prepared by Roux Associates, Inc.
Roux Associates performed the following scope of work during the investigation of the Site:
1. Conducted a Site inspection to identify AOCs and physical obstructions (i.e. structures, buildings, etc.);
2. Installed and sampled three temporary sub-slab soil vapor probes on October 31, 2016;
D R A F T Hazardous Materials Remedial Action Plan
Inwood Charter School OER Project # 17TMP0187M
REMEDIAL ENGINEERING, P.C. – 3 – 2842.0001Y.103R/RAP
3. Installed six soil borings, and collected twelve soil samples for analysis on November 21, 2016; and
4. Installed and sampled five temporary soil vapor probes between November 21 and November 22, 2016.
Roux Associates provided a brief summary of the soil vapor sampling analytical results to
OER. In an email dated December 8, 2016, OER requested three additional soil vapor samples
to be collected to refine the delineation of the nature and extent of an elevated detection of
tetrachloroethene (PCE) in soil vapor sample SV-2 (Figure 4), including the re-sampling of soil
vapor sample location SV-2.
On December 14, 2016, Roux Associates re-mobilized to the Site to collected the additional
soil vapor samples, the re-sample of SV-2, and additional soil samples associated with the new
soil vapor samples. Since SV-2 was a temporary soil vapor sampling point, a new sampling
point was installed in the auto-repair shop within 5 feet of SV-2. Roux Associates performed the
following scope of work during the re-mobilization:
1. Installed four soil borings and collected 4 soil samples for analysis; and
2. Installed and sampled four temporary soil vapor probes.
Roux Associates, Inc. provided a brief summary of the soil and soil vapor sampling
analytical results to OER. During a February 3, 2017 conference call, OER requested two
additional soil vapor samples be collected to determine whether or not off-site soil vapor
migration was occurring.
On February 14, 2017, Roux Associates re-mobilized to the Site to collect the additional soil
vapor samples.
1.5 Geophysical Investigation
On November 22, 2016, NAEVA Geophysics conducted a geophysical investigation at the
Site. The geophysical investigation, consisting of electromagnetic (EM) and ground penetrating
D R A F T Hazardous Materials Remedial Action Plan

REMEDIAL ENGINEERING, P.C. – 4 – 2842.0001Y.103R/RAP
radar (GPR), was performed to evaluate portions of the property for the potential presence of
underground storage tanks (USTs) or other subsurface structures associated with the building.
The area of the investigation was the indoor offices of the parking garage, plus an approximate
10-foot radius around the offices (including the sidewalk along 10th Avenue). The geophysical
survey results did not provide any conclusive evidence for a UST in the areas investigated.
However, an unknown GPR anomaly located on the west/southwest side of the offices was large
enough to potentially represent one or more USTs, and it is located in the area where an assumed
suspected vent line terminates. The geophysical report is provided in Appendix X of the RIR.
Digital (PDF) copies of the above referenced environmental work plans and reports are
included as Appendix B.
1.6 Summary of Regulatory Correspondence
There were no regulatory correspondence related to the Site:
1.7 Findings of Environmental Investigation
1. Elevation of the property above mean sea level is approximately 16 feet.
2. Groundwater was not encountered in unconsolidated material (fill) beneath the Site building.
3. Depth to bedrock is ranged from 5 to 7 feet at the Site.
4. Two distinct geologic strata were encountered at the Site from land surface to a maximum depth of 8 feet. These strata include from land surface downward:
a. Overburden material consisting of sand and gravel with traces of silt and weathered bedrock was present throughout the Site with a thickness that ranged from 0.5 to 8 feet.
b. Weathered bedrock was encountered between the overburden and more competent bedrock. The only boring that did not display this trend in lithology was RSB-6.
c. Bedrock was encountered throughout the site at depths ranging from 6 to 8 feet below the top of the building slab.

REMEDIAL ENGINEERING, P.C. – 5 – 2842.0001Y.103R/RAP
5. Sixteen soil samples and one duplicate sample were collected from 10 borings during the RI at the Site. There were no detections of volatile organic compounds (VOCs), semi-volatile organic compounds (SVOCs), metals, polychlorinated biphenyls (PCBs), or pesticides in soil at concentrations above the NYSDEC Subpart 375-6 Unrestricted Use Soil Cleanup Objectives. Soil sample analytical results are presented in Tables 1 through 5.
