Water Pollution Control Measures and Test Reporting Management Regulations Article 49-3

In the event that, during the construction, sludge deposits clearly visible have been formed at the bottom of pipelines in the surrounding ditches, the entry point of the water body, and its surrounding areas at the construction site, the owner shall remove the sludge deposits on its own initiative or within three days pursuant to the order of the competent authority.The owner shall use appropriate storage equipment to collect and treat the waste oil, lubricant, and diesel fuel left or spilled from construction machinery and vehicle servicing and/or maintenance, and shall not discharge or have them spill over into the place outside the work environment along with the wastewater or sewage or runoff wastewater.For the removal of sludge deposits and the collection and treatment of waste fuel and oil referred to in the preceding two paragraphs, the owner shall record the time and method for each removal, collection and treatment, and the record as well as the certificate of appropriate treatment shall be retained for reference until the construction is completed and the control under the Act is removed by the municipality or county (city) competent authority.
