Present:
Now, the industry has applied for obtaining renewal of consent to operate under the provision of the Water (Prevention & Control of Pollution) Act, 1974 and the Air (Prevention & Control of Pollution) Act, 1981 for manufacturing of 8"Silicon Wafers @ 12000 No./Year and 6"Silicon Wafers @ 900 No./Year, alongwith requisite documents.
Fee Details:
The industry has deposited Rs. 1440000/- vide UTR No. RBISN62026022581535877 dated 25.02.2026 under Water (Prevention & Control of Pollution) Act, 1974 and Rs. 1440000/- vide UTR No. RBISN62026022581535912 dated 25.02.2026 under Air (Prevention & Control of Pollution) Act, 1981. The fee deposited by the industry is adequate upto 16.01.2028 after adjusting late fee/ penalty as well as NOC regularization fee against the total cost of the project Rs. 1381.16 crores as per latest CA certificate submitted by the industry.
The industry has submitted point wise reply to the observations for which its earlier application was returned and the same is reproduced below:
Sr. No. Observation Reply by industry
1. Earlier, the project proponent has submitted CA certificate with the value of fixed assets of Rs. 1287.99 crore. Now, the project proponent has submitted CA certificate of capacity 1381.11 crore. The project proponent is therefore required to submit justification/explanation for the increase in the reported value of fixed assets. The rise in value (~93.12 crore) of fixed assets accounts for the un-depreciated value of the fixed assets which includes furniture items, Renovation works, Repairs of the fixed assets etc. It does not include addition of any plant and machinery relating to processing/ manufacturing activities.
2. The project proponent has not submitted the NOC regularization fee. Also, as the increased value of fixed assets, mainly due to Buildings / furniture etc., is well within the Fee slab (Rs. 1000 to 2000 crore) for the lumpsum payable charges, the NOC regularization fee shall not be applicable in this case. Please consider.
3. The project proponent has not linked consent fee with the application. For online linking of fee with application, RBI option was not available in the enlisted banks on the portal. Also for offline linking of UTR no. of fee, the system was not picking UTR nos. starting with “RB”.
It is requested that UTR no. RBISN62026022581535877 dtd. 25.02.26 for Rs. 14.4 lakhs for CTO for 2 years under Water (Prevention & Control of Pollution) Act, 1971 may be linked with application no. 31501813 dtd. 18.03.2026.
The industry has submitted compliance report of the conditions of the earlier granted consent to operate under the provisions of the Water (Prevention & Control of Pollution) Act, 1974 and the Air (Prevention & Control of Pollution) Act, 1981.
Visit:
The site of the industry was visited by the undersigned on 17.04.2026. During the visit, it was observed as under:
1. The unit has installed fabrication laboratory for the manufacturing of 8” and 6” silicon wafers.
2. The wastewater generated from wet etching, RO Reject and regeneration of Ion exchange resin mix bed is treated in the Effluent Treatment Plant.
3. The industry has also installed water treatment plant for carrying out treatment and sterilization of the raw water.
4. The industry has installed Effluent Treatment Plant comprising of toxic tank, equalization tank, neutralization tank, clarifier, pH adjustment tank, holding tank. The wastewater generated from the fabrication laboratory is collected in an equalization tank, where the wastewater (RO reject and DM plant regeneration) from the RO plant followed by DI plant also gets mixed. The wastewater is then homogenized in the said tank and pumped to the neutralization tank, where the lime dosing and poly electrolyte dosing is carried out and thereafter the wastewater is sent to clarifier, where pH of the treated wastewater is adjusted at the outlet of clarifier, if required.
5. The industry is using treated wastewater after ETP onto land for plantation in an area of 18 acres and remaining water is disposed off into MC sewer. The industry is marinating record of operation of ETP and quantity of treated wastewater use for plantation and disposed off into MC sewer. The effluent samples were collected from the outlet of ETP and sent to Head Office laboratory for analysis. Results of the same are awaited.
6. The industry has installed the wet scrubbers as APCD with the MOCVD (Metal Oxide Chemical Vapour Deposition) reactor and the same is provided with stack of adequate height.
7. The industry has also provided 2 no. process sheds & emissions are generated from the process area due to the use of HF, NH3, H2SO4, Acetic acid etc for etching and other purposes. The industry has provided packed bed wet scrubber followed with stack of adequate height with individual process areas. The stack emission samples were collected and sent to Head Office laboratory for analysis. Results of the same are awaited.
8. The industry has installed 7 no. of DG sets (2 DG set capacity of 1250 KVA, 3 DG set capacity of 1650 KVA ,1 DG set Capacity of 625 KVA and 1 DG set capacity of 500 KVA) which are placed in an enclosed room and stacks of the adequate heights. The representative informed that in the application form they have mentioned Dg set as 5010 KVA in place of 3 x 1650 KVA and 2500 KVA in place 1250 x 2.
Recommendations:
In view of the above, it is recommended that the consent to operate under the provision of the Water (Prevention & Control of Pollution) Act, 1974 and the Air (Prevention & Control of Pollution) Act, 1981 may be renewed upto 31.12.2027 to the project proponent, subject to suitable conditions and special conditions as mentioned in the original consents, please.
