Executive Summary In accordance with our Asbestos Term Agreement (Downstate - D031071) with New York State Department of Transportation (NYSDOT), Environmental Planning and Management, Inc. (EPM, Inc.), as a subconsultant to L.K. McLean Associates, P.C. (LKMA), performed an inspection and sampling of the structure associated with the Critical Bridges over Water – East 3rd Street over Route 907W / Hutchinson River (BIN 5500050), Town of Pelham, Westchester County (PIN 8BOW.00.101) for the presence of asbestos-containing materials (ACM). Prior to the field inspection of the structure, available As-Built diagrams were reviewed to determine the potential presence of ACM and suspect asbestos-containing material (SACM). The inspection was performed on August 9th, 2014 and September 5th, 2014 by EPM staff (Darren Frank – Certificate #02-21260, Daniel Kardashian – Certificate #14-12786 and Kevin Goddard - Certificate #13-21618) who are New York State Department of Labor (NYSDOL) certified asbestos inspectors. The purpose of the inspection was to identify the location, quantity and general removal options (including cost estimate) of the asbestos-containing materials (greater than 1% as measured by PLM, and TEM) present in the structure in accordance with New York State Industrial Code Rule 56 (ICR 56). A total of 15 bulk samples of the following types of materials were collected from the bridge:
Brown Joint Filler Black Joint Filler Gray Paint (on Concrete) Old White Caulk Brown Sidewalk Joint Filler
In addition, the following suspect asbestos containing material (SACM) identified, but not sampled due to inaccessibility, included;
Pipe wrap/mastic potentially located on gas conduits encased within the north and south concrete sidewalks (utility mark-outs were observed during the site visit);
Conduit material potentially asbestos containing as related to Con Edison conduits concrete encased within span of bridge (utility mark-outs were observed during the site visit);
Electrical components (such as cable insulation, arc wrap and duct seal) potentially located within Con Edison manholes and conduits concrete encased within span of bridge (manholes and utility mark-outs were observed during the site visit);
Conduit material potentially asbestos containing as related to communication lines concrete encased within span of bridge (utility mark-outs were observed during the site visit).
The samples were delivered to Alpha Labs, located at 14-26 28th Avenue, Long Island City, New York, for analysis by Polarized Light Microscopy (PLM), and by Transmission Electron Microscopy (TEM), where applicable. In accordance with the NYSDOT protocol, if PLM analysis did not detect any asbestos in non-friable organically bound (NOB) samples, the

2.0 ASBESTOS SURVEY
This inspection consisted of a visual survey along with sample collection of suspect ACM present at the subject structure. In addition, record plans for the bridge were available and were reviewed during the inspection. A list of the provided records plans that were examined is presented in Appendix A.
In accordance with the NYSDOT scope of work, three bulk samples (when possible) of suspect ACM were collected from each homogeneous material observed. A total of 15 bulk ACM samples from the structure were collected for laboratory analysis. The sampling was conducted using protocol established by the USEPA and as required by NYSDOL's Industrial Code Rule 56. Utilizing amended water and a knife, chisel or pliers a small amount of suspect ACM was obtained and placed immediately into a zip-lock bag and sealed. The bag was then labeled and the sample information recorded on a sampling log/chain-of-custody form. All samples were "double-bagged" for shipment to the analytical laboratory. A description of the suspect ACM sampled during the field survey and/or identified from a review of the provided record plans is presented below:
Brown Joint Filler Three (3) samples of a brown fibrous joint filler were collected. This material is present within the vertical joints of jersey barriers located underdeck. This non-friable material was in good condition.
Black Joint Filler
Three (3) samples of a black fibrous joint filler were collected. This material is present within the vertical joint between the concrete stemwall of piers/abutments and stone face and along the horizontal joint (running along base of piers and abutments). This non-friable material was in good condition.
Gray Paint (on Concrete)
Three (3) samples of a thin grey paint were collected. This material is present on the underside of the bridge from the top of the Jersey barrier to the bottom of the deck. This non-friable material was in good condition.
Old White Caulk Three (3) samples of an old white deteriorated caulk were collected. This material is present as crack repair on the northeast and southeast wingwalls. This non-friable material was in poor condition.
Brown Sidewalk Joint Filler
Three (3) samples of a fibrous brown joint filler were collected. This material is present within concrete sidewalk joints of the southwest sidewalk on the top of the span. This non-friable material was in good condition.

