Climate Change Chapter 14: Climate Change A. INTRODUCTION Since the publication of the DEIS, the design of certain Proposed Project elements has been refined, and in some instances, changes have been made in response to comments received as part of the public review process. While the size of the retail village on Site B has been reduced to approximately 315,000 gross square feet (gsf), and the size of the hotel has been reduced to approximately 210,000 gsf, this chapter conservatively retains the assumption of up to 350,000 gsf of retail village and 230,000 gsf of hotel presented in the DEIS. The increase in size of the arena on Site A from 690,000 gsf to 745,000 gsf has been incorporated in this chapter. This chapter evaluates the greenhouse gas (GHG) emissions that would be generated by the construction and operation of the Proposed Project and its resilience to climate change effects. Since the Proposed Project would be located outside of the potential future flood zones as projected by New York State for 2100, and since the Proposed Project would not introduce any major drainage infrastructure with the potential to affect local flooding conditions during severe precipitation events, the focus of the climate change analysis is on potential GHG emissions. As discussed in the Federal National Climate Assessment1 and New York State Department of Environmental Conservation (NYSDEC) policy,2 climate change is projected to have wide‐ ranging effects on the environment, including rising sea levels, increases in temperature, and changes in precipitation levels. Although this is occurring on a global scale, the environmental effects of climate change are also likely to be felt at the local level. The United States and New York State have established sustainability initiatives and goals for greatly reducing GHG emissions and for adapting to climate change. Additionally, the Town of Hempstead has registered as a participating community in New York State’s Climate Smart Communities program. NYSDEC recommends that agencies quantify GHG emissions where appropriate data inputs are reasonably available, with the appropriate level of review to assess the broad-scale effects of GHG emissions to inform decisions. Therefore, GHG emissions associated with the Proposed Project’s operations are quantified, and construction-related emissions are evaluated qualitatively. The guidance states that agencies should consider reasonable measures to lower the level of the potential GHG emissions. Therefore, the analysis reviews potential relevant measures aimed at reducing GHG emissions associated with the Proposed Project, and where practicable, the potential effect of various measures to reduce GHG emissions is evaluated. 1 U.S. Global Change Research Program. Climate Science Special Report: Fourth National Climate Assessment. Volume I. 2017. 2 NYSDEC. DEC Policy: Assessing Energy Use and Climate Change in Environmental Impact Statements. July 15, 2009. 14-1 July 2019 Belmont Park Redevelopment Civic and Land Use Improvement Project FEIS PRINCIPAL CONCLUSIONS The building energy use and vehicle use associated with the Proposed Project are estimated to generate between 163 and 172 thousand metric tons of carbon dioxide equivalent (CO2e) emissions per year. The Climate Smart Communities Pledge includes five elements by which a project’s consistency is evaluated: (1) Decrease community energy use; (2) Increase community use of renewable energy; (3) Realize benefits of recycling and other climate-smart solid waste management practices; (4) Reduce greenhouse gas emissions through use of climate-smart land use tools; and (5) Enhance community resilience and prepare for the effects of climate change. The Applicant is currently evaluating specific energy efficiency measures and design elements that may be implemented, and is seeking to achieve certification under the Leadership in Energy and Environmental Design (LEED) for Building Design and Construction rating system, version 4. The Applicant is committed at a minimum to achieve the prerequisite energy efficiency requirements under LEED and would likely exceed them. To qualify for LEED, the Proposed Project would be required to exceed the energy requirements of New York State’s Energy Conservation Construction Code (currently the same as ASHRAE 90.1-2013), resulting in energy expenditure lower than a baseline building designed to meet but not exceed the minimum building code requirements by approximately 12 to 20 percent for new construction. Furthermore, additional energy savings would likely be achieved via guidance for tenant build-out, which would control much of the building’s energy use and efficiency, but those are unknown at this time. The Proposed Project’s commitment to building energy