On April 12, 2018, the U.S. Court of Appeals for the Fourth Circuit in Upstate Forever v. Kinder Morgan Energy Partners, L.P., No 17-1640, held that the Clean Water Act (CWA) regulates point source discharges that reach “navigable waters” through groundwater with a “direct hydrologic connection” to the surface water. With this decision, the Fourth Circuit (which includes Maryland, North Carolina, South Carolina, Virginia and West Virginia) has joined the Ninth Circuit in recognizing the so-called groundwater “conduit theory” of liability under the CWA, a theory environmental groups are relying upon in several CWA citizen suits across the country. Under the groundwater “conduit theory,” separately regulated and permitted wastewater collection basins, impoundments, wells, and/or pipelines that result in groundwater contamination could be the targets for CWA liability, even though it is widely accepted that the CWA does not regulate discharges to groundwater itself. These cases have broad implications for many industries, including steelmaking, pipelines, mining, chemical manufacturing, oil and gas development, and utilities.
Background and District Court Decision
The Upstate Forever case dates back to 2016, when two environmental organizations filed a lawsuit alleging CWA violations stemming from a 2014 pipeline leak. According to the complaint, 369,000 gallons of petroleum products leaked from an underground pipeline. The plaintiffs alleged that the pipeline contents seeped into groundwater and later into two nearby creeks and their adjacent wetlands downgradient from the leak. The leak was fixed within a few days of discovery and approximately 209,000 gallons of petroleum products were recovered through remediation efforts overseen by a state environmental regulatory agency. The plaintiffs, however, alleged that a plume of petroleum contaminants continued to migrate from groundwater to surface water several years after the leak was fixed. …
