or polyurethane foam. Do not 

use topsoil in trench breakers. 

An engineer or similarly qualified professional shall determine the need for and spacing of 

trench breakers. Otherwise, trench breakers shall be installed at the same spacing as and 

upslope of permanent slope breakers. 

In agricultural fields and residential areas where slope breakers are not typically required, 

install trench breakers at the same spacing as if permanent slope breakers were required. 

At a minimum, install a trench breaker at the base of slopes greater than five percent (5%) 

where the base of the slope is less than fifty (50) feet from a waterbody or wetland and 

where needed to avoid draining a waterbody or wetland. 

Reference Figures 9 and 10 for construction and placement details. 

4.1.2. Permanent Slope Breakers 

Permanent slope breakers are intended to reduce runoff velocity, divert water off the 

construction right-of-way, and prevent sediment deposition into sensitive resources. 

Permanent slope breakers may be constructed of materials such as well vegetated earthen 

berms or functional equivalent. 

Construct and maintain permanent slope breakers in all areas, except cultivated areas and 

lawns, using spacing recommendations obtained from the local soil conservation authority or 

land managing agency. In the absence of written recommendations, use the following 

spacing unless closer spacing is necessary to avoid excessive erosion on the construction 

right-of-way: 

Percent 

Slope 

Spacing Distance (ft) 

5% – 15% 300 

> 15% – 30% 200 

> 30% 100 

Construct slope breakers to divert surface flow to a stable area without causing water to 

pool or erode behind the breaker. In the absence of a stable area, construct appropriate 

energy-dissipating devices at the end of the breaker. 

Slope breakers may extend slightly (about four [4] feet) beyond the edge of the construction 

right-of-way to effectively drain water off the disturbed area. Where slope breakers extend 

beyond the edge of the construction right-of-way, they are subject to compliance with all 

applicable survey requirements. 
Cameron Interstate Pipeline Expansion 

Environmental Plan 

Page 17 of 42

Where there is an existing right-of-way adjacent to the site, slope breakers should tie into 

existing breakers on an adjacent right-of-way, wherever practical. 

Reference Figure 5 for construction and placement details. 

4.2. Soil Compaction Mitigation 

Test topsoil and subsoil for compaction at regular intervals in agricultural and residential areas 

disturbed by construction activities. Conduct tests on the same soil type under similar moisture 

conditions in undisturbed areas to determine preconstruction conditions. Use penetrometers or 

other appropriate devices to conduct tests. 

Mitigate severely compacted soils in agricultural areas with deep tillage implements or other 

methods approved by the Company. 

Perform appropriate soil compaction mitigation in severely compacted residential areas. 

4.3. Revegetation

4.3.1. General 

Contractor shall be responsible for ensuring successful revegetation of soils disturbed by 

Project-related activities. Revegetation is considered successful when permanent vegetation 

density is at least seventy-five percent (75%) coverage throughout one hundred percent 

(100%) of the disturbed area (as compared to adjacent undisturbed vegetation), per the 

local, state and federal requirements. Additional measures may need to be taken to provide 

successful permanent revegetation. 

In residential areas, restore all ornamental shrubs and specialized landscaping in 

accordance with the construction line list. Restoration work must be performed by personnel 

familiar with local horticultural and turf establishment practices. 

4.3.2. Soil Additives and Seeding Requirements 

Contractor shall be required to revegetate all soil disturbed by construction except inundated 

wetlands. Contractor shall protect all new seeding from vehicular traffic during 

establishment. Contractor shall install permanent diversion dikes to channel runoff away 

from the seeded areas on slopes and to prevent erosion while vegetation is being 

established. 

If mulch was applied prior to seeding for temporary erosion control, the Contractor shall 

remove and dispose of the excess mulch prior to seedbed preparation to ensure that 

seedbed preparation equipment and seed drills do not become plugged with excess mulch; 

to ensure that seed can adequately contact the soil surface; and to ensure that seed 

incorporation or soil packing equipment can operate without becoming plugged with mulch. 

Contractor shall use a disk, field cultivator, drag, rake, or similar implement to prepare a 

smooth, firm, debris-free seedbed to a depth of six (6) inches. The soil shall not be worked 

when it is too wet. If soil conditions do not permit an adequate seedbed to be prepared, 

Contractor shall increase seeding rates by fifty percent (50%). 
Cameron Interstate Pipeline Expansion 

Environmental Plan 

Page 18 of 42

Contractor shall supply and apply agricultural or pelletized lime at a minimum rate of two (2) 

tons/acre, unless otherwise specified in the contract or by the Company, on all disturbed 

areas of the construction right-of-way, except wetlands. Lime shall be worked into the soil 

during application, or immediately thereafter, to prevent the possibility of exposure to storm 

water runoff. Suitable liming material includes dolomitic or calcitic materials. Liquid 

application is acceptable. 

Contractor shall supply and apply fertilizer as specified in contract or as advised by the 

Company to meet the nutrient requirements of the site conditions. The fertilizer shall be 

incorporated into the upper two (2) inches of the soil where conditions permit. Fertilizer shall 

not be applied to wetlands or waterbodies. 

Contractor shall supply and apply a seed mixture on all disturbed areas of the construction 

right-of-way, except wetlands, based on site specific seeding requirements identified in the 

contract or as specified by the Company. All seed must be used within twelve months of 

testing and incorporated by Contractor into the upper soil surface using a roller/packer. 

Seed shall be broadcast utilizing a cyclone seeder or with a drill seeder. The Contactor shall 

operate the cyclone seeder or drill seeder such that the specified seed rate is planted. 

Seeds shall be incorporated by a cultipacker to ensure good ground contact. 

In locations of extreme slope or very rocky ground conditions, Contractor shall hydro seed 

specific areas of the construction right-of-way as directed by Company. Hydro seeding shall 

apply seed at the rates specified by manufacturer for site conditions. Fertilizer shall be 

included with the seed, organic fiber, tackifier and water mixture. Organic fiber content shall 

be applied at the rate of three thousand (3,000) lbs/acres on an air-dry weight basis. The 

required tackifier shall consist of biodegradable, vegetable-based material and shall be 

applied at the rate recommended by the manufacturer. The seed, mulch and tackifier slurry 

shall be applied so that it forms a uniform, mat-like covering of the ground. 

Additional measures may be needed, such as soil testing, re-application of soil additives, reapplication of seed and mulch, to ensure permanent vegetation. 

4.3.3. Erosion Control Blankets

Erosion control blankets (ECBs) shall be applied where shown on the Construction 

Drawings or as directed by a Company representative. The Contractor shall anchor the 

ECBs with staples or approved devices. The Contractor shall use ECBs specified in 

Appendix A or otherwise directed by EI, however if no ECB is specified in Appendix A the 

Contractor should use a mat that is made of 100% biodegradable, double net, natural fiber 

such as straw or coir (coconut fiber). The Contractor shall prepare the soil surface and install 

the erosion control matting to ensure it is stable and the matting makes uniform contact with 

the soil of the slope face or stream bank underneath with no bridging of rills, gullies or other 

low areas. 

Reference Figure 11. 

5. WATERBODY CROSSINGS 

In the event that additional jurisdictional waterbodies are discovered during the course of construction 

Company and the Environmental Inspector shall be notified immediately and the following procedures 
Cameron Interstate Pipeline Expansion 

Environmental Plan 

Page 19 of 42

shall be taken. Project specific FERC Wetland & Waterbody Construction & Mitigation Procedures are 

included in Appendix 5. 

5.1 Notification Procedures and Permits 

Prior to construction activities, Contractor will provide a schedule detailing the dates of all 

waterbody and wetland crossing. Contractor will update the schedule at least weekly. Company 

will notify Agency, if required 

5.2 Installation 

The following procedures shall be followed for waterbodies within the construction right-of-way. 

Reference Figures 12 through 15 for placement, construction and maintenance details of 

Waterbody and Crossing practices. 

5.2.1. Extra Work Areas 

Extra Work Areas are identified on the construction alignments. 

Limit clearing of vegetation between extra work areas and the edge of the waterbody to the 

approved construction right-of-way. 

Limit the size of extra work areas to the minimum needed to construct the waterbody 

crossing. 

5.2.2. General Waterbody Crossing Procedures 

Comply with the local, state and federal permit terms and conditions. 

Removal of vegetation within wetlands shall be limited to the approved construction right-ofway. Existing contours shall not be altered. Rutting of soils (greater than twelve (12) inches) 

shall be repaired immediately. Stump removal shall occur only within the trench line. 

Mulching shall not occur within wetland or waterbody area. All vegetation cleared from 

wetland areas shall be moved to an upland area immediately following logging and clearing 

activities. 

Storage of construction related materials, such as river weights, shall not occur within 

wetlands. 

Construct crossings as close to perpendicular to the axis of the wetland or waterbody 

channel as engineering and routing conditions permit. 

If the pipeline parallels a wetland or waterbody, attempt to maintain at least fifteen (15) feet 

of undisturbed vegetation between the wetland and/or waterbody and the construction rightof-way. 

Where wetlands or waterbodies meander or have multiple channels, route the pipeline to 

minimize the number of wetland or waterbody crossings. 
Cameron Interstate Pipeline Expansion 

Environmental Plan 

Page 20 of 42

Maintain adequate flow rates to protect aquatic life, and prevent the interruption of existing 

downstream uses. 

Wetland or waterbody buffers (extra work area setbacks, refueling restrictions, etc.) must be 

clearly marked in the field with signs and/or highly visible flagging until construction-related 

ground disturbing activities are complete. 

Reference Figures 12 -15 for crossing details. 

5.2.3. Equipment Bridges for Waterbodies 

Only clearing equipment and equipment necessary for installation of equipment bridges may 

cross waterbodies prior to bridge installation. Limit the number of such crossings of each 

waterbody to one per piece of clearing equipment. 

 

Construct equipment bridges to maintain unrestricted flow and to prevent soil from entering 

the waterbody. Examples of such bridges include: 

a. equipment pads and culvert(s) 

b. equipment pads or railroad car bridges without culverts 

c. clean rock fill and culvert(s) 

d. flexi-float or portable bridges 

Additional options for equipment bridges may be utilized that achieve the performance 

objectives noted above. Do not use soil to construct or stabilize equipment bridges. 

Design and maintain each equipment bridge to withstand and pass the highest flow 

expected to occur while the bridge is in place. Field adjustments must be made to ensure 

adequate flow of stormwater below bridges. 

Align culverts to prevent bank erosion or streambed scour. If necessary, install energy 

dissipating devices downstream of the culverts. 

Design and maintain equipment bridges to prevent soil from entering the waterbody. Use 

geo-textile fabric under equipment pads where needed to prevent soil from moving up to 

surface of equipment pads or to prevent soil from falling into waterbody below. 

Construct and remove equipment pads in such a way to reduce disturbance of wetland soils 

beyond the limits of the equipment bridges. Avoid rutting of soils by the pads or the 

equipment outside of the bridge area. Rutting of soils (greater than twelve [12] inches) 

should be repaired immediately. 

Remove equipment bridges as soon as possible after permanent seeding unless the 

USACE, or its delegated agency, authorizes it as a permanent bridge. 

If there shall be more than one month between final clean-up and the beginning of 

permanent seeding and reasonable alternative access to the right-of-way is available, 

remove equipment bridges as soon as possible after final clean-up. 

Reference Figures 12 through 15 for placement of controls. 

5.2.4. Spoil Pile Placement and Control 
Cameron Interstate Pipeline Expansion 

Environmental Plan 

Page 21 of 42

All spoil from wetland or minor and intermediate waterbody crossings, and upland spoil from 

major waterbody crossings, must be placed in the construction right-of-way at least ten (10) 

feet from the water's edge or in additional extra work areas as needed. 

 

Use sediment barriers to prevent the flow of spoil or heavily silt-laden water into any wetland 

or waterbody. Should sediment migrate beyond sediment barriers steps shall be taken 

immediately to repair breaches in the barrier and to retrieve lost sediment. Should heavily 

silt-laden water seep from the barriers, immediate steps shall be taken to reduce flow and 

provide for adequate settling or filtration. Flocculants shall be utilized where additional 

filtration or settling is not practical due to space limitations. 

5.2.5. Dewatering Activities 

Trench dewatering shall occur as needed to prevent sediment laden water from entering 

wetlands, waterbodies or drainage channels that are beyond the immediate construction 

area. 

 

Trench water shall not be allowed to enter wetlands, waterbodies or drainage channels in 

such as way as to cause or contribute to scouring or sedimentation. 

Dewatering structures shall be limited by the following conditions: 

a. constructed within well vegetated uplands areas where engineering and routing 

conditions permit 

b. placed at the farthest location above wetlands, waterbodies or drainage channels as 

is practical 

c. located above natural sediment barriers such as existing well vegetated earthen 

berms or above sediment barriers constructed with appropriate materials 

d. within wetlands shall be removed immediately after use 

e. constructed and maintained to ensure discharge water quality meets the applicable 

regulatory standards 

Contractor shall supply adequate pumping equipment, hoses and supplies to each 

dewatering location for appropriate placement and maintenance of dewatering activities. 

Dewatering intake hoses shall be floated near the surface of trench water to reduce uptake 

of concentrated sediments within the trench water. This shall increase efficiency of pumps 

and filtration bags and increase discharge water quality. 

Discharge water clarity shall be visually monitored during dewatering activities. Should 

discharge water appears to be more cloudy than the receiving water or the water 

immediately upstream of dewatering location or fail to meet the water quality requirements 

for any reason, such as improper materials, placement, construction or maintenance of 

dewatering structures, dewatering activities shall cease immediately. Structures shall be 

moved, repaired, or replaced as requested by the Environmental Inspector. Flocculants shall 

be utilized where additional filtration or settling is not practical due to space limitations. 

Reference Figures 16 – 18 for dewatering details. 

5.2.6. Filter Bags for Dewatering 

Contractor shall supply and utilize filter bags, for purposes of dewatering, of the minimum 

specification as follows in the following table: 
Cameron Interstate Pipeline Expansion 

Environmental Plan 

Page 22 of 42

Parameter Minimum Specification 

Grab Strength > 200 lbs. 

Grab Elongation @ Break 100% (max) 

Puncture Resistance > 100 lbs. 

Trapezoid Tear Strength > 75 lbs. 

Burst Strength > 350 psi 

Apparent Opening Size (AOS) 70 – 100 

(U.S. sieve no. equivalent) 

Water Flow Rate > 105 gpm/sq. ft. 

Contractor shall have the option to procure pre-fabricated filter bags or to construct them onsite with the above specified geotextile fabric. If on-site construction is utilized, Contractor 

shall construct the filter bag to provide efficient sediment removal and resist seam failure. 

Dewatering rates shall be followed as described below for on-site constructed bags: 

Minimum Filter Dimensions Approximate Pumping Rate 

“X” (ft.) “Y” (ft.) Gallons per Minute 

10 20 300 

15 20 350 

20 20 400 

20 25 450 

25 25 500 

25 30 550 

30 30 600 

Contractor shall monitor the condition of the filter bags throughout the dewatering activities 

and shall ensure appropriate pumping levels shall be used in accordance with 

manufacturers recommended filter bag capacity. The table above shall be used in the 

absence of manufacturer’s recommendations. 

Contractor shall remove used filter bags from the construction right-of-way immediately 

following dewatering activities. 

Reference Figures 16 and 18 for filter bag diagram and details. 

5.2.7. Waterbody Crossing Methods 

Construction methods pertinent to waterbody crossings are presented below. Selection of 

the most appropriate method at each crossing shall be depicted on the construction 

drawings but may be amended or changed based on site-specific conditions (i.e., 

environmental sensitivity of the waterbody, depth, and rate of flow, subsurface soil 

conditions, and the expected time and duration of construction) at the time of crossing. In 

general the dry-ditch crossing technique should be utilized at all waterbody crossings less 

than 30’ wide with a perceivable flow at the time of the crossing. The open-cut (wet-ditch) 

method should be utilized at ephemeral streams and ditches when there is no perceivable 

flow at the time of crossing. Equipment to complete dry-ditch crossing will be onsite as a 

contingency in case that flow should begin during construction. Where required, horizontal 

directional drilling (HDD) will be used at designated major and or sensitive waterbody 

crossings. 
Cameron Interstate Pipeline Expansion 

Environmental Plan 

Page 23 of 42

5.2.8. Open-Cut Crossing Method (wet-ditch) 

An open-cut waterbody crossing will use methods similar to conventional upland open-cut 

trenching. This crossing method is typically used to cross waterbodies that are non statedesignated as well as intermediate and major waterbodies with substantial flows that cannot 

be effectively culverted or pumped around the construction zone using the dry-ditch crossing 

techniques. Non-state designated waterbodies typically include perennial warmwater 

streams not considered significant by the state, intermittent drainage ditches and stream 

and ephemeral stream or ditches. The open-cut construction method will evolve excavation 

of the pipeline trench across the waterbody, installation of a prefabricated segment of pipe, 

and backilling of the trench with native material. The construction zone is not isolated from 

the stream flow and the objective of this method is to complete the waterbody crossing as 

quickly as practical in order to minimize the duration of impacts to aquatic resources. There 

are two types of open-cut crossing methods: non-flowing open-cut method and the flowing 

open-cut method. 

The contractor shall utilize the non-flowing open cut crossing method (Figure 12) for all nonstate designated waterbody crossings (ephemeral, ditches, gullies, drains, swales, ect.) with 

no perceptible flow at the time of construction. Should site conditions change and the 

waterbody is flowing at the time of construction, the contractor shall utilize a dry-ditch 

crossing method unless otherwise approved by the Company. 

