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.
