Dear Mr. Neville:
John E. Skvarla, 111
Secretary
Subject: Draft NPDES Permit
NC0086894
Robeson County Water Department
Ramon Well Water Treatment Plant (WTP)•
Robeson County
In response to your request to renew the subject NPDES permit, the Division of Water Resources (DWR or the
Division) hereby transmits this draft for your review and comment. Please review this document to assure your
understanding of the permit limits and monitoring conditions, and to correct errors, if any.
The changes between this draft permit and the previous permit include the following:
• In accordance with the NPDES Permitting Strategy for WTP's (2009), facilities discharging greater than
50,000 gpd are required to install a continuous recorder to monitor wastewater discharge flows. As a
result, continuous flow monitoring has been added to your pernit. The Town will have 18 months from
the effective date of this permit to install a continuous flow meter. Until then instantaneous
measurements can be taken with the duration of discharge to be noted in log books and a total daily
discharge reported on the DMR.
• The flow limit is removed.
• Turbidity monitoring is added with twice (2) per month monitoring.
• Total Iron, Manganese and Fluoride monitoring is quarterly.
• Total Copper, Phosphorous, Nitrogen monitoring is added with quarterly sampling.
• Chronic Whole Effluent Toxicity testing is added with quarterly sampling in January, April, July and
October.
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. [See Special

being physically located in an area where less than 10 percent of the households have broadband
access, then a temporary waiver from the NPDES electronic reporting requirements may be granted
