The LSPA received the following email from MassDEP on Thursday, January 23, 2020. 

Massachusetts Department of Environmental Protection has updated its Method for the Determination of Extractable Petroleum Hydrocarbons (EPH) and the corresponding CAM protocol, WSC-CAM-IVB, Quality Control Requirements and Performance Standards for the Analysis of Extractable Petroleum Hydrocarbons (EPH) in Support of Response Actions under the Massachusetts Contingency Plan.  The updates include revised holding times when samples are frozen, clarifications on the peak integration process during calibration, and a series of other minor revisions and clarifications.  A complete list of the updates is provided in the preface of the revised method.  The revised method may be found here

Laboratories that are currently performing EPH must make the necessary adjustments to implement the changes to the method on or before March 1, 2020 to comply with the method requirements and certify that the method is being performed in conformance with the CAM protocol, found here.  If you have questions about the revised method or CAM protocol, you may contact MassDEP at [email protected].
