A series of "mega warehouses" have been reported to the health watchdog as residents living on the site's doorstep have claimed they are "developing breathing problems".
Hundreds of local residents say their lives have been blighted by five enormous warehouses that are being constructed right at the heart of their community.
Locals have campaigned for the warehouses' removal, and their movement has continued to grow, GB News understands.
The steering group, with over a thousand members, meets regularly, telling GB News they are monitoring noise pollution throughout the day and have launched an investigation into fire safety and certification of the warehouses.

At a meeting last week, more than one hundred residents gathered to hear the latest updates on their cause, vowing to keep working until their voices are heard.
Mother and respiratory nurse who lives in the local area, Theresa Davidson, said she's worried about the impact the development is having on her and her 13-year-old son, Daniel.
She told GB News: "What are we actually breathing in? That's the question I'd like to ask… I see people every single day in my workplace who have been exposed to occupational hazards, triggers, and pollutants, and I see the damage that has been caused to the lungs."
The pair suffer from asthma, and since the work began, they have both needed treatments of both antibiotics and steroids.

After a recent visit, Mrs Davidson told GB News: "We discussed what the triggers were for these problems from the last few months… we decided the pollution that is coming from this development is not helping matters at all.
"It's very, very worrying, so I would say - Please stop."
Developments at the sites have changed rapidly, with residents raising further concerns regarding noise and light pollution.
These have since been reported to the Health and Safety Executive - a Government body responsible for workplace welfare.

Only two people voted against the development of the warehouses on the planning committee

Mrs Davidson also lives next door to a local primary school, Garrett Hall.
She, along with many other residents, has concerns about how the development will impact the school's pupils.
This was just one of the driving forces behind local councillor, Stuart Gerrard, opposing the plans from the beginning.
Mr Gerrard was just one of two on the planning committee to say no, meaning the plans went ahead.
Councillor Gerrard told GB News this was without a site visit ever taking place.
He said: "There's got to be some kind of common sense when it comes to this.
"I know the Government is hellbent on putting up, planning up, building up houses and employment areas. But there's got to be that compromise on where it's going to go. This is unacceptable."
Wigan Council said the application followed all planning and consultation processes.
GB News has contacted the site's developers for comment.
