EXECUTIVE SUMMARY

Arc Environmental, Inc. performed a pre-alteration hazardous material survey at the Historic Sheriff’s House located within the First State National Historical Park (Site) to evaluate building materials likely to be impacted by planned renovation and/or construction activities. The Site is located at 211 Delaware Street in New Castle, Delaware. The survey was performed to evaluate the Site for the presence and assessment of suspect asbestos-containing materials (ACMs), lead-based paint (LBP), and inventorying of universal/regulated wastes. The survey was performed on November 26 through November 27, 2018.

During the survey, a total of 42 bulk samples were collected from 14 identified homogenous areas suspected of containing asbestos throughout the Site. Based on the findings of the asbestos survey, one

(1) of the sampled homogeneous materials were confirmed by laboratory analysis to be asbestos-containing materials. The confirmed ACM (cementitious ceiling panels) is located within the exterior mechanical room. Additionally, three suspect materials, including the roof matrix, grey roof caulk and white roof caulk, were presumed to be asbestos-containing; the assumed ACMs were not sampled due to inaccessibility and/or based on an effort to maintain the integrity of the material. Section 2.0 of this report discusses in detail the asbestos survey and findings.

The lead-based paint survey was conducted at the Site using a portable X-ray Fluorescence (XRF) device for screening to determine if LBP was present at the site. Testing revealed that lead-based paint was present on interior components including: wood window components, wood baseboard, wood door components, plaster and concrete walls, wood wall trim, wood wall spindle, wood corner table/shelf, wood transom, wood wainscoting, wood shutter door, wood bathroom stall partition, wood riser trim, plaster column, wood closet shelf and walls. Lead-based paint was present on exterior window. Section

3.0 provides detail regarding the LBP survey.

Visual inspection was performed to identify and quantify Universal and regulated wastes associated with the Site. Potentially regulated and/or Universal wastes inventoried include potentially mercury-containing fluorescent tubes and potentially polychlorinated biphenyl (PCB)-containing ballasts. Section 4.0 provides details regarding the universal and regulated waste survey

Pre-alteration Hazardous Material Survey First State National Historical Park, Rehabilitate Historic Sheriff’s House December 28, 2018

1.0 Introduction

Arc Environmental, Inc. of Baltimore, Maryland, was retained by GWWO Architects to conduct a pre-alteration survey for hazardous materials at the Historic Sheriff’s House, located at the First State National Historic Park (Site). The Site is located at 211 Delaware Street in New Castle, Delaware. The inspection included the assessment and sampling of suspect, accessible asbestos-containing materials (ACMs) and testing of painted/coated building components to identify lead-based paint (LBP) along with a visual inspection to identify any universal/regulated waste. The findings of the survey are presented in this report. The survey was conducted by Arc Environmental on November 26 through November 27, 2018.

2.0 Asbestos-containing Materials Survey

2.1 Methodology

The asbestos survey included the identification, assessment, and sampling of suspect asbestos-containing materials. The survey was conducted under protocols established by the Environmental Protection Agency (EPA) 40 Code of Federal Regulations (CFR) 763 Asbestos Hazard Emergency Response Act (AHERA) and 40 CFR 61 Subpart M, National Emission Standards for Hazardous Air Pollutants

(NESHAP).

Every reasonable attempt was made to locate suspect asbestos-containing materials (ACMs) present as thermal system insulation (TSI), surfacing material, or other miscellaneous materials. Specifically, Arc Environmental employed the following protocols while performing the survey: flooring materials were penetrated to the subfloor to determine how many layers of flooring were present; wall systems and ceiling systems were evaluated to identify suspect building materials associated with the systems themselves, as well as any accessible cavities; and mechanical insulation systems were evaluated to identify potential suspect insulation beneath jackets and wraps. The survey was limited to accessible areas throughout the building and did not include roof sampling.

During the survey, a total of 42 bulk samples were collected from 14 suspect homogenous areas identified throughout the accessible portions of the Site. The bulk samples of suspect ACMs were submitted, along with the corresponding chain-of-custody forms to Scientific Analytical Institute, Inc. (SAI) to determine the presence of asbestos in the sampled materials. SAI is accredited for asbestos analysis in bulk materials through the National Voluntary Laboratory Accreditation Program (NVLAP). A copy of the laboratory’s NVLAP accreditation is included in Appendix A of this report.

