* The existing plant shall comply with norms for dioxins and furans as 0.1 ng/TEQ/Nm3 within 5 years from the date of notification. Notes :

i. All monitored values shall be corrected to 11% oxygen on dry basis.

ii. The CO2 concentration in tail gas shall not be less than 7%.

iii. In case, halogenated organic waste is less than 1% by weight in input waste,

all the facilities in twin chamber incinerator shall be designed so as to achieve a minimum temperature of 850±25°C in primary chamber and 950°C in secondary combustion chamber and with a gas residence time in secondary combustion chamber not less than 2 (two) seconds.

or

all the facilities in single chamber incinerator for gaseous hazardous waste shall be designed so as to achieve a minimum temperature of 950°C in the combustion chamber with a gas residence time not less than 2 (two) seconds.

iv. In case halogenated organic waste is more than 1% by weight in input waste, waste shall be incinerated only in twin chamber incinerators and all the facilities shall be designed to achieve a minimum temperature of 850±25°C in primary chamber and 1100°C in secondary combustion chamber with a gas residence time in secondary combustion chamber not less than 2 (two seconds).

v. Scrubber meant for scrubbing emissions shall not be used as quencher.

vi. Incineration plants shall be operated (combustion chambers) with such temperature, retention time and turbulence, as to achieve Total Organic Carbon (TOC) content in the incineration ash and residue less than 3%, and their loss on ignition is less than 5% of the dry weight. In case of non-conformity, ash and/or residue shall be re-incinerated.

vii. The incinerator shall have a chimney of at least thirty metre height.

B. Effluent from Incinerator

i. Effluent from scrubber (s) and floor washing shall flow through closed conduit/pipe network.

ii. Storm water shall not be allowed to mix with scrubber water and/or floor washings.

iii. Storm water shall be channelized through separate drains passing through a HDPE lined pit having holding capacity of 10 minutes (hourly average) of rainfall.

iv. The built up in Total Dissolved Solids (TDS) in wastewater of floor washings shall not exceed 1000 mg/l over and above the TDS of raw water used.

v. Effluent shall not be stored in holding tank(s) in such manner which may cause pollution to groundwater."

vi. Effluent (scrubber water and floor washings) shall be discharged into receiving water conforming to the norms prescribed under Schedule VI: General Standards for Discharge of Environment Pollutions (Part A: Effluents) notified under the Environment (Protection) Rules, 1986".
