DRAFT DECISION DOCUMENT 

NATIONWIDE PERMIT 10

This document discusses the factors considered by the Corps of Engineers (Corps) during 

the issuance process for this Nationwide Permit (NWP). This document contains: (1) the 

public interest review required by Corps regulations at 33 CFR 320.4(a)(1) and (2); and (2) 

a discussion of the environmental considerations necessary to comply with the National 

Environmental Policy Act. This evaluation of the NWP includes a discussion of compliance 

with applicable laws, consideration of public comments, an alternatives analysis, and a 

general assessment of individual and cumulative impacts, including the general potential 

effects on each of the public interest factors specified at 33 CFR 320.4(a). 

1.0 Text of the Nationwide Permit 

Mooring Buoys. Non-commercial, single-boat, mooring buoys. (Section 10) 

1.1 Requirements 

General conditions of the NWPs are in the Federal Register notice announcing the issuance 

of this NWP. Pre-construction notification requirements, additional conditions, limitations, 

and restrictions are in 33 CFR part 330. 

1.2 Statutory Authority 

 Section 10 of the Rivers and Harbors Act of 1899 (33 U.S.C. 403) 

1.3 Compliance with Related Laws (33 CFR 320.3) 

1.3.1 General 

NWPs are a type of general permit designed to authorize certain activities that have minimal 

adverse effects on the aquatic environment and generally comply with the related laws cited 

in 33 CFR 320.3. Activities that result in more than minimal adverse effects on the aquatic 

environment, individually or cumulatively, cannot be authorized by NWPs. Individual 

review of each activity authorized by an NWP will not normally be performed, except when 

preconstruction notification to the Corps is required or when an applicant requests 

verification that an activity complies with an NWP. Potential adverse impacts and 

compliance with the laws cited in 33 CFR 320.3 are controlled by the terms and conditions 

of each NWP, regional and case-specific conditions, and the review process that is 

undertaken prior to the issuance of NWPs. 

The evaluation of this NWP, and related documentation, considers compliance with each of 

the following laws, where applicable: Sections 401, 402, and 404 of the Clean Water Act; 

Section 307(c) of the Coastal Zone Management Act of 1972, as amended; Section 302 of 

the Marine Protection, Research and Sanctuaries Act of 1972, as amended; the National 
2 

Environmental Policy Act of 1969; the Fish and Wildlife Act of 1956; the Migratory Marine 

Game-Fish Act; the Fish and Wildlife Coordination Act, the Federal Power Act of 1920, as 

amended; the National Historic Preservation Act of 1966; the Interstate Land Sales Full 

Disclosure Act; the Endangered Species Act; the Deepwater Port Act of 1974; the Marine 

Mammal Protection Act of 1972; Section 7(a) of the Wild and Scenic Rivers Act; the Ocean 

Thermal Energy Act of 1980; the National Fishing Enhancement Act of 1984; the 

Magnuson-Stevens Fishery and Conservation and Management Act, the Bald and Golden 

Eagle Protection Act; and the Migratory Bird Treaty Act. In addition, compliance of the 

NWP with other Federal requirements, such as Executive Orders and Federal regulations 

addressing issues such as floodplains, essential fish habitat, and critical resource waters is 

considered. 

1.3.2 Terms and Conditions 

Many NWPs have notification requirements that trigger case-by-case review of certain 

activities. Two NWP general conditions require case-by-case review of all activities that 

may adversely affect Federally-listed endangered or threatened species or historic properties 

(i.e., general conditions 19 and 20). General condition 17 restricts the use of NWPs for 

activities that are located in Federally-designated wild and scenic rivers. None of the NWPs 

authorize artificial reefs. General condition 27 prohibits the use of an NWP with other 

NWPs, except when the acreage loss of waters of the United States does not exceed the 

highest specified acreage limit of the NWPs used to authorize the single and complete 

project. 

In some cases, activities authorized by an NWP may require other federal, state, or local 

authorizations. Examples of such cases include, but are not limited to: activities that are in 

marine sanctuaries or affect marine sanctuaries or marine mammals; the ownership, 

construction, location, and operation of ocean thermal conversion facilities or deep water 

ports beyond the territorial seas; activities that result in discharges of dredged or fill material 

into waters of the United States and require Clean Water Act Section 401 water quality 

certification; or activities in a state operating under a coastal zone management program 

approved by the Secretary of Commerce under the Coastal Zone Management Act. In such 

cases, a provision of the NWPs states that an NWP does not obviate the need to obtain other 

authorizations required by law. [33 CFR 330.4(b)(2)] 

Additional safeguards include provisions that allow the Chief of Engineers, division 

engineers, and/or district engineers to: assert discretionary authority and require an 

individual permit for a specific activity; modify NWPs for specific activities by adding 

special conditions on a case-by-case basis; add conditions on a regional or nationwide basis 

to certain NWPs; or take action to suspend or revoke an NWP or NWP authorization for 

activities within a region or state. Regional conditions are imposed to protect important 

regional concerns and resources. [33 CFR 330.4(e) and 330.5] 
3 

1.3.3 Review Process 

The analyses in this document and the coordination that was undertaken prior to the 

issuance of the NWP fulfill the requirements of the National Environmental Policy Act 

(NEPA), the Fish and Wildlife Coordination Act, and other acts promulgated to protect the 

quality of the environment. 

All NWPs that authorize activities which may result in discharges of dredged or fill material 

into waters of the United States require water quality certification. NWPs that authorize 

activities within, or affecting land or water uses within a state that has a Federally-approved 

coastal zone management program, must also be certified as consistent with the state’s 

program. The procedures to ensure that the NWPs comply with these laws are described in 

33 CFR 330.4(c) and (d), respectively. 

1.4 Public Comment and Response 

For a summary of the public comments received in response to the February 16, 2011, 

Federal Register notice, refer to the preamble in the Federal Register notice announcing the 

reissuance of this NWP. The substantive comments received in response to the February 16, 

2011, Federal Register notice were used to improve the NWP by changing NWP terms and 

limits, notification requirements, and/or NWP general conditions, as necessary. 

