Appendix E.2 Manual Noise Monitoring Results for June 2002

The hoarding works for the construction of transmission system at Pak Kok Tsui were completed on 11/5/2002. The civil works would tentatively commence in November 2002. As there would be no construction work during the period from 12/5/2002 to November 2002, the manual noise monitoring at Pak Kok Tsui would temporarily be suspended within this period.
