INTRODUCTIONAND SUMMARY
INTRODUCTION
This document is submitted to the U.S. Nuclear Regulatory Commission (NRC) as an amendment to the Susquehanna Steam Electric Station, Applicants Environmental Report —Revised July, 1972, submitted by Pennsylvania Power 5 Light Company (PPSL). This amendment provides information regarding proposed changes in the EHV electric transmission system associated with the Susquehanna SES; specifically the environmental effects associated with the Sunbury-Susquehanna 500 kV line and the Susquehanna- Siegfried 500 kV line. The EHV electrical transmission system was originally discussed in Section (3.2) of the July, 1972 Report. Changes in that system include: 1) alterations to the Susquehanna-Lackawanna 500 kV line resulting in the Susquehanna-Stanton 500 kV line, and 2) elimination of the Susquehanna-Frackville 500 kV line and replacement with a 500 kV line between the Susquehanna SES and the Sunbury Substation and a 500 kV line between Susquehanna SES and the Wescosville-Siegfried 500 kV line near the Siegfried Substation. The alterations resulting in the Susquehanna-Stanton 500 kV line were addressed in Amendment No. 4 to the July, 1972 Report which was submitted to the NRC on February 6, 1976. The Sunbury-Susquehanna 500 kV line and Susquehanna-Siegfried 500 kV line are addressed in this amendment. Together, Amendments No. 4 and 5 constitute a complete discussion of the 500 kV transmission system for Susquehanna SES. This amendment discusses the environmental characteristics of the lines in conformance with the format established by the NRC Regulatory Guide 4.2, Revision 1, January, 1975. Relevant sections of the Regulatory Guide include: Section 3.9— Transmission Facilities, Section 4.2 —Transmission Facilities Construction, Section 5.5— Effects of Operation and Maintenance of the Transmission Facility, Section 10.9— Transmission Facilities (Alternatives), and NRC Chapter 11 —Summary Benefit-Cost Analysis. These sections are addressed in Parts I I through Vl of this amendment.
SUMMARY
The line routes selected are optimum routes from an overall point of view. The criteria used in their selection included the minimization of right-of-way and construction costs as well as environmental impact. Wherever possible, potential environmental impact was minimized through careful route selection. However, where sensitive environmental features cannot be avoided, appropriate engineering and construction techniques will be employed in order to hold impact at the lowest practical level. The Sunbury-Susquehanna 500 kV line route represents the optimum route environmentally as well as the optimum route economically. Among all of the many alternative routes considered between Sunbury and Susquehanna, this route was identified as having the lowest overall environmental impact. Two principal factors account for the minimum environmental impact associated with the route. First, the route follows a relatively direct path between the terminal points without passing over or near special or highly sensitive environmental features. Second, the route is entirely in parallel with existing or proposed transmission facilities, thus taking advantage of existing access roads and reducing the amount of new right-of-way land required. The directness of the route and the joint use of right-of-way are also primary contributors to the economic advantages of the proposed Sunbury-Susquehanna line. The Susquehanna-Siegfried 500 kV line route minimizes the combined effects of environmental impact, economic cost, scheduling cost, reliability and other factors addressed in Parts V and Vl of this amendment. Other alternate routes were identified which incur somewhat lower potential environmental impacts than the route selected. However, there are considerable economic and reliability advantages of the selected route compared to the route having the least environmental impact. Both right-of-way acquisition and scheduling cost savings are realized by the use of existing right-of-way easements which form the selected line route. Mitigative measures will be taken during construction and operation of the line in order to minimize any potential impacts inherent with the selected route. PART II

THE PLANT
3.9 TRANSMISSION FACILITIES
3.9.1 The Susquehanna 500 kV System
Through further detailed analysis subsequent to the July, 1972 Report, it was determined that the reliability of the previously planned bulk power transmission system was inadequate without the network addition of a 500 kV line from Lackawanna 500 kV substation to the existing 500 kV system in northern New Jersey. This line, which would have been jointly owned with two other Pennsylvania-New Jersey-Maryland (PJM) utilities, was approximately 75 miles long and was expected to be placed in service by 1982 to provide overall improvements in the reliability of the PJM bulk power network. In late 1974, the planned development of the PJM bulk power network was altered due to changing patterns of load growth and capacity expansion of other companies. As a result, the subject line will not be installed. Without this line a single contingency failure of the Susquehanna-Frackville 500 kV line would cause electrical instability of the Susquehanna generators and would necessitate restricting output of the Susquehanna SES. In order to obtain an adequate level of reliability the previously planned transmission system for Susquehanna SES was modified. The presently planned 500 kV transmission lines emanating from the Susque- hanna 500 kV Switchyard consists of the Susquehanna-Siegfried and Sunbury-Susquehanna 500 kV lines. The Susquehanna-Stanton 500 kV constructed line will be operated initiallyat 230 kV to provide reliable supply to the northeast portion of the PP&L system and to provide necessary transmission outlets for Susquehanna Unit No. 1. This proposed transmission for Susquehanna SES, together with the planned PP&L bulk power network will provide an adequate level of reliability. This network will satisfy the reliability criteria of both the Pennsylvania-New Jersey-Maryland Interconnection and Pennsylvania Power & Light Company.
3.9.2 Physical Characteristics Of The Transmission Facilities
3,9.2.1 Description OfSubstations a) Sunbury Substation The Sunbury-Susquehanna 500 kV line will terminate at the Sunbury 500-230 kV Substation. The existing 230 kV portion of the station terminates five 230 kV lines, two
3.9-1 150 MVA, 230-66 kV transformers, and the existing 135 MW Sunbury No. 4 generator. The new Sunbury 500 kV portion of the station will terminate two 500 kV lines and one 650 MVA, 500-230 kV transformer. The Sunbury-Susquehanna 500 kV line will terminate through one 500 kV, 3000 amp circuit breaker connected to the Sunbury 500 kV bus. The existing Sunbury-Juniata 230 kV line (500 kV construction) will be operated at 500 kV and terminate on the Sunbury 500 kV bus. The primary side of the 500-230 kV transformer will connect to the end of the bus, and the 230 kV side will connect to'the existing 230 kV portion of the Sunbury Substation. b) Siegfried Substation The Susquehanna-Siegfried 500 kV line will connect to the existing Siegfried-Wescosville 500 kV constructed line and thus form a Susquehanna-Siegfried- Wescosville 500 kV circuit. A Siegfried 500 kV Substation will not be required for Susquehanna generation. However, system developments not related to Susquehanna will require the development of the 500 kV portion of the Siegfried Substation in the future. The 500 kV switchyard will be capable of terminating four 500 kV lines and two 650 MVA, 500-230 kV transformers. The existing Siegfried 230-66 kV Substation consists of five 230 kV lines, three 150 MVA,230-66 kV transformers and fifteen 66 kV lines.
3.9.2.2 Description Of Transmission Line Structures
Design criteria for the transmission line structures include consideration of aesthetics, reliability, economics', and safety. The proposed structure will be a tubular steel H-frame, internally braced. The height of the structures will average 115 feet permitting .li. ground clearances which will minimize any electrical environmental effects for average spans of 1200 feet. To minimize visual impact, the 500 kV structures will be fabricated from maintenance-free weathering steel, which darkens naturally to a russet brown color. This color blends with leafless trees during winter months and the structures are screened by leaves during summer months. The 500 kV lines near the Susquehanna SES will have structures painted a medium green to harmonize with the 230 kV structures in that area. For the first 4.2 miles from Susquehanna SES, the Sunbury-Susquehanna 500 kV line will be constructed on one circuit position of a double circuit tubular steel H-frame structure. The configuration of this structure will be four phase positions on the bottom cross arm and two phase positions on the top cross arm. The height of the structure will average 155 feet. The second circuit position will be used for future system development.
3.9.2.3 Description Of Basic Design Parameters
The transmission lines have been designed in conformance with the requirements of the National Electrical Safety Code and sound engineering principles. a) Voltage The lines will be constructed and insulated for operation at a maximum phase-to-phase voltage of 550 kV as an effectively grounded system.
