HomeMy WebLinkAbout029-85 Potomac Edison Company - Opequon District - BackfileEXHIBIT F Review of Historic Properties A review of Frederick County's Department of Planning and Development listings of historic sites was undertaken to determine if any historic properties might be impacted by the construction of the Meadow Brook Substation. These listings were compiled from survey forms and photographs in the archives of the Virginia Landmark Commission. A two-mile radius from the Meadow Brook Substation was considered adequate for ascertaining the degree of impact. All measurements are straight- line distances as measured from U. S. topographic maps. (See attached Exhibit F-1 for map locating the historic properties.) The proposed electric facilities should not be visible from any of the listed historic properties. The rolling terrain, the scattered natural vegetation, and the existing man-made features will minimize any potential visibility. Only three properties, map identification Nos. 1, 2, and 3, are within one mile of the proposed substation. Properties 1 and 2 are located on the opposite side of the Chessie System Railroad and U. S. Route 11 from the substation. Property No. 3 is located in a valley area which maximizes the screening ability of the rolling terrain. None of the historic properties on Exhibit F-1 are on the National Historic Register or listed as a Virginia historic landmark.

Wyatt County of Frederick Department of Planning and Development Box 601 Winchester, VA 22601 i Dear Mr. Wya t;-Vh Attached are four copies of our revision to Site Plan No. 029-85 (Meadow Brook Substation). In order to clarify the identity of facilities within the fenceline of the substation, we have made Drawing No. 408-821 a part of the revised plan. The scale of Drawing No. 408-821 is one inch equal 50 feet. This was done to show the proposed facilities at a scale that would allow an accurate and uncluttered drawing. The original site plan has had the facilities removed and in their place a reference to the ultimate arrangement Drawing No. 408-821 has been made. Any changes in the future should refer to both drawings. Should there be any questions concerning this information, please do not hesitate to contact me.

Hopefully, this letter will explain the additional information that Frederick County must receive to allow these improvements. Potomac Edison has applied for two building permits; one for a 1000 gallon underground fuel tank, and another for a 16 x 24 steel building to house the emergency generator. Our department will sign -off on the permits to allow construction to begin; however, we will also require Potomac Edison to submit revised site plans to show the new improvements. This submittal is necessary, as it is important to keep existing site plans updated for public informational purposes. Please revise Site Plan #029-85 of Potomac Edison (Drawing Number 408-833) to include these improvements and submit four (4) copies of this plan to our department for approval within the next thirty (30) days. We will send you a copy of the approved revision at a later date. If I may answer any questions regarding this letter, please do not hesitate to contact me. Sincerely, Evan A.

Gyurisin: The Potomac Edison Company Part of the Allegheny Power System Downsville Pike Hagerstown, Maryland 21740 .tune 12, 1986 RE: Meadow Brook Substation Application for Pump and Haul At this time, the Potomac Edison Company, in an effort to successfully provide sewage facilities at the Meadow Brook Substation site near Vaucluse, south of Stephens City, desires to proceed with its application to pump and haul. In our previous conversations, we have discussed the inability of the ground at the substation site to pass the health department perk test. We have, therefore, determined that the only satisfactory and economic method of solving the problem to the advantage of the Health Department, County of Frederick and the Potomac Edison Company is to pursue this permit. It is the opinion of the company, that with the normal sparse usage of substation sewage facilities, that the pump and haul system lends itself well to this particular application and that the proposed holding tanks would only require pumping three times per year. With this letter. I would ask you please to proceed with acquiring the signature of Mr. John R. Riley. Jr., County Administrator to the attached documents and permit application.

PE is a public service corporation organized under the laws of the State of Maryland and the Commonwealth of Virginia and furnishing electric service to the public within its service territory in Virginia. PE also furnishes electric service to the public in portions of Maryland and West Virginia. 2. PE's electric system, consisting of facilities for generation, transmission, and distribution of electric energy as well as associated facilities, is interconnected with the electric systems of neighboring utilities, and is a part of the interconnected network of electric systems serving the continental United States. By reason of its operation in three states and its interconnections with other utilities, PE is engaged in interstate commerce. 3. In order to perform its legal duty to furnish adequate and reliable electric service, PE must, from time to time, construct new electric facilities. The need for new electric facilities is directly related to the growth in demand for electricity on PE's system and the greater that growth in demand, the greater the necessity for new capacity in generation, transmission and distribution facilities. 0 0 - 2 - 4. PE is presently experiencing a growth in demand for electricity on its system and, as a result, must construct several new electric facilities. One of the new facilities is the proposed Meadow Brook Substation. 5. The proposed substation is located in Frederick County. The location of the proposed Meadow Brook Substation is indicated on the topographic map attached to this Application as Exhibit A, and on the Frederick County General Highway map attached as Exhibit A-1. PE has owned this site since 1978. 6. The proposed substation is necessary to meet the growth in demand for electricity in Frederick and Warren Counties and for continued reliability of electric service. The necessity is described in greater detail in Exhibit B to this Application. 7. A substation at the proposed location is the best means of meeting the need described in Exhibit B. The factors influencing PE's selection of the location of the substation are described in Exhibit C to this Application. All applicable local permits will be obtained. 8.

