The Court declared that the U.S. Environmental Protection Agency (USEPA) has the authority to regulate emissions from new cars and trucks under the landmark environment law. Many chemical compounds found in the Earth’s atmosphere act as “greenhouse gases.” These gases allow sunlight to enter the atmosphere freely. When sunlight strikes the Earth’s surface, some of it is reflected back towards space as infrared radiation (heat). Greenhouse gases absorb this infrared radiation and trap the heat in the atmosphere. Over time, the trapped heat results in the phenomenon of global warming. Many gases exhibit these “greenhouse” properties. The sources of the majority of greenhouse gases come mostly from natural sources but are also contributed to by human activity and are shown in Figure F-1. It is not possible to state that a specific gas causes a certain percentage of the greenhouse effect because the influences of the various gases are not additive. Source: Energy Information Administration 2003 Figure F-1. Greenhouse Gas Emissions From Burning of Gas (Million Metric Tons of Carbon Equivalent) Figure F-2 displays the annual greenhouse gas emissions by sector in the United States. Most government agencies and military installations are just beginning to establish a baseline for their operations and their impact on the greenhouse effect. Since the USEPA has not promulgated an ambient standard or de minimis level for CO2 emissions for Federal actions, there is no standard value to compare an action against F-1 BW1 FOIA CBP 001518 in terms of meeting or violating the standard. Hence, we shall attempt to establish the effects on air quality as a result of the amount of CO2 produced by the Federal action and what could be done to minimize the impact of these emissions.

Combustion Estimates emissions from non-road equipment exhaust as well as painting. Fugitive Estimates fine particulate emissions from earthmoving, vehicle traffic, and windblown dust Grading Estimates the number of days of site preparation, to be used for estimating heavy equipment exhaust and earthmoving dust emissions Maintenance Emissions Estimates the total emissions from future maintenance of fencelines and access roads from mowers. Generator Emissions Estimates the total emissions from emergency generators to power construction equipment. AQCR Summarizes total emissions for the San Diego Intrastatet AQCR Tier Reports for 2001, to be used to compare project Tier Report to regional emissions.

Because the Proposed Action is several orders of magnitude below significance, the conclusion would be the same, regardless of whether future year budget data set were used.
