2、, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1.

This guide provides a template for that purpose.4.2 Data on oiling conditions at a shoreline are needed toprovi

Data on oiling conditions would be used inassessing the need for cleanup actions, selecting the mostappropriate response technique(s), determining priorities forclean

The magnitude and type of datasets collected may likewise vary with the nature of the spill andoperational needs.5,64.4 Consistent data se

17、ts (observations and measurements)on shoreline oiling conditions are essential within any one spillin order to compare the data between different sites orobservers, and to compare the data against existing bench-marks or criteria that have been developed to rate the nature orseverity of the oiling.

18、To the extent possible, consistency is alsodesirable between different spills, in order to benefit fromprevious experiences and cleanup decisions.4.5 It is recognized that some modifications may be appro-priate based on local or regional geographic conditions or uponthe specific character of the str

19、anded oil.5. General Considerations5.1 Shoreline conditions can be described in terms of thelength, width, depth, distribution, quantity, and character of oilcontamination. These six different types of data are collectedby direct measurement or direct visual estimates calibratedagainst existing scal

20、es or indices. Standard definitions anddescriptors of these data have been developed (Sections 6 and7). Second-order applications of the basic data are further usedto aid response planning (Sections 8 and 9).5.2 Descriptions of shoreline oiling conditions are typicallyreferenced to the lateral (seaw

21、ard to landward) shorelinezonation. The location of the stranded oil within the intertidalzone affects operational access time and oil persistence.5.2.1 Tidal zonation is described in terms of the supra-tidal,upper/mid/lower intertidal, and sub-tidal zones.5.2.2 Non-tidal shoreline zonation is descr

22、ibed in terms ofthe supra/upper/lower swash zone for lacustrine (lake) envi-ronments and the over/upper/lower/midstream bank for river-ine (river) environments.5.3 Oil persistence and the choice of cleanup options will bedifferent for subsurface oil as opposed to surface oil. Descrip-tions of shorel

23、ine oiling conditions should distinguish betweenthe oiling of surface sediments from that on the subsurfacesediments (vertical zonation). On coarse sediment beaches, itcan be difficult to differentiate the vertical boundaries. Fig. 1illustrates an approach for discriminating those boundaries.5.4 For

24、 beaches with fine sediments (that is, pebble, gran-ule, sand, and mud), the subsurface begins at 5 cm below thesurface. If a pit were to reveal oiling in sand from the surfacedown to 20 cm, the upper 5 cm would be classified as surfaceoil and the remainder as subsurface. However, the oiledinterval

25、would still be shown as 0 to 20 cm.5.5 For beaches with coarse sediments (that is, cobble andboulder), the subsurface begins at the bottom of the surfacematerial (that is, where the top layer of cobbles or boulderscontact the underlying layer of sediments).5.6 Where asphalt pavement exists on the su

26、rface, thesubsurface begins at the bottom of the pavement.5.7 Definitions of the inorganic sediments based on size areas follows:Boulder (256-mm diameter)Cobble (64 to 256-mm diameter)Pebble (4 to 64-mm diameter)Granule (2 to 4-mm diameter)Sand (0.06 to 2-mm diameter)Mud/silt/clay (6 mMedium 3 to #6

27、mNarrow 0.5 to #3mVery narrow #0.5 m6.2.3.2 Areas of micro-tidal (for example, Great Lakes) ormacro-tidal (for example, Bay of Fundy or Cook Inlet)exposure will require an adjustment based on the width of theshoreline.6.3 Oil DistributionThis refers to the percentage of theshoreline surface sediment

28、s that are covered with oil, within afixed area.6.3.1 In the event of multiple bands, distribution refers tothe estimated percentage that best represents the collectivearea.6.3.2 Distribution should be described by the percentagevalue that was observed.6.3.3 Where a descriptive expression is require
