1 INTRODUCTION

This Pollution Prevention Plan (the “PPP”) has been prepared in accordance with the requirements of Condition 5C of the Planning Consent for The Overtown Access Track dated 11th February 2013. Condition 5C states:

“The development shall only be carried out in accordance with methods,

requirements, timings (as the case may be) identified and described in a statement or

plan to be submitted and approved in writing by the Local Planning Authority before

the development starts, namely, as follows:

.. C. Pollution Prevention Plan

Reason: In the interests of the amenities of nearby residents and occupiers, and to safeguard the environment, ecology, species and habitats on and adjacent the site.”

This PPP will be subject to periodic review/updating, and as such is a controlled document. Changes to the document will be made by ScottishPower Renewables (“SPR”) and then issued to the holders of controlled copies named at the beginning of this document. Users should ensure they are referring to the most up-to-date version of the document and if in doubt should seek confirmation from SPR. The PPP will incorporate the measures that will be adopted by SPR in order to prevent environmental incidents occurring during the construction and operational phases of The Overtown Access Track. This PPP will detail the measures to be employed to minimise the risk of pollution, in particular for developing avoidance and mitigation measures to prevent the pollution of groundwater and two nearby ponds, and prevent the accidental discharge of fuels, oils, lubricants, paint or solvents.

2 POLLUTION PREVENTION PLAN During the construction phase ScottishPower Renewables Construction Project Manager in conjunction with the Infrastructure Contractor‟s1 site management shall oversee all the construction activities to ensure that mitigation measures described in this PPP are put in place and all activities are carried out in such a manner so as to minimise or prevent effects on the onsite ponds, groundwater2 and soils, and to prevent the accidental discharge of fuels, oils, lubricants, paint or solvents. There are no existing watercourse crossings on the Overtown Access Track site, however there is a small watercourse which exists approximately 50m southwest of the site perimeter, The PPP outlines the general pollution prevention measures to be implemented to limit the potential for contamination of both the ground and surface waters, at any stage of the development. These measures are designed and implemented in line with current technical

3 COMPLIANCE WITH POLLUTION PREVENTION PLAN It is the intention that all works carried out by SPR and their contractors on the site will be conducted in accordance with this PPP and any accompanying method statements. Where:

(a) there is any departure from a method statement;

(b) any tasks/works/operations are being done without a method statement;

(c) monitoring of the onsite ponds and groundwater indicates elevated levels of specified contaminants;

(d) pollution of groundwater and surface water;

(e) fuels, oils, lubricants, paint or solvents are discharged,

the Ecological Clerk of Works3 (“ECOW”) shall be entitled to prescribe such action(s) (including immediate cessation of the relevant tasks/works/operations) that will be implemented by SPR or any of their Contractors. SPR or their Contractors shall be given reasonable notice to react to the instruction of the ECOW and exceptions will be made in the case of an emergency. 4 OBJECTIVES OF THE POLLUTION PREVENTION PLAN The key objective of this PPP is to ensure that measures are in place to minimise pollution risks at The Overtown Access Track. This objective will apply to all phases of the Access Track development, covering; construction of the Access Track, the construction of the Windfarm, operation of the Windfarm and the future decommissioning of the Windfarm and Access Track. The decommissioning of The Overtown Access Track will occur after the decommissioning of Coal Clough Windfarm. This PPP details the procedures to be followed during the construction and operational phases of the Overtown Access Track in order to prevent any adverse environmental effects. In particular, the PPP will include procedures detailing:

3 The “Ecological Clerk of Works” refers to the consultant appointed by ScottishPower Renewables (UK)

Limited.




5

(a) Water Catchments and Quality;

(b) Use and storage of fuels and oils;

(c) Role of Ecological Clerk of Works;

(d) Method Statements;

(e) Training;

(f) Management of waste The PPP will include details of the specific activities that will be undertaken during the construction of the Overtown Access Track . These activities will include:

(g) Construction of the site compound;

(h) Construction of the junction from Red Lees Road onto The Overtown Access Track;

(i) Construction of The Overtown Access Track;

(j) Construction of the junction from The Overtown Access Track to The Long Causeway;

(k) Construction of the Overtown Access Track drainage system;

(l) Fuel and chemical storage; and

(m) Other general site activities.

