Air Monitoring

The Air Monitoring Section maintains and gathers data from an extensive air pollution and meteorological network located throughout the City of Toledo and Lucas County. Pollutants of concern are ozone and particulate matter. See Link Air Monitoring Sites and National Ambient Air Standard


Ozone is a colorless, odorless gas composed of three oxygen atoms that can be protective or harmful, depending on where it is found in the atmosphere.

  • Is naturally occurring in the stratosphere, about 10-30 miles above the Earth's surface, which in turn protects our planet from the sun's ultraviolet (UV) radiation.
  • The stratospheric ozone has been thinned by man-made chemical refrigerants like chlorofluorocarbons (CFCs), methyl bromide, and carbon tetrachloride. This  means that more UV radiation is reaching the troposphere and more troposphere ozone (ground level) is being created.
  • Ozone at ground level (troposphere) is formed when nitrogen oxides and volatile organic compounds emitted by cars, power plants, refineries, industrial boilers, chemical manufacturers, and other sources react with sunlight



Particulate matter (PM) in the ambient air comes from a variety of sources and has an equally broad range of size, composition, and other characteristics.

  • Composed of particles that are 2.5 microns (micrometer) in size that are directly emitted as products of chemical reactions of gases in the atmosphere
  • Numerous scientific studies have provided evidence that PM in the ambient air is associated with increases in daily morbidity and mortality
  • Examples of directly emitted particles include those from combustion sources such as residential wood combustion, agricultural open burning, coal and oil fired power plants and industries, as well as dust particles from roads and fields.

At our department, we sample daily to obtain the concentration of PM2.5 in the ambient air. We also use special filters that allow us to see, not only the size, but the type of particulate in the ambient air.

Noise Logo 5


The city recognizes that this is necessary to preserve, protect, and promote public health The City of Toledo has implemented an anti-noise law to reduce ambient noise levels in the City.. Our division is responsible for enforcing the industrial Anti-Noise Law, Chapter 507, Part 5 of the Toledo Municipal Code. This law enforces noise levels emitted from fixed machinery or equipment, or similar mechanical devices. Noises that are NOT covered by this law are residential noise, noise from pets, or loud automobiles. If you have issues with these, then contact the Toledo Police Department. Our division only handles noise relating to industrial processes.

90 dbA Sound Level

The maximum sound produced by any piece of construction equipment manufactured after March 5, 1977, within a residential area, or within 500 feet of a school or hospital is 90 dbA. See Link Zoning District Sound level Restrictions, Exemptions,Construction noise(Toledo Municipal Code 507, Anti Noise Law)

 Open Burning


Open burning is any open flame exposed to the environment, where pollutants produced from the fire are emitted directly into the surrounding air. This includes the burning of leaves, wood and trash. The pollutants released by open burning also make it more difficult to meet health-based air quality standards, especially in or near large cities. The gases released by open burning can also corrode metal siding and damage paint on buildings.  For more information regarding open buring permiting and regulations, please click the links below below.

Asbestos 2


Asbestos is a naturally occurring mineral fiber, once widely used in building materials and products for its thermal insulating properties and fire resistance.

Intact, undisturbed asbestos-containing materials generally do not pose a health risk. These materials may become hazardous and pose increased risk if they are damaged, are disturbed in some manner, or deteriorate over time and release asbestos fibers into building air. A number of building materials and products still in use today contain asbestos. Asbestos remains in use as an acoustic insulator, and in thermal insulation, fire proofing, roofing, flooring and other materials.

The regulations require that contractors do several things, such as provide a notification; conduct thorough inspections to determine the presence of asbestos; follow specific work practices; and ensure proper disposal of asbestos-containing material.


ORC 3745.11(G) - An owner or operator who is responsible for an asbestos demolition or renovation project pursuant to rules adopted under section 3704.03 of the Revised Code shall pay the fees set forth in the following schedule. Applies when thresholds are greater than or equal to: 260 linear feet; 160 square feet; or 35 cubic feet.

  • Each notification $75
  • Asbestos removal $3/unit (1 unit = any combination of linear feet or square feet equal to fifty)
  • Asbestos cleanup $4/cubic yard
