NJDEP releases updates to Extractable Petroleum Hydrocarbon (EPH) Analysis (August 9, 2010 Revision)

On August 9, 2010, the New Jersey Department of Environmental Protection (NJEP) issued revised protocols for the analysis of samples collected from certain petroleum contaminated sites. These protocols, which become effective on September 1, 2010, require Extractable Petroleum Hydrocarbon (EPH) analysis on qualifying sites unless a Remedial Action Work Plan or Remedial Action Report has been approved by NJDEP or filed by a Licensed Site Remediation Professional prior to that date. (http://www.nj.gov/dep/srp/guidance/srra/eph_phasein.pdf)

This method, known as “EPH” has been designed to comply with NJDEP’s obligation to develop health based criteria for site remediation efforts. The EPH method includes a sample extract fractionation procedure that separates the petroleum content into specific carbon ranges. The fractionation data is loaded into a “calculator” (available from Accutest as an electronic data deliverable (EDD)) which enables the user to assess health impacts and make decisions regarding site remediation.

The August 9, 2010 version of the EPH method contains two significant components that rely on a clear understanding of the site history and the types of petroleum products contained in the on-site storage tanks as follows:

Category 1 tanks (Fuel Oil #2 and/or Diesel Fuel) do not require fractionation. The analytical result is reported as a single value for the carbon range of C9-C40. Consultants have the option of only reporting ranges C9-C28 if “no significant peaks are present after C28”. To facilitate data reporting, Accutest will report non-fractionated EPH results as C9-C28, C28-C40, and C9-C40.

Category 2 tanks (Fuel Oil #4, #6, Bunker, Crude Oil, Waste Oil, Unknowns, etc.) may first be screened via the non-fractionation EPH method. If the result is <1,700mg/kg, fractionation is not required. (See EPH Protocol: http://www.nj.gov/dep/srp/guidance/srra/eph_protocol.pdf). If the value is greater than 1,700 mg/kg, fractionation may be required.

To address these options, the following EPH products are available at Accutest Laboratories:

Product Description Product Code
Non-fractionated EPH
Non-fractionated EPH spiked for future fractionation
Contingent fractionation EPH analysis
Full Fractionation EPH analysis

In many cases, contingent analysis may be necessary depending upon the results of the initial analysis selected. (See the Technical Requirements Table 2.1 for guidance). Contingent analysis requires accelerated turnaround of the initial EPH analysis to satisfy the fourteen (14) day extraction holding time for soil samples. If multiple contingencies are needed, close coordination with your Accutest Project Manager is essential to assure that all method holding times are achieved.

Accutest provides the complete report deliverable required by NJDEP. In addition, Accutest will provide the Fractionated EPH data in the NJDEP calculator format if fractionation is required. To operate the calculator, the client will simply enter the type of tank (residential or non-residential) before initiating the calculate function. The calculator is also available as an EDD.

Accutest appreciates the opportunity to serve your analytical needs. Please contact your Accutest Project Manager or Business Development Manager for additional details and pricing information. Accutest has also prepared a detailed presentation on the method and protocol that may be scheduled through your Business Development Manager.