6. The summary of detections of VOCs in soil vapor below was focused on petroleum-related and chlorinated VOCs that are typically indicative of sub-surface impacts to soil and groundwater. Soil vapor analytical results are presented in Table 6, and on Figure 4.

Inwood Charter School OER Project # 17TMP0187M
REMEDIAL ENGINEERING, P.C. – 6 – 2842.0001Y.103R/RAP
Of the chlorinated VOCs detected, both trichloroethene (TCE) and tetrachloroethene (PCE) were detected at concentrations in soil vapor that require monitoring1. PCE was detected at three locations (SV-2, SV-6 and SV-9) at concentrations that require mitigation (1,260 to 2,280 micrograms per cubic meter).
There was no evidence that offsite migration of VOCs in soil vapor was occurring toward adjacent buildings and properties.
For environmental investigation data, consult reports listed in Section 1.4. Based on an
evaluation of the environmental data and information, disposal of significant amounts of
hazardous waste is not expected at this site.

REMEDIAL ENGINEERING, P.C. – 7 – 2842.0001Y.103R/RAP
2.0 DESCRIPTION OF REMEDIATION
2.1 Objectives
The Site remediation and mitigation objectives are:
Soil
Prevent direct contact with contaminated soil.
Prevent exposure to contaminants volatilizing from contaminated soil.
Prevent migration of contaminants that would result in groundwater or surface water contamination.
Soil Vapor
Prevent exposure to contaminants in soil vapor.
Prevent migration of soil vapor into dwelling and other occupied structures.
Remedial and mitigation measures described herein will be performed in accordance with
applicable laws and regulations, and the site-specific CHASP. This remedy is protective of
public health and/or the environment for the intended use.
2.2 Summary of Remedial Action
The proposed plan achieves all of the remedial action goals established for the project.
The proposed remedial action is effective in both the short-term and long-term and reduces
mobility, toxicity and volume of contaminants and uses standard methods that are well
established in the industry.
1. Removal of underground storage tanks (if encountered) and closure of petroleum spills in compliance with applicable local, State and Federal laws and regulations.
2. Construction and maintenance of an engineered composite cover consisting of the existing building floor slab, or a new slab, if determined to be necessary for the future use of the Site as a school to prevent human exposure to residual soil/fill remaining under the Site.
D R A F T Hazardous Materials Remedial Action Plan
Inwood Charter School OER Project # 17TMP0187M
REMEDIAL ENGINEERING, P.C. – 8 – 2842.0001Y.103R/RAP
3. Installation and operation of an active sub-slab depressurization system.
4. Screening of excavated soil/fill during intrusive work for indications of contamination by visual means, odor, and monitoring with a PID.
5. Performance of all activities required for the remedial action, including permitting requirements, in compliance with applicable laws and regulations.
6. Submission of a Remedial Closure Report (RCR) that describes the remedial activities, certifies that the remedial requirements have been achieved, and describes all Engineering and Institutional Controls to be implemented at the Site, and lists any changes from this RAP.
2.3 Soil Cleanup Objectives and Soil/Fill Management
No soil was encountered beneath the Site that contained constituents at concentrations
above unrestricted residential Soil Cleanup Objectives (SCOs). Therefore, no impacted soil
management will be necessary for any small excavation activities (e.g., excavation of elevator
pits) for this project.
In the unlikely event that discrete contaminant sources (such as hotspots) are identified
during the remedial action, they will be horizontally and vertically identified by GPS or
surveyed. This information will be provided in the RCR.
Soil cleanup objectives (SCOs) for soil at BCP sites are the numerical soil cleanup objectives
presented in 6NYCRR Sub-part 375-6.
Based upon the evaluation of the current soil data discussed in the RI and the proposed future
use of the Site, the SCOs for soil are the NYSDEC Subpart 375-6 Unrestricted Use SCOs.
