2. (b) The owner or operator of a source operating multiple combustion devices that share a common fuel source shall maintain records on a monthly basis of all operational data needed to estimate the distribution of the fuel combusted and emissions from each combustion device.

3. (c) The owner or operator of a combustion device shall maintain records of the following characteristics for each fuel combusted in the device:

   1. (1) For coal, on a monthly basis as follows:

      1. a. Ash content;
      2. b. BTU content of fuel; and
      3. c. Weight percent of sulfur;

   2. (2) For solid fuels other than coal, No. 6 oil, No. 5 oil, used oil, crude oil, and any liquid fuel not having a federal or state sulfur standard:

      1. a. Records showing the maximum weight percentage sulfur and quantity of each fuel delivery received; and

      2. b. Records showing either:

         1. 1. The analytical method used and the specific fuel analysis results of the shipment or consignment from which the delivery came; or

         2. 2. Delivery records sufficient to allow for traceability of the analytical results corresponding to each delivery received by the stationary source, showing:

            1. (i) The date of delivery;
            2. (ii) The type of fuel; and
            3. (iii) The name, address, and telephone number of the company making the delivery;
   3. (3) For any liquid fuel other than those listed in (2), above, either the records identified in (2), above, or a written statement from the fuel supplier that the sulfur content of the fuel as delivered does not exceed state or federal standards for that fuel; and

   4. (4) For gaseous fuels other than natural gas or propane, on a monthly basis:

      1. a. Sulfur content by weight or volume of fuel; and
      2. b. BTU content of fuel.