The Corps did not propose any changes to this NWP. 

[This section to be completed for the final NWP.] 

2.0 Alternatives 

This evaluation includes an analysis of alternatives based on the requirements of NEPA. 

The alternatives discussed below are based on an analysis of the potential environmental 

impacts and impacts to the Corps, Federal and state resource agencies, general public, and 

prospective permittees. 

2.1 No Action Alternative (No Nationwide Permit) 

The no action alternative would not achieve one of the goals of the Corps Nationwide 

Permit Program, which is to reduce the regulatory burden on applicants for activities that 

result in minimal adverse effects on the aquatic environment, individually or cumulatively. 

The no action alternative would also reduce the Corps ability to pursue the current level of 

review for other activities that have greater adverse effects on the aquatic environment, 

including activities that require individual permits as a result of the Corps exercising its 

discretionary authority under the NWP program. The no action alternative would also 

reduce the Corps ability to conduct compliance actions. 

If this NWP is not available, substantial additional resources would be required for the 

Corps to evaluate these minor activities through the individual permit process, and for the 
4 

public and Federal, Tribal, and state resource agencies to review and comment on the large 

number of public notices for these activities. In a considerable majority of cases, when the 

Corps publishes public notices for proposed activities that result in minimal adverse effects 

on the aquatic environment, the Corps typically does not receive responses to these public 

notices from either the public or Federal, Tribal, and state resource agencies. Another 

important benefit of the NWP program that would not be achieved through the no action 

alternative is the incentive for project proponents to design their projects so that those 

activities meet the terms and conditions of an NWP. The Corps believes the NWPs have 

significantly reduced adverse effects to the aquatic environment because most applicants 

modify their projects to comply with the NWPs and avoid the delays and costs typically 

associated with the individual permit process. 

In the absence of this NWP, Department of the Army (DA) authorization in the form of 

another general permit (i.e., regional or programmatic general permits, where available) or 

individual permits would be required. Corps district offices may develop regional general 

permits if an NWP is not available, but this is an impractical and inefficient method for 

activities with minimal individual or cumulative adverse effects on the aquatic environment 

that are conducted across the Nation. Not all districts would develop these regional general 

permits for a variety of reasons. The regulated public, especially those companies that 

conduct work in more than one Corps district, would be adversely affected by the 

widespread use of regional general permits because of the greater potential for lack of 

consistency and predictability in the authorization of similar activities with minimal adverse 

effects on the aquatic environment. These companies would incur greater costs in their 

efforts to comply with different regional general permit requirements between Corps 

districts. Nevertheless, in some states Corps districts have issued programmatic general 

permits to take the place of this and other NWPs. However, this approach only works in 

states with regulatory programs comparable to the Corps Regulatory Program. 

2.2 National Modification Alternatives 

Since the Corps Nationwide Permit program began in 1977, the Corps has continuously 

strived to develop NWPs that authorize activities that result only in minimal adverse effects 

on the aquatic environment, individually or cumulatively. Every five years the Corps 

reevaluates the NWPs during the reissuance process, and may modify an NWP to address 

concerns for the aquatic environment. Utilizing collected data and institutional knowledge 

concerning activities authorized by the Corps regulatory program, the Corps reevaluates the 

potential impacts of activities authorized by NWPs. The Corps also uses substantive public 

comments on proposed NWPs to assess the expected impacts. This NWP was developed to 

authorize the placement of non-commercial, single boat, mooring buoys that have minimal 

adverse effects on the aquatic environment. The Corps has considered modifying or adding 

NWP general conditions, as discussed in the preamble of the Federal Register notice 

announcing the issuance of this NWP. 

In the February 16, 2011, Federal Register notice, the Corps requested comments on the 

proposed reissuance of this NWP. The Corps did not propose any changes to this NWP. 
5 

2.3 Regional Modification Alternatives 

An important aspect for the NWPs is the emphasis on regional conditions to address 

differences in aquatic resource functions, services, and values across the nation. All Corps 

divisions and districts are expected to add regional conditions to the NWPs to enhance 

protection of the aquatic environment and address local concerns. Division engineers can 

also revoke an NWP if the use of that NWP results in more than minimal adverse effects on 

the aquatic environment, especially in high value or unique wetlands and other waters. 

Corps divisions and districts also monitor and analyze the cumulative adverse effects of the 

NWPs, and if warranted, further restrict or prohibit the use of the NWPs to ensure that the 

NWPs do not authorize activities that result in more than minimal adverse effects on the 

aquatic environment. To the extent practicable, division and district engineers will use 

regulatory automated information systems and institutional knowledge about the typical 

adverse effects of activities authorized by NWPs, as well as substantive public comments, to 

assess the individual and cumulative adverse effects on the aquatic environment resulting 

from regulated activities. 

2.4 Case-specific On-site Alternatives 

Although the terms and conditions for this NWP have been established at the national level 

to authorize most activities that have minimal adverse effects on the aquatic environment, 

division and district engineers have the authority to impose case-specific special conditions 

on an NWP authorization to ensure that the authorized work will result in minimal adverse 

effects. 

General condition 22 requires the permittee to minimize and avoid impacts to waters of the 

United States to the maximum extent practicable on the project site. Off-site alternatives 

cannot be considered for activities authorized by NWPs. During the evaluation of a preconstruction notification, the district engineer may determine that additional avoidance and 

minimization is practicable. The district engineer may also condition the NWP 

authorization to require compensatory mitigation to offset losses of waters of the United 

States and ensure that the net adverse effects on the aquatic environment are minimal. As 

another example, the NWP authorization can be conditioned to prohibit the permittee from 

conducting the work during specific times of the year to protect spawning fish and shellfish. 

 If the proposed work will result in more than minimal adverse effects on the aquatic 

environment, then the district engineer will exercise discretionary authority and require an 

individual permit. Discretionary authority can be asserted where there are concerns for the 

aquatic environment, including high value aquatic habitats. The individual permit review 

process requires a project-specific alternatives analysis, including the consideration of offsite alternatives, and a public interest review. 

