This measure is already included in the particulate emission projections in <br />the report. Haul trucks leaving the site shall also have a minimum freeboard distance of <br />12 tt, or cover payloads. <br /> <br />AQ-4 Sweep streets if silt is carried over to adjacent public thoroughfares. <br /> <br />AQ-5 Reduce traffic speeds on all unpaved road surfaces to 15 miles per hour or less. <br /> <br />AQ-6 Suspend grading operations during first and second stage smog alerts. <br /> <br />AQ-7 Suspend all grading opèrations when wind speeds (as instantaneous gusts) exceed 25 <br />miles per hour. <br /> <br />Maintain construction equipment engines by keeping them tuned. <br /> <br />AQ-8 <br />AQ-9 <br /> <br />Where feasible use low sulfur fuel for stationary construction equipment. <br /> <br />AQ-I0 Where feasible utilize existing power sources (e.g., power poles) or clean fuel <br />generators rather than temporary power generators. <br /> <br />AQ-l1 Provide on-site power sources during the early stages of the project. <br /> <br />AQ-12 Where feasible, use low emission on-site stationary equipment (e.g. clean fuels). <br /> <br />AQ-13 Spread soil binders on site, unpaved roads and parking areas. <br /> <br />AQ-14 Apply chemical soil stabilizers according to manufacturer's specifications to all inactive <br />construction areas (previously graded areas which remain inactive for 96 hours). <br /> <br />AQ-15 Reestablish groundcovers on construction site through seeding and watering of the site <br />that will not be disturbed for lengthy periods (such as two months or more). <br /> <br />4.1.1.4 Level of Significance of Impacts Related to Construction NO! and PMIO Emissions <br /> <br />The short term adverse impacts of the One Broadway Plaza project related to NOx and PMIO <br />emissions during construction cannot be mitigated to below a level of significance. <br /> <br />4.1.2 Impacts Related to Long Term Air Quality Impacts <br /> <br />4.1.2.1 Potentially Significant Adverse Impact Related to Long Term NO! Emissions <br /> <br />As described in detail in Section 3.4 (Air Quality) in the EIR, the One Broadway Plaza project <br />will result in adverse air quality impacts related to NOx emissions during long term operations. <br /> <br />4.1.2.2 Finding Related to Long Term NO!