3.9-2 b) Capacity Under Normal And Emergency Loading Conditions'he lines are designed to operate safely under a maximum normal current of 3470 amperes (3005 MVA) at 100'C and a maximum emergency current of 4360 amperes (3775 MVA)at 100'C. c) Conductor Type And Configuration The conductor for the lines will consist of two subconductors per phase spaced eighteen inches apart in a horizontal configuration. The subconductor spacing will be maintained by mechanical spacers installed at a sub-span spacing adequate to maintain the eighteen inch spacing. The conductor size will be -2493 kcmil 54/37, Aluminum Cable Alloy Reinforced (AGAR) utilizing 54 strands of EC grade aluminum and 37 strands of 6201 aluminum alloy for reinforcement. Conductor supporting devices, accessories and hardware have been specifically designed to coordinate with the voltage level and to minimize any electrical environmental effects. All conductor supporting assemblies have been tested electrically to insure proper performance under expected in service conditions. Two shield wires will be installed above the three phase conductor bundles for lightning protection. The shield wire size will be 19 No. 9 aluminum clad steel tensioned to coordinate with the sag of the phase conductors. The shield wires will be positioned to provide a maximum positive shielding angle of 20'with respect to the outside phases of the 500 kV circuit. Each structure will be adequately grounded to insure that the structure remains at ground potential. The grounding systems will be tested for adequacy during the construction of the line. d) Ruling Spans The conductors and shield wires will be installed based on a ruling span between angle or deadend (strain) structures. The tension limits on the conductor and shield wire at the installed ruling span will be established to protect the cables from vibration or mechanical damage under the climatic loading conditions anticipated over the life of the transmission line. e) Electrical Clearances The conductors will be installed to maintain adequate clearance over roads, railroads, power lines and communication lines in accordance with the requirements of the National Electrical Safety Code (Sixth Edition) and to maintain acceptable levels of radio influence, television influence, audible noise, electrostatic and electromagnetic fields. Clearances will be maintained at the maximum thermal operating limitof the conductor of 100'C (212'F).
3.9-3 3.9.3 Environmental Characteristics Of The Line Route
3.9.3.1 Geographical Location Of The Line Routes
From a general analysis of the environmental patterns within the region, a 1,050 square mile Sunbury Study Area and a 1,210 square mile Siegfried Study Area were defined to encompass all potential transmission line routes between the Susquehanna SES and the respective Sunbury and Siegfried terminal points. The locations of the two study areas within the region are indicated in Figure 3.9-A. Each study area was delimited on 1:24,000 scale data base maps. The topographic characteristics of the two study areas are shown in Figure 3.9-B. a) Sunbury-Susquehanna Line Route The Sunbury-Susquehanna 500 kV line traverses approximately 44 miles from the Susquehanna SES to the Sunbury Substation southwest of Sunbury, Pennsylvania. Leaving Susquehanna SES, the route crosses the Susquehanna River in a southerly direction and intersects the existing Sunbury-Susquehanna 230 kV route. From this intersection the route parallels the existing line. The two lines parallel the Susquehanna River in a southwesterly direction as they cross, parts of Columbia, Montour and Northumberland Counties. At a point 1.2 miles south of Sunbury, the lines cross the Susquehanna River to the Sunbury Substation on the west bank in Snyder County. The line route is shown in relationship to major geographic features in Figure 3.9-C. b) Susquehanna-Siegfried Line Route The Susquehanna-Siegfried 500 kV line traverses approximately 54 miles from the Susquehanna SES to an interconnection with the existing Wescosville-Siegfried 500 kV line near the Siegfried Substation north of Northampton, Pennsylvania. In exiting the plant, the Susquehanna-Siegfried route parallels the Sunbury-Susquehanna 500 kV line across the Susquehanna River to an intersection with the existing Sunbury-Susquehanna 230 kV line. At this point, the Susquehanna-Siegfried line parallels an existing 230 kV line northeast to a point near Council Cup. At Council Cup the line leaves the existing 230 kV line forming a new right-of-way in an easterly direction across the southern portion of Luzerne County and south into Carbon County. The route then passes in a southeasterly direction across a portion of Carbon County to an intersection with an existing 66 kV line. At this intersection the line and the 66 kV line form a parallel right-of-way south toward East Palmerton Substation. East of the substation the Susquehanna-Siegfried line joins the existing Siegfried-Harwood 230 kV line and continues in a common corridor south to the Wescosville-Siegfried 500 kV line on the Lehigh River in Northampton County. The line route is shown in Figure 3.9-C.
3.9.3.2 Right-of-Nay Data
The Sunbury-Susquehanna right-of-way occupies approximately 928 acres of additional land, utilizing a portion of the existing Sunbury-Susquehanna 230 kV line in its
3.9-4 width. The Susquehanna-Siegfried line occupies approximately 1,237 acres of land. Table 3.9-A shows right-of-way length, width, and area data by segments of the Sunbury-Susquehanna and the Susquehanna-Siegfried lines.
3.9.3.3 Terrestrial And Aquatic IVildlife
The species of terrestrial and aquatic wildlife found in the Sunbury and Siegfried study area are many and varied due to the different types of habitat formed by the ridge and valley physiography that occurs in this part of the state. The characteristic steep ridges and valleys with their forests and rushing streams are contrasted by the more gently rolling farmland that is found in Columbia, Montour, and Northumberland Counties in the northwestern part of the study area and south of Mauch Chunk Ridge and Blue Mountain in the southeastern part of the study area. This contrast provides habitat for forest species, open land species, and species which exploit the areas where these two major habitat types meet. General habitat characteristics are indicated on the map in Figure 3.9-C. The Pennsylvania Game Laws (Pennsylvania Game Commission, 1975) group the mammals of the state into several categories. Important game mammals found in the study area include the white-tailed deer (Odocoileus virginianus), black bear (Ursus americanus), eastern cottontail (Sylvilagus floridanus), snowshoe hare (Lepus americanus), gray squirrel (Sciurus carolinensis), woodchuck (Marmota monax), and raccoon (Procyon lotor). Furbearers are represented by the muskrat (Ondatra zibethicus), beaver (Castor canadensis), mink (Mustela vison), striped skunk (Mephitis mephitis), and opossum (Didelphis virginiana). Two mammals which are becoming less prevalent in the state but which may occur in the study area are the bobcat (Felis rufus) and the river otter (Lutra canadensis). The majority of the study area is in the Alleghanian life zone which is a transitional zone between the sub-Canadian life zone to the north and the Carolinian life zone to the south. Due to its location in a transitional zone, the study area provides breeding habitat for both northern and southern species of birds (Poole, 1964). The extensive forest areas support many songbirds such as flycatchers, thrushes, vireos, and warblers; while blackbirds, orioles, finches, and sparrows are common in fields and around agricultural areas. The study area is also located along a major raptor migration route as is evidenced by the thousands of birds that are observed each year at the Hawk Mountain Sanctuary just south of the study area in northern Berks County (Brett and Nagy, 'I973). Game birds are also numerous in this part of the state with turkey (Meleagris gallopavo) and ruffed grouse (Bonasa umbellus) being found in wooded areas and ring-necked pheasant (Phasianus colchicus), bobwhite (Colinus virginianus), and mourning dove (Zenaida macroura) being most common in farming areas. Other popular game birds include the American woodcock (Philohela minor) and several species of ducks and geese. Amphibians and reptiles are represented by the usual complement of salamanders, frogs, toads, turtles, lizards, and snakes. The habitats of these animals range from the dry upland forest to the small farm pond. While usually inconspicuous, these animals play an important role in the functioning of the ecosystem. Since most aquatic habitat found in the study area is stream habitat, many of the fish species present require cool water temperatures with high oxygen levels. Darters are
3.9-5 common in the faster streams with minnows and shiners reaching their greatest numbers in the slower, more sluggish streams and many. reservoirs that have been created within the study area. By far the most important game fish in this area is the trout which lives in the
many miles of designated trout streams (Pennsylvania Fish Commission, 1976) ~ Most of the reservoirs in the area contain pan fish as does the Susquehanna River which is also known for its bass and muskellunge (Esox masquinongy) fishing. All major waterways and water bodies in the region are indicated on the map in Figure 3.9-C. The Pennsylvania Game Commission (1975) lists no birds or mammals as being endangered in the state; however, the U.S. Department of Interior (1975) lists two endangered mammals and one endangered bird whose ranges encompass the study area. These are the eastern cougar (Felis concolor cougar), the Indiana bat (Myotis soda/is), and the arctic peregrine falcon (Falco peregrinus tundrius). The two mammals have not been observed in the study area, but the peregrine has been observed at Hawk Mountain just to the south. Two birds of undetermined status (USDI, 1973), the American osprey (Pandion haliaetus carolinensis) and the eastern pigeon hawk (Falco c. columbarius), have also been observed at Hawk Mountain and can be considered to pass through the study area during migration. The Pennsylvania Fish Commission (1975) has compiled a list of rare and endangered fish, reptiles and amphibians for the state. The bog turtle (Clemmys muhlenbergii) is the only endangered herptile whose range falls within the study area. Two endangered fish, the swamp darter (Etheostoma fusiforme) and the warmouth (Lepomis gulosus), and two rare fish, the bowfin (Amia calva) and the bridled shiner (Notropis bifrenatus), could also occur within the study area. None of these animals which might be found within the study area have been placed on the USDI (1975) endangered species list.
