Leaaf Environmental, LLC (Leaaf) was contracted by the Jefferson Parish Economic Development Commission (JEDCO) to provide Brownfields services funded though their Environmental Protection Agency (EPA) Brownfields Coalition Assessment Grant at the JM3 and JM5 Property.
The approximately 12-acres site was industrially developed in the early 1950s as an expansion to a portion of the original John-Manville Facility, a facility that manufactured products containing asbestos for use in roofing, flooring, and piping. The JM3-JM5 site was approved for further environmental investigation for three structures and various debris piles based on the age of the buildings and previous use of the property as identified in a Phase I Environmental Site Assessment (ESA).
Leaaf developed the strategy for identifying and quantifying asbestos-containing materials (ACMs) in the development of a Work Plan and Quality Assurance Project Plan (QAPP). A site-specific Health and Safety Plan (HASP) was also prepared for the project. After approval of the Work Plan and QAPP, Leaaf’s Louisiana Department of Environmental Quality (LEDQ)-certified Asbestos Inspectors conducted a Destructive Asbestos Survey to obtain bulk samples of suspect ACMs in the area identified by the Client based on the Phase I ESA. Samples were sent to a Louisiana Environmental Laboratory Accreditation Program (LELAP) accredited laboratory for polarized light microscopy (PLM) analysis. Based on the laboratory results, Leaaf confirmed the presence or absence of ACM at the site to determine quantities of confirmed ACM to assist in identifying future remedial needs at the site during future demolitions and redevelopment activities. A report was prepared presenting the results of the survey that included conclusions and recommendations.
