Enough to heat about 350 homes a day is being dissolved and released. I pay about two hundred a month in the winter for gas alone,.. times 350=$7,000 a dayx30=$210,000 per month.
 Dec-may=6 months@$210,000.   $1,260,000 bucks if they wait till May.  
Plus the cost of the replacement gas, the lost taxes, the unknown affects on the whales etc.  
This line and the oil line running next to it run across the same rocky outcrop from what I read. They are the same age. How long before that nearby line of the same age, with oil in get a leak?  This is a symptom of what are likely to become systemic problems to the aging oil and gas pipes under our Cook Inlet.  I would say this warrants a closer look at what and when the latest checks were made to the conditions of the OTHER lines running to those old platforms being milked to the failure point?  If these guys can`t even inspect the extent/nature of a leak in just 80 feet of water, at will, at slack tide...well, winters can be pretty long here.
