1 Executive Summary

This document contains the Contaminated Land assessment developed for section 3 of the A5WTC scheme.

This volume is part of a set of 11 that form the Ground Investigation Report for this section of the A5WTC and should be read in conjunction with those other volumes.

Made ground was found intermittently along the route of the A5WTC scheme. Both made ground and natural soils were tested to identify any impacts on the reuse of material or disposal options of material declared unsuitable, along the route.

Soils were therefore considered with regard to their potential effects on detailed design, by impacting human health, local controlled waters, use as soft landscaping and potential disposal routes of any material declared as waste.

Both the greenfield and brownfield soils in section 3 are generally considered suitable for reuse. There is no identified chronic risk to human health and although exceedences compared to Salmonid river quality EQS’s were identified, as long as material is not used within 5m of a watercourse then there is deemed negligible risk from the soils to watercourses.

In terms of reuse as landscaping, 81% of the Greenfield material and all from the brownfield material was considered reusable without any precautionary requirements. Soil from the 19% of the Greenfield areas, providing it is used beneath the root growing layer, or appropriate tolerant species are used to accommodate the ground conditions of these soils, can also be reused.

Although the Greenfield material is considered suitable for reuse, should any material require disposal for any reason, then 94 % is considered suitable for disposal to an inert landfill facility, with the remainder suitable for a non hazardous landfill. In terms of the brownfield material 80 % is considered suitable for disposal to an inert landfill facility, with the remainder suitable for a non hazardous landfill. Overall, 92% of Section 3 is suitable for disposal at an inert landfill facility. Material that would attract hazardous waste criteria was not found.

There were concentrations of contaminants (boron, nickel and pH within the Greenfield areas and boron and sulphide within the brownfield areas) which may pose a risk to construction workers, but provided generic PPE and good hygiene practices are adhered to (as with any earthworks construction site) the risk from these contaminants to site staff will be negligible.

The principal pocket of brownfield land was soil deposited at Newtownsaville Bog and it would be prudent to obtain further sample for chemical analysis to determine the full extent of the contamination in this area.

2 Introduction

The proposed 88km A5WTC dual carriageway extends from New Buildings in Co Londonderry to Aughnacloy in Co Tyrone. To manage the construction, the scheme has been split into 3 sub sections:

Section 1: New Buildings to Sion Mills

Section 2 Sion Mills to South of Omagh

Section 3 South of Omagh to Aughnacloy.

A comprehensive introduction to the A5WTC scheme including the scope and objectives for the Ground Investigation Report (GIR) is provided in Volume 1, Chapter 2 of the GIR for Section 3.

To avoid the GIR becoming excessively voluminous and to ease readability, the report has been split into 11 sub-volumes. Volume 1 covers a general introduction to the scheme, the scope of the ground investigation works on site and general philosophy used in interpreting the investigation.

Volumes 2 to 9 breaks Section 3 of the scheme up into 8 geographical sub sections (sections 3A to 3H) and discusses the ground conditions found in each sub section. They also record the preliminary design recommendations for each sub section that have informed the specimen design of the preferred scheme that has been taken to the public inquiry.

Volumes 10 and 11 complete the set and each cover the whole section, discussing contaminated land and the geotechnical risk register.

This volume covers the contaminated land assessment for the whole of Section 3 of the scheme. The report is set out with headings compatible with the requirements of standard HD22/08. However, the bulk of chapters 1 to 3 are standard and are discussed in detail in the other volumes (1-9) and are not repeated here. Chapter 4 discusses the testing philosophy and test undertaken, 5 provides a summary of the ground conditions, and 6 the interpretation of the results, with recommendations in chapter 8.

3 Existing Information

A complete list of the sources of information which have been consulted in relation to the scheme is provided in Volume 1, Chapter 3 of the GIR for Section 3.

Section 3 was predominantly Greenfield, comprising 92% agricultural land, 7% peat bog and less than 1% urban/brownfield areas.

The following is a list of suspected contaminated sites (from N to S) that fall within or immediately adjacent to the draft vesting line. The initial rating is "relative" based on practical experience of degree of contamination typically found at such sites.

In section 3, the proposed scheme avoids impacting upon or from the landfill site at Tullyvar. However, small pockets of contaminated land are still expected to be encountered at the following locations: -

4 Field and Laboratory Studies

The scope of the ground investigation works are discussed in Volume 1, Chapter 4 of the GIR.

4.1 Chemical Testing Philosophy

Samples from the ground investigation were tested chemically for 3 reasons:-

 Soils within each section were assessed for suitability for reuse along the route of the proposed scheme whether as engineering or landscape fill. The intention was to reuse material in the works wherever possible. Therefore it must not pose an unacceptable chemical risk. Risk can be to humans, groundwater and surface water, ecosystems or property.

