These 4 organic solvents DMAC, NEP, NMP, DMFa are to be tested and reported as sample and report basis only for all types of discharge as there is no reporting limits set for these substances. In case if the detection is >5000 ppb in the raw wastewater/untreated wastewater then the discharged wastewater (effluent) is also to be tested and the detection is to be reported and the final conclusion will be still as sample and report only this special case is applicable only for direct type of discharge.
