This plan focuses on Tainan people own and people carry streets float dust sweeping to do the watching control, and use TSP inspection to see the influence for air quality of streets float dust sweeping to provide people more comfortable environment. This project is from the date of contract 2002 December 27 to 2003 March 31. And the major contents are: (1) Check the quality of every street’s sweeping achievement (rate of achievement 100%), (2) Statistics all streets sweeping result (rate of achievement 100%), (3) Survey (rate of achievement 108.9%), (4) Sample roads control and inspection (rate of achievement 100%), (5) Do the TSP inspection before and after streets sweeping (rate of achievement 100%), (6) The amount of sweeping cars collect the dust (rate of achievement 100%), (7) The estimate of the float dust emission in the road (rate of achievement 100%), and all attend to the purpose. The estimate of this sweeping project are: (1) Emission coefficient: TSP is 400.15 ton and PM10 is 75.15 ton of sweeping streets. (2) Float dust emission: Before sweeping the TSP is 644.49 ton/year, and PM10 is 217.82 ton/year; after sweeping TSP is 466.69 ton/year, and PM10 is 167.53 ton /year. So follow the result of sweeping, this project provides the line later and the suggestion of fixing.