The bulk samples were analyzed using polarized light microscopy (PLM/Dispersion Staining following the EPA method 600/R-93/116, Method for the Determination of Asbestos in Bulk Building Materials).

Based on the United States Environmental Protection Agency's (USEPA’s) definition, a material which contains greater than one percent (1%) asbestos, as determined using the methods specified in Appendix E, Subpart E, 40 CFR Part 763, Section 1, Polarized Light Microscopy (PLM), is considered an ACM and must be handled according to OSHA, USEPA, and the Delaware Department of Natural Resources and Environmental Control (DNREC).

2.2 Findings and Recommendations

Table 1 summarizes the data for Identified Asbestos-containing Materials at the Site. A copy of the chain of custody forms and Laboratory Analytical Results are included in Appendix A.

First State National Historical Park, A complete list of the building materials sampled during this survey is presented in Appendix B. It is recommended that if additional suspect materials not identified in this report are uncovered/exposed during demolition or construction activities, the materials should be assumed to contain asbestos or sampled and analyzed via PLM for asbestos content to determine if they are ACMs.

Table 1: Identified Asbestos-containing Materials

HA Description Location Total Quantity

TR1 Cementitious Ceiling Panels Exterior Mechanical Room Ceiling 320 SF

RM1* Roof Matrix Roof TBD

CK4* Grey Caulking on Roof Roof TBD

CK5* White Caulking on Roof Roof TBD

*Assumed material that was not sampled due to inaccessibility and/or to maintain the integrity of the material.

The roof matrix is considered a Category I Non-friable material. The EPA regulates Category I non-friable materials (resilient floor coverings, asphalt roof product, gaskets, and packings) when these materials have been rendered friable. Category I non-friable materials may become friable if subjected to sanding, grinding, cutting, or abrading. The Category I non-friable ACMs should be removed prior to disturbance if these materials will be impacted by planned activities at the Site.

The cementitious ceiling panels and various roof caulking are classified by the USEPA as Category II Non-friable materials. Category II non-friable materials are regulated if they have a high probability of becoming or have become crumbled, pulverized, or reduced to powder by the forces expected to impact the materials during the course of demolition or renovation activities. If these materials to remain in place and will not be altered during renovation activities, the materials can be managed in place.

The identified ACM(s) should be removed from the Site prior to renovations which may disturb the identified material(s). All abatement actions should be performed by personnel trained in accordance with USEPA, OSHA, and the DNREC for asbestos-related activities. In addition, a licensed asbestos consultant should be retained to conduct oversight and air-monitoring during any abatement activities.

In addition, if other suspect materials are encountered during demolition that may be impacted, these materials should be sampled and analyzed by PLM to verify asbestos content, or be assumed as ACM, prior to disturbance.

3.0 Lead-based Paint Survey

3.1 Methodology

Painted surfaces within the project area were visually inspected to determine their condition. A lead screening survey was conducted using an X-ray Fluorescence (XRF) Spectrum Analyzer on painted building surfaces and/or components. Surfaces that are intact or deteriorated condition (as defined by the U.S. Department of Housing and Urban Development Guidelines) do not pose an immediate health risk, First State National Historical Park, regardless of the lead content. Leaded paint in poor condition is a priority lead-hazard and should be promptly addressed using approved Lead Safe Work Practices.

The screening included field readings in addition to periodic calibration checks to ensure that the instrument is within acceptable calibration parameters. Lead-based paint, when tested via XRF, is defined by the U.S. Department of Housing and Urban Development (HUD) and the state of Delaware as paint having lead concentrations equal to or in excess of 1.0 milligrams per square centimeter (mg/cm²). The results of the lead-based paint survey are summarized in the XRF Lead-based Paint Inspection Data Sheets included in Appendix C.

3.2 Results

Of the 226 field screening shots, 108 of the XRF readings obtained from surfaces and coatings within the project area were found to contain lead in levels equal to or greater than the 1.0 mg/cm2 guideline for lead-based paint for DNREC. All of the XRF readings are detailed on the “XRF Lead-Based Paint Testing Data Sheets” attached to this report and are given in mg/cm2.

