1.0 INTRODUCTION
In accordance with Title 6 New York Codes, Rules and Regulations (6 NYCRR)
Part 360, this Monitoring and Maintenance Manual has been prepared to provide 30-year post
closure care and monitoring following the closure of the Southold Landfill, Cutchogue, New
York.
1.1 Site Description and History
The Southold Landfill is an inactive municipal landfill located between Oregon Road and
North Road (also known as Middle Road and County Road 48) to the north and south,
respectively, and Cox Lane and Depot Lane to the east and west, respectively, Suffolk County,
New York (see Figure 1-1). The landfill is situated in a rural, agricultural area of Cutchogue,
approximately 2.5 miles east of Mattituck and 8 miles west of the Incorporated Village of
Greenport.
The landfill property is approximately 62 acres, including the 17 acres north of the
landfill which was formerly used for borrow operations and 11 acres south of the landfill
currently used as a waste collection and recycling center and transfer facility. The area formally
used for landfilling, including two former scavenger waste lagoons located in the western portion
of the landfill, comprises 34 acres.
The Town of Southold initiated operations at the landfill site in 1920 for the disposal of
municipal solid waste, refuse, debris and scavenger (septic system) waste, and operated the
landfill continuously until 1993, when it was closed.
1.2 Landfill Closure Design
The current contour elevations and drainage characteristics of the closed Southold
Landfill (see Figure 1-2) reflect the intent of the New York State Department of Environmental
Conservation (NYSDEC) approved Final Closure Plan design and the results of construction

activities for closure/capping of the landfill. For the purposes of the following discussion, and
consistent with design of the subgrade grading plan, the landfill is divided into eastern and
western sections, which are delineated by the main access road which runs in a north/south
direction through the center of the landfill cap area.
The final cover for the Southold Landfill was designed to: (1) support vegetation;
(2)protect the hydraulic barrier layer (i.e., the geomembrane) from physical damage; (3)restrict
precipitation from infiltrating the landfill waste mass; and (4)provide collection and passive
venting of the landfill gases. The installed capping system consists of the following, from the
surface downward:
• Topsoil Layer: A 6-inch surface layer of uncompacted soil capable of supporting
vegetation;
• Barrier Protection Layer: A 12-inch layer of clean fill;
• Geocomposite Drainage Layer: A fabricated composite consisting of a geosynthetic
(polyethylene) drainage layer(geonet) core with a nonwoven geotextile (8 oz./sq. yd.,
polyethylene) permanently bonded to each side of the geosynthetic drainage layer,
which was installed in all drainage swales and over areas with slopes of 20 percent or
greater;
• Geomembrane Cap: Ahigh-density textured 60-mil flexible polyethylene (HDPE)
geosynthetic liner;
• Gas Venting Layer: A 12-inch layer of sand with a minimum coefficient of
permeability of 1 x 10-3 cm/sec. Passive gas vents are placed within the sand to
collect gas from this layer and vent the gases to the atmosphere; and
• Prepared Subgrade: The prepared subgrade surface serves as the graded and
compacted surface upon which the veneered layers of the capping system are
sequentially constructed. The prepared subgrade surface was achieved through a
combination of activities which included: excavation of waste in areas of cut,
relandfilling of excavated waste in areas of fill, and placement of contour grading
material (general fill) to achieve the proposed subgrade contours. The subgrade was
completed within a 6-inch layer of soil. Because the final subgrade layer and gas
venting layer comprised the same material, no geotextile was used between these two
layers.
The above-described capping system was constructed over the entire landfill waste mass.
♦1314\r0313301.doc(R05) 1-4
1.3 Purpose and Scope
The purpose of the Southold Landfill Post-Closure Monitoring and Maintenance Manual
is to define the procedures for personnel performing routine inspection, maintenance or repair
work on the landfill following its closure. The Manual is based upon the site remaining in an as-
built and fully passive state. Any change in use requires Town and NYSDEC approval and
revision, update and/or modification of this Manual. This Manual has been prepared in
accordance with 6 NYCRR Part 360 requirements effective November 24, 1999. The Manual is
intended to ensure the following:
• Site is maintained effectively and efficiently;
• Site is monitored for the prescribed parameters;
• All parties are aware of the specific monitoring and maintenance needs of the site;
and
• Provide a smooth transition of the site from the closure construction phase to the
post-closure monitoring and maintenance phase.
The guidelines and procedures presented in this Manual are based on site-specific
information, including:
• Site visits
• Southold Landfill General Construction Contract(Contract No. 2000)
• Southold Landfill Final Closure Plan
• As-built construction conditions
The Post-Closure Monitoring and Maintenance Manual includes the following

