Regulations
Name 3 of the 6 “criteria” air pollutants specifically regulated by the Clean Air Act.
What are sulfur dioxide, nitrogen dioxide, carbon monoxide, particulate matter, ozone, and lead?
This machine removes harmful particulates or gases from industrial exhaust, commonly using liquids or dry materials
What is a scrubber?
Limestone is mixed with this material before being burned in a boiler.
What is crushed coal?
This is the byproduct of using scrubbers, it can be used to make drywall.
What is gypsum?
Traveling on a bike, bus or just by walking is more energy efficient than driving in this vehicle.
What is a car?
This act allowed the EPA to set acceptable levels for air pollutants.
What is the Clean Air Act?
This machine captures hydrocarbon VOCs released from gasoline fumes during refueling
What is a vapor recovery nozzle?
Limestone can be used to make gypsum wallboards or sheetrock for what places?
What are homes?
Sulfur oxide needs a mixture of limestone and water to capture pollutants while scrubbers that need liquid can simply use water.
What is a wet scrubber?
These types of energy harness sun, wind and water.
What is renewable energy?
These standards require all U.S. vehicles to meet certain average fuel standards.
What are CAFE (Corporate Average Fuel Economy) standards?
This machine removes particulate matter (PM) from industrial exhaust gas
What is a baghouse filter?
During fluidized bed combustion, fluidizing jets of air are pumped into this machine.
What is a combustion bed?
A coal power plant installs scrubbers and uses limestone to capture sulfur dioxide before it enters the atmosphere, preventing this environmental problem.
What is acid rain?
Eating these types of foods help conserve more energy.
What are plants?
These are special marketable rights that can be sold to companies that release more than acceptable pollution levels.
What are pollution credits?
This machine lies in cars and converts dangerous pollutants into less harmful vapors such as water, carbon dioxide and oxygen.
What is a catalytic converter?
Fluidized bed combustion reduces the emission of this pollutant?
What is NOX?
This type of scrubber does not collect as many pollutants as wet scrubbers.
What is a dry scrubber?
Habits such as your diet, how you travel and how you use your energy all contribute to this.
What is your carbon footprint?
Due to the need to protect the new catalytic converters, this action was taken in 1973 to reduce a pollutant drastically.
What is the phase out of lead in gasoline?
This machine gives pollutants negative charges, ultimately trapping them when they stick to a positively charged collection plate.
What is an electrostatic precipitator?
Crushing limestone reduces the emission of SO2 in what types of buildings?
What are coal power plants?
A factory installs electrostatic precipitators and baghouse filters to remove particles before emissions leave the smokestack. These devices are designed to remove this kind of pollutant.
What is particulate matter (PM)?
In order to conserve energy, you can replace your fridge, washing machine, and other machines with these new devices.
What are smart appliances?