The station will be situated in the southern part of Frederick County, Virginia. The area to be served by Meadow Brook is entirely within Virginia with the exception of some small loads in eastern West Virginia which are served through facilities located in Virginia. The station will also provide a backup supply to loads in West Virginia when normal supplies are interrupted. The area is presently supplied by three 138 kV transmission lines from the north. One from the Ridgeley Substation near Cumberland, Maryland; the second from the Millville Substation just east of Charles Town, West Virginia; and the third from the Stonewall Substation which is located near the West Virginia border northeast of Winchester. These three lines supply the Winchester and Front Royal areas as well as the Shenandoah Valley area south to Elkton and Sperryville, Virginia. When the total load in these areas exceeds 300 MW, loss of one of the three 138 kV supply lines will result in thermal overloads on the remaining two lines and cause the voltages to drop to unacceptable levels. Assuming normal winter weather conditions, the 300 MW load level is projected to occur in 1987. (During abnormally severe weather conditions in January, 1985, the area load actually reached the 300 MW level for a brief period.) After 1987, the winter peak load during normal weather conditions is expected to regularly exceed the 300 MW level. The construction of Meadow Brook Substation will avoid the above overloading and voltage conditions. Meadow Brook will be connected to the Mt. Storm -Morrisville 500 kV line and will include one 350 MVA, 500-138 kV, three-phase power transformer which will serve as the bulk power supply source to the area. Power generated on the 500 kV bulk power system will be transformed at the substation and delivered into the 138 kV area transmission supply system, initially over five 138 kV lines, two existing and three to be constructed. The existing line to Ridgely Substation has taps going to the Strasburg and Bartonville Substations. The second existing line terminates at Riverton Substation and will have a tap to the Bartonville Substation. A double -circuit line to be built will terminate at the Double Toll Gate Substation, and a second circuit will be added to the Ridgely line to provide a separate feed to the Strasburg substation. Meadow Brook will be designed for the potential future addition of three 500-138 kV transformers, two 500 kV lines, and five 138 kV lines, should load growth require them. The station will assure an economical and reliable power supply to the Winchester and Front Royal, Virginia areas. The following system and area benefits will be provided by the Meadow Brook 500-138 kV Substation project: Reduce line loadings into the area on existing lines. Increase voltage levels and maintain acceptable levels during contingencies. Reduce power losses. Provide backup to the Dominion Resources (Vepco) Edinburg Substation by way of the Strasburg -Edinburg 138-115 kV interconnection. Provide backup for the loss of transformation at the Bedington 500-138 kV Substation located near Martinsburg, West Virginia. EXHIBIT C MEADOW BROOK SUBSTATION SITING CONSIDERATIONS Meadow Brook Substation is a 500-138 kV stepdown substation. It will have the potential for four 500 kV line terminals, four 500/138 kV transformers and ten 138 kV line terminals. A substation of this size requires a graded area of approximately 600,000 square feet, with a graded slope of 1 to 3%. Potomac Edison purchased a site from John W. Henry (140.5 acres) and William M. Stickley (43.5 acres) for the construction of Meadow Brook Substation in 1978. The location of this site is ideal for a number of reasons. The site is in the area determined to be the electrical load center of the region. The site complies with the Federal Power Commission Guideline, Paragraph 1, in that the site encompasses existing transmission line corridors. One of these is a 200' wide 500 kV transmission corridor between VEPCO's Mt. Storm and Morrisville Substations. The other is a 100' wide 138 kV corridor between Potomac Edison's Riverton and Ridgeley Substations. These two line corridors overlap by 25'. Therefore, Meadow Brook Substation would encompass an existing transmission corridor 275' wide. This is approximately one third of the total area required for the substation. Other reasons why the site is attractive are: 1. There is enough property to accommodate any line structures that may be needed. 2. The site is adjacent to the Baltimore and Ohio Railroad. This will enable a rail siding to be built into the substation for delivery of heavy equipment, the largest of which is a power transformer shipped on a railroad car with a combined weight of approximately 700,000 lbs. 3. The site has an existing 12 kV distribution line on the property which will be used for station service facilities. 4. The site has good access to U.S. Route 11 via Virginia EXHIBIT C - Page 2 - State Road #638 and is northwest of U.S. Route 11 and Interstate 81. 5. Most of the 138 kV lines exit the substation in a northwest or northeast direction. 6. Due to contours, extensive limestone outcroppings, and maximum allowable railroad grade, areas to the west of Vaucluse were determined to be unsuitable. The Company will provide screening of the substation from vehicular traffic on U.S. Route 11 in the area of the existing 500 Kv line crossing. Natural screening from the rolling terrain and vegetation reduces the visual impact from other directions. Meadow Brook Substation Soil Erosion and Sedimentation Control Plan The soils involved in the project of constructing Meadow Brook Substation are of the Carbo and Timberville series. The Carbo series, with a K value of 0.37, is at the bottom range of high erodibility, while the Timberville series, with K values ranging from 0.24 to 0.32, is classified as having a medium erosion characteristic. The average drainage slopes for the area of construction are less than 2%. All cut and fill slopes, as a general standard, are constructed to a 2:1 slope and are planted with crown vetch in accordance with the attached specifications. The yard area will be graded to a maximum slope of 1.5%, and will be covered with crushed aggregate in accordance with the attached Specification MS 2400-1. Percolation is not stopped. The stone acts as an energy dissipater and runoff is retarded. Where required, ditch or culvert outflows will be rip rapped. Filter fence and sediment basin will be installed as indicated on the attached Engineering Drawing No. 408-722. All seeding will be accomplished as stated in the General Criteria of the Virginia Erosion and Sediment Control Handbook which states that crown vetch seeding periods are March 15 to May 1 and August 15 to October 1. Construction is expected to start during April 1986 when timber and other vegetation will be removed and grading will be started in the yard area. Fencing will be installed during October 1986, and seeding will be done during the interim period. The placement of stone aggregate will also be started during the interim period and extend beyond the completion of the fence. The railroad siding will be started during September 1986 and all work affecting soil erosion and its control should be completed by December 1986. All erosion and sediment control measures shall be checked continuously and especially after each significant storm to locate damages and conduct maintenance operations. Other work such as the construction of the control building, structures, and the installation of control cables, switches, breakers, and transformers will be performed into the fall of 1987. In-service date is projected to be December 1987 (see attached Exhibit A). No unusual soil erosion problems are expected; however, should a difficult soil situation occur, Mr. Mark R. Davis, District Conservationist, SCS-USDA, may be contacted for assistance by calling (703) 662-3312. Approved by: J/r P. L. Bros e Transmission Lines Xngineer J.

