1 Introduction and Site Setting

1.1 Terms of Reference

1.1.1 ECUS Ltd. (hereafter ECUS) was commissioned by Amber Valley Borough Council (in a letter dated 27th November 2007) to carry out a ground investigation in an area of land off Wyver Lane, Belper, Derbyshire and hereafter referred to as ‘the site’. The approximate National Grid Reference (NGR) for the site is 434410 350400.

1.1.2 A Phase 1 Site Investigation report was completed by ECUS (reference SM/076/070807/P1) in September 2007. A Phase 2 Site Investigation report was completed by ECUS (reference KL/76/080213/P2) in February 2008. Reference should be made to these reports for full details of the site and investigations undertaken.

1.1.3 Gas Monitoring has been undertaken on four occasions following the Phase 2 report and six occasions in total over a six month period. The results are detailed in this report, together with a gas risk assessment.

1.2 Site Location and Current Condition

1.2.1 Figure A1, Appendix A shows the location of the site. Figure A2, Appendix A shows the current layout of the site.

1.2.2 The site covers approximately 28 hectares and is situated north of the town of Belper to the west of the River Derwent. The site is an irregularly shaped parcel of land situated between Wyver Lane and the River Derwent, and is known to have a history of use as a landfill site.

1.2.3 Lawn Cottage stands at the centre of the northern end of the site and comprises a stone built detached house with domestic outbuildings. These include garages, workshops, a coal shed and two aviaries. A large garden area is present. The remaining land consists of approximately 12.5 hectares of grazing land and approximately 15 hectares of land and wildlife pond which constitute the Wyver Lane Pool Nature Reserve.

1.3 Proposed Development at the Site

1.3.1 This report is provided in preparation for development at the site. The development proposals are outlined below and it should be noted that the report gives comment in relation to those proposals. The conclusions drawn may have to be re-assessed should any change in the proposed end use be considered.

1.3.2 Figure A3, Appendix A shows the proposed site layout post purchase and initial development. A management plan for the site has been developed in line with the intended after-use. The site is divided into three parts, the North Field, the Southern Field and Lawn Cottage, which will remain as a key part of the development. The North Field will consist mainly of coppice woodland, a tree nursery and camping area, including a camping barn and a car parking area.

1.3.3 The Southern Field will consist of mainly of a hay meadow which will be managed as a conservation area by the local Wildlife Trust. An area on the most northerly part of the Southern Field will be used as an activity area.

1.3.4 Lawn Cottage will be retained as a residential building with gardens. This report has been produced with this end use in mind and any alteration to the development plans may result in a need for additional assessment.

2 Gas Monitoring

2.1 Installation of Gas Monitoring Wells

2.1.1 Four gas monitoring wells were installed during the Phase 2 site investigation in December 2007. The gas monitoring wells were installed within window sampler boreholes WS1, WS2, WS6 and WS7.

2.1.2 The locations of the window sampler boreholes are shown in Figure A5, Appendix A. The purposes of the gas monitoring wells are summarised in Table 1 below.

Table 1: Purpose of Gas Monitoring Wells

Borehole Purpose

WS1 To assess the risk of landfill gas to the proposed Camping Area.

WS2 To assess the risk of landfill gas to the proposed Bunk Barn.

WS6 To assess the risk of landfill gas migration to Lawn Cottage.

WS7 To assess the risk of landfill gas migration to Lawn Cottage.

2.2 Monitoring Timetable and Method

2.2.1 Gas monitoring has been carried out on seven occasions over seven months since the intrusive investigation.

2.2.2 Gas composition within the installation (methane (%v/v CH4 and %LEL (lower explosive limit)), carbon dioxide (CO2) and oxygen (O2)) is monitored using a Gas Data GSM430 portable landfill gas analyser. The anemometer function within the unit is also used to monitor the flow rate of gas within the monitoring well.

2.3 Gas Monitoring Results

2.3.1 Monitoring results from the seven monitoring visits are presented in Tables 1 to 6.

3 Gas Risk Assessment

3.1 Background

3.1.1 Recent guidance produced by CIRIA1 details good practice for the investigation, monitoring and assessment of the gas regime of a site. It advocates an approach that involves the calculation of Gas Screening Values (GSVs) which are calculated by multiplying the flow rate of gas by the percentage concentration of gas recorded. GSVs are calculated for both methane and carbon dioxide.

3.1.2 The calculated GSVs for a given site can subsequently be compared against a series of comparative values for which a ‘Characteristic Gas Situation’ has been assigned. For new build properties, this then corresponds to specific levels of protection that must be incorporated into the development.

3.2 Results Analysis

3.2.1 Table 9 presents the maximum recorded methane and carbon dioxide concentrations and flow results for each borehole, and calculates the GSVs for each borehole.

3.2.2 To assess the risks to each part of the development, the worst case GSV has been compared with the limits in the CIRIA guidance, in order to determine the appropriate Characteristic Situation.

3.3 Recommendations

Bunk Barn – Assessment using Data from WS2

3.3.1 The gas monitoring results from WS2 in the proposed Bunk Barn area place the site within Characteristic Situation 2 within the CIRIA guidance.

