Peraturan Menteri Lingkungan Hidup dan Kehutanan 21/2018 (Peraturan Menteri Lingkungan Hidup dan Kehutanan Nomor P.21/MENLHK/SETJEN/KUM.1/7/2018 tentang Perubahan atas Peraturan Menteri Lingkungan Hidup Nomor 5 Tahun 2014 tentang Baku Mutu Air Limbah) is an Indonesian ministerial regulation that amended the national wastewater quality standards by replacing the effluent standard for the leather tanning industry. It was signed by the Minister of Environment and Forestry on 13 July 2018 and took effect on its promulgation on 19 July 2018.[1]

The regulation is the first of two amendments to Permen LH 5/2014, the base instrument of the effluent-standards layer described at wastewater and sanitation regulation in Indonesia. It changes a single annex and no article of the parent regulation.[2]

Background

The preamble gives two grounds. The first is the Minister's power under Pasal 20 ayat (2) huruf b of Undang-Undang 32/2009 on environmental protection and management to regulate wastewater quality standards. The second is that the tannery standard in the 2014 regulation did not fit conditions in the field and therefore needed to be changed.[3] Its legal bases also include Government Regulation 82/2001 on water quality management and water pollution control and Presidential Regulation 16/2015 on the Ministry of Environment and Forestry.[3:1]

Under the 2014 regulation, the leather tanning industry is one of forty-six categories of activity with a sector-specific standard, set out in Lampiran II.[4]

Provisions

The regulation has two articles. Pasal I replaces Lampiran II of the 2014 regulation with the annex attached to the amendment, and Pasal II provides that the amendment takes effect on the date of promulgation.[2:1]

The replacement annex sets maximum concentrations for ten parameters for tanneries: a pH range of 6 to 9; 30 mg/L biochemical oxygen demand; 200 mg/L chemical oxygen demand; 2 mg/L ammonia as nitrogen; 30 mg/L total Kjeldahl nitrogen, defined as organic nitrogen plus total ammonia; 0.6 mg/L total chromium; 5 mg/L oil and grease; 0.8 mg/L sulphide; and 60 mg/L total suspended solids. It also caps the volume of wastewater at 40 cubic metres per tonne of raw material.[5]

Relationship to other instruments

The second amendment to the 2014 regulation, Permen LHK 16/2019, recites the parent regulation as amended by this instrument, confirming its place in the amendment chain.[6] That second amendment dealt with the textile standard, which was later revoked together with its transition clause by Permen LH 12/2025; the tannery annex introduced in 2018 was not affected by the 2025 textile regulation.[7]

CRPG's regulatory tracker published an analysis of the amendment on 26 November 2025.[8]
