POTW Interview Notes:
POTW received a NOV for 1,4-dioxane 3/9/2023. Ms. Laughlin reports no problems related to industrial discharges and has had no
industries in SNC over the past two semi-annual periods. One dental practice is under construction and once complete, a compliance report
(dental amalgam rule) will be completed.
LTMP is being conducted properly.
Proposed changes in POTWpermit renewal (currently in DRAFT):
• IWC—Ammonia nitrogen limits have been revised.
• RPA show no potential for total chromium & total zinc, so they have been removed.
RPA shows potential to violate standards for total silver, bromodichloromethane and 1,4-Dioxane. These
parameters have been added.
Quarterly monitoring of total selenium has been added due to RPA
• SOC has been added to permit for total silver (WER study) or (CAP)
5-year phased SOC for 1, 4-Dioxane
• Instream monitoring for dioxane has been added.
• PFAS quarterly monitoring has been added starting 6 months when EPA has a final ww method
MMP has been added (Hg)
• Instream monitoring of nutrients added.
The 1, 4-dioxane SOC directs that all IUPs are modified or re -issued; new IUPs are issued; and/or other pretreatment
program mechanisms are completed to ensure compliance with the interim or final 1,4-dioxane limits. The permittee may
provide a pretreatment SOC for a given IUP that does not exceed the time to match the NPDES permit compliance schedule.
10#: Metlab #4 has not been in operation — not in production.
