The Monthly Air Quality Report for September 2568 of BLCP Power Station presents air quality monitoring results from both the Continuous Emission Monitoring System (CEMS) and the Ambient Air Quality Monitoring Stations (AQMS). Overall, all monitoring results are within criteria and safe for health.
For measurements from the CEMS, which monitors emissions from the power plant stacks, it was found that the values for Total Suspended Particulates (TSP), Sulfur Dioxide (SO2), and Nitrogen Oxides (NOx) were all within the standard criteria set by Thai law and EIA requirements. Specifically, TSP values were below 120 mg/m³@7%O2 and 43 mg/m³@7%O2, SO2 values were below 320 ppmvd@7%O2 and 262 ppmvd@7%O2, and NOx values were below 350 ppmvd@7%O2 and 241 ppmvd@7%O2, respectively.
Regarding ambient air quality measurements from the 4 AQMS stations surrounding BLCP Power Station, the monitoring results for September 2568 show that the values for Total Suspended Particulates (TSP), Particulate Matter less than 10 microns (PM10), Sulfur Dioxide (SO2), and Nitrogen Dioxide (NO2) were all within the standard criteria set by Thai law as well. Specifically, TSP values were below 330 µg/m³ (24-hour average), PM10 values were below 120 µg/m³ (24-hour average), SO2 values were below 300 ppb (1-hour maximum), and NO2 values were below 170 ppb (1-hour maximum).
The four ambient air quality monitoring stations used for data collection are: Station A: Wat Takuan, Station B: Soi Thoed Thai Muslim, Station C: PTT Staff Housing Fence, and Station D: Wat Mab Chalood.
In summary, the air quality from both emission sources and the ambient environment around BLCP Power Station for September 2568 is at a safe level and fully complies with all established standards. Full details are available in the attached file.