 To determine the method of disposal of any soils deemed geotechnically and/or chemically unsuitable for use in the scheme.

 At the location of areas of known or suspected contamination along the route, such as those areas identified as infilled quarries and landfills, where former industry had been present, or where flytipping had been identified. This was necessary to identify whether man made soils in those location would be chemically suitable for use or would require treatment prior to use, or disposal off site.

4.2 Basis of testing locations

The Greenfield areas (majority of the site) were tested for the chemical suitability of the soils to be reused in the proposed works. Within areas of proposed cut, the soils were sampled in each major strata at approximately 500m intervals along the route. No material was tested within the rock as this would be virgin material, suitable for reuse, whether on or offsite.

In proposed embankment areas, the top 1m of soils were sampled & tested to determine chemical suitability, as any soft surface soils in hollows in the ground may locally have to be replaced and relocated, prior to constructing the embankment. Again, a sampling frequency of 1 per 500 line metre was utilised.

Potential areas of contamination within the preferred corridor were identified as reclaimed land at Newtownsaville bog, landfill east of Aughnacloy and a site south of Aughnacloy that was previously used as a petrol station. Various localised areas of fly tipping, in addition to a number of backfilled quarries, are present, particularly south of Ballygawley. These areas were targeted during the ground investigation where they fell under the preferred route.

4.3 Testing suites

Within the Greenfield areas the following testing was undertaken:

For reuse – total soils metals suite (arsenic, boron, cadmium, chromium, copper, lead, mercury, nickel, selenium and zinc), pH and soils leachate potential testing for metals suite (as above), pH, nitrates, phosphorous and ammoniacal nitrogen.

Within the soils, where previous use indicated the potential for contamination the testing suites were based on the applicable DOE Industry Profiles, CLR8 where still relevant and associated guidance from the Environment Agency. Additional testing within Section 3 included:

 Soil analysis – ammoniacal nitrogen, asbestos screen, cyanide (total), speciated 16 PAHs, total phenols, sulphate, sulphide, semi volatile compounds (SVOCs), speciated total petroleum hydrocarbons (TPH), vanadium and volatile organic compounds (VOCs).

For waste the BS EN 12457-3 waste acceptance criteria testing to comprise 2 batch eluate (metals, phenols,and inorganics) and inert organic suite (Benzene, toluene, ethyl benzene, xylenes, PCBs, mineral oil, total PAHs and Total Organic carbon)

Within Section 3, 65 samples from 53 locations were sampled and analysed for reuse purposes. 11 of these samples were also obtained for specific contamination suites, identifying suitability for reuse, and/or waste disposal.

4.4 QA/QC

Samples were taken promptly from the exploratory holes with no cross contamination of strata, placed in appropriate containers (as supplied by the laboratory) and kept in a coolbox with cool packs, (or fridge) at 40C to prevent the loss of volatile components. Samples were then couriered to the laboratory for analysis with the testing schedule within 24 hours.

The soil samples were sent for the selected chemical testing at the independent laboratory, TES Bretby. This is an MCERTS and UKAS accredited laboratory.

Soil arisings obtained from all exploratory holes were examined visually, unusual odours were noted (where appropriate) and the appearance and type of soil was recorded and logged to BS5930 and BS EN ISO14688.

5 Ground Summary

5.1 Soil Descriptions

Volume 1 of the GIR provided background information for the entire Section 3 and includes details of sources of information which have been consulted and ground investigations which have been carried out in Chapters 3 and 4. An interpreted ground model is included in Chapter 5 of volume 1.

Chapters 5 & 6 of volumes 2-9 provide a summary of soil descriptions, geotechnical ground conditions and proposed design parameters for each sub section.

The geological long sections for section 3 of the scheme are shown on Drawing No. 718736 –D-0600- 30051. Soil tested came from the following settings:

 Glacial Sand and gravel and glacial sandy clay till;

 Isolated areas of peat

 Isolated areas of made ground.

For example, <1.0 mg/kg has been used as 1.0 mg/kg.

(2) Based on no known industrial uses of chromium VI within section 3 and that there is evidence of more elevated concentrations of naturally occurring chromium III within Northern Ireland than the UK it was considered that chromium III is the more likely component of the total chromium concentration. Therefore the results were re-screened against the GAC for chromium III

Mercury, PCBs and BTEX were not recorded greater than the limit of detection (LOD) of the laboratory apparatus in any of the samples obtained from Greenfield areas. Of the 17 PAHs only phenanthrene, anthracene, fluoranthene, pyrene, benzo(a)anthracene, chrysene, benzo(b)fluoranthene, benzo(a)pyrene, indeno(123-cd)pyrene and benzo(ghi)perylene were recorded above the LOD.

