The same limits are recommended for this permitting cycle. The facility states that pentachlorophenol (PCP) and trichlorophenol (TCP) are not used in their processing; an updated certification letter is required. TSB recommends that the facility continue to state within their DMR that those compounds are not used. Limits will be recommended within the permit; however, monitoring will not be required if a statement is made within the DMR that those compounds are not used (as was previously recommended). A model was performed that included Happy Valley Elementary, Skill Craft Enterprise, and Sealed Air. The model predicted no violation in D.O. at the current loading. Existing limits will be recommended. DMR data indicate no violations. Total residual chlorine monitoring was recommended previously due to the potential impact to trout waters by PCP and TCP. Chlorine has been reported below detection level for the past 2 years. TSB recommends chlorine onlbly be monitored if TCP and PCP are used (not required in the effluent guidelines). Sealed Air has passed its toxicity testing requirement for the past 4 years. All limitations are subject to change when the Yadkin River Basin management plan is in place.

Other Special Items: PART IV - iVALUATION AND RECOMMENDATIONS Sealed Air Corporation maintains NPDES Permit Number NC0006254 which includes outfall 001 for process wastewater and a small amount of domestic wastewater and outfall 002 for non -contact cooling water. The facility began using some brown paper as a raw material in January. This change is concurrent with an accumulation of solids in the fiber trap and carrying through into the polishing pond. It is not known if these are related. It is recommended that the permit be renewed as requested. buitfce, Signature of Report Preparer D 1 ater ,.ia,,3,ity Regional Supervisor 1/(// Page 4 0 i•• • )• `17 t. :. rl ,l / .4T •f •' 1.J.• A' --1 C' L • 3 .‘ "I I-- ›.:;,.s ,--.1 170 r J• • •1C✓J t; { 1• -• .FYI-• - •( ' .
