Caerphilly County Borough Council has called for patience amid claims that planning permission for a new waste plant was ‘unlawful.’
Permission for the plant at the Nine Mile Point industrial estate in Cwmfelinfach was granted in December 2015, despite a series of protests held by residents with concerns over traffic and air pollution.
But the Lower Sirhowy Valley Residents Group has written to all Caerphilly County Borough councillors, claiming the permission granted is ‘unlawful’ because an environmental impact assessment (EIA) was not carried out.
Why is the residents’ group concerned?
Plans for the new waste treatment facility were approved by the council’s planning committee in December 2015.
Hazrem Environmental Ltd, the company behind the waste plant, has previously said up to 100,000 tonnes of waste would be processed annually at the site, including the sorting and segregating of waste for recycling and the production of fuel.
Emissions from the burning of natural gas used in an on-site drier would include nitrogen dioxide.
There is a fear that a weather phenomenon known as temperature inversion could be a risk to public health.
Temperature inversion occurs when cold air is trapped by warm air above, thus restricting any clouds, haze or pollution from escaping an area, such as the Sirhowy Valley.
Campaigners have argued that council officers should have asked Hazrem to carry out an environmental impact assessment before the decision was put to the council’s planning committee.
In not doing so, council officers rendered “any subsequent planning consent unlawful”, the Lower Sirhowy Valley Residents Group has said.
The group has received legal advice on the issue, which said failing to carry out an environmental impact assessment was “an error of law”, causing the council to breach regulations and “invalidating the grant of planning permission”.
However the development currently has lawful planning permission.
Now the council’s Plaid Cymru and Independent groups have called for clarity over the situation, while a further protest was held by campaigners in Risca on Wednesday.

Councillor Colin Mann, leader of the Plaid Cymru group, said he is “concerned that the council is refusing to look at an alternative to the judicial review process”.
“Why is there a reluctance to try to find a sensible way to resolve this flawed planning consent?” he said.
“We need answers now, not after more money has been wasted.”
Cllr Mann said that he would be writing to the council’s chief executive, Christine Harrhy, asking for answers, adding “this can’t be allowed to go on”.
Independent councillor Kevin Etheridge has also written to Welsh Government minister Julie James and First Minister Mark Drakeford, calling for a public inquiry.
Janine Reed, of The Lower Sirhowy Valley Residents Group, has called for answers.
“The council said they are waiting for their barrister but that it could take several months,” she said.
“It is our opinion that the council is stalling.”
A council spokesman said: “We want to reassure residents that this matter will be subject to full and transparent scrutiny as part of the forthcoming judicial review.
“Despite some of the claims being made in the community, it is important to note that at present the Hazrem application has lawful planning permission.
“It will be for the court to decide whether the council acted properly in granting the planning permission in 2015.
“We would urge residents to be patient and allow due process to be followed in this matter.”

February 2021 – Residents group writes to the council suggesting three ways it can overturn the decision to grant planning permission to the waste plant. Included is the suggestion the council takes itself to judicial review – which would avoid compensation having to be paid out to Hazrem should the decision be overturned.
March 2021 – Council responds to letter from residents group, saying it is seeking its own legal advice – and that the residents group may have to wait several months for a reply.
