Dear Ms Creasy
The construction of a temporary basketball training venue by the Olympic Delivery Authority at Leyton Marsh, Lea Bridge Rd, London E10 7QL Thank you for your email of 21 May 2012 and we understand your concerns about the works taking place at Leyton Marsh.

As a statutory consultee during the planning process we had full contact with the London Borough of Waltham Forest (LBWF) and the Olympic Delivery Authority (ODA) and their consultants, to better understand the works that would be taking place on site and any possible issues.

LBWF are responsible for considering the risks to human health and contamination. They advised us that they approved additional excavation as a non-material amendment to the original planning permission on 5 April 2012 (Local Planning Authority ref: 2012/0359). We would not expect to be consulted for an amendment. I would recommend that you contact them for further information regarding reports of asbestos on the site. The Development Manager is Terunesh McKoy, who you can contact at terunesh.mckoy@wathamforest.gov.uk. The ODA have recently provided an email update to Environmental Health officers in the local boroughs, outlining their response to local concerns which had been forwarded to their Head of Health and Safety and to the Health.and Safety Executive. The update referred to the results of sampling of the stockpiled material and stated that the healt~J risks to the workforce, working on and adjacent to the stockpiles, is negligible and that off-site the risks are too low to calculate.

The ODA outlined an ongoing management programme to deal with the stockpiled material and address any residual risks. If you would like any further information from the ODA, you can contact Mark Sorrell at mark.sorrell@london2012.com.

We have reviewed the results of the sampling of the stockpiled material to assess the risk to the water environment. The excavated material does not represent a significant risk to the River Lea or to groundwater. As part of our regulatory duties we visited the site on 14 March 2012 to inspect the stockpiled material. From reviewing the results of the sampling of the stockpiled material, we were aware of traces of asbestos. We advised the contractor of the following Environmental .Permitting requirements:

** The treatment of asbestos would either require an Environmental Permit, or the employment of a company with a Mobile Treatment Permit to carry out the work. The re-use of treated waste on site would also require an exemption or permit. If the stockpiled material is to be removed from the site, the removal of asbestos would determine whether or not the waste was classified as hazardous or non- hazardous. Following your email we have spoken to the site contractors and they do not intend to treat or reuse the waste soil on site, therefore they require no permits from us. This means that the waste soil pile will need to be treated as hazardous waste due to the trace contamination of asbestos. We are satisfied that the contractors understand this and have identified a suitable site, that can accept hazardous waste, for it to be removed to. We are currently awaiting a time schedule for when this will happen. In the mean time the site has covered the waste soil pile to minimize the dust escaping from the site to the surrounding area. We have been made aware of an incident involving a resident's dog with an injury to its mouth and ears, following a walk last Sunday in the area around the basketball court building site. As the dog seemed to gain these injuries from playing in the marshland near the site, we visited the site on Tuesday to do an inspection of the surrounding area and take water samples. We observed in the area described as where the dog played, two large clumps of Giant Hogweed which when touched or chewed would produce symptoms similar to chemical burns in humans. We are still waiting for full results of the sampling but have informed Lee Valley Park, who own the land, of our findings. You can contact Martin Page at Lee Valley Regional Park Authority on 01992 709917.

If you would like to discuss any of the above, please do not hesitate to contact me at the address below.

Yours sincerely