The flowing open-cut method is typically utilized on waterbodies 30’ or greater where dryditch crossing methods cannot be effectively utilized where dry-ditch crossing methods 

cannot be effectively utilized. Reference to Figure 13 for construction details. 

The open-cut crossing method shall be installed as follows: 

1. For minor waterbodies: 

a. Equipment bridges are not required at non state-designated fisheries (e.g. agricultural or 

intermittent drainage ditches). However, if an equipment bridge is used, it must be 

constructed in accordance with Section 5.2.2; 

b. Limit use of equipment operating in the waterbody to that needed to construct the 

crossing; 

c. Complete trenching and backfilling in the waterbody (not including blasting and other rock 

breaking measures) within 24 continuous hours; and 

d. If a flume is installed within the waterbody during mainline activities, it can be removed 

just prior to lowering in the pipeline. The 24-hour timeframe starts as soon as the flume is 

removed. 

2. For intermediate waterbodies: 

a. Limit use of equipment operating in the waterbody to that needed to construct the 

crossing. All other construction equipment must cross on an equipment bridge. 
Cameron Interstate Pipeline Expansion 

Environmental Plan 

Page 24 of 42

b. Attempt to complete trenching and backfill work within the waterbody (not including 

blasting and other rock breaking measures) within 48 continuous hours, unless site specific 

conditions make completion within 48 hours infeasible. 

3. For major waterbodies: 

a. Company will develop site-specific crossing plans to be submitted for approval by the 

FERC and the appropriate permitting agency; and 

b. Construct the crossing in accordance with the measures contained in this Plan to the 

maximum extent practical. 

5.2.9. Dry-Ditch Open-Cut Crossing Method 

The dry-ditch crossing method is divided into a flumed crossing method and a dam and 

pump crossing method. These methods are designed to maintain downstream flow at all 

times and to isolate the construction zone form the stream by channeling the water flow 

through a flume pipe or by damming the flow and pumping the water around the 

construction area. The overall objective is to minimize siltation of the waterbody and to 

facilitate trench excavation of saturated spoil. Unless approved otherwise by the appropriate 

state agency, pipeline construction and installation must occur using one of the two “dry” 

crossing methods for waterbodies state-designated as either coldwater or significant 

coolwater or warmwater fisheries. The flumed and dam and pump crossing methods are 

applicable to waterbodies up to 30 feet wide at the water’s edge at the time of construction. 

5.2.10. Dam and Pump Method (dry-ditch) 

The dam-and-pump method may be used for crossings of waterbodies where pumps can 

adequately transfer stream flow volumes around the work area, and there are no concerns 

about sensitive species passage. 

Implementation of the dam-and-pump crossing method must meet the following 

performance criteria: 

a. use sufficient pumps, including on-site backup pumps, to maintain downstream 

flows; 

b. construct dams with materials that prevent sediment and other pollutants from 

entering the waterbody (e.g., sandbags or clean gravel with plastic liner); 

c. screen and float pump intakes; 

d. prevent streambed scour at pump discharge; and 

e. monitor the dam and pumps to ensure proper operation for the duration of the waterbody 

crossing. 

Reference Figure 14 for construction diagram. 

5.2.11. Flume Crossing Method (dry-ditch) 

The flume crossing method requires implementation of the following steps: 

a. install flume pipe after blasting (if necessary), but before any trenching; 

b. use sand bag or sand bag and plastic sheeting diversion structure or equivalent to 

develop an effective seal and to divert stream flow through the flume pipe (minor 
Cameron Interstate Pipeline Expansion 

Environmental Plan 

Page 25 of 42

modifications to the stream bottom may be required in order to achieve an effective 

seal); 

c. properly align flume pipe(s) to prevent bank erosion and streambed scour; 

d. do not remove flume pipe during trenching, pipe laying, or backfilling activities, or initial 

streambed restoration efforts; and 

e. remove all flume pipes and dams that are not also part of the equipment bridge as soon 

as final clean-up of the stream bed and bank is complete. 

 

Reference Figure 15 for construction diagram. 

5.2.12. Horizontal Directional Drill (HDD) 

To the extent they were not provided as part of the planning process, for each waterbody or 

wetland that would be crossed using the HDD method, the Contractor shall provide a site 

specific plan to address each crossing. 

Unless otherwise specified in the site specific HDD plan, the procedures that the Contractor 

shall implement in the event of an inadvertent drilling mud release (“frac-out”) into any 

waters of the United States or Wetland areas within or adjacent to the construction right-ofway include containment of the inadvertent release and subsequent clean up, as necessary. 

A copy of the HDD contingency plan is located in Appendix 6. 

In the event that an inadvertent release is identified during the operation of a HDD, the 

Contractor shall immediately notify Company. Response options and actions shall be 

mutually evaluated and implemented, as necessary, to stop the release and prevent further 

inadvertent releases. Actions by the Contractor may include decreasing the drilling mud 

pressure and/or increasing the viscosity of the drilling mud. Company shall notify all 

applicable agencies as to the status of any release and subsequent clean-up. 

Company and the Contractor shall evaluate the frac-out to determine the need for clean-up 

and removal of the drilling mud. In general, typical, minor frac-outs within the construction 

right-of-way or adjacent wetland areas shall be contained and cleaned-up, unless such 

activity would cause further detrimental impacts to those areas. 

Upon identification of a frac-out, the Contractor shall take immediate measures to contain 

the release, depending on its location. If a frac-out occurs within the construction right-ofway, the Contractor shall immediately install silt fence to contain the release within an area 

adequate to facilitate potential clean-up procedures and protect adjacent wetland areas. 

The Contractor shall make every effort to contain frac-outs and releases within the 

construction right-of-way. 

In the event a frac-out occurs in a water body or watercourse, the Contractor shall, as 

approved by Company, install turbidity curtains within safely accessible open water areas to 

contain the release and decrease turbidity levels, thus allowing the drilling mud to settle to 

the bottom of the waterbody. During containment procedures, care shall be taken to 

minimize and limit impacts to adjacent areas. 

In the event a frac-out occurs in a water body or area outside the construction right-of-way, 

the Contractor shall notify Company immediately and shall not be permitted access to the 

spill without Company approval. 
Cameron Interstate Pipeline Expansion 

Environmental Plan 

Page 26 of 42

Wetlands that are not part of the permitted construction right-of-way but are disturbed as a 

result of Contractor frac-out and a Contractor response effort to a major drilling mud release 

(as directed by the permitting agencies) shall be restored to their pre-project elevations and 

conditions, including replanting. In the event that replanting is required, Company shall 

contact the appropriate regulatory agency(s) to determine revegetation requirements. 

Revegetation shall be conducted by the Contractor in accordance with requirements set 

forth by the regulatory agency(s). 

5.2.13. Crossings of Major Waterbodies, Scenic Rivers or Other 

Before construction, the project sponsor shall file with the FERC from the review and written 

approval by the Director a detailed, site specific construction plan and scaled drawings 

identifying all areas to be disturbed by construction for each major waterbody crossing. This 

plan should be developed in consultation with the appropriate state and federal agencies 

and should include extra work areas, spoil storage areas, sediment control structures, etc., 

as well as mitigation for navigational issues. The EI may adjust the final placement of the 

erosion and sediment control structures in the field to maximize effectiveness. 

5.3. Clearing (Waterbody) 

Except where rock is encountered and at non-flowing open cut crossings, all necessary 

equipment and materials for pipe installation must be on-site and assembled prior to 

commencing trenching in a waterbody. All staging areas for materials and equipment shall be 

located at least fifty (50) feet from the waterbody edge unless otherwise approved by Company. 

The Contractor shall preserve as much vegetation as possible along the waterbody banks while 

allowing for safe equipment operation. Clearing and grubbing for temporary vehicle access and 

equipment crossings shall be carefully controlled to minimize sediment entering the waterbody 

from the construction right-of-way. Clearing and grading shall be performed on both sides of the 

waterbody prior to initiating any trenching work. All trees shall be felled away from 

watercourses. Plant debris or soil inadvertently deposited within the high water mark of 

waterbodies shall be promptly removed in a manner that minimizes disturbance of the 

waterbody bed and bank. Excess floatable debris shall be removed above the high water mark 

from areas immediately above crossings. Vegetation adjacent to waterbodies which are to be 

installed by horizontal directional drill or boring methods shall not be disturbed except by hand 

clearing as necessary for drilling operations. 

5.4. Grading (Waterbody) 

The construction right-of-way adjacent to the waterbody shall be graded so that soil is pushed 

away from the waterbody rather than towards it when possible. In order to minimize disturbance 

to woody riparian vegetation within extra workspaces adjacent to the construction right-of-way at 

waterbody crossings, the Contractor shall maintain at a minimum a ten (10) foot vegetative 

buffer of waterbody banks. Grubbing shall be limited to the ditch line plus an appropriate width 

to accommodate the safe installation of vehicle access and the crossing to the extent 

practicable. 

5.5. Temporary Erosion and Sediment Control (Waterbody) 

Install sediment barriers immediately following the initial disturbance of the waterbody or 

adjacent upland. Sediment barriers must be properly maintained throughout construction and 
Cameron Interstate Pipeline Expansion 

Environmental Plan 

Page 27 of 42

reinstalled as necessary (such as after backfilling of the trench) until replaced by permanent 

erosion controls or restoration of adjacent upland areas is complete. The following specific 

measures must be implemented at stream crossings: 

a. Install sediment barriers across the entire construction right-of-way at all waterbody 

crossings where necessary to prevent the flow of sediments into the waterbody. In the 

travel lane these may consist of removable sediment barriers or drivable berms. 

Removable sediment barriers can be removed during the construction day but must be reinstalled after construction has stopped for the day and/or when heavy precipitation is 

anticipated; 

b. where waterbodies are adjacent to the construction right-of-way, install sediment barriers 

along the edge of the construction right-of-way as necessary to contain spoil and sediment 

within the construction right-of-way; and 

c. use trench plugs at all waterbody crossings, as necessary, to prevent diversion of water 

into upland portions of the pipeline trench and to keep any accumulated trench water out 

of the waterbody. 

5.6. Trenching (Waterbody) 

The following requirements apply to all waterbody crossings except those being installed by the 

non-flowing open cut crossing method. 

a. All equipment and materials shall be on site before trenching in the active channel of all 

minor waterbodies containing state designated fisheries, and in intermediate and major 

waterbodies. 

b. All activities shall proceed in an orderly manner without delays until the trench is 

backfilled and the stream banks stabilized. 

c. The Contractor shall not begin in-stream activity until the in-stream pipe section is 

complete and ready to be installed in the waterbody. 

d. The Contractor shall use trench plugs at the end of the excavated trench to prevent the 

diversion of water into upland portions of the pipeline trench and to keep any 

accumulated upland trench water out of the waterbody. 

e. Trench plugs must be of sufficient size to withstand upslope water pressure. The 

Contractor shall conduct as many in-stream activities as possible from the banks of the 

waterbodies. 

f. The Contractor shall limit the use of equipment operating in waterbodies to that needed 

to construct each crossing. 

g. The Contractor shall place all spoil from minor and intermediate waterbody crossings, 

and upland spoil from major waterbody crossings in the construction right-of-way at least 

fifty (50) feet from the water's edge, in additional extra work areas or as otherwise 

directed by Company. 

h. No trench spoil, including spoil from the portion of the trench across the stream channel, 

shall be stored within a waterbody unless the crossing cannot be reasonably completed 

without doing so. 

i. The Contractor shall install and maintain sediment barriers around spoil piles to prevent 

the flow of spoil into the waterbody. Spoil removed during ditching shall be used to 

backfill the trench usually with a backhoe, clamshell or a dragline working from the 

waterbody bank. Sand, gravel, rockshield, or fill padding shall be placed around the pipe 

where rock is present in the channel bottom. 

5.7. Pipe Installation (Waterbody) 
Cameron Interstate Pipeline Expansion 

Environmental Plan 

Page 28 of 42

 

The following requirements apply to all waterbody crossings except those being installed by the 

non-flowing open cut crossing method. 

a. The trench shall be closely inspected to confirm that the specified cover and that adequate 

bottom support can be achieved, and shall require Company approval prior to the pipe 

being installed. 

b. Such inspections shall be performed by visual inspection and/or measurement by a 

Company Representative. 

c. In rock trench, the ditch shall be adequately padded with clean granular material to provide 

continuous support for the pipe. 

d. The pipe shall be lowered into the trench and shall, where necessary, be held down by 

weights, as-built recorded and backfilled immediately to prevent the pipe from floating. 

e. The Contractor shall provide sufficient approved lifting equipment to perform the pipe 

installation in a safe and efficient manner. 

f. As the coated pipe is lowered in, it shall be prevented from swinging or rubbing against the 

sides of the trench. 

g. Only properly manufactured slings, belts and cradles suitable for handling coated pipe 

shall be used. 

h. All pipes shall be inspected for coating flaws and/or damage as it is being lowered into the 

trench. 

i. Any damage to the pipe and/or coating shall be repaired. 

5.8. Backfilling (Waterbody) 

 

The following requirements apply to all waterbody crossings except those being installed by the 

non-flowing open cut crossing method. 

a. Trench spoil excavated from waterbodies shall be used to backfill the trench across 

waterbodies. 

b. After lowering-in has been completed, but before backfilling, the line shall be reinspected 

to ensure that no skids, brush, stumps, trees, boulders or other debris is in the trench. 

c. If discovered, such materials or debris shall be removed from the trench prior to 

backfilling. 

d. For each major waterbody crossed, the Contractor shall install a trench breaker at the 

base of slopes near the waterbody unless otherwise directed by Company based on site 

specific conditions. 

e. The base of slopes at intermittent waterbodies shall be assessed on-site and trench 

breakers installed only where necessary. 

f. Slurred muck or debris shall not be used for backfill. 

g. At locations where the excavated native material is not acceptable for backfill or must be 

supplemented, the Contractor shall provide granular material approved by Company. 

h. If specified in the Construction Drawings, the top of the backfill in the stream shall be 

armored with rock riprap or bio-stabilization materials as appropriate. 

5.9. Stabilization and Restoration of Stream Banks and Slopes (Waterbody) 

The stream bank contour shall be re-established. All debris shall be removed from the 

streambed and banks. Stream banks shall be stabilized and temporary sediment barriers shall 

be installed within twenty-four (24) hours of completing the crossing if practicable. Approach 

slopes shall be graded to an acceptable slope for the particular soil type and surface run off 

controlled by installation of permanent slope breakers. Where considered necessary, the 
Cameron Interstate Pipeline Expansion 

Environmental Plan 

Page 29 of 42

integrity of the slope breakers shall be ensured by lining with erosion control blankets. 

Immediately following reconstruction of the stream banks, the Contractor shall install seed and 

flexible channel liners on waterbody. If the original stream bank is excessively steep and 

unstable and/or flow conditions are severe or if specified on the Construction Drawings, the 

banks shall be stabilized with rock riprap, gabions, stabilizing cribs, or bio-stabilization 

measures to protect backfill prior to reestablishing vegetation. Stream bank riprap structures 

shall consist of a layer of stone, underlain with approved filter fabric or a gravel filter blanket. 

Riprap shall extend from the stabilized streambed to the top of the stream bank, where 

practicable, native rock shall be utilized. Bio-stabilization techniques may be considered for 

specific crossings. The Contractor shall remove equipment bridges as soon as possible after 

final clean up. 

6. RESTORATION (WATERBODY) 

Use clean gravel or native cobbles for the upper one (1) foot of trench backfill in all waterbodies that 

contain coldwater fisheries. 

 

For open-cut crossings, stabilize waterbody banks and install temporary sediment barriers within 

twenty-four (24) hours of completing in-stream construction activities. 

For dry-ditch crossings, complete streambed and bank stabilization before returning flow to the waterbody 

channel. 

Return all waterbody banks to preconstruction contours or to a stable angle of repose as approved by 

the Environmental Inspector. 

Application of riprap for bank stabilization must comply with USACE or any other Agency permit terms 

and conditions. 

Unless otherwise specified by Agency permit, limit the use of riprap to areas where flow conditions 

preclude effective vegetative stabilization techniques such as seeding and erosion control fabric. 

Revegetate disturbed waterbody areas with conservation grasses and legumes or native plant species. 

Install a permanent slope breaker across the construction right-of-way at the base of slopes greater 

than five percent (5%) that are less than fifty (50) feet from the waterbody, or as needed to prevent 

sediment transport into the waterbody. In addition, install sediment barriers as outlined in the Plan. In 

some areas, with the approval of the Environmental Inspector, an earthen berm may be suitable as a 

sediment barrier adjacent to the waterbody. 

Above-mentioned restoration requirements also apply to those perennial or intermittent streams not 

flowing at the time of construction. 

7. POST- CONSTRUCTION MAINTENANCE (WATERBODY) 

Limit vegetation maintenance adjacent to waterbodies to allow a riparian strip at least twenty-five (25) 

feet wide, as measured from the waterbody's mean high water mark, to permanently revegetate with 

native plant species across the entire construction right-of-way. However, to facilitate periodic pipeline 

corrosion/leak surveys, a corridor centered on the pipeline and up to ten (10) feet wide may be 

maintained in an herbaceous state. 
Cameron Interstate Pipeline Expansion 

Environmental Plan 

Page 30 of 42

In addition, trees that are located within fifteen (15) feet of the pipeline that are greater than fifteen (15) 

feet in height may be cut and removed from the permanent right-of-way. 

Do not use herbicides or pesticides in or within one hundred (100) feet of a waterbody except as 

allowed by the appropriate land management or state agency. 

