Abstract

Because the seriousness of particulate matter (PM) is increasing along with public concern, it is necessary to strengthen the crackdown on fugitive dust at construction sites where the contribution to PM is high. In Korea, the only standard is the 'Standards for installation and necessary measures for suppressing fugitive dust generation', which covers the eleven emission processes proposed by Korea's Enforcement Regulations for the Clean Air Conservation Act. Korea’s regulations are based on the emissions process, which is connected with work places where fugitive dust emission is an issue, so the contents are insufficient and hard to link to the regulations. Regulation is required prior to strict crackdowns in order to manage fugitive dust in construction sites. These regulations are clear, specific and useful. This study analyzes the fugitive dust regulations and suggests measures for improvement.

Introduction

In light of the growing public interest in the environment, particulate matter is becoming an increasingly important issue. In recognition of the seriousness of particulate matter, the World Health Organization (WHO) proposed air quality guidelines for fine dust (PM10-2.5) in 1987, and the International Agency for Research on Cancer (IARC) designated particulate matter as a group-1 carcinogen with confirmed carcinogenic effects in humans. In Korea, since the introduction of the Total Suspended Particles (TSP) standard in 1983, the standard was changed to PM10 in 1995 and PM2.5 in 2015.

Particulate matter, which is an air pollutant, adversely affects not only environmental pollution but also the quality of life, causing damage to public health and discomfort in daily life. Fugitive dust comprises the largest portion of PM. Of all the complaints related to fugitive dust in the Seoul metropolitan area, 99.4% occur in construction projects. This shows that fugitive dust from construction work has the greatest influence on residents.

The Clean Air Conservation Act stipulates that construction sites must be in accordance with regulations for each size and type of building in terms of the management of scattered dust in construction, and proposes regulations for the prevention of fugitive dust. Local governments are conducting periodic inspections based on regulations, and taking administrative actions (e.g., improvement orders, fines, warnings, orders to implement measures, suspension of use). However, considering that the number of civil complaints related to fugitive dust is at a maximum, there is some doubt as to the effectiveness of the current fugitive dust management system and countermeasures.

One of the major causes of this problem is the ambiguity of the fugitive dust suppression regulations, particularly in their application to construction sites. In addition, there is no dedicated provision that uses construction terminology, even though construction site fugitive dust represents the largest portion of PM. This study analyzes the scattering control regulations on construction sites, and proposes some improvements.

Fugitive dust regulations on Korean construction sites

The regulation on fugitive dust at construction sites is based on Article 58-4 of the Enforcement Regulations of the Clean Air Conservation Act, 'Standards for installation and necessary measures for suppressing fugitive dust generation'. This includes eleven emission processes that generate fugitive dust and sets forth corresponding measures. In addition, if there is concern that a project may cause significant damage to the health and property of the inhabitants or the growth of plants and animals, stricter regulations may be
