1.0 INTRODUCTION
1.1 PURPOSE
This Borrow Area Use Plan (BAUP) has been prepared in accordance with the
requirements contained in Title 6 New York Code of Rules and Regulations (6 NYCRR)
Part 360-2.3(l). This BAUP is being submitted in support of a Solid Waste Management
Facility Permit Modification request for construction and operation of a soil borrow area
at the Chaffee facility, Town of Sardinia, Erie County, New York owned and operated by
Waste Management of New York, L.L.C. (WMNY). The sole purpose of the soil borrow
area is to provide soils for the construction and operation of the permitted landfill
operations at the Chaffee facility. The location of the Chaffee facility is shown on Figure 1.
The Chaffee facility property, south and north of Hand Road, consists of approximately 488
acres.
This BAUP and application package address proposed modifications to borrow activities
at the facility. The current soil borrow activities at the Chaffee facility are described in its
Mined Land Use Plan1 and current 6 NYCRR Part 360 (Part 360) landfill permit (9-1462-
00001/00006).
Appendix A of the BAUP includes a completed Part 360 Permit Application for this
modification request. The potential environmental impacts of the proposed soil borrow
operations are discussed in the Full Environmental Assessment Form (see Appendix B) and the
Environmental Assessment Report (see Appendix C).
1.2 SCOPE
This BAUP has been developed in accordance with the requirements of 6 NYCRR Part 422
and includes a Borrow Plan and the Reclamation Plan, each of which include a graphic
portion and a written portion.

2.0 BORROW PLAN
2.1 INTRODUCTION
This BAUP describes development and reclamation of a Proposed Borrow Area at the
WMNY Chaffee facility. Presently, the 6 NYCRR Part 360 Solid Waste Management Facility
Permit (Permit) for this facility provides for a 52.5 acre Western Landfill Expansion. The Final
Environmental Impact Statement2 (FEIS) indicated that a previous borrow area was withdrawn
during the expansion permitting process due to property zoning and that soil material required
for construction and operation would be imported. Development of the Proposed Borrow
Area, which is located in a properly zoned area, will reduce the amount of soil material to be
imported to construct and operate the Western Landfill Expansion.
As shown on Figure 2, the Proposed Borrow Area consists of an East Area and West Area,
totaling approximately 30.9 acres in size, to the south and southeast of the existing landfill.
WMNY is planning to operate the Proposed Borrow Area in two phases, the West Area will
be excavated first followed by the East Area. The West Area is approximately 16.1 acres and
the East Area is approximately 14.8 acres. Approximately 400,000 cubic yards and 600,000
cubic yards of material will be excavated from the West and East Areas respectively. WMNY
is proposing excavation of soils to a depth of up to approximately 50 feet below the existing
surface elevations.
This section describes the existing conditions, the borrow operations and a brief discussion of
the potential environmental impacts. The Proposed Borrow Area will be reclaimed to wetland
habitat, wildlife habitat and upland meadows, as discussed in Section 3.0.

2.2 EXISTING CONDITIONS
2.2.1 Borrow History and Land Use
The facility first obtained a mining permit in June of 1988. This permit addressed
excavating soil in the Clay Borrow Area, the Settling Basin Excavation Area, and the
Gravel Borrow Area. This permit was amended in August 1989 and renewed in May
1991, October 1994 and June 1999. The approximate limits of these borrow areas are
shown on Figure 2. The status of these borrow areas are summarized below:
• “Clay Borrow Area” (17.7 acres) – Located to the west of the existing landfill.
Borrow activities have been completed and the area is now part of the Western
Landfill Expansion footprint;
• “Settling Basin Excavation Area” (4 acres) – Located south of the Clay Borrow
Area. Borrow activities have been completed and the settling basins are
constructed; and
• “Gravel Borrow Area” (7.2 acres) – Located in the southern portion of the site.
Borrow activities partially completed but continue under the current mining
permit.
WMNY maintains a current mining permit to cover operations at the Gravel Borrow Area
(NYS Mining Permit No. 9-02803, MLR File 9043-30-0216).
The current Permit (9-1462-00001/00006) addresses excavation of soil materials from two
areas denoted as Clay Borrow Area A and Clay Borrow Area B. Each of these areas is
also shown on Figure 2. The status of these borrow areas are summarized below:
• “Clay Borrow Area A” (10.6 acres) – Located south of the Clay Borrow Area.
Borrow activities have been completed and the area is now part of the Western
Landfill Expansion footprint; and
• “Clay Borrow Area B” (17.5 acres) – Located in the southwest corner of the
property. Borrow activities have been completed and the area has been reclaimed.

Most of the Town of Sardinia, including the Chaffee facility property, lies within Erie
County Agricultural District #6. Economic activities near the Proposed Borrow Area are
primarily agricultural. Except for the landfill operation, the properties surrounding the
Proposed Borrow Area are wooded, farmland, and residential. The farming activity
consists primarily of dairy farming, with hay, pasture, and corn the most common
agricultural land uses. The Chaffee facility property is currently not used as active
farmland or part of an active agricultural operation. Prior agricultural uses of the property
included pasture and hay land.
The Chaffee facility property has two major land use categories at this time, wildlife
habitat and municipal solid waste landfilling. Landfill operations include the 50.93 acre
Existing Landfill, the 52.5 acre Western Landfill Expansion and approximately 160 acres
of ancillary facilities on the site, including leachate storage tanks, sediment ponds,
office/maintenance buildings, access roads, etc., as shown on Figure 2.
