Acid Gas Flaring Incident definition

Acid Gas Flaring Incident means the continuous or intermittent combustion of Acid Gas and/or Sour Water Stripper Gas that results in the emission of sulfur dioxide equal to, or in excess of five-hundred (500) pounds in any twenty-four (24) hour period; provided, however, that if five hundred (500) pounds of more of sulfur dioxide have been emitted in a twenty-four (24) hour period and Flaring continues into subsequent, contiguous, non-overlapping twenty-four (24) hour period(s), each period of which results in emissions equal to, or in excess of five-hundred (500) pounds of sulfur dioxide, then only one AG Flaring Incident shall have occurred. Subsequent, contiguous, non-overlapping periods are measured from the initial commencement of Flaring within the AG Flaring Incident. “Acid Gas” means any gas that contains hydrogen sulfide and is generated at a refinery by the regeneration of amine solution.

Acid Gas Flaring Incident or “AG Flaring Incident” shall mean the continuous or intermittent combustion of Acid Gas and/or Sour Water Stripper Gas from one or more AG Flaring Devices at a Covered Refinery that results in the emission of sulfur dioxide equal to, or in excess of, five-hundred (500) pounds in any twenty-four (24) hour period. Where such continuous or intermittent combustion from one or more AG Flaring Devices continues into subsequent, contiguous, non-overlapping twenty-four (24) hour period(s), and sulfur dioxide equal to, or in excess of, five-hundred (500) pounds is emitted in each subsequent, contiguous, non-overlapping twenty-four (24) hour period(s), then only one AG Flaring Incident shall have occurred. Subsequent, contiguous, non-overlapping twenty-four (24) hour periods are measured from the initial commencement of AG Flaring within the AG Flaring Incident.

Examples of Acid Gas Flaring Incident in a sentence

• No later than 45 days following the end of an Acid Gas Flaring Incident, a Tail Gas Unit shutdown, bypass of a Tail Gas Unit, or other event resulting in a Tail Gas Incident, including scheduled and unscheduled Shutdowns of a Sulfur Recovery Plant, occurring after the Date of Entry, Shell shall conduct an investigation to identify the Root Cause(s) of the Flaring Incident and record the findings of the investigations in a report (“Root Cause Failure Analysis”).

• No later than sixty (60) days following the end of an Acid Gas Flaring Incident occurring after the Entry Date, Western shall conduct an investigation into the Root Cause or Causes of the incident and record the findings of the investigation in a report, which shall be submitted to EPA as part of a Semi-Annual Report as required by Paragraph 61 of this Decree.

• For purposes of this Consent Decree, the rate of SO2 emissions resulting from an Acid Gas Flaring Incident shall be expressed in terms of pounds per hour and shall be calculated by the following formula:ER = [FR][ConcH2S][0.169].The emission rate shall be rounded to one decimal point.

• For purposes of this Consent Decree, the quantity of SO2 emissions resulting from an Acid Gas Flaring Incident shall be calculated by the following formula:Tons of SO2 = [FR][TD][ConcH2S][8.44 x 10-5].

• To the extent the information is available, the report shall state the date and time that each Acid Gas Flaring Incident and each and Tail Gas Incident started and ended, each incident’s Root Cause or Causes, its estimated SO2 emissions and the calculations used to determine the quantity of emissions, and the corrective measures Western has implemented to address the Root Cause or Causes of the past incidents to minimize the number and duration of future Acid Gas Flaring Incidents.

Acid Gas Flaring Incident or “AG Flaring Incident” shall mean the continuous or intermittent combustion of Acid Gas and/or Sour Water Stripper Gas that results in the emission of sulfur dioxide equal to, or in excess of, five-hundred (500) pounds in any twenty-four (24) hour period; provided, however, that if five-hundred (500) pounds or more of sulfur dioxide have been emitted in a twenty-four (24) hour period and flaring continues into subsequent, contiguous, non-overlapping twenty-four (24) hour period(s), each period of which results in emissions equal to or in excess of five-hundred (500) pounds of sulfur dioxide, then only one AG Flaring Incident shall have occurred. Subsequent, contiguous, non-overlapping periods are measured from the initial commencement of flaring within the AG Flaring Incident. When AG Flaring occurs within a twenty-four hour period at more than one Flaring Device at a Covered Refinery, the quantities of sulfur dioxide attributable to AG Flaring emitted from each Flaring Device shall be added together for purposes of determining whether there is one AG Flaring Incident unless the root causes of the AG Flaring at the various Flaring Devices are not related to each other.

Acid Gas Flaring Incident or “AG Flaring Incident” shall mean the continuous or intermittent AG Flaring that results in the emission of sulfur dioxide equal to, or in excess of, 500 pounds in any 24-hour period.

Subsequent, contiguous, non-overlapping periods are measured from the initial commencement of flaring within the AG Flaring Incident. An AG Flaring Incident may entail the sulfur dioxide emissions from multiple sources provided that the flaring is associated with one common event.

Acid Gas Flaring Incident or “AG Flaring Incident” shall mean the continuous or intermittent combustion of Acid Gas and/or Sour Water Stripper Gas in an AG Flare that results in the emission of SO2 equal to, or in excess of, 500 pounds in any 24-hour period; provided, however, that if 500 pounds or more of sulfur dioxide has been emitted in a 24-hour period and Acid Gas Flaring continues into subsequent, contiguous, non-overlapping 24-hour period(s), each period of which results in emissions equal to, or in excess of, 500 pounds of SO2, then only one AG Flaring Incident shall have occurred. Subsequent, contiguous, non- overlapping periods are measured from the initial commencement of flaring within the AG Flaring Incident. If, at any time during the term of this Consent Decree, the Whiting Refinery has more than one AG Flare, and if AG Flaring occurs within a 24 hour period at more than one such AG Flare, the quantity of sulfur dioxide attributable to AG Flaring emitted from each such AG Flare shall be added together for purposes of determining whether there is one AG Flaring Incident, unless the root causes of the flaring at the various AG Flares are not related to each other.
