Current through Reg. 49, No. 28; July 12, 2024
(a)
					 Visible emissions. No person may cause, suffer, allow, or permit visible
					 emissions from any source, except as follows.
(1) Stationary vents. Visible emissions from
					 any vent shall not exceed the following opacities and must meet the following
					 requirements.
(A) Opacity shall not exceed
					 30% averaged over a six-minute period.
(B) Opacity shall not exceed 20% averaged
					 over a six-minute period for any source on which construction was begun after
					 January 31, 1972.
(C) Opacity shall
					 not exceed 15% averaged over a six-minute period for any source having a total
					 flow rate greater than or equal to 100,000 actual cubic feet per minute, unless
					 an optical instrument capable of measuring the opacity of emissions is
					 installed in the vent in accordance with subparagraph (D) of this paragraph.
					 Facilities utilizing such instruments shall meet opacity limits outlined in
					 subparagraph (A) or (B) of this paragraph as applicable. Records of all such
					 measurements shall be retained as provided for in §
													101.8 of this
					 title (relating to Sampling).
(D)
					 Any opacity monitoring system installed as provided for in subparagraph (C) of
					 this paragraph must satisfy the new source performance standards requirement
					 for opacity continuous emissions monitoring systems (CEMS) as contained in 40
					 Code of Federal Regulations (CFR) Part 60, Appendix B, Performance
					 Specification 1. In order to demonstrate compliance with Performance
					 Specification 1, the system shall undergo performance specification testing as
					 outlined in
					 40 CFR
					 60.13. The facility will maintain records of
					 all such testing for a period of not less than two years which shall be
					 available for inspection by federal, state, and local air pollution control
					 agencies. Compliance with this provision shall be accomplished within one year
					 of the effective date of this rule, except as specified in paragraph (2) of
					 this subsection.
(E) Visible
					 emissions during the cleaning of a firebox or the building of a new fire, soot
					 blowing, equipment changes, ash removal, and rapping of precipitators may
					 exceed the limits set forth in this section for a period aggregating not more
					 than six minutes in any 60 consecutive minutes, nor more than six hours in any
					 10-day period. This exemption shall not apply to the emissions mass rate
					 standard, as outlined in §
													111.151(a)
					 of this title (relating to Allowable Emissions Limits).
(F) Compliance with subparagraphs (A)-(C) of
					 this paragraph shall be determined by applying the following test methods, as
					 appropriate. The highest reading obtained shall determine compliance with the
					 appropriate visible emission limit:
(i) CEMS
					 as described in subparagraph (D) of this paragraph;
(ii) Test Method 9 (40 CFR
					 60, Appendix A);
(iii) Alternate Method 1 to Method 9, Light
					 Detection and Ranging (40
					 CFR 60, Appendix A); or
(iv) equivalent test method approved by the
					 executive director of the Texas Air Control Board (TACB) and United States
					 Environmental Protection Agency (EPA).
(G) Current certification of opacity readers
					 for determining opacities under
					 40 CFR
					 60, Appendix A, Method 9, shall be
					 accomplished by the successful completion of a TACB visible emissions
					 evaluator's course by opacity readers no more than 180 days before the opacity
					 reading.
