Last Call: GreenHunter Energy shares slide

The stock dropped 80 cents, or 5.4 percent, to $14 in late afternoon trading.

GreenHunter said Monday that the storm, which slammed into Houston earlier this month, destroyed the refinery's office buildings, and many electrical panels, pumps and motors.

The water also floated several storage tanks and led to the disposal of feedstock and chemicals.

GreenHunter said that insurance will likely cover most of the damage.

Meanwhile, the broader markets dropped sharply Monday after the House of Representatives rejected a $700 billion bailout of the financial sector.

Representatives voted 228-205 against the bill, with 95 Democrats and 133 Republicans opposing the plan and 140 Democrats and 65 Republicans supporting it.
