SITE MANAGEMENT PLAN
1.0 INTRODUCTION AND DESCRIPTION OF REMEDIAL PROGRAM
1.1 INTRODUCTION
This document is required as an element of the remedial program at Sharon Cleaners
(hereinafter referred to as the “Site”) under the New York State (NYS) Inactive Hazardous
Waste Disposal Site Remedial Program administered by New York State Department of
Environmental Conservation (NYSDEC). The site was remediated in accordance with State
Superfund Program, Site # 546052.
1.1.1 General
The NYSDEC conducted remedial activities detailed in the Record of Decision (ROD),
dated March 2009, at the site located in the City of Saratoga Springs, New York. A figure
showing the site location and boundaries of this “site” is provided in Figure 1. The boundaries of
the site are more fully described in the metes and bounds site description that is part of the
Environmental Easement, which is included in Appendix A.
After completion of the remedial work described in the ROD, some contamination was
left in the subsurface at this site, which is hereafter referred to as “remaining contamination.”
This Site Management Plan (SMP) was prepared to manage remaining contamination at the site
until the Environmental Easement is extinguished in accordance with ECL Article 71, Title 36.
All reports associated with the site can be viewed by contacting the NYSDEC or its successor
agency managing environmental issues in New York State.
This SMP was prepared by NYSDEC, in accordance with the requirements in NYSDEC
DER-10 Technical Guidance for Site Investigation and Remediation, dated November 2009.
This SMP addresses the means for implementing the Institutional Controls (ICs) and Engineering
Controls (ECs) that are required by the Environmental Easement for the site.
Sharon Cleaners (546052) Site Management Plan

1.1.2 Purpose
The site contains contamination left after completion of the remedial action. Engineering
Controls have been incorporated into the site remedy to control exposure to remaining
contamination during the use of the site to ensure protection of public health and the
environment. An Environmental Easement granted to the NYSDEC, and recorded with the
Saratoga County Clerk, requires compliance with this SMP and all ECs and ICs placed on the
site. The ICs place restrictions on site use, and mandate operation, maintenance, monitoring and
reporting measures for all ECs and ICs. This SMP specifies the methods necessary to ensure
compliance with all ECs and ICs required by the Environmental Easement for contamination that
remains at the site. This plan has been approved by the NYSDEC, and compliance with this plan
is required by the grantor of the Environmental Easement and the grantor’s successors and
assigns. This SMP may only be revised with the approval of the NYSDEC.
This SMP provides a detailed description of all procedures required to manage remaining
contamination at the site after completion of the Remedial Action, including: (1) implementation
and management of all Engineering and Institutional Controls; (2) media monitoring; (3)
operation and maintenance of all vapor mitigation systems; and (4) performance of periodic
inspections, certification of results, and submittal of Periodic Review Reports.
To address these needs, this SMP includes three plans: (1) an Engineering and
Institutional Control Plan for implementation and management of EC/ICs; (2) a Monitoring Plan
for implementation of Site Monitoring; (3) an Operation and Maintenance Plan for
implementation of vapor mitigation systems.
This plan also includes a description of Periodic Review Reports for the periodic
submittal of data, information, recommendations, and certifications to NYSDEC.
It is important to note that:
• This SMP details the site-specific implementation procedures that are required by the
Environmental Easement. Failure to properly implement the SMP is a violation of
the environmental easement;
• Failure to comply with this SMP is also a violation of Environmental Conservation
Law, 6NYCRR Part 375 for the site, and thereby subject to applicable penalties.
1.1.3 Revisions
Revisions to this plan will be approved by the NYSDEC’s project manager.

