In February 2011, hundreds of physicians, scientists, and organizations representing thousands of health professionals sent a letter to DOH Commissioner Dr. Nirav R. Shah detailing the risks to human health from various stages of the gas development process and urging co-lead status for the DOH in the SGEIS process. /http://concernedhealthny.org/letters-to-governor-cuomo/

On May 26, 2011, the NYS Assembly Environmental Conservation and Health Committees jointly held a public hearing on the connection between natural gas development and public health. Testimony by medical professionals and scientists indicated the need for thorough public health investigation before permits for high volume hydraulic fracturing and horizontal drilling are issued. see Assemblyman Gottfried’s site, scroll to fracking update http://assembly.state.ny.us/member_files/075/20111221/  and see Assembly testimony here http://www.gasdrillingtechnotes.org/index.html

Regulations and a Revised Draft SGEIS on the Oil, Gas and Solution Mining Regulatory Program (September 2011) Well Permit Issuance for Horizontal Drilling and High-Volume Hydraulic Fracturing in the Marcellus Shale and Other Low-Permeability Gas Reservoirs, also known as the rdSGEIS, were issued at the same time, and public comment on both the regulations and the rdSGEIS began in November 2011.  Altogether over the two comment periods, 80,000 comments were received by the DEC, and many focused on the lack of attention to health and environmental impacts of gas development, including air and water pollution and soil contamination, which are established pathways of exposure.   Other topics not covered, or covered inadequately included community stressors, psychosocial impacts, worker safety and radiological exposure.  Many health professionals commented on the need for a comprehensive Health Impact Assessment to assess the range and degree of potential health impacts.

There is a growing body of evidence on health impacts from industrial gas development. In Texas, Wyoming, Louisiana, North Dakota, Pennsylvania, and other states, cases have been documented of worsening health among residents living in proximity to gas wells and infrastructure such as compressor stations and waste pits. Symptoms are wide-ranging, but are typical for exposure to the toxic chemicals and air and water pollutants used in oil and gas development and can often be traced to the onset of such operations.
