Primary frontal dune definition

Primary frontal dune means a continuous or nearly continuous mound or ridge of sand with relatively steep seaward and landward slopes immediately landward and adjacent to the beach and subject to erosion and overtopping from high tides and waves during major coastal storms. The inland limit of the primary frontal dune occurs at the point where there is a distinct change from a relatively steep slope to a relatively mild slope.

More Definitions of Primary frontal dune

Primary frontal dune means a continuous or nearly continuous mound or ridge of sand with relatively steep seaward and landward slopes immediately landward and adjacent to the beach and subject to erosion and overtopping from high tides and waves during major coastal storms. The inland limit of the primary frontal dune occurs at the point where there is a distinct change from a relatively steep slope to a relatively mild slope.” Figure 1, taken from the May 6, 1988 Federal Register, illustrates the Primary Frontal Dune limit described above. 44 CFR subsection 60.3(e)(7) of the NFIP regulations requires that participating communities prohibit manmade alterations of sand dunes in VE Zones which would increase potential flood damage. Thus, expansion of a VE Zone via the PFD expands the dune areas protected by 60.3(e)(7).

FEMA also included a new section in 44 CFR Part 65, requiring that the storm-induced erosion cross-sectional area of 540 square feet serve as the basic criterion to be used in evaluating whether a primary frontal dune will act as an effective barrier during the 1-percent-annual- chance flood (see Event-Based Erosion report, Topic 37). The guidance in Appendix D for primary frontal dunes as it pertains to 44 CFR Parts 59, 60,and 65 described above, needs some clarification (which is addressed in some detail in Critical Topic

  • Best available control technology (BACT means an emissions limitation (including a visible emission standard) based on the maximum degree of reduction for each pollutant subject to regulation under CAA which would be emitted from any proposed major stationary source or major modification which the Department, on a case-by-case basis, takes into account energy, environmental, and economic impacts and other costs, determines is achievable for such source or modification through application of production processes or available methods, systems, and techniques, including fuel cleaning or treatment or innovative fuel combustion techniques for control of such pollutant. In no event shall application of best available control technology result in emissions of any pollutant which would exceed the emissions allowed by any applicable standard under 7 DE Admin. Code 1120 and 1121. If the Department determines that technological or economic limitations on the application of measurement methodology to a particular emissions unit would make the imposition of an emissions standard infeasible, a design, equipment, work practice, operational standard, or combination thereof, may be prescribed instead to satisfy the requirement for the application of best available control technology. Such standard shall, to the degree possible, set forth the emissions reduction achievable by implementation of such design, equipment, work practice or operation, and shall provide for compliance by means which achieve equivalent results.
