General Requirements. (If selling Artificial Firewood, move to Section g. below). a. Heat Treatment: The State of Michigan’s preferred offering of firewood is that it has been heat treated to 140° Fahrenheit for 60 minutes. i. The Department strongly prefers all firewood utilized on state land be heat treated in a USDA / APHIS certified kiln per Heat Treatment Schedule T314-c at 160º Fahrenheit for 75 minutes (Asian Longhorn Beetle) or Treatment Schedule T314-a at 140º Fahrenheit for 60 minutes (Emerald Ash Borer, Walnut Twig Beetle and Hemlock Woolly Adelgid). ii. The Contractor will make efforts to convert to heat treated firewood. iii. For kiln certification requirements or additional information on heat treatment schedules, please go to www.aphis.usda.gov. iv. If a producer is certified by the USDA under the spongy moth quarantine, they are required to provide a report to the Department upon request that provides evidence of heat treatment to 140° Fahrenheit for 60 minutes (meets Michigan qualifications). b. Prevention of Invasive Species and Disease: Contractor shall prevent the spread of invasive species and disease in the firewood through the following MINIMAL PROCEDURES: i. Non-heat-treated firewood should be obtained and processed by the Contractor within the same county or 50 miles of the delivery location. The State defines the delivery location as the approximate center of the Park or Recreation Area. The transportation distance will not violate any Federal or State EAB (or other species) quarantine restrictions that may be in place. Non-heat-treated firewood may be moved fifty (50) miles within the EAB quarantine area (per National Firewood Task Force Recommendations), but must NOT be moved outside the quarantine area, even if the delivery location is within 50 miles; AND ii. Contractor shall verify that any wood sourced will not violate any established quarantine areas; AND iii. Non-heat-treated firewood should have had at least one (1) full year to dry (season) prior to transport to delivery location to help prevent the spread of oak wilt transmission, avoid wood infestation by exotic and native insects, and improve firewood quality; AND iv. To avoid violation of federal interstate restrictions on the movement of wood or wood products, non-heattreated firewood should be obtained and originate within the State of Michigan and certify this requirement annually by submitting a completed Statement of Wood Origin (see Attachment B).
