I. Purpose and History of CWA

Legislation
33 U.S.C. § 1251(a) – The CWA is intended to “maintain the chemical, physical, and biological integrity of the Nation’s waters.”

Cases

  • EPA v. National Crushed Stone Association, 449 U.S. 64 (1980) – Discussion of statutory framework of the CWA.
  • Texas Oil and Gas Assoc. v. EPA, 161 F.3d 923 (5th Cir. 1998) – Congress enacted the CWA and declared a national goal that the discharge of pollutants into the navigable waters be eliminated by 1985 (33 U.S.C. § 1251(a)(1)). It was designed to achieve this goal through a system of effluent limitations guidelines and National Pollutant Discharge Elimination System permits that set technology-based discharge limits for all categories and subcategories of water pollution point sources.
  • EPA v. California, 426 U.S. 200 (1976) (superceded by statute)– Good summary of the history of the Act.
  • Dubois v. U.S.D.A., 102 F.3d 1273 – The CWA “incorporated a broad systemic view of the goal of maintaining and improving water quality.” In contrast to NEPA’s focus on process, the CWA is substantive, focusing upon the “integrity of the Nation’s Waters, not the permit process.”

Congressional History and Reports

  • H.Rep. No 92-911, 92d Cong. 2d Sess. 76-77 (1972) – Subsection (a) of section 101 declares the objective of this legislation to be the restoration and maintenance of the chemical, physical, and biological integrity of the Nation’s waters. The word “integrity” as used is intended to convey a concept that refers to a condition in which the natural structure and function of the ecosystem is maintained.

Regulations
40 C.F.R. § 122.2 – “Waters of the United States or water of the U.S. means:

  1. All waters which are currently used, were used in the past, or may be susceptible to use in interstate or foreign commerce, including all waters which are subject to the ebb and flow of the tide;
  2. All interstate waters, including interstate "wetlands;"
  3. All other waters such as intrastate lakes, rivers, streams (including intermittent streams), mudflats, sandflats, "wetlands," sloughs, prairie potholes, wet meadows, playa lakes, or natural ponds the use, degradation, or destruction of which would affect or could affect interstate or foreign commerce including any such waters:
    1. Which are or could be used by interstate or foreign travelers for recreational or other purposes;
    2. From which fish or shellfish are or could be taken and sold in interstate or foreign commerce; or
    3. Which are used or could be used for industrial purposes by industries in interstate commerce;

  5. (e) Tributaries of waters identified in paragraphs (a) through (d) of this definition;
    (f) The territorial sea; and
  6. (g) ‘Wetlands’ adjacent to waters (other than waters that are themselves wetlands) identified in paragraphs (a) through (f) of this definition.”

53 Fed. Reg. 20765 (1988) – Preamble to EPA 404 regulations states that “it should be noted that we generally do not consider the following water to be ‘Waters of the United States’ [list omitted], however we reserve the right on a case-by-base basis to determine that a particular water body within these categories is water of the United States.”

Cases

  • International Paper Co. v. Ouellette, 479 U.S. 481 (1987) – Navigable waters has been construed expansively to cover waters that are not navigable in the traditional sense.
  • United States v. Riverside Bayview Homes, 474 U.S. 121 (1985) – Wetland adjacent to a navigable waterway is part of the waters of the U.S.
  • United States v. TGR Corp., 171 F.3d 762 (2nd Cir. 1999) – Held that a brook into which a slurry was discharged is waters of the U.S. The court rejected defendant’s argument that the brook is a “municipal storm sewer” and therefore not waters of the U.S. because testimony at trial showed that the brook was not “owned or operated” by a public body.]
  • United States v. Edison, 108 F.3d 1336 (11th Cir. 1997) – Held that it is “well established that Congress intended to regulate the discharge of pollutants into all waters that may eventually lead to waters affecting interstate commerce.”
  • United States v. Wilson, 133 F.3d 251 (4th Cir. 1997) – The court held that the Corps definition of wetlands which forbade activities that “could affect” interstate commerce, was invalid as it exceeded authority under the Commerce Clause.
  • Quivira Mining Co. v. EPA, 765 F.2d 126 (10th Cir. 1985) – Non-navigable creeks and “arroys” affect interstate commerce because during times of “intense rainfall” there could be a surface connection between these waterways and navigable streams.
  • Treacy v. Newdunn Assocs., 344 F.3d 407 (4th Cir. 2003) – Holding that COE jurisdiction under the CWA applies to any branch of a tributary system which eventually flows into a navigable body of water.
  • United States v. Deaton, 332 F.3d 698 (4th Cir. 2003) – Finding CWA jurisdiction over wetland adjacent to a roadside ditch that eventually connects to navigable-in-fact water 25 miles away. Cert. denied, 158 L.Ed.2d 466 (2004).
  • United States v. Rapanos, 339 F.3d 447 (6th Cir. 2003) – Finding CWA jurisdiction over wetlands 20 miles from navigable-in-fact waters. Cert. denied, 158 L.Ed.2d 467 (2004).

