It is forbidden to allow discharge of wastewater into the environment if suspended solids in the wastewater settles down at 0.4 mm/sec while in the water body settlement speed is 0.2 mm/sec. No signs of oil products, oils, fats, or other floating substances are Floating substances permissible on the surface of water No odor, taste and color transmissible to fish meat are permissible in Color, odor and taste the water Water temperature of receiving body must not be increased by more than 50C in comparison with natural temperature of water body. Water Temperature for fish living in relatively cold water bodies must Temperature not exceed in summer 20°C in winter 5°C. In other water bodies, water temperature must not exceed 28°C in summer and 8°C in winter. Dissolved oxygen content Must be above following indicators in winter season : 6 mg/l 4 mg/l The dissolved oxygen content should not be less than 6 mg/l in summer in all water bodies pH Must be between 6.5 and 8.5 BOD5 (20°C) must not increase the BOD5 of the water body by more than 3,0 mg/l. However, if the dissolved oxygen content of the water body exceeds BOD 5 6.0 mg/l (for Category I) and 4.0 mg/l (for category II), it is acceptable that wastewater flows which do not have an impact on these indicators be discharged into the water bodies. Discharge of toxic substances which have harmful effect on fish, Toxic substances aquatic organisms or their feeding source are not allowed Table 2: General requirements of quality of water body after discharge of effluents December 2009 Seureca - ASPI 4 Environmental Impact Assessment study for Hovsan Wastewater Treatment Plant Sea Outfall Construction Section 2 : Appendices Maximum No Parameters Units concentration 1 Ammonia mg/l 0,05 2 Benzol mg/l 0,5 3 Boric acid mg/l 0,1 4 Hexachloran mg/l Prohibited 5 Dissolvent mg/l 0,9 6 Cadmium (Cd2+) mg/l 0,005 7 Cobalt (Co2+) mg/l 0,01 9 Magnesium (Mg2+) mg/l 50,0 9 Copper (Cu2+) mg/l 0,01 10 Arsenic mg/l 0,05 11 Nickel (Ni2+) mg/l 0,01 12 Oxidized oil acids mg/l 3,9 13 Petrolatum (paraffin and ceresin) mg/l 6,5 14 Lead (Pb2+) mg/l 0,1 15 Free chlorine (Cl-) mg/l Prohibited 16 Zink (Zn2+) mg/l 0,01 17 Carbon sulphide mg/l 1,0 18 Cyanide mg/l 0,05 19 Trichlorfon mg/l Prohibited 20 Formalin mg/l 0,25 21 Alkil sulfonate mg/l 0,5 22 Prime alkyl sulfate mg/l 0,2 23 Carbomol mg/l 1,0 24 Metazine mg/l 1,0 25 Chromolan mg/l 0,5 26 Xylene mg/l 0,05 27 Styrene mg/l 0,1 28 Toluene mg/l 0,5 29 Oil and oil related products mg/l 0,05 30 Phenol mg/l 0,001 Table 3: Toxic substances requirements of quality of water body after discharge of effluents December 2009 Seureca - ASPI 5 Environmental Impact Assessment study for Hovsan Wastewater Treatment Plant Sea Outfall Construction Section 2 : Appendices For Hovsan WWTP, based on the above mentioned charts, the regulation is as follows : Parameter Unit Permissible level pH 6.5 - 8.5 NH4 mg/l 0.5 NO2 mg/l 0.08 Suspended Solids (SS) mg/l 4.25 SSAM (synthetic surface Active mg/l 1.0 substances) Oil and grease mg/l 0.6 BOD5 mg/l 3 Table 4: Regulation applicable to Hovsan WWTP effluent December 2009 Seureca - ASPI 6 Environmental Impact Assessment study for Hovsan Wastewater Treatment Plant Sea Outfall Construction Section 2 : Appendices Appendix 1.3 : Standards for water quality of irrigation water December 2009 Seureca - ASPI 7 Environmental Impact Assessment study for Hovsan Wastewater Treatment Plant Sea Outfall Construction Section 2 : Appendices Appendix 1.4 : Main wastewater collectors and their catchment areas within Baku City December 2009 Seureca - ASPI 8 Environmental Impact Assessment study for Hovsan Wastewater Treatment Plant Sea Outfall Construction Section 2 : Appendices Appendix 1.5 : Characteristics and map of main storm water drainage networks Average flow N° on Total Discharge Name of collector Dimensions Location discharge at map length point storm collector 700 mm 1 Aziz Aliyev (Niyazi) 889 m Akhundov garden – A.
