In the fine dust (PM10, PM2.5) that threatens life, active measures such as eliminating the source of occurrence and reducing the amount of occurrence should be given priority rather than passive measures such as wearing a mask. The construction site, which is the main source of fine dust and the main cause of environmental complaints, has made a lot of efforts to reduce and manage fugitive dust (dust including total dust, fine dust, and ultrafine dust), and the government has invested heavily in the management of fugitive dust.
However, despite the government and construction companies'' efforts to deal with fugitive dust, complaints related to fugitive dust in the construction site are increasing, and the violation rate in the case of crackdown on fugitive dust in the construction site exceeds 10%.

This study started from the idea of helping to solve the fugitive dust problem of construction site, examined the theoretical consideration, the problems of management regulations and systems, and the actual operation cases of the site, and suggested the improvement plan so that the results can be applied to the actual policy reflection.

First, the definition and classification of the terms related to fugitive dust were made through theoretical consideration, and the effects and damages of fugitive dust sources, the laws and systems related to fugitive dust in the construction site, the status of the workplace reporting dust occurrence, the status of the fugitive dust control at the construction site, and the status of the fugitive dust complaints at the construction site were investigated and analyzed.

According to the literature survey, the violation rate of the fugitive dust in the construction site in 2015 was 10.17%, and 48.36% of the violations were <inappropriate for facility standards>. The lack of understanding of related standards due to the lack of construction environmental education, the contents of <Attached Table 14>, <Attached Table 15> and the ambiguity of facility standards were presumed to be the main cause of continuous violations. The number of complaints in the scattered dust-producing workplaces is increasing day by day, and as of 2015, the construction industry (construction site) accounted for 91% of the total, with 20,797 cases, which is estimated to be <inappropriate for facility standards>.

Through these statistics, the actual application of <Enforcement Rule of the Atmospheric Environment Conservation Act> <Attached Table 14> and <Attached Table 15>, which are <Facility Standard>, were investigated, and the survey contents were analyzed into <Environment-related Law>, <Environmental Problem>, <Efficiency>, <Economicality>, and <Appropriateness>, and the following problems were suggested.
First, the problems of terms are as follows.
There is no term definition for the main discharge process, and no term definition and type of powdery matter, which is the main source of discharge, has been suggested. In the outdoor painting process, only manufacturing was mentioned, construction was not mentioned, and the definition of the fugitive dust control facility and the relevant facility were not suggested. They use non-specific and non-quantitative terms such as "maximum", "minimization", "sufficient", "as much as possible", "if possible", "such" and use ambiguous expressions such as "the facility with the same or more effect".
Second, the problems of the fugitive dust control facilities among the measures are as follows.
There is no specific standard for the dustproof cover, so the construction site is interpreted and used arbitrarily, and the dustproof wall height standard is in conflict with the soundproof wall in the noise and vibration management law. Although the aperture ratio of the dustproof network is set at 40%, the construction site still does not know the contents, and the dustproof network equivalent to the aperture ratio of 40% is difficult to purchase at the construction site because it does not know how much the aperture ratio is. Dump truck cover standards, which are powder-based material transport vehicles, are not clear, so the upper cover is often worn or torn, so fugitive dust is fugitive during transportation. There is no specific standard for the washing water, so it is polluting the surrounding roads because it is washing and side watering with turbid water without water purification.
Third, the problems caused by the lack of regulation of dust concentration in construction sites are as follows.
Since there is no concentration regulation, even if environmental disputes caused by fine dust occur, there is a limit to rescue the victims because it is difficult to clarify the causal relationship between environmental damage because there is no result of fugitive dust measurement and related administrative disposition when the administrative agency cracks down.

After investigating and analyzing not only the problems of the work standards but also the problems of the related system, the following improvement plans were suggested as a plan to reduce the dust fugitive in the construction site.
First, the improvement plan related to terms is as follows.
The definition of the terminology for the main discharge process and the main types of the discharge process were set and suggested, and the definition and type of terminology for the main discharge source, powdery matter, were suggested. The necessity of revision of related laws and regulations was mentioned in the outdoor painting process, and 42 facilities for preventing fugitive dust were classified and the term definition and the relevant facilities were specified. The improvement plans for non-specific and non-quantitative terms such as "maximum", "minimization", "sufficient", "as much as possible", "if possible", "etc." were suggested, and the improvement plans for the alternative criteria "the facility with the same or more effect" were suggested.
Second, the improvement plan of the fugitive dust control facility among the measures is as follows.
The types of dustproof cover were set up in the field and suggested to be examples in the 「Enforcement Regulations of the Air Quality Preservation Act」, <Attached Table 14> or <Fascinated dust management manual>. In case of residential commercial buildings within 50m from the boundary line of the construction site of the construction site in the city, the regulation to install the 3m high dustproof wall was proposed to be changed from the boundary line of the construction site to 300m without conflict with the noise vibration management law. It is suggested that the opening ratio of the market circulation dustproof network and shade network (light shielding film etc.) be obligated to be indicated. The standard of installation and operation of the clean water purification facility was specified and the standard of the height of the side watering facility was proposed to be strengthened. The definition of indoor painting and the necessity of specific standards for indoor painting work were suggested. The necessity of installing the fugitive dust control facility at the point exceeding 40m from the site boundary was suggested during the outdoor polishing and outdoor painting work. And it suggested the implementation of education related to the facility for preventing fugitive dust in construction site.
Third, the concentration control criteria for the fugitive dust in the construction site were divided into total dust, fine dust, and ultrafine dust, and each concentration was presented as an average of 1 hour.

More detailed investigation and research will be needed, but the Ministry of Environment needs to use this paper as a basic data to understand the characteristics of construction work and the types of construction work and to organize a research team with researchers with basic knowledge of environmental engineering to conduct field-oriented faithful investigation and research, and to revise it into reasonable, efficient and realistic laws and regulations through various opinions of related experts.

In addition, education related to fugitive dust should be regularly conducted for construction company officials and local government officials.

As a result of these efforts, the installation and operation of the fugitive dust prevention facilities will be easy in the construction site, and the fugitive dust management agencies such as local governments will be able to manage and control the map more easily. The Central and Local Environmental Dispute Resolution Committee will be able to identify the causal relationship between the damage caused by fugitive dust and will greatly help prevent disputes caused by fugitive dust. Ultimately, I am confident that it will protect the health and life of the people by reducing the generation of fugitive dust and fine dust.
