Allows conventional hydraulic fracturing in sandstone for the production of tight gas, a traditional technique used in natural gas fields, to continue despite fracking ban, but under more stringent conditions for permit application: An environmental impact assessment is required. Only non-hazardous or low hazardous fracturing fluids are allowed. In the case of damages due to seismic events, a reversal of evidence is provided: in case of doubt, the companies will have to prove that damage is not caused by hydraulic fracturing activities.