3.3.2 Recommendations given in CIRIA C665 for gas protection measures for a site within Characteristic Situation 2 site are as follows:

a) Reinforced concrete cast in situ floor slab with at least 1200g hydrocarbon resistant damp-proof membrane (DPM).

or

b) Beam and block or pre cast concrete slab and minimum 2000g DPM orreinforced gas membrane.

1 CIRIA Report C665. 2007. Assessing risks posed by hazardous ground gas to buildings.


KL/76/080331/GM June 2008

3.3.3 All services which penetrate through the DPC / membrane should be sealed so that the penetration point is gas-tight. The architect should provide details of the service entries.

3.3.4 If option b) above is to be adopted and a reinforced gas membrane is to be used instead of a 2000g DPM, the gas membrane should be resistant to radon, carbon dioxide, methane and hydrocarbon vapours.

Camping Area – Assessment using Data from WS1

3.3.5 Methane has been in borehole WS1 on four occasions. However, gas flow has not been detected on any occasion. There are to be no permanent structures in which methane can accumulate to within the explosive range, therefore campfires within raised braziers are considered acceptable.

3.3.6 No gas flow has been detected on any monitoring visit. Therefore, so long as all tents used in this area have impermeable groundsheets and have the normal degree of ventilation, the risks to campers from ground gases are considered to be acceptable.

Lawn Cottage – Assessment using Data from WS6 and WS7

3.3.7 The highest GSV for carbon dioxide is 0.15 l/h in borehole WS7. This places Lawn Cottage into Characteristic Gas Situation 2. Reference to the CIRIA guidance states that this category is ‘low risk’ and that the gas screening values and concentrations recorded are indicative of ‘typical made ground’, not for landfill gas.

3.3.8 If a new build was to be considered, the protection measures described within the Bunk Barn section above would be necessary. This is not possible within the existing building.

3.3.9 On the same monitoring occasion, there was no carbon dioxide, methane or gas flow recorded within borehole WS7. It is therefore considered that the source of the gas detected within borehole WS6 on 19th February was from the made ground adjoining Lawn Cottage in the area of WS6, and not the landfill mass.

3.3.10 It is considered that the made ground is unlikely to underlie the ground floor of Lawn Cottage. If the drive area adjoining Lawn Cottage is to remain surfaced with a permeable material such as the existing pea gravel, it is considered that gas generated from the made ground adjoining Lawn Cottage would preferentially migrate upward and vent to the atmosphere during times of low atmospheric pressure, as opposed to migrating into Lawn Cottage itself.

3.3.11 Based on the monitoring data available, landfill gas protection measures are not considered necessary for Lawn Cottage. If the prospective purchasers of Lawn Cottage remain concerned about carbon dioxide migration into Lawn Cottage, gas monitoring within confined spaces inside the building may be considered in order to demonstrate that build up of carbon dioxide is not occurring within the building.

Radon

3.3.12 The previous report indicated that the site is within a Radon Protected Area and that basic radon protection measures should be installed within new buildings (not old buildings such as Lawn Cottage). It is considered unlikely that Lawn Cottage will have specific radon protection measures.

3.3.13 It is therefore recommended that a radon test is undertaken to determine whether radon protection measures are required. This takes the form of a passive detector, usually one upstairs and one downstairs within the property. The detector is then analysed at a laboratory at the end of the monitoring period. Monitoring periods of 48 hours, 7 days or 3 months are available, with longer monitoring periods giving more certainty in the results.

FAO Mr. D. Hurst, Scientific Officer

Dear Darren,

Re: Groundwater and Surface Water Sampling: Site at Wyver Lane, Belper

We are pleased to report on the recent works as outlined above.

Introduction

ECUS Ltd previously produced a site investigation report for the site, dated February 2008, reference KL/76/080213/P2. ECUS Ltd were instructed by Amber Valley Borough Council to undertake additional groundwater and surface water sampling and analysis at the site to supplement the existing data.

Site Work

An ECUS Environmental Scientist visited the site on 12th June 2008 to undertake the sampling. Groundwater samples were taken from monitoring wells installed on the site during the previous site investigation, namely WS1, WS2 and WS7. In addition, two water samples were taken from shallow depth from the River Derwent, which adjoins the site. One sample was taken as far upstream of the main body of the landfill as possible while remaining within the site boundary and another was taken at a location considered to be downstream of the majority of the landfill material. The sampling locations are shown on the attached Figures 6 and 7.

Analysis

The water samples were submitted to ECoS Environmental Ltd, a UKAS and MCERTS accredited testing laboratory. Each sample was analysed for the following potential contaminants and chemical parameters:

Metals: arsenic, cadmium, chromium (total), chromium (hexavalent), copper, lead, mercury, nickel, selenium, zinc, magnesium, calcium.

pH

Polyaromatic hydrocarbons (PAH), speciated to the EPA 17 compounds

Total petroleum hydrocarbons (TPH), speciated to equivalent carbon number groups

Electrical conductivity

Ammoniacal nitrogen

Hardness (CaCO3 concentration)

Total organic carbon (TOC)

Speciated volatile organic compounds (VOC), including chlorinated solvents, benzene, toluene, ethylbenzene and xylene (BTEX).

A copy of the laboratory test report is attached to this letter.

Summary of Results

To provide an initial assessment of the potential significance of the concentrations of contaminants identified to Controlled Waters, contaminant concentrations have been compared against UK Drinking Water Standards (DWS) and Freshwater Environmental Quality Standards (EQS).

