Vehicular emissions and air quality standards

Top of Page Air Pollution Challenges: Climate Change EPA determined in that emissions of carbon dioxide and other long-lived greenhouse gases that build up in the atmosphere endanger the health and welfare of current and future generations by causing climate change and ocean acidification. Long-lived greenhouse gaseswhich trap heat in the atmosphere, include carbon dioxide, methane, nitrous oxide, and fluorinated gases.

Title V permitting requirements What is a Title V permit? Under this federal law, state and local air districts, including the Valley Air District, are required to issue these new comprehensive operating permits to major sources of air pollution.

For example, in order to simplify the application process, the District has developed specialized application forms for both initial Title V permitting and modifications. Also, for some types of commonly permitted equipment, the District has developed EPA- approved general permit templates, which eliminate the need for applicants to address many applicable requirements on a unit-by-unit basis.

Who is required to obtain a Title V permit? Sources currently required to obtain Title V permits include: Are there exemptions to Title V requirements? Major sources whose actual emissions are or can be reduced below Title V thresholds may be exempt from Title V requirements in one of two ways: Facility operators interested in pursuing these options may contact Permit Services staff at their regional offices for more information.

How can I find out more about Title V? The pre-construction approval, called an Authority to Construct, is required by air pollution regulatory agencies such as the Valley Air District to help ensure that business will not build or modify equipment that does not operate in compliance with air pollution regulations.

Please visit the permits page for more information. How long does it take to obtain an Authority to Construct? Generally, applications are processed in the order that they are deemed complete. Depending on the number of complete applications received and staffing resources, processing begins as soon as possible after the application is deemed complete.

Once an applicant has provided all of the information needed to process an application, the District sends a written receipt for the completed packet. By law, the District has up to days from the date an application is deemed complete to take final action to approve or deny the application.

Recognizing the enormous costs that permitting delays can cause, the District has implemented a number of permit streamlining measures to reduce permit processing time.

Depending on the complexity of the project, some applications require less than one hour of processing, others require more than one hundred. If the application is subject to public noticing provisions, a day public commenting period is required.

For a more accurate estimate on permit turnaround time, please contact permitting staff at the district regional permit office where the equipment will be located. This marks the beginning of a day period for final approval or denial of the application.

Some applications require less than one hour of processing, others require more than one hundred. If the application is subject to public notice, a day public commenting period is required. What can be done to minimize the amount of time it takes to obtain an Authority to Construct?

Submitting a complete application with all the information requested in the instructions is the best way to reduce the application processing time. CAPP consultants have completed District training and passed a comprehensive examination that allows them to submit a complete application, a draft engineering analysis, and draft permit conditions.

This enables the District to do a final review of the CAPP submittal, bypassing the need for District staff to perform these steps.An air pollutant is a material in the air that can have adverse effects on humans and the ecosystem.

The substance can be solid particles, liquid droplets, or gases. Aug 10,  · In California enacted legislation requiring the state Department of Public Health to establish air quality standards and necessary controls for motor vehicle emissions.

California law continues to mandate California ambient air quality standards (CAAQS), which are often more stringent than national standards.

Bharat stage emission standards (BSES) are emission standards instituted by the Government of India to regulate the output of air pollutants from internal combustion engines and Spark-ignition engines equipment, including motor standards and the timeline for implementation are set by the Central Pollution Control Board under the Ministry of Environment & Forests and climate change.

Due to its preexisting standards and particularly severe motor vehicle air pollution problems in the Los Angeles metropolitan area, In , the United States the Environmental Protection Agency also issued regulations to limit formaldehyde emissions.

Air quality standards. Air Quality Monitoring System (AQMS) Monitoring air quality is essential for local authorities as well as for major public and private industries to understand and prevent air pollution and assess emission sources, in order to preserve health and contribute to the fight against the greenhouse effect.

The entire nation meets the carbon monoxide air quality standards, largely because of emissions standards for new motor vehicles under the Clean Air Act.
