5.12 TRAFFIC AND TRANSPORTATION 5.12.2.2.4 Intersection LOS with Construction Traffic The peak hour traffic generated during the construction period was added to the existing turning movement counts on the analyzed intersections within the study corridor. The results of the existing and"with project" peak-hour LOS analysis for all study area intersections are summarized in Table 5.12-7. As shown in the table, all study area intersections will continue to operate at an acceptable LOS. The addition of construction traffic will not cause significant impacts on traffic operations at intersections. 5.12.2.3 Heavy Haul Routes The LEC proposes to use the heavy haul routes shown in Figure 5.12-4. Route 1 would require the construction of a new temporary access road (approximately 100 feet long) connecting the on-ramp to the southbound lands of I-5 from eastbound SR 12. The temporary access road would require an encroachment permit from Caltrans. 5.12.2.4 Transport of Hazardous Materials Hazardous materials that will be onsite during construction are usually small in quantities relative to the quantities used during operation, and will include petroleum products such as diesel and oils,citric acid, sodium carbonate,and sodium nitrite. The hazardous substances that will be used by the project during operations are: anhydrous ammonia, sulfuric acid,cleaning chemicals,trash pickup,lubricating oil,lubricating oil filters,laboratory analysis waste,oily rags, oil absorbents,water treatment chemicals, sodium hypochlorite, diesel,welding gases and lab chemicals. The average delivery frequency is estimated to be twelve per week. These materials would be transported as hazardous materials or hazardous waste. Transport route arrangements would be required with Caltrans officials for permitting and escort, as applicable. Because the transport of hazardous wastes will be conducted in accordance with the relevant transportation regulations,no significant impact is expected. According to Division 13 Section 31303 of the CVC,the transportation of regulated substances and hazardous materials will be on the state or interstate highways that offer the shortest overall transit time possible. Transporters of hazardous or explosive materials must contact the California Highway Patrol (CHP) and apply for a Hazardous Material Transportation License. Upon receiving this license,the shipper will obtain a handbook that will specify the routes approved to ship inhalation hazardous or explosive materials. The exact route of the inhalation or explosive material shipment will not be determined until the shipper contacts the CHP and applies for a license. Transportation impacts related to hazardous materials associated with the project operations will not be significant since deliveries of hazardous materials will be limited. Delivery of these materials will occur over prearranged routes and will be in compliance with all LORS governing the safe transportation of hazardous materials. 5.12-18 SAC/371322/082380003(LEC_5.12_TRAFFIC_AND_TRANSPORTATION.DOC)