Neither of these standard systems are considered to be definitive ‘trigger concentrations’ for water contaminant concentrations, but they have been used as an initial screening tool to indicate possible areas of concern for further investigation.

Groundwater

In general, concentrations of most of the contaminants analysed for in groundwater were marginally greater than those recorded during the previous investigation.

None of the contaminants analysed for were recorded in concentrations greater than the applicable EQS values. The relatively high concentration of zinc previously recorded in borehole WS2 (101.7mg/l) in the previous investigation was recorded at a substantially lower concentration (4mg/l).

Similarly, the relatively high concentration of TPH previously recorded in borehole WS1 (2,950mg/l) is now less than 0.4mg/l.

The concentration of the PAH compound benzo(a)pyrene was recorded at concentrations in excess of the DWS value of 0.01µg/l in groundwater in each of the three boreholes. In addition, the concentration of total PAH was greater than the DWS value of 0.1µg/l in each of the three boreholes.

Chlorinated hydrocarbon compounds were recorded in concentrations greater than the detection limit in borehole WS1 only. However, none of the compounds recorded have EQS values published, except xylene, which was below the EQS value.

Surface Water – River Derwent

None of the contaminants analysed for were recorded in concentrations greater than the applicable EQS and DWS values in the upstream sample.

In the downstream sample, the concentration of benzo(a)pyrene and of total PAH were both marginally greater than the relevant DWS values.

The concentrations of 7 of the 17 PAH compounds are marginally greater in the downstream sample than the upstream sample. There is no discernable overall increase in the concentration of other contaminants in the downstream sample compared to upstream sample.

It should be noted that the concentrations of all PAH compounds except benzo(a)pyrene within the downstream sample are less than those recorded in the previous site investigation.

3

Conclusions

The analysis presented within this letter report appears to confirm the findings of the previous report, namely that there is evidence for an increase in PAH concentrations at the downstream sampling point compared to the upstream location.

Concentrations of contaminants within groundwater recorded at the site during this sampling exercise are generally less than the applicable EQS and DWS values, except for total PAH and benzo(a)pyrene, which suggests that the river is being affected by groundwater migration from the landfill.

However, no contaminants have been recorded within the River Derwent at concentrations greater than the EQS values, which are generally considered to be more relevant to the freshwater environment than the more stringent Drinking Water Standards.

Based on the information currently available, it is considered that the overall risk to the surface water environment is relatively low.

We trust that the above meets with your satisfaction. However, should you have any further queries, please do not hesitate to contact the undersigned.

Yours sincerely,

A M Grant BSc (Hons) MSc CGeol Senior Geo-environmental Engineer [email protected]

Hi Darren I have reviewed the recent data sent to me via email and can confirm that I agree with the conclusions, using the current data the site is having an impact on the river but the impact is minimal.

As such unless this impact becomes significantly more polluting it is extremely unlikely that the Environment Agency would be requesting further clean up at this point in time.

Thanks

Dear Darren,

Risk Assessment for Proposed Use of Lawn Cottage, Wyver Lane, Belper

We are pleased to report on our human health recent risk assessment for the proposed use of Lawn Cottage by Wild Peak Housing Co-operative.

Introduction

The property known as Lawn Cottage, on Wyver Lane, Belper, is owned by Amber Valley Borough Council (AVBC). It is the intention to sell the property to Wild Peak Housing Co-operative (WPHC) for residential use.

The property is adjacent to a former municipal waste landfill site. ECUS undertook a site investigation on the landfill and on Lawn Cottage in 2007, and there have been various phases of additional site investigation and soil sampling across the site between that time and December 2009.

These various phases of site investigation and risk assessment have indicated that existing soil contamination within the garden areas of Lawn Cottage make it unsuitable for residential use, due to elevated concentrations of polycyclic aromatic hydrocarbon (PAH) compounds.

In order to make Lawn Cottage suitable for general residential use, remediation works are required. The economic and legal aspects of various possible schemes to remove soils from the cottages of Lawn Cottage and replacing them with soils from elsewhere have been examined in detail by AVBC and have been found to be unfeasible.

A drawing showing a proposed layout of the property and immediate surroundings has been forwarded to ECUS by AVBC, showing some proposed remedial measures that may reduce the risk of soil contamination to the future residents. This document is an assessment of human health risks to future site users, based on this proposed site layout.

Proposed Site Use

The site use proposed is shown in the enclosed drawing (Appendix A). The pertinent aspects of the proposed site use are summarised below:

1) Main Lawn Cottage building to be used as a residence; 2) New ancillary building to be constructed to the east of Lawn Cottage (proposed use not

known); 3) New garden area to be created from existing farmer’s field (part of the former landfill) to the

south and east of Lawn Cottage; 4) There are to be raised beds for vegetable cultivation in all garden areas; 5) Garden area immediately to west of Lawn Cottage to be surfaced with BODPAVE 85 paving

grids. A square pond (designated as Pond 2 on the drawing) to be dug in this area; 6) Central garden area to be planted with trees to created a new woodland area. Irregular-

shaped pond (Designated as Pond 1 on the drawing) to be dug in this area; footpath constructed from BODPAVE 85 to run across this area, linking 5) to 7);

7) Parking area at far western end of garden area, surfaced with BODPAVE 85 paving grids.

