1.3.6 Evaluation of Effects. 



(a) General. The evaluation of the effects of each 

 alternative plan consists of assessment and ap- 

 praisal. 



(b) Assessment. Assessment is the process of 

 measuring or estimating the effects of an alterna- 

 tive plan. Assessment determines the difference 

 between without-plan and with-plan conditions for 

 each of the categories of effects. 



(c) Appraisal. 



(1) Appraisal is the process of assigning social 

 values to the technical information gathered as part 

 of the assessment process. 



(2) Since technical data concerning benefits and 

 costs in the NED account are expressed in mone- 

 tary units, the NED account already contains a 

 weighting of effects; therefore, appraisal is applica- 

 ble only to the EQ, RED, and OSE evaluations. 



(d) Displays. The results of the evaluation should 

 be displayed according to the directions provided in 

 Section VIII— Displays. 



1.3.7 Comparison of Alternative Plans. 



(a) The comparison of plans focuses on the dif- 

 ferences among the alternative plans as deter- 

 mined in the evaluation phase. 



(b) The differences should be organized on the 

 basis of the effects in the four accounts or on a 

 combination of the NED account and another ap- 

 propriate format for other significant effects. 



1.3.8 Plan Selection. 



After consideration of the various alternative 

 plans, their effects, and public comments, a plan is 

 selected following the general guidance in Section 

 X— Plan Selection. 



Section IV— General Planning 

 Considerations 



1.4.1 Federal-State Relationship in Planning. 



(a) The responsible Federal planning agency is to 

 contact the Governor or designated agency for 

 each affected State before initiating a study and 

 enter into such agreements as are appropriate to 

 carry out a coordinated planning effort. 



(b) The State agency or agencies responsible for 

 or concerned with water planning are to be pro- 

 vided with appropriate opportunities to participate in 



defining the problems and opportunities, in scoping 

 the study, and in review and consultation. 



1.4.2 International Consultations. 



When a Federal water project is likely to have a 

 significant impact on any land or resources situated 

 in a foreign country or to affect treaty obligations, 

 the responsible Federal planning agency, through 

 the Department of State, should enter into consul- 

 tations with the government of the affected country, 

 with a view to determining the international implica- 

 tions of the project under consideration. 



1.4.3 General Public Participation. 



(a) Interested and affected agencies, groups, and 

 individuals should be provided opportunities to par- 

 ticipate throughout the planning process. The re- 

 sponsible Federal planning agency should contact 

 and solicit participation of: other Federal agencies; 

 appropriate regional. State, and local agencies; na- 

 tional, regional and local groups; other appropriate 

 groups such as affected Indian tribes; and individ- 

 uals. A coordinated public participation program 

 should be established with willing agencies and 

 groups. 



(b) Efforts to secure public participation should 

 be pursued through appropriate means such as 

 public hearings, public meetings, workshops, infor- 

 mation programs, and citizen committees. 



1.4.4 Review and Consultation. 



Review and consultation with interested and af- 

 fected agencies, groups, and individuals are 

 needed in the planning process. Reviews are to be 

 consistent with the requirements of applicable Fed- 

 eral statutes and the CEQ NEPA regulations (40 

 CFR Parts 1500-1508). The planning process de- 

 scribed in these Guidelines and the CEQ and NEPA 

 regulations are complementary. 



1.4.5 Interdisciplinary Planning. 



An interdisciplinary approach should be used in 

 planning to ensure the integrated use of the natural 

 and social sciences and the environmental design 

 arts. The disciplines of the planners should be ap- 

 propriate to the issues identified in the scoping 

 process. The planning agency should supplement 

 Its available expertise, as necessary, with knowl- 

 edgeable experts from cooperating agencies, uni- 

 versities, consultants, etc.
