How to check the measurement results

Based on the fact that the amount of watersilver emissions is affected by the amount of watersilver in raw materials and fuels, the regulations are set as regulations that capture the average amount of emissions during normal times. For this reason, unlike other major air pollutants under the Air Pollution Prevention Act, sudden excess of standard values does not violate emission standards.
If a concentration exceeding the emission standard is detected, re-measurement is performed promptly at least three times, and all measurement results, excluding the maximum and minimum values, out of a total of four or more measurement results including the first measurement results Evaluate based on the average of the measurement results.
In addition, if the first measurement result exceeds 1.5 times the emission standard, it will be carried out within 30 days after the first measurement result is obtained, and if it is less than 1.5 times, it will be performed within 60 days. It has been.
If the evaluation after re-measurement exceeds the emission standard value, it is required to contact the local government's Air Pollution Control Law department, investigate the cause, and take measures to prevent recurrence.

Record of maintenance and management of waste incineration plants

In accordance with the provisions of Article 9-3, Paragraph 6 of the Waste Disposal and Public Cleansing Law, garbage incineration plants publish information on the status of maintenance (measurement results of soot and smoke, etc.). You can see it from the incineration plant page (link).