3.0 Affected Environment 
6 

The affected environment consists of navigable waters of the United States, which are 

defined at 33 CFR part 329. Generally, navigable waters of the United States are defined as 

“those waters that are subject to the ebb and flow of the tide and/or are presently used, or 

have been used in the past, or may be susceptible for use to transport interstate or foreign 

commerce.” [33 CFR 329.4] Using the estimate of the number of stream and river miles in 

the United States that was derived by Leopold, Wolman, and Miller (1964) (i.e., 3,250,000 

miles), and further assuming that approximately one percent of the rivers and streams within 

a tributary system are navigable-in-fact (Wood 2004), the amount of traditionally navigable 

rivers is estimated to be 325,000 miles. 

The Federal Geographic Data Committee has established the Cowardin system developed by 

the U.S. Fish and Wildlife Service (USFWS) (Cowardin et al. 1979) as the national standard 

for wetland mapping, monitoring, and data reporting (Dahl 2006) (see also 

http://www.fgdc.gov/standards/projects/FGDC-standards-projects/wetlands/fgdc-announce , 

accessed April 3, 2006). The Cowardin system is a hierarchical system which describes 

various wetland and deepwater habitats, using structural characteristics such as vegetation, 

substrate, and water regime as defining characteristics. Wetlands are defined by vegetation 

type, soils, and flooding frequency. Deepwater habitats are permanently flooded areas 

located below the wetland boundary. In rivers and lakes, deepwater habitats are usually 

more than two meters deep. 

There are five major systems in the Cowardin classification scheme: marine, estuarine, 

riverine, lacustrine, and palustrine (Cowardin et al. 1979). The marine system consists of 

open ocean on the continental shelf and its high energy coastline. The estuarine system 

consists of tidal deepwater habitats and adjacent tidal wetlands that are usually partially 

enclosed by land, but may have open connections to open ocean waters. The riverine 

system generally consists of all wetland and deepwater habitats located within a river 

channel. The lacustrine system generally consists of wetland and deepwater habitats located 

within a topographic depression or dammed river channel, with a total area greater than 20 

acres. The palustrine system generally includes all non-tidal wetlands and wetlands located 

in tidal areas with salinities less than 0.5 parts per thousand; it also includes ponds less than 

20 acres in size. Navigable waters of the United States are found in the marine and estuarine 

systems, and some riverine systems constitute navigable waters. 

The Emergency Wetlands Resources Act of 1986 (Public Law 99-645) requires the USFWS 

to submit wetland status and trends reports to Congress (Dahl 2006). The latest status and 

trends report, which covers the period of 1998 to 2004, is summarized in Table 3.1.

2004 (Dahl 2006).

Riverine deepwater habitats 6,813,300 

Estuarine subtidal habitats 17,717,800 

All aquatic habitats 149,058,500 

The acreage of lacustrine deepwater habitats does not include the open waters of Great 

Lakes (Dahl 2006), which are navigable waters. 

According to Hall et al. (1994), there are more than 204 million acres of wetlands and 

deepwater habitats in the State of Alaska, including approximately 174.7 million acres of 

wetlands. Wetlands and deepwater habitats comprise approximately 50.7 percent of the 

surface area in Alaska (Hall et al. 1994). 

Leopold, Wolman, and Miller (1964) estimated that there are approximately 3,250,000 miles 

of river and stream channels in the United States. This estimate is based on an analysis of 

1:24,000 scale topographic maps, by stream order. This estimate does not include many 

small streams. Many small streams are not mapped on 1:24,000 scale U.S. Geological 

Survey topographic maps (Leopold 1994) or included in other analyses (Meyer and Wallace 

2001). In a study of stream mapping in the southeastern United States, only 20% of the 

stream network was mapped on 1:24,000 scale topographic maps, and nearly none of the 

observed intermittent or ephemeral streams were indicated on those maps (Hansen 2001). 

For a 1:24,000 scale topographic map, the smallest tributary found by using 10-foot contour 

interval has drainage area of 0.7 square mile and length of 1,500 feet, and smaller channels 

are common throughout the United States (Leopold 1994). Due to the difficulty in mapping 

small streams, there are no accurate estimates of the total number of river or stream miles in 

the conterminous United States that may be classified as “waters of the United States.” 

Navigable waters of the United States also include marine habitats and estuarine subtidal 
8 

habitats, the extent of which Dahl (2006) estimates to be 128,600 and 17,717,800 acres, 

respectively in the conterminous United States (see Table 3.1). There are approximately 

97,537 miles of coast in the United States and its territories 

(http://www.ocrm.nos.noaa.gov/czm/czmsitelist.html , accessed July 5, 2006). 

Wetland functions are the biophysical processes that occur within a wetland (King et al. 

2000). Wetlands provide many functions, such as habitat for fish and shellfish, habitat for 

waterfowl and other wildlife, habitat for rare and endangered species, food production, plant 

production, flood conveyance, flood-peak reduction, flood storage, shoreline stabilization, 

water supply, ground water recharge, pollutant removal, sediment accretion, and nutrient 

uptake (NRC 1992). 

Functions provided by streams include sediment transport, water transport, transport of 

nutrients and detritus, habitat for many species of plants and animals (including endangered 

or threatened species), and maintenance of biodiversity (NRC 1992). Streams also provide 

hydrologic functions, nutrient cycling functions, food web support, and corridors for 

movement of aquatic organisms (Allan and Castillo 2007). 

Freshwater ecosystems provide services such as water for drinking, household uses, 

manufacturing, thermoelectric power generation, irrigation, and aquaculture; production of 

finfish, waterfowl, and shellfish; and non-extractive services, such as flood control, 

transportation, recreation (e.g., swimming and boating), pollution dilution, hydroelectric 

generation, wildlife habitat, soil fertilization, and enhancement of property values (Postel 

and Carpenter 1997). 

Marine ecosystems provide a number of ecosystem services, including fish production; 

materials cycling (e.g., nitrogen, carbon, oxygen, phosphorous, and sulfur); transformation, 

detoxification, and sequestration of pollutants and wastes produced by humans; support of 

ocean-based recreation, tourism, and retirement industries; and coastal land development 

and valuation, including aesthetics related to living near the ocean (Peterson and Lubchenco 

1997). 