8. WETLAND CROSSINGS 

8.1. General 

Where applicable, procedures for waterbody crossings should also be considered for wetland 

crossings. Project specific FERC Wetland & Waterbody Construction & Mitigation Procedures 

are located in Appendix 5. 

8.1.1. Field Markings 

Wetland boundaries and buffers must be clearly marked in the field with signs and/or highly 

visible flagging until construction-related ground disturbing activities are complete. Wetland 

boundaries marking shall be maintained as needed to ensure visibility throughout the 

Project. 

8.1.2. Alternative Crossing Plan 

Implement the measures of FERC’s Wetland and Waterbody Construction And Mitigation 

Procedures in the event a waterbody crossing is located within or adjacent to a wetland 

crossing. If all measures of FERC’s Wetland and Waterbody Construction and Mitigation 

Procedures cannot be met, Company must file with the applicable local, state and federal 

agencies a site-specific crossing plan for review and written approval before construction. 

This crossing plan shall address at a minimum: 

a. spoil control 

b. equipment bridges 

c. restoration of waterbody banks and wetland hydrology 

d. timing of the waterbody crossing 

e. method of crossing 

f. size and location of all extra work areas 

8.2. Installation (Wetlands) 

8.2.1. Extra Work Areas and Access Roads (Wetlands) 

Limit clearing of vegetation between extra work areas and the edge of the wetland to the 

approved construction right-of-way. 

The construction right-of-way may be used for access when the wetland soil is firm enough 

to avoid rutting or the construction right-of-way has been appropriately stabilized to avoid 

rutting (e.g., with prefabricated equipment mats, or terra mats). 

In wetlands that cannot be appropriately stabilized, all construction equipment other than 

that needed to install the wetland crossing shall use access roads located in upland areas. 

Where access roads in upland areas do not provide reasonable access, limit all other 

construction equipment to one pass through the wetland using the construction right-of-way. 
Cameron Interstate Pipeline Expansion 

Environmental Plan 

Page 31 of 42

Company & Agency only approved access roads, other than the construction right-of-way, 

that can be used in wetlands are those existing roads that can be used with no modification 

and no impact on the wetland. 

8.2.2. General Wetland Crossing Procedures 

Comply with Project Specific (FERC) Wetland and Waterbody Construction and Mitigation 

Procedures (Appendix 5) as well as USACE or any other permit terms and conditions. 

Construct crossings as close to perpendicular to the axis of the wetland or waterbody 

channel as engineering and routing conditions permit. 

If the pipeline parallels a wetland or waterbody, attempt to maintain at least fifteen (15) feet 

of undisturbed vegetation between the wetland and/or waterbody and the construction rightof-way. 

Where wetlands or waterbodies meander or have multiple channels, route the pipeline to 

minimize the number of wetland or waterbody crossings. 

Maintain adequate flow rates to protect aquatic life, and prevent the interruption of existing 

downstream uses. 

Wetland or waterbody buffers (extra work area setbacks, refueling restrictions, etc.) must be 

clearly marked in the field with signs and/or highly visible flagging until construction-related 

ground disturbing activities are complete. 

Removal of vegetation within wetlands shall be limited to the approved construction right-ofway. Existing contours shall not be altered. Rutting of soils (greater than twelve [12] inches) 

shall be repaired immediately. 

Mulching shall not occur within wetland or waterbody area. All vegetation cleared from 

wetland areas shall be moved to an upland area immediately following logging and clearing 

activities. 

Storage of construction related materials, such as river weights, shall not occur within 

wetlands. 

Assemble the pipeline in an upland area unless the wetland is dry enough to adequately support 

skids and pipe. 

Trench operations shall be limited to periods of time when significant precipitation is not 

anticipated during the crossing procedures. 

Limit construction equipment operating in wetland areas to that needed to clear the 

construction right-of-way, dig the trench, fabricate and install the pipeline, backfill the trench, 

and restore the construction right-of-way. 

Limit the length of time that topsoil is segregated and the trench is open to less than twentyfour (24) hours. If backfill operations cannot be completed within twenty-four (24) hours due 

to site conditions beyond the control of Contractor, the Environmental Inspector shall be 

notified in advance. 
Cameron Interstate Pipeline Expansion 

Environmental Plan 

Page 32 of 42

Cut vegetation just above ground level, leaving existing root systems in place, and remove it 

from the wetland for disposal. 

Limit pulling of tree stumps and grading activities to directly over the trench line. Do not 

grade or remove stumps or root systems from the rest of the construction right-of-way in 

wetlands unless the Chief Inspector and Environmental Inspector determine that safetyrelated construction constraints require grading or the removal of tree stumps from beneath 

the working side of the construction right-of-way. 

Segregate the top one (1) foot of topsoil from the area disturbed by trenching, except in 

areas where standing water is present or soils are saturated or frozen. Immediately after 

backfilling is complete, restore the segregated topsoil to its original location. 

Restore disturbed areas to pre-construction contours as recorded in pre-construction 

wetland survey. 

Do not use rock, soil imported from outside the wetland, tree stumps, or brush riprap to 

support equipment on the construction right-of-way. 

If standing water or saturated soils are present, or if construction equipment causes ruts or 

mixing of the topsoil and subsoil in wetlands, use low-ground-weight construction 

equipment, or operate normal equipment on timber riprap, prefabricated equipment mats, or 

terra mats. 

Do not cut trees outside of the approved construction work area to obtain timber for riprap or 

equipment mats. 

Attempt to use no more than two (2) layers of timber riprap to support equipment on the 

construction right-of-way. 

Remove all Project-related material used to support equipment on the construction right-ofway upon completion of construction. 

Reference Figure 19-22 for wetland crossing details. 

8.2.3. "Dry" Wetland Crossing Method 

Topsoil shall be segregated. Pipe stringing and fabrication may occur within the wetland 

adjacent to the trench line or adjacent to the wetland in a designated extra workspace. The 

"dry" wetland crossing procedure depicted in Figure 19 shall be used where this type of 

wetland is identified on the Construction Drawings. The following are exceptions to 

"standard" wetland crossing methods: 

 The width of the construction right-of-way for upland construction is maintained through 

the wetland. 

 Sediment barriers are not required across or along the edges of the construction right-ofway. 

 If the wetland is cultivated, the topsoil shall be stripped using the trench and spoil side 

method at the same depth as the adjacent upland areas. 

 Seeding requirements for agricultural lands shall be applied to farmed wetlands. 

8.2.4. "Standard" Wetland Crossing Method 
Cameron Interstate Pipeline Expansion 

Environmental Plan 

Page 33 of 42

Topsoil stripping is impracticable due to the saturated nature of the soil. Pipe stringing and 

fabrication may occur within the wetland adjacent to the trench line or adjacent to the 

wetland in a designated extra workspace. Based upon the length of a standard wetland 

crossing and presence of sufficient water to float the pipe, the Contractor may elect to install 

a standard wetland crossing utilizing the “push/pull” method. The standard wetland crossing 

procedure depicted in Figure 20 shall be used where this type of wetland is identified on the 

Construction Drawings. 

 Procedures unique to standard wetlands include: 

 Limiting construction right-of-way width to a maximum of seventy-five (75) feet unless 

site conditions warrant a wider width or as specified in Appendix A. 

 Utilizing low ground pressure construction equipment or support equipment on timber rip 

rap or timber mats 

 Installing sediment barriers across the entire right-of-way where the right-of-way enters 

and exits the wetland 

8.2.5. Flooded "Push/Pull" Wetland Crossing Method

In these wetlands, standing surface water or high groundwater levels are present. Difficult 

trenching conditions may exist, and trench widths of up to thirty-five (35) feet are common. 

Topsoil stripping is impossible due to the flooded conditions. Pipe stringing and fabrication is 

required adjacent to the wetland in a designated extra workspace. And the pipe pushed 

and/or pulled with flotation into place. The "Push/Pull" Wetland crossing procedure as 

depicted in Figure 21 shall be used where water is sufficient to float the pipeline in the 

trench and other site conditions allow. Clean metal barrels or Styrofoam floats may be used 

to assist in the flotation of the pipe. Metal banding shall be used to secure the barrels or 

floats to the pipe. All barrels, floats and banding shall be recovered and removed upon 

completion of lower-in. Backfill shall not be allowed before recovery of barrels, floats and 

banding. 

8.2.6. Spoil Pile Placement and Control (Wetlands) 

All spoil from wetland or minor and intermediate waterbody crossings, and upland spoil from 

major waterbody crossings, must be placed in the construction right-of-way at least ten (10) 

feet from the water's edge or in additional extra work areas as needed. 

Use sediment barriers to prevent the flow of spoil or heavily silt-laden water into any 

wetland, waterbody or drainage feature. Should sediment migrate beyond sediment barriers 

steps shall be taken immediately to repair breaches in the barrier and to retrieve lost 

sediment. Should heavily silt-laden water seep from the barriers, immediate steps shall be 

taken to reduce flow and provide for adequate settling or filtration. 

Reference Figures 19-22 for placement of controls. 

8.2.7. Dewatering Activities (Wetlands) 

Trench dewatering shall occur as needed to prevent sediment laden water from entering 

wetlands, waterbodies or drainage channels that are beyond the immediate construction 

area. 

Trench water shall not be allowed to enter wetlands, waterbodies or drainage channels in 

such as way as to cause or contribute to scouring or sedimentation. 
Cameron Interstate Pipeline Expansion 

Environmental Plan 

Page 34 of 42

Dewatering structures shall be limited by the following conditions: 

a. constructed within well vegetated uplands areas where engineering and routing 

conditions permit 

b. placed at the farthest location above wetlands, waterbodies or drainage channels as is 

practical 

c. located above natural sediment barriers such as existing well vegetated earthen 

berms or above sediment barriers constructed with appropriate materials 

d. within wetlands shall be removed immediately after use 

e. constructed and maintained to ensure discharge water quality meets the applicable 

regulatory standards 

Contractor shall supply adequate pumping equipment, hoses and supplies to each 

dewatering location for appropriate placement and maintenance of dewatering activities. 

Dewatering intake hoses shall be floated near the surface of trench water to reduce uptake 

of concentrated sediments within the trench water. This shall increase efficiency of pumps 

and filtration bags and increase discharge water quality. 

Discharge water clarity shall be visually monitored during dewatering activities. Should 

discharge water appear to be cloudier than the receiving water or the water immediately 

upstream of dewatering location, or fail to meet the water quality requirements for any 

reason such as improper materials, placement, construction or maintenance of dewatering 

structures, dewatering activities shall cease immediately. Structures shall be moved, 

repaired, or replaced as requested by the Environmental Inspector. 

Reference Figures 16-18 for dewatering details. 

8.2.8. Filter Bags for Dewatering (Wetlands) 

Contractor shall supply and utilize filter bags, for purposes of dewatering, of the minimum 

specification as follows in the following table: 

Parameter Minimum Specification 

Grab Elongation @ Break 100% (max) 

Puncture Resistance > 100 lbs. 

Trapezoid Tear Strength > 75 lbs. 

Burst Strength > 350 psi 

Apparent Opening Size (AOS) 70 – 100 

(U.S. sieve no. equivalent) 

Water Flow Rate > 105 gpm/sq. ft. 

Contractor shall have the option to procure pre-fabricated filter bags or to construct them onsite with the above specified geotextile fabric. If on-site construction is utilized, Contractor 

shall construct the filter bag to provide efficient sediment removal and resist seam failure. 

Contractor shall monitor the condition of the filter bags throughout the dewatering activities 

and shall ensure appropriate pumping levels shall be used in accordance with 

manufacturers recommended filter bag capacity. 

Contractor shall remove used filter bags from the construction right-of-way immediately 

following dewatering activities.

Reference Figures 16 and 18 for filter bag diagram and details. 

8.2.9. Temporary Erosion and Sediment Control (Wetlands) 

Install sediment barriers prior to initial disturbance of the waterbody or adjacent upland. 

Sediment barriers must be properly maintained throughout construction and reinstalled as 

necessary (such as after backfilling of the trench) until replaced by permanent erosion 

controls or restoration of adjacent upland areas is complete. The following specific 

measures must be implemented at stream crossings: 

a. Install sediment barriers across the entire construction right-of-way at all waterbody 

crossings where necessary to prevent the flow of sediments into the waterbody. In 

the travel lane these may consist of removable sediment barriers or drivable berms. 

Removable sediment barriers can be removed during the construction day but must 

be re-installed after construction has stopped for the day and/or when heavy 

precipitation is anticipated; 

b. Where waterbodies are adjacent to the construction right-of-way, install sediment 

barriers along the edge of the construction right-of-way as necessary to contain spoil 

and sediment within the construction right-of-way; and 

c. Use trench plugs at all waterbody crossings, as necessary, to prevent diversion of 

water into upland portions of the pipeline trench and to keep any accumulated trench 

water out of the waterbody. 

Install temporary erosion controls immediately before initial disturbance of the soil where 

practical. Where dense existing vegetation is present, install temporary erosion controls 

immediately following initial disturbance. Maintain sediment barriers until replaced by 

permanent erosion controls or restoration of adjacent upland areas are complete. 

Install sediment barriers across the entire construction right-of-way at all wetland crossings 

where necessary to prevent sediment flow into the wetland. In the travel lane, these may 

consist of removable sediment barriers or drivable berms. Removable sediment barriers 

can be removed during the construction day, but must be re-installed after construction has 

stopped for the day and/or when heavy precipitation is anticipated. 

Where wetlands are adjacent to the construction right-of-way and the right-of-way slopes 

toward the wetland, install sediment barriers along the edge of the construction right-of-way 

as necessary to prevent sediment flow into the wetland. 

Install sediment barriers along the edge of the construction right-of-way as necessary to 

contain spoil and sediment within the wetland construction right-of-way. Remove these 

sediment barriers during initial right-of-way clean-up immediately following backfill 

operations. 

Reference Figures 6 and 7 for barrier details. 

8.3. Restoration (Wetlands) 

Where the pipeline trench may drain a wetland, construct trench breakers and/or seal the trench 

bottom as necessary to maintain the original wetland hydrology. 

Contractor shall ensure the appropriate replacement of subsoil and topsoil within the trench. 
Cameron Interstate Pipeline Expansion 

Environmental Plan 

Page 36 of 42

Contractor shall ensure pre-construction contours are met following restoration activities. No 

right-of-way of the trench shall be permitted within wetlands. 

For each wetland crossed, install a trench breaker at the base of slopes near the boundary 

between the wetland and adjacent upland areas. Install a permanent slope breaker across the 

construction right-of-way at the base of a slope greater than five percent (5%) where the base of 

the slope is less than fifty (50) feet from the wetland, or as needed to prevent sediment transport 

into the wetland. In addition, install sediment barriers as outlined. In some areas, with the 

approval of the Environmental Inspector, an earthen berm may be suitable as a sediment barrier 

adjacent to the wetland. 

Do not use fertilizer, lime, or mulch unless required in writing by the appropriate land 

management or state agency. 

Consult with the appropriate land management or state agency to develop a Project-specific 

wetland restoration plan. The restoration plan should include measures for re-establishing 

herbaceous and/or woody species, controlling the invasion and spread of undesirable exotic 

species (e.g., purple loosestrife and phragmites), and monitoring the success of the 

revegetation and weed control efforts. 

Until a Project-specific wetland restoration plan is developed and/or implemented, temporarily 

revegetate the construction right-of-way with annual rye grass at a rate of forty (40) pounds/acre 

(unless standing water is present). 

Ensure that all disturbed areas are successfully revegetated with wetland herbaceous and/or 

woody plant species. 

Remove temporary sediment barriers located at the boundary between wetland and adjacent 

upland areas after upland revegetation and stabilization of adjacent upland areas are verified by 

the Environmental Inspector to be successful as specified. 

Reference Figure 22 for backfill details. 

8.4. Post-Construction Maintenance (Wetland) 

Do not conduct vegetation maintenance over the full width of the permanent right-of-way in 

wetlands. However, to facilitate periodic pipeline corrosion/leak surveys, a corridor centered on 

the pipeline and up to ten (10) feet wide may be maintained in an herbaceous state. In addition, 

trees within fifteen (15) feet of the pipeline, which are greater than fifteen (15) feet in height, 

may be selectively cut and removed from the permanent right-of-way. 

Do not use herbicides or pesticides in or within one hundred (100) feet of a wetland, except as 

allowed by the appropriate land management agency or state agency. 

Wetland revegetation shall be considered successful if the cover of herbaceous and/or woody 

species is at least eighty percent (80%) of the type, density, and distribution of the vegetation in 

adjacent wetland areas that were not disturbed by construction. 

9. HYDROSTATIC TESTING 
Cameron Interstate Pipeline Expansion 

Environmental Plan 

Page 37 of 42

9.1. Testing Equipment Location 

The Contractor shall provide for the safety of all pipeline construction personnel and the general 

public during hydrostatic test operations by placing warning signs in populated areas. The 

Contractor shall locate hydrostatic test manifolds one hundred (100) feet outside wetlands and 

riparian areas to the maximum extent practicable. 

9.2. Test Water Source and Discharge Locations 

Company is responsible for acquiring all permits required by federal, state and local agencies 

for procurement of water and for the discharge of water used in the hydrostatic testing 

operation. Company shall provide the Contractor with a copy of the appropriate 

withdrawal/discharge permit for hydrostatic test water. The Contractor shall keep the water 

withdrawal/discharge permit on site at all times during testing operations. 

