A.
Applicability
(1) This section
applies to the construction of a new, or the replacement of an existing, public
boat ramp or carry-in launch area, including associated parking and accessways,
in or adjacent to a protected natural resource by a public natural resource
agency, Maine Department of Transportation, municipality, or owners of a
federally licensed hydropower project within the resource affected by the
hydropower project. This section does not apply if a portion of the ramp or
related facilities is located in, on or over emergent marsh vegetation or
intertidal mudflat.
(2) This
section applies to the construction of up to 2 launch lanes at a facility
provided no more than 2 lanes exist or will exist at the completion of the
activity.
(3) This section does not
apply to a new boat ramp on a lake infested with aquatic invasive plants, as
defined in 38 M.R.S.A. Section
410- N. The Department of
Environmental Protection identifies and maintains a list of these infested
lakes.
NOTE: A permit will be required from the US Army Corps of
Engineers for the following types of projects:
(a) Any activity involving open trench
excavation in a waterbody;

activity in coastal waterways;
(c)
Any activity within a river, stream or brook between October 2 and July 14;
or

all aquatic habitats in the watersheds of the following rivers and streams,
including all tributaries to the extent that they are currently or were
historically accessible for salmon migration: St. Croix, Boyden, Dennys, Hobart
Stream, Aroostook, East Machias, Machias, Pleasant, Narraguagus, Tunk Stream,
Patten Stream, Orland, Penobscot, Passagassawaukeag, Union, Ducktrap,

must be submitted within 20 days of the activity's completion. The photographs
must be sent with a copy of the notification form or labeled with the
applicant's name and the town in which the activity took place.
(3) If the project results in a new or
expanded access drive or parking area, the project design plan, erosion control
plan and a request for review for an activity on great ponds classified as GPA
under 38 M.R.S.A. Section
465-A must be submitted to the
DEP's Division of Watershed Management (DWM) prior to submitting the
notification form to the DEP. A certification from DWM must be obtained and
must be included with the notification form, along with final project plans and
the erosion control plan, when it is submitted to the DEP.
(4) If the proposed activity involves work
below the mean low water line of a waterbody, the applicant shall submit a copy
of the project design plan along with a copy of the notification form to the
Department of Conservation, Bureau of Parks and Lands, Submerged Lands Program
(State House Station #22 Augusta, Maine 04333) at the time the notification
form is submitted to the DEP. Work on the activity may not begin until a lease
or easement is obtained or the Bureau of Parks and Lands has provided
notification that one is not necessary.
NOTE: Processing of a request for a lease or easement may
require several weeks of review by the Bureau of Public Lands.
(5) If the proposed activity is
located within a coastal wetland area, the applicant shall submit, along with
the notification form, a letter from both the Department of Inland Fisheries
and Wildlife and the Department of Marine Resources that describes times of the
year in which the construction of the boat ramp may occur.
(6) If the proposed activity is located
within a freshwater wetland, great pond, river, stream or brook, the applicant
shall submit, along with the notification form, a letter from the Department of
Inland Fisheries and Wildlife that describes times of the year in which the
construction of the boat ramp may occur.
C.
Standards
(1) The erosion control plan must be
followed. Erosion of soil or fill material from disturbed areas into the
resource must be prevented. The following measures must be taken:
(a) Staked hay bales or silt fence must be
properly installed between the area of soil disturbance and the resource before
the activity begins;
(b) Hay bales
or silt fence barriers must be maintained until the disturbed area is
permanently stabilized;
(c) Within
7 calendar days following the completion of any soil disturbance, and prior to
any storm event, mulch must be spread on any exposed soils;
(d) All disturbed soils must be permanently
stabilized; and
(e) Within 30 days
of final stabilization of the site, any silt fence must be removed.
NOTE: For guidance on erosion and sedimentation controls,
consult the Maine Erosion and Sediment Control BMPs, dated March 2003. This
handbook and other references are available from the DEP.
(2) A hard-surfaced launch must be
used where boats will be launched from trailers, and must meet the following
specifications:
(a) The underwater portions of
the ramp, at the time of construction, must be constructed of reinforced
precast concrete planks, panels or slabs;
(b) The portion of the ramp used by the
towing vehicle may not have a slope that exceeds 15%; the portion of the ramp
used by the trailer only may not have a slope that exceeds 20%;
(c) The width of the hard surfaced launch
lane(s) may not exceed 20 feet as measured parallel to shore;
(d) The upper most 6 inches of the base must
consist of crushed rock or crushed or screened gravel having 5% or less passing
a 200 mesh sieve; and
(e) Fill
slopes at or below the normal high water line must be protected with riprap.
Riprap installation must meet the standards for riprap in PBR Section
8, "Shoreline
stabilization".
(3) An
additional area of up to 8 feet wide as measured parallel to shore may be
constructed using bituminous pavement, precast concrete planks, panels or slabs
to support docking systems.
(4) A
carry-in launch area for small boats must:
(a)
Consist of gravel, rock, sand, vegetation, or other erosion resistant
materials;
(b) Have a grade not
exceeding 18%; and
(c) Be Limited,
below the low water line, to constructing a path up to 6 feet wide, measured
parallel to shore, consisting of cobble, rock or concrete planks, to access
deeper water to float watercraft.
(5) A vegetated buffer zone at least 25 feet
in width must be maintained between any new or expanded parking area and the
waterbody.
(6) A parking area or
access road may not be located in a protected natural resource, except that an
access roadway may cross a stream if the requirements of PBR Section
10"Stream crossings" are
met.
(7) Any new or expanded
parking area or roadway must divert stormwater runoff away from the ramp to an
area where it may infiltrate into the ground before reaching the
waterbody.
(8) Machinery may
operate below the water line only when necessary to excavate or place material
below the existing water level and must travel and operate on temporary mats or
portions of the ramp that have been constructed.
(9) Timing of the activity must conform to
the recommendations of biologists from the Department of Inland Fisheries and
Wildlife or the Department of Marine Resources, as appropriate, as described in
letters submitted along with the notification form.
(10) Any debris generated during the work
must be prevented from washing downstream and must be removed from the wetland
or water body. Disposal of debris must be in conformance with Maine Hazardous
Waste, Septage and Solid Waste Management Act, 38 M.R.S.A Section
1301et
seq.
(11) Uncured concrete
may not be placed directly into the water. Concrete must be pre-cast and cured
at least three weeks before placing in the water or, where necessary, must be
placed in forms and cured at least one week before the forms are removed. No
washing of tools, forms, etc. may occur in or adjacent to the waterbody or
wetland.
(12) The use of untreated
lumber is preferred. Lumber pressure-treated with chromated copper arsenate
(CCA) may be used only if necessary and only if use is allowed under federal
law and not prohibited from sale under 38 M.R.S.A. §1682, and provided it is cured on
dry land in such a manner as to expose all surfaces to the air for a period of
at least 21 days prior to construction. Wood treated with creosote or
pentachlorophenol shall not be used where it will contact
water.
