EPA Air Quality Control

According to the EPA, Environmental Protection Agency, State Implementation Plans (SIP's) are enforced for every state in order to designate areas of the United States that are attained (meeting) or non-attained (not meeting) the standard requirements specified. SIP's show the EPA which states' air quality programs has the correct components in order to meet the NAAQS (National Ambient Air Quality Standards) and are also designed to prevent air quality deterioration for areas within attainment and to reduce the common pollutants in non-attainment areas to meet the required numbers. The Clean Air Act (CAA), established in the 1970's, requires each individual state to establish their own local air quality control agencies monitored by the EPA. This act was put in place to protect the public's well-being caused by the numerous pollutants within the air.

This image gives a few facts and statistics about the Clean Air Act that was established in 1970. It describes how industrial production is a major contributor to greenhouse gases, how much air humans need on a daily basis, and the number of people at risk of air pollutants.

The NAAQS has six "criteria" pollutants along with a set of standards for each one. According to the EPA's website, these six pollutants include: ozone, particulate matter, carbon monoxide, nitrogen oxides, sulfur dioxide, and lead. The EPA describes these pollutants as "criteria" pollutants because they regulate the developing human and environmental health-based criteria that regulates acceptable levels. Human health limits are called primary standards, while environmental and property damage are called secondary standards. Each pollutant is monitored by the EPA with two different kinds of air pollutant trends. The first is air concentration based on concentrations of the pollutant in ambient (outside) air recorded at a various locations throughout the United States, and the second is emissions based from estimates of engineering information from the total amount of tons of the specific pollutant that is released into the air every year.

This image describes the primary and secondary standards for each of the six criteria air pollutants. This is the NAAQS required levels and averaging time for each pollutant and also describes the required amount for each to be considered an attainment area.

This chart indicates which levels of the criteria pollutants are in full attainment in Ohio and which levels are in non-attainment, along with a map of where each non-attainment area is located throughout the state of Ohio. 

In the state of Ohio, the EPA classifieds this state as "full attainment"for most of the state, besides a few areas. Carbon monoxide levels in Ohio have the appropriate levels of 9 ppm per eight hours and 35 ppm for one hour. Lead levels in the state of Ohio have full attainment at 1.5 micro-grams per cubic meter of air for a quarterly average, but the 0.15 micro-grams per cubic meter of air for a rolling three month period have non-attainment areas in Cleveland, Logan County, and Fulton County. For Nitrogen Dioxide, it has full attainment levels for 0.053 ppm annually, and 100 ppb for one hour. Levels of particulate matter at PM10 for 150 micro-grams per cubic meter of air for a 24 hour period is at full attainment and the particulate matter at PM2.5 for 15.0 and 35 micro-grams per cubic meter of air, but the particulate matter at PM 2.5 for 12 micro-grams per cubic meter has non-attainment areas located near Cleveland, OH for the counties of Cuyahoga, OH and Lorain, OH. Ozone levels in Ohio are at full attainment for 0.08 ppm per eight hours and 0.12 ppm per one hour, while ozone levels at 0.075 ppm per eight hours has a non-attainment area in Ohio located in Cleveland/Akron/Lorain (includes the counties of Lorain, Medina, Cuyahoga, Summit, Portage, Geauga, Lake, and Ashtabula), Columbus (includes the counties of Madison, Franklin, Delaware, Knox, Licking, and Fairfield) and Cincinnati area (includes the countries of Butler, Warren, Clinton, Hamilton, Clermont, Campbell, Dearborn, Boone, and Kenton). Sulfur dioxide levels at 75 ppb at one hour have non-attainment areas in Ohio including the counties of Campbell, Clermont, Morgan, Washington, Jefferson, and Lake.

This image shows the air pollution across the downtown area of Cleveland, OH. This is known to occur more prominent when temperature inversions trap the air pollution from mobile sources that are closest to the ground.

This image shows the Gavin power plant located in Chestire, OH that is proposed to service about 10,000 homes near Athens, OH. This plant is considered the largest power plant in Ohio that runs on coal power and is owned and operated by AEP (American Electric Power). 

The air quality in Ohio is regulated by the NAAQS's six criteria pollutants, but is also monitored by regulatory emissions reports every 15th of April. These reports identify the emission quality and quantity of the previous year. Also, Ohio EPA is regulated by obtaining air pollution control permits to monitor and estimate exactly how much of the criteria pollutants are being emitted into the each year.
