Suite 120 Raleigh, NC 27615 Subject: Patriot Project - Permit Application Dear Mr. Burch: '01184, 207 775-4495 Fax 207 775-1031 On behalf of East Tennessee Natural Gas (ETNG), Duke Engineering & Services, Inc. is pleased to submit this permit application for the Patriot Project. In North Carolina, the Patriot Project consists of the following: construction of a 24-inch-diameter mainline (7.69 miles) in Rockingham County, a 16-inch- diameter lateral (0.39 miles) that will extend from the 24-inch-diamter lateral in Rockingham County, and the construction of a meter station between the 24-inch-diameter pipeline and the existing Transcontinental Gas Pipeline Corporation mainline in Rockingham County. The Patriot Project includes not only the above referenced construction in North Carolina, but also expansion of existing natural gas pipeline facilities through Tennessee and Virginia. The purpose of Patriot Project, which will transport 500 million cubic feet a day of natural gas, is to serve the growing natural gas demand in the southeast, enhance the regional supply basin, and bring natural gas supply to areas that currently have none. The proposed project will cross 11 wetlands in North Carolina (see Table 3-1). No wetlands will be affected by construction of any of the aboveground facilities. Construction will result in the disturbance of about 4.4 acres of wetlands but there will only be a loss of 2.7 acres of forested wetlands that will be converted to emergent or scrub/shrub wetland. ETNG would implement the procedures and mitigation measures contained in its E&SCP. Please find enclosed the permit application, Erosion and Sedimentation Control Plan, Wetland Delineation Report, and Endangered and Threatened Species Report. In addition, please find in Appendix H copies of meeting minutes with North Carolina agencies and John Thomas of your staff, respectively.

Mitigation DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC Division of Water Quality for projects involving greater than or equal to one acre of impacts to freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial streams. USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide Permits, published in the Federal Register on March 9, 2000, mitigation will be required when necessary to ensure that adverse effects to the aquatic environment are minimal. Factors including size and type of proposed impact and function and relative value of the impacted aquatic resource will be considered in determining acceptability of appropriate and practicable mitigation as proposed. Examples of mitigation that may be appropriate and practicable include, but are not limited to: reducing the size of the project; establishing and maintaining wetland and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of aquatic resource functions and values by creating, restoring, enhancing, or preserving similar functions and values, preferable in the same watershed. If mitigation is required for this project, a copy of the mitigation plan must be attached in order for USACE or DWQ to consider the application complete for processing. Any application lacking a required mitigation plan or NCWRP concurrence shall be placed on hold as incomplete. An applicant may also choose to review the current guidelines for stream restoration in DWQ's Draft Technical Guide for Stream Work in North Carolina, available at http://h2o.enr.state.nc.us/ncwetlands/strmgide.html. Provide a brief description of the proposed mitigation plan. The description should provide as much information as possible, including, but not limited to: site location (attach directions and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet) of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view, preservation mechanism (e.g., deed restrictions, conservation easement, etc.), and a description of the current site conditions and proposed method of construction. Please attach a separate sheet if more space is needed. N/A Page 8 of 12 2. Mitigation may also be made by payment into the North Carolina Wetlands Restoration Program (NCWRP) with the NCWRP's written agreement. Check the box indicating that you would like to pay into the NCWRP. Please note that payment into the NCWRP must be reviewed and approved before it can be used to satisfy mitigation requirements. Applicants will be notified early in the review process by the 401/Wetlands Unit if payment into the NCWRP is available as an option. For additional information regarding the application process for the NCWRP, check the NCWRP website at ht!p:flh2o.enr.state.nc.us/LAM/index.htm. If use of the NCWRP is proposed, please check the appropriate box on page three and provide the following information: Amount of stream mitigation requested (linear feet): Amount of buffer mitigation requested (square feet): Amount of Riparian wetland mitigation requested (acres): Amount of Non-riparian wetland mitigation requested (acres): Amount of Coastal wetland mitigation requested (acres): IX.

Portland, Maine AND FOSTER WHEELER ENVIRONMENTAL CORPORATION Langhorne, Pennsylvania OCTOBER 2001 PATRIOT PROJECT MEETING MINUTES LOCATION: U.S. Army Corps of Engineers, Raleigh, NC Office DATE: August 9, 2001 PURPOSE: To discuss Section 404 Permit Application and State Permits ATTENDEES: Gil Paquette (DE&S) Lucia Allen (DE&S) John Thomas (ACOE) Patrick Grogan (NCDENR) DISCUSSION Gil Paquette opened discussions with an overview of the geographic extent of the Patriot Project and provided specifics on the Patriot Extension in North Carolina. John Thomas asked how big the pipe was going to be. Gil responded that it would be a 24" pipe. In addition, Mr. Thomas asked how big the permanent easement would be. Gil told him that it would be 50 feet. Mr. Thomas asked if the standard construction method for stream crossings would involve open-cut. Gil said that ETNG only planned to use the HDD method for the Smith River in North Carolina and all others would be open-cut. Mr. Thomas said that a 404 permit would not be necessary for streams using the HDD crossing method. Gil discussed the nine streams and various wetlands crossed in North Carolina. Mr. Thomas suggested the HDD for the large wetland crossing (639' in length). He also added that HDD should be used for any wetland crossing over 150' in length. If not, ETNG would need to justify why. Patrick Grogan said that the state would also require a seepage block every 150 feet within wetlands and at the end of each wetland that would not be directionally drilled. John Thomas explained that the project would qualify for a NWP #12 and that this NWP does not stipulate an acreage limit because there are no permanent impacts to wetlands. Gil explained that while there will be an alteration of type of wetland (i.e., forested wetland to scrub-shrub or emergent) there would be no permanent loss of wetland cover. He asked Gil if ETNG would be maintaining the corridor. Gil said that they would. Gil explained that ETNG would not conduct vegetative maintenance over the full width of the easement. For maintenance of wetlands within the ROW a 10-foot wide corridor centered on the pipeline will be maintained in a herbaceous state and in uplands as much as a 30-foot wide corridor will 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. John Thomas asked if the wetlands would be grubbed or graded during construction. Gil said that they would not be grubbed or graded and that that is a FERC requirement. John Thomas discussed a previous pipeline project that was built about 7 to 8 years ago that had some safety and environmental violations. The Cardinal Project left a poor impression on the state of North Carolina. John Thomas said that the NWP #12 PCN form is a joint form with the NC Water Quality Division. Patrick Grogan said that he did not expect erosion issues along the 7 miles of the Project within North Carolina to be a problem, or that having 7 miles of open trench at one time would be an issue either. He also stated that straw bales are not allowed in North Carolina for erosion control. He said that 57 or #5 stone could be used for outlets of waterbars. Mr. Grogan said that he would send Lucia the address for the Winston-Salem office to send the E&SCP. Gil asked Mr. Grogan if ETNG should show specific erosion control structures drawing for each waterbody. Mr. Grogan said that ETNG could use size-grouped typicals and that in-stream construction methods should be clarified. Gil asked Mr. Grogan if any NPDES NOI are required for hydrostatic testing. Mr. Grogan replied that they are not required by the state. Mr. Grogan informed Gil and Lucia that the state of North Carolina requires a perpendicular (or as close to perpendicular) crossing for 401 Water Quality Certification. The state also requires that in-stream work be reduced to a 30' ROW. Gil asked for clarification "does that mean the ROW is 30' or the in-stream work is 30' or less". Mr. Grogan clarified that this meant the instream work be 30 feet or less [i.e., the trench] and that the ROW could be over 30 feet. CONCLUSION John Thomas of the Raleigh, NC Army Corps of Engineers would prefer ETNG use a NWP 912. PATRIOT PROJECT MEETING MINUTES LOCATION: North Carolina Department of Natural Heritage, Archdale Building, Raleigh, North Carolina DATE: August 9, 2001 PURPOSE: To discuss proposed endangered and threatened species surveys for the Patriot Project ATTENDEES: Gil Paquette (DE&S) Lucia Allen (DE&S) Harry LeGrand (NHP) Danielle Pender (NCWRC) DISCUSSION General project overview, as well as details regarding surveys and mitigation, were discussed during the meeting. SMOOTH CONEFLOWER and E&T PLANT SURVEYS Gil Paquette reviewed the results of the smooth coneflower surveys that were recently conducted by DE&S in North Carolina. He stated that no smooth coneflower populations were discovered during the survey, but that a number of other species of concern were found and will be documented in the report that will be issued in the future when all the surveys for the Project have been completed. Gil and Mr. LeGrand reviewed mapped, known locations of smooth coneflower in Rockingham County, North Carolina. A known population of Berberis was identified on the Natural Heritage Program map provided by Mr. LeGrand, around the crossing of SSR 770 and the old railroad bed. Gil asked Mr. LeGrand what kind of mitigation he would propose. Mr. LeGrand said he wasn't aware of any. Danielle Pender asked if there were any relocation methods that may be effective in this situation. Gil Paquette discussed relocation methods used during construction of Maritimes & Northeast Phase II pipeline through Maine. Gil proposed that ETNG revisit this idea when the ROW is finalized for the area and that the digital information be overlaid onto the construction corridor to help define the appropriate mitigation if any. He said that ETNG would involve Chick Gaddy if relocation was the preferred form of mitigation. Gil asked Mr. LeGrand if Chick could relocate this plant if necessary. Harry said that that he could. Danielle Pender asked if ETNG was planning on using HDD method for crossing the Smith River. Gil said that ETNG was planning on using that method for the Smith. Gil also explained the timing restrictions for length of time allowed for in-stream construction (e.g.: "tie in"). Ms. Pender asked how ETNG would survey or mitigate for fish. Gil responded that ETNG proposed to use their established best management practices (BMPs). He went on to explain various methods for crossing streams that adhere to these BMPs, such as dam and pump, and dry cut. MUSSELS Gil asked Mr. LeGrand and Ms. Pender if the proposed survey methodology for the green floater and James spinymussel were adequate. They agreed that they were. Danielle brought to attention the text error in Appendix A on the Survey Location Maps that the unit "feet" was used instead of "meters" to describe the area of the streams to be surveyed for mussels. The text in the body of the report reflected the correct dimensions using meters. Danielle Pender listed other mussel species she would like ETNG to survey for during low water conditions at the Extension crossings of Dry Creek and Martin Creek. The mussels to be surveyed for are: ? James spinymussel ? Green floater ? Knotched rainbow ? Atlantic pigtoe Danielle also mentioned that there are several fish species of concern that we should wathc for during our mussel surveys. Danielle Pender asked what is the driving force behind the need for the pipeline. Gil discussed the need for natural gas for the proposed power plant to be located in Henry County Virginia, as well as a growing energy demand in the southeast. He informed Ms. Pender that ETNG filing with the FERC contains a section on the "necessity" for the pipeline and is now in the public record. Ms. Pender asked what would be done for any small animals that may fall or wander into the open trench. Gil said that they would not be buried alive and that the construction crew or environmental inspector would remove any animals found unharmed. Ms. Pender said that she would inform DE&S of the timing restrictions regarding spawning season for E&T fish species. Mr. LeGrand said that the state does have a GIS database available for a fee, but DE&S would need to go to NHP for clarification for identifying specific species. Gil asked if there were any other comments or questions. Ms. Pender said the ETNG should coordinate with the local municipalities to discuss secondary cumulative impacts (e.g: growth/sprawl associated with new pipeline). Gil said that this pipeline would not be used for individual home use, that it is feeding natural gas to a power plant. CONCLUSION: ? Danielle Pender will be providing DE&S with a list of timing restrictions for E&T fish species. ? Mussel surveys will be conducted within the next couple of months to adhere to the request that the surveys be conducted during low water conditions. ? DE&S will be submitting an E&T report when the NC surveys have been completed. SUPPLEMENTAL (provided by Danielle Pender, NCWRC, after our meeting) 1. Streams should not be disturbed during 1 February to 30 June to avoid impacts to any spawning fish species. The early date in February includes the spawning time of the Bigeye jumprock, which also occurs in the Dan River Drainage. 2. Efforts should be made to avoid removal of large trees at the edges of the construction corridors. Re-seed the disturbed areas with seed mixtures that are beneficial to wildlife. Fescue based mixtures should be avoided because fescue is invasive and provides little benefit to wildlife. Native, annual small grains appropriate for the season are preferred and recommended. Where feasible use woody debris and logs from corridor clearing to establish brush piles and downed logs at the edge (just in the woods) of the cleared right- of-way to improve habitat for wildlife. Allowing the corridor area to develop into a brush/scrub habitat would maximize benefits to wildlife. Minimize corridor maintenance and prohibit mowing between April 1 and October 1 to minimize impacts to nesting wildlife. We suggest a maintenance schedule that incorporates a portion of the area (e.g. 1/3) each year instead of the entire project every 3 or 4 years. Additionally, herbicides should not be used in wetland areas or near streams. 3. At stream crossings, restore riparian areas with a native, forested buffer.

This project will ultimately transport 510 million cubic feet a day of natural gas. The project is designed to serve the growing natural gas demand in the southeast, enhance the regional supply basin, and bring natural gas supply to areas that currently have none. The Patriot Project will consist of two components, the Mainline Expansion and the Extension. ETNG is proposing to construct the Patriot Project over a period of 18 months beginning in July 2002 and ending by January 1, 2004. The proposed activities located in North Carolina are only associated with the Extension. The Extension is a new pipeline that, in North Carolina includes: ¦ Construction of a 24-inch-diameter mainline (7.69 miles) in Rockingham County, North Carolina. ¦ Construction of a 16-inch-diameter lateral (0.39 miles) that will extend from the 24-inch- diameter lateral in Rockingham County, North Carolina to the Virginia border (Henry County Power Lateral). ¦ Construction of a meter station at the interconnection between the 24-inch-diameter Extension and the existing Transcontinental Gas Pipeline Corporation (Transco) mainline in Rockingham County, North Carolina (Transco Meter Station). Notwithstanding the Federal Energy Regulatory Commission's (FERC) jurisdiction over this Project, and without waiving the preemptive rights of such jurisdiction, ETNG submits this application to the U.S. Army Corps of Engineers (the Corps) Wilmington District and the State of North Carolina. This application is submitted in compliance with Section 404 of the Clean Water Act and Section 10 of the Rivers and Harbors Act of 1899 for activities affecting Waters of the United States and Navigable Waters, respectively, and conforms to permit requirements for the Section 401 1 r4 W O i , C w O ld Section 1 Project Description Certification for the State of North Carolina. The information included herein is provided for the sole purpose of obtaining Section 404 Permits and Section 401 Certification for those activities associated with the Patriot Project located in the State of North Carolina. 1.2 Purpose and Need The Patriot Project is a $289 million project designed to help meet the natural gas growth in the region and to provide additional natural gas supply, supply diversity, transportation, and competition to the Southeast. It will initially carry 130,000 decatherms (dth) per day of natural gas with an ultimate delivery capacity of 510,000 dth per day. The Patriot Project is required to meet growth in the natural gas local distribution market and to provide resources to meet the increased demand for natural gas-fired electric generation. According to the Energy Information Administration (EIA) forecasts, total energy consumption in the United States is projected to increase from 96.1 quadrillion British thermal units (Btu) to 127.0 quadrillion Btu between 1999 and 2020, an average annual increase of 1.3 percent.' United States demand for natural gas is projected to grow by an average 2.3 percent per year through 2020, and demand for electricity by 1.8 percent per year. The share of natural gas use for electricity generation is projected to increase from 16 percent in 1999 to 36 percent in 2020. Rising demand for natural gas by electricity generators accounts for 57 percent of the increase in natural gas demand. Projected growth in natural gas consumption will require expansion of pipeline capacity to provide access to new supplies and to serve expanding markets. Expansion of pipeline capacity is expected to occur at an average rate of 1.0 percent per year. Total energy consumption for the region that encompasses ETNG's service territory is expected to increase from 1.84 quadrillion Btu to 3.59 quadrillion Btu between 1999 and 2020, an average annual increase of 3.2 percent2.

The facilities in North Carolina are depicted on excerpts of United States Geological Survey (USGS) topographic maps located in Appendix A. The Extension will be installed over a period of 18 months and will affect a total of approximately 108.08 acres of land in North Carolina during construction as shown in Table 1-2. This includes land for a nominal 75- to 100-foot-wide construction right-of-way (ROW) (consisting of 50 feet of permanent and 25 to 50 feet of temporary ROW) for the new pipeline. The 100-foot-wide construction ROW will allow for topsoil segregation in cultivated fields and improved pasture, mild 4 Section 1 Project Description side slope construction (three to seven percent slope), and rock storage. The construction ROW will be reduced to 75 feet in wetlands, and where appropriate, to minimize impact on forested and residential areas. To allow for staging of equipment and materials for the pipeline, additional temporary work space will be required for crossings of railroads, and major roads and waterbodies. Additional temporary work space is tabulated in Appendix B. In addition, ETNG will use approximately five temporary access roads totaling about 1.5 miles as listed on Table 1-3. Access to the construction ROW will be from state and county roads, and from temporary use of private roads listed. Minor upgrading of these existing, non-paved roads may be required to support construction equipment. This may include blading the road surface, culvert replacement, and tree trimming. Materials and equipment will be maintained in contractor/pipeyards near the pipeline. Figures 1-2 and 1-3 show the typical ROW configuration for the pipeline on new ROW and adjacent to powerline rights-of-way, respectively. The new pipeline will be installed 15 feet from the edge of the new permanent 50-foot-wide ROW. The temporary ROW will generally be distributed with 20 feet on the spoil side and 30 feet on the working side of the permanent ROW. 1.3.1 Land Use The 108.08 acres of land in North Carolina that will be affected by construction of the laterals includes 102.47 acres for the Extension, 5.41 acres for the Henry County Power Lateral, and 0.2 acres for the Transco Meter Station. The new permanent ROW for the operation of the project will affect approximately 46.6 acres of land on the Extension and 2.36 acres of land on the Henry County Power lateral. The Transco Meter Station will be installed adjacent to the existing Transco ROW at its intersection with Segment 4 of the Extension and will permanently affect 0.2 acre of land. A receiver will be located in the Transco Meter Station. On the Henry County Power Lateral, the launcher will be at MP 54+12.5 on Segment 4. 5 0 Q) 0 a 0 z a 0 0 cfl c0 0 0 0 cV w O U Q i- I U W zzzzD O I- n tZ 20' 1 15' 35' 1 30' 3 o f I 1 01 o No OI~ I z Ld OIh z O 0 Q- n w f Q ?I a ° ? w j w of W - Df(n w a- V) °-? w o of li W O 0 of o a W W OI li o w w v> w1:2 ?

Following completion of construction, 48.96 acres of land will be retained for the new permanent 50-foot-wide ROW (or easement) for operation of the new facilities. Based on consultations with landowners, there are no properties that are currently used for timber production or tree farms. About 2.1 miles (26%) of the facilities in North Carolina (Segment 4, between MPs S4+7.8 and 9.9), will be constructed adjacent to existing powerline rights-of-way. 1.3.2 Stormwater Two areas of impervious surface will be constructed on the Extension for the Transco Meter Station and a mainline valve along the Extension. The Transco Meter Station will be installed on a 0.2-acre site adjacent to the intersection of Segment 4 and the Transco mainline. The mainline valve will be installed along the Extension on a 0.1-acre valve site at the intersection of the Henry County Power Lateral and the Extension at MP 54+12.5 on Segment 4. The mainline valve and meter station will be installed within the new easement. Construction of the Transco Meter station will also include construction of a new access road. An existing road will be extended by 1,879 feet to the new meter station to provide access. This will result in 0.50 acres of new impervious surface. The access road to the mainline valve is currently an existing road. No wetland or waterbodies are impacted as a result of these facilities. Based on USGS Quadrangles, no waterbodies are within 2,000 feet of the mainline valve and Martin Creek and a tributary to Martin Creek are about 400 feet from the meter station and the new access road. ETNG have reduced the impacts by the following: ¦ Avoiding wetlands and waterbodies; ¦ Reducing the width of the road from 15-feet to 12-feet; ¦ Reducing the effective width of the road by more closely following existing contours; 8 Section 1 Project Description ¦ Limiting the depth of gravel fill to 1-foot, and using geotextile fabric to stabilize the road base; and ¦ Reducing the area of gravel surface within the fenced area of the meter station and valve site. It is anticipated that no new concentrated flow will be discharged to tributaries near the valve site and meter station. Runoff would travel from the valve site and meter station in sheet, shallow and non-concentrated flow for about 2,000 feet and 400 feet through existing vegetated lands to the nearest waterbody, respectively. Based on experience, ETNG has determined that due to the small area of impact and the existing surrounding topography and cover types, stormwater quality controls would not be required in order to prevent an unreasonable adverse impact to the receiving waters. The adjacent vegetated areas provides adequate stormwater quality controls to prevent an unreasonable adverse impact to the receiving waters. As a result of infrequent use, the roads will not be degraded from use and will retain the crownslope and proper drainage, and will require little ongoing grading and maintenance, thereby reducing the amount of sediment included in the run-off. The permanent access roads, meter station, and valve sites will be constructed on the same inspection and monitoring programs as the pipeline corridor. 1.4 Construction Procedures 1.4.1 Standard Pipeline Construction and Restoration Procedures The Patriot Project will be designed, constructed, and operated in accordance with applicable federal regulations and guidelines, including: ¦ United States Department of Transportation (DOT) regulations in 49 Code of Federal Regulations (CFR) Part 192 - Transportation of Natural Gas and Other Gas by Pipeline: Minimum Federal Safety Standards; 9 Section 1 Proiect Description ¦ 18 CFR Part 2.69 - Guidelines to be Followed by Natural Gas Pipeline Companies in the Planning, Clearing and Maintenance of Rights-of-Way; and ¦ ETNG's Erosion and Sedimentation Control Plan (E&SC Plan), included in Appendix C, which incorporates the FERC's Upland Erosion Control, Revegetation, and Maintenance Plan (December 1994) (Plan) and Wetland and Waterbody Construction and Mitigation Procedures (December 1994) (Procedures). Conventional overland pipeline construction in a rural environment proceeds as a moving assembly line, i.e., a construction spread. These activities are described in Section 3 of ETNG's E&SC Plan (Appendix Q. The entire construction sequence is typically completed in about 160 to 180 days (five to six months), depending on the length of the pipeline under construction. ETNG will employ at least one environmental inspector for each construction spread during active construction and restoration. The environmental inspector will be responsible for ensuring compliance with the requirements of the E&SC Plan, the construction drawings, the environmental conditions of the FERC certificate, proposed mitigation measures, and other federal or state environmental permits and approvals. The specific responsibilities of the environmental inspector are described in Section 2.1 of the E&SC Plan. In addition, ETNG will conduct environmental training for both company and contractor personnel whose activities will impact the environment during pipeline construction as described in Section 2.2 of the E&SC Plan. 1.4.2 Specialized Construction Procedures Specialized construction procedures will be used for construction activities in rugged terrain, in agricultural and residential areas, at road crossings, and for waterbody and wetland crossings as described in Sections 4 through 6 of ETNG's E&SC Plan. 10 z 0 H H W F A d W z ?a Wa a? ?1 a U U ti O O a a w A C) U M M O CIA _; O c O w a?+w„ CA O N Np W _ ?+ ? ? p p p p Q\ N O .r p .