Any water obtained or discharged shall be in compliance with permit notice requirements and 

with sufficient notice for Company's Testing Inspector to make water sample arrangements prior 

to obtaining or discharging water. In some instances sufficient quantities of water may not be 

available from the permitted water sources at the time of testing. Withdrawal rates may be 

limited as stated by the permit. Under no circumstances shall an alternate water source be used 

without prior authorization from Company. The Contractor shall be responsible for obtaining any 

required water analyses from each source to be used in sufficient time to have a lab analysis 

performed prior to any filling operations. The sample bottle shall be sterilized prior to filling with 

the water sample. The analysis shall determine as specified in Appendix A. Each bottle shall be 

marked with: 

 Source of water with pipeline station number 

 Date taken 

 Laboratory order number 

 Name of person taking sample 

Staging/work areas for filling the pipeline with water shall be located a minimum of fifty (50) feet 

from the waterbody or a wetland boundary if topographic conditions permit. The Contractor shall 

install temporary sediment filter devices adjacent to all streams that runoff may enter. The 

Contractor shall screen the intake hose to prevent the entrainment of fish or debris. The hose 

shall be kept off the bottom of the waterbody. Refueling of construction equipment shall be 

conducted a minimum distance of one hundred (100) feet from the stream or a wetland. Pumps 

used for hydrostatic testing within one hundred (100) feet of any waterbody or wetland shall be 

operated and refueled in accordance with Section 3. The Contractor shall maintain adequate 

flow rates in the waterbody to protect aquatic life, provide for all waterbody uses, and provide for 

downstream withdrawals of water by existing users. The Contractor shall not use chemicals in 

the test water. The Contractor shall not discharge any water containing oil or other substances 

that are in sufficient amounts as to create a visible color film or sheen on the surface of the 

receiving water. Selected road, railroad, and river crossing pipe sections may be specified to be 

pre-tested for a minimum of four (4) hours. The water for pre-testing of any road and railroad 

crossings shall be hauled by a tanker truck from an approved water source. Water for pretesting of a river crossing may be hauled or taken from the respective river if it is an approved 

water source. Since the volume of water utilized in these pretests shall be relatively small, the 

water shall be discharged overland along the construction right-of-way and allowed to soak into 

the ground utilizing erosion and sediment control mitigative measures. Selection of final test 
Cameron Interstate Pipeline Expansion 

Environmental Plan 

Page 38 of 42

water sources will be determined based on site conditions at the time of construction and 

applicable permits. 

9.3. Dewatering the Pipeline 

 

The Contractor shall comply with state-issued NPDES permits for discharging test water. The 

Contractor shall not discharge any water containing oil or other substances that are in sufficient 

amounts as to create a visible color film on the surface of the receiving water. The Contractor 

shall not discharge into state-designated exceptional value waters, waterbodies which provide 

habitat for federally listed threatened or endangered species, or waterbodies designated as 

public water supplies, unless appropriate Federal, State, and local permitting agencies grant 

written permission. 

The Contractor shall calculate, record and provide to Company the day, date, time, location, 

total volume, maximum rate and methods of all water discharged to the ground or to surface 

water in association with hydrostatic testing. The Contractor shall regulate the pig velocity 

discharge rate, use an energy dissipation device(s), and install sediment barriers, as necessary, 

to prevent erosion, streambed scour, suspension of sediments, or excessive stream flow. Water 

must be disposed of using good engineering judgment so that all federal, state, and local 

environmental standards are met. Dewatering lines shall be sufficient strength and be securely 

supported and tied down at the discharge end to prevent whipping during this operation. 

To reduce the velocity of the discharge, The Contractor shall utilize an energy dissipating device 

described as follows: 

9.3.1. Splash Pup 

A splash pup consists of a piece of large diameter pipe (usually over twenty inches (20") 

O.D.) of variable length with both ends partially blocked that is welded perpendicularly to the 

discharge pipe. As the discharge hits against the inside wall of the pup, the velocity is 

rapidly reduced and the water is allowed to flow out either end. A variation of the splash pup 

concept, commonly called a diffuser, incorporates the same design, but with capped ends 

and numerous holes punched in the pup to diffuse the energy. 

9.3.2. Splash Plate 

The splash plate is a quarter section of thirty-six (36) inch pipe welded to a flat plate and 

attached to the end of a six (6) inch discharge pipe. The velocity is reduced by directing the 

discharge stream into the air as it exits the pipe. This device is also effective for most 

overland type discharge. 

 

9.3.3. Plastic Liner 

In areas where highly erodible soils exist or in any low flow drainage channel, it is a common 

practice to use layers of visqueen (or any of the new construction fabrics currently available) 

to line the receiving channel for a short distance. One anchoring method may consist of a 

small load of rocks to keep the fabric in place during the discharge. 

9.3.4. Straw Bale Dewatering Structure 

Straw bale dewatering structures are designed to dissipate and remove sediment from the 

water being discharged. Straw bale structures are used for on-land discharge of wash water 

and hydrostatic test water and in combination with other energy dissipating devices for high 

volume discharges. A straw bale dewatering structure is shown In Figure 23.

10. OFF-ROAD VEHICLE CONTROL 

Company shall offer to each owner or manager of forested lands to install and maintain measures to 

control unauthorized vehicle access to the right-of-way. These measures may include: 

 signs 

 fences with locking gates 

 slash and timber barriers, pipe barriers, or a line of boulders across the right-of-way 

 conifers or other appropriate trees or shrubs across the right-of-way 

 

11. SPILL PREVENTION AND CONTAINMENT 

Spill prevention and containment applies to the use and management of hazardous materials on the 

construction right-of-way and all ancillary areas during construction. This includes the refueling or 

servicing of all equipment with diesel fuel, gasoline, lubricating oils, grease, hydraulic and other fluids 

during normal upland applications and special applications within one hundred (100) feet of perennial 

streams or wetlands. All Vehicles and Equipment Must have a Spill Kit On Board. 

11.1. Spill Prevention 

11.1.1. Staging Areas 

Staging areas (including Contractor yards and pipe stockpile sites) shall be set up for each 

construction spread. Hazardous materials at staging areas shall be stored in compliance 

with federal and state laws. The following spill prevention measures shall be implemented 

by the Contractor: 

 Contractor fuel trucks shall be loaded at existing bulk fuel dealerships or from bulk tanks 

set up for that purpose at the staging area. In the former case, the bulk dealer is 

responsible for preventing and controlling spills; 

 Fuels and lubricants shall be stored only at designated staging areas. Storage of fuel 

and lubricants in the staging area shall be at least one hundred (100) feet away from the 

water's edge. 

 Refueling and lubrication of equipment shall be restricted to upland areas at least one 

hundred (100) feet away from stream channels and wetlands; 

 Contractors shall be required to perform all routine equipment maintenance at the 

staging area and recover and dispose of wastes in an appropriate manner; 

 Temporary liners and berms and/or dikes (secondary containment) shall be constructed 

around the above-ground bulk tanks, so that potential spill materials shall be contained 

and collected in specified areas isolated from any waterbodies. Tanks shall not be 

placed in areas subject to periodic flooding or washout; 

 Drivers of tank trucks are responsible for safety and spill prevention during tank truck 

unloading. Procedures for loading and unloading tank trucks shall meet the minimum 

requirements established by the Department of Transportation; 

 Warning signs requiring drivers to set brakes and chock wheels shall be displayed at all 

tanks. Proper grounding of equipment shall be undertaken during fuel transfer 

operations. Drivers shall observe and control the fueling operations at all times to 

prevent over-filling the temporary tank; 

 Prior to departure of any tank truck, all vehicle outlets shall be closely examined by the 

driver for leakage and tightened, adjusted or replaced to prevent liquid Ieakage while in 

transit; 
Cameron Interstate Pipeline Expansion 

Environmental Plan 

Page 40 of 42

 A supply of sorbent and barrier materials sufficient to allow the rapid containment and 

recovery of any spill shall be maintained at the construction staging areas. Sorbent and 

barrier materials shall also be utilized to contain runoff from contaminated areas; 

 Shovels and drums shall be kept at each of the individual staging areas. In the event that 

small quantities of soil become contaminated, shovels shall be utilized to collect the soil 

and the material shall be stored in fifty-five (55) gallon drums. Large quantities of 

contaminated soil may be bio-remediated on-site, subject to government approval, or 

collected utilizing heavy equipment, and stored in drums or other suitable containers 

prior to disposal. Should contamination occur adjacent to staging areas as a result of 

runoff, shovels and/or heavy equipment shall be utilized to collect the contaminated 

material. Contaminated soil shall be disposed of in accordance with state and federal 

regulations; 

 Temporary above-ground tanks shall be subject to visual inspection on a monthly basis 

and when the tank is refilled. Inspection records shall be maintained. Operators shall 

routinely keep tanks under close surveillance and potential leaks or spills shall be quickly 

detected; 

 Visible fuel leaks shall be reported to the Contractors' designated representative and 

corrected as soon as conditions warrant. Company's designated representative shall 

also be informed; 

 Drain valves on temporary tanks shall be locked to prevent accidental or unauthorized 

discharges from the tank. Company may allow modification of the above specifications 

as necessary to accommodate specific situations or procedures. Any modifications must 

comply with all applicable regulations and permits. 

11.1.2. Construction Right-of-way 

Rubber-tired vehicles (pick-up trucks, buses) shall normally refuel at the construction staging 

areas or commercial gas stations. Tracked machinery (backhoes, bulldozers) shall be 

refueled and lubricated on the construction right-of-way. Equipment maintenance shall be 

conducted in staging areas when practical. When impractical, repairs to equipment can be 

made on the construction right-of-way when approved by Company’s representative. The 

following preventive measures apply to refueling and lubricating activities on the 

construction right-of-way: 

 Construction activities shall be conducted to allow for prompt and effective clean up of 

spills of fuel and other hazardous materials. Each construction crew, including clean-up 

crews shall have on hand sufficient tools and material to stop leaks and supplies of 

absorbent and barrier materials to allow rapid containment and recovery of spilled 

materials and must know and follow the procedure for reporting spills; 

 Refueling and lubrication of construction equipment shall be restricted to upland areas at 

least one hundred (100) feet away from stream channels and wetlands. Where this is not 

possible (e.g., trench dewatering pumps), the equipment shall be fueled by designated 

personnel with special training in refueling and spill containment and clean up. The 

Environmental Inspector shall ensure that signs are installed identifying restricted areas; 

 Spent oils, lubricants, filters, etc. shall be collected and disposed of at an approved 

location in accordance with state and federal regulations; 

 Equipment shall not be washed in streams. Company may allow modification of the 

above specifications as necessary to accommodate specific situations or procedures. 

Any modifications must still comply with all applicable regulations and permits

11.2. Contingency Plans 

The Contractor shall develop emergency response procedures for all incidents (e.g., spills, 

leaks, fires) involving hazardous materials which could pose a threat to human health and/or the 

environment. The procedures shall address activities in all work areas, as well as during 

transport to and from the construction right-of-way and to any disposal or recycling facility. 

11.3. Equipment 

The Contractor shall retain emergency response equipment that shall be available at all areas 

where hazardous materials are handled or stored. This equipment shall be readily available to 

respond to a hazardous material emergency. Such equipment shall include, but not be limited 

to, the following: 

 first aid kit/supplies 

 phone or communications radio 

 protective clothing (Tyvek suit, gloves, goggles, boots) 

 hand held fire equipment

Fuel and service trucks shall carry a minimum of twenty (20) pounds of suitable commercial 

sorbent material. The Contractor shall inspect emergency equipment weekly, and service and 

maintain equipment regularly. Records shall be kept of all inspections and services. 

11.4. Emergency Notification 

Emergency notification procedures between the Contractor and Company shall be established 

in the preplanning stages of construction, and the Company representative shall be identified to 

serve as contact in the event of a spill during construction activities. In the event of a spill which 

meets government reporting criteria, the Contractor shall notify the Company representative 

immediately who, in turn, shall notify the appropriate regulatory agencies as documented in 

Appendix 1. 
Cameron Interstate Pipeline Expansion 

Environmental Plan 

Page 42 of 42

11.5. Spill Containment and Countermeasures 

 

In the event of a spill of hazardous material, Contractor personnel shall: 

 notify the appointed Company representative; 

 identify the product hazards related to the spilled material and implement appropriate 

safety procedures, based on the nature of the hazard; 

 control danger to the public and personnel at the site; 

 implement spill contingency plans and mobilize appropriate resources and manpower; 

 isolate or shutdown the source of the spill; 

 block manholes or culverts to limit spill travel; 

 initiate containment procedures to limit the spill to as small an area as possible, to 

prevent damage to property or areas of environment concern (e.g., watercourses); and 

 commence recovery of the spill and clean-up operations. 

When notified of a spill, the Company representative shall immediately ensure that: 

 action is taken to control danger to the public and personnel at the site; 

 spill contingency plans are implemented and that necessary equipment and manpower 

are mobilized; 

 measures are taken to isolate or shutdown the source of the spill; 

 all resources necessary to contain, recover and clean up the spill are available; 

 any resources requested by the Contractor from Company are provided; and 

 the appropriate agencies are notified. For spills which occur on public Iands, into surface 

waters or into sensitive areas the appropriate federal or state managing office shall also 

be notified and involved in the incident. On a land spill, berms shall be constructed with 

available equipment to physically contain the spill. Personnel entry and travel on 

contaminated soils shall be minimized. Sorbent materials shall be applied or, if 

necessary, heavily contaminated soils shall be removed to an approved facility. 

Contaminated sorbent materials and vegetation shall also be disposed of at an approved 

facility. On a spill threatening a water body, berms and/or trenches shall be constructed 

to contain the spill prior to entry into a water body. Deployment of booms, skimmers and 

sorbent materials shall be necessary if the spill reaches the water. The spilled product 

shall be recovered and the contaminated area shall be cleaned up with in consultation

PLAN AND PROCEDURES ADDRESSING UNANTICIPATED DISCOVERY OF 

CULTURAL RESOURCES AND HUMAN REMAINS 

I. INTRODUCTION 

This document outlines the procedures Cameron Interstate Pipeline (Cameron Interstate) will 

follow to prepare for and address any unanticipated discovery. It provides direction to Cameron 

Interstate personnel and their consultants as to the proper procedure to follow in the event that 

unanticipated discovery of historic properties or human remains are made during construction. 

Communications, transmittals, reports, etc. may be provided via e-mail to the addresses 

provided in the contact lists in this document. 

II. TRAINING AND ORIENTATION 

The Environmental Inspector (EI) will be responsible for advising construction contractor 

personnel on the procedures to follow in the event that an unanticipated discovery is made. 

Training will occur as part of the pre-construction on-site training program for foremen, company 

inspectors, and construction supervisors. The EI will advise all operators of equipment involved 

in grading, stripping, or trenching activities to: 

A. Stop work immediately if they observe any indication of the presence of cultural 

materials (artifacts or other man-made features), animal bone, or possibly human 

bone. 

B. Contact the EI (or the Chief Inspector if the EI is not available) as soon as possible. 

C. Comply with unanticipated discovery procedures. 

D. Treat human remains with dignity and respect. 

III. PROCEDURE WHEN CULTURAL MATERIALS ARE OBSERVED 

Cultural materials include man-made objects (prehistoric, historic, and greater than 50 years of 

age) and features (e.g., walls constructed of natural materials such as cobbles; surfaces paved 

by cobbles, brick or other material; or other remnants of cultural activity). 

A. Stop work in the immediate vicinity of the observed cultural materials 

1. Notify the EI of the discovery. 

2. If EI believes that an unanticipated discovery has been made: 

a) EI directs all ground-disturbing activities within 25 feet of the area of the discovery to 

stop. 

b) EI will protect and secure the evidence in place by delineating the find with flagging 

or orange safety fencing around the perimeter of the area within which construction 

activity will be prohibited. 

B. Minimize movement of vehicles (limit the passage of equipment to only those 

essential to continue working at the construction site) and equipment in area 

immediately surrounding the discovery.

J. If human remains are present in an aboriginal archeological context, Cameron 

Interstate will follow the procedures described in Section III E through J, except as 

follows: 

1. Notifications to FERC and Louisiana SHPO will make special note that human remains 

have been found. 

2. Cameron Interstate will notify appropriate Native American tribal groups, and request 

that identified Native American representatives advise Cameron Interstate, FERC, and 

Louisiana SHPO of any special desires they have regarding the disposition of the human 

remains. 

3. Proposals for site evaluation will give special consideration to the fact that human 

remains are present. 

a) No conduct of intrusive examination of the immediate area of the remains prior to 

receipt of a permit from the UBSB. 

b) Evaluate the potential for the presence of multiple graves and describe procedures 

for determining if other unidentified graves may be present. 

c) Describe efforts made to contact Native American tribes, the results of contacts, and 

efforts (as feasible) to accommodate the desires of the Native American tribes 

regarding the treatment of human remains. 

d) If the discovery was made after pipeline trenching in the vicinity of the discovery has 

been completed, construction will be permitted to recommence, except within 100 

feet of any human remains. 

e) Construction within the 100-foot area of the find will be permitted to proceed when 

the remains have been removed (or when it has been determined that the remains 

should be left in place). 

4. If FERC or the Louisiana SHPO advises Cameron Interstate that specific Native 

American tribal representatives wish to take custody of any human remains and rebury 

them on non-tribal lands, Cameron Interstate will, if requested, assist in any negotiations 

between the tribe and the landowner that may be necessary. 

5. Cameron Interstate will make a good faith effort to accommodate any requests from 

identified Native American tribal groups that they be present during the implementation 

of mitigation measures related to human remains. Subject to agreements with identified 

Native American tribal groups, Cameron Interstate will offer to compensate a single tribal 

representative for time spent observing or participating in the removal of Native 

American human remains. Compensation will include the individual’s time (at an hourly 

rate equivalent to that paid the professional archeologist) and associated travel and 

living expenses. 

