Garbage collection in residential areas may start at 6 a.m. if the full City Council follows the recommendation for the early start by a council committee that heard testimony it would save the city up to $4.4 million. The savings would come with sanitation employees working 10 hours a day for four days a week instead of eight hours for five days a week. The current start of garbage collection is 7 a.m., but the Natural Resources and Culture Committee voted 4-0 on April 14 to endorse the idea and forwarded it to the City Council. The change will require City Council approval. Joan Raymond, who represents the city’s sanitation workers, said most of the workers are in favor of the change. She said it would only involve curbside collection with the city’s green and blue containers used for pick up by mechanical means. It would not involve dumpsters.
