15e Cover of Disturbed Areas
Detail "A" below indicates the proposed placement of four (4') feet of
cover material over all areas which have been landfilled. Maximum
slopes will be limited to 3:1, and minimum slopes will be two (2%)
percent in landfilled areas.
In areas outside the limits of landfilling, a maximum of six (6")
inches of soil will be place. Maximum slopes will be limited to 2:1,
with minimum slopes of 1% maintained.
Cover soils will continue to come from the borrow area southeast of
the site.

PLACEMENT OF COVER SOIL
ORIGINAL(Red)
When Delta advises that the capping is complete, Meiser & Earl will
randomly dig auger holes to ascertain that the four (41) feet of soil
is placed, and will have soil samples from several of said auger holes
analyzed to check for conformance with 75.24 (c) (2) (ix). A soil
sample was tajcen from the borrow area on May 7, 1985 and analyzed for
grain size distribution. The sample was eleven (11$) percent coarse
fragments, forty-four (44%) percent sand, thirty-one (31%) percent
silt and fourteen (142) percent slay; resulting in a loam
classification.

15g Gas Venting
Delta has entered into a contract with American Gas Recovery
Corporation of Maple Shade, New Jersey whereby American Gas will
actively extract the landfill gas and convert it into salable energy.
American Gas applied for a permit in January of 1983 to install the
gas recovery wells at the referenced site, and was advised that the
permit could not be issued until the Consent Order had been executed.
American Gas is awaiting issuance of the permit fro the Department, in
order to install the vents.
In the event that American Gas abandons active gas extraction in the
future. Delta will utilize the gas wells as passive vents or if,
needed as active extraction wells.
During the construction'of the wells, Delta will make certain that
American Gas seals the well casing with bentonite or similar grout at
the surface to prevent rainwater and runoff from entering the refuse
mass around the casing.
SOIL EROSION AND SEDIMENTATION CONTROL PLAN
44.1 A general statement of the project must be included in the narrative.
44.11 General Description of Project
Delta Stotler Landfill is an existing landfill located in Antis and
Logan Townships in Huntingdon County, Pennsylvania. The project shall
consist of grading the existing landfill area and providing sufficient
soil cover and vegetation for final closure.
44.12 General Description of Storm Hater
The general concept of storm water management and soil erosion and
control is to divert and collect all water generated from the closure
areas. In order to accomplish this, storm water runoff will be
diverted via interceptor berms and rock lined ditches and directed to
sedimentation basins. The flow from the sediment basins will be
discharged via a riser inlet principal spillway and an emergency
spillway.
44.13 General Description of Soil and Erosion Control
Potential erosion areas will be stabilized concurrent with earth
moving activities. In that exposed areas are the largest sediment
source, efforts will be directed to limit any unnecessary exposure of
soil. Concurrent seed bed preparation, fertilizing, seeding, and
mulching will be used on non-active exposed areas. Eroded channels
flR200252
ORIGffeAl
will be regraded and/or lined with straw bales if they should form.
Permanent slopes will be stabilized by seeding and mulching immediately
following final construction. All grass diversions will be stabilized
following grading. Filter fence and/or straw bales will be located
along slopes to prevent soil laden runoff until such areas are
stabilized.
44-14 General Description of Sedimentation Control
The philosophy of sedimentation controls incorporated in this plan is
to route sediment laden water by the use of interceptor berms and rock
lined trenches to sedimentation basins. The sedimentation basins are
located in close proximity to high sediment source areas. The
discharge from these basins is routed to existing storm water
channels or converted to sheet flow.
Sediment control is also provided by water being detained behind
filter fabric fences and or straw bales which are proposed throughout
the active construction area. Additionally, rock gabions will be
provided in the rock lined channels which will act as small check
dams.
44*15 Date the Project is to Being and Expected Date the Project
Installation is to be Completed
The project has already commenced and project completion is subject to
weather conditions and time of year, but is expected to be completed
within one growing season following approval of the plan.
AR200253
44.16 Person Preparing the Plan
This plan was prepared by Richard M. Bodner, P.E. Mr. Bodner's
experience in^this field includes:
1. Design of numerous erosion and sedimentation control plans for
sanitary landfills, subdivisions, and similar earthmoving
projects.
2. Taught soil mechanics laboratory courses at Clarkson University.
3. Is a professional engineer registered in the Commonwealth of
Pennsylvania and several other states.
44.2 Topographic Features of the Project Site
44.21 The Location of the Project Relative to Highways,
Municipalities or Identifiable Landmarks
The site is located in Antis and Logan Townships in Huntingdon County,
Pennsylvania along the east side of the Tyrone River, south of
Altoona, Pennsylvania. A location map contained herein shows the
regional location.
