CONCLUSION <br />From the analysis summarized herein, it appears that increasing <br />~ coal production to 1,3-million TPY at CIdI 's Orchard Valley Mine will not <br />have a significant adverse effect on traffic service on SH 133. A total <br />peak-hour traffic volume was conservatively estimated for the year 1982 <br />assuming a 1.3-million TPY production level. The estimated traffic volume <br />' is considerably less than the volume permissible at level of service C*, <br />~ generally considered desirable on rural highways such as SH 133. <br />I <br />A review of truck operation, maintenance and qualification standards <br />~. for truck drivers indicated the present truck operation to be a very safe <br />one. Increased production of coal should have little effect on the safety. <br />. There appears to be no need for such design modifications as runaway truck <br />ramps. <br />~ Conservative noise model predictions indicate that increasec production <br />~- will result in only a slight (3 to 4 d6) increase in Ldn noise levels in <br />~` adjacent areas. At no residence will the 65 dBA standard adopted by many <br />L <br />agencies (such as the FHWA, HUD and FAA) be exceeded. It was noted, however, <br />E- <br />~ that efforts should be made by truck drivers to minimize noise emmisions <br />during evening hours. <br />L <br />The analysis of air quality indicated that the increased CWI traffic <br />at 1.3-million TPY will have a negligible impact. <br />* Level of service C is a measure of traffic service defined by the <br />1965 Highway Capacity Manual. <br />-3- <br />
