IMPLEMENTASI BAKU MUTU AIR LIMBAH BERBASIS DAYA TAMPUNG BEBAN PENCEMARAN BADAN AIR PENERIMA PADA KEGIATAN PERTAMBANGAN BATUBARA
Abstrak: This research is
based on the fact that many rivers in East Kalimantan are complained to be
polluted by coal mining activities even though many rules to protect surface
waters are in place and obeyed. To explain why it is happened, an audit is
conducted to the regulations and to the implementation of the regulations. Desk
audit is carried out to assess whether the regulations about waste assimilative
capacity and effluent limitation that are currently endorsed are appropriate or
not compared to the TMDL concept. The audit of implementation is carried out to
assess whether the regulations are applied thoroughly or not. The results is
that the technical regulations to determine the class of water and to
allocation waste load are absent.
Therefore, many regulations related the water quality based effluent
limitation are not implemented properly. Most of effluent limitation refer
directly to the national or provincial standards that are usually less
stringent than the water quality based standard of the local rivers or small
rivers. The case study in Loa Haur River obtains that the waste assimilative
capacity of the river is 33.696 ton of TSS/day. The WAC that is allocated to 6
(six) coal mining in the sub basin of Loa Haur is 5 ton/day. The allocation is
based on their production capacity. The results of water quality based effluent
limitation of coal mining companies in the Loa Haur sub basin is 0.17 ton
TSS/day or its concentration of 114.63 mg/L.
