Vents from scrubbers and condensers shall be periodically monitored and maintained as per the best practicable technology.
iv) Cyanide content in the incinerator, flue gas and treated effluent shall be monitored regularly to meet the stipulations laid down by Gujarat Pollution Control Board (GPCB).HCN detectors should be provided in HCN, NaCN and Diphenyl Guanidire, (DPG) plant.
v) All the storage tanks shall be under negative pressure to avoid any leakages. Closed handling systems for chemicals and solvents shall be provided. Magnetic seals shall be provided for pumps/agitators for reactors for reduction of fugitive emissions. Chilled brine based condensers shall be used to prevent emissions. Solvent traps shall be installed wherever necessary.
vi) During transfer of materials, spillages shall be avoided and garland drains be constructed to avoid mixing of accidental spillages with domestic waste and storm drains.
vii) Fugitive emissions in the work zone environment, product, raw materials storage area etc. shall be regularly monitored with instruments of proper range. The fugitive emissions shall conform to the standards prescribed by the GPCB.

ix) The company shall upload the status of compliance of the stipulated environmental clearance conditions, including results of monitored data on its website and shall update the same periodically. It shall simultaneously be sent to the Regional office of MOEF,the respective Zonal office of CPCB and the State Pollution Control Board. The levels of SPM, RSPM, SO2, NOx and VOC (ambient levels) and HCl emissions from the stacks shall be monitored and displayed at a convenient location near the main gate of the
company and at important public places
