DESCRIPTION OF PERMIT MODIFICATION
On January 1, 2023,the City of Orem’sUtah Pollutant Discharge Elimination System (UPDES) Permit No. UT0020915 was modified. The UPDES Permit granted the City of Orem a compliance schedule
to meet the Technology-Based Phosphorus Effluent Limit (TBPEL) Rule, Utah Administrative Code (UAC) R317-1-3.3. The Permittee received an initial variance to the TBPEL Rule before it
went into effect in 2020, allowing until January 1, 2023. Due to construction delays, a compliance schedule was incorporated. The permittee requested an extension of the compliance schedule
on November 12, 2024. As part of the variance, the Facility was required to meet an interim annual average effluent total phosphorus(TP) of 2.5 mg/L between January 1, 2020, and December
31, 2024.
The Facility upgrades were set to be complete in fourth quarter 2024. However, due to construction delays and other unforeseen circumstances, the final completion date will now be sometime
in 2025. As a result, the permittee has requested an extension of thecompliance schedule for the total TP limit required by the TBPEL Rule. The Division of Water Quality has granted
this request, as the construction delays were out of the Permittee’s control. As a result, the TBPEL Rule compliance date is now being moved to January 1, 2026, with an interim annual
average TP limit of 2.5 mg/L. The below permit limits and Compliance Schedule are also reflected in Part I.C.2. and Part I.C.3.of UPDES Permit No. UT0020915.
All other parameters in the permit will remain unchanged.
