TECHNICAL REGULATION2.1. The allowable maximum value of pollution parameters in industrial wastewater is calculated as follows:Cmax = C x Kq x Kf where:- Cmax is allowable maximum value of the pollution parameter in industrial wastewater discharged into receiving facilities, measured in milligram per liter (mg/l);- C is value of pollution parameter in industrial wastewater stipulated at section 2.3- Kq is discharge coefficient/volumetric capacity of the receiving facilities stipulated at section 2.4- Kf is discharge coefficient of wastewater source stipulated at section 2.52.2. Cmax = C (without coefficient of Kq and Kf) is applied to parameters: temperature, pH, odour, colour, Coliform, Gross activity and gross activity 2.3.

If there is no data on flow discharge of river, stream, spring, canal, channel, streamlet, rillet the value Kq=0,9 shall be applied or Department of Natural Resource and Environment managing areas where wastewater-discharging sources are located shall appoint a unit with appropriate function to define average discharge during 03 driest of year for the basis of selecting coefficient Kq2.4.2. Coefficient Kq corresponding to volumetric capacity of wastewater receiving facilities which are reservoir, lake, pond and swamp is stipulated at the table No. 3 below:Table 3: Coefficient Kq of reservoir, lake, pond, swamp Volumetric capacity of wastewater receiving facilities (V)Calculated unit: cubic meter (m3)Coefficient KqV 10 x 1060,610 x 106 100 x 106 1,0Q is calculated in average value of volumetric capacity of eservoir, lake, pond and swamp during 03 driest months of 03 successive years (data issued by meteorological-hydrological agency). If there is no data on volumetric capacity the value Kq=0,6 shall be applied or Department of Natural Resource and Environment managing areas where wastewater-discharging sources are located shall appoint a unit with appropriate function to define average value of volumetric capacity during 03 driest of year for the basis of defining coefficient Kq2.4.3.