2.2.2 Existing Topography
The Proposed Borrow Area lies within the headwaters of Hosmer Brook, which is part of the
Cattaraugus Creek drainage basin. This area is part of the south slope of the Lake Escarpment
Moraine, with general southward slopes of approximately one percent.
The eastern portion of the Proposed Borrow Area (East Area) can be described as an
elongated ridge that is oriented north to south. This area has elevations ranging from 1500 feet
in the central portion to 1455 feet toward both the southeast and southwest.
The western portion of the Proposed Borrow Area (West Area) is a conical ridge. This area
has elevations ranging from 1490 feet in the north central portion to 1450 feet toward both the
southeast and southwest.

Waste Management of New York 2-4 G:\Projects\Chaffee\Borrow Pit Permit 2008\Borrow Area Use Plan.doc
2.2.3 Soils
Subsurface conditions at the site have been investigated as part of the landfill operations
over approximately the past 30 years by drilling test borings and through observations
made during borrow operations. The data available from these test borings were
supplemented with four additional test borings and three additional monitoring wells
within the Proposed Borrow Area limits (see Figure 2). Two cross sections illustrating the
soil conditions observed at the boring locations are included on Figure 3. Test boring logs
are included in Appendix D.
In general, soils at the site occur as a result of glacial deposition at the Lake Escarpment
Moraine. The test borings indicate that the soils consist of a topsoil layer overlying a clay
till deposit, followed by an underlying formation of coarse sand and gravel. These soil
deposits do not vary significantly from those discussed in the Hydrogeologic Report for
the proposed Chaffee Western Landfill Expansion3. The clay till is a brown silty clay that
has interbedded seams of sand and sandy gravel. The clay till is between 20 and 40 feet
thick, and was observed at an approximately elevation (El.) 1438 feet in SB3-08 and at an
approximate El. 1451 feet in SB1-08. As noted in the Hydrogeologic Report, the
underlying formation of coarse sand and gravel has been estimated to depths of 400 feet,
extending down to bedrock.
The interbedded seams of sand and sandy gravel were demonstrated to be laterally
discontinuous as noted in the Hydrogeologic Report. Comparison of the interbeds in
several borings and wells indicates that they are not continuous. Hydraulic conductivity
tests performed in clay till wells within interbeds indicate that the interbeds are
discontinuous.

BAUP Chaffee Facility File: 00-016
Waste Management of New York 2-5 G:\Projects\Chaffee\Borrow Pit Permit 2008\Borrow Area Use Plan.doc
2.2.4 Groundwater
Two zones of groundwater are present within the Proposed Borrow Area; 1.) the clay till
exhibits a perched water table with a vertical hydraulic gradient; and 2.) the underlying
formation of coarse sand and gravel contains the water table with a horizontal gradient. As
noted in the Hydrogeologic Report, the water table in the clay till confining unit is not
directly hydraulically connected to the underlying formation of coarse sand and gravel.
The water table in the underlying formation of coarse sand and gravel exhibits flow
patterns to both the north and south.
Three groundwater monitoring wells were installed as part of this project. SB6-08 is
screened in the clay till and appears to intercept a sand interbed. The February 2009
groundwater elevation in this well is 1465.29 feet. SB4-08 and SB9-08 are both screened
in the underlying formation of coarse sand and gravel. The February 2009 groundwater
elevations are 1440.08 feet and 1437.90 feet respectively. The groundwater levels in the
underlying formation of coarse sand and gravel appear to correlate with those measured
and recorded as part of the Hydrogeologic Report.
It is improbable that wetlands at the site are recharged by groundwater that is perched
within the clay till formation. The low hydraulic conductivity of the clay till formation
suggests that groundwater flow alone is not capable of sustaining elevated water levels in
the wetlands. Furthermore, because a continuous bed of more permeable material was not
observed in the test borings, a groundwater flow path was not defined.
2.2.5 Surface Water Drainage Earth Dimensions, Inc.4 (EDI) delineated wetlands located within and adjacent to the
Proposed Borrow Area (see Figures 2 and 3). As indicated on the figures, two wetlands,
identified as SD-1 and AR-11, are NYSDEC jurisdictional wetlands. EDI identified the
remaining four wetlands, identified as W1A, W3, W4 and W6 as potential USACE
jurisdictional wetlands. The wetland boundaries have been submitted to the NYSDEC and
BAUP Chaffee Facility File: 00-016
Waste Management of New York 2-6 G:\Projects\Chaffee\Borrow Pit Permit 2008\Borrow Area Use Plan.doc
USACE for review. EDI has indicated that wetlands designated W3, W4 and W6 may be
non-jurisdictional, which means that the wetlands can be removed without providing
wetland mitigation for these areas. If the USACE finds that any of these wetlands are
jurisdictional, WMNY will submit a plan and permit application for mitigation of the
affected wetlands.
Surface water from the Proposed Borrow Area flows from the north to the south. Surface
water from the north side of the main access road flows into wetlands SD-1 and AR-11
through culverts beneath the road. Surface water is also directed toward the wetlands from
roadside drainage channels along the south side of the main access road. Overland flow
emanating from topographically higher terrain within the proposed borrow areas flows at the
surface of the low permeability clay till formation and provides further recharge to each
wetland. Both wetlands discharge to the south of the site and contribute to Hosmer Brook, a
Class C(T) stream.
The potentially jurisdictional wetland W1A and non-jurisdictional wetlands W3, W4 and W6
within the Proposed Borrow Area occur in aerially small isolated depressions within the well-
vegetated upland area and are recharged by overland surface water flow.