Activities authorized by this NWP will provide services that are valued by society. The 

mooring buoys authorized by this NWP will support the public’s right to navigation. These 

mooring buoys will provide facilities for the safe anchorage of non-commercial vessels, 

including recreational boats. 

4.0 Environmental Consequences 

4.1 General Evaluation Criteria 

This document contains a general assessment of the foreseeable effects of the individual 

activities authorized by this NWP, the anticipated cumulative effects of those activities, and 

the potential future losses of waters of the United States that are estimated to occur until the 

expiration date of the NWP. In the assessment of these individual and cumulative effects, 
9 

the terms and limits of the NWP, notification requirements, and the standard NWP general 

conditions are considered. The supplementary documentation provided by division 

engineers will address how regional conditions affect the individual and cumulative effects 

of the NWP. 

The following evaluation comprises the NEPA analysis and the public interest review 

specified in 33 CFR 320.4(a)(1) and (2). 

The issuance of an NWP is based on a general assessment of the effects on public interest 

and environmental factors that are likely to occur as a result of using this NWP to authorize 

activities in waters of the United States. As such, this assessment must be speculative or 

predictive in general terms. Since NWPs authorize activities across the nation, projects 

eligible for NWP authorization may be constructed in a wide variety of environmental 

settings. Therefore, it is difficult to predict all of the indirect impacts that may be associated 

with each activity authorized by an NWP. For example, the NWP that authorizes 25 cubic 

yard discharges of dredged or fill material into waters of the United States may be used to 

fulfill a variety of project purposes. Indication that a factor is not relevant to a particular 

NWP does not necessarily mean that the NWP would never have an effect on that factor, but 

that it is a factor not readily identified with the authorized activity. Factors may be relevant, 

but the adverse effects on the aquatic environment are negligible, such as the impacts of a 

boat ramp on water level fluctuations or flood hazards. Only the reasonably foreseeable 

direct or indirect effects are included in the environmental assessment for this NWP. 

Division and district engineers will impose, as necessary, additional conditions on the NWP 

authorization or exercise discretionary authority to address locally important factors or to 

ensure that the authorized activity results in no more than minimal individual and 

cumulative adverse effects on the aquatic environment. In any case, adverse effects will be 

controlled by the terms, conditions, and additional provisions of the NWP. For example, 

Section 7 Endangered Species Act consultation will be required for activities that may affect 

endangered or threatened species or critical habitat. 

4.2 Impact Analysis 

This NWP authorizes the installation of mooring buoys for non-commercial vessels. This 

NWP authorizes structures in navigable waters of the United States, but it does not authorize 

discharges of dredged or fill material into those waters. 

Pre-construction notification is not required for activities authorized by this NWP, but the 

division engineer can add regional conditions to this NWP to require pre-construction 

notification for certain activities. If the district engineer determines that the adverse effects 

of a particular project are more than minimal after considering mitigation, then discretionary 

authority will be asserted and the applicant will be notified that another form of DA 

authorization, such as a regional general permit or individual permit, is required (see 33 

CFR 330.4(e) and 330.5). 

Additional conditions can be placed on proposed activities on a regional or case-by-case 

basis to ensure that the work has minimal adverse effects on the aquatic environment. 
10 

Regional conditioning of this NWP will be used to account for differences in aquatic 

resource functions, services, and values across the country, ensure that the NWP authorizes 

only those activities with minimal individual or cumulative adverse effects on the aquatic 

environment, and allow each Corps district to prioritize its workload based on where its 

efforts will best serve to protect the aquatic environment. Regional conditions can prohibit 

the use of an NWP in certain waters (e.g., high value waters or specific types of wetlands or 

waters), lower notification thresholds, or require notification for all work in certain 

watersheds or types of waters. Specific NWPs can also be revoked on a geographic or 

watershed basis where the adverse effects resulting from the use of those NWPs are more 

than minimal. 

In high value waters, division and district engineers can: 1) prohibit the use of the NWP in 

those waters and require an individual permit or regional general permit; 2) require 

notification for all activities in those waters; 3) add regional conditions to the NWP to 

ensure that the adverse environmental effects are minimal; or 4) for those activities that 

require notification, add special conditions to NWP authorizations, such as compensatory 

mitigation requirements, to ensure that the adverse effects on the aquatic environment are 

minimal. NWPs can authorize activities in high value waters as long as the individual and 

cumulative adverse effects on the aquatic environment are minimal. 

The construction and use of fills for temporary access for construction may be authorized by 

NWP 33 or regional general permits issued by division or district engineers. The related 

work must meet the terms and conditions of the specified permit(s). If the discharge is 

dependent on portions of a larger project that require an individual permit, this NWP will 

not apply. [See 33 CFR 330.6(c) and (d)] 

4.3 Cumulative Impacts 

The Council on Environmental Quality’s NEPA regulations define cumulative impact as: 

“the impact on the environment which results from the incremental impact of the action 

when added to other past, present, and reasonably foreseeable future actions regardless of 

what agency (Federal or non-Federal) or person undertakes such other actions. Cumulative 

impacts can result from individually minor but collectively significant actions taking place 

over a period of time.” [See 40 CFR 1508.7.] The NEPA cumulative impacts analysis for an 

NWP includes Federal and non-Federal activities that affect the Nation’s coastal waters, 

rivers, wetlands, and other aquatic resources, and is not limited to activities authorized by 

NWPs or other DA permits. The geographic scope of the cumulative impacts analysis is the 

United States, where the NWP can be used to authorize activities that require DA 

authorization. The temporal scope of the cumulative effects analysis includes past actions 

that have affected the Nation’s coastal waters, rivers, wetlands, and other aquatic resources, 

as well as present actions and reasonably foreseeable future actions that affect aquatic 

resources. 

