EPA Five-Year Review
Semi-Annual Report



January 2018  

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. 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 near-source treatment zone to promote and sustain geochemical conditions necessary for enhanced reductive dechlorination. During 2018, remedial injections are planned at the near-source and distal treatment zones.

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, and continued through 2017.  This interim remedial action will continue in 2018.  Groundwater investigations were completed in December 2016, to evaluate potential contaminant pathways north of the distal treatment zone.  A remedial planning activities report was submitted in the second quarter of 2017, to present the findings and address any actions if necessary. This report was approved in the second quarter of 2017. Two additional extraction wells were installed downgradient of the distal treatment zone in 2017, these wells will allow for additional activated carbon treatment in the downgradient plume.

An updated groundwater flow and solute transport model for the Scenic OU is anticipated to be completed in 2018.  At the Brooklawn OU an update to the groundwater model is being prepared to evaluate contaminant degradation rates upgradient of the point of compliance monitor wells.

The site completed 17 years and over 652,000 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.