1.2 SITE BACKGROUND
1.2.1 Site Location and Description
The Sharon Cleaners site is located 48 Lincoln Avenue in the City of Saratoga Springs,
New York and is identified as Section 165.82 Block 2 and Lot 34.1, See Figure 1, Site Location
Plan. The site covers 0.17 acres and is located at the southeast corner of the intersection of
Lincoln Avenue and Whitney Place. A one-story structure that covers approximately 2,200
square feet is located at the site and presently occupied by AJ's Wash and Dry Cleaners. The
surrounding area is mixed commercial and residential. The nearest residential structure is
located approximately 25 feet to the east.
1.2.2 Site History
The site has been used as a dry cleaning business for over 50 years. During this time
Sharon Cleaners was in operation for approximately 22 years. In conducting a site audit for use
in selling the property, the site owner discovered chlorinated volatile organic compounds,
primarily tetrachloroethene (PCE), in the soil and groundwater in February 2000. Dry cleaning
and spot removal processes are believed to have utilized PCE, which is a typical chemical used
in the dry cleaning industry. Improper housekeeping is likely the cause of the environmental
impacts.
In 2001 the current owner operated dry cleaning operations at the site under AJs Wash
and Dry Cleaning. Presently the property is being leased by the owner. Current dry cleaning
equipment utilizes a petroleum based dry cleaning agent, DF2000, which is different from the
chlorinated volatile organic compounds detected in the environment.
1.3 SUMMARY OF REMEDIAL INVESTIGATIONS
Site investigations were performed to characterize the nature and extent of contamination
at the site by collecting soil, groundwater and soil vapor samples. As seen in Figures 3 and 4 or
summarized in Table 1, the main category of site related contaminants that exceed their SCGs
are volatile organic compounds (VOCs). The following are the media which were investigated
and a summary of the findings of the investigation.
Sharon Cleaners (546052) Site Management Plan

Surface Soil
Seven surface soil samples were collected at the site from 0 to 12 inches below ground
surface and analyzed for VOCs. These samples were located in the grassy areas at the north and
south portions of the site. Figure 2 presents the analytical results and locations of the soil
samples. Based on the analytical results PCE was detected up to 0.055 parts per million (ppm),
which is below the unrestricted use cleanup objective of 1.3 ppm. Elevated concentrations of
metals were detected in the surface soils above unrestricted use at the site, as shown on Figure 3.
Due to the sporadic detections of these metals, the contamination is considered to be
representative of background conditions from fill material placed at the site and not a result of
the dry cleaning activities conducted at the site since metals are not utilized as part of the dry
cleaning process.
Subsurface Soil
Nineteen subsurface soil samples were collected at the site and analyzed for VOCs.
Thirteen soil borings, identified as B-1 through B-13, were completed to assess site soil
conditions south and north of the facility. One soil sample was collected from each boring at
depths ranging from 10 to 16 feet below ground surface based on visual observations or depth to
groundwater. One shallow soil sample, 1 to 2 feet below ground surface, was collected beneath
the pavement, identified as SS-1. Five sub-slab soil samples, identified as SS-6 through SS-10,
were collected from 0 to 12 inches beneath the concrete slab in the vicinity of the dry cleaning
equipment and former trench. Figure 2 presents the analytical results and locations of the soil
samples. Based on the analytical results PCE was detected up to 0.170 ppm beneath the structure
and up to 0.029 ppm beyond the buildings footprint, which are below the unrestricted use
cleanup objective of 1.3 ppm. The greatest concentration of PCE was detected at 1.6 ppm
beneath the concrete slab during the site characterization in 2006. PCE detections are minimal
due to discontinued use of PCE at the dry cleaning facility, operation of the soil vapor extraction
system under the Voluntary Cleanup Program and natural attenuation of site contaminants over
time.
Elevated concentrations of metals were detected in the shallow subsurface soils above
unrestricted use at the site, as shown on Figure 2. Due to the sporadic detections of these metals,
the contamination is considered to be representative of background conditions from fill material
placed at the site and not a result of the dry cleaning activities conducted at the site since metals
are not utilized as part of the dry cleaning process.
Sharon Cleaners (546052) Site Management Plan