There are many activities that contribute to cumulative effects on coastal waters, rivers, 

wetlands, and other aquatic resources in the United States, and alter the quantity and quality 

of those resources. Not all of those activities are regulated by the Corps under Section 10 of 
11 

the Rivers and Harbors Act of 1899. Federal, non-federal, and private activities contribute 

cumulative effects to aquatic resources. Activities authorized by DA permits, including 

structures and work in navigable waters, can directly or indirectly cause the loss of, or 

adversely affect the functions provided by, coastal waters, rivers, wetlands, and other 

aquatic resources. 

In addition to activities regulated and authorized by the Corps, including those authorized by 

this nationwide permit, other include federal, non-federal, and private actions not regulated 

by the Corps have cumulative effects on the Nation’s coastal waters, rivers, wetlands, and 

other aquatic resources, and adversely affect the quantity and quality of those resources. 

Changes in the use of uplands next to or near coastal waters, rivers, wetlands, and other 

aquatic resources may directly or indirectly diminish the ecological functions and services 

provided by those waters (e.g., Allan 2004 for rivers; Zedler and Kercher 2005 for 

wetlands). 

Actions that affect wetland quantity and quality include: land use changes that alter local 

hydrology (including water withdrawal), clearing and draining wetlands, constructing levees 

that sever hydrologic connections between rivers and floodplain wetlands, constructing 

other obstructions to water flow (e.g., dams, locks), constructing water diversions, 

accumulating nutrients and contaminants, and fire suppression (Brinson and Malvárez. 

2002). 

Actions that affect the quantity and quality of streams and rivers include habitat alterations 

caused by dam construction, channelization, and land use changes; changes in species 

composition caused by non-indigenous species; and additions of pollutants through either 

point sources or non-point sources (Allan and Castillo 2007). In urbanized and agricultural 

watersheds, the number of small stream channels has been substantially reduced, in part by 

activities that occurred between the 19th and mid-20th centuries (Meyer and Wallace 2001). 

Dahl (1990) estimates that approximately 53 percent of the wetlands in the conterminous 

United States were lost in the 200-year period covering the 1780s to 1980s. The annual rate 

of wetland loss has decreased substantially since the 1970s (Dahl 2006), when wetland 

regulation became more prevalent (Brinson and Malvárez. 2002). According to the 2006 

status and trends report, during the period of 1998 to 2004 urban development accounted for 

39% of wetland losses (88,960 acres), rural development resulted in 22% of wetland losses 

(51,440 acres), silviculture accounted for 8% of wetland losses (18,000 acres), and wetland 

conversion to deepwater habitats caused a 31% loss in wetland area (70,100 acres) (Dahl 

2006). Some of the losses are for non-jurisdictional wetlands and some losses may be due to 

activities not regulated under Section 404 of the Clean Water Act, such as unregulated 

drainage activities or water withdrawals. From 1998 to 2004, approximately 70,770 acres of 

wetlands were gained as a result of wetland restoration and conservation programs on 

agricultural land (Dahl 2006). Another source of wetland gain is conversion of uplands to 

wetlands (349,600 acres during the same time period) (Dahl 2006). It is important to 

understand that inventories of wetlands, streams, and other aquatic resources are likely to be 

incomplete (e.g., Dahl 2006. Meyer and Wallace 2001), which further complicates 

cumulative effects analysis. 
12 

The cumulative impacts of an NWP generally depends on the number of times the permit is 

used on a national basis. However, in a specific watershed, division or district engineers 

may determine that the cumulative adverse effects of activities authorized by NWPs are 

more than minimal. Division and district engineers will conduct more detailed assessments 

for geographic areas that are determined to be potentially subject to more than minimal 

cumulative adverse effects. Division and district engineers have the authority to require 

individual permits where the cumulative adverse effects are more than minimal, or add 

conditions to the NWP either on a case-by-case or regional basis to ensure that the 

cumulative adverse effects are minimal. When division or district engineers determine that 

a geographic area is subject to more than minimal cumulative adverse effects due to the use 

of the NWPs, they will use the revocation and modification procedure at 33 CFR 330.5. In 

reaching the final decision, they will compile information on the cumulative adverse effects 

and supplement this document. 

Based on reported use of this NWP during the period of August 1, 2009, to July 31, 2010, 

the Corps estimates that this NWP will be used approximately 65 times per year on a 

national basis. The activities authorized by this NWP generally do not result in a loss of 

waters of the United States. Compensatory mitigation is not normally required to offset the 

impacts resulting from the activities authorized by this NWP. The demand for these types of 

activities could increase or decrease over the five-year duration of this NWP. Using the 

current trend, approximately 325 activities could be authorized over a five year period until 

this NWP expires. Because of the small amount of impacts to waters of the United States 

expected to result from the use of this NWP over a five year period and the size of the 

Nation’s aquatic resource base as described in Section 3.0 of this document, the net effects 

on the aquatic environment resulting from the activities authorized by this NWP will be 

minimal. The Corps expects that the convenience and time savings associated with the use 

of this NWP will encourage applicants to design their projects within the scope of the NWP 

rather than request individual permits for projects which could result in greater adverse 

impacts to the aquatic environment. 

5.0 Public Interest Review 

5.1 Public Interest Review Factors (33 CFR 320.4(a)(1)) 

For each of the 20 public interest review factors, the extent of the Corps consideration of 

expected impacts resulting from the use of this NWP is discussed, as well as the reasonably 

foreseeable cumulative adverse effects that are expected to occur. The Corps decision 

process involves consideration of the benefits and detriments that may result from the 

activities authorized by this NWP. 

(a) Conservation: The activities authorized by this NWP may modify the natural resource 

characteristics of the project area. Compensatory mitigation, if required for activities 

authorized by this NWP, will result in the restoration, enhancement, establishment, or 
13 

preservation of aquatic habitats that will offset losses of conservation values. The adverse 

effects of activities authorized by this NWP on conservation will be minor. 

(b) Economics: The installation of mooring buoys will have positive impacts on the local 

economy. These activities will generate jobs and revenue for local contractors as well as 

revenue to marine supply companies that sell mooring buoys and associated materials, such 

as rope, chains, and anchors. 

