j.	 The emergency notification requirements of CERCLA, 42 U.S.C. 

§ 9603(a), and of EPCRA, 42 U.S.C. § 11004(b). 

WHEREAS MPC does not admit any liability to the United States arising out of the 

transactions or occurrences alleged in the Complaint; 

WHEREAS, in March 2008, EPA began investigating MPC’s compliance with 

provisions of the CAA related to flares and shortly thereafter EPA and MPC commenced 

negotiations that included EPA’s identification of actions that MPC should take to reduce flare 

emissions, and MPC immediately started taking such actions at that time; 

WHEREAS, since 2008, MPC has provided a unique level of resources, expertise, and 

assistance to EPA to develop and advance the scientific knowledge and technology for 

measuring emissions of volatile organic compounds (“VOCs”) and hazardous air pollutants 

(“HAPs”) from industrial flares, including but not limited to: 

•	 Developing the protocol for and conducting the first-ever test of emissions from 

an operating, industrial flare using a then-new measurement technology called 

Passive Fourier Transfer Infrared (“PFTIR”) Spectroscopy 

•	 Implementing the PFTIR test at its Texas City refinery over a range of vent gas 

compositions and steam-to-vent-gas ratios to better define how to achieve 98% 

combustion efficiency (“CE”) from operating, industrial flares 

•	 Replicating the PFTIR test at another operating flare at the Detroit Refinery to 

improve the test method and accelerate technology development 

•	 Assuring rigorous and scientifically valid data collection 

•	 Preparing comprehensive and thorough PFTIR test reports for general distribution 

and use 

•	 Assisting in generating a consensus regarding the validity of PFTIR as a method 

for measuring emissions from flares 

2
 
•	 Evaluating the viability and reliability of an infrared smoke detector to maintain 

flare operation at the “incipient smoke point,” which is the visible manifestation 

of the point of highest CE; 

WHEREAS, since 2008, MPC has provided a unique level of cooperation to EPA to 

advance the understanding of the relationship between flare operating parameters and flare 

combustion efficiency, including but not limited to: 

•	 Evaluating the relationship between the net heating value (“NHV”) of the gas in 

the combustion zone of a flare and a flare’s CE 

•	 Isolating the effects of not just MPC’s typical vent gas compositions on a flares’ 

CE but also the effects of olefins such as propylene and butylene and inerts such 

as hydrogen and nitrogen 

•	 Leading the development of the theoretical and practical basis for dynamically 

calculating the NHV of the gas in a flare’s combustion zone and comparing it to 

the use of a static limit 

•	 Comparing actual Total Steam-to-Vent-Gas (“S/VG”) ratios to those predicted by 

the S/VG ratios in the American Petroleum Institute’s Recommended Practice 521 

to assist in the evaluation of S/VG as an appropriate metric of CE 

•	 Evaluating the effect of wind on CE, including developing white papers regarding 

Momentum Flux Ratio (“MFR”) and Steam Contribution Factor (“SCF”); 

WHEREAS MPC has represented that it incurred costs in excess of $2.4 million in 

undertaking the efforts described in the preceding two paragraphs; 

WHEREAS EPA regards MPC’s efforts as instrumental in accelerating the means of 

measuring VOC and HAP emissions from flares, reducing such emissions, and informing EPA’s 

enforcement efforts; 

WHEREAS MPC has agreed to install novel and unproven technology on a flare at its 

Robinson Refinery to determine whether such technology can reduce the minimum steam 

requirements of steam-assisted flares to ensure high CE at low vent gas flows; 

WHEREAS, since 2008, MPC has expended more than $45 million to reduce emissions 

from all of its flares (“Covered Flares”), including but not limited to installing, by the end of 

3
 

2011, the full suite of monitoring equipment required by Section V.A of this Consent Decree on 

seventeen of MPC’S twenty-two Covered Flares; 

WHEREAS MPC estimates that it will spend an additional $6.5 million (for a total of 

$51.5 million) to further reduce emissions from the Covered Flares and also will spend an 

additional, undetermined sum to comply with the flaring cap in Section V.B of this Consent 

Decree and with 40 C.F.R. Part 60, Subparts J and Ja; 

WHEREAS MPC estimates significant annual savings upon implementation of this 

consent decree through recovery of vent gas streams and reduced steam usage at its flares; 

WHEREAS, between 2008 and the end of 2011, EPA estimates that emissions from the 

Covered Flares have been reduced by approximately the following amounts (in “tons per year” 

or “TPY”): 

Pollutant 2008–2011 

Volatile Organic Compounds (“VOCs”) 4,720 TPY 

Carbon Dioxide Equivalents (“CO2e”) 119,500 TPY 

Hazardous Air Pollutants (“HAPs”) 110 TPY 

WHEREAS, between the beginning of 2012 and the full implementation of the controls 

required by this Consent Decree, MPC projects additional reductions, with total reductions 

approximately as follows: 

Pollutant Beginning of 2012 

through Implementation 

2008 through 

Implementation 

VOCs 

CO2e 

HAPs 

530 TPY 

2200 TPY 

30 TPY 

5,250 TPY 

121,700 TPY 

140 TPY 

WHEREAS EPA estimates that, between 2008 and the end of 2011, emissions of sulfur 

dioxide (“SO2”), hydrogen sulfide (“H2S”), and carbon monoxide (“CO”) from the Covered 

4
 

Flares also have been reduced and that further reductions very likely will take place between the 

beginning of 2012 and full implementation of the controls required by this Consent Decree; 

WHEREAS MPC estimates that the mitigation project required pursuant to Section VII 

(Mitigation Project) of this Decree will cost approximately $2.2 million; 

WHEREAS MPC has installed ambient air monitors at or near the fence lines of four of 

its Refineries in order to better understand the impact of its operations on neighboring 

communities, and MPC shares the monitoring data with neighboring communities; 

WHEREAS MPC has been in the vanguard of the refining industry in its willingness to 

propose and agree to install and maintain ambient air monitors, including having spent 

approximately $5.4 million on such monitors since 2008; 

WHEREAS, by entering into this Consent Decree, MPC has indicated that it is 

committed to continuing to proactively reduce emissions from its flares; 

WHEREAS this Consent Decree is intended to represent a comprehensive resolution of 

the claims alleged in the Complaint and the claims resolved through Section XIII (Effect of 

Settlement) and to ensure that when the compliance measures required by this Decree have been 

fully implemented, each Covered Flare will be operated and maintained to prevent a recurrence 

of the violations alleged in the Complaint and the violations resolved through Section XIII 

(Effect of Settlement); 

WHEREAS the United States anticipates that the specific and comprehensive compliance 

measures set forth in this Consent Decree, which are subject to a reasonable timetable for 

implementation, will result in the cessation of the violations alleged in the Complaint and the 

violations resolved through Section XIII (Effect of Settlement); 

5
 

WHEREAS MPC already has installed or has agreed to install through this Consent 

Decree Gas Chromatographs to speciate and measure the constituents of all Vent Gas directed to 

all Covered Flares and will utilize these Gas Chromatographs to calculate the NHV of the Vent 

Gas directed to the Covered Flares; 

WHEREAS the response time of a Gas Chromatograph requires the use of an averaging 

time for the NHV of the Vent Gas that is longer than the averaging time needed for a flare that 

utilizes a Vent Gas Net Heating Value Analyzer/Calculator; 

WHEREAS, MPC already has submitted the report required in Paragraph 16 of this 

Consent Decree for the Covered Flares at its Catlettsburg Refinery, all of the Covered Flares at 

its Detroit Refinery except the Coker Flare (which is not yet in operation), and Covered Flares 

84-F1, 84-F5, and 84-F6 at its Robinson Refinery; 

WHEREAS, the United States and MPC (the “Parties”) recognize, and this Court by 

entering this Consent Decree finds, that this Consent Decree has been negotiated by the Parties in 

good faith and will avoid litigation between the Parties, and that this Consent Decree is fair, 

reasonable, and in the public interest; 

NOW, THEREFORE, before the taking of any testimony, without the adjudication or 

admission of any issue of fact or law except as provided in Section I, and with the consent of the 

Parties, IT IS HEREBY ADJUDGED, ORDERED, AND DECREED as follows:

States and upon MPC and any successors, assigns, and other entities or persons otherwise bound 

by law. 

5. MPC shall give written notice of, and shall provide a copy of, the Consent Decree 

to any successors in interest at least sixty (60) days prior to the transfer of ownership or 

operation of any portion of the Covered Refineries. MPC shall notify the United States in 

accordance with the notice provisions in Section XV (Notice) of any successor in interest at least 

thirty days prior to any such transfer. 

6. If MPC intends to request that the United States agree to a transferee’s 

assumption of any obligations of the Consent Decree, MPC shall condition any transfer, in whole 

7
 

or in part, of ownership of, operation of, or other interest (exclusive of any non-controlling, 

non-operational shareholder interest) in the Covered Refinery upon the transferee’s written 

agreement to execute a modification to the Consent Decree that shall make the terms and 

conditions of the Consent Decree applicable to the transferee. 

7. As soon as possible prior to the transfer: (i) MPC shall notify the United States of 

the proposed transfer and of the specific Consent Decree provisions that MPC proposes the 

transferee assume; (ii) MPC shall certify that the transferee is contractually bound to assume the 

obligations and liabilities of this Consent Decree; and (iii) the transferee shall submit to the 

United States a certification that the transferee has the financial and technical ability to assume 

the obligations and liabilities of this Consent Decree and a certification that the transferee is 

contractually bound to assume the obligations and liabilities of this Consent Decree. 

8. After the submission to the United States of the notice and certification required 

by the previous Paragraph, either: (i) the United States, shall notify MPC that the United States 

does not agree to modify the Consent Decree to make the transferee responsible for complying 

with the terms and conditions of the Consent Decree; or (ii) the United States, MPC, and the 

transferee shall file with the Court a joint motion requesting the Court approve a modification 

substituting the transferee for MPC as the Defendant responsible for complying with the terms 

and conditions of the Consent Decree. 

