This section applies where—
the appropriate authority makes an application to the Secretary of State under section 293D, and
the Secretary of State gives a notice to the appropriate authority under section 293D(4) stating that the development to which it relates is considered by the Secretary of State to be of national importance.
The appropriate authority may make an application ("a connected application") under the planning Acts to the Secretary of State where the requirements of subsection (3) are met.
The requirements are that—
the application is—
for listed building consent under the Planning (Listed Buildings and Conservation Areas) Act 1990,
for hazardous substances consent under the Planning (Hazardous Substances) Act 1990, or
of a prescribed description,
it is considered by the person making the application to be connected to an application under section 293D,
it is neither a relevant application nor an application of the kind described in section 73(1), and
it relates to land in England.
If a connected application is made under subsection (2), but the Secretary of State considers that it is not connected with the relevant application concerned, the Secretary of State may—
refer the connected application to the local planning authority, or hazardous substances authority, to whom it could otherwise have been made, and
direct that the connected application—
is to be treated as having been made to that authority (and not to the Secretary of State under this section), and
is to be determined by that authority accordingly.
