PART C-If you are a primary industry and this outfall contains process wastewater,refer to Table 2c-2 in the instructions to determine which of the GC/MS fractions you must test for.Mark"X"in
column 2-a for all such GC/MS fractions that apply to your industry and for ALL toxic metals,cyanides,and total phenols.If you are not required to mark column 2-a(secondary industries,
nonprocess wastewater outfalls,and nonrequired GC/MS fractions),mark"X"in column 2-b for each pollutant you know or have reason to believe is present.Mark"X"in column 2-c for each
pollutant you believe is absent. If you mark column 2a for any pollutant,you must provide the results of at least one analysis for that pollutant.If you mark column 2b for any pollutant,you
must provide the results of at least one analysis for that pollutant if you know or have reason to believe it will be discharged in concentrations of 10 ppb or greater.If you mark column 2b for
acrolein,acrylonitrile,2,4 dinitrophenol,or 2-methyl-4,6 dinitrophenol,you must provide the results of at least one analysis for each of these pollutants which you know or have reason to
believe that you discharge in concentrations of 100 ppb or greater.Otherwise,for pollutants for which you mark column 2b,you must either submit at least one analysis or briefly describe the
reasons the pollutant is expected to be discharged.Note that there are 7 pages to this part;please review each carefully.Complete one table(all 7 pages)for each outfall.See instructions