Section 2
2.0 SITE INSPECTION GUIDELINES
Following the closure of the Southold Landfill, the site will be monitored in accordance
with 6 NYCRR Part 360-2.15 criteria. The monitoring process requires the inspection of the site
at least four times a year by qualified, trained landfill personnel. In addition, inspections will
also be performed after a specified rainfall event (5-year storm or greater as required by NYCRR
Part 360). The results of these inspections will be recorded on the Post-Closure Site Inspection
Checklist, a copy of which is provided in Appendix A. The location and extent of any damage
discovered during an inspection will be noted on the inspection checklist form, along with any
necessary additional information. Any irregularities found during these site inspections will be
remediated according to the guidelines provided in Section 3 of this Manual. A copy of all the
inspection reports will be maintained on file in the offices of the Town of Southold Solid Waste
Coordinator located at the landfill site and included in the facility's annual report.
2.1 Cap Integrity
During closure construction, a minimum of 18 inches of soil cover was placed over the
geomembrane. The cap must be inspected to assure its continued integrity.
2.1.1 Soil Cover
The soil cover will be visually inspected for signs of erosion damage, settlement,
cracking, vectors, leachate or waste breakthrough, vandalism, litter and unauthorized dumping.
Erosion, settlement or cracking of the cover soil will be considered damaging, based upon
whether the function of the final cover had been impaired in the affected area, e.g.,ponded storm
water. The minimum final cover thickness must be maintained at 18 inches.
The Town will perform visual observation to determine if settlement has occurred. The
following will be noted on inspection logs:
• Visible debris or litter(housekeeping);
♦13 MR0313302.DOC(R06) 2-1
• Visible waste (indication of damage to the cap);
• Signs of unauthorized dumping or vandalism, such as vehicular tracks or disturbed
cover soil; and
• Evidence of surface leachate (indication of damage to the cap).
2.1.2 Vegetation
The soil cover was vegetated during the cap construction according to the seeding
specifications approved through the submittal process. Inspections of the vegetation will be
performed to monitor the vegetative growth and identify problem areas which require reseeding.
The vegetative cover will be inspected for bare spots, dead species and undesirable species. Bare
I
or dead areas of vegetation will be further examined for the possibility of landfill gas, erosion or
vector damage. The apparent cause of any damage will be noted in the inspection report.
2.2 Storm Water Collection and Recharge System
The storm water collection system for the Southold Landfill closure construction consists
' of open drainage swales, subsurface piping and drainage structures (such as a stilling basin, catch
basins, headwalls and manholes), which convey collected storm water runoff to the three on-site
groundwater recharge basins (see Figure 1-2).
1 Each of these structures will be monitored for wear or damage and the results of these
inspections will be reported in the inspection logs. Any necessary repairs will be performed in
according to the guidelines provided in Section 3 of this Manual.
All of the storm water collection, conveyance, drainage and control structures will be
visually inspected for obstructions, siltation, ponded water and erosion damage, such as
washouts. The location of any obstruction or damage and its cause, if known, will be noted in
the inspection logs. Drainage swales will also be inspected for loss of vegetation, collection of
debris or damage to the erosion control fabric.
♦1314Ut0313302.DOQR06) 2-2
The drainage swales for Recharge Basin 2 consist of a section of reno mattresses and stone
fill. The drainage swales for Recharge Basin 3 consist of a section of reno mattresses and stone fill
followed by riprap aprons. The stilling basin,manholes and catch basin for Recharge Basins 1 and 3
are constructed of precast concrete. The headwalls and apron for Recharge Basins 1 and 3 are
constructed of cast-in-place concrete followed by riprap and stone fill. These structures will be
examined for damage or instability which could affect their performance. Erosion of soil beneath or
around the structures or reno mattresses, or signs of slippage of the structures, will be noted on the
inspection logs.
2.2.1 Diversion Swales and Gravity Storm Water Drains
Open drainage swales were constructed to convey storm water runoff from the landfill
without damaging the integrity of the cap. The northern swales receive storm water runoff via
diversion swales from the northern portion of the eastern and western halves of the landfill.
Storm water from the northeastern and eastern portions of the landfill is discharged to Recharge
Basin 3 and storm water from the northwestern portion of the landfill is discharged to Recharge
Basin 2. The southern swales receiving storm water runoff discharge to a drain system which
discharges to Recharge Basin 1. Recharge Basins 1 and 3 also receive storm water from gravity
storm water drains along the southwestern and eastern edges of the landfill, respectively. The
drainage swales, stilling basin, catch basins and manholes will be examined on a regular basis for
signs of debris erosion and/or sediment buildup, and noted in the inspection logs.
On occasion, storm water control structures may become damaged and diminished in
function by intense rainfall events or by alternating freeze-thaw cycles. Stone fill is particularly
susceptible to movement by erosion and undermining. Care should be taken to inspect reno
mattresses, as well as the diversion swales,after intense rainfall events. If erosion or undermining is
observed, the Town should notify NYSDEC immediately and corrective action should be taken.
Any obstructions found in and along the storm water collection route will be promptly removed.
Eroded vegetated areas will be promptly filled with imported soil fill, compacted and
seeded. Eroded or undermined armored channels, such as areas with reno mattress, will have the
♦1314\R0313302.DOC(R06) 2-3
' subgrade material repaired with material equivalent to the original construction and the mattress
area repaired or replaced,also with material equivalent to that used in the original construction. Any
sediment buildup will also be promptly removed with hand tools and will be spread over existing
grassed sideslopes.
2.2.2 Recharge Basins
The groundwater recharge basins, located on the northeast, northwest and southwest
corners of the landfill, receive storm water discharge from the landfill. Periodic removal of silt
and other fines may be necessary to maintain the proper functioning of the three recharge basins.
The recharge basins' sideslopes will be periodically inspected and monitored for signs of erosion
and repairs will be made, if required.
2.3 Access and Maintenance Roads
The access and maintenance roads for the Southold Landfill consist of a main access
road, an east maintenance road, a west maintenance road and a middle maintenance road.
Portions of the west maintenance road and the main access road are paved, while the remaining
roads are constructed of a recycled concrete aggregate having a minimum thickness of 6 inches
(Figure 1-2). Visual inspections of the roads will be conducted for potholes, erosion gullies, loss
of aggregate cover and obstructions. The results of these inspections will be noted on the
inspection logs and repairs made, if required.
2.4 Landfill Gas Monitoring
A passive venting system was installed on the landfill to allow venting of landfill gases
through the geomembrane. During the post-closure monitoring period, these vents will be
inspected for damage, such as excessive settlement which causes stress on the geomembrane or
signs of vandalism. The vents will also be inspected for signs of vector infestation. The
inspection report will reflect any damage noticed during the inspection. The functioning of these
♦1314\R0313302.DOC(R06) 2-4
1 vents will be monitored during air quality testing which will be performed at the site according to
the guidelines provided in Section 5 of this Manual.
Perimeter landfill gas migration control trenches are located in areas along portions of the
northern, southern, western and eastern property boundaries. These trenches were constructed to
control off-site migration of landfill gas. These trenches were constructed to a depth of 10 feet,
lined with geotextile and filled with gravel. These trenches will likely not require any maintenance
during the post-closure period.
Fifteen perimeter gas monitoring wells are located at approximately 200-foot intervals along
the southern, western and eastern property boundaries. These wells are located at the property
boundaries beyond the gas migration control trenches. Explosive gas monitoring at these wells will
be performed regularly during the post-closure period. Explosive gas monitoring will also be
performed in the scale house and at the six gas vents in the collection center. The intent of the
regular monitoring at these locations is to identify the presence and concentration of explosive gases
and determine the extent of landfill gas migration, and to determine if corrective action is necessary
to mitigate gas migration.
' Gas monitoring wells will be visually examined during each routine inspection and the
functioning of each well will be checked during each monitoring event. The details of the gas
monitoring program are presented in Section 5 of this Manual. If a monitoring well sustains
damage or cannot provide a representative gas reading, the well will be examined to determine
' whether the problem can be corrected. This determination will be facilitated by comparing data
from previous monitoring activities.
The inspection report will include the details of any gas monitoring well damage and the
appropriate action that will be taken to correct the problem, as presented in Section 3 of this
Manual.
♦1314\R0313302.DOC(R06) 2-5
2.5 Groundwater Monitoring Wells
Twelve groundwater monitoring wells are installed at six locations at the landfill. Each
location comprises two wells, one shallow (water table) and one deep (approximately 100 feet
below the water table). Two wells are located upgradient of the landfill to determine
background/ambient groundwater quality, and the remaining wells are downgradient to monitor
landfills impacts on groundwater quality.
' Groundwater monitoring wells will be visually examined during each routine inspection and
the functioning of each well will be checked during each quarterly sampling event. The details of
the groundwater sampling program are presented in Section 4 of this Manual. If a monitoring well
sustains damage, or cannot provide representative groundwater samples, the well will be evaluated
to determine whether the problem can be corrected. This determination will be facilitated by
comparing data from previous monitoring activities to determine the cause of the problem. In
particular,the following signs of damages or deterioration will be examined:
i • Encrustation and corrosion;
' • An exceptional increase in solids content(e.g., from the breakdown of the screen);
An appreciable decrease in groundwater elevation, perhaps the result of these
problems.
The inspection report will include details of any well damage and the appropriate-action that
will be taken to correct the problem, as presented in Section 3 of this Manual. Damaged wells that
cannot be rehabilitated will be decommissioned by appropriate methods(i.e.,overdrilling,pulling of
casing or grouting in place) and replaced by construction of a replacement groundwater monitoring
well to re-establish the integrity of the sampling plan for groundwater monitoring.
♦1314\R0313302.DOC(R06) 2-6
' 2.6 Site Perimeter Fencing
' Site perimeter fencing consists of 6 or 12-foot high chain link fence and temporary fencing
on the eastern boundary of the landfill. The gates for the site are located on the east side of the
' landfill on Cox Lane and on the south side of the landfill on Middle Road.
iThe fencing will be visually inspected for any signs of vandalism or trespass including, but
not limited to,damaged or cut fence fabric, bent fence posts,rails or gates,damaged locks or chains,
' etc., and repairs will be made, if required.

