1. Introduction

AECOM was contracted by USACE to document the demolition of building 8832, located within Wetzel in Baumholder, Germany. As a part of this effort, AECOM was contracted to complete a hazardous materials (HAZMAT) survey to ensure that the demolition adequately protects the workers and to ensure that wastes are properly disposed of.

2. Regulatory Basis

2.1 Asbestos

2.1.1 FGS

The FGS Germany (2017) is the guiding document governing environmental matters for the US DoD in

Germany. The FGS provides three definitions that are relevant to the assessment of asbestos for this project:

Asbestos: Generic term used to describe six distinctive varieties of fibrous mineral silicates, including chrysotile, amosite, crocidolite, tremolite asbestos, anthophyllite asbestos, actinolite asbestos, and any other of these materials that has been chemically treated and/or altered.

Asbestos-Containing Material (ACM): Any material containing >1% asbestos by weight.

Friable Asbestos: Any material containing >1% asbestos that, when dry, can be crumbled, pulverized, or reduced to powder by hand pressure.

Occupational health requirements are not directly defined in the FGS. The FGS does require a notification and education program to tell workers, tenants, and building occupants where potentially friable ACM is located, and how and why to avoid disturbing the ACM. The FGS also requires that before disturbing or demolishing a facility or part of a facility, installations will remove all regulated ACM.

2.1.2 Germany and EU

In accordance with Technical Regulation for Hazardous Materials No. 519 Asbestos Demolition, reconstruction or maintenance work (TRGS 519, 2014, last amended 2019 /2./ materials are considered asbestos-containing when they contain one of the following silicates with fibrous structure: Actinolite, amosite, anthophyllite, chrysotile, crocidolite, tremolite. Asbestos-containing materials are to be separated under demolition, renovation or maintenance as defined under the special labor protection measures in accordance with the provisions of the Hazardous Substances Ordinance (GefStoffV) of

2010, last amended 2017 /8./ and TRGS 519 and disposed of properly. The scope of the required occupational safety measures depends on the type of asbestos product. In particular, it is important to distinguish between weakly bound (density less than 1,000 kg / m³) and tightly bound (density greater than 1,400 kg / m³) asbestos products. According to the TRGS, a risk assessment is required when working on asbestos-containing products.

Article 2(8) of the Hazardous Substances Ordinance (GefStoffV) /8./ defines occupational exposure limits (OEL) as the limit value for the time-weighted average concentration of a substance in the air at the workplace with respect to a given reference period. This OEL indicates the concentration of a substance at which acute or chronic adverse effects on the health of employees are generally not to be expected /7./. No OEL is currently defined for the majority of carcinogenic substances and none should be derived. The Council Directive 98/24/EC of 7 April 1998 on the protection of the health and safety of workers from the risks related to chemical agents at work, last amended on 26 July 2019 /15./, provides minimum requirements for assessing the risks to the health and safety of worker arising, or likely to arise, from the effects of chemical agents that are present at the workplace or as a result of any work activity involving chemical agents. In accordance with Article 8 of Directive 2009/148/EC of 30

November 2009 on the protection of workers against exposure to asbestos at work, last amended on

26 July 2019 /16./, employers shall ensure that no worker is exposed to an airborne concentration of asbestos in excess of 0.1 fibres/cm3 as an 8-hour time-weighted average (TWA).

In general, Annex II of the GefStoffV /8./ provides a ban on work on asbestos-containing parts. Only demolition, renovation, maintenance work (DRM-work) and activities with metrological monitoring are allowed. The associated expenses incurred in working with materials containing asbestos including waste disposal must also be accounted for. DRM work on asbestos-containing materials must be reported to the competent national health and safety authority at least 7 days before starting work.

2.2 Artificial Mineral Fibers

2.2.1 FGS

The FGS Germany (2017) does not address existing AMF. The US Occupational Safety and Health

Administration presently consider that “there is insufficient evidence that synthetic mineral fibers cause respiratory disease in humans. Results from animal experiments have led to conservative classifications of certain synthetic mineral fibers as possible human carcinogens. Specifically, insulation glass wool, continuous glass filament, rock (stone) wool, and slag wool are not classifiable as to their carcinogenicity to humans.”