2.4 Engineering Controls
Engineering Controls will be employed in the remedial action to address residual
contamination remaining at the site. The Site will have two primary Engineering Control (EC)
Systems. These are:
D R A F T Hazardous Materials Remedial Action Plan
Inwood Charter School OER Project # 17TMP0187M
REMEDIAL ENGINEERING, P.C. – 9 – 2842.0001Y.103R/RAP
composite cover system consisting of asphalt covered roads, concrete covered sidewalks, and concrete building slabs; and
active sub-slab depressurization system.
A conceptual layout and details of the proposed SSDS is provided on Figure 5. Details
regarding the final SSDS construction and layout will be provided in a separate design report
once the interior configuration of the proposed Charter School is finalized.
Composite Cover System
Exposure to residual soil/fill will be prevented by an engineered, composite cover system to
be built on the Site. This composite cover system is comprised of:
the existing concrete building slab2.
Figure 5 shows the typical cross-section for the composite cover system to be used on this
Site.
The composite cover system is a permanent engineering control for the Site.
2 Development plans indicate that a new building slab may have to be installed. In that event, a vapor barrier may be included as an engineering control.

3.0 REMEDIAL ACTION MANAGEMENT
3.1 Project Organization and Oversight
The Professional Engineer (PE) and Qualified Environmental Professionals (QEP) for this
project are Nathan Epler, Ph.D. and Glenn Netuschil, P.E.
3.2 Site Security
Site access will be controlled by restricting access through the existing entrances to the
building using traffic cones, and/or security personnel.
3.3 Work Hours
The hours for operation of remedial construction will be from 7:00 AM to 6 PM on
weekdays. These hours conform to the New York City Department of Buildings construction
code requirements.
3.4 Construction Health and Safety Plan
The site-specific Construction Health and Safety Plan (CHASP) is included in Appendix A.
The Site Safety Coordinator will be Joseph Gavin. Remedial work performed under this RAP
will be in full compliance with applicable health and safety laws and regulations, including Site
and OSHA worker safety requirements and HAZWOPER requirements. Confined space entry, if
any, will comply with OSHA requirements and industry standards and will address potential
risks. The parties performing the remedial construction work will ensure that performance of
work is in compliance with the CHASP and applicable laws and regulations. The CHASP
pertains to remedial and invasive work performed at the Site until the issuance of the Notice of
Satisfaction.
All field personnel involved in remedial activities will participate in training required under
29 CFR 1910.120, including 40-hour hazardous waste operator training and annual 8-hour
D R A F T Hazardous Materials Remedial Action Plan

REMEDIAL ENGINEERING, P.C. – 11 – 2842.0001Y.103R/RAP
refresher training. Site Safety Officer will be responsible for maintaining workers training
records.
Personnel entering any exclusion zone will be trained in the provisions of the CHASP and
be required to sign an CHASP acknowledgment. Site-specific training will be provided to field
personnel. Additional safety training may be added depending on the tasks performed.
Emergency telephone numbers will be posted at the site location before any remedial work
begins. A safety meeting will be conducted before each shift begins. Topics to be discussed
include task hazards and protective measures (physical, chemical, environmental); emergency
procedures; PPE levels and other relevant safety topics. Meetings will be documented in a log
book or specific form.
An emergency contact sheet with names and phone numbers is included in the CHASP.
That document will define the specific project contacts for use in case of emergency.
3.5 Community Air Monitoring Plan
No impacted soil was encountered during the Remedial Investigation. All intrusive work
(e.g., installation of the SSDS) will occur within the building. Therefore, real-time air
monitoring for volatile organic compounds (VOCs) and particulate levels at the perimeter of the
exclusion zone or work area will not be necessary.
3.6 Agency Approvals
All permits or government approvals required for remediation and construction will be
obtained prior to the start of remediation and construction. Acceptance of this RAP by OER
does not constitute satisfaction of these requirements and will not be a substitute for any required
permit.

REMEDIAL ENGINEERING, P.C. – 12 – 2842.0001Y.103R/RAP
3.7 Site Preparation
Pre-Construction Meeting
OER will be invited to attend the pre-construction meeting at the Site with all parties
involved in the remedial process prior to the start of remedial construction activities.
Mobilization
Mobilization will be conducted as necessary for each phase of work at the Site.