♦1314\R0313302.DOC(R06) 2-7
Section 3
3.0 MAINTENANCE AND REPAIR PROCEDURES
The need for maintenance or repair work will be governed by the observations made
during the regular site inspections previously described in Section 2, and records of this work
' will be maintained in the permanent landfill files at the Town. This section describes the
maintenance and repair procedures which will be followed during the post-closure inspection and
' monitoring period for the Southold Landfill. The personnel and equipment requirements for this
30-year period are presented in Section 6 of this Manual.
3.1 Maintenance
Routine maintenance work will be performed, as necessary, during the 30-year post-
closure monitoring period. Mowing, regrading of the cover soils, access and maintenance road
repair, additional seeding, vector control and the removal of undesirable vegetation species are
considered typical maintenance tasks and are discussed in this section.
3.1.1 Landfill Gas Control
' In addition to the landfill gas monitoring program that will occur at the perimeter
monitoring wells, maintenance of the gas vents will also occur. During the post-closure period,
the vents will be inspected and maintained on a regular basis.
r3.1.2 Drainage and Erosion Control
Surface drainage features to control and convey storm water runoff have been designed
for the 100-year, 24-hour storm. The groundwater recharge basin system has also been designed
for the 100-year, 24-hour storm. The drainage swales will be maintained with grassed channels.
Complete vegetative coverage will be maintained and will be inspected at the same time the
landfill cap is inspected. Areas of erosion will be noted and repaired as soon as possible to
maintain the integrity of the cap. Discharge areas will be inspected for foreign debris and
sediment which may interfere with its proper functioning, and for areas of erosion which may
♦1314\R0313303.D0QR03) 3-1
' sediment which may interfere with its proper functioning, and for areas of erosion which may
degrade the integrity of the cap. The recharge basins will be kept free of litter and foreign objects
' that would inhibit groundwater recharge and degrade the integrity of the sideslopes and basin
floors. Vegetation species that would inhibit access for maintenance purposes will be removed.
' In addition, the accumulation of silt on the basin floors which interfere with recharge will be
' removed by periodic scraping of the basin bottom.
The gravity storm water drain piping, catch basins, stilling basin and manholes will be
periodically inspected for debris, sedimentation and visual settlement of the catch basin, stilling
basin and manhole structures. Debris and sediment in the piping, catch basins, stilling basin or
manhole structures will be periodically cleaned. The cleaning will consist of rodding or flushing
of the pipeline with appropriate sewer cleaning devices and hand or equipment excavation of the
interiors of manholes and catch basins. If entry into any of the catch basins, stilling basin or
' manholes is required, continuous gas monitoring and ventilation of these structures with an
explosion proof blower will be implemented, along with confined space entry procedures.
3.1.3 Vegetative Cover
The vegetative (grass) cover will be mowed at the discretion of the Town to control the
growth of wild and deep-rooted species, and to minimize the potential for the introduction of
vector habitats. The frequency of each mowing event will be determined by the site conditions.
' Undesirable species, such as saplings or other vegetation with penetrating roots discovered
during inspections, will be removed if their presence poses a threat to the integrity of the final
cover system. Herbicides and insecticides will not be used to control undesirable plant and/or
' animal species unless the nonchemical methods do not yield desired results. NYSDEC will be
notified of the use of herbicides and insecticides prior to use. Areas of the cap with dead
' vegetation or lack of vegetation will be inspected by qualified personnel for possible causes of
defoliation and devegetation. Bare areas of the cap will be seeded according to the seeding
' specification provided in the Landfill Closure Construction Contract Documents (Contract
No. 2000).
♦1314\R0313303.DOC(R03) 3-2
3.1.4 Regrading
' The effects of landfill subsidence, vandalism or gulleying from minor precipitation events
(i.e., not causing extensive damage to the site) may result in the need to reestablish the affected
' areas of the cap system. The areas of erosion or landfill subsidence which affect the performance
of the cap system will be restored to original grade to prevent surface ponding and further
' collection of water on the cap membrane. Deterioration of the access and maintenance roads will
be repaired by regrading where possible, by the placement of additional RCA or repaving, if
' necessary, to provide access for routine inspections and maintenance activities. If vandalism is
detected on the site, such as off-road vehicle tracks, the Town will pursue additional efforts to
' further restrict access to the site.
3.1.5 Vector Control and Aesthetics
Vectors common to active landfill operations are not expected to be a problem at the
closed landfill. However, suspected rodent or insect infestation will be addressed by contacting
qualified licensed exterminators. Prior to initiating an extermination program, the Town will
advise the NYSDEC of the situation and, if necessary, develop and submit to NYSDEC an
' extermination work plan for review and approval. Details of the communication procedures for
nonroutine events are provided in Section 9 of this Manual.
3.1.6 Access
Access to, and onto the landfill will be continually maintained. Vehicular access will be
limited to authorized personnel and will only be accomplished through the main site entrance off
County Road 48 and exit onto County Road 48, Cox Lane or the Town's Compost Facility along
the western boundary of the landfill. The access and maintenance roadways will be inspected for
foreign objects and vegetative growth which could degrade their integrity and inhibit access.
♦1314a0313303.DOC(R03) 3-3
3.1.7 Fencing
A six-foot high chain link security fence surrounds the majority of the perimeter of the site
with 12-foot high chain link fence in the vicinity of the collection center/transfer station. Two
20-foot wide double leaf gates are located at the entrance from Middle Road and Cox's Lane.
Periodic inspections will be made of the fences to determine if they have been damaged by vandals
or the weather. Routine repairs will be made to damaged sections using the same type and quality
materials as were used in the original fence installation.
3.2 Repairs
This section details the procedures which could be used to perform nonroutine repairs of
Lthe cap system and, as such, are considered to be outside of the scope of the normal maintenance
procedures for the landfill. These activities may include, but not be limited to, repair of storm
water structures, the geomembrane, gas vents, landfill gas monitoring wells, groundwater
monitoring wells and the vegetative cover.
3.2.1 Storm Water Structures
Should settlement of the gravity storm water drain piping, manholes, catch basins or
stilling basin be observed during routine maintenance and cleaning of the pipeline and structures,
the Town will monitor the area where the settlement has occurred in order to determine the
nature of the settlement and whether the geomembrane cap may have been damaged or
disrupted.
3.2.2 Geomembrane
If the geomembrane cap has been damaged or disrupted, the Town will immediately notify
the NYSDEC of the problem and propose a plan to repair the liner. This proposed plan will
incorporate the requirements for repair of the cap membrane. Upon approval by the NYSDEC of the
proposed repairs,the Town will proceed and implement the repairs as set forth in the proposal.
♦1314\R0313303.DOC(R03) 3-4
Once the geomembrane cap has been repaired, or if excavation reveals that the
geomembrane cap has not been damaged, the Town will backfill the area of settlement with
compacted backfill material. Proper construction procedures will be followed as set forth in the
closure design drawings and specifications for the Southold Landfill.
3.2.3 Gas Venting System
Landfill gas vent damage will most likely occur during normal maintenance of the site,
such as during mowing. If damage occurs to a gas vent,the vent will be replaced according to the
approved closure construction documents. Breakage of landfill vents, which can damage the
membrane beneath-the cover soils or the watertight seal around the pipe penetration, will be
�j examined. The cover soils will be removed and the membrane and pipe penetration boot
inspected for damage. If damage has not occurred, the soil layers around the vent will be
replaced by hand and compacted to a minimum thickness of 18 inches. All repairs will be such
that replacement layers will match and tie directly into the undisturbed portion of the cap.
Damage to the membrane or the pipe penetration boot will be repaired according to the
guidelines provided in Section 3 of this Manual.
3.2.4 Landfill Gas Monitoring Wells
The repairs required for the landfill gas monitoring wells may involve installation of a
new monitoring well. Repair of the well will be based on the extent of the damage observed and
the corrective action will be discussed with and approved by the NYSDEC prior to their
implementation.
Abandonment of the well will be performed in accordance with the closure construction
documents and will include, but not be limited to,the following procedures:
' • Removal of surface protective casing and concrete slabs, as appropriate;
♦1314\R0313303.DOC(R03) 3-5
• Overboring and removal of the casing, if present, to the greatest extent possible
(minimum 5 feet);
• Perforation of any casing remaining in the borehole;
• Pressure grouting of the borehole from the base of the borehole with cement-
bentonite grout to a depth of 5 feet below the ground surface using the tremie method;
• Backfilling the remaining 5 feet with native soil and compacting to avoid settlement;
• Grouted area will be periodically inspected or possible settlement; and
A If subsequent settlement occurs, soil will be placed into the depression and repacked
to grade level. If severe settlement occurs, the settled portion will be regrouted and
backfilled with soil.
3.2.5 Groundwater Monitoring Wells
The repairs required for groundwater monitoring wells may involve:
1. Redevelopment of the well;
2. Removal and replacement of the well screen, or
3. The installation of a new monitoring well.
The repair technique used will be determined by the extent of the damage observed.
However, any corrective measures will be discussed with and approved by the NYSDEC prior to
implementation.
Damaged monitoring wells that cannot be rehabilitated will be abandoned in accordance
with the closure construction documents to prevent potential contaminant migration downward
through/along the monitoring well.
' The monitoring well abandonment procedures will follow NYSDEC protocols and
comprise the following:

4.0 GROUNDWATER MONITORING PLAN
The procedures described below will be followed during the sampling and analysis of
samples associated with the groundwater monitoring plan. These procedures are expected to
tcontinue to be followed for all routine sampling and analysis of groundwater conducted at the
landfill. Detailed sample collection and quality assurance control procedures and requirements
are provided in Appendix B.
The groundwater monitoring well network consists of six existing and six new
monitoring wells at the landfill (see Figure 1-2). Groundwater sampling will be conducted on a
quarterly basis, with three of the quarters consisting of analysis for 6 NYCRR Part 360 Routine
Parameters and one quarter consisting of analysis for Baseline Parameters. Quarterly sampling
will be conducted for a minimum of 2 years. Once a baseline has been established, the results
will be evaluated to determine if the frequency, number of wells and monitoring parameters can
be modified/reduced. During each sampling event, each well will be purged a minimum of three
well volumes prior to sample retrieval. Either dedicated or disposable bailers will be used to
collect samples after this purging procedure. Chain of custody documents for each sample
retrieved will be maintained by both the Town and the laboratory performing the quarterly
sampling and analysis.
Field measurements will be obtained for temperature, conductivity and pH, and the static
water level of each well will be determined prior to purging each groundwater monitoring well.
The results of the groundwater sample results will be provided to NYSDEC.

