• Definition

• History

• Reactivity vs Mass Based Regulations

• Current Regulations!!!

Definition

• Volatile Organic Compound:

• The United States Environmental Protection Agency(EPA) defines a VOC as any organic compound that participates in a photoreaction.

Major Air Pollution Sources

Motor Vehicles, Consumer Products,Stationary Sources, etc.

Volatile Organic Compounds (VOCs)

Ground-level Ozone, Particulate Matter (PM10/2.5)

(Smog)

Oxides of Nitrogen (NOx)

Why are VOC’s regulated?Smog Formation

History of VOC Regulation

• Beginning with California

MOST ACTIVE

California Air Resources Board

CARB

What Are Consumer

Products?

Consumer Products:

• Chemically formulated

• Used by household and

institutional (I&I) consumers

• Includes household, home and

garden, aerosol paint,

personal care, automotive

specialty (care) products, etc.

VOC reductions

• Without regulation the emissions would have been over 440 TPD

• Currently the emissions are 240 TPD

• That is a 200 TPD reduction

Ozone Depleters Banned

• HCFC – 22

• HCFC – 141B

• Trichloroethane

• All Gone!!!!!!

Conclusion

• VOC Regulations Scientifically Based

• Consumer Products have become Greener!!!

• More to do!!!