This section discusses alternatives considered during the selection of the proposed route for the Extension. It consists of four sections: the No Action/No Build Alternative, Pipeline System Alternatives, Alternative Routes Considered, and Route Realignments. 2.2 No Action/No Build Alternative The Extension (i.e., Line 3600) is required to serve customer loads in Virginia and North Carolina. The Patriot Project is nearly fully subscribed. Although Transco could provide the proposed service, it could not provide that service without construction of similar pipeline facilities into southwestern Virginia and North Carolina. While other fuels could be used to serve these markets, the use of oil, coal, or nuclear fuels has intrinsic environmental disadvantages when compared to natural gas. These disadvantages include the degradation of air quality and/or the potential for spills or leaks. The use of solar, geothermal, or other alternative energy sources have not been developed to the point where they are viable for powering large electric generation plants and could not serve the purpose of the Patriot Project. 2.3 Pipeline System Alternatives System alternatives are those alternatives that could replace all or part of the proposed project by making use of existing natural gas pipeline facilities to serve potential customers. Although a system alternative could replace all or part of the proposed project, modifications or additions to the existing pipeline system, or an entirely new system, would be required to increase its capacity to carry the proposed project's natural gas volumes. While these modifications or additions could result in environmental impacts, these impacts may be less than, similar to, or greater than those associated 14 Section 2 Alternatives with construction of the proposed project. The Extension (i.e., Line 3600) is required to serve customer loads in Virginia and North Carolina. 2.4 Alternative Routes Considered A number of route options were investigated in development of the proposed route for the Extension. The proposed route was deemed to be most favorable from environmental, landowner, economic, and customer service point of view. 2.4.1 General The identification of the proposed route for the Extension involved several steps. The first was map review of the area between the ETNG Line 3300 mainline and Eden, North Carolina. Because the purpose of the Patriot Project is to provide natural gas service to southwestern Virginia and North Carolina, alternative routes between Knoxville, Tennessee through North Carolina to Eden were eliminated. Also eliminated were those alternative routes that would require crossing the Appalachian Mountains between Line 3300 and Eden, or those that began on Line 3300 between Knoxville, Tennessee and Wytheville, Virginia. Once a corridor beginning in the vicinity of Wytheville and ending in the vicinity of Eden was identified, the analysis focused on the following considerations: ¦ Use of existing pipeline, electric power transmission, road or utility corridors for siting of the pipeline; ¦ Avoidance of designated land uses (National Forest land, population centers, abandoned mines, historic landmarks, cemeteries, documented cultural sites, hazardous waste sites, landfills, etc.); ¦ Avoidance of rock outcrops and severe terrain (cliffs, etc.); ¦ Minimizing length of crossing of wetland complexes and designated wildlife habitats (Wildlife Management Areas, designated rare, endangered, and threatened species habitats); ¦ Minimizing the number of waterbody crossings; 15 Section 2 Alternatives ¦ Minimizing overall length of side slope crossings; ¦ Minimizing impacts on landowner property; and ¦ Selecting the best crossing location for features that could not be avoided (Blue Ridge Parkway, parks or trails, residential subdivisions or trailer parks, commercial/retail areas, and planned highway, housing or other commercial/industrial developments). The routing analysis also considered locating the new pipeline in proximity to areas interested in obtaining natural gas supplies. Existing Pipeline Rights-of-Way There are no existing pipeline rights-of-way between the ETNG mainline near Wytheville, Virginia and the Transco mainline near Eden, North Carolina. 2.4.2 Eden Alternative The Eden Alternative was the original route studied by ETNG between MP S4+9.7 and MP S4+10.9. The following table summarizes the characteristics of the Eden Alternative and the corresponding segment of the proposed route. The Eden Alternative and the corresponding segment of the proposed route would cross the same roads and streams. The Eden Alternative would be about 0.2 mile shorter than the corresponding segment of the proposed route; however, the Eden Alternative would be adjacent to a trailer park that was not depicted on the USGS maps during the initial planning of the project. Although the Eden Alternative is shorter than the corresponding segment of the proposed route it was rejected because of the potential impacts to the residents of the mobile home park. 16 Section 2 Alternatives Comparison of the Eden Alternative with the Corresponding Segment of the Proposed Route in Rockingham County, North Carolina Environmental Factor Proposed Route Eden Alternative Total Length (miles) 1.2 1.0 CROW Land Requirements 14.5 12.1 (acres) Perennial Waterbody 1 1 Crossings (number) Forest affected by 11.4 6.9 construction (acres) Residences within 50' of the 0 18 CROW (number) 2.5 Route Realignments Although ETNG considered and in most cases were able to accommodate landowner requests for realignment during the survey phase for the Extension, ETNG continues to work with individual landowners to address specific concerns on their properties. Any minor realignments will take into account environmental, engineering, and property issues and will be filed with when finalized with the landowners. 17 Section 3 Affected Waters of the United States ETNG has or is in the process of performing a route survey to collect wetland, waterbody, threatened and endangered species, and cultural resource information. 3.1 Wetlands Wetlands are defined by the Corps as areas that are inundated or saturated by surface water or groundwater at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions, including swamps, marshes, bogs, and bottomlands. Wetlands along the proposed route were identified by field delineation by wetland scientists. The purpose of the wetland delineation effort was to identify all wetland boundaries that are affected by the pipeline construction activities. 3. 1.1 Existing Wetland Resources Initial determination of potential wetland areas was determined through review of the National Wetland Inventory (NWI) maps. Field wetland delineations were conducted during the winter and spring of 2001. Wetland boundaries were delineated in accordance with the Corps 1987 Wetland Delineation Manual (Environmental Laboratory 1987). The Corps Field Data Forms are located in the Wetland Delineation Report found in Appendix D. A total of 4.42 acres of wetlands will be temporarily impacted by the construction of the pipeline in North Carolina. Of that amount 3.36 acres of forested wetlands will be temporarily impacted during construction. A total of 2.69 acres of wetlands will be permanently altered by the operation of the pipeline; i.e., forested wetlands will be converted to scrub/shrub or emergent wetlands during operation of the pipeline. Furthermore, no wetlands will be affected by the construction or operation of aboveground facilities. Table 3-1 presents the location, classification, length, and construction 18 Section 3 Affected Waters of the United States and operation impacts of the wetlands crossed by the Extension. Descriptions of wetland cover types are summarized in Appendix D. 3.2 Surface Water Resources 3.2.1 Waterbodies Crossed By the Pipeline Waterbodies crossed by the Project were identified during field surveys. Waterbody crossing widths and depths were measured or estimated in the field. Water quality classifications were determined using the applicable state regulations (North Carolina 15A NCAC 2B.0300). The fishery types were determined based on designated water quality classifications and consultation with state and federal resource management agencies. Table 3-2 lists the waterbodies crossed by each project facility and includes the milepost, the state water quality designation and fishery type, and crossing width for each waterbody. Additional information on fishery resources is presented in Section 3.3. Line 3600 will cross nine waterbodies in North Carolina, which are located in the Roanoke River Basin. Of these waterbodies, seven were classified as perennial. Based on the existing stream width information, there are five minor waterbody crossings (less than 10 feet wide), one intermediate waterbody crossings (10 to 100 feet wide), and one major waterbody crossing (over 100 feet wide), i.e., the Smith River on Segment 4 at milepost [MP] 54+8.02. There was no access to the survey corridor to two of the surface waterbodies. Waterbodies will not be directly affected by construction of any of the aboveground facilities. 3.2.2 Navigable Waters - Section 10 As defined by the Corps, navigable waters are those waters that are subject to the ebb and flow of the tide shoreward to the mean high water mark, and/or are presently used, or have been used in the past, or may be susceptible to use for transport of interstate or foreign commerce. The Project does not cross any navigable waters in North Carolina. 19 Section 3 Affected Waters of the United States 3.2.3 Other Surface Water Designations North Carolina has surface water designations for impaired waters (303d list), waterbodies that contain threatened or endangered species or critical habitat, and waterbodies that have steep, eroding banks. No waterbodies crossed by the Extension have been classified as having steep, eroding banks. Waterbodies that contain federal and state protected species are discussed in the North Carolina, Endangered and Threatened Species Report located in Appendix E. Information on contaminated sediments was obtained from the National Sediment Inventory database, which is maintained by the EPA (http://www.epa.gov/OSTBASINS/download.htm). These data are useful as a screening-level assessment of sediment quality but have no regulatory consequence. The EPA database identifies the locations of discrete samples where sediments were tested and classified as polluted, but does not classify river reaches as contaminated. The database was initially searched for any contaminated sediment samples within one mile of the existing and proposed pipeline facilities. These sample sites were then examined in detail to evaluate the potential project impact. Based on this information, the project does not cross any waterbodies known to contain contaminated sediments. 3.3 Fisheries The Extension, which begins in southwest Virginia, extends into north-central North Carolina. The waterbodies crossed are in the Dan River watershed. Many of these streams have relatively slow currents, and runs and riffles are infrequent. Substrates tend to be chiefly sand, silt, and clay. Gravel and rubble are found infrequently (Rohde et al. 1994). In general, these streams are somewhat turbid for several months each year due to soil erosion caused by agricultural and silvicultural activities. The fish species that inhabit these streams are generally tolerant of harsh conditions, such as high turbidity levels and occasional periods of low dissolved oxygen levels. 20 Section 3 Affected Waters of the United States 3.3.1 Representative Fisheries in the Project Area Table 3-2 lists the waterbodies crossed by the proposed project and identifies the water quality classification/fishery type of each of the waterbodies. Waterbodies in the project area are not used for commercial fishing. No essential fish habitat under the jurisdiction of the National Marine Fisheries Service occurs in the vicinity of the project. There are no anadromous, catadromous, coastal, or estuarine fisheries at the specific waterbody crossings along the project. 3.4 Unique, Sensitive, or Protected Communities ETNG reviewed information available from the FWS and NCDENR, to determine if the project crosses areas that are designated as unique, significant, or protected. In North Carolina, Segment 4 of the Extension, crosses the locally Significant Natural Heritage Area (SNHA) - City Park Smith River Slopes in Rockingham County (NCDENR 2001a). The pipeline would cross about 600 feet of this area adjacent to a powerline (NCDENR 2001a) near MP S4+7.8 on the west side of the Smith River. The NCDENR and the NCWRC identified the Roundhouse Road Forest SNHA and Leaksville Loam Forest SNHA as occurring within 1 mile of the Extension (NCDENR 2001a; NCWRC 2001a). The NCWRC also identified Fitzgerald Woodland and Widemouth Creek Conglomerate Exposure SNHAs near the Extension (NCWRC 2001a). None of these natural heritage areas will be crossed by the Extension. 3.5 Endangered and Threatened Species ETNG has consulted with both state and federal agencies regarding endangered and threatened species. ETNG prepared and submitted the Endangered and Threatened species reports to the U.S. Fish and Wildlife Service, Raleigh office, NCDENR, and NCWRC, and received concurrence with the proposed endangered and threatened species surveys methodology and timeframe. Surveys for 21 Section 3 Affected Waters of the United States these species are currently underway. For more information, please see the North Carolina Endangered and Threatened Species Report (Appendix E). The NCDENR (2001a) and the NCWRC (North Carolina Wildlife Resources Commission) (2001a) commented that the Dan River contains populations of rare aquatic species, and is considered one of six high priority areas for long term conservation. Although the Extension passes through the Dan River watershed it does not actually cross or parallel the river or any of its direct tributaries. The NCWRC recommended that should the pipeline parallel any stream, the edge of the construction area should be located a minimum distance of 100 feet from any perennial stream bank. In addition, they recommended maintaining a 50-foot buffer along intermittent streams to minimize impact on aquatic species. Based on field surveys conducted to date, the Extension and the Henry County Power Lateral will not parallel any perennial or intermittent streams in North Carolina. 3.6 Cultural Resources ETNG has consulted with the North Carolina State Historic Preservation Office (SHPO) as well as Native American groups. ETNG completed a cultural resource survey for the proposed Extension corridor. The results of the survey were presented in a report provided to the SHPO. The cultural resource surveys were conducted within a 200-foot-wide corridor in compliance with all SHPO guidelines. In some locations, landowners did not grant access. These no-access areas are shown on the maps and alignment sheets attached to the Patriot Project application. When permission is obtained, these portions of the corridor will be surveyed and the reports filed with the Commission. The cultural resources surveys were completed for the Extension, the Henry County Power Lateral, and about 1.1 miles of access roads in Rockingham County, North Carolina (Reid, 2001a). Surveys to be completed include one 0.85 mile segment where access was denied and backhoe trenching of the Smith River crossing near MP S4+8.0 to examine the potential for deeply buried cultural deposits in floodplain settings as requested by the North Carolina SHPO. 22 Section 3 Affected Waters of the United States Six previously recorded archaeological sites are located within 0.6 mile of the proposed project area. None of these cultural resources will be either directly or indirectly impacted by the proposed pipeline construction. The archaeological field surveys of the proposed route identified three archaeological resources. These resources comprise one dilapidated barn, one historic artifact scatter, and one isolated find. None of these resources were recommended as eligible for the NRHP. The architectural inventory file search identified 28 previously recorded architectural resources located within 0.6 mile of the proposed pipeline corridor. In addition, one architectural resource was recorded during the architectural field survey. This resource is a plank barn with poor architectural integrity and was not recommended as eligible for the NRBP due to its poor condition and the ubiquity of these types of structures in the project area. 3.6.1 Unanticipated Discovery Plan ETNG has developed an Unanticipated Discovery Plan in the event that any potentially eligible historic or prehistoric cultural resources are identified during project construction. A copy of this plan is included in Appendix G. 23 ^ R C a '$$ °e 3 z z z zz z z z z z z z ? ?f z ...333 W W z z 0 "" O 3 O v u m l v b ?

ETNG has made an effort to avoid and minimize the extent of impacts to wetlands as much as is possible by: 1) utilizing an existing utility ROW, 2) implementing an Erosion and Sedimentation Control Plan, and 3) proposing to implement minimization techniques such as seasonal timing, special equipment, and limiting workspace as required during construction. ETNG's approach will result in a project with only minor permanent and temporary impacts to wetlands and water related resources during construction and minor conversion of forested wetlands to scrub/shrub or emergent wetlands. 4.1 Wetland Impacts and Mitigation The proposed Extension will traverse approximately 0.49 miles of wetlands within the State of North Carolina along the proposed route of the new pipeline. A total of 4.42 acres of wetlands will be temporarily affected by the construction of the pipeline and 2.69 acres of wetlands will be permanently altered by the operation of the pipeline. The primary impact to wetlands, other than temporary soil disturbance and temporary alteration of hydrology in the area, will be some permanent cover type conversion from forested wetland to scrub-shrub and emergent wetland types. To minimize impacts, ETNG's construction ROW will be reduced from 100 feet wide to 75 feet wide in wetlands. A detailed discussion of wetland resources affected by the Patriot Project are presented in the Project's North Carolina Wetland Delineation Report found in Appendix D. Mitigation and construction and restoration activities in wetlands will be in accordance with ETNG's E&SC Plan (Appendix Q. The procedures described in the E&SC Plan have not been approved by the State of North Carolina, to date, but are based upon an integration of guidelines and principles from the FERC, the Corps, the USFWS, the U.S. Department of Agriculture (USDA), and the practical experience of ETNG. All temporary fill material and equipment crossings in wetlands will 26 Section 4 Impacts and Mitigation be removed in their entirety following construction and the area will be restored and stabilized according to ETNG's E&SC Plan and agency recommendations. Access to the construction ROW will be restricted to existing roads to the practicable extent possible. Per regulations of the State of North Carolina, no straw bales will be used during construction. All wetlands will be crossed using an open-cut method as described in Section 6 of the E&SC Plan. For construction of large diameter pipelines, the use of an Horizontal directional drill (HDD) for wetland crossings is not typically employed. HDD will not be employed for wetland crossings for the following reason: ¦ The topography of the crossing - A wetland in a deep ravine may necessitate a 1000-1500 foot HDD due to the geometry constraints of the pipe. In relatively flat areas, a 24-inch pipe will require at least a 1100 foot HDD. That is often not practical; ¦ Additional disturbance - An HDD requires additional workspace for mobilization, drilling mud storage, drilling rig operation, and possible false ROW for the pull-back pipe section; ¦ Aesthetic impacts - An HDD may be required to be in place for months at a time. Visually and audible disturbances will be realized by adjacent landowners during that time period; ¦ Probability of HDD success - Not all areas have the subsurface geological characteristics that ensure success of an HDD. Subsurface conditions such as gravel or cobble can lower the potential percentage rate of success for a particular HDD; and ¦ Possibility of a frac-out - Fractured subsurface rock or voids can increase the likelihood of a fracture inside the wetland where drilling mud can be forced to the surface. 4.2 Surface Water Impacts and Mitigation To avoid or minimize impacts to waterbodies, ETNG will implement several methods and/or approaches previously accepted by the Corps, State of North Carolina and FERC. These methods are presented in the E&SC Plan located in Appendix C. ETNG will adhere to its E&SC Plan during construction across surface waters, which incorporates the FERC Procedures for protection against 27 Section 4 Impacts and Mitigation erosion and control of sediments. Temporary equipment crossings will be installed across all waterbodies including those crossed by temporary access roads. Where needed to protect water resources, construction within waterbodies will be completed as a distinct and independent construction operation. This will permit the scheduling of crews and equipment to capitalize on favorable weather conditions, expedite construction, and minimize potential sedimentation impacts. Construction crossing procedures vary depending on the nature and size of the waterbody. Waterbodies will be crossed using an open cut or HDD construction procedure as described in Section 5 of the E&SC Plan. ETNG proposes to use an open cut method at all crossings except for the Smith River (S4+8.02). ETNG has included an HDD Contingency Plan (included as part of Appendix C), which would be implemented during any HDD. Use of HDD is dictated by site specific conditions and can be a very complicated procedure and at times add to the potential for environmental impacts. For example, HDD requires welding of pipes at each crossing, introduces the possibility of failed bores due to fractures in the rock and the possibility of bentonite permeating to the surface of waterbodies due to substrate conditions. Geotechnical studies will be conducted to determine the feasibility of an HDD at the Smith River and the reports will be filed with the FERC and the Corps when completed. Restoration of disturbed areas (except for those that employ the HDD) associated with a waterbody crossing will be within 48 hours of the disturbance. All refueling activities and maintenance of equipment will be executed in accordance with ETNG's E&SC Plan and SPCC Plan (Appendix D). Hazardous waste materials, chemicals, fuels, and lubricating oils will not be stored within 100 feet of any waterbody, wetland, or designated watershed area. Disposal of construction waste materials will follow local, state, and federal regulations and will be carried to approved public or private waste disposal sites. ETNG will not use chemicals for hydrostatic testing or for drying the pipeline following the hydrostatic testing. All discharge water will be systematically discharged at a controlled rate, using energy dissipation devices filter bags or similar devices to prevent erosion, streambank scour, 28 Section 4 Impacts and Mitigation suspension of sediments, and excessive stream flows. Section 3 of ETNG's E&SC Plan provides additional detail on hydrostatic testing procedures. 4.3 Fisheries Impacts and Mitigation Impacts to fishery resources during construction can include sedimentation and turbidity, alteration or removal of fish cover, introduction of water pollutants; decrease in dissolved oxygen levels, and entrainment of fish. However, the impact to fisheries should be short-term and minimal. Several studies have confirmed that benthic recolonization by macro invertebrates can be rapid and occurs within 12 hours to several days following instream construction. Low-gradient streams may take longer to recover, and high spring flows are usually required to remove remaining fines from riffle habitats. Increased downstream turbidity will occur during in-stream trenching, backfilling and from other streambank disturbance. ETNG will minimize the discharge of suspended solids from upland sources, including runoff from trench spoil and disturbed and exposed soils adjacent to streams, by the installation of sediment barriers, and the construction of temporary berms. Construction activities should not reduce the carrying capacity of the stream or result in permanent alteration of existing habitat. The open cut and HDD crossing techniques do not obstruct fish movement. However, normal movements of fish and other aquatic species may be temporarily altered during the crossing. The length of stream affected by construction, between 75 and 100 feet of streambed, is significantly minor in contrast to the undisturbed resource available in reaches adjacent to the construction site. The duration of the disturbance should be short-term, often less than 24 hours, and restoration will typically occur immediately after pipe installation, further reducing the impact to fish and invertebrates. Hydrostatic test water withdrawal and discharge activities are not expected to impact fishery resources. Withdrawal intake hoses will be equipped with intake screen devices that will eliminate the entrainment of small fish during water withdrawal. All discharge water will be in compliance 29 Section 4 Impacts and Mitigation with applicable regulatory permit conditions and will be controlled to prevent sedimentation, flooding, or the introduction of foreign or toxic substances in the waterbody. The NCWRC commented that it has concerns about direct impacts to aquatic species habitat resulting from construction and maintenance of the pipeline (NCWRC 2001). ETNG's E&SCP is designed to minimize these impacts. Only a limited amount of instream and shoreline cover will be altered at the proposed waterbody crossing locations. Streambank vegetation, in-stream woody debris, large rocks, and undercut banks may be removed during construction. The NCWRC recommends that disturbed areas be replanted with native species beneficial to wildlife. ETNG will coordinate with the NCWRC and other state agencies to determine the best seed mixes for a given segment of the project, and other plantings, as necessary. 4.4 Endangered and Threatened Species Impacts and Mitigation ETNG has prepared an Endangered and Threatened Species Report using the results of database searches and consultation with the USFWS, Raleigh office, NCDENR, and the NCWRC. This report identifies the federal and state listed species that potentially occur in the project area and proposed field surveys. The report was provided to the USFWS, NCDENR, and the NCWRC in August 2001 for their review and comment and is located in Appendix E. ETNG has received agency concurrence for the proposed survey methodology and field survey time frame and is currently conducting surveys in areas identified along the ROW. Specific mitigation plans for species that could be potentially affected during construction will be developed pending the outcome of the surveys. Prior to construction, an environmental training program for all personnel involved in the project will be developed for the project. The training will specifically include a review of federal and state protected species that may be encountered along the project in North Carolina. The training program will include at a minimum, a description of the species and habitat requirements and will outline the procedures to be followed in the event that a protected species is discovered. 30 Section 4 Impacts and Mitigation 4.5 Operation and Maintenance The project will be operated and maintained by ETNG. ETNG will continue to operate the facilities in the same manner as it currently operates and maintains its major interstate pipeline facilities and in accordance with the requirements of the DOT. The pipelines will be patrolled on a routine basis from the air and on the ground, and maintenance will be handled by personnel well qualified to perform both emergency and routine maintenance on interstate natural gas pipeline facilities. The Patriot Project facilities will be operated and maintained in a manner such that pipeline integrity is maintained in the interest of assuring that a safe, continuous supply of natural gas reaches its ultimate destination. Routine patrols will provide information on construction activities near the pipeline, erosion, exposed pipe, population density, possible encroachment, and any other potential problems that may affect the pipeline. In addition, all permanent erosion control devices installed during construction will be inspected to assure that they are functioning properly. Particular attention will be given to: ¦ Serious erosion and washouts along the ROW; ¦ Water control devices such as diversions; ¦ Condition of banks at stream and river crossings; ¦ Fallen timber or other threats to the pipeline; ¦ Shrubs and other vegetation planted during construction; and ¦ Any other conditions that could affect safe operation of the pipeline. Problems identified during the patrols will be corrected, as needed. Other maintenance functions will include periodic seasonal mowing of the ROW in accordance with the vegetative maintenance restrictions outlined in ETNG's E&SC Plan and the FERC Plan and Procedures and maintaining a supply of emergency pipe, leak repair clamps, sleeves, and other equipment needed for repair activities. ETNG will not use herbicides or pesticides within 100 feet of a wetland or waterbody unless approved by appropriate state and local agencies. 31 Section 5 References Clifford, Laura. 2001.

