1. INTRODUCTION

Socotec Italia S.r.l. (“Socotec”) has been commissioned by Golder Associates S.r.l. (“Golder” or “Client”) to carry out the geotechnical, geophysical, topographic and environmental survey of the portion of Aviano

Air Base’s Area A1 that will be subject to the new Entry Control Point design and construction.

This document describes the work and presents the results of the environmental survey conducted between June 11th and 17th, 2020 together with the results of the chemical testing of the soil samples and potential hazardous materials collected.

All activities have been performed in compliance with the Client’s sampling plan and the applicable Italian

Environmental Laws, in particular Legislative Decree n. 152/06 - Part IV and its amendments.

2. SITE OVERVIEW

Aviano Air Base is located in the Friuli-Venezia Giulia Region, Northeast Italy. It is comprised of nine geographically separated areas, eight of which are indicated in Figure 1:

Figure 1 – Aviano Air Base areas

P a g . 4 | 22

A new Access Control Point will be built in Area A1, in the proximity of the current Gate 1 access point

(Figure 2). The project includes demolition of existing buildings and construction of new ones, roads, pedestrian pavements and facilities. For this reason, preliminary environmental monitoring has been planned.

Figure 2. A1 area: project plan of the new Access Control Point around Gate 1

Buildings with offices and equipment rooms, parking lots and green areas are present around Gate 1 in

Area A1. The applicable environmental Italian regulation to the project site is Legislative Decree n. 152/06.

Considering the type of activities performed at the site, the applicable limits for soil contamination are those listed in Part Fourth, Title V, Annex 5, Table 1, Column B: commercial and industrial use.

Based on the Client’s sampling plan, Socotec survey covered the following zones of Area A1 (see Figure

3):

Green and paved areas the Gate 1 area;

Building 103, ground floor and first floor;

Building 106.

P a g . 5 | 22

Figure 3. Area A1, Gate 1: area object of the environmental and HazMat survey (red line)

3. SAMPLING

Socotec collected a total of 26 soil samples from the seven (7) soil borings S1 to S7 drilled in the green and paved areas near Gate 1 and a total of 17 samples from potentially hazardous materials ("HazMat") from Buildings 103 (only inside samples) and 106 (both inside and from the outside samples).

3.1 Soil samples

As required by the Client, Socotec carried out the following investigation plan:

Three (3) continuous coring boreholes drilled until 10 meters depth, inclusive of Standard

Penetration tests ("SPT") and geotechnical and environmental sampling (green dot in Figure 4);

Four (4) continuous coring boreholes drilled until 3 meters depth, inclusive of SPT tests and geotechnical and environmental sampling (red dot in Figure 4).

The boreholes locations are indicated in Figure 4 below.

P a g . 6 | 22

Figure 4. Boreholes location

The results of the geotechnical sampling and analysis are described in the specific report and will not be discussed in this document.

Soil cores were placed in plastic boxes, following the natural stratigraphy. For each sample, using a stainless scoop, Socotec collected 8-10 punctual portions of the core soil, to create a composite amount of soil intended for analysis of volatile parameters. This amount of soil was stored in an airtight glass 200 ml volume container, filled to the brim and rapidly closed, taking care to minimize the disturbance of the sample and the loss of the volatile components.

Socotec collected also 10 increments per sample intended for non-volatile parameters analysis. The soil was passed through a 2 cm sieve, collected in a clean bucket, well-homogenized, and finally stored in a

800 ml volume airtight glass container.

Each containers was labeled, specifying the sampling point location, name of sample and depth. Socotec prepared a chain of custody with the date, name of technician, matrix and sample id.

P a g . 7 | 22

All sampling devices were washed with clean fresh water and decontaminated with distilled water solution after each sample collection.

Samples were stored in a portable fridge and maintained at 4°C until arrival at the laboratory.

The list of soil samples collected is provided in Table 1 below.

3.2 Hazardous materials

During the HazMat survey, a total of 17 potential HazMat samples were collected from Building 103 and

106 (see Figures 5-6-7) of various potentially hazardous materials, to determine:

Presence of asbestos containing material (ACM);

Presence and characteristics of man-made vitreous fibers (“MMVF”);

Presence of heavy metals, PCB, mercury.

P a g . 10 | 22

Figure 7. Plan of potential HazMat samples location in Building 106

Samples collection was undertaken after laying a tarp near or under the sampling area to minimize the spread of potentially contaminated particles, and, using pliers or a spatula, removing a small amount of the item to be investigated. Samples were stored in double polyethylene bags, well-closed and labeled.

ACM and MMVF samples were fixed with special transparent sealing paint spry to minimize fibers dispersion and the sampled location, when possible, was covered with sealing tape.

After sample collection, Socotec filled out the relative chain of custody for laboratory analyses.

The list of the potential HazMat samples collected from Buildings 103 and 106 during the survey, is provided in Table 2:

All the collected samples results did not exceed the Italian DLgs 152/05 regulatory limits with the exception of samples S2CA2 (1-2 m) and S2CA3 (2-3 m), showing exceedance of the public, private, residential use and green areas (Column A) limit for Vanadium.

5.2 Hazardous materials

Concerning asbestos investigations, the main applicable Italian regulations are:

Law 27th March 1992, n. 257 - Rules on asbestos use ban;

Health Ministerial Decree 6th Sept 1994 - Regulations and technical methodologies for the application of art. 6, paragraph 3, and art. 12, paragraph 2, of the law of 27 March 1992, n. 257, concerning the halt of the use of asbestos;

Legislative Decree 81/08 –Workers Health and Safety Act.

