(4) Supplemental information ; 



(a) Information on the accuracy and precision of both 

 the sampling and analytical methods is to be obtained 

 and reported. 



(b) Data should be obtained on the level of waste- 

 generating activity (i.e., for municipal waste - popu- 

 lation tributary; for industrial wastes, level of pro- 

 duction and type - tons of product/ day, etc.) so that 



waste discharges can be reported on a unit mass emis- 



3 

 sion rate basis (i.e., lbs SS/capita-day or lbs SS/10 



lbs product) 



(5) Significant discharge : It should be noted that the 

 recommended minimum monitoring program is, as stated, the 

 minimum to be applied to all "significant" waste discharges. 

 Many significant waste discharges may require numerous addi- 

 tional characteristics or parameters to be added to the 

 minimum listing to describe properly the waste
