OTTAWA -- The West Virginia Division of Forestry worked last week to contain a forest fire in Boone County. Charlie Spencer with the WV Division of Forestry said that the fire spread to about 100 acres in the area around Stollings Branch, near Ottawa. By Monday evening, April 22, 2013, crews had the fire about 50 percent contained, according to Spencer. No homes were threatened by the fire, officials reported. Investigators believe the blaze was likely started by an arsonist. From March 1 through May 31, daytime burning is prohibited from the hours of 7 a.m. to 5 p.m. Outdoor burning is permitted only between the hours of 5 p.m. and 7 a.m. State law requires a ring or safety strip around outdoor fires to keep the fire from spreading into the woods. This safety strip must be cleared of all burnable material and be at least 10 feet wide completely around the debris pile. Additional requirements of the state's fire laws include staying on-site until the fire is completely extinguished, and only burning vegetative materials like leaves, brush and yard clippings. If you allow a fire you have started to escape and it causes a wildfire or forest fire, you will be subject to fines ranging from $100 to $1,000. An additional civil penalty of $200 also will be assessed against you, officials added.
