19 After Part 7 (appeals) insert—

“PART 7A Biodiversity Gain Plan

37A Meaning of biodiversity gain hierarchy
In this Part, “biodiversity gain hierarchy” means the following actions in the following order of priority—
(a) in relation to onsite habitat with a habitat distinctiveness score, applied in the biodiversity metric, equal to or higher than four—
(i) avoiding adverse effects of the development, or
(ii) insofar as those adverse effects cannot be avoided, mitigating those effects;
(b) in relation to any onsite habitat which is adversely affected by the development, compensating for that adverse effect by—
(i) habitat enhancement of onsite habitat;
The term “habitat enhancement” has the meaning given by paragraph 12(2) of Schedule 7A to the Town and Country Planning Act 1990.
(ii) insofar as there cannot be that enhancement, creation of onsite habitat;
(iii) insofar as there cannot be that creation, the availability of registered offsite biodiversity gain for allocation to the development;
(iv) insofar as registered offsite biodiversity gain cannot be allocated to the development, the purchase of biodiversity credits.

37B Form and timing of submission
A biodiversity gain plan submitted to a planning authority must be submitted—
(a) in writing;
(b) no earlier than the day after the day on which formal notification is given of the decision to grant planning permission.
