These Standards are determined pursuant to Article 32, Paragraph 3, of the Water Pollution Control Act (herein referred to as this Act).
Soil treatment as referred to in these Standards means methods for the discharge of wastewater or sewage via pipelines or canals for irrigation or percolation into the soil for the removal or reduction of pollutants.
The following enteprises or wastewater sewage systems may use soil treatment:
Suspended solids
Aquaculture industry: limited to freshwater aquaculture
Zoos
Public Sewage Systems
Soil treatment shall not be adopted in the following areas:

Enterprises or sewage systems shall adopt water pollution control measures when they apply for a soil discharge permit. Those that discharge wastewater or pollutants into a surface water body shall acquire a surface water body discharge permit or simple discharge permit (herein referred to as a discharge permit). At the same time they shall also submit an industrial waste disposal plan for review pursuant to the Waste Disposal Act. Enterprises that dispose of wastewater or sewage using methods other than pipelines or drainage canals that are not in compliance with effluent standards, such as the use of water trucks or water tanks for the disposal of wastewater or sewage in an area outside the range of operations, shall provide a photocopy of their industrial waste disposal plan.
Enterprises subject to Article 13, Paragraph 2, of these Standards (herein referred to as enterprises whose water pollution control measure plan require initial review and approval) that are applying for a soil discharge permit shall submit their water pollution control measure plan to the local competent authority; the plan must be approved by the local competent authority before construction or devices for water pollution control measures may be initiated, pursuant to the regulations for water pollution control measure plan and permit application and review.

The contents of information and related documents on water pollution control measures shall include the following items:
Relevant test reports for soil and sewage
The foregoing paragraph applies to enterprises required to submit a water pollution control measure plan. Once the enterprises or sewage systems receive approval for the construction projects detailed in the water pollution control measure plan they shall request a soil discharge permit by filling out the application form and attaching the following documents:
For enterprises subject to the foregoing article required to submit a water pollution control measure plan, in the case where any enterprises previously operating in the same land section violated the regulations of these Standards up to a year prior to the application date for the water pollution prevention measure plan, and were ordered by the competent authority to suspend work or suspend business and then announced an internal suspension of work or business before the deadline for improvements, or in the case where enterprises previously operating on the same land section were discovered to have rerouted discharge, shall provide photographs of the completed installation of water measurement devices measuring total volume, an automatic water quality monitoring system, and a video monitoring system.For public sewage systems or enterprises that do not need to submit a water pollution control measure plan, in the case where any enterprises previously operating in the same land section violated the regulations of these Standards up to a year prior to the application date for the water pollution prevention measure plan, and were ordered by the competent authority to suspend work or suspend business and then announced an internal suspension of work or business before the deadline for improvements, or in the case where enterprises previously operating in the same land section were discovered to have rerouted discharge, the foregoing requirements also apply.
