Excess NOx emissions definition

Excess NOx emissions means any tonnage of nitrogen oxides emitted by a NOx budget unit during a control period that exceeds the NOx budget emissions limitation for the unit.

Examples of Excess NOx emissions in a sentence

  • Excess NOx emissions shall be reported for all periods of Group G04 turbine operation, including startup, shutdown and malfunction.

  • Excess NOx emissions are defined as any 3-hour period during which the average emissions (arithmetic average of three contiguous one-hour periods) of NOx as measured by a CEMS exceed the applicable standard under '60.44.

  • Excess NOx emissions from these vehicles amounted to 6,000 tons during this period (600 tons per year or1.64 tons per day).

Related to Excess NOx emissions

  • Excess emissions - means an emission rate that exceeds any applicable emission limitation or standard allowed by any rule in Sections .0500, .0900, .1200, or .1400 of Subchapter 02D; or by a permit condition; or that exceeds an emission limit established in a permit issued under 15A NCAC 02Q .0700. (Note: Definitions of excess emissions under 02D .1110 and 02D .1111 shall apply where defined by rule.)

  • PM10 emissions means PM10 emitted to the ambient air as measured by an applicable reference method, or an equivalent or alternate method, specified in 40 CFR Part 51, Appendix M as of December 8, 1984, or by a test method specified in these regulations or any supplement thereto.

  • Allowable emissions means the emission rate of a stationary source calculated using both the maximum rated capacity of the source, unless the source is subject to federally enforceable limits which restrict the operating rate or hours of operation, and the most stringent of the following:

  • Actual emissions means the actual rate of emissions in tpy of any regulated pollutant (for fee calculation) emitted from a Part 71 source over the preceding calendar year. Actual emissions shall be calculated using each emissions unit’s actual operating hours, production rates, in-place control equipment, and types of materials processed, stored, or combusted during the preceding calendar year.

  • Secondary emissions means emissions which occur as a result of the construction or operation of a major stationary source or major modification, but do not come from the major stationary source or major modification itself. For the purposes of this chapter, “secondary emissions” must be specific, well-defined, and quantifiable, and must impact the same general areas as the stationary source modification which causes the secondary emissions. “Secondary emissions” includes emissions from any offsite support facility which would not be constructed or increase its emissions except as a result of the construction or operation of the major stationary source or major modification. “Secondary emissions” does not include any emissions which come directly from a mobile source, such as emissions from the tailpipe of a motor vehicle, from a train, or from a vessel.

  • Predictive emissions monitoring system or "PEMS" means all of the equipment necessary to monitor process and control device operational parameters (for example, control device secondary voltages and electric currents) and other information (for example, gas flow rate, O2 or CO2 concentrations), and calculate and record the mass emissions rate (for example, pounds per hour) on a continuous basis.

  • Greenhouse Gas Emissions means emissions in terms of tonnes of CO2 equivalent of carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), nitrogen trifluoride (NF3) and sulphur hexafluoride (SF6) determined pursuant to Regulation (EU) No 525/2013 and falling within the scope of this Regulation;

  • Baseline actual emissions means the rate of emissions, in tons per year, of a regulated NSR pollutant, as determined in accordance with paragraphs (i) through (iv) of this definition.

  • Particulate matter emissions (PM) means the mass of any particulate material from the vehicle exhaust quantified according to the dilution, sampling and measurement methods as specified in this UN GTR.

  • Visible emissions means any emissions, which are visually detectable without the aid of instruments, coming from RACM or asbestos-containing waste material, or from any asbestos milling, manufacturing, or fabricating operation. This does not include condensed, uncombined water vapor.

  • Fugitive emissions means those emissions which could not reasonably pass through a stack, chimney, vent, or other functionally equivalent opening.
