The Scottish Ministers may vary a consent under section 36 or 37 if—
they consider that the consent ought to be varied—
because of a change in circumstances relating to the environment, or
because of technological changes, and
the person for the time being entitled to the benefit of the consent agrees to the variation.
The Secretary of State or the Scottish Ministers may by regulations make provision about variation under this section, including in particular provision about—
the procedure for getting agreement;
publicity, notification and consultation requirements;
rights to make representations.
The regulations may provide for any statutory provision applicable to the grant by the Scottish Ministers of a consent under section 36 or 37 to apply with specified modifications to the variation of such a consent under this section.
In this section, "statutory provision" has the same meaning as in section 37A.
