A. Limited repair and maintenance of an
existing structure located in a jurisdictional area is allowed under §
9.6.1 of this Part, as long as the repair or maintenance does not increase the
size of the structure vertically or horizontally. Some limited structural
changes also may be exempt, as specifically provided below. For purposes of
§ 9.6.3 of this Part, repair and maintenance is limited to routine
activities necessary to ensure the upkeep of structures built in accordance
with all necessary Federal, State and local permits.
1. Normal maintenance of existing or approved
structures and accessory structures to maintain their integrity and condition;
or
2. Replacement of functional
drainage structures provided that:
a. Culverts
of more than fifty feet (50') are the same, size, length, capacity and invert
elevation as the present structure;
b. Culverts of fifty feet (50') or less
maintain the same slope, a nominally equivalent cross-sectional area and the
same invert elevation as the present structure with no more than five foot (5')
extensions in length on either end;
c. The project or activity does not result in
sediment transport to freshwater wetlands or buffers or result in any filling,
draining, or impoundment of freshwater wetlands, buffers or floodplains beyond
what was approved or existing; and
d. The property owner maintains site plans
which detail the condition of the drainage structure as it existed prior to
replacement. A riprap scour pad not greater than ten feet (10') in length may
be placed at the culvert outfall if an erosion problem is evident, provided
that the access for fish and wildlife is not impeded; or
3. Cleaning of drainage pipes, culverts,
catch basins, manholes and drainage swales, and removal of accumulated sediment
within ten feet (10') of an inlet or outlet, provided there is no disturbance
to the original soil substrate. For purposes of § 9.6.3(A)(3) of this Part
a drainage swale is a conveyance that facilitates the drainage of stormwater
from paved or disturbed areas, but does not meet the definition of a river or a
stream; or
4. Repaving of, or
undertaking normal roadway maintenance of, paved public and private roadways or
bikeways, provided there is no expansion of these facilities. Normal roadway
maintenance includes: resurfacing and/or in-place recycling of paved surfaces;
repairs to, resetting or replacing curbs, berms, sidewalks or guardrails;
addition of guardrails, signing, striping or signals; adjusting manholes, catch
basins or utility structures to grade; structural repairs to, or in-place
replacement of manholes, catch basins or grates; and installation of wheel
chair ramps in existing sidewalks. Paving or oiling of dirt roads, however, is
considered an alteration which requires a permit; or
5. Repair to or maintenance of a stream
crossing, such as a stone ford and its approach, or any unpaved road which is
used at least on an annual basis, provided that any increase in road surface
cover does not require the expansion of any slopes further into the freshwater
wetland, buffer or floodplain beyond the present toe of slope, and provided
that any increase in height does not exceed two inches (2"). Repair or
maintenance to any stream crossing and its approach must be done during low or
no flow periods; or
6. Repair of
docks and foot bridges located outside of any area within two hundred feet
(200') of a coastal shoreline feature. This does not include enlargements or
extensions; or
7. Repair to boat
ramps which does not include enlargements, located outside of any area within
two hundred feet (200') of a coastal shoreline feature; or
8. Repair to any bridge or culvert, including
repair of cracks and spalling; sealing of joints; repointing of masonry;
replacement of decking with no replacement of other structural members or
increase in the deck width; repairs to or replacement of signage, railings, or
lighting; and painting located outside of any area within two-hundred feet
(200') of a coastal shoreline feature, provided that the repair does not
require vehicular equipment access beyond the existing road surface; no
permanent changes will occur in streambed geometry or hydraulic capacities; all
cleared or disturbed areas are allowed to revegetate; temporary cofferdams are
limited to placement of sand-bag/liner cofferdams or similar structures that
allow for unhindered flow in the remaining channel and do not require
disturbance of the substrate of any freshwater wetland or watercourse, and
provided that any material removed from the structure during repair is disposed
of properly; or
9. Removal of
manmade trash from a jurisdictional area that is not within a freshwater
wetland or buffer is exempt. Removal of manmade trash from freshwater wetlands,
buffers or floodplains without causing any change in their profile or general
character is also exempt, provided that the removal must be performed manually,
or by equipment when chains or cables can be attached to the item to be removed
and the equipment can be operated from a road, parking area, or other similar
location. Removal of natural material such as logs, brush, or trees from
freshwater wetlands, including flowing bodies of water or from buffers must be
limited to problem locations where lack of removal will result in erosion or
blockage of culverts, obstruction of existing paths, or prevention of canoeing
access; or
10. Repair to or
in-kind, in-place replacement of shoreline stabilization structures, excluding
those adjacent to tidal waters, such as stone and/or masonry walls provided
that there is no expansion of the structure and no material is placed in any
location or in any manner that would impair surface water flow, and no material
is placed in a manner such that it will be eroded by normal or expected high
surface water flows; or
11.
Maintenance of soil erosion and sediment control management practices and
stormwater management practices in accordance with a plan approved by the CRMC;
or
12. Maintenance of existing or
approved freshwater bathing beach that does not expand or otherwise change the
size or shape of the beach; or
13.
Inspection, maintenance and repair to those utility poles, structures,
equipment or underground lines or pipes which are necessary to provide utility
services to the public; or
14.
Replacement of utility poles, including changes in physical size, without any
change to existing or approved cleared rights of way; or
15. Repair and replacement of utility lines
attached to existing or approved bridges or in existing or approved roadways
and railway beds provided anti-seepage collars are used as appropriate to
prevent sub-draining effects on freshwater wetlands; or
16. Maintenance by municipalities of surface
water impoundments used for drinking water supplies, provided that all
maintenance activities occur within the existing boundary perimeters of the
impoundment and that the municipality provide the CRMC with twenty (20) days
advance written notice of such maintenance activity; or
17. Repair and replacement of wells and its
supply lines provided that the following conditions are met:
a. All cleared vegetation is allowed to
regrow naturally;
b. The volume of
withdrawal from the replacement well is no greater than five hundred (500)
gallons per day;
c. The
repair/replacement well will service the same lot as its predecessor;
d. No other feasible upland alternative is
available; and
e. All disturbances
to freshwater wetlands and buffer are limited to the maximum extent possible;
or
18. Repair of failed
onsite wastewater treatment system, made in accordance with the DEM's Rules
Establishing Minimum Standards Relating to Location, Design, Construction and
Maintenance of Onsite Wastewater Treatment Systems, 250-RICR- 150-10-6;
or
19. In-kind replacement of
existing or approved buildings and constructed property accessories if
destroyed by fire or natural causes; or
20. Repaving or undertaking normal
maintenance of existing parking lots where any pavement removal exposing
erodible soils is less than ten thousand (10,000) square feet in area;
or
21. Repair, replacement or
installation of gates, boulders, logs or other physical barriers intended to
limit unauthorized vehicular access to existing or approved driveways or access
roads, provided that the following conditions are met:
a. Such barriers extend along or beyond the
edge of the access road no farther than necessary to limit vehicular access;
and
b. No structural or material
barriers are placed in freshwater wetlands.
