1.0 INTRODUCTION AND PURPOSE 1.1

INTRODUCTION

This report presents the findings of a preliminary Asbestos, Lead and Hazardous Material Survey conducted by GZA GeoEnvironmental, Inc. (GZA) for the building located at 25 Crown Street in Nashua, New Hampshire (Site). The report has been prepared for the City of Nashua (the City). The survey was conducted on April 7, 2015 in general accordance with GZA’s Proposal No. 04.P000340.15 dated March 4, 2015. Authorization to proceed was obtained on March 11, 2015. This report is subject to the Limitations in Appendix A. 1.2

PROJECT OBJECTIVE

GZA understands that the City is considering razing the existing the 2-story warehouse building currently occupying the site. The objective of our work was to perform a walkthrough of the accessible portions of the above-referenced building to identify and evaluate the condition of suspect asbestos-containing material (ACM), lead-containing paint (LCP), and other visually observed universal wastes (UW), and hazardous materials. The work included the collection of bulk samples of observed representative suspect ACMs, LCP, and caulking, glazing, paints or sealants suspected of containing polychlorinated biphenyls (PCBs) and the quantification of identified ACMs and hazardous materials. 1.3

PROJECT STRATEGY

Based on GZA’s understanding that no prior evaluations of hazardous building materials (i.e., asbestos, paint, PCBs, UW, and other hazardous materials) have been conducted at the Site, the objective of our services is to assist the City in identifying potential hazardous building materials that may impact demolition plans. Efforts were made to access the interiors of pipe chases and wall cavities by using available access hatches, but it should be noted that certain interstitial building voids and spaces could not be accessed without disassembly of the building or use of destructive methods. Charged electrical systems and energized mechanical and pneumatic equipment were not sampled as part of this survey. GZA did not dismantle mechanical equipment within the building. Although reasonable effort was made to survey accessible suspect materials, additional suspect but un-sampled materials could be located in walls, voids or in other concealed areas. Furthermore, it is assumed that no active effort, intentional or otherwise, was made to cosmetically hide potentially salient features or conditions from GZA.

2.0 SITE DESCRIPTION The approximately 54,000-square-foot building at the Site consists of a 2-story, concrete masonry unit (CMU) block structure with a basement crawlspace. Exterior cladding consists of a combination of painted concrete block, and a brick façade. The main roof consists of a rubber membrane system; the sloped roof system covering the exterior staircase along the north wall consists of asphalt shingles. The windows were double-hung wood units. The exterior consists of a paved driveway along the west side of the building that wraps around to the south side of 04.0190213.00

the building to the garage bays. The northern exterior consists of a landscaped area and the eastern exterior is fenced in and adjacent to the railroad tracks. Heat for the building is provided by ceiling-mounted, natural gas-fired space heater units. Domestic hot water is supplied by an electric water heater. The crawlspace floor area is unfinished with a sand and gravel surface. The crawlspace wall areas consisted of unfinished CMU with brick along the north wall. The first floor consists of offices, bathroom, break room, assembly area, storage room, and shipping. Garage bays and a loading dock were located at the south end of the building. Interior ceilings were open to the second floor joists and corrugated metal decking, with 2-foot by 4-foot suspended ceiling tile located in the office area. Wall surfaces throughout the first floor consist of CMU block with a painted finish. On the northern walls of the building, there was a brick façade. Office and bathroom walls consist of gypsum board with a painted finish. Flooring surfaces throughout the first floor consist of unfinished concrete, with adhered carpet in the office area. In the center of the first floor, a conveyor belt traverses to the second floor. The second floor consists of an open concept warehouse. Interior ceilings consisted of corrugated steel roof decking with cementitious panel ceiling partitions approximately every 100 feet. Wall surfaces throughout the second floor consist of CMUs, with brick along the north wall. Flooring surfaces throughout the second floor consist of concrete with a polished finish.

3.0 SCOPE OF SERVICES The scope of work involved visually identifying and classifying conditions within the building, collecting representative samples of suspect materials for analysis, and integrating and reporting our findings in a written report. GZA observed building structural components; utility systems (electrical, mechanical, and plumbing); designated interior spaces, building contents; and the suspect materials comprising or associated with the building exterior scheduled to be impacted by the upcoming demolition plans. GZA was provided full access to the building.

4.0 INVESTIGATION PROCEDURES Results of the investigation are described below. 4.1

ASBESTOS INVESTIGATION

The asbestos sampling conducted at the site on April 7, 2015, was performed by Mr. Jeremy Boucher, a State of New Hampshire-certified Asbestos Inspector (Certificate #AI000435). A copy of Mr. Boucher’s asbestos inspector certificate is attached as Appendix B.

