Regulation 6 Procedure for varying a permit with the permit holder’s consent
The Secretary of State may not vary a permit without the consenting authority’s consent if—
the Secretary of State intends to vary a permit in the circumstances described in regulation 5(1) (circumstances in which a permit may be varied, suspended or withdrawn with the permit holder’s consent), and
the grant of that permit required the consenting authority’s consent.
A consenting authority is to be taken to have given consent under paragraph (1) if—
the Secretary of State requests consent in writing, and
within the relevant period, the consenting authority either—
fails to give or refuse consent, or
refuses consent but fails to give written reasons for doing so.
In paragraph (2), the “relevant period” is the period of six weeks that begins with the day on which the request is made.
