Re: Special Order By Consent Evaluation
NC DOT Maintenance Facility
Rosman, Transylvania County, North Carolina
H&H Job No. DOT-218
Dear Mr. Motzno:
Per your request, Hart & Hickman, PC (H&H) is providing this letter for the Special Order by
Consent (SOC) application that you are preparing for the NC DOT Rosman Maintenance
Facility. A ground water recovery system was installed in 1998 to remove chloride-impacted
ground water at this site. The chloride ground water impact originated from road salt storage.
The chloride-impacted ground water is removed using three recovery wells. The combined flow
from the three recovery wells is piped approximately 1 mile for discharge into the French Broad
River without treatment. Based on information provided by your office, the maximum flow rate
for the ground water recovery system is on the order of 5 gallons per minute (gpm). This flow is
very small compared to the river flow. This discharge is permitted under NPDES number
NC0085979.
As described in S&ME's Amended Corrective Action Plan (CAP) dated May 1998, discharge of
the recovered ground water without treatment is the only economically feasible approach for this
incident. S&ME made this statement because chloride removal methods are complex,
expensive, and operation and maintenance intensive.
S:\AAA-Master Projects\NC DOT\DOT-218 Rosman\SOC Eval.doc

Mr. Eric Motzno
July 15, 2005
Page 2
The NPDES permit requires quarterly whole effluent toxicity (acute toxicity) testing. Over the
topoint that thewater is failingthe toxicity
the chloride concentrations have increasedthe
testing. Therefore,NC DOT is planning to apply for the SOC.
The SOC application requires 1) an evaluation of the treatment units and operational procedures
with recommendations on maximizing facility treatment efficiency; 2) a certification that these
facilities can not be operated in a manner that would achieve compliance with final permit
limitations; and 3) an evaluation of the effluent limitations that the facility could be expected to
meet if operated at maximum efficiency.
Because treatment of the water was deemed economically infeasible and no treatment facilities
exist, the above SOC efficiency evaluations do not directly apply. However, one option that
could help to reduce aquatic toxicity is the addition of dilution water to the recovery well
effluent. Municipal water is available in the area. However, municipal water at the tap can
cause aquatic toxicity problems due to the presence of residual chlorine and trace metal
concentrations. To reduce residual chlorine in the municipal water, the water could be stored
(and aerated if needed) for a period of time to allow the residual chlorine to dissipate prior to
diluting the recovery well effluent. However, trace metals introduced from the municipal water
could still cause aquatic toxicity problems. To further evaluate the dilution option, H&H
recommends that samples of combined municipal water and effluent be collected and analyzed
for acute toxicity. Prior to preparing the sample, H&H recommends that the municipal water be
allowed to set in an open container for at least 8 hours.

RE: DRAFT NPDES Permit NC0085979
NC Department of Transportation
Transylvania County
Dear Mr. Guerra:
As we discussed on July 13, I have reviewed the draft NPDES permit, NC0085979, and
have one issue to solve. Our groundwater collection and discharge system(no treatment)
typically averages a pH of 5.3 to 6.0. This is a normal pH for groundwater in this area
including groundwater that is naturally discharging into the French Broad River. Since
the effluent has such a large dilution factor in the river,the pH quickly adjusts to that of
the river. Therefore, it is requested that the range of pH in the permit requirements be
changed to between 5.0 and 9.0.
Other items of interest that we discussed were the inactive county landfill adjacent to the
DOT facility. Our network of monitor wells on DOT property show that contamination
from the landfill is migrating towards the area where we are pumping groundwater.
Some of the compounds detected include vinyl chloride, benzene,tetrachloroethene,
trichloroethene, and xylenes. In past monitoring of the effluent of our pumping system,
no compounds listed on the EPA Methods 624 and 625 have been detected, but there has
always been that concern. County officials and their environmental consultant have
expressed their concern about the possibility of our pumping affecting the landfill's
plume.
Also on July 13, I discussed the situation with Kevin Bowden of the Aquatic Toxicity
Unit. When we started the pumping in 1998, the chloride level in the effluent averaged
about 3500 parts per million. This level seemed to be just below the toxic level for
fathead minnows and the quarterly sample events passed. As pumping continued over
Equipment and Inventory Control Unit,4809 Beryl Road,Raleigh,NC 27606
Telephone[phone] FAX[phone]

