Air pollution controls to construction site that become institutionalized when the Environmental Protection Administration R.C.C inured the “Construction Site Air Pollution Control Facility Management Regulations” on 01/07/2004. The project of 2003 had accomplished 5680 on-site environmental inspections, and 2817 “Construction Site Air Pollution Control Facility Management Regulations” inspections. Calculated Taipei city’s particles emission from construction site according to the construction site management database system, there were 1754 tons particles released into air in 2004, and the particles decrement were 49.50%. The particles emission in 2004 were decreased about 40%, compare to 2003.
There have 6 pollution pursuance improvement conferences been proceeded, which included 121 builders been invited. The achievements of the conferences have increased the percentage of particles decrement from 52.56% to 68.27%. The acceptable ratio of “Construction Site Air Pollution Control Facility Management Regulations” hitherto is 66.16% in first-degree sites, and 55.66% in secondary-degree sites. The percentage that the builders install air pollution control facilities in Taipei city achieves the most in 2004, especially in banking.
75 construction sites have been adopted road-care program from April, 2004 to February, 2005; the entire length of roads were adopted amounted to 29.38 kilometers with 17169.5 kilometers been clean-up, and could reduce 237 tons Total Suspend Particle. Accomplished 30 in-site experiments to estimate volatile organic compounds emission rate: from water-based coating was 0.100 kg/L, from solvent-based coating was 0.501 kg/L. Accomplished 100 questionnaire responses to estimate the usage of coating: from water-based coating was 0.197 L/m2, from solvent-based coating was 0.138 L/m2. Calculated Taipei city’s volatile organic compounds emission from construction coating, there were 215.7 tons volatile organic compounds released into air in 2004.
