Current through Register Vol. 49, No. 13, September 23, 2024
Subpart
1.
Goals.
It is the goal of the department to limit the placement of
any fill material into public waters in order to:
A. minimize encroachment, change, or damage
to the environment;
B. regulate the
quantity and quality of fill and the purposes for which filling may be allowed
based upon the capabilities of the waters to assimilate the material;
and
C. maintain consistency with
floodplain, shoreland, and wild and scenic rivers management standards and
ordinances.
Subp. 2.
Scope.
Filling as used in this part involves placement of unconfined
or loosely confined materials in public waters.
Subp. 3.
Prohibited placement.
Placement is prohibited in the following cases:
A. to achieve vegetation control;
B. to create upland areas, except where
expressly provided herein;
C. to
stabilize beds of public waters which cannot support fill materials because of
excessive depths of muck, steep bank, bed slope, or other conditions;
D. to stabilize or impound the site of active
springs;
E. to dispose of rock,
sand, gravel, or any other solid material resulting from activities carried out
above the ordinary high water level;
F. to construct a roadway or pathway, or
create or improve land accesses from peripheral shorelands to islands, or to
facilitate land transportation across the waters; however, when a project is
proposed by a federal, state, or local government agency and this provision
would prevent or restrict the project, or create a major conflict with other
public purposes or interests, the commissioner may waive this provision if:
(1) there is no other feasible and practical
alternative to the project that would have less environmental impact;
and
(2) the public need for the
project rules out the no-build alternative; or
G. filling posted fish spawning
areas.
Subp. 4.
No
permit required.
No permit is required for the following activities unless
prohibited under subpart 3:
A. to
install a beach sand blanket if:
(1) the sand
or gravel layer does not exceed six inches in thickness, 50 feet in width along
the shoreline, or one-half the width of the lot, whichever is less, and does
not extend more than ten feet waterward of the ordinary high water
level;
(2) the beach sand blanket
does not cover emergent vegetation, unless authorized by an aquatic plant
management permit; and
(3) local
watershed district and local zoning officials are given at least seven days
notice by the landowner;
B. for one additional installation of a sand
or gravel layer subsequent to an initial installation at the same location and
not exceeding the same amounts and dimensions allowed under item A;
or
C. to place fill in a public
watercourse having a total drainage area, at its mouth, of five square miles or
less, if the watercourse is not an officially designated trout stream and the
placement of fill does not result in:
(1) any
diversions of water from the drainage area;
(2) any impoundment of waters by damming the
watercourse; or
(3) any actions
that would result in erosion and cause sedimentation of downstream waters as
determined by the county or local soil and water conservation
district.
Subp.
5.
Permits required.
Permits are required for the placement of fill in public
waters, except as provided under subparts 3 and 4, and a project must meet all
of the following requirements:
A. the
project does not exceed more than a minimum encroachment, change, or damage to
the environment, particularly the ecology of the waters;
B. the fill consists of clean inorganic
material that is free of pollutants and nutrients;
C. the existence of a stable, supporting
foundation is established by appropriate means, including soil boring data
where deemed necessary by the commissioner;
D. where erosion protection is deemed
necessary by the commissioner, the site conditions and fill material are
capable of being stabilized by an approved erosion control method such as
riprap, retaining wall, or other method which is consistent with existing land
uses on the affected public water;
E. the proposed project represents the
minimal impact solution to a specific need with respect to all other reasonable
alternatives;
F. the size, shape,
depths, shoreline, and bottom character and topography, and susceptibility of
the beds of public waters to actions of wind, waves, and currents are such that
the fill will be stable;
G. adverse
effects on the physical or biological character of the waters are subject to
feasible and practical measures to mitigate the effects;
H. the proposed filling is consistent with
applicable floodplain, shoreland, and wild and scenic rivers management
standards and ordinances for the waters involved; and
I. the proposed filling is consistent with
water and related land management plans and programs of local and regional
governments, provided such plans and programs are consistent with state plans
and programs.