9. If MPC does not secure the agreement of the United States to a joint motion 

within a reasonable period of time, then MPC and the transferee may file, without the agreement 

of the United States, a motion requesting the Court to approve a modification substituting the 

transferee for MPC as the Defendant responsible for complying with some or all of the terms and 

conditions of the Consent Decree. The United States may file an opposition to the motion. The 

8
 

motion to modify shall be granted unless MPC and the transferee: (i) fail to show that the 

transferee has the financial and technical ability to assume the obligations and liabilities of the 

Consent Decree; (ii) fail to show that the modification language effectively transfers the 

obligations and liabilities to the transferee; or (iii) the Court finds other good cause for denying 

the motion. 

10. Except as provided in Paragraphs 5–9 and Section X (Force Majeure), MPC shall 

be responsible for ensuring that performance of the work contemplated under this Consent 

Decree is undertaken in accordance with the deadlines and requirements contained in this 

Consent Decree and any attachments hereto. MPC shall provide a copy of all applicable portions 

of this Consent Decree to all officers and employees whose duties might reasonably include

instrumentation and monitoring systems identified in Paragraphs 18–20 and 22–24 shall be able 

to produce and record data measurements and calculations for each parameter at the following 

time intervals. 

Instrumentation and Monitoring System Recording and Averaging Times 

Vent Gas Flow; 

Vent Gas Average Molecular Weight; 

Total Steam Flow; 

Pilot Gas Flow (if installed) 

Measure continuously and record 5 

minute block averages 

Gas Chromatograph Measure no less than once every 15 

minutes and record that value 

Wind Speed Measure continuously and record 5 

minute block averages 

Video Camera, if required Record at a rate of no less than 4 

frames per minute 

Nothing in this Paragraph is intended to prohibit MPC from setting up process control logic that 

uses different averaging times from those in this table provided that the recording and averaging 

times in this table are available and used for determining compliance with this Consent Decree. 

28. Instrumentation and Monitoring Systems: Operation and Maintenance. MPC 

shall operate each of the instruments and monitoring systems required in Paragraphs 18–20, 22– 

23, and, if applicable, 24, on a continuous basis except for the following periods: 

a. Malfunction of an instrument; 

b. Maintenance following instrument Malfunction; 

29
 
c. Scheduled maintenance of an instrument in accordance with the 

manufacturer’s recommended schedule; 

d. Quality Assurance/Quality Control activities; and/or 

e. When the Covered Flare that the instrument or monitoring system is 

associated with is not in service. 

In no event, however, shall the excepted activities in Subparagraph 28.a–28.d for any instrument 

exceed 110 hours in any calendar quarter. The calculation of instrument downtime shall be made 

in accordance with 40 C.F.R. § 60.13(h)(2) and Paragraph VI of Appendix 1.10. If the excepted 

activities in Subparagraphs 28.a–28.d for any instrument exceed 110 hours in any calendar 

quarter, EPA shall be entitled to seek stipulated penalties as set forth in Subparagraph 77.e of this 

Consent Decree and MPC shall be entitled to assert that the period of instrumentation and 

monitoring system downtime was justified under the circumstances. Nothing in this Paragraph is 

intended to prevent MPC from claiming a force majeure defense to any period of instrumentation 

and/or monitoring system downtime. Nothing in this Paragraph supersedes or replaces the 

monitoring requirements, including operation, maintenance, and quality assurance/quality 

control requirements of 40 C.F.R. Part 60, Subparts J and Ja (including monitoring requirements 

in Subpart Ja that may be stayed as of the Date of Lodging of this Consent Decree but may 

become effective after the Date of Lodging) at such time as those requirements become 

applicable pursuant to Paragraphs 58 and 59. All such requirements shall apply in accordance 

with the terms set forth in Subparts J and Ja. 

29. Taking Certain Flares Out of Service. By no later than December 31, 2012, MPC 

shall take the following flares out of service by physically removing piping in the Flare header or 

physically isolating the piping with a welded blind so as to eliminate direct piping to these flares: 

the Canton South Flare designated as 04-14-B-002 and the Catlettsburg Pitch Flare designated as 

30
 

1-14-FS-1. To the extent that any operating permit of MPC’s allows for the operation of these 

flares, MPC shall submit a request to the applicable state agency by no later than 6 months after 

taking these flares out of service, to amend the operating permit to reflect the permanent 

disconnection of these flares. 

B.	 Waste Gas Minimization 

30. Initial Waste Gas Minimization Plan (“Initial WGMP”). By no later than the 

dates set forth in Column D of Appendix 2.1, MPC shall submit to EPA an Initial Waste Gas 

Minimization Plan for each Covered Flare that discusses and evaluates flaring Prevention 

Measures both Refinery-wide and on a Flare-specific basis. The Initial WGMP shall include but 

not be limited to: 

a. Updates. MPC shall submit updates, if and as necessary, to the 

information, diagrams, and drawings provided in the Flare Data and Monitoring Systems and 

Protocol Report required under Paragraph 16. 

b. Waste Gas Characterization and Mapping. MPC shall undertake to 

characterize the Waste Gas being disposed of at each Covered Flare and determine its source as 

follows: 

i.	 Volumetric (in scfm) and mass (in pounds) flow rate. MPC shall 

identify the volumetric flow of Waste Gas, in scfm on a 30-day 

rolling average, and the mass flow rate, in pounds per hour on a 

30-day rolling average, vented to each Covered Flare at the 

Covered Refinery for the one-year period of time between the date 

in Column C of Appendix 2.1 that applies to the Covered Flare and 

31 days before the submission of the Initial WGMP. To the extent 

that, for any particular Covered Flare, MPC has instrumentation 

capable of measuring the volumetric and mass flow rate of 

hydrogen, nitrogen, oxygen, carbon monoxide, carbon dioxide, 

and/or steam in the Waste Gas, MPC may break down the 

volumetric and mass flow as between: (i) All Waste Gas flows 

excluding hydrogen, nitrogen, oxygen, carbon monoxide, carbon 

dioxide, and/or water (steam); and (ii) hydrogen, nitrogen, oxygen, 

31
 
carbon monoxide, carbon dioxide, and/or water (steam) flows in 

the Waste Gas. MPC may use either an engineering evaluation or 

measurements from monitoring or a combination to determine flow 

rate. In determining flow rate, flows during all periods (including 

but not limited to normal operations and periods of Startup, 

Shutdown, Malfunction, process upsets, relief valve leakages, 

power losses due to an interruptible power service agreement, and 

emergencies arising from events within the boundaries of the 

Covered Refinery), except those described in the next sentence, 

shall be included. Flows that could not be prevented through 

reasonable planning and are in anticipation of or caused by a 

natural disaster, act of war or terrorism, or External Power Loss are 

the only flows that shall be excluded from the calculation of flow 

rate. MPC shall specifically describe the date, time, and nature of 

the event that results in the exclusion of any flows from the 

calculation. 

ii.	 Baseload Waste Gas Flow Rates. MPC shall utilize flow rate data 

for the one-year period of time between the date in Column C of 

Appendix 2.1 that applies to the Covered Flare and 31 days before 

the submission of the Initial WGMP to determine the Baseload 

Waste Gas Flow Rate, in scfd, to each Covered Flare. The 

Baseload Waste Gas Flow Rate shall not include flows during 

periods of Startup, Shutdown, and Malfunction. 

iii.	 Identification of Constituent Gases. MPC shall use best efforts to 

identify the constituent gases within each Covered Flare’s Waste 

Gas and the percentage contribution of each such constituent 

during baseload conditions. MPC may use either an engineering 

evaluation or measurements from monitoring or a combination to 

determine Waste Gas constituents. 

iv.	 Waste Gas Mapping. Using instrumentation, isotopic tracing, 

and/or engineering calculations, MPC shall identify and estimate 

the flow from each process unit header (sometimes referred to as a 

“subheader”) to the main header(s) servicing the Covered Flare. 

Using that information and all other available information, MPC 

shall complete an identification of each Waste Gas tie-in to the 

main header(s) and process unit header(s), as applicable, consistent 

with Appendix 1.11. Temporary connections to the main header(s) 

of a Covered Flare and/or process unit header(s) are not required to 

be included in the mapping. 

c. Reductions previously realized. MPC shall describe the equipment, 

processes and procedures installed or implemented since January 2009 to reduce flaring. The 

32
 

description shall specify the date of installation or implementation and the amount of reductions 

realized. 

d. Planned reductions . MPC shall describe the equipment, processes, or 

procedures that MPC plans to install or implement to eliminate or reduce flaring. The 

description shall specify a schedule for expeditious installation and commencement of operation 

and a projection of the amount of reductions to be realized. Subsequent to the submission of the 

WGMP, MPC may revise the installation and operation dates provided that MPC does so in 

writing to EPA within a reasonable time of determining that such a revision(s) is(are) necessary 

and provides a reasonable explanation for the revised date(s). In formulating this plan, MPC 

specifically shall review and evaluate the results of the Waste Gas Mapping required by 

Subparagraph 30.b.iv. 

e. Taking a Covered Flare Out of Service . MPC shall identify any Covered 

Flare that it intends to take out of service, including the date for completion of the 

decommissioning. Taking a Covered Flare “out of service” means physically removing piping in 

the Flare header or physically isolating the piping with a welded blind so as to eliminate direct 

piping to the Covered Flare. 

f. Prevention Measures . MPC shall describe and evaluate all Prevention 

Measures, including a schedule for the expeditious implementation and commencement of 

operation of all Prevention Measures, to address the following: 

i.	 Flaring that has occurred or may reasonably be expected to occur 

during planned maintenance activities, including Startup and 

Shutdown. The evaluation shall include a review of flaring that 

has occurred during these activities since January 2009 and shall 

consider the feasibility of performing these activities without 

flaring. 

