The industry was visited by EE & AEE of this office on 14.06.2024. During visit, it was observed as under:
1. The industry is engaged in the business of manufacturing of API and its intermediate product and same was in operation at the time of visit.
2. The storm water line and the adjoining drain were checked and no presence of industrial/ yellowing effluent was observed during the visit.
3. The manufacturing record of the industry was checked and as per the record the manufacturing has been within the consented capacity.
4. The industry has now cleared the legacy effluent and further the industry has got lifted entire legacy sludge from the lagoons i.e. about 1200 tons sludge to TSDF Nimbua since last year.
5. Half of the lagoon has been land filled and the industry is developing green area over the same. In the other half 8 small collection tanks have been provided and the industry is providing shed on the same. The wet scrubber to be provided on these collection tanks has been installed and the same shall be commissioned within 15 days.
6. The industry has now installed new MEE of capacity 80 KLD and ATFD in compliance to the consent conditions and the same was in operation during the visit.
7. The industry has also provided pre-treatment ETP before the MEE, so as to remove the TSS content from the effluent before feeding the same into MEE.
8. The industry has provided separate STP for treatment of domestic effluent and the same was in operation during the visit. The treated domestic effluent is being used for irrigation of green area within the project.

11. The industry has installed 03 DG sets of capacity of 500 KVA each, which are equipped with canopy and adequate stack height.
As above, it has been observed that the industry has now complying with the conditions of previous consents granted to it. It has cleared the entire legacy effluent and the entire legacy sludge @ 1200 Tons has been lifted to TSDF Nimbua. Further, the lagoon has been filled and now covered collection tank have been provided with alkali scrubber as APCD, so as to address the odour of the industry.
The industry has been visited on 28.08.2023, 27.12.2023, 21.03.2024 & 14.06.2024 since the disconnection of the industry and no effluent was observed in the nearby drain. Further, each times the industry has made significant improvement and has now also removed the legacy effluent and with the addition of 80 KLD MEE, the industry now has adequate MEE capacity to treat the effluent generated from the process.
In view of above, it is recommended that:
a) Directions may be issued to PSPCL authorities for permanently restoring the electric connection of the industry.