Cases

  • EPA v. California, 426 U.S. 200 (1976) – “Section 301(a) simply makes it ‘unlawful’ for ‘any person’ not to have the required permit. That Federal agencies, departments, and instrumentalities are not ‘persons’ within the meaning of section 301(a) does not mean that federal dischargers are not required to secure NPDES permits. A Federal discharger without a permit is no less out of compliance … than a nonfederal discharger; the Federal discharge is, however, not ‘unlawful’.”

IV. “Pollutant” (§ 502(6))

Legislation
33 U.S.C. § 1362 (6) – “pollutant” means dredged spoil, solid waste, incinerator residue, sewage, garbage, sewage sludge, munitions, chemical wastes, biological materials, radioactive materials, heat wrecked or discarded equipment, rock, sand, cellar dirt and industrial, municipal, and agricultural waste discharged into water.

V. Federal Facilities (§ 313)

Legislation
33 U.S.C. § 1323 – Federal facilities provisions.

Cases

  • EPA v. California, 426 U.S. 200 (1976) – “Section 301(a) simply makes it ‘unlawful’ for ‘any person’ not to have the required permit. That federal agencies, departments, and instrumentalities are not ‘persons’ within the meaning of section 301(a) and the Amendments … does not mean either that federal dischargers are not required to secure NPDES permits, or that their obligation to secure an NPDES permit derives from a different provision of the Amendments. A federal discharger without a permit is no less out of compliance … than a nonfederal discharger; the federal discharge is however not ‘unlawful’.”
  • Marble Mountain Audubon Society v. Rice, 914 F.2d 179 (9th Cir. 1990) – The CWA requires the Forest Service to comply with all State water quality requirements.
  • National Wildlife Federation v. Bureau of Land Management, No. EA A2-026-92-24 (Dept. of Interior, Interior Board of Land Appeals Nov. 18, 1996) – Administrative stay of proposed grazing based on potential impacts on “outstanding natural resource water.”

VII. State Certification of Federal Permits (401 Certificate)

Legislation
33 U.S.C. § 1341(a)(1) – “Any applicant for a Federal license or permit to conduct any activity including, but not limited to, the construction or operation of facilities, which may result in any discharge into navigable waters” shall obtain a certification for the State where the discharge originated “that any such discharges will comply with the applicable provisions of sections 301, 303, and 307” of the CWA.

33 U.S.C. § 1341(d) – State certifications shall “set forth any effluent limitations and other limitations, and monitoring requirements necessary to assure that any applicant for a Federal license or permit will comply with any applicable effluent limitations and other limitations, under section 1311 or 1312 of this title, standard of performance under section 1316 of this title, or prohibition, effluent standard, or pretreatment standard under section 1317 of this title, and with any other appropriate requirements of State law set forth in such certification ….”

Washington State Dept of Ecology, 511 U.S. 700 (1994) – Section 401 requires the State to assure compliance with state water quality standards in light of the permitted “activity” not just the “discharger”; thus Washington’s minimum stream flow requirement is a permissible condition of a section 401 certification.
  • Citizens Interested in Bull Run v. R.L.K. & Co., 1998 U.S. App. LEXIS 3926 (9th Cir. 1998) – Dismissal of suit against ski area for discharge of road salt upheld; held that salt in snow that runs off during spring is not an “activity” within the meaning of 401(a), so FS permit need not be certified.
  • Oregon Natural Desert Ass’n v. Dombeck, 151 F.3d 945 (9th Cir. 1998) – Held that 401 certification does not apply to nonpoint source pollutants, such as manure from grazing on public lands; distinguished dam cases (Consumers Power et al.) on grounds that dams are point sources but they don’t discharge pollutants.
  • United States v. Marathon Dev. Corp., 867 F.2d 96 (1st Cir. 1989) – If state determines that discharges from certain category of activity will not meet state water quality requirements, the Federal government is prohibited from authorizing the activity by Federal permit.