33
 
ii.	 Flaring that may reasonably be expected to occur due to issues of 

gas quantity and quality. The evaluation shall include a general 

audit of the existing flare gas recovery capacity of each Covered 

Flare, the storage capacity available for excess Waste Gases, and 

the scrubbing capacity available for Waste Gases including any 

limitations associated with scrubbing Waste Gases for use as fuel. 

iii.	 Flaring caused by the recurrent failure of air pollution control 

equipment, process equipment, or a process to operate in a normal 

or usual manner. The evaluation shall consider the adequacy of 

existing maintenance schedules and protocols for such equipment. 

A failure is “recurrent” if it occurs more than twice during any five 

year period as a result of the same cause. 

31. First Updated Waste Gas Minimization Plan. By no later than the dates set forth 

in Column E of Appendix 2.1, MPC shall submit to EPA a First Updated WGMP which shall 

update for the 12-month period after the period covered by the Initial Waste Gas Minimization 

Plan, if and as necessary, the information required in Subparagraphs 30.a–30.f and shall also 

include the following: 

a.	 Updated Waste Gas Mapping. MPC shall update the Waste Gas mapping 

as more information becomes available. MPC shall use this updated 

mapping to plan reductions; 

b.	 Reductions Based on Root Cause Analysis. MPC shall review all of the 

Root Cause Analysis reports submitted under Paragraph 35 to determine if 

reductions in addition to the reductions achieved through any required 

corrective action under Paragraph 37 can be realized; and 

c.	 Revised Schedule. To the extent that MPC proposes to extend any 

schedule set forth in the Initial WGMP, MPC may do so only with good 

cause. 

32. Subsequent Updates to Waste Gas Minimization Plan. In the first semi-annual 

report required under Section VIII of this Decree (Reporting Requirements) that is due in July of 

the year that is one year after the submission of the First Updated WGMP, MPC shall submit a 

Second Updated WGMP. On an annual basis thereafter until termination of the Decree, MPC 

shall submit an updated WGMP as part of the July semi-annual report. Each update shall update, 

34
 

if and as necessary, the information required in Subparagraphs 30.a–30.f, 31.a, and 31.b. To the 

extent that MPC proposes to extend any schedule set forth in a previous WGMP, MPC may do 

so only with good cause. 

33. Waste Gas Minimization Plan: Implementation. By no later than the dates 

specified in a WGMP, MPC shall implement the actions described therein. If (i) no 

implementation date and/or (ii) no completion date for actions that do not require ongoing 

implementation (such as the installation of a piece of a equipment) is (are) set forth in the 

WGMP, the implementation and/or completion date shall be deemed the date of the submission 

of the WGMP. 

34. Enforceability of WGMPs. The terms of each WGMP (including Initial, First 

Updated, and Subsequent Updated WGMPs) submitted under this Consent Decree are 

specifically enforceable. 

35.	 Root Cause Analysis for Reportable Flaring Incident. 

a. Internal Reporting and Recordkeeping . Except as provided in 

Paragraphs 36 and 38.a, commencing on the dates set forth in the definition of “Reportable 

Flaring Incident” in Section III of this Decree (Definitions), by no later than forty-five days 

following the end of a Reportable Flaring Incident, MPC shall conduct an investigation into the 

Root Cause(s) of the Incident and prepare and keep as a record an internal report that shall 

include, at a minimum, the following: 

i.	 The date and time that the Reportable Flaring Incident started and 

ended; 

ii.	 The volume of Waste Gas flared and an estimate of the quantity of 

VOCs and SO2 that was emitted and the calculations that were 

used to determine that quantity; 

iii..	 The steps, if any, that MPC took to limit the duration of the 

35
 
Reportable Flaring Incident and quantity of VOC and/or SO2 

emissions associated therewith; 

iv.	 A detailed analysis that sets forth the root cause and all 

contributing causes of the Reportable Flaring Incident, to the 

extent determinable; 

v.	 An analysis of the measures, if any, that are available to reduce the 

likelihood of a recurrence of a Reportable Flaring Incident 

resulting from the same root cause or contributing causes in the 

future. The analysis shall discuss the alternatives, if any, that are 

available, the probable effectiveness and the cost of the 

alternatives, if an alternative is eliminated based on cost. Possible 

design and operation and maintenance changes shall be evaluated. 

If MPC concludes that corrective action(s) is (are) required under 

Paragraph 37, the report shall include a description of the action(s) 

and, if not already completed, a schedule for its (their) 

implementation, including proposed commencement and 

completion dates. If MPC concludes that corrective action is not 

required under Paragraph 37, the report shall explain the basis for 

that conclusion; and 

vi.	 To the extent that investigations of the causes and/or possible 

corrective actions still are underway 45 days after the Reportable 

Flaring Incident, a statement of the anticipated date by which a 

follow-up report fully conforming to the requirements of this 

Paragraph shall be completed. 

b. Submitting Summary of Internal Flaring Incident Reports. In each 

semi-annual report due under Section VIII of this Decree (Reporting Requirements), MPC shall 

include a summary of the following items for each Reportable Flaring Incident that occurred 

during the six-month period that the semi-annual report covers: 

i.	 Date; 

ii.	 Duration; 

iii.	 Amount of SO2 and VOC released; 

iv.	 Root Cause(s); 

v.	 Corrective Action(s) completed; 

36
 
vi.	 Corrective Action(s) still outstanding; and 

vii.	 An analysis of any trends identified by MPC in terms of the 

number of Incidents, the Root Causes, or the types of Corrective 

Action. 

36. In lieu of preparing a new report under Paragraph 35 and analyzing and 

implementing corrective action under Paragraph 37 for a Reportable Flaring Incident that has as 

its root cause the same root cause as a previously reported Reportable Flaring Incident, MPC 

may cross-reference and utilize the prior report and analysis when preparing the report required 

by Paragraph 35. 

37. Corrective Action Implementation. In response to any Reportable Flaring 

Incident occurring after the Date of Lodging, MPC shall take, as expeditiously as practicable, 

such interim and/or long-term corrective actions, if any, as are consistent with good engineering 

practice to minimize the likelihood of a recurrence of the root cause and all contributing causes 

of that Reportable Flaring Incident. 

38.	 Overlapping Requirements. 

a. Root Cause Analysis and Corrective Action Requirements under MPC’s 

PRI Consent Decree . To the extent that a Reportable Flaring Incident that is triggered solely by 

the SO2 threshold in the definition of “Reportable Flaring Incident” also constitutes an Acid Gas 

or Hydrocarbon Flaring Incident under MPC’s PRI Consent Decree, MPC shall follow the 

provisions of MPC’s PRI Consent Decree, and not the provisions of this Decree, for addressing 

the incident, for as long as MPC’s PRI Consent Decree is in effect. 

b. Root Cause Analysis and Corrective Action Provisions of NSPS 

Subpart Ja. To the extent that currently stayed provisions of Subpart Ja of the New Source 

Performance Standards (“NSPS”) that affect the applicability of requirements to undertake root 

37
 

cause analyses and corrective actions, 73 Fed. Reg. 78,522, 78,539 (Dec. 22, 2008), 40 C.F.R. 

§§ 60.103a(b),(c), are finalized after the Date of Lodging of this Consent Decree, and to the 

extent that compliance with those provisions overlaps with compliance with Paragraphs 35 and 

37, MPC shall comply with the requirements of the finalized Subpart Ja and also comply with 

each requirement in Paragraphs 35 and 37 that is not inconsistent with the requirements of a 

finalized Subpart Ja. 

c. Flare Management Plan Provisions of NSPS Subpart Ja . To the extent that 

currently stayed provisions of Subpart Ja of the NSPS that affect the applicability of 

requirements to develop and implement flare management plans, 73 Fed. Reg. 78,522, 78,538-39 

(Dec. 22, 2008), 40 C.F.R. § 60.103a(a), are finalized after the Date of Lodging of this Consent 

Decree, and to the extent that compliance with those provisions overlaps with compliance with 

Paragraphs 30–33, MPC shall comply with the requirements of the finalized Subpart Ja and also 

comply with each requirement in Paragraphs 30–33 that is not inconsistent with the requirements 

of a finalized Subpart Ja. 

39. Limitations on Flaring. By no later than the dates set forth in Column I of 

Appendix 2.1, the following limitations on flaring shall be in effect: 

38

Each exceedance of the 30-day rolling average limit or each exceedance of the 365-day rolling 

average limit shall constitute one day of violation. An exceedance of either or both of the limits 

shall not prohibit ongoing refinery operations. 

40. Limitation on Flaring: Meaning of “Waste Gas” in Paragraph 39 . For purposes 

of the meaning of “Waste Gas” in Paragraph 39, the following shall apply: 

a.	 To the extent that MPC has instrumentation capable of measuring the 

volumetric flow rate of hydrogen, nitrogen, oxygen, carbon monoxide, 

carbon dioxide, and/or water (steam) in the Waste Gas, the contribution of 

all measured flows of any of these elements/compounds may be excluded 

from the Waste Gas flow rate calculation. 

b.	 Waste Gas flows during all periods (including but not limited to normal 

operations and periods of Startup, Shutdown, Malfunction, process upsets, 

relief valve leakages, power losses due to an interruptible power service 

agreement, and emergencies arising from events within the boundaries of 

the Covered Refinery), except those described in the next sentence, shall 

be included. Flows that could not be prevented through reasonable 

planning and are in anticipation of or caused by a natural disaster, act of 

39
 
war or terrorism, or External Power Loss are the only flows that may be 

excluded from the calculation of flow rate. 

c.	 Except for hydrogen, nitrogen, oxygen, carbon monoxide, carbon dioxide, 

and/or water (steam) contributions to the flow rate that are excluded by 

virtue of instrumentation measuring these flows, for any flow that MPC 

does not include in a computation, MPC shall submit in the semi-annual 

report due under Paragraph 69, the following: a description of the event 

that resulted in the exclusion; the date(s) and duration(s) of the flows 

caused by the event; the estimated VOC and SO2 emissions during the 

event; whether flows from the event still are anticipated to persist after the 

period covered by the report, and if so, for how long; and the measures 

taken or to be taken to prevent or minimize the flows including, for future 

anticipated flow, the schedule by which those measures will be 

implemented. 

