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 apparent ground water standard violation for arsenic,iron or manganese until background concentrations and
site-specific groundwater quality standards can be determined.

be submitted after the established due date?
2 Was any required information missing on the CW-59 report forms? YES NO
IF the answer to question 1 or 2 is"YES", list in the space provided below the well identification number(s)and
explain the problems encountered in obtaining the required information.
3 Arc any of the monitor wells in need of repair or maintenance(damaged casing,unlocked or missing cap,missing YES NO
identification plate, area overgrown,etc.)?If the answer is "Yes", contact the Regional Office for guidance.
4 Are any monitored constituents equal to or above the established standards? 1'ES NO
If the answer to question 4 is"NO",skip to section 8.
If the answer to question 4 Is"YES"list the affected wells individually with constituent(s)and concentration(s)
exceeding standards in the space provided below:
MW9 pH6.29
5 For the constituents identified in question 4 above,have standards been exceeded previously for the YES NO
same constituent(s)in the same well(s)in the last two years?
If the answer to question 5 is"NO", skip to section 8.
If the answer to question 5 is "YES';list in the space provided below, each well with constituent(s)exceeding
standards, concentration(s)reported, and sample collection date for each occurrence(for the last two years).
The pHs for MW 3,MWS,and MW9 are in the standard range for the City of Raleigh
Iron and Manganese are new groundwater characteristic listed in the new permit
See the attached document regarding the constituents
6 Are the monitoring wells listed in section 5 located at or beyond the review boundary? YES NO
If the answer is"YES",a groundwater quality problem may be occurring. CONTACT THE REGIONAL
OFFICE IMMEDIATELY FOR GUIDANCE.If the answer is"NO", monitoring wells may be improperly
located;contact the Regional Office.
7 is the permittee implementing previously approved actions required by the Division involving this YES NO
groundwater quality problem?
If the answer to question 7 is"YES",describe those actions in the space provided below.
If the answer to question 7 is "NO",contact the Regional Office within 90 days;an evaluation may be
required to determine the impact the waste disposal system is having at the review and compliance
boundaries surrounding this facility. Failure to do so may subject the permittee to a Notice of Violation,
fines,and/or penalties.
8 The person completing this portion(GW-59A)of the monitoring report should sign below and submit this
form with GW-59 forms for required wells to the address provided at the top of the current GW-59 form.