INTRODUCTION 1.1 Purpose of this Plan This Erosion and Sedimentation Control Plan (Plan) has been prepared for use by the Company and its contractors as a guidance manual for minimizing erosion of disturbed soils and transportation of sediments off the right-of--way (ROW) and into sensitive resources (wetlands, streams, and residential areas) during natural gas pipeline construction. The procedures developed in this Plan, which represent the Company's best management practices, are designed to accommodate varying field conditions while maintaining rigid minimum standards for the protection of environmentally sensitive areas. This Plan is designed to provide specifications for the installation and implementation of soil erosion and sediment control measures while permitting adequate flexibility to use the most appropriate measures based on site-specific conditions. The intent of this Plan is to provide general information on the pipeline construction process and to describe specific measures that will be employed during and following construction to minimize impacts to the environment along the pipeline ROW. The goal of this Plan is to preserve the integrity of environmentally sensitive areas and to maintain existing water quality by implementing the following objectives: • Minimize the extent and duration of disturbance; • Protect exposed soil by diverting runoff to stabilized areas; • Install temporary and permanent erosion control measures; and • Establish an effective inspection and maintenance program. 1.2 Guidelines and Requirements The measures described in this Plan have been developed based on guidelines from the Federal Energy Regulatory Commission (FERC), United States Army Corps of Engineers (COE), the United States Fish and Wildlife Service (USF&W), the United States Department of Agriculture, and the Natural Resource Conservation Service, as well as from the Company's significant experience and practical knowledge of pipeline construction and effective environmental protection measures. Lessons and insights gained during pipeline construction projects along the Company's pipeline system and comments from agency representatives are also incorporated into this Plan. Any deviation from the placement of the structures specified in the construction drawings, or changes in the design of control measures as set forth in this Plan, must be approved by the Company's Environmental Protection Department and must have the concurrence from the appropriate permitting agency. Introduction Page 1-1 S.%datalENVPROTIE&SPla=E&SPlan.doc Pursuant to changes in the FERC regulations, interstate pipeline companies are now required to comply with the FERC's Upland Erosion Control, Revegetation, and Maintenance Plan and the FERC's Wetland and Waterbody Construction and Mitigation Procedures (Plan and Procedures), unless approval to deviate from the Plan and Procedures is received from the appropriate state agency. The following identifies the differences between this Plan and the FERC's Plan and Procedures as well as the reasons behind the differences: 1. FERC Plan (Section VI.C.1 and VI.C.3): Perform compaction testing in residential areas disturbed by construction activities and perform appropriate soil compaction mitigation in severely compacted residential areas. This Plan: Compaction testing and mitigation are not required in residential areas. Reason to Deviate: This Plan requires that topsoil either be segregated or replaced in residential areas. Topsoil that is segregated or replaced results in little compaction and provides a suitable medium for grass. Most yard areas that are sown in grass do not require deep root penetration. In the event that the grass needs deeper root penetration, the subsequent freeze thaw cycles of the upper portions of the subsoil will provide natural mitigation of any compacted areas of the ROW within 2-3 years. Post-construction monitoring will be conducted during this timeframe as discussed in Section 8.1. 2. FERC Procedures (Section VI.D.5): For all forested wetlands affected: a. Plant native trees to ultimately restore the temporary ROW and the non-maintained portion of the permanent ROW to its preconstruction state; b. Plant native shrub and herbaceous species to revegetate the 30-foot wide portion of the permanent ROW; and c. Consult with the USF&W, EPA, COE, and the appropriate state agency to determine the density for planting the native trees and shrubs. This Plan: All wetlands shall be temporarily revegetated along the ROW with annual ryegrass for short-term erosion control, allowing for subsequent natural revegetation with native tree species. Should a permitting agency identify the need to develop a forested wetland revegetation plan, the Company will do so on a site-specific basis and defer to the regional agencies for consultation and recommendations. Reason to Deviate: The subsequent reestablishment of native species would be a natural process developing from the seedbank and rootstock present in the wetland topsoil. The need to plant trees and shrubs within disturbed, forested wetlands is not necessary or cost effective. A planting program would require continual monitoring and occasional replacement of the planting materials as necessary. At present, the post-construction vegetation maintenance guidelines set forth in the FERC Procedures and adopted in this Plan, is not only conducive for the quick establishment of a scrub-shrub wetland cover type, but also allows for the redevelopment of a forested component along the edges of the disturbed ROW. Introduction Page 1-2 S. idata1ENVPR071E&.S PlanstE&S Plan.doc 3. FERC Procedures (Section V.B.4.a): For all intermediate waterbody crossings, spoil shall be placed at least 10 feet from the water's edge. This Plan: Spoil may be sidecast into intermediate waterbodies greater than 30 feet in width. Reason to Deviate: Allowing sidecasting minimizes stream disturbance and earth disturbance as well as enhances restoration efforts, as discussed below: a. The backhoe to be used for excavation of the waterbody from the top of bank does not have a boom with a long enough reach. The equipment would need to operate in the waterbody if it is wider than 30 feet and tracking equipment in and out of the waterbody would cause more impacts than sidecasting spoil; b. If the high bank has to be graded to allow an approach to the waterbody, more stream damage could occur not only from the initial pipeline installation but from the subsequent high bank restoration efforts as well; and c. If sidecasting is not allowed, not only could the issues described in a) and b) occur, the size of the spoil storage area would need to increase to accommodate all of the excavated spoil. Workspace areas, which typically contain the spoil storage area and are located 50 feet or more from the waterbody's edge, would have to be large enough and sufficiently cleared to accommodate the spoil storage as well as the movement of tracked equipment to and from the waterbody. 1.3 Surveys, Permits, and Notifications The Company shall perform the required environmental field surveys and acquire the necessary environmental permits prior to start of construction of the project. The Company shall notify the appropriate federal and state agencies prior to, during, and/or subsequent to the construction of the project, as identified in the Clearance Package/ Permit Book. - 1.4 Inquiries inquiries regarding this Plan should be addressed to the Supervising Engineer, Environmental Protection Department; Company name as shown on the front cover, P.O. Box 1642; Houston, Texas 77056. For field conditions requiring an immediate response, contact the Area Manager at the address shown on the front cover. Introduction Page 1-3 S WatatENVPR071E&SPlanstE&SPlan.doc 2. SUPERVISION AND INSPECTION To effectively mitigate project-related impacts, the Plan must be properly implemented in the field. Quick and appropriate decisions in the field regarding critical issues such as stream and wetland crossings, placement of erosion controls, trench dewatering, spoil containment, and other construction related items are essential. To ensure that the Plan is properly implemented, at least one Environmental Inspector (EI) will be designated by the Company for each construction spread during active construction or restoration. The El will have peer status with all other activity inspectors and will report directly to the Resident Engineer/ Chief Inspector who has overall authority on the construction spread. On smaller projects, the EI role may be carried out by the Resident Engineer/ Chief Inspector or a Craft Inspector, as designated by the Company. The EI will have the authority to stop activities that violate the environmental conditions of the FERC certificate (if applicable) or other permits, and to order corrective action. 2.1 Responsibilities of the Environmental Inspector At a minimum, the EI shall be responsible for: I . Ensuring compliance with the requirements of this Plan, the construction drawings, the environmental conditions of the FERC certificate (if applicable), proposed mitigation measures, and other federal or state environmental permits and approvals; 2. Verifying that the limits of authorized construction work areas and locations of access roads are properly marked before clearing; 3. Verifying the location of drainage and irrigation systems; _ 4. Identifying stabilization needs in all areas; 5. Identifying locations for dewatering structures and interceptor dikes to ensure they will not direct water into known cultural resources sites or locations of sensitive resources; 6. 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. The design of the discharge shall be changed by the EI to prevent reoccurrence; 7. Testing subsoil and topsoil in agricultural areas to measure compaction and determine the need for corrective action; 8. Advising the Chief Inspector when conditions (such as wet weather) make it advisable to restrict construction activities in agricultural areas; 9. Ensuring restoration of contours and topsoil; 10. Pre-approving imported soils for use in agricultural and residential areas; 11. Ensuring that temporary erosion controls are properly installed and maintained, daily if necessary, Supervision and Inspection Page 2-1 S. ldatatENVPROTIE&SPlanslE&SPlan.doc 12. Inspecting temporary erosion control measures at least: a. On a daily basis in areas of active construction or equipment operation; 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; 13. Ensuring the repair of all ineffective temporary erosion control measures within 24 hours of identification; 14. Ensuring that the Contractor implements and complies with the Company's Spill Prevention Control and Countermeasure (SPCC) Plan; and 15. Keeping records of compliance with the environmental conditions of the FERC certificate (if applicable), proposed mitigation measures, and other Federal or state environmental permits during active construction and restoration. 2.2 Environmental Training for Construction If required by the FERC certificate, environmental training will be given to both the Company personnel and contractor personnel whose activities will impact the environment during pipeline construction. The level of training will be commensurate with the type of duties of the personnel. All construction personnel from the chief inspector, EL craft inspectors, contractor job superintendent to loggers, welders, equipment operators, and laborers will be given some form of environmental training. In addition to the EI, all other construction personnel are expected to play an important role in maintaining strict compliance with all permit conditions to protect the environment during. construction. Training will be given prior to the start of construction and throughout the construction process, as needed, and will cover the following issues: • The specifics of this Plan including the SPCC Plan; • Job or activity specific permit requirements; • Company policies and commitments; • Cultural resource procedures and restrictions; • Threatened and endangered species restrictions; and • Any other pertinent information related to the job. Supervision and Inspection Page 2-2 S: IdatatENVPROTIE&SPlanslE&SPlan.doc 3. CONSTRUCTION TECHNIQUES FOR NATURAL GAS PIPELINES 3.1 Typical ROW Requirements Pipeline construction workspace requirements are a function of pipe diameter, equipment size, topography, geological rock formations, location of construction such as at road crossings or river crossings, pipeline crossovers, methods of construction such as boring or open-cut construction, or existing soil conditions encountered during construction. As the diameter of the pipeline being installed increases, so does the depth of trench, excavated spoil material, equipment size, and ultimately the amount of construction work space that will be required to construct the project. All construction activities are restricted to the ROW limits identified on the construction drawings. The U.S. Department of Transportation (DOT) and Occupational Safety and Health Administration (OSHA) have established minimum size and area requirements for worker safety involving construction activities. See Figures 1, 2, and 3 for typical construction ROW widths. Additional construction ROW may be required at specific locations to construct a pipeline including, but not limited to, steep side or vertical slopes, road crossings, crossovers, areas requiring topsoil segregation, and staging areas associated with wetland and waterbody crossings. These locations are shown on the construction drawings. 3.2 Access Roads All access to the construction ROW will be limited to existing roads and minimized in wetlands to the extent practical. Additional access roads to the ROW are required at various points along the project ROW where other road crossings (paved or gravel/state/local roads) do not exist. Examples of types of access used include abandoned town roads, railroad ROWs, powerline service roads, logging roads and farm roads. Improvements to access roads (i.e., grading, placing gravel,-replacing/instailing culverts, and trimming overhanging vegetation) may be required due to the size and nature of the equipment that would utilize the road (Figure 4). 1. Access to the ROW during construction and restoration activities is permitted only by the new or existing access roads identified on the construction drawings. 2. Contractor shall maintain safe conditions at all road crossings and access points during construction and restoration. All access roads will be maintained during construction by grading and the addition of gravel or stone when necessary. 3. Contractor will implement all appropriate erosion and sedimentation control measures for construction/improvement of access roads. 4. Contractor shall ensure that all paved road surfaces utilized during construction are kept free of mud and debris to the extent practical. Construction Techniques Page 3-1 S WatatENVPROM&S PlansTAS Plan.doc 5. If rock access pads are required by the permitting agencies in residential or active agricultural areas, rock shall be placed on nonwoven geotextiie fabric to facilitate rock removal after construction (Figure 5). 3.3 3.4 6. All access roads across a waterbody must use an equipment bridge in accordance with Section 5.2.2. 7. The only access roads, unless otherwise permitted, that can be used in wetlands other than the construction ROW are those existing roads- requiring no modification and no impact on the wetland. 8. Limit construction equipment operating in wetland areas to that needed to clear the ROW, dig the trench, fabricate and install the pipeline, backfill the trench, and restore the ROW. All other construction equipment shall use access roads located in upland areas to the maximum extent practical. Where access roads in upland areas do not provide reasonable access, limit all other construction equipment to one pass through the wetland using the ROW, whenever practical. 9. For access through a saturated wetland, unless otherwise authorized by agency permits, use timber mats or an equivalent (Figure 6). Pipe and Contractor Wareyards Pipe and contractor wareyards are required for storing and staging equipment, pipe, fuel, oil, pipe fabrication, and other construction related materials. The Contractor shall perform the following measures at pipe and contractor wareyards: 1. Strip and segregate topsoil in agricultural lands; 2. Install erosion control structures as directed by the EI, outlined in this Plan, or identified on the construction drawings, and maintain them throughout construction and restoration activities; 3. Implement and comply with the SPCC Plan; and 4. Restore and revegetate all disturbed areas in accordance with the measures outlined in this Plan and as directed by the EI. Off-ROW Disturbance All construction activities are restricted to within the limits identified on the construction drawings. However, in the event that off-ROW disturbance occurs, the following measures will be implemented: 1. The EI will immediately report the occurrence to the Chief Inspector and ROW Agent; 2. The conditions that caused the disturbance will be evaluated by the Chief Inspector and the EI, and they will determine whether work at the location can proceed under those conditions; and Construction Techniques Page 3-2 S %dataIENVPRO?lE&SPlansIE&SPlan.doc 3. If deemed necessary by the Chief Inspector and El, one or more of the following corrective actions will be taken: immediate restoration of the original contours, seeding and mulching of the disturbed area, and/or installation of erosion control devices. The Company's Environmental Protection Department will be notified as soon as practical. 3.5 Construction Sequence Natural gas pipelines are installed using conventional overland buried pipeline construction techniques. These activities are necessary for the installation of a stable, safe, and reliable transmission facility consistent with DOT requirements and regulations. This section provides an overview of the equipment and operations necessary for the installation of a natural gas pipeline, describes potential impacts that may occur from each operation, and identifies the measures that will be implemented to control these potential impacts. This section also discusses in detail the erosion and sediment control techniques that apply to each construction activity including clearing, grading, trenching, lowering-in of pipe, backfilling, and hydrostatic testing. ROW restoration will be addressed in Section 3.6. Installation of the pipeline will typically proceed from one end of the construction spread to the other in an assembly line or "mainline" fashion. The spacing between the individual crews responsible for each interdependent activity is based on anticipated rate of progress. The activities listed below are normally performed in the following sequence: • Survey and Flag the ROW; • Clearing the ROW; • Installing temporary sediment barriers; • Grading the ROW; • Installing temporary interceptor dikes; - • Trenchinglexcavating the trench; • Pipe stringing and bending; • Welding and weld inspection; • Trench dewatering, • Lowering the pipe into the trench; • Backfilling the trench; • Hydrostatic testing of pipe; and • ROW restoration and clean-up. Obstacles to the mainline technique are often encountered and are not considered to be out of the ordinary. These obstacles, which include side hill crossings, rock, wetlands, streams, roads, and residential areas, do not normally interrupt the assembly line flow. 3.5.1 Clearing Clearing operations will include the removal of vegetation within the construction ROW. Various clearing methods will be employed depending on tree size, contour of the land, and the ability of the Construction Techniques Page 3-3 S.•IdataIE1WPROTIE&SPlanslE&SPlan.doc ground to support clearing equipment. Vegetative clearing will either be accomplished by hand or by cutting equipment. The following procedures will be standard practice during clearing: 1. Prior to beginning the removal of vegetation, the limits of clearing will be established and identified in accordance with the construction drawings; 2. All construction activities and ground disturbance will be confined to within the ROW shown on the construction drawings; 3. Clearly mark and protect trees to be saved as per landowner requests or as otherwise required; 4. All brush and trees will be felled into the construction ROW to minimize damage to trees and structures adjacent to the ROW. Trees that inadvertently fall beyond the edge of the ROW will be immediately moved onto the ROW and disturbed areas will be immediately stabilized; 5. Trees will be chipped or cut into lengths identified by the landowner and then stacked at the edge of the ROW or removed; 6. Brush and limbs may be disposed of in one or more of the following ways depending on local restrictions, applicable permits, construction Line List stipulations, and landowner agreements: a. Stockpiled along the edge of the ROW, b. Burned; c. Chipped, spread across the ROW in upland areas, and plowed in; or d. Hauled off site. 7. Existing surface drainage patterns will not be altered by the placement of timber or brush piles at the edge of the construction ROW. 3.5.2 Installing TemporarySedimentBarriers Sediment barriers, which are temporary erosion controls intended to minimize the flow of sediment, shall be installed following vegetative clearing operations. They may be constructed of materials such as silt fence, staked straw bales, sandbags, or an equivalent material as identified by the EI (Figures 7, 8, 9, 10). Hay bales may be used in lieu of straw bales with the following restrictions - hay bales shall not be used for mulching and the Contractor is responsible for their removal and disposal. 1. Install temporary sediment barriers at the base of slopes adjacent to road crossings and at waterbody and wetland crossings in accordance with Sections 5.2A and 6.2.2 respectively. 2. Do not stake or trench in place straw bales used on equipment bridges or on mats across the travel lane. Construction Techniques Page 3-4 S. IdatalENVPROTIE&S PlanstE&S Plan.doc 3. Inspect temporary sediment barriers daily in areas of active construction to ensure proper functioning and maintenance. In other areas, sediment barriers will be inspected and maintained on a weekly basis throughout construction, and within 24 hours following storm events. 4. Maintain all temporary sediment barriers in place until permanent revegetation measures are successful or the upland areas adjacent to wetlands, waterbodies, or roads are stabilized. 5. Remove temporary sediment barriers from an area when it has been successfully restored as specified in Section 8.1. 3.5.3 Grading The construction ROW will be graded as needed to provide a level workspace for safe operation of heavy equipment used in pipeline construction. The following procedures will be standard practice during grading: 3.5.3.1 Topsoil SePregation Topsoil segregation methods will be used in all residential areas and when the construction ROW is wider than 30 feet in annually cultivated or rotated agricultural lands (except pasture), hayfields, and other areas at the landowner's request. a. Prevent the mixing of topsoil with subsoil by stripping topsoil from either the full work area or from the trench line and subsoil storage area (ditch plus spoil side method) as stipulated in the Construction Contract or Line List (Figure 11). b. Segregate at least 12 inches of topsoil in deep soils with more than 12 inches of topsoil. In soils with less than 12 inches of topsoil, make every effort to segregate the entire-topsoil layer. c. For wetlands, segregate the top 12 inches of topsoil within the ditchline, except in areas where standing water or saturated soils are present. Do not use geotextile fabric to segregate topsoil. d. Leave gaps in the topsoil piles for the installation of temporary interceptor dikes to allow water to be diverted off ROW. e. Topsoil replacement (i.e., importation of topsoil) may be used as an alternative to topsoil segregation if approved by the landowner and Chief Inspector f. Never use topsoil for padding, backfill or trench plugs. 3.5.3.2 Thee Slump Removal and Disoosa/ a. Remove tree stumps in upland areas along the entire width of the permanent ROW to allow adequate clearance for the safe operation of vehicles and equipment. Stumps within the temporary ROW will be removed or ground to a suitable height that will allow the safe passage of equipment, as stipulated by the Chief Inspector or EI. Construction Techniques Page 3-5 S IdatalENVPRO71E&SP1ans1E&SPlan.doc b. Dispose of stumps by one of the following methods, pending approval by the Chief Inspector and the landowner, and in accordance with regulatory requirements: • Buried at a Company-approved off-site location (except in wetlands and agricultural areas); • Burned; • Chipped, spread across the ROW in upland areas, and plowed in; or • Ground to grade in wetlands, excess chips will be removed for proper disposal. c. Grading operations and tree stump removal in wetland areas will be conducted in accordance with Section 6.2.1. 3.5.3.3 Rock Disposal Rock (including blast rock) will be disposed of in one or more of the following ways: a. Buried on the ROW or in approved construction work areas either in the ditchline or as fill during grade cut restoration in accordance with the Construction specifications. In cultivated/ agricultural lands, wetlands, and residential areas, rock may only be backfilled to the top of the existing bedrock profile; b. Windrowed per written landowner agreement with the Company; c. Removed and disposed of at a Company-approved site; or d. Used as riprap for stream bank stabilization where allowed by applicable. 3.5.4 Installing TemporarylnterceptorDlkes Temporary interceptor dikes, which are temporary erosion control measures intended to reduce runoff velocity and divert water off the construction ROW, shall be installed following grading operations (Figure 12). Temporary interceptor dikes may be constructed of materials such as compacted soil, silt fence, staked straw bales, or sand bags. Hay bales may be used in lieu of straw bales with the following restrictions - hay bales shall not be used for mulching and the Contractor is responsible for their removal and disposal. 1. Install temporary interceptor dikes at the following spacing: Slope (%) Spacing (feet) <5 No Structure 5-15 300 > 15 - 30 200 > 30 100 Construction Techniques Page 3-6 S: IdataTAWROTIE&S PlanslE&S Plan.doc 2. Direct the outfall of each temporary interceptor dike to a stable, well vegetated area or construct an energy-dissipating device (silt fence, staked straw bales, erosion control fabric) at the end of the interceptor dike. 3. Install temporary interceptor dikes across the entire ROW at all waterbody and wetland crossings, as well as the base of slopes adjacent to roads, when directed by the El. 4. Driveable berms, which are smaller versions of interceptor dikes constructed of compacted soil or sand bags, may be used in place of staked straw bales at the entrances and exits of travel lanes at road crossings, waterbodies, and wetlands. They are installed the width of the travel lane at the start of the equipment crossing and made low enough to allow equipment and other vehicles to pass. Yet, they reduce and divert water runoff from sensitive environmental resources. 5. Inspect temporary interceptor dikes daily in areas of active construction to insure proper functioning and maintenance. In other areas, the interceptor dikes will be inspected and maintained on a weekly basis throughout construction, and within 24 hours following storm events. 3.5.5 Trencbiug The trench centerline will be staked after the construction ROW has been prepared. In general, a trench will be excavated to a depth that will permit burial of the pipe with a minimum of 3 feet of cover (Figure 13). Overland trenching may be accomplished using a conventional backhoe or a rotary wheel-ditching machine. In shale or rocky areas where the use of the wheel-ditching machine is limited, a tractor-drawn ripper will be employed to break and loosen hard substratum material. In areas where rock cannot be ripped, drilling and blasting may be required. A backhoe may then be used to remove rock and soil from the ditch. The following procedures will be standard practice during ditching: 1. Flag drainage tiles damaged during ditching activities for repair; and 2. Place spoil at least 10 feet upgradient from the edge of waterbodies. Spoil will be contained with erosion and sedimentation control devices to prevent spoil materials from transferring into waterbodies and wetlands or off of the ROW. 3.5.5.1 Temnorary 71rencb Plugs Temporary trench plugs are barriers within the ditch that segment the continuous open trench. They typically consist of compacted subsoil or sandbags (soft) placed across the ditch or composed of unexcavated portions of the ditch (hard). Along steep slopes, they serve to reduce erosion and sedimentation in the trench and minimize dewatering problems at the base of slopes where sensitive environments such as waterbodies and wetlands are frequently located. In addition, they provide access across the trench for wildlife and livestock. Construction Techniques Page 3-7 S.• IdataIENVPROTiE&S P1ansIE&S Plan.doc a. Do not use topsoil for installing temporary soft trench plugs. b. Coordinate with the landowner to identify optimal locations for the placement of temporary hard trench plugs designed to provide access for livestock. c. Temporary trench plugs may be used in conjunction with interceptor dikes to prevent water in the trench from overflowing into sensitive resource areas (Figure 14). Attempt to divert trench overflow to a well-vegetated off-ROW location. 3.5.6 Trencb Dewateriag Trench dewatering may be periodically required along portions of the proposed pipeline prior to and/or subsequent to installation of the pipeline to remove collected water from the trench. Trench dewatering will be conducted in such a manner that no heavily silt-laden water flows into any waterbody or wetland. 2. The intakes of the hoses used to withdraw the water from the trench will be elevated and screened to minimize pumping of deposited sediments. 3. Water may be discharged into areas where adequate vegetation is present adjacent to the construction ROW to function as a filter medium. 4. Where vegetation is absent or in the vicinity of waterbodyl wetland areas, water will be pumped into a filter bag (Figure 15) or through a structure composed of sediment barriers. When using filter bags, secure the discharge hose to the bag with a clamp. 3.5.7 Pipe IBstallatioB 3.5.7.1 Stringing and Bending Following trench excavation, pipe sections will be delivered to the construction site by truck or tracked vehicle, and strung out along the trench. Individual pipe sections will be placed on temporary supports or wooden skids and staggered to allow room for work on the exposed ends. Certain pipe sections will be bent, as necessary, to conform to changes in slope and direction of the trench. 3.5.7.2 Welding and Weld Inspection Once the bending operation is complete, the pipe sections will be welded together on supports using approved welding procedures that comply with Company welding specifications. After welding, the welds will be inspected radiographically or ultrasonically to ensure their structural integrity. 3.5.7.3 Lowering in Lowering-in consists of placing the completed pipeline sections into the trench where a tie-in weld will be made. Lowering-in is usually accomplished with two or more sideboom tractors acting in Construction Techniques Page 3-8 S.- WwaJENYPROTtE&S PlansE&S Plan.doc unison and spaced so as not to buckle or otherwise damage the pipe. The pipeline will be lifted from the supports, swung out over the trench, and lowered directly into the trench. The equipment uses a "leap frogging" technique requiring sufficient area to safely move around other tractors within the construction ROW to gain an advanced position on the pipe. 3.5.8 Backrilling Backfilling consists of covering the pipe with the earth removed from the trench or with other fill material hauled to the site when the existing trench spoil is not adequate for backfill. Backfilling will follow lowering-in of the pipeline as close as is practical. In areas where the trench bottom is irregularly shaped due to consolidated rock or where the excavated spoil materials are unacceptable for backfilling around the pipe, padding material may be required to prevent damage to the pipe. This padding material will generally consist of sand or screened spoil materials from trench excavation. 1. Under no circumstances shall topsoil be used as padding material. 2. Excess rock, including blast rock, may be used to backfill the trench to the top of the existing bedrock profile in accordance with Company specifications. Any excess material will be spread within the ROW in upland areas and land contours will be roughed-in to match adjacent topography. 4. The trench may be backfilled with a crown over the pipe to compensate for compaction and settling. Openings will be left in the completed trench crown to restore pre-construction drainage patterns. Crowning shall not be used in wetland areas. 3.5.8.1 Permanent 71,-encb Plurs Permanent trench plugs are intended to slow subsurface water flow and erosion along the trench and around the pipe in sloping terrain (Figures 16, 17). Permanent trench plugs will be constructed with sand bags or an equivalent as identified in the permit requirements. On severe slopes greater than 30 percent, "Sakrete" may be used at the discretion of the Chief Inspector. a. Topsoil shall not be used to construct trench plugs. b. Permanent trench plugs, which are used in conjunction with interceptor dikes, shall be installed at the locations shown on the construction drawings or as determined by the EI. If not shown, use the following spacing: Slope (%) Spacing (feet) <5 No Structure 5-15 300 > 15 - 30 200 Construction Techniques Page 3-9 S ldatalENVPR071E&SPlanslE&SPlan.doc > 30 100 c. Trench plugs shall be installed at the base of slopes adjacent to waterbodies and wetlands, and where needed to avoid draining of a resource. 3.5.9 Hydrostatic Testing Once the pipeline is completed and before it is placed into service, it will be hydrostatically tested for structural integrity. Hydrostatic testing involves filling the pipeline with clean water and maintaining a test pressure in excess of normal operating pressures for a specified period of time (typically 8 hours). The testing procedure involves filling the pipeline with test water, performing the pressure test, and discharging the test water. 1. The EI shall notify appropriate state agencies (as identified in the Hydrostatic Test Package) of the intent to use specific test water sources at least 48 hours before testing activities (unless waived in writing). 2. Pumps used for hydrostatic testing within 100 feet of any waterbody or wetland shall be operated and refueled in accordance with the SPCC Plan. 3. Do not use state-designated exceptional value waters, waterbodies that 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. Use only the water sources identified in the Clearance Package/Permit Book. 4. Screen the intake hose to prevent entrainment of fish and other aquatic life. Maintain ambient, downstream flow rates to protect aquatic life, provide for all waterbody uses, and provide for downstream withdrawals of water by existing users. 6. Locate hydrostatic test manifolds outside wetlands and riparian areas to the greatest extent practical. 7. For an overland discharge of test water from a new pipeline, dewater into an energy dissipation device constructed of straw bales (Figures 18, 19). - 8. For an overland discharge of test water from an existing pipeline, dewater into an energy dissipation device constructed of straw bales and absorbent booms (Figure 18). If required by the appropriate permitting agency, the test water may be discharged through an appropriate filtration system including frac tanks and/ or carbon filters. 9. Dewater only at the locations shown on the construction drawings or locations identified in the Hydrostatic Test Package. 10. Locate all dewatering structures in a well-vegetated and stabilized area, if practical, and attempt to maintain at least a 50-foot vegetated buffer from adjacent waterbody/wetland areas. If an Construction Techniques Page 3-10 S. idatalE&WROM&S P1ans1E&SPlan.doc adequate buffer is not available, sediment barriers or similar erosion control measure must be installed. 11. Regulate discharge rate, use energy dissipation device(s), and install sediment barriers, as necessary, to prevent erosion, streambed scour to aquatic resources, suspension of sediments, flooding or excessive stream flow. 12. 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. 13. The EI shall sample and test the source water and discharge water in accordance with the permit requirements. 3.6 ROW Restoration and Final Cleanup Restoration of the ROW will begin after pipeline construction activities have been completed. Restoration measures include the re-establishment of final grades and drainage patterns as well as the installation of permanent erosion and sedimentation control devices to minimize post-construction erosion. Residential areas will be restored in accordance with Section 4.3.3. Property shall be restored as close to its original condition as practical unless otherwise specified by the landowner. 1. The Contractor shall make every reasonable effort to complete final cleanup of an area (including final grading and installation of permanent erosion control structures) within 10 days after backfilling the trench in that area If this schedule cannot be met, final cleanup must be completed as soon as practical. 2. The disturbed ROW will be seeded within 6 working days of final grading, weather and soil conditions permitting. 3. If final cleanup and seeding cannot be completed and is delayed until the next recommended growing season, the winter stabilization measures in Section 3.6.4 shall be followed. 4. Grade the ROW to pre-construction contours. 5. Spread segregated topsoil back across the graded ROW to its original profile. 6. Remove excess rock from at least the top 12 inches of soil to the extent practical in all rotated and permanent cropland, hayfields, pastures, residential areas, and other areas at the landowner's request. The size, density, and distribution of rock on the construction ROW should be similar to adjacent areas not disturbed by construction. Construction Techniques Page 3-11 S.•IdataIENVPROM&S PlansT&S Plan.doc 7. Make diligent efforts to remove stones greater than 4 inches if the off-ROW areas do not contain stones greater than 4 inches. The landowner may approve other rock size provisions in writing. 8. Leave travel lane open temporarily to allow access by construction traffic and install the temporary erosion control structures as specified in Section 3.5.2. When access is no longer required, the travel lane must be removed and the area restored. 9. Remove all construction debris (used filter bags, skids, trash, etc.) from the ROW and grade or till the ROW to leave the soil in the proper condition for planting. 3.6.1 Permanent Erosion Control 3.6.1.1 Permanent Interceptor Dikes Permanent interceptor- dikes are intended to reduce runoff _velocity and divert water off the construction ROW (Figure 12). Permanent interceptor dikes will be constructed of compacted soil. Sand bags may be used when directed by the EI. a. Install permanent interceptor dikes in all areas, except cultivated areas and lawns, at the locations shown on the construction drawings or as directed by the EI. If not shown, use the spacing outlined for temporary interceptor dike installation in Section 3.5.4. b. Install permanent interceptor dikes across the entire ROW at all waterbody and wetland crossings, and at the base of slopes adjacent to roads. When the ROW parallels an existing utility ROW, permanent interceptor dikes may be installed to match existing interceptor dikes on the adjacent undisturbed pipeline ROW. c. Construct interceptor dikes with a 2 to 8 percent outslope to divert surface flow to a stable vegetative area. In the absence of a stable vegetative area, install an energy-dissipating device at the end of the interceptor dike (Figure 12). d. Install chevron-style interceptor dikes on slopes when directed by the El (Figure 20). e. Install a rock lined drainage swale along the ROW with restricted drainage features when directed by the El. The drainage swale is generally 8 feet wide and a maximum of 18-24 inches deep (Figure 21). f. On slopes greater than 30 percent, install interceptor dikes with erosion control fabric on the swale side. 3.6.1.2 Erosion Control Fabric a. Install erosion control fabric at interceptor dike outlets and drainage swales as necessary or as directed by the EI (Figure 12, 21). Construction Techniques Page 3-12 S. WatalENVPROTIE&SPlanslE&SPlan.doc b. Install erosion control fabric or matting on slopes greater than 30 percent adjacent to roads or waterbodies (Figure 22). Anchor the erosion control fabric or matting with staples or other appropriate devices in accordance with the manufacturers' recommendations. c. The EI will direct the installation of high-velocity erosion control fabric on the swale side of permanent interceptor dikes (Figure 23). 3.6.2 Revegetation and Seeding Successful revegetation of soils disturbed by project-related activities is essential. Seeding will be conducted using the following requirements: 1. Fertilize and add soil pH modifiers in accordance with the recommendations in Appendix B. Incorporate recommended soil pH modifier and fertilizer into the top 2 inches of soil as soon as practical after application; 2. Seed slopes steeper than 30 percent immediately after final grading, weather permitting; Seed all disturbed soils within 6 working days of final grading, weather and soil conditions permitting; 4. Prepare seedbed in disturbed areas to a depth of 3 to 4 inches to provide a firm seedbed. When hydroseeding, scarify the seedbed to facilitate lodging and germination of seed; 5. Seed disturbed areas in accordance with the seed mixes, rates, and dates in Appendix B, except in upland areas where landowners may request alternative seed mixes. Seeding and mulching in cultivated cropland shall conform with the adjacent off ROW area unless otherwise requested by the landowner in writing; - 6. Perform seeding of permanent vegetation within the recommended seeding dates as outlined in Appendix B. If seeding cannot be done within those dates, use appropriate temporaryerosion control measures discussed in Section 3.5.2 and perform seeding of permanent vegetation at the beginning of the next recommended seeding season. Mulch in accordance with Section 3.6.3. Lawns may be seeded on a schedule established with the landowner; 7. Base seeding rates on Pure Live Seed (PLS). Use seed within 12 months of seed testing; 8. Treat legume seed with an moculant specific to the species (for conventional seeding methods, use 4 times the manufacturer's recommendation - for hydroseeding, use 10 times the manufacturer's recommendations); and 9. Uniformly apply and cover seed in accordance with Appendix B. In the absence of any recommendations, a seed drill equipped with a cultipacker is preferred for application, but broadcast or hydroseeding can be used at double the recommended seeding rates. Where seed is broadcast, firm the seedbed with a cultipacker or roller after seeding. Construction Techniques Page 3-13 S. WwalENYPROAMS PlansT,&S Plan.doc 3.6.3 Mulcb Mulch is intended to stabilize the soil surface and shall consist of straw, erosion control fabric, or some functional equivalent as approved by the El and Chief Inspector. Hay shall not be used for mulch. 1. Mulch before seeding if: a. Final cleanup, including final grading and installation of permanent erosion control measures, is not completed in an area within 10 days after the trench in that area is backfilled; or b. Construction or restoration activity is interrupted for extended periods, such as when seeding cannot be completed due to seeding period restrictions. NOTE: When mulching before seeding, increase mulch application on all slopes within 100 feet of waterbodies and wetlands to a rate of 3 tons/acre. 2. Mulch all disturbed ROW on slopes greater than 8 percent and in areas of dry sandy soil. Spread mulch uniformly over the ROW at a rate of 2 tons/acre of mulch. 3. Mulch with woodchips only under the following conditions with prior approval from the Chief Inspector or the El: a. Do not use more than 1 ton/acre; and b. Add the equivalent of 11 lbs/acre available nitrogen (at least 50 % of which is slow release). 4. Ensure that mulch is anchored to minimize loss by wind and water. Anchoring may be achieved by wet soil conditions (when approved by the EI), mechanical means, or with liquid mulch binders. 5. If a mulch blower is used, the strands of the mulching material shall be at least 8 inches long to allow anchoring. 6. When anchoring by mechanical means, use a mulch anchoring tool to properly crimp the mulch to a depth of 2 to 3 inches. 7. When anchoring with liquid mulch binders, use rates recommended by the manufacturer. Do not use liquid mulch binders within 100 feet of wetlands and waterbodies. 8. Install and anchor erosion control fabric, such as jute thatching, or bonded fiber blankets, at a minimum, on waterbody banks at the time of final bank recontouring. 3.6.4 Winter Stabilization In the event that the final phases of construction occur too late in the year for cleanup activities to proceed, the following procedures will be implemented along the disturbed ROW at those locations until final restoration measures can be completed: Construction Techniques Page 3-14 S. tdatalENVPROTIE&SPlansIE&SPlan.doc 1. Install permanent interceptor dikes at specified intervals on all slopes, or as directed by the El; 2. Install temporary sediment barriers adjacent to stream and wetland crossings, as well as other critical areas; 3. Seed and mulch the ROW and seed segregated topsoil piles in accordance with Appendix B; and 4. Remove flumes from waterbody crossings to reestablish natural stream flow. 3.7 Unauthorized Vehicle Access to ROW The Company will offer to install and maintain measures to control unauthorized vehicle access to the ROW based on requests by the manager or owner of forested lands. These measures may include: • Signs; • Fences with locking gates; • Slash and timber barriers, pipe barriers, or a line of boulders across the ROW; or • Conifers or other appropriate shrubs with a mature height of 4 feet or less across the ROW. Construction Techniques Page 345 S.-WXaIENVPR071E&S P1ans1E&S Plan.doc 4. SPECIAL CONSTRUCTION METHODS The Company will utilize the following specialized construction procedures for agricultural areas, road crossings, and residential areas along the pipeline project. The project construction drawings, Line Lists, and Construction Contract will indicate the locations where specialized construction methods will be used. 4.1 Agricultural Areas 4.1.1 Drain Tiles 1. Mark drain the locations identified during construction. 2. Probe all drainage file systems within the area of disturbance to check for damage. 3. Repair damaged drain tiles to their original condition (Figure 24). Filter-covered drain tiles may not be used unless the local soil conservation authorities and the landowner agrees in writing prior to construction. 4. Ensure that the depth of cover over the new pipeline is sufficient to avoid interference with drain file systems (existing or proposed). For adjacent pipeline loops in agricultural areas, install the new pipeline with at least the same depth of cover as the existing pipeline(s). 4.1.2 Irrigation 1. Maintain water flow in crop irrigation systems, unless shutoff is coordinated with affected parties. 2. Repair any damage to the systems as soon as practical. 4.13 Soil Compaction Mitigation Test topsoil and subsoil for compaction at regular intervals in agricultural areas disturbed by construction activities. Conduct tests on the same soil type under similar moisture conditions in undisturbed areas to identify approximate preconstruction conditions. Use COE-style cone 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. 4.2 Road Crossings Unpaved private and public roads supporting minimal traffic volumes are usually crossed by boring or by means of an open cut, if this method is approved by the owner or appropriate road management Special Construction Methods Page 4-1 S. IdataIENVPR07IE&SPlansE&SPlan.doc agency. An open cut crossing involves closing the road to all traffic, excavating one-half of the road at a time, or constructing an adequate detour around the crossing area (Figure 25). The trench for an open cut crossing is excavated with a backhoe or similar equipment, all backfill is compacted, and the road resurfaced. All state, national, and interstate highways as well as all railroads must be crossed by boring (Figure 26), unless the crossing permit allows an open cut crossing. Access roads shall be used in accordance with Section 3.2. 4.3 Residential Areas 4.3.1 Construction Procedures Specialized construction procedures will be utilized in areas of heavy residential or commercial/ industrial congestion where residences or business establishments lie greater than 25 feet but less than 50 feet from the edge of the construction ROW. 1. Install safety fence at the edge of the construction ROW for a distance of 100 feet on either side of the residence or business establishment. 2. Attempt to maintain a minimum distance of 25 feet between any residence/business establishment and the edge of the construction work area for a distance of 100 feet on either side of the residence/business establishment. 3. Attempt to leave mature trees and landscaping intact within the construction work area unless the trees and landscaping interfere with the installation techniques or present unsafe working conditions. 4.3.2 Contraction Techniques In addition to the previously identified specialized procedures, smaller "spreads" of labor and equipment, operating independent of the mainline work force, will utilize either the stove pipe or drag section pipeline construction techniques in those areas of congestion where a minimum distance of 25 feet cannot be maintained between the residence(or business establishment) and the edge of the construction work area. In no case shall the temporary work area be located within 10 feet of a residence unless the landowner agrees in writing, or the area is within the existing maintained ROW. The following techniques shall be utilized for a distance of 100 feet on either side of the residence or business establishment at the locations identified in the Construction Contract and/or Line List. - 1. The stove pipe construction technique is a less efficient alternative to the mainline method of construction, typically used when the pipeline is to be installed in very close proximity to an existing structure or when an open trench would adversely impact a commercial/industrial establishment. The technique involves installing one joint of pipe at a time whereby the welding, weld inspection, and coating activities are all performed in the open trench. At the end of each day after the pipe is lowered-in, the trench is backfilled and/or covered with steel plates or timber mats. The length of excavation performed each day cannot exceed the amount of pipe installed. Special Construction Methods Page 4-1 S.•%dataIENVPR071E&SP1ans1E&SPlan.doc 2. The drag section construction technique, while less efficient than the mainline method, is normally preferred over the stove pipe alternative. This technique involves the trenching, installation, and backfill of a prefabricated length of pipe containing several segments all in one day. At the end of each day after the pipe is lowered-in, the trench is backfilled and/or covered with steel plates or timber mats. Use of the drag section technique will typically require adequate staging areas outside of the residential and/or commercial/industrial congestion for assembly of the prefabricated sections. 4.3.3 Cleanup and Restoration Reseed all disturbed lawns with a seed mixture acceptable to landowner or comparable to the adjoining lawn. 2. Landowners shall be compensated for damages to ornamental shrubs and other landscape plantings based on the appraised, value as set forth in the Guide-for Plant Appraisal, authored by the Council of Tree and Landscape Appraisers (CTLA), 8'h Edition and published in 1992 by the International Society of Arboriculture. 3. Landowners shall be compensated for damages in a fair and reasonable manner, and as specified in the damage provision within the controlling easement on each property. Special Construction Methods Page 4-3 S:WatalEIVYPROnE&SPlanslE&SPlan.doc 5. WATERBODY CROSSINGS The following section describes the construction procedures and mitigation measures that will be used for pipeline installations at waterbodies. The intent of these procedures is to minimize the extent and duration of project related disturbances within waterbodies. 5.1 Waterbody Definitions The term "waterbody" as used in this Plan 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. In this Plan, waterbodies are characterized into three main categories depending on the width of the waterbody. The categories are as follows: • A "minor waterbody" includes all waterbodies less than or equal to 10 feet wide at the water's edge at the time of construction. • An "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. • A "major waterbody" includes all waterbodies greater than 100 feet wide at the water's edge at the time of construction. • A "state designated waterbody" includes all perennial waterbodies that support coldwater fisheries and warmwater fisheries considered significant by the state. • A "non-state designated waterbody" includes intermittent drainage ditches, intermittent streams, and perennial warmwater streams not considered significant by the state. The waterbody crossing procedures described in this Plan comply with the Section 404 Nationwide permit program terms and conditions (33 CFR Part 330). 5.2 General Waterbody Procedures Decisions regarding waterbody crossing techniques will be reviewed and based on agency consultations. Pipeline construction across waterbody channels may result in short term water quality impacts. Mobilization of construction equipment, trench excavation, and backfilling will be performed in a manner that will minimize the potential for erosion and sedimentation within the waterbody channel. Erosion control measures will be implemented to confine water quality impacts within the immediate construction area and to minimize impacts to downstream areas. The length of the crossing, the sensitivity of the area, existing conditions at the time of the crossing, and permit requirements will determine the most appropriate measures to be used. Waterbody Dossing Page 5-1 S.WXa%ENVPROTIE&SPlanstE&SPlan.doc 5Z.1 Time Window for Construction 1. Unless expressly permitted or further restricted by the appropriate state agency in writing on a site- specific basis, crossings shall be constructed during the following time windows: a. Coldwater Fisheries - June 1 through September 30; and b. Coolwater and Warmwater Fisheries - June 1 through November 30. 5.2.2 Temporary Equipment Bridges A temporary equipment bridge is a structure that may be installed across a waterbody to provide a means for construction equipment to cross the stream while minimizing impacts to the channel bottom or banks. 1. Until the equipment bridge is installed, only clearing equipment may cross the waterbody and the number of crossings shall be limited to one crossing per piece of equipment, unless otherwise authorized by the appropriate permitting agency. 2. Construct equipment bridges using one of the following methods: a. Equipment pads and culverts (Figure 27); b. Clean crushed stone and culverts (Figure 28); or c. Flexi-float or portable bridges (Figure 29). 3. Construct crossings as close to perpendicular to the axis of the waterbody channel. 4. Design and maintain each equipment bridge to withstand the highest flows that would occur. 5. Do not use soil to construct or stabilize equipment bridges. 6. Maintain equipment bridges to prevent soil from entering the waterbody. 7. Remove equipment bridges as soon as practical after permanent seeding unless agency permits authorized that the bridge remains in place. 8. If there will be more than 1 month between final cleanup and the beginning of permanent seeding and reasonable alternative access to the ROW is available, remove equipment bridges as soon as practical after final cleanup. 5.2.3 Clearing and Grading 1. Confine construction activities and ground disturbance to within the ROW boundaries shown on the construction drawings. Waterbody Crossing Page 5-2 S. WalatENVPROTIE&S PkmIE&S Plan.doc 2. Restrict extra work areas (such as staging areas and additional spoil storage areas) to those shown only on the construction drawings. All extra work areas must be located at least 50 feet away from waterbody boundaries, where site-specific conditions permit. If site-specific conditions do not permit a 50-foot setback, the Company can receive written approval from the FERC to locate these extra work areas at least 10 feet from the water's edge. If the pipeline parallels a waterbody, attempt to maintain at least 15 feet of undisturbed vegetation between the waterbody and the ROW except at the crossing location. 4. Clear the ROW adjacent to all waterbodies up to the high water bank (where discernible). Immediately remove all cut trees and branches that inadvertently fall into a waterbody and stockpile in an upland area on ROW for disposal. 6. Grade the ROW adjacent to waterbodies up to within 10 feet of the high water bank, leaving an ungrubbed vegetative strip intact. 7. Clearing and grading operations may proceed through the 10-foot vegetative strip only on the working side of the ROW in order to install the equipment bridge and travel lane. Use temporary sediment barriers to prevent the flow of bank spoil into the waterbody. 8. Maintain adequate flow rates to protect aquatic life and prevent the interruption of existing downstream uses. 5.2.4 Installing TemporaryErosion and Sediment Control 1. Install sediment barriers 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 replacement by permanent erosion controls or restoration of adjacent upland areas is complete. 2. Install sediment barriers across the entire construction ROW at all waterbody crossings. Temporary interceptor dikes or driveable berms as described in Section 3.5.4 may be used in lieu of sediment barriers in front of equipment bridges or timber mats across the travel lane. 3. install sediment barriers as necessary along the edge of the construction ROW to contain spoil and sediment within the ROW where waterbodies are adjacent or parallel to the constriction ROW. 4. Use trench plugs at all non-flumed waterbody crossings to prevent diversion of water into upland portions of the pipeline trench and to keep any accumulated trench water out of the waterbody. Trench plugs shall be of sufficient size to withstand upslope water pressure. Waterbody Crossing Pages-3 _ S.-WwaIENVPROnE&SPlanslE&SPlan.doe 5.2.5 various 7j?pes of Crossings Construction at waterbodies will be conducted using two principal crossing methods, a "dry" crossing and a "wet" crossing. The "dry" crossing procedure is further divided into a flumed crossing and a dam and pump crossing. These methods are designed to maintain downstream flow at all times and to isolate the construction zone from the stream flow 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. The "wet" crossing procedure involves open cutting the waterbody without isolating the construction zone from the stream flow. 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. All streams, their classifications, timing windows, and crossing procedures will be identified in the Clearance Package/Permit Book and on the construction drawings. Table 6-1 outlines the general procedures to be followed at all waterbody crossings. 5.2.5.1 General Crossing Procedures 1. Dewater trench in accordance with the procedures described in Section 3.5.6. 2. For minor waterbodies: a. Place all spoil from the waterbody within the construction ROW at least 10 feet from the water's edge or in the extra work areas shown on the construction drawings. Use sediment barriers to prevent flow of spoil into the waterbody. 3. For intermediate waterbodies: a. Less than 30 feet in width, place all spoil from the waterbody within the construction ROW at least 10 feet from the water's edge or in the extra work areas shown on the construction drawings. Use sediment barriers to prevent flow of spoil into the waterbody. b. Greater than 30 feet in width, spoil may be temporarily sidecast into the waterbody provided that site specific approval is received from the appropriate permitting agency. 4. For major waterbodies: a. Place all upland bank spoil from the waterbody within the construction ROW at least 10 feet from the water's edge or in the extra work areas shown on the construction drawings. Use sediment barriers to prevent flow of spoil into the waterbody. b. Sidecasting is permitted in major waterbodies upon approval from the appropriate permitting agencies. 5. Restore and stabilize the banks and channel in accordance with Section 5.2.6. Waterbody Crossing Page 5-4 S: WwalENVPR07IE&S PlanslE&S Plan.doc 5.2.5.2 Flumed Crossing The flumed crossing method utilizes a flume pipe(s) to transport stream flow across the disturbed area and allows trenching to be done in drier conditions (Figure 30). The flume pipe(s) installed across the trench will be sized to accommodate anticipated stream flows. This method is utilized for perennial, minor waterbodies that are state designated fisheries including coldwater fisheries and warmwater fisheries considered significant by the state. Flumes are generally not recommended for use on a watercourse with a broad unconfined channel, unstable banks, a permeable substrate, excessive stream flow, or where the installation and construction of the flume crossing will adversely affect the bed or banks of the stream. 1. Cross all minor waterbodies that are state-designated fisheries, as identified in the Clearance Package/ Permit Book, using a dry crossing technique (Figures 30, 31): 2. All construction equipment must cross state-designated fisheries on an equipment bridge as specified in Section 5.2.2. 4. The flumed crossing shall be installed as follows: a. Install flume pipe(s) after blasting (if required), but before trenching; b. Properly align flume pipe(s); c. Use sand bags or equivalent dam diversion structure to provide a seal at either end of the flume to channel water flow; d. Do not remove flume pipe during trenching, pipe laying, or backfilling activities unless authorized by agency permits; e. Thread pipe underneath the flume pipe(s); and f. Remove all flume pipes and dams that are not also part of the equipment bridge after final cleanup but before permanent seeding. 5.2.5.3 Dam and Pump Crossing The dam and pump method is presented as an alternative dry crossing procedure to the flumed crossing. The dam and pump crossing is accomplished by utilizing pumps to transport stream flow across the disturbed area (Figure 31). This method involves placing sandbags across the existing stream channel upstream from the proposed crossing to stop water flow and downstream from the crossing to isolate the work area. Pumps are used to pump the water across the disturbed area and back into the stream further downstream. This method is intended for use at perennial, minor waterbodies and state designated fisheries including coldwater fisheries and warmwater fisheries considered significant by the state. The dam and pump procedure allows for more space and flexibility during the pipe installation, which shortens the duration of time spent at the waterbody. 1. The dam and pump method may be used for crossings of minor waterbodies where fluming is not required. Waterbody Crossing Page 5-5 S. IdatalENYPROTIE&S PlanslE&S Plan.doc 2. The company will develop a specific dam and pump plan for written approval from the FERC and the appropriate permitting agency for the following instances: a. Minor waterbodies that are state-designated fisheries (as identified in the Clearance Package/Pen-nit Book; and b. Waterbodies that are greater than 10 feet. 3. The dam and pump plan will describe all measures used to maintain downstream flows including: a. Number and capacity of active and backup pumps; b. Types of dams to be used upstream and downstream of the crossing; c. How streambed scour would be prevented at the pump discharge; and d. How the operation would be monitored if the crossing takes longer than one normal construction day. 4. The dam and pump crossing shall be installed as follows: a. Install and properly seal sandbags at the upstream and downstream location of the crossing; b. Create an in-stream sump using sandbags if a natural sump is unavailable for the intake hose; c. Initiate pumping of the stream around the work area prior to excavating the trench; d. Screen all intake hoses to prevent the entrainment of fish and other aquatic life; e. Direct all discharges from the pumps through energy dissipaters to minimize scour and siltation; f. Monitor pumps at all times until construction of the crossing is completed; and g. Following construction, remove the equipment crossing and sandbag dams. 5.2.5.4 Wet CrnssrnQ This construction technique is typically used to cross waterbodies that are non state-designated as well as intermediate and major waterbodies with substantial flows that cannot be effectively culverted or pumped around the construction zone using the dry crossing techniques (Figure 32). Non-state designated waterbodies include perennial warmwater streams not considered significant by the state, intermittent drainage ditches, and intermittent streams- The wet-ditch crossing shall be installed as follows: 1. For minor waterbodies: a. Equipment bridges are not required at non state-designated fisheries. 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; Waterbody Crossing Page 5-6 S: IdataIENVPROYIE&S P1ans1E&.S Plan.doc c. Complete trenching and backfilling in the waterbody (not including blasting) 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 as specified in Section 5.2.2; and b. Attempt to complete trenching and backfill work within the waterbody (not including blasting) 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. 5.2.6 Restoration 1. Return all waterbody banks to preconstruction contours. 2. Use clean gravel or native cobbles for the upper 12 inches of trench backfill in all waterbodies identified in the Clearance Package/Permit Book as coldwater fisheries. 3. Stabilize waterbody banks and install temporary sediment barriers within 24 hours of completing the crossing. For dry crossings, complete bank stabilization before returning flow to the waterbody channel. 4. Limit the placement of riprap to the slopes along the disturbed waterbody crossing. 5. Install erosion control fabric along waterbodies with low flow conditions (Figure 33). 6. Revegetate disturbed riparian areas with conservation grasses and legumes in accordance with the recommended Upland Seed Mix in Appendix B. In the event that final cleanup is deferred more than 10 days after the trench is backfilled, all slopes within 100 feet of waterbodies shall be mulched with 3 tons/acre of straw. 7. Remove all temporary sediment barriers when restoration of adjacent upland areas is successful as specified in Section 8.1. Waierbody Crossing Page S-7 S. IdataIENVPR071E&S PlanslE&S Plan.doc 8. Install a permanent interceptor dike and a trench plug at the base of slopes near each waterbody crossed. Locate the trench plug immediately upslope of the interceptor dike. Permanent interceptor dikes may not be installed in agricultural areas.

