City of Pleasanton–Spotorno Ranch Reduced Development Project Environmental Checklist Initial Study/Consistency Checklist 74 FirstCarbon Solutions https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2148/21480021/Consistency Checklist/21480021 Spotorno Ranch Consistency Checklist ScreenCheck.docx 1998 HVSP FEIR, there would be no change to the conclusions regarding any potential conflict with the applicable AQP. The 1998 HVSP FEIR included four mitigation measures related to the control of dust during construction (MM D1 through D4). The City proposes to refine these measures to reflect current best practices from the BAAQMD for the control of construction-period dust and particulates. Such refinements would improve the effectiveness of the measures included in the 1998 HVSP FEIR. These are minor clarifications and would not result in major revisions to the 1998 HVSP FEIR nor would these more protective features result in any new or more severe impacts. Therefore, the proposed project would not result in any peculiar effects and would not result in new or more severe impacts beyond what was previously analyzed in the HVSP FEIR. b) Air Quality Standard, Criteria Pollutants Would the project: Result in a cumulatively considerable net increase of any criteria pollutant for which the project region is non-attainment under an applicable federal or state ambient air quality standard? The 1998 HVSP FEIR concluded that the proposed project would not exceed BAAQMD significance thresholds for carbon monoxide (CO) and particulate matter (PM) during operation and impacts would therefore be less than significant. Construction emissions were discussed in terms of fugitive dust generated during site preparation and construction activities. The 1998 HVSP FEIR noted that the HVSP includes dust control measures for construction activities. These measures were adopted by the City as MM D1 through MM D4 in the 1998 HVSP FEIR: • During the construction period, all active unpaved construction areas (residential, golf course, roads, and infrastructure) shall be watered as needed, or treated with soil stabilizers, in order to avoid dust, and exposed stockpiles of dirt or sand shall be enclosed, covered, or treated with dust-preventives. • If soil material is carried over public or private roads, those roads shall be swept daily with water sweepers to control dust. • In graded construction areas, replacement vegetation shall be planted as quickly as possible. Graded areas that remain inactive for 10 days or more during the rainy season (October 1 to April 1) without permanent replanting should be hydroseeded or stabilized to inhibit dust. • Excavation and grading shall be suspended when winds (instantaneous gusts) exceed 25 miles per hour. The City proposes refinement of these measures to reflect current best practices from the BAAQMD for the control of construction-period dust and particulates. These minor modifications, listed at the end of this section, would improve the effectiveness of the measures included in the 1998 HVSP FEIR and would not require any major revisions to the 1998 HVSP FEIR or result in any new or more severe impacts. Therefore, the proposed project is consistent with the analysis of impacts in the