C.	 Flare Combustion Efficiency 

41. Emission Standards and Work Practices Applicable to each Covered Flare upon 

the Date of Lodging. As set forth in Column F of Appendix 2.1, beginning no later than the Date 

of Lodging for all Covered Flares except for the Detroit Coker Flare (which is not yet in 

operation), and by no later than June 30, 2013, for the Detroit Coker Flare, MPC shall comply 

with the following requirements at each Covered Flare: 

a. Operation during Emissions Venting. MPC shall operate each Covered 

Flare at all times when emissions may be vented to it. 

b. No Visible Emissions. Except for periods of Startup, Shutdown, and/or 

Malfunction, MPC shall operate each Covered Flare with no Visible Emissions. Method 22 in 

40 C.F.R. Part 60, Appendix A, shall be used to determine compliance with this standard. 

However, for purposes of this Consent Decree, Visible Emissions may be determined by either a 

person certified pursuant to Method 22 or a video camera. 

c. Flame Presence. Except for periods of Malfunction of the Flare, MPC 

shall operate each Covered Flare with a flame present at all times. MPC shall monitor the 

40
 

presence of the pilot flame using a thermocouple or any other equivalent device to detect the 

presence of the pilot flame. 

d. Monitoring According to Applicable Provisions . MPC shall comply with 

all applicable Subparts of 40 C.F.R. Parts 60, 61, or 63 that state how a particular Covered Flare 

must be monitored. 

e. Good Air Pollution Control Practices. At all times, including during 

periods of Startup, Shutdown, and/or Malfunction, MPC shall implement good air pollution 

control practices to minimize emissions from each Covered Flare; provided however, that MPC 

shall not be in violation of this requirement for any practice that this Consent Decree requires 

MPC to implement after the Date of Lodging for the period between the Date of Lodging and the 

implementation date or compliance date (whichever is applicable) for the particular practice. 

42. Exit Velocity. Beginning no later than the dates set forth in Column C of 

Appendix 2.1, except for the Garyville Ground Flares, and except for periods of Startup, 

Shutdown, and/or Malfunction, MPC shall operate each Covered Flare with an Exit Velocity less 

than 18.3 m/sec (60 ft/sec) on a one-hour block average; provided however, that: 

a.	 Except for the Garyville Ground Flares, for any Covered Flare that 

combusts Vent Gas with a Net Heating Value of greater than 1000 

BTU/scf, MPC may operate the Covered Flare with an Exit Velocity equal 

to or greater than 18.3 m/sec (60 ft/sec) but less than 122 m/sec (400 

ft/sec) on a one-hour block average; 

b.	 Except for the Garyville Ground Flares, for any Covered Flare that has a 

maximum permitted Exit Velocity (Vmax), MPC may operate the Covered 

Flare with an Exit Velocity less than Vmax provided that it also operates 

this Flare with an Exit Velocity of less than 122 m/sec (400 ft/sec) on a 

one-hour block average; and 

c.	 Except for periods of Startup, Shutdown, and/or Malfunction, MPC shall 

operate the Garyville Ground Flares with an Exit Velocity that shall be 

determined through the testing required pursuant to Paragraph 52. 

41
 

Vmax shall be calculated in accordance with 40 C.F.R. § 60.18(f)(5). The Unobstructed Cross 

Sectional Area of the Flare Tip shall be calculated consistent with Appendix 1.6. 

43. Work Practice Standards for each Covered Flare. By no later than the dates set 

forth in Column G of Appendix 2.1, utilizing the instrumentation and controls required to be 

installed pursuant to Paragraphs 18–23, MPC shall install and operate on each Covered Flare an 

Automatic Control System that shall: 

a.	 Automate the control of the Supplemental Gas flow rate to the respective 

Flare; and 

b.	 Automate the control of the Total Steam Volumetric Flow Rate to the 

respective Flare. 

44. Exception to Part of the Work Practice Standards in Subparagraph 43.b . MPC 

manually may override the operation of the Automatic Control System required in 

Subparagraph 43.b (for control of Total Steam Volumetric Flow Rate) if the exception in 

Paragraph 50 applies, and/or during Startup, Shutdown, or Malfunction of a process unit that 

feeds the Covered Flare, and/or to achieve the following: 

a.	 Stop Smoke Emissions that are occurring; 

b.	 Meet the Net Heating Value requirements of Paragraph 46; 

c.	 Prevent extinguishing the Flare; 

d.	 Protect personnel safety; and/or 

e.	 Stop Discontinuous Wake Dominated Flow 

45. Operation According to Design. By no later than the dates set forth in Column H 

of Appendix 2.1, MPC shall operate and maintain each Covered Flare in accordance with its 

design, except if, and only to the extent that, operation and maintenance of the Covered Flare in 

42
 

conformance with its design conflicts with compliance with one or more of the requirements of 

this Consent Decree. 

46.	 Net Heating Value Standards for each Covered Flare. 

a. Net Heating Value of Vent Gas (NHVvg). Beginning on the Date of 

Lodging and continuing until the earlier of: (i) termination of this Consent Decree; or (ii) the 

requirements in 40 C.F.R. §§ 60.18(c)(3)(ii) and 63.11(b)(6)(ii) related to the NHVvg are 

modified, MPC shall operate each Covered Flare with an NHVvg of greater than or equal to 300 

BTU/scf, except as provided in Paragraph 50. 

b.	 Net Heating Value of Combustion Zone Gas (NHVcz). 

i.	 By no later than the dates set forth in Column H of Appendix 2.1, 

and except as provided in Paragraph 50, MPC shall calculate an 

NHVcz-limit at each Covered Flare no less than every fifteen minutes. 

Except as provided in Paragraph 50, MPC shall operate each 

Covered Flare so as to ensure that the Covered Flare’s NHVcz, on a 

three-hour rolling average basis, rolled every fifteen minutes, is 

greater than or equal to its NHVcz-limit on a three-hour rolling 

average basis, rolled every fifteen minutes. MPC shall utilize the 

equations and directives set forth in Appendix 1.3, except as 

provided in Subparagraph 46.b.ii, to meet the requirements of this 

Subparagraph 46.b.i. 

ii.	 Interim Combustion Efficiency (CE) Multiplier s. Between the 

dates set forth in Column H of Appendix 2.1 and June 30, 2017, 

MPC may use the following Table of CE Multipliers instead of the 

CE Multipliers in Table 2 of Appendix 1.3 provided that MPC 

complies with the conditions in Subparagraph 46.b.iii: 

Minimum Steam

Vent Gas as follows: 

Condition X: 3≤H2%≤8 and Propylene%≥H2% (all percents are volume or mole percents) 

Condition Y: Any condition not meeting the requirements for Condition X. 

43 
iii.	 Conditions for the Use of Interim CE Multipliers. In order to use 

the Interim CE Multipliers in Subparagraph 46.b.ii, MPC must 

comply with each of the following: 

(a)	 By no later than December 31, 2013, MPC shall install a 

Minimum Steam Reduction System (“MSRS”) on Covered 

Flare 84-F1 at the Robinson Refinery (“Robinson 84-F1”). 

(b)	 Between January 1, 2014, and June 30, 2014, in order to 

evaluate emissions, Combustion Efficiency, and the 

effectiveness of MSRS, MPC shall conduct Passive FTIR 

testing on Robinson 84-F1. By no later than 45 days prior 

to the test, MPC shall submit an Emissions and 

Combustion Efficiency Test Protocol in accordance with 

the general requirements in Appendix 2.3. The test 

protocol also shall describe how the testing will evaluate 

the effectiveness of the MSRS. MPC shall complete the 

testing within 30 days of commencing the test. 

(c)	 By no later than June 30, 2014, MPC shall submit a report 

that complies with the requirements of Paragraph 53. The 

report also shall include an evaluation of the effectiveness 

of the MSRS. 

(d)	 By no later than June 30, 2017, MPC shall submit a report 

to EPA that evaluates the feasibility and effectiveness of 

the use of MSRS at each Covered Flare that has a minimum 

steam requirement of greater than 1000 lb/hr. In that 

report, MPC shall identify each Covered Flare that it shall 

equip with MSRS, together with a schedule for installation 

as soon as practicable. 

iv.	 Final CE Multipliers. 

(a)	 For those equipped or to be equipped with MSRS. 

Between the dates set forth in Column H of Appendix 2.1 

and the termination of the Decree, MPC shall be entitled to 

use, in the calculation of a Covered Flare’s NHVcz-limit, the 

Interim CE Multipliers set forth in Subparagraph 46.b.ii, 

instead of those in Table 2 of Appendix 1.3, for the 

Robinson 84-F1 and for each Covered Flare identified in 

Subparagraph 46.b.iii.(d), provided that, with respect to 

those identified in Subparagraph 46.b.iii.(d), MPC 

completes the installation of an MSRS in accordance with 

the proposed schedule. 

44
 
(b)	 For those not scheduled to be equipped with MSRS. 

Between June 30, 2017, and the termination of this Decree, 

MPC shall be required to use, in the calculation of a 

Covered Flare’s NHVcz-limit, the CE Multipliers set forth in 

Table 2 of Appendix 1.3 for all Covered Flares that are not 

identified in the report due under Subparagraph 46.b.iii.(d) 

as committed to be equipped with MSRS. 

