DESCRIPTION OF FACILITY & BACKGROUND
GPM Enviro Project Manager, LLC (GPM) manages the former Anderson Geneva Development, Inc. UPDES Permit and property, whichwas previously a defunctintegrated steel mill located in the
town of Vineyard, Utah, just east of Utah Lake in Utah Countywith the above-mentionedUPDES permit and facility address (facility). As of June 2010, the steel making machinery and mill
had been dismantled and removed off site, and all of the buildings and other structures at the facility have since been demolished. GPM’s operationsduring the ongoing redevelopment of
the facility property have fallen under two Standard Industrial Classification (SIC) Codes: 4953 – Refuse Systems and; 5093 – Scrap and Waste Materials.
Regarding wastewater discharges at the facility, the only operation currently remaining onsite is the ongoing Resource Conservation and Recovery Act (RCRA) Ground Water Treatment Unit
for discharges via Outfall 005-B. Due to historical ground water impacts on site, monitoring wells were previously installed for long term monitoring and treatment of the impacted ground
water. A Granular Activated Carbon (GAC) Treatment Unit has been utilized for many years to treat the ground water prior to any discharges.The current GAC Treatment Unit was installed
in late 2019along with the relocated outfall(005-B) as part of a previous permit modification process to replace the original GAC unit and outfall location. The treated water from the
newerGAC unit is batch discharged intermittently through Outfall 005-B to an internal drainage ditch on the property, which then flows into the site storm water collection system and
eventually may ultimately flowinto Utah Lake.
With the limited wastewater discharge operations that remain onsite, GPM requested a permit reclassification change from Major to Minor status. EPA approved the request on October 25,
2024 and provided the Division of Water Quality with the formal approval on November 22, 2024. With this approval and permit reclassification change, GPM has subsequently requested the
removal of the Biomonitoring Whole Effluent Toxicity (WET) testing requirements from the UPDES permit as they have not failed a WET test in many decades and are thereby now eligible
for WET testing reductions or elimination as per DWQ WET Policy entitled, Utah Pollutant Discharge Elimination System Permit and Enforcement Guidance Document for Whole Effluent Toxicity
Control (biomonitoring), February 2018. DWQ has reviewed all available information and determined that the removal of the WET testing requirements from the UPDES permit is warranted
and appropriate at this time.
SUMMARY OF PERMIT MODIFICATION CHANGE
As mentioned above, the Biomonitoring WET testing requirements have now been removed from the permit. However, the permit will still contain a toxicity limitation re-opener provision
that allows for modification of the permit in the future should additional information indicate the presence of toxicity in the discharge.
This change is the only change being proposed with this permit modification that is subject to public comment during the public notice period. All other permit monitoring requirments
remain unopened and unchanged as appropriate.

that representative values are being obtained. If the rate of discharge is controlled, the rate and duration of discharge shall be reported.*cTDS discharges shall initially be limited
to 1200 mg/L as a daily maximum concentration. If the effluent concentration is greater than 1200 mg/L, then the TDS discharges shall be limited to a loading of 231 lbs/day loading as
a maximum monthly average in lieu of the initial concentration limitation. *dA visual inspection for any oil and grease sheen, sanitary wastes, floating solids, and visible foam shall
be performed at least once per month at Outfall 005-B. There shall be no visible sheen, floating solids, or visible foam in other than trace amounts upon any discharges and there shall
be no discharge of any sanitary wastes at any time. If a sheen is observed anytime at Outfall 005-B, then a sample of the effluent shall be collected immediately thereafter and the oil
and grease shall not exceed 10 mg/L in concentration. *eTurbidity monitoring shall be conducted monthly whenever possible during discharge events to document that there is not an increase
of more than 10 NTU over the receiving waters, if applicable.PERMIT DURATIONIt is recommended that this modified permit be effective for the remainder of the five (5) year permit cycle,
which is set to expire at midnight on March 31, 2026. Permit Drafted and reviewed by:Jeff Studenka, Discharge Permit WriterLonnie Shull, Biomonitoring WET Coordinator Utah Division of
