The Clean Air Conservation Act was amended (Act no. 16306; promulgated on April 2, 2019; to be enforced on April 3, 2020) to prescribe real-time disclosure of measurement results from tele-monitoring systems (TMS) installed in air pollutant-emitting facilities. Accordingly, this Amendment prescribes matters delegated by the Act, such as the content and method of the disclosure of TMS measurement results. It modifies the calculation rationale for excess emissions charges, and adds cases where a business entity has falsely submitted its actual emission quantity to the list of reasons allowing the adjustment of charges. It prescribes grounds on which to reduce or waive basic charges for the emission facilities of places of businesses that have formulated an air pollutant reduction plan and have entered into an agreement with the Minister of Environment on the implementation of the plan. It prescribes grounds on which to process resident registration numbers and other unique identifiable information to ensure the efficient operation and management of the motor vehicle exhaust gas classification system, and otherwise addresses and improves upon a number of weaknesses that have emerged from the operation of the current system.