5.0 LANDFILL GAS MONITORING PLAN
The purpose of the landfill gas monitoring plan, which will be conducted on a quarterly
basis for the first 3 years of the post-closure period and modified accordingly thereafter, is to
detect the possible migration of methane gas across the boundaries of the site to neighboring
properties before the gas becomes a hazard to the public safety. The procedure for methane gas
monitoring and the Landfill Gas Monitoring Form are contained in Appendix C.
' Each of the 15 landfill gas monitoring wells will be monitored for the percent of methane
accumulated in the well's atmosphere. The locations of these monitoring wells are shown in
Figure 1-2. In addition, explosive gas monitoring will be performed at the scale house and the
six gas vents located in the collection center. The results of the monitoring will be submitted to
the NYSDEC. Any indication of dangerous levels of methane in the wells will be reported to the
appropriate authorities for immediate action. The lower explosive limit (LEL) of methane is 5
percent, by volume, in air. When levels of methane reach 25 percent of this amount, the
Contingency Plan, as described in Section 7, will be implemented. The Contingency Plan
identifies the appropriate authorities to contact should excessive levels of methane be detected.
♦1314\R0313305.DOC(R04) 5-1
Section 6
6.0 PERSONNEL AND EQUIPMENT REQUIREMENTS
MThe post-closure monitoring of the Southold Landfill will be performed by the Town of
Southold personnel or subcontractors retained for this purpose. Town personnel or
subcontractors retained for this purpose will be responsible for the entire site's routine operation
and maintenance. In the event that a component of the landfill becomes damaged, inoperative or
requires repair, the procedures outlined in Section 3 of this Manual will be followed. The
personnel and equipment requirements described below represent an estimate of the time that
will be required to maintain and repair the landfill closure system. This estimate assumes that
major storm events (i.e., those causing extensive damage to the landfill site) will not occur
tduring the post-closure period and that other contingencies will not occur as discussed in
Sections 7 and 9 of this Manual.
l
6.1 Staffing Plan
The personnel required to conduct quarterly inspections and perform routine maintenance
and repairs will be furnished on a part-time basis. Periodic training will be provided to Town
personnel to satisfy the requirements for the monitoring and maintenance activities at the landfill.
Equipment needed for operations and maintenance activities will be provided by the Town on an
as-needed basis during the post-closure period. For events occurring outside the scope of the
routine maintenance and repair program, the guidance described in Sections 7 and 9 of this
Manual will be followed. Sections 6.1.1 and 6.1.2 provide a summary of the required training
for monitoring and maintenance personnel. Records will be routinely kept for Town personnel
and are described in Section 10 of this Manual.
6.1.1 Staff Training
Selected Town personnel should be trained on specific duties at the site. These personnel
should be given additional training in the recognition of, and response techniques to first aid,
confined space entry and basic firefighting. These training programs will be updated annually
and as newly developed procedures are implemented. The Town's personnel training will
♦1314\R0319302.doc(R04) C-1
include conducting comparative data (laboratory and field) analyses and identifying when
significant changes occur in data from period to period, as well as identifying unusual
roccurrences. If unusual circumstances or conditions occur, the Town will make arrangements for
and acquire professional assistance, if required. Evaluations of alternatives and implementation of
solutions will be directed by the Town.
6.1.2 Safety Plan
rThe Southold Landfill after closure is not expected to expose personnel to waste or
hazardous substances, and routine monitoring and maintenance activities are expected to be
conducted using general site safety equipment personal protective equipment under normal
conditions. Health and safety procedures for the performance of routine operations and maintenance
of the site are outlined in this section. A site specific health and safety plan for the closure of the
landfill was prepared by the construction contractor to address the conditions associated with the
iconstruction of the landfill capping system and appurtenances. This plan is provided as a reference
document and as a resource in the event that extensive or invasive activities or repairs become
necessary in the future. The document may need to be updated to address the activities to be
undertaken.
Personnel involved in the post closure monitoring and maintenance of the landfill should
familiarize themselves with the health and safety program which was implemented during closure
construction, but should recognize that it represents conditions with heavy construction, earthwork
and activities directly involving the excavation and relandfilling waste.
Based on available information, it appears that the landfill contains the following potential
chemical and physical hazards:
• Methane gas;
• Open drainage swales;
• Large diameter drainage piping,manholes,catch basins and stilling basin;
♦1314\R0319302.doc(R04) 6-2
• Recharge basins;
• Severe weather; and
• Deer ticks.
The items listed above o e are not meant to be all inclusive, but are a minimum listing of
hazards which should be taken into consideration during the post-closure monitoring and
maintenance period, and which should be considered in the approach taken during post-closure
' activities. The Town should include other hazards as it determines appropriate. The landfill
personnel must be made aware of these potential hazards, given special instructions as needed, and
utilize issued safety equipment(as necessary), all in conformance with the Town's health and safety
program, and in conformance with the Occupational Safety and Health Administration (OSHA)
requirements.
Methane Gas
Methane, an odorless, colorless and tasteless gas, is an asphyxiant under high
concentrations. There are no systemic effects, either at 5 percent concentration or for long-term
' exposure. Neither are there any OSHA Permissible Exposure Limit (PEL), National Institute of
Occupational Safety and Health(NIOSH)recommended exposure limit,or American Conference of
Governmental Industrial Hygienists (ACGIH)threshold limit values. The prime concern associated
with methane is the hazard of fire and explosion. The Lower Explosive Limit(LEL) for methane is
5 percent of air volume and the Upper Explosive Limit(UEL)is 15 percent of air by volume.
Post-closure monitoring personnel must be aware of: 1)the presence of methane gas on
site; 2)the potential hazards associated with methane gas; and 3)the procedures to be followed to
detect methane. Personnel must avoid generating arcs, sparks or flames in areas where methane gas
is detected at levels of 10 percent of the LEL or greater and are prohibited from smoking on site.
An explosive gas/oxygen analyzer will be used to detect the presence of methane gas and determine
its concentration.
♦1314\R0319302.doc(R04) 6-3
Open Drainage Swales/Recharge Basins
There are drainage swales, approximately 2 to 3 feet deep, located throughout the landfill.
Three recharge basins are located at the site. Consistent with typical industry practice, the swales
rand recharge basins are not fenced and, therefore, could be a potential physical hazard to personnel
traveling across the site. Personnel performing inspection, maintenance or repair work at the
landfill should be aware of this potential hazard and the necessary precautions needed to be taken to
avoid it becoming a hazard.
Large Diameter Drainage Piping, Manholes, Catch Basins and Stilling Basin
Along the southwest and eastern portion of the landfill are drainage systems which includes
a series of open drainage swales which discharge into a buried 24-to 36-inch diameter gravity storm
water drain. There are several manholes, catch basins and a stilling basin as part of the buried
gravity storm water drain systems which provide access to the pipe system. It is expected that all of
these buried structures will require periodic inspection, cleaning and maintenance. Prior to entering
any of these buried structures for any purpose, it is imperative that they be tested for the presence of
gases, particularly methane. Confined space procedures should be implemented by personnel when
' entering and working in these areas.
' Severe Weather
The Southold Landfill is open and exposed to both the sun and the wind, which can
aggravate extremes of temperature. In the winter, there is little protection from the wind, and in
summer, there is no screening from the sun. These conditions can potentially contribute to physical
hazards, such as hypothermia, dehydration and frostbite in the cold weather, and heat rash, heat
cramps, heat exhaustion and heat stroke in hot weather. Personnel performing inspections,
maintenance and repair work at the landfill will be advised of the severe weather hazards and
necessary precautions as part of the safety orientation program.
♦1314\R0319302.doc(R04) 6-4
Deer Ticks
Personnel working at the landfill should take the precautions described below against
possible deer tick bites. Deer ticks are carriers of the spirochete (borrelia bergdorfi), which causes
Lyme Disease,that can be transmitted to humans when bitten.
Signs and symptoms of Lyme disease may include the following:
r • The most well-known warning sign is a rash, classically described as a small red area
that starts at the site of a tick bite and gradually enlarges over several days. The rash,
' which does not appear until three to 30 days after the tick bite, may grow to several
inches in diameter and is circular with a central clearing. It may be obvious or very
faint. Multiple, usually smaller, rashes without central clearing may develop in some
individuals.
• Flu-like symptoms may precede or accompany the onset of the rash. Symptoms may
' include chills and fever, headache, malaise and fatigue, stiff neck and, in some cases,
pain in the joints.
• If the initial stage is not discovered and treated promptly, later stages may develop.
Chronic arthritis, and in some cases heart and nervous system disorders may develop
weeks to months after the tick bites.
Some infected individuals may not develop either rash or symptoms. Therefore, anyone
bitten or thought to be bitten by a deer tick, or developing signs or symptoms of Lyme Disease, is
advised to see a physician promptly for an examination and possibly a blood test.
To prevent tick bites,personnel should wear long pants made of light-colored,tightly woven
cloth;tuck pants legs inside of socks;use an insect repellant; check themselves frequently;and wash
themselves thoroughly at the end of each day.
6.2 Equipment
The equipment utilized for post-closure monitoring and maintenance of the Southold
Landfill will consist of standard construction equipment from the Town's inventory or from that of
♦1314\R0319302.doc(R04) 6-5
subcontractors retained by the Town for monitoring and maintenance purposes. In addition, the
Town's standard maintenance equipment, such as mowers and trimmers, will be used at the
discretion of the Town to maintain the site following its closure.
6.2.1 Minimum Requirements for Maintenance
The principal operations to be performed by the Town on a regular basis during the
post-closure period will be maintenance of the vegetative cover and the repair of cover soil erosion.
Mowing operations will require the use of a heavy equipment mower which can be operated safely
on steep sideslopes. The soils repair will be accomplished with a front-end loader, a vibratory drum
roller and a grader, as necessary, depending on the size and depth of the area which has been
eroded. This equipment may be available in the Town's inventory or will be rented or leased, or
provided by subcontractors retained by the Town for monitoring and maintenance purposes. The
equipment must be outfitted with rollover protection cabs and backup alarms meeting the OSHA
requirements for this type of machinery. The equipment will be maintained according to the
Town's current maintenance schedule and additional equipment for emergencies should available
from the inventory of subcontractors retained by the Town. Because the Town will utilize
necessary additional equipment from its subcontractors, resources will not be designated solely for
landfill post-closure activities at the landfill.
6.2.2 Firefighting Equipment
Fire extinguishers will be carried on all equipment used on the site for maintenance or repair
work. In addition, the local fire company will provide assistance and/or equipment, as needed, to
control any fires which may occur at the site.
♦1314\R0319302.doc(R04) C-6
Section 7
7.0 CONTINGENCY PLAN
' The objective of the Contingency Plan is to address the events which may occur outside
of the scope of the routine maintenance program. The Contingency Plan will be implemented
following the discovery of a condition at the landfill which cannot be covered by routine
scheduled maintenance and repair. Natural occurrences, such as storms, drought and landfill
' settlement, are considered "expected occurrences" and have been addressed in the previous
sections of this Manual. Other situations, such as war, an earthquake or other catastrophic events,
rcannot be reasonably expected to occur and, therefore, are not specifically addressed in this
Manual.
The Contingency Plan which follows addresses new degradation of the groundwater
quality, the migration of methane gas and the possibility of a fire on the landfill. The guidelines
which follow will be used to determine when the Contingency Plan should be implemented and
which corrective measures should be implemented. The appropriate regulatory agencies and
public officials will be notified of any emergency which is governed by this plan.
7.1 Groundwater Contamination
Groundwater will be monitored quarterly during the first 2 years of post-closure period
according to the provisions of Section 4 of this Manual. In the event that a statistically significant
' increase in the level of contamination emanating from the landfill via the groundwater pathway
occurs, the Town will notify the NYSDEC. Based on this occurrence, the next round of
sampling will include testing of the wells for the Part 360 Baseline Parameters. Should the
elevated levels continue, or if new contaminants are discovered, a work plan may be developed
that will investigate the nature, extent and cause of the contamination, including the possible
installation of additional groundwater monitoring wells.
' Upon development of the work plan and completion of the investigation involved, a
report will be prepared describing the findings of the investigation and providing
♦1314\R0313306.DOC(R05) 7-1
rrecommendations for corrective measures, if necessary. At a minimum, any corrective measure
will be accomplished in accordance with 6 NYCRR Part 360-2.20.
7.2 Landfill Gas Migration
r
Methane gas that is vented to the atmosphere does not present a risk to human health.
However, migration of gas off-site and a buildup of gas within a confined space may create an
explosion hazard. If it is suspected that methane gas generation poses a health hazard, the
rNYSDEC will be notified and an investigation undertaken to determine whether the vent system
is functioning properly. The possible responses to a gas venting problem include replacing
' portions of the venting system, adding new vents or venting trenches, or installing an active gas
withdrawal system.
Currently, a gas monitoring system exists along the southern, western and eastern
boundaries of the landfill. The landfill gas monitoring wells are designed to detect the presence
of methane migration. A description of the routine gas monitoring plan is provided in Section 5
of this Manual.
In the event that methane gas is detected at a level equal to, or greater than 25 percent of
the LEL (5 percent, by volume) during the monitoring period, the NYSDEC will be notified and
all steps necessary will be immediately undertaken to ensure safety and protection of human
health. If deemed necessary,the following will be implemented.
r
• Within seven days of detection, the Town will submit to the NYSDEC a report of the
methane gas levels detected and provide a description of the steps that will be taken
to protect human health; and
• Within 45 days of detection,the Town will submit a plan to implement a remediation
plan for the methane gas releases and a schedule for implementation of the plan
1 within 60 days after date of detection. The plan will assess the nature and extent of
the gas release problem and describe the proposed remedy.
r
♦1314\R0313306.DOC(R05) 7-2
r7.3 Fire and Explosion
The Southold Landfill has been inactive since 1993. As a result, the likelihood of an
underground fire in the waste is low. However, an aboveground (vegetation) fire is a possibility
and will be reported to the local fire department immediately if it occurs. The appropriate
response measure, including the safety of the personnel on the site, will be the responsibility of
the Fire Department. Any damage to the landfill closure structures will be repaired according to
the guidelines in Section 3 of this Manual after extinguishing the fire.
7.4 Emergency Response
Emergencies are events which fall outside of the reasonable range of occurrence and have
not been included in the Contingency Plan. Such events may include, but not limited to, a
catastrophic failure of one of the storm water control features or a catastrophic failure of the
landfill cap.
7.4.1 Notification Procedure
For emergencies that present an immediate danger or threat to human health and welfare,
the Police and Fire Departments will be notified, the affected area(s) secured and local residents
warned or evacuated. For emergencies that do not present an immediate threat or danger, the
NYSDEC will be notified.

