The Ministry of Environment
(Minister Kim Eunkyuong) will provide an advance notice on revision of the enforcement
ordinance and the regulations of Clean Air Conservation Act for 40 days
starting from September 13th, to tighten dust scattering control in
construction facilities, which is a source of high concentrations of fine dust.
The revised law will go into
effect in 2019, and the sources of dust scattering, such as construction sites
and power plants (about 44,000 facilities across the nation, as of the end of
2017), will be subjected. This law focuses on facilities with many complaints
from local people and aims to reduce the sources of highly concentrated fine
The key material of the
revision is ① expansion of the management subjects of dust scattering sources ②
application of stricter standards for dust scattering suppression facilities
when it comes to the repainting of buildings ③ replacement of outdoor coal
depots with indoor ones, and ④ completion of equipping worn out construction
machinery with lower pollutant devices. The details are as follows:
<Expansion of the management
subjects of fine dust sources>
First, dust management
subjects will increase from the current 41 to 45 types of business.
The remodeling of apartment
buildings and farmland arrangement as well as repainting the exterior walls* of
apartment buildings will be included as the new dust scattering control subjects.
* Repainting of the exterior
walls of apartment buildings that draw up long-term maintenance programs in
compliance with “Multi-family
Housing Management Act”
Even though these projects
cause similar amounts of dust scattering to that of construction and civil
engineering works, which are currently under management, they have not been
subjected to dust management, leading to complaints from the local community.
Thus, they must be included as management subjects.
- When these projects are
included as new subjects, the construction company must notify local governments
of the projects and appropriately carry out dust management during the open
storage and transportation of materials by building wave barriers and watering
In addition, a legal basis has
been formed that requires construction works carried out within 50 meters of
living facilities, such as hospitals and schools, to be subjected to prior
notification regardless of the construction scale.
- Currently, only certain
construction projects that exceed a pre-determined scale (more than 1,000㎡ for construction works) is
subjected to dust scattering control. The revision, however, allows local
governments to actively suppress dust sources in order to protect the
vulnerable and in consideration of the potential environment impact on
surrounding areas due to constructions works.
< Application of stricter
standards for dust suppression facilities >
Stricter standards for dust scattering
(from the remnants of paint) caused by repainting exterior walls will be
adopted. Since repainting projects have not been subjected to dust scattering control,
there have been calls for introducing related policies.
From now on, not only
construction works but also repainting projects shall comply with the rules
related to dust suppression. To minimize dust scattering, dust barriers should
be installed for painting sites that use paint sprays. Also, a stricter rule
has been applied to painting sites within 50m from the boundary of living
facilities for vulnerable social groups, including hospitals and schools, to
use brushes or rollers* only.
*Rollers can reduce dust
scattering up to 90 percent in comparison to spraying. (Spraying loses 29 to 40
percent of paint; rollers lose 4 to 8 percent.)
Third, the construction of
coal depots in coal-fired plants will now be mandatory. Currently six
coal-fired plants are operating the facility. The new article prevents damages
from coal dust to people living close to the old coal-fired plants, since these
plants store coal outdoors.
Fourth, from now on, low
pollutant measures (installing gas emitting reduction devices, replacing old
engines, etc.) have to be taken in order to keep using old construction machinery
at construction sites. In the initial stage, considering the current budget to
support low pollutant measures, the new rule will be implemented only to
governmental construction projects in the Seoul Metropolitan Area worth more
than 10 billion won.
Regarding the expenses for the measures, 90 percent of them will be funded by the government to minimize the burden of the machinery owners.
Finally, the existing rules
will also be improved. For example, now the rule for dust barriers stipulates
that the open rate of the barriers should be around 40 percent in order to
maximize the deceleration effect against wind velocity.
The strengthened rules are
expected to reduce the emission of fine dust (PM10) from dust scattering in
construction sites and machinery. The current annual emission is 41,502 tons
and the expected amount of reduction is 2,702 tons (6.5 percent).
“Once emitted, dust scattering is
hard to control. So, the thorough management of emitting facilities is
important,” said Shin Gunil, Director of Air Quality
Management Division of the Ministry of Environment. “This
proposed amendment is made to minimize the emission of dust scattering to
nearby residences to protect people’s health. We hope
that each business site reinforces dust scattering management.”
The details of the amendment can be found on the website of the Ministry of Environment (www.me.go.kr). The ministry will gather the opinions of stakeholders and citizens during the pre-announcement period and reflect them in the amendment.
