Dear Mr. Wolfe:
Statute 143 -215.1 and the Memorandum of Agreement between North Carolina and the U.S.
Environmental Protection Agency dated October 15, 2007, or as subsequently amended.
This permit was originally issued in October 2013 for a limited timefrarne to accommodate
dewatering activities associated with storm drainage improvements. This permit modification
includes the following changes to the existing permit:
1 . Change the permit expiration date from June 30, 2015 to June 30, 2016 to accommodate
the updated stormwater construction schedule. The total permit duration is less than 3
years,
2. Addition of Outfalls 004 and 005, which may be used depending on site constraints for
the groundwater remediation system (s). These additional outfalls would discharge to the
same receiving waterbody (UT Little Sugar Creek).
3. Delete flow limit in Effluent Sheet A(l), and replace with Monitor -only condition,
If this temporary construction activity is completed prior to June 30, 2016, please notify the
Division and request permit rescission.

activities on the flow device.
Daily Dischqrge
The discharge of a pollutant measured during a calendar day or any 24-hour period that reasonably represents the
calendar day for purposes of sampling. For pollutants measured in units of mass, the "daily discharge" is calculated as
the total mass of the pollutant discharged over the day. For pollutants expressed in other units of measurement, the
"daily discharge" is calculated as the average measurement of the pollutant over the day. (40 CFR 122,2; see also
"Composite Sample," above.)

Tests have shown contamination of groundwater with chlorinated solvents higher than surface water
standards, likely from Dry Cleaner operations in the past. These solvents are primarily
Tetrachloroethylene (PCE, or PERC) and various decomposition byproducts such as Acetone,
chloroform, cis- 1,2-Dichloroethylene, Naphthalene, and Trichloroethylene, They plan to conduct
remediation of, the groundwater from the excavation and tunneling operations by use of adsorption in
activated carbon columns. The duration of the project is approximately one year, and includes three
treated water outfalls to the City's storrawater drain system with discharge to an Unnamed Tributary
to Little Sugar Creek, a Class C waterbody. Little Sugar Creek is classified at the discharge site as
Impaired for Copper in the EPA approved 2012 303(d) list. It was also listed as impaired for Mercury
because of fish consumption advisories, but there is an approved Statewide Mercury TMDL, so the
mercury impairment has been removed.

operation for approximately 3 months each,
Whole Effluent Toxicity (WET) Test
WET testing is not required in this permit due to the short term project duration,
Reasonable Potential Analysis (RPA)
RPA analysis (please see attached) was based on the assumption that the system will operate with
90% removal efficiency, using the maximum reported contaminant concentration for each
component. Maximum predicted effluent concentrations were detertnined based on a coefficient of
variation of 0.6 and multiplier of 13.2 (as outlined in NC's RPA procedure based on EPA's Technical
Support Document, n = 1).
Limits and monitoring
As a result of the RPA, those chemicals showing Reasonable Potential (RP) to exceed the Water
Quality Standard were given limits equal to the WQ standard as a chronic, or Monthly Average limit
based on zero flow of the receiving UT. For these compounds, the Standards Group was consulted to
determine any published acute standards, which were given as acute, or Daily Maximum limits.
Compounds with RP but no acute WQ standards were given Monthly Average limits only. If the
predicted concentration was less than the WQ standard, but greater than SO% of the standard,
Monthly Monitoring was assigned with no limit, If the predicted concentration was less than the WQ
standard, but the chemical is a human carcinogen, Monthly Monitoring was assigned with no limit. If
the predicted concentration was less than 50% of the WQ standard and the chemical is not a human
carcinogen, or if there is no WQ standard for that chemical, no monitoring was required. Chloroform
did not show RP, but monitoring is required as it is listed as a human carcinogen. of Effluent
Toxicity Testing was not required due to the short term nature of this project, Each outfall will only
be in service for a few months before work moves to a different location.
