GAO reviewed the Environmental Protection Agency's (EPA) new rule on primary national ambient air quality standards for nitrogen dioxide. GAO found that (1) final rule revises the primary nitrogen dioxide national ambient air quality standards in order to provide requisite protection of public health; and (2) EPA complied with the applicable requirements in promulgating the rule. (a) This appendix explains the data handling conventions and computations necessary for determining when the primary national ambient air quality standards for oxides of nitrogen as measured by nitrogen dioxide (“NO 2 NAAQS”) specified in are met. Nitrogen dioxide (NO 2) is measured in the ambient air by a Federal reference method (FRM) based on appendix F to this part or by a.
The Clean Air Act requires the EPA to set National Ambient Air Quality Standards (NAAQS) for criteria pollutants, including sulfur dioxide. The largest sources of SO2 emissions nationally are fossil fuel combustion at power plants (73 percent) and other industrial facilities (20 percent). Ambient Air Quality Standards (NAAQS) for Nitrogen Dioxide (NO2). On or about May 4, , the EPA will make available for public review the document titled Review of the Primary National Ambient Air Quality Standards for Nitrogen Dioxide: Risk and Exposure Assessment Planning Document (REA Planning Document).
Ambient air quality refers to the condition or quality of air surrounding us in the outdoors. National Ambient Air Quality Standards are the standards for ambient air quality set by the Central Pollution Control Board (CPCB) that is applicable nationwide. The CPCB has been conferred this power by the Air (Prevention and Control of Pollution) Act, The National Ambient Air Quality Standards (NAAQS) are determined by the EPA in accordance with the Clean Air Act. Ambient Air Quality Standards include primary standards directed at protecting public health and secondary standards aimed at promoting public welfare. Standards have been drawn up for six “criteria” pollutants.

On April 6,based on a review of the full body of scientific evidence, EPA issued a decision to retain the current national ambient air quality standards (NAAQS) for oxides of nitrogen (NOx).
The EPA has concluded that the current NAAQS protect the public health, including the at-risk populations of older adults, children and people with.

National Ambient Air Quality Standards (NAAQS), in the United States, allowable levels of harmful pollutants set by the Environmental Protection Agency (EPA) in accordance with the Clean Air Act (CAA).
The CAA established two types of standards for ambient air quality. Primary standards concern the minimum level of air quality necessary to keep people from becoming ill and therefore are aimed.

Rule Summary; Rule History; Additional Resources; Rule Summary. Inbased on its review of the air quality criteria for oxides of nitrogen and the primary NAAQS for oxides of nitrogen as measured by nitrogen dioxide (NO 2), EPA made revisions to the primary NO 2 NAAQS in order to provide requisite protection of public health.
Specifically, EPA established a new 1-hour standard at a level.

Nitrogen Dioxide National Ambient Air Quality Standards. Nitrogen dioxide (NO 2) is one of a group of highly reactive gasses known as "oxides of nitrogen," or "nitrogen oxides (NO x).")." Other nitrogen oxides include nitrous acid and nitric acid. While EPA’s National Ambient Air Quality Standard covers this entire group of NO x, NO 2 is the component of greatest interest and the indicator.

Size: KB. EPA’s Office of Air and Radiation has requested advice and review to help in developing an integrated plan for conducting the science, risk-exposure, and policy assessments that will provide the basis for EPA's decisions on the primary (health-based) standards for the.
X.-M. Hu, in Encyclopedia of Atmospheric Sciences (Second Edition), Description of Pollutants in the Air. The United States Environmental Protection Agency (U.S.
EPA) set National Ambient Air Quality Standards (NAAQS) for six principal pollutants in s to provide protection for public health and the environment. These six principal pollutants are called ‘criteria’ pollutants. Literature comparing national ambient air quality standards (AAQSs) globally is scattered and sparse.
Twenty-four hour AAQSs for particulate matter Cited by: The pollutants which are used to define the quality of air are termed the criteria pollutants, namely, particulate matter, sulfur oxides, carbon monoxide, nitrogen dioxide, lead, and photochemical oxidants (ozone), as listed in Table Additional pollutants are regulated under the Clean Air Act; however, clean air is defined in terms of only Cited by:.