EROSION CONTROL AND LANDSCAPING CROWN VETCH SEEDING Introduction - With the exception of certain minimum requirements described in following paragraphs, the establishment of a stand of crown vetch shall be done by the Contractor in such a manner that it will meet the guarantee set forth in this specification. All slopes greater than 2:1 and, in some (A) cases, slopes less than 2:1 should be seeded with crown vetch. Grading - Areas where crown vetch is to be established shall be graded to smooth contours. Any irregularities due to erosion or the Contractor's operations shall be corrected before seeding. If there are several areas in a project to be seeded to crown vetch, all adjoining areas shall be graded so that the areas may be smoothly joined whenever possible. Drainage - Banks or other areas which are being graded preparatory to seeding with crown vetch shall be graded in such a manner that there is adequate and satisfactory drainage from the area. Ground Preparation - If the area is covered with weeds, the weeds shall be mowed to not more than 3" from ground level or they shall be sprayed when specified in the Details of Work. Weed spraying shall be in accordance with spray specifications. If weeds are mowed, they shall be removed from the area. If weeds are sprayed, they shall be raked from the area as completely as possible. All debris and unsuitable material such as stones larger than 3" in any direction shall be removed and disposed of. Seed - When crown vetch seeding is specified, the mixture shall be as follows: Crown Vetch, Scarified (var. Penngift) -- 45 parts Ryegrass, Domestic -- 55 parts 100 parts Inoculant - All crown vetch seed must be inoculated prior to seeding. Limestone - Ground limestone shall be applied at the following rate: Ground Limestone - 2 tons/acre - 100#/1,000 square feet Fertilizer - A low nitrogen fertilizer shall be used. Typical recommended fertilizers and their application rates are: 8-16-16 Fertilizer - 500#/acre - 12#/1,000 square feet OR 5-10-10 Fertilizer - 800#/acre - 18#/1,000 square feet • MS 2400-6-Rl Page 2 of 2 Fertilizer and Limestone Application - Both fertilizer and ground limestone shall be distributed uniformly over the area and incorporated into the soil to a depth of 2" by raking, discing, harrowing, or by other approved methods. Seeding - Not less than 1/2 pound per 1,000 square feet of the specified crown vetch formula shall be applied. Mulch - Two types of mulch are acceptable: Turf Fiber (paper mulch), if used, shall be applied in accordance with manufacturer's instructions. Wheat or Oats Straw or Crown Vetch Hay shall be applied in such quantities and anchored in such a manner that the resulting stand of crown vetch will meet the requirements of crown vetch which are stipulated in the guarantee. Guarantee - Because of the slow rate of germination of crown vetch, a satis- factory stand may not develop for at least one year. However, plants of small size should be present after the first growing season. After one year from the date the area is seeded to crown vetch, the Contractor guarantees that there will not be less than two crown vetch plants per any random square yard. If, before a satisfactory stand of crown vetch is established, the surface has become gullied or otherwise damaged, the affected areas shall be repaired, relimed, refertilized, and reseeded as originally specified at no expense to the Company. Instead of reseeding, the Contractor may plant crown vetch crowns. Prepared by: J. F. Wagner Date: June 22, 1973 Rev. 1: May 27, 1983 Approved by: . � �_ Q�— H. E.

Stormwater Detention Drainage Area I Step 1 - Determine allowable release rate QA and select the appropriate graph. The peak discharge method was used to calculate the pre -development and post -development peak flow rates and runoff depths for a 2-year storm. The results were as follows: Pre -development Q = 8.93 cfs V = .8 inch r Post -development Q = 14.02 cfs V = .96 inches r The allowable release rate (Qo) is therefore 8.93 cfs. Q = 8.93 cfs = 272 CSM* ° acres)(I sq. mi.) 6 0 acres *Since Qo is less than 300 CSM for pipe flow, Graph A (Plate 5-18) may be used. Step 2 - Determine required storage volume (Vs) in watershed inches. Since Vr = .96 inches and Qo = 272 CSM, Vs can be read from Graph A (Plate 5-18). V = 0.2 inch s Step 3 - Transform watershed inches to acre-ft.' V = .2 inch x 21 acres = 0.35 acre-ft. = 15,246 c.f. s 12 inc hes ft. Step 4 - The existing pond surface area is 20,400 S.F. at Elevation 754.5. Therefore, the pond elevation will increase less than 9 inches with a 2-year storm to about Elevation 755.2 which should remain within the banks of the pond.

Capacity will be a minimum when the grass is long and unmowed. This condition corresponds to V2 in Table 1.35b. Erosion will be most likely to occur when the grass is short. This condition will correspond to V1 in Table 1.35b. A design based upon Table 1.35b will result in a channel which will have adequate capacity when the vegetation in the channel is long and thick, which will remain stable when the vegetation is short or recently moved, and which will have adequate freeboard for the design flow. Use the following procedure to design a grass -lined parabolic channel based upon Table 1.35b: 1. Determine the required channel capacity, Q. (Peak rate of runoff from the selected design storm.) 2. Select an appropriate grass lining and note the permissible velocity (Vl) from Table 1.35a. 3. Choose the appropriate sheet of Table 1.35b for the channel slope. Using the permissible velocity (VI) and the required capacity (Q), read the top width (T) and the depth (D) for the correct parabolic section. Design a parabolic waterway to be lined with grass -legume mixture which will carry 21.5 cfs on an 0.82% slope. Solution: 1. Q = 21.5 cfs (given) 2. V1 = 4 ft/sec. for grass -legume mixture (from Table 1.35a). 3. From Sheet 4 of Table 1.35b (for 1% slope): Read the top width (T) and depth (D) for Q = 25 cfs and VI = 3.5 fps. T = 8.9 ft.

Broskey Date: 10-1-85 Meadow Brook Substation Soil Erosion and Sedimentation Control Plan The soils involved in the project of constructing Meadow Brook Substation are of the Carbo and Timberville series. The Carbo series, with a K value of 0.37, is at the bottom range of high erodibility, while the Timberville series, with K values ranging from 0.24 to 0.32, is classified as having a medium erosion characteristic. The average drainage slopes for the area of construction are less than 2%. All cut and fill slopes, as a general standard, are constructed to a 2:1 slope and are planted with crown vetch in accordance with the attached specifications. The yard area will be graded to a maximum slope of 1.51/0 and will be covered with crushed aggregate in accordance with the attached Specification MS 2400-1. Percolation is not stopped. The stone acts as an energy dissipater and runoff is retarded. Where required, ditch or culvert outflows will be rip rapped. Filter fence and sediment basin will be installed as indicated on the attached Engineering Drawing No. 408-722. All seeding will be accomplished as stated in the General Criteria of the Virginia Erosion and Sediment Control Handbook which states that crown vetch seeding periods are March 15 to May 1 and August 15 to October 1. Construction is expected to start during April 1986 when timber and other vegetation will be removed and grading will be started in the yard area. Fencing will be installed during October 1986, and seeding will be done during the interim period. The placement of stone aggregate will also be started during the interim period and extend beyond the completion of the fence. The railroad siding will be started during September 1986 and all work affecting soil erosion and its control should be completed by December 1986. All erosion and sediment control measures shall be checked continuously and especially after each significant storm to locate damages and conduct maintenance operations. Other work such as the construction of the control building, structures, and the installation of control cables, switches, breakers, and transformers will be performed into the fall of 1987. In-service date is projected to be December 1987 (see attached Exhibit A). No unusual soil erosion problems are expected; however, should a difficult soil situation occur, Mr. Mark R. Davis, District Conservationist, SCS-USDA, may be contacted for assistance by calling (703) 662-3312. Approved by: 2 P. L. Bros e, Transmission Lines ngineer J.

The results were as follows: Pre -development Q = 8.93 cfs. V = .8 inch r Post -development Q = 14.02 cfs V = .96 inches r The allowable release rate (Q°) is therefore 8.93 cfs. Q = 8.93 cfs = 272 CSM* ° acres (1 sq. mi.) 6 0 *Since Qo is less than 300 CSM for pipe flow, Graph A (Plate 5-18) may be used. Step 2 - Determine required storage volume (Vs) in watershed inches.

