PA-0800005 Page 2 30703 S. MacArthur Drive, Tracy The EHD has concerns that the facility operating at full capacity would not be able to safely handle the waste. a. Vehicle traffic: the project description indicates that the facility is proposing to increase vehicle traffic from 560 vehicle trips to 1727 vehicle trips per day. The site is confined and the tipping area is small. 1. Provide calculations that show the number of vehicles that can safely unload at each of the tipping areas onsite. 2. Provide information showing traffic patterns. 3. Provide anticipated vehicle quelling time through the scales and tipping area. b. The proposed project description mentions that the additional hours of operation will allow the facility to handle additional vehicles. This is true to a point. Vehicles that arrive at the facility are not evenly spaced and tend to show up at approximately the same time. 1. Indicate the area designated for vehicle quelling and explain how the area will accommodate the expected vehicle traffic. 2. Discuss the anticipated number of vehicles per hour. F. Tonnage: the project description proposes to increase the per day tonnage by 2.5 times the current tonnage. The design calculation does not discuss the amount of equipment that would be on the tipping floor in order to facilitate the processing of the waste. The project description does not mention how much area would be required for vehicle unloading (type of vehicle, size, volume of waste contained), or the number of vehicles that would be unloading at one time. The proposed project does not indicated if there will be a separate unloading area for the self haul customers or the number of waste screeners/spotters on the tipping floor during the operation. 1. Provide a facility capacity study that analyzes the traffic and waste volume as it relates to the proposed changes and facility capacity. Include the calculations that will take in to account the space or area required to safely conduct the proposed operations. G. The project description on page 22 indicates that the facility does not knowingly receive Household Hazardous Waste (HHW). The facility currently collects antifreeze, waste oil, batteries, and paint. Revise to accurately reflect current site conditions. H. The project description on page 28 indicates that if prohibited wastes are identified, the hauler is required to remove the waste from the facility for proper disposal elsewhere. When a hazardous waste is identified, it is at that point it must be handled as a hazardous waste. The hauler cannot remove the waste from the site unless it is a hazardous waste hauler. Provide additional information clarifying the procedure in detail. I. The project description on page 18 of Report of Compost Site Information (RCSI) makes reference to a CEQA analysis done in 1999 and references a Solid Waste Facility Permit (SWFP). According to the Environmental Health Department (EHD) records there was no SWFP issued for this facility in 1999. Provide clarification regarding this statement. J. The project description on page 23 of the RCSI indicates that the facility plans to use a CTI system composting operation as part of the expansion. This type of operation requires the use of blowers to aerate the compost. Provide design information and calculations for the CTI system.
