Officials behind the Columbia Point construction project and its $1.5 billion price tag say they are very concerned with state plans to build an odor-control facility near their Dorchester Bay construction site, The Boston Globe said Friday.

Corcoran Jennison officials say they worry the facility, which would serve as part of a larger sewer tunnel project, would result in occasional fogs in the area that carry with them a foul stench.

Michael Lannan, the odor-control specialist for the company, alleged the possible future site would create three colored odor zones over the condominium community, as well as portions of South Boston and Dorchester.

"Inside the red, it would be like a bathroom you'd go into and want to leave," he told the Globe. "Inside the yellow, it would be like a bathroom you'd go into and probably continue to do what you needed to do, but you'd want to get out of there as soon as possible. And in the green, it would be like a bathroom."