4.1.1

Pre-Demolition Asbestos Survey

The limited asbestos survey was conducted throughout the interior and exterior of the building. Accessible building components were surveyed and homogeneous areas of suspect ACMs were visually identified and documented. Roofing materials on the main roof field were not sampled as part of this scope of work. Procedures for locating and identifying ACM were based on guidelines published by the United States Environmental Protection Agency (USEPA).1 A homogeneous area consists of building materials that appear similar throughout in terms of color, texture and date of application. Building materials identified as concrete, glass, wood, masonry, metal or rubber were not considered suspect ACM. A physical assessment of each homogeneous area of suspect ACM was conducted to assess the friability and condition of the materials. A friable material is defined by the USEPA as a material which can be crumbled, pulverized or reduced to powder by hand pressure when dry. Friability was assessed by physically touching suspect materials. Based on results of the visual observation, bulk samples of suspect ACM were collected in general accordance with the sampling protocols outlined in USEPA Regulation 40 CFR 763 Asbestos Hazard Emergency Response Act and the New Hampshire Department of Environmental Services regulation Env, 1800. It was assumed that discrete suspect ACM were sufficiently uniform in composition to permit random samples to be collected of suspect materials in each homogeneous area. GZA collected bulk samples wearing appropriate Personal Protection Equipment and using wet methods as applicable to reduce the potential for fiber release. Samples were placed in individual re-sealable plastic bags, wet wiped of visible debris, labeled with unique sample numbers using an indelible marker recorded and dispatched to an accredited laboratory for analysis following chain-of-custody (COC) protocol. In total, 43 bulk samples were collected from 21 homogeneous areas of suspect ACM. A summary of suspect ACM samples collected during the survey are presented in Table 1. 4.1.2

Sample Analysis

Bulk samples were submitted under COC to EMSL Analytical, Inc. (EMSL) of Plymouth Meeting, Pennsylvania for analysis by using polarized light microscopy with dispersion staining techniques per USEPA methodology (40 CFR 763, Subpart F). The percentage of asbestos, where applicable, was determined by microscopical visual estimation. EMSL is accredited under the National Voluntary Laboratory Accreditation Program Accreditation No. 200699-0). A copy of the laboratory’s accreditation is included as Appendix B. The laboratory was instructed to analyze samples from each homogeneous area until the first sample containing asbestos was identified. 4.1.3

Asbestos Analytical Results

Laboratory analysis confirmed the presence of ACMs including wall/floor joint caulk, replacement expansion joint caulk, cementitious panels, door caulk and asphalt shingle debris. A summary of the classification, condition and approximate quantity of identified ACM are presented in Table 2. A copy of the laboratory analytical report is included as Appendix C.

LEAD PAINT INSPECTION

Mr. Boucher, a GZA Industrial Hygienist, performed lead paint sampling on April 7, 2015. 4.2.1

Lead Paint Survey

The lead paint assessment included a pre-renovation/demolition lead paint survey at the Site building. The Occupational Safety and Health Administration (OSHA) survey was performed to assist in achieving compliance with the United States Department of Labor OSHA Lead Exposure in Construction Standard (29 CFR 1926.62), and USEPA Hazardous Waste Disposal Regulations (40 CFR Parts 260 through 271). The assessment was performed by collecting paint chip samples from representative accessible interior and exterior painted surfaces observed in and on the building designated to be impacted by the upcoming demolition plans and analyzing the samples to provide an indication of the presence of lead from testing combinations that were present to potentially create a lead hazard to workers in the course of the demolition of the building. The assessor scraped down to the substrate to remove all layers of paint on interior and exterior surfaces. Paint chip samples were collected in accordance with the sampling guidelines established in the US Department of Housing and Urban Development Guidelines for the Evaluation and Control of Lead-Based Paint (LBP) Hazards in Housing, Chapter 7 revision of 1997. Samples were individually collected in re-sealable bags which were consolidated into sample delivery groups. Samples were double-bagged prior to shipment via courier for off-Site laboratory analysis accompanied by the sample recording sheets and COC documents. In total, five samples were collected and submitted for analysis. A summary of the paint samples are presented in Table 3. 4.2.2

Lead Paint Sample Analysis

EMSL of Cinnaminson, New Jersey analyzed the paint samples for lead content using flame atomic absorption spectroscopy National Institute for Occupational Safety and Health Method SW 846 3050B/7000. EMSL is accredited for lead in paint analysis under the Environmental Lead Laboratory Accreditation Program (ELLAP Accreditation No. 100194). A copy of the laboratory’s accreditations is included as Appendix B. 4.2.3