Suggested construction details for the BODPAVE system, supplied by the manufacturers, are enclosed with this document (Appendix B).

Intended Purpose of the BODPAVE System

The BODPAVE system is intended by its manufacturers to provide a reinforced paving system for parking areas, footpaths, driveways, etc.

It is proposed to effect remediation of the site by using the BODPAVE system to provide a hard surface in the existing garden areas. This is intended to prevent exposure of the receptors (i.e., future residents of the site) to the contaminated soils below.

Contaminated Land Exposure Model

The pathways by which site residents can theoretically become exposed to contaminated soils in a standard residential site-use scenario as defined within the Environment Agency’s Contaminated Land Exposure Assessment (CLEA) model are as follows1:

1) Direct ingestion and inhalation of soil and dust; 2) Consumption of home-grown fruits and vegetables; 3) Ingestion of soil attached to home-grown fruits and vegetables; 4) Outdoor dermal contact with contaminated soils and indoor dermal contact with soil dust

trailed indoors; 5) Outdoor inhalation of dust generated from contaminated soils and indoor inhalation of dust

generated from contaminated soils, trailed indoors; 6) Outdoor and indoor inhalation of vapours generated from contaminated soils.

Without remediation, it should be assumed that all of the above pathways would be potentially active on the Lawn Cottage site following remediation. The critical receptor in the CLEA model for residential land use is a female child, with the critical exposure period being between the ages of 0 and 6 years old. There are several assumptions in the standard model on the exposure duration to the contaminated soils, e.g., number of days in a year spent in the garden; number of hours in those days spent in the garden, etc. The CLEA model allows justified adjustments to these assumptions to produce site-specific human health risk assessments.

1 Jeffries, J., and Martin, I., 2009. Science Report SC050021/SR3: Updated technical background to the

CLEA model. Environment Agency, Bristol.

The proposed layout features a variety of land uses; each of these will have a different combination of active exposure pathways. For the purposes of this assessment, the following uses of the site will be modelled:

Garden areas paved with BODPAVE; cultivation of fruits and vegetables in raised planters;

Wooded area, no BODPAVE system in place;

New garden area to south and east of Lawn Cottage, with cultivation of fruits and vegetables in raised planters.

Active Exposure Pathways in Garden Areas Paved with BODPAVE

The BODPAVE system consists of rigid plastic grids, laid on a construction of geofabrics and Type 3 sub-base. The plastic grids consist of round cells, 46mm in diameter with a solid base except for a small weep hole, and cross-shaped cells, 67mm in diameter. The effects of placement of the BODPAVE system on exposure pathways are summarised below:

1) Direct ingestion and inhalation of soil and dust

The placement of the Type 3 sub-base, geofabrics and BODPAVE grids makes direct contact and ingestion with the contaminated soils very unlikely; the entire construction would have to be removed to gain access to the contaminated soil to deliberately ingest it.

No fugitive dust would be generated from the contaminated soils, as they would be contained below the geofabric and sub-base layers.

Therefore, this pathway would be deemed to be inactive.

2) and 3) Consumption of home-grown fruits and vegetables and attached soils

The BODPAVE system would result in a very thin layer of imported clean soil at the surface in which cultivation of fruits and vegetables would not be possible. Fruits and vegetables would instead be grown in raised planting beds that are physically isolated from the contaminated soils below. These planting beds must be filled with clean imported soils.

Under these circumstances, these pathways would be deemed to be inactive.

4) Outdoor dermal contact with contaminated soils and indoor dermal contact with soil dust trailed indoors

As per the Direct Ingestion and Inhalation of Soil / Dust pathway, placement of the geofabrics, Type 3 sub-base and paving grids will make unintentional dermal contact with the underlying contaminated soils impossible. Similarly, the pavement construction will prevent the generation and release of dusts from the contaminated soil.

Accordingly, these pathways would be deemed inactive.

5) Outdoor inhalation of dust generated from contaminated soils and indoor inhalation of dust generated from contaminated soils, trailed indoors

With the paving system in place, generation of dust from contaminated soils could not occur, and therefore these exposure pathways would be deemed to be inactive.

6) Outdoor and indoor inhalation of vapours generated from contaminated soils

The placement of the BODPAVE system would not prevent generation of vapours from contaminated soils. Although it is likely that the placement of the system would retard emission of vapours from contaminated soils into the air, the system is designed to be permeable, and therefore would let vapours through. It is probably not possible to estimate the degree of vapour transmission that the paving system would prevent or allow, and therefore, these pathways are assumed to be active.

Active Exposure Pathways in the Proposed Woodland Area

It is understood that this area is to be used for managed woodland and coppicing. It will be fenced off from the other areas of the site. There will be a footpath, constructed with BODPAVE, crossing the area to allow access. There is no standard land-use model within the CLEA system that is similar to this land use, and therefore a site-specific risk assessment must be undertaken, based on the following assumptions on the possible exposure pathways.

1) Direct ingestion and inhalation of soil and dust

The contaminated soils will remain at the surface, and these pathways will be active to some degree. The area would not be used as a general garden area for recreational purposes, and therefore the standard assumptions on exposure on the CLEA model should be modified to more closely resemble a feasible worst case for exposure in this area.

