3. I.Summary of technical guideline

4. I Summary Classification of Land in view of chemical contamination 1 Land used for agricultural purposes 2 Land used for forestry purposes 3 Land used for residential and recreational purposes 4 Land used for commercial and service purposes 5 Land used for industrial purposes Objectives Scopes - To provide detailed technical guidelines for the procedure of monitoring of the contaminated soil - Detailed technical steps for soil monitoring - Reporting monitoring data and results

5. I Summary Contaminants Maximum acceptable limit Land used for agricultural purposes Land used for forestry purposes Land used for residential and recreational purposes Land used for commercial and service purposes Land used for industrial purposes Arsenic (As)12 Cadmium (Cd)225510 Copper (Cu)5070 100 Lead (Pb)70100120200300 Zinc (Zn)200 300 + 39 pesticides including Atrazine Soil contaminants Classification of contaminated soil Soil contamination level Number of analyzed samples for heavy metal concentration in excess of the acceptable limit; % Number of parameter of chemicals in soil with concentrations in excess of the acceptable limit One parameterTwo parameter Heavy contamination> 50> 25≥ 3 parameters Medium contamination25 – 5020 – 252 parameters Mild contamination< 25< 201 parameter

6. I Summary Technical guidelines 1 Basic survey 2 General condition survey 3 Precise survey - Determine possibility of contamination - Review data, Interview and site visit, etc. - Find contaminants, overall contamination extent at subject area - Determine sampling points and analysis items depending on land uses - Delineate extent and volume of contamination based on general condition survey - Determine sampling points, depth and analysis items depending on land uses

7. II. Review

8. II Review Framework of soil environment management of Korea 1 Soil monitoring Soil measuring network (MOE) : - To monitor(identify) soil condition of whole nation - Monitoring points(fixed) are selected and soil condition is checked in every year Actual state soil survey (local government) : - To detect soil contamination of concerned area in early stage - Select concerned area (not fixed points, area) and conduct survey in every year - industrial area, mine area, waste dumping area, etc. Leakage test and soil contamination test (owner of specific facilities) - To detect soil contamination of specific facilities in early stage - Duty of owners of the facilities

9. II Review Framework of soil environment management of Korea 2 Soil survey (investigation) Detailed soil survey (Responsible party) : - To delineate extent and volume of contaminated area - Area which is identified contamination from soil measuring network, actual state of soil contamination survey, and where accidents take place Soil environment assessment : - To examine soil contamination when the site installed the specific facilities is transferred(taken over), rented(taken on lease) - Not compulsory Risk assessment : - For the area owned by nation and naturally contaminated area - Determine extent and period of remediation considering the results of risk assessment - Establish committee to verify results of risk assessment

10. II Review Framework of soil environment management of Korea 3 Verification of soil remediation and monitoring soil condition after remediation Verification of soil remediation : - To verify remediation process and remediation results - Determine number of sampling and analysis items depending on contaminated extent and remediation methods Monitoring after remediation : - For the remediated site which was or has been installed specific facilities - Check soil condition for 2 years after remediation

11. II Review Comments on the technical guidelines 1 Objectives “ to identify areas at risk of contamination or already considered as contamination ones, and to be included in the monitoring programs ” ▷ To identify areas at risk of contamination, Soil monitoring is needed such as soil measuring network and actual state survey of Korea ▷ To identify areas already considered as contamination ones, Detailed soil survey is needed (delineate the extent of contamination) 2 Monitoring area “ areas which have high potential of contamination, including factories and industries, waste landfills or incineration, metal mining, including areas where accidents and public grievances take place frequently ”. ▷ Needed to select proper monitoring area depending on its objective

12. II Review Comments on the technical guidelines 4 Others ▷ Monitoring frequency ▷ Monitoring agencies that performs sampling and analysis ▷ Criterion on management of documents 5 Following steps ▷ In case that contaminated area (Heavily, Medially, or Mildly) is identified, What is next step? How to manage the contaminated land? 3 Technical guidelines ▷ Similar to detailed soil survey of Korea ▷ Guideline to delineate the extent of soil contamination after identifying the contamination

13. III. Recommendation

14. III Recommendations - Phase-in of the soil management policy is needed. ex) from soil monitoring of nationwide & actual state survey on the risk area - Considering land uses and its area, periodically check the soil condition at the selected points ★ Useful for basic data to make policies by determining the background level of Vietnamese soil and contamination level for soil management. - This guideline can be applicable to delineate the extent of contamination - Soil contaminants Considering Vietnamese industries, more items related with oil(TPH, BTEX, etc.) and hazardous chemicals(CN, Phenol, TCE, PCE, etc.) are going to be introduced

15. III Recommendations A master plan of soil conservation in Korea (2010 ~ 2019) Vision Make healthy soil environment to achieve a green society 1 Strengthen policy of Protection of public health and precaution 2 Establish rational foundation of soil management 4 Promote the soil environment industries for green growth 5 Establish cooperative soil conservation system and international cooperation 3 Develop soil & groundwater technologies and human resources 5 Projects Key Projects Expand the nation’s role on soil remediation - Establish soil bank - Make a remediation fund, National Priority list Manage soil & groundwater together - Run soil & groundwater monitoring network - Develop system and policy Promote the soil environment industry - Research project to develop technologies - Establish and run a soil bank Expand performing a risk assessment - Make a remediation level from the assessment - Develop the technologies for risk assessment
