2.0 INTRODUCTION
2.1 Many of the problems naarv4mied wth storm water drainage arise from unwise land-use. Removing I
, vegetation from slopes, cherGs drainage pettoms, wr.c .;..u..g storm water Sows and creating
! higher peak discharge flows accelerate sou erosion through the action of splash impact on bare soR and the increased velocities d storm water runoff. The increased volume of sol entering drainage channels and conduits reduces the water carrying capacky of the drainage system; decreasing efficiency and promoting flooding. Sol erosion not only wastes a valuable resource but often spots j the landscape. Increased amounts of sediment runoff irto waterways is a rnain contributor towards j water pollution.
2.2 Erosion control should begin before changes in land-use are initiated Before earth-moving l
actMties, the soas, the tepcy.$y, and the proposed change in land-use shodd be studied and a l j plan developed to prevent accelerated sol erosion and sedimentation Appropriate erosion control 4 techniques should be implemented. These may indude the retaining of areas of vegetation, scheduling earth-moving activities in phases, and instkuting temporary and permanent erosion and i sedimentation (,ontrol practices. l 2.3 Pennsylvarua's Clean Streams law (PL 1987, No. 394), prohibits the discharge of pollution to the waters of the Commonwealth whether from industrial or domestic sources (Pa DER 1990). The Pennsylvania Department of Erwironmental Resources (Pa DER), under the Clean Streams Law, requires a soi erosion and sedimentation control plan for every earthmoving activity. Addstionally, a perrrut is required for any earthmovmg activtty 25 acres or more. The fogowing erosion and 3.0 mm

2.4 Erosion and sedimentation control meneures using State guideline recommendations wel be integrated with the isndeosping scheme and made permanent by estabhshing vegetatim cover after the earthmoving actMty is complete.
3.0 SME LOCATION / DESCRIPTION 3.1 SNEC is located about 100 miles east of Pittsburgh and 90 miles west of Harrisburg in the Anegheny Mountams,0.75 mies north of the Borough of Saxton in Liberty Township, Bedford County, P=.-Aa.t (GPUS 1963). The site is situated in the valley of the Raystown Branch of the Junista River, along the east bank, as shown in Exhibit 1. It is located in the northwestem comer of the Broad Top QuadrarWe of the U.S. Geological Survey Mep. The river vaney lies between Tussey Mountain to the west and Terrace Mountain to the east. The river meenders along its watercourse with an overad flow direction to the northeast. The relief from the twer to the ridge tops exceeds 500 feet (Ground / Water Technology, Inc.1981).
3.2 SNEC was butt adjacent to an existing coal-fired generating station. The Company property cuiiv.': : -;- i . ^ y 150 acres. The nucieer factity is located within an approximate 1.1 acre plot as shown in the aerial photograph of Exhibit 2.. Steam produced by the nuclear reactor was transferred to a 10-megewett turbine generator located at the Sexton Steam Generating Station At present, the cool-fire plant has been demolished and SNEC has been donctivated The Control Auxliary bu8 ding, a concrete pad previously supporting an 80,000 gebon capacity water tank, a waste storage area, a waste treatment piart and approximately 1,150 square feet of connecting pipe tunnel have been demolished. Only the reactor containment vessel remains (See Exhibit 3).
4.0 GEOLOGY 4.1 SNEC lies in the Appalachian highlands in the Ridge and Valley Province The Ridge and Vaney Province cornpnses altemate emema*=ns of narrow ridges and broad or narrow vaBeys trending generally northeast. This is a region of altemating hard and soft sedimentary rocks that have been severely folded by lateral c0E+. :: ' i into a series of anticlines and sinchnes, The ridge is of Tuscarora quartzite and smed amounts of pleistocene gravel and recent alluvium are found along the river. Most of the area is underlain by Devonian Strata. In the vicinity of the site, these strata slope approximately 50' to the west.1.myers of shale and sandstone have been found at depths greater then 12 feet below the surface (GPUS 1983). A geologic cross section of the region is shown in Exhibit 4. This geologic cross eartian is drawn at a northwest - southeast orientation and indicates that SNEC is constructed on the limb of a me}or sincline that dips generally towards the east (Ground / Water Technology, Inc.1981).
5.0 SOIL DESCRIPTION 5.1 Split-spoon samples collected during a hydrogeological Irwestigation (Ground) Water Technology, Inc 1981) and samples from hand <iug pits indicate that the sufficial soH is comprised of two types of construction backful (1) wed graded reddish saty fine to coarse sand with some fine to medium gravel and (2) a well graded mixture of ash and cinders. Both of those 15 materials were placed during station construction. Laboratory mechanical analyses were performed on both the saty sands and the ash. The depth of the il generally ranges from three to six feet, although the fIl may be deeper at locations where building construction excavation took place.