Waterbody Crossing Page 5-8 S: tdatatENVPROM&SPlanslE&SPlan.doc 6. WETLAND CROSSINGS 6.1 Definition The term "Wetland" as used in this Plan includes any area that satisfies the requirements of the current Federal methodology for identifying and delineating wetlands. Wetland areas have been delineated prior to construction and are identified on the construction drawings. The wetland crossing procedures described in this Plan comply with the Section 404 Nationwide permit program terms and conditions (33 CFR Part 330). 6.2 General Procedures 6.2.1 Clearing and Grading 1. Confine construction activity and ground disturbance in wetland areas to a construction ROW of 75 feet or as shown on the construction drawings. 2. Restrict extra work areas (such as staging areas and additional spoil storage areas) to those shown only on the construction drawings. All extra work areas must be located at least 50 feet away from wetland boundaries, where site-specific conditions permit. If site-specific conditions do not permit a 50-foot setback, the Company can receive written approval from the FERC to locate these extra work areas at least 10 feet from the wetland. 3. Aboveground facilities shall not be located in any wetland, except as permitted or where the location of such facilities outside of wetlands would prohibit compliance with DOT regulations. 4. If standing water or saturated soils are present, either use low-ground-weight construction equipment or install timber riprap or prefabricated equipment mats on the working side of the ROW during clearing operations. Do not use more than two layers of timber riprap to stabilize the ROW. 5. Cut vegetation off at or grind stumps to ground level, leaving existing root systems in place. Immediately remove all cut trees and branches from the wetland and stockpile in an upland area on ROW for disposal. 6. 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 ROW in wetlands unless the Chief Inspector and El determine that safety-related construction constraints require removal of tree stumps from under the working side of the ROW. 7. Do not cut trees outside of the construction ROW to obtain timber for riprap or equipment mats. 8. Cleared materials (slash, logs, brush, wood chips) shall not be permanently placed within wetland areas. Wetland Crossings Page 6-1 s: tdatatENVPRonE&s PlanstE&S Plan.doc 6.Z2 Temporary Erosion and Sediment Control 1. Install sediment barriers immediately after initial ground disturbance at the following locations: a. Within the ROW at the edge of the boundary between wetland and upland; b. Across the entire ROW immediately upslope of the wetland boundary to prevent sediment flow into the wetland; c. Along the edge of the ROW to protect adjacent, off ROW wetland; and d. Along the edge of the ROW as necessary to contain spoil and sediment within the ROW. 2. Maintain all sediment barriers throughout construction and reinstall as necessary (such as after backfrlling of the trench) until replaced by permanent erosion controls or restoration of adjacent upland areas is complete in accordance with Section 8.1. 6.2.3 Crossing Procedure 1. Minimize the duration of construction-related disturbance within wetlands. 2. Do not use rock, soil imported from outside the wetland, tree stumps, or brush riprap to stabilize the ROW. 3. Perform topsoil segregation in accordance with Section 3.5.3.1 and trench dewatering in accordance with Section 3.5.6. 4. Where water and other site conditions allow, the pipeline may be assembled in an upland area and the "push-pull" or "float" techniques used to place the pipe in the trench. 5. Install trench plugs and/or seal the trench bottom as necessary to maintain the original wetland hydrology at locations where the pipeline trench may drain a wetland. 6. Install a permanent interceptor dike and a trench plug at the base of slopes near the boundary between the wetland and adjacent upland areas. Permanent interceptor dikes shall not be installed in agricultural areas. 7. Restore segregated topsoil to its original position after backfilling is complete. When required, additional fill material imported from off the ROW must be approved by the El. The original wetland contours and flow regimes will be restored to the extent practical. 6.2.4 Cleanup and Restoration 1. Revegetate the ROW with annual ryegrass at 40 lbs/acre PLS or with the recommended Wetland Seed Mix in Appendix B, unless standing water is present. 2. Do not use lime or fertilizer in wetland areas. Wetland Crossings Page 6-2 S: idatalENVPROTIE&S Plans%E&S Plan.doc 3. Mulch the disturbed ROW only when required by the appropriate land management or state agency, as identified in the Clearance Package/Pennit Book. 4. In the event that final cleanup is deferred more than 10 days after the trench is backfilled, all slopes adjacent to wetlands shall be mulched with 3 tons/acre of straw for a minimum of 100 feet on each side of the crossing. 5. Remove all timber riprap and prefabricated equipment mats upon completion of construction. 6. Develop specific procedures in coordination with the appropriate land management or state agency, where necessary, to prevent the invasion or spread of undesirable exotic vegetation (such as purple loose strife and phragmites). 7. Ensure that all disturbed areas permanently revegetate in accordance with Section 8.1. 8. Remove temporary sediment barriers located at the boundary between wetland and adjacent upland areas after upland revegetation and stabilization of adjacent upland areas are successful as specified in Section 8.1. Welland Crossings Page 6-3 S.-WataTNVPR0nE&S PlansE&S Plan.doc 7. SPILL PREVENTION CONTROL 7.1 The Contractor shall adhere to the SPCC Plan in Appendix C at all times. 1. Do not store hazardous materials, chemicals, fuels, or lubricating oils within 100 feet of any wetland, waterbody or within any designated municipal watershed area where feasible. If the 100- foot setback cannot be met, this activity will be performed in accordance with Section 3.1 of the SPCC Plan. 2. Refuel all construction equipment at least 100 feet from any wetland or waterbody, where feasible. If the 100-foot setback cannot be met, this activity will be performed in accordance with Section 3.1.3 of the SPCC Plan. 3. Do not perform fondu or concrete coating activities within 100 feet of any wetland or waterbody. If the 100-foot setback cannot be met, these activities will be- conducted in accordance with Section 3.1.4 of the SPCC Plan. Spill Prevention and Control Page 7-1 S. IdatalENVPR07IE&SPlanslE&SPlan.doc 8. POST CONSTRUCTION ACTIVITIES 8.1 Post-Construction Monitoring All projects conducted under this Plan, with the exception of insitu pipe replacements (i.e. DOT- mandated replacements, line lowerings, and anomaly repairs), shall meet the monitoring requirements set forth in this section. Company personnel shall perform the following: 1. Establish and implement a program to monitor the success of restoration upon completion of construction and restoration activities; 2. Conduct follow-up inspections of all disturbed upland areas after the first growing season and if necessary, the second growing season (normally 3 to 9 months and 15 to 21 months after seeding, respectively) to determine the success of revegetation; 3. Revegetation shall be considered successful if the vegetative cover is sufficient to prevent the erosion of soils on the disturbed ROW. Sufficient coverage in upland areas is defined when vegetation has a uniform 70 percent vegetative coverage. If sufficient vegetative cover has not been achieved or if there are excessive noxious weeds after two full growing seasons, a professional agronomist shall be consulted to determine the need for additional restoration measures (such as fertilizing or reseeding). The measures recommended by the agronomist will be implemented by the Company, 4. Restoration shall be considered successful if the ROW surface condition is similar to adjacent undisturbed lands, revegetation is successful, and all temporary erosion control devices are removed; 5. Monitor and correct problems with drainage and irrigation systems resulting from pipeline construction in active agricultural areas; 6. Monitor crops for at least 2 years to determine the need for additional restoration; 7. Make efforts to control unauthorized off-road vehicle use, in cooperation with the landowner, throughout the life of the project. Maintain signs, gates, and vehicle trails as necessary; 8. Monitor wetlands annually for the first 3 to 5 years (or as required by permit) to determine the success of revegetation. Wetland revegetation will be considered successful when the native herbaceous and/or woody cover is at least 80 percent of the total cover and native species diversity is at least 50 percent of the diversity originally found in the wetland. If revegetation is not successful at the end of 3 years, the Company shall develop and implement (in consultation with a professional wetland ecologist) a plan to actively revegetate the wetland with native wetland herbaceous and woody plant species; and Post Construction dcdW ies Page 8-1 S.• IdataIENVPR071E&SPlans1E&SPlan.doc 9. Inspect all temporary remaining erosion and sedimentation controls during routine patrols to ensure proper functioning. Any deficiencies found will be reported and corrected as needed. Once the area has revegetated and stabilized, the erosion controls will be removed. 8.2 Post-Construction Maintenance All projects conducted under this Plan, with the exception of insitu pipe replacements (i.e. DOT- mandated replacements, line lowerings, and anomaly repairs), shall meet the maintenance requirements set forth in this section. The following requirements restrict the amount of vegetation maintenance that can occur on new pipeline facilities. Where the newly established pipeline ROW is located on other existing ROWS not affiliated with the Company, the easement holder or owner will continue to maintain their ROWS using procedures specified in their vegetative management programs. 8.2.1 Uplands Routine maintenance of the ROW is required to allow continued access for routine pipeline patrols, maintaining access in the event of emergency repairs, and visibility during aerial patrols. In upland areas, maintenance of the ROW will involve clearing the entire ROW of woody vegetation. 1. Routine vegetation maintenance clearing shall be conducted no more frequently than onceevery 3 years. However, to facilitate periodic corrosion and leak surveys, a 10-foot wide corridor centered on the pipeline may be maintained annually in a herbaceous state. 2. In no case shall routine vegetation maintenance clearing occur between April 15 and August 1 of any year. 8.2.2 Waterbodies and Wetlands 1. Vegetation maintenance practices on the construction ROW adjacent to waterbodies will consist of maintaining a riparian strip that measures 25 feet back from the mean high water mark. This riparian area will be allowed to permanently revegetate with native plant species across the entire ROW. 2. Vegetation maintenance practices over the full width of the construction ROW in wetlands is prohibited. 3. To facilitate periodic corrosion and leak surveys at wetlands and waterbodies, a 10-foot wide corridor centered on the pipeline may be maintained in a herbaceous state. Trees and shrubs greater than 15 feet in height that are located within 15 feet of the pipeline may be cut and removed from the ROW. 4. Herbicides or pesticides shall not be used in or within 100 feet of a wetland or waterbody, except as specified by the appropriate land management or state agency. Post Construction Activities Page 8-2 S:IdataiENYPRonE&sPlansT,&SPlan.doc 8.3 Reporting The Company shall maintain records that identify by milepost: 1. Method of application, application rate, and type of fertilizer, pH modifying agent, seed, and mulch used; 2. Acreage treated; 3. Dates of backfilling and seeding; and 4. Names of landowners requesting special seeding treatment and a description of the follow-up actions. For the FERC-certificated projects, the Company will file quarterly activity reports documenting problems, including those identified by the landowner, and convective actions taken for at least 2 years following construction.