Capacity will be a minimum when the grass is long and unmowed. This condition corresponds to V2 in Table 1.35b. Erosion will be most likely to occur when the grass is short. This condition will correspond to V1 in Table 1.35b. A design based upon Table 1.35b will result in a channel which will have adequate capacity when the vegetation in the channel is long and thick, which will remain stable when the vegetation is short or recently moved, and which will have adequate freeboard for the design flow. Use the following procedure to design a grass -lined parabolic channel based upon Table 1.35b: 1. Determine the required channel capacity, Q. (Peak rate of runoff from the selected design storm.) 2. Select an appropriate grass lining and note the permissible velocity (V1) from Table 1.35a. 3. Choose the appropriate sheet of Table 1.35b for the channel slope. Using the permissible velocity (VI) and the required capacity (Q), read the top width (T) and the depth (D) for the correct parabolic section. Design a parabolic waterway to be lined with grass -legume mixture which will carry 21.5 cfs on an 0.82% slope. Solution: 1. Q = 21.5 cfs (given) 2. V1 = 4 ft/sec. for grass -legume mixture (from Table 1.35a). 3. From Sheet 4 of Table 1.35b (for 1% slope): Read the top width (T) and depth (D) for Q = 25 cfs and VI = 3.5 fps. T = 8.9 ft.

Gardner Kimberly Snyder Timothy A. Thompson Abstract In November of 1985, an archeological resources reconnaissance was conducted of the proposed Meadow Brook sub -station in Frederick County, Virginia. This work was conducted by Thunderbird Archeological Associates, Inc. for Allegheny Power Sustem and Potomac Edison. Archival investigations and an historic map search revealed the possible presence of a residential structure in the southwestern part of the study area. This location corresponded to foundation remants observed in the field and designated as Site 1. In addition, two other archeological sines were discovered during the course of the survey. Site 2 consisted of lithic debitage from prehistoric tool manufacturing; no cultural affiliation could be assigned. In addition, a small amount of historic cultural debris was also recovered. Site 3 consisted of a foundation and a chimney fall. This site does not appear on historic maps. Impressionistically, this appears to be the remains of a tenant house or a mill worker. None of the archeological sites were in the area of immediate construction impact, which is located in the northeastern portion of the study area. If construction impact is confined to the northeastern portion of the study area, no additional archeological work is recommended. If the impact extends into the area containing the archeological sites, additional archeological investigations are recommended for the historic components.

L Introduction This report presents the results of a Phase I archeological resources reconnaissance of the proposed Meadow Brook substation in Frederick County, Virginia. The work was conducted by Thunderbird Archeological Associates, Inc. (TAA) for Allegheny Power System and Potomac Edison. Dr. William M. Gardner served as principal investigator on this project and Timothy A. Thompson served as field supervisor. The field and lab crews were drawn from TAA staff. The project consists of the proposed construction of a substation which will be on a tract of land located just off U.S. Route 11 in Frederick County,Virginia (Figure 1). No archeological sites were discovered within the actual construction boundaries (shown as Plant Site on Figure 1), however, three archeological sites were found within the general study area. These are designated as Sites 1-3 on Figure 1. State site numbers have not yet been obtained for these sites, however, once they have been received, an addendum to this report will be issued. All of the sites found within the project area contained historic cultural components and one, Site 1, contained a prehistoric cultural component as well. Environmental Background The project area is located in the section of the Ridge and Valley province known as the Great Valley. The area is underlain by chert bearing limestone and is locally referred to as 'cherty ground'. The chert occurs in both small rounded nodules, apparently replacement, and small rectanguloid linear pieces, apparently from irregular bedded material. The nodular chert appears to be of higher quality and more varied in color, with less flaws or irregularities. None of the material, however, was suitable for manufacture of more than small flake tools or small bifaces ca. 2-4 inches in length and width. The topography can be characterized as the gently rolling topography of the area's limestone terrain. The valley of Meadow Brook borders the site to the northwest and much of the area is a high interfluvial location j overlooking but somewhat removed from the stream valley. Within the L' • Neadat Brat SaUtatiaa - rhme I "rt 2 project area, past streams, active or seasonal, have cut broad and low swales which provide much of the undulation to the topography. It is probable, based on work elsewhere in the Shenandoah Valley (cf. Gardner 1974, 1978), that some of these now extinct streams were active in the Pleistocene but became extinct during the post -Pleistocene increase in evaporation, or else went underground. During periods of heavy rains, these channels probably act as run-off channels. The project locality is currently in pasture with small, discontinuous patches of woods. These woods are generally in areas where the horizontally bedded limestone outcrops at the surface and made plowing difficult or impossible. It is possible that these areas may have been cultivated in the past, but were subsequently abandoned as surface erosion exposed the limestone beds. The age of the trees in the woods is not more than 40-60 years at the most It is also possible that the woods were left as wind breaks, cattle shade areas, or, wood lots. Soil erosion in the uplands here, as elsewhere in the Valley since Euroamerican deforestation and cultivation began in the 1720s to 1750s has been considerable. Test excavations show a shallow sod zone (ca..2 5 inches deep), underlain by a heavy loam plowzone which rests directly on top of extremely old residual clay generally at a depth of between 1.0 to 1.3 feet below the surface. Meadow Brook valley, however, has been the recipient of sedimentation, primarily from slope erosion. Test excavations along the lowest terrace revealed a shallow sod zone, a plowzone, and a gleyed clay horizon. The valley is currently quite poorly drained and swampy, in part as a result of the erosion of the uplands. It is in this setting that the major prehistoric sites occurred. Regional Culture History The following presents a prehistoric culture history applicable to the study area and to the Northern Shenandoah Valley in general. Paleoindian Period ( 500-8 00 B>C>) - This period represents the ErE earliest known inhabitants of the Shenandoah Valley and is characterized by l- a hunting emphasis, although exploitation of available plant resources also occurred. Traditionally, the focus of the hunt was thought to be now -extinct Pleistocene megafauna such as mastodon, mammoth and bison. However, it ` now appears that these species were extinct by the time the Paleoindians arrived in the Valley and that the hunting focus was on more modern species such as moose, elk and deer. The tool kit is geared towards hunting and the processing of hunt by-products such as skins, sinews, etc. A biface and core technology prevailed and the earliest diagnostic of the period is the • 2iaadaw Zr"k S"statiai - ?hmm I "rt '; fluted, lanceolate projectile point type known as Clovis. Later diagnostic styles include Mid-Paleo and Dalton (6500-8000 B. C.). An emphasis on cryptocrystaWne lithic raw materials is evident and the settlement pattern is geared towards the locations of these preferred materials, in addition to poorly drained floodplains with nearby stream junctions (Gardner and Rimmler 1980). The settlement