Georgia Underground Storage Tank Program, State of Georgia

KEMRON is in the tenth year of a multi-year ID/IQ contract with the Georgia Environmental Protection Division (GAEPD) for high priority sites which require site investigation, corrective action plan (CAP) preparation, emergency response and remedial system design, installation and O & M. KEMRON has executed several hundred TOs under this contract including services at 48 different sites. KEMRON is a four time incumbent on this contract. Many of the task orders are fixed price and/or performance based contracts. The following represent project experience under this contract.

Circle M Site. KEMRON, operating under a fixed price, performance based contract of $1 million, was able to complete the investigation, design, remedial system installation and final cleanup on this environmentally and politically complex site on time and with only an additional $29,928. The minor budget exceedance is remarkable in light of the fact that five distinct plumes were identified during cleanup incorporate into this TO and remediated. In fact, one of the plumes, from an adjacent site, was eligible for an additional $1 million.

"KEMRON's sites reach completion faster than any other contractor we have used, on average. Their work is superb. The EPD relies on them for assistance in especially difficult or threatening sites."

- GA EPD

This site is characterized by a substantial gasoline free product plume and thick smear zone resulting from multiple UST releases. Water supply wells are within the radii of concern, but none were initially considered to be hydraulically connected to the dissolved phase plume. However, an updated receptor survey identified a recently refurbished municipal water supply. The presence of this well along with an extensive free product smear zone raised concerns about vertical migration of dissolved BTEX into the underlying bedrock aquifer. Investigation activities included the installation and sampling of 20 groundwater monitoring wells and soil borings.

KEMRON conducted risk assessment services to include fate and transport modeling and aquifer characterization; and development of a saprolite / bedrock model allowing calculation of area-weighted ACL’s protective of the bedrock aquifer KEMRON demonstrated the plume was effected by the public well pumping cycles. The high risk to the nearby receptor necessitated immediate preparation of the CAP. All remedial cleanup goals were achieved and the site has been issued No Further Action.

Quick Stop Remediation. KEMRON, operating under a PBC TO that schedule payment milestones of 40% at system installation (RIP), 40% at achievement of cleanup goals and 20% at NFA, met our clean objects one year ahead of schedule.

Rockmart Remediation. KEMRON, again operating under a PCB TO, was able to complete the remediation at this site in eight months (16 months ahead of schedule). We have requested an NFA for this site.

Roswell Road Site Remediation. KEMRON, operating under a design / build PBC TO, has designed a high efficiency dual phased vacuum extraction system for this site. The cleanup is complicated by the size and complexity of the plume. The plume extends below an adjacent business and below two large residential multi-family housing units. The plume of petroleum hydrocarbons is also fully mixed with a plume of chlorinated solvents emanating from an adjacent owner’s property. KEMRON’s performance based design incorporates both plumes and required system upgrades and modifications to meet chemical treatment requirements.

Mobile Treatment System – KEMVAC. KEMRON designed, built and operated a mobile dual phase vacuum extraction system and thermal oxidizer for remediation at four TO sites. The system eliminated the need for on-site equipment, long-term operation and business disruption. KEMVAC proved to be highly successful and cost effective and reduced cleanup schedules significantly.

Adrian Site. KEMRON, operating under a PCB TO, completing a removal effort, installed a treatment system, installed horizontal extraction wells below a US interstate, slip lined feet of sewer line and extended the sewer line 300 feet. All work was completed in six weeks, four weeks ahead of schedule.
