Section 225.265  Coal Analysis for Input Mercury Levels

a)         The owner or operator of an EGU complying with this Subpart B by means of Section 225.230(a)(2) or using input mercury levels (I_i) and complying by means of Section 225.230(b) or (d) or Section 225.232 must fulfill the following requirements:

1)         Perform daily sampling of the coal combusted in the EGU for mercury content.  The owner or operator of such EGU must collect a minimum of one 2-lb grab sample per day of operation from the belt feeders anywhere between the crusher house or breaker building and the boiler.  The sample must be taken in a manner that provides a representative mercury content for the coal burned on that day.

2)         Analyze the grab coal sample for the following:

A)        Determine the heat content using ASTM D5865-04 or an equivalent method approved in writing by the Agency.

B)        Determine the moisture content using ASTM D3173-03 or an equivalent method approved in writing by the Agency.

C)        Measure the mercury content using ASTM D6414-01, ASTM D3684-01, or an equivalent method approved in writing by the Agency.

3)         The owner or operator of multiple EGUs at the same source using the same crusher house or breaker building may take one sample per crusher house or breaker building, rather than one per EGU.

4)         The owner or operator of an EGU must use the data analyzed pursuant to subsection (b) of this Section to determine the mercury content in terms of lbs/trillion Btu.

b)         The owner or operator of an EGU that must conduct sampling and analysis of coal pursuant to subsection (a) of this Section must begin such activity by the following date:

1)         If the EGU is in daily service, at least 30 days before the start of the month for which such activity will be required.

2)         If the EGU is not in daily service, on the day that the EGU resumes operation.
