Monitoring

LRBOI’s Air Monitoring Station (AMS) is located at the tribe’s Justice Center.

• LRBOI monitors ambient (outdoor) air for:
  • Ground level ozone (O₃)
  • Particulate matter (dust) 2.5 microns in diameter and smaller (PM_2.5)
  • Meteorological conditions (Met)

Here is a brief description of each:

O₃

Ozone is a chemical similar to molecular oxygen, but it has three oxygen atoms instead of two. It is probably most famous for the Ozone Layer and the Ozone Hole over Antarctica. The ozone in the Ozone Layer is the same chemical that we are monitoring for at the ground level. Often people wonder why ozone up above is good, but ozone down here is bad. Simply put, ozone like many chemicals has good and bad properties. One of its good properties is that it blocks ultra-violet rays coming from the sun. Some of its bad properties are that it irritates our lungs and damages plant leafs. So, as you can see depending on where ozone is it can be helpful or detrimental to humans and the environment.

Ground level ozone is monitored in Michigan from April through September every year. This is because ground level ozone is not emitted as pollution, but rather created from the combination of pollutants in the air and hot weather “cooking” the pollutants to form ozone. Thus, ozone is only monitored for during the hottest months of the year.

The shoreline counties throughout West Michigan are heavily impacted from ozone due to pollution originating from the Chicago-Gary-Milwaukee corridor region of Lake Michigan. Studies have shown this time and time again to be true. LRBOI is working in conjunction with the State of Michigan’s Department of Environmental Quality (MDEQ) to monitor this situation. LRBOI’s monitoring data can be viewed real time on MDEQ’s web site along with all the othermonitoring stations around the state.

The State of Michigan also forecasts Ozone Action days to warn citizens of impending conditions that may lead to the heavy formation of ozone. MDEQ’s EnviroFlash program sends out notices to warn citizens a day or two in advance of hazardous air events.

PM_2.5

PM2.5 is basically dust that is 2.5 microns in diameter and smaller. However, it is not formed by the wearing away of rocks or other matter but rather by the chemical reactions inside engines and furnaces. PM2.5 is dangerous to human health because the particles are so small that they are readily absorbed into the bloodstream. This increases blood volume and thus blood pressure in the person breathing the pollutant. Furthermore, PM2.5 usually has more carcinogenic and haphazard chemicals in it than larger sizes of particulate matter. Also, the very small nature of it causes it to act more like a gas than like dust so it travels much further from its sources than larger particles of particulate matter.

All size ranges of particulate matter are monitored throughout the year. A sampler collects dust on a filter for twenty-four hours once every three days or once every six days. All the samplers in the entire country run on the same days to ensure a snapshot can be taken of what is going on throughout the United States. Obviously, the sites that sample once every six days only run every other run day that the sites that sample once in every three days run on.

Met

Met or meteorological conditions are monitored throughout the year as well. The met conditions monitored for are: temperature, wind speed, wind direction, barometric pressure and solar radiation. The monitoring of these conditions allows LRBOI staff to determine trends on weather’s affect and air pollution at the site. It also helps us to backtrack to possible sources and causes when there is an air pollution event.

Policy

LRBOI staff monitor decisions before the MDEQ and EPA for potential impacts to tribal members and the environment in the tribe’s service area. These can be anything from a change in permitting levels at a source, changes with the monitoring network, changes in the standards for “clean” air, as well as many other situations.

Services

LRBOI staff perform many services to members. In addition to monitoring the air, the staff also answers questions from members, comments on permit decisions in the service area and gives out notices of hazardous air events.

Report a Hazardous Air Event

If you wish to report a hazardous air event, you can use this form. Simply fill out the hazardous air event form (there should be 2 small check boxes in the upper right above the “Submit by Email” and “Print Form” buttons that will allow you to “Highlight Fields” and “Highlight Required Fields”. You should check the second checkbox to show you which fields need to be filled out in the form) and then choose either “Submit by Email” button in the upper-right of the form if you’d like to e-mail it in, or the “Print Form” button next to that if you’d like to print it out and mail it in yourself. When mailing it in using the postal mail, please use the following address to make sure it gets to the right place:
