Environmental Law columnists Michael B. Gerrard and Edward McTiernan write: Under Barack Obama, climate litigation was mostly industry and red states seeking to block regulations.

Uncertainty About Hydrologically Connected Groundwater Has Implications in New York

In their Environmental Law column, Michael B. Gerrard and Edward McTiernan write: Federal district courts are divided over whether the Clean Water Act prohibits discharges to groundwater when the subsurface receiving water is so closely connected to waters of the United States that it serves as a direct conduit to introduce pollutants to surface waters. Because the failure to have a permit for a regulated discharge can lead to significant compliance obligations, material fines and penalties and can be enforced by private citizens, this unresolved question has far-reaching consequences.

New York Environmental Legislation: 2016 in Review

Environmental Law columnists Michael B. Gerrard and Edward McTiernan write: While 2016 did not bring major environmental legislation in New York state, laws were enacted that could have significant impacts in coming years, including a law that allows plaintiffs to bring toxic tort claims in connection with newly designated Superfund sites that might otherwise be barred by existing statutes of limitations. Gov. Andrew M. Cuomo also signed laws requiring lead testing of drinking water in schools, establishing a task force to study ocean acidification, and creating a program to fund local climate change mitigation and adaptation projects.