In addition, the following suspect asbestos containing material (SACM) identified, but not sampled due to inaccessibility, included;
Pipe wrap/mastic potentially located on gas conduits encased within the north and south concrete sidewalks (utility mark-outs were observed during the site visit);
Conduit material potentially asbestos containing as related to Con Edison conduits concrete encased within span of bridge (utility mark-outs were observed during the site visit).
Electrical components (such as cable insulation, arc wrap and duct seal) potentially located within Con Edison manholes and conduits concrete encased within span of bridge (manholes and utility mark-outs were observed during the site visit);
Conduit material potentially asbestos containing as related to communication lines concrete encased within span of bridge (utility mark-outs were observed during the site visit).
As-Built Record Plans did not indicate the presence of a waterproofing membrane on the
bridge deck.
As per NYSDOT, this site is not suspect for the presence of an asbestos-containing structural steel paint coating as the bridge is a pre-stressed concrete beam structure.
Neither As-Built Record Plans, nor field observations, indicated the presence of bearing pads underneath the ends of the beams.
Neither As-Built Record Plans, nor field observations, indicated the presence of Bond
Breaker Slip Sheet. The bulk ACM sampling log/chain-of-custody forms for the samples collected are presented in Appendix B. The location from which each sample was collected is shown on the bridge diagram presented in Appendix C. As a reference, Appendix D presents typical suspect asbestos containing materials and their associated descriptions. Similarly, Appendix E presents diagrams of typical bridge elements for general information purposes.

3.0 LABORATORY ANALYSIS 3.1 Analytical Procedures
The bulk samples were delivered to Alpha Labs, located at 14-26 28th Avenue, Long Island City, New York. This laboratory is accredited by the New York State Environmental Laboratory Accreditation Program (ELAP #11833) and the National Voluntary Laboratory Accreditation Program (NVLAP # 200691-0). Accreditation certifications for the laboratory are provided in Appendix F The samples were analyzed by Polarized Light Microscopy (PLM). Bulk sample analysis is accomplished by using a polarized light microscope equipped with dispersion staining as described by the Interim Method for the Determination of Asbestos in Bulk Insulation, Federal Register/Volume 47, No. 103/May 27, 1987. The method of analysis involves the immersion of a suspect material in a solution of known refractive index and the subjection to illumination by polarized light. The resulting color displays enable mineral identification. According to ELAP guidelines, quantitative Transmission Electron Microscopy (TEM) analysis is the only method that can be used to determine if Non-friable Organically Bound (NOB) materials can be considered non-asbestos containing. Therefore, NOB samples determined to be inconclusive by PLM analysis must be verified through TEM analysis. According to NYSDOT protocol, the laboratory was instructed to re-analyze the samples from each set of homogeneous NOB materials using TEM analysis, until a positive result for asbestos was found or all samples of the group were analyzed.
3.2 Analytical Results
A summary of all the laboratory analysis results of the bulk samples collected is presented in Table 2 at the end of this section. The laboratory analysis reports are included in Appendix G. The laboratory analysis indicated that two (2) of the materials collected contained greater that 1% asbestos.
Photographs of the suspect asbestos-containing material are presented in Appendix H.

2.0 ASBESTOS SURVEY
This inspection consisted of a visual survey along with sample collection of suspect ACM present at the subject structure. In addition, record plans for the bridge were available and were reviewed during the inspection. A list of the provided records plans that were examined is presented in Appendix A.
In accordance with the NYSDOT scope of work, three bulk samples (when possible) of suspect ACM were collected from each homogeneous material observed. A total of 9 bulk ACM samples from the structure were collected for laboratory analysis. The sampling was conducted using protocol established by the USEPA and as required by NYSDOL's Industrial Code Rule 56. Utilizing amended water and a knife, chisel or pliers a small amount of suspect ACM was obtained and placed immediately into a zip-lock bag and sealed. The bag was then labeled and the sample information recorded on a sampling log/chain-of-custody form. All samples were "double-bagged" for shipment to the analytical laboratory. A description of the suspect ACM sampled during the field survey and/or identified from a review of the provided record plans is presented below:
Road Tar Three (3) samples of a hard black tar were collected. This material is located across the wearing surface of the bridge span. This non-friable material was in good condition.
Brown Joint Filler
Three (3) samples of a soft brown joint filler were collected. This material is located within joints within the median. This non-friable material was in fair condition.
Tar in Rail Post Socket
Three (3) samples of a bituminous black tar were collected. This material is located within rail socket post in median. This non-friable material was in good condition.
No waterproofing membrane is indicated within the bridge deck.
As-Built Record Plans did not indicate the presence of utilities on and/or underneath the bridge; however, a non-suspect metal conduit was observed running along the west parapet of the bridge. This conduit may have been installed as part of the 1985 Safety Improvement Project.
Concrete coatings were not observed on any exterior surfaces of the abutments or wingwalls.
As per NYSDOT, this site is not suspect for the presence of an asbestos-containing structural steel paint coating as the bridge is a concrete structure.
As-Built Record Plans did not indicate the presence of waterproofing on the earth side of the abutment backwalls and wingwalls. For confirmation, several test holes were
progressed on the earth side of the end abutment wingwalls, down to a depth of 2 feet, and evidence of a waterproofing material was not detected.
The bulk ACM sampling log/chain-of-custody forms for the samples collected are presented in Appendix B. The location from which each sample was collected is shown on the bridge diagram presented in Appendix C. As a reference, Appendix D presents typical suspect asbestos containing materials and their associated descriptions. Similarly, Appendix E presents diagrams of typical bridge elements for general information purposes.