pattern operative at this time consists of household units moving through the Valley, returning periodically to floodplain base camps in order to replenish their tool kits. The nuclear or extended family was probably the basic social .unit during this time period, although larger groups would have gathered at the base camps. it is difficult to say how many households would gather at the base camps, although the numbers would not have been great, as the local environment could not have supported large populations. Early Archaic (8000-6500 B.C.) - Initially the early part of this period is identical to that of the Paleoindian, although this continuity lessens as the period continues. A major change in the tool kit is evidenced by a shift to comer notched points around 8000 B.C. These points are often serrated and basally ground. Point types include Kirk Corner Notched, Palmer Corner Notched and Amos Comer Notched There is a subsequent shift to side notched types and finally to stemmed, slightly indented base points. Other diagnostic points include Kirk Side Notched, Warren Side Notched and Kirk Summed. The shift to notched points indicates a shift from the hand held spear of the Paleoindians to an atlatl or spear thrower. Other additions to the took kit include the flaked stone ax and the drill (Gardner 1984). In the beginning of this period, there is considerable overlap in site choice with the Paleoindian period and the Early Archaic populations favored areas of limestone bedrock. Toward the middle of the period, sites are found '. in areas of shale bedrock and, by the end of the period, there is little overlap E,.. in site choice. In addition, there is some indication of a population increase dureing the Early Archaic. There is an additional shift away from the dependence on cryptocrystalline lithic raw materials. Hunting was still the major subsistence fous but gathering was done as well. y` Middle Archaic (6500-3000 B.C.1 - Although there are some similarities with the Early Archaic, in general, the periods are markedly different. Middle Archaic projectile point styles consist of several different horizons, beginning with the bifurcate forms such as Lecroy and continuing to the post -bifurcate forms such as Stanly, the contracting sum forms such as Morrow Mountain and finally to Guilford and Halifax (Gardner 1964). Adaptive strategies were geared towards general foraging dependent upon seasonal change and hunting played a reduced role. The reduction is • IIeadow Brook sabstatioa - Phase I Report 4 hunting is probably the result of climatic change during this period. There is an overall warming trend which results in the spread of deciduous forests and a reduction of open grasslands (Gardner n.d.). Larger game animals would have been reduced in number as a result of this forest closure, although smaller game animals would have proliferated. The expansion of the deciduous forests was accompanied by an increase in vegetable foods, however, the distribution of these foods was constrained within a horizontal and vertical pattern (Gardner 1978). Site choice was geared to localities which provided access to a wide variety of resources, e.g. multiple habitat zones. The tool kit becomes more generalized, reflecting the change in subsistence patterns. New additions to the tool kit include ground stone tools used to process plant foods and the atlatl weight. The de -emphasis on cryptocrystalline lithic raw materials continues and propinquity seems to be the overriding factor in lithic choice. There is evidence for a significant population increase. Late Archaic (3000-1000 B.C.} -At this time, the points of the Middle Archaic are replaced by broadspears and the steatite or soapstone bowl appears. A preference for quartzite as a lithic raw material is indicated for the broadspear populations (Gardner 1978, 1984). There appears to be two major settlement foci during the Late Archaic: the floodplains and the uplands. The settlement pattern is one of seasonal shifts, depending upon the foods resources available in a given area during a particular season. The Late Archaic is a period of hot and dry conditions which led to an increased productivity in the riverine environment including, in some areas, a radiation in anadromous fish. It also led to a chestnut forest climax, which provided another dependable, albeit seasonal, food resource (Gardner n.d.). A greater degree of sedentism is indicated for the Late Archaic. At between 1600-1200 B.C., perhaps slightly earlier, the Northern Shenandoah Valley witnesses its first major stylistic division. This is manifested in the Susquehanna Broadspears and the narrow bladed Savannah River derivatives. Both forms are actually derived from the earlier Savannah River Broadspear but may have evolved via separate routes. The Susquehanna style zone's southern boundary runs east and west along the Potomac River between the Fall Line near Washington, D.C. to just beyond the edge of the Allegheny Front and the Appalachian Plateau with southern extensions along streams tributary to the Potomac. The relationship between the two groups is poorly known. A riverine orientation with movement toward sedentism characterizes both groups. Some sort of boundary exists because there is little overlap between the two components despite similar adaptations and land use patterns. 2ieadot Brook Sabstation - Phase I Report 3 Woodland - The Woodland period is traditionally divided into three sub -periods: Early, Middle and Late. Although recent research has indicated periods of considerable flux, the changes will be only summarized here. Early Woodland (1000-900 B.C.) - The Early Woodland period is characterized by the introduction of pottery. The earliest type, Marcey Creek Plain, is diagnostic of the Early Woodland I phase. It is characterized by steatite tempering and trough shaped vessels which frequently have mat or basket impressions on the vessel bottoms. At approximately 900 B.C., the beginning of the Early Woodland II phase, the Marcey Creek vessels are replaced by conoidal base, cordmarked forms belonging to the Seldon Island series. The Seldon Island ceramics are also steatite tempered. The Early Woodland III phase is characterized by Accokeek Cordmarked ceramics which consist of sand tempered, conoidal base vessels. Projectile point styles vary but generally consist of stemmed, narrow bladed Savannah River drived points and side notched or fishtail types derived from the Perkiomen-Susquehanna Broadspear styles (Gardner 1982). A general reduction is size is indicated. Early Woodland I -I I I diagnostics are often mixed at sites, indicating a low rate of deposition during this period (Gardner 1982). With regard to Early Woodland settlement patterns, the seasonal shifts of the Late Archiac are replaced by more permanent camps oriented towards the exploitation of riverine and immediately adjacent resources (Gardner and Carbone n.d.), as well as foray camps. Middle Woodland (500 B.C.