VAN DER VAART Secretary S. JAY ZIMMERMAN Issuance of NPDES Permit NC0088188 Scenic Wolf Mountain WWTP Puncheon Fork Road, Mars Hill 28754 Madison County D;,Ycmr The Division of Water Resources (the Division) hereby issues the attached NPDES permit for the subject facility. This permit is issued pursuant to the requirements of North Carolina General Statute 143-215.1 and the Memorandum of Agreement between North Carolina and the U.S. Environmental Protection Agency dated October 15, 2007, or as subsequently amended. The Division understands that you have made no significant changes to your facility the last permit renewal. We have made the following updates to your previous permit: • updated the facility description (see supplement to cover sheet) and Map • added parameter codes to Section A. (1.) • added the limit for DO to the effluent table and removed footnote • added Electronic Reporting - Discharge Monitoring Reports page [Section A. (3.)]. Please be aware that in 2009, the entire Big Laurel Creek watershed (including Puncheon Creek) was reclassified to Outstanding Resource Waters (ORW). In accordance with 15A NCAC 2B.0225, the ORW stream classification does not allow for any new wastewater discharges or expansions of existing wastewater discharges. The renewed permit retains the provision for this facility to expand to an ultimate flow capacity of 0.3 MGD, but no additional expansions will be allowed beyond that volume. While the existing expansion provision is preserved in the permit, justification will have to be provided for the increase in design flow prior to approval of any expansion and the facilities to be constructed will have to demonstrate they will protect water quality standards associated with the ORW classification. Proposed federal regulations require electronic submittal of all discharge monitoring reports (DMRs) and specify that, if a state does not establish a system to receive such submittals, then permittees must submit DMRs electronically to the Environmental Protection Agency (EPA). The Division anticipates that these regulations will be adopted and is beginning implementation. The requirement to begin reporting discharge monitoring data electronically using the NC DWR's Electronic Discharge Monitoring Report (eDMR) internet application has been added to your NPDES permit.