5.2.2 Made ground areas

These areas included those locations which were specifically targeted to a potential contamination source which had been identified either on the proposed scheme or at a distance which may impact the soils beneath the proposed scheme. These locations included the areas of flytipping and made ground particularly at Newtownsaville Bog and quarries and gravel pits backfilled with unknown material. Also the former railway embankment to the east of Aughnacloy.

6 Ground Conditions and Material Properties

As with chapter 5, the physical ground conditions and material properties are discussed in detail in volumes 2-9 of the GIR and are not repeated here.

The findings and interpretation of the environmental sampling is considered below.

6.1 Standards

At this stage, only a preliminary assessment has been undertaken using generic screening assessment values. The preliminary assessment is a conservative approach, which aids in identifying areas of potential contamination risk to receptors which may require further assessment. Therefore, an exceedence of a screening value at this stage, does not necessarily declare the material unsuitable. Where exceedences are noted a more detailed assessment of the risks posed to receptors, which would include using more detailed site specific data to obtain a more realistic screening value, would potentially render the material as reusable. However, this more detailed approach is for the detailed design stage of the works.

The chemical suitability standards used in assessing the suitability of materials for use in the scheme depend upon several different criteria, which are related to potential source-pathway-receptor linkages, which are:-

 Risks to the construction & maintenance staff

 Risks of exposure to users of the proposed road.

 Risks to controlled water

 Feasibility of use in landscaping areas

The flow chart in Figure 6-1 illustrates the decision making tree when applying screening standards and determining suitability or otherwise of materials.

For “greenfield soils”, mean concentrations are used as representative of the region. For brownfield soils, individual test results are used as specific to each site. If unexpected contamination is found it should be set aside, tested and treated as potential brownfield land.

Risk to construction workers was based on Health & Safety Executive guidance, listed in full in section 6.3.5. Long term chronic risk to site users follows NIEA/Environment Agency/SEPA guidance based around the CLEA v1.06 model and the following guidance:

 SR2 ‘Human Health Toxicological Assessment of Contaminants in Soil’, 2009

 SR3 ‘Updated Technical Background to the CLEA Model’, 2009

 SR4 ‘CLEA Model (version 1.06) Software Handbook’, 2009

 SR7 ‘Compilation of Data for Priority Organic Pollutants for Derivation of Soil Guideline Values’, 2008

 CLR11 ‘model procedures for the management of land contamination’, 2004

 Published Soil Guideline Values

 The LQM/CIEH Generic Assessment Criteria for Human Health Risk Assessment (2nd Edition), 2009

This latter document provides peer reviewed GACs (non governmental derived SGVs), and is accepted by the NIEA. With regard to long term human health, generic screening based on one of the four NIEA/EA standard end-uses (commercial end-use) has been carried out using SGVs where published and GACs derived by LQM/CIEH. No site specific screening values have been derived. This follows CLR11 guidance, where risk assessment progresses from preliminary to generic and onto detailed risk assessment, if the outcome warrants it, and there is site wide, man made contamination.

The risk to controlled waters is based on the Environmental Quality Standards for salmonid rivers. These were updated in 2008 by EU directive 2008/105/EC, and have been published within the Environment Agency guidance document ‘Horizontal Guidance Note H1 – Annex (d)’, 2010.

The reuse of materials in soft landscaping is based on the likely phytotoxic effects on herbage. The guidance on phytotoxicity is primarily related to food crops, thus is agricultural and sewage spreading based. The relevant documents are listed under the soft landscaping section.

6.2 Data Sets

As indicated in chapter 5, there are two distinct data populations in the chemical data set:

 Greenfield samples, which have effectively been randomly sampled to establish the statistical variation in their natural concentrations. These samples are assessed on the basis of mean concentrations; and

 Brownfield samples, which have been spot sampled to determine whether contamination hot spots exist at those locations.

These two data sets are considered separately in the following discussion.

6.3 Suitability of Greenfield Materials for Re-use

There is a sustainability aspiration, to maximise the re-use of material won on site and to minimise the need to import or export fill. Therefore, there is a presumption that material will be reused in the scheme unless proved geotechnically or chemically unsuitable. The chemical suitability criteria may however be more stringent in certain more sensitive locations as indicated below.

6.3.1 Suitability for Reuse near Water Courses

Some of the soils to be reused in the earthworks will be used near water courses. Many of the watercourses have been identified by the Northern Ireland Environment Agency as Salmonid rivers and thus are highly sensitive to natural or man-made contaminants. Soil leachate analysis was carried out and the findings compared against the Freshwater Fish Directive and Environmental Quality Standards.

A summary of the screening results where one or more samples exceed the EQS target are presented in Table 6-1 below and displayed in full in Appendix A.