-AD. 9001 -The Middle Woodland sub - period may be divided into two phases: Middle Woodland I (500 B.C:- AD.300) and Middle Woodland II (AD.300-AD.900). The Middle Woodland is the least well known of the sub -periods however, what is known appears to indicate rapid change. Middle Woodland I is characterized by participation in the Stone Burial Mound Complex phenomenon which begins around 500 B.C. This complex is characterized by clusters of stone mounds located on bluffs ` - overlooking the floodplains. The mounds are piles of stone capping one or more burial pits. Artifacts from the burial mounds include tubular stone _ pipes, platform pipes, copper beads and pendants, copper colts, hematite paint cups, stone colts, bannerstones, projectile points, cache blades and j gorgets (Gardner 1982). Differential placement of mound complexes, t. placement of only certain individuals within the mounds and differential distribution of grave goods within the mounds indicate a degree of socio- cultural complexity not observed previously. Gardner feels that the 2ieadot Brook SKbstatioi - phase 1 Report i development of the Stone Burial Mound Complex may be related to a settlement shift from the levee to the inner filodplain from which backwater swamps may be exploited. Diagnostics of the Middle Woodland I phase include the replacement of grooved axes by celts and small, stemmed points. The ceramics of the Middle Woodland I phase show a gradual evolution from the Accokeek ceramics to the crushed rock tempered Albemarle series. Cordmarked surfaces are more common at the beginning of Middle Woodland I with net marking becoming more common during the latter part of the phase. The Middle Woodland I I phase is very poorly understood. There is a sudden and widespread abandonment of the Stone Burial Mound Complex, however, settlement and subsistence patterns remain unchanged. Projectile point styles appear to be small, contracting stem types similar to Piscataway or Rossville types. In addition, there are traces of corner notched types and pentagonal variants in the late Middle Woodland (Gardner and Carbone n.d.). Woodland I I ceramics are characterized by the replacement of net marked surfaces with fabric impression. There is an indication of a gradual decrease in the amount of crushed rock used as temper with large quantities of crushed rock being replaced by predominantly sand tempered wares with crushed rock inclusions. Late Woodland A.D.{900-AD. 1700) - The Late Woodland sub -period may be divided into five phases: Late Woodland I (AD..900-1100), Late Woodland II (AD. 1100-1250), Late Woodland III (AD.1250-1350), Late Woodland IV (AD. 1350-1450) and Late Woodland V (AD. 1450-1700). It is a period of change marked by population migrations into the Norethern Shenandoah Valley. Triangular points are characteristic of all Late Woodland phases. This indicates the use of the bow and arrow. Late Wwodland I is characterized by a shift around A.D. 900 from the inner floodplain utilized by the Middle Woodland populations to the outer levee of the floodplain. This shift is felt to be reflective of the introduction of agriculture as it represents a shift to more fertile, more easily tilled lands (Gardner 1984). The subsistence system was not enitrely composed of farming, however, as agriculture would have only provided about 25% of the food base and foraging and hunting would have still been necessary to supplement the food base and to obtain other technologically necessary items (Gardner and Carbone n.d.). The Late Woodland I settlement pattern .. appears to be one of dispersed hamlets . The ceramic assemblage is characterized by cordmarked and fabric impressed Albemarle ceramics. Begninning around AD. 1000 is a period of population growth and expansion Headot Brook Sabstatioa - Phase I Report 7 related to the developement of agriculture as a dependable food source. The piopulation growth initially occurred in a linear fashion along the flooplains (Gardner 1984). The Late Woodland I I settlement pattern can be described as a series of hamlets, each containing 6-8 houses, scattered along the floodplain (Fehr 1983). Some degree of relationship between the hamlets is likely. Evidence for the exploitation of a wide variety of resource habitats is indicated by the recovered floral and faunal remains. The Late Woodland II ceramics assemblage is characterized by Albemarle Cordmarked and Fabric Impressed as the dominant series with minor amounts of limestone tempered Page ceramics appearing, as well as incised wares. The incised wares consist of two types: less complex motifs on locally manufactured vessels and complex zoned motifs on vessels imported from the north (Gardner and Carbone n.d.). The Late Woodland I I I phase is characterized by an increased occurrence of limestone tempered (Page) wares. Cordmarked surfaces are dominant and, along with fabric impressed surfaces, are present on both the crushed rock tempered and the limestone tempered series. The incised wares disappear from the ceramic assemblage. Applied rim strips and pseudo collars are present on both series. Decoration on the collars includes cord wrapped stick impressions, gashes and punctations. Gardner hypotheses that the appearance of the Page ceramics in large number reflects actual population migration into the Northern Shenandoah Valley from the south (Gardner 1984). There is. little information on community patterning for this phase, although some indication of larger house sizes may be indicated. Acc retional or floodplain mounds are found near the South Fork headwaters, however, although some are reported to occur in the Northern Shenandoah Valley in early historical accounts, none have been discovered to date (Gardner and Carbone n.d.). The Late Woodland IV phase is characterized by the disappearance of Albemarle ceramics and their replacement by the Page series. Potomac Creek ceramics occur as a minority ware. Surfaces are predominantly cordmarked, although fabric impression is also present. Decorations, when they occur, consist of cord warapped stick stamping on the vessel body, a trait shared with the. Potomac Creek wares. The Potomac Creek ceramics seem to represent another population migration westward from the Potomac Coastal Plain (Gardner and Carbone n.d.). No clear evidence for community patterning is present for the Late Woodland IV phase. ` Neado• Brook s0wtatiea - Phase I Report = At the beginning of the Late Woodland V phase, there is an abrupt appearance of the shell tempered geyser ceramic series and the virtual disappearance of all other ceramic series. The geyser series is characterized by globular vessels with cordmarked, plain or smoothed surfaces; lugs; handles; and rarely, cord wrapped stick stamped and punctate decorations. Gardner feels that the migration of the geyser populations into the Northern Shenandoah Valley is related to environmental change (Gardner 1984). At around AD. 1350-1400, the climate became cooler and drier, causing a contraction of the forests and a spread of the grasslands. A shorter crop season was indicated, accompanied by lower yields. This would result in greater competition for agricultural lands. Hunting would assume greater importance with the radiation in the deer population cause by the expansion of the edge zones. This would result in increased competition over hunting territories (Gardner and Carbone n.d.). One solution to the problem of increased competition would have been migration. Along with the appearance of the geyser ceramic series, a change in settlement patterns is indicated for the Late Woodland V phase. There is a shift from the dispersed hamlet patterns of the preceding periods to a pattern consisting of large, stockaded villages with outlying farmsteads. This contraction of the population and the appearance -of stockaded villages is related to an increase in warfare assumed to be the result of increased competition. Contact Period (AD. 1700-?I - It is difficult t4 present any information on the Contact period as the Northern Shenandoah Valley is assumed to be devoid of aborginal populations at the time of the initial Euroamerican settlement in the area. Only one site from a slightly later time has been excavated. This site, Conrad Cemetary, appears to represent a raid on one of the early European settlements as prehistoric ceramics, historic ceramics, European weapons, harness parts, pig bones and deer bones were found in a hearth. After 1725, historic documentation and place names suggest a number of groups moving through the area: the Susquehannocks, the Shawnee and the Tuscarora. Gardner hypothesizes that the Northern Shenandoah Valley served as a hunting ground or a 'sparsely populated no-man's land' for the Iroquois and other groups (Gardner 1984:24). The cause of the depopulation of the Northern Shenandoah Valley is unclear, although recent research suggests one possibility (Gardner 1984). The increasing importance of the European Fur Trade created inter -group Pe -g P competition for hunting territories from which to obtain these furs. Initially, 4.