The activities to be undertaken during the operation of the Overtown Access Track contain significantly less work input when compared to the construction phase, and therefore SPR propose to adopt the procedures developed for the construction related activities as appropriate. As part of the PPP, a Pollution Incident Procedure (PIP) will be included within this document. The PIP uses a flow diagram approach to enable any spillages to be dealt with in a quick and efficient manner. 5 ROLE OF THE ECOLOGICAL CLERK OF WORKS The Ecological Clerk of Works (“ECoW”) shall monitor the site procedures outlined within the PPP. The ECoW will be nominated by SPR and will have the specific remit of monitoring compliance with the PPP during the construction phase to the extent the ECoW considers is required. The ECoW shall report any breaches to the SPR Construction Project Management Team. The Activities tables (in Section 0) outline the specific procedures in relation to which SPR must procure compliance. The role of the ECoW shall involve training of nominated personnel to carry out these procedures in a manner likely to minimise the potential for pollution.

6 STORAGE OF MATERIALS: STORAGE OF OIL/FUEL AND OTHER CHEMICALS All storage containers shall be clearly labelled in accordance with COSHH requirement with contents and volume and stored in an upright position. The COSHH data sheet (manufacturer‟s safety data sheet) shall be stored by the Infrastructure Contractor in the Site‟s COSHH Register. Storage of oils and chemicals shall be controlled (such as segregation) to prevent a reaction between different types. All oils (and fuel) shall be stored in suitable tanks at ground level in a designated area within a bunded storage area within the site compound, and these tanks will have secondary containment in accordance with The Control of Pollution (Oil Storage) (England) Regulations 2001 as amended. SPR expects The Water Environment (Oil Storage) (Scotland) Regulations 2006 as amended to also be adhered to as best practice on site. The storage area shall be secure and will be located to avoid damage through vehicular collisions or vandalism. Storage of oil/fuel and other chemicals shall take place in pre-approved locations within the temporary site compound at The Overtown Access Track. All storage tanks will be:

(a) located further than 50 metres from a spring, 10 metres from a watercourse and 50 metres from a well or borehole;

(b) manufactured and tested to a recognised standard, under a quality assurance system complying with BS EN ISO 9001:2000;

(c) installed by a technician who is registered with a professional scheme, such as the one operated by OFTEC;

(d) of sufficient strength and structural integrity to ensure that it is unlikely to burst or leak;

(e) in guaranteed working order, with a design life of 20 years; (f) marked with the product type and tank capacity; (g) double skinned and located within a bunded area capable of containing 110%

of the largest capacity vessel stored therein; (h) installed with valves, which shall be shut and locked when not in use; and (i) fitted with a notice telling users to keep valves and trigger guns locked, and

within bunded areas, when they are not in use. An inspection regime shall be implemented to routinely inspect tanks, pipework and bunds on the Site and effect repairs immediately. In the event of an accidental spillage of oil or fuel the procedures within „Pollution Incident Procedure Flowchart‟ - Appendix 2 of this submission shall be adhered to. 7 METHOD STATEMENTS A series of method statements shall be prepared during the construction phase to supplement the information provided in this Plan and fulfil obligations under the Planning Conditions in relation to the Overtown Access Track and Construction Design and Management (“CDM”)4 regulations as necessary. Separate method statements will be prepared for every construction task and/or any other operations that have the potential to give rise to pollution of the two nearby ponds, groundwater or the accidental discharge of

4 The Construction (Design and Management) Regulations 2007 (CDM2007) came into force on 6

th April 2007.

The key aim of CDM is to integrate health and safety into the management of the project and to encourage

everyone involved to work together.

fuel, oil, lubricants, paint or solvents. Each method statement will:

(a) Outline how the specific task will be carried out, including details of pollution mitigation measures;

(b) Provide a description of its location; (c) Contain a detailed risk assessment of each task; (d) Contain a list of pollution prevention and control equipment to be provided (e) Indicate the location at which this equipment will be stored; (f) Identify communications procedures; and (g) Provide a timetable.

