Landfill, therefore, 185 one-way vehicle trips were estimated. The total combined vehicle count was estimated to be 620 one-way vehicle trips per day(ref: EIR pg 60). To establish baseline conditions, traffic counts were performed at three study intersections in August 2001 and at the project driveway in July 2002 (ref: EIR pg 78). The EIR Consultant also used June 2002 data from the Forward Landfill scales (ref: EIR pg 86). All vehicles crossing the scale at the Forward Landfill are recorded and counted toward the daily vehicle lit. Both the traffic counts and the recorded vehicle data do not distinguish between vehicles carrying refuse and those carrying ADC, soil or other material. Because Forward is planning to continue to count both refuse and ADC/soil vehicles andr is not requesting that only refuse vehicles be counted toward the daily vehicle limit, the planned use is consistent analvsls -� A cumulative traffic impacts analysis was performed to identify long term impacts of the project. This analysis was based on a landfill closure date of 2020 (ref. EIR pg. 95)wtu_ 'ch ams discussed in the Closure Date section, is based on a refuse tonnage rather than a total tonnage. AIR QUALITY/ODORS Air emissions for items such as reactive organic compounds(ROC) and ROGs were based on estimated landfill gas production rates. The analyses were performed for a"worst-case refuse disposal rate" of 3 million tons per year4(ref. EIR pg. 119). The analyses, therefore, assumed that the tonnage limit in the Project Description is a refuse tonnage limit. It is worth noting that the 3 million tons per year disposal rate used in the analysis not only covers the amount of refuse that could potentially be delivered to the facility, but would also more than adequately cover all materials including ADC and soil cover. PUBLIC HEALTH AND SAFETY The Human Health Risk Assessment for Forward/Austin Road Landfill Expansion was prepared by Environ (2002). This risk assessment formed the basis of the human health risk analysis in the EIR. As stated on page 2-2 of the Environ report(see Attachment D),the risk assessment was based on 6,680 tons per day of refuse from the former Forward Landfill and 1,200 tons per day of refuse from the former Austin Road Landfill. In addition to the refuse tonnage assumption,the EIR analysis of risk assessment discusses the closure date of 2020(ref: EIR p . 18). The risks are assumed to be reduced for the propose project versus the baseline conditions because waste will be moved over a shorter period of time. As discussed in the Closure Date section above, if the tonnage limit was a total tonnage limit rather than a refuse tonnage limit, the estimated closure date of the landfill would extend beyond 2020 and the analysis would not be consistent with the EIR assumptions. C', Based on the information presented above, the EIR Project Description and supporting analyses were based on the tonnage limit being a refuse tonnage and not a total tonnage.
