Introduction of Voluntary Agreement
Though the emission of air pollutants is significantly improved with the effort of government, citizens and organizations, degressive environment that the civilians felt does not seem to be satisfactory. Therefore, organizations need to set up the goal by themselves to reduce the air pollutants and try hard to reduce the emission of air pollutants during the agreed period of time, which is called a Voluntary Agreement.
Until now, there were Voluntary Agreements with 4 areas such as Gwangyangman, Ulsan area, Daesan/Dangjin area and Shipbuilding industry VOC. They made an agreement for 5 years period from the year 2006 or 2007 to promote the air pollution reduction. They made an agreement with Gwangyangman, the air preservation special countermeasure area and Ulsan, the biggest industrial area in Korea in 2006, and they set up business places reduction goal for the VOC substances in Daesan/Dangjin area and Shipbuilding industry in 2007.
Reduction of Air Pollutants Emission through Voluntary Agreement
The Ministry of Environment evaluates the execution results for the Voluntary Agreement business places, and as a result of evaluation, all of the 4 Voluntary Agreement were analyzed to have a significant air pollution reduction effect during 2006~2011.
The execution evaluation for the Voluntary Agreement is consisted of 3 stages such as the Ministry of Environment self evaluation, evaluation by specialists and evaluation by statistics based on the report that the business places submit. The evaluation is focused on the points that if the air pollution substances reduction goal was achieved, investment for the reduction project, efforts of the business places for the reduction of emission, effective investment rate and efficiency of the environmental investment. During the Voluntary Agreement period, NOx from Gwangyangman, Dust from Ulsan, VOCs from Dasan/Dangjin were reduced significantly and the reduction rate by each area is that goal 13% → actual 15% for Gwangyangman, 15% → 18% for Ulsan, 18% → 17% for Dasan/Dangjin and 30% → 49% for Shipbuilding industry VOCs, which means that most of the areas achieved the reduction goal and the air quality of the areas was improved significantly.
In addition, in order to reduce the emission of air pollutants, the Voluntary Agreement business places invested more than KRW 6,500 billion for the environmental facilities such as desulfurization & denitrification facility, dust collecting system, fuel change, Regenerative Thermal Oxidation (RTO) and Leak Detection and Repair (LDAR) etc.
As a result of promotion of Voluntary Agreement, though the reduction effect of the air pollutants is very good with the aggressive participation of the organizations concerned and civilians care and support of government, the Ministry of Environment judges that there is more chances to reduce the pollution substances in the future. In order for this, the Ministry of Environment is deducing the reduction goal that fits to the characteristics of each local area based on the 1st stage evaluation result and promoting the 2nd stage Voluntary Agreement with Gwangyangman and Ulsan area during the period of 2012 ~ 2016 through close cooperation, and is trying to improve the clean and clear air quality continuously by making an agreement with Shipbuilding industry VOC.
Regulation by Each Area
VOCs regulating area can be distinguished as ‘Special Countermeasure Area’ and ‘Air Environment Regulation Area’ and the management target will be different by each area. As a ‘special countermeasure area’, Yeosu industrial complex area has been regulated since 1996 and Ulsan & Mipo Industrial complex has also been regulated since 1997. Starting from January 2001, laundry, warehousing & storage, waste storage & processing facilities have been added to the regulation targets. In air environment regulation areas, the regulation requires the measures for the suitable prevention & control facilities such as sealing, Local Ventilation Equipment, VOCs prevention facilities etc. As of 2012, 11 types of business such as petroleum refining, petrochemistry manufacturing, oil reservoir, gas station and laundry are included in this regulation target.
Reduction of Paint VOCs
The VOC emission from organic solvents covers more than 60%, which needs to have a systematic management measure and the plan for the reduction of VOCs in organic solvents area was established in May of 2003.
As a part of the plan, the policy to reduce the organic solvent in paint was promoted. 7 major domestic paint manufacturers made the voluntary agreement and had the manufacturers reduce the content of the organic solvent voluntarily. On the other hand, in order to expand the low VOC paint market, criteria for the VOC content was set in 2005 for the paints supplied to the capital area, and the standard to be appled in 2010 was prepared in 2007. Also, the VOC regulation target materials to be applied to the VOC content standard in paint was changed from 37 kinds to TVOC (Total VOC) on July 1, 2009.
In the meantime, the Clean Air Conservation Act was passed the Assembly plenary session (May 2, 2012) and the VOC content standard will be expanded to the whole nation around June of 2013. Also, the VOC content standard for the paint for shipbuilding will be prepared separately to reduce the VOC emission from the organic solvents.
VOC Reduction from Gas Station
In order to reduce the VOC generated from the gas station, the preventive facilities (Oil mist recollecting facility) for Stage I (the stage from the manufacturing facility to the storage facility in gas station) was completed by the end of December 2004, and the preventive facility for the Stage II (from the storage facility to the fuel tank of vehicles) became compulsory in 2007 and the oil mist recollecting facilities were installed from 2008 to 2012 in stages depending on the gasoline sales amount.
Also, ｢Clean Air Conservation Act｣ will be modified to install the Stage Ⅰ and Stage Ⅱ preventive facility from 2015 to 2019 for the gas stations located in over 500,000 population mid & large cities besides the environment regulation areas and special countermeasure areas, and this will be expanded to the other areas as well.