Approximately one-half of the surface water runoff from the West Area flows into the
existing sedimentation basins and the other half flows into NYSDEC jurisdictional wetland
SD-1. As indicated on Figure 2, water flowing toward or into the existing sedimentation
basins will eventually enter SD-1. Approximately two thirds of the surface water from the
East Area flows into SD-1 while the remaining one third flows into NYSDEC
jurisdictional wetland AR-11.
The wetlands are composed of forested swamps, shrub wetlands, and emergent marshes
with very little open water. SD-1 meets the criteria for New York State Wetland Class II,
and is a significant wildlife habitat because of its heterogeneous cover types in the adjacent
upland.

2.2.6 Man Made Features
The Proposed Borrow Area lies on the south side of the existing landfill and main access
road. The area is forested and does not currently contain man made structures or features.
2.3 DESCRIPTION OF MINERAL AND BORROW OPERATIONS Excavation in the Proposed Borrow Area will consist of removing a majority of the clay
till deposit. In general, 2 to 4 feet of clay till will remain in the areas, therefore no borrow
activities will occur within the underlying formation of coarse sand and gravel.
2.3.1 Mineral Types
As discussed in Section 2.2.3, the borrow operation will be in the deposit of clay till. The
clay till material will be used for landfill construction and operations.
2.3.2 Borrow Sequence and Method
The Proposed Borrow Area includes two areas as described above. The West Area is
approximately 16.1 acres in area, and will be excavated from east to west between El.
1450 feet to El. 1440 feet. The East Area is approximately 14.8 acres in area, and will be
excavated from east to west between El. 1455 feet to El. 1445 feet. WMNY is planning to
operate the Proposed Borrow Area in two phases, the West Area will be excavated first
followed by the East Area.
Excavation in each area will start at the lowest elevation by first creating a sedimentation
basin that complies with the New York State Standards for Erosion and Sediment
Control. These basins will be constructed with outlet devices and will be vegetated prior
to continuing the borrow area excavation (see Figures 5 through 7). The West Area Basin
should be developed approximately three months prior to beginning the borrow area
operation. The East Area Basin will be developed one year prior to completion of the
West Area, this will allow for the basin to be well established before borrow area
operation. Each area will then be excavated following the proposed floor slope.
BAUP Chaffee Facility File: 00-016
Waste Management of New York 2-8 G:\Projects\Chaffee\Borrow Pit Permit 2008\Borrow Area Use Plan.doc
Excavations will be developed and maintained so that runoff from disturbed areas flows
through drainage swales and silt traps into the constructed basins. Upon completion, the
Proposed Borrow Area will contain permanent basins and gentle to steep sloping upland
areas.
As shown in the cross-sections on Figure 4, the Proposed Borrow Area is designed to
maintain the excavation within the clay till deposit. The base grades were developed using
the bottom of clay till observed in the test borings. If the bottom of the clay till is
encountered during excavation, the base grades will be either revised to maintain at least 2
feet of clay till above the underlying formation of coarse sand and gravel or over
excavations will be replaced with a minimum of 2 feet of compacted clay till.
The work sequence at the Proposed Borrow Area is described below.
1. The West Area will be excavated first, beginning with the sedimentation basin.
2. Silt fence or other temporary erosion and sediment control structures will be
placed along the boundary between the proposed borrow area and the NYSDEC
wetlands to prevent sediment discharge.
3. Clear, grub and strip topsoil from the sedimentation basin area and haulageway and
store the material for future reclamation (stockpiles will be treated as described in
Section 2.3.6).
4. Grade the haulageway to direct surface water runoff to the existing and proposed
sedimentation basins.
5. Excavate material to construct the sedimentation basin and transport it to the work
area at the landfill.
6. When construction of the sedimentation basin is complete, clear, grub and strip
topsoil from the borrow area as required for each year’s construction/operation.
7. Maintain drainage swales and silt traps to direct surface water from the current
excavation area to the sedimentation basin.
8. Excavate slopes to the required reclamation grades so that backfill is not required
at a later time.
BAUP Chaffee Facility File: 00-016
Waste Management of New York 2-9 G:\Projects\Chaffee\Borrow Pit Permit 2008\Borrow Area Use Plan.doc
9. Apply temporary seeding and mulch to completed areas to create a buffer between
the excavation area and sedimentation basin. Reclamation will not occur until the
entire area is excavated and graded.
10. The East Area will be excavated upon completion of the West Area. The sequence
of work will follow the same steps as described above.
Excavation within the proposed borrow area, as shown on the figures, will not remove any
portion of the NYSDEC jurisdictional wetlands, USACE jurisdictional wetland W1A or
any associated buffers. In addition, no vegetation removal, equipment access, or other
disturbances to these regulated wetlands and buffers will occur during borrow activities.
Additionally, silt fences, stormwater basins and other erosion and sediment control
measures will be utilized to protect the wetlands during soil borrow operations.
Potentially non-jurisdictional wetlands W-3 and W-4 in the East Area and W-6 in the West
Area will be removed during operations in the Proposed Borrow Area. If the USACE finds
that any of these wetlands are jurisdictional, WMNY will submit a plan and permit
application for mitigation of the affected wetlands.
An inoperable natural gas well may be present in the Proposed Borrow Area. The gas well was
not encountered during development of this BAUP, however, if it is encountered during the
proposed borrow operations, excavation activities will be suspended in the immediate area and
the NYSDEC will be notified. WMNY will then proceed with decommissioning the well as
directed by the NYSDEC.
