<br />One Broadway Plaza <br />Environmental Impact Report <br /> <br />Findings and Facts in Support of Findings <br /> <br />8 <br /> <br />road hauling. This measure is already included in the particulate emission projections in the <br />report. Haul trucks leaving the site shall also have a minimum freeboard distance of 12", or <br />cover payloads. <br /> <br /> AQ-4 <br /> AQ-5 <br /> AQ-6 <br /> AQ-7 <br /> AQ-8 <br /> AQ-9 <br /> AQ-lO <br /> AQ-11 <br />8 AQ-12 <br /> AQ-13 <br /> AQ-14 <br /> AQ-15 <br /> <br />Sweep streets if silt is carried over to adjacent public thoroughfares. <br /> <br />Reduce traffic speeds on all unpaved road surfaces to 15 miles per hour or less. <br /> <br />Suspend grading operations during first and second stage smog alerts. <br /> <br />Suspend all grading operations when wind speeds (as instantaneous gusts) exceed 25 <br />miles per hour. <br /> <br />Maintain construction equipment engines by keeping them tuned. <br /> <br />Where feasible use low sulfur fuel for stationary construction equipment. <br /> <br />Where feasible utilize existing power sources (e.g., power poles) or clean fuel <br />generators rather than temporary power generators. <br /> <br />Provide on-site power sources during the early stages of the project. <br /> <br />Where feasible, use low emission on-site stationary equipment (e.g. clean fuels). <br /> <br />Spread soil binders on site, unpaved roads and parking areas. <br /> <br />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 />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 oflmpacts Related to Construction NOx 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 NOx 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 />8 <br /> <br />4.1.2.2 Finding Related to Long Term NOx Emissions <br /> <br />Resolution No. 2004-020 <br />Page 33 of 73 <br />
