(1) This general permit authorizes the
following activities:
(a) Activities required
for the construction, maintenance, repair, and removal of utility lines and
associated facilities in state-assumed waters, provided the activity does not
result in the loss of greater than 1/2-acre of state-assumed waters for each
single and complete project.
1. A "utility
line" is defined as any pipe or pipeline for the transportation of any gaseous,
liquid, liquescent, or slurry substance, for any purpose, and any cable, line,
or wire for the transmission for any purpose of electrical energy, telephone,
and telegraph messages, and internet, radio, and television communication. The
term "utility line" does not include activities that drain a state-assumed
water, such as drainage tile or French drains, but it does apply to pipes
conveying drainage from another area.
2. Material resulting from trench excavation
may be temporarily sidecast into state-assumed waters for no more than three
months, provided the material is not placed in such a manner that it is
dispersed by stormwater or other forces. The Agency may extend the period of
temporary side casting for no more than a total of 180 days, where appropriate.
For a trench with a top width greater than three feet in herbaceous wetlands,
the upper layer of the soil horizon shall initially be scraped and segregated
into a spoil bank that is separated from the spoil bank resulting from the
excavation of the trench for the utility line. The upper layer of the soil
horizon shall be replaced as the last step of restored grades to facilitate
natural revegetation. The trench cannot be constructed or backfilled in such a
manner as to drain state-assumed waters (e.g., backfilling with extensive
gravel layers, creating a French drain effect).
3. Any exposed slopes and stream banks must
be stabilized immediately upon completion of the utility line crossing of each
waterbody.
4. For overhead utility
lines authorized by this general permit, a copy of the notice will be provided
to the Department of Defense Siting Clearinghouse, which will evaluate
potential effects on military activities.
(b) Construction, maintenance, or expansion
of substation facilities associated with a power line or utility line in
state-assumed waters, provided the activity, in combination with all other
activities included in one single and complete project, does not result in the
loss of greater than 1/2-acre of state-assumed waters.
(c) Construction or maintenance of
foundations for overhead utility line towers, poles, and anchors in
state-assumed waters, provided the foundations are the minimum size necessary
and separate footings for each tower leg (rather than a larger single pad) are
used where feasible.
(d)
Construction of access roads for the construction and maintenance of utility
lines, including overhead power lines and utility line substations, in
state-assumed waters, provided the activity, in combination with all other
activities included in one single and complete project, does not cause the loss
of greater than 1/2-acre of state-assumed waters.
1. Access roads must be the minimum width
necessary.
2. Access roads must be
constructed so that the length of the road minimizes any adverse effects on
state-assumed waters and must be as near as possible to pre-construction
contours and elevations (e.g., at grade corduroy roads or geotextile/gravel
roads). Access roads constructed above pre-construction contours and elevations
in state-assumed waters must be properly bridged or culverted to maintain
surface flows.
3. Access roads used
for both construction and maintenance may be authorized, provided they meet the
terms and conditions of this general permit.
4. Access roads used solely for construction
of the utility line must be removed upon completion of the work, in accordance
with the requirements for temporary fills as referenced in paragraph (f),
below.
(e) Temporary
structures, fills, and work necessary for the remediation of inadvertent
returns of drilling fluids to state-assumed waters through sub-soil fissures or
fractures that might occur during horizontal directional drilling activities
conducted for the purpose of installing or replacing utility lines.
1. These remediation activities must be done
as soon as practicable, to restore the affected waterbody.
2. Permittees must prepare a frac-out plan
prior to construction that meets the requirements of section 3.2.1.3 of the 404
Handbook.
(f) Temporary
structures, fills, and work, including the use of temporary mats, necessary to
conduct the utility line activity.
1.
Appropriate measures must be taken to maintain normal downstream flows and
minimize flooding to the maximum extent practicable, when temporary structures,
work, and fill, including cofferdams, are necessary for construction
activities, access fills, or dewatering of construction sites.
2. Temporary fills must consist of materials,
and be placed in a manner, that will not be eroded by expected high flows or
stormwater.
3. After construction,
temporary fills must be removed in their entirety and the affected areas
returned to pre-construction elevations.
4. The areas affected by temporary fills must
be revegetated.
(3) A notice of
intent to use this general permit is required prior to commencing the activity
if any of the following criteria are met:
(a)
The activity involves mechanized land clearing in a forested wetland for the
utility line right-of-way.
(b) The
utility line in state-assumed waters, excluding overhead lines, exceeds 500
feet.
(c) The utility line is
placed within a state-assumed water, and it runs parallel to or along a stream
bed that is within that area of state-assumed waters.
(d) Activities that result in the loss of
greater than 1/10-acre of state-assumed waters.
(e) The activity is within forested
wetlands.
(f) Permanent access
roads are constructed above grade in state-assumed waters for a distance of
more than 500 feet.
(g) Permanent
access roads are constructed in state-assumed waters with impervious
materials.
(h) The project is in
the following rivers, creeks, and their tributaries:
1. Escambia River
2. Yellow River
3. Shoal River
4. Choctawhatchee River
5. Chipola River
6. Apalachicola River
7. Ochlockonee River
8. Santa Fe River
9. New River (Bradford and Union County
line)
10. Econfina
Creek.