Paint Analytical Results

Lead was identified to be present in four of the samples collected from the Site. As indicated in the attached results, the lead concentration in the sample collected from the yellow paint delineating the interior travel aisles was analyzed to contain greater than 0.5 percent in weight of lead content therefore is defined as LBP by the USEPA and the State of New Hampshire. The lead concentration in the samples collected from the interior floor lines (red) and exterior CMU walls and window trim were analyzed to contain less than 0.5 percent in weight of lead content therefore are defined as LCP. The lead concentration in the remaining submitted sample was below the detection limit, therefore is not defined as lead containing. Paint sampling results are presented in Table 3 and a copy of the laboratory analytical report is attached in Appendix D. 04.0190213.00

4.3

UNIVERSAL WASTES INVESTIGATION

Mr. Jeremy Boucher, a GZA Industrial Hygienist, performed the UW sampling on April 7, 2015. 4.3.1

Universal Wastes Assessment

During the site survey work, GZA conducted a visual survey of residual UW, potential PCB-containing components, and miscellaneous stored chemicals, petroleum products, and gases. UW, defined as 40 CFR Part 273 by the USEPA, includes hazardous wastes that are pesticides or electrical system components such as batteries, thermostats, and mercurycontaining lamps. Varying types of other hazardous materials present requiring proper disposal prior to renovation/demolition were identified in the Site buildings. With the exception of the sampling of sealant and caulk materials for the presence of PCBs, our inventory of hazardous materials was based on a visual assessment only; therefore, no sampling or characterization of wastes was performed. A detailed inventory, which includes the location and quantity of the hazardous materials, is presented in Table 4. The materials identified in Table 4 must be managed and disposed of in accordance with current State and federal hazardous waste management regulations. 4.3.2

PCB Sampling

During the investigation, GZA visually identified building sealants, caulking, and glazing suspected of containing PCBs. The assessment was performed by collecting bulk samples from representative accessible caulking, glazing, paints or sealants observed on the interior and exterior of the building, and analyzing the samples to provide an indication of the presence of PCBs in the materials that were present that potentially could create a hazard to workers during the course of the demolition of the structure. No samples of any adjacent materials was performed. Samples were placed in individual re-sealable plastic bags, wet wiped of visible debris, labeled with unique sample numbers using an indelible marker recorded and dispatched to an accredited laboratory for analysis following COC protocol. In total, five samples were collected and submitted for analysis for PCBs. 4.3.3

PCB Sample Analysis

ESS Laboratories (ESS), located at 185 Frances Avenue in Cranston, Rhode Island, analyzed the bulk samples for PCB content using gas chromatography USEPA Method 8082 using soxhlet extraction techniques, Test Methods for Evaluating Solid Waste. ESS is accredited for PCB in solid waste analysis, ELAP Accreditation No. 2864.01. 4.3.4

PCB Analytical Results

As indicated in the attached laboratory analytical results (Appendix E), the PCB concentration in the submitted interior gray expansion joint caulk sample was analyzed to contain greater than 50 parts per million. The PCB concentration in submitted black expansion joint caulk and the wall/floor joint caulk was less than 1 ppm of PCBs content. Please refer to Section 5.0 for hazard communication requirements that are applicable for these

materials. PCBs were not identified to be present in the remaining samples collected from the building. A sample summary which includes the location and quantity of the sampled materials, is presented in Table 5.