Mobilization includes field personnel orientation, equipment mobilization (including securing all
sampling equipment needed for the field investigation), marking/staking sampling locations and
utility mark-outs. Each field team member will attend an orientation meeting to become familiar
with the general operation of the Site, health and safety requirements, and field procedures.
Utility Marker Layouts, Easement Layouts
The presence of utilities and easements on the Site will be fully investigated prior to the
performance of invasive work such as excavation or drilling under this plan by using, at a
minimum, the One-Call System (811). Underground utilities may pose an electrocution,
explosion, or other hazard during excavation or drilling activities. All invasive activities will be
performed incompliance with applicable laws and regulations to assure safety. Utility companies
and other responsible authorities will be contacted to locate and mark the locations, and a copy
of the Markout Ticket will be retained by the contractor prior to the start of drilling, excavation
or other invasive subsurface operations. Overhead utilities may also be present within the
anticipated work zones. Electrical hazards associated with drilling in the vicinity of overhead
utilities will be prevented by maintaining a safe distance between overhead power lines and drill
rig masts.
Proper safety and protective measures pertaining to utilities and easements, and compliance
with all laws and regulations will be employed during invasive and other work contemplated
under this RAP. The integrity and safety of on-Site and off-Site structures will be maintained
during all invasive, excavation or other remedial activity performed under the RAP.

Dewatering
There will be no dewatering performed during the remedial action.
Equipment and Material Staging
There will no material staging during the remedial action.
3.8 Traffic Control
Drivers of trucks leaving the Site with soil/fill will be instructed to proceed without stopping
in the vicinity of the site to prevent neighborhood impacts.
3.9 Demobilization
Demobilization will include:
As necessary, restoration of temporary access areas and areas that may have been disturbed to accommodate support areas (e.g., staging areas, decontamination areas, storage areas, temporary water management areas, and access area); and
General refuse disposal.
All investigation and remediation derived waste will be appropriately disposed.
3.10 Reporting and Record Keeping
Daily Reports
Daily reports providing a general summary of activities for each day of active remedial work

The frequency of the reporting period may be revised in consultation with OER project
manager based on planned project tasks. Daily email reports are not intended to be the primary
mode of communication for notification to OER of emergencies (accidents, spills), requests for
changes to the RAP or other sensitive or time critical information. However, such information
will be included in the daily reports. Emergency conditions and changes to the RAP will be
communicated directly to the OER project manager by personal communication. Daily reports
will be included as an Appendix in the RCR.
Record Keeping and Photo-Documentation
Job-site record keeping for all remedial work will be performed. These records will be
maintained on-Site during the project and will be available for inspection by OER staff.
Representative photographs will be taken of the Site prior to any remedial activities and during
major remedial activities to illustrate remedial program elements and contaminant source areas.
Photographs will be submitted at the completion of the project in the RCR in digital format
(i.e. jpeg files).
3.11 Complaint Management
All complaints from citizens will be promptly reported to OER. Complaints will be
addressed and outcomes will also be reported to OER in daily reports. Notices to OER will
include the nature of the complaint, the party providing the complaint, and the actions taken to
resolve any problems.
3.12 Deviations from the Remedial Action Plan
All changes to the RAP will be reported to the OER Project Manager and will be
documented in daily reports and reported in the RCR. The process to be followed if there are
any deviations from the RAP will include a request for approval for the change from OER noting
the following:
Reasons for deviating from the approved RAP;

Soil/Materials Management Plan
REMEDIAL ENGINEERING, P.C. – 1 – 2842.0001Y.103/APA
APPENDIX A
Soil/Materials Management Plan
1.1 Soil Screening Methods
Visual, olfactory and PID soil screening and assessment will be performed under the
supervision of a Qualified Environmental Professional and will be reported in the Remedial
Closure Report (RCR). Soil screening will be performed during invasive work performed during
the remedy and development phases prior to issuance of the Notice of Satisfaction.
1.2 Stockpile Methods
Excavated soil from suspected areas of contamination (e.g., hot spots, USTs, drains, etc.)
will be stockpiled separately and will be segregated from clean soil and construction materials.
Stockpiles will be used only when necessary and will be removed as soon as practicable. While
stockpiles are in place, they will be inspected daily, and before and after every storm event.