3.0 LABORATORY ANALYSIS 3.1 Analytical Procedures
The bulk samples were delivered to Alpha Labs, located at 14-26 28th Avenue, Long Island City, New York. This laboratory is accredited by the New York State Environmental Laboratory Accreditation Program (ELAP #11833) and the National Voluntary Laboratory Accreditation Program (NVLAP # 200691-0). Accreditation certifications for the laboratory are provided in Appendix F. The samples were analyzed by Polarized Light Microscopy (PLM). Bulk sample analysis is accomplished by using a polarized light microscope equipped with dispersion staining as described by the Interim Method for the Determination of Asbestos in Bulk Insulation, Federal Register/Volume 47, No. 103/May 27, 1987. The method of analysis involves the immersion of a suspect material in a solution of known refractive index and the subjection to illumination by polarized light. The resulting color displays enable mineral identification. According to ELAP guidelines, quantitative Transmission Electron Microscopy (TEM) analysis is the only method that can be used to determine if Non-friable Organically Bound (NOB) materials can be considered non-asbestos containing. Therefore, NOB samples determined to be inconclusive by PLM analysis must be verified through TEM analysis. According to NYSDOT protocol, the laboratory was instructed to re-analyze the samples from each set of homogeneous NOB materials using TEM analysis, until a positive result for asbestos was found or all samples of the group were analyzed.
3.2 Analytical Results
A summary of all the laboratory analysis results of the bulk samples collected is presented in Table 1 at the end of this section. The laboratory analysis reports are included in Appendix G. The laboratory analyses did not identify asbestos-containing material (i.e., > 1% asbestos) in any of the samples collected.

Executive Summary In accordance with our Asbestos Term Agreement (Downstate - D030925) with New York State Department of Transportation (NYSDOT), L.K. McLean Associates, P.C. (LKMA) performed an inspection and sampling of the structure associated with the Region 8 Bridge Replacement on Saw Mill River Parkway over Saw Mill River (BIN 5500739), Town of Greenburgh, Westchester County (PIN 8812.00.101) for the presence of asbestos-containing materials (ACM). Prior to the field inspection of the structure, available As-Built diagrams were reviewed to determine the potential presence of ACM and suspect asbestos-containing material (SACM). The inspection was performed on May 24, 2012 by LKMA staff (Thomas Luck - Certificate #06-14004, and Chris White - Certificate #09-19928) who are New York State Department of Labor (NYSDOL) certified asbestos inspectors. The purpose of the inspection was to identify the location, quantity and general removal options (including cost estimate) of the asbestos-containing materials (greater than 1% weight) present in the structures in accordance with New York State Industrial Code Rule 56 (ICR 56). A total of (9) bulk samples of the following types of materials were collected from the bridge:
• Joint Fillers • Joint Sealer
In addition, the following suspect asbestos containing material (SACM) was identified on the As-Built diagrams but not sampled due to inaccessibility:
• Concrete Encased Fiber Ducts The samples were delivered to Enviroscience Laboratories, Inc., 2150 Smithtown Avenue, Ronkonkoma, N.Y., for analysis by Polarized Light Microscopy (PLM), and by Transmission Electron Microscopy (TEM), where applicable. In accordance with the NYSDOT protocol, if PLM analysis did not detect any asbestos in non-friable organically bound (NOB) samples, the laboratory was instructed to re-analyze the samples from each set of homogeneous materials using TEM analysis until a positive result for asbestos was found or all samples of the group were analyzed. A summary of the identified asbestos-containing materials (i.e., >1% asbestos by weight) found at the structure and identification of unsampled suspect asbestos-containing material, along with a description, location, and quantity, are presented in Table 1 following this section. The table shows that SACM was identified at the bridge. Figure 1 is an illustration of the structure depicting the location of the identified material. Table 2 summarizes the sampling locations, material descriptions, and analytical results for all samples collected. A site location map of the structure inspected is provided in Figure 2. Photographs of the identified SACM are presented in Appendix H. Other appendices are listed in the Table of Contents.

