MONTPELIER - Cumberland Farms will pay the state $150,000 in civil penalties for multiple violations related to monitoring of its underground gasoline storage tanks at 10 of its Vermont convenience stores, the Vermont Attorney General's office announced Friday.

Most of the 39 violations relate to Cumberland Farms' failure to conduct and maintain documentation of release detection monitoring of tanks and associated piping at a number of its stores, and failure to report to the Agency of Natural resources and investigate incidents involving release detection monitoring system alarms.

The Agency of Natural Resources discovered the violations during regular inspections of Cumberland Farms' facilities located in Barre, Fairlee, Lyndon, Montpelier, Morrisville, Northfield, Newport, St. Johnsbury, and Woodstock conducted between 2005 and 2010.

Under the court-approved settlement, Cumberland Farms admits 39 violations of the state's underground storage tank rules, will pay the state a civil penalty of $150,000, and will implement a compliance plan designed to ensure that all of its facilities remain in compliance with the law.