Results of inspections will be recorded in a logbook and maintained at the Site and available for
inspection by OER. Excavated soils will be stockpiled on, at minimum, double layers of 8-mil
minimum sheeting, will be kept covered at all times with appropriately anchored plastic tarps,
and will be routinely inspected. Broken or ripped tarps will be promptly replaced.
All stockpile activities will be compliant with applicable laws and regulations. Soil
stockpile areas will be appropriately graded to control run-off in accordance with applicable laws
and regulations. Stockpiles of excavated soils and other materials shall be located at least of
50 feet from the property boundaries, where possible. Hay bales or equivalent will surround soil
stockpiles except for areas where access by equipment is required. Silt fencing and hay bales
will be used as needed near catch basins, surface waters and other discharge points.
1.3 Characterization of Excavated Materials
Soil/fill or other excavated media that is transported off-Site for disposal will be sampled in
a manner required by the receiving facility, and in compliance with applicable laws and
regulations. Soils proposed for reuse on-Site will be managed as defined in this plan.
REMEDIAL ENGINEERING, P.C. – 2 – 2842.0001Y.103/APA
1.4 Materials Excavation, Load-Out and Departure
The PE/QEP overseeing the remedial action will:
oversee remedial work and the excavation and load-out of excavated material;
ensure that there is a party responsible for the safe execution of invasive and other work performed under this work plan;
ensure that Site development activities and development-related grading cuts will not interfere with, or otherwise impair or compromise the remedial activities proposed in this RAP;
ensure that the presence of utilities and easements on the Site has been investigated and that any identified risks from work proposed under this plan are properly addressed by appropriate parties;
ensure that all loaded outbound trucks are inspected and cleaned if necessary before leaving the Site; and
ensure that all egress points for truck and equipment transport from the Site will be kept clean of Site-derived materials during Site remediation.
Locations where vehicles exit the Site shall be inspected daily for evidence of soil tracking
off premises. Cleaning of the adjacent streets will be performed as needed to maintain a clean
condition with respect to Site-derived materials.
Open and uncontrolled mechanical processing of historical fill and contaminated soil on-Site
will not be performed without prior OER approval.
1.5 Off-Site Materials Transport
Loaded vehicles leaving the Site will comply with all applicable materials transportation
requirements (including appropriate covering, manifests, and placards) in accordance with
applicable laws and regulations, including use of licensed haulers in accordance with 6 NYCRR
Part 364. If loads contain wet material capable of causing leakage from trucks, truck liners will
be used. Queuing of trucks will be performed on-Site, when possible in order to minimize
off-Site disturbance. Off-Site queuing will be minimized.
REMEDIAL ENGINEERING, P.C. – 3 – 2842.0001Y.103/APA
Outbound truck transport routes are in Section 3.8 of the RAP. This routing takes into
account the following factors: (a) limiting transport through residential areas and past sensitive
sites; (b) use of mapped truck routes; (c) minimizing off-Site queuing of trucks entering the
facility; (d) limiting total distance to major highways; (e) promoting safety in access to
highways; and (f) overall safety in transport. To the extent possible, all trucks loaded with Site
materials will travel from the Site using these truck routes. Trucks will not stop or idle in the
neighborhood after leaving the project Site.
1.6 Materials Disposal Off-Site
The following documentation will be established and reported by the PE/QEP for each
disposal destination used in this project to document that the disposal of regulated material
exported from the Site conforms with applicable laws and regulations: (1) a letter from the
PE/QEP or Applicant to each disposal facility describing the material to be disposed and
requesting written acceptance of the material. This letter will state that material to be disposed is
regulated material generated at an environmental remediation Site in New York under a
governmental remediation program. The letter will provide the project identity and the name and
phone number of the PE/QEP or Applicant. The letter will include as an attachment a summary
of all chemical data for the material being transported; and (2) a letter from each disposal facility
stating it is in receipt of the correspondence (1, above) and is approved to accept the material.
These documents will be included in the RCR.
The RCR will include an itemized account of the destination of all material removed from
the Site during this remedial action. Documentation associated with disposal of all material will
include records and approvals for receipt of the material. This information will be presented in
the RCR.
