Units combusting tires or fuel derived from <br />tires. A waste combustor burning a single-item waste stream <br />tires or fuel derived from tires is not subject to parts <br />7011.1201 to 7011.1290 if the owner or operator notifies the <br />commissioner in writing of its intent to combust only tires, <br />provides data documenting that the unit qualifies for this <br />exemption. <br />of <br />and <br />Subp. 2b. Units combusting waste contaminated with used <br />oil. An owner of a solid-fuel-fired indirect or direct heating <br />source burning fossil fuel with only wastes contaminated with <br />used oil generated by the owner is not subject to parts <br />7011.1201 to 7011.1290. <br />Subp. 3. Exemptions from standards of performance. <br />Crematoria, pathological waste combustors, and waste combustors <br />used solely for the disposal of animal carcasses are exempt from <br />the requirements of parts 7011.1210 to 7011.1290, and shall meet <br />the conditions of this subpart. <br />A. No owner or operator of a crematorium, <br />pathological waste combustor unit, or waste combustor unit used <br />solely for the disposal of animal carcasses shall cause to be <br />emitted into the atmosphere gases which are greater than 20 <br />percent opacity. <br />B. Waste combustor owners and operators shall install <br />and operate an afterburner which maintains flue gases at 1,200 <br />degrees Fahrenheit for at least 0.3 seconds. <br />C. Ash shall be stored and transported in such a <br />manner to prevent avoidable amounts of particulate matter to <br />become airborne. <br />�Subp. 4. Standards.

Fugitive emissions standards applicable to ash <br />conveying systems do not apply during maintenance and repair of <br />ash conveying systems. "Malfunction" means any sudden and <br />unavoidable failure of air pollution control equipment or <br />process equipment or of a process to operate in a normal or <br />usual manner.