SNEC Soil Erosion and Sedimentation Control Plan 0 5.2 Underiying the ful materials is a boulder layer. This layer is generally four to six feet thick and separates the ful motorial from the top of the bedrock. The materini making up the boulder matrix is believed to be silty ciey. The sat and clay were found to be loceitted in the boulder layer and did not appear to be present in the fractured bedrock below that Zone (Ground / Water Technology, Inc.
1981). The actual bedrock underlying SNEC is described as grey to olive brown shales, praywackes and sendstones.
5.3 To obtain a reistive indication of the abtity of the various subourface zones to transport water, fleid permeablity tests were conducted in selected bore holes and laboratory machenical snelyses were performed on construction fel material (Ground / Water Technology. Inc.1981). The red suty sand f5 material was well-graded, containing about 45 percent possing a #200 sieve. The well graded 4 4 nature of the fIl suggests a very low permemb51ty, probably ranging between 10 cm/sec to 10 cm/sec. The ash fut r9etorial, however, is believed to have substartiely greater permeablity then the red sery send m. Actuoi pamembesty values for the ash fel are unevenable since the friable particles may have been altered by the mechanical analysas technique 5.4 in general, the censtruedon fgl and boulder layers were less permeable then the bedrock. Tests indicated that the boukler layer acted as a barrier to the flow of groundwater between the construction 151 and the bedrock (Ground / Water Technology, Inc.1981). The permoeb81ty of the bedrock verted with depth. Results indicated rock permenbetty ranging from moderale values (about 1.06 x 104 cm/sec), to negligible values (no Sow recorded in the test secdons). The highest permeabilty was at the MMar layer-bedrock interface This probably was a function of the weathered, fractured nature of the top of the bedrock.
6.0 RUNQFF 6.1 In the general vicinity of the site surface runoff wIl Row down the sides of the ridges into small streams, such as Shoup Run which transects the Company property, and wul be comed to the river.
Also, some surface water wel flow direc6y to the river. The watershed extending upstroom from Saxton is about 756 square mies. ,
6.2 The SNEC site currently contanns an overland drainage system which directs runoff to the rtver.
Methods of sediment control are described in Section 7.0. ;
)
6.3 The " Rational Method' (Salvoto 1982) can be used to conservatively estimate the discharge Gow from '
the SNEC site restdting from stormweter runoff. The aquathn is as foNow:
Q = A*l*R where Q = Runoff in ft 8/ time period A = Aree in ft2 1 = lmperviousn6es ratio R = Rainleil rate in ft/ time period Assuming the drainage ares (A) of concem is the entire SNEC she (1.148 acres), then A = 50,007 ft .

