Executive Summary

 

i.        The Civil Engineering and Development Department HKSAR has appointed MateriaLab Consultants Limited (MCL) to undertake the Environmental Team services for the Project and carry out the baseline monitoring.

 

ii.        This Baseline Monitoring Report presents the air quality and noise baseline monitoring works. The air quality and noise baseline monitoring was conducted from 20 January 2016 to 6 February 2016 at three monitoring locations KTD1a, KTD2a and KER1a.

iii.        The average results and Action and Limit Levels (A/L Levels) of 1-hr TSP, 24-hr TSP and noise baseline monitoring at the three monitoring locations are summarized in Table I, II and III respectively. The Action and Limit Levels for air quality impact monitoring were derived based on the criteria adopted from the EM&A Manual.
