THE STATE OF MINNESOTA 

Introduction

            Natural gas arrived from Texas, via Illinois and here under control of the Northern Natural Gas System, owned by the Insull interests (North American Light & Power Company and United Light & Railways Company) along with Lone Star Gas Company, beginning in 1930.

            Minnesota DOT was early impacted by its discoveries, believed highest of all State transportation departments, of 11 FMGPs by 1988 (NCHRP Compendium 310, 1988). MNDOT responded to the challenge by developing a Policy Statement by year-end. Working cooperatively, Minnesota Pollution Control Agency (MPCA) moved to devise a basis for calculating cleanup Action Levels (1991) based on their potential factor of contribution toward contamination of ground water.
