Fracking. Are you for it or against it?

4. Against - Exemptions for hydraulic fracturing under United States federal law

Fracking would be non-existent or extremely rare if the fracking industry did not have specific exemptions from environmental laws.

------------------------------------------------------

There are many exemptions for hydraulic fracturing under United States federal law: the oil and gas industries are exempt or excluded from certain sections of a number of the major federal environmental laws. These laws range from protecting clean water and air, to preventing the release of toxic substances and chemicals into the environment: the Clean Air Act, Clean Water Act, Safe Drinking Water Act, National Environmental Policy Act, Resource Conservation and Recovery Act, Emergency Planning and Community Right-to-Know Act, and the Comprehensive Environmental Response, Compensation, and Liability Act, commonly known as Superfund.

Hydraulic fracturing, also known as fracking, is a process used to extract oil and natural gas. The process to extract oil and natural gas begins with thousands of gallons of water, mixed with a slurry of chemicals, some of which are undisclosed. This liquid mixture is then forced into well casings under high pressure, and then is horizontally injected into bedrock to create cracks or fissures. The forced change in geologic structure allows gas molecules to escape, therefore allowing the natural gas to be harvested.

Hydraulic fracturing has changed the energy scene as a result of many technological advances. Fracking uses both historically-known vertical and horizontal drilling techniques which are used in tandem to extract oil and gas. This process can occur at depths over 10,000 feet deep.

The primary product of hydraulic fracturing is natural gas which consists mostly of methane.