(Source: https://www.osha.gov/SLTC/syntheticmineralfibers/health.html)

2.2.2 Germany and EU

Demolition, reconstruction and maintenance work concerning artificial mineral fibers (AMF) in Germany are regulated by TRGS 521 (demolition, renovation and maintenance work with old mineral wool) of

2008, not amended since publication /3./. For purposes of this regulation, "old" mineral wool is defined as being manufactured prior to 1996. A production and use ban for these products based on the

Hazardous Substances Act with implemented in 2000. In the years between 1996 and 2000, both "old" and "new" products were produced and used.

A carcinogenic potential is to be assumed for AMF products unless the manufacturer or user proves a different classification. This applies, for example, to the planned building removal of all not otherwise classified AMF products and commonly used as insulating materials, which were built before the year

1996. Due to lack of product data on some materials in the building, any unanalyzed AMF substances should be treated as carcinogenic. Where the RAL Certification Seal of the purchased material is available, this provides sufficient evidence of non-carcinogenic.

The future removal of the insulation during building demolition works must be carried out in accordance with the provisions of TRGS 521 /3./. In particular, the mineral fiber products are to be removed using low-dust methods and limit possible destructive break down AMF. The AMF must be disposed of separately from other waste. Measures must be taken to avoid the release of carcinogenic fiber dusts during storage and transportation. Waste, scrap and loose packages are to be collected and placed in appropriate containers (for example tear-resistant and dustproof bags) and labeled with the words

"content may release carcinogenic fiber dusts".

The Hazardous Materials Ordinance (GefStoffV) /8./ defines a carcinogenicity index (KI), for glass WHO fibers. The KI is a dimensionless quantity and is determined by the material composition of the analyzed mineral fibers in the insulation (or other) sample. It is calculated as the sum of the mass percentages

(in M %) of Sodium Oxide (Na2O), Potassium Oxide (K2O), Calcium Oxide (CaO), Magnesium Oxide

(MgO), Barium Oxide (BaO) and Barium Trioxide (B2O3) minus the double mass content of Aluminum

Oxide (Al2O3).

According to the GefStoffV /8./, glass WHO fibers, including the man-made mineral fibers (AMF), are classified with a KI as presented in Table 1:

Table 1. KI-Index Classification

Category Definition

KI < 30 – Category 1B Substances listed in Category 1B should be considered as carcinogenic to humans.

KI > 30 and < 40 – Category 2 Category 2 substances are materials of concern because of possible carcinogenic effect in humans.

KI > 40 – Category 3 Classified as non- carcinogenic

2.2.3 Classification of AMF for Building Rooms

In accordance with the above regulation, it is recommended for the building rooms that where RAL certification for the insulation material installed is provided or it is demonstrated that the material was installed after 2000, the material is considered non-cancer causing. In the absence of certification to the contrary, any material having a KI index result showing a “cancer-causing” designation will be considered “cancer-causing” and should be abated during the next renovation/demolition work in the associated room.

2.3 PAH – Poly Aromatic Hydrocarbons

Polycyclic aromatic hydrocarbons (PAHs) comprise a large group of compounds that consist of fused aromatic rings. Work in which workers are exposed to PAHs are to be classified as carcinogenic when a level of 50 mg/kg dry weight benzo(a)pyrene (lead compound) in accordance with §3(3) of the

Hazardous Substance Ordinance (GefStoffV) /8./Error! Reference source not found. in connection w ith TRGS 905 “Table of carcinogens” /6./ of 2016, last amended 2020 is observed.

In relation to work involving PAH-containing substances, this means that these operations take place in contaminated areas. The rules of the DGUV-R-101-004 (former BRG 128: Work in contaminated areas) of 1997, last amended 2006 and renamed 2015 /7./ apply. The release of dust when handling and decommissioning of PAH-containing or tar-containing materials must be prevented. The TRGS 551

("Tar and other pyrolysis of organic material") of 2015, last amended 2016 /5./ provides additional instructions for handling tar materials during the course of demolition and remediation measures.

