				less stringent than the control of emissions that is achieved in practice by
				the best controlled similar stationary source, as determined by the
				Administrator.
2. For existing

Nevada Administrative Code › Chapter 445B - Air Controls › AIR POLLUTION › General Provisions › Section 445B.22017 - Visible emissions: Maximum opacity; determination and monitoring of opacity

Current through June 11,
				2024
1. Except as
				otherwise provided in this section and NAC 445B.2202, no owner or operator may
				cause or permit the discharge into the atmosphere from any emission unit which
				is of an opacity equal to or greater than 20 percent. Opacity must be
				determined by one of the following methods:
(a) If opacity is determined by a visual
				measurement, it must be determined as set forth in Reference Method 9 in
				Appendix A of 40 C.F.R. Part 60.
(b) If a source uses a continuous monitoring
				system for the measurement of opacity, the data must be reduced to 6-minute
				averages as set forth in
				40 C.F.R. §
											60.13(h).

Current through June 11,
				2024
