Curated public use: Use for statutory acid-deposition targets, monitoring, and compliance design; law on the books is not ecological recovery.

Limitation: Source cards are evidence anchors, not proof that a linked claim is settled.

Source note: Defines the statutory SO2 and NOx control programme; legal design is not evidence that ecological recovery followed.
