Pretreatment Annual Report
Narrative
The Town of Hamilton owns and operates an 0.08 MGD wastewater treatment facility with one
(1) industrial discharger, Penco Products, Inc. Penco Products is a categorical user (433.17) that
manufactures metal goods, primarily lockers.
Penco has been issued an Industrial User Permit that requires self monitoring on a quarterly basis.
In addition, the town also samples the facility on a quarterly basis. Over the years the industry has
had very few problems complying with their permit limits.
In the past year the industry has continued to encounter some problems as a result of a turnover in
personnel and new employee's having difficulty in locating files kept by previous staff. The
industry's discharge has generally been compliant. There has been a potential for excessive Zinc
concentrations but the violations have been few and additional testing with improved results tends
to help address these. Notices of Violation were issued for BOD, Zinc, excessive flow in October,
and on failure in reporting that actually occurred during the final quarter of 2017. Sampling and
testing for the parameters outlined in the permit have been competed as required.
Penco Products struggled with Zinc concentrations in 2017 and has worked to get better control
of their standard procedures and to develop a standard operating procedure to ensure better
performance regarding compliance with their Industrial User Permit. The industry's compliance
with the terms of their Industrial User Permit has improved.

Dear Pretreatment Professionals:
As we draw to the close of another great pretreatment year, I wanted to provide you an update on some issues,
inform you on this year's upcoming workshops and distribute the Pretreatment Program Info Database sheets.
1) Annual Pretreatment Conference: Due first to Hurricane Florence and then an early winter snow storm, the
annual conference scheduled for Wrightsville Beach was canceled. PT 101 has been rescheduled for January
17, 2019 at the NC -PC Industry Day in Greensboro. Please see the NC -PC web site for further information.
2) Dental Amalgam Rule: A Draft enforcement policy was sent to the NC -PC Mercury Workgroup on November
30. PERCS would like to have the initial comments by January 31, 2019.
With the promulgation of the dental amalgam rules there have been several inquiries regarding removing the
Mercury Minimization Plan (MMP) requirement from NPDES permits. Currently requests to remove the MMP
can be made if a POTW can demonstrate effluent mercury concentrations consistently below 1 ng/I. Future
request could be considered, even if the effluent concentrations are not consistently below 1 ng/I, if a reduction
in influent mercury concentrations can be shown and the POTW can verify that most (>90%) dental users
within their jurisdiction have installed amalgam separators.
3) Rules Review: The EMC approved the rules at the March 8, 2018 meeting. Two public hearings were held in
May. No comments regarding the pretreatment rules were received. The Hearing Officer's report is currently
in draft.
4) NPDES Pollutant Scans: It has been noted that detection levels used for the effluent pollutant scans are
sometime different than those used in the pretreatment long/short term monitoring plans. All of this data is used
by the NPDES permit writer when performing the reasonable potential analysis. Having differing detection
levels may cause the data to show reasonable potential to violate the standard and result in a limit in your
NPDES permit. Please contact your contract lab and make sure the same sufficiently sensitive detection levels
are used for all effluent analysis. The current required detection levels for silver = 1 ug/I; cadmium = 0.5 ug/I
and; selenium = 1 ug/l.
5) Division Review of IUPs: The Division continues implementation of the streamlined permit review process.
After attending the IUP workshop and a thorough Division review of three program IUPs, a permit writer may
be approved to participate in this process. Permits submitted under this process are not subject to a full Division
review. Benefits to the POTW include less paperwork to submit and immediate approval of your permits.
6) Staff Assignments: Our goals for project review are 30 days for IUPs and SIU drops and 90 days for ERP,
HWA, IWS, LTMP and SUO. Last year we met our goal 99% of the time.
Please note our phone numbers have changed. � ��—��^^��

are posted on the Training page: http://deg nc gov/about/divisions/water-resources/water-resources-
training/training/pretreatment-program-training. Contact PERCS to register and please register early, as
space is limited at each site.
Pretreatment Annual Report (PAR) — January 241h (Raleigh) and January 29th (Salisbury)
Headworks Analysis (HWA) — January 30th (Salisbury) and April 11th (Raleigh). [HWA workshops may be re-

8) Pretreatment Program Info Database Sheets: Please review your attached program info sheet(s) and historical
SNC sheet(s), if applicable, and make necessary updates to any of the information presented. Send the
corrected sheets back with your PAR, due March 1, 2019. If all the information was correct, please indicate
that in your PAR. Especially note the due dates as this may be the only reminder you get. Please note:
a. All pretreatment programs (full and modified) must submit a PPS form with their PAR per an EPA
requirement of the State.
b. Historical SNC sheets only list currently Active SIUs that had SNCs from 2011-2017.
c. PAR forms are available for download on our website: http7//deci.nc.gov/about/divisions/water-
resources/water resources-permit-guidance/pretreatment-guide/annual-report-guidance
9) Email Addresses: PERCS often uses email to send out mass mailings. To make this an effective and cost
saving tool, we ask that you keep PERCS updated on your current email address as well as which staff member
is the "primary' contact for your POTW - see "prim" field next to staff names on Program Info sheet, and email
field below names. For programs with more staff than the printed sheet can show, a separate contacts page
has been included. Please make any staff changes on that sheet and return to PERCS with the PAR.
As always, please contact your pretreatment staff member (as listed above) or me at 919-707-3624 email:
Deborah.Gore0mcdenrAOyl with any questions or comments.
Sincerely,
Deborah Gore, PERCS Unit Supervisor
