Dear Mr Smith,
Please find below an initial response from Environmental Health in connection with your request for environmental information. I was about to send it late on Friday afternoon when I found microfiche records of the original pre-1976 tipping file - containing copies of consents, correspondence (from April 1968) and inspection reports by the Public Health Inspector. When I responded on 5 June 2013 detailing what information we could provide I was unaware that we had this file for the Kempton Park landfill. I have started reviewing the microfiches, but it is quite painstaking a~ slow, so rather than hold up all the information, I am sending on what has already been prepared. The Public Health Inspector's file should not change the information provided in response to Question 2, but will add greater details about the nature of materials tipped, tipping progress and compliance with conditions.
Apologies for the delay in providing the information - hopefully the information will be useful. I will chase up planning today to see if they have located the original planning files from the new grandstand which contains the copies of the two site investigation reports.
Yours sincerely, Olivia " Olivia Flint Principal Pollution Control Officer Tel: 01784 446259

Dear Mr Smith,
Please find here the response of Environmental Health of Spelthorne Borough Council to your request for environmental information in connection with land at Kempton Park.
Question 1 Any records of contamination/ pollution inci~ents on the site There are two site investigations available dating from 2002 and 2003 as detailed in response to question 10.
84 We have record of one pollution incident relating to the site of Kempton Park Racecourse. There are though also a number of incidents relating to discharges to Portlane Brook, which abuts Kempton park Racecourse:

The pollution incident data represents incidents reported to the Environment Agency between January 1987 and the end of 2010. The Agency data is typically based on 8 figure grid references and consequently tend to only be accurate to about 100m. Please contact the Environment Agency for any further information about the incidents listed.
Question 2 Any records of landfill/Made ground Copies of extracts of the aerial photographs held by Environmental Health dating from 1946, 1972, 1992, 1998, 2002/3 and 2008 were previously provided by my colleague, Ms LizStrutt, on 24 June 2013. We identified microfiche records of 60 planning applications relating to Kempton Park racecourse. Of particular interest amongst these were the following applications:
Reference Year Description
SUN/FUL/5125/P 1965 Extraction of sand and gravel after treatment- REFUSED
SUN/DET/4125/P/A 1966 Extraction of sand and gravel
SUN/DET/4125P 1967 Extraction of sand and gravel
SUN.4125/P 1972 Extraction of Sand and Gravel from about 19 acres (7.6ha) as an extension to the existing workings and the variation in the order of working and restoration of the rest of the site to make land available for the construction of a golf course
85 SUN/FUL/4125/Z4 1968 Weigh bridge and weigh bridge office
C/FUL/77 /287 1978 Extraction of sand and gravel followed by refilling and restoration, on approximately 25 acres (10 hectares)
The microfiche records indicated that planning permission was granted on appeal by the Ministry of Housing and Local Government for extraction of sand and gravel from 95 acres (38.5 hectares) at Kempton park as four zones separated by the race track. A copy of the plan referred to in the Minister's decision of 22 September 1966 is provided. An exclusion zone was to be provided either side of the existing oil pipeline that dissected the north western filling area into Zones A and B and the south west area into Zone Cwest and Zone C east. Zone D in the south east corresponds with the site of interest. One of the conditions of the Minister's decision was that no working was to take placed in the hatched areas surrounding the filling zone (indicated on the accompanying pian). All fixed plant and machinery was to be located in the area show cross hatched black on the Minister's plan. The conditions largely focused on hours of work, access and lorry movements but did also include a submission and agreement by the local planning authority for a scheme of working (order, direction and method of working, stripping of topsoil and overburden, location and height of stockpiles and screening of working. A scheme of restoration, landscaping and after-treatment was also to be agreed with the local planning authority. This scheme was to include the extent and location of the excavated areas to be filled, the nature of the filling materials, the final levels of the restored land, the shaping of the lagoons and tree planting. The only stipulation on filling materials by the Minister was that they should not contain tarry, oil or noxious soluble substances. A condition required the excavation and restoration to be completed by 31 December 1977.