X All tanks and storage areas shall be inspected daily for leaks and deterioration. X Vehicle mounted tanks shall be equipped with flame/spark arrestors on all vents to ensure that self ignition does not occur. X Tanks will not be used to store incompatible materials in sequence unless first thoroughly decontaminated. 2 X Any tank utilized at different construction locations will be thoroughly decontaminated between locations. 3.13 Loading/Unloading Areas X Transferring of liquids and refueling shall only occur in predesignated locations at least 100 feet from all waterbodies and wetlands and 200 feet from any water well. X All loading/unloading areas will be closely monitored to prevent leaks and spills, and ensure immediate response in the event of a spill. X All hose connections shall be inspected for leaks. If leaks should occur, the operation shall cease until the leak is repaired or a containment pan is placed under the leaking connection. X Any service vehicle used to transport lubricants and fuel must be equipped with an emergency response kit. At a minimum, this kit must include: - 10, 48" x 3" oil socks, - 5, 17" x 17" oil pillows, - 1, 10" x 4" oil boom, - 20, 24" x 24" x 3/8" oil mats, - Garden size, 6 mil, polyethylene bags, - 10 pair of latex gloves, and - 1, 55-gallon polyethylene open-head drum. X In addition, a smaller chemical response kit shall be available which contains: - 1 bag of loose chemical pulp, - 2 to 3, 17" x 17" chemical pillows, - 2,48" x 3" chemical socks, - 5, 18" x 18" x 3/8" adsorbent mats, - garden size, 6 mil, polyethylene bags, - 10 pair of latex gloves, -1, 30-gallon polyethylene open head drum, and - hazardous waste labels. X Each refueling vehicle shall have a sufficient number of shovels, brooms, 10 mil polyethylene sheeting, and fire protection equipment to contain a moderate oil/fuel spill. X The area beneath loading/unloading location shall be inspected for spills before and after each use. 3.1.4 Concrete Coating Areas for Field Joints X Concrete coating of field joints for road, rail, waterbody, and wetland crossings shall be performed at least 100 feet from the edge of all waterbodies. X Where topographic conditions and/or work space limitations necessitate application of concrete coating within 100 feet of a waterbody, the following containment measures shall be performed: 3 a. Concrete coating materials shall be temporarily stored in an earthen berm with polyethylene underling of sufficient mil thickness, or in a portable containment tray constructed of steel plate measuring a minimum of four (4) feet square by one (1) foot deep. b. Portable-mechanical mixing equipment, if required, shall be operated within a containment area constructed of temporary earthen berms and polyethylene underling of sufficient mil thickness. C. Manual mixing of concrete materials in a portable container (such as a 55 gallon drum cut in half, or equivalent) shall be performed within an earthen berm with polyethylene underling of sufficient mil thickness, or within a portable containment tray constructed of steel plate, measuring a minimum of four (4) feet square by one (1) foot deep. 3.2 EMPLOYEE TRAINING All personnel involved in the construction of the proposed facilities will be aware of the SPCC/PPC Plan. Training briefings will be conducted by the Contractor Superintendent and the Company Chief Inspector on the job site. 3.3 EMERGENCY EQUIPMENT The construction site will have adequate manpower and equipment necessary to divert any spill from reaching water bodies and wetland areas.