718736-0600-R-008 Vol 10 A5WTC Section 3 S of Omagh to Aughnacloy Ground Investigation Report Environmental Testing Analysis

Table 6-1 Summarised results of EQS/FFD screening for reuse near water courses

Determinand Screening Range of Mean Exceedance Location Value (μg/l) concentrations concentration (μg/l) (μg/l) Arsenic 50 1 - 90 4.4 1 sample out of 48 (2%) TP3-2-016 Cadmium 0.08 0.1 – 0.9 0.14 100% of locations Copper 1 2 - 16 6.46 100% of locations Lead 7.2 1 - 26 4.69 9 samples out of 48 (19%) BH3-2-044A, BH3-2- 076, TP3.1.001, TP3.1.036, TP3-1- 058, TP3-1-082, TP3- 2-001, TP3-2-028, TP3-2-057 Zinc 8 13 - 188 46.4 100% of locations Mercury 0.05 0.1 – 0.3 0.12 100% of locations Selenium 1 1 - 3 1.14 4 samples out of 48 (8%) BH3-2-076, BH3-2- 079A, TP3-1-082, TP3-2-016

As described in the table above, all samples exceeded at least one EQS value. The stringent EQS values for cadmium, copper, zinc and mercury, meant that where soil leachate results were recorded greater than the feasible limit of detection (LOD) for these determinands, then the EQS was theoretically exceeded. In the instance of cadmium and mercury, the EQS was more stringent than the LOD, causing all locations to be greater than the EQS. Therefore, it was not considered appropriate to classify these soils as unsuitable for reuse based simply on the exceedences of these contaminants alone.

However, in practice, the practical earthworks standoff to construct bridges and culverts will generally be at least 5m, from the water course (when the use of concrete and structural stone fill for construction is taken into account) and therefore earthwork soils would not be placed within 5m of a watercourse. In the case of culverts, soil may feasibly be within 5m, however protection will be given by the low permeability concrete piping or steel culvert.

718736-0600-R-008 Vol 10 A5WTC Section 3 S of Omagh to Aughnacloy Ground Investigation Report Environmental Testing Analysis

Based on typical values from the geotechnical investigation (see volumes 2-9), the majority of strata encountered which could potentially leach to a watercourse is the glacial till which has a permeability of generally 10-7 m/s (occasionally 10-5 m/s where sandy/gravelly), a bulk density of around 2.3 g/cm3, and an assumed effective porosity of 0.2. The NIEA/Environment Agency calculations in the publication “Remedial Target Methodology: Hydrogeological Risk Assessment for Land Contamination”, 2006, allow estimation of travel times between a contaminant source and water receptor, and assuming the following soil water partition factors:

 Copper Kd 124 l/kg  Mercury Kd 500 l/kg  Zinc Kd 38 l/kg  Cadmium Kd 100 l/kg This gives rise to retardation rates of 38 (a unitless factor) and above. Therefore travel times to travel 5m, are in excess of 1000 years, and in the case of mercury in excess of 100,000 years. Therefore, these soils are considered suitable for reuse, provided they are not used within 5m of the watercourse.

As for the arsenic, lead and selenium exceedences, as a maximum (lead) only 19% of the samples tested exceeded the screening value. For both arsenic and selenium, only local exceedances were noted (one to 4 respectively) (2% to 8% of the overall analysis for those determinands). Therefore, these exceedences are considered isolated areas. When the mean of these contaminants was used (more representative of overall site conditions) arsenic, and lead do not exceed their EQS, and selenium only marginally, and that due to the high LOD1. Therefore, these soils are considered suitable for reuse.

Therefore providing that earthworks are not constructed within 5m of surface watercourses, the Greenfield soils won on site are considered suitable for use, with regard to protection of water quality.

1 Practice is that if a determinant is not detected, then its concentration is taken to be that of the limit of detection (LOD). This is a conservative approach, that tends to exaggerate mean concentrations of the data set. The actual concentration will be somewhere between 0 and the LOD.

6.3.2 Reuse where there may be Human Contact

Locally there may be potential for humans to come into contact with soft landscaping near lay-bys/settlements. Soil results were screened, following NIEA and Environment Agency guidance and the EA/DEFRA published “standard” end-uses. A commercial / industrial end use (adult) has been selected as the most appropriate given that it is lay-bys adjacent to a road that is being assessed. It should be recognised that this is very onerous, as the exposure period to potential contaminants will be for a much shorter duration i.e. stopping to change a wheel or for a rest break, not a 8 hour daily occurrence. The exposure considered includes dermal contact with bare soil, incidental ingestion and dust inhalation, plus inhalation of any volatile compounds that can be inhaled.

The mean and peak concentrations of all samples indicated these soils were suitable for this use. A summary of the screening results are displayed below and in full in appendix A.

The contaminant mean value for hexachlorobenzene appears to exceed screening values, however this is due to the laboratory limit of detection (LOD) being greater than the screening value. The LOD varies from 0.5 to 1.2mg/kg. It is likely that these contaminants concentrations would be below the screening value and are unlikely to pose a significant risk.