47. S/VGmass and S/VGvol Standards (Total-Steam-Volumetric-Flow-Rate-toVent-Gas-Volumetric-Flow-Rate Ratio Standards) 

a. Interim Period. Beginning on the Date of Lodging and continuing until 

the dates set forth in Column H of Appendix 2.1, and except as provided in Subparagraph 47.d 

and Paragraph 50, MPC shall use best efforts to operate each Covered Flare so as to minimize 

that Flare’s S/VGmass and/or S/VGvol. 

b. After Interim Period. By no later than the dates set forth in Column H of 

Appendix 2.1, and except as provided in Subparagraph 47.d and Paragraph 50, MPC shall 

operate each Covered Flare, except the Garyville Ground Flares, at less than or equal to either: 

(i) an S/VGmass of 3.0 on a one-hour rolling average, rolled every five minutes; or (ii) an S/VGvol 

of 2.7 on a one-hour rolling average, rolled every five minutes. For each Covered Flare, MPC 

shall record both the S/VGmass and the S/VGvol. MPC shall operate the Garyville Ground Flares 

with an S/VGmass and/or an S/VGvol that shall be determined through the testing required pursuant 

to Paragraph 52. 

c. Adjustment at the Texas City Main Flare Based on Steam Contribution 

Factor. 

i.	 Texas City Main Flare. For purposes of compliance with 

Subparagraph 47.b at the Texas City Main Flare, MPC may utilize 

the Total Steam Mass Flow Rate as Corrected by the Steam 

Contribution Factor for the Texas City Main Flare instead of the 

Total Steam Mass Flow Rate and the Total Steam Volumetric Flow 

Rate as Corrected by the Steam Contribution Factor for the Texas 

45
 
City Main Flare instead of the Total Steam Volumetric Flow Rate. 

To calculate the Total Steam Mass and Volumetric Flow Rates as 

Corrected by the Steam Contribution Factor for the Texas City 

Main Flare, MPC shall utilize Equation 1 in Appendix 2.2 to first 

calculate the Non-Mixing Total Steam for the Texas City Main 

Flare. Thereafter, MPC shall use Equations 2–4B of Appendix 2.2 

to calculate the Total Steam Mass and Volumetric Flow Rates as 

Corrected by the Steam Contribution Factor for the Texas City 

Main Flare. 

ii.	 Other Covered Flares. At any time after the Date of Lodging, for 

any Covered Flare, MPC may submit a request to EPA for an 

adjustment of the Total Steam Mass Flow Rate and Total Steam 

Volumetric Flow Rate at that Covered Flare based on the Steam 

Contribution Factor at that Covered Flare. In any such request, 

MPC must demonstrate and justify the equation it proposes to use 

to calculate the Non-Mixing Total Steam at the Covered Flare that 

is the subject of the request. 

d.	 Exceptions . Notwithstanding the requirements of Subparagraphs 47.a and 

47.b, MPC is not subject to the emissions standards in those Subparagraphs if the exception in 

Paragraph 50 applies and/or in order to achieve the following: 

i.	 Stop Smoke Emissions that are occurring; 

ii.	 Meet the Net Heating Value requirements of Paragraph 46; 

iii.	 Prevent extinguishing the Flare; and/or 

iv.	 Protect personnel safety. 

48.	 Minimum Momentum Flux Ratio (MFR) for Covered Flares, except the Garyville 

Ground Flares. 

a. The requirements of this Paragraph have no applicability to Ground 

Flares; therefore, the Garyville Ground Flares are not subject to this Paragraph. All references to 

“Covered Flares” in this Paragraph exclude the Garyville Ground Flares. 

b.	 By no later than the dates set forth in Column H of Appendix 2.1, for each 

Covered Flare, MPC shall comply with either Subparagraph 48.c.i or 48.c.ii, or, for the Detroit 

46
 

Crude Flare, Subparagraph 48.d. In the first semi-annual report due after the applicable 

compliance date, MPC shall identify which compliance option it selects for each Covered Flare. 

MPC may select different alternatives for different flares. MPC subsequently may change the 

option it previously had selected for a Covered Flare but only after notifying EPA in a 

semi-annual report that it intends to make the change 30 days after submission of the report. In 

the report, MPC shall include the reason for changing the compliance option. 

c. MFR Requirements . MFR shall be calculated in accordance with the 

equations, conversion factors, MFR constants, MFR measured variables, and MFR calculated 

variables set forth in Appendix 1.5. At each Covered Flare except the Detroit Crude Flare 

(which is subject to Subparagraph 48.d), MPC shall either: 

i.	 Maintain a minimum MFR of 0.0030 on a 60-minute rolling 

average basis, rolled every 5 minutes; or 

ii.	 Propose a Flare-specific MFR. MPC shall submit such a proposal 

to EPA for approval. In any such proposal, MPC shall 

demonstrate to EPA’s satisfaction that at the proposed MFR, 

Discontinuous Wake Dominated Flow or measured Combustion 

Efficiency less than 98% will not occur for the Covered Flare that 

is the subject of the request. 

d. For the Detroit Crude Flare, MPC shall maintain a minimum MFR of 

0.00050 on a 60-minute rolling average basis, rolled every 5 minutes. 

e. Exceptions to the Applicability of the MFR Requirements. The 

requirements of Subparagraphs 48.c and 48.d are not applicable in the following circumstances: 

i.	 During any period of Vent Gas flow to the Covered Flare where 

there are less than 6 consecutive 5-minute averages of MFR; 

ii.	 At any time that the wind speed at a Covered Refinery is greater 

than or equal to 35 mph on a 60-minute rolling average basis, 

rolled every 5 minutes; and/or 

iii.	 If the exception in Paragraph 50 applies. 

47
 
f. Calculation of MFR “on a 60-minute rolling average basis, rolled every 5 

minutes,” when there are more than 5 but less than 12 consecutive 5-minute averages of MFR. 

During any period of Vent Gas flow to the Covered Flare when there are more than 5 but less 

than 12 consecutive 5-minute averages of MFR, the MFR “on a 60-minute rolling average basis, 

rolled every 5 minutes” shall be calculated using the 5-minute averages that are greater than “0” 

during the period; the 5-minute averages when MFR is “0” because there is no Vent Gas flow 

shall not be used in calculating the 60-minute rolling average, rolled every 5 minutes. 

49. 98% Combustion Efficiency . By no later than the dates set forth in Column H of 

Appendix 2.1, MPC shall operate each Covered Flare with a minimum of a 98% Combustion 

Efficiency at all times when Waste Gases are vented to it. To demonstrate continuous 

compliance with the 98% Combustion Efficiency, MPC shall operate each Covered Flare within 

the range of operating parameters set forth in Paragraphs 46–48. 

50. Exception for Instrument Downtime. A failure to comply with the work practices 

or standards in Subparagraphs 43.a, 43.b, 46.a, 46.b, 47.a, 47.b, 48.c.i, 48.c.ii, or 48.d shall not 

constitute a violation of such work practice or standard if the noncompliance results from 

downtime of instruments or equipment due to the following: 

a.	 Malfunction of an instrument, for an instrument needed to meet the 

requirement(s); 

b.	 Maintenance following instrument Malfunction, for an instrument needed 

to meet the requirement(s); 

c.	 Scheduled maintenance of an instrument in accordance with the 

manufacturer’s recommended schedule, for an instrument needed to meet 

the requirement(s); and/or 

d.	 Quality Assurance/Quality Control activities on an instrument needed to 

meet the requirement(s). 

48
 

This exception shall no longer be applicable if the activities in Subparagraphs 50.a–50.d exceed 

110 hours in any calendar quarter for any instrument. The calculation of instrument downtime 

shall be made in accordance with 40 C.F.R. § 60.13(h)(2) and Paragraph VI of Appendix 1.10. 

51. Inapplicability of Paragraphs 46–49 . The requirements of Paragraphs 46–49 are 

not applicable to any Covered Flare when the only gas or gases being vented to the Covered 

Flare is/are Pilot Gas and/or Purge Gas. 

52. Emissions and Combustion Efficiency Testing of the Garyville Ground Flares: 

Requirements. By no later than September 30, 2012, MPC shall conduct testing that evaluates 

the emissions and Combustion Efficiency of the Garyville Ground Flares. The testing shall be 

conducted in accordance with the protocol set forth in Appendix 2.4. MPC shall complete the 

testing within 30 days of commencing the test.

Vent Gas composition, and Vent Gas exit velocity; for the Garyville 

Ground Flares, a demonstration that 98% Combustion Efficiency will be 

achieved at maximum design exit velocity for the proposed NHVcz; and 

49
 
d.	 The proposed “A” Combustion Efficiency Multiplier for calculating the 

NHVcz-limit and the maximum S/VGmass and/or S/VGvol at which MPC 

proposes to operate Robinson Flare 84-F1 and the Garyville Ground Flares 

in order to achieve a Combustion Efficiency of no less than 98% on a 

continuous basis. 

54. EPA Response to Testing Reports . EPA shall review the reports required in 

Paragraph 53 and establish the “A” Combustion Efficiency Multiplier for calculating the 

NHVcz-limit and the maximum S/VGmass and/or S/VGvol for each of these Flares. These limits will 

be based on the results of the testing and a consideration of emissions impacts, and will be set at 

a point where the limits ensure that a Combustion Efficiency of at least 98% is continuously 

achieved with a reasonable certainty of compliance. Disputes arising under this Paragraph shall 

be resolved in accordance with the dispute resolution provisions of this Decree. 

55. Recordkeeping: Timing and Substance . MPC shall comply with the following

D.	 Miscellaneous 

56.	 Temporary-Use Flares. 

a. Applicability. The provisions of this Paragraph shall apply to 

Temporary-Use Flares. 

b. Distinction between Planned and Unplanned Outages of Covered Flares. 