3.9.3.4 Land Cover
While the character of land cover types are similar throughout the region, their relative extent of coverage varies between local areas within the region. The extent of coverage of each land cover type in the major counties of the region are given statistically in Table 3.9-B and are shown geographically for the two study areas on the map in Figure 3.9-C. The Sunbury-Susquehanna line route is approximately 55 percent in crop and pastureland, and slightly more than one-third in forest land. The Susquehanna-Siegfried line route is nearly two-thirds in forest cover and nearly one-third in crop and pasture land.
a) Forest Cover The study area lies within the Ridge and Valley Physiographic province and is comprised of two sections, the Appalachian Mountain Section and the Great Valley Section. The forest within the study area is primarily mixed oak and pine. Other tree species typically found in the region are listed in Table 3.9-C. Because the study area varies in topography, being a series of valleys and ridges, the forest vegetation also varies. In general, the ridges and high plateaus are composed of scrub oak (Quercus i/I'cifoliaf, white oak (Q. a/baJ, red oak (Q. rubaJ, pitch pine (Pinus
3.9.6 rigida) and short-leaf pine (P. echinata). The valleys are composed primarily of red, white and chestnut oaks (Q. prinus), white pine (P. strobus), hemlock (Tsuga canadensis), several species of birch (Betula spp.), red maple (Acer rubrum), and yellow poplar (Liriodendron tulipi fera). The slopes are highly mixed containing a very diverse mixture of hardwoods and conifers. Numerous oaks, red birch (Betula nigraf, white pine, hemlock, pitch pine and white ash (Fraxinus americana) are the dominant species. Pure stands of hemlock are often formed on steep north and east facing slopes, and in wet areas. Red maple is very conspicuous on poorly drained soils. The dominant understory species are azalea and rhododendron (Rhododendron spp.), mountain laurel (Kalmia latifolia), blueberry (Vaccinium spp.), and willow (Salix spp.). American chestnut (Castenea dentata) represents the only unique flora noted in the area. This tree, while somewhat rare, is not endangered and will not be affected by a transmission line.
b) Crop And Pasture Land A major land cover in the study area is crop and pasture land. This land cover is discussed in terms of land use in Section 3.9.3.5 below.
c) Other Land Cover Other types of land cover include urban and suburban developments, surface mining and transportation rights-of-way, and are discussed in Section 3.9.3.5 below.
3.9.3.5 Land Use, and 3.9.3.6 Demography
a) Regional Patterns The most intensive land use activities in the study areas are of commercial and industrial types while the major land consuming uses are agriculture, surface mining and forest reserves. The geographical pattern of these land uses is greatly influenced by the strong physiographic variations within the region. Generally, agricultural activity has developed in the northeast portion of the region throughout the Susquehanna River Valley, in the Lehigh River Valley south of Blue Mountain, and in the smaller valleys which follow the grain of mountain ridges from southwest to northeast. Similarly, surface mining tends to occur in parallel linear patterns where the mineral deposits follow the geological grain of the mountains. Large tracts of mountainous land remain generally forested. Parts of this land are in relatively inactive reserve while other parts, particularly in the northeast, are experiencing public and private recreational development. The more intensive commercial and industrial activities in the region are largely confined to urban settlements along the Susquehanna and Lehigh Rivers, and in the larger mining districts. The trends of commercial development in this region are typical of an automobile oriented society with activity shifting from the smaller rural villages and central cities toward suburban developments surrounding the larger communities and linear highway developments between communities.
3.9-7 Regional land use and demographic patterns are addressed below by county. Population, employment and agricultural data are based on U.S. Bureau of Census data (Census of Population, 1972; Census of Agriculture, 1972; County Business Patterns, 1972). Other land use data are based on state (Pennsylvania Department of Commerce, 1972) and individual county reports (see Section 3.9 —References, by county). General land use and demographic patterns are shown in Figure 3.9-C. Summary statistics on various land use and demographic factors are given in Tables 3.9-8, C, D, E, F, and G.
Northumberland County The 99,190 residents of Northumberland County are distributed over 453 square miles giving the county a density of 219.0 persons per square mile. Average population density for the study areas is 253.2 persons per square mile. Approximately 60 percent of the population resides in communities having populations over 2,500 persons with Sunbury (13,025 persons) and Shamokin (11,719 persons) being the two principal cities. Approximately 4.0 percent of the population are farm residents and another 27.4 percent are classified as rural non-farm. Northumberland County ranks fourth in agricultural land percentage among the counties in the study area with 130,012 acres (45 percent) in this usage. Only 39 percent of the county's 982 farm units are in the category of small general or part-time operations. Among the larger specialized farms, 79 percent are poultry, dairy, or other livestock farms. Most of the agricultural activity in Northumberland County is centered in the northern part of the county along the main and west branches of the Susquehanna River. In Northumberland County 6,600 acres of land are in use by mining activities in the area south of Little Mountain. The county supports a balance of industrial and commercial employment in its 305 industrial and 1,389 commercial establishments. Northumberland County has 9,292 acres of state game land and only 72 acres of state park. Together, this totals three percent of the county's area. Most of these state lands are within the county's 135,300 acres of forest reserve land. In total, forested land covers approximately 47 percent of the county.
Columbia County The population density of Columbia County is 113.9 persons per square mile. There are 55,114 residents living within an area of 484 square miles. Columbia County has 9.1 percent of its population living on farms, the highest percentage in the study area. In addition to the farm residents, a third. of the total population lives in rural non-farm dwellings, and another 14.1 percent in communities having populations under 2,500 persons. There are two communities having populations over 2,500, Berwick and Bloomsburg, with 43.4 percent of the county population almost equally distributed between the two. Columbia County ranks third among the counties in the study areas having land devoted to agriculture with 46 percent of its area (141,962 acres). The dominant orientation of farming in the county is toward dairy production with a secondary orientation toward other livestock. Approximately 46 percent of the county's 1,037 farm units are in the small general and part-time farm category which is slightly above the mean for all counties in the region.
3.9-8 Approximately 51 percent (148,800 acres) of the land in Columbia County is forest land. About 17,300 acres (11 percent) of the county are designated as state game lands. Except for a small portion of Ricketts Glen State Park extending into the county from neighboring Luzerne County, there is no significant amount of state park lands in Columbia County. There is a very limited amount of surface mining activity in the extreme southern portion of Columbia County with five mining establishments operating south of Big Mountain near Centralia. Of the other 217 industrial establishments operating in the county, most are concentrated within urban areas as are most of the county's 714 commercial establishments.
Montour County With the region's smallest area (130 square miles) and smallest population (16,508 persons), Montour County has a population density of 127.0 persons per square mile. This population density is uniformly distributed. While 40.9 percent of the county's population is rural non-farm, another 9.3 percent are farm residents. Danville (6,176 persons) is the only urban place having a population over 2,500 persons within the county. A total of 50,368 acres (61 percent) of the county's 83,200 acres is devoted to farming. Of the 174 larger specialized farming units within the county, 31 percent are dairy farms. The second largest categories are poultry and other livestock with 17 percent of the larger farms in each category. Another 161 farm units are classified as smaller general or part-time farms. Only 36 percent of Montour County is forest covered. Of this there are 1,243 acres of game land and no state parks. The 32 industrial and 783 commercial establishments in Montour County are typically restricted to urbanized areas.
Schuylkill County While both its population (160,089 persons) and its land area (784 square miles) are above the regional average, Schuylkill County has a population density slightly below the average for the study area. About half of the population live in urban places with populations over 2,500 residents. Pottsville is the single largest center with 19,715 persons. The other urban places include Tamaqua (9,246 persons), Shenandoah (8,287 persons), Mahanoy City (7,257 persons), Schuylkill Haven (6,125 persons), Minersville (6,012 persons), Frackville (5,445 persons), and six other communities with populations between 2,500 and 5,000 residents. Of the 57,349 rural residents, 3,705 are farm dwellers. ,Schuylkill County is predominantly (69 percent) forested. Schuylkill County, however, is much less oriented toward public recreation with 1,500 acres of state park land and 17,954 acres of state game land. This is a combined total of 3.9 percent of the county's land area. A total of 18,132 acres of land is occupied by surface mines and related areas. This represents nearly 3.6 percent of the county's land area. Schuylkill County has 20 percent (100,325 acres) of its total land area used for agriculture. Of the county's 832 farm units, 41 percent are small general or part-time farms. Poultry, dairy and livestock farming are the major specialties in the county.
