Abolished Date: 2017-12-25
Category: Environmental Protection Administration(行政院環境保護署)
Article 1
These Standards are determined pursuant to Article 7, Paragraph 2 of the Water Pollution Control Act.
Article 2
"TTO"means the concentrations of any of the following 30 types of chemical compounds: 1,2-Dichlorobenzene, 1,3-Dichlorobenzene, 1,4-Dichlorobenzene, 1,2,4-Trichlorobenzene, Toluene, Ethylbenzene, Chloroform, 1,2-Dichloroethane, Dichloromethane, 1,1,1-Trichloroethane, 1,1,2-Trichloroethane, Dichlorobromomethane, Tetrachloroethylene, Trichloroethene, 1,1-Dichloroethene, 2-Chlorophenol, 2,4-Dichlorophenol, 4-Nitrophenol, Pentacholorophenol, 2-Nitrophenol, Phenols, 2,4,6-Trichlorophenol, Bis(2-ethylhexyl) phthalate (DEHP), Dibutyl phthalate (DBP), Benzyl butyl phthalate (BBP), Anthracene, 1,2-Diphenylhydrazine, Isophorone, and Carbon Tetrachloride.
Article 3
These Standards are applicable to Optoelectronic Materials and Component Manufacturing Industry announced as regulated in the enterprise classification and definitions of the Water Pollution Control Act.
Article 4
See the Attached Table 1 for the water quality items and limits prescribed in these Standards.
For the enterprises discharging wastewater to the special receiving water body in the water pollution total quantity control zone (“total quantity control zones” in brief) that has been announced by the special municipality, county or city competent authority for protecting the farmland water body, the regulations in Table 2 shall be applicable to the limits of copper, zinc, total chromium, nickel, cadmium and hexavalent chromium in the effluent. The regulations in table 2 shall not be applicable for the enterprises in the total quality control zones if the wastewater is discharged at a discharging point outside the total quality control zone through the attached pipelines along irrigation canals and all classes of water drainage channels, or jointly discharged through the pipelines, or if the wastewater is discharged at a discharging point in the total quality control zone but not to the special receiving water body.
Article 5
The industries, their associations, or relevant environmental groups may submit detailed scientific data and information to the Responsible Agency at the central government level to support argument for revision of these Standards.
Article 6
The COD limits determined in these Standards shall be tested using the potassium dichromate oxidation method; the true color shall be tested using true color colorimetry.
Article 7
Concerning the limits in the foregoing paragraph, apart from the pH, which is defined as a range and not in units, the rest are defined as the maximum allowed value using the following units of measure:
I. Water temperature: Celsius (℃)。
II. True color: Unitless
III. Other items: Milligrams per liter (mg/L)。
Article 8
With regard to the limits for the items in these Standards, apart from water temperature and pH, these standards shall not apply when an enterprise obtains water from a water body for non-contact cooling or circulating cooling and such water is discharged to the surface water body from which it was originally obtained.
Article 9
When an enterprise belongs to two or more industry types or belongs to one industry type but operates different production processes, the mixing, treatment and discharge of wastewater shall comply with the effluent standards for each industry type.When identical control items have different control limits, effluent shall comply with the stricter of the two limits.When the quantity of wastewater from one industry type is 75% or more of the total wastewater quantity from all industry types and independent cumulative measuring equipment has been installed, the enterprise may apply with the competentauthority to make the effluent standards of the said industry type the basis for all control items.
The percentage of wastewater as stated in the foregoing paragraph shall be calculated according to records starting from six months prior to the date of application.
Article 10
Unless an enforcement date is separately designated, these standards shall take effect on the date of promulgation.