All impacted soil/fill or other waste excavated and removed from the Site will be managed
as regulated material and will be disposed in accordance with applicable laws and regulations.
Historic fill and contaminated soils taken off-Site will be handled as solid waste and will not be
disposed at a Part 360-16 Registration Facility (also known as a Soil Recycling Facility).
REMEDIAL ENGINEERING, P.C. – 4 – 2842.0001Y.103/APA
Waste characterization will be performed for off-Site disposal in a manner required by the
receiving facility and in conformance with its applicable permits. Waste characterization
sampling and analytical methods, sampling frequency, analytical results and QA/QC will be
reported in the RCR. A manifest system for off-Site transportation of exported materials will be
employed. Manifest information will be reported in the RCR. Hazardous wastes derived from
on-Site will be stored, transported, and disposed of in compliance with applicable laws and
regulations.
1.7 Materials Reuse On-Site
Soil and fill that is derived from the property that meets the soil cleanup objectives
established in this plan may be reused on-Site. The soil cleanup objectives for on-Site reuse are
listed in the RAP. “Reuse on-Site” means material that is excavated during the remedy or
development, does not leave the property, and is relocated within the same property and on
comparable soil/fill material, and addressed pursuant to Engineering Controls. The PE/QEP will
ensure that reused materials are segregated from other materials to be exported from the Site and
that procedures defined for material reuse in this RAP are followed. The expected location for
placement of reused material is shown in the RAP.
Organic matter (wood, roots, stumps, etc.) or other waste derived from clearing and
grubbing of the Site will not be buried on-Site. Soil or fill excavated from the site for grading or
other purposes will not be reused within a cover soil layer or within landscaping berms.
1.8 Demarcation
After completion of hotspot removal and any other invasive remedial activities, and prior to
backfilling, the top of the residual soil/fill will be defined by one of three methods: (1) placement
of a demarcation layer. The demarcation layer will consist of geosynthetic fencing or equivalent
material to be placed on the surface of residual soil/fill to provide an observable reference layer.
A description or map of the approximate depth of the demarcation layer will be provided in the
RCR; or (2) a land survey of the top elevation of residual soil/fill before the placement of cover
soils, pavement and associated sub-soils, or other materials or structures or, (3) all materials
beneath the approved cover will be considered impacted and subject to site management after the
REMEDIAL ENGINEERING, P.C. – 5 – 2842.0001Y.103/APA
remedy is complete. Demarcation may be established by one or any combination of these three
methods. As appropriate, a map showing the method of demarcation for the Site and all
associated documentation will be presented in the RCR. This demarcation will constitute the top
of the site management horizon.
1.9 Import of Backfill Soil from Off-Site Sources
This Section presents the requirements for imported fill materials to be used below the cover
layer and within the clean soil cover layer. All imported soils will meet OER-approved backfill
and cover soil quality objectives for this Site. The backfill and cover soil quality objectives are
listed in the RAP.
A process will be established to evaluate sources of backfill and cover soil to be imported to
the Site, and will include an examination of source location, current and historical use(s), and
any applicable documentation. Material from industrial sites, spill sites, environmental
remediation sites or other potentially contaminated sites will not be imported to the Site.
The following potential sources may be used pending attainment of backfill and cover soil
quality objectives:
Clean soil from construction projects at non-industrial sites in compliance with applicable laws and regulations;
Clean soil from roadway or other transportation-related projects in compliance with applicable laws and regulations; and
Clean recycled concrete aggregate (RCA) from facilities permitted or registered by the regulations of NYS DEC.
All materials received for import to the Site will be approved by a PE/QEP and will be in
compliance with provisions in this RAP. The RCR will report the source of the fill, evidence
that an inspection was performed on the source, chemical sampling results, frequency of testing,
and a Site map indicating the locations where backfill or soil cover was placed.
REMEDIAL ENGINEERING, P.C. – 6 – 2842.0001Y.103/APA
Source Screening and Testing
Inspection of imported fill material will include visual, olfactory and PID screening for
evidence of contamination. Materials imported to the Site will be subject to inspection, as
follows:
Trucks with imported fill material will be in compliance with applicable laws and regulations and will enter the Site at designated locations;
The PE/QEP is responsible to ensure that every truck load of imported material is inspected for evidence of contamination; and
Fill material will be free of solid waste including pavement materials, debris, stumps, roots, and other organic matter, as well as ashes, oil, perishables or foreign matter.
