3                                       HUMAN HEALTH RISK

3.1                                 Introduction

3.1.1.1                     This section presents the requirements, methodology, criteria and protocols for the measurement of human health risk impacts for this Project.

3.1.1.2                     The human health risk assessment will focus on assessing the potential health impacts due to radon emissions associated with pulverized fly ash (PFA) arising from the construction and operation of STF.

3.2                                 Monitoring of Radon Concentration

3.2.1                           Baseline Measurement

3.2.1.1                     As recommended in the EIA Report, the radon concentration shall be measured prior to the occupation of the STF buildings by professional persons in accordance with EPD ProPECC Note PN 1/99 “Control of Radon Concentration in New Buildings” to ensure that the radon concentration complies with the guideline value in EPD ProPECC Note PN 1/99.

3.2.2                           Monitoring during Operation Phase

3.2.2.1                     In the first year of operation of the STF, the radon concentration shall be measured quarterly by professional persons to confirm that the radon level complies with the guideline value stipulated in EPD ProPECC Note PN 1/99.  

3.2.3                           Measurement of Radon Concentration

3.2.3.1                     The measurement locations, measurement protocol, measurement criteria, report and documentation described in Appendix 2 of “Protocol of Radon Measurement for Non-residential Building” of EPD ProPECC Note PN 1/99 “Control of Radon Concentration in New Buildings” shall be followed.  The protocol is enclosed in Appendix 3.1 of this EM&A Manual for information.