The Infrastructure Contractor must demonstrate to the ECoW that by working in accordance with the agreed method statements, any discharges and run-off will be suitably controlled and treated. 8 TRAINING SPR will provide pollution prevention training as part of the Site Induction to all site-personnel (including contractors and sub-contractors) before they are allowed on site to ensure they are aware of pollution prevention methods. The pollution prevention training details will be included within the site induction information. As a minimum the training will include:

(a) the requirements and use of the PPP;

(b) key risk activities and sensitive areas;

(c) the SPR communication system;

(d) incident reporting plan/form;

(e) site personnel responsible for dealing with site incidents;

(f) use of spill kits; and

(g) the contractor passport identification system. 9 WATERCOURSES AND WATER CATCHMENTS There are two ponds located on the Overtown Access Track site, and care shall be taken to avoid any significant impacts on them. The “Activities” table (Section 0) presents a tabulated summary of the specific site activities that may impact on the quality of the ponds during the construction and operational phases of the Overtown Access Track. In addition, the tabulated summary includes site procedures and mitigation measures that must be adhered to on an ongoing basis to ensure the impact on the watercourses is minimised. As part of the pollution control procedures, SPR have instigated a baseline survey of water quality for 6 months prior to construction. The scope, sampling locations and analysis sweet as carried out by AA Environmental is included in Appendix 5. SPR shall continue this water monitoring at the same locations over the construction period and 6 months post construction. 9.1 Ground and Surface Water

Likely significant effects occur mainly during the site preparation and construction phase and include alterations to the drainage network causing changes to surface




8

runoff volumes and associated flood risk and/or low flows; erosions of soils causing soil loss; chemical pollution of onsite ponds and groundwater. The Infrastructure Contractor shall implement the mitigation measures and best practice procedures identified in this document, including the SPR Environmental Awareness Water and Wastewater Management best practice document in Appendix 4 at the Overtown Access Track development where appropriate.

9.2 Water Management Measures Due to the size and nature of the development, drainage from the site will be via Sustainable Urban Drainage Systems (SUDS). The implementation of SUDS as opposed to conventional drainage systems provides several benefits by:

Reducing peak flows to watercourses and potentially reducing risk of flooding downstream;

Reducing the volumes and frequency of water flowing directly to watercourses;

Improving water quality by removing pollutants;

Replicating natural drainage patterns, including the recharge of groundwater so that base flows are maintained.

In the interest of expediting and ensuring the proficiency of the drainage design, SPR have contracted Donaldsons Associates Limited (“DAL”) to design construction stage drainage which the Infrastructure Contractor shall implement or provide a superior alternative to. The Construction Stage Drainage Design is included in Appendix 6:

6A Construction Stage Drainage Design;

6B – 6E Overtown Drainage Drawings;

6F Overtown Drainage Design Calculations. The implementation of water management methods shall be the responsibility of the Infrastructure Contractor, who will also take into account the recommendations made in this report.

9.3 General Management Measures In planning and carrying out any work in or near to watercourses, precautions must be taken to ensure that they are protected against pollution, silting and erosion. The Infrastructure Contractor shall install water control measures on a rolling basis prior to construction activities taking place. This shall help to ensure that all runoff is being adequately attenuated and treated during the construction process. There are a number of general mitigation measures that can be implemented with regard to the site construction and operation to safeguard the quality and hydrology of onsite ponds and groundwater. These measures include:

Appointment of an Ecological Clerk of Works by SPR to ensure that all works carried out are using best practice techniques;

The impacts of increased surface runoff and pollutants on the water environment to be included as part of the site set-up risk assessment to be produced by the Infrastructure Contractor;

Only clean rainwater should be allowed to directly enter surface watercourses and drains;




9

Cut-off Drains: Methods would include the construction of temporary and permanent drainage works to divert surface water away from construction activities and prevent surface water from entering excavations;

Reuse of water. Treated water from settlement ponds/ lagoons used to damp down access tracks in dry/ dusty conditions;

Recycling of water. Recycled water to be used in wheel washes (as required); and

Silt Fencing to be installed where appropriate on site by the Infrastructure Contractor to minimise wash-off from the access track at sensitive locations.