For purposes of this Paragraph, a “planned” outage of a Covered Flare shall mean an outage that 

is scheduled 30 days or more in advance of the outage. An “unplanned” outage is an outage that 

either is scheduled less than 30 days in advance or is unscheduled. 

c. 504 hours or less . For any planned or unplanned outage of a Covered 

Flare that MPC knows or reasonably anticipates will result in 504 hours or less of downtime on a 

rolling 1095-day average period, MPC shall make good faith efforts to ensure that the 

Temporary-Use Flare that replaces the Covered Flare complies with all of the requirements of 

this Consent Decree that are applicable to the Covered Flare that the Temporary-Use Flare 

replaces. 

d.	 More than 504 hours. 

i.	 Planned. For any planned outage of a Covered Flare that MPC 

knows or reasonably can anticipate will last 504 hours or more on 

a rolling 1095-day average period, MPC shall ensure that the 

Temporary-Use Flare complies with all of the requirements of this 

Consent Decree related to the Covered Flare that it replaces as of 

the date that the Temporary-Use Flare is placed into service. 

ii.	 Unplanned. For any unplanned outage of a Covered Flare that, in 

advance of the outage, MPC cannot reasonably anticipate will last 

longer than 504 hours, MPC shall ensure that the Temporary-Use 

Flare complies with all of the requirements of this Consent Decree 

related to the Covered Flare that it replaces by no later than 30 

days after the date that MPC knows or reasonably should have 

known that the outage will last 504 hours or more. 

52
 
e. Recordkeeping . MPC shall keep records sufficient to document 

compliance with the requirements of this Paragraph any time it uses a Temporary-Use Flare. 

57. Miscellaneous. Whenever this Consent Decree requires compliance within a 

certain number of “months” after a triggering event, the compliance obligation commences on 

the anniversary of the numerical date that triggers the obligation. For example, if compliance is 

required by no later than three months after the submission of a particular document, and if the 

document is submitted on March 23, 2012, the compliance obligation commences on June 23, 

2012. 

E.	 NSPS Subpart A, J, and Ja Applicability 

58. NSPS Subparts A and J . As of the Date of Lodging, each Covered Flare shall 

continue to be an “affected facility” within the meaning of Subparts A and J of 40 C.F.R. 

Part 60; however, except as set forth in Subparagraph 59.a, each Covered Flare shall comply 

with the requirements of Subparts A and J, including all monitoring, recordkeeping, reporting, 

and operating requirements, by no later than the dates in Column J of Appendix 2.1. 

59. NSPS Subparts A and Ja. Each Covered Flare shall be an “affected facility” 

within the meaning of Subparts A and Ja of 40 C.F.R. Part 60, and shall comply with the 

requirements of Subparts A and Ja, including all monitoring, recordkeeping, reporting, and 

operating requirements, by the later of: (i) the dates in Column J of Appendix 2.1; or (ii) the 

date(s) by which a “modified” flare (within the meaning of Subpart Ja) must comply with the 

requirements of Subpart Ja. 

a.	 To the extent that the later of the two possible dates is “the dates in 

Column J of Appendix 2.1,” then Subpart Ja, and not Subpart J, is the 

applicable Subpart on and after the dates in Column J of Appendix 2.1. 

b.	 To the extent that the later of the two possible dates is “the earliest date by 

which a ‘modified’ flare (within the meaning of Subpart Ja) must comply 

53
 

with the requirements of Subpart Ja,” then Subpart J is applicable between 

the dates in Column J of Appendix 2.1 and the applicable date(s) of 

Subpart Ja. Thereafter, only Subpart Ja is applicable. 

c.	 On and after the date(s) that each Covered Flare is subject to Subpart Ja, 

Subpart J no longer is applicable to that Covered Flare. 

F.	 Incorporation of Consent Decree Requirements into Federally Enforceable Permits 

60. Permits Needed to Meet Compliance Obligations. If any compliance obligation 

under this Section V requires MPC to obtain a federal, state, or local permit or approval, MPC 

shall submit timely and complete applications and take all other actions necessary to obtain all 

such permits or approvals. MPC may seek relief under the provisions of Section X of this 

Decree (Force Majeure) for any delay in the performance of any such obligation resulting from a 

failure to obtain, or a delay in obtaining, any permit or approval required to fulfill such 

obligation, if MPC has submitted timely and complete applications and has taken all other 

actions necessary to obtain all such permits or approvals. 

61. Permits to Ensure Survival of Consent Decree Limits and Standards after 

Termination of Consent Decree . 

a. Prior to termination of this Consent Decree, for those states that do not 

have a consolidated Title V construction and operating permit program, MPC shall submit 

complete applications to applicable state/local agencies to incorporate the limits and standards 

listed in Subparagraph 61.b into non-Title V, federally enforceable permits that will survive 

termination of this Consent Decree. Prior to termination of this Consent Decree, for those states 

that have a consolidated Title V construction and operating permit program, MPC shall submit to 

the applicable state/local agencies, appropriate applications, amendments and/or supplements to 

incorporate as “applicable requirements” the limits and standards listed in Subparagraph 61.b to 

ensure that these limits and standards survive termination of this Consent Decree. 

54
 
b. The limits and standards imposed by the following Paragraphs of this 

Consent Decree shall survive termination: 17–23, 24 (if required), 26–28, 39–40, 41–45, 46.b.i, 

46.b.iv, 47.b–d, 48.c–f, 49–51, 55, 56.c (if applicable), 56.d (if applicable), and 58–59. At the 

time of submission of the documents necessary to ensure survival of the limits and standards 

identified in this Subparagraph, MPC may elect, at any Covered Flare, to cease recording both 

S/VGmass and S/VGvol and instead may identify the S/VG basis (i.e., volume or mass) that it 

elects to comply with going forward and record S/VG only on that basis. 

62. Modifications to Title V Operating Permits. Prior to termination of this Consent 

Decree, MPC shall submit complete applications to applicable state/local agencies to modify, 

amend, or revise the Title V permit of each Covered Refinery to incorporate the limits and 

standards identified in the preceding Paragraph in the Title V permits. The Parties agree that the 

incorporation of these emission limits and standards into Title V Permits shall be done in 

accordance with applicable state or local Title V rules. The Parties agree that the incorporation 

may be by “amendment” under 40 C.F.R. § 70.7(d) and analogous state Title V rules, where 

allowed by state law. 

55
 

VI. EMISSION CREDIT GENERATION 

63.	 Prohibitions . 

a.	 Definition. “CD Emissions Reductions” shall mean any NOx, SO2, H2S, 

PM, PMTOTAL, PM10, PM2.5, VOC, or CO emissions reductions that result from any projects 

conducted or controls used to comply with this Consent Decree. 

b.	 Prohibitions . 

i.	 MPC shall neither generate nor use any CD Emissions Reductions 

as netting reductions, as emissions offsets, or in determining 

whether a project is “major” in any PSD, major non-attainment, 

and/or minor New Source Review permit or permit proceeding; 

ii.	 Any CD Emissions Reductions that result from the Waste Gas 

minimization requirements of Paragraphs 30–37 may not be used 

as netting reductions, as emissions offsets, or in determining 

whether a project is “major” in any PSD, major non-attainment 

and/or minor New Source Review permit or permit proceeding 

even if those Reductions result in emissions lower than the 

allowable level under the flaring limitations in Paragraph 39. 

iii.	 Except as provided in Subparagraph 64.b, MPC shall not apply for, 

obtain, trade, or sell any emission reduction credits that result from 

CD Emissions Reductions. 

64. Outside the Scope of the Prohibition . Nothing in this Section is intended to 

prohibit MPC from seeking to nor prohibit an applicable state agency from denying MPC’s 

ability to: 

a.	 Use or generate netting reductions or emission reduction credits for 

refinery units that are not subject to an emission limitation pursuant to this 

Consent Decree; 

b.	 Use CD Emissions Reductions for a Covered Refinery’s compliance with 

any rules or regulations designed to address regional haze or the 

non-attainment status of any area (excluding PSD and Non-Attainment 

New Source Review rules, but including, for example, RACT rules) that 

apply to the Covered Refinery; provided, however, that MPC shall not be 

allowed to trade or sell any CD Emissions Reductions.

Exceedances. On and after the date of applicability of any work practice or standard, MPC shall 

provide a summary of the following, per Covered Flare per calendar quarter (hours shall be 

rounded to the nearest tenth): 

a.	 Monitoring Instrument/Equipment Downtime. The total number of hours 

of downtime of each monitoring instrument/equipment required pursuant 

to Paragraphs 18–20, 22–23, and, if applicable, 24, expressed as both an 

absolute number and a percentage of time the Covered Flare that the 

instrument/equipment monitors is available for operation; 

b.	 Monitoring Instrument/Equipment Downtime. If the total number of 

hours of downtime of any monitoring instrument/equipment required 

pursuant to Paragraphs 18–20, 22–23, and, if applicable, 24 exceeds 110 

hours in any calendar quarter, an identification of the periods of downtime 

by date, time, cause (including Malfunction or maintenance), and, if the 

cause is asserted to be a Malfunction, the corrective action taken; 

c.	 Override of Automatic Control System. The total number of hours in 

which MPC overrode the ACS required in Paragraph 43, expressed both 

60
 
an absolute number of hours and a percentage of time the Covered Flare 

was available for operation; provided however, that for any hour 

identified, the report shall describe either or both of the following: (i) if 

the reason for the override was one of the exceptions identified in 

Paragraph 44, a statement of which exception; or (ii) if the total number of 

hours in which the ACS was overrode was less than 110 hours and was 

caused by one or more of the exceptions identified in Paragraph 50, a 

statement to that effect; 

d.	 Override of Automatic Control System. If the reason for the override was 

not one of the exceptions set forth in Paragraph 44 or if the total number 

of hours in which the ACS was overrode exceeds 110 hours in any 

calendar quarter, an identification of the periods of override by the date, 

time, duration, reason for the override, and corrective actions taken; 

e.	 Inapplicability of Emissions Standards. The total number of hours in 

which the requirements of Paragraphs 46–49 were not applicable because 

the only gas or gases being vented was/were Pilot Gas and/or Purge Gas, 

expressed as both an absolute number of hours and a percentage of time 

the Covered Flare was available for operation; for purposes of 

Subparagraphs 70.f. and 70.g, all remaining hours shall be termed “Hours 

of Applicability”; 

f.	 Exceedances of Emissions Standards. During the Hours of Applicability, 

the total number of hours of exceedances of the emissions standards in 

Subparagraphs 46.b, 47.b, 48.c, 48.d, and 49, expressed as both an 

absolute number of hours and a percentage of time the Covered Flare was 

available for operation; provided however, that if the exceedance of these 

standards was less than 110 hours in the calendar quarter and was due to 

one or more of the exceptions set forth in Paragraph 50, the report shall so 

note; 

g.	 Exceedances of Emissions Standards. During the Hours of Applicability, 

if the exceedance of the emissions standards in Subparagraphs 46.b, 47.b, 

48.c, 48.d, or 49 was not due to one of the exceptions in Paragraph 50, or 

if the exceedance was due to one or more of the exceptions in 

Paragraph 50 but the total number of hours caused by the exceptions in 

Paragraph 50 was greater than 110, an identification of each averaging 

period that exceeded the standard, by time and date; the cause of the 

exceedance (including Startup, Shutdown, maintenance, or Malfunction), 

and if the cause is asserted to be a Malfunction, an explanation and any 

corrective actions taken; and 

61
 

h.	 Flaring Limitations Exceedances. 

