(d) Fires shall be conducted under favorable weather conditions such as relatively calm winds not blowing toward populated areas. Fires shall not be conducted during temperature inversions or when an air pollution alert is in effect.
(e) Fires shall be conducted a minimum of 152 m (500 ft) from commercial or residential dwellings, power lines, or major roads.
(f) An air-curtained incinerator shall not be located within 300 m (1,000 ft) of a sanitary landfill or transfer station as defined in 329 IAC 1.5.
(g) The air-curtained incinerator shall be attended at all times during burning and until combustion is complete. Adequate fire fighting equipment shall be maintained at the site at all times during operation.
(h) If a fire creates an air pollution problem, a nuisance, or a fire hazard, such fire shall be immediately extinguished.
(i) The air-curtained incinerator and pit shall be maintained and operated in accordance with the manufacturer's specifications and recommendations.

(k) Material being loaded into the pit shall be picked up and dropped into the pit. At no time shall the material in the pit be permitted to project through the curtain of air while burning.
(l) All burning shall be in accordance with other State and local regulations, such as those of the local health department.
(m) The owner or operator or an air-curtained incinerator shall provide notifications in advance to the local fire department and local health department of the dates and times such incinerator will be in operation.

(v) The air-curtained incinerator shall not be at a higher elevation than the elevation of the opposite wall.
(w) The pit shall be enclosed on 4 sides. The walls shall be perpendicular to level ground. Burning will not be permitted in areas where a pit may not be constructed and maintained due to the presence of non-cohesive soils such as loose sand.