K. If human remains are present in a non-aboriginal archeological context, the 

procedures described in Section IV E through J, will be followed except that:

1. Proposals for site evaluation will give special consideration to the fact that human 

remains are present (i.e., no intrusive examination of the immediate area of the remains; 

proposals will include an evaluation of the potential for the presence of multiple graves, 

and describe procedures for determining if other unidentified graves may be present). 

2. If it is determined by FERC, in consultation with Louisiana SHPO, that the associated 

archeological site is not eligible for the National Register of Historic Places and that no 

mitigation measures are necessary, the respective sheriff’s office will be requested to 

coordinate with the local coroner and either direct the archeologist to implement an 

approved plan for removal of the remains or arrange for alternative, appropriate removal 

of the human remains. 

3. Unless directed to do otherwise by FERC, Cameron Interstate will assume that it is 

authorized to resume construction when the remains have been removed. 

4. Within 15 business days of the resumption of construction, Cameron Interstate will 

provide FERC with a written report describing the removal activities. 

5. Proposals for mitigation will include discussion of what steps will be taken to attempt to 

identify lineal descendants of the deceased. 

6. If the discovery was made after trenching in the vicinity of the discovery has been 

completed, construction will be permitted to recommence, except within 100 feet of any 

human remains. 

7. Construction within the remaining 100-foot area of the find will be permitted to proceed 

when the remains have been removed (or when it has been determined that the remains 

should be left in place).

UPLAND EROSION CONTROL, REVEGETATION, 

AND MAINTENANCE PLAN (PLAN)

Note: Cameron Interstate Pipeline will adopt the FERC Plan as written for the Pipeline 

Project. 

I. APPLICABILITY 

A. The intent of this Plan is to assist applicants by identifying baseline 

mitigation measures for minimizing erosion and enhancing revegetation. 

The project sponsors should specify in their applications for a FERC 

Certificate (Certificate) any individual measures in this Plan they consider 

unnecessary, technically infeasible, or unsuitable due to local conditions 

and to fully describe any alternative measures they would use. Applicants 

should also explain how those alternative measures would achieve a 

comparable level of mitigation. 

Once a project is certificated, further changes can be approved. Any such 

changes from the measures in this Plan (or the applicant’s approved plan) 

will be approved by the Director of the Office of Energy Projects (Director), 

upon the applicant’s written request, if the Director agrees that an 

alternative measure: 

1. provides equal or better environmental protection; 

2. is necessary because a portion of this Plan is infeasible or 

unworkable based on project-specific conditions; or 

3. is specifically required in writing by another Federal, state, or Native 

American land management agency for the portion of the project on 

its land or under its jurisdiction. 

Any requirements in this Plan to file material with the Secretary of the 

FERC (Secretary) do not apply to projects undertaken under the 

provisions of the blanket certificate program. This exemption does not 

apply to a request for alternative measures. 

Project-related impacts on wetland and waterbody systems are addressed 

in the staff’s Wetland and Waterbody Construction and Mitigation 

Procedures (Procedures).

II. SUPERVISION AND INSPECTION 

A. ENVIRONMENTAL INSPECTION 

1. At least one Environmental Inspector is required for each 

construction spread during construction and restoration (as defined 

by section V). The number and experience of Environmental 

Inspectors assigned to each construction spread should be 

appropriate for the length of the construction spread and the 

number/significance of resources affected. 

2. Environmental Inspectors shall have peer status with all other 

activity inspectors. 

3. Environmental Inspectors shall have the authority to stop activities 

that violate the environmental conditions of the Certificate, state 

and Federal environmental permit conditions, or landowner 

requirements; and to order appropriate corrective action. 

B. RESPONSIBILITIES OF ENVIRONMENTAL INSPECTORS 

At a minimum, the Environmental Inspector(s) shall be responsible for: 

1. Ensuring compliance with the requirements of this Plan, the 

Procedures, the environmental conditions of the Certificate 

authorization, the mitigation measures proposed by the applicant 

(as approved and/or modified by the Certificate), other 

environmental permits and approvals, and environmental 

requirements in landowner easement agreements. 

2. Identifying, documenting, and overseeing corrective actions, as 

necessary to bring an activity back into compliance; 

3. Verifying that the limits of authorized construction work areas and 

locations of access roads are properly marked before clearing; 

4. Verifying the location of signs and highly visible flagging marking 

the boundaries of sensitive resource areas, waterbodies, wetlands, 
 PROJECT-SPECIFIC PLAN 

 Cameron Interstate Pipeline Environmental Plan 

 Cameron Pipeline Expansion Project 

 Docket No. CP13-___-000 

December 2012 

3 01/17/2003 VERSION 

or areas with special requirements along the construction work 

area; 

5. Identifying erosion/sediment control and soil stabilization needs in 

all areas; 

6. Ensuring that the location of dewatering structures and slope 

breakers will not direct water into known cultural resources sites or 

locations of sensitive species; 

7. Verifying that trench dewatering activities do not result in the 

deposition of sand, silt, and/or sediment near the point of discharge 

into a wetland or waterbody. If such deposition is occurring, the 

dewatering activity shall be stopped and the design of the 

discharge shall be changed to prevent reoccurrence; 

8. Ensuring that subsoil and topsoil are tested in agricultural and 

residential areas to measure compaction and determine the need 

for corrective action; 

9. Advising the Chief Construction Inspector when conditions (such as 

wet weather) make it advisable to restrict construction activities to 

avoid excessive rutting; 

10. Ensuring restoration of contours and topsoil; 

11. Verifying that the soils imported for agricultural or residential use 

have been certified as free of noxious weeds and soil pests, unless 

otherwise approved by the landowner; 

12. Determining the need for and ensuring that erosion controls are 

properly installed, as necessary to prevent sediment flow into 

wetlands, waterbodies, sensitive areas, and onto roads; 

13. Inspecting and ensuring the maintenance of temporary erosion 

control measures at least: 

a. on a daily basis in areas of active construction or equipment 

operation; 
 PROJECT-SPECIFIC PLAN 

 Cameron Interstate Pipeline Environmental Plan 

 Cameron Pipeline Expansion Project 

 Docket No. CP13-___-000 

December 2012 

4 01/17/2003 VERSION 

b. on a weekly basis in areas with no construction or equipment 

operation; and 

c. within 24 hours of each 0.5 inch of rainfall; 

14. Ensuring the repair of all ineffective temporary erosion control 

measures within 24 hours of identification; 

15. Keeping records of compliance with the environmental conditions of 

the FERC certificate, and the mitigation measures proposed by the 

project sponsor in the application submitted to the FERC, and other 

Federal or state environmental permits during active construction 

and restoration; and 

16. Identifying areas that should be given special attention to ensure 

stabilization and restoration after the construction phase. 

III. PRECONSTRUCTION PLANNING 

The project sponsor shall do the following before construction: 

A. CONSTRUCTION WORK AREAS 

1. Identify all construction work areas (e.g., construction right-of-way, 

extra work space areas, pipe storage and contractor yards, borrow 

and disposal areas, access roads, etc.) that would be needed for 

safe construction. The project sponsor must ensure that 

appropriate cultural resources and biological surveys have been 

conducted. 

2. Project sponsors are encouraged to consider expanding any 

required cultural resources and endangered species surveys in 

anticipation of the need for activities outside of certificated work 

areas. 

B. DRAIN TILE AND IRRIGATION SYSTEMS 

1. Attempt to locate existing drain tiles and irrigation systems. 
 PROJECT-SPECIFIC PLAN 

 Cameron Interstate Pipeline Environmental Plan 

 Cameron Pipeline Expansion Project 

 Docket No. CP13-___-000 

December 2012 

5 01/17/2003 VERSION 

2. Contact landowners and local soil conservation authorities to 

determine the locations of future drain tiles that are likely to be 

installed within 3 years of the authorized construction. 

3. Develop procedures for constructing through drain-tiled areas, 

maintaining irrigation systems during construction, and repairing 

drain tiles and irrigation systems after construction. 

4. Engage qualified drain tile specialists, as needed to conduct or 

monitor repairs to drain tile systems affected by construction. Use 

drain tile specialists from the project area, if available. 

C. GRAZING DEFERMENT 

Develop grazing deferment plans with willing landowners, grazing 

permittees, and land management agencies to minimize grazing 

disturbance of revegetation efforts. 

D. ROAD CROSSINGS AND ACCESS POINTS 

Plan for safe and accessible conditions at all roadway crossings and 

access points during construction and restoration. 

E. DISPOSAL PLANNING 

Determine methods and locations for the disposal of construction debris 

(e.g., timber, slash, mats, garbage, drilling fluids, excess rock, etc). Offsite disposal in other than commercially operated disposal locations is 

subject to compliance with all applicable survey, landowner permission, 

and mitigation requirements. 

F. AGENCY COORDINATION 

The project sponsor must coordinate with the appropriate local, state, and 

Federal agencies as outlined in this Plan and in the Certificate. 

1. Obtain written recommendations from the local soil conservation 

authorities or land management agencies regarding permanent 

erosion control and revegetation specifications. 
 PROJECT-SPECIFIC PLAN 

 Cameron Interstate Pipeline Environmental Plan 

 Cameron Pipeline Expansion Project 

 Docket No. CP13-___-000 

December 2012 

6 01/17/2003 VERSION 

2. Develop specific procedures in coordination with the appropriate 

agency to prevent the introduction or spread of noxious weeds and 

soil pests resulting from construction and restoration activities. 

G. STORMWATER POLLUTION PREVENTION PLAN 

Make available on each construction spread the Stormwater Pollution 

Prevention Plan prepared for compliance with the U.S. Environmental 

Protection Agency's National Stormwater Program General Permit 

requirements. 

IV. INSTALLATION 

A. APPROVED AREAS OF DISTURBANCE 

1. Project-related ground disturbance shall be limited to the 

construction right-of-way, extra work space areas, pipe storage 

yards, borrow and disposal areas, access roads, and other areas 

approved in the Certificate. Any project-related ground disturbing 

activities outside these Certificated areas, except those needed to 

comply with the Plan and Procedures (e.g., slope breakers, energydissipating devices, dewatering structures, drain tile system repairs) 

will require prior Director approval. All construction or restoration 

activities outside of the Certificated areas are subject to all 

applicable survey and mitigation requirements. 

2. The construction right-of-way width for a project shall not exceed 75 

feet or that described in the FERC application unless otherwise 

modified by a Certificate condition. However, in limited, nonwetland areas, this construction right-of-way width may be 

expanded by up to 25 feet without Director approval to 

accommodate full construction right-of-way topsoil segregation and 

to ensure safe construction where topographic conditions (such as 

side-slopes) or soil limitations require it. Twenty-five feet of extra 

construction right-of-way width may also be used in limited, nonwetland or non-forested areas for truck turn-arounds where no 

reasonable alternative access exists. 

Project use of these additional limited areas is subject to landowner 

approval and compliance with all applicable survey and mitigation 
 PROJECT-SPECIFIC PLAN 

 Cameron Interstate Pipeline Environmental Plan 

 Cameron Pipeline Expansion Project 

 Docket No. CP13-___-000 

December 2012 

7 01/17/2003 VERSION 

requirements. When such additional areas are used, each one 

should be identified and the need explained in the weekly or 

biweekly construction reports to the FERC, if required. The 

following material should be included in the reports: 

a. the location of each additional area by station number and 

reference to a previously filed alignment sheet, or updated 

alignment sheets showing the additional areas; 

b. identification of where the Commission's records contain 

evidence that the additional areas were previously surveyed; 

and 

c. a statement that landowner approval has been obtained and 

is available in project files. 

Prior written approval of the Director is required when the 

Certificated construction right-of-way width would be expanded by 

more than 25 feet. 

B. TOPSOIL SEGREGATION 

1. Unless the landowner or land management agency specifically 

approves otherwise, prevent the mixing of topsoil with subsoil by 

stripping topsoil from either the full work area or from the trench 

and subsoil storage area (ditch plus spoil side method) in: 

a. actively cultivated or rotated croplands and pastures ; 

b. residential areas; 

c. hayfields; and 

d. other areas at the landowner's or land managing agency’s 

request. 

2. In residential areas importation of topsoil is an acceptable 

alternative to topsoil segregation. 
 PROJECT-SPECIFIC PLAN 

 Cameron Interstate Pipeline Environmental Plan 

 Cameron Pipeline Expansion Project 

 Docket No. CP13-___-000 

December 2012 

8 01/17/2003 VERSION 

3. In deep soils (more than 12 inches of topsoil), segregate at least 12 

inches of topsoil. In soils with less than 12 inches of topsoil make 

every effort to segregate the entire topsoil layer. 

4. Where topsoil segregation is required, maintain separation of 

salvaged topsoil and subsoil throughout all construction activities. 

5. Segregated topsoil may not be used for padding the pipe. 

C. DRAIN TILES 

1. Mark locations of drain tiles damaged during construction. 

2. Probe all drainage tile systems within the area of disturbance to 

check for damage. 

3. Repair damaged drain tiles to their original or better condition. Do 

not use filter-covered drain tiles unless the local soil conservation 

authorities and the landowner agree. Use qualified specialists for 

testing and repairs. 

4. For new pipelines in areas where drain tiles exist or are planned, 

ensure that the depth of cover over the pipeline is sufficient to avoid 

interference with drain tile systems. For adjacent pipeline loops in 

agricultural areas, install the new pipeline with at least the same 

depth of cover as the existing pipeline(s). 

D. IRRIGATION 

Maintain water flow in crop irrigation systems, unless shutoff is 

coordinated with affected parties. 

E. ROAD CROSSINGS AND ACCESS POINTS 

1. Maintain safe and accessible conditions at all road crossings and 

access points during construction. 

2. If crushed stone access pads are used in residential or active 

agricultural areas, place the stone on synthetic fabric to facilitate 

removal.

December 2012 

9 01/17/2003 VERSION 

F. TEMPORARY EROSION CONTROL 

Install temporary erosion controls immediately after initial disturbance of 

the soil. Temporary erosion controls must be properly maintained 

throughout construction (on a daily basis) and reinstalled as necessary 

(such as after backfilling of the trench) until replaced by permanent 

erosion controls or restoration is complete. 

1. Temporary Slope Breakers 

a. Temporary slope breakers are intended to reduce runoff 

velocity and divert water off the construction right-of-way. 

Temporary slope breakers may be constructed of materials 

such as soil, silt fence, staked hay or straw bales, or sand 

bags. 

b. Install temporary slope breakers on all disturbed areas, as 

necessary to avoid excessive erosion. Temporary slope 

breakers must be installed on slopes greater than 5 percent 

where the base of the slope is less than 50 feet from 

waterbody, wetland, and road crossings at the following 

spacing (closer spacing should be used if necessary): 

 Slope (%) Spacing (feet) 

 5 - 15 300 

 >15 - 30 200 

 >30 100 

c. Direct the outfall of each temporary slope breaker to a stable, 

well vegetated area or construct an energy-dissipating 

device at the end of the slope breaker and off the 

construction right-of-way. 

d. Position the outfall of each temporary slope breaker to 

prevent sediment discharge into wetlands, waterbodies, or 

other sensitive resources.

 Docket No. CP13-___-000 

December 2012 

10 01/17/2003 VERSION 

2. Sediment Barriers 

a. Sediment barriers are intended to stop the flow of sediments 

and to prevent the deposition of sediments into sensitive 

resources. They may be constructed of materials such as 

silt fence, staked hay or straw bales, compacted earth (e.g., 

driveable berms across travelways), sand bags, or other 

appropriate materials. 

b. At a minimum, install and maintain temporary sediment 

barriers across the entire construction right-of-way at the 

base of slopes greater than 5 percent where the base of the 

slope is less than 50 feet from a waterbody, wetland, or road 

crossing until revegetation is successful as defined in this 

Plan. Leave adequate room between the base of the slope 

and the sediment barrier to accommodate ponding of water 

and sediment deposition. 

c. Where wetlands or waterbodies are adjacent to and 

downslope of construction work areas, install sediment 

barriers along the edge of these areas, as necessary to 

prevent sediment flow into the wetland or waterbody. 

3. Mulch 

a. Apply mulch on all slopes (except in actively cultivated 

cropland) concurrent with or immediately after seeding, 

where necessary to stabilize the soil surface and to reduce 

wind and water erosion. Spread mulch uniformly over the 

area to cover at least 75 percent of the ground surface at a 

rate of 2 tons/acre of straw or its equivalent, unless the local 

soil conservation authority, landowner, or land managing 

agency approves otherwise in writing. 

b. Mulch can consist of weed-free straw or hay, wood fiber 

hydromulch, erosion control fabric, or some functional 

equivalent. 

c. Mulch before seeding if: 
 PROJECT-SPECIFIC PLAN 

 Cameron Interstate Pipeline Environmental Plan

11 01/17/2003 VERSION 

(1) final grading and installation of permanent erosion 

control measures, will not be completed in an area 

within 20 days after the trench in that area is backfilled 

(10 days in residential areas), as required in 

section V.A.1; or 

(2) construction or restoration activity is interrupted for 

extended periods, such as when seeding cannot be 

completed due to seeding period restrictions. 

d. If mulching before seeding, increase mulch application on all 

slopes within 100 feet of waterbodies and wetlands to a rate 

of 3 tons/acre of straw or equivalent. 

e. If wood chips are used as mulch, do not use more than 

1 ton/acre and add the equivalent of 11 lbs/acre available 

nitrogen (at least 50 percent of which is slow release). 

f. Ensure that mulch is adequately anchored to minimize loss 

due to wind and water. 

g. When anchoring with liquid mulch binders, use rates 

recommended by the manufacturer. Do not use liquid mulch 

binders within 100 feet of wetlands or waterbodies. 

h. Install erosion control fabric on waterbody banks at the time 

of final bank recontouring. Anchor the erosion control fabric 

with staples or other appropriate devices. 

