Clean Water Act of 1972Amended Federal Water Pollution Control Act of 1948Passed by congress to protect waters of the U.S. Includes several sections:Section 301: requires permits for discharges Section 319: creates non-point source management
program Section 402: authorizes national pollution discharges
elimination system permit programSection 404: establishes program to regulate discharge
of material into waters of the U.S.

Section 404 Administered jointly by the Corps of Engineers and
Environmental Protection Agency Regulation based on two necessary criteria: A water of the U.S. is present There is a discharge of dredged or fill material into that
waters of the U.S. which does not qualify for an exemption
Many regulatory decisions and criteria are subject to district interpretation—high degree of variability throughout the U.S.

Jurisdictional Extent of Section 404Pre-2001: migratory bird rule
Waters of the U.S. are defined in U.S. Supreme Court cases (Rapanos v. U.S. and Solid Waste Agency of Northern Cook County v. U.S.)
Supreme Court decisions interpreted by USACE and EPA in 2008 Memorandum

Current Definition of Waters of the U.S.—Agency GuidanceThe agencies will assert jurisdiction over:Traditional Navigable Waters (TNW) And adjacent wetlands
Non-navigable tributaries to TNW that are relatively permanent waters (RPW) And adjacent wetlands
![Page 7: Noah Greenberg, Wright Water Engineers Benjamin Guillon, WRA › assets › (b)-darca_wetlands2.pdf · Microsoft PowerPoint - DARCA_wetlands2.pptx Author: skribs Created Date: 3/11/2013](https://reader033.vdocuments.net/reader033/viewer/2022060314/5f0b87327e708231d430f5ea/html5/thumbnails/7.jpg)
Wetlands and WatersWetlands are areas with: Hydric soils Hydrophytic vegetation community Wetland hydrology
**As identified using USACE Methodology**Waters include: Rivers, streams, creeks, canals, ditches,
washes Harbors, lakes, ponds, reservoirs
**Delineated based on presence of ordinary high water mark

Current Definition of Waters of the U.S.—Agency Guidance
The agencies will decide jurisdiction over the following using “fact-specific analysis” of significant nexus:Non-navigable tributaries that are not RPWsAnd adjacent wetlandsWetlands that are adjacent to, but not abutting RPW tributaries to TNWs

Current Definition of Waters of the U.S.—Agency Guidance
The agencies will generally not assert jurisdiction over:Swales or erosional features with low volume,
infrequent, or short duration flow
Ditches excavated wholly in and draining only uplands that do not carry relatively permanent flow

Current Definition of Waters of the U.S.—Problematic Areas
Irrigated farmland that meets regulatory definition for wetlandsWater rights conveyance ditchesConstructed reservoirs and ponds
Water features that would not exist without continued human intervention
![Page 14: Noah Greenberg, Wright Water Engineers Benjamin Guillon, WRA › assets › (b)-darca_wetlands2.pdf · Microsoft PowerPoint - DARCA_wetlands2.pptx Author: skribs Created Date: 3/11/2013](https://reader033.vdocuments.net/reader033/viewer/2022060314/5f0b87327e708231d430f5ea/html5/thumbnails/14.jpg)
Irrigated Farmland
Regulatory guidance identifies that wetlands dependent on continued irrigation for wetland hydrology should not be considered jurisdictionalCorps determination process typically includes multi-
year groundwater study in absence of irrigationCosts to land owner to obtain this determination: Groundwater monitoring wells Consulting fees Loss of crops during dry-up period
No guarantee that USACE will determine that all/portion of irrigated wetlands are irrigation dependent
![Page 15: Noah Greenberg, Wright Water Engineers Benjamin Guillon, WRA › assets › (b)-darca_wetlands2.pdf · Microsoft PowerPoint - DARCA_wetlands2.pptx Author: skribs Created Date: 3/11/2013](https://reader033.vdocuments.net/reader033/viewer/2022060314/5f0b87327e708231d430f5ea/html5/thumbnails/15.jpg)
Water Rights Conveyance Ditches
Considered jurisdictional if:Relatively permanent flow (typically 90 days of continuous flow)Downstream surface connection to water of the U.S.
Based on typical length of irrigation season in Colorado and common return of tailwater to rivers, many ditches are considered jurisdictional waters of the U.S.
![Page 16: Noah Greenberg, Wright Water Engineers Benjamin Guillon, WRA › assets › (b)-darca_wetlands2.pdf · Microsoft PowerPoint - DARCA_wetlands2.pptx Author: skribs Created Date: 3/11/2013](https://reader033.vdocuments.net/reader033/viewer/2022060314/5f0b87327e708231d430f5ea/html5/thumbnails/16.jpg)
Constructed Reservoirs and Ponds
Considered jurisdictional if:Downgradient surface water
connection to a water of the U.S.
Many reservoirs and ponds develop wetland areas along the fringe of the normal operating water level. These areas can be problematic for enlargement projects.

Exempt Activities—Section 404(f)Normal farming activitiesPart of established and ongoing activity
Irrigation ditch construction and maintenanceWork completed by agricultural owner (not M&I) If mutual ditch company, at least 50 percent of
water conveyed in ditch must be used for agricultural purposes
Drainage ditch maintenanceMinor reshaping/repair/replacement allowedDitch must be functioning or recently functioning
to qualify
![Page 19: Noah Greenberg, Wright Water Engineers Benjamin Guillon, WRA › assets › (b)-darca_wetlands2.pdf · Microsoft PowerPoint - DARCA_wetlands2.pptx Author: skribs Created Date: 3/11/2013](https://reader033.vdocuments.net/reader033/viewer/2022060314/5f0b87327e708231d430f5ea/html5/thumbnails/19.jpg)
Exempt Activities—Section 404(f)Exemptions are subject to the recapture
provision:Part I: Is there a conversion of water of the
U.S. for purpose of new use?Part II: Is there an impairment of
circulation of waters of the U.S. or reduction in the reach of water of the U.S.?
If Part I and II are answered with “yes”, the project does not qualify for an exemption

Nationwide General PermitsUSACE issues Nationwide Permits to
provide rapid authorization for variety of projects with no more than minimal impactsProjects may require pre-construction
notification, or may be authorized without coordination with the USACESome projects may require
restoration and/or mitigation if impacts to waters of the U.S. exceed 0.1 acre

Individual Permits Projects which impact more than ½ acre
of wetland or other water of the U.S. typically require an Individual Permit Permit Application Process Includes: Establishment of need for project Alternatives assessment Conformance to NEPA Public/interagency comment period
Individual Permits can require more than a year of review by government agencies, with no guarantee that a permit will be issued.
