Regulatory context

Partial review. This is not an exhaustive review of applicable law.

China: GB 18918-2002 and the 2025 amendment

Partial documentary review; human legal review pending. MEE announcement 2025 No. 24 modifies GB 18918-2002 and states application from 2026-03-01; it is not a renumbered standard. The annex provides a transition from 2028-01-01 for construction cohorts defined in its tables, which is neither brought forward to 2026 nor generalized to all plants. Territorial scope, effluent destination, classes and permit require review; a HydroWASTE label does not assign a legal class.

Confirm the scope of GB 18918, provincial rules and the individual permit.
Distinguish instantaneous values from averages; verify sampling point and the standard version applicable to the date.
Do not assess a historical inventory against 2026 limits without measurements from the relevant period.
Separate application from 2026-03-01 from the 2028 transition for specific cohorts; no dates, values or rules are assigned here to a facility.