3.9-9 Luzerne County Luzerne is the most populated county in the region and second only to Lehigh as the most urbanized. Luzerne County's 267,507 residents are divided among five communities having populations larger than 10,000 persons and 19 other communities having populations between 2,500 and 10,000 persons. The larger centers include: Wilkes-Barre (58,856 persons), Hazleton (30,426 persons), Kingston (18,325 persons),
Nanticoke (14,632 persons), and Pittston (11,113 persons) ~ With its heavy urban concentration, Luzerne County has the lowest rural orientation in the region with 15.7 percent of the population classified as rural non-farm and 2.4 percent as rural farm. The population density of Luzerne County is 386.3 persons per square mile. Luzerne County's urban centers support 4,208 commercial and 1,320 industrial establishments. Of the industrial concerns there are 38 mining establishments which utilize 28,050 acres or 4.9 percent of the county's total land area. Luzerne County ranks third in forest cover with 68 percent (386,100 acres). The county supports the 1,005 acre Francis Slocum State Park and most of the 13,050 acre Ricketts Glen State Park. The Pennsylvania Department of Environmental Resources proposed a 2,981 acre Nescopeck State Park north of Interstate 80. With its industrial orientation, Luzerne County ranks low in agricultural activity with 13 percent (75,652 acres) of its land area devoted to this usage. Of the 607 farm units in the county, 42 percent are small general or part-time operations. Dairy farming is the single major specialty with 42 percent of the larger specialized farms in this category.
Carbon County With 50,573 persons distributed over 404 square miles, the population density of Carbon County (125.2 persons per square mile) is approximately one-half of the average density for the study region. Over 50 percent of the county's residents live in urban places having populations over 2,500, principally: Lehighton (6,095 persons), Palmerton (5,620 persons), Jim Thorpe (5,456 persons), and Lansford (5,168 persons). While 27.9 percent of the county's population are rural residents, only 1.5 percent are farm dwellers. This county has the least farm residency in the study area. Carbon County primarily consists of forest land (76 percent). Much of this land is utilized for public recreation in the 15,500 acre Hickory Run State Park, the 3,000 acre Beltzville State Park, and 26,900 acres of state game land. There are also plans for a new Lehigh Gorge State Park from White Haven to Jim Thorpe. In recent years, large tracts of forest land in the Pocono area of Carbon County have undergone extensive resort development. Approximately 11 percent of the land area in Carbon County is devoted to agricultural usage with 27,466 acres distributed among 222 farm units. Specialized farms in the county are dominated by poultry and dairy farms followed by other livestock farming. Over half of the farms (59 percent) are small general and part-time farm units. Farming in the county is generally restricted to a narrow valley south of Spring Mountain and a somewhat broader valley between Mauch Chunk Ridge and Blue Mountain. Typically, most of Carbon County's 561 commercial and 2,041 industrial establishments are located within urban centers. The exceptions, however, are the twenty
3.9-10 mining concerns that operate on 4,416 acres (1.7 percent) of the county's land area. Surface mining activities are located in the extreme western part of the county between Tresckow and Beaver Meadows, and along the south edge of Nesquehoning Ridge between Lansford and the borough of Nesquehoning.
Lehigh County Lehigh County supports a population of 255,304 people living on a total land area of 348 square miles. While second to Luzerne County in total population, Lehigh County has a considerably greater population density (733.6 people per square mile) and the most dominant orientation toward a single metropolitan center of all counties in the study area. Lehigh County's principal urban center is Allentown with a population of 109,527 people. Lehigh County ranks second in the study area in percent of land in agriculture. Of the 799 farm units the majority (60 percent) are classed as large specialized farms (dairy and
other livestock) ~ Urbanization and its associated activities play a major role in the land use pattern of Le hi g h County. The county supports 925 industrial and 3,574 commercial establishments. The county ranks lowest among the counties in the study area with 20 percent (43,906 acres) of its area in forest'cover. The county has 3,375 acres of state game land and no state park land. An important recreational feature from a regional and national perspective is the Appalachian Trail which parallels the Lehigh-Carbon and Lehigh- Schuylkill County lines along the crest of Blue Mountain.
Northampton County The 214,368 residents of Northampton County are distributed over 376 square miles giving the county a density of 570 persons per square mile. This is over twice the average density of the entire study area. Approximately 72 percent of the county's population is centered in communities having populations over 2,500 persons with Bethlehem (72,686 persons) being the principal urban center. Approximately 3.2 percent of the population are farm residents and another 24.7 percent are rural non-farm or residents of communities of 1,000 to 2,500 persons. Northampton County ranks high in agricultural land percentages among counties in the study area, with 107,454 acres (44.6 percent) in crop land or pasture. The county has a tendency toward smaller general and part-time farms, with 58 percent of the county's 805 farms in this category. Of the larger commercial farms, dairy farming is the dominant specialty with 45 percent of the farms in this group. Employment in Northampton County is heavily concentrated in the industrial sector, with 74.4 percent of the labor force being employed in the county's 897 industrial establishments. The balance of the 55,583 employed persons work in the 2,569 commercial establishments. Northampton ranks low among the counties in the study area in percent of forested land. 58,523 acres (24.3 percent) of the county remain in forest cover. There are no state parks in Northampton County; however, state game lands make up 1.5 percent
3.9-11 (3,561 acres) of the county's total land area. The Appalachian Trail along the crest of Blue Mountain parallels the boundary between Northampton County and Carbon and Monroe Counties. b) Sunbury-Susquehanna Line Route The Sunbury-Susquehanna line which is 44 miles in length crosses approximately 23.7 miles of open land, most of which is identified as crop or pasture land. Interspersed with open land is an additional 800 feet of orchard and 2.7 miles of small farm woodlot. Except for the land near the base of the line structures, the open land will be available for crop and pasture. The line crosses approximately 15.1 miles of forest land and 1.6 miles of state game lands. The crossing of Interstate 80 near Mifflinville is the only crossing of a major divided highway by the Sunbury-Susquehanna line. In addition, there are 13 primary and secondary roads, 45 light-duty roads and 6 railroads (as depicted on the U.S. Geological Survey Maps) crossed by the line. No residences, public institutions, or registered historical features are crossed by the Sunbury-Susquehanna line. There are 71 residences, 2 churches, a cemetary and 4 commercial or industrial structures within 500 feet of the right-of-way edge. Between 500 and 1,000 feet from the right-of-way edge there are 150 residences, a school and a cemetery. A detailed inventory of 117 environmental factors on or near the line route was performed. A summary by 24 classes is given in Table 10.9-A in Part V of this amendment. c) Susquehanna-Siegfried Line Route The Susquehanna-Siegfried line, which is 54 miles in length, crosses one partially-completed residence having been inadvertantly built on the right-of-way. The right-of-way also passes within 500 feet of 123 existing residences, while another 234 residences Iie between 500 feet and 1;000 feet of the right-of-way edge. There is one cemetery within 500 feet and another cemetery within 1,000 feet of the right-of-way. The right-of-way also passes within 500 feet of six commercial or industrial establishments. The Susquehanna-Siegfried line crosses 36.3 miles of forest land, which includes state game land and state forest lands. The line also crosses approximately 1,200 feet of reservoir (normal pool) in Beltzville State Park. The line crosses an estimated 3,000 feet of proposed state park along the Lehigh River Gorge, involving the crossing of an existing canoe trail and a proposed foot trail along the abandoned Central Railroad of New Jersey right-of-way. The line route crosses the Appalachian Trail which parallels the ridge of Blue Mountain. The Susquehanna-Siegfried line crosses approximately 15.6 miles of agricultural land. This constitutes approximately 29 percent of the total length of line route. Of this, approximately 900 feet are in orchard, 1.9 miles are in small woodlot and 13.5 miles are in crop, pasture and other open land. The Susquehanna-Siegfried line makes three major divided highway crossings. These include a crossing of Interstate 81 north of Nescopeck Mountain, a crossing of Interstate 80 west of White Haven and a crossing of the northeast extension of the Pennsylvania Turnpike near the community of 'Christmans. There are 30 primary and secondary roads, 50 light-duty roads and seven railroad crossings along the line route.
3.9-12 A detailed inventory of 117 environmental factors on or near the line route was performed. These are summarized by 24 classes in Table 10.9-A in Part V of this Amendment.
3.9.3.7 Areas Of Clearing And Structure Removal
a) Selective Clearing Selective clearing of forest cover will be required on right-of-way widths of 200 feet where a line does not parallel an existing right-of-way, and widths of 150 to 175 feet where an existing line is paralleled. Outside the right-of-way, clearing will be restricted to danger trees; i.e., those trees which pose a hazard to line operation. Hence, rights-of-way will not consist of a clear cut swath through wooded areas, but rather, will be areas of very selective clearing.
Sunbury-Susquehanna Line Route The Sunbury-Susquehanna line traverses 17.8 miles of forest cover which will require 175 feet of additional right-of-way adjacent to the existing Sunbury-Susquehanna 230 kV line. This constitutes a total area of approximately 377 acres which will require selective clearing. No structures will be removed by the Sunbury4usquehanna line.
c) Susquehanna-Siegfried Line Route The Susquehanna-Siegfried line crosses approximately 37.9 miles of forest covered land. Of this approximately 33.7 miles of the line is new right-of-way with a typical required width of 200 feet, and approximately 4.3 miles are parallel right-of-way with an average additional required width of 170 feet. Together there are approximately 909 acres of forest land within the right-of-way which are subject to selective clearing. One partially-completed home inadvertently built on previously-acquired right-of-way will be removed before the Susquehanna-Siegfried line is built.