Mr. Bob Guerra

the years, the chloride concentration increased to about 4500 ppm. Mr. Bowden brought
up the idea of blending in fresh water to dilute/lower the concentration of chloride.
Chlorinated, city water is available on site and could be mixed with the effluent.
However, the residual chlorine may cause problems on the acute toxicity test. To obtain
more information about this, I talked to Jennifer Jones of Pace Analytical in Asheville.
We think the residual chlorine from the city water could be dissipated if we used a large
holding tank with an open top to temporarily store the water before mixing. If necessary,
an aerator could be added in the tank to speed dissipation of chlorine.
After these discussions, I talked to Matt Bramblett, PE,of Hart& Hickman. He is our
environmental consultant performing the evaluation of the system as required by Section
VI, part 5 of the SOC application. Mr. Bramblett thinks the costs of this modification
would be excessive. The modification would require 1000 to 1500 gallons of city water
every day. Considering that the town of Rosman has extended water lines throughout the
surrounding neighborhood, it is less likely that the continued spread of the chloride plume
would have a serious impact on nearby supply wells. Eventually, the Aquifer Protection
Branch would allow discontinuation of the remediation because of the costs would
exceed the benefit. At the Avery County DOT facility in Newland, a chloride plume
contaminated nearby supply wells. DOT paid for the extension of a city water main to
the area and DENR did not require any active remediation of groundwater since there
was no river to discharge into.
Please consider the information provided while working on the permit. If you have
questions, please call me at [phone].

SUMMARY
NCDOT operates a 0.0288 MGD Ground Water Remediation (GWR) facility which originally was
covered under General Permit # NCG510365. In 1992, salt (chloride) pollution plume was
detected in the groundwater<1 mile from the former salt storage facility operated by the
NCDOT. Monitoring of the plume was done from 1992-1998. The highest contamination in GW
occurred 10/19/95, 9950 mg/1 in MW-3. The facility was not planning any remediation;just
pump it to the French Broad River. After performing an EAA in 1996, ARO suggested that the
facility pump the contaminated groundwater and discharge it into the French Broad River. On
10-2-96 the facility was changed to an individual permit NC0085979 that discharges into the
French Broad River with monitoring requirements.
The facility pumps from three (3) recovery wells contaminated with chlorides (road salt). The
facility is required to do monthly monitoring for flow, Chloride and pH. Quarterly monitoring is
required for Chemicals - EPA Method 624/625 and Acute Toxicity (Fathead Minnow) Pass/Fail.
If the facility is required to construct additional treatment facilities (diffuser) due to violations of
water quality standards, no construction of facilities may begin prior to receiving an
Authorization to Construct.
The existing permit incorrectly identified this facility as being in Subbasin 04-03-02. I have
corrected this error to reflect the facility being in Subbasin 04-03-01. Originating in
Transylvania County, the headwaters of the French Broad and Little Rivers are in this
Subbasin. Most of this Subbasin is forested, and half of the land is protected as part of the
Pisgah National Forest. According to the Draft Basin wide Water Quality Management Plan for
the French Broad River there is only one 0.6-mile section at site SB-13 section that is currently
impaired due to a Fair Bio-classification, which may be attributable to Trout Farms on the West
Fork of the French Broad.
TOXICITY TESTING:
Current Requirement: Acute P/F @ 90% (also recommended with renewal)

COMPLIANCE SUMMARY: BASED ON THE PREVIOUS 2 YEARS
NCDOT Rosman Maintenance facility has had five "passes" between May 2003 and August
2004. The facility has had five failures during the same timeframe.
• 7- 03 -Acute Toxicity fail-No CP assessed
• 10- 03 -Acute Toxicity fail
• 11-03 -Acute Toxicity fail
• CP assessed of$1124.24 for 10-03 & 11-03 Acute Toxicity fail / paid 7-27-04.
• 4-04-Acute Toxicity fail
• 5-04-Acute Toxicity fail
• CP assessed of$1053.42 for 4-04& 5-04 Acute Toxicity fail / Paid 1-6-05
Facility has indicated communications with ARO to apply for an SOC. As to date nothing has
occurred towards this SOC application. Since the 5-04 Acute Toxicity fail, the facility had two
passes and has reported "No discharge" since 9-04.
Quarterly sampling (5-3-03 to present) utilizing EPA Methods 624/625 for chemical monitoring,
have not identified chemical pollutants above North Carolina Water Quality Standards.
Quarterly sampling for those parameters above detection level will continue in this permit.

