The particulate monitor (measuring PM1, PM2.5 and PM10) is not currently recording data. BCAMP is temporarily donating this instrument to the Porter Ranch community during the ongoing wildfire season to monitor pollutants which may be associated with health impacts. The H2S system is currently undergoing maintenance.

Benzene is a volatile organic compound (VOC) on the State of California's "Prop 65" list of known chemical carcinogens.… read more Benzene is a neurotoxin and can be found at low detections in ambient air.
Signs of benzene exposure can be dizziness, headaches, nausea, irritation to eyes and mucous membranes. Benzene is a constituent of crude oil and is associated to refinery emissions, petroleum product storage, vehicle tailpipe emissions, gas stations, other industrial emission sources, solvents, woodsmoke, tobacco smoking tobacco and cigarette smoke.
Long-term exposures to airborne benzene can be a cause of blood cancers and developmental/reproductive problems. Acute benzene poisoning can lead to heart arrhythmias, respiratory tract inflammation, pulmonary blood clots and hemorrhages, and affect kidneys and brain function.read less

Hydrogen sulfide can usually be smelled at low levels of concentration with immediate symptoms such as burning eyes,… read more coughing, fatigue, and shortness of breath. At moderate levels of concentration, exposure can cause severe eye and respiratory irritation, including fluid in the lungs, nausea and staggering. The results of exposure to high levels of concentration can be life threatening with effects such as the inability to breathe, convulsions, unconsciousness, coma, and death.
As prolonged exposure may result in the inability to distinguish the odor at all, measuring levels of concentration is invaluable in providing early detection to mitigate long-term health effects.read less

The purpose of this page is to evaluate the ability of the equipment installed as part of the Rodeo Fence-line Air Monitoring Program to detect and quantify gases that are ever-present in the air we breathe. The U.S. Environmental Protection Agency (EPA) suggests this is one way to assess the validity of data from fence-line air monitoring systems. Methane, nitrous oxide, and ozone are examples of gases that are always present. As per the EPA, should an air monitoring system fail to detect these gases within specific concentration ranges, the credibility of the data should be questioned.
In addition, at the request of individuals living in the community of Rodeo, the BCAMP monitoring program has relocated an ozone monitor to this community. The purpose of this is to measure the ozone in the ambient air using a technology that has been accepted as a Federal Equivalent Method. This monitor, as well as ozone data from the Bay Area Air Quality Management District (BAAQMD) ambient air monitoring systems, can be used to assess the overall quality of the data being presented to the community. The nearest BAAQMD monitors are located in Vallejo and San Rafael . It should be noted the actual location of BCAMP ozone monitor has been masked to respect the privacy of the host site.
BCAMP expresses its gratitude towards Phillips 66 for offering real-time data for methane, nitrous oxide, and ozone. It is noteworthy that no other refinery in the Bay Area currently offers such information for public scrutiny.

Since ozone is considered a regional air pollutant, the data from the Rodeo fence-line air monitoring system should track the BCAMP and BAAQMD air monitoring stations. The BCAMP air monitoring system is installed within the community of Rodeo and the BAAQMD air monitoring stations are located in the communities of Vallejo and San Rafael.

What is Benicia Community Air Monitoring Program (BCAMP)?
BCAMP is a non-profit established for the benefit of the community to monitor ambient air quality in Benicia. BCAMP independently holds, operates, and maintains air monitoring equipment at a community-based monitoring station and provides a public access website. BCAMP's mission is to sample and measure local air in real time; report and archive raw data on the website; and provide education on health risks as related to air quality.
Who operates the BCAMP station?
BCAMP has contracted Argos Scientific to operate and maintain our monitoring station's equipment and website. Established in 2006, Argos is a recognized expert in air quality monitoring throughout the world. Currently, Argos currently operates fence line monitoring systems at several Bay Area refineries and also supports community monitoring systems in southern California, and contributes research on state-of-the-art advances in monitoring technologies, working with state-wide Air District regulators.
