RE: 2015 Hazardous Waste Biennial Report

To whom it may concern:

According to our records, your facility was listed as a Large Quantity Generator (LQG) of hazardous waste, a
hazardous waste Treatment, Storage, and Disposal (TSD) facility, or both, for some or all of 2015. All LQGs and
TSDs are required to submit a biennial report each even numbered year for their generator or facility activities
during the previous year. Your biennial report, covering calendar year 2015, must be submitted to this office by
March 1, 2016.

For electronic submittals, the Division is once again using the BRState software from Florida which can be found
at: "http://www.dep.state.fl.us/waste/categories/hazardous/pages/brs_data.htm."

Forms and instructions can be found at:
"http://www.epa.gov/epawaste/inforesources/data/biennialreport/index.htm”

All applicable information on the Site Identification (SI) Form, GM Form and WR Form must be completed. The
OI Form is not required by the State of Utah. Please note that, if the report is compiled using the Florida
software, the signed SI Form must be submitted as a hard copy along with a CD containing all other data.

If your facility was not a LQG or TSD during any part of 2015 and you wish to update your generator status,
please submit an updated SI Form.

If you have any questions, please call Carlee Christoffersen at [phone].

Sincerely,

Scott T. Anderson, Director
Division of Waste Management and Radiation Control
