ISSUES OF TMDL IMPLEMENTATION IN INDONESIA• The number of provinces and districts / cities that have performed
TMDL/DTBP calculations is still small• The most difficult challenge in applying TMDL is to determine the loador quality and quantity of wastewater required in the effluent
discharge permit• Provinces and districts / cities that have calculated TMDL / DTBP havenot been able to apply the calculation results for the effluent
discharge permits

8

APPLICATION OF TMDL IN EFFLUENT DISCHARGE PERMIT• TMDL analysis is in accordance with the provisions of Article 23 of PP No.
82 of 2001: Determination of TMDL in water sources is used as a basis ineffluent discharge permit• The watersheds whose TMDLs have been established and applied, then:the load or quality and quantity of wastewater required in a effluent
discharge permit is determined in advance together with all other pollution
sources• The watershed whose TMDLs have not been established and applied, then:a. the load or quality and quantity of wastewater required in a effluent
discharge permit is determined in case by case wise (using TMDL of acertain local/segment)b. Use the national effluent discharge