5.0 REGULATORY OVERVIEW 5.1

ASBESTOS

USEPA regulation 40 CFR 61, Subpart M, National Emission Standards for Hazardous Air Pollutants (NESHAPS) and the New Hampshire Department of Environmental Services (NHDES) regulate asbestos fiber emissions during renovation or demolition activities and asbestos waste disposal practices at both publicly and privately owned and operated facilities in the State. These regulations also require the identification and classification of existing building materials prior to demolition or renovation activity. Under NESHAP and New Hampshire regulations, asbestoscontaining building materials are defined as materials containing greater than 1% of asbestos content and are classified as either friable, Category I non-friable or Category II non-friable ACM. Friable materials are those that, when dry, may be crumbled, pulverized, or reduced to powder by hand pressure. Category I non-friable ACM includes packings, gaskets, resilient floor coverings, and asphalt roofing products containing more than 1% asbestos. Category II non-friable ACM are any materials other than Category I materials that contain more than 1% asbestos. Friable ACM, along with Category I and Category II non-friable ACM which is in poor condition and has become friable or which will be subjected to drilling, sanding, grinding, cutting, or abrading and which could be crushed or pulverized during anticipated renovation or demolition activities are considered regulated ACM (RACM). RACM must be removed prior to renovation or demolition activities that will disturb the materials. The owner or operator of a facility must provide the NHDES with written notification of planned removal activities at least 10 working days prior to the commencement of asbestos abatement activities. Removal of RACM must be conducted by a NHDES-licensed asbestos abatement contractor. Third party area air clearance air testing must be performed at the conclusion of the abatement activities and prior to re-occupancy of the removal areas. The OSHA Asbestos standard for construction (29 CFR 1926.1101) and general industry (29 CFR 1910.1001) regulates workplace exposure to asbestos. The OSHA standards requires that employee exposure to airborne asbestos fibers be maintained below 0.1 asbestos fibers per cubic centimeter of air as an 8-hour time weighted average. The OSHA standards classifies construction and maintenance activities which could disturb ACM, and specifies work practices and precautions which employers must follow when engaging in each class of regulated work. States which administer their own federally-approved State OSHA programs may require additional precautions.

5.2

LEAD PAINT

Lead is regulated by the USEPA, the State of New Hampshire, and OSHA. The USEPA and New Hampshire regulate the use, removal and disposal of LBP and OSHA regulates lead exposure to workers. The USEPA and New Hampshire defines LBP as paint, varnish, stain, or other applied coating that contains lead equal to or greater than 1.0 milligrams per square centimeter, 5,000 milligrams per kilogram, or 0.5% by dry weight as determined by laboratory analysis. For the purpose of the OSHA lead standard, lead includes metallic lead, all inorganic lead compounds, and organic lead soaps. The Resource Conservation and Recovery Act (RCRA) gave the USEPA authority to regulate the waste status of demolition or renovation debris, including lead-containing materials. Specific notification and testing requirements must be addressed prior to transporting, treating, storing, or disposing of hazardous wastes. Lead-containing wastes are considered hazardous waste under RCRA if Toxicity Characteristic Leaching Procedure results exceed 5 milligrams per liter. USEPA exempts from most RCRA requirements those generators whose combined hazardous waste generation is less than 100 kilograms per month. Detectable lead quantities may constitute a lead dust hazard during renovation/demolition activities. Personnel performing renovation/demolition activities that may disturb painted components with concentrations of lead above the designated analytical detection limit should comply with all current OSHA regulations in order to minimize employee exposure. OSHA defines LCP as a paint which contains lead, regardless of the concentration. Currently, any proposed renovation/demolition is subject to the OSHA regulations (29 CFR 1926.62 – Lead Exposure in Construction). The OSHA regulation defines specific training requirements, engineering controls, and working practices for construction personnel subject to this standard. Occupational exposure to lead occurring in the course of construction work, including maintenance activities, painting, alteration, and repairs is subject to the OSHA “Interim” Lead Exposure in Construction standard. Lead at concentrations greater than 50 micrograms per cubic meter (g/m3) averaged over an eight-hour period without adequate protection. The OSHA Standard also establishes an action level of 30 g/m3 which if exceeded triggers the requirement for medical monitoring. The above overview is not intended to be inclusive of all potentially pertinent regulatory information. The relevant USEPA, Massachusetts and OSHA standards should be consulted prior to undertaking activities involving the demolition, renovation, or maintenance of surfaces coated with lead paints. 5.3

UNIVERSAL WASTES AND PCB-CONTAINING MATERIALS

Universal wastes are regulated by the USEPA, the State of New Hampshire, and OSHA. The USEPA and New Hampshire regulate the use, removal, and disposal of UW and OSHA regulates exposure to workers. Universal wastes must be managed and disposed of in accordance with current State and federal hazardous waste management regulations. The USEPA’s Toxic Substances Control Act (TSCA) regulates the disposal of material classified as hazardous wastes. 40 CFR 761.62 of TSCA requires that caulks/sealants/glazing containing concentrations of PCBs of 50 parts per million or greater must be managed and disposed of as 04.0190213.00

Page 7

05/08/2015

PCB bulk product waste in a permitted solid waste landfill or by a completing a risk-based disposal process. Materials adjoining PCB-containing materials should be assessed and managed in accordance with state and federal regulations.