2) and 3) Consumption of home-grown fruits and vegetables and attached soils

Assuming that fruit trees are not grown in this area, these pathways will not be active.

4) Outdoor dermal contact with contaminated soils and indoor dermal contact with soil dust trailed indoors

See 1) above. It is understood that this area would normally only be entered either to cross the footpath to the other part of the site, in which case contact with contaminated soils would not be expected to occur, or to maintain the woodland. Again, the exposure durations within the CLEA model should be adjusted based on the predicted actual site usage.

5) Outdoor inhalation of dust generated from contaminated soils and indoor inhalation of dust generated from contaminated soils, trailed indoors

See 1) and 4) above.

6) Outdoor and indoor inhalation of vapours generated from contaminated soils

Any vapours generated by contaminated soils would be assumed to be transmitted to the air as per the standard CLEA model. However, the exposure durations should be modified in line with the predicted site use.

Assumptions Made in CLEA Model for Exposure in the Wooded Area

As stated above, generalised assumptions have to be made to estimate the exposure to residents to contaminated soils in the proposed wooded area of the site. The assumptions made are as follows:

Only adults between the ages of 16 and 65 have access to the area;

The residents spend every day of the year at the property (i.e., no holidays, etc.);

The residents spend 261 days a year in the wooded area (i.e., 5 days a week);

The residents spend 3 hours a day in the wooded area and 10 hours a day in Lawn Cottage.

Active Exposure Pathways in the New Garden Area

The new garden area that is proposed to the south and east of Lawn Cottage appear should be assumed to be used as modelled with the standard residential land use model, except that the exposure pathways for ingestion of home-grown fruits and vegetables and attached soils should be de-activated, as these are to be cultivated within raised beds filled with clean imported soils.

Summary of Active Pathways for the Proposed Land Uses

The table below is a summary of the exposure pathways that will be potentially active in the three areas of proposed land use.

(SSAC) for each of the three different proposed land uses, using the combinations of active and inactive exposure pathways listed in the table above. The CLEA model input parameters for the proposed garden areas surfaced with BODPAVE, wooded area and new garden area to the south and east of Lawn Cottage, are enclosed with this report (Appendix C, D and E, respectively).

Comparison with Contamination Concentrations

The statistical analysis tool ESI Contaminated Land Statistical Calculator has been used to calculate the upper confidence limit (UCL) at a 95% confidence level (equivalent to the US95 value in the withdrawn CLR7 report) in accordance with recent authoritative guidance12 for the concentrations of the contaminants of potential concern on the site. Where the UCL is less than the SSAC for a given contaminant, it can be concluded that the contaminant does not pose an unacceptable risk to future site residents given the proposed site use.

The UCL values for soil samples taken from the garden area to Lawn Cottage has been used as the comparison to the SSAC calculated for the proposed garden areas surfaced with the BODPAVE system and the wooded area. The UCL values for soil samples taken from the field area to the south of Lawn Cottage have been used for comparison of the SSAC calculated for the new garden area to the south and east of Lawn Cottage.

The table below summarises the comparisons between the UCL values and the calculated SSAC for the potential contaminants of concern. Where the UCL exceeds the SSAC, it is highlighted in bold in the table. Where ‘NR’ is shown in the table, this is because there is no exposure pathway to the receptor, and an SSAC cannot be calculated for the linkage, i.e., in practise, there is no risk from the pathway.

Contaminated Soil Human Health Risk Assessment Summary

The table above shows that for all potential contaminants of concern, except the PAH contaminant benzo(a)pyrene, the relevant UCL values are less than the calculated SSAC.

The UCL values for the soils within the wooded area (13.6mg/kg) are marginally in excess of the SSAC (11.2mg/kg), which has been calculated using conservative assumptions in the CLEA model. It is therefore considered that the concentration of benzo(a)pyrene does not pose an unacceptable risk to human health within the wooded area.

The UCL value for the soils within the field to the south of Lawn Cottage is a little over twice the SSAC calculated for that land use, calculated using essentially the standard CLEA model assumptions, which are generally considered conservative. This margin of exceedance is not considered to represent a ‘significant potential of significant harm’ to human health as described within Part IIA of the Environmental Protection Act 1990 and associated Defra guidance13.

13

Defra, 2008. Guidance on the Legal Definition of Contaminated Land.

Durability of the BODPAVE System

The potential contaminant of concern within the garden of Lawn Cottage have a long residence time in soils and will not significantly reduce in contamination over time.

It is therefore essential that the paving system is durable and will prevent exposure to contaminated soils throughout its intended lifetime. We note from the proposed drawings that a CBR value of 2% has been assumed for topsoil within the garden. This is likely to be an over-estimate.

Ground Gas Risk Assessment

The previous ground gas risk assessment undertaken for Lawn Cottage14 found that the following precautions against ground gas ingress into new buildings would be necessary:

a) Reinforced concrete cast in situ floor slab with at least 1200g hydrocarbon resistant damp-proof membrane (DPM).

or

b) Beam and block or pre cast concrete slab and minimum 2000g DPM or reinforced gas membrane.

All services which penetrate through the DPC / membrane should be sealed so that the penetration point is gas-tight.

