Impact Monitoring. ESCAPE is concerned with setting up a tailored monitoring service to track and measure the impact of the communication activities carried out. A shared dashboard will visually render all the relevant data from our communications and online activities. Necessary adjustments will be made during the course of the project. This enables identification of any deviations from KPIs in the early states, allowing adjustments to be created and contingency plans implemented. Table 16 lists all the KPIs defined for ESCAPE Dissemination plan during the project timeframe.
Impact Monitoring. The ET shall carry out impact monitoring at all designated monitoring locations for construction dust (see Table 4.1) during the entire construction period. For regular impact monitoring, the sampling frequency of at least once in every 6 days, shall be strictly observed at all the monitoring stations for 24-hour TSP monitoring. For 1-hour TSP monitoring, the sampling frequency of at least 3 times in every 6 days should be undertaken when the highest dust impact are likely to occur. Before commencing impact monitoring, the ET shall inform the IEC and ER of the impact monitoring programme such that the IEC can conduct on-site audit to ensure accuracy of the monitoring results.
Impact Monitoring. During normal construction working hour (0700-1900 Monday to Saturday), monitoring of LAeq, 30min noise levels should be carried out at the agreed monitoring locations once every week in accordance with the methodology in the TM. Other noise sources such as road traffic may make a significant contribution to the overall noise environment. Therefore, the results of noise monitoring activities would take into account such influencing factors, which may not be presented during the baseline monitoring period. General construction work carrying out during restricted hours is controlled by Construction Noise Permit (CNP) under the NCO. In case of non-compliance with the construction noise criteria, more frequent monitoring as specified in the Event and Action Plan in Table 2.3 should be carried out. This additional monitoring should be continued until the recorded noise levels are rectified or proved to be irrelevant to the construction activities.
Impact Monitoring. The ET is responsible for impact monitoring during the course of the works. For regular impact monitoring, 24-hr TSP monitoring should be in the sampling frequency of at least once every week. In case of non- compliance with the air quality criteria, more frequent monitoring exercise adopting 1-hr TSP monitoring undertaken when the highest dust impact occur, as specified in the Event and Action Plan in Table 9.3, should be conducted within 24 hours after the result is obtained. This additional monitoring should be continued until the excessive dust emission or the deterioration in air quality is rectified.
Impact Monitoring. The ET Leader shall carry out impact monitoring during the course of the Works. For regular impact monitoring, the sampling frequency of at least once in every six-days, shall be strictly observed at all the monitoring stations for 24- hr TSP monitoring. For 1-hr TSP monitoring, the sampling frequency of at least three times in every six-days shall be undertaken when the highest dust impact occurs. Before commencing the baseline monitoring, the ET leader shall inform the IEC of the impact monitoring programme such that the IEC can conduct on-site audit to ensure accuracy of the impact monitoring results. The specific time to start and stop the 24-hr TSP monitoring shall be clearly defined for each location and be strictly followed by the field operator. In case of non- compliance with the air quality criteria, more frequent monitoring exercise, as specified in the Action Plan, shall be conducted within 24 hours after the result is obtained. This additional monitoring shall be continued until the excessive dust emission or the deterioration in air quality is rectified.
Impact Monitoring. 5.7.1.1 During the dredging (both capital and maintenance) and filling operation of the Project, water quality impact monitoring should be undertaken 3 days per week, at mid-flood and mid-ebb tides, with sampling / measurement at the designated monitoring stations as shown in Table 5.1. The locations for impact monitoring should be the same as those for baseline monitoring.
5.7.1.2 The interval between two sets of monitoring should not be less than 36 hours except where there are exceedances of Action and / or Limit Levels, in which case the monitoring frequency will be increased. The proposed monitoring frequency and water quality parameters are presented in Table 5.
Impact Monitoring. During the course of the marine construction works at Aberdeen Channel, impact monitoring should be undertaken at all monitoring stations three working days per week, at mid-ebb and mid-flood tides, with sampling /measurement. The interval between two sets of monitoring should not be less than 36 hours except where the Action and/or Limit levels is/are exceeded, in which case the monitoring frequency should be increased. Two consecutive measurements of DO concentration (mgL-1), DO saturation (%) and turbidity (NTU) should be taken in-situ according to the stated sampling method. Where the difference in value between the first and second measurement of DO or turbidity parameters is more than 25% of the value of the first reading, the reading should be discarded and further readings would be taken. Water samples for SS (mgL- 1) measurements should be collected at the same depths. Duplicate water samples should be taken and analyzed. In addition to the above in-situ measurements, water temperature, pH and salinity should be determined at all monitoring stations at the same depths, as specified above. Note that in addition to the water depth, monitoring location/position, time, weather conditions, sea conditions (where appropriate), tidal stage (where appropriate), and any special phenomena should be recorded.
Impact Monitoring. Noise monitoring shall be carried out, by the ET Leader, at all the designated monitoring station. The monitoring frequency shall depend on the scale of the construction activities. The following is an initial guide on the regular monitoring frequency for each station on a per week basis when noise generating activities are underway:
a) one set of measurements between 0700-1900 hours on normal weekdays;
b) one set of measurements between 1900-2300 hours;
c) one set of measurements between 2300-0700 hours of next day; and d) one set of measurements between 0700-1900 hours on holidays. General construction work carrying out during restricted hours is controlled by CNP system under the NCO. For the measurements (b), (c) and (d) above, one set of measurements shall at least include 3 consecutive Leq(5 min) results. School exists near the construction activity, such as the Xxxx Xxxx Chi Middle School and HK Teachers Association Secondary School, noise monitoring shall be carried out during the school examination periods. The ET Leader shall liaise with the school's personnel and the Examination Authority to ascertain the exact dates and times of all examination periods during the course of the contract. In case of non-compliance with the construction noise criteria, more frequent monitoring as specified in the Action Plan in Section 3.7 shall be carried out. This additional monitoring shall be continued until the recorded noise levels are rectified or proved to be irrelevant to the construction activities.
Impact Monitoring. During the course of the river training works, monitoring shall be undertaken on three occasions per week. The interval between two sets of monitoring shall not be less than 36 hours except where there are exceedances of Action and/or Limit levels, in which case the monitoring frequency will be increased. Upon completion of all river training work, a post project monitoring exercise on river water quality shall be carried out for four weeks in the same manner as the impact monitoring. Proposed water quality monitoring schedule shall be faxed to EPD on or before the first day of the monitoring month, EPD shall be notified immediately of any change in schedule by fax.
Impact Monitoring. Traffic noise monitoring shall be carried out at the proposed monitoring stations (subject to approval by EPD) when Widening of Tolo Highway/Fanling Highway between Island House Interchange and Fanling is fully operational. It is recommended that two sets of traffic noise monitoring data should be obtained during the first year of the operation of Widening of Tolo Highway/Fanling Highway between Island House Interchange and Fanling. The following is a guide on the traffic noise monitoring for each station when Widening of Tolo Highway/Fanling Highway between Island House Interchange and Fanling is operational: • one set of measurements at the morning traffic peak hour on normal weekdays (exact timing to be confirmed with Transport Department and agreed with EPD); and • one set of measurements at the evening traffic peak hour on normal weekdays (exact timing to be confirmed with Transport Department and agreed with EPD). During the traffic noise monitoring, traffic counts (vehicles per hour, % of heavy vehicles and mean speed for north-bound and south-bound respectively) should also be conducted so as to ensure the traffic noise of the peak periods are covered. The measured noise levels should be compared with the noise modelling result obtained with the counted traffic data. The discrepancy, if any, shall be reported to EPD.