Looking at peak concentrations, the majority of the samples indicate that the soils are suitable for use, with 98% of the Greenfield samples suitable for use. No SVOC’s or VOC’s were detected. A summary of the screening results are presented in Table 6-2 below and displayed in full in Appendix A.

Table 6-2 Summarised results of CLEA screening for Human Health

Determinand Screening Range of Mean concentration Exceedance Location Value (mg/kg) concentrations (mg/kg) (mg/kg) Alkaline pH >9 6.2 – 9.1 7.96 BH3-2-038

Asbestos was not detected in any of the samples tested.

Only one sample exceeded the pH value and therefore should not be reused at ground level for human health reasons. The material comprised natural sandy gravelly clay, and therefore there was no discernible cause of the alkaline pH.

6.3.3 Reuse where there may be private water wells

There are a number of private wells along the route. Where the well is below the likely road construction, it will be decommissioned following Environment Agency Guidance ‘Decommissioning Redundant Boreholes and Wells’. This will occur if the well is close to the vesting line. Elsewhere, soil will not be moved or reused near water wells and as with water courses, the soil properties are such that potential contaminant migration over a distance of only 5m will take in excess of 1000 years.

6.3.4 Reuse as soft landscaping

Material may be suitable for use in soft landscaping areas, even if it does not meet the geotechnical requirements for use under the carriageway as engineering fill. Screening for phytotoxins is based on Statutory Instrument No 1263 ‘The Sludge (Use in Agriculture) Regulations 1989’ which relates to the spreading of sludge from domestic or urban waste waters or similar onto commercial food crop land. These do not relate to vegetable crops used for animal feed. ICRCL (still applicable for phytotoxins), notes that the principle phytotoxic elements are boron, copper, nickel and zinc, although recognises that at low concentrations these are essential for plant growth. All are believed to be phytotoxic at levels below the threshold for human health.

The mean concentration of all samples indicated these soils were suitable for this use. Looking at peak concentrations, 81% of the Greenfield samples were suitable for use. A summary of the screening results are presented in Table 6-3 below and displayed in full in Appendix A.

It is recommended the soil from the areas listed below is either not reused for landscaping, or if required, are contained at a depth below that of root growth, or consideration is given to species which are tolerant of the ground conditions of the soils from these areas.

 CH 82600 Feddan Road

 Off the proposed route, west of Tullywinny Road

 CH 66000 Tullyrush Road

 CH 66950 Rarone Road

 CH 67400 South West of Augher Point Road

 CH 71900 North of Routingburn Road

 CH 78500 East of Rarogan Road

6.3.5 Protection of Construction workers

The majority of the site is Greenfield, however health and safety is of paramount importance. Where contamination above background was noted, an assessment was carried out in general accordance with the Health and Safety Executive (HSE) document ‘Protection of Workers and the General Public during the Development of Contaminated Land’ (1991), Report number HS(G)66, plus ‘Guidelines for the Safe Investigation by Drilling of Landfills and Contaminated Land’, Thomas Telford (1993) and with reference to ‘A Guide to Safe Working on contaminated sites’, CIRIA Report 132 (1996).

Based on Appendix 2 of the HS(G)66, EH40/2005 and UK CLEA commercial screening values, the mean concentrations did not give cause for concern but there were specific potential health and safety implications in the following areas:

718736-0600-R-008 Vol 10 A5WTC Section 3 S of Omagh to Aughnacloy Ground Investigation Report Environmental Testing Analysis

Table 6-4 Summarised results of construction workers health and safety screen

Appropriate use of PPE within these areas will mitigate the risk posed by these soils to construction workers. Contaminants are at a concentration which can easily be mitigated by adopting safe working practices and good hygiene. As previously stated, there is no chronic risk associated with the Greenfield soils.

6.3.6 Summary of Greenfield samples

Having assessed the Greenfield soil data obtained against the relevant screening values to determine suitability for reuse based on risks to human health, watercourses, salmonid fish stock and plants, the following was determined.

 The Greenfield soils do not pose a chronic risk to human health and the potential short term health risks identified to site staff from a minority of Greenfield samples can easily be mitigated through appropriate use of PPE, safe working and good hygiene.

 81% of the Greenfield soils were deemed suitable for reuse for landscaping purposes. The locations from which soils are not deemed suitable for landscaping purposes or should not be used at the surface in proposed landscaped areas were BH3-2-057, TP3-1-062, TP3-1-001, TP3-1-015, TP3- 1-017, TP3-1-019, TP3-1-006, TP3-1-007, TP3-1-032 and BH3-2-038. Alternatively, species tolerant to slightly enriched Nickel should be adopted.

