As of 1:00 p.m. – July 13

Rochester Fire Chief Michael Mamone tells BeaverCountian.com all shelter in place orders have been lifted. All roads are now reopened, with the exception of the New York Avenue ramp that leads down toward the area of the bowling alley.

“We did not have a rekindle today, there was a second fire in a 20 yard roll-off dumpster that wasn’t a part of the original incident, but was in the exact same area,” Mamone said.

Mamone said the situation is now under control and officials will be meeting soon on a plan moving forward.

“As of right now we are taking all precautions with DEP and contractors to make sure another release does not occur. DEP has a site safety plan from the remediation work they were doing … We think that plan is working right now.”

Mamone praised his men, who he said are very tired after a long night’s work. He expects them to be able to get some sleep soon. Mamone also praised the work of other crews from throughout the county.

“We are using a lot of mutual aid from other towns.”

Mamone said there are still stores of hazardous materials on site, with chlorine continuing to be the substance of greatest concern. Although he does not anticipate another release, he said it remains a possibility.

“I don’t expect there to be fire crews down there much longer, but I expect there to be contractors and folks responsible for the building there moving forward. They have been there since last night and they are the ones who first saw the fire and called it in.”

No injuries were reported as a result of the incidents.

Crews continue to monitor the air quality to assure the safety of the public.

Ya what are the repercussions of this chlorine fire and these chemicals that are spewing into the air does anybody know are they going to tell us the truth how poisonous it really is probably not until it’s too late very sad day.


The building is owned, for less than a week, by the DEP. The DEP is investigating this. Surely they researched previous ownership. Someone had to know those pellets were there for 8 years, which is dangerous by itself.


Well-done to commissioner Edgley for being on the spot. I wish she had been wearing a mask tho.


The area of chemical threat was up to five miles from the fire. The projected blast area is up to five miles from the cracker plant, and up to 20 miles of fallout threat. I hope someone is taking notes and planning for that eventuality, if it ever comes. It will take more than the current emergency evacuation plans.


raven, next time shell holds one of those ” community meetings”. you outa go. it’s all PR about planting flowers. ask a question about bophal india and the chance of a local repeat, and you will get more smoke blown up your ass than answers. john paul, PLEASE attend too!