� raids into the Northern Shenandoah Valley for furs and the disruption of the • Hesdoi Brook Sabstatioi - ?tease I Report indigneous populations were conducted by the Susquehannocks, who were later driven out by the Iroquois (Gardner 1984). It is probable that decimation due to the spread of disease by the Europeans was also a factor in this depopulation. Historic Background - In addition to general background research concerning the project area, a deed search was made of the parcels within the study boundaries. This investigation was conducted at the Frederick County Courthouse and indicated that, with the exception of some small lots at the periphery of and just outside the study area, the property has been part of two large tracts since early in the I M century. These are noted on Figure 1 as Tract A and Tract B. Tract A, a 45.3 acre tract in the northeast corner of the study area, was purchased by Potomac Edison from William Stickley I I I in 1977. This was part of the property that Mr. Stickley inherited from his father, William M. Stickley II, and part of a larger tract that the first William M. Stickley received in a partition between the heirs of Abraham Stickley in 1871. Abraham Stickley had acquired the 390 acre tract (which also included the old stone house at Chrisman's Spring just across U.S. Route 11 from the study area) in 1826, purchasing it from Jacob Stover's estate. Stover had acquired the same tract in 1805, buying it from the estate of Jacob Christman (note change in the spelling of Chrisman) in 1805. Christman had died 30 years earlier and his widow, Mary Magdalena Hite Christman, had continued to live at Chrisman's Spring. Jacob had come to the Valley with Yost Hite, Mary Magdalena's father, in the first quarter of the 18th century and he and Mary were married after their arrival. None of the maps (Lakes Atlas 1885, Hotchkiss Sketch of the Battle of Cedar Creek 1864) of the area that show the locations of residential structures, suggest that Tract A ever contained a house. Field survey also failed to locate any evidence of a structure foundation or concentrations of historic artifacts. Mr. William Stickley also indicated that his own researches and familarity with the property suggest that no structure was ever present. The remainder of the study area was acquired by Potomac Edison from Mr. Henry. He had purchased what we are referring to as Tract B f . (Figure 1) in 1967 from Laura E. Kinter whose husband, Daniel Kinter had L: acquired it in 1951 from the heirs of Warren Rice. Rice had obtained a 143 acre tract, which includes Tract B, in 1930 by sale to settle a court case Laganist Wade H. Guard. Katie J. Guard purchased the tract in 1914 from the estate of A. Wade Muse. Lakes Atlas of 1885 (Figure 2) shows that name next to the location of a structure that is probably identical with the house foundation identified near the southern boundary of the project area, marked as Site 1 on Figure 1. L Headaw Broot SabstaU*a - phase I Export 19 In addition to 'Chrisman's Spring" or 'Indian Spring' estate east of the project area, the Vaucluse plantation on the west is of some historical interest as the home of the "infamous" (translated as womanizing and gambling in early histories) Strother Jones. After the Battle of Cedar Creek in October of 1864, the Confederate Genaral, Jubal Early, retreated to the New Market area. Early in November, he returned to Vaucluse to examine Federal positions between Newtown (Stephens City) and gernstown to the north. As a result of this foray, there were calvary engagements on the Back Road to the west and on the Front Royal Road (presently U.S. Route 340) to the east Jed Hotchkiss' journal and maps (Records of the filar of the Rebellion) indicate that the headquarters were at Vaucluse, west of the project area. The Confederate entrenchments were east of the Valley Turnpike (U.S. Route 11) and the military engagements were some distance to both the east and west of the study area. There is nothing in the maps or the early histories to suggest that there was Civil War activity within the project area, although undoubtedly more than one soldier ran or galloped across the property. Files of earth, sometimes resembling embankments, do occur in the wooded area of the study tract, but these contain rocks of all sizes and are obviously piles left by heavy machinery in field clearing operations. The Valley Turnpike and the Baltimore and Ohio Railroad on the east side of the project area were important transportation corridors during the nineteenth century, but no activities associated with them took place in the project area. Previous Archeological Research - No previous archeological research has been conducted in the project area. Predictive models developed for the Northern Shenandoah Valley indicate that the larger and more permanent sites will be found on the major rivers such as the Shenandoah and its forks. Expected site types at these locations would be base camps from the earlier periods and the hamlets or villages from the later periods. Sites which approximate these in size and !. frequency will also occur with some frequency, according to predictive models, on the lesser order streams in the area such as Cedar Creek, into which Meadow Brook empties. Increasingly smaller and more transient sites will be found on even lower order streams, especially in poorly drained limestone areas. Meadow Brook is a classic example of such a stream. Even smaller and more transitory sites may be found in especially favorable areas radiating out from any of the sites on the varying order streams noted above. The expectations are, for sites along creeks such as Meadow Brook, that the most that will be found in the bordering uplands is an isolated chipping station or a stray projectile point Such sites and finds have limited EE information potential and indeed, often cannot be assigned to a time period Neadow Brook Sabstatioa - ]Phase I Report 11 more specific than prehistoric. Given the presence of plowzones throughout the uplands of the study area and the. intensive erosion, even if such sites area found, they would most likely be redundant with information already acquired and not significant, as well as disturbed somewhat by plowing. Historic period site predictions were covered in some detail in the discussion of the historical background and will not be repeated here. Field Survey Field Investigations were carried out to determine if there were any archeological resources present in the project area that might need further investigation. The first step was to make a complete walkover survey to identify locations susceptible of surface survey and areas where subsurface test units might be desirable. Although none of the project area was cultivated, much of it was in pasture. Cattle trails provided considerable surface exposure in the form of numerous 'transects' crossing the various fields and different topographic settings in the project area. Much of the area was relatively deflated, but a small floodplain was located on the southeast end of the area at the intersection of Meadow Brook and a small, intermittent unnamed tributary, northeast of route 633. The tributary occuppied a small valley extending toward the northeast, and it looked like there was a possiblity of some deposition there, in the form of colluvial wash. Walkover survey revealed the presence of two house foundations and some other interesting topographic features. The first foundation was located just south of the the above -mentioned tributary, about two hundred feet east of route 633 and on the second of two low terraces adjoining Meadow 1.7, Brook. The foundation apears to be the structure labelled on the Lakes Atlas Map as 'A. Wade Muse' (this is discussed further in the background research) and as Site 1 on Figure 1. There is a small rubble -filled basement within a larger depression which apparently represents the outline of the structure. Grass was sparse on the terrace below the foundation and a broad scatter of historic period artifacts, presumably