Officials are to investigate whether more needs to be done to prevent a new incinerator project being developed in Norfolk.
The subject has returned to the political agenda in recent weeks, as part of the wider debate over devolution plans for Norfolk and Suffolk, amid fears the new structures could force unwanted developments on communities.
Members of the county council’s environment, development and transport committee supported calls for the issue to be examined when they met in Norwich on Friday.
The authority’s current policy requires the development of more environmentally friendly options for waste management than incineration.
That policy was developed after members voted to terminate the council’s contract with Cory Wheelabrator for an incinerator at Saddlebow, on the edge of Lynn, in April 2014.
County officers are now set to investigate whether further safeguards are needed to protect that policy within the devolution settlement.
Critics say the powers that would be held by an elected mayor if the plan is implemented would force through contentious schemes.
