Subject: NPDES Permit NC0087998 -DRAFT Review
Rand Meadows Phase II Water Treatment Plant(WTP)
NCRS 1010 and Rand Road, Raleigh
Wake County
Dear Mr. Becker:
Based on your request to renew the subject permit, the Division of Water Resources (DWR or
the Division)hereby transmits a renewal draft for your review and comment. Please review it
carefully to ensure your understanding of the limits and monitoring conditions, and to correct
errors, if any.
Summary of Changes to the Previous Permit-- The following will be incorporated into the
permit renewal:
1. Discontinued monitoring for Total Iron [no longer a parameter of concern(POC)].
2. Total Nitrogen/Total Phosphorus (TN/TP)remain in the permit,monitoring semi-
annually per current Neuse River Basin Nutrient Management Guidelines.
3. Because TN/TP monitoring is required, this facility is not eligible for WTP General
Permit NCG590000.
4. Added Total Hardness monitoring for future evaluation of metals in dissolved fraction
.5. Updated site map and the Supplement to Permit Cover Sheet narrative.
Concurrent with this notification, the Division will solicit public comment on this draft by
publishing a notice in newspapers having circulation in the general Wake County area, as
required by the NPDES Program. Please provide your written comments, if any, to DENR/
DWR/NPDES Program no later September 17, 2018 (approximately 30 days after receiving
this document). Your written comments are welcome,but are not mandatory.
