	Summary of Dredging Rate during this period
1.	Condition no .3.3 of the varied Environmental Permit (EP-071/2000/B)
1.1	During the ebb tide, the maximum allowable dredging rate is 52,667 m3 per day.
1.2	During the flood tide, the maximum allowable dredging rate is 40,667 m3 per day.
2.	Checking Actual Dredging Rates Against EP requirements
2.1	It is difficult to differentiate the dredging volumes during ebb and flood tides in a day.  Hence to facilitate checking the EP conditions, it is assumed that the whole operation day falls on flood tides and ebb tides.  The largest bulked volume of dredged marine muds in the reporting month is converted to the in-situ volume, which is then checked against the EP conditions.  This approach has been acceptable by EPD.
2.2	During the reporting month, the largest quantity of dredged marine mud is 4,250 m3 (bulked volume) on 1st November 2001.  Hence, the volume of dredged mud equals to (4,250/ 1.3) = 3,269 m3 (in in-situ volume) where 1.3 is a bulking factor.  This figure, 3,269 m3,  is lower than both allowable rates summarised in item 1 above.  Hence, it can be concluded that the contractor complied with the condition stipulated in the EP regarding the dredging rate.