3.9.3.8 Special Features
a) Historical Resources Several historical sites listed with the National Register of Historic Places and the Pennsylvania Historical Site Files are located within the study area as shown in Figure 3.9-C. However, no registered sites are located within one mile of either the Sunbury-Susquehanna or the Susquehanna-Siegfried line routes. The registered historical site nearest the lines is the Union Reformed and Lutheran Church (1833). This site is registered with the State Historical Site Files and is located in Wapwallopen, approximately 1-1/4 miles east of the point where both lines exit the Susquehanna SES.
Archaeological Resources Several archaeological sites listed with the Pennsylvania Historical Site Files are located within the study area. General archaeological zones are shown in Figure 3.9-C. However, no known archaeological sites are located within one mile of either the Sunbury-Susquehanna or SusquehannaSiegfried line route.
3.9-13 3.9.3.9 Geo/ogy
a) Regional Patterns The study area lies entirely within the Ridge and Valley or Folded Appalachain Physiographic Province (Fenneman, 1938). Some of the valleys make up the Northern,
I Middle Western, and Southern Anthracite Coal Fields of Pennsylvania. In the southeastern corner of the study area is a portion of the limestone floored Great Valley section of the Ridge and Valley Province. Within the study area bedrock ranges in age from Ordovician to Pennsylvanian. Bedrock units are summarized in Table 3.9-H and the distribution of these units is shown on Figure 3.9-D. Economically, the most important bedrock formations in the study area are the post-Pottsville coal-bearing formations of Pennsylvanian age. Almost the entire study area was covered by glacial ice at some time during the Pleistocene Epoch. The boundaries of glacial deposits from three different glacial stages, Jerseyan, lllinoian and Wisconsin, have been identified by Lohman (1937) and others as shown in Figure 3.9-D. These deposits range in thickness from a few feet to several hundreds of feet. In most of the study area, outside the Wisconsin terminal moraine, the glacial deposits are quite thin or absent except along the major stream valleys. Recent alluvium is another type of surficial deposit occurring in the study area. These deposits are mostly thin and insignificant in this part of Pennsylvania.
b) Sunbury-Susquehanna Line Route The transmission line route originates on the south flank of a rolling anticlinal valley underlain by undifferentiated rocks of the Devonian age Chemung formation, Portage group, Hamilton formation, Marcellus shale, and Onondaga formation. The bedrock in the area is mantled by a varying thickness of glacial drift and alluvial material (Lohman, 1937, PPSL, 1971). After crossing the Susquehanna River, the route roughly parallels the river to the north and Nescopeck Mountain to the south. The rolling to hillytopography of this area is a product of differential erosion of the undifferentiated Devonian rock formations and the Devonian Age Catskill continental group. The route then crosses the alluvial filled valley of Catawissa Creek and subsequently traverses the northwest slope of Catawissa Mountain. From Catawissa Mountain to the Sunbury Substation the route traverses a rolling to hilly, very broad topographic valley, where the minor ridges and hills are the result of differential erosion of the less prominent ridge forming rock formations such as the more sandy members of the Devonian units.
Susquehanna-Siegfried Line Route From the plant site to the Nescopeck Mountain crossing, the route is underlain by undifferentiated rocks of the Devonian age Onondaga formation, Marcellus shale, Hamilton formation, Portage group, Chemung formation and the Catskill continental group. These rocks form a rolling to hillytopography developed on an anticlinal valley. South of Lindberg, the route crosses over Nescopeck Mountain which is composed of the Pocono sandstone. South of Nescopeck Mountain the route enters the anthracite'coal fields east of the major coal producing areas. Bedrock in this area is
3.9-14 predominantly the valley-forming Mississippian age Mauch Chunk formation composed chiefly of red and green shale and sandstone., Approximately 2-1/2 miles northeast of Rockport, Pennsylvania, the route crosses the Lehigh River gorge cut through the Pocono sandstone highlands consisting of Summer Mountain, Bald Mountain and others. After traversing the Pocono sandstone highland the route crosses an area of rolling to hilly topography underlain by the Devonian age formations, plus the Oriskany sandstone, Helderberg limestone, Cayuga group, and the Clinton formation. Approximately 1-1/2 miles east of Aquashicola, the route crosses Blue Mountain, a persistent ridge formed by the Tuscorora sandstone marking the west boundary of the Great Valley section of the Ridge and Valley Physiographic Province. From Blue Mountain to the Siegfried Substation the route traverses rolling to gently rolling topography produced on the Ordovician age Martinsburg formation that consists of fissile carbonaceous shale and slate overlain in some areas by soft sandstone.
3.9.3. 10 Soils
a) Regional Patterns The soils of the study area have generally weathered in place from sedimentary gray-red, or yellowish red shale, sandstone, or siltstone, as well as glacial till and conglomerate. Minor amounts of soil have developed in colluvium and alluvium derived from similar parent materials. The soils generally have a deep, well-drained profile and are acid or strongly acid. Rocky textures predominate throughout the area with common classifications being channery, stony, gravelly or shaley silt loams; and stony, gravelly, or sandy loams. Most of the soils exist on sloping to steep landforms and are usually eroded, sometimes to a severe degree. A map of dominant soil associations is shown in Figure 3.9-E. Generalized soil characteristics are given in Table 3.9-I. The natural agricultural quantities of these soils are generally classified as fair or poor, although limited areas are classified as good, and very minor areas may be considered excellent. The principal agricultural limitations of stoniness and steepness cannot be easily mitigated by improving management techniques. Other problems include erosion hazard, acidity, low natural fertility, shallowness, poor water-holding capacity, and poor drainage. The best soils for farming are the more level phases of the soil associations containing Washington, Mifflinburg, and Hartleton soil series, although proper management is required.
b) Sunbury-Susquehanna Line Route The natural agricultural quality of the soils along this route is approximately 1— 3 percent excellent, 35 —45 percent good, 30 —35 percent fair, and 25 —30 percent poor. The Sunbury-Susquehanna line route crosses a total of 28,700 feet of grade 30 percent or steeper, where the potential for erosion exists. c) Susquehanna-Siegfried Line Route The natural agricultural quality of the soils along the route is approximately 3 —5 percent excellent, 3 —7 percent good, 70 —80 percent fair, and 15 —20 percent poor. The Susquehanna-Siegfried line route crosses a total of 14,500 feet of grade 30 percent or steeper, where the potential danger of erosion exists.
3.9-15 3.9.4 Alternative Line Routes And Selection Criteria
A process was employed to evaluate the environmental impacts for a large number of alternate line routes in detail to identify the environmentally optimum routes. From a general analysis of the environmental patterns within the region, a 1,050 square mile Sunbury Study Area and a 1,210 square mile Siegfried Study Area were defined to encompass all potential transmission line routes between the Susquehanna SES and the respective Sunbury and Siegfried terminal points. The process employed in the analysis of the Sunbury-Susquehanna and the Susquehanna4iegfried 500 kV line alternatives had two objectives: 1) to consider as many routing alternatives as possible, and 2) to consider as many environmental factors as possible for each alternative route. In order to systematically consider a large number of routing alternatives (Objective 1), a computerized network analysis was employed. To address the many divergent factors within the natural and man-made environment (Objective 2), a multi-disciplinary approach to impact analysis and route selection was taken. The principal disciplines represented in the analysis group were: regional and community planning, forestry, aquatic and terrestrial biology, geology and soils, cultural resources, landscape architecture, civil engineering and electrical engineering. The identification and analysis of alternative line routes proceeded in three major phases. Each phase of the process employed a progressively more detailed analysis focused on a correspondingly narrower range of routing alternatives. Phase I —Regional Analysis- was a general study of the overall environmental character of the entire study areas. Phase I I Network Analysis — involved the computer assisted analysis of a large set of environmental factor types within a complex system of alternative routing combinations (i.e., network). Phase III — Final Selection of Alternate Line Routes —was a detailed evaluation of the specific environmental characteristics for a number of alternative transmission line. routes. The three phases of the study are discussed below-in further detail.
3.9.4.1 Phase I —Regional Analysis a) Data Collection In Phase I the interdisciplinary study group collected and reviewed existing literature relating to the natural and man-made environment in the study areas. This literature included state, regional and local planning policy, regional and local environmental data inventories and technical studies on environmental features indigenous to the study. areas. The data gathered were consolidated on the base maps for the two study areas. A field reconnaissance of the study areas was then made by the study group to verify and supplement the data on the base maps. b) Data Constraint Analysis Following the field reconnaissance, the study group identified features and areas representing extremely sensitive environmental zones which would be impacted by a new 500 kV transmission facility. In general, such exclusive zones included: urbanized areas, special and unique natural features, airport and communication facility exclusion zones, and special and unique cultural features.
