19、687, and F2204as well as the other referenced publications the referenced publications and ASTM guides to make informed decisions prior toundertaking cleaning operations. Consult appropriate government agencies according to law.3.3 The relative sensitivities of shorelines and resources relate to a n

Description and Relative Sensitivity

21、of Shorelines4.1 This section summarizes the types of shorelines and habitats that may be impacted by an oil spill. The EnvironmentalSensitivity Index (ESI) is frequently used to characterize relative sensitivity of shorelines to oil spills. Areas exposed to high levelsof physical energy and contain

22、ing low biological activity would rank low (ESI=1, example: exposed rocky shores). Sheltered areaswith associated high biological activity have the highest ranking (ESI=10, example: mangroves). Broad guidelines are providedon preferred strategies for cleaning these shorelines following an oil spill

23、incident.4.2 Exposed Rocky ShoresAlso known as exposed wave-cut cliffs. The inter-tidalintertidal zone is steep (more than 30-45 30to 45 slope) and narrow with little width. Access can be difficult and dangerous. Sediment accumulation is uncommon and usuallytransitory because waves remove the debris

24、 from the eroding cliffs. There is strong vertical zonation of inter-tidalintertidalbiological communities. Species density and diversity vary greatly but can be abundant. Oil would generally be held offshore byreflection of the waves. However, pockets of stranded oil can occur. Any oil that is depo

25、sited would be rapidly removed naturally.Cleanup is usually not required.4.3 Exposed Man-made StructuresThese are solid structures such as seawalls, piers, and port facilities. They are common indeveloped areas, providing protection to residential and industrial zones. Many structures are constructe

26、d of concrete, wood, stone,or metal. They are built to protect from erosion by waves, boat wakes, and currents. They are exposed to rapid natural removalprocesses. Attached animals and plants are sparse to moderate. Oil would be held offshore by waves reflecting off the steep, hardsurfaces in expose

27、d settings. Cleanup may not be required. All cleanup techniques may be appropriate including surface-washingagents.4.4 Exposed Wave-Cut PlatformsPlatforms and Sheltered Bedrock HabitatsThese shoreshabitats are characterized by gentlysloping bedrock shelves, called platforms, of highly variable width

28、. A steep scarp or low bluff may back the shoreline. They oftenco-occur with gravel beaches. The platform surface is irregular and cracks, crevices, and tidal pools are common. Smallaccumulations of gravel can be found in the tidal pools and crevices in the platform. PocketsAreas of sandy “tidal fla

29、ts” veneercan occur on the platform in less exposed settings. These habitats can support large populations of encrusting animals and plants,including barnacles, snails, mussels, and macroalgae. Birds and seals use platforms for feeding and resting during low tide. Oildoes not adhere to the wet surfa

If the area is accessible, it may be feasible to manually remove heavy oilaccumulations and oiled debris.4.5 Sand BeachesHabitatsBeaches Sand habitats a

31、re generally flat to moderately sloping and relatively hard-packed. TheySand habitats include sand bars and banks along rivers. In developed areas, sand habitats can be man-made for the purpose ofrecreation. In exposed coastal areas, they are commonly backed by dunes or seawalls along exposed outer

32、coasts. seawalls. Therecan be heavy accumulations of wrack (remnants of stranded marine vegetation or wrecked ships) or other debris. Beaches Sandhabitats can undergo rapid erosion/deposition cycles as currents and storms relocate the sand. Sand habitats have low to mediumsensitivity. In developed a

33、reas, sand habitats used as recreational beaches are considered sensitive for economic reasons. Biologicalpopulations are typically of low density. Birds use beaches density except if the habitat is in a protected area and contains muddysediments. Birds use sand habitats for resting, feeding, and ne

34、sting. Marine turtles use beaches Turtles use these habitats to lay theireggs. Oil penetration can be as much as 15 cm in fine- to medium-grain sand and up to 30 cm in coarse-grain sand. Cleanup shouldconcentrate on manually removing persistent oil and oily debris manually from the upper swash zone.

