Chemicals Manufacturing Industry

+ The Bioassay test shall be conducted as per IS : 6582-1971.

Note:

(i) Industries covered under this group include halo aliphatics, piasticizers, aromatics (alcohols, phenols, esters, acids and salts, aldehydes and ketones), substituted aromatics, aliphatics (alcohols, esters, acids, aldehydes, ketones, amines and amides) and detergents. 

(ii) Though norms for COD are not mentioned here but, COD shall be monitored. If the COD in treated effluent exceeds 250 mg/I, the concerned industrial units discharging such effluent shall be required to identify chemicals responsible for high COD in effluent. In case, these are found to be toxic as defined under the Manufacture, Storage and Import of Hazardous Chemicals Rules, 1989, the concerned industry shall install tertiary treatment system.

(iii) The above mentioned standards shall not be applicable to small scale detergent formulating units.

B.  Emission Standards for Incinerator

*The existing plant shall comply with norms for Dioxins and Furans as 0.1 ng TEQ/Nm3 by 1st January,2014.

Note:

(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 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 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 two seconds.

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

(vi) incineration plants shall be operated (i.e. 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 residue, as the case may be shall be re-incinerated.

(vii) The incinerator shall have a chimney of at least thirty meters height.

C. Effluent Standards for Incinerator

 Note:

(i) Effluent from scrubber(s) and floor washing shall flow through closed conduit or pipe network and be treated to comply with the effluent standards mention at 'A' above.

(ii) The built up in Total Dissolved Solids (TDS) in waste water of floor washings shall not exceed 1000 mg/1 over and above the TDS of raw water used.

D. Storm water

Note:

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

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