A.
Applicability
(1) This section
applies to the maintenance, repair, reconstruction, rehabilitation, replacement
or minor construction of a State Transportation Facility carried out by, or
under the authority of, the Maine Department of Transportation (MaineDOT) or
the Maine Turnpike Authority, including any testing or preconstruction
engineering, and associated technical support services.
(2) This section does not apply to an
activity within a coastal sand dune system.
NOTE: The construction of a transportation facility other
than roads and associated facilities may be subject to the Storm Water
Management Law, 38 M.R.S.A. Section
420- D.
B.
Standards
(1) Photographs of the area to be altered by
the activity must be taken before work on the site begins. The photographs must
be kept on file and be made available at the request of the DEP.
(2) The activity must be reviewed by the
Department of Inland Fisheries and Wildlife and the Department of Marine
Resources, as applicable. The applicant must coordinate with the reviewing
agencies and incorporate any recommendations from those agencies into the
performance of the activity.
(3)
All construction activities undertaken must be detailed in a site-specific Soil
Erosion and Water Pollution Control Plan and conducted in accordance with Maine
DOT's Best Management Practices for Erosion and Sediment Control, dated January
2000, and Standard Specifications, dated December 2002.
(4) Alignment changes may not exceed a
distance of 200 feet between the old and new center lines in any natural
resource.
(5) The activity may not
alter more than 300 feet of shoreline (both shores added together) within a
mile stretch of any river, stream or brook, including any bridge width or
length of culvert.
(6) The activity
may not alter more than 150 feet of shoreline (both shores added together)
within a mile stretch of any outstanding river segment identified in 38
M.R.S.A. §480- P, including any bridge width
or length of culvert.
(7) The
activity must minimize wetland intrusion. The activity is exempt from the
provisions of Chapter 310, the Wetland and Water bodies Protection Rules, if
the activity alters less than 15,000 square feet of natural resources per mile
of roadway (centerline measurement) provided that the following impacts are not
exceeded within the 15,000 square foot area:
(a) 1,000 square feet of coastal wetland
consisting of salt tolerant vegetation or shellfish habitat; or
(b) 5,000 square feet of coastal wetland not
containing salt tolerant vegetation or shellfish habitat; or
(c) 1,000 square feet of a great pond.
All other activities must be performed in compliance with all
sections of Chapter 310, the Wetland Protection Rules, except 310.2(C), 5(A),
9(A), 9(B) and 9(C).
(8) The activity may not permanently block
any fish passage in any watercourse containing fish. The applicant must
coordinate with the reviewing agencies listed in paragraph 2 above to improve
fish passage and incorporate any recommendations from those agencies into the
performance of the activity.
NOTE: For guidance on meeting the design objectives for fish
passage, including peak flow, maximum velocity, mining depth and gradient, see
the MaineDOT Waterbody and Wildlife Crossing Policy and Design Guide (July
2008), developed in conjunction with state and federal resource and regulatory
agencies.
(9) Rocks may not
be removed from below the normal high water line of any coastal wetland,
freshwater wetland, great pond, river, stream or brook except to the minimum
extent necessary for completion of work within the limits of
construction.
(10) If work is
performed in a river, stream or brook that is less than three feet deep at the
time and location of the activity, the applicant must isolate the work area
from the resource and divert stream flows around the work area, maintaining
downstream flows while work is in progress.
(11) Wheeled or tracked equipment may not
operate in the water. Equipment operating on the shore may reach into the water
with a bucket or similar extension. Equipment may cross streams on rock, gravel
or ledge bottom. If avoiding the operation of wheeled or tracked equipment in
the water is not possible, the applicant must explain the need to operate in
the water. Approval from the DEP to operate in the water must be in writing,
and any recommendations from the DEP must be incorporated into the performance
of the activity.
(12) All wheeled
or tracked equipment that must travel or work in a vegetated wetland area must
travel and work on mats or platforms.
(13) Any debris or excavated material must be
stockpiled either outside the wetland or on mats or platforms. Erosion and
sediment control best management practices must be used, where necessary, to
prevent sedimentation. Any debris generated during the activity must be
prevented from washing downstream and must be removed from the wetland or water
body. Disposal of debris must be in conformance with the Maine Hazardous Waste,
Septage and Solid Waste Management Act, 38 M.R.S.A. Section
1301et
seq.
(14) Work below the
normal high water line of a great pond, river, stream or brook must be done at
low water except for emergency work or work agreed to by the resource agencies
listed in paragraph 2 above.
(15)
Perimeter controls must be installed before the work starts. Disturbance of
natural resources beyond the construction limits shown on the plans is not
allowed under this rule.
NOTE: Guidance on the location of construction limits can be
obtained from the on site Construction Manager.
(16) 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 a manner that exposes all surfaces to the air for a period of at
least 21 days prior to construction. Wood treated with creosote or
pentachlorophenol may not be used where it will contact water.
(17) A temporary road for equipment access
must be constructed of crushed stone, blasted ledge, or similar materials that
will not cause sedimentation or restrict fish passage. Such roads must be
completely removed at the completion of the activity. In addition, any such
temporary roads which are in rivers, streams or brooks, must allow for a
passage of stormwater flows associated with a 10-year storm.
(18) Non-native species may not be planted in
restored areas.
(19) Disposal of
debris must be in conformance with Maine Hazardous Waste, Septage and Solid
Waste Management Act, 38 M.R.S.A. Sections
1301et
seq.
(20) Disturbance of
vegetation must be avoided, if possible. Where vegetation is disturbed outside
of the area covered by any road or structure construction, it must be
reestablished immediately upon completion of the activity and must be
maintained.
(21) A vegetated area
at least 25 feet wide must be established and maintained between any new
stormwater outfall structure and the high water line of any open water body. A
velocity reducing structure must be constructed at the outlet of the stormwater
outfall that will create sheet flow of stormwater, and prevent erosion of soil
within the vegetated buffer. If the 25 foot vegetated buffer is not
practicable, the applicant must explain the reason for a lesser setback in
writing. Approval from the DEP must be in writing and any recommendations must
be incorporated into the activity.
