Construction is to be performed in accordance with this permit and supporting engineering report, plans, and specifications approved by this Office. This system cannot be placed into operation until final approval is granted by the appropriate Bureau of Environmental Health Services (BEHS) Regional Office. Your Regional contact is Kristen L Jones, in the MIDLANDS REGION BEHS LANCASTER. This regional office should be notified when construction begins at the following address and phone number: 2475 DHEC RD, LANCASTER SC 29720, 803-285-7461. Upon completion of any construction, a letter must be submitted to the BEHS Regional Office from the registered engineer certifying that the construction has been completed in accordance with the approved plans and specifications. An inspection may then be scheduled. The BEHS Regional Office will approve the system for operation upon successful completion of this project.

Registration Number: 19829. PROJECT DESCRIPTION: Modification of the existing Equalization (EQ) Basin and Sludge Dewatering system. See Page 2. The effluent will be discharged to the Catawba River at a daily average rate of 25,000,000 (no new flow) gallons per day. The effluent concentrations of those constituents the wastewater treatment system is designed to remove or reduce are contained in NPDES Permit #SC0001015. CONDITIONS: See page 3. In accepting this permit, the owner agrees to the admission of properly authorized persons at all reasonable hours for the purpose of sampling and inspection. This is a permit for construction only and does not constitute DHEC approval, temporary or otherwise, to place the system in operation. An Approval to Place in Operation is required and can be obtained following the completion of construction by contacting the LANCASTER EQC OFFICE at 803-285-7461. Additional permits may be required prior to construction (e.g., Stormwater).
