Residents who complained about noise from a recycling firm given a temporary licence to operate on Sundays say they were unable to get help because the authorities did not work at weekends.
Hamilton Waste and Recycling, which last year became Scotland's first carbon neutral waste centre, is now applying for permission to make their seven day a week operation permanent after running Sunday operations for the last year.
However a report to East Lothian Council's planning committee says objectors had claimed that when they tried to complain about issues during the Sunday operation they could not get a response.
