RE: 2023 4th Quarter DMR—NCG060445
Morton Salt Inc. —Siloam, North Carolina
To Whom it May Concern:
Triton Environmental, Inc. (Triton) is providing the enclosed Discharge Monitoring
Report(DMR) for the 2023 4th quarter monitoring period on behalf of the Morton Salt, Inc.
(Morton) for its site located in Siloam, North Carolina (COC No. NCG060445).
Morton understands that DMRs are to be submitted using NCDEQ eDMR for permittees
covered under the general permit. However, Morton is awaiting eDMR account registration
approval. As such, submission of the DMR is being completed via hardcopy at this time. An
electronic copy was also submitted using the "NCDEQ Stormwater NPDES Permit Discharge
Monitoring Report Upload" webpage.
Based on the results of quarterly monitoring, Morton has completed or will be completing
the additional required actions to address the Chemical Oxygen Demand (COD) concentrations
above the benchmark level. These actions include stormwater management inspection,
identifying and evaluating possible causes of the benchmark exceedance, selecting and
implementing specific courses of action in accordance with the Tier I response schedule
identified in Part E.5. of the permit.
Thank you for your attention to this matter. If you have any questions or comments,
please contact me at 203.458.7200.
Sincerely,
