City of Santa Ana -Park View at Town and Country Manor <br />Draft EIR Climate <br />The year 2020 greenhouse gas emission reduction goal of AB 32 corresponds with the mid -term <br />target established by 5 -3 -05, which aims to reduce California's fair -share contribution of greenhouse <br />gases in 2050 to levels that will stabilize the climate. Therefore, the threshold to be used for the Park <br />View at Town and Country Manor Project is as follows: <br />a.) Does the project comply with the provisions of an adopted greenhouse gas reduction plan or <br />strategy? If no such plan or strategy is applicable, would the project significantly hinder or <br />delay California's ability to meet the reduction targets contained in AB 32? <br />Because there is no adopted greenhouse gas reduction plan or strategy that was prepared by the City <br />of Santa Ana or the SCAQMD, this analysis will determine if the project would significantly hinder <br />or delay California's ability to meet the reduction targets in AB 32. <br />4.8.5 - Impact Analysis and Mitigation Measures <br />This section discusses potential climate change impacts associated with the development of the <br />project. Mitigation measures are provided where necessary. <br />Project and Cumulative Analyses <br />Impact 4.8 -1 The project could significantly hinder or delay California's ability to meet the <br />reduction targets contained in AB 32. The project would not result in a cumulative <br />impact to climate change. <br />Project Inventory <br />The threshold of significance used in this report is based on AB 32; therefore, this analysis is <br />restricted to greenhouse gases identified by AB 32, which include carbon dioxide, methane, nitrous <br />oxide, hydrofiuorocarbons, pertluorocarbons, and sulfur hexafiuoride. The project would generate a <br />variety of greenhouse gases during construction and operation, including several defined by AB 32 <br />such as carbon dioxide, methane and nitrous oxide. <br />The project may also emit greenhouse gases that are not defined by AB 32. For example, the project <br />may generate aerosols. Aerosols are short-lived particles, as they remain in the atmosphere for about <br />one week. Black carbon is a component of aerosol. A couple of studies have indicated that black <br />carbon has a high global warming potential; however, the IPCC states that it has a low level of <br />scientific certainty. Water vapor could be emitted from evaporated water used for landscaping, but <br />this is not a significant impact because water vapor concentrations in the upper atmosphere are <br />primarily due to climate feedbacks rather than emissions from project - related activities. The project <br />would emit nitrogen oxides and volatile organic compounds, which are ozone precursors. Ozone is a <br />greenhouse gas; however, unlike the other greenhouse gases, ozone in the troposphere is relatively <br />short-lived and can be reduced in the troposphere on a daily basis. <br />Certain greenhouse gases defined by AB 32 would not be emitted by the project. Pertluorocarbons <br />and sulfur hexafiuoride are typically used in industrial applications, none of which would be used by <br />Michael Brandman Associates 4.8 -7 <br />H\Cl t(PN -Rn) 327b32]003MMVB2]0030 Sec01 Clore Ch ge dac <br />
