Agency for Monitoring and Reporting Action Indicating Impact Mitigation Measure/Condition Type of Review Compliance Compliance or Review Verification of Compliance or Annual Review of Conditions Monitoring Reporting By Date Remarks III. Air Quality During Construction : a) Emissions of fugitive dust from any X Air Pollution Control District Construction Permit active operation, open storage pile, ordisturbed surface area, shall be controlled so that dust does not remain visible in the atmosphere beyond the boundary line of the emission source. b ) When wind speeds result in dust emissions crossing property lines, and despite the application of dust control measures, grading and earthmoving operations shall be suspended and inactive disturbed surface areas shall be stabilized. c) Fugitive dustgenerated by active operations, open storage piles, or from a disturbed surface area shall not result in such opacity as to obscure an observer's view to a degree equal to or greater than does smoke as dark or darker in shade as that designated as No. 2 on the Ringlemann Chart (or 40 percent opacity) . d ) All exposed soils be watered as needed to prevent dust density as described above �+ • and in order to prevent dust from visibly exiting the property. e) All haul trucks transporting soil , sand, or other loose material offsite shall be covered. f) All vehicle speeds on unpaved roads shal I be limited to 25 mph. O g) During construction the contractor shall , where feasible, utilize existing power sources (eg., power poles) or dean fuel (i .e. gasoline, biodiesel , natural gas) generators rather than temporary diesel power generators. D h ) Idling times shall be minimized either by shutting equipment off when not in use or reducing the maximum idling time to 5 minutes Clear signage shall be provided for construction workers at all access points. Signs shall be tied to queuing areas of the v construction site to remind off-road equipment operators that idling time is limited to a maximum of 5 minutes. O Z BI0-1 : Should work commence during the nesting season (February 1 through August X X US Fish and Wildlife Department IV. Biological 31 ), a preconstuction nesting bird survey shall be conducted bya qualified biologistno O Resources more than 7 days prior to the start of ground TT disturbing activities. This survey will indude the assessment of areas that can be used by = burrowing owl (Achene cunicularia), to ensure that the listed sped eswilI not be impacted . Accessible areaswithin 500 feet of construction shall be surveyed for active nests. Should an ^ active nest be identified, a disturbance-free buffer shall be established by the qualified IY biologist based on the needs of the species identified . The buffer shall be clearly marked by high-visibility material and shall remain in place until the nest is determined to be no longer active. Ground-disturbing activities, including the removal of trees, shall not occurwi thin the buffer. Should construction cease for a period of five days or more, an additional nesting bird Z Purvey shall be conducted. V. Cultural CR-1 : All workwithin 50-feet of the find should be halted until a qualified professional X X County Sheriff - Coroner Resources archaeologist can evaluate the significance of the find in accordnce with CRHR criteria. Work should not resume in the vicinity of the find until any required mitigation has been completed . CR-2 : If human remains are uncovered, compliance with Section 15064.5 (e) ( 1 ) of the CEQA Guidelines and Health and Safey Code Section 70505 is required. All project- related ground disturbances within 100- feet of the find should halt until the county coroner has been notified. If the coroner determines that the remains are Native American, the coroner will ask the NAHCto identify a Most Likely Descendant, whowill workwith the construction contractor, agency officials, and a qualified professional archaeologist to determine an appropriate avoidance strategy or other treatment plan . Project related ground disturbance in the vicinity of the find should not resume until the process detailed in CEQA Guidelines Section 15064.5 (e) has been completed .
