Multiway stop controlled intersection analysis is the only exception to the use of PCE's in this analysis. For these intersections, the analysis was completed; with unadjusted traffic volumes. A review of the results indicated that the total approach volumes under the worst case scenario were approximately 60 percent of the level of service (LOS) C volume. In other words, calculating PCE's was not necessary in order to determine that the multiway stop controlled intersections would continue to operate at or above LOS C. B 21 The projected trips for the Tracy MRTF include trips diverted from the closure of the Corral Hollow Landfill B 22 According to the County of San Joaquin Department of Public Works, accident classifications are mutually exclusive. The County's classification system assumes that reported accidents involve property damage. However, if an accident also involves injuries, then it is classified as an injury accident. This clarification results in the changes to the safety conditions' discussed in the setting and in the impacts and mitigation sections contained in Chapter 4.3, Traffic/Circulation. B 23 Chapter 4.3, entitled Traffic/Circulation, has been revised to include this information. B 24 Project related truck trips on this at -grade railroad crossing would not result in a significant impact. The Project P 9 9 9 P significance criteria in the EIR defines a significant impact for roadway structural condition as an increase greater than 1.0 between no project and project scenarios. The traffic index on this section of roadway increases from 11.58 to 11.67 (a difference of 0.09) as a result of 2010 project related traffic. Since the TI is measured in units not less than 0.5, the structural section of roadway at this location would be designed for a TI of 11.5 with or without the project. B 25 The comment has been noted. The water use resulting from conventional agricultural production is variable and dependent upon soil conditions and the type of crop to be grown. There is no current water use at the site, as the site is fallow and used for grazing at this time. Previous water 'usage" at the site was that ;quantity of water used to process the aggregate mined from this pit. However, that water was pumped from a well on a contiguous parcel and used at the processing plant on that parcel. Water usage in aggregate processing can range from 100 to 12,000 gallons per minute depending upon the quantity of material processed and the efficiency of the equipment. Anticipated water use for the Tracy Materials Recovery and Transfer Facility is as cited elsewhere in the Draft EIR. B 26 The comment has been noted. B 27 The comment has been noted. There are two ponds proposed at the site. One is a retention pond for runoff from all areas except the wood storage and yard waste composting area, and the other is a lined evaporation pond to collect runoff from the wood storage and yard waste composting area.
