SUBJECT: Equipment Leak Emission Reduction and Cost Analysis for Well Pads, Gathering

and Boosting Stations, and Transmission and Storage Facilities Using Emission and Cost Data from the Uniform Standards

In assessing the ample margin of safety (AMO S) for the oil and natural gas production national emissions standards for hazardous air pollutants (NESHAP, 40 CFR part 63, subpart HH) and the natural gas transmission and storage NESHAP (40 CFR part 63, subpart HHH) under section 112(f)(2) of the Clean Air Act (CAA), the EPA evaluated the risk reductions and costs associated with various emission control options to determine whether they should impose additional standards to reduce risks further. The EPA determined that the risks associated with the le v el of emissions allowed by the MACT standards in subparts HH and HHH were driven by fugitive emissions (i.e., leaks). Since a LDAR program is the typical method for reducing emissions from fugitive sources, the costs and emission reductions associated with requiring such a program were evaluated for the oil and natural gas production and natural gas transmission and storage source categories.

The purpose of this memorandum is to present the results of the equipment leak cost and emission reduction analys e s for the oil and natural gas production and the natural gas transmission and storage source categories

. This analysis was conducted using the emission reductions and cost data outlined in the supporting documentation for the Uniform Standards (US) for Eq uipment Leaks rule (40 CFR part 65, subpart J) 1 that the EPA proposed on February 24, 2012 (“the US memorandum”). Nationwide costs and emission reductions were estimated using the 2005 NEI data set, which was also used to conduct the risk analysis for the oil and natural gas production and the natural gas transmission and storage source categories

1 .0 UNIFORM STANDARDS DATA AND METHODOLOGY
With the exception of natural gas processing plants (NGPP) in the production source category, facilities are not re quired to implement an LDAR program to reduce emissions from equipment leaks under subpart HH. Subpart HHH does not require an LDAR program for any facilities in the natural gas transmission and storage source category. In the production source category, HAP emissions and costs will be evaluated for well heads and gathering and boosting stations

. Since we are unable to accurately differentiate natural gas processing plants from other facilities within our NEI database we chose to characterize all facilit ies in the group comprised of well head and gathering and boosting st ations. This was done so we do not understate the overall emissions reduction in our assessment . In the transmission and storage source category, HAP emissions and costs will be evaluated for transmission compressor stations and storage facilities. The costs and emission reductions associated with implementing an LDAR program for these two source ca tegories were estimated for each type of facility in each source category from the following equipment: valves in gas/light liquid service, connectors, open

- ended lines (OEL) and pressure relief devices (PRD).

The US memorandum provides emission factors and equipment leak frequency data for several different control options. The l eak frequency refers to the estimated percentage of equipment that will be found leaking for a given leak definition. Emission factors are the estimated leak rates of an equipm ent type at a given leak definition and are normally given in kg/hr/piece of equipment. The leak frequencies and emission factors are provided in the US memorandum for the following:

 U ncontrolled equipment,

 E quipment controlled to a level equivalent to t he requirements in the Standards of Performance for Equipment Leaks of volatile organic compounds (VOC) in the Synthetic Organic Compound Manufacturing Industry for which Construction, Reconstruction or Modification Commenced After January 5, 1981, but bef ore November 7, 2006 (40 CFR part 60, subpart VV) ; 3 and

 Equipment controlled to a level equivalent to the requirements in the Standards of Performance for Equipment Leaks of VOC in the Synthetic Organic Compound Manufacturing Industry for which Constructio n, Reconstruction or Modification Commenced After November 7, 2006 (40 CFR part 60, subpart VVa).

The subpart VV control level calls for monthly Method 21 monitoring for valves with a leak definition of 10,000 parts per million ( ppm ) , sensory monitoring for connectors, installation of a cap or comparable device for open

- ended lines (OEL) , and operation with no detectable emissions (or installation of rupture disk or closed vent system ( CVS ) /air pollution control device) for pressure r elief devices (PRD)

.