In January 1973 permission was granted by Surrey County Council (SCC)for the extraction of some 19 acres (7.6ha) in the south east corner of the park and for the variation of the order of working and restoration - there was a proposal for the southern extent within and to the east of the race track to be a golf course. A plan showing the approximate extent of the zones of filling is provided attached. It is not possible to reproduce the original AO sized... plan on the microfiche and so the approximate areas have been drawn onto current mapping on our GIS.The extension zone was Zone B-B on the eastern half of the site of interest. The planning permission was conditional to restricting filling materials below normal water level to stone brickwork, clean builders' rubble, clay or other overburden, being materials excavated from land in its natural state. Any empty tins, drums, tanks or other bulky articles included were to be completely filled or crushed before being deposited at the base. Materials to be used above normal water level up to within 3ft of the final surface of the land were as below normal water level with the addition of overburden, topsoil or any other soil substitute agreed with the Local Planning Authority. A further condition stipulated that the workings should not be filled with any domestic or trade refuse, nor with any materials other than those of an inorganic or non-polluting nature, and specifically none of the following: cyanides, chromates or phenols; any waste from metal finishing processes which may contain copper, lead, zinc, cadmium or manganese r~sidue; insecticides, weedkiller; acids in bulk; untreated sewage, sludge or cesspool contents or noxious liquids; radioactive waste, gas liquor, tarry wastes or petroleum products in liquid form. The Sunbury Urban District planning officer's report outlines that it was proposed to defer working in the north west quadrant (which had already commenced) in favour of working this extension first. The order of working in this area (Zone B-B) was to be from north to south as far as the hedging to be retained; and the remainder then worked from east to west, with the filling and replacement of stripped overburden and ultimate restoration taking place progressively behind. On completion of the application site (Zone B-B) working was to recommence on the north west quadrant (Zone A), proceeding in a clockwise direction with this area being partly filled and the remainder (19 acres/ 7.7 hal being left as a lake.
Working of gravels on the site ceased in February 1977, with tipping taking place in the extension area, with the remainder of zones having been reinstated apart from the silt pond area (Zone E). The application in 1977 by Greenham Sand and Ballast Co Ltd for extraction of sand and gravel, refilling and restoration on approximately 25 acres (10 hectares) was granted in 1978 with conditions that this be solely as an extension to the applicant's existing pit at Kempton park and that minerals extracted were only to be processed at the existing washing and screening plant. The new filling zones were Zone Fto the north of Zone B-B and beside Zone E and including the outbuildings associated with the house of Kempton Park [then called Hyde House - described as a listed mid 19th century construction], and Zone G correlating to the north and north west of the site of interest. The planning officer's report describes the site as one wooded area located to the south east of the existing plant site [Zone G] and a long
B6 strip of land north-east of Hyde House on the eastern boundary of Kempton Park [Zone F], the southern extent of which was presently covered by old disused glasshouses and sheds, while the remainder was overgrown with large, hummocks oftopsoil and overburden. Again the approximate location of these zones is indicated on the attached GISplan. The conditions also stipulated that a minimum of 0.76m capping layer of original topsoil and overburden was to be reinstated, with topsoil of at least 12 inches thick.
The planning officer's report describes the method of working as commencing in the area adjacent to the existing plant and proceeding in a clockwise direction with the southern part of the application site [Zone G], then moving to the western boundary of the northern area [ Zone FJadjacent to the existing silt pond and again proceeding in a clockwise direction. The existing silt pond was then to be infilled. The material was to be won by excavator and conveyed by a land conveyor to the existing plant and refilling and restoration would take place concurrently with extraction. The infilling material was to be Class I and" materials. It was estimated that the site [Zones F and GJ would contain approximately 560,000 tonnes of sand and gravel with a thickness of ballast of between 9 to 11 ft and overburden of 3 to 4.5 ft thick. The officer's report also described the application site as being "surrounded by land worked out in the recent past and still currently being reinstated", and that lithe past gravel operations have been undertaken in a reasonably satisfactory manner". The statement by Greenham submitted with the application proposed that the excavations be filled with Class I and II materials, with Class I(a) and (b) below the water line and Class" above the water line only. They further said that no domestic or trade wastes were to be accepted, and specifically no cyanides, chromates or phenols; any waste from metal finishing processes which may contain copper, lead, zinc, cadmium or manganese residue; insecticides, weedkiller; acids in bulk; untreated sewage, sludge or cesspool contents or noxious liquids; radioactive waste, gas liquor, tarry wastes or petroleum products in liquid form.