3.9-16 A final step in this analysis was the delineation of a system of corridor segments (network) which bypassed sensitive zones wherever possible, and restricted unavoidable crossings to the least detrimental passages. Included in the system of corridor segments were possible parallel routings with all existing HV and EHV transmission lines in the study area. The result of the Phase I analysis was a loosely structured network of interconnected corridor segments between the Susquehanna SES and the terminal points.
3.9.4.2 Phase II—Network Analysis
The second phase of the alternative line routing process focused on a detailed quantitative analysis of environmental factors within each segment of the two corridor networks and a comprehensive analysis of all possible routes through each of the networks. There were three basic tasks required in the network analysis: 1) refinement of the environmental network alignments and data base, and field inspection, 2) quantitative inventory of environmental factors along each network segment, and development of relative sensitivity weightings associated with the environmental factor types, 3) determination of the minimum impact path through each of the two networks, and analysis of select alternative line routes. a) Refinement Of The Network And Data Base The areas within each segment of the corridor network were studied on the data base maps and aerial photographs to determine precise optimum alignments of potential rights-of-way within each corridor. Where necessary, additional detailed local data was collected and mapped along each segment of the network. This refinement process resulted in a network of 448 interconnected right-of-way segments or links between the Susquehanna SES and the Sunbury Substation and a similar network of 660 links between the Susquehanna SES and the Wescosville-Siegfried interconnection. These networks are diagrammed in Figure 3.9-F. The two networks were analyzed to determine a listing of environmental factors that were unavoidably crossed by the various network links. Ultimately, the 117 factors summarized in Table 10.9-A (Part V) were identified for consideration. A second field reconnaissance of the two networks was then made by the study group to verify and supplement the data base with respect to the 117 factors along each of the network links. Field inspection indicated further refinements in the initial network alignment and environmental factor list. b) Inventory And Weighting Of Environmental Factors Once precise right-of-way alignments were made for all network links, each link was inventoried to empirically establish the quantity of each environmental factor type in or near the various links. These data were tabulated and coded for computer processing. Next, the-overall sensitivity to environmental impact of each network link was determined as a composite function of the 117 environmental factors inventoried. Since the environmental factors were of dissimilar character and relative sensitivity to impact, it was necessary to weight each factor type in order to convert the inventoried data to a common
3.9-17 measure of impact sensitivity. The weighted data for each factor type were then summed for each link to establish a composite environmental impact sensitivity score on each of the network links. c) Minimum Impact Path Analysis And Alternative Path Analysis After establishing the impact sensitivity of each link of the networks in Step b, it was possible to determine the relative impact sensitivity of any given path through the networks. The impact sensitivity score of a given path was taken as the sum of the impact sensitivity scores of all the constituent links in the path. With a measure of relative impact sensitivity for any given path, various paths could be designated and comparatively evaluated. In order to identify the environmentally optimum path through a network, a, computerized minimum path algorithm was employed. The minimum path algorithm systematically analyzed the weighted networks and identified the single unique path that had the lowest environmental impact score among all possible alternative paths through the networks. In addition to the minimum environmental impact path analysis, alternative paths (pre-selected on the basis of construction and right-of-way acquisition costs) were comparatively evaluated in terms of their respective sensitivity to environmental impact. Detailed environmental data on the various alternative line routes considered in the study are presented in Part V of this amendment.
3.9.4.3 Phase III—Final Evaluation OfAlternate Line Routes
The third phase of the route selection process was more detailed than the first two phases. This phase included a field inspection of the alternative line routes identified in Phase I I. This investigation involved both ground level and helicopter inspection. In this phase the study group updated data on the environmental factors along the alternate routes and recorded significant qualitative deviations from the factor norms. This level of study also involved the analysis of additional environmental factors which could not be quantified in Phase II, such as visual exposure, the crossings of the proposed Lehigh River Gorge State Park and other special features encountered along the route. Finally, the ultimate selections of the Sunbury4usquehanna and Susquehanna- Siegfried line routes were based on comparative economic, environmental and reliability considerations among the various alternatives. These considerations are discussed in Part V (Plant Design Alternatives) and in Part Vl (Summary Benefit-Cost Analysis) of this amendment.
3.9.5 Electrical Environmental Characteristics
The SusquehannaZIegfried and the Sunbury-Susquehanna 500 kV lines are electrically similar except for a short section of the Susquehanna-Sunbury line exiting the Susquehanna SES. This section is approximately four miles in length and is of a double- circuit configuration. From an electrical effects standpoint the only other difference between the lines is the extent to which they will be paralleled by other transmission facilities.
3.9-18 The Sunbury and Siegfried circuits parallel each other for approximately 1.7 miles upon leaving the Susquehanna SES. The Sunbury line continues as one circuit of a double-circuit structure for another 2.3 miles and shares a corridor with the Sunbury-Susquehanna 230 kV line. The Sunbury 600 kV line then makes the transition to.a single circuit structure and continues to parallel the Sunbury-Susquehanna 230 kV line for the remainder of its length. The Susquehanna-Siegfried 500 kV line parallels the Sunbury-Susquehanna 230 kV line for about 0.8 miles in an easterly direction after breaking with the Sunbury- Susquehanna 500 kV line. Approximately five miles north of the Bossard Substation, the Siegfried 500 kV line picks up the Siegfried-Harwood 230 kV line and parallels it to the Siegfried Substation. The structure relationships are shown in Figures 3.9-G and H. Reference distances used in the calculations and plots are referenced as follows: (1) single structure corridor: centerline of structure (2) multiple structure corridors: a point one-half the distance between the centerlines of the structures AII HV and EHV alternating current overhead transmission lines may produce several types of electrical effects resulting from corona, electromagnetic, and electrostatic inductions. In general, the incidence and magnitude of these effects will depend upon the following: (1) line to line voltage (2) conductor type (3) conductor surface condition (4) line geometry (6) meteorological conditions (6) line loading and to a lesser extent on construction and maintenance practices used during and after line construction. The electrical environmental effects which may be produced by corona include: (1) generation of ozone and oxides of nitrogen (2) audible noise emission (3) radio and television influence The electrical effects of transmission line inductions include: (1) electrostatically induced voltages and/or currents (2) electromagnetically induced voltages and/or currents
3.9.5. 1 Corona
Corona is a localized partial electric discharge that occurs when the electric field strength (voltage gradient) on the surface of an energized transmission line conductor exceeds the critical gradient in air. The energy dissipated during corona is derived from the conductors. Consequently, from the viewpoint of the transmission line, it constitutes a loss, commonly known as "corona loss". Corona loss depends upon conductor surface gradient, operating voltage, line design, weather conditions and conductor surface conditions. Corona loss calculations for the proposed lines were made using the base case method for two
3.9-19 probabilities and are shown in Table 3.9-J (EPRI, 1975). Corona during most fair weather conditions is generally small and for all practical purposes is negligible. However, during foul weather conditions, (rain, fog, snow, etc.)'orona is not negligible. In the following subsections, the magnitude of the effects associated with corona for the proposed line design are discussed. Assessment of the anticipated effect on the environment and people is developed in Section 5.5.