' 8.0 POST-CLOSURE COST ESTIMATE
This section of the Manual provides an estimate of the costs expected to be incurred
during the post-closure monitoring and maintenance of the Southold Landfill. This annual cost
' estimate is based on 2003 dollars and is presented on Table 8-1. The projected cost of the three
basic components (inspection, monitoring and maintenance) is presented below. The total
projected cost during the 30-year post-closure period, based on quarterly inspection and
monitoring, and an escalation rate of 5 percent annually, is approximately $5,771,000. However,
certain variables may affect these estimated costs:
• The extent or severity of storms which exceed the design standards and result in
severe erosion or other natural calamities;
• Weather extremes, such as drought or extensive frozen ground;
• A change in groundwater quality which could require the installation of additional
monitoring wells or additional testing of the existing wells;
• A change in groundwater quality which could require less testing;
• Migration of landfill gas beyond the perimeter of the landfill which could require the
installation of additional monitoring wells or additional testing; and
• Increase in annual escalation rate, fees, special levies, changes in insurance rates or
other unexpected administrative costs.
' 8.1 Inspection Costs
It is assumed that it will take one person to perform the inspection at an hourly rate of
$50 per hour. Assuming that the inspection will be performed during a 4-hour period, this would
amount to $200 per inspection. The landfill will be inspected four times per year, therefore, the
annual estimated cost of performing the site inspections is estimated to be $800 per year.

' 8.2 Maintenance Costs
Routine maintenance of the landfill cap is anticipated to include three activities: 1) repair
of erosion damage to the landfill cap, drainage swales, access road and maintenance roads;
2)mowing landfill vegetation; and 3)removal of silt and debris from the drainage structures,
including the gravity storm water drainage systems and recharge basins. Estimating this work
requires assumptions based on previous post-closure monitoring experience, as well as a
knowledge of the site weather history. Repair costs will generally involve a minimum of two
workers and appropriate equipment. Routine repairs are anticipated to involve one 8-hour day
per specific component (e.g., drainage swales), and routine repair to the access and maintenance
roads and landfill cover system is anticipated to take two days for each occurrence.
On average, it is expected that the erosion repair and maintenance of the swales, stilling
basin, manholes, catch basins and drainage outlet structures will be performed twice per year.
Mowing (at the discretion of the Town) will occur once per year. Routine erosion repair of the
vegetative cover and to the roads will probably occur twice per year. The cost of these
maintenance services, including general site maintenance, is anticipated to average
approximately $16,760 annually (see Table 8-2). The cost of this maintenance work may be
greater during the first 3 years of the post-closure period as the vegetative cover develops, but is
expected to decrease to a lower value for the remainder of the 30-year post-closure period.
Other costs which may be incurred during the maintenance period include groundwater
and landfill gas monitoring, monitoring well repair or replacement, gas vent repair or
replacement, reconstruction of drainage structures, or repairs to the geomembrane or barrier
protection cover. These costs are contingent upon need and, therefore, are unable to be estimated
at this time. However, an amount equal to approximately 25 percent of the routine inspection and
maintenance costs is estimated for contingencies. This amount for these non-routine (contingent)
repairs is estimated to be approximately$4,240 per year. While it is not expected to be used each
year, it is anticipated that over the post-closure life of the facility, non-routine repairs will occur
that will necessitate the use of contingent monies. Unspent contingency budget monies should
be carried over, and accrued, from year to year.

8.3 Monitoring Costs
8.3.1 Groundwater Monitoring
j Twelve wells will be utilized to monitor groundwater during the post-closure period. It is
anticipated that well sampling will be conducted by two field personnel, and that two (8-hour)
days will be required for collection of a complete round of samples. With four rounds of
monitoring required each year, a field labor budget of$6,400 is anticipated.
Groundwater sampling will be conducted on a quarterly basis, with three of the quarters
consisting of analysis for Part 360 Routine Parameters and one quarter consisting of analysis for
Baseline Parameters for the first 2 years of sampling. The annual budget for laboratory analyses
of groundwater samples is estimated to be $19,600. An estimated cost of$8,000 per year will be
required to cover costs for sampling equipment resulting in a total annual groundwater
monitoring budget of$34,000 per annum.
8.3.2 Landfill Gas Monitoring
Gas monitoring will be conducted on a quarterly basis during post-closure period. This
involves the effort of one individual for a 4-hour day for each monitoring event. This results in a
labor and equipment expense of$9,600 on an annual basis.
♦1314\R0320303.DOC(R05) 8-5
Section 9
9.0 COMMUNICATION PROCEDURES
During the 30-year post-closure period at the Southold Landfill, routine inspections will
be performed quarterly as described in Section 2 of this Manual. In addition to these scheduled
inspections, non-routine inspections may be necessary as a result of extraordinary incidences
which may occur at the landfill, such as fires, natural disasters or significant vandalism.
Sections 2 and 3 of this Manual identify the procedures to be followed for routine site
inspections and scheduled maintenance and repair. The procedures outlined in Sections 2 and 3
will also be followed in the event that a non-routine inspection is required. This section of the
Manual outlines the recommended communication procedures to be followed in the event that a
component of the landfill site becomes damaged, inoperative or requires non-routine repairs.
Table 7-1 lists the telephone numbers of the appropriate authorities to contact in case of
emergencies.
9.1 Vandalism
Routine inspection of the soil cover will reveal if any unauthorized dumping or
vandalism has occurred on site. Should this occur, inspection personnel will record evidence of
such activity (e.g.,vehicle tracks) or attempt to identify source of the illegally placed waste and
those who caused the vandalism, and immediately notify the Town. One form of vandalism that
may occur on this landfill during the post-closure period will be the result of off-road vehicles
using the area. These vehicles tend to damage vegetation and create ruts, possibly exposing the
geomembrane and damaging it.
When vandalism, trespassing or unauthorized dumping has occurred, the Town will
evaluate site security procedures to identify the probable access route and will augment the
security procedures to prevent such access, as needed. If the site cannot be secured through the
use of existing resources, and the Town determines that additional labor or materials are needed
to protect the site,the Town will obtain an appropriate commitment of specialty resources.
♦1314\R0319303.D0QR03) 9-1
In addition, to determine if any of the landfill components have been damaged as the
result of significant vandalism, an emergency site inspection will take place. The Town Solid
Waste Coordinator will coordinate and direct all emergency repairs.
9.2 Fires
All Town equipment, or equipment used by subcontractors retained by the Town, used
for maintenance and/or repair work, will be equipped with fire extinguishers. However, should a
fire occur which cannot be contained by on-site personnel or equipment, the local fire
department will be contacted. In addition, the Town Solid Waste Coordinator will be notified
immediately so that he/she can coordinate the other on-site activities.
After a fire, the Town will determine if any of the landfill components were damaged. A
site investigation will be undertaken according to the procedures outlined in Section 2 of this
Manual. The Town will coordinate and direct all emergency repairs and notify the appropriate
agencies of any adverse conditions at the site.
9.3 Natural Disasters
Some natural disasters that might occur at the site may include, but not be limited to,
hurricanes, heavy rains, ice storms, lightning strikes and/or floods. Other natural phenomena,
such as tornadoes and seismic events, are unlikely to occur at the site due to its geographic
location. Should one or more of these events take place, Town personnel (or personnel of
subcontractors retained by the Town) will follow emergency procedures to ensure protection and
prevent personal injury during the event, and will notify the Town of any evident damage or
threatening conditions that have been created as a result of the event. Damage that might occur
as a result of such events includes erosion of the cover system and clogging of storm water
conveyance structures. Lightning strikes to trees could result in trees falling across site roadways
and fire.
♦131AR0319303.DOC(R03) 9-2
If a severe storm event or other natural phenomena has caused significant damage to the
landfill, or if the landfill has sustained significant damage, an emergency site inspection will be
undertaken to determine the extent of such damage. When the Town determines that conditions
are safe to inspect the site, it will dispatch a team of qualified personnel to inspect the site as
described in Section 2 of this Manual. The Town will coordinate and direct all emergency
repairs and notify the appropriate agencies of adverse conditions at the site.
9.4 Vectors
During site inspections, vector infestation may be evidenced by the presence of burrow
holes or nests. Should infestation be discovered to pose a potential threat to the integrity of the
landfill cover system or other site components, the Town will be notified of these conditions.
The Town will contact an appropriate extermination service to eliminate rodents or insects, as
needed.
9.5 Methane
The site will be monitored quarterly for methane at 15 locations to determine the percent
of methane accumulated within the landfill gas monitoring well's atmosphere. Methane gas
monitoring will also be performed in the scale house and six vents in the collection center. It is
expected that these procedures will be followed throughout the 30-year post-closure period. In
the event that the recorded methane levels exceed 25 percent of the lower explosive limit (LEL),
contingency planning will be implemented as described in Section 7 of this Manual.
9.6 Dust
Prolonged dry periods are not expected to present the same problems at the closed/capped
landfill as at an operating landfill because of the presence of vegetative cover. To prevent
blowing dust, the landfill cap must maintain complete vegetative cover. This will prevent the
cap from desiccation under prolonged dry conditions. However, during such periods, the use of
areas that are not vegetated(e.g., access roads)will be minimized.
♦1314Ut0319303.DOC(R03) 9-3
9.7 Storm Water Control System
The storm water control system will be inspected to determine if siltation has occurred or
if debris has accumulated which would impede the flow of storm water through the conveyance
system or recharge into the groundwater. In the event that siltation has occurred, it will be noted
on the inspection form and the Town will be notified so that the appropriate action can be taken
to clean the conveyance system or clean the recharge basin.
Drainage swales of the storm water conveyance system will be inspected for excessive
build-up of silt; the gravity drain, manholes, catch basins and stilling basin will be cleared of silt
and other debris; and the recharge basins will be scraped to remove silt and other fine particles
that would prevent or impede groundwater recharge.
9.8 Excessive Landfill Settlement
The landfill will periodically be visually inspected for cap integrity and differential
settlement to determine if a change has occurred which could indicate potential malfunction of
one of the landfill closure components. If it is determined through the evaluation that certain
areas have settled to the point where the integrity of the cap system may be jeopardized, the
Town will notify the NYSDEC. Upon a physical examination of the site by the Town and the
NYSDEC, a work plan will be prepared to repair any damage that may have been caused to the
landfill cover system.
9.9 Groundwater Contamination
Should there be a statistically significant increase in the level of contamination emanating
from the site via the groundwater pathway, the NYSDEC will be notified and the Town or its
subcontractor will monitor the Part 360 Baseline Parameters during the next round of sampling.
Should the elevated levels continue, or if new contaminants are discovered, the Town will
prepare a work plan to investigate the nature, extent and cause of the contamination. The work
i
♦1314\R0319303.DOC(R03) 9-4
plan will be submitted to the NYSDEC for approval. Following implementation of this work
plan, the results will be evaluated and recommendations for corrective measures will be made to
the NYSDEC.

