Whether the reservation of “all coal” in the Coal Lands Acts of 1909 and 1910 includes coalbed methane gas.
Holding
No. In the 1909 and 1910 Acts, “coal” meant the solid rock fuel and did not include coalbed methane gas.
Reasoning
The Court interpreted the statutory term according to its ordinary, contemporary, common meaning when Congress enacted the Acts—not according to modern scientific understanding of coal’s chemical composition. Congress addressed a practical problem in a practical way, so the relevant inquiry was what legislators and the public in 1909 and 1910 ordinarily understood “coal” to mean.
Contemporary dictionaries consistently defined coal as a solid, combustible mineral used as fuel. By contrast, they described methane, “fire-damp,” or marsh gas as a separate gas contained in or emitted from coal. This usage showed that coalbed methane was understood as distinct from coal itself, both because it was gaseous rather than solid and because it escaped from coal during mining.
The statutes’ history reinforced that ordinary meaning. Congress enacted the 1909 and 1910 Acts to preserve and manage the solid coal resource that powered industry after concerns about coal shortages and fraud in federal coal-land acquisition. Congress rejected proposed bills that would have reserved oil, natural gas, and other fuel minerals, ultimately choosing the narrower term “coal.”
At the time, coalbed methane was principally known as a dangerous waste product that caused mine explosions and had to be vented. Although there had been limited efforts to use it as fuel, Congress had no evident reason to treat it as part of the valuable solid coal resource it sought to conserve. If Congress had considered its extraction, it likely would have regarded that activity as drilling for natural gas rather than mining coal.
Later enactments confirmed that Congress knew how to reserve gas when it intended to do so. For example, a 1912 statute expressly reserved “oil and gas,” while the 1916 Stock-Raising Homestead Act reserved “all the coal and other minerals.” The specific and limited wording of the 1909 and 1910 Acts therefore could not be expanded to cover coalbed methane.
The Tribe’s argument that a coal owner must own coalbed methane in order to mine coal did not alter the ownership question. The coal owner may have a common-law right to vent or otherwise affect gas when reasonably necessary to extract coal, but a necessary right of use does not establish ownership of the gas. Split mineral estates were familiar when Congress legislated, and ordinary negotiation or adjudication could resolve conflicts between their owners.
Because the Court found that the most natural reading of “coal” excluded coalbed methane, it did not decide whether the canon favoring the sovereign in ambiguous land grants applied. That canon matters only after a genuine ambiguity remains following ordinary statutory interpretation.
