Agency using chemical mask to cover sulfurous smell in Boston Heights
By Bob Downing
Beacon Journal staff writer
Published on Saturday, Jun 06, 2009
Work was under way Friday to eliminate foul odors escaping from a giant oil storage tank in northern Summit County.
The initial report is the chemical treatment was working and odors from the tank off East Hines Road near state Route 8 in Boston Heights were diminishing, said Jim Irwin of the Ohio Environmental Protection Agency.
That should provide relief for neighbors within a half-mile radius of the Heartland Petroleum tank at Dyna Guard/Gillota Inc. tank, he said.
Workers were fogging a specially made chemical produced by a Texas company, Baker Hughes Inc. of Houston. The chemical, with a slight bubble gum aroma, is designed to destroy the sulfur-laden fumes in the tank that are creating the odors that have plagued residents for three weeks.
The effort to curtail the odors came after two other attempts failed.
The foul smell can be detected by most people at concentrations of 1 to 2 parts per billion, Irwin said.
The concentrations in the oil inside the tank are about 25 parts per million, and the fumes have levels of 1 to 2 parts per million significantly higher than the levels at which the smells can be detected, Irwin said.
The fumes are offensive but are not a health threat, he said.
The problem started May 22, when 14,000 gallons of oil-field compressor oil were loaded into the mostly empty tank, Irwin said.
The tank's internal floating lid did not properly seal and the vapors have continued to escape, via vents in the tank, he said.
Efforts to dilute the compressor oil with crankcase oil failed, as did the use of a chemical masking agent, he said.
The compressor oil was moved into another Boston Heights storage tank where the floating lid is working. Odors have not been a problem there, Irwin said.
Oil-field compressor oil is recycled as fuel in the steel industry or as asphalt burner fuels.
