EPA Five-Year Review
Semi-Annual Report



January 2017  

The Petro-Processors, Inc. site remediation activities continued to progress towards site closure during the past year.

NPC completed long term monitoring activities at the Brooklawn and Scenic Operable Units and submitted reports to the regulatory agencies which were subsequently approved.  Each of the selected remedies for the impacted environmental media was found to be protective of human health and the environment.  Subsurface conditions in the alluvial sediments at the Brooklawn OU continue to be supportive of the anaerobic biodegradation processes necessary to reduce groundwater contaminant concentrations upgradient of the point of compliance monitor wells.  Enhanced in-situ reductive dechlorination is the approved remedial action at the Scenic OU.  Remedial injections were completed at the source and distal treatment zones to promote and sustain geochemical conditions necessary for enhanced reductive dechlorination. During 2017, remedial injections are planned at the near-source treatment zone.

An interim remedial action to install two extraction wells downgradient of the distal treatment zone to allow activated carbon treatment of the downgradient plume was initiated in 2016.  This interim remedial action will continue in 2017.  Groundwater investigations were completed in December 2016, to evaluate potential contaminant pathways north of the distal treatment zone.  A remedial planning activities report will be submitted in the first quarter of 2017 to present the findings and address any actions if necessary.

An updated groundwater flow and solute transport model for the Scenic OU is anticipated to be completed in the first quarter of 2017. In the second quarter of this year an update to the Brooklawn groundwater model will be prepared to evaluate contaminant degradation rates upgradient of the point of compliance monitor wells.

EPA completed its third five-year review of the remedial actions implemented at the Petro-Processors, Inc. site in 2016.  The report concluded that the selected remedies at the site are protective of human health and the environment.

The site completed 16 years and over 638,000 man-hours with no recordable injuries.

Details of all approved plans can be inspected at the office of NPC Services, Inc. on Brooklawn Drive or at the Louisiana Department of Environmental Quality. We welcome your questions or comments at any time.