The three monitoring wells that were installed during development of this BAUP will be
decommissioned as they are encountered during excavation.
2.3.3 Grading and Setbacks
The grading plan for the Proposed Borrow Area is depicted in plan view on the
Reclamation Plan, and on the cross sections shown on Figure 4. Grading and borrow area
perimeter setbacks will be as follows.
BAUP Chaffee Facility File: 00-016
Waste Management of New York 2-10 G:\Projects\Chaffee\Borrow Pit Permit 2008\Borrow Area Use Plan.doc
• The perimeter slope of the basins from water's edge to undisturbed adjacent land
will be on a slope no greater than 1 vertical on 3 horizontal;
• A set back of 25 feet from the top of slope of the borrow area to the property lines
will be maintained; and
• A 100 foot buffer will be maintained on areas bordering the NYSDEC designated
wetlands. The wetland buffer will be demarcated with temporary construction
fencing that will be maintained throughout the life of borrow activities.
Care will be taken during excavation operations to prevent the need for backfilling slopes
at a later time. Excavations shall be made to the reclamation grades shown on Figure 4.
2.3.4 Processing Material processing will not occur as part of this project.
2.3.5 Haulageways and Site Access Haulageways will be used for employee access, equipment access, and for transporting soil
material. The haulageways will be graded, stabilized, and maintained as necessary to
provide safe, efficient operations and to minimize erosion and off-site sedimentation.
2.3.6 Storage of Materials and Disposal of Wastes
Topsoil from the Proposed Borrow Area will be stockpiled at the facility. Temporary
erosion and sediment controls will be placed around the topsoil pile. The topsoil pile will
be seeded as described in Section 2.4.4. Brush will be stored temporarily within each area.
Prior to accessing the material beneath the pile, the brush will be chipped for placement
either on temporary roads in the Proposed Borrow Area or in operation of the landfill.
BAUP Chaffee Facility File: 00-016
Waste Management of New York 2-11 G:\Projects\Chaffee\Borrow Pit Permit 2008\Borrow Area Use Plan.doc
Topsoil will be stripped from portions of the borrow areas as they are developed. The
topsoil from each area will be placed in the stockpile. A silt fence will be placed
downgradient of the topsoil stockpile. Material will be added to the stockpile as additional
portions of the borrow areas are developed. Therefore, the topsoil stockpiles will have a
working face where additional material will be placed in the future.
Seeding will be placed on areas of the stockpile that will not receive additional material.
The stockpiles will be seeded within 30 days of material placement. Additionally, seeding
will be placed on the working face of stockpiles that are not planned to receive additional
material within the remainder of the current construction season.
The following seed mixture will be used as temporary revegetation on stockpiles.
Common white clover 8 lbs/acre
Tall fescue 20 lbs/acre
Perennial Ryegrass 10 lbs/acre
Any non-hazardous solid waste that is produced during Proposed Borrow Area operations will
be disposed of at the landfill.
2.4 POTENTIAL ENVIRONMENTAL IMPACTS
A complete discussion of the potential environmental impacts due to the creation of the
Proposed Borrow Area is included in Appendix C, the Environmental Assessment Report. A
brief discussion of air, noise and water pollution is included below.
2.4.1 Control of Air Emissions
As needed, roads, loading areas, and working faces will be sprayed with water to minimize
airborne dust.
2.4.2 Control of Noise
BAUP Chaffee Facility File: 00-016
Waste Management of New York 2-12 G:\Projects\Chaffee\Borrow Pit Permit 2008\Borrow Area Use Plan.doc
The same equipment that is involved in the current borrow operations and on the adjacent
landfill, where it meets the Part 360 noise regulations, will continue to be used at the
facility. The potential changes in noise levels will be due to the operation of excavation
equipment at locations adjacent to facility property lines. Based on an estimate included in
Appendix C, sound level increases at the closest receptors would be considered unnoticed to
tolerable.
2.4.3 Control of Water Quality and Quantity
Surface water will be controlled within the Proposed Borrow Area as described in Section
2.3.2. The erosion and sediment control systems were developed in accordance with the
New York State Stormwater Management Design Manual (NYSDEC, October 2001).
The New York State Stormwater Management Design Manual contains guidance on the
sizing of sedimentation control basins. Additionally, the facility maintains a Stormwater
Pollution Prevention Plan (SWPPP) and Spill Prevention Control and Countermeasure
Plan (SPCC), these documents provide details for training, record keeping, potential
sources of pollution, best management practices and cleanup procedures.
2.4.4 Silt Control
As described above, both the West and East Areas will contain sedimentation basins
consisting of a forebay and permanent pool. These sedimentation basins will be used to
remove sediments from water that collects as the remaining portion of the borrow area is
developed. Water will flow by gravity into the forebay and then into the permanent pool
for eventual discharge into the NYSDEC regulated wetland. Accumulated sediments will
be removed when 50 percent of the forebay storage capacity is filled.
Surface water runoff from the Proposed Borrow Area will be contained within the
excavation area. Temporary erosion and sediment control structures will be placed
between the excavation areas and the demarcated wetlands.
BAUP Chaffee Facility File: 00-016
Waste Management of New York 2-13 G:\Projects\Chaffee\Borrow Pit Permit 2008\Borrow Area Use Plan.doc
Drainage along the main access road will continue to convey stormwater to the designated
outflow points. If drainage patterns are altered as a result of excavation activities, all flow
will be directed into the borrow area and subsequently into the sedimentation basins.
