2.1.3. The effluent of natural rubber processing industry discharged into the waste water disposal system of an urban or residential area where none of centralized wastewater treatment plants is developed shall apply the value Cmax = C stipulated at the column B, Schedule 1.
2.2. The value C used as the basis for calculating the maximum permissible value of parameters of pollutants
Schedule 1: The value C used as the basis for calculating the maximum permissible value of parameters of pollutants in the effluent of natural rubber processing industry
No. | Parameter | Measurement unit | Value C | ||

2 | BOD5 (20°C) | mg/l | 30 | 50 | |
3 | COD | New facility | mg/l | 75 | 200 |
Existing facility | mg/l | 100 | 250 | ||

The column A of Schedule 1 displays the value C of parameters of pollutants in the effluent of natural rubber processing industry discharged into the water sources used for the purpose of supplying water to daily human activities;
The column B of Schedule 1 displays the value C of parameters of pollutants in the effluent of natural rubber processing industry discharged into the water sources which are not used for the purpose of supplying water to daily human activities;
The use purpose of the receiving water is determined at the wastewater receiving facility.
As from January 1, 2020, the statutory value applied to new facilities shall be so applied to all natural rubber processing facilities.
2.3.Coefficient of the receiving water Kq
2.3.1. The coefficient Kq equivalent to the flow of water in rivers, streams, channels, canals and ditches stipulated by Schedule 2 as follows:

Q ≤ 50 | 0.9 |
50 < Q ≤ 200 | 1 |
200 < Q ≤ 500 | 1.1 |
Q > 500 | 1.2 |
Q is calculated by determining the mean value of the flow of the receiving water observed in 03 driest months of 03 successive years (data provided by the meteorology and hydrology center).
2.3.2. The coefficient Kq equivalent to the volume of the receiving water in lakes, ponds and wetlands stipulated in Schedule 3 as follows:
Schedule 3: The coefficient Kq equivalent to the volume of the receiving water
The volume of the receiving water (V) Measurement unit: cubic meter (m3) | Coefficient Kq |

10 x 106 < V ≤ 100 x 106 | 0.8 |
V > 100 x 106 | 1.0 |
V is calculated by determining the average value of the volume of the receiving water in lakes, ponds and wetlands during 03 months when the lowest water level is recorded in 03 successive years (based on the data provided by the meteorology and hydrology center).
2.3.3. If the receiving water is not given the data about the flow of receiving water in rivers, streams, canals, channels and ditches, the coefficient Kq = 0.9 shall be applicable; If the receiving water is not given the data about the volume of receiving water in lakes, ponds and wetlands, the coefficient Kq = 0.6 shall be applicable.
