I r r r r r r r r r r- 5.Mitigation Monitoring and Reporting Program TABLE 5-1 MITIGATION MONITORING AND REPORTING PROGRAM CEMEX VERNALIS QUARRY PROJECT Mitigation Measure Responsible Monitor Timing Sign Off Party determined by the County and not to exceed one year),the Applicant shall retain a qualified acoustical consultant to evaluate outdoor activity area and interior noise levels to determine if roadway traffic associated with the project is resulting in exterior noise levels that exceed 65 dBA DNL or interior noise levels that exceed 45 dBA DNL(the exterior and interior noise level standards contained in the San Joaquin County Development Title,respectively). For interior noise measurements,residences with air-conditioning units will be evaluated with windows closed;residences with no air conditioning units will be evaluated with windows open if that is the normal operating condition. b. In those cases where interior noise levels exceed 45 dBA DNL,the Applicant will identify and implement building treatments or sound insulating features to reduce interior noise to 45 dBA DNL or less. Sound insulating features may include treatments such as installation of air-conditioning,upgrading windows and doors(including seals),and eliminating noise Flanking paths. Sound insulation would ensure that interior noise level standards contained in the San Joaquin County Development Title are met,except where affected property owners do no want sound insulation. c. The construction of 6-to 8-foot solid fences or sound walls may be feasible(especially for some residences along Haul Route 3)and may be able to substantially reduce noise from haul trucks at some of the residences along the haul route. In such cases,the mine should compensate homeowners for the fences or sound walls. However,for the residences on Segment 5(residence R9)and Segment 8 (residence R10),fences or sound walls would probably not be practical or feasible. In these locations the homes are set back a considerable distance from the road and in order to reduce traffic noise to a less-than-significant level,sound walls would need to be too massive to be practical. Residence R10 on Segment 8 is also subjected to considerable existing noise from traffic on 1-5,so any sound wall on Blewett Road would be ineffective in reducing noise from 1-5. 4.6 AIRQUALITY 4.6.1: The project applicant shall comply with SJVAPCD's Regulation VIII control measures,and shallhave an Applicant CDD and Ongoing onsite air quality monitor to ensure compliance with the SJVAPCD's Regulation VIII control measures.The monitor SJVAPCD must be familiar with the SJVAPCD Regulation VIII Fugitive PM10 Prohibitions,including implementation of all feasible control measures specified in the SJVAPCD's Guide for Assessing Air Quality Impacts. 4.6.2:While several emission-reducing measures are currently available,current proven technology limits the maximum Applicant CDD and Prior to Phase I reductions.These operational impactsare a significant impact ofthe project after mitigation.The project proposesto SJVAPCD (improvement plan approval operate new equipment,both on-site non-road equipment and haul trucks.This provides the best available operating or mining activity,whichever efficiency for the equipment.Currently,additional retrofits to reduce NOx emissions below acceptable emission standards occurs first) Cemex Vemalis Quant'Mining and Reclama5on Protect 5-5 ESA/203015 Final Environmental mpad Report June2008