Temporary stockpiles will be graded, stabilized, and maintained as necessary to minimize
sediment transport. A silt fence will be placed downgradient of stockpiles. Stockpiles will
be seeded within 30 days of material placement.
Erosion and sediment control measures will be inspected periodically and repaired as
necessary, as indicated in the SWPPP.
2.4.5 Water Table
The Proposed Borrow Area is separated into a West and East Area; each area will be
graded to drain to a sedimentation basin. The deepest portion of each area will be within
the sedimentation basin; neither is expected to penetrate the underlying formation of sand
and gravel.
Monitoring wells SB4-08 and SB9-08 are screened in the underlying formation of coarse
sand and gravel. These wells indicate that the water table is several feet below the top of
the coarse sand and gravel formation. The borrow operation will be in the clay till deposit
above the underlying formation of coarse sand and gravel, therefore the excavation will
occur above the water table.
Monitoring well SB6-08 is screened in the clay till formation and groundwater has been
observed in this well. Based on the discussion in Section 2.2.4, this groundwater is likely
representative of a perched groundwater table and may fluctuate seasonally. During
excavation of the clay till deposit, groundwater may be present in isolated areas and during
the wet seasons of the year. In general, this groundwater will not generate large flows and
can be directed to the sedimentation basins.

3.0 RECLAMATION PLAN
Proposed reclamation plans for the areas of the Chaffee facility that were previously permitted
are not modified by this application. These areas have been reclaimed as described in their
respective Mined Land Use Plans. The following sections discuss the reclamation of the
Proposed Borrow Area.
3.1 LAND USE OBJECTIVE
The land use objective for the Proposed Borrow Area will be two permanent basins for
wetland habitat, wildlife habitat, and upland meadows. The final base grades and basins are
shown on Figures 4 through 7.
3.1.1 Disposition of Materials Material borrowed from the site will be used for landfill construction and operations on a
daily basis with little stockpiling, residue, or refuse. Topsoil will be replaced to a depth of
4 to 6 inches on all areas of the excavation. Prior to topsoil placement, all areas should be
scarified.
Oversized material, if encountered, will be buried to a compacted depth no less than 2
feet. Some boulders may be placed on the floor of the permanent pool to serve as habitat.
Any brush that remains will be chipped and used during reclamation or in the operation of
the landfill. The Proposed Borrow Area will contain no permanent equipment or refuse
and will be operated in a clean and orderly fashion on a daily basis.
Spoil and unused aggregate will be placed against the borrow area face or will be used to
create irregular topography during reclamation. Spoil piles will not remain on the site after
borrow operations are terminated.

3.1.2 Haulageways & Access Locations
Access roads or haulageways will be constructed from the main site access road into each
area. Temporary haul roads within each area will be constructed as necessary to allow for
the excavation to proceed. The temporary haul roads will be removed during reclamation,
the main haulageways will remain for site access to the newly formed basins. Gravel will
be placed on the access road surfaces to aid in erosion control and provide a stable
surface.
3.1.3 Drainage and Grading
The side slopes of the proposed borrow area will be graded to a maximum slope of 3
horizontal on 1 vertical. The slopes will be created by excavating to the lines and grades
indicated on Figure 4.
Two basins will be created as a result of operations within the Proposed Borrow Area.
Drainage patterns outside the footprint of the Proposed Borrow Area will not be altered and
the Proposed Borrow Area floor in each area will be graded to drain into the created basins.
Both basins will discharge into NYSDEC wetland SD-1, therefore all areas will continue to
contribute to Hosmer Brook.
Discharge during operations from both basins will be through the drainage pipes and surface
spillways. During reclamation, the drainage pipe will be decommissioned, which will allow
each basin area to form into permanent ponds with outflow through the surface spillways at an
elevation of approximately 1446 feet for the West Area and approximately 1451 feet for the
East Area. The spillways, in conjunction with basin grades, will create deep water and aquatic
shelf habitat within the basins. The spillways will be graded and stabilized as indicated on
Figures 5 through 7.

Waste Management of New York 3-3 G:\Projects\Chaffee\Borrow Pit Permit 2008\Borrow Area Use Plan.doc
3.1.4 Re-vegetation
Topsoil will be placed on the reclaimed ground surface and slopes above the basin level as
shown on Figures 4 through 7. The topsoil will be seeded using the following mixture.
Common white clover 8 lbs/acre
Tall fescue 20 lbs/acre
Perennial Ryegrass 10 lbs/acre
Re-vegetation will restore the shores of the basins to a natural state. With prolonged
exposure to saturation and inundation, the soils that are placed in and around the basins
will become hydric in nature, which will promote the expansion of hydrophytic vegetation
from the existing wetland into the newly created basin.
Woody species plantings will be made in the meadow portion of the borrow area and will
include some species that would occur naturally in unplanted farm fields and others that
are considered to provide good elements of wildlife habitat. Species such as Aspen, Pine,
Hawthorn, and Wild Pear will be planted in arbitrary locations, in clumps, and in rows.
Natural succession of vegetation will follow. The reclaimed area will result in a diversity
of upland and wetland cover types.
Additional tree plantings will occur along the southern boundaries of each borrow area.
Native species of trees will be planted along these boundaries both within the 25 foot
setback area and within the first 25 foot area of each borrow area. This will create a 50
foot wide forested strip along the property line upon completing the reclamation.