efficiency, exceeding the energy code requirements, would ensure consistency with the decreased energy use goal defined in the Climate Smart Communities Pledge as part of the Town’s GHG reduction goal. The Proposed Project would also support the other GHG goals by virtue of its proximity to public transportation, reliance on natural gas, LPG, or electricity (rather than fuel oil), commitment to construction air quality controls, and the fact that as a matter of course, construction in the New York City metropolitan region uses recycled steel and includes cement replacements. All of these factors demonstrate that the proposed development supports the GHG reduction goal. Therefore, based on the commitment to energy efficiency and by virtue of location and nature, the Proposed Project would be consistent with the Town’s emissions reduction goals, as defined in the Climate Smart Communities Pledge. Since the Proposed Project would be located outside of the potential future flood zones as projected by New York State, all components of the Proposed Project would be located well above flood elevations out to 2100 and beyond. A stormwater analysis was performed for the Proposed Project (see Chapter 9, “Water Resources”), and found that infrastructure for the Proposed Project would be able to accommodate peak precipitation under future conditions, and implementation of the Proposed Project would not have a significant adverse impact on on-site or off-site stormwater management facilities, stormwater runoff on surrounding communities, and would not exacerbate local flooding conditions during severe precipitation events. B. GREENHOUSE GAS EMISSIONS POLLUTANTS OF CONCERN GHGs are those gaseous constituents of the atmosphere, both natural and anthropogenic, that absorb and emit radiation at specific wavelengths within the spectrum of infrared radiation emitted 14-2 Chapter 14: Climate Change by the Earth’s surface, the atmosphere, and clouds. The general warming of the Earth’s atmosphere caused by this phenomenon is known as the “greenhouse effect.” Water vapor, carbon dioxide (CO2), nitrous oxide (N2O), methane, and ozone are the primary GHGs in the Earth’s atmosphere. There are also a number of entirely anthropogenic GHGs in the atmosphere, such as halocarbons and other chlorine- and bromine-containing substances, which also damage the stratospheric ozone layer (and contribute to the “ozone hole”). Since these compounds are being replaced and phased out due to the 1987 Montreal Protocol, there is no need to address them in GHG assessments for most projects. Although ozone itself is also a major GHG, it does not need to be assessed as such at the project level since it is a rapidly reacting chemical and efforts are ongoing to reduce ozone concentrations as a criteria pollutant (see Chapter 12, “Air Quality”). Similarly, water vapor is of great importance to global climate change, but is not directly of concern as an emitted pollutant since the negligible quantities emitted from anthropogenic sources are inconsequential. CO2 is the primary pollutant of concern from anthropogenic sources. Although not the GHG with the strongest effect per molecule, CO2 is by far the most abundant and, therefore, the most influential GHG. CO2 is emitted from any combustion process (both natural and anthropogenic); from some industrial processes such as the manufacture of cement, mineral production, metal production, and the use of petroleum-based products; from volcanic eruptions; and from the decay of organic matter. CO2 is removed (“sequestered”) from the lower atmosphere by natural processes such as photosynthesis and uptake by the oceans. Methane and N2O also play an important role since the removal processes for these compounds are limited and because they have a relatively high impact on global climate change as compared with an equal quantity of CO2. Emissions of these compounds, therefore, are included in GHG emissions analyses when the potential for substantial emission of these gases exists. The United States Environmental Protection Agency (EPA) identifies seven types of GHGs that are relevant for GHG inventory purposes: CO2, N2O, methane, hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), nitrogen trifluoride (NF3), and sulfur hexafluoride (SF6). The analysis focuses mostly on CO2, N2O, and methane. There are no significant direct or indirect sources of HFCs, PFCs, NF3, or SF6 associated with the Proposed Project. To present a complete inventory of all GHGs, component emissions are added together and presented as CO2e emissions—a unit representing the quantity of each GHG weighted by its effectiveness using CO2 as a reference. This is achieved by multiplying the quantity of each GHG emitted by a factor called global warming potential (GWP).

