MINDING your WASTEWATER

A Brief Overview of the National Pollutant Discharge Elimination System (NPDES) Permitting Program and Why You Should Care

ater quality is crucial to the success of any distillery. Accordingly, a distillery should pay special attention to the water going into its product from start to finish. Equally important, and often ignored, is what happens to the water that does not make it into the bottle, i.e., your wastewater. Understanding the latter is necessary to ensure compliance with applicable local, state, and federal water quality standards and related discharge requirements. Below is a quick overview of the national permitting scheme under the federal Clean Water Act (CWA), the nation’s foremost law regulating the quality of surface water.
In a nutshell. Among other things, the CWA requires a person to be covered under a permit prior to the “discharge of a pollutant” from any “point source” into “navigable waters.”1 These permits are commonly known as National Pollutant Discharge Elimination System (NPDES) permits. In many states, such permits are administered by a state agency authorized to oversee the NPDES program in that state. For example, California’s NPDES program is administered through the California State Water Resources Control Board and the various Regional Water Quality Control Boards, while Kentucky’s program is administered by the Kentucky Energy and Environment Cabinet. Note that a state-run program may require broader coverage than the CWA and could further regulate discharges into state waters. A map of states authorized to administer the NPDES program is available on the U.S. Environmental Protection Agency’s (EPA) website.2 Depending on the type of discharge and the state permitting scheme, a discharger may be able to obtain coverage under a general permit, rather than applying for an individual NPDES permit specific to the discharger’s facility. Dischargers must comply with the requirements of any individual or general permit authorizing the discharge. An NPDES permit is typically valid for up to five years. 1

So, who needs a permit? As previously stated, the CWA’s permit requirement applies to anyone discharging a “pollutant” from any “point source” into “navigable waters.” “Pollutant” is broadly defined and includes chemical wastes, biological materials, sand, cellar dirt, industrial wastes, and ... heat. Yes, even heat. The CWA’s definition of “industrial user” includes establishments primarily engaged in manufacturing alcoholic liquors by distillation.3 “Point source” is also broadly defined by the CWA, but essentially is an identifiable and confined conveyance such as a pipe, channel, conduit, or container from which a pollutant is or may be discharged. As may be evident, many discharges from distilleries fall within the parameters set forth above. However, not every discharge of pollutants is subject to the CWA. Specifically, the CWA’s permit requirement is focused on discharges into “navigable waters.” The CWA defines “navigable waters” as “waters of the United States.”4 For purposes of this article, it is safe to assume that this includes oceans, coastal waters, and many rivers, streams, creeks, and lakes, among other bodies of water.5 Permits are also required for discharges that are the functional equivalent of a direct discharge from a point source into navigable waters.6 What this all means is that distilleries should consult an attorney or qualified environmental 3 “Establishments primarily engaged in manufacturing alcoholic liquors by distillation, and in manufacturing cordials and alcoholic cocktails by blending processes or by mixing liquors and other ingredients” are classified under Standard Industrial Classification (“SIC”) Code 2085, which is under the category of “Division D— Manufacturing.” U.S. Dep’t of Labor, Description for 2085: Distilled and Blended Liquors, https://www.osha.gov/sic-manual/2085 (last visited Jan. 20, 2022); see 33 U.S.C. § 1362(18). 4

Most recently, the EPA and Army Corps of Engineers issued a proposed rule updating the definition of waters of the United States. Revised Definition of “Waters of the United States”, 86 Fed.