(c) Aesthetics: Mooring buoys may alter the visual character of some waters of the United 

States. The extent and perception of these changes will vary, depending on the size and 

configuration of the mooring buoy, the nature of the surrounding area, and the public uses of 

the area. The increased human use of the project area and surrounding land will also alter 

local aesthetic values. 

(d) General environmental concerns: Activities authorized by this NWP have negligible 

adverse effects on general environmental concerns, such as water, air, noise, and land 

pollution. The adverse effects of the activities authorized by this NWP on general 

environmental concerns will be minor. Compensatory mitigation may be required by district 

engineers to ensure that the net adverse effects on the aquatic environment are minimal. It is 

important to note that the Corps scope of analysis is usually limited to impacts to aquatic 

resources. Specific environmental concerns are addressed in other sections of this 

document. 

(e) Wetlands: The installation of non-commercial, single-boat mooring buoys will have 

little or no adverse effects on wetlands, since these structures are located in open waters. 

This NWP does not authorize discharges of dredged or fill material into waters of the United 

States, including wetlands. Some wetlands may be temporarily impacted by the work 

through the use of temporary staging areas and access roads. These wetlands will be 

restored, unless the district engineer authorizes another use for the area, but the plant 

community may be different. 

Wetlands provide habitat, including foraging, nesting, spawning, rearing, and resting sites 

for aquatic and terrestrial species. The destruction of wetlands may alter natural drainage 

patterns. Wetlands reduce erosion by stabilizing the substrate. Wetlands also act as storage 

areas for stormwater and flood waters. Wetlands may act as groundwater discharge or 

recharge areas. The loss of wetland vegetation will adversely affect water quality because 

these plants trap sediments, pollutants, and nutrients and transform chemical compounds. 

Wetland vegetation also provides habitat for microorganisms that remove nutrients and 

pollutants from water. Wetlands, through the accumulation of organic matter, act as sinks 

for some nutrients and other chemical compounds, reducing the amounts of these substances 

in the water. 

General condition 22 requires avoidance and minimization of impacts to waters of the 

United States, including wetlands, at the project site. Compensatory mitigation may be 

required by district engineers to ensure that the net adverse effects on the aquatic 

environment are minimal. General condition 21 requires submittal of a pre-construction 
14 

notification prior to use of this NWP in designated critical resource waters and adjacent 

wetlands, which may include high value wetlands. District engineers can also add casespecific special conditions to the NWP authorization to provide protection to wetlands. 

(f) Historic properties: General condition 20 states that in cases where the district engineer 

determines that the activity may affect properties listed, or eligible for listing, in the 

National Register of Historic Places, the activity is not authorized, until the requirements of 

Section 106 of the National Historic Preservation Act have been satisfied.

(g) Fish and wildlife values: This NWP authorizes activities in navigable waters of the 

United States, including rivers, estuaries, oceans, and lakes, which provide habitat to many 

species of fish and wildlife. Activities authorized by this NWP will cause negligible 

changes to the habitat values of these waters. Open waters, including vegetated shallows, 

provide foraging areas, resting areas, and nesting and breeding grounds. Compensatory 

mitigation may be required by district engineers to restore, enhance, establish, and/or 

preserve wetlands and other aquatic habitats to offset losses of waters of the United States. 

These methods of compensatory mitigation will provide fish and wildlife habitat values. 

General condition 2 will reduce the adverse effects to fish and other aquatic species by 

prohibiting activities that substantially disrupt the necessary life cycle movements of 

indigenous aquatic species, unless the primary purpose of the activity is to impound water. 

Compliance with general conditions 3 and 5 will ensure that the authorized work has 

minimal adverse effects on spawning areas and shellfish beds, respectively. The authorized 

work cannot have more than minimal adverse effects on breeding areas for migratory birds, 

due to the requirements of general condition 4. 

Compliance with the Bald and Golden Eagle Protection Act (16 U.S.C. 668(a)-(d)), the 

Migratory Bird Treaty Act (16 U.S.C. 703; 16 U.S.C. 712), and the Marine Mammal 

Protection Act (16 U.S.C. 1361 et seq.), including any requirements to obtain take permits, 

is the responsibility of the project proponent for a particular NWP activity. 

Consultation pursuant to the essential fish habitat provisions of the Magnuson-Stevens 

Fishery Conservation and Management Act will occur as necessary for proposed NWP 

activities that may adversely affect essential fish habitat. Consultation may occur on a caseby-case or programmatic basis. Division and district engineers can impose regional and 

special conditions to ensure that activities authorized by this NWP will result in minimal 

adverse effects on essential fish habitat. 

(h) Flood hazards: The activities authorized by this NWP will not affect the flood-holding 

capacity of 100-year floodplains, including surface water flow velocities, because the 

activities authorized by this NWP occur in open, navigable waters. 

(i) Floodplain values: Activities authorized by this NWP will have no adverse effects on the 

flood-holding capacity of floodplains, or other floodplain values. The fish and wildlife 

habitat values of floodplains will not be adversely affected by activities authorized by this 

NWP, since the NWP authorizes activities in open, navigable waters. 
15 

 (j) Land use: Activities authorized by this NWP will not result in changes in land use, since 

it authorizes the installation of non-commercial, single-boat mooring buoys in navigable 

waters of the United States. Since the primary responsibility for land use decisions is held 

by state, local, and Tribal governments, the Corps scope of analysis is limited to significant 

issues of overriding national importance, such as navigation and water quality (see 33 CFR 

320.4(j)(2)). 

(k) Navigation: Activities authorized by this NWP must comply with general condition 1, 

which states that no activity may cause more than minimal adverse effects on navigation. 

(l) Shore erosion and accretion: The activities authorized by this NWP will have no adverse 

effects on shore erosion and accretion processes, since the NWP authorizes only noncommercial, single-boat mooring buoys in navigable waters of the United States. This NWP 

does not authorize discharges of dredged or fill material that could affect shore erosion and 

accretion processes. 

