P001 / Glycol dehydration unit (includes contact tower or absorption column and glycol dehydration unit reboiler) and Gas-condensate-glycol (GCG) separator (flash separator) controlled by an enclosed combustion or a vapor recovery device

a)  This permit document constitutes a permit-to-install issued in accordance with ORC 3704.03(F) and a permit-to-operate issued in accordance with ORC 3704.03(G).

(1)  For the purpose of a permit-to-install document, the emissions unit terms and conditions identified below are federally enforceable with the exception of those listed below which are enforceable under state law only.

a.  None.

(2)  For the purpose of a permit-to-operate document, the emissions unit terms and conditions identified below are enforceable under state law only with the exception of those listed below which are federally enforceable.

a.  None.

b)  Applicable Emissions Limitations and/or Control Requirements

(1)  The specific operation(s), property, and/or equipment that constitute each emissions unit along with the applicable rules and/or requirements and with the applicable emissions limitations and/or control measures are identified below. Emissions from each unit shall not exceed the listed limitations, and the listed control measures shall be specified in narrative form following the table.

/ Applicable Rules/Requirements / Applicable Emissions Limitations/Control Measures /
a. / OAC rule 3745-31-05(A)(3), as effective 11/30/01 / Emissions of Volatile Organic Compounds (VOC) shall not exceed:
XX lb/hr and
XX tons/year.
See b)(6)(a)
b. / OAC rule 3745-31-05(A)(3)(a)(ii),
as effective 12/01/06 / See b)(6)b.
c. / Part 63, Subpart HH, National Emission Standards for HAP from Oil and Natural Gas Production Facilities,
40 CFR 63.771(c)
or
ORC 3704.03(T) / The emissions from the glycol dehydration unit shall be vented through a closed-vent system, designed and operated with no detectable emissions, to a control device meeting the requirements of §63.771(d).
d. / OAC rule 3745-17-07(A)(1)(a) / The emission limitation specified by this rule is less stringent than the emission limitation established pursuant to 40 CFR 63.771(c) for a closed-vent system.

(2)  Additional Terms and Conditions

a.  The permittee has satisfied the Best Available Technology (BAT) requirements pursuant to OAC paragraph 3745-31-05(A)(3), as effective November 30, 2001, in this permit. On December 1, 2006, paragraph (A)(3) of OAC rule 3745-31-05 was revised to conform to ORC changes effective August 3, 2006 (S.B. 265 changes), such that BAT is no longer required by State regulation for NAAQS pollutant less than ten tons per year. However, that rule revision has not yet been approved by U.S. EPA as a revision to Ohio’s State Implementation Plan (SIP). Therefore, until the SIP revision occurs and the U.S. EPA approves the revision to OAC rule 3745-31-05, the requirement to satisfy BAT still exists as part of the federally–approved SIP for Ohio. Once U.S. EPA approves the December 1, 2006 version of 3745-31-05, then these emission limits/control measures no longer apply.

b.  These rule paragraphs apply once U.S. EPA approves the December 1, 2006 version of OAC rule 3745-31-05 as part of the State Implementation Plan.

i.  The Best Available Technology (BAT) requirements under OAC rule 3745-31-05(A)(3) do not apply to the Sulfur Dioxide (SO2), Nitrogen Oxides (NOx), Particulate Emissions (PE) and Carbon Monoxide (CO) from this air contaminant source since the uncontrolled potential to emit for SO2, NOx, PE and CO are less than ten tons per year.

c.  The estimated emissions of hazardous air pollutants (HAP), calculated from the designed maximum natural gas and hydrocarbon liquid throughput to the glycol dehydration units and losses from the storage vessels with the potential for flash emissions, demonstrate this facility to be an “area source” of HAP.

[40 CFR 63.760(a)] and [40 CFR 63.761]

d.  The gas stream from the glycol dehydration unit reboiler vent and glycol dehydration unit process vent shall be vented through a closed-vent system to a control device meeting the requirements of §63.771.

[40 CFR 63.771] and/or [ORC 3704.03(T)]

e.  The provisions of 40 CFR Part 60 Subpart HH shall apply at all times, except during startups, shutdowns, malfunctions, and periods of non-operation. The owner/operator shall not shut down equipment that is required to be utilized for compliance during times when emissions are being routed to such equipment. The owner/operator shall implement, to the extent reasonably available, measures to prevent or minimize emissions to the maximum extent possible during startup, shutdown, and malfunctions.

[40 CFR 63.762(a), (b), and (c)]

f.  The facility must prepare a startup, shutdown, and malfunction plan, as required in §63.6(e)(3), if not meeting the exemptions in §60.764(e), i.e., having an average flowrate of natural gas to the glycol dehydration greater than 85,000 scm/day or having an actual average benzene emission rate from the glycol dehydration process vent more than 0.90 MG/year, and if also located in a UA plus offset and UC boundary (as defined in §63.761).
