Table 5. A Framework for Ecological Impact Assessment 



Sequential Steps 



Step 1 . Analyze Proposed Work Plan 



Review and analyze permit applications and 

 accompanying information to determine the 

 exact nature and the stages of work: 



Identify subprojects (primary 



and secondary) and their relevant 

 design features. 



Identify activities and their rele- 

 vant construction methods and operating 

 characteristics. 



Step 2. Select Activities with Potential for 



Significant Disturbance 



Check the activities in Step 1 for probable 

 generation of significant disturbance ; 

 select for analysis (in Step 3) those with 

 apparent disturbance potential : 



Screen identified activities for 

 potential disturbance to fish and 

 wildlife and habitats. 



Select for analysis those with 



potential for significant disturbance . 



Step 3. Analyze Potential Disturbance 



Consider each activity selected for 

 analysis by the following sequence: 



Activity: Description and sources 

 of disturbance . 



Disturbances: Description and 



sources of adverse (or beneficial) 

 effects.
