But, as to factories and business establishments whose average effluent a day is 30 m 3 and less, effluent standards such as BOD, COD belonging to items related to living environment and others are not subject to theses laws.

And the term here also means factories and business establishments with facilities that are not control subjects by the law or the ordinance, since any effluent standard is not applied to them.
