Notice - September 2013

A recent laboratory assessment determined that the Health and Environmental Testing Laboratory (HETL) is no longer certified to analyze compliance samples in soil and waters for volatile petroleum hydrocarbons (VPH). HETL is working to regain this certification.

Petroleum Clean Up

Introduction

Maine's underground and aboveground petroleum storage facilities located across the state store motor fuels and heating oil. In addition to spills associated with transporting and delivering fuel, the storage tanks and associated piping can fail due to corrosion, physical damage, inadequate maintenance and vandalism. The spilled petroleum can contaminate soil, groundwater and air and exposure to petroleum contaminated media can be harmful to ones health. DEP has guidelines to measure levels of petroleum contamination and determine the clean-up necessary to minimize risk to public health.

Written approval of clean up plans required. Oil discharges are required by Maine statute (38 MRSA §568) to be cleaned up to the satisfaction of the Commissioner. Maine statute also limits payments to reimburse applicants to the Maine Groundwater Oil Clean-up Fund to those clean up expenditures that are in accordance with a written agreement between the applicant and the Commissioner and which includes a remedial action plan and schedule (38 MRSA §568-A.4). Remedial action agreements are to be entered into before the start of clean up. For non-emergency response clean-ups, remedial action plans are expected to include a thorough evaluation of the feasible clean up alternatives and their cost effectiveness.

Fund Coverage Cost Guide: The Fund Coverage Cost Guide is intended to give guidance regarding what will be considered as eligible for payment or reimbursement from the Ground Water Oil Clean-Up Fund on a site where an applicant has been found eligible for coverage by the Fund program, under 38 M.R.S.A. Section 568-A. For further information, contact James Cumming in the Oil Remediation and Claims Unit at (207) 287-7860.

Petroleum Site Clean-up Guidelines: Updated November 20, 2009 (Effective December 1, 2009)- Remediation Guidelines for Petroleum Contaminated Sites in Maine (pdf format) - These risk-based guidelines apply to the investigation and clean-up of petroleum contaminated sites, including gasoline, aviation fuels, methyl tertiary butyl ether (MTBE), kerosene, #2 heating oil, other heating oils including heavy oils, diesel fuel, or other comparable petroleum hydrocarbons. It applies to DEP staff, potential responsible parties, Maine Ground Water Oil Clean-up Fund applicants, Voluntary Response Action Program applicants and others remediating oil sites in Maine. These guidelines go into effect on December 1, superseding on January 1, 2010 the Department’s “Procedural Guidelines for Establishing and Implementing Action Levels and Remediation Goals for the Remediation of Oil Contaminated Soil and Ground Water in Maine” (December 5, 2008), which are based on gasoline range organics (GRO) and diesel range organics (DRO). Both sets of guidelines will be in effect for one month to allow for the transition to the Volatile Petroleum Hydrocarbons (VPH) and Extractible Petroleum Hydrocarbons (EPH) approach used in the new guidelines.

Petroleum: Estimating EPH & VPH from DRO & GRO results. Development of Risk-Based Cleanup levels for Petroleum Hydrocarbons, Interim Final, Prepared for the Maine Department of Environmental Protection by MACTEC Engineering and Consulting, Inc. in April of 2010. This report presents correlations between diesel range organics (DRO) and gasoline range organics (GRO) to Extractible Petroleum Hydrocarbons (EPH) and Volatile Petroleum Hydrocarbons (VPH). These guidelines complement, and do not replace, the petroleum site clean-up guidelines (above), by in some cases allowing the use of DRO/GRO sample results with the EPH/VPH soil clean-up guidelines.