Animal species will not be introduced to the site, however a natural progression of animal
habitation will occur due to the plant selections, the hydrogeology, the terrain/topography,
and the proximity of the site to NYSDEC jurisdictional wetlands SD-1 and AR-11.

Waste Management of New York 3-4 G:\Projects\Chaffee\Borrow Pit Permit 2008\Borrow Area Use Plan.doc
3.1.5 Wetland Mitigation
No work will occur in the jurisdictional wetlands or buffer zones. As such, wetland
mitigation is not required.
3.2 RECLAMATION SCHEDULE
The Proposed Borrow Area is separated into two areas, West and East. The West Area
will be excavated first, starting from the southeast and working toward the northwest. The
East Area Basin will be excavated one year prior to completion of the West Area. Borrow
operations in the East Area will commence upon completion of the West Area and will be
excavated starting in the southwest corner and working toward the northeast. Temporary
grading and seeding will occur after each construction season and final reclamation will
occur within one year after completing each excavation area.
All equipment and stockpiles will be removed from the site as part of reclamation.

1.0 INTRODUCTION
1.1 OBJECTIVE
This report provides an assessment of the potential environmental impacts associated with
development of a Proposed Borrow Area at the Waste Management of New York, L.L.C.
(WMNY) Chaffee facility. Presently, the 6 NYCRR Part 360 Solid Waste Management Facility
Permit (Permit) for this facility provides for a 52.5 acre Western Landfill Expansion. This landfill
expansion will require large quantities of soil for liner and cap construction. This report has been
prepared to support a proposed modification to the Permit to allow for development of a Proposed
Borrow Area consisting of an East Area and West Area, totaling approximately 30.9 acres in size,
to the south and southeast of the existing landfill. Figure 2 in the Borrow Area Use Plan (BAUP)
shows the locations and lateral extents of the Proposed Borrow Area. WMNY (the
owner/operator of the Chaffee facility) is proposing excavation of soils to a depth of up to
approximately 50 feet below the existing surface elevations.
Discussion and justification for the requested Permit modification is provided in Section 3, below.
No other changes to the design or operation of the facility are proposed for this modification
request.
1.2 REASON FOR PROPOSED MODIFICATION
The primary reason for the requested modification to the Permit is to provide an on-site source of
soil for construction of the landfill expansion liner system. Without this modification, off-site soils
will need to be obtained and trucked to the site for construction purposes.
1.3 SCOPE
The proposed development of the 14.8-acre East Area and 16.1-acre West Area borrow areas, has
the potential to impact the environment by:
• causing noise impacts at nearby receptor locations;
• eliminating some upland forest habitat;
Soil Borrow Area–Environmental Assessment Report Chaffee Facility File: 00-016
Waste Management of New York Page 1-2 G:\Projects\Chaffee\Borrow Pit Permit 2008\ChaffeeEnvAssessMining.doc
• reducing the visual screening of the landfill operations and
construction;
• causing some localized dust and vehicle emissions; and
• altering surface water runoff flow patterns and surface water quality
due to potential sediment transport.
All of these potential impact areas have been addressed in the Draft Environmental Impact
Statement (DEIS) for the proposed Chaffee Western Landfill Expansion (Reference 1). To the
extent that the impact evaluations included in the DEIS also apply to the Proposed Borrow
Area, they will be referenced in the discussions included in Section 3.
Soil Borrow Area–Environmental Assessment Report Chaffee Facility File: 00-016
Waste Management of New York Page 2-1 G:\Projects\Chaffee\Borrow Pit Permit 2008\ChaffeeEnvAssessMining.doc
2.0 PROJECT DESCRIPTION
2.1 EXISTING LANDFILL
The Chaffee facility has 103.4 acres of permitted landfill cell area, with an approved design capacity
of 150,000 tons per quarter. Landfill cells are being constructed in accordance with the 6 NYCRR
Part 360 requirements. There will also be approximately 160 acres of ancillary facilities on the site,
including leachate storage tanks, sediment ponds, office/maintenance buildings, access roads, etc,
once construction of the Western Landfill Expansion is complete.
The facility is on Route 16, approximately 1 mile north of the Hamlet of Chaffee, in the Town of
Sardinia.
2.2 PROPOSED MODIFICATION - SOIL BORROW AREAS
WMNY is proposing to develop a Proposed Borrow Area (see Figure 2 in the BAUP) located to
the south and southeast of the existing landfill cell area. The soil borrow areas are approximately
16.1 acres to the west of New York State Department of Environmental Conservation (NYSDEC)
Wetland SD-1, and approximately 14.8 acres to the east of the wetland. A total of approximately 1
million cubic yards of material will be excavated. The majority of soil from this Proposed Borrow
Area will be used for landfill construction with a lesser amount used for daily and intermediate
cover. The soil borrow operations are described in the BAUP.
Soil Borrow Area–Environmental Assessment Report Chaffee Facility File: 00-016
Waste Management of New York Page 3-1 G:\Projects\Chaffee\Borrow Pit Permit 2008\ChaffeeEnvAssessMining.doc
3.0 POTENTIAL ENVIRONMENTAL IMPACTS
The discussion of potential environmental impacts in this section follows the general sequence and
approach used in the Full Environmental Assessment Form (FEAF) found in 6 NYCRR Part 617.
That document is used by NYSDEC to determine if an action may have a significant effect on the
environment. Although each of the impact areas included in the FEAF are considered in the
following sections, the specific impact areas listed in Section 1.3 (above) will be evaluated in more
detail, because they have been identified as the areas most likely to be adversely affected by the
proposed modification.
