Triangle Oil and the West Wind Truck Stop are being sued by the U.S. Department of Labor, which contends the companies improperly lent pension plan funds.

Defendants in the suit are Triangle Oil President Douglas J. Allred and his wife, Geraldine; Lyle Nelson; Dean Kent; and the estate of the late Sheldon E. Christensen.

In the suit, the Labor Department accuses Triangle Oil pension fund trustees of violating the Employment Retirement Income Security Act of 1974 by improperly lending pension plan funds.

The trustees beached their duties by making repeated extensions of credit to an individual even though that person was already delinquent on prior loans, the suit says. The trustees also failed to take prompt action to collect, it says.

The suit also contends the pension fund made loans between 1982 and 1986 to Allred Investment Co. for purchase of property in Tremonton, despite the act's prohibitions on loans between a plan and people who are parties in interest to the plan.

Allred Investment was involuntarily dissolved by the state on Dec. 31, 1982, for failure to file an annual report, according to Utah Department of Business Regulation records.

The government is asking U.S. District Judge Bruce Jenkins to:

--Appoint an independent fiduciary to manage the pension fund.

__Rescind all prohibited transactions.

--Order the defendants to reimburse plan losses.

A federal court trial date has not been set.
