BNG Statutory Duty

Every row is a verbatim sentence read from the named source's own page through our fetch service on the date shown, hash-pinned to the stored read (the sha of the page's visible text; the raw page is mirrored to R2).

4 of the 1 named sources that could be read published a usable figure; 1 published none and are recorded as not published, never filled in; 17 could not be read (blocked, dead or unreachable) and count nowhere.

The headline figures (median, minimum, maximum, quartiles) are over ONE figure per source in week (a source's median where its page yielded several accepted sentences), so N counts sources, never sentences; 109 candidate sentence(s) were refused by a reviewer with the reason recorded.

The fuller derivation this dataset is chartered to grow into (not yet what the figures above are; they are each source's own published figure as read): one row per rule with its source and date: the 10% gain condition (Environment Act 2021 Schedule 7A, inserted into the Town and Country Planning Act 1990), the exemptions (de minimis, householder, self-build, biodiversity gain sites), when the small sites metric may be used and by whom, what the biodiversity gain plan must contain, and the authorities' own monitoring fees where published; the joined table of rule, threshold and who may sign it off is what no single government page lays out.

109 candidate sentences on these pages were refused by a reviewer; each refusal and its reason is recorded in the review ledger.
