On September 24, 2018, in two separate decisions, the Sixth Circuit Court of Appeals found that coal ash wastewater that enters groundwater and eventually travels to navigable waters through the groundwater is not regulated under the Clean Water Act (“CWA,” or the “Act”).  In these decisions, the Sixth Circuit expressly disagrees with recent holdings from the Fourth and Ninth Circuits, paving the way for potential Supreme Court review.

The CWA requires a permit for discharge of pollutants into navigable waters.  33 U.S.C. §§ 1251 et seq.  At issue in both Sixth Circuit cases is whether the CWA extends to regulate indirect discharge into a navigable water, through groundwater.  Rejecting the “hydrological connection” theory, the Sixth Circuit found that groundwater is not subject to regulation under the CWA because it is not a point source.  Therefore, the discharge of pollutants into groundwater, and subsequent travel to a navigable water, also does not fall within the scope of the CWA.Continue Reading Sixth Circuit Limits Scope of CWA, Breaking with Fourth and Ninth Circuits

Reviving a federal Clean Water Act (“CWA”) lawsuit, the U.S. Court of Appeals for the Fourth Circuit held that an indirect discharge – such as a discharge to ground water – may fall within the scope of the CWA, if the indirect discharge is sufficiently connected to navigable waters to be covered under the CWA.  The decision was issued on April 12, 2018, in the case, Upstate Forever et al. v. Kinder Morgan Energy Partners LP, et al.  The facts were unusual for a citizen suit, in that the citizen group plaintiffs were targeting discharges to ground water.  Plaintiffs alleged that defendants were in violation of the CWA because defendant (or “Kinder Morgan”) discharged pollutants into navigable waters without obtaining a National Pollutant Discharge Elimination System (“NPDES”) permit.  The source of the alleged discharge is a gasoline spill: in 2014, “over 369,000 gallons of gasoline spilled from Kinder Morgan’s underground pipeline, which extends over 1100 miles through parts of the eastern United States.”  Slip Op. at 8.  According to plaintiffs, the “gasoline pollutants from the pipeline are seeping into navigable waters as defined by the CWA.”  Id.  Kinder Morgan subsequently repaired the pipeline, and has recovered at least a portion of the spilled gasoline.

On February 1, 2018, the U.S. Court of Appeals for the Ninth Circuit upheld the district court’s decision, finding that the County of Maui violated the Clean Water Act (“CWA”) when it discharged treated effluent into underground injection wells, which then allowed the effluent to seep into the Pacific Ocean.  The Ninth Circuit panel held that the wells were required to obtain National Pollutant Discharge Elimination System (“NPDES”) permit coverage because the discharge from the wells was “fairly traceable” from the discharge point (point source) to a navigable water.

The Ninth Circuit recently ruled that federal reserved water rights held by Indian tribes extend to groundwater underlying reservation lands. Determining the quantity of that groundwater, however, is reserved for another day.

In Aqua Caliente Band of Cahuilla Indians v. Coachella Valley Water District, the Ninth Circuit affirmed the district court’s declaration that the United States impliedly reserved appurtenant water sources, with “appurtenant” including groundwater, when it created the Aqua Caliente Band of Cahuilla Indians’ reservation in the Coachella Valley of California. The decision marks the first time that a federal appellate court has recognized groundwater rights as being included in federal reserved water rights.

Federal reserved rights are water rights that are appurtenant to land that has been withdrawn from the public domain by the federal government, and that are necessary to accomplish the federal purpose of the withdrawn (or “reserved”) land. In a landmark decision issued over 100 years ago, Winters v. United States, the U.S. Supreme Court held that federal reserved rights apply to Indian reservations. These rights, known as Winters rights, derive from the federal purpose of the reservation.  In the case of the Aqua Caliente Band of Cahuilla Indians (the “Tribe”), the Ninth Circuit explained that, “[w]ithout water, the underlying purpose—to establish a home and support an agrarian society—would be entirely defeated.”Continue Reading Tribes’ Federal Water Rights Include Groundwater—But How Much?
