Article 64(2) of the former Water Quality and Aquatic Ecosystem Conservation Act (amended by Act No. 11979, Jul. 30, 2013; hereinafter “former Water Quality Ecosystem Act”) provides that “where a wastewater treatment business operator falls under any of the following subparagraphs, the Minister of Environment may revoke his/her registration or order him/her to suspend his/her business for a fixed period not exceeding six months,” and one of the following subparagraphs provides that “where a wastewater treatment business operator falls under any of the following subparagraphs, he/she may revoke his/her registration or order him/her to suspend his

In relation to the "cases of installing pipelines not necessary for wastewater treatment", the provisions stipulate that the revocation of registration in the case of the first violation shall be made for three months of business suspension and in the case of the second violation.

Therefore, the provision of the instant rule only determines matters concerning the determination of dispositions with respect to “where pipelines that are not necessary for wastewater treatment are installed,” which fall under one type of “in a case where wastewater treatment business is performed insufficiently due to intention or gross negligence.”