9.4 Access Track

This section of the PPP details the methods that can be used to control surface water runoff and protect the onsite ponds and groundwater, taking the design of the Access Track into account.

9.4.1 Access Track Design The following methods can be incorporated into the design of the access tracks to ensure that the onsite ponds and groundwater environment are protected during the construction and operation of The Overtown Access Track:

Access track to be designed to have adequate cross fall to avoid ponding of rainwater and runoff;

Access track to be designed with cut-off drains. Cut-off drains can be installed at regular intervals to prevent excess water running along the road and can direct water into road side drainage. An example of a cut-off drain is provided below;

Figure 1 Example of cut-off drain on access track to prevent erosion and direct

polluted surface water to treatment areas

9.4.2 Conventional Water Management

The following conventional water management techniques can be installed to help treat and attenuate the surface water runoff from the site access tracks during construction and operation:

Prior to construction of the access track, the Infrastructure Contractor shall identify flush areas, depressions or zones which may concentrate water flow.




10

These sections should be spanned with plastic pipes to ensure hydraulic conductivity under the road, and reduce water flow over the road surface during heavy precipitation;

The permanent drainage ditches serving the access track can be used to convey surface water runoff away from sensitive areas where pollution and suspended sediment issues are possible;

These permanent drainage ditches can also have outlets at frequent intervals to reduce the volume of water collected in a single channel and thus reduce the erosive potential. If the runoff from these outlets has had an appropriate level of treatment then it can be discharged back into the natural drainage network;

Straw bales and/or silt traps can be installed in drainage ditches to allow attenuation and treatment of sediment laden runoff. An example of straw bales being used to treat runoff is provided below;

Figure 2 Example of a straw bale being used to treat sediment laden runoff (note

the rod inserted into the bale to hold it in place)

Silt fences and straw bales can also be placed at areas at risk of erosion;

Excess silt to be disposed of in designated areas away from onsite ponds or drainage ditches;

Exposed ground and soil stockpiles should be minimised and silt fences and straw bales can be used to intercept sediment laden surface runoff; and

Flocculants can also be utilised in watercourses subject to significant sediment laden runoff. Flocculants are very effective at removing suspended sediment from water but they can also have effects on water chemistry. As such, it is recommended that the EA are consulted prior to the use of flocculants.

Removal of dirty water prior to backfilling of lagoons. Silt fencing to remain in place after backfilling for a period, and shall be removed prior to the Infrastructure Contractor leaving site.

9.5 Concrete Transportation

Concrete for The Windfarm shall be transported to The Windfarm via the Overtown Access Track. Care should be taken to ensure that the transportation of concrete




11

through the access track uses best practice measures. For instance:

All loads must be managed so as to avoid spillage while in transport;

All concrete transport vehicles to adhere to site speed limit to avoid spillage while in transport;

Load sizes must be assessed with regard for the type of vehicle being used, the slump of the concrete being transported and the ground conditions over which the load is travelling.