The hazard of asbestos, classified as 1A Carcinogen, is due to the possible fibers dispersion in the environment that can be inhaled and have a cancerogenic effect on the lungs.

Table 6a-6b. ACM Samples: analyses results

None of the analyzed ACM samples shows the presence of asbestos fibers including the samples collected from the outside wall of Building 106. Such samples are constituted by a serpentine rock with a chrysotile-like composition without fibrous crystals and are all ACM-free.

Duplicate sample ACM10 showed the same analytical result of sample ACM09, confirming the quality of the results.

MMFV were investigated to determine fibers harmfulness according to the following regulation:

Regulation (EC) N° 1272/2008 of the European Parliament and of the Council of 16 December

2008 on classification, labelling and packaging of substances and mixtures, amending and repealing Directives 67/548/EEC and 1999/45/EC, and amending Regulation (EC) No

1907/2006;

MMFV Guidelines drawn up by the Italian State-Regions Conference (2016).

As with asbestos, the danger of the MMVF is related to the possible release of fibers that can be inhaled and cause lung cancer.

Table 7. MMVF Samples: analyses results

Socotec analyzed two pipes insulation MMVF: one in the boiler room in Building 103 and one in a duct inside Building 106. The MMVF sample collected in Building 103 resulted hazardous because of its fibers dimension.

No specific regulatory limits are defined in the Italian regulations regarding the presence of heavy metals in wall paints. However, pigments containing lead sulphochromate and lead sulphochromomolybdate were included in February 2012 in Annex XIV to the REACH Regulation

(Regulation (EC) N 1907/2006 of the European Parliament and of the Council of 18th December 2006 concerning the Registration, Evaluation, Authorization and Restriction of Chemicals.

6. CONCLUSIONS

6.1 Soil samples

Analyses results of the soil samples collected from the soil bores undertaken in Area A1 near Gate 1 comply with the regulatory limits applicable to Aviano AB for “sites with commercial and industrial use”

(Table 1, Column B, Annex 5, Part IV, of D.Lgs.n°152/2006), and no further action or investigation is required.

Even if not applicable to Aviano AB, the analyses results showed compliance even for the most restrictive Italian residential limits (Table 1, Column A, Annex 5, Part IV, D.Lgs.n°152/2006), with the exception of Vanadium in the two S2 samples collected between 1 and 3 m below ground surface.

6.2 Hazardous materials

As shown in table 6a-6b, no ACM sample analyzed show the presence of asbestos fibers, so no further activity is required.

From the available information Building 103 was completely renovated in 2007. The renovation date is later than the year in which the use of asbestos was banned in Italy (1992).

The ornamental stones used to decorate the outside walls of building 106, although they are made of green stones (serpentine), do not show fibrous crystals and therefore cannot release hazardous fibers.

Concerning the two MMVF samples of insulating materials, the analyses results show that:

103_113_FAV01 is constituted by “Man-made vitreous (silicate) fibers with random orientation with alkaline oxide and alkali earth oxide (Na2O+K2O+CaO+MgO+BaO) content greater than 18 % by weight”. The length weighted geometric mean diameter minus two standard geometric errors is less than 6 µm: applying the classification criteria of the CLP regulation (European Union

Regulation n. 1272/2008), and the 2016 Italian MMVF Guidelines drawn up by the Italian State-

Regions Conference, the sample is classified as carcinogenic 2.

106_2P_10_FAV05 is properly a “Refractory Ceramic Fiber”, made up of “Man-made vitreous

(silicate) fibers with random orientation with alkaline oxide and alkali earth oxide

(Na2O+K2O+CaO+ MgO+BaO) content less or equal to 18 % by weight”. The length weighted geometric mean diameter minus two standard geometric errors is greater than 6 µm: applying the

P a g . 22 | 22 note R1 of Annex VI of the Reg.1272/2008 and the 2016 Italian MMVF Guidelines, the sample is not classified as carcinogenic.

The 103_113_FAV01 sample was collected from the pipe insulation connected to the rear of the boiler called "103 A" (as shown on the boiler side), and it was marked on-site with red paint, as indicated in

Annex 1.

Italian regulations do not provide for the removal or disposal of MMVF if classified as hazardous.

However, to minimize the possible exposure of personnel and workers to airborne fibers during demolition and disposal activities, it is recommended to adopt the same approach used for ACMs according to the following approaches (from most effective to less effective):

Elimination of the risk (removal);

Minimization of the risk (enclosure, encapsulation, sealing);

Administrative controls (safe work practices such as regulation of access to the boiler room, including signs; appropriate information for personnel who must maintain and/or repair the equipment);

Using personal protective equipment;

Monitoring airborne fibers during maintenance work.

A combination of the measures above may be required to adequately manage and control the hazardous MMVF. Title IX of Italian Legislative Decree 81/2008 mandatorily requires to protect workers from hazardous substances risk of exposure.

The handling and eventual removal of the pipe insulation at boiler "103 A", has to be conducted implementing measures to avoid any fiber dispersion. The workers have to wear the correct health and safety protection means (such as FFP3 masks).

The waste generated by the removal has to be managed as dangerous waste.

About the wall paint sample “106_11_MET01”, analyzed for the evaluation of heavy metals concentrations, a significant concentration of lead (516 mg/kg) was detected. In case of demolition, all precautions should be taken and it is recommended to perform an environmental monitoring for dust dispersion.

1 Note R: The classification as a carcinogen need not apply to fibres with a length weighted geometric mean diameter less two standard geometric errors greater than 6 μm.
