Dear Mr. Brigham:

MAAONLINE.COM
On behalf of Ergon Asphalt and Emulsions Inc., Mid -Atlantic Associates, Inc. (Mid -Atlantic) is
pleased to submit the following response to the Notice of Deficiency NOD-2020-PC-0108 issued by
the North Carolina Department of Environmental Quality (NCDEQ) on March 12, 2020. This
correspondence was issued based on the results of a recent compliance evaluation inspection
conducted at the above -referenced facility on March 11, 2020. As requested, the following
response has been prepared to address the findings identified during the NCDEQ inspection.
A review of eDMRs for 2019 revealed several errors with reporting. Monitoring results
were not reported for the quarters starting in January 2019 and October 2019 despite
there being discharge events. There also appears to be no evidence of Acute WET
Toxicity being performed In January or April. Lab results were present on site, and no
discrepancies were found fnr data that had been reported for eDMRs However, we
recommend revising and resubmitting your eDMRs for 2019 to include missing
parameters. Since flow measurement is episodic, we also recommend leaving the No
Reporting Reason column blank In the future instead of putting no flow.
January/October 2019 Discharge SamDling: Please note that no discharges occurred from
the facility in January -February 2019. Quarterly effluent samples were collected during the
first discharge event of Q1 on March 13, 2019 and during the second discharge event of Q4
on December 3, 2019. The effluent samples were analyzed for pH, oil and grease and Total
Suspended Solids and have been reported to NCDEQ on the appropriate eDMR. The
results of the sampling events are also provided for reference as an attachment.

Quarterly Acute WET Toxicity Testing: The facility's current NPDES permit established a
new quarterly sampling protocol for Acute WET Toxicity parameters beginning in January
2019. Please note that prior to January 2019, Ergon was only required to perform Acute
WET Toxicity testing on an annual basis in accordance with the facility's previous NPDES
permit. As such, the samples collected during the first discharge event under the new permit
(March 2019) were inadvertently collected in accordance with the previous permit's sampling
protocol (i.e. pH, oil and grease and TSS). Upon further review of the updated permit
requirements, Acute WET Toxicity testing was then completed on a quarterly basis during
subsequent discharge sampling events conducted on April 23, 2019, July 9, 2019,
December 3, 2019 and February 4, 2020. The facility received passing results for each of
these events, and a copy of the April 2020 Acute WET Toxicity sampling results are
provided as an attachment, as requested. The next quarterly Acute WET Toxicity sampling
event is currently scheduled to be conducted at the facility on April 14, 2020.
Revision/Resubmittal of eDMRs: As requested, since flow measurement is episodic, the
2019 eDMRs have been revised and resubmitted with the "No Reporting Reason" column
left blank.
Gary Fischer (ORC) and Frederick Ammons (bORC) currently perform pH testing on
effluent during discharge events and transport samples to a certified lab. As stated in
Subchapter OSG of the North Carolina Administrative Code and Statutes, Grade 1
physicaUchemical systems should have weekly visitations by operators (15A NCAC
08G .0204 (2)(h)(i). The operator should come and view the treatment system at least
once a week, even during no discharge.
Mid -Atlantic previously reached out to NCDEQ regarding the weekly ORC visits outlined in
Subchapter 08G of the NC Administrative Code and Statutes, which state that "the ORC of
each Class I Facility (or the Backup ORC, when acting as surrogate for the ORC) must: visit
the facility as often is necessary to ensure proper operation of the treatment system; the
treatment facility must be visited at least weekly." During our initial discussions with NCDEQ,
the response we received was that we should be following the permit requirements, and the
facility complied as directed. However, following a weekly site visit conducted at the facility in
June 2017, Mid Atlantic reached back out to NCDEQ to request additional feedback as to
why weekly site visits would be required given the specific nature of the site (i.e. an on -site
retention pond strictly associated with stormwater runoff and controlled discharges only).
During our subsequent discussions, NCDEQ indicated that we would need to discuss this
with the permit writer, since he/she would have reviewed all of the facility's information
during the renewal process and would therefore be best prepared to answer our question.
As such, Mid -Atlantic reached out to the permit writer (Mr. Joe Corporon) on June 13, 2017
and received a verbal waiver for the weekly ORC site visit requirements. Mid -Atlantic then
issued a subsequent e-mail correspondence to NCDEQ documenting the results of this
conversation, and confirming that "Mid -Atlantic will be providing ORC oversight and
certification in accordance with the current permit requirements, with site visits conducted
prior to discharge events in lieu of weekly ORC visits." A copy of this correspondence is
provided as an attachment for reference.

At the time of inspection, the retention pond and outfall were found to be well
maintained. However, it is recommended that you remove woody vegetation and
weeds from the banks of the pond.
Following the March 2020 compliance inspection, the vegetation and weeds have been
removed from the banks of the pond, as recommended.
Mid -Atlantic appreciates this opportunity to respond to NCDEQ on behalf of Ergon Asphalt and
Emulsions, Inc. If you have any questions or need additional information, please feel free to contact
me at 919-250-9918 or Sean Randall with Ergon at 252-9914692.

CASE NARRATIVE ONE LAB NATIONWIDE
All sample aliquots were received at the correct temperature, in the proper containers, with the ❑
appropriate preservatives, and within method specified holding times, unless qualified or notated within
the report. Where applicable, all MDL (LOD) and RDL (LOQ) values reported for environmental samples
have been corrected for the dilution factor used In the analysis. All Method and Batch Quality Control
are within established criteria except where addressed in this case narrative, a non-conformance form
or properly qualified within the sample results. By my digital signature below, I affirm to the best of my 'Ss
knowledge, all problems/anomalies observed by the laboratory as having the potential to affect the
quality of the data have been identified by the laboratory, and no information or data have been
knowingly withheld that would affect the quality of the data.

Subject: ORC Certification for NCO0089087
Joe,
Thanks for your time this afternoon, just wanted to send a brief e-mail as a follow-up to the ORC requirements and
certification for the Ergon Asphalt & Emulsions, Inc. facility in Wilson NC. The facility is currently covered under NPDES
Wastewater Permit NCO0089087 (pending final determination of the permit application for coverage under a
stormwater permit) and will continue to operate in compliance with the current wastewater permit: until an outcome
has been determined and/or the facility is instructed otherwise by DEQ. During this time, Mid -Atlantic be providing ORC
oversight and certification in accordance with the current permit requirements, with site visits conducted prior to
discharge events in lieu of weekly visits. We will also be certifying the results of the April and May DMRs (which have
been previously entered into the eDMR system) and submitting hardcopy DMRs as discussed. Let us know if anything
changes or if you would like to discuss further, and thanks again for your assistance on this