3 These requirements are also equivalent to the National Emission Standard for Equipment Leaks (Fugitive Emission Sources) in 40 CFR part 61, subpart V3

The subpart VVa level of control includes a leak definition for v alves in g as / l ight l iquid service of 500 ppm (compared to 10,000 ppm at for subpart VV ) , instrument monitoring for c onnectors in g as / l ight l iquid service at a leak defi nition of 500 ppm , and annual monitoring for PRD and OEL

. Emissions Reductions for Control Options

Table 1 presents the emission factors for uncontrolled equipment, equipment controlled to the subpart VV level of control, and equipment controlled to the subpart VVa level of control. The emission factor for pressure relief valves were assumed to be leaki ng at the rate of emissions below a 500 ppm leak definition using EPA leak rate curves. 4 The emission factors presented in Table 1 were used for estimating emissions from the well pad and gathering and boosting station model plants. Uncontrolled emission f actors for the transmission compressor stations and storage facilities were based on data obtained from a GRI/EPA document 5 and emission reductions were calculated using the percent reductions calculated for the production control options presented in Tabl e 1. The component counts for the well pads, gathering and boosting stations, and transmission and storage facilities were based on data obtained from a GRI/EPA document 6 and the Oil and Natural Gas Sector Technical Support Document. 7 HAP to VOC ratios of 0.0377 by weight for production and 0.0297 by weight for transmission and storage were used to calculate HAP emissions as a portion of the VOC emissions. 8 Table 2 presents the emissions by component count for each facility type.
For the purposes of making the ample margin of safety determination under CAA section 112(f)(2), the cost impact of implementing an LDAR program on facilities in the oil and natural gas production and natural gas transmission and storage source categories was assessed using the 200 5 NEI data. Attachments 1 and 2 present the fugitive emissions data in the 2005 NEI for production and transmission and storage facilities, respectively. Because we could not distinguish between specific equipment components in the NEI data, the emission reductions were assessed on a facility

- wide basis. Table 3 presents a summary of the data in Attachments 1 and 2. We also could not distinguish between the types of production facilities and the types of transmission and storage facilities. As a result, w e calculated the average emission reduction associated with well pads and gathering and boosting stations and applied this emission reduction to the HAP emissions from production facilities in the NEI. Likewise, we calculated the average the emission redu ction for transmission compressor stations and storage facilities and applied this reduction to the HAP emissions from transmission and storage facilities in the NEI.

Costs Associated with Implementation of Subparts VV

- and VVa

- Level of Control

Because wellheads, gathering and boosting stations, transmission compressor stations, and storage facilities are not currently regulated under su b parts HH and HHH, the costs associated with implementing LDAR programs include startup costs as sociated with beginning an LDAR program. For both subpart VV and VVa

- level of control the initial and annual monitoring fees for each of the components were obtained from the US memorandum. The cost calculations are detailed in Attachment 3 for the subpar t VV level of control and Attachment 4 for the subpart VVa level of control. Individual facility capital and annual costs are presented in Table 4 and nationwide capital and annual costs as well as cost effectiveness are presented in Table 5.5 Table 1.

a Emission factors for production based on factors presented in the US memorandum for Refinery Models. Refinery models were assumed to best represent oil and natural gas production facilities (See Reference 1 ). b Subpart VV requires monthly monitoring of valves and a leak definition of 10,000 ppm, sensory monitoring for connectors, installation of a cap or comparable device for OEL, and operation with no detectable emissions (or installation of ruptur e disk CVS/air pollution control device) for PRD. R epresented in US memorandum as baseline (See Reference 1 ).

c Subpart VVa defines a leak for valve s at 500 ppm and requires instrument monitoring for connectors and a leak definition of 500 ppm. Represented in US memorandum as Valve Option 1 and Connectors Option 1. (See Reference 1 ). d No additional emission reduction is expected by requiring annual monitoring for subpart VVa level of control.

e Uncontrolled emission factors for transmission and storage facilities based on EPA/GRI docu ment 9 and emission reduction associated with subpart VV and VVa for production was applied to calculate the emissions associated with subparts VV and VVa for transmission.
