I want to know whether Factories Act, 1948 and Boilers Act, 1923 applicable for operating Sewage Treatment Plants of 74 MLD and 56 MLD, respectively.

What are the legal compliance/ approvals needed other than Consent to Establish (CTE), Consent to Operate (CTO) from Pollution Control Board, PESO License for storing more than 5 tonners of chlorine at a time, fire approval, electricity permission etc?
