  • Air quality specialist calls for black carbon standard

    Traditionally, ambient particulates have been measured gravimetrically according to their size. However, Jim Mills, Managing Director of Air Monitors, believes that the time has come to change or at least augment the way ambient particulates are monitored and regulated. Black Carbon (BC) is a term describing the fine particles that are produced as the result of incomplete combustion of fuels and ...

  • EPA strengthens air quality standard for nitrogen dioxide

    The U.S. Environmental Protection Agency today announced a new national air quality standard for nitrogen dioxide (NO2). This new one-hour standard will protect millions of Americans from peak short-term exposures, which primarily occur near major roads. Short-term exposures to NO2 have been linked to impaired lung function and increased respiratory infections, especially in people with asthma. ...

  • US air quality control standards for lead now 10 times stronger

    EPA dramatically strengthened the nation's air quality standards for lead, improving public health protection, especially for children. The new standards tighten the allowable lead level 10 times to 0.15 micrograms of lead per cubic meter of air (ug/m3). 'America's air is cleaner than a generation ago,' said EPA Administrator Stephen L. Johnson. 'With these stronger standards a new generation of ...

  • EPA announces most areas meet air quality standards for lead

    The U.S. Environmental Protection Agency (EPA) has determined that available air quality information indicates that 39 states are meeting the health-based national air quality standards for lead set in 2008. Based on 2008 to 2010 air quality monitoring data, EPA also determined that Illinois, Iowa, Kansas, Michigan and Puerto Rico each have one area that does not meet the agency’s health ...

  • San Diego County Meets National Air Quality Standard for Smog

    The U.S. Environmental Protection Agency announced that San Diego County has met the 1997 national health-based air quality standard for smog, also known as ground-level ozone. In addition, EPA has approved the state’s plan to maintain clean air standards for the more than three million residents of the San Diego area. “This is a victory for San Diego County residents, who are now ...

  • EPA to hold public hearing on air quality standards for sulfur dioxide

    WASHINGTON – The U.S. Environmental Protection Agency will hold a public hearing on the agency’s proposal to strengthen the nation’s sulfur dioxide (SO2) standards. Exposure to SO2 can aggravate asthma, cause respiratory difficulties, and result in emergency room visits and hospitalization. People with asthma, children, and the elderly are especially vulnerable to SO2’s effects. EPA is taking ...

  • Tougher Petroleum Refinery Standards Proposed to Protect Air Quality

    EPA is proposing to reduce emissions from new, modified, or reconstructed process units at petroleum refineries. The proposed amendments would update the existing standards of performance for petroleum refineries.

  • EPA proposes stronger air quality standards for nitrogen dioxide

    For the first time in more than 35 years, EPA has proposed to strengthen the nation’s nitrogen dioxide (NO2) air quality standard that protects public health. The proposed changes reflect the latest science on the health effects of exposure to NO2, which is formed by emissions from cars, trucks, buses, power plants, and industrial facilities and can lead to respiratory disease. “We’re updating ...

  • EPA sets public hearing dates on air quality standards for nitrogen dioxide

    EPA will hold two public hearings on the agency’s proposal to strengthen the nation’s nitrogen dioxide (NO2) standards. The proposed revisions would establish, for the first time, a one-hour NO2 standard, at a level between 80 and 100 parts per billion (ppb) and would retain the current annual standard of 53 ppb. The proposed changes reflect the latest science on the health effects of exposure to ...

  • EPA to hold public hearings on air quality standards for smog

    The U.S. Environmental Protection Agency will hold three public hearings on the proposal to strengthen the nation’s air quality standards for ground-level ozone, also called smog.