35、debris. On recreationalbeaches, extensive cleanup is required. Replacement with clean sand having the appropriate composition, grain-size, and color maybe necessary if large amounts of sand are removed during cleanup.4.6 Tundra CliffsThese shorelines are found in extremely cold regions near permafro

36、st areas. They are generally comprisedof vegetation overlying peat and permafrost. The cliff height ranges from less than 1 metermetre to as much as 10 meters.metres.The vegetation on the tundra is a living plant community that is sensitive to disturbance. The main users of this shoreline aremigrato

37、ry birds during the summer season and they are most at risk by oiling. Oil can be removed by sorbing with natural peatfrom beach deposits by sorbents or by manual and mechanical methods as long as there is no damage to the peat substrate. Accessmay be limited due to fragility of tundra vegetation.F2

38、464 1224.7 Mixed Sand and Gravel BeachesHabitatsThese moderately sloping beacheshabitats contain significant (over 25 %each) amounts of both sand and gravel. The high-tide berm area is usually composed of sand and fine gravel and the lower partof the beach is coarser with cobbles to boulders. In gla

39、ciated areas, large boulders may occur. Mixed sand and gravel habitats occuralong lakes and as bars along rivers and streams. There can be large-scale changes in the sediment distribution patterns dependingupon season, because of the transport of sand offshore during storms. Desiccation and sediment

40、 mobility on exposed beachesareasresult in low densities of attached animals and plants. The presence of algae, mussels, and barnacles indicates beaches indicatecoastal habitats that are relatively sheltered. Oil penetration into the beach sediments may be up to 50 cm. In freshwater areas,worms and

41、insects such as mayflies, caddisflies, and midges may burrow in mixed sand and gravel habitats. This habitat mayinclude fish spawning areas, birds, and mammals. Oil penetration and sediment deposition can result in subsurface oil layers atdepths of over a metre. If the sand fraction exceeds 40 %, oi

All oiled debris should beremoved; sediment removal should be limited as much as possible. Movement possible as erosion is a concern. In c

43、oastal areas,relocation of oiled sediment from high-tide zones to upper inter-tidalintertidal zones can be effective in areas regularly exposedto wave activity.4.8 Gravel BeachesHabitatsThese beacheshabitats are composed of substrate ranging in size from pebbles to boulders.They can be very steep, w

Density of animals and plants in the upperinter-tidalintertidal zone is low on exposed beaches,habitats, but can be high on sheltered gravel beacheshabitats and on the lowerinter-tidal zone. intertidal zone. Gravel habitats occur along lakes and

45、 as bars along rivers and streams. In freshwater areas,biological communities are of low density. Adult insects and larvae (mayflies, stoneflies, caddisflies, and midges) live among thegravel. Flatworms, leeches, and crustaceans also occur. Fish spawning areas may occur in this habitat. Stranded oil

All oiled debris should be removed. Substrate removal should be limitedas much as possible. possible due to

47、 the slow rate of natural replenishment in freshwater areas.4.9 Vegetated Shoreline HabitatsThese habitats occur in non-wetland banks of rivers and lakes. The slopes of these habitatsmay be gentle or steep. Characteristic vegetation include grasses, bushes, and trees. Leaf litter and woody debris ca

48、n be trappedamong the vegetation. Lawns and gardens may occur along a river or lake in developed areas. Sediments range from clay to gravel.Seasonal flooding may occur along the banks with high-energy removal conditions. Many species of animals use vegetated banksas important habitats. Oil can penet

49、rate sediments and contact root systems. On gentle banks, oil may contaminate large areas ofvegetation. Various cleanup methods may be appropriate such as vacuuming, sorbent use, low-pressure flushing, removal of oilydebris, use of surface-washing agents, burning, and cutting of oiled vegetation.4.10 Freshwater Mud HabitatsMud habitats occur along river floodplains and lake bottoms that are exposed during seasonallow water levels. These habitats are typically found in low-energy areas and often associated with wetlands. This habitat is oftena natural collect