Site Summary
In 1992, Mr. Paul Harris complained of salt in his residential supply well. His well is located
adjacent to and north of the DOT yard, approximately 350' from the old salt bin. The Division
of Water Quality collected a sample from the Harris well and laboratory results indicated a high
level of chloride that exceeded 2L Standards of 250 ppm. The DOT started monitoring his
supply well. Chloride concentrations in his well ranged from 500 to 525 ppm. Other nearby
supply wells were sampled at the Hardin, Huggins, Whitmire, and Crowe properties surrounding
the DOT yard. The Huggins property, located south of the DOT yard, had chloride levels that
continued to increase with each sample collection. The concentration was 147 ppm when last
sampled in April 1998. The house was vacated in the mid-1990's, so sampling of the supply
well was eventually discontinued. The County later bought the property and is not expected to
use the house. The Hardin well was clean, so Mr. Harris connected his house to it.
On November 5, 1992, four soil borings were advanced and soil samples were collected by
S&ME. The four soil borings were developed into monitor wells (MW 1 - 4). Groundwater
samples were collected and laboratory results indicated high levels of chloride in MW2 and
MW3. The source of contamination was determined to be the old salt bin. The salt bin was
unsecured and salt had leached into the underlying groundwater. The salt stockpile was later
moved to a secure salt bin on the DOT yard. Eleven additional monitor wells (MW5 - 11 and
MW 50 -53) were installed. S&ME provided a Comprehensive Site Assessment in 1996 and a
Corrective Action Plan in 1998. MW-3, in the source area was found to contain as much as 26,
000 ppm of chloride. DOT personnel collected groundwater samples quarterly for the first 10
years of the project and semi-annually since then.
The Corrective Action Plan proposed pumping contaminated groundwater from the site to the
French Broad River without any treatment. A NPDES permit was received from DENR in 1997.

This permit allowed the discharge for a period of 3 years. The permit was re-issued in 2000 for a
period of 5 years and is currently in process of being re-issued. Aquaterra installed a pump and
discharge system at this site in early 1998. The system consists of three recovery wells, electric-
submersible pumps, flow meters, and a control panel. The discharge line is a 4-inch diameter,
PVC line installed along the road right-of-way between the maintenance facility and the French
Broad River. The system operated from June 4, 1998 until May 2004 and pumped almost 7.5
million gallons of water as of June 1, 2004. The effluent concentration averaged 3,500 ppm.
The daily flow rate averaged 0.0050 million gallons. Table 1 is a summary of the effluent sample
results. Approximately 220,000 lbs. of salt was discharged into the river between 1998 and
2004. The system was turned off in late May 2004 because of failing acute toxicity tests.
Beginning in the summer of 2003, the chloride levels increased to about 4500 ppm and we
started failing the acute toxicity tests. Eventually, the Division of Water Quality issued 2 civil
penalty assessments for the failed tests. The DOT conducted several tests using chronic toxicity
tests. These tests passed by a small margin. Also, a DOT contractor performed a system
enhancement evaluation. This report prepared by Hart & Hickman concludes that the best
method to increase the chance of obtaining passing toxicity tests is to dilute the effluent with city
tap water. It was also mentioned that residual chlorine and trace metals found in city tap water
could pose problems.

RE: NPDES Permit NC0085979
NC Department of Transportation
Transylvania County
Dear Mr. Weaver:
Enclosed is a NPDES permit application to renew permit#NC0085979. This permit
expires September 30, 2005 and is for the discharge of groundwater contaminated with
chlorides. Groundwater is being pumped from 3 recovery wells at the DOT Maintenance
facility and piped down to the French Broad River without treatment. There have been
no changes in the collection system since the last renewal of the permit. Included in this
renewal packaged are one original and 2 additional copies each of the cover letter,
application(short form C-GW), a summary of the most recent analytical results and a
USGS topographical map showing the locations of the site and discharge point in the
river.
,,Wkiftekr of RoSnitritikextendeittlywner limos to the> surrounding-Ow
I 'facilRrf was hoping the Asheville Regional Office woald suspend-the
seguirement of remediating the site after the nearby supply wells are replaced:.For now,
eheyate requiring we continue the pumping. There is no sludge accumulation associated
with the system. Also, there have been no complaints or problems associated with the
discharge into the river. audvimainued pumping, I expect the effluent chloride
concentration to increase resulting in failing tests for acute toxicity. We investigated
using chronic toxicity testing last summer, but those tests barely passed. 4 am preparing
an SOC to allow for an exception to toxicity testing requirements. We will continue
working with the Regional Office to develop a solution to the testing problem.
