13 & 14 October | Orlando, FL

A spill from a fuel tanker rollover generated an emergency response on a Florida roadway. The spill involved fuel impacts to the travel lanes, the embankment supporting the on ramp, and the retention pond at the toe of the embankment. Subsequent interim source removal activities included soil excavation, free-product recovery, multiphase extraction, and a series of chemical oxidation injections, performed as a remediation pilot study. As the cleanup progressed and a remedial action plan was being considered, a second spill event occurred at the same location 2.5 years after the first one. The second event underwent additional assessment, and two parties moved forward with a shared remediation design and implementation. The remediation plan implementation consisted of two chemical injection events into the shallow portion of contaminated groundwater. The first injection event consisted of a chemical oxidation reagent and the second event of injection of a mixture of chemical oxidation and biostimulation reagents. A third injection event consisted of a deeper injection interval with a biostimulation reagent only. This case study chronicles the implementation of multiple assessments and remediation implementations for multiple spill events for a similar location, for a site with multiple stakeholders and multiple constraints, including work alongside an active roadway and in advance of a proposed roadway construction corridor project.

Handex Consulting & Remediation – Southeast, LLC (HCR), more notably our Director, Irv Heath, has been diligently working with the Florida Petroleum Marketers Association (FPMA) and their attorneys, while serving as the FPMA Chair of the Environmental Committee. The long awaited Low Score Site Initiative (LSSI) was finally passed in the Florida Legislature on November 16, 2010.

Effective November 17, 2010, any site with a priority ranking score of 10 points or less may voluntarily participate in LSSI, whether or not the site is eligible for state restoration funding. The great news for business and property owners is that sites that are eligible for state restoration funding may receive payment of pre-approved costs, including 6 months of groundwater monitoring, not to exceed $30,000 for each site. Up to $10 million per fiscal year will be made available, on a first-come, first-serve basis. Through the assessment process, if the site meets the specified criteria, the Florida Department of Environmental Protection (FDEP) shall issue a determination of “No Further Action” acknowledging that minimal contamination is detected, the FDEP may issue a site rehabilitation completion order.

The intent of the LSSI program is to eliminate sites from the program; not fully assess the sites.  FDEP expects most sites to not require anywhere near $30,000 to get to closure.  Assessments will be streamlined to collect only enough data to determine if the site will qualify for Site Rehabilitation Completion Order (SRCO), No Further Action (NFA), or No Further Action with Conditions (NFAC). At the end of the first event the site owner will have an opportunity and be required to review the initial assessment data with the contractor and decide if they want to proceed toward an SRCO, NFA, or NFAC.  The interim deliverable will include a signed document by the property owner on which path they choose. If a site does not qualify for closure based on site conditions, then no deductibles will be collected and the site will go back onto the pre-approval list for future funding based on the score and funding thresholds.

The benefits for site and business owners that participate in the LSSI program include obtaining valuable information about the property for little to no cost to the site owner, potentially increasing the property’s value, as well as the closure from the site assessments that removes an “environmental cloud” from the property’s value.

LSSI is providing to be one more value added service for our clients here at HCR. For more information about LSSI, please do not hesitate to contact HCR with any questions.

Sludge & Dewatering

Dewatering is the removal of water from solid material or soil by wet classification, centrifugation, filtration, or similar solid-liquid separation processes, such as removal of residual liquid from a filter cake by a filter press as part of various industrial processes. Sludge refers to the residual, semi-solid material left from industrial wastewater, or sewage treatment processes. It can also refer to the settled suspension obtained from conventional drinking water treatment, and numerous other industrial processes.

HCR’s Dewatering Services

Handex Industrial Services, LLC (HIS) is a nationwide provider of Pumping, Dredging, Sludge Dewatering and Treatment for industrial and process wastes. This operation includes a HAZWOPER trained and OSHA certified staff of experienced Project Managers, Operators, Technicians and Mechanics.

HIS specializes in the removal and pumping of sludge from lagoons, basins and tanks, utilizing Hydraulic Submersible Pumps, Pontoon Pumps and Floating Dredges.

Handex Industrial Services process over 40 million gallons of sludge annually, achieving volume reductions of up to 80%. The proprietary High Pressure Plate and Frame Filter Press treatment solutions HIS utilizes are widely regarded as the most cost effective for many RCRA Hazardous Waste Streams. This liquid/solid separation technology yields the greatest volume reduction, while generating the minimum quantity of waste residue. It returns recyclable sludge byproducts, including oils or metals that can be further reclaimed, refined or recycled. In many cases, HIS clients find that the value of the raw materials to the plant pays for the cost of the sludge dewatering service.

Waste Minimization

Handex Industrial Services utilization can increase waste minimization savings from less offsite transfer, which is about 80% volume reduction. Savings may also occur from reduced sludge removal and pre-treatment solutions, completely mobile and self-contained equipment for remote locations, treat-ability testing to achieve optimum process choice and filter acids and reduced disposal filtrate costs.

Tank Sludge Removal & Demotion

HIS performs specialized services that include the removal and processing of tank bottoms at oil refineries and industrial plants. Tank sludges processed by HIS include Crude Oil Tank sludge, F-037; API Separator sludge-048-K-052, Benzene contaminated sludges, DAF sludge storage, and mixed sludges.

In addition, HIS has extensive experience in safely managing tank dismantling, demolition and decommissioning for both Aboveground Storage Tanks (ASTs) and Underground Storage Tanks (USTs).

Green Remediation:  Performance, Cost, and Carbon Footprint Analysis of Chemical Injection Strategies and Implementations in South Florida

by

Timothy L. Harman, PE

General Manager

Handex Consulting & Remediation, LLC

(Presented at the 16^th Annual Florida Remediation Conference  held October 14-15, 2010 in Orlando, Florida)

ABSTRACT:  Historically, approaches to contaminated site closure in Florida have not fully considered sustainability concepts when making decisions regarding remediation strategy and technology selection.  Although these concepts are not new, an increasing focus on sustainability for environmental remediation is a result of Federal, State, and local government initiatives and policy directives.  For this presentation, several chemical injection implementations and case studies in South Florida will be profiled for remediation performance, cost effectiveness, and sustainability (green) metrics. 

Prevailing contemporary guidance for sustainability metrics include, at a minimum, energy use, air emissions, water impacts, materials use (materials management and waste reduction), and land and ecosystem protection.  Remediation strategies included chemical oxidation and biostimulation either in conjunction, or independent reagent application for treatment of petroleum hydrocarbon contaminants.  The chemical injections were performed within the last five years and in some cases were performed subsequent to conventional remediation strategies, such as air sparging and soil vapor extraction, thereby allowing for site specific comparison of metrics in relation to technology application and performance monitoring. 

With the benefit of hindsight, an increased awareness of sustainability concepts, and the development of green remediation metrics, we can evaluate and quantify the benefits of less intrusive remediation strategies within a current context of overall environmental and economic impacts.  While the prevention and remediation of contamination is inherently “green”, through the evaluation of these case studies we will be able to explore just how green purported “green” remediation strategies really are in comparison with conventionally utilized technologies within the context of quantifiable metrics rather than generic qualitative assumptions.