718736-0600-R-008 Vol 10 A5WTC Section 3 S of Omagh to Aughnacloy Ground Investigation Report Environmental Testing Analysis

 Soil leachate concentrations of cadmium, copper, zinc and mercury were recorded across the length of Section 3 which exceeded water EQS values, with concentrations of arsenic, lead and selenium recorded in isolated areas within Section 3. However, based on the predicted travel times of these contaminants and/or the overall mean concentrations for these contaminants being recorded less than the EQS, so long as material is not placed within 5m of the watercourse (a practical standoff distance) this material will be suitable for reuse.

6.4 Brownfield Sites

A list of sites that were considered brownfield was provided in chapter 3 of this document. Based on the screening of the maximum concentrations only (as mean concentrations were not considered in the brownfield assessment as the sample locations were targeted) there was not a chronic risk posed to human health.

6.4.1 Reuse as soft landscaping

The mean and peak concentration of all samples indicated these soils were suitable for this use. 100% of the brownfield samples were suitable for use. A summary of the screening results are presented in full in Appendix A.

6.4.2 Risk to Site Staff and Landscape Assessment

In relation to short term risk to construction workers there were a number of specific potential health and safety implications in the following areas:

Table 6-5 Summarised results of construction workers health and safety screen

6.4.3 Risk to Controlled Water Courses

The suitability of the brownfield material for reuse near a watercourse is discussed below.

718736-0600-R-008 Vol 10 A5WTC Section 3 S of Omagh to Aughnacloy Ground Investigation Report Environmental Testing Analysis

As with the Greenfield samples, cadmium and mercury exceeded their EQS as the EQS was more stringent than the LOD for these contaminants. Copper and zinc were recorded greater than LOD in all the brownfield samples analysed and were all recorded greater than their EQS. As discussed in respect to the Greenfield soils, so long at these soils are not placed within 5m of the watercourse, they are deemed suitable for reuse.

Several contaminants were found within the Brownfield sites which pose a risk to construction workers and therefore suitable and appropriate PPE should be worn to protect workers from direct contact, ingestion and inhalation of the materials.

6.5 Requirements for Disposal of Unsuitable Material

Some materials arising from the works will be classified under the Specification for Highways Works as geotechnically unsuitable (class U1A) or chemically unsuitable (class U1B and U2) and those must be removed from the site and disposed of in accordance with the Waste Framework Directive.

Under European Council Directive (91/689/EC), known as the Hazardous Waste Directive, a list of all wastes, hazardous or otherwise has been compiled known as the European Waste Catalogue (EWC, 1994, Commission Decision 94/3/EC). This has subsequently been updated. A revised EWC was released in 2002 under Commission Decision 2000/532/EC. This commission decision has been amended in turn by Commission Decisions 2001/118/EC, 2001/119/EC and 2001/573/EC.

718736-0600-R-008 Vol 10 A5WTC Section 3 S of Omagh to Aughnacloy Ground Investigation Report Environmental Testing Analysis

The Hazardous Waste Directive identifies three different classifications of waste, which require different disposal routes. The relationship between these and the unsuitable classes in the Specification for Highways Works (Series 600) are summarised in table 6.7:-

Table 6-7 Comparison of Waste Classifications

Hazardous Waste Series 600 Class Required disposal EWC Category Directive Class route Inert U1A Any licensed landfill 17.05.04 site Logs, frozen, waterlogged soils, and others not meeting the requirements of classes 1-9 Non-Hazardous U1B Landfill licensed to 17.05.04 accept non-hazardous Samples failing the site waste chemical criteria Hazardous U2 Hazardous Waste 17.05.03 Landfill Soils failing the site chemical criteria and exceeding the EWC hazardous waste criteria.

Based on the EWC as published by the Environment Agency as ‘Hazardous Waste: Interpretation of the definition and classification of hazardous waste, second edition v2.1, Technical Guidance WM2’, 2008, and its recent technical note amendment, unsuitable soils can be classified as 17.05.03; “soils and stones containing dangerous substances”, with its classification based on threshold concentrations of the contaminants present. The natural material would be classified as 17.05.04 “soil and stones other than those mentioned in 17.05.03”, and will therefore be non- hazardous.

Any peat horizons were not tested as this is non-hazardous and can be recycled as class 4 and 5 fills.

Any tarmac is likely to be classified as 17.03.02 (bituminous mixtures) and as such is considered non-hazardous.

718736-0600-R-008 Vol 10 A5WTC Section 3 S of Omagh to Aughnacloy Ground Investigation Report Environmental Testing Analysis

Where made ground/brownfield was encountered and classified as 17.05.03, all threshold concentrations are laid out in the Environment Agency document ‘Framework for the Classification of Contaminated Soils as Hazardous Waste, version 1, July 2004’. Based on this framework, each contaminant is identified by the Table 3.2. of Annex VI of the CLP Regulation (1272/2005) as having risk phrases.

