1、Designation: F 1231 08Standard Guide forEcological Considerations for the Use of Oil SpillDispersants in Freshwater and Other Inland Environments,Rivers and Creeks1This standard is issued under the fixed designation F 1231; the number immediately following the designation indicates the year oforigin
2、al adoption or, in the case of revision, 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. Scope1.1 This guide covers the use of oil spill dispersants to assistin t
3、he control of oil spills. This guide is written with the goalof minimizing the environmental impacts of oil spills; this goalis the basis on which the recommendations are made.Aestheticand socioeconomic factors are not considered, although theseand other factors are often important in spill response
4、.1.2 Spill responders have available several means to controlor clean up spilled oil. In this guide, the use of dispersants isgiven equal consideration with other spill countermeasures. Itis not considered as “last resort” after all other methods havefailed.1.3 This is a general guide only. It assum
5、es the oil to bedispersible and the dispersant to be effective, available, appliedcorrectly, and in compliance with relevant government regula-tions. In the assessment of environmental sensitivity, it isassumed that the dispersant is nonpersistent in the naturalenvironment. Oil, as used in this guid
6、e, includes crude oils andrefined petroleum products. Differences between individualdispersants or between different oil products are not consid-ered.1.4 This guide is organized by habitat type, for example,small ponds and lakes, rivers and streams, and land. Itconsiders the use of dispersants prima
7、rily to protect habitatsfrom impact (or to minimize impacts).1.5 This guide applies only to freshwater and other inlandenvironments. It does not consider the direct application ofdispersants to subsurface waters.1.6 In making dispersant use decisions, appropriate govern-ment authorities should be co
8、nsulted as required by law.1.7 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations p

They have adynamic near-shore ecology and a wide variety of animal andplant species. In northern regions, these wat

Commercially important fishing and recreational activi-ties are frequently associated with these water bodies.4.2 Rivers generally refer to large bodies of m

16、ironments.5. Background5.1 The effects of oil and dispersed oil on these aquaticenvironments have been the subject of numerous studies. Thestudies have involved both intentional experimental spills andstudies undertaken during actual spill situations (1-2).35.2 There have been a number of studies on
17、 the impact of oiland oil/dispersant mixtures on microbiological systems (7-17)and freshwater biota (18, 19).5.3 The principal biotic components of such water bodiesare a variety of fauna and flora. The aquatic flora include algae(planktonic and attached) and floating or submerged vascularplants. Te
18、rrestrial flora include grasses, moss, lichens, herbs,forbs, and woody plants. In deep water areas, there is littlevegetation except for algae (20-23).5.4 The fauna include invertebrates (molluscs, crustaceans,worms and other similar species), fish, a variety of waterfowland seabirds (ducks, loons,
19、gulls, terns, and herons), mammals,such as beaver and muskrat, and in many areas, significanthuman activity. The distribution and composition of species isa function of climate, local geography and soil type, and humanuse of the area (24).5.5 Human activities range from recreation and tourism, toshi
20、pping and commercial fishing. In many cases, rivers andcreeks are the source of potable water for human consumptionand industrial use.6. General Considerations for Making Dispersant UseDecisions6.1 The dispersant use decision is, in this case as mostothers, one of trade-offs. The use of dispersants
21、can reduce theadverse effects of spilled oil on certain biological species at theexpense of other components of the ecosystem (25).6.2 Guide F 2532 should be followed before making adecision to use dispersants in a river or creek.6.3 In most cases, the mortality of individual creatures,while of conc
22、ern, is of less concern than the destruction ofhabitat. The repopulation of areas after the spill will occurnaturally when an area becomes a suitable habitat for a givenspecies.7. Recommendations7.1 Dispersant use in rivers and creeks and their borderingvegetation should be considered if a spill pos
23、es a significantthreat to indigenous wildlife or its habitat. In evaluating thepotential for dispersant use, consideration should be given tothe alternatives of leaving the oil untreated or the use ofmechanical recovery equipment. In many cases, a spill re-sponse operation can cause serious damage t
24、o a rivers andcreeks habitat, or a disruption of nesting and breeding activi-ties.7.2 The turbulence of the flowing water may be adequate toprovide the energy for dispersion and vertical transport. This iscertainly the case in areas where there are rapids. In manycases, the water is shallow enough t
