 The Marcellus Shale Law (House Bill 1950) also contained a provision that allows doctors in Pennsylvania access to the list of chemicals in hydraulic fracturing fluid in emergency situations only, but forbids them from discussing this information with their patients.The information can only be used for emergency medical treatment, and the doctor must immediately verbally agree to keep the information confidential and later sign a document to that effect.The bill also reduced the legal responsibility of vendors, service providers, and operators regarding the identity and impact of contents of the hydraulic fracturing fluid they use.