1.0 QUALITY ASSURANCE/QUALITY CONTROL PLAN
1.1 Objective and Scope
The objective of this project is to provide post closure monitoring of the Southold
Landfill. The post closure monitoring program includes groundwater monitoring.
The purpose of this Quality Assurance/Quality Control (QA/QC) Plan is to develop and
describe the detailed sample collection and analytical procedures that will ensure high quality,
valid data for use during post closure monitoring.
1.2 Data Usage
The data generated from the field sampling program will be used to evaluate the
effectiveness of the landfill closure in accordance with Part 360. In addition, data will be used to
monitor health and safety of workers at the site and the health and safety of persons off-site.
1.3 Sampling Program Design and Rationale
The following presents a general discussion of the sampling to be conducted during
year 1 of post closure monitoring.
• Groundwater: Four rounds of 12 groundwater samples will be collected. Each round
will consist of one sample from each of the six newly installed wells and the six
existing wells.
For a discussion of the sampling program and sample locations, see Section 4.0 of the
Manual.
♦1314\A0314302.doc(R02) 1-1
1.4 Analytical Parameters
The first round of samples will be analyzed for Baseline Parameters as defined in
6 NYCRR Part 360-2.11(c)(6) "Water Quality Analysis Table" (see Attachment A). The
rsubsequent rounds of sampling will be collected at three-month intervals and analyzed for
Routine Parameters as described in 6 NYCRR Part 360-2.11(c)(6) "Water Quality Analysis
Table" (see Attachment A). If turbidity of a groundwater sample is greater than 50 NTUs, the
sample will be filtered for dissolved metals analyses. In such instances both filtered and
unfiltered samples will be analyzed for dissolved and total metals, respectively.
Table 1-1 presents a summary of the parameters/sample fractions to be analyzed together
with the sample location, type of sample, sample matrix, number of samples, frequency of
sample collection, type of sample container, method of sample preservation, holding time and
analytical method.
1.5 Data Quality Requirements and Assessment
Data quality requirements and assessments are provided in the 6/00 NYSDEC ASP,
which includes the detection limit for each parameter and sample matrix. Note that quantification
limits, estimated accuracy, accuracy protocol, estimate precision and precision protocol are
determined by the laboratory and will be in conformance with the requirements of the 6/00
NYSDEC ASP, where applicable. Table 1-2 presents a summary of the data quality
requirements.
In addition to meeting the requirements provided in the 6/00 NYSDEC ASP, the data
must also be useful in evaluating the nature and extent of contamination. Data obtained during
' post closure monitoring will be compared to specific SCGs. The SCGs to be utilized include:
Matrix SCG
Groundwater Division of Water Technical and Operational Guidance Series
(TOGs) (1.1.1) - Ambient Water Quality Standards and Guidance
Values, dated June 1998.

The methods of analysis will be in accordance with the 6/00 NYSDEC ASP. Specific
analytical procedures and laboratory QA/QC descriptions are not included in this QA/QC plan,
' but will be available upon request from the laboratory selected to perform the analyses. The
laboratory will be New York State Department of Health (NYSDOH) Environmental Laboratory
' Approved Program (ELAP) certified for organic and inorganic analyses, and also USEPA CLP
certified.
i
1.5.1 Data Representativeness
r
Representative samples will be collected as follows:
• Groundwater (Monitoring Well) - Samples will be obtained after the monitoring well
has been purged of three to five well casing volumes and field measurements (pH,
conductivity, temperature and turbidity) have stabilized, or until the well is purged
dry (whichever occurs first) and allowed to recharge. Samples will be collected with a
' dedicated polyethylene bailer.
• Equipment Calibration- Field equipment used for field measurements will be
calibrated daily before use according to the manufacturer's procedures.
• Equipment Decontamination-Nonsterile sampling equipment will be decontaminated
' prior to use at each location according to the NYSDEC approved procedures
described on Section 1.8 of this QA/QC Plan.
' 1.5.2 Data Comparability
All data will be presented in the units designated by the methods specified by a
NYSDOH ELAP and CLP certified laboratory, and the 6/00 NYSDEC ASP. In addition, sample
locations, collection procedures, and analytical methods from earlier studies will be evaluated for
' comparability with current procedures/methods.
♦1314W0314302.doc(R02) 1-11
1.5.3 Data Completeness
The acceptability of 100% of the data is desired as a goal for this project. The
acceptability of less than 100% complete data, meeting all laboratory QA/QC protocols/
standards,will be evaluated on a case-by-case basis.
1.6 Detailed Sampling Procedures
' Groundwater samples will be collected from different locations as part of the post closure
monitoring for the Southold Landfill. Sample locations will consist of monitoring wells.
Sampling procedures and equipment are described in this section. A summary of the sampling
program, including sample media, locations, depths, equipment, rationale and analytical
' parameters is provided in Table 1-3. Sample collection will be performed in conformance with
procedures described in Section 1.6.3.
The materials involved in groundwater sampling are critical to the collection of high
quality monitoring information, particularly where the analyses of volatile, pH sensitive or
reduced chemical constituents are of interest. Sterile disposable polyethylene bailers will be
rutilized for this project.
There will be several steps taken after the transfer of the water sample into the sample
container that are necessary to properly complete collection activities. Once the sample is
transferred into the appropriate container, the container will be capped and, if necessary, the
' outside of the container will be wiped with a clean paper towel to remove excess sampling
material. The container will not be submerged in water in an effort to clean it. Rather, if
' necessary, a clean paper towel moistened with distilled/deionized water will be used.
The sample container will then be properly labeled. Information such as sample number,
location, collection time and sample description will be recorded in the field logbook. Associated
forms (e.g., Chain of Custody forms) will then be completed and will stay with the sample. The
samples will be packaged in a manner that will allow the appropriate storage temperature (4°C)

1.6.1 Sample Identification
All samples collected during post closure monitoring at the Southold Landfill Site will be
labeled with a sample identification code. The code will identify the sample location, sample
matrix and series numbers for sample locations with more than one sample. Samples will be
labeled according to the following system:
• Sample Location: - Monitoring Well "MW
• Sample Matrix: - Water"W
• Sample Number: - For circumstances where more than one sample
of the same type and/or from the same location
will be collected, a consecutive sample number
will be assigned.

