In order to effectively suppress and mitigate the serious deterioration of air quality resulting from river fugitive dust, since November 2007 the Environmental Protection Administration (EPA) has invited the Water Resources Agency, Council of Agriculture, and local governments to collaboratively explore relevant issues. January 7, 2013, the “River Fugitive Dust Prevention ＆ Improvement Project” was approved by the Executive Yuan for the implementation of “River Fugitive Dust Prevention ＆ Improvement Action Plan”, and again on October 17, 2016, the “Clean Air Action Plan” was approved, empowering the central and local governments to co-work by their individual authorities to suppress the river fugitive dust.
The key items of the action plans for this year have been gradually set in place, and rolling reviews are carried out with the changes of the flood season and bare land exposure. The project will assist the EPA in conducting site surveys and convening project meetings to coordinate involving institutes on division of labor before and after the flood season, and set up prevention methods for areas vulnerable to fugitive dusts along with control schedules, in an effort to reduce the river fugitive dust.
To implement the project, measures for river fugitive dust prevention adopted at home and abroad in the U.S. and Mainland China are collected as reference for subsequent improvement on river bare lands. The ultimate intention is to restore the river ecological habitat and it ecologic corridor, achieving the goal of returning fields to rivers.
The new version of “River Fugitive Dust Prevention Online Platform” has been up and running since March 1, 2017, which provides information on the prevention jobs and results for the general public to comprehend what the governments have been doing to prevent river fugitive dust.
The local authorities of environmental protection have established standard operating procedure and contingency plans in response to the geographic nature of rivers and climate conditions of regions, along with local dust rating systems developed for local-specific early warning mechanism.
The EPA subsidizes local governments to implement the project, and also considers the effect on the locals. Since 2013 the number of days of PSI > 100 out of PM10 has been gradually reduced. And the number in 2016 further dropped vs. 2015; the number recorded at the Lunbei observatory even slipped over 50%. The figures show that the air quality of the river areas is improving.
