Current through Register Vol. 48, No. 28, July 12, 2024
A determination of non-compliance based on any subsection of
				  this Section shall not be refuted by evidence of compliance with any other
				  subsection.
a) Sulfur Dioxide
				Measurement. Measurement of sulfur dioxide emissions from stationary sources
				shall be made according to an applicable method specified in 40 CFR 60,
				appendix A, Method 6, 6A, 6B, or 6C, incorporated by reference in Section
				214.104(a),
				or by measurement procedures established pursuant to
				40 CFR 60.8
				(b), incorporated by reference in Section
				214.104(b),
				or by an installed certified continuous emissions monitoring system, or by an
				alternative monitoring method available under 40 CFR 75, incorporated by
				reference in Section
				214.104(e).
b) Sulfuric Acid Mist and Sulfur Trioxide
				Measurement. Measurement of sulfuric acid mist and sulfur trioxide shall be
				according to the barium-thorin titration method specified in 40 CFR 60,
				appendix A, Method 8, incorporated by reference in Section
				214.104(a),
				or a controlled condensate method approved in writing by the Agency.
c) Solid Fuel Averaging Measurement Daily
				Analysis Method. This subsection applies to sources at plants with total solid
				fuel-fired heat input capacity exceeding 439.5 MW (1500 mmBtu/hr). If daily
				fuel analysis is used to demonstrate compliance or non-compliance with Sections
				214.122,
				214.141,
				214.142(a)
									214.162,
				214.186 and
				214.421,
				the sulfur dioxide emission rate to be compared to the emission limit shall be
				considered to be the result of averaging daily samples taken over any
				consecutive two-month period provided no more than 5 percent of the sample
				values are greater than 20 percent above the sample average. If samples from a
				source cannot meet this statistical criterion, each individual daily sample
				analysis for such source shall be compared to the source's emission limit to
				determine compliance. The specific ASTM procedures, incorporated by reference
				in Section
				214.104(c),
				shall be used for solid fuel sampling, sulfur, and heating value
				determinations.
d) Weekly Analysis
				Method. This subsection applies to sources at plants with total solid
				fuel-fired heat input capacity exceeding 146.5 MW (500 mmBtu/hr) but not
				exceeding 439.5 MW (1500 mmBtu/hr). These plants shall demonstrate compliance
				or non-compliance with Sections 214.122, 214.141, 214.142(a), 214.162, 214.186
				and 214.421 by either an analysis of calendar weekly composites of daily fuel
				samples or by compliance with subsection (c), at the option of the plant. The
				specific ASTM procedures incorporated by reference in Section
				214.104(c),
				shall be used for sulfur and heating value determinations.
e) Monthly Analysis Method. This subsection
				applies to sources at plants with total fuel-fired heat input capacity
				exceeding 14.65 MW (50 mmBtu/hr) but not exceeding 146.5 MW (500 mmBtu/hr).
				These plants shall demonstrate compliance or non-compliance with Sections
				214.122, 214.141, 214.142(a), 214.162, 214.186 and 214.421 by either an
				analysis of calendar monthly composites of daily fuel samples or by compliance
				with subsection (c), at the option of the plant. ASTM procedures incorporated
				by reference in Section
				214.104(c),
				shall be used for sulfur and heating value determinations.
f) Small Source Alternative Method. This
				subsection applies to sources at plants with total solid fuel-fired heat input
				capacity not exceeding 14.65 MW (50 mmBtu/hr). Compliance or non-compliance
				with Sections 214.122, 214.141, 214.142(a), 214.162, 214.186 and 214.421 shall
				be demonstrated by a calendar month average sulfur dioxide emission
				rate.
g) Exemptions. Subsections
				(c) through (f) shall not apply to sources controlling sulfur dioxide emissions
				by flue gas desulfurization equipment or by sorbent injection.
h) Hydrogen Sulfide Measurement. For purposes
				of determining compliance with Section
				214.382(c),
				the concentration of hydrogen sulfide in petroleum refinery fuel gas shall be
				measured using the Tutwiler Procedure specified in
				40
				CFR 60.648, incorporated by reference in
				Section
				214.104(d).