1.6.2 Sample Handling, Packaging p �, ging and Shipping
All analytical samples will be placed in the appropriate sample containers as specified in
' the 6/00 NYSDEC ASP. The holding time criteria identified in Volume I for the individual
methods of the ASP will be followed, as specified in Table 1-1.
0 1314\A0314302.doc(R02) 1-14
Prior to packaging any samples for shipment, the sample containers will be checked for
' proper identification and compared to the field logbook for accuracy. The samples will then be
wrapped with a cushioning material and placed in a cooler (or laboratory shuttle) with a
' sufficient amount of bagged ice or "blue ice" packs in order to keep the samples at 4°C until
arrival at the laboratory.
All necessary documentation required to accompany the sample during shipment will be
placed in a sealed plastic bag and taped to the underside of the cooler lid. The cooler will then be
sealed with fiber (duct) tape, and custody seals will be placed in such a manner that any opening
of the cooler prior to arrival at the laboratory can be detected.
' All samples will be shipped to ensure laboratory receipt within 48 hours of sample
collection in accordance with NYSDEC requirements. The laboratory will be notified prior to the
' shipment of the samples.
' 1.6.3 Groundwater(Monitoring Well)
' 1. Be certain that the sample location is noted on Location Sketch (see Section 1.9).
' 2. Measure the depth of water using a decontaminated water level indicator and compute
the volume of standing water in the well.
3. Remove three to five times the volume of standing water from the well until field
measurements (pH, conductivity, temperature, and turbidity) stabilize, or until the
well is dry, whichever occurs first, with a submersible pump. (Turbidity must be less
than 50 NTUs prior to collection of a sample for metals analysis. Greater than
50 NTUs may require filtering of the sample or waiting a maximum of 24 hours for
the turbidity to decrease.)
4. Remove the laboratory precleaned sample containers from sample cooler, label
container with an indelible marker, fill out Sample Information Record and Chain of
' Custody Form(see Section 1.9).
5. Obtain a sample by using the disposable polyethylene bailer. The order to which the
samples are collected is: VOCs, metals, cyanide, and wet chemistry parameters.
♦1314\A0314302.doc(R02) 1-15
6. If the turbidity exceeds 50 NTUs, then the well should be sampled for all constituents
except metals. The well can rest for a maximum of 24 hours until a turbidity reading
is less than 50 NTUs, once less than 50 NTUs,the metals sample can be collected.
' 7. If it is determined in consultation with the NYSDEC that filtering of the sample is
necessary (i.e., through direction from NYSDEC or after waiting a maximum of
' 24 hours), first collect an unfiltered sample in a sample container, replace the cover
on the sample container and label the sample. Next, pour an appropriate amount of
the remaining sample from the bailer into a second sample container through a filter
' medium (0.45 microns) to remove particulates from suspension. Replace the cover on
the sample container and label the sample. The turbidity of both the filtered and
unfiltered sample will be recorded at the time of collection.
' 8. Gently pour the sample into the sample container taking care not to spill on outside of
bottle or overfill container and replace cover on the sample container. Samples for
volatile organic analyses, will have no air space in the sample vial prior to sealing.
This is done by filling the vial such that there is a meniscus on top. Carefully, slide
the septum, Teflon side down, onto the top of the vial and cap the vial. Check for
bubbles by turning the vial upside down and tapping it lightly. If bubbles appear,
reopen the vial, remove the septum and add more sample (or resample). Replace the
septum,recap and check for bubbles. Continue until vial is bubble-free.
' 9. Return sample container to sample cooler.
10. Dispose of bailer.
11. Place disposable personal protective equipment into a 55-gallon drum.
1.7 Decontamination Procedures
All field sampling equipment should be sterile and dedicated to a particular sampling
point. In instances where this is not possible, a field cleaning (decontamination) procedure will
be used in order to reduce the chances of cross contamination between sample locations. A
decontamination station will be established for all field activities. This will be an area located
away from the source of contamination so as not to adversely impact the decontamination
' procedure,but close enough to the sampling area to keep equipment handling to a minimum.
♦1314\AO314302.doc(R02) 1-16
a
1.7.1 Field Decontamination Procedures
All nondisposable equipment will be decontaminated at appropriate intervals (e.g., prior
to initial use, prior to moving to a new sampling location and prior to leaving the site). Different
decontamination procedures are used for various types of equipment that perform the field
activities as discussed below. When using field decontamination, it is advisable to start sampling
in the area of the site with the lowest contaminant probability and proceed through to the areas of
highest suspected contamination.
1.7.2 Decontamination Procedure for Drilling
All equipment such as drill rigs, backhoes and other mobile equipment should receive an
initial cleaning prior to use at the site. The equipment will then be decontaminated prior to
leaving the site and each time it returns on-site. Unless otherwise specified and approved, all
wash/rinse solutions should be collected and contained on-site. The actual fate of this material
will be determined after review of analytical data generated from samples and on-site discharge
impacts have been evaluated.
After the initial washing, cleaning may be reduced to those areas that are in close
proximity to materials being sampled. Drill rig items such as auger flights, drill rods, and drill
bits are to be cleaned in between sample locations.
All decontamination generated wastes will be contained in 55-gallon drums and stored in
the designated area.
Drilling equipment will be decontaminated in the following manner:
• Scrub all surfaces thoroughly with nonresidual nonionic anionic detergent (such as
alconox) and tap water using a brush to remove particulate matter or surface film.
This is necessary in order to remove any solids buildup on the back of the rig, auger
flights, drill rods, drilling head, etc. Any loose paint chips, paint flakes and rust must
also be removed.
♦1314\A0314302.doc(R02) 1-17
• Steam clean(212°F).
1.7.3 Decontamination Procedure for Sampling Equipment
Teflon, PVC, polyethylene, polystyrene and stainless steel sampling equipment
decontamination procedures will be the following:
• Wash thoroughly with nonresidual nonionic anionic detergent (such as alconox) and
clean potable tap water using a brush to remove particulate matter or surface film.
• Rinse thoroughly with tap water.
• Rinse thoroughly with distilled water.
• Rinse in a well ventilated area with methanol (pesticide grade) and air dry.
• Rinse thoroughly with distilled water and air dry.
• Wrap completely in clean aluminum foil with dull side against the equipment. For
small sampling items, such as scoops, decontamination will take place over a drum
specifically used for this purpose.
The first step, a soap and water wash, is to remove all visible particulate matter and
residual oils and grease. This is followed by a tap water rinse and a distilled/deionized water
rinse to remove the detergent. Next, a high purity solvent rinse is designated for trace organics
removal. Methanol has been chosen because it is not an analyte of concern in the TCL. The
solvent must be allowed to evaporate and then a final distilled/deionized water rinse is
performed. This rinse removes any residual traces of the solvent. The aluminum wrap protects
the equipment and keeps it clean until it is used at another sampling location.
1.7.4 Decontamination Procedure for Well Casing/
Screen and Development/Purging Equipment
Field cleaning of well casing and screen should consist of a manual scrubbing to remove
foreign material and steam cleaning, inside and out, until all traces of oil and grease are removed.
If precleaned certified well casing and screen can be obtained from the manufacturer this would
♦1314\A0314302.doc(R02) 1-18
also be acceptable. This material should then be stored in such a manner so as to preserve it in
this condition. Special attention to threaded joints may be necessary to remove cutting oil or
weld burn residues.
Materials and equipment that will be used within the monitoring well casing for the
purposes of well development and purging shall also be decontaminated.
The submersible pump will be decontaminated by the following procedures:
1. Place pump in a water solution of an nonionic anionic surfactant solution (such as
unscented Tide or Alconox) solution and wash the outside of the pump with a scrub
brush.
2. Pump approximately five gallons of the wash solution through the pump.
3. Place pump in bucket of clean water and pump out five gallons of water.
4. Wipe down the cable with deionized water and a paper towel.
5. Decontamination water will be disposed of on-site.
1.8 Laboratory Sample Custody Procedures
A NYSDOH ELAP and CLP certified laboratory meeting the requirements for sample
custody procedures, including cleaning and handling sample containers and analytical equipment
' will be used. The laboratory's Standard Operating Procedures (SOPs) will be available upon

request.
' 1.11 Performance of Field Audits
During field activities, the QA/QC officer may accompany sampling personnel into the
field to verify that the site sampling program is being properly implemented and to detect and
define problems so that corrective action can be taken. All findings will be documented and
provided to the Field Operations Manager. A copy of Field Audit form is in Section 1.23.
1.12 Control and Disposal of Contaminated Material
During sampling of the monitoring wells, water will be generated from purging.
Specifically, all water associated with the wells will be disposed of on-site. Decontamination
water will also be disposed of on-site.
1In general, soiled personal protective equipment (PPE) and disposable sampling
equipment (i.e., bailers, tongue depressors, scoops) will be considered solid waste and contained
and disposed off-site. If hazardous waste contamination of PPE or disposable equipment is
suspected, due to elevated measurements of screening instruments, visual observations, odors or
other means, PPE and equipment will be drummed and secured on-site until a hazardous waste
determination can be made. Once a determination has been made, an approved disposal method
will be employed.
1.13 Documentation,Data Reduction and Reporting
1 A NYSDOH ELAP and CLP certified laboratory meeting requirements for
documentation, data reduction, and reporting will be used. All data will be cataloged according
to sampling locations and sample identification nomenclature which is described in Section 1.6.1
of the QA/QC plan.
♦11 MAN 14302.doc(R02) 1-25
NYSDEC "Sample Identification and Analytical Requirement Summary" and "Sample
' Preparation and Analysis Summary" forms (for VOC Analysis, B/N-A Analysis, Pesticides/PCB

