Section 03 - Description of Project
The source is requesting to permit an existing LP separator and VRT. Gas from these units had been routed to a VRU and recycled to the sales gas line. Now, the
gas will be routed to an enclosed flare.
The source asked to combine the emission and process limits for AIRS ID 008 and 009 since the amount emitted from each unit will depend on pressure and flow,
Since there isn't an emission standard for either unit, it is acceptable to have a combined Limit. Further, the source will have to demonstrate compliance by
monitoring flow from each unit and using emission factors for each stream since the streams will have different compositions. The source will be required to
accurately estimate emissions from each piece of the separation equipment but has some flexibility by demonstrating compliance with a combined emission and
process limit.

lives, the permit will contain an 'Initial Compliance" testing requirement to collect a site -specific gas sample from the equipment being permitted and conduct an emission factor
analysis to demonstrate that the emission rectors are less than or equal to the emissions factors established with this appli®tion.
Are facility -wide permitted emissions of VOC greater than or equal to 90 tons per year? No
If yes, the permit will contain an 'Initial Testing Requirement' to collect a site -specific gam sample from the equipment being permitted and conduct an emission factor analysis to
demonstrate that the emission factors are less than or equal to the emissions factors established with this application.
IF yes, the permit will contain a "Periodic Testing Requirement" to collect a site-specHlc gas sample from the equipment being permitted and conduct an emission factor analysis to
demonstrate that the emission factors are less than or equal to the emissions factors established with this application on an annual Oasis.
Will the opeator have a meter installed and operational upon startup of this point? Yes
if no, the permit will contain a condition that requires the operator to calculate gas throughput using the liquid throughput until the meter Is Installed and operational not to
exceed 180 days(. This condition will use the value In cell 031 (scf/bbl(
Does the company request a control desire efficiency greater than 95% for a flare or combustion device?
If yes, the permit will contain and initial compliance test condition to demonstrate the destruction efficiency of the combustion device based on
Inlet and outlet concentration sampling
Using Liquid Throughput to Monitor Compliance
Does the company use site specific emission factors based on a ;Hemmed liquid sample and process simulation to
estimate emissions?
if yes, are the emissions factors based on an pressurized liquid sample drawn at the facility and from equipment located upstream of the
permitted equipment? This sample should he considered representative which generally means site -specific and collected within one year of the
application received date- However, if the facility has not been modified (e.g , no new wells brought on-line(, then it may be appropriate to use an
older site -specific sample
