WRITTEN QUESTION TO THE MINISTER FOR TRANSPORT AND TECHNICAL SERVICES BY DEPUTY G.C.L. BAUDAINS OF ST. CLEMENT
ANSWER TO BE TABLED ON TUESDAY 1st JULY 2008
Question
Would the Minister advise what information, if any, the Transport and Technical Services has received during negotiations with the Jersey Electricity Company on the use of the chimney at La Collette with regard to –
- how often it has a full internalinspection;
Answer
The Jersey Electricity Company carry out monthly visual inspections of the chimney using Jersey Electricity Company staff. In addition the Jersey Electricity Company routinely undertakes a thorough inspection of the chimney using a third party specialist. This is typically carried out on a 5 yearly basis, unless the monthly inspection identifies an issue which brings the detailed inspection forward. In 2006 TTSD, in conjunction with Jersey Electricity Company, commissioned Delta International to undertake a thorough inspection and testing of the chimney and flues. In addition, the Jersey Electricity Company provided the report from a similar inspection carried out in 2003.
Question
- approximate annual maintenance costs;
Answer
Indicative historic annual operation and maintenance costs have been provided by the Jersey Electricity Company in the development of the proposed agreement between Jersey Electricity Company and TTSD, which will enable the proposed new Energy from Waste plant to utilise existing flues in the Jersey Electricity Company's chimney. These included the costs associated with the inspection of the chimney and cathodic protection system. These costs are the property of the Jersey Electricity Company and the Minister regrets that he is unable to release the financial details of a third party.
Question
- its present age and expected lifespan.
Answer
The chimney was built in 1967. Copies of the original drawings for the construction of the chimney have been made available to TTSD and their technical consultants. The reports from the two inspections carried out in 2003 and 2006 identified that in general the chimney was in good condition and not in need of any particular remedial works. The reports do not estimate the future life of the chimney and serve as a record of the condition of the plant. The condition of the plant has not changed significantly in the period between the two inspections. The Jersey Electricity Company currently consider that with an appropriate maintenance and inspection regime, the chimney will continue to be operational throughout the life of the proposed Energy-from-Waste plant.
