1、Designation: F 1231 89 (Reapproved 1999)Standard Guide forEcological Considerations for the Use of OilspillDispersants 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

Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This guide covers the use of oilspill dispersan
3、ts to assistin the 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
4、in spill response.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 gui
5、de only. It assumes 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
6、used in this guide, 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
7、dispersants primarily to protect habitatsfrom impact (or to minimize impacts) and to clean them aftera spill takes place.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
8、 decisions, appropriate govern-ment authorities should be consulted as required by law.01.7 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
9、 and determine the applica-bility of regulatory limitations prior to use.2. Significance and Use2.1 This guide is meant to aid local and regional responseteams who may use it during spill response planning and spillevents.2.2 This guide should be adapted to site-specific circum-stances.3.

They have adynamic near shore ecology, and a wide variety of animal andplant species. In northern regions, these water bodies may bepartly or completely ice covered dur

Commercially important fishing and recreational activi-ties are frequently associated with these water bodies.3.2 Rivers generally refer to large bodies of moving water,whereas creeks are smaller bodies of flo

Background4.1 The effects of oil and dispersed oil on these aquaticenvironments have been the subject of numerous st

Thestudies have involved both intentional experimental spills andstudies undertaken during actual spill situations (1-5).24.2 There have been a number of studies on the impact of oiland oil/dispersant mixtures on microbiological systems (6-16).4.3 The principal biotic components of such water

Terrestrial flora include grasses,m

In deep waterareas, there is little vegetation except for bacteria and algae(17-20).4.4 The fauna include invertebrates (zooplankton, molluscs,crustaceans, worms and other similar species), fish, a variety ofwaterfowl (ducks, loons, gulls, terns and hero

The distribution and composition of species isa function of climate, local geography and soil type, and humanuse of the area (21).4.5 Human activities range from recreation and tourism, toshipping and commercial fis

General Considerations for Making Dispersant UseDecisions5.1 The dispersant use decision is, in this case as mostothers, one of trade-offs. The use of dispersants can reduce theadverse ef

Recommendations6.1 Dispersant use in rivers and creeks and their borderingvegetation should be considered if a spill poses a significant-threat to indigenous wildlife or its habitat. In evaluating thepotential for dispersant use, consideration shou
22、ld 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 to a rivers andcreeks habitat, or a disruption of nesting and breeding activi-ties.6.2 The turbulence of the flowing water may b

In manycases the water is shallow enough that the dispersed oil willreach the bottom and will have the potential to cause impact onthe benthic community.6.3 The use of di