(m) Recreation: Activities authorized by this NWP may change the recreational uses of the 

area. The installation of non-commercial, single-boat mooring buoys may increase the use 

of particular waterways by recreational boaters. Certain recreational activities, such as bird 

watching, hunting, and fishing may be affected by the installation of mooring buoys and 

their use, but such effects are likely to be negligible. 

(n) Water supply and conservation: Activities authorized by this NWP will have no adverse 

effects on surface water and groundwater supplies. This NWP authorizes the installation of 

non-commercial, single-boat mooring buoys in navigable waters of the United States. 

Activities authorized by this NWP will not change demands for potable water in the region. 

Activities authorized by this NWP are unlikely to affect the quality of water supplies by 

adding pollutants and toxic chemicals to surface waters and groundwater. Many causes of 

water pollution, such as discharges regulated under Section 402 of the Clean Water Act, are 

outside the Corps scope of analysis. 

(o) Water quality: The activities authorized by this NWP will have negligible adverse effects 

on water quality. This NWP does not authorize discharges of dredged or fill material into 

waters of the United States, including wetlands. During the installation of mooring buoys 

authorized by this NWP, small amounts of oil and grease from construction equipment may 

be discharged into the waterway. Because most of the construction will occur during a 

relatively short period of time, the frequency and concentration of these discharges are not 

expected to have more than minimal adverse effects on overall water quality. 

(p) Energy needs: The activities authorized by this NWP will have negligible adverse effects 

on energy consumption in the area. 

(q) Safety: The activities authorized by this NWP will be subject to Federal, state, and local 

safety laws and regulations. Therefore, this NWP will not adversely affect the safety of the 

project area. 
16 

(r) Food and fiber production: Activities authorized by this NWP will have no adverse 

effects on food and fiber production, since it authorizes only non-commercial, single-boat 

mooring buoys in navigable waters of the United States. 

(s) Mineral needs: Activities authorized by this NWP are unlikely to increase demand for 

aggregates and stone, although some project proponents may use aggregates and stone to 

construct anchors for mooring buoys. Activities authorized by this NWP may increase the 

demand for cables and chains made from metals, which are made from mineral ores. 

(t) Considerations of property ownership: The NWP complies with 33 CFR 320.4(g), which 

states that an inherent aspect of property ownership is a right to reasonable private use. The 

NWP provides expedited DA authorization for the installation of non-commercial, singleboat mooring buoys in navigable waters of the United States. The installation of mooring 

buoys may improve navigable access for certain landowners. 

5.2 Additional Public Interest Review Factors (33 CFR 320.4(a)(2)) 

5.2.1 Relative extent of the public and private need for the proposed structure or work

This NWP authorizes the placement of mooring buoys in navigable waters of the United 

States, provided those structures have minimal adverse effects on the aquatic environment, 

individually and cumulatively. These activities satisfy public and private needs for 

anchorage structures for non-commercial vessels. The need for this NWP is based upon the 

large number of these activities that occur annually with minimal adverse effects on the 

aquatic environment. 

5.2.2 Where there are unresolved conflicts as to resource use, the practicability of using 

reasonable alternative locations and methods to accomplish the objective of the 

proposed structure or work

Most situations in which there are unresolved conflicts concerning resource use arise when 

environmentally sensitive areas are involved (e.g., special aquatic sites, including wetlands) 

or where there are competing uses of a resource. The nature and scope of the activity, when 

planned and constructed in accordance with the terms and conditions of this NWP, reduce 

the likelihood of such conflict. In the event that there is a conflict, the NWP contains 

provisions that are capable of resolving the matter (see Section 1.2 of this document). 

General condition 22 requires permittees to avoid and minimize adverse effects to waters of 

the United States to the maximum extent practicable on the project site. Consideration of 

off-site alternative locations is not required for activities that are authorized by general 

permits. General permits authorize activities that have minimal individual and cumulative 

adverse effects on the aquatic environment and overall public interest. District engineers 

will exercise discretionary authority and require an individual permit if the proposed work 

will result in more than minimal adverse environmental effects on the project site. The 

consideration of off-site alternatives can be required during the individual permit process. 
17 

5.2.3 The extent and permanence of the beneficial and/or detrimental effects which the 

proposed structure or work is likely to have on the public and private uses to which 

the area is suited

The nature and scope of the work authorized by the NWP will most likely restrict the extent 

of the beneficial and detrimental effects to the area immediately surrounding the structures. 

Activities authorized by this NWP will have minimal adverse effects on the aquatic 

environment. 

The terms, conditions, and provisions of the NWP were developed to ensure that individual 

and cumulative adverse environmental effects are minimal. Specifically, NWPs do not 

obviate the need for the permittee to obtain other Federal, state, or local authorizations 

required by law. The NWPs do not grant any property rights or exclusive privileges (see 33 

CFR 330.4(b) for further information). Additional conditions, limitations, restrictions, and 

provisions for discretionary authority, as well as the ability to add activity-specific or 

regional conditions to this NWP, will provide further safeguards to the aquatic environment 

and the overall public interest. There are also provisions to allow suspension, modification, 

or revocation of the NWP. 

5.2.4 Endangered and threatened species.

The Corps believes that the procedures currently in place result in proper coordination under 

Section 7 of the Endangered Species Act (ESA) and ensure that activities authorized by this 

NWP will not jeopardize the continued existence or any listed threatened and endangered 

species or result in the destruction or adverse modification of critical habitat. The Corps 

also believes that current local procedures in Corps districts are effective in ensuring 

compliance with ESA. 

Under general condition 19, no activity is authorized under any NWP which “may affect” a 

listed species or critical habitat, unless Section 7 consultation addressing the effects of the 

proposed activity has been completed. 

