Project Description
Five chimneys
from the decommissioned Tsing Yi Power Station were demolished on
15 November 1998. The project called for the demolition and removal
of all chimneys structures associated with the former oil-fired
power station. China Light & Power Company Limited (CLP) will
return part of the site to the Government and retain part of the
site. The chimneys were demolished using directional felling by
controlled structural weakening via explosives planted at the bottom
of the chimneys.
Mitigation Measures and Outcomes
-
Major conditions to reduce hazards in the environmental permit
included:
- reduction
of inventory of three ESSO Hong Kong Ltd Liquefied Petroleum
Gas (LPG) spheres to below 200 tonnes,
-
removal of all LPG road tankers from the terminal,
-
three chimney-height exclusion zones enforced to minimise the
chance of ejecta or debris hitting any spectators,
-
the nearest Mobil Oil Tank was emptied for the duration of the
felling.
-
The site was watered to reduce air emissions from the impact of
debris.
-
The nearby population protected included 1,899 persons. Population
considered in the Hazard Assessment included 8,208 persons (day)
and 7,156 persons (night) under the EIA Process.