Appendix A of the planning application under reference 77/287 was trial bore information from boreholes drilled in 1969 and October 1976. A copy of this information is provided. The boreholes from 1969 provide depths to the clay strata, while the 1976 boreholes provide details of thickness/ depth of each strata encountered (both prior to mineral extraction and infilling).
The planning file contains a tipping consent granted by Spelthorne Borough Council to Greenham Sand and Ballast Co Ltd for the Kempton park Racecourse sitefor 26 February 1981 to 31 March 1982 under Section 94 of the Surrey County Council Act 1931- Note: these consents were usually issued annually. This consent permitted only the following waste types: a) Sludge and waste arising from dredging operations; b) Material excavated from land in its natural state, including excavated materials from building sites; c) Clinker and ashes; d) Materials from road works and bricks and hardcore; and e) Builders rubble.
But when tipping into a water area of less than one acre, only the following types of builders rubble were permitted to be tipped: Broken bricks, slate, hardcore, concrete, stone, rock, tiles and other ceramics and stoneware.
Obviously as this consent is only one of a number of annual consents that would have been issued, other waste types may have been allowed by preceeding or subsequent consents.
Q3. Any records of complaints about the site e.g. odour, noise, nuisance We are not able to provide detailed information about complaints or complainants, but can summarise the nature of complaints receive about Kempton Park Racecourse between 2004 and todate. Prior to 2004 a different database was used by Environmental Health and it is not possible to retrieve sufficient detail about the nature of complaints. Complaints relating to health and safety (nor accident reporting) and food hygiene associated with the regular market held at Kempton park Racecourse have not been included. In total we have 24 complaints: two relating to light pollution; two about toilets; and twenty about noise generally from concerts, fireworks, and the race tannoy.

Question 4 Historical development ofthe site As per our initial response, we direct you to the Heritage Conservation Team at Surrey County Council on archaeological issues.
I have reviewed each of the local history books held by Environmental Health (as follows) and have not found any reference to the historical development of Kempton Park:
• Richard H Lawrence (2001) The Years of Change: Growing up in Sunbury and Shepperton. The Sunbury and Shepperton Local History Society • JL & OM Barker (1999) Snapshots of Staines. Borough Books, Addlestone, Surrey • Althorp, J, Pollard, N, Pollard, S and Ward, P (2001) Sunbury and Shepperton Past and Present. Sunbury and Shepperton Local History Society. • Thompson, R (2004) Staines - A History & Celebration. Produced by the Francis Frith Collection for Ottakars. • Maryfield, P (2006) Staines - A History. Phillimore & Co Ltd, Chichester, West Sussex.
The official Kempton Park website gives an overview of the history of the racecourse (http://www.kempton.co.uk/History) as follows: "Thefirst ever race held at Kempton Park took place on the 18th July 1878. The Park had been bought by Henry Hyde six years earlier, who went on to fUlfil his ambition of building a racecourse on the site. A Royal Box was constructed injust 21 days in 1889 to cater for a visitfrom the Prince of Wales. The racecourse suffered major damage to the grandstand, restaurant, member's stand and tattersalls bar as a result of fire in 1932. Kempton Park was a major victim of both World Wars when all racing was abandoned and the site was used for a number of purposes related to the war. During the First World War, the park was used as a transit depotfor military vehicles. The Racecourses at Gatwick, Hurst Park and Sandown adopted Kempton Park'sfixtures until 1919, when racing resumed at Kempton. The site played a major role in accommodating prisoners of war throughout World War II.The main line rai! station situated on the grounds of the racecourse allowed German and Italian soldiers to be directly routed to the temporary camp that was set up. After the War had ended it became clear that the events of the previous six years had ruined much of the racecourse and a major reparation project ensued, before racing re-commenced in 1947.
