Sec. 2.
(a) Owners or operators of coal sampling systems for sources with total coal-fired capacity greater than or equal to one thousand five hundred (1,500) million British thermal units (Btu) per hour actual heat input shall follow procedures specified in ASTM D2234-89*, "Standard Methods for Collection of a Gross Sample of Coal", unless otherwise provided in section 3 of this rule. Additionally, the coal sampling system shall meet the following requirements:
(b) Owners or operators of coal sampling systems for sources with total coal-fired capacity between one hundred (100) and one thousand five hundred (1,500) million Btu per hour actual heat input shall comply with requirements:
(c) Coal samples shall be prepared for analysis in accordance with procedures specified in ASTM D2013-86*, "Standard Method of Preparing Coal Samples for Analysis". The preparation of samples shall meet the following requirements:
(d) The heat content of coal samples shall be determined in accordance with procedures specified in ASTM D2015-95*, "Standard Test Method for Gross Calorific Value of Solid Fuel by the Adiabatic Bomb Calorimeter", or ASTM D3286-91A*, "Standard Test Method for Gross Calorific Value of Coal and Coke by the Isothermal Jacket Bomb Calorimeter". Restandardization requirements in Section 11 of both methods shall be followed. Precision requirements for repeatability shall be verified according to Section 16.1.1 of both methods at a minimum of once per week.
(e) The sulfur content of coal samples shall be determined according to procedures specified in ASTM D3177-89*, "Standard Test Methods for Total Sulfur in the Analysis Sample of Coal and Coke", or ASTM D4239-94*, "Standard Test Methods for Sulfur in the Analysis Sample of Coal and Coke Using High Temperature Tube Furnace Combustion Methods". Precision requirements for repeatability shall be verified according to ASTM D3177-89*, Section 13, or ASTM D4239-94, Section 18*, at a minimum of one (1) time per week. The laboratory that performs the analysis shall participate in an interlaboratory audit program using coal samples supplied by the department.
(f) The department may approve minor modifications to the coal sampling and analysis procedures at a source upon demonstration by the source owner or operator that the minor modifications are necessary to meet the requirements of this section.
