UNITED STATES -- Members of Congress wrote a letter to President Obama, voicing concerns about the impact hydrofracking could have on air quality.

The letter calls for stronger protections from air pollution by implementing the Environmental Protection Agency's New Source Performance Standards.

Congressman Maurice Hinchey is among those who signed the letter. He says hydrofracking releases a significant amount of pollutants, including Volatile Organic Compounds, hazardous air pollutants and methane, which he says can lead to health problems.

The letter says the New Source Performance Standards would significantly reduce air pollution caused by hydrofracking.

This comes as the EPA is set to present its final rules regarding air quality for the oil and natural gas industry.

The agency's deadline to release air quality standards is Tuesday.
