Former Saratoga Incinerator

Leaaf was engaged by the City of New Orleans Capital Projects Administration to perform soil remediation at the former Saratoga Street Incinerator.  The site historically housed two municipal incinerators from the 1930s to 1974 and was used as a solid waste transfer station from 1974 to 1986.  Leaaf developed a Louisiana Department of Environmental Quality (LDEQ) approved Corrective Action Plan (CAP) based on historical investigations conducted at the site prior to Leaaf's involvement in the City Contract.

Leaaf then completed the remediation of the site in accordance with the CAP. The work included the removal of lead and polycyclic aromatic hydrocarbons (PAHs) from seven separate areas within the former incinerator site.  Best management practices as part of a Stormwater Pollution Prevention Plan (SWPPP) were followed to ensure stormwater was not impacted as a result of remediation activities. Confirmatory soil samples were collected following excavation and sent to a third-party laboratory for analysis.  The Corrective Action Report (CAR) presenting the results of remediation activities was submitted in February 2021.  As a result of the soil remediation, all area of investigation concentrations in soil were below their respective limiting Risk Evaluation/Corrective Action Program (RECAP) standards based on a non-industrial land use scenario, including 95% Upper Confidence Level (UCL) calculations.  Leaaf recommended a No Further Action (NFA) determination for the property.

In addition to the remediation, due to public concern in the neighborhood, Leaaf collected air monitoring samples (real time dust and analytical based lead and PAHs) to document that the work had not increased the exposure of the residents to elevated levels of lead and/or PAH dust particles.

The property is planned for redevelopment into green infrastructure with dry stormwater detention ponds.  The work was performed in a manner that Leaaf completed the work plus additional excavation work on time and under the original budget.
