Planning Commission Meeting Minutes February 12, 2015 Page 10 of 12 McCartney says if the trail is located there, the fence will be relocated. Applicant Presentation: Dmitri Tepo, City of Louisville, Water Resources Engineer Currently Howard Berry WWTP discharges all the water treatment plant byproducts to the sewer and subsequently to the wastewater treatment plant. It is causing the WWTP to violate its discharge permit. Howard Berry WWPT is being put on a compliance schedule which is mandating the plant to significantly reduce its discharge to the wastewater plant by August 2015. This project is designed to do this. We will no longer be discharging to the sewer but will be drying the residuals on site and then landfilling them. Commission Questions of Applicant: Tengler asks if Howard Berry is a collection unit for all the wastewater before it goes to the wastewater facility in east Louisville. Tepo says that Howard Berry is one of the two drinking water facilities that the City operates. The reason all water treatment plants generate residuals is because as water is cleaned, the result is residual. It is typical of municipalities in this area. Wastewater treatment standards are getting tighter and in the past, it did not matter that all the plants were sending down residuals. With the tighter standards, it is more difficult for the plants to meet their discharge permits because of the extra load they are receiving. Tengler asks about the process of taking the dry bed material to the landfill. Tepo says there are five separate drying beds or cells. Each cell will be filled and will dry and de -water by evaporation and infiltration. The byproducts are placed on top of a sand bed so the bed will not remain slushy or liquid for a long time. After byprrt has dried, a bobcat is used to load a dump truck and haul it to a landfill. Tengler asks how toxic is it? No special disp ®sal? Tepo says it is not. They have to meet toxici` ..dioac tandards. According to their testing, it can be delivered to any landfill. Brauneis asks if it is primarily minerals and me - ? Tepo says yes. Mainly, the concern at landfills i dionuclides and metals. Tengler asks if the neighbors have to w. bout? Tepo says there is no smell or odor. Tengler asks about the current fencing of 3 st? barb wire. He asks if the facility is under video surveillance? Tepo says fencing details have not been discussed. He assumes the 3 strand barb wire is typical for water and wastewater facilities. It is not currently under video surveillance. They hope to run fiber optic cable to it and get surveillance. Pritchard asks about solar panels that were approved to go on the west. Tepo says yes, they will be on the west. Public Comment: None. Summary and request by Staff and Applicant: Staff recommends approval with condition stated. Russ states the purpose of this is accounting for clarification. As the trail comes forward, Staff is asking this facility to do what any application would do regarding planned bicycle improvement. This will give the City Manager, Public Works Director, and Finance Director the nexus to say a portion of the trail can come from the Water Enterprise Fund because it is the cost of the Fund to do business in Louisville. We can pull a portion of the funding from the water fund itself. It needs to meet the 12% requirement. Closed Public Hearing and discussion by Commission:
