Case Study of Dual Tanker Spill Events onto a Roadway Embankment with Assessment of Multiple Remediation Strategy Effectiveness and Carbon Footprint Analysis

17th Annual Florida Remediation Conference
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.

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.

LTNAM Updates

Long Term Natural Attenuation Monitoring (LTNAM) is referred to as passive remediation. It is a popular approach to risk management in the Petroleum Cleanup Program. LTNAM is cost effective in its approach and often provides clients with a budget friendly solution to environmentally impacted sites. Final updates for LTNAM can be found here:

Priority Score Funding

The DEP has determined that a downward score adjustment for the priority score funding threshold is prudent at this juncture. Therefore, effective January 3, 2011, the score has been adjusted from 56 to 49. The Petroleum Cleanup Preapproval Program spending procedures for fiscal year 2010-2011 dated July 1, 2010 apply. Questions regarding these procedures should be directed to either Charles Williams @ (850) 245-8863 or Mike Ashey @ (850) 245-8821.