Threshold limits for hazardous waste in Rheinland-Pfalz /25./: PAH > 1,000 mg/kg, Benzo(a)pyrene >

50 mg/kg.

2.4 PCB – Polychlorinated Biphenyl

The so-called PCB directive on the evaluation and remediation of PCB-contaminated construction materials in buildings of 1994 /14./ is currently being used to evaluate the remediation priority of PCB-containing components in buildings. The PCB Directive defines intervention values used in the context of construction safety law. The Directive contains standards for indoor air concentrations, remediation priority, rehabilitation implementation, disposal of PCBs and other aspects of dealing with PCB-contaminated construction products in buildings.

Guidelines have been prepared and put in place in several German states for the evaluation and remediation of PCB loads in buildings. The PCB contents in the buildings were assessed according to the PCB Guideline of Rheinland-Pfalz (PCB-Richtlinie des Landes Rheinland-Pfalz). Under these guidelines, substances with PCB levels above 0.1 mass% (1,000 mg/kg) are a potential primary source of PCB emission. Primary sources are products, which PCB were deliberately added to alter the product properties. Secondary sources are items in indoor air in which PCBs were released over a longer period from the primary sources. The detected PCB can also be issued from secondary sources over a longer period of time.

The "Regulation on the disposal of polychlorinated biphenyls, polychlorinated terphenyls and halogenated Monomethyldiphenylmethane" (PCBAbfallV) of 2000, last amended 2012 /13./ in conjunction with the European POP Regulation ("Regulation No. 2019/1021 of European-Parliament and the Council of 20. June 2019 on persistent organic pollutants"), last amended 2020 /17./ regulate the disposal of waste containing more than 50 mg/kg PCB.

PCB-containing paints or components require special work methods and safety measures. Dealing with the PCB-contaminated materials paints is classified as work in contaminated areas according to

DGUV-R101-004 and performed with the corresponding OSH regulations. This work should be defined in health and safety plan in accordance with DGUV-R-101-004 (former BRG 128: Work in contaminated areas) /7./ by the contracted entity.

2.5 Lead Paint

2.5.1 FGS

The applicability of the FGS is limited to child-occupied facilities as defined as Child-Occupied Facility:

A facility, or portion of a facility, visited regularly by the same child, 6 years of age or under, on at least

2 different days within any week, provided that each day’s visit lasts at least 3 hours and the combined weekly visits last at least 6 hours, and the combined annual visits last at least 60 hours. Child-occupied facilities may include but are not limited to daycare centers, preschools, playgrounds, and kindergarten classrooms. The buildings under this contract are considered a child-occupied facility.

Additional guidance to protect personnel from lead exposure is found under DODI 6055.1, “DOD Safety and Occupational Health (SOH) Program,” DODI 6055.05, “Occupational and Environmental Health

(OEH),” and concomitant Service instructions.

2.5.2 Germany

Lead-containing paint as well as lead containing material are regulated under the CLP Ordinance /25./ in Germany. According to Appendix VI, Table 3 of the CLP Ordinance, a building material is classified as lead containing when the lead concentration exceeds 0.03 mass% (300 mg/kg). Work on such building material shall be conducted in accordance with TRGS 505 “Lead” of 2007 /1./. Specifically, the technical regulations of TRGS 505 are to be observed when handling lead-containing materials. In addition, the workplace safety regulations of the DGUV-R-101-004 /7./ for work in contaminated areas must also be observed when working on components containing harmful substances. Additional information regarding workplace safety when handling heavy metal containing materials are presented in the TRGS 900 “Workplace Threshold Values” /22./ and TRGS 910 “Hazard based Action Plan for

Occupational Exposure to Carcinogenic Substances” (such as arsenic, cadmium and chromium VI)

/28./.