V. RESTORATION 

A. CLEANUP 

1. Commence cleanup operations immediately following backfill 

operations. Complete final grading, topsoil replacement, and 

installation of permanent erosion control structures within 20 days 

after backfilling the trench (10 days in residential areas). If 

seasonal or other weather conditions prevent compliance with these 

time frames, maintain temporary erosion controls (temporary slope

breakers and sediment barriers) until conditions allow completion of 

cleanup. 

The project sponsor should file with the Secretary for the review 

and written approval of the Director, a winterization plan if 

construction will continue into the winter season when conditions 

could delay successful decompaction, topsoil replacement, or 

seeding until the following spring. 

2. A travel lane may be left open temporarily to allow access by 

construction traffic if the temporary erosion control structures are 

installed as specified in section IV.F and inspected and maintained 

as specified in sections II.B.12 through 14. When access is no 

longer required the travel lane must be removed and the right-ofway restored. 

3. Rock excavated from the trench may be used to backfill the trench 

only to the top of the existing bedrock profile. Rock that is not 

returned to the trench should be considered construction debris, 

unless approved for use as mulch or for some other use on the 

construction work areas by the landowner or land managing 

agency. 

4. Remove excess rock from at least the top 12 inches of soil in all 

actively cultivated or rotated cropland and pastures, hayfields, and 

residential areas, as well as other areas at the landowner's request. 

The size, density, and distribution of rock on the construction work 

area should be similar to adjacent areas not disturbed by 

construction. The landowner may approve other provisions in 

writing. 

5. Grade the construction right-of-way to restore pre-construction 

contours and leave the soil in the proper condition for planting. 

6. Remove construction debris from all construction work areas unless 

the landowner or land managing agency approves otherwise. 

7. Remove temporary sediment barriers when replaced by permanent 

erosion control measures or when revegetation is successful.

B. PERMANENT EROSION CONTROL DEVICES 

1. Trench Breakers 

a. Trench breakers are intended to slow the flow of subsurface 

water along the trench. Trench breakers may be constructed 

of materials such as sand bags or polyurethane foam. Do 

not use topsoil in trench breakers. 

b. An engineer or similarly qualified professional shall 

determine the need for and spacing of trench breakers. 

Otherwise, trench breakers shall be installed at the same 

spacing as and upslope of permanent slope breakers. 

c. In agricultural fields and residential areas where slope 

breakers are not typically required, install trench breakers at 

the same spacing as if permanent slope breakers were 

required. 

d. At a minimum, install a trench breaker at the base of slopes 

greater than 5 percent where the base of the slope is less 

than 50 feet from a waterbody or wetland and where needed 

to avoid draining a waterbody or wetland. 

2. Permanent Slope Breakers 

a. Permanent slope breakers are intended to reduce runoff 

velocity, divert water off the construction right-of-way, and 

prevent sediment deposition into sensitive resources. 

Permanent slope breakers may be constructed of materials 

such as soil, sand bags, or some functional equivalent. 

b. Construct and maintain permanent slope breakers in all 

areas, except cultivated areas and lawns, using spacing 

recommendations obtained from the local soil conservation 

authority or land managing agency. 

In the absence of written recommendations, use the 

following spacing unless closer spacing is necessary to avoid 

excessive erosion on the construction right-of-way:

c. Construct slope breakers to divert surface flow to a stable 

area without causing water to pool or erode behind the 

breaker. In the absence of a stable area, construct 

appropriate energy-dissipating devices at the end of the 

breaker. 

d. Slope breakers may extend slightly (about 4 feet) beyond the 

edge of the construction right-of-way to effectively drain 

water off the disturbed area. Where slope breakers extend 

beyond the edge of the construction right-of-way, they are 

subject to compliance with all applicable survey 

requirements. 

C. SOIL COMPACTION MITIGATION 

1. Test topsoil and subsoil for compaction at regular intervals in 

agricultural and residential areas disturbed by construction 

activities. Conduct tests on the same soil type under similar 

moisture conditions in undisturbed areas to approximate 

preconstruction conditions. Use penetrometers or other appropriate 

devices to conduct tests. 

2. Plow severely compacted agricultural areas with a paraplow or 

other deep tillage implement. In areas where topsoil has been 

segregated, plow the subsoil before replacing the segregated 

topsoil. 

Alternatively, make arrangements with the landowner to plant and 

plow under a "green manure" crop, such as alfalfa, to decrease soil 

bulk density and improve soil structure. If subsequent construction 

and cleanup activities result in further compaction, conduct 

additional tilling.

December 2012 

15 01/17/2003 VERSION 

3. Perform appropriate soil compaction mitigation in severely 

compacted residential areas. 

D. REVEGETATION 

1. General 

a. The project sponsor is responsible for ensuring successful 

revegetation of soils disturbed by project-related activities, 

except as noted in section V.D.1.b. 

b. Restore all turf, ornamental shrubs, and specialized 

landscaping in accordance with the landowner's request, or 

compensate the landowner. Restoration work must be 

performed by personnel familiar with local horticultural and 

turf establishment practices. 

2. Soil Additives 

Fertilize and add soil pH modifiers in accordance with written 

recommendations obtained from the local soil conservation 

authority, land management agencies, or landowner. Incorporate 

recommended soil pH modifier and fertilizer into the top 2 inches of 

soil as soon as possible after application. 

3. Seeding Requirements 

a. Prepare a seedbed in disturbed areas to a depth of 3 to 4 

inches using appropriate equipment to provide a firm 

seedbed. When hydroseeding, scarify the seedbed to 

facilitate lodging and germination of seed. 

b. Seed disturbed areas in accordance with written 

recommendations for seed mixes, rates, and dates obtained 

from the local soil conservation authority or the request of the 

landowner or land management agency. Seeding is not 

required in actively cultivated croplands unless requested by 

the landowner. 
 PROJECT-SPECIFIC PLAN 

 Cameron Interstate Pipeline Environmental Plan 

 Cameron Pipeline Expansion Project 

 Docket No. CP13-___-000 

December 2012 

16 01/17/2003 VERSION 

c. Perform seeding of permanent vegetation within the 

recommended seeding dates. If seeding cannot be done 

within those dates, use appropriate temporary erosion 

control measures discussed in section IV.F. and perform 

seeding of permanent vegetation at the beginning of the next 

recommended seeding season. Lawns may be seeded on a 

schedule established with the landowner. 

d. In the absence of written recommendations from the local 

soil conservation authorities, seed all disturbed soils within 6 

working days of final grading, weather and soil conditions 

permitting, subject to the specifications in section V.D.3.a-c. 

e. Base seeding rates on Pure Live Seed. Use seed within 12 

months of seed testing. 

f. Treat legume seed with an inoculant specific to the species 

using the manufacturer’s recommended rate of inoculant 

appropriate for the seeding method (broadcast, drill, or 

hydro). 

g. In the absence of written recommendations from the local 

soil conservation authorities, landowner, or land managing 

agency to the contrary, a seed drill equipped with a 

cultipacker is preferred for seed application. 

Broadcast or hydroseeding can be used in lieu of drilling at 

double the recommended seeding rates. Where seed is 

broadcast, firm the seedbed with a cultipacker or roller after 

seeding. In rocky soils or where site conditions may limit the 

effectiveness of this equipment, other alternatives may be 

appropriate (e.g., use of a chain drag) to lightly cover seed 

after application, as approved by the Environmental 

Inspector. 

VI. OFF-ROAD VEHICLE CONTROL 

To each owner or manager of forested lands offer to install and maintain 

measures to control unauthorized vehicle access to the right-of-way. These 

measures may include:

 Docket No. CP13-___-000 

December 2012 

17 01/17/2003 VERSION 

A. Signs; 

B. Fences with locking gates; 

C. Slash and timber barriers, pipe barriers, or a line of boulders across the 

right-of-way; and 

D. Conifers or other appropriate trees or shrubs across the right-of-way. 

VII. POST-CONSTRUCTION ACTIVITIES 

A. MONITORING AND MAINTENANCE 

1. Conduct follow-up inspections of all disturbed areas after the first 

and second growing seasons to determine the success of 

revegetation. 

2. Revegetation in non-agricultural areas shall be considered 

successful if upon visual survey the density and cover of nonnuisance vegetation are similar in density and cover to adjacent 

undisturbed lands. In agricultural areas, revegetation shall be 

considered successful if crop yields are similar to adjacent 

undisturbed portions of the same field. 

Continue revegetation efforts until revegetation is successful. 

3. Monitor and correct problems with drainage and irrigation systems 

resulting from pipeline construction in active agricultural areas until 

restoration is successful. 

4. Restoration shall be considered successful if the right-of-way 

surface condition is similar to adjacent undisturbed lands, 

construction debris is removed (unless requested otherwise by the 

land owner or land managing agency), revegetation is successful, 

and proper drainage has been restored. 

5. Routine vegetation maintenance clearing shall not be done more 

frequently than every 3 years. However, to facilitate periodic 

corrosion and leak surveys, a corridor not exceeding 10 feet in 
 PROJECT-SPECIFIC PLAN

width centered on the pipeline may be maintained annually in a 

herbaceous state. In no case shall routine vegetation maintenance 

clearing occur between April 15 and August 1 of any year. 

6. Efforts to control unauthorized off-road vehicle use, in cooperation 

with the landowner, shall continue throughout the life of the project. 

Maintain signs, gates, and vehicle trails as necessary. 

B. REPORTING 

1. The project sponsor shall maintain records that identify by milepost: 

a. method of application, application rate, and type of fertilizer, 

pH modifying agent, seed, and mulch used; 

b. acreage treated; 

c. dates of backfilling and seeding; 

d. names of landowners requesting special seeding treatment 

and a description of the follow-up actions; and 

e. any problem areas and how they were addressed. 

2. The project sponsor shall file with the Secretary quarterly activity 

reports documenting problems, including those identified by the 

landowner, and corrective actions taken for at least 2 years 

following construction.

WETLAND AND WATERBODY CONSTRUCTION AND MITIGATION PROCEDURES 

(PROCEDURES)

Note: Text boxes have been inserted into this document to identify specific areas where 

Cameron Interstate has proposed construction methods, mitigation measures, and/or 

deviations from the FERC Procedures 

I. APPLICABILITY 

A. The intent of these Procedures is to assist applicants by identifying 

baseline mitigation measures for minimizing the extent and duration of 

project-related disturbance on wetlands and waterbodies. The project 

sponsors should specify in their applications for a FERC Certificate 

(Certificate) any individual measures in these Procedures they consider 

unnecessary, technically infeasible, or unsuitable due to local conditions 

and to fully describe any alternative measures they would use. Applicants 

should also explain how those alternative measures would achieve a 

comparable level of mitigation. 

Once a project is certificated, further changes can be approved. Any such 

changes from the measures in these Procedures (or the applicant’s 

approved procedures) will be approved by the Director of the Office of 

Energy Projects (Director), upon the applicant’s written request, if the 

Director agrees that an alternative measure: 

1. provides equal or better environmental protection; 

2. is necessary because a portion of these Procedures is infeasible or 

unworkable based on project-specific conditions; or 

3. is specifically required in writing by another Federal, state, or Native 

American land management agency for the portion of the project on 

its land or under its jurisdiction. 

Any requirements in these Procedures to file material with the Secretary of 

the FERC (Secretary) do not apply to projects undertaken under the 

provisions of the blanket certificate program. This exemption does not 

apply to a request for alternative measures. 
 PROJECT-SPECIFIC PROCEDURES 

 Cameron Interstate Pipeline Environmental Plan 

 Cameron Pipeline Expansion Project 

 Docket No. CP13-___-000 

December 2012 

2 01/17/2003 VERSION

Project-related impacts on non-wetland areas are addressed in the staff’s 

Upland Erosion Control, Revegetation, and Maintenance Plan (Plan). 

B. DEFINITIONS 

1. "Waterbody" includes any natural or artificial stream, river, or 

drainage with perceptible flow at the time of crossing, and other 

permanent waterbodies such as ponds and lakes: 

a. "minor waterbody" includes all waterbodies less than or 

equal to 10 feet wide at the water's edge at the time of 

construction; 

b. "intermediate waterbody" includes all waterbodies greater 

than 10 feet wide but less than or equal to 100 feet wide at 

the water's edge at the time of construction; and 

c. "major waterbody" includes all waterbodies greater than 

100 feet wide at the water's edge at the time of construction. 

2. "Wetland" includes any area that is not in actively cultivated or 

rotated cropland and that satisfies the requirements of the current 

Federal methodology for identifying and delineating wetlands. 

 

II. PRECONSTRUCTION FILING 

1. The following information shall be filed with the Secretary prior to the 

beginning of construction: 

1. the hydrostatic testing information specified in section VII.B.3. and 

a wetland delineation report as described in section VI.A.1., if 

applicable; and 

2. a schedule identifying when trenching or blasting would occur within 

each waterbody greater than 10 feet wide, or within any designated 

coldwater fishery. The project sponsor shall revise the schedule as 

necessary to provide FERC staff at least 14 days advance notice. 

Changes within this last 14-day period must provide for at least 

48 hours advance notice.

 Docket No. CP13-___-000 

December 2012 

3 01/17/2003 VERSION

B. The following site-specific construction plans required by these 

Procedures must be filed with the Secretary for the review and written 

approval by the Director: 

1. plans for extra work areas that would be closer than 50 feet from a 

waterbody or wetland; 

2. plans for major waterbody crossings; 

3. plans for the use of a construction right-of-way greater than 75 feet 

wide in wetlands; and 

4. plans for horizontal directional drill (HDD) "crossings" of wetlands or 

waterbodies. 

III. ENVIRONMENTAL INSPECTORS 

A. At least one Environmental Inspector having knowledge of the wetland 

and waterbody conditions in the project area is required for each 

construction spread. The number and experience of Environmental 

Inspectors assigned to each construction spread should be appropriate for 

the length of the construction spread and the number/significance of 

resources affected. 

B. The Environmental Inspector's responsibilities are outlined in the Upland 

Erosion Control, Revegetation, and Maintenance Plan (Plan). 

IV. PRECONSTRUCTION PLANNING 

A. A copy of the Stormwater Pollution Prevention Plan (SWPPP) prepared for 

compliance with the U.S. Environmental Protection Agency's (EPA) 

National Stormwater Program General Permit requirements must be 

available in the field on each construction spread. The SWPPP shall 

contain Spill Prevention and Response Procedures that meet the 

requirements of state and Federal agencies. 

1. It shall be the responsibility of the project sponsor and its 

contractors to structure their operations in a manner that reduces 

the risk of spills or the accidental exposure of fuels or hazardous

materials to waterbodies or wetlands. The project sponsor and its 

contractors must, at a minimum, ensure that: 

a. all employees handling fuels and other hazardous materials 

are properly trained; 

b. all equipment is in good operating order and inspected on a 

regular basis; 

c. fuel trucks transporting fuel to on-site equipment travel only 

on approved access roads; 

d. all equipment is parked overnight and/or fueled at least 

100 feet from a waterbody or in an upland area at least 

100 feet from a wetland boundary. These activities can 

occur closer only if the Environmental Inspector finds, in 

advance, no reasonable alternative and the project sponsor 

and its contractors have taken appropriate steps (including 

secondary containment structures) to prevent spills and 

provide for prompt cleanup in the event of a spill; 

e. hazardous materials, including chemicals, fuels, and 

lubricating oils, are not stored within 100 feet of a wetland, 

waterbody, or designated municipal watershed area, unless 

the location is designated for such use by an appropriate 

governmental authority. This applies to storage of these 

materials and does not apply to normal operation or use of 

equipment in these areas; and 

f. concrete coating activities are not performed within 100 feet 

of a wetland or waterbody boundary, unless the location is 

an existing industrial site designated for such use. 

2. The project sponsor and its contractors must structure their 

operations in a manner that provides for the prompt and effective 

cleanup of spills of fuel and other hazardous materials. At a 

minimum, the project sponsor and its contractors must: 

a. ensure that each construction crew (including cleanup 

crews) has on hand sufficient supplies of absorbent and 
 PROJECT-SPECIFIC PROCEDURES 

 Cameron Interstate Pipeline Environmental Plan

 Docket No. CP13-___-000 

December 2012 

5 01/17/2003 VERSION

barrier materials to allow the rapid containment and recovery 

of spilled materials and knows the procedure for reporting 

spills; 

b. ensure that each construction crew has on hand sufficient 

tools and material to stop leaks; 

c. know the contact names and telephone numbers for all local, 

state, and Federal agencies (including, if necessary, the U. 

S. Coast Guard and the National Response Center) that 

must be notified of a spill; and 

d. follow the requirements of those agencies in cleaning up the 

spill, in excavating and disposing of soils or other materials 

contaminated by a spill, and in collecting and disposing of 

waste generated during spill cleanup. 

B. AGENCY COORDINATION 

The project sponsor must coordinate with the appropriate local, state, and 

Federal agencies as outlined in these Procedures and in the Certificate. 

V. WATERBODY CROSSINGS 

A. NOTIFICATION PROCEDURES AND PERMITS 

1. Apply to the U.S. Army Corps of Engineers (COE), or its delegated 

agency, for the appropriate wetland and waterbody crossing 

permits. 

2. Provide written notification to authorities responsible for potable 

surface water supply intakes located within 3 miles downstream of 

the crossing at least 1 week before beginning work in the 

waterbody, or as otherwise specified by that authority. 