If option b) above is to be adopted and a reinforced gas membrane is to be used instead of a 2000g DPM, the gas membrane should be resistant to radon, carbon dioxide, methane and hydrocarbon vapours.

Answers to Specific Questions from the Client

We have been asked by AVBC to comment on the following specific questions:

1) Would the pond need lining as part of the capping system?

The pond should be lined as part of the capping system, as when the water level drops, contaminated soils will be exposed, and exposure could result. In addition, the site investigation identified sandy soils below the garden to Lawn Cottage, which would allow free drainage of an unlined pond.

2) Would the pond become contaminated if not lined?

There is a significant probability that the ponds would become contaminated if not lined.

In addition, it is noted that digging the ponds would create contaminated waste soils. It is understood that the cost of disposal of contaminated soils has been one of the major constraints in bringing the site back into use.

3) Would ECUS require tree planting pre-validation? - i.e. is it going to be a vital element in the remedial measures

The presence or absence of trees in the wooded area does not add to or subtract from the risk to human health from contaminated soils in this area. It is the placement of fencing and a hard-paved footpath, together with a restriction on access to children that will be the methods by which the risks caused by exposure to contaminated soils are to be managed.

BodPave85TYPICAL PROFILE

The unique design of BodPave®85 resists lateral movement,improves traction and allows expansion & contraction whilst promoting optimum grass growth, root protection and surfacestabilisation. The open cell structure provides high surface waterinfiltration and is suitable for source control within a SUDS profile.

BodPave®85 should be installed onto a well prepared, freedraining, firm and relatively level sub-base (typically a DoTType 1 or reduced fines Type 3) using either Boddingtons‘Reduced-Dig System’ or by employing a full sub-base constructionincorporating a Tensar TriAx™ TX160 geogrid reinforcement layer. Paving grids simply connect together and are then filled with either asand:soil rootzone and seeded or turfed for a grass surface, or filled with an angular aggregate for a gravel surface asdetermined by the application. Construction profiles for each application will be determined by the specific siteconditions & loading criteria. Detailed design literature and technical support are available to download online as shown below.Please note : All BodPave®85 applications must be provided with sufficient and adequate drainage facilities in order to function asintended. Failure to ensure this may compromise overall performance.

Open cell structure promotesoptimum grass growth

Castellations aid lateral grassgrowth and increase traction

1. Install edge retention as specified: Either tanalised timber boards, concrete, steel or plastic kerbs as appropriate.2. Ensure that the sand:soil rootzone bedding layer is the correct & uniform thickness, is level & well consolidated.3. Place the paver units: With the 2 sets of edge loop connectors facing in directions of laying, place BodPave®85 firmly onto the surface

so that its ground spikes are pressed fully into the bedding and the base of the paver cells sit flat on the bedding layer surface. Connectadjacent pavers together by slotting the edge cell connectors down into the edge loops (LOOPS ALWAYS LEAD) & progress over the area in rows. Pavers are locked in place by snap-fit clips. If paver separation is required, clips can be dislocated using careful, firm hand or screwdriverpressure or by gently twisting the paver joints. Use protective gloves to avoid abrasions.

4. Pavers can be offset by 1 cell increments or cut to fit around obstructions & curves using a hand or power saw. The use of cut-pieceswhich do not have integral snap-fit connectors should be avoided wherever possible.

5. Fill pavers with specified propriety rootzone to finished levels: 5-7mm below top of the cells after settlement. A light whacker plate may be used to consolidate the pavers and settle rootzone fill. Do not overfill or over consolidate.

6. Carry out a normal seeding, fertilising & watering programme. A light top dressing may be applied to just cover the seed and to provideadequate germination conditions. Do not overfill the paver cells. Thin-cut or Washed Turf may be lightly rolled into the surface as analternative if required.

7. The surface may be trafficked immediately for critical access purposes, but it is preferable to allow grass to fully establish prior to use.

Note 1: If Tensar TriAx™ TX160 geogrid is omitted, the total Granular Sub-Base (GSB) layer thickness (Tx) must be increased by minimum 50%.Note 2: A‘DoT Type 1’ sub-base may be used provided that an adequate drainage system is installed. Alternatively, a permeable/open-graded

(reduced fines) sub-base layer (i.e Type 3) may be specified, e.g. as part of a Sustainable Urban Drainage System (SUDS). Note 3: If construction traffic axle loads will be greater than 60kN (approx’ 6 Tonnes), minimum sub-base thickness over Tensar TriAx™ TX160

geogrid shall be 150mm. Maximum sub-base particle size should match minimum sub-base thickness but not exceed 75mm diameter. For sub-base thicknesses of around 100mm, a minimum 37.5mm particle size should be adopted to allow effective installation of TensarTriAx™ TX160 geogrid.

Note 4: Where drains are omitted and a 'reduced fines' sub-base is specified for SUDS this must be covered with either a geotextile fabric(i.e. Boddingtons BGT100) and/or a clean, suitably graded gravel blinding to avoid the bedding layer leaching into the sub-base.

Note 5: Specific advice on CBR% strengths, ground conditions and construction over weak ground with a CBR less than 1% is available fromBoddingtons Limited. CBR% = California Bearing Ratio, a measurement of subgrade soil strength.

