to exceed CARB's screening threshold for high-traffic roadways, including Stoneridge Drive (even with extension of Stoneridge Drive, which is not part of the proposed project but is included in the City's General Plan)." (Draft EIR, page 3.2-18.) Exposure from the Livermore Airport would be the same with the Concurrent Extension because Livermore Airport operations would not be affected by the Concurrent Extension. F. ImpactAQ-6 Odors. The Draft EIR concludes that, under the Deferred F.xrension, the Project will result in less than significant odor impacts. (Impact AQ-6, Draft EIR, page 3.2-19.) Because the uses of the Project site would be the same with the Concurren[ Extension, the Project would not generate any significant additional odors as a result of the Concurrent Extension. G. ImpactAQ-7. GreenhouregasJeJ. The Draft EIR concludes that, under the Deferred Extension, the Project will result in less than significant greenhouse gas impacts. (Impact AQ-7, Draft EIR, page 3.2-19.) Mobile, area and indirect source generation rates will be the same with the Concurrent Extension because the number of vehicle trips generated and uses conducted by the Project will be the same. Greenhouse gas impacts therefore will be the same with the Concurrent Extension. 3.3 Biological Resources The Project will disturb the surface of the entire project site regardless of the Concurrent Extension or the Deferred Extension and, like the Draft EIR's analysis of the Existing Specific Plan Alternative (which assumes the Concurrent Extension), pose the same potential impacts to biological resources. The biological resources impacts of the Concurrent Extension arc therefore the same as those identified for the in the Drafr EIR. Construction of a second bridge across Arroyo Mocho to accommodate two additional lanes of Stoneridge Drive with the Concurren Extension is the only exception. However, as stated in the Final EIR, the mitiga[ion measures identified in the Draft EIR For bridge construction impacts (including Bio-2.1, 2.2, 2.3, 2.4, 3.2, 4.1, 4.2, 5.1, 6.1, 6.2, 6.3, and 7.1, 8.1, HY-4.1, and NO-2.1, 2.2 and 4.1, and CR-1) would also apply to reduce the impacts of the second Arroyo Mocho bridge to she same less than significant level as the impacts of the fist bridge. (Final EIR, page 3-24.) The Concurrent Extension therefore will not pose any new significant biological resources impacts or substantially increase the severity of such impacts beyond what is identified in the Draft EIR. 3.4 Hazards and Hazardous Materials The Concurrent Extension of an additional two lanes of Stoneridge Drive during buildout of the project will not alter the conclusions of the Draft EIR regarding potential hazards and hazardous materials impacts. Most such risks are associated with the proposed uses of the project site, which remain unchanged with the Concurrent Extension; the potential for a hazardous release with the Concurrent Extension is therefore the same as under the Deferred Extension. Any potential for exposure to hazardous materials due to earlier construction of Stoneridge Drive with the Concurrent Extension will, as with the Deferred Extension, be reduced to a less than siguificant caass~ ~ z-~~s±~s