l SNEC Soil Erosion and Sedimentation Control Plan 0 I The choice of an imperviousness ratio (1) is based on the site having a negligible amount of impervlous cover, vegarmiinn rated as bare to light and a sod consistency ranging from grs.vol to gravel sand mixtures wth sitt and clay compnatinn ranging from high to none (USEPA 1976).
Hence, an average i for the SNEC site = 0.39.
The 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> rnaximum rainfall with a ten-year probabuity of occurrence was found to be 4.5 inches (NOAA 1961) for the Sexton vicinity
, Another approach is to use the average of what is consadored the normal montNy ramielt (NOAA l
1982), This average, for the Saxton vicinity, is found to be 3.04 inches.
Hence, considering a 10-year maximum rainfall event, the total runoff from the SNEC site is l calculated as follows.
O = A*l*R l Q = (50,007 fta(0.39) (.375 ft/24 hours) )
- O = 7,313.5 fta/24 hours i l
3 Using an average montNy rainfall event, the total runoff is estimated to be 4,940.7 ft /mo.
7.0 CONTRQL MEA $ YRS $ DyRING EARTHMOVING AQTIVITIES l
7,1 During earth-moving actMties, the emphasis on erosion control is prevention. Environmental and economic costs are minimized with prevention rather than correction. Key elements towards prevention are:
O Minimtre the area to be disturbed - unnecessary and excessive remwel of vegetation and top sol, etcs or steep slopes increase both the Nkelliood and severity of erosion.
9 Preserve vegetation - avoid unnecessary removal of grasses and other low vegetatiort Vegetation is the best protection against soil erosion. It slows and absorbs surface runoff, binds the soi, and protects the sou surface by dis 6ipating the energy of rainfaN and runoff.
9 Minimize the time of exposure - earthmoving actMties should be scheduled to minimize the time that disturbed soi remains unprotected.
O Gradmg - minimize the need for grading, avoid steep slopes, and folow natural contours to the extent practical 7.2 For those areas where sol disturbance is unavoidable and some erosion likely, or for areas which wel be exposed for an extended time, temporary control measures wel be implemented. Three commonly used methods are:
9 Straw bales or filter fabric fences placed at the toe of slopes to irtercept and detain sediment.
l 9 Seeding - storage pies of sou or areas to be exposed for extended periods may be j stabitzed by seeding with fast growing grasses Sodding also may be practical for drainage l areas.

Other mulches should cover 75% to 90% of the sou area. j l
I 7.3 Numerous other methods or combmetions of methods are avaBable ranging in eWectiveness from temporary to permanent. In general, temporary methods are usueNy designed to detain sediment wh5e permerant methods are designed to stablize sediment. Further detal on these and other methods of erosion control are prrmoed by the Pa DER in reference 11.8.
8.0 PERMANENT CONTROL. MEASURES 8.1 Upon completion of aN earthmoving projects, final site ernhaintian wil be performed in general, this will Irwolve mulcNng and/or seeding with perennial grasses or legume vegetation. If applicable, pavement and/or stones may be applied.
8.2 A permanent vegetative cover wW be established on bare soE areas. Seeding wW be made immediately after final land shaping or gradmg is completed, or as soon thereafter as seed germmation we occur. A permanent vegetative cover also wGl be established on areas where earthmovmg operations wtl be delayed for an extended period Due to the near horizonts' grade of the SNEC site and the lack of water channels and berts, stabilization devices such as mettresses, blar*ets, gabions, stones or concrete revetments wdl not be necessary if problems should arise details concoming these types of protocuon may be found in J. Trourbier and R. Westmecott (reference 11.11).

8.3 Time is necessary for vegetation to becomo established after seeding The winter ammaan is not I
conducive to germination. Mao, vegetation is difReult to ==*=huah in areas of concentrated surface runoff and high velocity To enhance germiruution, mulch wlN be appiled on any critical erosion sites (see Section 7.2 for quantiles of mulch). Seed mtxtures wel be chosen in accordance with standards consistent with sol drainage and area usage The time, rate and procedures for seeding wel be followed as recommended by the agricultural agent or per reference 11.10.
8.4 Seeding methods indude grain drtis, cultipackers, or conugeted rollers with grass seeding attachments; hand operated cyclone seeders; truck-enounted broadcast seeders; or hydroceeders.
However, because the site area is smed (approximately 1.1 acres), the probable method of seed
)i l
application wel be by hand, cyclone seeder or hg: 3g. The letter also allers the advantage of simultaneous apf*=tian of fertilzers and mulch. l 8.5 Permanent vegetation should include perennial grass or grass 4egume mixtures. Grasses, such as f Kentucky 31 Tall Fescue, Redtop Creepmg Red Fescue, Reed Canary grass, Perenruel Rye grass, Smooth Bromegrass, or Timothy and legumes, such as Crownvetch, Birdefoot Trefoi and #falla, may be used. Also, Crs.r.c2. is already established on a mejor portion of the Company property Lime and fortdizer may also be used if sol conditions are found to be poor.
