Subject: NPDES Permit-DRAFT Review
Permit NC0082996
Hollybrook WTP, Class PC-1
Kildare Farm Road, Cary
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:
1. DWR has discontinued monitoring for Total Iron [no standard/no longer
a parameter of concern (POC)].
2. Per potable water treatment plant(WTP) strategy(2012), continued quarterly
monitoring for Total Manganese(no limit) as required of greensand filter
treatment technology.
3. Total Nitrogen/Total Phosphorus (TN/TP)remain in the permit,
monitoring semi-annually per current Neuse River Basin Nutrient
Management Guidelines.
4. Because TN/TP monitoring is required, this facility is not eligible for WTP General
Permit NCG590000.
5. Updated site map and the Supplement to Permit Cover Sheet narrative.