The inspection was performed on May 24, 2012 by LKMA staff (Thomas Luck - Certificate #06-14004, and Chris White - Certificate #09-19928) who are New York State Department of Labor (NYSDOL) certified asbestos inspectors. The scope of work consisted of the following tasks:
- Review available record plans to determine the potential presence of ACM and/or SACM at the existing structure.
- Conduct a site visit and a visual inspection of the bridge to identify potential locations of
ACM. - Collect bulk samples of suspected ACM from each homogenous area in accordance with
standard industry protocols. - Submit bulk samples to a New York State Department of Health (NYSDOH) or United
States Environmental Protection Agency (USEPA) approved laboratory participating in the Environmental Laboratory Approval Program (ELAP). Analyze the samples using Polarized Light Microscopy (PLM) to determine the amount of asbestos present. Continue to analyze Non-Friable Organically Bound (NOB) samples of a homogeneous sample set using Transmission Electron Microscopy (TEM) until a positive ACM result is confirmed or all NOB samples in the set are analyzed.
- Document the results of the investigation findings in a report which includes:
a. A summary of the data collection techniques and laboratory analysis procedures
used. b. Identification of the location, type and quantities of ACM observed which contain
greater than 1% asbestos. c. Applicability of NYSDOL approved "Blanket Variance 14" and identification of which
ACM can be removed under this variance. d. Recommendation of specifications suitable for ACM removal and supply
supplemental information which may be required. e. Cost estimate for the removal of ACM containing greater than 1% asbestos by
weight.

2.0 ASBESTOS SURVEY
This inspection consisted of a visual survey along with sample collection of suspect ACM present at the subject structure. In addition, record plans for the bridge were available and were reviewed during the inspection. A list of the provided records plans that were examined is presented in Appendix A.
In accordance with the NYSDOT scope of work, three bulk samples (when possible) of suspect ACM were collected from each homogeneous material observed. A total of 9 bulk ACM samples from the structure were collected for laboratory analysis. The sampling was conducted using protocol established by the USEPA and as required by NYSDOL's Industrial Code Rule 56. Utilizing amended water and a knife, chisel or pliers a small amount of suspect ACM was obtained and placed immediately into a zip-lock bag and sealed. The bag was then labeled and the sample information recorded on a sampling log/chain-of-custody form. All samples were "double-bagged" for shipment to the analytical laboratory. Sampling locations were marked with a covering of orange or red spray paint and labeled with the sample number. A description of the suspect ACM sampled during the field survey and/or identified from a review of the provided record plans is presented below:
• Joint Filler (JF)
Two different joint filler materials were observed on the structure from which a total of 6 samples were collected.
JF1 – Three (3) samples of a soft, dark brown, fibrous sheet joint filler were collected. This material is present in the vertical joints between the concrete barrier sections along the right side of the bridge only. The non-friable material was in good condition.
JF2 – Three (3) samples of a firm, dark brown, fibrous sheet joint filler were collected. This material is present in the transverse abutment joints, between the concrete deck slab and approach slabs. The non-friable material was in fair-good condition.
• Joint Sealer (JS)
Three (3) samples of a soft, black, gooey, tacky, bituminous joint sealer were collected. This material is present in various transverse/longitudinal deck joints/cracks on the bridge deck and approaches. The non-friable material was in good condition.
• As indicated on the As-Built Diagrams, a 4” dia. Fiber Duct is encased inside the concrete
beam on the left side of the bridge, and extending only 6” beyond the abutment at each end. Due to inaccessibility, this suspect ACM was not sampled.
• As indicated on the As-Built Diagrams, a 4” dia. Fiber Duct was encased inside the concrete beam on the right side of the bridge during the 1929 construction. However, the 1966 Bridge Widening plans called for the partial removal of structural concrete along the right side of the bridge. The existing 4” Duct was located within the limits of removal, and therefore, is no longer expected to be present.