Composite samples of imported material will be taken at a minimum frequency of one
sample for every 500 cubic yards of material. Once it is determined that the fill material meets
imported backfill or cover soil chemical requirements and is non-hazardous, and lacks petroleum
contamination, the material will be loaded onto trucks for delivery to the Site.
Recycled concrete aggregate (RCA) will be imported from facilities permitted or registered
by NYSDEC. Facilities will be identified in the RCR. A PE/QEP is responsible to ensure that
the facility is compliant with 6NYCRR Part 360 registration and permitting requirements for the
period of acquisition of RCA. RCA imported from compliant facilities will not require
additional testing, unless required by NYSDEC under its terms for operation of the facility.
RCA imported to the Site must be derived from recognizable and uncontaminated concrete.
RCA material is not acceptable for, and will not be used as cover material.
1.10 Fluids Management
All liquids to be removed from the Site, including dewatering fluids, will be handled,
transported and disposed in accordance with applicable laws and regulations. Liquids discharged
into the New York City sewer system will receive prior approval by New York City Department
of Environmental Protection (NYC DEP). The NYC DEP regulates discharges to the New York
City sewers under Title 15, Rules of the City of New York Chapter 19. Discharge to the
New York City sewer system will require an authorization and sampling data demonstrating that
the groundwater meets the City’s discharge criteria. The dewatering fluid will be pretreated as
REMEDIAL ENGINEERING, P.C. – 7 – 2842.0001Y.103/APA
necessary to meet the NYC DEP discharge criteria. If discharge to the City sewer system is not
appropriate, the dewatering fluids will be managed by transportation and disposal at an off-Site
treatment facility.
Discharge of water generated during remedial construction to surface waters (i.e. a stream or
river) is prohibited without a SPDES permit issued by New York State Department of
Environmental Conservation.
1.11 Storm-water Pollution Prevention
Applicable laws and regulations pertaining to storm-water pollution prevention will be
addressed during the remedial program. Erosion and sediment control measures identified in this
RAP (silt fences and barriers, and hay bale checks) will be installed around the entire perimeter
of the remedial construction area and inspected once a week and after every storm event to
ensure that they are operating appropriately. Discharge locations will be inspected to determine
whether erosion control measures are effective in preventing significant impacts to receptors.
Results of inspections will be recorded in a logbook and maintained at the Site and available for
inspection by OER. All necessary repairs shall be made immediately. Accumulated sediments
will be removed as required to keep the barrier and hay bale check functional. Undercutting or
erosion of the silt fence anchor will be repaired immediately with appropriate backfill materials.
Manufacturer's recommendations will be followed for replacing silt fencing damaged due
to weathering.
1.12 Contingency Plan
This contingency plan is developed for the remedial construction to address the discovery of
unknown structures or contaminated media during excavation. Identification of unknown
contamination source areas during invasive Site work will be promptly communicated to OER’s
Project Manager. Petroleum spills will be reported to the NYS DEC Spill Hotline. These
findings will be included in the daily report. If previously unidentified contaminant sources are
found during on-Site remedial excavation or development-related excavation, sampling will be
performed on contaminated source material and surrounding soils and reported to OER.
REMEDIAL ENGINEERING, P.C. – 8 – 2842.0001Y.103/APA
Chemical analytical testing will be performed for Full List volatiles and semi-volatiles,
pesticides/PCBs, and TAL metals, as appropriate.
1.13 Odor, Dust and Nuisance Control
Odor Control
All necessary means will be employed to prevent on- and off-Site odor nuisances. At a
minimum, procedures will include: (a) limiting the area of open excavations; (b) shrouding open
excavations with tarps and other covers; and (c) use of foams to cover exposed odorous soils.
If odors develop and cannot otherwise be controlled, additional means to eliminate odor
nuisances will include: (d) direct load-out of soils to trucks for off-Site disposal; and (e) use of
chemical odorants in spray or misting systems.
