Subject: Stormwater Discharge Outfall Monitoring Report
Certificate of Coverage NCG12006
Dear Mr. Bennett:
Attached is the Stormwater Discharge Outfall Monitoring semi-annual report for Energizer
Battery's industrial landfill as required by General Permit No. NCG 120000 for the month of
September 2020.
Pyramid Environmental Inc. was retained to perform the required stormwater sampling. The
location of our site is shown on the maps in Attachment A. A qualitative monitoring report for
Outfall A taken at the time of the sampling event is presented in Attachment B. Laboratory
results are presented in Table 1, Attachment C,which lists all results since the installation of
Weir A. Table 2, in Attachment C, shows the historical laboratory results for Outfall #1 and
#2, which preceded Weir A. The completed Semi-Annual Stormwater Discharge Monitoring
Report is included as Attachment D.
The analysis of the September 17th sampling event from Weir A recorded the COD at 55 mg/L
and the TSS at 14.3 mg/L,therefore,the September 17th sampling event concluded all parameters
were below the benchmark concentrations per general permit NCG1200000. Additionally,the
sampling event reported a Fecal Coliform value of>12,000 col/100mL,which is above the
benchmark. It should be noted however,the landfill was relieved of the compliance requirement
for this benchmark because the landfill contains a single waste stream, alkaline batteries,which
cannot contribute to this benchmark. If you have any questions,please call Julia Bowman,the
Environmental Coordinator for Energizer's Asheboro facilities, at 336/672-4546.
Sincerely,
Steve Hall

RE: Semi-Annual Stormwater Sampling and Analytical Results—2nd Half 2020
Energizer Battery Landfill at Randolph County Landfill,Asheboro,NC
Pyramid Project#2020-191
Energizer PO#7000046465
Dear Ms. Bowman:
As requested by Energizer, Pyramid Environmental & Engineering, P.C. has completed the
stormwater sampling and analysis for the referenced site. The site is shown on the site location
map included in Attachment A. The Energizer Landfill is located within the Randolph County
solid waste landfill and includes one outfall (Weir A). An aerial photograph showing the location
of the outfall is included in Attachment A.
Corrective Action Plan and Re-Grading of Energizer Landfill
In November 2011, Energizer completed corrective actions at the landfill to direct all stormwater
run-off from the active and inactive landfill cells to a retention pond on the east side of the
property. Areas of the property were graded, and soil berms were constructed to direct all
stormwater to the retention pond. The purpose of the corrective actions was to improve the
quality of the stormwater run-off that leaves the property. As part of the corrective actions, the
two previously used outfalls were eliminated, and a new outfall was created (Weir A). The v-
notch weir that was previously located at outfall #02 was moved and installed on the down
gradient side of the retention pond in the riprap energy dissipation zone.
Sample Collection and Laboratory Analysis
On September 17, 2020, the stormwater samples were successfully collected at the site by Tim
Leatherman of Pyramid during a representative rain event. The qualitative monitoring report was
completed for Weir A by Pyramid and is included in Attachment B. The qualitative monitoring
report describes the visual appearance of the stormwater run-off at the time of the sampling
event.No unusual conditions were observed by Pyramid.
The stormwater samples were placed on ice and transported to Research and Analytical
Laboratories, Inc. in Kernersville,North Carolina. The samples were analyzed for fecal coliform,
total suspended solids (TSS),chemical oxygen demand(COD) and pH. In 2019,the NC Division
of Water Quality added pH to the list of required parameters for General Permit NCG120000.

Email:Infona,pyram idenv ironmental.com
www.pyramidenvironmental.com
The laboratory results of the stormwater samples are presented in Table 1, which is included in
Attachment C. As shown in Table 1,the detected concentrations of TSS and COD at Weir A do
not exceed the benchmark values specified in General Permit NCG120000 and laboratory pH
reading was within the specified range of 6.0—9.0.
The detected concentration of fecal coliform at Weir A (>12,000 colonies/100 milliliter) exceeds
the benchmark value of 1,000 colonies/100 milliliter (ml) specified in the general permit.
Energizer has received an exemption from the DEQ for monthly sampling of fecal coliform.
Regardless of the results, the fecal coliform analysis is only required as part of the normal semi-
annual sampling events.
For comparison purposes, a table of historical analytical results for the former outfalls (Table 2)
is also presented in Attachment.C. A copy of the laboratory report for the September 17, 2020
sampling event is also included in Attachment C.
Based on the results of the September 2020 semi-annual stormwater sampling event, monthly
sampling and analysis is not required at Weir A at this time.
Pyramid also completed the stormwater discharge monitoring report for Weir A as specified in
General Permit NCG120000. The completed monitoring report is included as Attachment D. A
representative of Energizer is required to sign page two of the monitoring report and send the
original and one copy to the address shown on page two.
The next semi-annual sampling event will be performed between January 1 and June 30, 2021.
The samples will be analyzed for the compounds as specified in the general permit. Please
review this information and call me at 336-335-3174 if you have any questions.

(See information below.)
Yes ❑ No
Please verify whether Qualitative Monitoring must be performed during a "representative storm
event"or"measureable storm event"(requirements vary,depending on the permit).
j Qualitative monitoring requirements vary. Most permits require qualitative monitoring to be
performed during a"representative storm event"or during a"measureable storm event." However,
some permits do not have this requirement. Please refer to these definitions,if applicable.
A"representative storm event"is a storm event that measures greater than 0.1 inches of rainfall
and that is preceded by at least 72 hours (3 days) in which no storm event measuring greater than
0.1 inches has occurred. A single storm event may contain up to 10 consecutive hours of no
precipitation.
A"measurable storm event"is a storm event that results in an actual discharge from the
permitted site outfall. The previous measurable storm event must have been at least 72 hours
prior. The 72-hour storm interval does not apply if the permittee is able to document that a shorter
interval is representative for local storm events during the sampling period,and the permittee
obtains approval from the local DWQ Regional Office.

1 Monthly sampling(instead of semi-annual)must begin with the second consecutive benchmark exceedance for the same parameter at the same outfall.
2 For sampling periods with no discharge at any single outfall,you must still submit this discharge monitoring report with a checkmark here.
'The total precipitation must be recorded using data from an on-site rain gauge. Unattended sites may be eligible for a waiver of the rain gauge requirement.
See General Permit text,Table 1,identifying the especially sensitive receiving water classifications where the more protective benchmark applies.
Note:Results must be reported in numerical format. For example,do not report Below Detection Limit,BDL,<PQL,Non-detect,ND,or other similar non-
numerical format. When results are below the applicable limits,they must be reported in the format,"<XX mg/L",where XX is the numerical value of the
detection limit,reporting limit,etc.in mg/L. Conversely,where fecal coliform results exceed the dilution upper limit,report the result as">XX".
Note: If you report a sample value in excess of the benchmark,you must implement Tier 1,Tier 2,or Tier 3 responses. See General Permit text.