The bulk ACM sampling log/chain-of-custody forms for the samples collected are presented in Appendix B. The location from which each sample was collected is shown on the bridge diagram presented in Appendix C. Samples collected were identified using an alpha/numeric descriptor. The system established uses the Bridge Identification Number, a code for type of material being sampled (see Asbestos Sample Legend in Appendix D) and the set for the number of homogenous types observed, and the number of samples from that homogenous type that was collected. For example:
Sample ID number: 1060020 - JF1 - A
Means: BIN 1060020 – Joint Filler (1st type) – first sample
In addition, for bridge sampling projects, the description of the sampling locations provided is based on the methodology presented in the NYSDOT Bridge Inspection Manual. The “Begin” side is determined as the side of the bridge someone would stand on while looking across the bridge in the direction of the bridge orientation (a compass heading established and provided by NYSDOT). The opposite side of the bridge is the “End” side. Bridge Span sections would be labeled sequentially starting from the Begin Abutment towards the End Abutment. Girders within each Span would be labeled sequentially from left to right. Some terms used for the identification of various bridge elements from which samples were collected are presented in the diagrams found in Appendix E.

3.0 LABORATORY ANALYSIS 3.1 Analytical Procedures
The bulk samples were delivered to Enviroscience Consultants, Inc. laboratories (Enviroscience), located at 2150 Smithtown Avenue, Ronkonkoma, New York. This laboratory is accredited by the New York State Environmental Laboratory Accreditation Program (ELAP #11681) and the National Voluntary Laboratory Accreditation Program (NVLAP # 200531-0). Accreditation certifications for the laboratory are provided in Appendix F. The samples were analyzed by Polarized Light Microscopy (PLM). Bulk sample analysis is accomplished by using a polarized light microscope equipped with dispersion staining as described by the Interim Method for the Determination of Asbestos in Bulk Insulation, Federal Register/Volume 47, No. 103/May 27, 1987. The method of analysis involves the immersion of a suspect material in a solution of known refractive index and the subjection to illumination by polarized light. The resulting color displays enable mineral identification. According to ELAP guidelines, quantitative Transmission Electron Microscopy (TEM) analysis is the only method that can be used to determine if Non-friable Organically Bound (NOB) materials can be considered non-asbestos containing. Therefore, NOB samples determined to be inconclusive by PLM analysis must be verified through TEM analysis. According to NYSDOT protocol, the laboratory was instructed to re-analyze the samples from each set of homogeneous NOB materials using TEM analysis, until a positive result for asbestos was found or all samples of the group were analyzed.
3.2 Analytical Results
A summary of all the laboratory analysis results of the bulk samples collected is presented in Table 2 at the end of this section. The laboratory analysis reports are included in Appendix G. The laboratory analysis indicated that none of the materials collected contained greater than 1% asbestos by weight.
Photographs of the suspect asbestos-containing materials identified in record plans are presented in Appendix H.

This work shall consist of designing, furnishing, installing, and testing an internally stabilized cut structure at the location(s) and to the elevation(s) shown in the contract documents. 211-1.01 Soil Nail Wall System. A Soil Nail Wall System is comprised of cement-grouted steel nail tendons, a drainage network and a facing system to internally stabilize a cut and/or underpin a structure.
A. Soil Nail Wall System (SNWS) Definitions. 1. Soil Nail. A passive reinforcing element which develops its reinforcing action through nail
tendon/ground interaction. A soil nail includes the SNWS nail tendon, the SNWS nail head, grout, coatings, sheathing, couplers and encapsulation if used.
2. SNWS Nail Tendon. A steel bar installed into a slope to reinforce and strengthen the existing ground.
3. SNWS Nail Head. The nail head consists of the bearing plate and headed-stud. The bearing plate distributes forces at the nail end to the wall and ground behind the facing. The headed-stud provides anchorage of the nail head into the permanent facing.
4. Grout. Grout is used primarily as a transfer mechanism for stresses from the wall to the ground. The grout also provides a level of corrosion protection.
5. Centralizers. Centralizers are devices, typically PVC, installed at various locations along the length of the nail tendon to center the bar in the excavated hole to ensure a minimum thickness of grout cover.
6. Corrosion Protection Elements. These are physical and/or chemical coatings or systems used to inhibit corrosion. Nail tendons may have a fusion-bonded epoxy coating applied. For maximum protection, encapsulation consists of surrounding the nail tendon with a HDPE or PVC corrugated protective sheathing and filling the internal annulus with grout. Subsequent to installing the encapsulated nail into the excavated hole, the outer annulus is also filled with grout.
7. Temporary Wall Facing. This consists of reinforced shotcrete installed to provide a connection between nail tendons, support the exposed soil within the nail tendon grid and provide protection against erosion and sloughing of the soil at the excavation face.
8. Wall Drainage Network. A system of drainage devices installed to prevent water pressure from developing behind the wall face. The system typically consists of a series of vertical geocomposite drainage strips and weep holes. Additional devices include footing drains and horizontal drains.
9. GUTS. The Guaranteed Ultimate Tensile Strength of the tendon.
