DMON |
Acrolein and acrylonitrile, Volatile Organic Compounds (VOCs) required to be analyzed from facility effluent sampled at EFF-001 once per year pursuant to the Remaining Priority Pollutants defined in 40 CFR Part 131, were not analyzed in 2025. These pollutants are analyzed by EPA method 624; however, EPA method 624 analysis requires samples to be collected in Volatile Organic Analysis (VOA) vials preserved with hydrochloric acid and acrolein and acrylonitrile require separate, unpreserved VOA vials. |
This error was identified during preparation of this report and was corrected prior to the first discharge event of 2026. The facility has since analyzed acrolein and acrylonitrile (both resulted as Non-Detect) which will be included in Quarter 1 2026 SMR and 2026 Annual Report. |

DMON |
Total Recoverable Mercury is required to be analyzed once per discharge event pursuant to NPDES Permit Table E-2, but it was not analyzed from the sample collected on April 3, 2024. |
Total Recoverable Mercury is a requested analysis on all sample event Chains of Custody during this reporting year, as reflected in the copies of these forms within each laboratory report. While Total Recoverable Mercury was not analyzed as requested from the sample collected on April 3, 2024, it was analyzed as requested from samples collected on April 10, 2024 and April 24, 2024. By the time Total Recoverable Mercury was identified missing, the laboratory no longer had any reserve sample volume available to perform the analysis. In the future, Zenith representatives will perform additional, timely QA/QC to ensure all requested analyses are performed by the laboratory. |