3. Apply for state-issued waterbody crossing permits and obtain 

individual or generic section 401 water quality certification or 

waiver. 
 PROJECT-SPECIFIC PROCEDURES 

 Cameron Interstate Pipeline Environmental Plan

December 2012 

6 01/17/2003 VERSION

4. Notify appropriate state authorities at least 48 hours before 

beginning trenching or blasting within the waterbody, or as specified 

in state permits. 

B. INSTALLATION 

1. Time Window for Construction 

Unless expressly permitted or further restricted by the appropriate 

state agency in writing on a site-specific basis, instream work, 

except that required to install or remove equipment bridges, must 

occur during the following time windows: 

a. coldwater fisheries - June 1 through September 30; and 

b. coolwater and warmwater fisheries - June 1 through 

November 30. 

2. Extra Work Areas 

a. Locate all extra work areas (such as staging areas and 

additional spoil storage areas) at least 50 feet away from 

water’s edge, except where the adjacent upland consists of 

actively cultivated or rotated cropland or other disturbed 

land. 

b. The project sponsor shall file with the Secretary for review 

and written approval by the Director, a site-specific 

construction plan for each extra work area with a less than 

50-foot setback from the water's edge, (except where the 

adjacent upland consists of actively cultivated or rotated 

cropland or other disturbed land) and a site-specific 

explanation of the conditions that will not permit a 50-foot 

setback. 

A deviation is being requested from Requirement V.B.2.a to allow additional temporary work 

spaces to be located less than 50 feet away from the edge of specific waterbodies These 

locations and the reason for the deviation request are provided in Table 1.3-1. 
 PROJECT-SPECIFIC PROCEDURES 

 Cameron Interstate Pipeline Environmental Plan 

 Cameron Pipeline Expansion Project 

 Docket No. CP13-___-000 

December 2012 

7 01/17/2003 VERSION

c. Limit clearing of vegetation between extra work areas and 

the edge of the waterbody to the certificated construction 

right-of-way. 

d. Limit the size of extra work areas to the minimum needed to 

construct the waterbody crossing. 

3. General Crossing Procedures 

a. Comply with the COE, or its delegated agency, permit terms 

and conditions. 

b. Construct crossings as close to perpendicular to the axis of 

the waterbody channel as engineering and routing conditions 

permit. 

c. If the pipeline parallels a waterbody, attempt to maintain at 

least 15 feet of undisturbed vegetation between the 

waterbody (and any adjacent wetland) and the construction 

right-of-way. 

d. Where waterbodies meander or have multiple channels, 

route the pipeline to minimize the number of waterbody 

crossings. 

e. Maintain adequate flow rates to protect aquatic life, and 

prevent the interruption of existing downstream uses. 

f. Waterbody buffers (extra work area setbacks, refueling 

restrictions, etc.) must be clearly marked in the field with 

signs and/or highly visible flagging until construction-related 

ground disturbing activities are complete. 

4. Spoil Pile Placement and Control 

a. All spoil from minor and intermediate waterbody crossings, 

and upland spoil from major waterbody crossings, must be 

placed in the construction right-of-way at least 10 feet from 

the water's edge or in additional extra work areas as 

described in section V.B.2. 
 PROJECT-SPECIFIC PROCEDURES 

 Cameron Interstate Pipeline Environmental Plan 

 Cameron Pipeline Expansion Project 

 Docket No. CP13-___-000 

December 2012 

8 01/17/2003 VERSION

b. Use sediment barriers to prevent the flow of spoil or heavily 

silt-laden water into any waterbody. 

5. Equipment Bridges 

a. Only clearing equipment and equipment necessary for 

installation of equipment bridges may cross waterbodies 

prior to bridge installation. Limit the number of such 

crossings of each waterbody to one per piece of clearing 

equipment. 

b. Construct equipment bridges to maintain unrestricted flow 

and to prevent soil from entering the waterbody. Examples 

of such bridges include: 

(1) equipment pads and culvert(s); 

(2) equipment pads or railroad car bridges without 

culverts; 

(3) clean rock fill and culvert(s); and 

(4) flexi-float or portable bridges. 

Additional options for equipment bridges may be utilized that 

achieve the performance objectives noted above. Do not 

use soil to construct or stabilize equipment bridges. 

c. Design and maintain each equipment bridge to withstand 

and pass the highest flow expected to occur while the bridge 

is in place. Align culverts to prevent bank erosion or 

streambed scour. If necessary, install energy dissipating 

devices downstream of the culverts. 

d. Design and maintain equipment bridges to prevent soil from 

entering the waterbody. 

e. Remove equipment bridges as soon as possible after 

permanent seeding unless the COE, or its delegated 

agency, authorizes it as a permanent bridge. 
 PROJECT-SPECIFIC PROCEDURES 

 Cameron Interstate Pipeline Environmental Plan 

 Cameron Pipeline Expansion Project 

 Docket No. CP13-___-000 

December 2012 

9 01/17/2003 VERSION

f. If there will be more than 1 month between final cleanup and 

the beginning of permanent seeding and reasonable 

alternative access to the right-of-way is available, remove 

equipment bridges as soon as possible after final cleanup. 

6. Dry-Ditch Crossing Methods 

a. Unless approved otherwise by the appropriate state agency, 

install the pipeline using one of the dry-ditch methods 

outlined below for crossings of waterbodies up to 30 feet 

wide (at the water's edge at the time of construction) that are 

state-designated as either coldwater or significant coolwater 

or warmwater fisheries. 

b. Dam and Pump 

(1) The dam-and-pump method may be used without 

prior approval for crossings of waterbodies where 

pumps can adequately transfer streamflow volumes 

around the work area, and there are no concerns 

about sensitive species passage. 

(2) Implementation of the dam-and-pump crossing 

method must meet the following performance criteria: 

(I) use sufficient pumps, including on-site backup 

pumps, to maintain downstream flows; 

(ii) construct dams with materials that prevent 

sediment and other pollutants from entering the 

waterbody (e.g., sandbags or clean gravel with 

plastic liner); 

(iii) screen pump intakes; 

(iv) prevent streambed scour at pump discharge; 

and 

(v) monitor the dam and pumps to ensure proper 

operation throughout the waterbody crossing. 

c. Flume Crossing 
 PROJECT-SPECIFIC PROCEDURES 

 Cameron Interstate Pipeline Environmental Plan 

 Cameron Pipeline Expansion Project 

 Docket No. CP13-___-000 

December 2012 

10 01/17/2003 VERSION

The flume crossing method requires implementation of the 

following steps: 

(1) install flume pipe after blasting (if necessary), but 

before any trenching; 

(2) use sand bag or sand bag and plastic sheeting 

diversion structure or equivalent to develop an 

effective seal and to divert stream flow through the 

flume pipe (some modifications to the stream bottom 

may be required in to achieve an effective seal); 

(3) properly align flume pipe(s) to prevent bank erosion 

and streambed scour; 

(4) do not remove flume pipe during trenching, 

pipelaying, or backfilling activities, or initial streambed 

restoration efforts; and 

(5) remove all flume pipes and dams that are not also 

part of the equipment bridge as soon as final cleanup 

of the stream bed and bank is complete. 

d. Horizontal Directional Drill (HDD) 

To the extent they were not provided as part of the precertification process, for each waterbody or wetland that 

would be crossed using the HDD method, provide a plan that 

includes: 

(1) site-specific construction diagrams that show the 

location of mud pits, pipe assembly areas, and all 

areas to be disturbed or cleared for construction; 

(2) a description of how an inadvertent release of drilling 

mud would be contained and cleaned up; and 

(3) a contingency plan for crossing the waterbody or 

wetland in the event the directional drill is 
 PROJECT-SPECIFIC PROCEDURES 

 Cameron Interstate Pipeline Environmental Plan 

 Cameron Pipeline Expansion Project 

 Docket No. CP13-___-000 

December 2012 

11 01/17/2003 VERSION

unsuccessful and how the abandoned drill hole would 

be sealed, if necessary. 

7. Crossings of Minor Waterbodies 

Where a dry-ditch crossing is not required, minor waterbodies may 

be crossed using the open-cut crossing method, with the following 

restrictions: 

a. except for blasting and other rock breaking measures, 

complete instream construction activities (including 

trenching,pipe installation, backfill, and restoration of the 

streambed contours) within 24 hours. Streambanks and 

unconsolidated streambeds may require additional 

restoration after this period; 

b. limit use of equipment operating in the waterbody to that 

needed to construct the crossing; and 

c. equipment bridges are not required at minor waterbodies 

that do not have a state-designated fishery classification 

(e.g., agricultural or intermittent drainage ditches). However, 

if an equipment bridge is used it must be constructed as 

described in section V.B.5. 

8. Crossings of Intermediate Waterbodies 

Where a dry-ditch crossing is not required, intermediate 

waterbodies may be crossed using the open-cut crossing method, 

with the following restrictions: 

a. complete instream construction activities (not including 

blasting and other rock breaking measures) within 48 hours, 

unless site-specific conditions make completion within 48 

hours infeasible; 

b. limit use of equipment operating in the waterbody to that 

needed to construct the crossing; and 
 PROJECT-SPECIFIC PROCEDURES 

 Cameron Interstate Pipeline Environmental Plan 

 Cameron Pipeline Expansion Project 

 Docket No. CP13-___-000 

December 2012 

12 01/17/2003 VERSION

c. all other construction equipment must cross on an 

equipment bridge as specified in section V.B.5. 

9. Crossings of Major Waterbodies 

Before construction, the project sponsor shall file with the Secretary 

for the review and written approval by the Director a detailed, sitespecific construction plan and scaled drawings identifying all areas 

to be disturbed by construction for each major waterbody crossing 

(the scaled drawings are not required for any offshore portions of 

pipeline projects). This plan should be developed in consultation 

with the appropriate state and Federal agencies and should include 

extra work areas, spoil storage areas, sediment control structures, 

etc., as well as mitigation for navigational issues. 

The Environmental Inspector may adjust the final placement of the 

erosion and sediment control structures in the field to maximize 

effectiveness. 

10. Temporary Erosion and Sediment Control 

Install sediment barriers (as defined in section IV.F.2.a. of the Plan) 

immediately after initial disturbance of the waterbody or adjacent 

upland. Sediment barriers must be properly maintained throughout 

construction and reinstalled as necessary (such as after backfilling 

of the trench) until replaced by permanent erosion controls or 

restoration of adjacent upland areas is complete. Temporary 

erosion and sediment control measures are addressed in more 

detail in the Plan; however, the following specific measures must be 

implemented at stream crossings: 

a. install sediment barriers across the entire construction rightof-way at all waterbody crossings, where necessary to 

prevent the flow of sediments into the waterbody. 

Removable sediment barriers (or driveable berms) must be 

installed across the travel lane. These removable sediment 

barriers can be removed during the construction day, but 

must be re-installed after construction has stopped for the 

day and/or when heavy precipitation is imminent;

b. where waterbodies are adjacent to the construction right-ofway, install sediment barriers along the edge of the 

construction right-of-way as necessary to contain spoil and 

sediment within the construction right-of-way; and 

c. use trench plugs at all waterbody crossings, as necessary, to 

prevent diversion of water into upland portions of the pipeline 

trench and to keep any accumulated trench water out of the 

waterbody. 

11. Trench Dewatering 

Dewater the trench (either on or off the construction right-of-way) in 

a manner that does not cause erosion and does not result in 

heavily silt-laden water flowing into any waterbody. Remove the 

dewatering structures as soon as possible after the completion of 

dewatering activities. 

C. RESTORATION 

1. Use clean gravel or native cobbles for the upper 1 foot of trench 

backfill in all waterbodies that contain coldwater fisheries. 

2. For open-cut crossings, stabilize waterbody banks and install 

temporary sediment barriers within 24 hours of completing instream 

construction activities. For dry-ditch crossings, complete 

streambed and bank stabilization before returning flow to the 

waterbody channel. 

3. Return all waterbody banks to preconstruction contours or to a 

stable angle of repose as approved by the Environmental Inspector. 

4. Application of riprap for bank stabilization must comply with COE, 

or its delegated agency, permit terms and conditions. 

5. Unless otherwise specified by state permit, limit the use of riprap to 

areas where flow conditions preclude effective vegetative 

stabilization techniques such as seeding and erosion control fabric.

6. Revegetate disturbed riparian areas with conservation grasses and 

legumes or native plant species, preferably woody species. 

7. Install a permanent slope breaker across the construction right-ofway at the base of slopes greater than 5 percent that are less than 

50 feet from the waterbody, or as needed to prevent sediment 

transport into the waterbody. In addition, install sediment barriers 

as outlined in the Plan. 

In some areas, with the approval of the Environmental Inspector, an 

earthen berm may be suitable as a sediment barrier adjacent to the 

waterbody. 

8. Sections V.C.3. through V.C.6. above also apply to those perennial 

or intermittent streams not flowing at the time of construction. 

D. POST-CONSTRUCTION MAINTENANCE 

1. Limit vegetation maintenance adjacent to waterbodies to allow a 

riparian strip at least 25 feet wide, as measured from the 

waterbody's mean high water mark, to permanently revegetate with 

native plant species across the entire construction right-of-way. 

However, to facilitate periodic pipeline corrosion/leak surveys, a 

corridor centered on the pipeline and up to 10 feet wide may be 

maintained in a herbaceous state. In addition, trees that are 

located within 15 feet of the pipeline that are greater than 15 feet in 

height may be cut and removed from the permanent right-of-way. 

2. Do not use herbicides or pesticides in or within 100 feet of a 

waterbody except as allowed by the appropriate land management 

or state agency. 

VI. WETLAND CROSSINGS 

A. GENERAL 

1. The project sponsor shall conduct a wetland delineation using the 

current Federal methodology and file a wetland delineation report 

with the Secretary before construction. This report shall identify: 
 PROJECT-SPECIFIC PROCEDURES 

 Cameron Interstate Pipeline Environmental Plan 

 Cameron Pipeline Expansion Project 

 Docket No. CP13-___-000 

December 2012 

15 01/17/2003 VERSION

a. by milepost all wetlands that would be affected; 

b. the National Wetlands Inventory (NWI) classification for each 

wetland; 

c. the crossing length of each wetland in feet; and 

d. the area of permanent and temporary disturbance that would 

occur in each wetland by NWI classification type. 

The requirements outlined in this section do not apply to wetlands 

in actively cultivated or rotated cropland. Standard upland 

protective measures, including workspace and topsoiling 

requirements, apply to these agricultural wetlands. 

2. Route the pipeline to avoid wetland areas to the maximum extent 

possible. If a wetland cannot be avoided or crossed by following an 

existing right-of-way, route the new pipeline in a manner that 

minimizes disturbance to wetlands. Where looping an existing 

pipeline, overlap the existing pipeline right-of-way with the new 

construction right-of-way. In addition, locate the loop line no more 

than 25 feet away from the existing pipeline unless site-specific 

constraints would adversely affect the stability of the existing 

pipeline. 

3. Limit the width of the construction right-of-way to 75 feet or less. 

Prior written approval of the Director is required where topographic 

conditions or soil limitations require that the construction right-ofway width within the boundaries of a federally delineated wetland 

be expanded beyond 75 feet. Early in the planning process the 

project sponsor is encouraged to identify site-specific areas where 

existing soils lack adequate unconfined compressive strength that 

would result in excessively wide ditches and/or difficult to contain 

spoil piles. 

A deviation is being requested from Requirement IV.A.3 to allow a construction right-of-way 

width greater than 75 feet in specific wetland areas. These locations and the reason for the 

deviation request are provided in Table 1.3-1.

16 01/17/2003 VERSION

4. Wetland boundaries and buffers must be clearly marked in the field 

with signs and/or highly visible flagging until construction-related 

ground disturbing activities are complete. 

5. Implement the measures of sections V. and VI. in the event a 

waterbody crossing is located within or adjacent to a wetland 

crossing. If all measures of sections V. and VI. cannot be met, the 

project sponsor must file with the Secretary a site-specific crossing 

plan for review and written approval by the Director before 

construction. This crossing plan shall address at a minimum: 

a. spoil control; 

b. equipment bridges; 

c. restoration of waterbody banks and wetland hydrology; 

d. timing of the waterbody crossing; 

e. method of crossing; and 

f. size and location of all extra work areas. 

6. Do not locate aboveground facilities in any wetland, except where 

the location of such facilities outside of wetlands would prohibit 

compliance with U.S. Department of Transportation regulations. 

B. INSTALLATION 

1. Extra Work Areas and Access Roads 

a. Locate all extra work areas (such as staging areas and 

additional spoil storage areas) at least 50 feet away from 

wetland boundaries, except where the adjacent upland 

consists of actively cultivated or rotated cropland or other 

disturbed land. 

A deviation is being requested from Requirement IV.B.1.a. to locate additional temporary 

workspaces within 50 feet of specific wetland boundaries. These locations and the reason for 

the deviation request are provided in Table 1.3-1.

 Cameron Interstate Pipeline Environmental Plan 

 Cameron Pipeline Expansion Project 

 Docket No. CP13-___-000 

December 2012 

17 01/17/2003 VERSION

b. The project sponsor shall file with the Secretary for review 

and written approval by the Director, a site-specific 

construction plan for each extra work area with a less than 

50-foot setback from wetland boundaries (except where 

adjacent upland consists of actively cultivated or rotated 

cropland or other disturbed land) and a site-specific 

explanation of the conditions that will not permit a 50-foot 

setback. 

c. Limit clearing of vegetation between extra work areas and 

the edge of the wetland to the certificated construction rightof-way. 

d. The construction right-of-way may be used for access when 

the wetland soil is firm enough to avoid rutting or the 

construction right-of-way has been appropriately stabilized to 

avoid rutting (e.g., with timber riprap, prefabricated 

equipment mats, or terra mats). 