X Arrange for the transport of hazardous waste and waste containing PCBs greater than 1 ppm to an approved disposal facility within the applicable federal and state regulatory requirements. 4.2 SPILL CLEAN-UP PROCEDURES The following identifies the clean-up and control measures to be utilized by the contractor in the event of a spill of oil, fuel or a hazardous substance on the construction right-of-way. 4.2.1 Oil/Fuel Spills X Small spills and leaks must be remediated as soon as feasible. Use adsorbent pads wherever possible to reduce the amount of contaminated articles. X Restrict the spill by stopping or diverting flow to the oil/fuel tank. X If the release exceeds the containment system capacity, immediately construct additional containment using sandbags or fill material. Every effort must be made to prevent the seepage of oil into soils and waterways. X If a release occurs into a facility drain or nearby stream, immediately pump any floating layer into drums. For high velocity streams, place oil booms or hay bales between the release area and the site boundary. As soon as possible, excavate contaminated soils and sediments. X After all recoverable oil has been collected and drummed, place contaminated soils and articles in containers. 6 X For larger quantities of soils, construct temporary waste piles using plastic liners placing the contaminated soils on top of the plastic and covered by plastic. Plastic-lined roll-off bins should be leased for storing this material as soon as feasible. X Label the drum following the procedures outlined in the Company's Environmental Procedures Manual. X Move drum to secure staging or storage area. X Document and report activities to the ECD as soon as feasible. 4.2.2 Hazardous Substance Releases X Identify the material and quantity released. X Block off drains and containment areas to limit the extent of the spill. Never wash down a spill with water. X Ensure that Personal Protective Equipment and containers are compatible with the substance. X Collect and reclaim as much of the spill as possible using a hand pump or similar device. Containerize contaminated soils in appropriate DOT container in accordance with the Company's Environmental Procedures Manual. Never place incompatible materials in the same drum. X Sample the substance for analysis and waste profiling, according to instructions from the ECD. X Decontaminate all equipment in a contained area. Collect and containerize decontamination fluids. X Label the drum following the procedures outlined in the Company's Environmental Procedures Manual. X Move the drum to secure staging or storage area. X Document and report activities to the ECD as soon as feasible. 43 DISPOSAL OF CONTAMINATED MATERIALS/SOILS X The Contractor shall work with the ECD to characterize waste generated during this project. All wastes generated as a result of spill response activities will be analyzed to determine if hazardous, or if PCBs are greater than 1 ppm. Knowledge of the contaminant(s) may be applied to classify the wastelspill materials as determined by the ECD. X The Contractor is responsible for the proper disposal of wastes generated during this project that is determined by the ECD to be non-hazardous and to contain PCBs less than 1 ppm. This includes obtaining applicable authorizations and registrations for waste disposal. 7 X The ECD is responsible for the proper disposal of hazardous wastes and PCB wastes containing PCBs greater than 1 ppm generated during this project, including obtaining applicable EPA Identification Numbers. X Hazardous wastes and waste containing PCBs shall be stored in a secured location (i.e. fenced, locked, etc.) until such time as this material is transported off-site. At no time will hazardous waste be stored for a period exceeding 90 days nor a waste with PCBs greater than 50 ppm be stored for a period exceeding 30 days. 4.4 EQUIPMENT CLEANING/STORAGE X Upon completion of remedial activities, the Contractor shall be responsible for decontaminating emergency response equipment. X The Contractor shall be responsible for replacing all spent emergency response equipment prior to resuming construction activities. X Reusable personal protective equipment shall be tested and inventoried by the Contractor prior to being placed back into service. 5.0 HOUSEKEEPING PROGRAM The construction area will be maintained in a neat and orderly manner. Solid wastes, such as food wrappings, cigarette butts and packets, styrofoam cups and plates, and similar wastes will be disposed of off-site, not in the construction hole. Any spills or leaks will be cleaned up as expeditiously as possible. Trash will be routinely collected for off=site disposal. Container storage areas will be maintained in a neat and orderly manner. 6.0 SECURITY Hazardous wastes and waste containing PCBs greater than 50 ppm will be stored in a secured location (i.e. fenced, locked, etc.). Temporary fencing will be installed around fuel storage areas to prevent tampering by unauthorized personnel during non-operational hours. 7.0 EXTERNAL FACTORS There will be no direct effect on the construction site due to a power outage or snowstorm. In the event of a flood or strike, all tanks and containers would be removed from the right-0f--way and placed in a secure area. 8 TABLE I MATERIAL AND WASTE INVENTORY Oil/Fuel: Quantity (Gallons) Storage Location Reportable Quantity Commercial Chemicals: Quantity (Gallons) Storage Location Reportable Quantity Hazardous and Non-Hazardous Wastes: Quantity (Gallons) Storage Location Reportable Quantity THIS TABLE TO $E COMPLETED BY CONTRACTOR 10 TABLE II EMERGENCY RESPONSE AND PERSONAL PROTECTIVE EQUIPMENT Spill Response: Equipment Quantity Location Fire Protection: Equipment Quantity Location Personnel Protection: Equipment Quantity Location OMP.EfiD?

INTRODUCTION This Plan describes the construction measures to be taken in the event that significant problems arise during the directional drill process. The goal of this contingency plan is to: 1. Prevent the release of drilling mud into a waterbody or wetland being crossed; and 2. Provide a secondary procedure in case a pilot hole cannot be drilled. II. HANDLING AND CONTAINMENT OF DRILLING MUD To reduce the quantity of drilling mud to be prepared, the mud will be recycled and filtered to eliminate the rock and soil particles cut from the borehole path then recirculated. An enclosure will be built to contain the drilling mud. The drilling operation shall be monitored at all times, at both the entry and exit points, to ensure that the mud is being contained in the pit. Additional measures shall be taken if necessary, including hand placed barrier (i.e., straw/hay bales, sand bags, silt fences, etc.) and/or earthen dikes. Sediment barriers may also be installed at the edge of the right-of-way, and between the drill pit and the waterbody being crossed, if required. With any directionally drilled pipeline installation there exists some potential for lost circulation. In the event that there is an inadvertent loss of drilling mud during circulation, one or more of the following measures can be taken: 1. Keep fluid pressure at a minimum in the borehole annulus to reduce pressure on the formation. 2. Keep the borehole clean of drilled cuttings as much as possible to reduce borehole pressure from bridging. 3. Move the drill pipe up and down the borehole in a smooth manner to reduce pressure surges. 4. Keep the amount of drilling fluid to a minimum to reduce friction drag and pressure. 5. Use the surface mud cleaning system to its maximum to remove drilled solids from the system, thereby reducing the mud weight, which in turn reduces pressure while pumping. Surface spills due to pipe or drill rig leaks will immediately be contained with hand placed barriers or local dikes and then pumped into the main mud enclosure for treatment and recirculation. Drilling mud pushed out during the pullback will be contained with hand placed barriers or adike and pumped into the mud enclosure for re-use or disposal. II. SECONDARY CONTAINMENT In the event that a pilot hole cannot be drilled, the following measures shall be taken: 1. Check the equipment to verify its integrity and to determine where the problem is occurring. 2. If the obstruction is on the land portion of the drill, excavate and remove the obstruction, if possible. 3. If the obstruction cannot be excavated or removed, direct the drill bit around the obstruction if technically feasible. When the drill bit is directed around an obstruction, it can possibly be backed up a short distance and redirected around the obstruction using basically the same pilot hole. 4. In the event that the hole must be abandoned and the pilot hole drilled from a different location, fill the abandoned hole with drilling mud. Drilling mud in the pit shall be pumped into a frac tank for reuse or disposal and the pit backfilled. 5. In the event that the pull string cannot be pulled through, salvage as much pipe as possible and attempt the directional drill from a new location. The abandoned hole shall be filled with drilling mud. IV. DISPOSAL OF DRILLING MUD Non-contaminated drilling mud will be disposed of in one of the following ways: 1. Spreading over farm fields to improve agricultural soil under specific conditions; or 2. Transportation to an authorized disposal site.

The Project consists of two components: The Mainline Expansion and the Extension. The facilities located within the State of North Carolina are only associated with the Extension. The Extension involves new pipeline facilities in North Carolina and includes construction of: ¦ 7.69 miles of new mainline Extension; ¦ 0.39 miles of a new pipeline lateral extending from the mainline (Henry County Power Lateral); ¦ associated mainline valves and appurtenant pipeline facilities. East Tennessee will construct the Patriot Project over a period of 18 months beginning in July 2002 and ending by January 1, 2004. 1 Section 2 Wetland Delineation Report Approach In accordance with the FERC's Guidance Manual for Environmental Report Preparation, ETNG has prepared this Wetland Delineation Report for the Patriot Project. This report contains the following information: ¦ Methods used for wetland delineations; ¦ Milepost locations, wetland identifiers, wetland classifications, and length of wetlands identified along the pipeline route; ¦ Data summary forms summarizing hydrology, soils, and vegetation of each wetland; and ¦ Names and qualifications of persons conducting the delineations. This report summarizes all wetlands that will be affected by pipeline construction, including those along the construction right-of-way and associated temporary work areas, staging areas, above ground valves, piping and appurtenant pipeline facilities, and access roads; only those wetlands on properties where access was denied for field surveys are not reported. An addendum to this report summarizing those wetlands will be provided when permission is obtained. Section 3.0 provides information related to the wetland delineation methodology used for this survey. References are provided in Section 4.0. Appendix A provides a summary table of all wetlands affected by the proposed Project. Appendix B provides copies of all Army Corps of Engineers (ACOE) Wetland Delineation Data Forms for each wetland. Appendix C provides a key for the list of acronyms used to catalog plant species on the Army Corps Data Forms. Qualifications of all wetland delineation personnel are provided in Appendix D. 2 Section 3 Wetland Delineation Methodology 3.1 Purpose The general purpose of the wetland delineation effort was to obtain detailed and accurate information on wetlands crossed by the Project, as required by the FERC, the United States Army Corps of Engineers, and applicable state agencies. The specific objective of the wetland delineation effort was to identify all wetland boundaries that will be affected by the pipeline construction ROW and associated temporary work areas, staging areas, above ground valves, piping and, appurtenant pipeline facilities, and access roads. 3.2 Field Methods During late winter/early spring of 2001, wetlands crossed by the proposed Project were delineated by wetland scientists of Duke Engineering & Services. Formal wetland delineations were performed using methods described in the 1987 Corps of Engineers Wetland Delineation Manual (Technical Report Y-87-1). The `Routine On-Site Wetland Determination Method' was selected as the most appropriate technique. All wetlands were classified in the field to the "class" level using the U.S. Fish and Wildlife Service's (USFWS) classification system (Cowardin et al. 1979). The civil or `centerline' survey was completed, i.e., flagged and staked in the field, prior to wetland delineation surveys. Table 1 lists the flagging color conventions that were used during civil and wetland surveys. 3 Section 3 Wetland Delineation Methodology TABLE 1 FLAGGING CONVENTIONS Flagging Color Color Indicates Red Flagging Existing centerline of the "hot' line or existing facilities Orange Flagging Centerline of the proposed pipeline White Flagging Survey limits Pink "Wetland Delineation" Flagging Wetland boundaries The following typical corridor width was surveyed: ¦ Virgin ROW - The total survey corridor was 200 feet wide. The proposed centerline was staked, and the survey area was 100 feet on either side of the centerline (See Figure 1). FIGURE 1 TYPICAL EXTENSION SURVEY CORRIDOR 100'¦-100'> ¦ ¦ ¦ ¦ ¦ .a ¦ a ¦ ¦ a ¦ p' ¦ ¦ ¦ ¦ ¦ I ¦ C/ 1L Wetland flagging was day-glo pink in color pre-printed with the words "WETLAND DELINEATION' in black letters was used to delineate the boundary of a wetland within the survey corridor. Every wetland flag was legibly marked with a series of three identification codes that identified the delineating team and year, the number of the wetland, and the flag number (Global 4 Section 3 Wetland Delineation Methodology Positioning System [GPS] point indicator). The markings were made using a permanent waterproof marker. Flags were spaced so they represented a clear indication of the wetland boundary (i.e., more flags on curved or non-linear boundaries, and less flags on linear boundaries). Figure 2 depicts a typical wetland system that may be encountered in the field. The wetland is one contiguous system that enters the survey corridor at different points along the ROW. The first wetland is Wetland C1-10. This means that wetland delineation team "C" surveyed this wetland in 2001, and it was the tenth wetland they surveyed that year. The endpoint of Wetland C1-10 is when the wetland exits the survey corridor. Wetland C1-11 begins as this wetland enters the survey corridor again. The same occurs in the transition between Wetland C1-11 and Wetland C1-12. . FIGURE 2 WETLAND DELINEATION EXAMPLE 1 Nk Wetland C1-1 END FLAG _hk I, STARTFLAG Ii/ END FLAG Wetland C1-11-?

The first flag read "C1-10- 1 START" written with waterproof marker. The team continued to hang flags along the wetland boundary with the next flag reading "C1-10-2". In the lower right corner of the diagram, the team wrote on the flag "C1-10-4 END" if indeed that was the fourth wetland point flagged. The flagging continued for the other boundary of Wetland C1-10 beginning with "C1-10-5 START". For circular or other wetlands (Figure 3) that fall entirely in the ROW, marking requirements began with a START flag (e.g., "A1-22-1 START"). Flagging continued sequentially until the area was defined. If the wetland contained 13 points, the last flag read "A1-22-13 END CONNECT TO 1".