i.	 For any Waste Gas flows that are excluded from the calculation of

ii.	 An identification of each calendar day in which the limitations on 

flaring set forth in Paragraph 39 were violated; 

iii.	 The cause of the exceedance; 

iv.	 If the cause is asserted to be a Malfunction, an explanation and any 

corrective actions taken; 

v.	 A quantification of the total excess VOC and SO2 emissions 

calculated pursuant to Appendix 1.13, as well as the calculations 

that support that quantification; and 

vi.	 The information required in Paragraph 80. 

71. Emissions Data. In the semi-annual report that is submitted on July 31 of each 

year, MPC shall provide, for each Covered Flare, for the prior calendar year, the amount of 

emissions of the following compounds (in tons per year): VOCs, SO2, H2S, CO2, methane, and 

ethane. 

72. Due Dates. The first compliance status report shall be due thirty-one days after 

the first full half-year after the Effective Date of this Consent Decree (i.e., either: (i) January 31 

of the year after the Effective Date, if the Effective Date is between January 1 and June 30 of the 

preceding year; or (ii) July 31 of the year after the Effective Date, if the Effective Date is 

between July 1 and December 31). The initial report shall cover the period between the 

Effective Date and the first full half year after the Effective Date (a “half year” runs between 

January 1 and June 30 and between July 1 and December 31). Until termination of this Decree, 

each subsequent report will be due on the same date in the following year and shall cover the 

prior two half years (i.e., either January 1 to December 31 or July 1 to June 30). 

62

or those persons directly responsible for gathering the information, the 

information submitted is, to the best of my knowledge and belief, true, accurate, 

and complete. 

74. The reporting requirements of this Consent Decree do not relieve MPC of any 

reporting obligations required by the CAA or implementing regulations, or by any other federal, 

state, or local law, regulation, permit, or other requirement. 

75. Any information provided pursuant to this Consent Decree may be used by the 

United States in any proceeding to enforce the provisions of this Consent Decree and as 

otherwise permitted by law.

rolling average limit is not the sole basis for calculating 

the stipulated penalty due. Instead, each day on which 

the 30-day rolling average limit is violated —which 

violations most likely continue even though the 

precipitating event and the excess emissions do not — 

counts as a separate day. MPC shall comply with

The amount of excess emissions during the event(s) 

which precipitate(s) the exceedance(s) of the 365-day 

rolling average limit is not the sole basis for calculating 

the stipulated penalty due. Instead, each day on which 

the 365-day rolling average limit is violated—which 

violations most likely continue even though the 

precipitating event and the excess emissions do not— 

counts as a separate day. MPC shall comply with 

Appendix 1.13 to calculate the stipulated penalties 

resulting from violating the flaring limitation in Column 

D of Paragraph 39.

noncompliance with the H2S limit, all one-hour periods 

of violation shall be added together to determine the total. 

The averaging period for this standard is a three-hour 

rolling average. 

78. Waiver of Payment . The United States may, in its unreviewable discretion, 

reduce or waive payment of stipulated penalties otherwise due to it under this Consent Decree. 

79. Demand for Stipulated Penalties (except for Stipulated Penalties Under 

Subparagraph 77.i or 77.j). Except for demands under Subparagraph 77.i or 77.j for violations of 

the flaring limitations in Paragraph 39, a written demand for the payment of stipulated penalties 

68
 

will identify the particular violation(s) to which the stipulated penalty relates; the stipulated 

penalty amount (as can be best estimated) that the United States is demanding for each violation; 

the calculation method underlying the demand; and the grounds upon which the demand is 

based. Prior to issuing a written demand for stipulated penalties, the United States may, in its 

unreviewable discretion, contact MPC for informal discussion of matters that the United States 

believes may merit stipulated penalties. 

80.	 Stipulated Penalties under Subparagraph 77.i. or 77.j . 

a. If MPC violates any of the flaring limitations in Columns C or D of 

Paragraph 39, MPC shall provide in the semi-annual report due under Section VIII of this Decree 

(Reporting Requirements) for the period in which the violation(s) first commenced, the 

information required in Subparagraph 70.h. If, as of the last day that is covered by the 

semi-annual report: 

i.	 The event(s) precipitating the violation(s) has(have) not ceased, 

MPC also shall identify any corrective measures that it took and is 

taking to limit the duration of the event(s) and an estimate of the 

expected duration of the event(s) and the violation(s); 

ii.	 The event precipitating the violation(s) has(have) ceased but the 

violation(s) has(have) not ceased because of the averaging periods 

involved, MPC also shall provide an estimate of the expected 

duration of the violation(s); or 

iii. 	 Both the event precipitating the violation(s) and the violations 

has(have) ceased, MPC also shall provide a calculation of the 

amount of stipulated penalties due. 

b. If Subparagraph 80.a.i or 80.a.ii applies, in the first semi-annual report in 

which both the event precipitating the violation(s) and the violations has(have) ceased, MPC 

shall provide a calculation of the amount of stipulated penalties due. 

69
 

c. After receipt of a semi-annual report that provides a calculation of the 

amount of stipulated penalties due for violation of the flaring limitations in Columns C or D of 

Paragraph 39, the United States may issue a written demand for stipulated penalties. Prior to 

issuing a written demand, the United States may, in its unreviewable discretion, contact MPC for 

informal discussion of the matter. 

81. Stipulated Penalties= Accrual . Stipulated penalties will begin to accrue on the 

day after performance is due or the day a violation occurs, whichever is applicable, and, except 

as provided in Paragraph 84, shall continue to accrue until performance is satisfactorily 

completed or the violation ceases. Stipulated penalties shall accrue simultaneously for separate 

violations of this Consent Decree. 

82. Stipulated Penalties Payment Due Date. Stipulated penalties shall be paid no later 

than sixty (60) days after receipt of a written demand by the United States unless the demand is 

disputed through compliance with the requirements of the dispute resolution provisions of this 

Decree. 

83. Manner of Payment of Stipulated Penalties. Stipulated penalties owing to the 

United States of under $10,000 shall be paid by check and made payable to AU.S. Department of 

Justice,@ referencing DOJ Number 90-5-2-1-09915 and USAO File Number 2011V01341, and 

delivered to the U.S. Attorney=s Office in the Eastern District of Michigan, 211 W. Fort St., 

Suite 2100, Detroit, MI 48226. Stipulated penalties owing to the United States of $10,000 or 

more shall be paid in the manner set forth in Section IV of this Decree (Civil Penalty). All 

transmittal correspondence shall state that the payment is for stipulated penalties, shall identify 

the violations to which the payment relates, and shall include the same identifying information 

required by Paragraph 13. 

70
 
84. Disputes over Stipulated Penalties. By no later than 60 days after receiving a 

demand for stipulated penalties, MPC may dispute liability for any or all stipulated penalties 

demanded by invoking the dispute resolution procedures of Section XI of this Decree (Dispute 

Resolution). In the event of a dispute over stipulated penalties, stipulated penalties shall not 

accrue commencing on the later of either: (i) the date that, during dispute resolution under 

Section XI, the United States and MPC agree upon; or (ii) the date that MPC files a motion with 

the Court under Paragraph 98; provided however, that in order for stipulated penalties to cease 

accruing pursuant to either (i) or (ii), MPC must place the disputed amount in an interest-bearing 

commercial escrow account. If the dispute thereafter is resolved in MPC’s favor, the escrowed 

amount plus accrued interest will be returned to MPC; otherwise, the United States will be 

entitled to the amount determined by the Court to be due, plus interest that has accrued on such 

amount in the escrow account. 

85. No amount of the stipulated penalties paid by MPC shall be used to reduce its 

federal tax obligations. 

86. Subject to the provisions of Section XIII of this Decree (Effect of 

Settlement/Reservation of Rights), the stipulated penalties provided for in this Decree shall be in 

addition to any other rights, remedies, or sanctions available to the United States for a violation 

of this Consent Decree or applicable law. In addition to injunctive relief or stipulated penalties, 

the United States may seek mitigating emissions reductions equal to or greater than the excess 

amounts emitted if the violations result in excess emissions. MPC reserves the right to oppose 

the United States’ request for mitigating emission reductions. MPC shall be allowed a credit, for 

any stipulated penalties paid, against any statutory penalties imposed for such violation. 

71
 

X. FORCE MAJEURE
 


87. “Force Majeure,” for purposes of this Consent Decree, is defined as any event 

beyond the control of MPC, its contractors, or any entity controlled by MPC that delays the 

performance of any obligation under this Consent Decree despite MPC’s best efforts to fulfill the 

obligation. The requirement that MPC exercise “best efforts to fulfill the obligation” includes 

using best efforts to anticipate any potential Force Majeure event and best efforts to address the 

effects of any such event: (a) as it is occurring; and (b) after it has occurred, to prevent or 

minimize any resulting delay. 