88 The current grandstand was completed in 1997 after some redevelopment work. The racecourse was closed in May 2005 for the construction of the all-weather floodlit course which was completed eleven months later."
An older history of Kempton Park as an estate and Manor House is available at http:Uwww.british- history.ac.uk/report.aspx?compid=22249 - the discussion about the manor of Kempton Park starts from the sixth paragraph. This account also refers to the land being used by the army during the First World War. Another local website gives an account of the racecourse's history (http://thisisourvillage.co.uk/horse-racing/kempton-park-a- history) , recounting that during the First World war the racecourse was used as an army transit depot including tanks until 1919.
I attach map and aerial photograph extracts as follows: • Ordnance Survey County Series Middlesex XXV.6 1st (1866), 2nd (1895), 3rd (1915) and 4th(1934) edition maps • OSPost war maps from 1957 -1963, 1964 - 1973, and 1974 -1993 • Aerial photographs from 1946, 1972, 1992, 1998, 2002/3, and 2008 [not attached as sent by Liz Strutt on 24 June 2013]
The t" edition County Series maps shows a rifle range on the site of interest and a possible section of moat from a medieval manor at Kempton Park to the south of the then Kempton Park house and buildings. The second edition map shows a small gravel pit in the centre of the oval race course (off-site). This remains on the 3rd edition, when a large fish pond to the east of the site is shown as grassland. Reservoirs have been constructed to the north east and south east of site. The gravel pit remains on the 4thedition. The 1946 aerial shows historic scarring associated with the off-site gravel pit feature. It also clearly shows the mile-long spur, the 'Jubilee Course', which transects the racecourse circuit and crosses into the site of interest. This straight course was abandoned in 2006
The 1972 aerial shows gravel extraction and filling operations in the south eastern corner of the racecourse circuit (off-site). Earthworks are also evident to the south of the mile-long spur onsite - indicating that either this area has been recently stripped or recently filled. Gravel extraction has also taken place to create a water filled pit around t~ copse to the north of the site, while silt deposition appears to be in progress into another water-filled pit north of the Kempton park manor house and ancillary buildings (off-site). The 1992 aerial shows that all previously disturbed ground has been filled and returned to grassland, except for a small water-filled pit to the north of the copse. A Large water-filled pit is now also present in the northern area inside the racecourse circuit (off-site). The buildings and manor house of Kempton park to the north of the site of interest have gone.
The 1998 aerial photograph does not show anyon-site changes. The new grandstand at Kempton Park Racecourse has been constructed approximately 750m west of the site. The 2002/03 aerial photographs does not indicate any changes. By the 2008 aerial the all-weather track has been constructed.
Question 5 Underground Pipelines Please find attached a plan which shows two underground oil pipelines to the west of the site of interest. These are operated by BPA, Freephone 0800 585387. Alternatively you can make contact with the operator via Linesearch: http://www.linesearch.org/ .
Q6. Details of licences related to historical landfill in the vicinity of the site We hold index details of two historic landfills on the Kempton Park Racecourse site: one covering the bulk of the racecourse landholding; and a small on the north boundary of the racecourse, approximately 480m from the site of interest. The location and extent [please be aware that the extent shown includes the landholding of the owner/ operator and not necessarily the extent of filling - please see also question 2 for details of filling zones] of these is shown on the attached landfill plan. There are additional historic landfills from l,075m within Spelthorne Borough, details of which have not been provided at this time, but can be made available.

In addition, the site of interest is very close to the Borough Boundary with the London Boroughs of Hounslow and Richmond-upon-Thames. We are aware of a landfill known as Coombe Crescent within the London Borough of Richmond Upon Thames, at approximately 370m north east of the site of interest. The site was an unlicensed historic landfill, now Hatherop Road Recreation Ground. The Environment Agency reference is EAHLD11198 (and old EAreference of 1322), other site references of 8RI002 and RIC002, and a ERCref of 5810/0002.
