conditions;

The committee observed that trial run hadalready been carried out for utilization ofsimilar hazardous waste in case of the Eightunits located in Morbi area of Gujarat.However, scrubber was installed in all thoseunits whereas no such APCDs have beeninstalled in these 10 units.

In view of above, the committeerecommended to carry out trial run inpresence of CPCB & GPCB officials in anytwo units, one out of which with scrubber andthe other without scrubber for performanceevaluation with and without scrubber.

In case, the above trial run reportdemonstrate compliance with stipulatedstandards (other than NOx, if applicable) inunit without scrubber, installation of scrubbermay not be required. However, if it compliesonly in unit having scrubber, all the otherunits shall be asked to install scrubber.Permission may accordingly be given forutilization of tarry residue in furnace for aperiod of one year with the following

I GPCB may review NOx standard for thiskind of material.

Tarry residue to be injected into furnaceonly after the furnace achieves morethan 1400°C by using conventional fuels(FO/ LDO/ PNG/ CNG etc.)

Only electrical heaters should be usedfor heating the tar for liquefaction.

iv. Fumes if any released during heatingshould be channelized as combustion airto furnace.

In case, the trial run demonstrates non-compliance in both the units, the report shallbe discussed in the next committee meeting.

Protocol for cleaning of contaminated drums/containers/ barrels for re-use and manufacturing ofplastic granules:

The drums containing solid material may be taken into cleaning process and in case of liquids, only selected list of chemicalscontaining drums may only be permitted. Such list to be prepared by CPCB in consultation with generating industry and SPCB.

The unit shall provide details on type of industries from where contaminated drums/ container shall be procured alongwith thedetails on the content of the material stored.

The units involved in cleaning of contaminated drums/containers/barrels should have the following minimum requirements;

A. Handling and Storage

Separate covered storage area for both contaminated containers and cleaned containers. There should be proper slopeand spillage collection pit.

The manifest system and logbook should be maintained. Labeling should be done on all contaminated drums indicatingsource and date of receipt and type of drum

3. Prior to cleaning, the left-over or residual material in the drums should be transferred into a separate container for safestorage and disposal at TSDF.

B. Cleaning Procedure

All the drums should be cleaned with hot caustic solution up to 2% concentration or detergent.

There should be two stage cleaning i.e. caustic /surfactants (detergent) cleaning followed by fresh water cleaning.

Provide parapet wall along the container storage and washing area.

The number of nozzles in 1 HP pump shall not exceed 3.

The nozzles should be modified with multiple jets to ensure that water jets hit whole inner surface of the containers.

There should be separate area with provision of hose pipe with spray nozzle for washing outer surface of the containers.

C. Effluent Treatment

Flow through evaporator should be regulated based on heating capacity of the evaporator. Water flow meter should beinstalled at the inlet to evaporator and at the inlet to ETP.

The vent of vacuum pump should be elevated at least up to 2 mtr above the roof level

The units should ensure zero discharge by evaporation of the effluent.

Incase of availability of CETP, the units shall become members of the same and send their effluent for final treatment anddisposal

D. Labeling of Cleaned drums for re-use

The labels on the washed containers for re-use should be removed (preferable with a paint) and the cleaned containersshould be labeled with prominent indelible text

"Drum Cleaned by : M/s • Date:

"For industrial use only

NOT for storing any food material"

The above is not applicable in case the cleaned drums are shredded and re-cycled.
