Issue Presented: Does Mr. Villegas’s conduct amount to a “discharge” under the Clean Water
Act? Is he, a human being, a “point source” within the meaning of the act?
The Clean Water Act makes unlawful “the discharge of any pollutant by any person
. . . .” 33 U.S.C. Section 1311(a). “Pollutant” is defined, in part, as “biological materials . . .
discharged into water.” 33 U.S.C. Section 1362(6). “Discharge,” in turn, is “any addition of any
The issue before the court in U.S. v. Plaza Health Laboratories, Inc., 3 F.3d 643 (2nd Cir.
1993), was whether Mr. Villegas’s conduct constituted a “discharge” under the Clean Water Act.
To determine the scope of the Clean Water Act’s definition of “point source,” the court
first considered the language and structure of the act itself. The court explained:
Human beings are not among the enumerated items that may be a “point
source.” Although by its terms the definition of “point source” is
nonexclusive, the words used to define the term and the examples given
(“pipe, ditch, channel, tunnel, conduit, well, discrete fissure,” etc.) evoke
images of physical structures and instrumentalities that systematically act
as a means of conveying pollutants from an industrial source to navigable
waterways.