This odor control plan is capable of controlling emissions of nuisance odors. If nuisance
odors are identified, work will be halted and the source of odors will be identified and corrected.
Work will not resume until all nuisance odors have been abated. OER will be notified of all odor
complaint events. Implementation of all odor controls, including halt of work, will be the
responsibility of the PE/QEP’s certifying the RCR.
Dust Control
Dust management during invasive on-Site work will include, at a minimum:
Use of a dedicated water spray methodology for roads, excavation areas and stockpiles.
Use of properly anchored tarps to cover stockpiles.
Exercise extra care during dry and high-wind periods.
Use of gravel or recycled concrete aggregate on egress and other roadways to provide a clean and dust-free road surface.
This dust control plan is capable of controlling emissions of dust. If nuisance dust emissions
are identified, work will be halted and the source of dusts will be identified and corrected.
Work will not resume until all nuisance dust emissions have been abated. OER will be notified
of all dust complaint events. Implementation of all dust controls, including halt of work, will be
the responsibility of the PE/QEP’s responsible for certifying the Remedial Closure Report.
REMEDIAL ENGINEERING, P.C. – 9 – 2842.0001Y.103/APA
Other Nuisances
Noise control will be exercised during the remedial program. All remedial work will
conform, at a minimum, to NYC noise control standards.
Rodent control will be provided, during Site clearing and grubbing, and during the remedial
program, as necessary, to prevent nuisances.
1.14 Import of Clean Cover
No soil is anticipated to have to be imported into the Site for use as clean cover. If required, all
imported soil will be uncontaminated, clean soil that meets the lesser of the appropriate
NYSDEC 6 NYCRR Part 375-6.8(a) Unrestricted Use SCOs and the NYSDEC 6 NYCRR Part
375-6.8 groundwater protection SCOs.
The imported uncontaminated, clean soil cover will be from an approved source/facility and will
be evaluated by the PE/QEP to ensure:
1. That a segregated stockpile is properly maintained at the source and will not be comingled with any other material prior to importing and grading the clean soil material at the Site;
2. That the material does not include any solid waste, including construction and demolition material, as it’s prohibited;
3. That screening for evidence of contamination by visual, olfactory and PID soil screening practices prior to testing at the source as well as upon importing to the Site for grading is completed; and
4. That a maximum five-part composite sample will be collected from the segregated stockpile at the source at a minimum frequency of one sample per 250 cubic yards and analyzed for the following Full List parameters:
VOCs by EPA Method 8260C (rev. 2006)
SVOCs by EPA Method 8270D (rev. 2007)
Pesticides by EPA Method 8081B (rev. 2000)
PCBs by EPA Method 8082A (rev. 2000)
TAL Metals by EPA Method 6010C (rev. 2007)
REMEDIAL ENGINEERING, P.C. – 10 – 2842.0001Y.103/APA
Upon receipt of the segregated stockpile analytical results collected at the source, a Clean
Soil Sampling Report will be submitted to OER for review/approval prior to importing. The
report will include the following:
1. Summary of number of samples collected and analyzed, tabulated data and comparison to the selected Site Use SCOs;
2. Analytical data sheets and chain of custody documentation;
3. Summary of tons (cubic yards);
4. Photographs from the segregated stockpile at the source with sample point locations identified;
5. An affidavit from the source/facility on company letterhead stating that the segregated stockpile has been properly maintained at the source and complies with the requirements listed above; and
6. A copy of source/facility NYSDEC permit.
A highly visible demarcation barrier (i.e. orange geo-synthetic material or equivalent) will
be installed beneath the clean soil/fill surface cover. Upon importing and grading the OER
approved clean soil cover on top of a highly visible demarcation barrier, the following
documentation will be presented in the Final Remedial Closure Report:
1. Copies of purchase invoices;
2. Truck transportation slips from the source to the Site;
3. Confirmation of the number of tons (number cubic yards) of OER approved clean soil cover material imported and graded at the site on top of highly visible demarcation barrier;
4. Site plan depicting all areas where the OER approved clean soil cover has been placed; and
5. Photographs documenting the importing and grading of the OER approved clean soil cover across the site with the underlying highly visible demarcation barrier (i.e. orange geo-synthetic material or equivalent).
