WENY (Watkins Glen, NY) -- A local environmental firm is looking into the history of spills at Crestwood Midstream.

Toxics Targeting says they obtained Department of Environmental Conservation documents about spills that have occurred at the proposed Liquid Petroleum Gas storage site.

An environmental database firm in Ithaca, Toxics Targeting, released information they say they obtained from the Department of Environmental Conservation about previous spills at the site of Crestwood Midstream's proposed Liquid Petroleum Gas storage facility.

Their documents show 18 spills have occurred dating back to 1974.

However, Crestwood has owned the property since 2008.

"So over the course of more than 40 years we've seen the release of petroleum. We've seen releases of brine, which is toxic. It can kill vegetation. It can kill fish. Many of these problems were never cleaned up to applicable state standards. Much of the contamination impacted Seneca Lake," said Walter Hang, President of Toxics Targeting.

Of the 18 spills, Toxics Targeting says some were minor and affected the surface of Seneca Lake.

They say other spills released upwards of 470-thousand gallons of brine.

"So given those problems and given the state's inability to prevent problems and to clean them up to applicable state standards, we're today calling on Governor Cuomo not to authorize any gas storage permits at this site," said Walter Hang, President of Toxics Targeting.

Now just last week, WENY News exclusively obtained a letter from the DEC that said quote "department staff continues to assert that the project meets all applicable environmental statutory and regulatory standards."

WENY News reached out to Crestwood who said:

"We cannot speak to incidents that occurred before we bought US Salt in 2008. We knew that significant catch-up investment would be required, and we have spent tens of millions to upgrade and modernize the plant operations. Although our goal is an incident-free workplace, the incidents that have occurred since we finished replacing the brine pipeline system in 2013 have been minor. Despite what this group would like you to believe, there is nothing nefarious or catastrophic here - the state's experts had this data before strongly endorsing our propane storage project."
