NewFields LSRP Program Continues to Develop Technical Guidance
David Puchalski with NewFields’ New Jersey office was selected as the New Jersey Licensed Site Remedial Professional (LSRP) association representative for the Extractable Petroleum Hydrocarbon (EPH) technical subcommittee. The LSRP program allows an experienced environmental consultant to become licensed with the NJDEP and directly manage all aspects of an environmental project. The NJDEP provides technical guidance, scheduling oversight and auditing for individual cases. Other responsibilities are assumed by the LSRP including remedial investigation decisions, remedial actions, public involvement, protection of human health and case closure.
The EPH subcommittee is amending the 2010 guidance document that established an EPH concentration in soil that indicates the potential for non-aqueous phase liquid (NAPL) to exist in unsaturated soils. The current guidance provides only two indicator concentrations; 8,000 mg/kg for No. 2 fuel oil/ diesel fuel or 17,000 mg/kg for all other refined petroleum oils. While investigating various oil terminals, NewFields has identified multiple projects where the single concentration NAPL-indication is too conservative and too restrictive.
The amended guidance will provide a process for an LSRP to develop a site specific NAPL-indicator concentration. The LSRP will evaluate the physical characteristics of the released oil and the grain size characteristics of the unsaturated soil to calculate a site specific concentration. With the help of Jacob Oehrig (NewFields Atlanta), David is developing an Excel calculator that will be provided by the NJDEP to the regulated community.
