I am not aware of any proposed regulations put forward by the planning regulator, as referred to in the question. Further, a thorough check in my Department indicates that correspondence of this nature has not been received from the Office of the Planning Regulator (OPR).
On a point of information, I wish to clarify that only the Minister has the power to make Regulations; the making of Regulations is not a function of the Office of the Planning Regulator. Moreover, whereas the Minister is responsible for determining planning policy, the statutory role of the planning regulator is plan evaluation and assessment; oversight and review of the performance of planning functions and the delivery of planning services; and, research, education and training.