Note 6: Typical standard drainage detail: 100mm diameter perforated pipe drains laid at minimum gradient 1:100, bedded on gravel in trenchbackfilled with ‘DoT Type A’ drainage aggregate, trench covered &/or wrapped with a geotextile fabric (i.e Boddingtons BGT100), pipes leading to a suitable outfall or soakaway. Drains installed down centre or one edge of areas up to 5m wide. Wider areas may require additional lateral drains at 5m - 10m centres. Drainage design to be determined by the specifier based on specific site conditions.

Note 7: Drainage for a Sustainable Urban Drainage System (SUDS) application will vary according to the site but generally omits the requirement for extensive pipe & trench drainage systems within the sub-base layer and may require an additional layer of BGT100 geotextile fabricat base of construction.

Note 8: Rootzone bedding and paver fill must be a free-draining, structurally sound propriety blend of sand:soil or sand:compost such as used in sports/golf construction & normally identified as a 60:40 or 70:30 ratio blend. The use of site-won materials or in-situ self-blending is NOT recommended without taking further advice.

Note 9: Maximum advised gradient for traffic applications: 12% (1:8) 7º. Bodpave®85 has specific pegging points if required for steep slope applications. Pegging is not necessary for standard access route applications.

Note 10: BodPave®85 complies with BS8300:2009 - “Design of buildings and their approaches to meet the needs of disabled people” - Code of Practice. (ISBN 978 0 580 57419) & Building Regulations Document ‘M’ section 6.Specific advice on the use of BodPave®85 on steep slopes, drainage suitability and Sustainable Urban Drainage Systems (SUDS)applications, can be obtained from Boddingtons Limited.

BODPAVE®85 PAVING GRIDS - ‘REDUCED DIG’ METHOD®

After confirming that the ground conditions are suitably firm and free-draining for this type of ‘reduced dig’application, one of the following methods of installation should be followed.A. FOR GRASSED SURFACES1. Cut the grass very close to the surface or where specified remove the turf/topsoil to a depth of <100mm

according to local levels. Dispose of all debris. Level the formation layer, lightly consolidate & install drainsas specified.

2. Install edge retention as specified: Either tanalised timber boards, concrete, steel or plastic kerbs as appropriate.3. Place a layer of Tensar TriAx™ TX160 geogrid on the formation layer and ensure it is flat to the surface by

pinning as required. Note: An optional geotextile fabric layer (Boddingtons BGT100) can be placed onto the formation prior to the Tensar TriAx™ TX160 geogrid installation, to prevent migration/contamination (see Note 2).

4. Place a 35 - 50mm thick bedding layer of 10 -20mm diameter angular gravel / aggregate evenly over the geogrid. The geogrid must not be allowed to become exposed above the gravel / aggregate layer.

5. With the 2 sets of edge loop connectors facing in directions of laying, place the BodPave®85 firmly onto the screeded bedding layer so that the ground spikes are pressed fully into the bedding and the base of the paver cells sit flat on the surface. Connect adjacent pavers together by slotting the edge cell connectorsdown into the edge loops (LOOPS ALWAYS LEAD). Pavers are locked in place by the integral snap-fit clips. Progress over the area in rows. Use protective gloves to avoid abrasions.

6. Pavers can be offset by 1 cell increments or cut to fit around obstructions & curves using a hand or power saw. The use of cut-pieces which do not have integral snap-fit connectors should be avoided wherever possible.

7. Fill pavers with the specified propriety rootzone to finished levels of 5-7mm below the top of the cells after settlement. A light whacker plate may be used to consolidate the pavers and settle rootzone fill. Do not overfill the cells. Additional settlement of the rootzone may occur where an open graded bedding is used,& further topping-up may be required.

8. Rootzone fill must be a free-draining, structurally sound propriety blend of sand:soil or sand:compost such as used in sports/golf construction & normally identified as a 60:40 or 70:30 ratio blend. The use of site-wonmaterials or in-situ self-blending is NOT recommended without taking further advice.

9. Carry out a normal seeding, fertilising & watering programme. A very light top dressing may be applied to just cover the seed and to provide adequate germination conditions. Do not overfill the paver cells. Thin-cut or Washed Turf may be rolled into the surface as an alternative if required.

10. The surface may be trafficked immediately, but it is preferable to allow grass to fully establish prior to use.

B. FOR RETAINED GRAVEL SURFACESAfter confirming that the ground conditions are suitably firm and free-draining for this type of ‘reduced dig’application, the following method of installation should be followed.1. Follow steps 1-6 above. Note: An optional geotextile fabric layer (Boddingtons BGT100) can be placed onto the

formation prior to the Tensar TriAx™ TX160 geogrid installation (Step 3), to prevent migration/contamination (see Note 2).2. Fill the pavers with the specified angular gravel or aggregate. Preferably a clean, evenly graded angular

material with a range of 5 - 20mm diameter. Rounded 'pea gravel' is not recommended.3. Consolidate the surface using a light vibratory whacker plate if required.4. Refill any localised low areas with aggregate and repeat consolidation until satisfied with final compacted finish.5. The surface can be trafficked immediately.

Protecting Wildlife for the Future

Introduction Amber Valley Borough Council requested Derbyshire Wildlife Trust to undertake an ecological survey of the garden of Lawn Cottage, Wyver Lane to identify any potential impacts on habitats or species of conservation importance.

