Using oilfield brine to fight icy roads can cut costs for cities and townships, but it raises environmental concerns for some.
Saltier than ocean water and used to treat roads in the winter, brine saves cities and townships money on salt and labor. Some government entities get brine for free.
The Ohio Department of Natural Resources defines brine as any water pumped from a producing oil and gas well.
Joyce Miller, spokeswoman for the Ohio Department of Transportation's District 3 that covers Crawford and Richland counties, said brine is used to pretreat all the district's routes.
"Brine is used as a pretreatment before a snow event, while salt is used after the snow to treat and clean the roads," Miller said......
In Ohio, 202 cities, villages and townships in 34 counties have approved or continued use of brine on their roads. Eighteen county governments have signed on.
Those that elect to use brine can shave thousands of dollars off their annual road salt expenses. Brine, by virtue of its lower freezing point, also may be better than rock salt at preventing ice from forming on roads.
Oil and gas producers also benefit because they can save on the costs -- typically $3 to $4 per barrel (42 gallons) -- of injecting the brackish water underground, the only other approved end point for oilfield brine.
Almost 200 million gallons of brine were produced by Ohio wells in 2010, the last year of complete reporting available, according to the state's well database.
In 2010, 90 percent of brine and fracking fluid in the state was injected underground, a CentralOhio.com review found. The remaining 10 percent includes the amount reused in the drilling process and relatively tiny amounts stored or recycled at a water treatment plant. About 2 percent -- brine only, by law -- was spread on Ohio roads.
By my math 2% of 200,000,000 gallons is 4,000,000 gallons of produced brine used on roadways. Don't you wish you could do that with your produced brine and save all that disposal charge?
