15A NCAC 02D .1207 CONICAL INCINERATORS



(a) Purpose. The purpose of this Rule is to set forth the requirements of the Commission relating to the use of conical incinerators in the burning of wood and agricultural waste. (b) Scope. This Rule shall apply to all conical incinerators which are designed to incinerate wood and agricultural waste. (c) Each conical incinerator subject to this Rule shall be equipped and maintained with:



(1)



(2) (3)



an underfire and an overfire forced air system and variable damper which is automatically controlled to ensure the optimum temperature range for the complete combustion of the amount and type of material waste being charged into the incinerator; a temperature recorder for continuously recording the temperature of the exit gas; a feed system capable of delivering the waste to be burned at a sufficiently uniform rate to prevent temperature from dropping below 800oF during normal operation, with the exception of one startup and one shutdown per day.



(d) The owner of the conical incinerator shall monitor and report ambient particulate concentrations using the appropriate method specified in 40 CFR Part 50 with the frequency specified in 40 CFR Part 58. The Director may require more frequent monitoring if measured particulate concentrations exceed the 24-hour concentration allowed under 15A NCAC 2D .0400. The owner or operator shall report the monitoring data quarterly to the Division. (e) In no case shall the ambient air quality standards as defined in Section .0400 of this Subchapter be exceeded. (f) The conical incinerator shall not violate the opacity standards in Rule .0521 of this Subchapter. (g) The distance a conical incinerator is located and operated from the nearest structure(s) in which people live or work shall be optimized to prevent air quality impact and shall be subject to approval by the Commission. (h) New conical incinerators shall be in compliance with this Rule on startup.