3.1 ZONING AND LAND USE
The Town of Sardinia has zoned the existing landfill site (including the proposed soil borrow area)
Business – Light Industrial. WMNY will work with the Town to obtain a Special Use Permit, in
order to proceed with development of the Proposed Borrow Area.
With the exception of the landfill itself, most of the land area within one mile of the Proposed Borrow Area is agricultural land, forested, or wetland.
3.2 WATER RESOURCES
Surface water flow patterns will be impacted by the development of the Proposed Borrow Area. As areas are cleared and excavated, storm water runoff will collect in the excavated areas. Excavation will begin in the southeast portion of the West Area, and the southwest
portion of the East Area. Sedimentation basins will be constructed in these two areas to collect and treat storm water before it is released to NYSDEC Wetland SD-1.
Storm water control facilities and procedures, as described in the facility’s “Stormwater Pollution Prevention Plan for Stormwater Discharges Associated with Industrial Activities, August 2007” (Reference 2), will be implemented in and around the soil borrow areas to control the quality and quantity of storm water discharges.
Soil Borrow Area–Environmental Assessment Report Chaffee Facility File: 00-016
Waste Management of New York Page 3-2 G:\Projects\Chaffee\Borrow Pit Permit 2008\ChaffeeEnvAssessMining.doc
Quantities of fuels and lubricants in the borrow area will be limited to the amounts contained in the mobile equipment, and the existing “Spill Prevention Control & Countermeasures Plan” will still be effective in reducing the risk associated with release of these materials. Two zones of groundwater are present within the Proposed Borrow Area, the clay till exhibits a perched water table and the underlying formation of coarse sand and gravel contain the permanent water table. The Proposed Borrow Area excavations are not planned to penetrate the underlying formation of sand and gravel, therefore no impact on the sand and gravel groundwater quantity or quality is expected. During excavation of the clay till deposit, groundwater may be present in certain areas and during the wet seasons of the year. In general this groundwater will not generate large flows and can be directed to the sedimentation basins for discharge. Implementation of these facilities and procedures will prevent significant adverse impacts to water resources due to the development of the Proposed Borrow Area.
3.3 AIR RESOURCES
Development of the Proposed Borrow Area could result in dust generation by excavation
activities and soil transport vehicles. These excavation and material transport activities would
not be materially different from those currently occurring at the facility, and similar mitigation
methods will be used to control impacts, as described below:
• Stockpiles of topsoil and subsoil expected to be in place for more than 30 days will
be vegetated or otherwise stabilized to control dust generation;
• Temporary re-vegetation of borrow areas will be completed after each construction
season upon reaching final grades;
• Entrances to the borrow areas will be stabilized to limit the amount of silt and mud
leaving the area on the tires of trucks and equipment;
• On-site unpaved roadways connecting the borrow areas to the cell construction
areas will be constructed of gravel, reducing the amount of fines potentially
Soil Borrow Area–Environmental Assessment Report Chaffee Facility File: 00-016
Waste Management of New York Page 3-3 G:\Projects\Chaffee\Borrow Pit Permit 2008\ChaffeeEnvAssessMining.doc
disturbed by truck traffic, and these roadways will be watered during dry weather
periods; and
• The nearest residential dwellings are along Route 16, either near the intersection of
Hand Road and Route 16 or adjacent to the Chaffee facilities main entrance,
approximately 2400 feet from the East Area. This buffer distance will reduce
potential dust impacts on sensitive receptors.
The second potential air resource impact is related to exhaust fumes generated by the trucks and
excavation equipment. Although these impacts will occur, trucking soils from off-site locations
would result in more truck emissions due to the longer haul distance, and excavation of soils would
be required at any borrow location. The fact that this facility has considerable buffer distances
between the soil borrow areas and off-site sensitive receptors (at least 2400 feet in all directions)
will mitigate potential air quality impacts due to vehicle exhaust.
The Chaffee facility is required to comply with applicable landfill air emissions permitting
requirements established by NYSDEC.
Air resources on and in the vicinity of the Chaffee facility will therefore not be significantly affected by development of the Proposed Borrow Area.
3.4 ECOLOGICAL RESOURCES
Evaluations of terrestrial and wetlands ecology were prepared as part of the DEIS (Reference
1), which confirmed the lack of significant impacts from the Western Landfill Expansion, and
the absence of threatened or endangered species on the Chaffee facility site.
Some woodland habitat will be lost either permanently or temporarily in the Proposed Borrow
Area, but this type of habitat is abundant in the region, and the borrow areas will eventually be
reclaimed as described in the BAUP. Nearby protected wetland areas (NYSDEC Wetland
SD-1 and AR-11) have been specifically avoided in the layout of the soil borrow areas.
Additionally a 100-foot buffer will be maintained around each NYSDEC wetland to protect
the ecological environment of the area.
Soil Borrow Area–Environmental Assessment Report Chaffee Facility File: 00-016
Waste Management of New York Page 3-4 G:\Projects\Chaffee\Borrow Pit Permit 2008\ChaffeeEnvAssessMining.doc
Ecological resources on and in the vicinity of the Chaffee facility would therefore not be
significantly affected by development of the Proposed Borrow Area.
3.5 AGRICULTURAL LAND RESOURCES
The area of the Proposed Borrow Area is within Erie County Agricultural District #6, but none of
the property owned by WMNY at this location is active farmland or part of an active agricultural
operation. Obtaining a special use permit for the Proposed Borrow Area will require notification of
active farms within 500 feet of the operation.