1.14 Data Validation
As described in Section 1.13 above, summary documentation regarding data validation
will be completed by the laboratory using NYSDEC forms contained in Section 1.22, and
submitted with the data package.
A Data Usability Summary Report (DUSR) will be prepared instead of full data
validation. The DUSR is prepared by reviewing and evaluating the analytical data. The
parameters to be evaluated in reference to compliance with analytical method protocols include
all chain-of-custody forms, holding times, raw data (instrument print out data and
chromatograms), calibrations, blanks, spikes, controls, surrogate recoveries, duplicates and
sample data. If available, field sampling notes should also be reviewed and any quality control
problems should be evaluated as to their effect on the usability of the sample data.
' The DUSR shall describe the samples and analysis parameters reviewed. Data
deficiencies, analytical protocol deviations and quality control problems shall be described and
their effect on the data discussed.
' Re-sampling and re-analysis recommendations will be made, if necessary. Data
qualifications are documented for each sample analyte following the NYSDEC ASP 6/00

♦1314\A0314302.doc(R02) 1_26
1.15 Performance and System Audits
A NYSDOH ELAP and CLP certified laboratory, which has satisfactorily completed
performance audits and performance evaluation samples shall be used.
1.16 Corrective Action
A NYSDOH ELAP and CLP certified laboratory shall meet the requirements for
corrective action protocols, including sample "clean up" to attempt to eliminate/mitigate "matrix
interference."
The 6/00 NYSDEC ASP protocols include both mandatory and optional sample cleanup
and extraction methods. Florisil column cleanup is required for the pesticide/PCB fraction of
both soil and water samples. There are several optional cleanup and extraction methods noted in
the 6/00 NYSDEC ASP protocol. These include: Silica gel column cleanup, acid-base partition,
steam distillation and sulfuric acid cleanup for PCB analysis.
It should be noted, that if these optional cleanup and extraction methods are requested by
' NYSDEC, holding time requirements should not be exceeded due to negligence of the
laboratory. However, subsequent to selection of the analytical laboratory for this project, a
' meeting will be scheduled among representatives of the NYSDEC, the Town and the laboratory
to discuss these issues and establish procedures to ensure good and timely communications
among all parties.
1.17 Trip Blanks (Travel Blanks)
The primary purpose of this type of blank is to detect additional sources of contamination
that might potentially influence contaminant values reported in actual samples both
quantitatively and qualitatively. The following have been identified as potential sources of
contamination:
♦1314W0314302.doc(R02) 1-27
' • Laboratory reagent water
• Sample containers
• Cross contamination in shipment
• Ambient air or contact with analytical instrumentation during preparation and
analysis at the laboratory
• Laboratory reagents used in analytical procedures
MA trip blank consists of a set of 40 ml sample vials filled at the laboratory with laboratory
demonstrated analyte free water. Trip blanks should be handled, transported and analyzed in the
same manner as the samples acquired that day, except that the sample containers themselves are
not opened in the field. Rather, they just travel with the sample cooler. Trip blanks must
accompany samples at a rate of one per shipment. The temperature of the trip blanks must be
maintained at 4°C while on-site and during shipment. Trip blanks must return to the laboratory
with the same set of bottles they accompanied in the field.
The purpose of a trip blank is to control sample bottle preparation and blank water quality
as well as sample handling. Thus, the trip blank travels to the site with the empty sample bottles
' and back from the site with the collected samples in an effort to simulate sample handling
conditions. Contaminated trip blanks may indicate inadequate bottle cleaning or blank water of
' questionable quality. Trip blanks are implemented only when collecting water samples, and
analyzed for volatile organic compounds only (i.e., baseline sampling).
r
1.18 Field Blank(Field Rinsate Blank)/Equipment Blank
Field blanks will not be required for this project, since disposable bailers are being
utilized for sample collection.
♦1314W0314302.doc(R02) 1-2.8
1.19 Matrix Spikes/Matrix Spike Duplicates and Spiked Blanks
Matrix spike (MS), matrix spike duplicates (MSD), and matrix spike blanks (MSB)
samples are quality control procedures, consistent with 6/00 NYSDEC ASP specifications, used
by the laboratory as part of its internal QA/QC program. The MS and MSD are aliquots of a
designated sample (water or soil), which are spiked with known quantities of specified
compounds. They are used to evaluate the matrix effect of the sample upon the analytical
methodology as well as to determine the precision of the analytical method used. A MSB is an
aliquot of analyte-free water, prepared in the laboratory, and spiked with the same solution used
to spike the MS and MSD. The MSB is subjected to the same analytical procedure as the
MS/MSD and used to indicate the appropriateness of the spiking solution by calculating the
spike compound recoveries. The procedure and frequency regarding the MS, MSD and MSB are
defined in the 6/00 NYSDEC ASP. Site specific MS and MSDs should be collected at a
frequency of one per 20 samples or every 7 days (one for each sample delivery group), for each
sample matrix collected (i.e., water, soil, etc.). The laboratory is required to analyze an MSB at
the same frequency as the MS/MSD.
1.20 Method Blanks
A method blank is an aliquot of laboratory water or soil, which is spiked with the same
internal and surrogate compounds as the samples. Its purpose is to define and determine the level
of laboratory background contamination. Frequency, procedure and maximum laboratory
containment concentration limits are specified in the 6/00 NYSDEC ASP as follows:
The laboratory shall prepare and analyze one laboratory reagent blank (method blank) for
each group of samples of a similar matrix (for water or soil samples), extracted by a similar
method (separatory funnel, continuous liquid extraction or sonication) and a similar
concentration level (for volatile and semivolatile soil samples only) for the following, whichever
is most frequent:

Currently, there are 16 monitoring wells at the Southold Landfill which are used to
onitor groundwater quality. These wells are grouped in pairs, with one well being shallow and
mcreened across the water table, and the other well being screened deep just above the clay unit
Ghat underlies the landfill, with the exception of S-68916, which is screened below the water
table at 103 feet, and S-68831, which is screened below the clay unit at 190 feet. Depending on
I
location and ground surface elevation, the water table wells vary in depth from 27 to 77 feet 1
below ground surface (bgs) with the average depth being approximately 55 feet, and the deep
wells (exclusive of S-68831) vary in depth from 85 feet to 150 feet bgs with the average depth
ry being about 130 feet. The locations of these wells are shown on Drawing 2.
The existing monitoring wells are constructed with 2-inch diameter PVC casing and
stainless steel screens with locking steel protective surface casings. Screen lengths for the
shallow wells are 20 feet, and screen lengths for the deep wells are 10 feet. These wells,
exclusive of S-68831 and S-68916, are constructed in accordance with Part 360 requirements.
(S-68831 and S-68916 were constructed by the Suffolk County Department of Health Services in
the early 1980s and the construction details are not known.)
As part of closure construction, ten groundwater monitoring wells at five locations will
need to be abandoned since they are located in areas that will be graded and capped or where
maintenance access roads are planned to be constructed. These wells are MW-2S and 2D; MW-
3S and 3D; MW-6S and 6D; MW-7S and 7D; and S-68831 and S-68916. Well abandonment
will be in accordance-with Part 360 procedures contained in 360-2.11(a)(8)(vi). After the cap
and maintenance roads are constructed, six of the ten monitoring wells will be replaced with new
wells at approximately the same locations as the abandoned wells and constructed in accordance
with Part 360-2.11(a)(8).
i
Monitoring wells MW-2S and 2D will not be replaced since well clusters MW-4 and
MW-5 will effectively monitor groundwater quality downgradient of the MW-2 cluster, and
♦1314\G0820801.DOC(R02) 9-1
monitoring wells MW-7S and 7D will not be replaced since they are located upgradient of the
area of waste and historically have shown little/background contamination. Locations of the
replacement wells are shown on Drawing 3.
l
Each new groundwater monitoring well will be constructed in a drilled borehole
approximately 8 inches in diameter. Drilling will be performed with hollow stem augers. The
wells will be constructed of a 2-inch diameter Schedule 304 stainless steel screen and threaded,
flush joint Schedule 40 PVC casing. Ten feet of stainless steel wire wrapped screen with 0.02-
inch openings will be installed in each deep borehole, and 20-foot screens will be installed in
each shallow borehole, 5 feet above the water table and 15 feet below. The PVC riser will
extend from the top of the screen to 21/2 feet above ground surface and will be contained in a steel
protective casing with a locking cover.
The annulus of the borehole in the area of the screen will be sand-packed to a height of 2
feet above the screened interval with No. 1 Grade clean silica sand. A finer grained No. 00 sand
pack material (100 percent passing the No. 30 sieve and less than 2 percent passing the No. 200
sieve), 6 inches in thickness, will be placed on top of the sand pack between the sand and the
bentonite seal. A 3-foot seal of bentonite pellets or slurry will be placed immediately above the
filter material and 6 inches of No. 00 Grade silica sand pack will be placed above the bentonite
seal. The remaining annulus will be grouted to the surface with cement/bentonite grout. The
bentonite will be tested and/or warranteed to be free or organic and inorganic contaminants. All
material placed in the annulus of the borehole will be installed using a tremie pipe.
A 4-inch diameter protective outer steel surface casing with locking cover and a surface
cement pad will be installed around each well casing/riser. An illustration of well construction is
provided on Drawing 6.