6.0 CONCLUSIONS Based on the results of the asbestos, lead paint and hazardous materials assessment detailed above, the following conclusions and recommendations are made: 

Due to the presence of ACM, LBP, LCP, and UWs identified within the Site building, GZA recommends that project-specific abatement bid specifications be developed for use in obtaining contractor pricing and developing construction sequencing;



Prior to conducting renovation or demolition activities impacting confirmed or assumed ACM, retain a State-licensed asbestos abatement contractor to remove ACMs;



PCBs were identified to be present in the expansion joint caulk samples collected from the exterior of the building. Prior to renovation, development of a PCB Work Plan is necessary in accordance with the Performance Based Option requirements of federal regulation 40 CFR § 761.61(b) for abating and managing PCB bulk product waste. Materials adjoining PCB containing materials should be assessed and managed in accordance with state and federal regulations;



Prior to conducting demolition activities impacting confirmed or hazardous materials, retain a qualified contractor to remove hazardous materials;



Notify contractors of the potential asbestos, LBP, LCP, and UW hazards per OSHA’s Hazard Communication rule (29 CFR 1910.1200); and



Universal wastes may either be removed and recycled, or disposed of in accordance with applicable state and federal regulations before demolition. If scheduled to be impacted and prior to the demolition work, the heating, ventilation and air conditioning units should be assessed to determine if the unit contain ozone depleting substances and, if present, the gas should be removed and collected from the unit using USEPA-certified technicians and approved equipment and procedures, and in accordance with the U.S. Clean Air Act.

APPENDIX A LIMITATIONS

LIMITATIONS 1.

GZA GeoEnvironmental, Inc.'s (GZA’s) asbestos/lead paint/hazardous materials evaluation was performed in accordance with generally accepted practices of other consultants undertaking similar studies at the same time and in the same geographical area, and GZA observed the degree of care and skill generally exercised by other consultants under similar circumstances and conditions. GZA's findings and conclusions must be considered not as scientific certainties, but rather as our professional opinion concerning the significance of the limited data gathered during the course of the asbestos/lead paint/hazardous materials evaluation. No other warranty, expressed or implied, is made. Specifically, GZA does not and cannot represent that the Site contains no asbestos-containing materials, hazardous materials, polychlorinated biphenyls or other latent condition beyond that observed by GZA during its asbestos/lead paint/hazardous materials evaluation.

2.

This survey report, which presents our findings, is not to be used as a bid document/work plan, or in place of a work plan, for conducting asbestos, lead paint, and hazardous materials abatement. When an asbestos abatement work plan is prepared, the State of New Hampshire recommends that a New Hampshire Department of Environmental Services-certified accredited Asbestos Project Designer prepare the plan. GZA recommends that a work plan be prepared and a bid walkthrough be administered by licensed GZA personnel familiar with the on-site asbestos conditions.

3.

The observations described in this report were made under the conditions stated herein. The conclusions presented in the report were based solely upon the services described therein, and not on scientific tasks or procedures beyond the proposed Scope of Services.

4.

The conclusions and recommendations contained in this report are based on limited environmental sampling and visual observations, and were arrived at in accordance with generally accepted standards of industrial hygiene practice. No other warranty, expressed or implied, is made.

5.

Where sample analyses were conducted by an outside laboratory, GZA has relied upon the data provided, and has not conducted an independent evaluation of the reliability of these data.

6.

The purpose of this report was to assess the physical characteristics of the subject Site with respect to the presence of hazardous materials in the Site building. No specific attempt was made to check on the compliance by any party with federal, State, or local laws and regulations.

7.

Observations were made of the Site as indicated within the report. While it was GZA's intent to conduct a thorough survey, it is important to note that we cannot guarantee that all asbestos, lead paint or potentially hazardous materials within the surveyed area have been identified. ACMs, lead paint, PCBs and universal wastes have frequently been where detection is difficult until renovation, demolition, and/or abatement work begins and allows access to these remote areas. Where access to portions of the Site was unavailable or limited, GZA has provided an opinion as to the likely presence of hazardous materials consistent with the information available. Suspect materials made accessible during demolition/renovation activities must be assumed to be hazardous and handled as such, until testing proves otherwise.

EMSL maintains liability limited to cost of analysis. This report relates only to the samples reported and may not be reproduced, except in full, without written approval by EMSL. EMSL bears no responsibility for sample collection activities or analytical method limitations. Interpretation and use of test results are the responsibility of the client. This report must not be used by the client to claim product certification, approval, or endorsement by NVLAP, NIST or any agency of the federal government. Non-friable organically bound materials present a problem matrix and therefore EMSL recommends gravimetric reduction prior to analysis. Samples received in good condition unless otherwise noted.