If construction material has to be removed and disposed of as waste, it has to be classified as hazardous wastes when the concentrations exceed the thresholds presented in Table 2 according to the Technical

Guidelines for Classifying Wastes according to their Hazards (Technische Hinweise zur Einstufung von

Abfällen nach ihrer Gefährlichkeit /26./) of the State Working Group Waste (Länder Arbeitsgemeinschaft

Abfall LAGA), of 9th February 2021. For heavy metals not included in this LAGA Guidelines such as mercury and total chromium, the state relevant regulations of Rheinland-Pfalz pertaining to classification of construction materials for disposal or reuse apply /25./.

3. HAZMAT Survey

The HAZMAT survey in building 8832 took place on 2nd November 2020. Building 8832 is a high voltage transformer building and an escort was required during the survey. The building has a simple structure and all relevant areas in the building were freely accessible. The building inspections and sampling were performed by experienced AECOM staff.

During the survey, 17 samples were taken and analyzed for their contaminant concentration. Analysis for Asbestos (4) was undertaken by the accredited laboratory Competenza GmbH. The analysis for

Heavy Metals (7), PAH (2), HBCD (2) and LAGA Debris (2) was undertaken by the accredited laboratory

Eurofins Umwelt West GmbH. A summary of the sampling results is provided in Chapter 4 below.

The sampling points were photographically documented and are presented in the floor plans in

Appendix A and additionally in a photo documentation Appendix B.

It is essential to note that a HAZMAT survey is, by its very nature, not exhaustive and minimally destructive. Building materials of similar construction and age are assumed to be made of the same material. Therefore, for purposes of this survey, if a sample returns a “positive” result, it is assumed that all materials (such as flooring, for example) of a similar nature are contaminated. Conversely, where the results show “negative” results, this is assumed to apply to all materials of a similar nature and age. Because the survey is not exhaustive, it is possible that areas not sampled because of their similarity to the areas sampled may have had different HAZMAT results, had they been sampled. A good example of this is mastic adhesive under carpeting. During a renovation project, the old mastic might not have been completely removed, but this would only become apparent if all the carpet were lifted during the HAZMAT survey. Thus, some asbestos-containing mastic might still remain undetected.

The laboratory reports for the current analysis are listed in Appendix C.

4. Results

4.1 General building description

Building 8832 is currently a high voltage electrical transformer building. It is a small structurally simple building that consists of concrete slab, concrete load bearing walls as well as concrete interior division walls.

The building has a flat roof covered with a tar looking paper. The outside doors are fire - rated doors.

The door frames are predominantly made from metal. The building does not have any window; several ventilation grids were installed on the roof as well as above the main door instead.

4.2 Survey results

The results of the laboratory analysis, as well as the results of the visual inspections, are shown in the following chapters separated according to the pollutant type.

In addition to the previously mentioned building containments, the presence of the following contaminated building materials or installations can’t be excluded:

- NH fuses in the electrical installations (or corresponding stocks) can be asbestos-containing.

As a HAZMAT survey is, by its very nature, not exhaustive and minimally destructive, it is possible that contaminant-containing materials exist in inaccessible building parts. If potentially contaminant-containing materials are found during the demolition work, current regulations must be checked whether they can be removed and disposed in accordance to current health and safety guidelines or if they can remain in the building.

Figure 1: Building 8832

4.2.1 Asbestos

The asbestos survey was carried out in accordance with the TRGS 519. Four samples were collected during this HAZMAT Survey and analyzed for asbestos fibers. The result of the survey regarding asbestos containing building material is presented in Table 3 below. The detection limit of all samples was 0.001%. For sample locations and photos, see Appendix A and B, respectively.

BH84-8832-AS4 27.08.2021 Roof Tar paper No asbestos detected

Font "bold" printed: proof or suspicion of the pollutant

According to the analytical results, asbestos was not identified in the sampled building materials.

However, the presence of asbestos is suspected in the fire door, manufactured prior 1990, at the main access to the building. It is also possible that the tar paper on the roof contains asbestos.