associated with the occupation of the house was present there. Also on this terrace were three round 'humps' of earth about six feet in diameter and about twenty feet apart. A two -foot -by -two -foot test pit was placed just back from the alignment of these features. The dirt from the pit was screened and a number of historic period sherds, a bullet and a noticeable quantity of flakes E were recovered. Site 2 was also discovered by the pedestrian survey. It was a scatter Of mostly historic artifacts, though a few prehistoric flakes were present. It 0 I L Ileadow Brook smbstatiai - rhase I Eeport I z is located on the toe of a ridge which divides Meadow Brook from the unnamed tributary which joins it southwest of the study area. This location overlooks a small, swampy floodplain at the intersection of those two streams. The artifacts were observed in bare areas created by Criss-crossing cattle trails and the soil is deflated. In ephemeral hunting camp and general historic field scatter are indicated, with no likelihood of undisturbed remains, except possibly toward the base of the ridge toe. The third site discovered in the study area is Site 3 which is also an historic house foundation at the edge of the ridge, above Meadow Brook. It is just outside (north) of the study area boundary. The dimensions of the foundation are not clear, but there is a depression filled with water and a chimney fall. Some quite modern looking ceramics were observed next to this feature, suggesting that it may have been occupied in the twentieth century. In addition to the walkover survey which located the three sites, test units were placed in two locations. The small valley containing the intermittent stream was tested to see if there was any deposition which might have preserved occupational evidence. A series of nine shovel tests were placed to cover a cross-section of the valley. No cultural remains were observed -- except for picnic garbage left in the last few years, according to Mr. Henry. The profiles in the shovel tests showed a plowzone that was slightly thicker than elsewhere in the study area, but a well -developed, textured B-Horizon was encountered below the plowzone in each case, indicating a long period of in -situ development without cultural activity. Two test units were also placed in the Plant Site area (see Figure 1) since this location would be subject to primary impact from project construction. The soil was deflated and no cultural remains were observed however. This is likely because the headspring for the small valley has not been active since the end of the Pleistocene, obviating the advantage of this location as a camp site. Another unit was placed near the power line just west of the eastern boundary of the study area, also without result. Summary and Conclusions Background Study and Field Investigations were completed to evaluate the Meadow Brook Substation site. Three archeological sites were identified by the research (one turned out to be just outside the project area boundary), but no archeological or historical resources were present in the Plant Site Area. Numerous surface exposures were available in the study area in the, created by cattle paths, and our first impression was that there appeared to be a noticeable quantity of chert, whose original source would .t 2iea"v Brook Sabstatiai - !base I Report 13 have been outcrops in the limestone bedrock. A careful examination of this material revealed that it was of undesirable quality for the manufacture of stone tools. This observation is reinforced by the fact that the prehistoric artifacts encountered at Site i tended to be of lithic raw material from elsewhere. There were no temporally diagnostic prehistoric artifacts reovered by the survey, but it is likely that further work near the intersection of Meadow Brook with the unnamed tributary would reveal diagnostic material, though the occupations there were likely limited. The foundation at Site 1, the 'Muse Site' suggest the possiblity that significant archeological remains from the historic period might be present there. If ground disturbing activities were planned in this area or the adjacent floodplain, additional testing would be desirable. Neither surface exposures nor sub -surface testing at the proposed Plant Site suggested that there were any cultural resources at or near this location. Background research likewise suggested that there was no liklihood that historic resources were present. Accordingly, no further evaluation for the Plant Site is recommended. ]Meadow Brook Substation - Phase I Report 14 References Cited Fehr, April M. 1983 'Riverine Adaptive Phases and Environmental Stress During the Woodland Period in the Northern Shenandoah Valley'.

This existing network will not adequately and reliably meet the growing demands for electricity. An extensive study was conducted by The Potomac Edison Company to determine alternatives to meet these increasing demands. The study determined the electrical load center for this area is located between Winchester and Front Royal, Virginia, and would be best served from a 500 kV source. The Potomac Edison Company plans to construct a new 500/ 138 kV step-down substation to serve this growing load. The new substation, named Meadow Brook Substation, would be located 2.5 miles south of Stephens City, Virginia, just west of U.S. Route 11 and to the south of Virginia State Road 638. The new substation would be built on a 185acre tract of property purchased by The Potomac Edison Company for this purpose. The site is located beneath an existing 500 kV transmission line. Meadow Brook will tap this line and provide a path for distribution of power from the 500 kV system. The new substation, scheduled to be in service by December 1987, will allow The Potomac Edison Company to continue supplying the Winchester - Front Royal area with reliable electrical service. The enclosed Figure 1 depicts the proposed substation site. • SUBSTATION SITE SELECTION Establishing a substation with a minimum impact requires extensive engineering and planning. Alle- gheny Power System (APS) engineers have applied modern technology to select a suitable substation site which will provide The Potomac Edison Company's Southern Area customers with an adequate supply of electricity now and in the future. ACCESS To every substation, there must be access from the nearest public road. This will be accomplished via Virginia State Route 638, located adjacent to the substation site. A railroad siding will be used for delivery of large equipment. CLEARING AND GRADING The clearing of the substation site prior to grading will be performed in a manner consistent with the conservation of natural resources. Only areas being graded will be cleared and a grading and soil erosion control plan has been prepared. Provisions have been made to control all erosion and sediment with temporary structures and two existing ponds. One small pond, located on the substation site, will be enlarged and used for storm water control. Any disturbed areas outside the substation fenced area will be reseeded promptly. RADIO AND TELEVISION Satisfactory radio and television reception will continue after the substation is placed in service. The Potomac Edison Company's past experience with such stations indicates little need for concern for degradation of reception. However, if instances of degraded radio or television reception occur, the Company, at its cost and with the cooperation of the property owner, will take steps to remedy the situation. SUBSTATION DESIGN An electrical substation is a facility which transforms electrical energy from one voltage to another utilizing special equipment. Meadow Brook Substation will be an open air type 500 kV stepdown substation. It will supply power to the 138 kV transmission system in the Southern Area. i � • 625 INITIAL INSTALLATION (1987 In -Service) 631 STEPHENS� ' C I TY The substation site will be graded to provide for the the Facilities 628 ultimate size of substation. will be as follows: 631 \ 1.
