Officer report

Why officers supported it

Officers considered the existing site suitable, found no significant unacceptable effects, and recommended approval subject to conditions.

“In respect of operational noise from the settlement tanks, EHS consider that the NIA has provided sufficient information to demonstrate any potential effects on residential amenity will not be detrimental, subject to condition. EHS note that noise levels during construction will exceed recommended guidance levels by 2dB at a property in Coneyville. Mitigation provided in oCEMP will assist with minimising such effects.”

“The GQRA did identify elevated concentrations of heavy metals, cyanide, and ammoniacal nitrogen in shallow groundwater, however no significant source of contamination was identified within the proposed development site boundary and therefore the elevated concentrations in groundwater were considered to be from an off-site source and/or elevated background levels and therefore site-specific remedial measures were not considered necessary.”

Officer report

What consultees said

Most consultees raised no objection or accepted the proposal subject to conditions, including controls for noise, odour, drainage, contamination and water protection.

“Consultation and Representations Consultee Responses NI Water – This is a NI Water project and as such no comment is applicable. Historic Environment Division– Historic Environment Division (Historic Monuments) has assessed the application and on the basis of the information provided is content that the proposal is satisfactory to SPPS and PPS 6 archaeological policy requirements.”

“However, it is noted that the existing access to the site is adequate and that the proposal will not lead to an increase in the number of staff or vehicles attracted to the site once the proposed development has been constructed. As such, DfI Roads has no objection to the proposal, subject to informatives. DFI Rivers – FLD 3 - DfI Rivers assessed a submitted drainage assessment and has no reason to disagree with its conclusions. NIE – NIE Networks has no objection.”
