With two weeks of the legislative session remaining, advocates are making a last-minute push to ban hydraulic-fracturing waste from coming into New York from neighboring states.

Despite the Cuomo administration's December 2014 ban on fracking—a controversial practice in which liquid is injected at high pressure to release gas from rock formations—New York has received more than 600,000 tons of oil and gas waste associated with the practice from Pennsylvania, according to Liz Moran of Environmental Advocates of New York.

Because New York “doesn't have a method that is publicly available to track oil and gas waste coming from Pennsylvania” the group uses a database from Pennsylvania's Department of Environmental Protection to track how much waste is coming into New York, Moran said.
