City Water Reclamation Facility Upgrade Dear Mr.Seat,
Attached is the requested preliminary wasteload analysis (WLA) for the Grantsville City Water Reclamation Facility Upgrade. WLAs are performed to determine point source effluent limitations
necessary to maintain designated beneficial uses by evaluating the projected effects of discharge concentrations on in-stream water quality. They are based on information available at
the time of development. Concentrations are then compared to numeric water quality standards todeterminetheir acceptability. Please note that this is a preliminary WLA, and the numeric
criteria in this WLA may be modified bynarrative criteria and other conditionsdetermined by the Division of Water Quality (DWQ) staff. The Level II Antidegradation Review (ADR), which
is a requirement for all new discharges, may also have an impact on limitations. Please note that local ordinances may also apply. The attached WLA is outside DWQ’s typical process of
developing a Utah Pollutant Discharge Elimination System (UPDES) Permit. DWQ staff spent 70 hours on this WLA, billed at $115/hourfor a total cost recovery sum of $7,798.75. The invoice
is attached – please pay within 60 days of the date on this letter. To proceed with the UPDES Permit process for this project, please submit a UPDES Permit Application and ADR Application.
If you have any questions regarding this matter, please contact Danielle Lenz at [phone] or by email at [e-mail]. Sincerely,Danielle LenzDanielle Lenz, ManagerUPDES Individual
