GRAND FORKS (AP) -- Officials say further study is needed to determine the extent of gasoline and diesel fuel underneath the parking lot by Grand Forks' old Civic Auditorium.
An apartment complex is planned for the site, and the fuel contamination could increase the $4.6 million cost.
Developers at MetroPlains have agreed to pay for the additional study and as much as $40,000 for cleanup. If the cost exceeds that, the St. Paul, Minn.-based firm will seek city funding.
City leaders have been keen to get land at and around the long-vacant auditorium privately developed and back on the tax rolls. The city plans to give the parking lot to MetroPlains if it builds the low-rent apartment complex.
