[Code of Federal Regulations] [Title 40, Volume 24] [Revised as of July 1, 2003] From the U.S. Government Printing Office via GPO Access [CITE: 40CFR266.108] [Page 42-43] TITLE 40--PROTECTION OF ENVIRONMENT AGENCY (CONTINUED) PART 266--STANDARDS FOR THE MANAGEMENT OF SPECIFIC HAZARDOUS WASTES AND SPECIFIC TYPES OF HAZARDOUS WASTE MANAGEMENT FACILITIES--Table of Contents Subpart H--Hazardous Waste Burned in Boilers and Industrial Furnaces Sec. 266.108 Small quantity on-site burner exemption. (a) Exempt quantities. Owners and operators of facilities that burn hazardous waste in an on-site boiler or industrial furnace are exempt from the requirements of this subpart provided that: (1) The quantity of hazardous waste burned in a device for a calendar month does not exceed the limits provided in the following table based on the terrain-adjusted effective stack height as defined in Sec. 266.106(b)(3): Exempt Quantities for Small Quantity Burner Exemption ------------------------------------------------------------------------ Allowable Allowable hazardous hazardous waste Terrain-adjusted waste Terrain-adjusted effective burning effective stack burning stack height of device (meters) rate height of device rate (gallons/ (meters) (gallons/ month) month) ------------------------------------------------------------------------ 0 to 3.9....................... 0 40.0 to 44.9..... 210 4.0 to 5.9..................... 13 45.0 to 49.9..... 260 6.0 to 7.9..................... 18 50.0 to 54.9..... 330 8.0 to 9.9..................... 27 55.0 to 59.9..... 400 10.0 to 11.9................... 40 60.0 to 64.9..... 490 12.0 to 13.9................... 48 65.0 to 69.9..... 610 14.0 to 15.9................... 59 70.0 to 74.9..... 680 16.0 to 17.9................... 69 75.0 to 79.9..... 760 18.0 to 19.9................... 76 80.0 to 84.9..... 850 20.0 to 21.9................... 84 85.0 to 89.9..... 960 22.0 to 23.9................... 93 90.0 to 94.9..... 1,100 24.0 to 25.9................... 100 95.0 to 99.9..... 1,200 26.0 to 27.9................... 110 100.0 to 104.9... 1,300 28.0 to 29.9................... 130 105.0 to 109.9... 1,500 30.0 to 34.9................... 140 110.0 to 114.9... 1,700 35.0 to 39.9................... 170 115.0 or greater. 1,900 ------------------------------------------------------------------------ (2) The maximum hazardous waste firing rate does not exceed at any time 1 percent of the total fuel requirements for the device (hazardous waste plus other fuel) on a total heat input or mass input basis, whichever results in the lower mass feed rate of hazardous waste. (3) The hazardous waste has a minimum heating value of 5,000 Btu/lb, as generated; and (4) The hazardous waste fuel does not contain (and is not derived from) EPA Hazardous Waste Nos. F020, F021, F022, F023, F026, or F027. (b) Mixing with nonhazardous fuels. If hazardous waste fuel is mixed with a nonhazardous fuel, the quantity of hazardous waste before such mixing is used to comply with paragraph (a). (c) Multiple stacks. If an owner or operator burns hazardous waste in more than one on-site boiler or industrial furnace exempt under this section, the quantity limits provided by paragraph (a)(1) of this section are implemented according to the following equation: [GRAPHIC] [TIFF OMITTED] TC06NO91.004 [[Page 43]] where: n means the number of stacks; Actual Quantity Burned means the waste quantity burned per month in device ``i''; Allowable Quantity Burned means the maximum allowable exempt quantity for stack ``i'' from the table in (a)(1) above. Note: Hazardous wastes that are subject to the special requirements for small quantity generators under Sec. 261.5 of this chapter may be burned in an off-site device under the exemption provided by Sec. 266.108, but must be included in the quantity determination for the exemption. (d) Notification requirements. The owner or operator of facilities qualifying for the small quantity burner exemption under this section must provide a one-time signed, written notice to EPA indicating the following: (1) The combustion unit is operating as a small quantity burner of hazardous waste; (2) The owner and operator are in compliance with the requirements of this section; and (3) The maximum quantity of hazardous waste that the facility may burn per month as provided by Sec. 266.108(a)(1). (e) Recordkeeping requirements. The owner or operator must maintain at the facility for at least three years sufficient records documenting compliance with the hazardous waste quantity, firing rate, and heating value limits of this section. At a minimum, these records must indicate the quantity of hazardous waste and other fuel burned in each unit per calendar month, and the heating value of the hazardous waste.
