NAUGATUCK — The Board of Mayor and Burgesses continued a hearing on amendments to the litter ordinance to its September meeting. Officials are proposing several changes to the ordinance. Among the changes is a new section to govern collection boxes — bins that are used to collect donations of items like clothing. The proposed new section requires the owner of a bin to register it at Town Hall. The area around the bins has to be kept clean, the proposal states, and any items left outside bins have to be removed within five business days.