Methods The site was visited on 9th August 2010 by Kieron Huston (Senior Local Wildlife Sites Officer) and Trevor Taylor (Local Wildlife Sites Officer for Planning). A walkover survey was undertaken to assess the value of the garden habitats and check for any signs of use by badgers. A pond survey was undertaken to check for signs of breeding amphibians. Broad habitats were identified and a species list was compiled. Casual observations of other fauna were also noted.

Results

Garden vegetationThe site is formed by the boundaries of the garden of the property Lawn Cottage. The garden includes both native and non-native plant species with many ornamental and exotic species present. In the last few years the garden has been neglected and many of the trees and shrubs have grown outwards to form denser thickets of vegetation. The garden includes a variety of different habitat types including areas of acid grassland, rough neutral grassland, tall ruderal herb vegetation with nettles, thistles, rosebay willowherb, ragwort and teasel. A large number of fruit trees (apples, damsons etc) have been planted.

Mature conifer trees are present along the northern and eastern boundaries. Elsewhere various willows, cherries, lilac and pine all occur.

Pond and amphibiansA small garden pond is present surrounded on most sides by a low growing juniper. The pond is composed of a small pre-formed liner set on bricks on the ground. A series of pond samples did not record any amphibian adults or larvae.

BadgersAn area of disturbed bare soil could have been the result of badger activity, but on it’s own is inconclusive and no other signs were observed.

Other fauna A range of common wildlife including 8 species of butterfly, honeybees, several species of bumblebee, wasps, grasshoppers, hoverflies, ichneumon wasps, ants and moths were observed during the visit.

Nature conservation assessment

Vegetation The garden does not support any protected species or any habitats of high nature conservation value. However, consideration does need to be given to the possible presence of what might constitute a traditional orchard. The definition of this UK BAP Priority habitat is based on low intensity of management which has probably been the case in this instance. However, the fruit trees do occur together with other species of tree and shrub and the primary use of the site was as a garden as far as we know. The number of fruit trees points to domestic use and we are inclined in this instance to consider the site better classed as a garden.

BadgersThere remains a possibility that badgers may be used the site for foraging and badger setts do exist in the area.

Amphibians No amphibians were found on the site during the survey. Furthermore the margins of the liner sit above the ground level and have a lip making it difficult for newts, toads and frogs to access the pond, other than by crossing the juniper plant that surrounds the pond on most sides. It is thought that this forms an effective barrier to most amphibians.

In addition we have no records of great crested newt being present in this area.

ReptilesNo reptiles were observed at the site during the visit. However, grass snake is known to occur nearby.

Other wildlife valueThe garden provides a range of valuable habitats for wildlife. The presence of many flowering herbs and shrubs including numerous buddleia bushes has proved attractive to butterflies, bumblebees, hoverflies, ichneumon wasps and honeybees.

There is an active beehive (honeybees - Apis mellifera) on site located at the western end of the garden near the start of the drive.

The range of wildlife present is typical of many larger more diverse gardens and includes many common and widespread species.

Impact of the proposed development on wildlife The impact of the proposed development on nature conservation is low, but should still be considered as temporarily adverse at a local level (i.e. Parish) due to the loss of a wildlife rich garden.

However, there are no recognised habitats of county, regional or national nature conservation value present on the site.

The impact of the proposal on protected species is thought likely to be negligible.

The impact of the proposal on fauna associated with the garden is likely to be adverse due to loss of vegetation and soil. However, there are no records of any species of high nature conservation value being present and the impact is thought unlikely to be significant at a wider scale. The small size of the site and the habitats present are unlikely to support significant populations of any one species or any rarer species.

Proposed mitigation The adverse impacts on wildlife in this area will in time be mitigated by the proposed restoration of the garden, although this is subject to how the garden is managed by the new owners of the property.

Soil will be re-used on a nearby piece of land and some invertebrates will persist within this soil as pupa or larvae.

Conclusions

We have not identified any features of nature conservation interest that pose a significant constraint to the proposal or any that necessitate further survey work.

The site is of value to wildlife due to the presence of a diversity of native and non-native plants (many of which have nectar rich flowers or fruits) and the complex nature of the garden. The presence of trees, shrubs, areas of tall ruderal, garden, bare ground and a pond as well as the sheds and other man-made structures all increase the range of opportunities for wildlife and increase the ability of the site to support wildlife. However, many of the species present are likely to be quite widespread in their distribution and many will be capable of colonising new sites relatively rapidly. The site is also small so significant populations of any one species are unlikely and the likely presence of rarities is thought to be low.

The value of gardens for wildlife is not formally recognised in the context of planning or the Local Wildlife Sites system, but clearly gardens do make an important contribution to maintaining biodiversity and in some situations, can individually or collectively, be vital in this role. The restoration of the garden should take into account the needs of creating a wildlife friendly garden and

provide a mixture of shrubs and trees as well as areas of grass and a pond with associated wet margins. The pond should be constructed so that it is accessible to amphibians.

Recommendations

� Undertake works in the autumn and winter

� Re-locate the beehive if possible

� Maintain a watching brief for badger, reptiles (especially grass snakes) and amphibians during the works. If any of these species are observed works should stop and further ecological advice sought.

� Ensure garden restoration includes wildlife friendly measures.
