Appendix E.2 Manual Noise Monitoring Results for January 2004

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 June 2004. As there was no construction work in January 2004, manual noise measurements at Pak Kok Tsui residences was suspended in this reporting month.