10 FLOOD RISK The EA Flood Map5 shows the site located in an area described as Flood Zone 1 in PPS 25. This zone is categorised as being the lowest flood risk and comprises land assessed as having a less than 1 in 1000 annual probability of river or sea flooding in any year (less than 0.1%). The EA Flood Map shows that marginal flooding in low lying areas approximately 1 km beyond the south of the Development may be possible during heavy and prolonged precipitation events. The NPPF states that for development comprising one hectare (ha) or above, the vulnerability to flooding, or the potential to add to flooding elsewhere should be incorporated in a Flood Risk Assessment. There are no active floodplains on the Development site, and the Environment Agency has no records of flooding at the Development site. The Development site lies within Flood Risk Zone 1 and has an overall hardstanding footprint of approximately 1.85 ha. The site drainage is designed to accommodate surface water runoff shed from any road, adjacent structure or hard standing as well as any runoff from adjacent lands, up to a 1 in 30 years (+20% Climate Change) return period design storm. Although the potential magnitude of increased flood risk from the Development could be minor, the likelihood of this occurring is considered to be unlikely as drainage ditches installed adjacent to the Development and attenuation tank will provide adequate storage for any additional runoff from new hardstanding. As such, the risk of flooding will not increase onsite or offsite as a result of the Development. Please also refer to the Appendices 6A – 6E for more detailed information and design calculations. 11 STORAGE OF FUELS, OILS, LUBRICANTS, PAINT OR SOLVENTS Diesel fuel will be the most frequently used on site and will be needed in large quantities when the construction phase of project is well established. The Infrastructure Contractor will store fuel in bunded static tanks located within the contractor‟s compound. There will be a tank for plant able to return to the contractor‟s compound and a tank for the generator. Otherwise, fuel will be stored in fully bunded “fuel flasks” located at strategic locations, generally where plant activities are concentrated. All fuel containers will be locked or stored in locked containers when not in use. The storage of fuel in 205 litre barrels will not be permitted on site, 25litre jerry cans may be used occasionally but only if stored in a lockable bunded area or on a drip tray for temporary usage.

12

The main fuel storage facility shall be built at the site contractor‟s compound away from existing or made drainage features. Bunded steel tanks shall be placed within a deepened concrete pit with storage for at least 120% of the tanks fuel storage capacity. Once the tanks are installed a cover will be placed over the tanks and pit to reduce the amount of rainwater collected. A concrete plinth will extend out in front of the tanks to form an apron large enough to accommodate all delivery vehicles to site and for mobile site bowsers to be filled.

11.1 Fuel Delivery Fuel will be delivered up to twice a week from a national supply company. Enough space will be allowed to park the delivery tanker as close as possible to the tanks to minimise the amount of hose required. A spill kit and absorbent granules will be kept at the tanks. The main operation of the delivery nozzle, turning on and off and attaching it to and disconnection from the tanks delivery pipe will all be carried out within the bunded section of the storage tanks. Where practicable the Infrastructure Contractor will plan to deliver fuel directly to each tank/fuel flask on site without any double handling of fuel. 11.2 Filling Double Skinned Mobile Bowsers This operation is similar to the delivery procedure. The tractor and bowser will be parked on the concrete apron in front of the storage tanks as close as possible to the tanks. The delivery nozzle will be operated inside the confines of the bowsers bunded area. The operator will switch to pump on and check the function of the nozzle when the nozzle is connected to the delivery pipe of the bowser. At no time will the operator leave the delivery operation in case the automatic nozzle does not function or some other failure occurs in the delivery system. When the bowser is full the pump will be switched off and the nozzle will be replaced in the storage tank. 11.3 Fuelling Plant The operators of manned plant must park their machines in an area easily accessible to the tractor and bowser away from existing or made drainage features preferably on level made up ground. Only the person nominated and dedicated to fuelling plant will be permitted to carry out the fuelling procedure. First the filler cap will be removed from the item of plant being filled. The bowsers delivery pump may then be started. The function of the delivery nozzle can be checked within the confines of the bunded area of the bowser by recirculating the fuel through the bowsers filler pipe. When the function of the equipment has been checked the item of plant can be filled. Only nozzles that cannot be locked open will be used to ensure that the refuelling operative must be present whilst fuelling. The person carrying out the fuelling of plant should check with the operator of each item of plant if fuel gauges are working correctly and to which level the tank is to be filled. It is important that the nozzle is fully drained before removal from the fuel tank and that any drips or splashes are immediately cleaned up using oil absorbent material. Static plant will be placed on drip trays but the same precautions when fuelling this type of plant as used when filling mobile plant will be taken. When using hand held containers to fuel plant (mainly petrol) a funnel or appropriate nozzle




