APPENDIX Z
MINIMUM WORK REQUIREMENTS
Z-1. General. Aquatic plant control operations conducted under Local Cooperation Agreements
(LCAs) are authorized by Section 104 of the Rivers and Harbors Act of 1958, codified as
amended at 33 USC 610, the Aquatic Plant Control (APC) program. Work performed under the
LCA shall be in conformance with all applicable Federal, State and local laws, regulations, and
ordinances. All operations carried out, or caused to be carried out, by the State pursuant to the
LCA shall conform as a minimum to the requirements in this Appendix which shall be attached
and made a part of the LCA. The State shall, within 60 days of the effective date of the LCA,
submit to the Corps for approval a Program Management Plan which demonstrates how these
minimum requirements will be met by the State in operations and management of the program.
Z-2. Eligibility. Water bodies eligible for treatment under the program are navigable waters
(including waterbodies navigable within themselves) that demonstrate a federal interest and a
positive benefit/cost ratio. Reservoirs, channels, harbors, and other waterbodies managed under
the Operations and Maintenance program of the Corps of Engineers or other Federal Agencies are
not eligible for inclusion under this program other than for experimental work. Federal interest
and navigability will be determined by the availability of the water body for use by the general
boating public. The specific eligibility criteria are:
a. The water body must have unrestricted access to the boating public by way of an
established boat ramp or directly navigable to, or from, another eligible waterbody.
b. The water body must have a sign at each boat ramp stating that it is a public boat ramp
or use area.
c. The water body must have at least one public directional sign on the nearest paved road
or main thoroughfare indicating the way to the area.
d. The boat ramp must have sufficient space to safely turn a vehicle and trailer around and
then park with enough room to avoid being struck by the next backing trailer.
e. There shall be no intimidating conditions in the boat ramp area which could be
construed as being threatening to the user (no trespassing signs, pillars with chains, etc.)
Z-3. Control Methods. Environmental manipulation, mechanical, chemical, biological, snagging
methods, or an integrated mixture of these methods may be used in accordance with this appendix
and the approved Annual Work Plan (see Appendix 14-F). The methods selected for use and
approval thereof will consider the demonstrated effectiveness, economic justification, selectivity
to target species, and potential adverse environmental effects. Research or unproven methods are
not allowable under the LCA except as they may be used to provide operational benefits.
a. Environmental Manipulation. Alteration of the physical environment of the target
species through dredging, water level manipulation, shading or other similar procedures may be
used to manage plants susceptible to these methods. Amortization over the anticipated period of
control may be used in the computation of benefit/cost ratio.
