1) The Corps of Engineers believes that there may be jurisdictional aquatic resources in the
review area, and the requestor of this PJD is hereby advised of his or her option to request
and obtain an approved JD (AJD) for that review area based on an informed decision after
having discussed the various types of JDs and their characteristics and circumstances when
they may be appropriate.
2) In any circumstance where a permit applicant obtains an individual permit, or a Nationwide
General Permit (NWP) or other general permit verification requiring "pre- construction
notification" (PCN), or requests veriiication for a non-reporting NWP or other general permit,
and the permit applicant has not requested an AJD for the activity, the permit applicant is
hereby made aware that: (1) the permit applicant has elected to seek a permit authorization
based on a PJD, which does not make an official determination of jurisdictional aquatic
resources; (2) the applicant has the option to request an AJD before accepting the terms and
conditions of the permit authorization, and that basing a permit authorization on an AJD could
possibly result in less cornpensatory mitigation being required or different special conditions;
(3) the applicant has the right to request an individual permit rather than accepting the terms
and conditions of the NWP or other general permit authorization; (4) the applicant can accept
a permit authorization and thereby agree to comply with all the terms and conditions of that
permit, including whatever mitigation requirements the Corps has determined to be necessary;
(5) undertaking any activity in reliance upon the subject permit authorization without
requesting an AJD constitutes the applicant's acceptance of the use of the PJD; (6) accepting a
permit authorization (e.g., signing a proffered individual permit) or undertaking any activity in
reliance on any form of Corps permit authorization based on a PJD constitutes agreement that
all aquatic resources in the review area affected in any way by that activity will be treated as
jurisdictional, and waives any challenge to such jurisdiction in any administrative or judicial
compliance or enforcement action, or in any administrative appeal or in any Federal court;
and (7) whether the applicant elects to use either an AJD or a PJD, the JD will be processed
as soon as practicable. Further, an AJD, a proffered individual permit (and all terms and
conditions contained therein), or individual permit denial can be administratively appealed
pursuant to 33 C.F.R. Part 331. If, during an administrative appeal, it becomes appropriate to
make an official determination whether geographic jurisdiction exists over aquatic resources
in the review area, or to provide an official delineation of jurisdictional aquatic resources in
the review area, the Corps will provide an AJD to accomplish that result, as soon as is
practicable. This PJD finds that there "may be" waters of the U.S. and/or that there "may be"
navigable waters of the U.S. on the subject review area, and identifies all aquatic features in
the review area that could be affected by the proposed activity, based on the following
information:

X 2- Dominance Test is >50%
X 3- Prevalence Index is <_3.0�
Problematic Hydrophytic Vegetation� (Explain)
'Indicators of hydric soil and wetland hydrology must t
present, unless disturbed or problematic.
Definitions of Five Vegetation Strata:
Tree - Woody plants, excluding woody vines,
approximately 20 ft(6 m) or more in height and 3 in.
(7.6 cm) or larger in diameter at breast height (DBH).
Sapling - Woody plants, excluding woody vines,
approximately 20 ft(6 m) or more in height and less
than 3 in. (7.6 cm) DBH.
Shrub - Woody Plants, excluding woody vines,
approximately 3 to 20 ft(1 to 6 m) in height.
Herb - All herbaceous (non-woody) plants, including
herbaceous vines, regardless of size, and woody
plants, except woody vines, less than approximately 3
ft (1 m) in height.
Woody Vine - All woody vines, regardless of height.
