See this announcement of a Sept 7 public hearing  in Raleigh.  This is a 
City of Raleigh WWTP matter, BUT a relaxing of DENR rules could have 
repercussions elsewhere in the state.

This is an announcement of a Sept 7 public hearing in Raleigh about City of 
Raleigh's request to NOT do a full-scale cleanup (as required by DENR rules) 
of nitrate contamination into groundwater from land application of WWTP 
residual on 1,400 acres around its WWTP.  This could set a precedent for all 
WWTPs that have similar problems with groundwater contamination from its 
sludge.  I do not know what is meant by Raleigh's request for a "natural 
attenuation corrective action plan," but that will be discussed in the 
hearing.  This would be good for the Sludge folks to hear about, too.

speak.  All comments received within 30 days following the date of the 
public hearing will be made part of the variance application file and will 
be considered prior to taking final action on the application.

After considering all comments submitted, the hearing officers, on behalf of 
the DENR-DWQ will make a recommendation to the EMC on the variance request. 
The EMC will take final action on the variance application.

BACKGROUND
The City of Raleigh (Raleigh) has applied for a variance to State 
Groundwater Standards, 15A NCAC 2L .0107(k)(3)(A).  Raleigh has requested 
they be allowed to implement a natural attenuation corrective action plan 
(CAP) per  15A NCAC  2L .0106 for nitrates that have migrated offsite from 
the NRWWTP.  State groundwater rules do not allow natural attenuation as a 
cleanup method used by permitted facilities, therefore a variance is being 
sought.  Land application operations at this facility are regulated by 
Permit # WQ0001730.  Raleigh is responsible for cleanup of nitrate that has 
migrated outside the permitted compliance boundary.  DENR-DWQ recommends 
that natural attenuation with groundwater containment is appropriate based 
on information contained in the variance request and technical review by DWQ 
staff.

The area for which the variance is requested is land at the NRWWTP in the 
southeast portion of Wake County consisting of approximately 1,466 acres and 
37 parcels of land adjacent to the property along Old Baucom Road, Mial 
Plantation Road, Shotwell Road, and Battlebridge Road.  The City of Raleigh 
Public Utility Department (CORPUD), One Exchange Plaza, Suite 620, Raleigh, 
NC, used its land to apply wastewater treatment plant residuals. CORPUD has 
currently suspended the application of residuals. Properties surrounding 
this site consist of residential properties, farmland, commercial, and 
state-owned forestland.

Nearby private wells that were impacted by nitrate associated with the 
over-application of residuals have either been abandoned per the state's 
well construction rules in 15A NCAC 2C .0100 or are no longer in use as a 
source of drinking water supply.  Downgradient private well owners with 
abandoned wells are now served by water from Raleigh.

If granted, the variance will require implementation of corrective action 
under 15A NCAC 2L .0106(k) and will lead to changes in the permit including 
downgradient containment and long term monitoring of nitrate in lieu of a 
full scale cleanup. The proposed variance request will not change the 
standard for nitrate of 10 milligrams per liter that the facility must meet 
under its permit obligations. No other substance monitored at this facility 
is under consideration. As proposed, the variance implements on-site 
mitigation (installation of three subsurface flow wetlands) to address 
nitrate-contaminated groundwater that is impacting several streams that 
discharge into the Neuse River.  Active remediation has been initiated to 
treat contaminated groundwater near the intersection of Mial Plantation Road 
and Baucom Roads, areas where groundwater may be restored as a future source 
of drinking water. The alternative remediation of streams through the use of 
subsurface flow wetlands a!
nd the active groundwater remediation system will be included in the DWQ 
Permit # WQ0001730.
