Article 5 The dioxin concentration is calculated as the sum of the measured concentrations of 17 compounds, including 2,3,7,8-tetrachlorinated dibenzo-p-dioxin-2,3,7,8-TeCDD, 2,3,7,8-tetrachlorinated dibenzofuran,2,3,7,8-TeCDF and 2,3,7,8- penta-, hexa-, hepta-, and octa-chlorinated dioxins and furans, multiplied by the international dioxin toxic equivalency factors (I-TEF), and is expressed as a toxicity equivalency quantity of 2,3,7,8-tetrachlorinated dibenzo-p-dioxin quantity (TEQ). Article 6 All values of the effluent characteristics used in these Standards constitute maximum limitations, with the exception of the lowest limits for pH, and the units for such characteristics are defined as follows: I. pH: Unitless II. True color: Unitless III. E. Coli: Colony count on filter membrane per 100 ml water sample (CFU/100mL). IV. Dioxin: pg I-TEQ/L V. Other characteristics: mg/L Article 7 Apart from water temperature and pH, with regard to the limits for the various items in these Standards, these Standards shall not be applicable when an enterprise or sewage system takes non-contact cooling water from a water body for cooling or cyclic use, and discharges water into a surface water body near the original water intake location. Article 8 If an enterprise, sewage system, or building sewage treatment facility simultaneously has, within the applicable scope of these Standards, two or more different industry types or different processes within the same industry, and wastewater is mixed during treatment and discharge, effluent standards for each industry shall be complied with. When the same control items have different control limits, the stricter limits shall be complied with. When wastewater from one industry type accounts for 75% or more of all wastewater volume, and that wastewater stream is equipped with an independent, dedicated, cumulative flow measurement facility, the enterprise, sewage system, or building sewage treatment facility may apply to the competent authority to control common control items on the basis of effluent standards for said industry. The wastewater volume percentage in the foregoing paragraph shall be calculated using records from the half-year prior to the application date. Article 9 Unless an enforcement date is separately designated, these Standards shall take effect on the date of promulgation.