Question 7 Details of any designations related to the site As per our original response we would recommend that you contact the Local Planning Authority for this information: [email protected] .
Question 8 Part A or Part B Processes There are no Part A processes within 250m of the site of interest within Spelthorne Borough. Again please be aware that the Borough boundary is in close proximity to the north and east of the site.
There is a historic Part B process at approximately 390m west: a SaveService Station (Horsepower) at 206 Staines Road East,TW16 SAY,authorisation reference 02/34. This petrol filling station operated by Save Retail Ltd closed in 2002. The permit authorised the site to operate 7 underground storage tanks (Tanks 3 to 9; 5 petrol and 2 diesel). Correspondence on the file indicates that there was a proposal in 1997 to bring back Tanks 1 & 2 into use (thought to be water-filled). These tanks were over 30 years old and single skinned. It is unclear whether this proposal proceeded. The site was redeveloped to residential units of Raphael Court in 2002/3. The planning permission, reference 02/000687, was subject to a condition (condition no. 8) requiring the developer to investigate, assessand remediate any contamination. The site investigation identified: • made ground consisting gravel/clay fill with brick, concrete and ash. Depths varied but were to a maximum level of 4.9 mbgl, but typically 3.5m thick; • Hotspots of slightly elevated levels of arsenic, TPH's, PAH's, pH, and sulphate were determined through soil sampling; • All groundwater samples were found to be clear of contamination. However, it is noted that due to practicalities the monitoring standpipes were not as close to the underground tanks as would have been ideal. A remediation strategy was agreed, and it is known that hydrocarbon contamination resulted in material removal, including excavation of soil to a depth of up to 3-3.5m bgl. Underground storage tanks and concrete were removed. Some validation information was received and the planning condition was recommended for discharge in March 2003.
There is a current authorised Part B process at approximately 450m west of the site of interest, namely the BP Kempton Park Petrol Filling Station. This site is currently authorised for two diesel and 3 petrol underground storage
90 tanks. The site has been authorised since the end of 1998. When first authorised the petrol station had four petrol tanks and one diesel tank - unfortunately I have not been able to find detail of the capacities or location of these • tanks. The file indicates that the station was redeveloped in 2002 including a new 180,000 litre tank farm comprising 3 no. 60,000 litre double skinned steel tanks, two of which were split compartment (15,000/45,000 litres), plus all new pipework and installation of a stage 1 and stage 2 vapour recovery system. I attach a copy of the Environmental Permit for the site - this includes a plan of the tank farm layout post 2002.
According to the planning database the petrol station was granted planning permission in 1967, under reference SUN/FUL/4125/U, and can be seen to be present by the 1972 aerial photograph. There was also planning permission granted in 1968 for a Lubrication, car tuning and diagnostic bay to DAH Motors (Sunbury) Ltd, under reference SUN/OUT/4125/Z5. Therefore, it is likely that even the pre-2002 current tank farm were not the original tanks. During a review of microfiche records we also found an application SUN4125T whereby outline permission was granted for the erection of a petrol filling station in March 1967 and under reference SUN4125V permission for construction of buildings and forecourt of a filling station under Building Regulations. The later contains plans of drainage and underground storage tanks. Please note that the outline application had the tank farm on the extreme north of the site (where subsequently the lubrication/ diagnostic bay was erected post 1968), but it is assumed that the Building Regulations plan (Copy attached) is the 'as-built' plan. This shows an oil store as part of the 'kiosk' building, a pump for a paraffin tank, 2x 10,000 gallon tanks under the pump islands and a 3,000 gallon DERV(diesel) tank to the north of the pump island. Such large tanks would have been unusual at that time, when 1-3,000 gallon tanks were routine, and it maybe that it was actually two tanks with a total capacity of 10,000 gallons. As outlined above by 1998 the station had one diesel and four petrol tanks.