Groundwater
Twelve groundwater samples were collected and analyzed for VOCs. These samples
were collected from ten monitoring wells and two temporary wells located within 30 feet of
ground surface. Six samples were collected at the site and six samples were collected from off-
site locations that are considered either up-gradient, down-gradient or side gradient. Figure 3
presents the analytical results and locations of the groundwater samples. Based on the analytical
results PCE was detected up to 24 parts per billion (ppb) at MW-11, which is above the
groundwater standard of 5 ppb. The low level contamination appears to be originating from the
site and naturally attenuates within 400 feet of the site.
Soil Vapor/Sub-Slab Vapor/Air
Ten structures in the vicinity of the site were evaluated to assess the soil vapor intrusion
pathway. An indoor air sample and a sub-slab vapor samples were collected from each structure
and analyzed for VOCs. Analytical results were compared to ambient air levels, building
questionnaires, and reported background values for residential structures. Based on the
analytical results PCE was detected within the indoor air samples at concentrations up to 7.3
micrograms per cubic meter (ug/m3). New York State Department of Health PCE factsheet,
dated May 2003, indicates that typical background concentrations of PCE in residential homes
are less than 10 ug/m3. Elevated PCE concentrations were detected in sub-slab soil vapor on-
site, identified as structure 9, up to 23,000 ug/m3, and at four off-site structures, identified as
structures 1, 7, 8, and 10, up to 5,000 ug/m3. Soil vapors impacting sub-slab vapor
concentrations appear to be a result of site contamination that emanated from the site or off-
gased from groundwater.
The results of the investigations are described in detail in the following reports:
• Remediation Report, dated May 10, 2001, details initial investigations conducted in February and
March 2000 and the Volunteer’s unilaterally installation and operation of a soil vapor extraction
system.
• Site Characterization Report, dated February 2007, details State-funded investigations conducted
in September 2006.
• Remedial Investigation Report, dated February 2009, details State-funded investigations
conducted in April 2008.
• Record of Decision, dated March 2009, summarizing findings and selected action.

2. An environmental easement will be filed with the County Clerk that (a) restricts the
use of groundwater as a source of potable or process water, without necessary water
quality treatment as determined by NYSDOH; and (b) the site property owner will
complete and submit to the NYSDEC a periodic certification of institutional and
engineering controls. The executed environmental easement shall be included in this
plan as Appendix A.
3. This site management plan details the actions to be completed for the following
institutional and engineering controls: (a) monitoring of sub-slab soil vapor and
indoor concentrations at two additional structures, identified as AS-1 and AS-10,
which had levels that did not warrant mitigation will be monitored for a minimum of
three years; and (b) provisions for the continued proper operation and maintenance
of the components of the remedy.
4. The site property owner will provide a periodic certification of institutional and
engineering controls. This submittal will: (a) contain certification that the
institutional controls and engineering controls put in place are still in place and are
either unchanged from the previous certification or are compliant with NYSDEC-
approved modifications; (b) allow the NYSDEC access to the site; and (c) state that
nothing has occurred that would impair the ability of the control to protect public

2.0 ENGINEERING AND INSTITUTIONAL CONTROL PLAN
2.1 INTRODUCTION
Since remaining contaminated groundwater and soil vapor exists beneath the site,
Engineering Controls and Institutional Controls (EC/ICs) are required to protect human health
and the environment. This Engineering and Institutional Control Plan describes the procedures
for the implementation and management of all EC/ICs at the site. The EC/IC Plan is one
component of the SMP and is subject to revision by NYSDEC.
2.2 ENGINEERING CONTROLS
2.2.1 Engineering Control Systems
Exposure to remaining contamination in soil vapor is prevented by continued operation of
the vapor mitigation systems installed at the site and two off-site structures. Details of the
systems are provided in Appendix B. Procedures for the inspection and maintenance of these
systems are provided in the Operation and Maintenance Plan (Section 4 of this SMP).
2.2.2 Criteria for Completion of Remediation/Termination of Remedial/Mitigation Systems
The on-site Vapor Mitigation system will not be discontinued unless prior written
approval is granted by the NYSDEC following consultation with NYSDOH.
2.3 INSTITUTIONAL CONTROLS
A series of Institutional Controls is required by the ROD to: (1) implement, maintain and
monitor Engineering Control systems; and (2) prevent future exposure to contamination by
restricting groundwater use. Adherence to these Institutional Controls on the site is required by
the Environmental Easement and will be implemented under this Site Management Plan.
Institutional Controls identified in the Environmental Easement may not be discontinued without
an amendment to or extinguishment of the Environmental Easement.

