(2) effluent page. This permit modification corrects the following items: ➢ Total Suspended Solids must be monitored at the influent as well as the effluent in order to verify 85% removal at the effluent. > Conductivity monitoring should be a grab sample. ➢ Instream samples should be collected once per week in January -May and October -December. Please find enclosed the revised permit page. The revised page should be inserted into your permit. The old page may then be discarded. All other terms and conditions contained in the original permit remain unchanged and in full effect. This permit modification is issued under the requirements of North Carolina General Statutes 143- 215.1 and the Memorandum of Agreement between North Carolina and the U. S.

Rutherfordton is one that Jeff drafted and that I ended up finishing. I'll send out a modification this week. Rob - ditto on the errors you found. Thanks to you both for catching these.