There is no obligation on a landfill operator to take the waste. The landfill operator is under obligation however to ensure that any waste accepted is appropriate to the site permit and compliant with Waste Acceptance Criteria (WAC). To carry out Waste Acceptance Testing, the organics are analysed as solid waste. However metals, inorganics and phenols are analysed as eluate. This means that only the leachable components are compared.

The results of the WAC comparison indicated that the majority of the Greenfield material if disposed of would be suitable to be disposed of at an inert landfill facility. Approximately 94% of the Greenfield material tested would be suitable for this type of disposal. The balance (listed below) had one or more chemicals above the inert WAC criteria and would therefore require a non-hazardous disposal route.

Table 6-8 Greenfield material potentially required to be disposed at a non hazardous landfill site

Location Location description WAC exceedence TP3-1-032 CH 71900 North of Routingburn Road Cr, Ni, Sb

BH3-2-091 CH 91700 North East of Caledon Road SO4

TP3-1-082 CH 90050 North West of Carnteel Road SO4

The brownfield samples were first assessed as to whether they would be classified as hazardous or non hazardous waste if disposal of this material was required. Based on the results of the assessment, which used the maximum concentration of all the brownfield samples, boron and pyrene were identified as potentially hazardous determinands. They are deemed as potentially hazardous due to their flammable properties. However, the concentrations observed means the likelihood of the material being flammable is negligible. Also in the instance of boron, the hazard is only from elemental boron. Therefore, the material was deemed as non hazardous.

718736-0600-R-008 Vol 10 A5WTC Section 3 S of Omagh to Aughnacloy Ground Investigation Report Environmental Testing Analysis

As the brownfield material was classified as non hazardous the material was also compared against the WAC for an inert landfill for its appropriate disposal option. If the material was below the inert WAC threshold then disposal to an inert landfill facility would be acceptable, otherwise disposal to a non hazardous landfill would be required.

With the exception of two locations, all the brownfield material was considered suitable for inert landfill disposal. Approximately 80% of the brownfield material tested would be suitable for this type of disposal. Those samples which exceeded the inert WAC values for one or more of the criterion, thus determining that the disposal landfill facility would be required to be a non hazardous landfill, are detailed below:

Table 6-9 Brownfield material potentially required to be disposed at a non hazardous landfill site

Location Location description WAC exceedence TP3-3-093 CH 75000 Newtownsaville Bog TOC, mineral oil, Ba and SO4 TP3-3-095 CH 75000 Newtownsaville Bog Ba

Overall, from the samples obtained along the route for both Greenfield and brownfield locations, if offsite disposal was required, approximately 92% of the material along Section 3, if required for disposal, would be suitable to be disposed of at an inert landfill facility and the balance at a non-hazardous site.

The hazardous/non-hazardous waste assessment and WAC screening tables are presented in Appendix B.

718736-0600-R-008 Vol 10 A5WTC Section 3 S of Omagh to Aughnacloy Ground Investigation Report Environmental Testing Analysis

7 Geotechnical Risk

An overall Risk Register has been established for the scheme and used to inform the project management, the specimen design, safety & environmental management and in particular the project budget.

A geotechnical risk register for the proposed scheme has been established in volume 11 of the ground investigation report.

From the risk register, the following headline risks are potentially present within section 3

 Risks to human health from chemicals in the soil

 Risks to groundwater and surface water from chemicals in the soil

 Cost of disposal of any hazardous wastes

 Risk to concrete in the ground from sulphates

Of these, sulphates are addressed in the other subvolumes of the ground investigation report and are not reiterated here. The chronic risk to human health has not been revealed and is not considered further. Some minor risks associated with reuse near a watercourse, reuse for landscaping and protection of construction workers have been revealed and preliminary recommendations are discussed in chapter 8. There has been no hazardous waste material identified within Section 3.

The only areas which may require further assessment and investigation are

 the area of a former petrol station to the south of Aughnacloy if this area is required for vesting,

 landfill to the east of Aughnacloy

 former railway embankment also located to the east of Aughnacloy

 dumped soils at Newtownsaville Bog.

8 Preliminary Recommendations

8.1.1 Re-use of greenfield soils in the construction works

Greenfield soils in section 3 are generally considered suitable for reuse. There is no identified chronic risk to human health and although exceedences of salmonid freshwater EQS’s were identified, as long as no material is used within 5m of a watercourse then there is deemed negligible risk from the soils to watercourses.