ORIGWAf./Rfln)
44.22 Contours at an Interval that Would Adequately Describe
Topography
The site has been flown and a photogrammetric contour maps has been
prepared. These maps, at a scale of 1" = 200' with a 5' contour
interval, form the basis for the site design.
44,23 Boundary Lines of the Project Area———————————_—_——»—_—— f
The boundary lines of the project area are shown on the plan which
includes the approximate location of property lines and limits of the
closure area. - ——
44.24 Acreage of the Project
The area of the landfill proposed for closure is approximately 95
acres.
44.25 Streams, Lakes/Ponds or Other Bodies of Hater Within the
Project Area
There are several existing small ponds located on or along the project
site. Several of these areas are man-made ponds and will be utilized
for sedimentation control. The Little Juniata River is located to the
east of the project site. Additional features mentioned above are
shown on the location map contained herein.
5R2GQ255
44.26 Other Physical Features Including Scale Map'North Arrow
All maps have the appropriate scale and north arrow shown and also
show homes, barns, fence lines, trees, roadways and other physical
fea tures.
44.3 The Types, Depths, Slopes and Areal Extent of the Soils must be shown
on the map. The soils of the site as mapped by the soil conservation
district all Hagerstown very silty clay loam and Morrison very stoney
sandy loam. The site has been utilized as a Sanitary Landfill,
therefore, the current soil type consist of a mixture of refuse and
soil. The final cover to be provided will consist of four (41) feet
of the native soil.
44.4 Proposed Alterations
44.41 Changes to Land Surface and Vegetative Cover
The existing project is currently utilized as a sanitary landfill.
The project will consist of regrading the final surface of the
landfill providing a soil and vegetative cover. Final slopes shall
not exceed 3:1 slopes or be less than two (2%) percent slope.
44.42 Areas of Cuts and Fills
The 75 acres of landfill area will be regraded and filled to provide 4
feet of soil cover.
flR200256
44.43 Structures, Roads, Paved Areas and Buildings
The locations of all existing buildings, roadways and other structures
area shown on the existing topographic map. The project does not
propose any additional such facilities.
44,44 Storm Hater Facilities
The locations of all interceptor berms, rock lined channels and
sedimentation basins are shown on the soil erosion and sedimentation
control plan.
44.45 Contours of the Finished Areas
.The project proposes to provide a final soil cover which will be
placed approximately parallel to the existing topography. In that the
contour map provided has a 5' interval, and the soil cover provided
is 4 feet, the final contours have not been reflected on this
drawing.
44.5 The amount of runoff from the project area and the upstream water shed
area must be described in the narrative*
44.51, 44.52 Methods of Calculation and Factors Considered
Diversion berms and rock lined channel design. The _ rational method
for channel sizing was utilized for the design of the interceptor
berms and rock lined trenches. The following storm design basis were
flR200257
used for analysis. <'8rtu
Design Storm: 10 year storm
Runoff coefficient: 0,35 (assume final conditions to be meadow
like).
Sedimentation Basin Design The volume of the sediment basins are
based on 7000 cubic feet of storage per acre of drainage shed, with
approximately 5000 cubic being above the sediment clean-=out level.
The basin is provided with a barrel/riser type principal spillway.
The principal spillway was sized based on one of the following basis
which produced the least amount of discharge (so as not to increase
the amount of run-off leaving the site).
a. 2 cfs per acre.
b. 10 year post closure storm.
c. 10 year existing storm.
b and c above were calculated using the U.S.D.A., TR-55 - Urban
Hydrology for Small Water Shed Design Method. The emergency spillway
channel is provided for safe overflow of major storms.
44.53 Provisions for Safe Disposal
44.6 The staging of earthmoving activities must be described in the
narrative. This section is described as:
flR200258
Landfill closure procedure including land grading and establishment of
vegetation.
44.61 Cover and Removal and
44.62 Control Facility Installation and
44.63 Installation of Improvements
44,64 Schedule of Operations
Landfill closure procedures, land grading and establishment of
vegetation shall be implemented as follows:
1. Construct sedimentation basins and install filter fabric or straw
bales on downslope perimeter of basin.
2. Construct drainage shed perimeter interceptor berms.
3. Apply soil cover to landfill area, install interceptor berms and
rock lined channels as soil cover progresses.
4. Revegetate completed areas.
5. If necessary, install straw bales or filter fence in areas where
channels are eroded.
SR200259
44.7 Temporary control measures and facilities for use during earthmoving
must be shown on the map and described in.the narrative.