For further information on historic tanks or in relation to storage of petroleum storage, we would recommend that you contact the Petroleum Licensing Authority at Surrey County Council:

Question 9 Status under Part 2A of the Environmental Protection Act 1990 In accordance with the Contaminated Land Inspection Strategy, Spelthorne Borough Council has reviewed information sources such as historical maps to identify land that has had a land-use that may give rise to contamination. The landfilling at Kempton Park Racecourse has been identified as part of this exercise. The Council ~ is in the process of revisiting the prioritisation of its sites and it is not possible to state what priority may be assigned to this site once this exercise has been completed. However, on the basis of available information the Council is not currently proposing to take any formal or informal action under Part 2A for this site, but this position may change in the future.
Question 10 Ground Investigation records As outlined under question 2, Appendix A of the planning application under reference 77/287 was trial bore information from boreholes drilled in 1969 and October 1976. A copy of this information is provided. The boreholes from 1969 provide depths to the clay strata, while the 1976 boreholes provide details of thickness/ depth of each strata encountered (both prior to mineral extraction and infilling).
Two site investigations were carried out by LBHWembley in December 2002 and August 2003 and consisted of five boreholes and 32 trial pits located around the perimeter of the proposed new All Weather Track. Twenty six soil samples were analysed for contamination, with two hotspots of lead and one of total petroleum hydrocarbons having been identified. Where made ground was encountered this was found to contain construction waste, timber, ash, clinker, metal, plastic, tarmac, paper, pottery, tile fragments, some asbestos and a solvent type odour. As the proposed development was for an All Weather Track the recommendation by the applicant's consultant for no specific remediation other than a watching brief was accepted. A ground gas investigation was not carried out - a 91 qualitative assessment concluded that there was a low risk from ground gas due to the nature of the fill materials encountered and the type of development proposed.
Testing of groundwater was undertaken with two samples collected from two boreholes (from BH3 and BH5) on 19 October and 15 November 2004. In the second sample slightly elevated levels of Sulphate and elevated levels of ammoniacal nitrogen were registered.
I have requested the planning file to get hold of copies of the two site investigation reports. These will be forwarded in due course. I attach a scan copy of the chapter on contamination from the Environmental Statement. I also attach a scan copy of the Statement in respect of the investigation of ground conditions and contamination, which has the groundwater sampling results enclosed.
Question 11 Geology Please find attached plans showing artificial, superficial and bedrock geology of the site and surrounding area. This data has been provided to the Council under licence from the British Geological Survey.
Question 12 Hydrogeology Please find attached plans showing aquifer status of superficial deposits and the bedrock at the site and surrounding area, together with a plan of groundwater vulnerability classification. All of this data has been made available to the Council by the Environment Agency. I also attach guidance notes prepared by the Agency explaining aquifer status classifications.
Environmental Health has record of one private water supply in the Borough. This is located 2.7km south west at Fordbridge Caravan park, Fordbridge Road, Sunbury on Thames, and is for potable supply. Our records also indicate that there was/ is a licensed water supply from a 7m deep (152 diameter) borehole at Kempton Park. Licensed __ supplies are regulated by the Environment Agency.
Question 13 Surface Water Information This question has been referred to the Council's Environment Services team for response. Any information provided by them will be forwarded shortly.
Question 14 Flooding As per our original response, this question should be directed to planning policy and the Environment Agency. "
Other information identified from microfiche records SUN/FUL/4125/L provides a plan labelling the uses of the buildings present to the east of the Kempton Park house. Unfortunately the plan does not print clearly from the microfiche record for reproduction. About half of the buildings are given as stable blocks, but there were also a canteen and stores attached to the stables, a driver's canteen, cowstalls, an implement shed, workshops and an old clockhouse.
Please do not hesitate to contact us if you have any queries with respect to the information provided. Further information including copies of the two site investigation report, and any relevant information held on surface water will be forwarded as it becomes available.
Yours sincerely, Olivia