Four wetland subclasses are currently identified as being crossed by these facilities and are as follows: 6 Section 3 Wetland Delineation Methodology ¦ Palustrine emergent marsh; ¦ Palustrine wet meadow; ¦ Palustrine, broad-leaved deciduous scrub-shrub; and ¦ Palustrine broad-leaved deciduous forested. Following is a brief description that includes a general overview of vegetation, hydrology, and soils of each particular wetland type, along with a general discussion of wetland functions and values that are characteristic of that wetland type. 3.3.1 Palustrine Emergent System (PEM) This class of wetlands near the Project study area is characterized and dominated by herbaceous hydrophytes such as wool grass (Scirpus cyperinus), fowl manna-grass (Glyceria striata), reed canary grass (Phalaris arundinacea), numerous sedge species (Carex spp.), soft rush (Juncus effusus), and smartweed species (Polygonum spp.) (Fleming et. al. 2001; Chester et al. 1993). Representative types of emergent wetlands crossed by the Project include emergent marsh and wet meadow. Emergent Marsh Emergent marsh wetlands occurred on mineral soils or fine-grained organic soils (muck or peat) that have a hydrologic regime of permanently flooded to permanently saturated. Water levels may fluctuate seasonally, but soil substrate is rarely dry, and there is usually standing water in the fall and spring. Representative functions and values for these wetlands included groundwater discharge, nutrient removal/transformation, sediment/toxicant retention, and wildlife habitat. Plant species that are representative of this wetland type found during this study included soft rush, broad-leaved cattail (Typha latifolia), shallow sedge (Carex lurida), fowl bluegrass (Poa palustris), creeping jennie (Lysimachia nummularia), and reed canary grass. 7 Section 3 Wetland Delineation Methodolo The dense foliage and seasonal water of emergent wetlands provide breeding habitat for invertebrates as well as amphibians and reptiles such as the northern spring peeper (Pseudacris crucifer crucifer), green frog (Rana clamitans melanota), bullfrog (Rana catebeiana), eastern painted turtle (Chrysema picta picta), and the eastern snapping turtle (Chelydra serpentina serpentina) (Mitchell and Reay 2000; VADGF 2000). Root stalks and stems of cattail are the preferred food item of muskrats (Ondatra zibethica), and seeds of wetland grasses, sedges, and rushes are consumed by a variety of songbirds and waterfowl species. The typically dense growth of vegetation provides shelter and nesting habitat for a variety of avian species such as mallard (Anas platyrhynchos), American bittern (Botaurus lentiginosus), and red-winged blackbirds (Agelaius phoeniceus) (Martin et al. 1961). Wet Meadow Wet meadow wetlands were typically graminoid-dominated herbaceous fields found on mineral soils. These wetlands have seasonally saturated to seasonally flooded hydrologic regimes that have saturated soils near the surface, but without standing water for most of the year. Representative functions and values for these areas included nutrient removal/transformation, sediment/toxicant retention, and wildlife habitat. Wet meadows included agricultural fields and open fields associated with existing ROW. They were primarily dominated by soft rush, meadow fescue (Festuca pratensis), creeping jennie, shallow sedge, and other various graminoids. Wet meadows support herbaceous cover that provides nesting for a variety of open-land songbirds such as song sparrow (Melospiza melodia), Eastern meadowlark (Sturnella magna), red-winged blackbird, and common yellowthroat (Geothlypis trichas). Wet meadow habitat is also favorable for several species of small mammals, including the shorttail shrew (Blarina brevicauda), meadow vole (Microtus pennsylvanicus), and eastern harvest mouse (Reithrodontomys humulis). Several species of bats including the big brown bat (Eptesicus fuscus) and the hoary bat (Lasiurus cinereus cinereus) are often observed foraging above these areas, especially if near wooded areas. Wet meadows are also preferred nesting and foraging habitat for northern harrier (Circus cyaneus) and provide foraging habitat for other species of raptors. 8 Section 3 Wetland Delineation Methodolo 3.3.2 Palustrine Scrub-Shrub System (PSS) Palustrine scrub-shrub wetlands are dominated by woody vegetation that is less than 6 m tall. The dominant species of shrubs in these wetlands near the Project study area include arrowwood (Viburnum dentatum), black willow (Salix nigra), tag alder (Alnus serrulata), cane (Arundinaria gigantea), Chinese privet (Ligustrum sinense), swamp rose (Rosa palustris), and red maple (Fleming et. al. 2001; Radford et. al. 1968). The herbaceous layer typically includes species such as sensitive fern (Onoclea sensibilis), fowl manna-grass, soft rush, fringed sedge (Carex crinita), bladder sedge (Carex intumescens), smartweeds, spotted jewelweed (Impatiens 'capensis), and false nettle (Boehmeria cylindrica) (Fleming et. al. 2001; Radford et. al. 1968). Community equilibrium in this wetland type varies from relatively stable `climax' shrub communities under wetter conditions to regenerating forested wetlands recently disturbed by activities such as logging. Soils in these types of wetlands ranged from mineral to organic, and corresponding hydrology typically ranges from seasonally saturated to semi-permanently saturated and seasonally flooded. Scrub-shrub wetlands provide nesting, foraging, and breeding habitat for a variety of wildlife species. Dense thickets of berry-producing shrubs will often provide food and cover for numerous songbirds including common yellowthroats, yellow warblers (Dendroica petechia), gray catbirds (Dumetella carolinensis), song sparrows, and willow flycatchers (Empidonax traillii). In addition, the flooded areas within these wetlands can provide important breeding pools for amphibians such as spring peepers and gray tree frogs. The abundance of insects and frogs in these areas attracts predatory species like great blue herons (Ardea herodius), raccoons (Procyon lotor), and mink (Mustela vison). Depending on the amount of open water associated with these wetland areas, other common wildlife species likely to occur in scrub-shrub wetlands include white-tailed deer (Odocoileus virginianus), muskrat, beaver (Castor canadensis), and various species of waterfowl. Broad-leaved Deciduous Broad-leaved deciduous scrub-shrub wetlands along the Project occurred along the shores of waterbodies, in wet depressions, and in transition zones between emergent wetlands and upland 9 Section 3 Wetland Delineation Methodolo communities. Soils were usually mineral or muck, and hydrology ranged from seasonally and semi- permanently saturated, to seasonally flooded. Representative functions and values for these wetlands included floodflow alteration, sediment stabilization, nutrient removal/transformation, sediment/toxicant retention, and wildlife habitat. The dominant species of shrubs in these wetlands along the project included northern spicebush (Lindera benzoin), black willow, swamp rose, common greenbrier (Smilax rotundifolia), and brookside alder (Alnus serrulata). These wetlands often supported small or stunted individuals of tree species such as red maple, willow oak (Quercus phellos), and sweet gum (Liquidambar styraciflua).- Depending on the density of shrub cover, the herbaceous layer ranged from sparse to dense and common species included cinnamon fern (Osmunda cinnamonea), royal fern (Osmunda regalis), fringed sedge, and other graminoids. 3.3.3 Palustrine Forested System (PFO) Palustrine forested wetlands are characterized by woody vegetation that is at least 6m tall and provides at least 50 percent canopy closure. Species composition of overstory trees near the Project study area range from monotypic to mixed stands of red maple, tuliptree (Liriodendron tulipifera), cherrybark oak (Quercus pagoda), American elm (Ulmus americana), hackberry (Celtis laevigata), green ash (Fraxinus pennsylvanica), and loblolly pine (Pinus taeda). The understory trees typically consist of ironwood (Carpinus caroliniana), red maple, and American holly (Ilex opaca). The shrub layer can be well developed and may be quite dense. Characteristic shrub species include viburnums (Viburnum spp.), blueberries (Vaccinium spp.), and alder (Alnus spp.). Commonly occurring vines include poison ivy (Toxicodendron radicans), crossvine (Bignonia capreolata), Japanese honeysuckle (Lonicera japonica), and greenbrier species (Smilax spp.). Herbs typically include clearweed (Boehmeria cylindrica), Christmas fern, sedge species (Carex spp.), smartweeds, and violet species (Viola spp.) (Radford et. al. 1968). Hydric mineral soils were typical in these wetlands, although greater organic accumulations occurred in some wetlands. Generally, these wetlands are without standing water for most of the year. Forested wetlands with open water provide 10 Section 3 Wetland Delineation Methodolmy valuable breeding habitat for waterfowl and amphibians. Snags that attract cavity nesting waterfowl, woodpeckers, and nesting owls are a common feature in forested wetlands. Broad-leaved Deciduous Broad-leaved deciduous forested wetlands are mixed hardwood swamps that occur in poorly drained depressions and floodplains, usually on mineral soils. Representative functions and values for these wetlands include nutrient removal/transformation, sediment/toxicant retention, production export, floodflow alteration, and wildlife habitat. Species composition in the overstory of forested wetlands surveyed along the Project supported a mixture of deciduous trees including red maple, green ash, sweetgum, willow oak, and American sycamore (Platanus occidentalis). The shrub layer was usually well developed and in some cases quite dense, however, in some forested wetlands the shrub layer was absent. Characteristic shrub species included American sycamore, northern spicebush, Virginia rose (Rosa virginiana), common greenbrier, and brookside alder. The herbaceous layer of forested wetlands was often dominated by ferns and sedges including, cinnamon fern, royal fern, fringed sedge, and thicket sedge (Carex abscondita). Broad-leaved deciduous forested wetlands provide habitat for raccoon, beaver, big brown bat, white- tailed deer, mallard, wood duck (Aix sponsa), great blue heron, belted kingfisher (Megaceryle alcyon), barred owl (Strix varia), Carolina chickadee (Parus carolinensis), northern parula warbler (Parula americana), prothonotary warbler (Protonotaria citrea), northern water snake (Nerodia sipedon sipedon), spotted salamander (Ambystoma maculatum), gray treefrog (Hyla versicolor), southeastern chorus frog (Pseudacris feriarum), wood frog (Rana sylvatica), and the southern green frog (Rana clamitans melanota). The seasonally flooded bottomlands and the adjacent rivers recruit relatively large concentrations of Canada geese (Branta canadensis) and other waterfowl species such as puddle ducks (Areas spp.). These bottomlands also support a high density of wetland dependent bird species including the wood duck, prothonotary warbler, common yellowthroat, Swainson's warbler (Limnothlypteris swainsonii), and Louisiana waterthrush (Seiurus motacilla). 11 Section 3 Wetland Delineation Methodology 3.4 Wetland Status 3.4.1 Extension The primary impact to wetlands other than temporary soil disturbance will be some permanent cover type conversion from forested wetland to scrub-shrub and emergent wetland types. There will be no wetland impacts associated with construction of the aboveground facilities. This is due to the fact that wetlands are generally sparse in the project area and were avoided during the planning process. During surveys along the proposed Extension, 10 wetlands were identified as being affected by pipeline construction. Of these, 5 (50%) were palustrine emergent and 5 (50%) were palustrine forested (Appendix A). Approximately, 1,792 linear feet of wetland will be temporarily affected by construction and approximately 1.79 acres of wetland will be permanently converted from forested wetland to scrub-shrub or emergent wetland types. It is anticipated that there will be no permanent alterations to wetland hydrology. 3.4.2 Henry County Power Lateral During surveys along the proposed Henry County Power Lateral, one wetland was identified as being affected by pipeline construction. This wetland was a complex of palustrine emergent, palustrine scrub-shrub, and palustrine forested (Appendix A). Approximately, 780 linear feet of wetland will be temporarily affected by construction and approximately 0.90 acres of forested wetland will be permanently converted from forested wetland to scrub-shrub or emergent wetland types. It is anticipated that will be no permanent alterations to wetland hydrology. There will be no wetland impacts associated with construction of the aboveground facilities. 12 Section 4 References Chester, E.W., B.E. Wofford, R. Kral, H. DeSelm, and A.M. Evans. 1993.

I have managed a small company, written my own reports, carried out my own field work, and done most of my graphics during this period. I have led several field teams of biologists and have managed projects of from $2000. to $200,000. in value. I have been involved in environmental impact studies and environmental assessments on which I have teamed with landscape architects, engineers, economists, and other professionals. I have produced numerous published vegetation maps during the last 15 years. I have occasionally been hired as a technical writer/editor and have extensive experience writing and editing biological reports. During these years, I have published a book on the spiders of South Carolina, have a forthcoming book in press with the University of South Carolina, written numerous papers in several fields, described several species of plants, and participated in several conservation projects. Finally, I have participated on the committees of three masters level graduate students at Clemson University and recently served on a Ph.D. student's committee. I have participated in research expeditions to China, southeastern Asia, and Australia and am currently working on two historical botany papers concerning western China. In 1998, I started a small nonprofit company, terra incognita, which carries out environmental consulting work in the United States.

Construction is planned in Tennessee, Virginia, and North Carolina. This project, named the Patriot Project, will initially transport 200 million cubic-feet-per-day of natural gas beginning in the winter of 2004. The project is designed to serve growing natural gas demand in the southeast, enhance the regional supply basin, and bring natural gas supply to areas that currently have none. The purpose of this report is as follows: ¦ Summarize existing information on state and federally listed endangered and threatened (E&T) species potentially affected by the proposed Patriot Project; ¦ Provide information on agency consultation, species accounts and habitat descriptions; and ¦ Propose E&T survey locations and schedules to be conducted prior to construction. This report only focuses on E&T species and does not address species that are considered rare or of special concern, i.e., those that do not have legal designation. ETNG does not plan to conduct specific surveys for rare species, however, if these species are encountered during surveys for other species, they will be included in our survey report. 1.1 Background Specifically, the Patriot Project will involve two major components: the Mainline Expansion and the Extension (Table 1, Figure 1). USGS Quads depicting the proposed routes are found in Appendix A. The Mainline Expansion is associated with approximately 110 miles of pipeline construction along ETNG's existing right-of way (ROW) in Tennessee and Virginia; testing of approximately 77 miles of pipeline along ETNG's ROW in Tennessee; the installation of five 1 C-' W E"'I w z z O E 0 ri a? rOr,, v z a w a a w W H V °a a ?O?-?

The Mainline Expansion is expected to be phased into service between the spring of 2003 and spring of 2004. The Extension entails construction of approximately 92.61 miles of new pipeline in Virginia and North Carolina, as well as three new meter stations. Construction of the Extension and parts of the Mainline Expansion are slated for 2002. A seven-mile lateral is proposed for Pittsylvania and Henry counties, Virginia, and Rockingham County, North Carolina. Construction of the lateral is slated for a spring of 2004 in-service date. ETNG proposes to use a nominal construction ROW of 100 feet for installation of the pipeline associated with the Patriot Project. The construction ROW will be expanded beyond 100 feet where additional workspace is required to facilitate construction in areas such as major road or waterbody crossings. Topsoil segregation and side slope construction will mostly be accommodated within the 100-foot-wide construction ROW. Most vegetative impacts associated with the testing of the existing pipeline will be within the existing ROW, although some additional workspace beyond the ROW may be required. All forested areas not used for the permanent ROW will be allowed to revegetate to pre-construction conditions via natural succession. On the Mainline Expansion, parallel sections of pipe (often referred to as relays or loops) will be installed within the existing ROW and no new permanent ROW will be required except at specific locations. Vegetative impacts associated with the testing of the pipe (often referred to as uprates) will also be within the existing ROW and restricted primarily to the beginning and terminus of the test section. Furthermore on the uprate sections, vegetative impacts will also occur where the pipeline requires replacement at road and waterbody crossings, per Department of Transportation regulation. These areas are depicted on the USGS Quads provided in Appendix A. On the Extension, 50 feet of the construction ROW will be maintained as permanent ROW for operation of the pipeline. This will result in the permanent conversion of forested habitat to an early- successional habitat due to periodic maintenance, mowing, and tree removal of a 50-foot-wide ROW in upland areas, and a 30-foot-wide ROW in wetland areas. 6 ETNG has identified additional temporary workspace (ATWS), staging areas, access roads, and pipeyards that are required during construction. The locations of the access roads are depicted on the USGS Quads in Appendix A and tabulated in Table 2.

The entirety of the `footprints' of the staging areas, ATWS, and pipeyards will be searched if they fall within a designated E&T survey area. Potential affects to E&T species on access roads will be minimal and only on the edge of the road and there will be no instream work on the access roads. Thus, ETNG proposes to only survey for plants on the edges of these roads and for nesting Loggerhead shrike, i.e.,10 feet on either side of the edge of the road, if the roads are within a designated E&T survey area. All construction and restoration will be done in accordance with ETNG's Erosion and Sediment Control Plan (E&SC Plan) which incorporates the FERC's Upland Erosion Control, Revegetation, and Maintenance Plan, Wetland and Waterbody Construction and Mitigation Procedures, and the respective states' erosion and sediment control Best Management Practices (BMPs). 7 1.2 Goals and Objectives The goals of the E&T species study are to identify and document known or anticipated state and federally listed E&T plant and wildlife species and their critical habitats within the immediate vicinity of the pipeline corridor. This study will be accomplished through a three-phase approach: ¦ Landscape Analysis - Based on pre-survey planning such as aerial photo interpretation, initial agency and expert consultation, and field reconnaissance along the entire line, habitats along the route were classified as either: (1) unlikely to harbor E&T species and their habitat (e.g., croplands and lawns); (2) highly likely or known to support E&T species (e.g., areas identified by the VA Natural Heritage Program) and will likely require survey; (3) or areas of indeterminate status where surveys may be required. ¦ Agency Consultation - Based on consultation with the various state and federal natural resource agencies in Tennessee, Virginia, and North Carolina, the list of species to be surveyed, survey locations and periods, survey methodology, agreed upon survey experts, ,and other pertinent recommendations will be fine tuned. ¦ On-site Surveys - Field surveys in areas classified as (2) and (3) may be conducted to document the occurrence and characteristics of the E&T species. These surveys will be conducted during the appropriate periods (e.g., flowering period), along designated areas (see Appendix A), and will be conducted by an agreed upon expert. 8 Section 2 Agency Consultation ETNG consulted with the various state and federal natural resource agencies listed in Table 3 to determine if state or federally listed E&T species occur within the Patriot Project area. Copies of these letters can be found in Appendix B.

A summary of all E&T species mentioned in the responses from the agencies is provided in Table 4. This table provides specific information regarding species status, county where the species may occur, the Patriot Project facility that may affect the species, pertinent agency comments, and the proposed survey schedule. Figure 2 illustrates the proposed survey schedule. Mr. Garland Pardue, Supervisor, USFWS - Raleigh Field Office - The USFWS recommended field surveys for federally listed threatened or endangered species possibly impacted by the Patriot Project. Also, a request for more detailed information was requested by the.USFWS. NCDENR Natural Heritage Program, Division of Parks and Recreation - It was stated by this department that the Smooth coneflower (Echinacea laevigata) may occur in the Patriot Project area. It was recommended that field surveys be conducted for this species. Ms. Danielle Pender, North Carolina Wildlife Resources Commission - The department recommended contacting the USFWS regarding endangered species issues associated with the Patriot Project. Also, it recommended perpendicular stream crossings utilizing the directional bore method to lessen the potential impacts to fish and wildlife species. The department expressed concern for the federal and state endangered James spinymussel (formerly the James River spiny mussel; Pleurobema collina) and the state endangered green floater (Lasmigona subviridis). 10 cd <d •p •D N N Co > o o N ?

This section also provides species accounts, legal status, and required habitats. These accounts are subdivided by state and county for ease of reference. Furthermore, this section provides specific information on proposed survey locations based on landscape analyses such aerial photo interpretation, initial agency and expert consultation, and field reconnaissance along the line. These areas are depicted on the USGS Quads provided in Appendix A. 3.1 E&T Species James Spinymussel (Pleurobema collina) - This mussel species is state and federally listed endangered. The North Carolina Wildlife Resources Commission (NCWRC) (letter dated February 21, 2001) stated this species occurs in the Dan River system in Rockingham County. Although the North Carolina Department of Environment and Natural Resources, Division of Parks and Recreation (NCDENR) has no record of this species within the project area, the NCWRC (NCWRC telephone memo dated July 10, 2001) has indicated that suitable habitat is present at the proposed crossings of Dry Creek and Martin Creek. Surveys will be conducted at these crossings by a DE&S/Foster Wheeler staff scientist using the proposed survey methodology presented in Section 3.4 below. Green Floater (Lasmigona subviridis) - The green floater is state listed endangered. It is a small species, adults are usually less than 55 mm in length, and inhabit small to medium-sized streams. It is intolerant of very strong currents and often is found in quiet pools and eddies with gravel and sand substrate. The NCWRC (2001) stated this species occurs in the Dan River system in Rockingham County. Although the NCDENR has no record of this species within the project area, the NCWRC (telephone memo dated July 10, 2001) has indicated that suitable habitat is present at the proposed crossings of Dry Creek and Martin Creek. Surveys will be conducted at these crossings 13 Section 3 Discussion by a DE&S/Foster Wheeler staff scientist using the proposed survey methodology presented in Section 3.4 below. Smooth Coneflower (Echinacea laevigata) - This rhizomatous perennial herb has light pink to purplish flower rays that are usually drooping. The flower heads are usually solitary. This state and federally listed endangered member of the aster family is only known to survive in Virginia, North Carolina, South Carolina, Georgia, Alabama, and Arkansas. The habitat for this species is open woods, cedar barrens, roadsides, clearcuts, limestone bluffs, and utility rights-of-way, usually in association with magnesium and calcium rich soils. In North Carolina, soils associated with gabbro and diabase can harbor this coneflower. Optimal sites are characterized by. abundant sunlight and little competition in the herbaceous layer. Flowering occurs from May through July (USFWS 1993). The USFWS (2001) and the NCDENR (2001a) reported that this species occurs in several specific locations within Rockingham County, North Carolina, along the Extension. Surveys were conducted during the week of July 16, 2001 in all suitable habitats in Rockingham County along the Extension from MP 54+7.60 to the terminus of the proposed project and along the Henry County Power Lateral from MP HC+0.00 to the Virginia border (Appendix A). In association with the surveys, directed searches during the flowering period were conducted within a 200-foot corridor. A DE&S botanical expert conducted the field surveys. In addition to looking for the target species, ETNG passively searched for the following species: the state significantly rare American barberry (Berberis canadensis), the state candidate Carolina birdfoot-trefoil (Lotus helleri), and the southeastern bold goldenrod (Solidago rigida var glabrata). 3.2 Proposed Mussel Survey Methodology Based on information provided by the NCWRC, suitable habitat exists for the James spinymussel and the green floater within the Dan River drainage system. Although the ETNG project does not the Dan River, several tributaries to the Dan River are crossed in Rockingham County. Thus, surveys for rare mussels are proposed for two streams within Rockingham County: Martin Creek 14 Section 3 Discussion (MP S4+7.70) and Dry Creek (MP 54+13.70), as requested by the NCWRC. Photos and data sheets of these streams are provided in Appendix C. The general procedure for the mussel surveys consists of two levels of intensity. The actual stream crossing ROW will be intensively searched for freshwater mussels. The ROW is the area of the stream bed which may be disturbed during the pipeline construction work and is typically 100 feet wide. The entire ROW will be searched, making a complete count of all listed species found. The second level of effort consists of a timed search upstream and downstream of the pipeline crossing. The creek area 100 meters upstream from the edge of the ROW and 400 meters downstream from the edge of the ROW will be searched for both creeks. The amount of search time may vary depending on stream size and other site-specific conditions but is expected to average about one to two person-hours per 100 meter reach. The survey area will also be dependent on available access and landowner permission. Mussel searches will be done through a combination of visual assessment in shoreline areas and snorkeling and/or wading with a viewscope in shallow water areas. Deep pool (> 3-6 feet) areas will not be surveyed with this methodology. The species of interest are generally headwater stream species found in riffle and shoal habitats and are not expected to occur in the deeper pooled areas. The survey will start at the downstream end of the survey area and work upstream to avoid clouding the water with sediments. All mussels found will be identified and replaced back in the substrate. A count by survey area (ROW, upstream or downstream) will be recorded for each listed species as well as a note of general abundance of other species (rare, common, and abundant). In addition to the mussel counts, a description of general habitat conditions will be recorded for each stream section. At a minimum these will include average stream width and water depth, stream habitat type (e.g., riffle, run, pool), substrate and flow conditions. Photographs will be taken of the survey area and a map locating any listed species found will be developed. Photographs will be taken of each listed species found and if requested, voucher specimens will be collected. The shoreline area of each stream will also be searched for evidence of mussel shells and all listed species will be recorded and placed in labeled bags. 15 Section 4 Conclusion If the respective state and federal agencies concur with the list of species in this report requiring surveys and methodology, ETNG will commence surveys or refine the study plans based on agency input. ETNG has already gained approval for the survey period and methodology (as described above) from the NCDENR, NCWRC, and the USFWS (Raleigh office) to conduct surveys for the smooth coneflower in North Carolina. Surveys were conducted the week of July 16, 2001. Survey information will remain confidential and will be provided to federal and state agencies in the form of a report for inclusion in their database. Specific mitigation plans for species that could be potentially affected during construction will be developed pending the outcome of the surveys along with a final survey report. 16 Section 5 References Cited North Carolina Department of Environment and Natural Resources, Division of Parks and Recreation (NCDENR).

