On Monday, November 27, 2023, from 10:00 AM to 12:00 PM, the Working Group for Monitoring Environmental Impact Mitigation Measures of BLCP Power Company Limited's Coal-Fired Power Plant Project and Coal Transshipment Port Project held its 6/2566 meeting at the Generator Meeting Room (Room 101), Administration Building, BLCP Power Station. Mr. Damnern Sarasee, acting on behalf of the Committee Chairman, presided over the opening of the meeting. The meeting acknowledged and approved the minutes of the 5/2566 meeting, which was held on Friday, September 29, 2023.
Mr. Pachara Chuathong from BLCP Power Station presented the environmental impact monitoring results for the project during September-October 2023. It was found that 5 coal transshipment vessels docked. The sulfur content ranged from 0.36-0.43%, which did not exceed the 0.70% limit specified in the EIA report, and the cumulative average was 0.42%, not exceeding 0.45%. Electricity generation from Unit 1 ranged from 483,195-499,361 MW, and from Unit 2 ranged from 483,009-498,801 MW. The average raw water consumption was 678.55-1,048.70 cubic meters/day. All treated wastewater met the specified standards.
Regarding waste management during September-October 2023, the volume of non-hazardous waste ranged from 61.55-63.67 tons, and hazardous waste ranged from 4.00-5.08 tons. Fly ash was transported approximately 40-50 trips per day, and bottom ash approximately 9 trips per day, to cement factories for use as raw material.
Air emission quality monitoring results for September-October 2023 showed that sulfur dioxide and nitrogen dioxide levels from both generating units were within the EIA standards. An exception was noted for particulate matter from Unit 2, which temporarily exceeded EIA standards on September 7, 2023, due to a malfunction of the Electrostatic Precipitator (EP). However, the project closely monitored and supervised the situation. Additionally, the 24-hour average concentration of total particulate matter at Station C, PTT Staff Residence, was higher than normal for one day due to a wet filter paper, but the recorded values still complied with the specified standards.
During the meeting, it was clarified that coal-fired power plants typically have higher sulfur dioxide emissions than natural gas power plants due to the sulfur content in coal. Differences in coal quality used in each generating unit also lead to variations in sulfur dioxide emission levels. Nevertheless, the power plant has a maximum sulfur content specification for coal not exceeding 0.70% and a sulfur dioxide emission rate not exceeding 262 parts per million.
For the November 2023 monitoring of compliance with environmental impact prevention and mitigation measures, photos of on-site inspection activities were presented. Some attendees were observed wearing safety helmets in the power plant area and at the coal stockyard. The next meeting (1/2567) was scheduled for January 2024. Full details are in the attached file.
