Optoelectronic Materials and Component Manufacturing Industry Effluent Standards

Optoelectronic Materials and Component Manufacturing Industry Effluent Standards Ten articles promulgated by Environmental Protection Administration Order Huan-Shu-Shui-Tzu No. 1010090478 on October 12, 2012. Article 1 These Standards are determined pursuant to Article 7, Paragraph 2 of the Water Pollution Control Act. Article 2 Terms used in these Standards are defined as follows: I. " 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. II. "Newly-established enterprises" means those enterprises for which planning had not been completed as of October 12, 2012, or for which planning had been completed, but project bid request procedures had not yet been completed as of that time. III. "Existing enterprises" means those enterprises that had been completed, were in construction, or for which project bid request procedures had been completed as of October 12, 2012. 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 for the water quality items and limits prescribed in these Standards. 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 competent authority 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. Attached Table Item Limit Remarks Water temperature 38 ℃ (applicable to the period from May to September) Applicable to the discharging of effluents into surface water bodies other than the ocean. 35 ℃ (applicable to the period from October to April of the following year) 42 ℃, and the temperature difference may not exceed 4 ℃ for surface water at 500 meters from the discharge point. Applicable to effluents directly discharged into the sea. pH 6.0 - 9.0 Fluorides 15 Nitrate nitrogen 50 Ammonia nitrogen 10 Applicable to enterprises discharging wastewater or sewage into water source water quality protection zones. 20 Applicable to newly-established enterprises not discharging wastewater or sewage into water source water quality protection zones. 75 1.Applicable to existing enterprises not discharging wastewater or sewage into a water source water quality protection zones; enforced from July 1, 2013. 2. When a project or other improvement measure is involved, the enterprise shall submit an effluent pollutant reduction management plan by March 31, 2013, and shall implement the content of said plan after approval by the special municipality, county, or city competent authority; enforced from January 1, 2015. 30 Applicable to existing enterprises not discharging wastewater or sewage into a water source water quality protection zones; enforced from January 1, 2017. Orthophosphates 4.0 Applicable to enterprises discharging (calculated as trivalent phosphate radicals) wastewater or sewage into water source water quality protection zones.