On the XRF data sheets, components described with a wall code of "A" are located on the closest wall with the same orientation as the front of the building. Components within each room are then assigned a letter B, C, or D in a clockwise manner based on the location of wall A.

3.3 ConclusionsandRecommendations

Components identified to be affected with lead-based paint or lead-based coatings include: wooden window casing, wooden window sill, wood window, wood baseboard, wood door casing, wood door trim, wood door, plaster wall, wood wall trim, wood wall spindle, wood corner table/shelf, wood transom, wood wainscoting, concrete wall, wooden shudder door, wooden bathroom stall partition, wooden riser trim, plaster column, wood closet shelf and plaster closet wall.

The OSHA Lead in Construction standard applies to all construction work where an employee may be occupationally exposed to lead. This standard does not indicate a specific percentage or mass per area (mg/cm2) of lead in paint that is permissible during construction/demolition activities. There is no acceptable concentration for lead under the OSHA lead standard that eliminates the requirement for contractors to comply with this regulation. Due to lead-based and lead-containing paint (paint containing detectable levels of lead but having concentrations below the lead-based paint threshold) associated with the Site, OSHA worker protection requirements for lead must be followed during renovation and/or demolition activities. It is recommended that a licensed lead abatement firm be utilized for any historical or non-historical components which may be intended to be stabilized or abated of lead-based paint through stripping, blasting, etc.

Building renovation and/or demolition activities have the potential to produce hazardous waste if lead-based paint is dry scraped, dry sanded, or heated. All renovation activities must incorporate lead Toxicity Characteristic Leaching Procedure (TCLP) testing of the construction debris prior to its disposal in accordance with the Resource Conservation and Recovery Act (RCRA). The hazardous waste criteria for lead waste is established under RCRA, Subtitle C, as 5.0 milligrams per liter (mg/L) measured with the TCLP as listed in CFR 40 Part 261. A representative sample of anticipated or generated waste stream (i.e., demolition debris) should be collected for purposes of TCLP testing to determine disposal options.

The lead-based paint debris generated during demolition should be handled in accordance with all applicable Federal and Delaware regulations.

First State National Historical Park,

4.0 Universal & Regulated Wastes

Arc Environmental conducted a visual inspection for Universal Wastes (UWs) and other potentially regulated and hazardous wastes within the project area. As per 40 Code of Federal Regulations (CFR) 261 Subpart C, UWs include any of the following six wastes that have at least one hazardous characteristic: batteries, pesticides, thermostats, cathode ray tubes, mercury-containing devices, and mercury-containing lamps (e.g., fluorescent tubes and high intensity discharge lamps). These wastes require proper handling and disposal methods when no longer in use or prior to completing any planned renovation/demolition activities. All identified Universal and potentially regulated wastes must be handled, transported, and disposed of in accordance with applicable regulations prior to the renovation of the Site.

4.1 Mercury

Arc Environmental observed 80 fluorescent tubes within the Historic Sheriff’s House. These fluorescent tubes are assumed to contain mercury. Mercury containing fluorescent tubes will require proper removal and disposal in accordance with USEPA regulations listed in 40 CFR Part 273.

4.2 PolychlorinatedBiphenyls

Arc Environmental conducted a visual inspection for PCB-containing light ballasts within fluorescent fixtures along with other potential PCB-containing equipment and material at the Site. If light fixtures containing ballasts were observed in the building, Arc personnel accessed the ballasts and recorded information from the manufacturer’s label. All capacitors and fluorescent light ballasts that are not labeled as “non-PCB” were assumed to contain PCBs. Arc Environmental observed 26 ballasts with the potential to contain PCBs. PCB ballasts will require proper removal and disposal in accordance with USEPA regulations listed in 40 CFR Part 273.

Although some of the ballasts may not contain PCBs, they likely contain other regulated liquids. Arc Environmental recommends collecting and separating all fluorescent light ballasts by type during the demolition process. The ballasts should then be characterized for disposal in accordance with federal, state and local regulations.

4.3 Other PotentiallyRegulatedandHazardousWastes

If other wastes are encountered during any renovation, or demolition activities, they will need to be removed and disposed of prior to any demolition activities due to the potential for releases incidences impacted the environmental. These other wastes will require proper handing, removal and disposal methods much like the UWs prior to any planned alterations or demolition at the Site.