The site has a series of Institutional Controls in the form of site restrictions. Adherence to
these Institutional Controls is required by the Environmental Easement. Site restrictions that
apply to this site are:
• The use of the groundwater underlying the property as a source of potable or process
water, without necessary water quality treatment as determined by NYSDOH, is
prohibited; and
• The site owner or remedial party will submit to NYSDEC a written statement that
certifies, under penalty of perjury, that: (1) controls employed at the controlled
property are unchanged from the previous certification or that any changes to the
controls were approved by the NYSDEC; and, (2) nothing has occurred that impairs
the ability of the controls to protect public health and environment or that constitute a
violation or failure to comply with the SMP. NYSDEC retains the right to access
such Controlled Property at any time in order to evaluate the continued maintenance
of any and all controls. This certification shall be submitted annually, or an alternate
period of time that NYSDEC may allow, and will be made by an individual that the
NYSDEC finds acceptable.

3.0 SITE MONITORING PLAN
3.1 INTRODUCTION
The Monitoring Plan describes the measures for evaluating the performance and
effectiveness of the remedy to reduce or mitigate contamination at the site and all affected site
media. Monitoring of Engineering Controls is described in Section 4, Operation, Monitoring and
Maintenance Plan. This Monitoring Plan may only be revised with the approval of NYSDEC.
3.2 AIR MONITORING PROGRAM
Indoor air and sub-slab soil vapor monitoring will be performed annually during the
heating season by NYSDEC for three years to assess conditions at two off-site structures,
identified as AS-1 and AS-10. The frequency thereafter will be determined by NYSDEC.
All monitoring activities will be recorded in the building inventory and sample form in
Appendix C. An indoor air and sub-slab soil vapor sample shall be collected over a 24 hour
period utilizing 6-liter individually certified clean summa canisters. Samples shall be analyzed
by an ELAP certified laboratory for volatile organic compounds following EPA method TO-15,
reporting limits of 1 microgram per cubic meter. A Data Usability Summary Report (DUSR)
shall be prepared in accordance with DER-10 procedures. A duplicate sample and an ambient air
sample shall be collected. Laboratory or food grade Teflon tubing shall be utilized to connect
sub-slab soil vapor points with canisters and to facilitate purging 1-3 volumes prior to sampling.
A chain of custody shall be completed by the sampler and submitted with the samples to the
laboratory. Sampling procedures shall be conducted in accordance with NYSDOH Guidance for
Evaluating Soil Vapor Intrusion in the State of New York. Deliverables for the structure
monitoring program are specified in Section 3.4.
3.3 MONITORING WELL DECOMMISSIONING
When determined appropriate, ten monitoring wells, identified as MW-4 through MW-11
and SVE-1 and SVE-2, will be properly decommissioned by NYSDEC in accordance with
Groundwater Monitoring Well Decommissioning Policy CP-43. The monitoring well locations
are illustrated on Figure 4 and construction details are provided in Appendix D. The
Sharon Cleaners (546052) Site Management Plan
12
flushmounts shall be removed to facilitate reseeding. Grouting in place is the anticipated
decommission method. A standard grout mixture shall be used (94 pounds of Type I Portland
cement, 3.9 pounds powdered bentonite, and 7.8 gallons potable water). CP-43 well
decommissioning records shall be prepared for each monitoring well, Appendix E.
3.4 MONITORING REPORTING REQUIREMENTS
After each sampling event a letter report shall be prepared that summarizes field work
performed and provides laboratory data sheets and field forms. Data will be reported in
hardcopy and digital format.

4.0 OPERATION AND MAINTENANCE PLAN
4.1 INTRODUCTION
This Operation and Maintenance Plan describes the measures necessary to operate,
monitor and maintain the mechanical components of the remedy selected for the site. A copy of
this Operation and Maintenance Plan, along with the complete SMP, will be kept at the site.
This Operation and Maintenance Plan is not to be used as a stand-alone document, but as a
component document of the SMP.
4.2 ENGINEERING CONTROL SYSTEM OPERATION, MAINTENANCE AND
MONITORING
Vapor mitigation systems were installed in November 2009 to provide a preferential
pathway for soil vapors to move from beneath the building to the outside. System installation
reports are included as Appendix B, which details the construction and performance of the
systems after installation and monitoring activities. These are low maintenance systems and as a
result the property owners are responsible for supplying power and monitoring the systems, once
every three months, and contacting the NYSDEC project manager when a problem arises (i.e.
fan off/noisy or manometer levels are equal). When the NYSDEC is contacted by the owner, a
NYSDEC contractor will be retained to maintain the system and a Maintenance Request Form
(Appendix F) will be completed. During system maintenance, and periodic reviews, the Periodic
Operations Visit Form will be completed (Appendix G). Maintenance reports and any other
information generated during regular operations at the site will be submitted as part of the
Periodic Review Report, as specified in the Section 5 of this SMP. Vapor mitigation system
testing may be necessary if significant changes are made to the system (i.e. replace fan or move
extraction point).