3.9.5.2 Ozone And Oxides OfNitrogen
Chemically, ozone is 03, a special type of oxygen molecule containing three atoms. Ozone is produced naturally by lightning discharges and solar radiation reacting with hydrocarbon airborne molecules prevalent over metropolitan areas (Scherer, 1972). Corona can also produce ozone and oxides of nitrogen in the air surrounding the conductor. The production and the diffusion of these effluents depend on corona loss, average conductor height, line orientation in relation to wind direction, wind speed and other meteorological conditions. Man-made production of nitrogen oxides is more difficult because higher energies are required than for ozone production (Frydman, 1972). Consequently production rates of oxides of nitrogen are at least an order of magnitude smaller than for ozone (U.S.D.H.E.W., 1970). Significant naturally produced and man-made levels of ozone and oxides of nitrogen have been measured (Scherer, 1972). These levels are caused in part by the solar induced Atmospheric Nitrogen Dioxide Photolytic Cycle causing maximum levels of ozone of 0.500 parts per million at elevations of approximately 20 kilometers (Ibid). High concentrations of ozone and nitrogen dioxide are produced when the products of incomplete combustion of hydrocarbon fuels (gasoline, coal, etc.) react in the sunlight (Ibid;
Frydman, 1972) ~ Also great quantities of nitrogen dioxide are released in the natural decomposition (bacterial action) of organic matter. Ozone concentrations have been measured as high as 0.240 parts per million in large metropolitan areas (Scherer, 1972). Nitrogen dioxide concentrations have been measured as high as 0.560 parts per million 1-hour average in large metropolitan areas (Frydman, 1972). The State of Pennsylvania has no emission rate standards for transmission lines and none have been reported in the literatures of CIGRE (International Conference on Large Electrical Systems), ANSI (American National Standards Institute), or the IEEE (Institute of Electrical and Electronics Engineers). Therefore in PPSL's uses, the standards that apply for ozone and oxides of nitrogen are the Environmental Protection Agency's Ambient Air Quality Standards. These standards specify limits on the photochemical oxident (ozone) concentration to a level of 0.080 parts per million by volume maximum 1-hour concentration not to be exceeded more than once per year. The EPA has also adopted standards for ambient concentrations of oxides of nitrogen (USEPA, Air Pollution Control Office, 1971). These standards limit nitrogen dioxide concentrations to 100 micrograms per cubic meter (0.05 parts per million) annual arithmetic mean concentration. Extensive field and laboratory investigations have been conducted by several electric utilities and research institutions to determine the level of ozone emissions from
3.9-20 EHV lines. During a one year period from October 1970 to October 1971 a joint field measurement program was undertaken by the American Electric Power Service Corporation (AEP) and the Battelle Memorial Institute for the purpose of determining whether ozone emissions from 765 kV lines would contribute significantly to existing ozone levels (Frydman, 1972). A similar study. was made by the Illinois Institute of Technology and Research during a 19 month period from 1971 to 1972 (Fern, 1974). In addition, laboratory studies instituted by AEP in cooperation with Ohio State University were carried out to determine production and decay rates of ozone at gradient levels equal to or greater than those levels found on practical transmission lines (Sebo, 1972; Roach, 1973). All of the above studies concluded that there are no adverse environmental impacts due to gaseous emissions from transmission lines. An ozone survey conducted by the Environmental Sciences Division of the Oak Ridge National Laboratory obtained measurements at selected points on the reservation including points under a 500 kV transmission line (Auerbach, S.l. 1973). Background levels of 0.02 PPM were recorded with values under the transmission line ranging from 0.021 to 0.034 PPM. On one occasion values as high as 0.230 PPM were measured. This high level was attributed to a temperature inversion. This survey indicates that it may be possible for pockets of ozone to form under meteorological conditions favorable to the formation of temperature inversions. The maximum 1-hour concentrations of ozone have been estimated by analytical methods. Each of the corridor configurations were examined and the results are given in Table 3.9-K for the conditions noted. The maximum 24-hour average of oxides of nitrogen above ambient is given for the left and right edges of right-of-way for each of the corridor configurations in Table 3.9-L.
Section 5.5.1 ~ 1 indicates that the low levels of ozone and oxides of nitrogen produced due to the cumulative effect of both the 500 kV and 230 kV lines are well below the maximum levels recommended by the EPA.
3.9.5.3 Audible Noise
All 500 kV overhead transmission line conductors may be sources of audible noise consisting of crackling sounds, broadband noise and pure tone hum. The type and intensity of this effect depend upon the conductor surface gradient, the conductor surface condition, the amount of moisture on the conductor, and the local meteorological conditions. The following investigation of audible noise emission considers the possible effects on the comfort of the public near the transmission line right-of-way. Crackling sounds are produced during fair weather and foul weather conditions. Except at very high surface gradients, audible noise from transmission lines during fair weather is approximately the same as the surrounding ambient noise. However, during fair weather, conductor surface imperfections, insects, dirt, burrs, scratches and any other sharply pointed particles may be points where the air, normally an insulating medium, is overstressed and locally conducts electricity in the form of a spark, thus causing the crackling.
3.9-21 During periods of wet weather, broadband noise occurs. When the conductor surface is wet, water droplets on the conductor are stressed electrically. When they leave the conductor surface in the form of corona streamers, they also produce the crackling noises. The occurrence and intensity of these noises depend upon the conductor surface condition, the electric field intensity and the number of water droplets and their location on the conductor surface. Pure tone hum is essentially a wet conductor phenomena and is most pronounced during periods of high corona loss. The hum is produced by the movement of the space charges produced by conductor corona. Transmission line audible noise sound pressure levels are expressed in dBA using a standard reference pressure of 20 micronewtons per square meter. The "A" weighted response is similar to that of the human ear and is widely used as a single number rating for audible noise. The highest audible noise emission from overhead lines occurs during heavy rain conditions. Under these conditions, the general ambient noise will greatly increase due to the falling rain. Also under these conditions a reduction in public activity near the line is expected. Lesser audible noise emission from overhead lines occurs during light rain or fog conditions. However, under these conditions there will be no increase in the general ambient noise nor should there be any reduction in public activity near the line. In view of this, audible noise emission during fog or light rain is probably the worst condition. For the purposes of this report, this condition will be called the wet conductor condition.
a) Evaluation Of The Audible Noise Impact On The Environment Evaluation of the corona-produced audible noise from EHV overhead transmission lines depends upon: (1) land use designation for noise control (2) ambient audible noise prior to lirie energization (3) acceptable levels of audible noise emission (4) lateral distance to right-of-way (5) magnitude of transmission line audible noise The transmission line routes generally pass through rural areas consisting of farmland and forests (See Table 3.9-M). Typical ambient audible noise levels along the corridors may be expected to range from approximately 35 dBA in farmland and parkland to more than 45 dBA in industrial and commercial areas. In order to evaluate the impact of transmission line audible noise, the Bonneville Power Administration developed a general guideline based upon public response to transmission line audible noise (Perry, 1972). According to this study numerous complaints may be received if line noise exceeds 58.5 dBA and few complaints will result if audible noise is limited to 52.5 dBA. Figure 3.9-I illustrates in more detail the public response typically to be expected for various audible noise levels in a variety of land use types. The noise criteria is based on the quality of speech communication in relation to the background level and distance between the speaker and stations of 20 feet. The relationships shown in Figure 3.9-J are for young adults with normal hearing, speaking the same dialect. Persons under 13 years of age,
3.9-22 people over 65 years of age, hard of hearing persons, and people communicating with dialect differences are likely to require even quieter conditions.
Audible Noise Analysis Of The Proposed 500 kV Transmission Lines The anticipated audible noise emission from the designs for the 500 kV transmission lines have been estimated using an analytical method for wet conductor conditions and for heavy rain conditions (EPR I, 1975). The anticipated audible noise emissions from the proposed 500 kV corridors are shown in Table 3.9-N. These are the maximum levels that would be expected with the indicated voltage under wet conductor conditions. When the conductors are wet (period of light rain or snow, extended periods of fog), the audible noise from the line will be approximately the level in Figure 3.9-K (Wet Conductor). For periods of heavy rain the audible noise of the transmission lines will be approximately the same levels as labeled Heavy Rain in these figures. As discussed in Section 5.5.1.2 the environmental impact of audible noise from the proposed transmission line is expected to be minimal.
3.9.5.4 Electromagnetic Influence
Corona from overhead EHV transmission lines may also produce electromagnetic influence especially during heavy rain, heavy fog, and other periods of inclement weather. This influence is present over most of the radio communication spectrum and may affect the quality of reception of radio and television signals near the right-of-way. The level of influence is expressed in terms of dB referenced to one micro-volt per meter (dBp). Gap type discharges also produce radio influence. However, these are localized from conductor to line hardware, hardware to hardware, etc., and may be easily and quickly detected. The hardware may then either be repaired or replaced. Also, use of the following practices during the design and construction of the circuit will help to eliminate gap type discharge sources of audible noise: (1) proper selection of major components (2) specify and apply adequate mechanical loading Influence on standard FM broadcast radio reception is generally not a problem. The reasons for this are two-fold: (1) Coro n a generated radio influence decreases in magnitude with increasing frequency and is quite small in the FM broadcast band (88 to 108 MHz), and (2) the excellent interference rejection properties inherent in FM radio systems make them virtually immune to amplitude type disturbances. a) Radio Influence The radio influence (Rl) from the proposed 500 kV lines has been calculated for foul weather conditions (EPRI, 1975). The Sunbury-Susquehanna and Susquehanna-Siegfried transmission lines form various corridor configurations depending on whether they are alone or paralleling other high voltage lines. Five different configurations are shown in Figure 3.9-H.
