The proposed ordinance would make it illegal to have "odors that unreasonably disturb others or interfere with their use of the transit system."
Councilman Nestor Garcia said Wednesday the proposal has some technical problems that need to be addressed.
One of those is language that would allow city police to charge a violator with criminal trespass. Garcia says only the state Legislature can pass criminal statutes.
He says testimony will be heard at the council's Transportation Committee hearing on Thursday at city hall. But he says a vote will be rescheduled for a future date.