1.0 Introduction
During October and November of 2009 Aztech Technologies (Aztech) installed a passive sub-slab
depressurization system, and reconstructed portions of the existing concrete slab at 50 Lincoln Avenue in
Saratoga Springs, NY. The sub-slab depressurization system was installed in order to mitigate the
intrusion of soil vapors into the structure. The work included the demolition of the existing slab; installation
of a new four-inch thick, reinforced concrete slab; and the installation of the sub-slab depressurization
well and effluent piping.
2.0 Construction and System Overview
2.1 Demolition and Reconstruction
Kodiak Construction of Saratoga Springs was contracted by Aztech Technologies to complete the
demolition and reconstruction work. A building permit was secured for the project prior to any work
commencing. A pre-construction video survey and post-construction video survey was completed by
Patricia Billings Consulting Services to ensure that the condition of the property was not adversely
affected by the construction activities. All copies of the surveys are held by Patricia Billings Consulting
Services.
A stamped set of drawings produced by Kodiak Construction provided the guidance for the workers to
temporarily brace the existing structure while installing new footings and lolly columns prior to the
concrete slab being poured. Approximately 2000 pounds of native material and concrete debris were
removed from the basement by hand in order to provide a sufficient area for the sub-base material to be
installed.
The sub-base consisted of two-inches of number-one stone and a layer of Delta MS underlayment. This
provided a preferential pathway for the soil vapors to escape through the system as discussed in section
2.2. The underlayment was sealed at the joints using adhesive tape. Upon completion of the slab finish
work, the voids between the slab and the walls were caulked using Sonolastic NP1 polyurethane joint
sealant and the expansion joints were also sealed using NP1 (see Appendix I).
2.2 Sub-Slab Depressurization Well Installation
The concrete slab was cored using a core drill with a six-inch core barrel. The sub-base material and
native material below the slab was excavated to a depth of approximately eighteen-inches and a thin
layer of pea-gravel was installed at the bottom of the excavation. The sub-slab depressurization well was
constructed of an eighteen-inch length of four-inch, schedule 40 polyvinylchloride (PVC) pipe that was
perforated and inserted to the bottom of the hole. Pea gravel was inserted into the annular space as a
packing material up to the bottom of the four-inch slab. A four-inch schedule 40 PVC coupling was glued
on to the top of the well and the remaining annular space was sealed using hydraulic cement.
2.3 System Piping
The system piping was run from the well to the western foundation wall and then to the floor joists and out
of the basement through a 4.5” diameter hole cut by Aztech Technologies. The penetration was sealed
using clear silicone caulk. From the wall penetration the piping runs up the side of the house and
terminates above the roof line ten feet from any opening and a minimum of three feet from the eaves.
Aztech color matched two exterior paints to the existing trim colors and painted the effluent pipe for
aesthetic purposes.
Aztech Technologies, Inc. Page 2
3.0 Maintenance and Inspection of the System
The sub-slab depressurization system is passive and requires no power source. It operates by providing
a preferential pathway for soil vapors to escape from beneath the basement slab.
The system requires minimal maintenance; as such, the NYSDEC will respond to requests for service.
The primary means for evaluating system operation is through inspection by the property owner. Periodic
assessments are suggested (approximately every 3 months) to verify that the system piping and seals
are tight.
If a problem is identified, contact the NYSDEC Project Manager, Mr. Brian Jankauskas at 518-402-9620
and reference Site Number: 546052.
Audits will be performed by the NYSDEC to evaluate performance of the system. Audits may include:
• Inspection of the well to verify a proper seal
• Inspection of piping and vent stacks for cracks and leaks
• Collection of air samples