4.2.2 Artificial Mineral Fibers (AMF)

No samples were collected and analyzed for AMF in the course of the survey conducted on 2nd

November 2020.

As a HAZMAT survey is not exhaustive and minimally destructive, it is possible that AMF-containing materials exist in inaccessible building parts. In this case, examples would be insulating materials in the area of door connections or windows. If potentially AMF-containing materials are found during the demolition work, they should be considered “old” mineral wool if the manufacturing year can’t be determined.

4.2.3 Polycyclic aromatic hydrocarbons (PAH)

A tar paper layer was observed at the flat roof of the building and two samples were collected and analyzed for PAH (BH84-8832-PAH-1 and PAH-2) results of which are presented in Table 4.

In addition, as a HAZMAT survey is not exhaustive and minimally destructive, it is possible that PAH-containing materials with a Benzo(a)pyrene content above 50 mg/kg exist in inaccessible building parts.

Threshold limits for hazardous waste: PAH > 1,000 mg/kg, Benzo(a)pyrene > 50 mg/kg.

4.2.4 Polychlorinated biphenyl (PCB)

No sample was collected and analyzed for PCB in the course of the survey conducted on 2nd November

2020.

At the time of the HAZMAT Survey, a total of three transformer units were observed in building 8832.

Two of these electrical devices contain PCB oils. Redundant transformers containing PCB shall be removed from the site as complete load, i.e. together with the oil content to be transferred to a specialized site where the extraction of the PCB oil can be undertaken safely.

Products are considered PCB-containing if they contain at least 50 mg/kg of PCB.

4.2.5 Heavy Metals

As part of the building survey on 2nd November 2020 seven paint samples were collected from wall, floor and door and analyzed for heavy metals. The results of the laboratory analysis are presented

Asbestos

A total of 4 samples of plaster, mortar and tar paper from the flat roof were collected by AECOM at

Building 8832 in 2021. None of the samples revealed the presence of asbestos.

The potential asbestos containing fire door was not sampled, to keep destruction to a minimum, but is classified as asbestos-containing because of the building year of the building (before 1990). It is also possible that the tar paper on the roof contains asbestos. As asbestos-containing components in the above-mentioned materials cannot be excluded, employed personnel or other persons requiring protection should not be put at risk by hazards and should be reduced to a minimum during the dismantling work of the contaminated materials.

A common procedure for removal of asbestos-containing fire door is to remove the flange in one piece, seal it and transport it to a black zone (often outside of the construction site, e.g. to a place of the remediation company). There the asbestos-containing materials can be removed.

The occupational safety measures are included in the “regulations for safety and health protection when working in contaminated areas” (DGUV-R-101-004) and the technical rules regarding protective measures for activities related to asbestos containing material are presented in the TRGS 519 /2./.

If asbestos-containing products are encountered in non-accessible areas during the renovation, the requirements of the TRGS 519 (guideline for works with asbestos products) apply.

AMF

No samples were collected and analyzed for AMF.

As a HAZMAT survey is not exhaustive and minimally destructive, it is possible that AMF-containing materials exist in inaccessible building parts. In this case, examples would be insulating materials in the area of door connections or windows, between walls of dry wall, or sound impact insulation under screed or insulation on the exterior façade. If potentially AMF-containing materials are found during the demolition work, they should be considered “old” mineral wool if the manufacturing year cannot be determined.

If it is necessary during the renovation process, the future removal of the insulation must be carried out in accordance with the provisions of TRGS 521 (/3./) In particular, the mineral fiber products are to be removed using low-dust methods and limit possible destructive break down of AMF.

Heavy Metals

Seven samples of wall paint were collected and analyzed for heavy metals. Three samples presented lead concentrations above the threshold values defined by the CLP Ordinance for lead /27./. In addition, one samples revealed elevated zinc concentrations above the threshold values for hazardous wastes according to Table 2. The guidelines and relevant statutes for lead are found in chapter Error! Reference s ource not found..

