The Clean Air Act provides legal mechanisms to address the transport pollution problem. The Clean Air Act does not give states the right to act according to their own deadlines. As a result, EPA has developed a policy to resolve this tension between deadlines. This policy is designed to allow upwind regions to accept responsibility for pollution. In doing so, EPA is fulfilling Congress's intent.
The EPA's Attainment Date Extension Policy is an appropriate interpretation of the Clean Air Act provisions. EPA acknowledges that upwind areas may not be able to achieve their goals as quickly as they want. EPA has therefore extended the attainment deadlines in upwind areas. It has also restricted the NOX submission extension for areas with documented transport difficulties. If an area upwind fails to achieve its goals, it may need to exercise more stringent control.
EPA had no authority to assign responsibility for transport until 1998. EPA had a good understanding of the scope and magnitude of the transport polluting problem at that point. Even after this, EPA was unable to get adequate redress for transported pollution until the OTAG process was completed. EPA interpreted section 181(a), Clean Air Act, according to its understanding of the transport pollution problem.
The EPA's Attainment Strategy and Guidance states that the transport of pollutants is an integral part the nonattainment of an area. According to this assumption, an upward-wind state cannot rely upon segregation for attainment. EPA could not assess whether upwind states had taken sufficient control measures, or if they were failing to take necessary steps to reduce their own pollution, until 1998.
EPA was able to better understand the transport pollution problem by 1999. EPA had analyzed the regional transport pollution and associated air quality and determined that the upwind areas were responsible for the transport of pollution to their downwind regions. EPA and the states worked together to determine the responsibilities for transport. The initial regional transport analysis took over a decade to complete. In 1999, EPA declared that transport was its responsibility. EPA admitted that it was difficult for them to create a comprehensive approach because they didn't have a clear understanding of how to measure the emissions.
EPA has replied to commenters that questioned the EPA’s Attainment date extensions policy. Although EPA believes that the policy is in line with Congress's intent it has been criticized for not providing meaningful relief to upwind regions. EPA believes the policy should be applied only as a last resort. EPA still believes that the graduated attainment framework is important, despite acknowledging this fact by the EPA.
Although EPA reclassified Phoenix moderately under section 179B, this provision was not intended to be a punishment. It was meant to protect the downwind from the transport pollution problem. Section 181 (a) of Clean Air act regulates the classification of ozone-nonattainment regions based on design values. EPA and states collaborated to address transportation issues during the OTAG process.
FAQ
What is the impact of climate change on oceans and marine life around the world?
What are the effects of climate change on oceans and marine life around the globe?
Climate change has been significantly affecting the world's oceans and the associated marine life since its onset. Constant oceanic heat from the depletion in the ozone layer causes major disruptions in marine ecosystems. This leads to coral bleaching, and decreases in species.
Unpredictable weather conditions and stronger storms are also linked to climate change, leading to extreme surges in sea levels that can prove deadly for coastal areas. Also, rising temperatures can reduce the oxygen levels in the water system, leading to "deadzones" that are areas with less marine life.
Ocean acidification is also being caused by excessive carbon dioxide in the atmosphere. Ocean acidification causes an increase in pH which affects the vital functions of animals such as crabs, clams, and oysters that cannot adapt to changing conditions.
Higher temperatures can alter the natural habitats of certain species by changing their locations or shrinking them, making them uninhabitable. This increase in ocean stress accelerates already high extinction rates amongst many species worldwide causing a severe imbalance between predators and prey that might eventually lead to complete extinctions.
The ripple effect of climate change affects entire ecosystems. It can directly or indirectly impact multiple species through evaporation, lower water volumes, and sharp temperature shifts. Global climate change continues to wipe out entire species of life on Earth, transforming our future lives not only on the land but also deep below the oceans' surface.
What is the current climate like? How is it changing?
The global climate is currently experiencing unprecedented uncertainty and change. Temperatures are increasing dramatically due to increased atmospheric carbon dioxide, which is leading to heat waves, droughts and changes in rainfall patterns.
These changes are already having a profound impact on ecosystems around the world, causing extinctions and disruption of habitats. They are also threatening millions of people's lives and livelihoods, particularly in areas where there is already resource scarcity.
Increased average surface temperatures, which are caused by human activity, have led to an increase of extreme weather events, such as hurricanes or cyclones. As temperatures continue their climb, this trend is expected to continue.
Climate change has global consequences. It can affect everything, from food insecurity and displacement to communities that are forced to relocate due to severe weather events or rising sea levels. Climate change is also exacerbating existing social inequalities by disproportionately affecting marginalized communities that do not possess the resources or knowledge necessary for adapting effectively.
There has been progress in some areas, such as the reduction of carbon emissions or initiatives for renewable energy in certain countries. However, there is no global initiative that can be taken to effectively mitigate these changes. For us to avoid further disruption and devastation due to climate change, all nations need to come together and take urgent actions now. At the same time, we must plan for adaptation in an uncertain world.
How can the world make a transition to a more sustainable future given the challenges presented by climate change?
Sustainability means being able to provide for current needs and not compromise future generations' ability. An urgent need exists to act to eliminate our dependency on finite natural resources and to shift towards a more sustainable method of using them.
It is crucial that we reexamine our consumption and production patterns, as well our dependence on fossil fuels, in order to move towards a sustainable future. We must seek out new technologies, renewable sources of energy, and systems that reduce harmful emissions while still meeting our everyday needs.
Additionally, sustainability must be approached from a holistic perspective. This means taking into account all aspects of production, from the materials used, waste management, and reuse strategies, to energy utilization in transportation and industry. There are many options available, including the use of renewable energies like solar, wind and hydropower, improved waste management systems, increased efficiency in agriculture, improved transport networks, green building regulations, and sustainable urban planning.
This goal requires behavioral changes from individuals in all sectors of society. Education programs are needed which will support people in understanding the issues related to climate change and how they can contribute positively towards a more sustainable world through micro-actions such as reducing food waste or adopting low-carbon lifestyles.
We can only make significant progress in creating sustainable environments for the future by working together with industry leaders, citizens, and governments.
What are the ways climate change can be mitigated or reduced?
There are many steps that can be taken in order to reduce and mitigate climate change's effects. These include reducing greenhouse emissions by using greener energy sources and better energy practices. It's also important to educate the public about climate change. This will encourage people to be responsible for their actions.

How To
How to make your home more efficient and fight climate change
Your home's energy efficiency is one of the most cost-effective ways to cut your carbon footprint, lower your utility bills, and improve your quality of life.
You must ensure that your home is properly insulated. Make sure windows and doors are correctly fitted, look for drafts around pipes and vents, add weather stripping where necessary, and fill any gaps around window frames or door frames with caulking.
Insulate your walls, ceilings, and floors to maximize energy efficiency. Inspect the attic for potential air leaks.
Lighting accounts for up to 18% of total household electricity usage so make sure you switch to LED light bulbs which use up to 80% less electricity than traditional incandescent ones! Installing motion sensors and timers will also help you save additional money by turning off lights as needed.
A newer model is more efficient and can help reduce your energy bills. Consider getting a programmable thermostat that allows you to set temperatures based on when people are home or away from the house.
All windows should be replaced by double-glazed units that are more energy efficient and less heat escaping. Look into buying low-flow showerheads which reduce water consumption while maintaining adequate pressure levels.
ENERGY STAR rated appliances are more efficient than non-certified models and can use as much as 50% less power. You can save a lot of energy by not plugging in electronic devices such as TV boxes or phone chargers when they are not being used.
These steps can make living at home easier and less stressful.
