Depending on how the city council views three recent presentations, there may be some changes in the method and frequency of Rockdale’s trash collection. Doravion Dickens (foreground) and Carlos Lohiengel of Waste Management make their rounds in east Rockdale as part of the customary twice-weekly collection. The council met in workshop session Tuesday to study contract offers, all of which would involve a “slight” increase in collection rates. Waste Management, IESI and Texas Disposal have made bids. The city will discuss trash collection during a meeting set for 5:30 p.m. Monday at City Hall. See editorial, page 5A.
