KEMRON would like to recognize and congratulate its Safety Light Superfund Site Team on a HUGE safety achievement! The team has worked more than 114,000 hours without an OSHA recordable or incident. This includes approximately 41,500 hours for radiation subcontractors on site and the removal and transport of 1800 loads of radioactive material. This strong safety record over the course of six years demonstrates the Safety Light crew’s dedication and commitment to the protection of worker safety on this very complicated project. KEMRON thanks the Safety Light Team – Dave Tiedman, Heather Garrison, Dan Jones, Guy Smith and Zach Smith. Safety Light is a $29M radiological ongoing cleanup under a contract with EPA Region 3.

Large scale water treatment system optimization generates significant cost savings

KEMRON, under contract to USEPA, reengineered the water treatment process at the Mississippi Phosphate Corporation Superfund Site to accelerate treatment and maximize throughput. Water management volumes from low pH (<2) leachate and rainfall coming in contact with the gypsum stacks on this 400 acre site exceeds 1.5 billion gallons since KEMRON took over management. One inch of rain fall generates 9 million gallons of low pH contact water. The existing treatment process was able to effectively treat 1.5 million gallons a day. Through a series of modifications to include construction of mixing and settling ponds, KEMRON increased the treatment capacity to 4 million gallons per day.

KEMRON further reengineered the treatment process by installing an in-line mixing operation that introduces spent lime slurry from the mechanical plant into the low pH water before piping the lime slurry three miles to a series of mixing and settling ponds. This provided a marked improvement to pH adjustment through a much shorter treatment time frame further increasing overall efficiency by 20%. Cost savings in reduced quick lime are $22,000 per month. Savings on total treatment costs are in excess of $2.5M per year.

Don Rigger joins KEMRON

Don Rigger is the most recent addition to the KEMRON team in the role of Program Manager. Don joins KEMRON from EPA Region 4 after a 31-year career in the Superfund program. For his first 12 years at EPA, Don served as an On-Scene Coordinator (OSC) in the Emergency Response program where he managed removal actions and responded to environmental emergencies. After a few years in a supervisory role in Emergency Response, Don transitioned to a program management role in the Region 4 Superfund Remedial program. In that role, Don had two primary management responsibilities: Region 4’s site assessment program which adds new sites to the National Priorities List (NPL), and Region 4’s remedial program which investigates and remediates NPL sites across the Southeast.

Don’s project management portfolio as an OSC includes the Jackson County Pesticide Site in the late 1990’s which was, at that time, the most expensive removal action in the history of EPA’s Superfund program. Under Don’s leadership, Region 4’s remedial program built a strong reputation for moving sites quickly and cost effectively through the Superfund pipeline from Remedial Investigation to cleanup completion.

Prior to joining EPA, Don served brief stints in the oil/gas exploration business and geotechnical consulting. He hold a BS degree in geology from Washington and Lee University and an MBA from Georgia State.
