What does ISR mean in UNCLASSIFIED
ISR (Indirect Source Review) is an environmental regulatory program established by the United States Environmental Protection Agency (EPA) to address air pollution emissions from sources that are not directly regulated under the Clean Air Act (CAA). These sources include mobile sources, such as vehicles, and area sources, which are small stationary sources that individually emit small amounts of pollutants but collectively contribute to significant emissions.
ISR meaning in Unclassified in Miscellaneous
ISR mostly used in an acronym Unclassified in Category Miscellaneous that means Indirect Source Review
Shorthand: ISR,
Full Form: Indirect Source Review
For more information of "Indirect Source Review", see the section below.
What is ISR?
ISR focuses on controlling air pollution from these indirect sources by implementing measures that reduce emissions from vehicles and other portable equipment, as well as encouraging the use of cleaner fuels and technologies. The goal of ISR is to improve air quality and protect public health by reducing emissions of harmful pollutants, such as ozone, particulate matter, and nitrogen oxides.
Key Features of ISR
- Regulates air pollution from indirect sources, including mobile and area sources.
- Focuses on reducing emissions from vehicles, portable equipment, and other non-industrial sources.
- Promotes the use of cleaner fuels, alternative transportation options, and pollution control technologies.
- Works in collaboration with state and local governments to implement and enforce ISR programs.
Implementation of ISR
ISR is implemented through a variety of programs and regulations, including:
- Transportation control measures, such as promoting public transportation, ride-sharing, and walking/biking.
- Fuel efficiency standards for vehicles.
- Emission control standards for portable equipment.
- Regulations on solvent use and other industrial processes that contribute to area source emissions.
Benefits of ISR
- Improves air quality by reducing harmful air pollutant emissions.
- Protects public health by reducing exposure to air pollution.
- Promotes the development and use of cleaner technologies.
- Helps achieve compliance with the Clean Air Act and National Ambient Air Quality Standards (NAAQS).
Essential Questions and Answers on Indirect Source Review in "MISCELLANEOUS»UNFILED"
What is Indirect Source Review (ISR)?
ISR is a review process conducted by local air pollution control agencies that evaluates the indirect emissions associated with new or modified projects that attract or generate motor vehicle traffic. It aims to ensure that these projects do not contribute to air quality violations.
What types of projects trigger an ISR?
Projects that are likely to increase traffic congestion or vehicle miles traveled (VMT), such as new residential or commercial developments, shopping centers, or road expansions.
How is an ISR conducted?
The ISR process typically involves:
- Traffic impact analysis to estimate project-related VMT
- Emission modeling to calculate indirect emissions
- Mitigation measures to reduce emissions if necessary
What are the goals of ISR?
The primary goals of ISR are to:
- Prevent air quality deterioration from indirect emissions
- Ensure compliance with federal air quality standards
- Promote sustainable land use and transportation planning
Are all projects subject to ISR?
No, only projects that are likely to have significant traffic impacts are subject to ISR. Thresholds for triggering ISR vary by jurisdiction.
What are common mitigation measures required by ISR?
Mitigation measures may include:
- Promoting alternative transportation modes (e.g., public transit, walking, biking)
- Implementing traffic calming measures
- Encouraging energy-efficient building design
- Purchasing zero-emission vehicles for project operations
Final Words: ISR is an important environmental regulatory program that plays a crucial role in reducing air pollution from indirect sources. By implementing measures to control emissions from vehicles, portable equipment, and other non-industrial sources, ISR contributes to improving air quality and protecting public health. Collaboration between federal, state, and local governments is essential to the successful implementation and enforcement of ISR programs.
