ommendation can be made concerning the items 2, 3, and 4 above with- 

 out enumerating the definitive characteristics of each water body. This 

 hopefully will be accomplished by a monitoring program with sufficient 

 sampling locations and with sufficient frequency to describe the system 

 within reasonable confidence limits. 



It is realized that any monitoring program designed to meet what 

 are present, and as well as can be predicted, future needs may recjuire 

 modification from time to time. It is, therefore, obvious that periodic 

 examination must be given to monitoring specifications to insure their 

 continuing adequacy and to remove redundancy. 



Monitoring waste discharges 



It was concluded that specifications should be developed for a mini- 

 mum or core-type monitoring program that should be applied to all 

 "significant" waste discharges. "Significant" waste discharges are not 

 defined herein ; but they are to be defined as part of the recommended 

 research and development program. However, they are considered here 

 to include but not necessarily be limited to the following candidate 

 waste materials : 



(1) Municipal and industrial waste streams; 



(2) Storm runoff and combined sewer overflows ; 



(3) Water courses containing significant waste materials; and 



(4) Batch waste dumping and barging operations. 



It should be recognized at the outset that it is both logical and likely 

 that all waste discharges, especially minor ones such as the treated 

 strictly domestic wastes from 100 persons discharging into open coastal 

 waters, would not be classified as "significant." On the other hand, it 

 should be recognized that many major waste discharges will require 

 many more analyses than the core minimum program to characterize 

 properly the waste discharge characteristics. 



(1) Objectives. — The general objective of the core waste discharge 

 monitoring program is to provide the minimum information needed 

 to assess adequately the pollutional contribution of waste materials to 

 the Nation's coastal environment. Specific objectives would include but 

 not necessarily be limited to the f olloAving : 



{a) To provide quantitative information on the unit and total 

 mass emission rates for the common significant groups of j)ollut- 

 ants from significant waste-generating activity such as municipal, 

 industrial, agricultural, natural, and other sources so that: 



[1] Adequate data are available for forecasting future 

 waste contributions based upon the level of future estimated 

 waste-generating activity (population, industrial production, 

 etc.) ; 



[2] Accurate input data are available for use in various 

 modeling systems to provide estimates of waste concentra- 

 tions and their variation in space and time ; and 



[3] It is possible to attempt to correlate or develop func- 

 tional relationships between waste emission rates and waste 

 effects which are principally biological in character. 

 {b) To assess performance on a gross basis of waste treatment 

 installations. 



(c) To insure that adequate information is available to permit
