Permit # WQOOO27O8
Department of Environment & Natural Resources
Division of Water Resources - Information Processing Unit
1617 Service Center
Raleigh, NC 27699
As a part of the permit renewal application, the City of Raleigh submitted monitoring data showing that the
naturally occurring background concentrations exceed the groundwater quality standards for arsenic, iron,
and manganese. Per 15A NCAC 02L .0202(b)(3), the Permittee had applied to the Director to establish
background concentrations and site -specific water quality standards for these parameters. Final
determination of background concentration for arsenic, iron, and manganese were pending upon issuance
of the final permit. The monitoring data submitted by the City was collected consistent with the Division's
requirements as they applied in 2010 and the monitoring data was gathered and analyzed by a consulting
firm the Division has recognized as competent to make such determinations at the Neuse River Wastewater
Treatment Plant's biosolids application fields. It was requested by the City that until additional site specific
data is approved by the Division, the Division would apply the City submitted data as the best available scientific
evidence of the naturally occurring groundwater conditions for arsenic, iron and manganese at the Wrenn Road
Spray Irrigation Facility.
This report submission shows manganese data above the permitted levels and PH data below the permitted
range for the groundwater standards listed in attachment "C" of the permit. The historical manganese and
PH data provided in a 1990 consultant report as part of a land treatment site evaluation and the 2010
consultant report submitted during the most recent permit renewal process shows background data
consistent with current manganese and PH levels and should be considered as naturally occurring
background water quality.
In attachment C, footnote 8 of the final permit, it states that the Division shall use enforcement discretion for
any apparentground waterstandardviolation forarsenic, iron ormanganese until background concentrations and
site -specific groundwater quality standards can be determined.