13

attachment must be used. Precaution will be taken to avoid splashes caused by “glugging” or wind. All bowsers will carry spill kits and fire extinguishers. 11.4 Contingency Plans The Infrastructure Contractor will have an Environmental Management System certified to BS EN ISO 14001 1996. As part of this system, spill plans and emergency telephone numbers will be in place and displayed throughout the site. The Spill Plan will be briefed to appropriate personnel at the Site Induction and during Tool Box Talks. Spill kits will be available throughout the site for use by site personnel trained in their use by means of Tool Box Talk and practice drills. The “Activities” tables (Section 0) present a tabulated summary of the specific site activities that should be undertaken to ensure best practice is achieved when using fuels, oils, lubricants, paint and solvents during the, construction and operation of the Overtown Access Track.

12 MANAGEMENT OF WASTE All waste produced as a result of this project will be collected and disposed of to a suitably licensed site. All site working areas and compounds will remain tidy with covered skips provided for disposal of waste. Skips will be emptied regularly and will not be allowed to overflow. The “Activities” tables (Section 0) present a tabulated summary of the specific site activities that should be undertaken to ensure best practice is achieved when handling waste during the construction and operation of the Overtown Access Track. 12.1 Disposal of sewage/foul water All sewage and foul water arising from the use of mess and welfare facilities shall be collected in approved tanks within the contractors compound for removal from site by an approved contractor. The Infrastructure Contractor shall be responsible for the provision of sewage storage facilities on site and ensuring that the approved sewage collection contractor has all the necessary permits for disposal of the same sewage. There will be no permanent buildings on the Overtown Access Track site therefore there shall be no operational phase sewage/foul water.

14 POLLUTION INCIDENT PROCEDURE (PIP)

14.1 Emergency Response Arrangements

The Pollution Incident Procedure (“PIP”) includes emergency response arrangements to be followed in the event of an incident that potentially could impact on the two onsite ponds and the small watercourse 50m southwest of the site perimeter. Following an incident, arrangements will be made to contact the EPA emergency number and report the incident. The PIP will be used to address potential surface water risks for these areas.

14.2 Level of Response

During the construction phase the Infrastructure Contractor will ensure that any incident is immediately assessed in consultation with the ECoW (either directly or indirectly via radio or mobile phone). A judgement will be made on the level and seriousness of any incident, and the actions to be taken as a result. The Pollution Incident Procedure as set out in the flow chart in Appendix 2, has been designed to provide a quick guide to site personnel to determine the level of response and reporting mechanisms in the event of a spillage or overflow incident occurring. In addition, a table of actions has been provided to detail what actions will be taken in the event of a spillage or overflow event diagram.

14.3 Record of Incident

In the event of an incident, and following the completion of any cleanup operation, the Infrastructure Contractor will complete an Incident Report Form (as shown in APPENDIX 3 – POLLUTION INCIDENT REPORT FORM). The records of the incident and actions taken to mitigate the event will be on site.

19 APPENDIX 5 – COAL CLOUGH WINDFARM SURFACE WATER MONITORING – PRE CONSTRUCTION

AAenviro Ltd, 20 Ballantrae, East Kilbride, Glasgow, G74 4TZ, Scotland

Redacted Version of Quotation and Scope of Works Collection of samples A pro-forma checklist will be used at the time of sample collection to record the following information:

Date and time of sampling;

Name of sampler;

Description of sampling location including any reference characteristics;

Description of prevailing weather conditions;

Description of prevailing flow conditions;

Description of water colour and clarity;

Activities in catchment; and

Any unusual observations or smell and issues of material significance. A photograph of the sample site at the time of sampling will also be taken. Samples will be collected, stored and delivered to an approved laboratory in accordance with best practice. Analytical suite Our quote is based on the following suite of parameters for the baseline set of samples:

Following baseline monitoring, we would propose to review the analytical suite with a view, if appropriate, to reducing the number of parameters being analysed. At the time of sample collection, we propose to record water temperature, pH and conductivity in-situ, using calibrated field monitoring equipment to provide immediate water quality information. For a selection of samples, pH and conductivity would also be analysed in the laboratory for cross check quality control purposes. The sampling locations will be at the 2 number ponds on the access track.