3.9-23 Of the five different corridor configurations examined, the paralleled 500 kV structures (Section 1-1) represent the highest levels of Rl. This section includes both the Sunbury-Susquehanna line and the Susquehanna-Siegfried line. The maximum level during fair weather at the edge of the right-of-way is 81 dBp occurring at that edge of the right-of- way nearest to the 500 kV d/c line. Rl levels are given in Table 3.9-0 for each corridor section. Fair weather Rl levels are expected to be 22 dBp below foul weather levels (EPRI, 1975). In order to maintain good AM radio reception, a signal to noise ratio of 24 dB is recommended. During fair weather an antenna located at the edge of the right-of-way could be expected to give good reception quality for all those stations having signal strengths of 83 dBp or better. This represents 59 dBp of radio influence during fair weather (81 dBp-22 dB) plus a 24 dB signal to noise ratio. Figure 3.9-L indicates the levels of foul weather Rl with respect to lateral distance for each of the corridor sections examined.
b) Television Influence Television influence (TVI) is generally a visual disturbance in the television broadcast band. It may be seen as bands of speckled interference rolling upwards from the bottom of the screen. The TVI produced by corona is summarized by the Institute of Electrical and Electronic Engineers Subcommittee on Radio Noise as follows: "No confirmed data exists which would in fair weather point to the conductor as a source of interference in the television frequencies" (I EEE, Radio Noise Subcommittee, 1971). However, corona from the proposed 500 kV line during foul weather and times of peak voltages (positive cycle) may produce some measurable television influence known as "Precipitation television influence" where there is moisture on the conductors resulting from precipitation, fog, etc. This precipitation type television influence is a distributed phenomena. There are few methodologies for predetermining precipitation type television influence. An effort has been made to correlate precipitation type television influence with foul weather radio influence. For 500 kV lines precipitation type television influence has been found to be less than 2 percent of foul weather radio influence (29dB above 1
microvolt per meter) at a point 200 feet from the outermost conductor (Clark, 1970) ~ This low value is not expected to cause any significant television disturbance. c) Other Communication Facilities Corona producing electromagnetic interference on communication facilities such as television lines and railroad communications and others will be analyzed on an individual basis, due to the unique problems and solutions associated with each case. PP&L will take necessary measures to reduce electromagnetic interference to acceptable levels.
3.9.5.5 Public Safety
Regardless of voltage class, all overhead, energized, load carrying transmission lines have an associated electric field and magnetic field. These two fields and their effects are virtually independent of each other and may be analyzed separately. To analyze these fields it is necessary to consider two coupling modes: 3.9-24 Electrostatic Induction —voltages induced by energized conductors by capacitive coupling (2) Electromagnetic Induction — voltages induced by current carrying conductors These coupling modes may be capable of causing harm in the following ways: (1) Electric shocks that in themselves may cause physical harm (2) Unexpected, electrically harmless shocks which may cause involuntary responses that may result in unsafe acts a) Electrostatic Induction Effects Electrostatic effects may be present when objects possessing conductive characteristics (including people) are insulated from ground and near an electrically energized overhead conductor. The effects would be caused by electric (electrostatic) fields which surround all energized conductors. The four general techniques which can be used to reduce electrostatic effects are: (1) increasing the distance between the energized conductor and object (2) grounding the object (3) use of shielding (4) proper phase arrangement Extensive research on electrostatic effects has been performed at special test facilities and by various electric utilities. This research has resulted in a number of publications discussing the effects of electrostatic fields on metallic objects, such as fences, gutters and vehicles (IEEE Working Group, 1971; Deno, 1974; Reiner, 1972). Methods for calculating these effects have also been presented. Other research addresses the effects of electric fields and currents in people (Singlewald, 1973; Daziel, 1972; Hubbard, 1973). Safeguards are considered in papers by Hubbard and the IEEE Working.Group on "Electrostatic Effects of Overhead Transmission Lines" (Hubbard, 1973; IEEE Working Group, 1973). The intensity of the electric fields at ground level is expressed in units of kilovolts per meter. It has been determined that an average person will feel a slight tingling sensation when exposed to an electric field having an intensity of 15 kilovolts per meter or greater (Reiner, 1972). This electric field intensity is called the "perception level" or the "threshold of sensation." Dalziel has studied the effects of current on people and has determined that the let-go current is 6 milliamperes (mA) for 99.5% of the women tested and the let-go current for 99.5% of the men tested is 9 mA (Dalziel, 1972). The let-go current is defined as the maximum current a person can tolerate and can still release an energized conductor by using muscles directly stimulated by that current. The proposed 7th edition of the National Electrical Safety Code (232,D,3.C) recommends that the maximum electrostatic short circuit current be limited to 5 milliamperes root mean square (RMS) if the largest anticipated vehicle under the line were short circuited to ground. A large vehicle having the dimensions of 8 feet wide, 44 feet long and 12 feet high located parallel to the transmission line, on dry pavement, and in an electrostatic field of 8 kV/m or less will sustain a short circuit current no greater than 5 mA (Deno, 1974). Thus, in general, for most highway applications a peak electrostatic field of less than 7.5 kV/m would be acceptable. 3.9-25 The Johns Hopkins University conducted a 9-year study on 10 linemen working in close proximity of HV and EHV lines and reported their conclusion: "The health of these 10 men has not been changed in any way by their exposure to HV (345 kV) lines..." (Singlewald, 1973). Another area for concern arises for EHV transmission lines passing close to parking areas or service stations where combustible vapors may be present. It has been reported in the literature that gasoline vapors may theoretically be ignited by spark discharges having an energy greater than 0.25 millijoule (Deno, 1974). Unless vapors are confined, natural wind currents would tend to reduce vapor concentrations so that no ignition problems would exist (IEEE Working Group, 1971). This reasoning is reinforced since not a single case confirming gasoline ignition due to power lines has been reported in the published literature.
, The maximum values of the ground level electrostatic gradient have been analytically determined for the proposed 500 kV lines. The values are shown in Table 3.9-P for the corridor configurations. Figure 3.9-M plots the magnitude of the electric field with respect to lateral distance for each of the corridor sections examined. PPSL presently has approximately 110 miles of transmission line operating at 500 kV with no significant problems reported due to the electrostatic field. With the expansion of the 500 kV system similar operating performance is expected. b) Electromagnetic Induction Effects Any current carrying conductor has a magnetic field. The intensity of this field is directly proportional to the magnitude of the current flowing in the conductor, the length of the conductor, and the power system frequency and inversely proportional to the lateral distance away from the conductor. If this current is an alternating current and the conductor is paralleled by a second conductor a voltage will be induced on the second conductor. Some methods which are of practical value in reducing electromagnetic effects are: (1) increasing the distance between the energized conductor and object (2) grounding the object (IEEE Working Group, 1973) The strength of a magnetic field is commonly expressed in units of Webers per square meter or Gauss. This report will deal in units of Gauss, 1 Gauss being equal to 0.0001 Weber per square meter. Studies have been made and are in progress to evaluate the effects of low frequency magnetic fields on human beings. Two recent studies were made by Johns Hopkins University and the Naval Aerospace Medical Institute (Singlewald, 1973; Beischer, 1973). The study by Johns Hopkins University concluded that no ill effects could be determined due to exposure to high voltage transmission lines. The second study subjected 10 men to fields of 1 Gauss at 45 Hz for periods of up to 24 hours during a 7-day period. This study concluded that there were no effects which could be attributed to the magnetic field. However, 9 of the 10 subjects showed an increase in serum triglycerides within 48 hours after exposure. This could not be definitely linked to the magnetic field.
3.9-26 Electronic pacemakers have been found to show minor temporary rate changes that were clinically insignificant when the patients were exposed to fields of 1.35 Gauss Peak (Symth, 1972; Bridges, 1971). All the pacers remained within clinically safe limits and none of the 53 patients could feel any physical change. For comparison purposes a common heating pad generates a field of 2 Gauss (Beischer, 1973). The IEEE Working Groups in Electromagnetic and Electrostatic Effects of Transmission Lines have prepared a report dealing with problems and safeguards relating specifically to transmission lines (IEEE Working Group, 1973). This paper addresses itself mainly to problems encountered by utility personnel in the maintenance and construction of transmission lines, however, many of the corrective measures have general application and could be applied to fences, irrigation pipe, gas pipelines and other conducting objects. Electromagnetic hazards to the public can be eliminated by increased spacing and proper grounding procedures. The intensities of the electromagnetic fields under the proposed 500 kV transmission lines have been estimated using an analytical method for the maximum loading condition of 3470 amperes per phase. Where the 500 kV line is to parallel the Susquehanna-Sunbury 230 kV- single-circuit horizontal line a maximum load current of 1250 amperes per phase is assumed. The Siegfried-Harwood 230 kV line uses a double circuit structure and a vertical conductor configuration. A maximum loading of 1640 amperes per phase is assumed for this line. The electromagnetic field was calculated at an elevation of 10 feet above ground for each of the corridor configurations. The results of these studies are shown in Table 3.9-Q. At ground level the maximum value occurs for the 500 kV double-structure corridor. Figure 3.9-N plots the magnitude of the field with respect to lateral distance for each corridor section. As discussed in Subsection 5.5.1.4 with the limitations noted, it is the opinion of PPSL that the values of the electromagnetic field calculated for the proposed 500 kV lines are safe for man.