In terms of reuse as landscaping, 81% of the material was considered reusable without any precautionary requirements. The remainder, providing it is used beneath the root growing layer, or appropriate nickel tolerant species are used to accommodate the ground conditions of these soils, then these soils can also be reused. The precautionary measures would be required for soils from:

 CH 82600 Feddan Road

 Off the proposed route, west of Tullywinny Road

 CH 66000 Tullyrush Road

 CH 66950 Rarone Road

 CH 67400 South West of Augher Point Road

 CH 71900 North of Routingburn Road

 CH 78500 East of Rarogan Road

There were concentrations of contaminants (boron, nickel and pH) which may pose a risk to construction workers, but provided generic PPE and good hygiene practices are adhered to (as should be with any earthworks construction site) the risk from these contaminants will be negligible.

Although the Greenfield material is considered suitable for reuse, should any material require disposal, such as excess arisings, then 94 % is considered suitable for disposal to an inert landfill facility, with the remainder suitable for a non hazardous landfill. The majority (26%) of the non hazardous material was located within Section 3D, with Section 3A, 3B, 3E, 3F and 3G also containing areas of non hazardous material (6%, 19%, 17%, 6% and 6% of the total non hazardous material respectively).

The fact that some apparently enriched chemical concentrations has been found in greenfield soils should not necessarily be an indication of contamination, but merely that natural background levels are enriched in the region. Long term slurry and fertiliser spreading would account for nitrates and ammonia, while the underlying rocks associated with the Sperrins Mountains contain numerous mineralised veins which will result in naturally enriched metal concentrations in the glacial soils that are derived from them.

8.1.2 Classification of Brownfield Sites

As with the Greenfield soils in section 3, the soils from brownfield sites are also generally considered suitable for reuse and significant risks have not been revealed. There is no identified chronic risk to human health and although exceedences of EQS’s were identified, as long as no material is used within 5m of a watercourse then there is deemed negligible risk from the soils to watercourses. In terms of reuse as landscaping, all the material was considered reusable without any precautionary requirements.

The only area of soil (from the samples tested) which may pose a risk to construction workers was also from made ground at Newtownsaville Bog, but provided generic PPE and good hygiene practices are adhered to (as with any earthworks construction site) the risk from these contaminants will be negligible.

Although the brownfield material is considered suitable for reuse, should any material require disposal, such as excess arisings, then 80 % is considered suitable for disposal to an inert landfill facility, with the remainder suitable for a non hazardous landfill. The two locations where the material was classified as non hazardous were in Section 3D (Newtownsaville Bog).

8.1.3 Risks to Construction Staff

A slight risk to construction staff has been identified based on the risk phrases for the contaminants identified at the site. While this does not render that material unsuitable for use in the works, we recommend that good hygiene practices should be employed during construction work and coveralls and gloves worn as a minimum to prevent skin exposure and incidental ingestion. No consumption of food or smoking should occur without prior handwashing. If dust is encountered, dust masks should be worn.

Table 8-1: Contaminant risk phrases Nickel Boron Risk Phrase

R49 – May cause cancer by inhalation 

R43 – May cause sensitisation by skin contact 

R11 – Highly flammable 

R20/21/22 Harmful by inhalation, in contact with skin and if swallowed 

R36/37/38 Irritating to eyes, respiratory system and skin 

It should be noted that these are generic potential hazards associated with the contaminants identified as potential posing a risk to construction workers. The concentrations identified and the use of appropriate PPE (as should be worn on all earth works construction sites) as detailed above will reduce the risk to negligible.

The recommendations laid out in the HSE document HS(G)166 and CIRIA report 132 ‘A Guide to Safe Working on contaminated sites’ (1996) should be followed.

Asbestos was assessed within the made ground. No asbestos was identified. If asbestos is encountered in the made ground during construction please refer to Section 10 of Statutory Instrument (2002) No. 2675 of the Control of Asbestos at Work Regulations 2002. It is recommended that, should potential fibres be identified during works, then that element of the works should be suspended until laboratory testing has been carried out.

8.1.4 Further Assessment

The screening of the chemical results in relation to suitability for reuse near watercourses, was screened against reuse near a salmonid river, which is the most stringent of the EQS screening values. However, if the material is to be reused near a less sensitive coarse fish river, then less stringent screening values can be used to assess the material suitability for reuse at the watercourses.

As the contamination assessment was only a preliminary assessment, where areas of contamination have been identified at concentrations greater than their screening value, a more detailed assessment may be required. This can be undertaken as part of the detailed design of the scheme. The more detailed

assessment may include more use of site specific data and where applicable, particularly in Greenfield areas, statistical analysis of the data set.

Where contamination of brownfield sites has been indicated, (Newtownsaville Bog) further sampling and testing to delineate the extent of contamination is recommended.

Further analysis and assessment is also recommended of the following areas during construction if land is acquired in those areas:-

 the area of a former petrol station to the south of Aughnacloy if this area is required for vesting,

 landfill to the east of Aughnacloy

 former railway embankment also located to the east of Aughnacloy
