NR 484.10(33), which result in data at least as reliable as classification I-C-2, defined in ASTM D2234/D2234M-03e1 as automatic sampling - part stream cut - random spacing, and analyze these samples for ash content, sulfur content and heat content according to the applicable methods and procedures in s. NR 439.08(1).

2. Submit quarterly reports within 30 days following the end of each calendar quarter which include the following information for each week during the calendar quarter:

e. Weighted average sulfur dioxide emission rate in terms of pounds of sulfur dioxide per million Btu heat input from the coal burned.

(c) The owner or operator of a coal burning installation which has a coal burning rate equal to or greater than 10,000 tons per year but less than 100,000 tons per year shall sample coal and submit reports on coal quality in the following manner:
1. Perform coal sampling using the procedures in ASTM D2234/D2234M-03e1, incorporated by reference in s. NR 484.10(33), which result in data at least as reliable as classification II-D-2, defined in ASTM D2234/D2234M-03e1 as manual sampling - stationary coal sampling - random spacing, and analyze these samples for ash content, sulfur content and heat content according to the applicable methods and procedures in s. NR 439.08(1).

2. Submit quarterly reports within 30 days following the end of each calendar quarter which include the following information for each month during the calendar quarter:
a. The total quantity of coal burned expressed in tons.

b. Weighted average percent of the ash content of the coal burned.

c. Weighted average percent of the sulfur content of the coal burned.

d. Weighted average heat content expressed in Btu per pound of the coal burned.

e. Weighted average sulfur dioxide emission rate in terms of pounds of sulfur dioxide per million Btu heat input from the coal burned.
