Ottawa residents will likely have to tag every garbage bag or bin they set out at the curb starting next spring. This is the city's latest move aimed at reducing garbage headed to the landfill. The City of Ottawa has been concerned that its landfill on Trail Road could be full within 13 to 15 years. It hopes the plan — put forward Thursday at a technical briefing — can buy them two more years. Residents are encouraged to sort more waste into blue and black recycling bins. As proposed, households would get 55 garbage tags each year and could buy extras for $3 each. Right now, households can set out up to six garbage containers, even if most never do. For trash containers, the limit is 15 kilograms. No loose garbage will be permitted inside. "It's not meant to be punitive, but rather to encourage residents to rethink their disposal habits," said Nichole Hoover-Bienasz, program manager for long-term planning with the solid waste services department. The curbside waste policy will come before the environment and climate change committee on June 5 and the full city council on June 14. It's part of the much larger master plan for dealing with solid waste that staff are preparing to bring to council this fall. That plan will tackle larger questions such as whether the city needs a new landfill. This could cost up to $450 million and take 15 years to operate. Given that "pay as you throw" programs are common in other communities, including nearby Carleton Place and Almonte, city staff had many municipalities consult in shaping Ottawa's plan. The city does not plan to penalize residents unless there are repeat issues and will focus instead on educating residents to change their behavior. Staff also acknowledged there could be an increase in illegal dumping during the first few months of the proposed policy. Coun. George Darouze, who represents the rural Osgoode ward, worries about preventing that. "From what I'm seeing right now, I'm not confident that we'll have enough enforcement," Darouze said, adding that he's seen issues in Ottawa's surrounding smaller communities. The plan includes hiring two full-time inspectors, followed by another two during the first year when they expect illegal dumping. The Ontario government aims to ban all food and organic waste from landfills by the end of the decade. It wants municipalities to collect 70 percent of food and organic waste in curbside green bins by the end of the year. Changing that behavior could be a big task, with Lindsay Webley, project manager of environmental programs, noting that 82 percent of all waste comes from the curb. "This is equivalent to each household throwing out a grand piano's worth of garbage for the year," Webley said. The city has found that about 58 percent of trash cans could be diverted to blue, green, or black bins. Thursday was garbage day in Hintonburg, and several residents shared their thoughts with CBC about the proposed changes. Kyle Gervais said he hopes city staff will consider what worked and what didn't in other jurisdictions. "I'm glad they're creating a model for people to pay for extra services if they need them," he said. According to a staff presentation, nearly three-quarters of residents already set out two items or less every two weeks. Duncan Bury of Waste Watch Ottawa said the proposed changes have been a long time coming and Ottawa is playing catch-up. While Ottawa may be one of the last major Canadian municipalities to introduce such a program, Hoover-Bienasz said the city has brought in several other major changes, including the green bin in 2011 and bi-weekly garbage collection in 2012. Some changes were met with resistance, she said, including because of the "yuck factor" associated with using a green bin. "We've been gentle, I'd say, nudging residents in the last few years to make it easier to participate," Hoover-Bienasz emphasized.
