Louisiana Administrative Code › Title 43 - NATURAL RESOURCES › Part I - Office of the Secretary › Subpart 1 - General › Chapter 7 - Coastal Management › Subchapter B - Coastal Use Guidelines › Section I-705 - Guidelines for Linear Facilities

Current through Register Vol. 50, No. 6, June 20, 2024
A.
					 Linear use alignments shall be planned to avoid adverse impacts on areas of
					 high biological productivity or irreplaceable resource areas.
B. Linear facilities involving the use of
					 dredging or filling shall be avoided in wetland and estuarine areas to the
					 maximum extent practicable.
C.
					 Linear facilities involving dredging shall be of the minimum practical size and
					 length.
D. To the maximum extent
					 practicable, pipelines shall be installed through the "push ditch" method and
					 the ditch backfilled.
E. Existing
					 corridors, rights-of-way, canals, and streams shall be utilized to the maximum
					 extent practicable for linear facilities.
F. Linear facilities and alignments shall be,
					 to the maximum extent practicable, designed and constructed to permit multiple
					 uses consistent with the nature of the facility.
G. Linear facilities involving dredging shall
					 not traverse or adversely affect any barrier island.
H. Linear facilities involving dredging shall
					 not traverse beaches, tidal passes, protective reefs, or other natural gulf
					 shoreline unless no other alternative exists. If a beach, tidal pass, reef, or
					 other natural gulf shoreline must be traversed for a non-navigation canal, they
					 shall be restored at least to their natural condition immediately upon
					 completion of construction. Tidal passes shall not be permanently widened or
					 deepened except when necessary to conduct the use. The best available
					 restoration techniques which improve the traversed area's ability to serve as a
					 shoreline shall be used.
I. Linear
					 facilities shall be planned, designed, located, and built using the best
					 practical techniques to minimize disruption of natural hydrologic and sediment
					 transport patterns, sheet flow, and water quality and to minimize adverse
					 impacts on wetlands.
J. Linear
					 facilities shall be planned, designed, and built using the best practical
					 techniques to prevent bank slumping and erosion, and saltwater intrusion, and
					 to minimize the potential for inland movement of storm-generated surges.
					 Consideration shall be given to the use of locks in navigation canals and
					 channels which connect more saline areas with fresher areas.
K. All nonnavigation canals, channels, and
					 ditches which connect more saline areas with fresher areas shall be plugged at
					 all waterway crossings and at intervals between crossings in order to
					 compartmentalize them. The plugs shall be properly maintained.
L. The multiple use of existing canals,
					 directional drilling, and other practical techniques shall be utilized to the
					 maximum extent practicable to minimize the number and size of access canals, to
					 minimize changes of natural systems, and to minimize adverse impacts on natural
					 areas and wildlife and fisheries habitat.
M. All pipelines shall be constructed in
					 accordance with Parts 191, 192, and 195 of Title 49 of the Code of Federal
					 Regulations, as amended, and in conformance with the Commissioner of
					 Conservation's Pipeline Safety Rules and Regulations and those safety
					 requirements established by R.S. 45:408, whichever would require higher
					 standards.
N. Areas dredged for
					 linear facilities shall be backfilled or otherwise restored to the pre-existing
					 conditions upon cessation of use for navigation purposes to the maximum extent
					 practicable.
O. The best practical
					 techniques for site restoration and revegetation shall be utilized for all
					 linear facilities.
P. Confined and
					 dead end canals shall be avoided to the maximum extent practicable. Approved
					 canals must be designed and constructed using the best practical techniques to
					 avoid water stagnation and eutrophication.