  • The Clean Power Plan: an Enormous Economic Opportunity for Texas
    The Clean Power Plan: An Enormous Economic Opportunity for Texas The U.S. Environmental Protection Agency’s (EPA) Clean Power Plan establishes the nation’s first-ever limits on carbon pollution from existing power plants. The plan sets a carbon emissions reduction goal for each state in order to achieve a national power sector emissions reduction of 32 percent relative to 2005 levels by 2030. Texas’ target is to improve its power sector’s emissions intensity 33 percent relative to 2012 levels by 2030. Although Texas is the #1 carbon polluter in the country, that’s not the whole story. This is: Texas already produces more wind power than any other state. Texas ranks first in the nation for solar energy potential. Texas has greater potential to deploy energy efficiency than any other state. In fact, through current market trends alone, Texas will be 88% of the way toward meeting its 2030 Clean Power Plan target. Amplifying current trends Texas is already moving away from traditional coal generation and toward homegrown, cleaner energy sources, driven by deregulation of the electricity market, the development of the massive highway of transmission lines built to carry West Texas wind to cities throughout the state – the Competitive Renewable Energy Zone (CREZ), and technological progress. Plus, this trend toward cleaner, more affordable power – which has coincided with a notable reduction in wholesale electricity prices – should continue.

  • Components of the Clean Power Plan: Setting State Goals to Cut
    COMPONENTS OF THE CLEAN POWER PLAN SETTING STATE GOALS TO CUT CARBON POLLUTION On August 3, President Obama and EPA announced the Clean Power Plan – a historic and important step in reducing carbon pollution from power plants that takes real action on climate change. Shaped by years of unprecedented outreach and public engagement, the final Clean Power Plan is fair, flexible and designed to strengthen the fast‐growing trend toward cleaner and lower‐polluting American energy. With strong but achievable standards for power plants, and customized goals for states to cut the carbon pollution that is driving climate change, the Clean Power Plan provides national consistency, accountability and a level playing field while reflecting each state’s energy mix. It also shows the world that the United States is committed to leading global efforts to address climate change. HOW THE CLEAN POWER PLAN WORKS The Clean Air Act – under section 111(d) – creates a partnership between EPA, states, tribes and U.S. territories – with EPA setting a goal and states and tribes choosing how they will meet it. The final Clean Power Plan follows that approach. EPA is establishing interim and final carbon dioxide (CO2) emission performance rates for two subcategories of fossil fuel‐fired electric generating units (EGUs): o Fossil fuel‐fired electric generating units (generally, coal‐ fired power plants) o Natural gas‐fired combined cycle generating units To maximize the range of choices available to states in implementing the standards, and to utilities in meeting them, EPA is establishing interim and final statewide goals in three forms: o A rate‐based state goal measured in pounds per megawatt hour (lb/MWh); o A mass‐based state goal measured in total short tons of CO2; o A mass‐based goal with a new source complement measured in short tons of CO2.

  • Community Comments on EPA's Advance Notice of Proposed
    Community Comments on EPA’s Docket No. EPA-HQ-OAR-2017-0545 Advance Notice of Proposed Rulemaking: State Guidelines for Greenhouse Submitted via regulations.gov Gas Emissions from Existing Electric February 26, 2018 Utility Generating Units The undersigned organizations oppose EPA Administrator Scott Pruitt’s ongoing campaign to repeal the Clean Power Plan and leave Americans without any meaningful nation-wide limits on carbon pollution from power plants. Repealing the Clean Power Plan and replacing it with weak limits on power plant carbon pollution—or nothing at all—is a reckless course of action that places the health and safety of millions of Americans at greater risk from climate change and higher levels of deadly air pollution. America’s power plants are our nation’s largest stationary source of the carbon pollution that is changing our climate and posing a dire threat to public health and welfare in the United States and worldwide. Communities and families across the country are already facing the devastating impacts of climate change in the form of more intense hurricanes, rising sea levels, heat waves, wildfires and other extreme weather events. We need to take urgent action to dramatically reduce the pollution that is destabilizing our climate, and it is essential to curb this pollution from the power sector. Deep emission reductions from the nation’s fossil fuel power plants are readily attainable, as shown by the clean energy and energy efficiency progress that is already underway and spurring innovation and job creation across the country. Despite the urgent need for action, Administrator Pruitt has proposed an outright repeal of the Clean Power Plan, one of America’s most important steps to address climate change and the only nation-wide limit on power plant carbon pollution.

  • Why Greenhouse Gas Regulation Under Clean Air Act Section 111(D) Need Not, and Should Not, Stop at the Fenceline
    In Defense of the Clean Power Plan: Why Greenhouse Gas Regulation Under Clean Air Act Section 111(d) Need Not, and Should Not, Stop at the Fenceline Eric Anthony DeBellis In the summer of 2014, the Supreme Court heard a challenge to the Environmental Protection Agency’s first-ever Clean Air Act regulation of greenhouse gases from “major” stationary sources like power plants and factories. In Utility Air Regulatory Group v. Environmental Protection Agency, the Court struck down the agency’s special definition of “major” sources for greenhouse gases and removed its broader authority to require permits based solely on greenhouse gas emissions. The Court thus limited the agency’s jurisdiction to sources that already require permits for conventional air pollutants—a category accounting for nearly all emissions the agency sought to regulate. Hence, the case hardly affected the agency’s new permitting program, but the Court’s reasoning raised a concern that may have broader implications. Writing for the majority, Justice Antonin Scalia voiced fears of regulatory overreach into the lives of common citizens engaged in innocuous behavior, proclaiming any regulation that could apply to owners of small, nonindustrial sources would face skepticism from the Court. These regulatory overreach concerns may arise again in a legal challenge to the agency’s largest greenhouse gas rule to date: a program to reduce energy sector emissions by 30 percent by 2030 known as the “Clean Power Plan.” After the Court’s decision, many commentators have asked whether the Clean Power Plan’s approach of regulating states’ energy sectors as a whole, including operations that take place “beyond the fenceline” of individual plants, will survive judicial review.