Each activity authorized by an NWP is subject to general condition 19, which states that 

“[n]o activity is authorized under any NWP which is likely to directly or indirectly 

jeopardize the continued existence of a threatened or endangered species or a species 

proposed for such designation, as identified under the Federal Endangered Species Act 

(ESA), or which will directly or indirectly destroy or adversely modify the critical habitat of 

such species.” In addition, general condition 19 explicitly states that the NWP does not 

authorize the taking of threatened or endangered species, which will ensure that permittees 

do not mistake the NWP authorization as a Federal authorization to take threatened or 

endangered species. General condition 19 also requires non-federal permittees to notify the 

district engineer if any listed species or designated critical habitat might be affected or is in 

the vicinity of the project, or if the project is located in designated critical habitat. This 

general condition also states that, in such cases, non-federal permittees shall not begin work 

on the activity until notified by the district engineer that the requirements of the ESA have 
18 

been satisfied and that the activity is authorized. 

Under the current Corps regulations (33 CFR 325.2(b)(5)), the district engineer must review 

all permit applications for potential impacts on threatened and endangered species or critical 

habitat. For the NWP program, this review occurs when the district engineer evaluates the 

pre-construction notification or request for verification. Based on the evaluation of all 

available information, the district engineer will initiate consultation with the U.S. Fish and 

Wildlife Service (USFWS) or National Marine Fisheries Service (NMFS), as appropriate, if 

he or she determines that the regulated activity may affect any threatened and endangered 

species or critical habitat. Consultation may occur during the NWP authorization process or 

the district engineer may exercise discretionary authority to require an individual permit for 

the proposed activity and initiate consultation through the individual permit process. If ESA 

consultation is conducted during the NWP authorization process without the district 

engineer exercising discretionary authority, then the applicant will be notified that he or she 

cannot proceed with the proposed activity until ESA consultation is complete. If the district 

engineer determines that the activity will have no effect on any threatened and endangered 

species or critical habitat, then the district engineer will notify the applicant that he or she 

may proceed under the NWP authorization. 

 

Corps districts have, in most cases, established informal or formal procedures with local 

offices of the USFWS and NMFS, through which the agencies share information regarding 

threatened and endangered species and their critical habitat. This information helps district 

engineers determine if a proposed activity may affect endangered species or their critical 

habitat and, if necessary, initiate consultation. Corps districts may utilize maps or databases 

that identify locations of populations of threatened and endangered species and their critical 

habitat. Where necessary, regional conditions are added to NWPs to require notification for 

activities that occur in known locations of threatened and endangered species or critical 

habitat. For activities that require agency coordination during the pre-construction 

notification process, the USFWS and NMFS will review the proposed work for potential 

impacts to threatened and endangered species and their critical habitat. Any information 

provided by local maps and databases and any comments received during the preconstruction notification review process will be used by the district engineer to make a “no 

effect” or “may affect” decision. 

Based on the safeguards discussed above, especially general condition 19 and the NWP 

regulations at 33 CFR 330.5(f), the Corps has determined that the activities authorized by 

this NWP will not jeopardize the continued existence of any listed threatened or endangered 

species or result in the destruction or adverse modification of designated critical habitat. 

Although the Corps continues to believe that these procedures ensure compliance with ESA, 

the Corps has taken some steps to provide further assurance. Corps district offices have met 

with local representatives of the USFWS and NMFS to establish or modify existing 

procedures, where necessary, to ensure that the Corps has the latest information regarding 

the existence and location of any threatened or endangered species or their critical habitat. 

Corps districts can also establish, through local procedures or other means, additional 

safeguards that ensure compliance with ESA. Through formal consultation under Section 7 

of the Endangered Species Act, or through other coordination with the USFWS and/or the 
19 

NMFS, as appropriate, the Corps will establish procedures to ensure that the NWP will not 

jeopardize any threatened and endangered species or result in the destruction or adverse 

modification of designated critical habitat. Such procedures may result in the development 

of regional conditions added to the NWP by the division engineer, or in special conditions to 

be added to an NWP authorization by the district engineer. 

6.0 Determinations 

6.1 Finding of No Significant Impact 

[To be determined after review of comments received in response to the proposal.] 

6.2 Public Interest Determination 

[To be determined after review of comments received in response to the proposal.] 

6.3 Section 176(c) of the Clean Air Act General Conformity Rule Review 

This NWP has been analyzed for conformity applicability pursuant to regulations 

implementing Section 176(c) of the Clean Air Act. It has been determined that the activities 

authorized by this permit will not exceed de minimis levels of direct emissions of a criteria 

pollutant or its precursors and are exempted by 40 CFR 93.153. Any later indirect 

emissions are generally not within the Corps continuing program responsibility and 

generally cannot be practicably controlled by the Corps. For these reasons, a conformity 

determination is not required for this NWP. 

6.4 Compliance with Relevant Executive Orders 

6.4.1 EO 13175, Consultation and Coordination With Indian Tribal Governments

The issuance of this NWP does not have tribal implications. It is generally consistent with 

current agency practice and will not have substantial direct effects on tribal governments, on 

the relationship between the federal government and the Indian tribes, or on the distribution 

of power and responsibilities between the federal government and Indian tribes. Regional 

conditions or other local NWP modifications may be added to this NWP by division and 

district engineers to protect aquatic resources of interest to Tribes, as part of the Corps 

responsibility to protect trust resources. 

6.4.2 EO 11988, Floodplain Management

Compliance with NWP general condition 10, fills in 100-year floodplains, will minimize 

impacts of potential flooding on human health, safety, and welfare, as well as the natural and 

beneficial values of floodplains. 

6.4.3 EO 12898, Environmental Justice
20 

In accordance with Title III of the Civil Right Act of 1964 and Executive Order 12898, it 

has been determined that the issuance of this NWP would not directly or through contractual 

or other arrangements, use criteria, methods, or practices that discriminate on the basis of 

race, color, or national origin nor would it have a disproportionate effect on minority or lowincome communities. 

6.4.4 EO 13112, Invasive Species

The issuance of this NWP will not cause or promote the introduction or spread of invasive 

species in the United States. The district engineer may add special conditions to an NWP 

authorization to require the permittee to control the introduction or spread of invasive 

species at the project site. 

6.4.5 EO 13212 and 13302, Actions to Expedite Energy-Related Projects

The issuance of this NWP will support the policy established in these Executive Orders, by 

providing an efficient form of DA authorization for minor activities associated with energyrelated projects.
