Coca-Cola plant officials have made a number of changes to its lagoon which they said say has eliminated a foul smell that had generated a number of complaints from nearby residents. The lagoon is located adjacent to the bottling facility on the South Service Road in Truesdale. Residents have complained of a sewage-like smell emanating from the property over the past few months. "We've added more aeration to the system," said Kim Glazebrook, Coke safety environmental security manager. "In the long term, we're looking at adding units that will give us more pounds of oxygen per hour. Oxygen has been really key to having a healthy system and keep it functioning. "The system is that sensitive," she added. "(There is) a critical point where oxygen is at a certain level and it can teeter on having no odor to having a strong odor - it's that fine of a line. If you add more oxygen, the system gets healthier and odor is just a sign that it could be having problems." Glazebrook said while the smell appears to be gone, Coke officials are waiting on the Department of Natural Resources (DNR) to move forward with lagoon waste removal. "We're crossing the t's and dotting the i's," she said. "We have some final pieces (to go in place)." Coke had previously sent lagoon content samples to DNR for verification and is currently waiting on another content sample analysis. "DNR approved the lab results in the past," said Glazebrook. "I haven't heard back (on the second content sample analysis), but I don't anticipate there being an issue." Upon DNR's approval of the second content sample, Columbia-based Missouri Bio-Solids will then remove the waste, she said. "We're really close to having (Missouri Bio-Solids) on site and that alleviates all smells with the system and gets it back into the normal state," Glazebrook said. Depending on the direction of the wind, the area of the smell varied, but Truesdale city officials had received complaints from businesses on East Veterans Memorial Parkway and residents on Smith Street, North Water Street, Juni Way, Boone Hollow Subdivision and Countryside Mobile Homes. The smell was also evident on Interstate 70, adjacent to the Coke plant entrance. Truesdale City Clerk Mary Lou Rainwater said no complaints have been made for a number of weeks at city hall. "We've had no complaints," she said. "In fact, I've had people come up to me and comment that they're glad the smell is gone." "We certainly do apologize to those next to the (plant) and any inconvenience and any issues this might have caused," Glazebrook said. "We're also looking at a contingency plan that would keep units on the shelf at the plant, so that way if one went down, it could be replaced immediately and we wouldn't have to slide back into this situation." She said odor neutralizers also will be kept on site. "We didn't keep odor neutralizers in supply," Glazebrook said. "In the past, we had nothing on the shelf and if we didn't have an item, we were at the mercy of getting those things ordered in here. We're definitely looking to the future and making sure we don't have a negative impact."