88. “Force Majeure” does not include MPC’s financial inability to perform any 

obligation under this Consent Decree. Unanticipated or increased costs or expenses associated 

with the performance of MPC’s obligations under this Consent Decree shall not constitute 

circumstances beyond MPC’s control nor serve as the basis for an extension of time under this 

Section X. 

89. If any event occurs or has occurred that may delay the performance of any 

obligation under this Consent Decree, whether or not caused by a Force Majeure event, MPC 

shall notify EPA in writing not later than fifteen calendar days after the time MPC first knew or 

should have known by the exercise of due diligence that the event might cause a delay. In the 

written notice, MPC shall specifically reference this Paragraph 89 of the Consent Decree and 

shall provide an explanation and description of the reasons for the delay; the anticipated duration 

of the delay; all actions taken or to be taken to prevent or minimize the delay; a schedule for 

implementation of any measures to be taken to prevent or mitigate the delay or the effect of the 

delay; MPC’s rationale for attributing such delay to a Force Majeure event if it intends to assert 

such a claim; and a statement as to whether, in the opinion of MPC, such event may cause or 

72
 

contribute to an endangerment to public health, welfare, or the environment. MPC shall be 

deemed to know of any circumstance of which MPC, any entity controlled by MPC, or MPC’s 

contractors knew or should have known. MPC shall include with any notice all available 

documentation supporting the claim that the delay was attributable to a Force Majeure. The 

written notice required by this Paragraph shall be effective upon the mailing of the same by 

overnight mail or by certified mail, return receipt requested, to EPA in the manner set forth in 

Section XV of this Decree (Notices). 

90. Failure by MPC to comply with the requirements in Paragraph 89 shall preclude 

MPC from asserting any claim of Force Majeure for the event for the period of time of such 

failure to comply, and for any additional delay caused by such failure. 

91. If EPA agrees that the delay or anticipated delay is attributable to a Force Majeure 

event, the time for performance of the obligations under this Consent Decree that are affected by 

the Force Majeure event will be extended by EPA for such time as is necessary to complete those 

obligations. An extension of the time for performance of the obligations affected by the Force 

Majeure event shall not, of itself, extend the time for performance of any other obligation. EPA 

will notify MPC in writing of the length of the extension, if any, for performance of the 

obligations affected by the Force Majeure event. 

92. If EPA does not agree that the delay or anticipated delay has been or will be 

caused by a Force Majeure event, or if the EPA and MPC fail to agree on the length of the delay 

attributable to the Force Majeure event, EPA will notify MPC of its decision. 

93. If MPC elects to invoke the dispute resolution procedures set forth in Section XI 

of this Decree (Dispute Resolution), it shall do so no later than 45 days after receipt of EPA’s 

notice. In any such proceeding, MPC shall have the burden of demonstrating by a 

73
 
preponderance of the evidence that the delay or anticipated delay has been or will be caused by a 

Force Majeure event, that the duration of the delay or the extension sought was or will be 

warranted under the circumstances, that best efforts were exercised to avoid and mitigate the 

effects of the delay, and that MPC complied with the requirements of Paragraphs 87 and 89. If 

MPC carries this burden, the delay at issue shall be deemed not to be a violation by MPC of the 

affected obligation of this Consent Decree identified to EPA and the Court. 

XI. DISPUTE RESOLUTION 

94. Unless otherwise expressly provided for in this Consent Decree, the dispute 

resolution procedures of this Section shall be the exclusive mechanism to resolve disputes arising 

under or with respect to this Consent Decree. 

95. Informal Dispute Resolution . The first stage of dispute resolution shall consist of 

informal negotiations. The dispute shall be considered to have arisen when one Party sends the 

other Party a written Notice of Dispute. Such Notice of Dispute shall state clearly the matter in 

dispute. The period of informal negotiations shall not exceed 60 days after the Notice of 

Dispute, unless that period is modified by written agreement. If the Parties cannot resolve the 

dispute by informal negotiations, then the position advanced by the United States shall be 

considered binding unless within 45 days after the conclusion of the informal negotiation period, 

MPC invokes formal dispute resolution procedures set forth below. 

96. Formal Dispute Resolution. MPC shall invoke formal dispute resolution 

procedures, within the time period provided in the preceding Paragraph, by serving on the United 

States a written Statement of Position regarding the matter in dispute. The Statement of Position 

shall include, but need not be limited to, any factual data, analysis, or opinion supporting MPC’s 

position and any supporting documentation relied upon by MPC.

right to argue to the contrary. 

75
 
101. The invocation of dispute resolution procedures under this Section shall not, by 

itself, extend, postpone, or affect in any way any obligation of MPC under this Consent Decree,

information-retention requirement shall apply regardless of any contrary corporate or 

institutional policies or procedures. At any time during this information-retention period, the 

United States may request copies of any documents, records, or other information required to be 

76
 

maintained under this Paragraph. MPC shall retain the data recorded by any video camera 

required pursuant to Paragraph 24 for six months from the date of recording except that MPC 

shall keep any such video record until one year after termination if MPC was required to keep 

the record pursuant to Subparagraph 55.c.

States for injunctive relief, civil penalties, other appropriate relief relating to the Covered 

Refineries or MPC’s CAA violations, MPC shall not assert, and may not maintain, any defense 

or claim based upon the principles of waiver, res judicata, collateral estoppel, issue preclusion, 

claim preclusion, claim-splitting, or other defenses based upon any contention that the claims 

raised by the United States in the subsequent proceeding were or should have been brought in the 

instant case, except with respect to claims that have been specifically resolved pursuant to 

Paragraphs 107–112 of this Section and for which the resolution of liability has not been voided 

pursuant to Paragraph 113. 

116. This Consent Decree is not a permit, or a modification of any permit, under any 

federal, state, or local laws or regulations. MPC is responsible for achieving and maintaining 

complete compliance with all applicable federal, state, and local laws, regulations, and permits; 

and MPC’s compliance with this Consent Decree shall be no defense to any action commenced

does not, by its consent to the entry of this Consent Decree, warrant or aver in any manner that 

MPC’s compliance with any aspect of this Consent Decree will result in compliance with 

provisions of the Act, 42 U.S.C. § 7401 et seq., or with any other provisions of federal, state, or 

local laws, regulations, or permits.

NlWCl. 

Equation Sb u....s volumetric flow rates for the calculation of "'''V..: 

The ideal gas law provides a method for determining volumetric now rate of a speci fic gas. k In 

the combustion zone at standard conditions : 

"'. -to,73 ' 528 m. Q. '"' ""w••14,696 '"' 385.5 NW. 

Subslitutiun of this l.'llpR'Ssion inlU Equation Sb gives NIIV" in teons of mass now:

NII V", " , , ill " 3BS.5~ -+ .5~ -+ 38!>.5~ + 385,5

Because the combustio n zone is well-mixed, eac h gaseous component of the combustion LIm e is 

at the same temperature and pressure. Thus. the last expression reduces to Equatiun Sa: 

9 01'10 
This demonstrates the equivalence ofEqualiuns Sa and Sb.

Momentum Flux Ratio (MFRI is 11M: teladonship between the: density (P) and 'c1ocil o f lhe

The numerator of me fraction is the "momentum flux" of ihe v em Gas plus Center Steam and 

the denominator is the "momenlum Ilux" uf the air (wirld). As 11M: veIO\:it), orthe winll 

increases. the MFR willdecline for a gsven Venl Gas composition and 110.... rate .

WAST E GAS MAPPING: LEVEL OF DETAIL 

NEEDED TO SHOW MAIN HEADERS AND 

PROCESS UNIT HEADERS 
API'E NDIX 1.11 

WASTE GAS MAPPING : 

LEVEL OF DETAIL NEEDED TO SHOW MAIN HEADERS 

AND PROCESS UNIT HEADERS 

Purpose: 

Waste Gas Mapping is required in order to identify the sourcets) of waste gas entering 

each Covered Flare. Waste Gas Mapping can be done using instrumentation, isotopic 

tracing, acoustic monitorin g. and/or engineering estimates for all sources entering a 

flare header (e,g pump seal purges. sample station purges, compressor seal nitrogen 

purges, relief valve leakage, and other sources under normal operations). This 

AppendilC oullines what needs to be included as the Waste Gas Mapping section within 

the Initial Waste Gas Minimization Plan ("Initial WGMP") 

Waste Gas Mapping Criteria: 

For purposes of waste gas mapping, a main header is defined as the last pipe segment 

prior to the flare knock out drum. Process unit headers are defined as pipes from inside 

the battery limits of each process unit that connect to the main header. For process unit 

headers that are greater than or equal to six (6) inches in diameter, flow ("OJ musl be 

identified and quantified if it is technically reasible 10 do so. In addition, all sources 

feeding each process unit header must be identified and listed in a table. but not 

necessarily individually quantified. For process unit headers that are less than S;lC (6) 

inches in diameter, sources must be identified. but they do not need 10 be quantified 

Waste Gas M apping Submission Requirements: 

For each Covered Flare, the following shall be included Within the Waste Gas Mapping 

section of the Initial WGMP: 

1. Simplified Schematic consis tent with the example schematic included on the second 

page of this Appendix. 

2. Table of all sources connected to each flare main header and process unit header 

consistent with the Table included on the third page of this Appendix .

MIR is the measured signal from the calibration source using the IR source and Mn is the

measured cold source as defined earlier. The only term not defined is Io. This is the socalled synthetic background. It is frequently used in open-path FTIR measurements to

convert a measured spectrum to transmission. It represents the shape of the spectrum that

the PFTIR would measure if no gases were present. It can be synthesized from the (MIR

— Mn) measurement by doing a mathematical fit to points in the spectrum known to be

free of molecular absorptions. An example is given'in Figure B-3. In this Figure, the

bottom plot is the measured spectrum (here a relatively clean spectrum done in the

laboratory), the middle plot the points chosen for fitting, and the top plot the

mathematical fit to the chosen points. The top plot is the Io spectrum.