Fletcher Duke Engineering and Services 500 Washington Avenue Portland, Maine 04103 Subject: Further Scoping for the East Tennessee Natural Gas Company natural gas pipeline system, Rockingham County, North Carolina. NCWRC No. P.01.06.26.01 Dear Mr. Fletcher: Biologists with the North Carolina Wildlife Resources Commission (NCWRC) have reviewed the subject document. Our comments are provided in accordance with provisions of the Fish and Wildlife Coordination Act (48 Stat. 401, as amended; 16 U.S.C. 661 et seq.), North Carolina Environmental Policy Act (G.S. 113A-1 through 113A-10; 1 NCAC 25), and North Carolina General Statutes (G.S. 113-131 et seq.). NCW'RC commented on the original scoping for this project (Fender, 21 February 2001). Since that time we have received two additional letters from Duke Engineering and Services requesting further comments regarding East Tennessee Natural Gas Company's (ETNG) alterations to the original plans. One was concerning a proposed expansion that included a 7.02-mile lateral and the other was for some slight revisions to the main pipeline route. We will address both letters here. The proposed lateral appears to parallel NC SR 1741 to the west, from the Virginia/North Carolina state line to a position approximately 2000 feet south of the state line. The actual centerline of the project is under development; therefore, ETNG is requesting comments along a 2,000-foot-wide corridor. Installation will require a 100-foot wide construction right-of-way and will retain 50 feet of permanent easement. Our records show that the Significant Natural Heritage Area (SNHA), Leaksville Loam Forests is located just to the east of NC SR 1741 and that the state significantly rare, Southeastern bold goldenrod (Solidago rigida ssp glabrata) is located within the proposed corridor.

The new route is similar to the original, with the only major difference being that the new route will not cross the Dan River. The actual centerline of the project is under development; therefore, ETNG is requesting comments along a one-mile wide corridor. In our original letter we expressed concern regarding impacts to the Dan River due to the great number of sensitive and rare species that are known to occur in that system. Although the proposed new route may not impact the Dan River directly, please be aware that many of the streams are tributaries to the Dan River. The new proposed route has potential to impact several streams in the Roanoke River Basin including Covenant Branch, Dry Creek, Martin Creek, Rock Creek, Smith River, and their tributaries. There are records for the state significantly rare, Roanoke hog sucker (Hypentelium roanokense) in Dry Creek. The SNHA areas and rare plant species that were mentioned in our original comments also have potential to be impacted by the revised route. Please refer to our earlier letter (Pender, 21 February 2001) for more information on natural resource concerns, and for general comments on pipeline location in relation to streams, secondary and cumulative impacts; and our general guidelines for preparing an environmental document. Thank you for the opportunity to provide input in the early planning stages for this project. If we can be of further assistance, please contact our office at (919) 528-9886. Sincerely, Danielle R.

Our comments are provided in accordance with provisions of the Fisb and Wildlife Coordination Act (48 Stat. 401, as amended; 16 U.S.C. 661 et sect.), North Carolina Environmental Policy Act (G.S.113A-i through 113A 10;1 NCAC 25), and North Carolina General Statutes (G.S.113-131 et seq). We appreciate your request for scoping comments; however, we recommend that in the future the State Clearing House be contacted directly so that all appropriate agencies may have comment opportunity. East Tennessee Natural Gas Company (ETNGr) proposes to expand its existing natural gas pipeline system to a new terminus near Eden, North Carolina. The project consists of Mainline Expansion in Tennessee and Virginia and Patriot Extension in Virginia and North Carolina. The proposed Patriot Extension entails construction of approximately 95 Wailes of new pipeline through Virginia, entering North Carolina at the border of Henry County, Virginia and Rockingham County, North Carolina near Martin Creek. Approximately 4.7 miles of pipeline will be located in North Carolina.

Additionally, the N.C. Division of Parks and Recreation, Natural Heritage Program has identified several Significant Natural Heritage Areas within the proposed location of the pipeline including Fitzgerald Woodland, Leaksville Loam Forests, Roundhouse Road Forest, and Widemouth Creek Conglomerate Exposure. We are concerned about affects to sensitive and tare species. 't'here are records for the existence of the federal and state endangered, James River spiny mussel (pleurobema collina), the federal species of concern and state endangered, green floater (Lasmigona subwridis), the state significantly rare. Roanoke hog sucker (Hypenteliwn roanokeme), and the state species of concern, bigeye jumprock (Scartomyzon ariomus) in the Dan rover system. Additionally, several listed plant species occur in the area including the federal and state endangered, smooth coneflower (Echinacea laevigata) and the federal species of concern and state candidate, Carolina birdfoot-trefoil (Lotus helleri). We recommend that the applicant contact the United States Fish and Wildlife Services regarding endangered species issues for commentsQii the scoprng of this project. P. 04 We strongly suggest that the proposed pipeline be located in e)dstrng rights-of-ways where practicable. Should the pipeline parallel any streams, we recommend that the edge of the construction corridor be located a mitnivitun distance of 100 feet from the stream bank. Any stream crossings should be perpendicular and the directional bore method should be utilized. We additionally recommend that disturbed areas be replanted with native-species beneficial to wildlife. We refer the applicant to George Strader, District Wildlife Biologist at (919) 471-1743 for additional information and ideas on appropriate plantings. Direct impacts to aquatic and terrestrial species habitat throughout the proposed area resulting from the construction and maintenance of the pipeline is of concern. Installation of the pipeline can have local adverse effects on water quality and habitat and eontnImte to a decline in aquatic resources. Sedimentation, riparian habitat destruction, streambank destabilization, and thermal pollution due to loss of canopy cover are direct impacts that may result from installation. - Our greater concerns with expansion of infrastructure are the secondary and cumulative impacts from development facilitated by the expansion. The pipeline will facilitate an increase in industrial, commercial, and residential development within the service area. Studies have shown a serious decline in the health of receiving waters when 10-15% of a watershed is converted to, impervious surfaces (Schueler 1994). Additionally, the pollutants (e.g., sediment, heavy metals, herbicides, pesticides, and fertilizers) washed from roads and urban landscapes can adversely affect and extirpate species downstream of developed areas. Additional impervious surface associated with residential, commercial, and industrial development and highway infrastructure results in increase stormwater runoff that can exert significant impacts on stream morphology. This will cause further degradation of aquatic habitats through accelerated stream bank erosion, channel changes, bedload changes, altered substrates, and scouring of the stream channel. Secondary TUE, MAR-06-01 9:11AM DE&S POWER DELIVERY 704 382 0926 Page 3 21 February 2001 ETNG Patriot Extension NCWRC No. P.01.02.01.02 development that follows infrastructure projects causes the loss, degradation, and fragmentation of terrestrial habitats as well. We offer the following recommendations to help address secondary and cumulative impacts associated with this project and to reduce impacts to fish and wildlife resources. 1. Measures to avoid or minimize impacts to sensitive resources, including wetlands, should be implemented during construction. Where impacts to wetlands are unavoidable, we will recommend mitigation of the losses. In addition to providing wildlife habitat, wetland areas perform important functions of flood control and water quality protection. Disturbed wetland areas should be returned to original soils and contours. Plant communities should be re-established that would result in wetland plain community succession into habitat of equal or greater value than the habitat that was destroyed. Temporarily disturbed wetlands should be reseeded with annual small grains appropriate for the season (e.g. oats, millet, rye, wheat, or rye grass) and be allowed to revert to natural wetland vegetation. Crossings of .wetlands and streams should be minimized, located at narrow areas, and made perpendicular to the stream. P. 05 2. In order to minimize stream impacts, while retaining some measure of wildlife habitat, we recommend a 100-foot undisturbed, native, forested buffer along perennial streams, and a 50-foot buffer along intermiUMIt streams and wetlands. Maintaining undisturbed, forested buffers along these areas will minimize impacts to fish and wildlife resources, water quality, aquatic habitat both within and downstream of the project area, and help prevent the extirpation of endangered and threatened species. In addition, wide riparian buffers are helpful in waintaimng stability of stream banks and for treatment of pollutants associated with urban storrawater. Whereas, a grassed buffer, particularly fescue, is a vegetated buffer but will not provide the necessary and highly valuable functions as discussed for forested buffers. 3. In addition to protection of riparian buffers, we suggest that Rockingham County strongly discourage the in-fill o€100 year floodplains for commercial or residential development. This process only increases the potential for flooding to adjacent properties and interferes with the natural hydrologic process of the waterways. It also disrupts the continuity of migration corridors for wildlife. Instead, we recommend that developers set aside a portion of the land to be developed as green, space and concentrate these areas along the streams and rivers. 4. Use bridges for all permanent roadway crossings of streams to eliminate the need to fill and culvert. if culverts must be used, the culvert should be designed to allow for fish passage. Generally, this means that the culvert or pipe invert is buried at least one foot below the natural streambed. If multiple cells are required, the second and/or third cells should be TOE, MAR-06-01 9:11AM DRS POWER DELIVERY 704 382 0926 Page 4 21 February 2001 ETNG Patriot Extension NCWRC No. P.01.02.01.02 P. 06 placed so that their bottoms are at stream bankfull stage (similar to Lyonsfield design). This will allow sufficient water depth in the culvert or pipe during normal flows to accommodate fish movements. If culverts are long, baffle systems are required to trap gravel and provide resting areas for fish and other aquatic organisms. If multiple pipes or cells are used, at least one pipe or box should be designed to remain dry during normal flows to allow for wildlife passage. In addition, culverts or pipes should be situated so that no channel realignment or widening is required. Widening of the stream channel at the inlet or outlet of structures usually causes a decrease in water velocity causing sediment deposition that will require future maintenance. Finally, riprap should not be placed on the streambed. 5. Locate sewers and other utilities as far away from creeks as functionally possible and minimize stream crossings. It is preferable that sewers be located outside the riparian buffers. 6. The construction of roadways in new neighborhoods can produce short-term direct impacts as well as long-term cumulative effects. It is suggested that the County work to limit impervious surfaces to no more than 7%, limit curb and gutter in new developments, and prevent direct discharges of stormwater into streams. Grassed swales in place of curb and gutter, and on-site stormwater management (i.e. bioretention areas) can be installed to produce no net change in the hydrology of the watershed and are recommended. These designs often cost less to install and significantly reduce environmental impacts from residential development. Many of these recommendations have been applied in Maryland in efforts to protect the Chesapeake Bay from water quality degradation. The information provided is not sufficient for our staff to make definitive recommendations or conclusions concerning this project. Due to staff limitations, this standardized response was developed for projects such as this. Although some of the information, requests and comments may not be applicable to certain projects, these guidelines should facilitate preparation of fish and wildlife impact assessments. This information will be very useful if it becomes necessary to prepare an environmental document. In addition to addressing the concerns discussed above, the environmental document should include a detailed assessment of existing natural resources within Haase areas of potential development and should discuss the potential of mitigating development impacts to wetlands, waters and high quality upland habitat. Additionally, to provide a meaningful review of proposed project impacts on fish and wildlife resources, we request that consultants, project sponsors, or permit applicants provide the following information in the environmental document. 1. Include descriptions of fish and wildlife resources within the project area, and a listing of federally or state designated threatexted, endangered, or special concern species.

The Service's comments are submitted pursuant to, and in accordance with, section 7 of the Endangered Species Act (Act) of 1973, as amended (16 U.S.C.1.531 et seq.) and provisions of the Fish and Wildlife Coordination Act (48 Stat. 401, as amended; 16 U.S.C. 661 et seq.). Section 7(a)(2) of the Act requires that all Federal agencies, in consultation with the Service, insure that any action authorized, funded, or carried out by such agency is not likely to jeopardize the continued existence of any Federally-listed threatened or endangered species. The Service is conmued about the potential impacts the proposed action might have on the Federally- endangered smooth coneflower (Echtnacea laevigata). This species is known to occur east of -Eden, in the general vicinity of the proposed project corridor. The Service strongly recommends that ETNG conduct protected species surveys along the sections of the proposed gas pipeline that contain appropriate habitat. Please notify this office with the results of any surveys conducted for this species, including survey methodologies =4 an an;Oyris of the effects. of the action, including consideration of direct, indirect, and cumulative effects. From the preliminary information in your letter, it appears that the project may involve work in wetlands or other waters of the U.S. which could impact fish and wildlife resources.

A description of the fish and wildlife resources within the project area which may be affected directly or indirectly by the proposed project. 2.) A list and acreage of habitat, by cover type, that will be impacted. Wetland types should follow the wetland classification scheme of the National Wetlands Inventory. This list should also give the acreage of each wetland type to be affected by the project as determined by the "Corps of Engineers Wetland Delineation Manual" (Environmental Laboratory, 1987) 3.) A description of the activities that would be conducted in wetlands. 4.) the wetland and other environmental impacts, both secondary and cumulative, that are likely to occur after construction as a direct result of the proposed project and an assessment of the extent to which the proposed project will have secondary impacts and add to cumulative impacts. 5.) Mitigation measures which will be employed to avoid, minimize, rectify, reduce, or compensate for wetland habitat value losses associated with the project. These measures should include plans for replacing unavoidable wetland losses. The Service would not likely oppose the issuance of a permit which would allow work to proceed-, however, we must reserve our determination of whether Federally-protected species will be adversely affected by this project until adequate surveys and a determination of the effects have been provided.

INTRODUCTION East Tennessee Natural Gas Company (ETNG) has conducted cultural resource investigations of the areas where it proposes to develop the Patriot Expansion Project. The investigations were conducted to determine if construction and operation of the proposed project would affect any potential historic properties (including prehistoric sites). ETNG will apply to the Federal Energy Regulatory Commission (FERC) for a Certificate of Public Convenience and Necessity to construct the project. This plan has been written to satisfy FERC's requirement for a plan to address the unanticipated discovery of historic properties or human remains during construction. This document outlines the procedure ETNG will follow to prepare for and address any unanticipated discoveries. It also provides direction to ETNG personnel and their consultants as to the proper procedure to follow in the event that an unanticipated discovery of historic properties or human remains is made during construction. II. TRAINING AND ORIENTATION The Environmental Inspector (EI) will be responsible for advising construction contractor personnel on the procedure 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 El will advise all operators of equipment involved in grading, stripping, or trenching activities to: A. Stop work immediately if they observe any indications 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 El 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 and historic period items) and features (e.g. walls constructed of natural materials such as cobbles, paved surfaces such as by cobbles or brick or other material, other remnants of cultural activity). A. Stop work in the immediate vicinity of the observed cultural materials 1. Notify the El of the discovery 2. If El believes that an unanticipated discovery has been made a) El directs all ground-disturbing activities within 250 feet of the discovery to stop b) El will protect and secure the evidence in place by delineating the find with flagging or fencing B. Minimize movement of vehicles and equipment in area immediately surrounding the discovery. C. El will immediately notify the ETNG Superintendent. -2- D. ETNG Superintendent will immediately notify the designated ETNG and Foster Wheeler Environmental Corporation (Foster Wheeler) contacts by telephone with written confirmation (via fax or overnight mail). (If primary contact cannot be reached, notify the indicated alternate.) ETNG Contact Alternate ETNG Contact Dennis Newcomer Deborah M. Rios Superintendent East Tennessee Natural Gas Co.

Explain why the archeologist believes the resource is not significant and request from FERC permission for construction to recommence, or 2. Describe a scope-of-work for evaluating the significance of the resource and evaluating project effects on it. A request for authorization to immediately implement the work scope will also be made to FERC and SHPO. 3. Invite the TCIA to observe the implementation of any proposed work. 4. All work to evaluate significance and project effects will be confined to the project's area of effect. -5- H. When the evaluation of cultural resources is complete: 1. ETNG will notify FERC and the SHPO by telephone and report the opinion of the project archeologist about the potential significance of the resource. 2. As soon as possible, following the field investigation, the archeologist will provide Foster Wheeler and ETNG a written report describing the results of the fieldwork 3. If the resource is believed to be significant, the archeologist will prepare a proposal for data recovery. 1. ETNG may choose to prepare an analysis of alternatives to data recovery to determine what form of mitigation is preferable. 1. If an alternatives analysis is conducted, ETNG will submit, by fax or overnight mail, the archeologist's report and the alternatives analysis to SHPO, FERC and the TCIA. 2. If proposed mitigation measures may be carried out without being impeded or affected by construction, the submittal to FERC will be accompanied by a request that construction in the area of the discovery be permitted to resume. J. Upon receipt of authorization from FERC, implementation of mitigation measures will begin immediately. 1. ETNG will advise FERC and SHPO when all mitigation measures have been completed. 2. If construction has been halted, ETNG will also request authorization from FERC to recommence construction. 3. If no verbal or written response is received within 48 hours, it will be presumed that FERC has no objections and construction will re-commence. 4. ETNG will submit a summary report describing the results of mitigation to FERC, the SHPO, and the TCIA within 30 days of notification that mitigation fieldwork has been completed. 5. If archeological data recovery is a component of the mitigation plan, a full report will be submitted to FERC, the SHPO, and the TCIA in accordance with a schedule to be established in consultation with FERC. IV. PROCEDURE WHEN HUMAN REMAINS AND/OR POTENTIALLY HUMAN SKELETAL MATERIALS ARE OBSERVED Human remains are physical remains of a human body including, but not limited to, bones, teeth, hair, ashes, and preserved soft tissues (mummified or otherwise preserved) of an individual. Remains may be articulated or disarticulated bones or teeth. A. Workers will treat all human remains with dignity and respect. B. Immediately stop work in the vicinity of an unanticipated discovery involving potentially human remains. C. Immediately notify the EI about the find. -6- D. If the El believes that potentially human skeletal remains have been found, El will stop all ground-disturbing activities within 250 feet of the potential discovery. 1. Protect and secure the evidence of the discovery. 2. Delineate area with flagging or safety fencing 3. Minimize movement by vehicles and equipment in the immediate vicinity of the discovery 4. Limit movement of vehicles in vicinity of the find to the construction right-of- way authorized by ETNG's FERC certificate. E. El will immediately notify the ETNG construction superintendent who will, in turn, immediately notify the designated Foster Wheeler, FERC and SHPO contacts: ETNG Contact Dennis Newcomer Superintendent East Tennessee Natural Gas Co.

Within 24 hours of the discovery, if possible, a professional archeologist will examine the discovery to determine if the remains are human and have an archeological association and, if so, if that association is aboriginal or non- aboriginal. 1. The services of a physical anthropologist or other qualified professional will be retained if the archeologist is unable to determine if the remains re human. -8- G. If skeletal remains are determined not human and there is no archeological association, the individual making the determination will immediately advise the El and/or the ETNG construction superintendent, and construction may resume. 1. The archeologist will submit a letter report including photographs of the discovery site to the ETNG and the Foster Wheeler contacts within 15 business days of the determination. H. If the skeletal remains are not human but are associated with an archeological site, follow the steps described in Section III A through J. 1. If the skeletal remains are human and not associated with an archeological context, the ETNG Construction Superintendent will notify ETNG, SHPO, FERC, the landowner, and the appropriate medical examiner's office (dial 911 by telephone). J. Human remains found in a prehistoric archeological context will be assumed to be aboriginal. If aboriginal human remains are identified (whether or not in an archeological context), ETNG will immediately notify Native American representatives of the TCIA, the Muscogee (Creek) Nation of OK, Seminole Nation of OK, and Absentee Shawnee Tribe of OK, in addition to contacting FERC, SHPO, NPS (if on NPS land) and Foster Wheeler Environmental. K. If human remains are present in an aboriginal archeological context, ETNG will follow the procedures described in Section HI E through J, except as follows: 1. Notifications to FERC, SHPO, NPS and the TCIA, the Muscogee (Creek) Nation of OK, Seminole Nation of. OK, and Absentee Shawnee Tribe of OK as appropriate, will make special note that human remains have been found 2. Notifications to TCIA will request that the TCIA advise ETNG, FERC, NPS and 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 respective county and state. 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 Indian tribes, the results of contacts, and efforts (as feasible) to accommodate the desires of the Indian 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 FERC advises ETNG that it has determined that the remains should be left in place). -9- 4. If FERC, SHPO, NPS or the TCIA advises ETNG, that. a Native American tribe wishes to take custody of any human remains and reinter them on non-tribal lands, ETNG will, if requested, assist in any negotiations between the tribe and the landowner that may be necessary. 5. ETNG will make a good faith effort to accommodate requests from TCIA that they be present during the implementation of mitigation measures related to human remains. Subject to agreements with the TCIA, and if requested to do so by the TCIA, ETNG will offer to compensate a single tribal representative for time spent observing or participating in the removal of 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. L. 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 [no intrusive examination of the immediate area of the remains; proposal 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 SHPO and NPS (if appropriate), that the associated archeological site is not eligible for the National Register of Historic Places, and that no mitigative measures are necessary, the respective medical examiner'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, ETNG will assume that it is authorized to resume construction when the remains have been removed. 4. ETNG will provide FERC with a written report describing the removal activities within 15 business days of the resumption of construction. 1. Proposals for mitigation will include discussion of what steps will be taken to attempt to identify lineal descendants of the deceased. 2. 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 5. Construction within the remaining 100-foot area of the find will be permitted to proceed when the remains have been removed (or when FERC advises ETNG that it has determined that the remains should be left in place). -10- Duke Engineering Ph & Serv/CeS_ A Duke Eaergy Company 19125 North Creek Parkway Thruway Office Building 500 Washington Avenue 400 South Tryon Street Suite 203 290 Elwood Davis Rd., Suite 290 Portland, ME 04103 Charlotte, NC 28201 Bothell, WA 98021 Liverpool, NY 13088 Tel: 207-775-4495 Tel: 704-382-1900 Tel: 425-485-5668 Tel: 315-641-1624 FAX: 207-775-1031 FAX: 704-382-2778 FAX: 425-485-5934 FAX: 315-641-1626 2150 River Plaza Dr. Suite 140 Sacramento, CA 95833 Tel: 916-564-4214 FAX: 916-564-4203