44.71 Purpose
As stated previously, the purpose of temporary control measures is to
reduce erosion while permanent vegetation is established. Also, straw
bales and filter fabric fences are used as temporary controls to
divert and detain runoff,, remove sediment through retention and
filtration, and reduce erosion by decreasing flow length. Straw mulch
will be used to temporarily stabilized areas.
44.72 Types of Measurers and Facilities
Straw bales and filter fabric will be installed to divert water, etc.
44.73 Locations of Measures and Facilities
Filter fabric and/or straw bales will be located along the sediment
basin outslopes during construction prior to establishment of
permanent vegetation. Also, straw mulch will be used on exposed areas
which are not actively being utilized for earth work. Since these
measures are continuously changing, they are not depicted on the
plans. Straw bales or filter fabric fence shall be utilized on eroded
areas of the final graded slopes.
AR200260
44.74 Dimensional Details of the Facility
Not applicable.
44,75 Design Consideration and Calculations
Mulch will be spread at 2-3 tons/acre. Netting will be used in
diversions as necessary to stabilize the mulch. Straw bales will be
stacked to prevent movement. Filter fabric fences will be constructed
as detailed on the plans.
44.8 Permanent control measures and facilities for site restoration and
long term protection must be shown on the map and described in the
narrative.
44,81 Purpose
The purpose of permanent control measures is to provide long term
protection to stabilize soil and intercept and detain runoff.
44.82 Types of Measures and Facilities
Permanent erosion and sediment control facilities incorporate an array
of methods which combine to perform as an integrated system. These
controls include:
1. Permanent grass cover on all areas of final cover and temporarily
disturbed areas;*
fiR20026!
2. Rock lined channels to direct site runoff on steep slopes to the
sediment basins;
3. Interceptor berrns constructed as grassed waterways to direct site
runoff to the sediment basins;
4. Five sediment basins; and
5. Hydraulic controls such as rock rip-rap and level spreaders
energy dissipation, principal and emergency spillways, rock rip-
rap channels.
44.83 Location of Measures and Facilities
All permanent controls are located as shown on the plans.
44.84 Dimensional Details of the Facilities
Construction details for all diversions are listed on the plans.
Values for sediment basins are located in the appendix. Dimensions of
other facilities such as pipes, principal spillways, etc. are listed
in the design section of the plan.
44.85 Design Construction and Calculations
All designs are based on the individual overall runoff, erosion and
sedimentation controls being integrated into a comprehensive system.
TR-55 or Chapter 102 was used to size and basins, whichever was more
conservative,
flR200262
Rock channels and interceptor berms were based on the rational method.
All design calculations and tables are contained in the appendix.
44.9 A maintenance program for the control facilities must be described
in the narrative.
44.91 The Method of disposal of Materials Removed from the Control
Facilities or the Project Area
Materials that are removed from the sediment basins will be used as
topsoil for seedbed preparation prior to establishment of permanent
vegetation. Other removed sediments will be spread and allowed to dry
prior to placement as soil cover. Thus, removed sediments will be
recycled to help alleviate erosion problems.
44.92 The Methods, Frequency and Ultimate Disposal Site for Solid
Material Must be Considered. The Facilities Must be Maintained
for their Designed Operation to Insure Adequate Performance.
All control structures (basins, diversions, etc.) will be inspected
the next working day after rainfall events in excess of one-half inch.
Also, a bi-weekly inspection will be conducted and sediment removed
according to the criteria established in this section. Diversions
will be reseeded, fertilized, etc. as necessary, to maintain the
needed performance level. Also, reseeding and fertilizing of
permanent vegetation will be completed to maintain effectiveness.
^200263
PERMANENT VEGETATION
Seed bed preparation shall be as follows:
A. Spread minimum of two (2) tons of agricultural limestone per acre (or
as may be required from soil tests). The lime shall be incorporated
by disking or cultipacking or both as may be necessary.
B. Basic fertilizer: 50-100-100 per acre (minimum).
C. Seed:
Slopes of 3:1 or less
Fescue, KY 31 tall 25 Ibs per acre
Winter Rye (if seeded in fall of year) 120 Ibs per acre
Birdsfoot Trefoil 5 Ibs per acre
Slopes steeper than 3:1
Fescue KY 31 tall 15 Ibs per acre
Winter Rye (if seeded in fall of year) 120 Ibs per acre
Crownvetch . 20 Ibs per acre
fj!.-:
Seed shall not be more than two (2) years old and shall have been
tested for germination not more than six (6) months prior to seeding
operations. Crownvetch shall be inoculated with approved culture as
recommended by the supplier.
In addition, willow trees will be planted initially in all low areas,
and ultimately may be planted across the site.