In wetlands that cannot be appropriately stabilized, all 

construction equipment other than that needed to install the 

wetland crossing shall use access roads located in upland 

areas. Where access roads in upland areas do not provide 

reasonable access, limit all other construction equipment to 

one pass through the wetland using the construction right-ofway. 

e. The only access roads, other than the construction right-ofway, that can be used in wetlands without Director approval, 

are those existing roads that can be used with no 

modification and no impact on the wetland. 

2. Crossing Procedures 

a. Comply with COE, or its delegated agency, permit terms and 

conditions 
 PROJECT-SPECIFIC PROCEDURES 

 Cameron Interstate Pipeline Environmental Plan 

 Cameron Pipeline Expansion Project 

 Docket No. CP13-___-000 

December 2012 

18 01/17/2003 VERSION

b. Assemble the pipeline in an upland area unless the wetland 

is dry enough to adequately support skids and pipe. 

c. Use "push-pull" or "float" techniques to place the pipe in the 

trench where water and other site conditions allow. 

d. Minimize the length of time that topsoil is segregated and the 

trench is open. 

e. Limit construction equipment operating in wetland areas to 

that needed to clear the construction right-of-way, dig the 

trench, fabricate and install the pipeline, backfill the trench, 

and restore the construction right-of-way. 

f. Cut vegetation just aboveground level, leaving existing root 

systems in place, and remove it from the wetland for 

disposal. 

g. Limit pulling of tree stumps and grading activities to directly 

over the trenchline. Do not grade or remove stumps or root 

systems from the rest of the construction right-of-way in 

wetlands unless the Chief Inspector and Environmental 

Inspector determine that safety-related construction 

constraints require grading or the removal of tree stumps 

from under the working side of the construction right-of-way. 

h. Segregate the top 1 foot of topsoil from the area disturbed by 

trenching, except in areas where standing water is present 

or soils are saturated or frozen. Immediately after backfilling 

is complete, restore the segregated topsoil to its original 

location. 

i. Do not use rock, soil imported from outside the wetland, tree 

stumps, or brush riprap to support equipment on the 

construction right-of-way. 

j. If standing water or saturated soils are present, or if 

construction equipment causes ruts or mixing of the topsoil 

and subsoil in wetlands, use low-ground-weight construction

prefabricated equipment mats, or terra mats. 

k. Do not cut trees outside of the approved construction work 

area to obtain timber for riprap or equipment mats. 

l. Attempt to use no more than two layers of timber riprap to 

support equipment on the construction right-of-way. 

m. Remove all project-related material used to support 

equipment on the construction right-of-way upon completion 

of construction. 

3. Temporary Sediment Control 

Install sediment barriers (as defined in section IV.F.2.a. of the Plan) 

immediately after initial disturbance of the wetland or adjacent 

upland. Sediment barriers must be properly maintained throughout 

construction and reinstalled as necessary (such as after backfilling 

of the trench). Except as noted below in section VI.B.3.c., maintain 

sediment barriers until replaced by permanent erosion controls or 

restoration of adjacent upland areas is complete. Temporary 

erosion and sediment control measures are addressed in more 

detail in the Plan. 

a. Install sediment barriers across the entire construction rightof-way immediately upslope of the wetland boundary at all 

wetland crossings where necessary to prevent sediment flow 

into the wetland. 

b. Where wetlands are adjacent to the construction right-of-way 

and the right-of-way slopes toward the wetland, install 

sediment barriers along the edge of the construction right-ofway as necessary to prevent sediment flow into the wetland. 

c. Install sediment barriers along the edge of the construction 

right-of-way as necessary to contain spoil and sediment 

within the construction right-of-way through wetlands. 

Remove these sediment barriers during right-of-way 

cleanup.

4. Trench Dewatering 

Dewater the trench (either on or off the construction right-of-way) in 

a manner that does not cause erosion and does not result in 

heavily silt-laden water flowing into any wetland. Remove the 

dewatering structures as soon as possible after the completion of 

dewatering activities. 

C. RESTORATION 

1. Where the pipeline trench may drain a wetland, construct trench 

breakers and/or seal the trench bottom as necessary to maintain 

the original wetland hydrology. 

2. For each wetland crossed, install a trench breaker at the base of 

slopes near the boundary between the wetland and adjacent 

upland areas. Install a permanent slope breaker across the 

construction right-of-way at the base of a slopes greater than 5 

percent where the base of the slope is less than 50 feet from the 

wetland, or as needed to prevent sediment transport into the 

wetland. In addition, install sediment barriers as outlined in the 

Plan. In some areas, with the approval of the Environmental 

Inspector, an earthen berm may be suitable as a sediment barrier 

adjacent to the wetland. 

3. Do not use fertilizer, lime, or mulch unless required in writing by the 

appropriate land management or state agency. 

4. Consult with the appropriate land management or state agency to 

develop a project-specific wetland restoration plan. The restoration 

plan should include measures for re-establishing herbaceous 

and/or woody species, controlling the invasion and spread of 

undesirable exotic species (e.g., purple loosestrife and phragmites), 

and monitoring the success of the revegetation and weed control 

efforts. Provide this plan to the FERC staff upon request. 

5. Until a project-specific wetland restoration plan is developed and/or 

implemented, temporarily revegetate the construction right-of-way 
 PROJECT-SPECIFIC PROCEDURES 

 Cameron Interstate Pipeline Environmental Plan

 Docket No. CP13-___-000 

December 2012 

21 01/17/2003 VERSION

with annual ryegrass at a rate of 40 pounds/acre (unless standing 

water is present). 

6. Ensure that all disturbed areas successfully revegetate with 

wetland herbaceous and/or woody plant species. 

7. Remove temporary sediment barriers located at the boundary 

between wetland and adjacent upland areas after upland 

revegetation and stabilization of adjacent upland areas are judged 

to be successful as specified in section VII.A.5. of the Plan. 

D. POST-CONSTRUCTION MAINTENANCE 

1. Do not conduct vegetation maintenance over the full width of the 

permanent right-of-way in wetlands. However, to facilitate periodic 

pipeline corrosion/leak surveys, a corridor centered on the pipeline 

and up to 10 feet wide may be maintained in a herbaceous state. 

In addition, trees within 15 feet of the pipeline that are greater than 

15 feet in height may be selectively cut and removed from the 

permanent right-of-way. 

2. Do not use herbicides or pesticides in or within 100 feet of a 

wetland, except as allowed by the appropriate land management 

agency or state agency. 

3. Monitor and record the success of wetland revegetation annually 

for the first 3 years after construction or until wetland revegetation 

is successful. At the end of 3 years after construction, file a report 

with the Secretary identifying the status of the wetland revegetation 

efforts. Include the percent cover achieved and problem areas 

(weed invasion issues, poor revegetation, etc.). Continue to file a 

report annually until wetland revegetation is successful. 

4. Wetland revegetation shall be considered successful if the cover of 

herbaceous and/or woody species is at least 80 percent of the type, 

density, and distribution of the vegetation in adjacent wetland areas 

that were not disturbed by construction. If revegetation is not 

successful at the end of 3 years, develop and implement (in 

consultation with a professional wetland ecologist) a remedial 
 PROJECT-SPECIFIC PROCEDURES

revegetation plan to actively revegetate the wetland. Continue 

revegetation efforts until wetland revegetation is successful. 

VII. HYDROSTATIC TESTING 

A. NOTIFICATION PROCEDURES AND PERMITS 

1. Apply for state-issued water withdrawal permits, as required. 

2. Apply for National Pollutant Discharge Elimination System (NPDES) 

or state-issued discharge permits, as required. 

3. Notify appropriate state agencies of intent to use specific sources at 

least 48 hours before testing activities unless they waive this 

requirement in writing. 

B. GENERAL 

1. Perform 100 percent radiographic inspection of all pipeline section 

welds or hydrotest the pipeline sections, before installation under 

waterbodies or wetlands. 

2. If pumps used for hydrostatic testing are within 100 feet of any 

waterbody or wetland, address the operation and refueling of these 

pumps in the project’s Spill Prevention and Response Procedures. 

3. The project sponsor shall file with the Secretary before construction 

a list identifying the location of all waterbodies proposed for use as 

a hydrostatic test water source or discharge location. 

C. INTAKE SOURCE AND RATE 

1. Screen the intake hose to prevent entrainment of fish. 

2. Do not use state-designated exceptional value waters, waterbodies 

which provide habitat for federally listed threatened or endangered 

species, or waterbodies designated as public water supplies, unless 

appropriate Federal, state, and/or local permitting agencies grant 

written permission.

3. Maintain adequate flow rates to protect aquatic life, provide for all 

waterbody uses, and provide for downstream withdrawals of water 

by existing users. 

4. Locate hydrostatic test manifolds outside wetlands and riparian 

areas to the maximum extent practicable. 

D. DISCHARGE LOCATION, METHOD, AND RATE 

1. Regulate discharge rate, use energy dissipation device(s), and 

install sediment barriers, as necessary, to prevent erosion, 

streambed scour, suspension of sediments, or excessive 

streamflow. 

2. Do not discharge into state-designated exceptional value waters, 

waterbodies which provide habitat for federally listed threatened or 

endangered species, or waterbodies designated as public water 

supplies, unless appropriate Federal, state, and local permitting 

agencies grant written permission.

HORIZONTAL DIRECTIONAL DRILL PLAN 

1.0 INTRODUCTION 

This horizontal directional drill (HDD) plan identifies specific procedures and steps to 

contain inadvertent releases of drilling mud for water bodies that are crossed using HDD 

techniques. Cameron Interstate Pipeline, LLC (Cameron Interstate) proposes to utilize 

six directionally drills on the Cameron Pipeline Expansion Project (Pipeline Project). 

2.0 HORIZONTAL DIRECTIONAL DRILLING PROCESS 

Installation of a pipeline by HDD is generally accomplished in three stages. The first 

stage consists of directionally drilling a small diameter pilot hole along a predetermined 

path. The second stage enlarges this pilot hole to a diameter that will accommodate the 

pipeline. Numerous "reaming" passes will be necessary with each pass enlarging the 

diameter of the pilot hole incrementally. The third stage involves pulling the pipeline 

through the enlarged hole. 

During the drilling of the pilot hole, directional control is achieved by using a non-rotating 

drill string with an asymmetrical leading edge. The asymmetry of the leading edge 

creates a steering bias, which allows the operator to control the direction of the drill bit. 

The actual path of the pilot hole is monitored during drilling to take periodic readings of 

the inclination and azimuth. These readings are used to calculate the horizontal and 

vertical coordinates along the pilot holes relative to the initial entry point on the surface. 

Once the pilot hole is complete, it is enlarged using reaming tools that are often custom 

made for a particular diameter pipe or type of soil. The reamers are typically attached to 

the drill string at the exit point and are rotated and drawn to the drilling rig, thus 

enlarging the pilot hole with each pass. Pipe installation is accomplished by attaching a 

prefabricated pull section behind a reaming assembly at the exit point and pulling the 

entire assembly back to the drilling rig. When the pipe is in place beneath the water 

body or other feature, tie-in welds on each end complete the crossing. 

Ideally, HDD involves no disturbance to the bed or banks of the river. However, it is 

possible that geologic irregularities could be encountered during drilling and result in 

drill mud release. This plan describes the potential for failure of horizontal directional 

drilling and the contingency methods that would be implemented in the event drilling 

was to fail. 

Failure of a HDD can be defined two ways: either as the release of drilling mud during 

the drilling process, or due to the inability to complete the crossing using the HDD

techniques. The feasibility of the HDD method is primarily dependent on the local 

geologic setting. Typically, HDD is not feasible in areas of glacial till or outwash 

interspersed with boulders and cobbles, fractured bedrock, or non-cohesive course 

sands and gravels. These formations increase the likelihood drilling would fail due to 

refusal of the drill bit, loss of drilling fluid through fractures or weak areas in the ground, 

or collapse of the bore hole in non-cohesive unstable substrate.

3.0 MONITORING PROCEDURES 

The Environmental lnspector and/or Construction lnspector will continuously monitor 

operations during HDD activities. Monitoring activities will include: 

 Visual inspection along the drill path, including monitoring the water body for 

evidence of a release. 

 Continuous examination of drilling fluid pressures and return flows. 

The drilling operator will provide information regarding drilling conditions to the 

Environmental inspector and/or Construction lnspector throughout the course of drilling 

activities. The Environmental lnspector and/or Construction lnspector will document 

relevant monitoring observations. 

4.0 NOTIFICATION PROCEDURES 

If in the course of an inspection an inadvertent release is discovered, steps will be taken 

by construction personnel to contain the release as described below in Section V, 

Corrective Action and Cleanup. Notification procedures of Cameron Interstate’s 

construction management personnel and regulatory agencies are detailed in this 

section. 

If monitoring indicates an in-stream release, the Environmental Inspector and/or 

Construction lnspector will immediately notify Cameron Interstate’s construction 

management. Cameron Interstate will notify appropriate federal and state agencies as 

soon as practical by telephone and/or facsimile of an in-stream release event, detailing 

the nature of the release and corrective actions being taken, and will discuss with the 

notified agencies whether additional measures need to be implemented. 

5.0 CORRECTIVE ACTION AND CLEANUP 

By monitoring HDD operations continuously, Cameron Interstate intends to avoid 

problems before they occur. In addition, containment equipment including earth-moving 

equipment, portable pumps, hand tools, sand, hay bales, silt fence, lumber will be 

readily available at the drill site.

 The drilling contractor will decide what modifications to make to the drilling 

technique or composition of drilling fluid (i.e., thickening of fluid by increasing 

bentonite content) to reduce or stop minor losses of drilling fluid. 

 If a minor bore path void is encountered during drilling; making a slight 

change in the direction of the bore path may avoid loss of circulation. 

 If the bore head becomes lodged resulting in loss of drilling pressure, the 

borehole may be sized by moving the bore head back and forth to dislodge 

the stuck materials.

However, if a release does occur, the following measures will be implemented to stop or 

minimize the release and to clean it up. 

Release in the Waterbody and or Wetlands: 

If necessary, drilling operations will be reduced or suspended to assess the extent of 

the release and to implement other possible corrective actions. Notifications should be 

carried out as indicated in Section 4. The hydrostatic pressure of the waterbody is likely 

to negate the pressure of the drilling fluid at the release site and will naturally limit the 

duration of the release. However, if an inadvertent release is observed in a waterbody, 

the following measures will be implemented. 

 Immediately notify the environmental inspector, the Cameron Interstate 

inspector and the HDD contractor. The environmental inspector will monitor 

the extent of the drilling fluid plume. 

 If bentonite material flows overland prior to entering the stream installation of 

silt fencing or sandbags dams at the point of entry will be used to reduce or 

stop the flow; if the vent is directly into the stream other means to isolate the 

vent site from the flowing stream will be used. 

 Using a vacuum truck or pump(s), with sufficient house, personnel will 

remove the bentonite, working from downstream to upstream, to allow 

maximum visibility. Hand tools may be used to scarify the sediments and 

ensure removal to the maximum extent practical. 

 If necessary, water may be diverted using a coffer dam to isolate the impact 

area. Only a portion of the stream will be diverted to minimize dewatering 

impacts. Water will be able to pass through the site in its natural condition. 

 Any disturbed soils will be stabilized immediately. 

 Disturbance of vegetation will be kept to a minimum and all disturbed 

vegetation will be restored and or replanted with native species, to eventually 

recreate the functional values of the lost vegetation. 

 Damaged riffle and pool sediment strata will be re-contoured to the extent 

practical.

 The environmental inspector will evaluate the release to determine if 

containment structures are warranted and can effectively contain the release. 

When making this determination, the environmental inspector will also 

consider if placement of containment structures will cause additional adverse 

environmental impact. 

 Upon completion of the drilling operations, Cameron Interstate will consult 

with applicable regulatory agencies to determine any final clean-up 

requirements for the inadvertent release. 

Release on Land: 

 If a land release is detected, the drilling crew will take immediate corrective 

action to contain the release and to avoid migration off-site. 

 The contractor will construct pits and berms around the borehole entry and 

exit point to contain inadvertent releases onto the ground. 

 Any drilling mud released into the pits will be pumped by contractor personnel 

into a mud-processing unit for recycling of drilling fluid and separation of 

cuttings. 

 Additional berms may be constructed around the bore pit as directed by the 

Environmental lnspector and/or Construction Inspector to avoid release 

materials from flowing into the water body. 

 If the amount of an on-land release does not allow practical collection, the 

affected area will be diluted with fresh water and allowed to dry. Steps will be 

taken (such as berm, silt fence, and/or hay bale installation) to avoid heavy 

silt laden water from flowing into the water body. 

 If hand tools cannot contain a small on-land release, small collection sumps 

(less than 5 cubic yards) may be constructed to pump the release material 

into the mud-processing system. 

6.0 ABANDONMENT 

If corrective actions do not prevent or control releases from occurring into the water 

body, Cameron Interstate may opt to re-drill the hole along a different alignment. The 

following steps will be implemented to abandon the drill hole: 

 The method for sealing the abandoned drill hole is to pump thickened drilling 

fluid into the hole as the drill assembly is extracted, and using cement grout to 

make a cap. 

 Closer to the surface (within approximately 10 feet of the surface), a soil cap 

will be installed by filling with soil extracted during construction of the pit and 

berms. 

 The borehole entry location will be graded by the contractor to its original 

grade and condition after the drill hole has been abandoned.