It has been accepted for inclusion in ESSAI by an authorized editor of DigitalCommons@COD. For more information, please contact [email protected]. Lauzadis: The Clean Power Plan The Clean Power Plan by Matas Lauzadis (Chemistry 1551) he Clean Power Plan, originally proposed by the EPA in June 2014, was an Obama administration policy which sought to combat human-caused climate change. The plan Toriginally aimed to lower carbon dioxide emissions created by power generators by 32% relative to the 2005 levels by reducing emissions and increasing the use of renewable energy and conservation of energy. Logistically, the plan required individual states to meet carbon dioxide emission standards. If the state failed to create a plan and submit it to the EPA, a plan would be imposed upon it. The EPA estimated the Clean Power Plan (CPP) would reduce pollutants contributing to smog and soot by 25 percent, yielding a net health and climate benefit of $25-45 billion per year after 2030. The focus on carbon dioxide (CO2) emissions from coal plants was supported by the Energy Information Administration’s (EIA) claim that coal in 2015 produced 1.3 billion metric tons of carbon dioxide, which was about 71% of CO2 emissions from the electric power sector.

  • EPA's Clean Power Plan: Highlights of the Final Rule
    EPA’s Clean Power Plan: Highlights of the Final Rule Jonathan L. Ramseur Specialist in Environmental Policy James E. McCarthy Specialist in Environmental Policy September 27, 2016 Congressional Research Service 7-5700 www.crs.gov R44145 EPA’s Clean Power Plan: Highlights of the Final Rule Summary On August 3, 2015, the Environmental Protection Agency (EPA) finalized regulations that address carbon dioxide (CO2) emissions in the electric power sector. The Clean Power Plan (CPP) final rule requires states to submit plans that would reduce carbon dioxide (CO2) emissions or emission rates—measured in pounds of CO2 emissions per megawatt-hour of electricity generation—from existing fossil fuel electricity generating units. EPA estimates that in 2030, the CPP will result in CO2 emission levels from the electric power sector that are 32% below 2005 levels. The CPP is the subject of ongoing litigation in which a number of states and other entities have challenged the rule. On February 9, 2016, the Supreme Court stayed the CPP for the duration of the litigation. The CPP therefore currently lacks enforceability or legal effect, and if the rule is ultimately upheld, at least some of the deadlines would have to be delayed. For example, the final rule established a deadline of September 6, 2016, for states to submit to EPA plans to comply with the rule with the option for a two-year extension (September 6, 2018). If a state fails to submit a satisfactory plan by EPA’s regulatory deadline, the Clean Air Act directs EPA to prescribe a plan for the state, often described as a federal implementation plan.

  • EPA's Proposal to Repeal the Clean Power Plan: Benefits and Costs
    EPA’s Proposal to Repeal the Clean Power Plan: Benefits and Costs Kate C. Shouse Analyst in Environmental Policy February 28, 2018 Congressional Research Service 7-5700 www.crs.gov R45119 EPA’s Proposal to Repeal the Clean Power Plan: Benefits and Costs Summary In 2015, when the U.S. Environmental Protection Agency (EPA) promulgated the Clean Power Plan to reduce greenhouse gas emissions from fossil-fueled electric power plants, it concluded that the benefits of reducing emissions would outweigh the costs by a substantial margin under the scenarios analyzed. EPA estimated benefits ranging from $31 billion to $54 billion in 2030 and costs ranging from $5.1 billion to $8.4 billion in 2030, when the rule would be fully implemented. In proposing to repeal the rule in October 2017, EPA revised the estimates of both its benefits and costs, finding in most cases that the benefits of the proposed repeal would outweigh the costs of the proposed repeal. However, EPA found that under other assumptions, the costs of the proposed repeal would outweigh the benefits of the proposed repeal. This report examines the changes in EPA’s methodology that led to the revised conclusions about how benefits compare to costs. Three changes to the benefits estimates of the proposed repeal drive the agency’s new conclusions. First, it considered only domestic benefits of the Clean Power Plan in its main analysis, excluding benefits that occur outside the United States. Second, it used different discount rates, including one higher rate, than the 2015 analysis to state the present value of future climate benefits expected from the Clean Power Plan.