3.6 AESTHETIC RESOURCES
A “Visual Impact Analysis” was prepared as part of the DEIS (Reference 1). This study
determined that the view of the Chaffee Landfill is most significant in an area around the
landfill bounded by Hand Road to the north, Savage Road to the west, Allen Road to the
south and Route 16 to the east. Within this area there is some screening of the lower portions
of the landfill at viewpoints to the south and southeast by trees growing in the Proposed
Borrow Area. Removal of these trees will reduce the lower level screening, but the upper
portions of the landfill (which are 150 feet or more above the existing ground surface
elevations in the soil borrow areas) would be visible regardless of the existence of the trees.
Although lower level screening will be reduced, the incremental increase in visual impact
should not be severe.
3.7 HISTORIC AND ARCHEOLOGICAL RESOURCES
As indicated in the DEIS, the Chaffee facility site is not within an archeologically sensitive area,
based on New York State Historic Preservation Act records. An archeological site (UB Site
#1231) is located about 1 mile southeast of the Proposed Borrow Area. The presence of artifacts
at the site has not been verified, based on discussions with the University at Buffalo Archeological
Soil Borrow Area–Environmental Assessment Report Chaffee Facility File: 00-016
Waste Management of New York Page 3-5 G:\Projects\Chaffee\Borrow Pit Permit 2008\ChaffeeEnvAssessMining.doc
Survey. There are no standing structures within the Proposed Borrow Area, and there is no
evidence of residual foundations from early structures.
Historic and archeological resources on and in the vicinity of the Chaffee facility would not be
affected by development of the Proposed Borrow Area.
3.8 OPEN SPACE AND RECREATION
Open space and recreation on and in the vicinity of the Chaffee facility would not be affected
by development of the Proposed Borrow Area. Chaffee owns all land impacted by the
Proposed Borrow Area. Post closure plans for the soil borrow areas are to create an open
wildlife habitat area.
3.9 CRITICAL ENVIRONMENTAL AREAS
There are no critical environmental areas on or in the vicinity of the Chaffee facility.
3.10 TRANSPORTATION AND TRAFFIC
Traffic is one area of potential environmental impact where the Proposed Borrow Area will have
a beneficial effect. If on-site soils were not available for cell construction, soils would need to
be trucked in from off-site locations, using Route 16 and other local roads. Assuming the 1
million cubic yards of soil available from the Proposed Borrow Area were instead trucked to
the facility from off-site locations in 10 cubic yard loads, 100,000 truck trips would be
required.
Given these factors, when compared to the off-site alternative, it can be reasonably concluded
that the number of vehicles hauling soil to the Chaffee facility would be reduced by
development of the Proposed Borrow Area.
Soil Borrow Area–Environmental Assessment Report Chaffee Facility File: 00-016
Waste Management of New York Page 3-6 G:\Projects\Chaffee\Borrow Pit Permit 2008\ChaffeeEnvAssessMining.doc
3.11 ENERGY
The effect of the Proposed Borrow Area on energy consumption would be to increase the on-
site consumption of fuels (primarily diesel fuel) for excavation and transport of soils to the
construction area. This increase in energy use would be more than compensated by the
reduced energy consumption associated with the excavation and hauling of soils from off-site
locations.
Consumption of energy resources would be reduced by development of the Proposed Borrow
Area, compared to the off-site alternative.
3.12 NOISE AND ODOR
The change in noise impact related to the development of the Proposed Borrow Area, would relate
to the operation of excavation and transport equipment. Although the specific equipment to be
used and associated noise levels have not been determined, typical levels for excavators and off-
road haul trucks can be estimated from literature sources (e.g. see Reference 3). A very
conservative estimate of noise impacts at nearby receptors has been prepared and is summarized in
Table 1. For this conservative noise estimate, it was assumed that an excavator would be operating
under load, generating a noise level at 50 feet of 85 dBA, while an off-road haul truck would also
be operating under load, generating a noise level at 50 feet of 90 dBA. Attenuation was calculated
due to distance alone (no additional attenuation was included due to topography, vegetation, wind,
etc.), and maximum noise increases at the closest publicly accessible locations were estimated to be
from 6 to 4 dBA. Sound level increases of less than 5 dBA are considered to be "unnoticed to
tolerable" in NYSDEC Noise Guidance Document (Reference 4).
Though there is an increase in noise due to the development of the Proposed Borrow Area, it
should be noted that the reduction in truck traffic stated in Section 3.10 will reduce noise levels
along Route 16.
The potential odor impact associated with the Proposed Borrow Area would be nominal. Exhaust
fumes from mobile equipment would be the main odor source, and buffer distances to sensitive

receptors (approximately 2400 feet to the nearest locations) would be more than sufficient to
mitigate this impact.
Noise and odor impacts would not be significantly affected by the Proposed Borrow Area.
3.13 PUBLIC HEALTH
No change in the primary operation of the facility is being proposed. Quantities of fuels and
lubricants stored on-site will not increase significantly, and the existing “Spill Prevention
Control & Countermeasures Plan” will still be effective in reducing the risk associated with
release of these materials. Public health in the vicinity of the Chaffee facility would therefore
not be affected by development of the Proposed Borrow Area.
3.14 GROWTH AND CHARACTER OF COMMUNITY
Growth and character of the community in the vicinity of the Chaffee facility would not be affected
by development of the Proposed Borrow Area.
