The Minister acknowledged the serious concerns raised by local residents and the hon. Member for Newcastle-under-Lyme. She explained that the environmental permitting system regulates waste operations, including odour management plans. The Environment Agency has issued enforcement notices and is actively working with the operator to cap the site, install gas management equipment, and conduct air quality monitoring. Public Health England is assessing health impacts according to World Health Organisation guidelines. Although the levels of hydrogen sulphide are exceptional, measures such as installing new gas extraction wells and auditing waste supply chains aim to mitigate odour emissions over the next few weeks.