Working with components that might contain lead as part of the demolition shall be considered as work with Hazardous Materials in accordance with TRGS 505 and the work must be carried out in accordance with the provisions of TRGS 505 (/1./), TRGS 524 (/4./) and DGUV 101 004 (/7./)).

PCB

Two samples were collected by WPW and analyzed for PCB. No PCB concentrations above analytical detection limits were identified. Therefore, no PCB containing material was identified at Building 8832.

PAH

Two Samples were collected from the Tar paper on the flat roof of the building and analyzed for PAH.

However, the results of both samples do not exceed the threshold limits for hazardous waste.

In general, work with PAH-containing materials must be carried out in accordance with the provisions of TRGS 524 (/4./), DGUV-R 101-004 (/7./) and TRGS 551 (/5./), if threshold limits for hazardous waste

(PAH > 1,000 mg/kg, Benzo(a)pyrene > 50 mg/kg) are encountered during demolition work.

HBCD

Styrofoam was identified at an inner wall of Building 8832; two samples were collected and analyzed.

The HBCD concentrations were below detection limit. Therefore, no HBCD containing material was identified at Building 8832.

LAGA

Two samples were collected from mineral construction materials from wall and floor slab. Results are presented in Appendix C.

6. Waste Codes

Table 9 shows contaminant-containing building materials, that can be expected in a dismantling measure, with the corresponding waste codes according to the German Abfallverzeichnis-Verordnung

(AVV /18./).

Waste codes marked with a "*" is always considered hazardous waste in the sense of the German AVV.

8. Limitations

AECOM has prepared this report for the sole use of USACE and USAG Baumholder in accordance with the Agreement dated 10 Sept 2020 under which our services were performed.

No warranty, expressed or implied, other than expressed in the Agreement, is made as to the professional advice included in this Report or any other services provided by us. Unless otherwise stated in this report, the assessments made assume that the sites and facilities will continue to be used for their current purpose without significant change.

The conclusions and recommendations contained in this report are based upon information provided by others and upon the assumption that all relevant information has been provided by those parties from whom it has been requested. Information obtained from third parties has not been independently verified by AECOM, unless otherwise stated in the report.

The methodology adopted, and the sources of information used by AECOM in providing its services are outlined in this report. The field work described in this report commenced on December 2020 and is based on the conditions encountered and the information available at the site of investigation during said period of time. The scope of this report and the services are accordingly factually limited by these circumstances.

The report relates to the current state of the site or facilities of investigation only and does not take into account their future development (if any) unless any specific forecasts are made and expressly designated as such.

oooOOOooo

AECOM would like to thank you for the opportunity to work on this project. Please feel free to contact the undersigned, should you have questions regarding any of the issues discussed in this report.

The agreed services relating to hazardous materials in buildings were provided by qualified AECOM employees on the basis of the documents and information provided by the client, taking into account the German and European legal framework, the German Technical Guidelines on Hazardous

Substances (TRGS) as well as the asbestos and PCB directives, assuming correct professional procedure.

In the course of a systematic site examination, the extent of which was defined and agreed upon beforehand, samples were taken of substances which in our judgment appear likely to contain hazardous materials; these samples were taken and analyzed for their hazardous substance content by an accredited analysis laboratory authorized to perform this task.

It cannot be excluded that further hazardous building materials may be found in areas of the site which were not accessible to or made accessible to us in the course of this project or in areas which, according to information provided by you or from a technical point of view, do not contain hazardous materials, or in areas, respectively, in which the existence of hazardous building materials is not immediately recognizable.

Additionally, it cannot be excluded that, as a result of severe fluctuations in the concentration for hazardous substance of a material, samples taken for analysis do not represent the average content.

The results of our survey can only apply specifically to the materials investigated as part of this survey.

Similar materials or materials which appear to be similar, which are located elsewhere may display different characteristics, e.g. in terms of hazardous substance content, even though they may originate from the same manufacturer, have the same identification, or display visual similarity. For the reasons mentioned above, the HAZMAT investigation performed in this project can make no claim to absolute completeness.
