5. How many manhourshas this work cost to date, what is the current requirement and whatis the estimatefor the future?
6. What long-term plans, if any, exist to address problemsinany areas where problems persist? Answer

1. The Beauport site was contaminated due to the dumping of potato waste. The Crabbé site was contaminated due to the inclusion of treated construction and demolition timber being included in the composting mix.
2. The Beauport site has an ongoing regime of leachate collection and removal. The leachate is collected at the Beauport pumping station and is then pumped up to a tight tank in the Beauport car park. When the tight tank is at a predefined level a tanker is sent to collect the contents and transport them to be treated in the Bellozanne sewage treatment works. At the Crabbé site the leachate removal was stopped once the site had been cleared of compost and composted products and the site has since been remediated.
3. Private contractors have been used for leachate haulage however we are unable to provide the full financial details at the moment. This is due to the fact that the Beauport issue has been administered by different Committees and Ministries and further research will be required in order to get the actual figures.
4. There is no further anticipated leachate removal required from the Crabbé site and the leachate removal from the Beauport site will continue for the foreseeable future.
5. The leachate removal is undertaken by a contractor who charges on a per load removed basis. It is not possible to ascertain how many man hours this work has cost to date. A budget of £20,000 per year is held by TTS for leachate removal purposes however it should be noted that the actual cost will fluctuate on an annual basis due to the variance in annual rainfall.
6. C  ontamination issues will be addressed on an individual case by case basis and will be dealt by the best practicable environmental method.
