MEMORANDUM

DATE: April 17, 2012

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

FROM: Bradley Nelson, EC/R Incorporated

TO: Greg Nizich, EPA/OAQPS/SPPD/FIG

Bruce Moore, EPA/OAQPS/SPPD/FIG

In assessing the ample margin of safety (AMOS) 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 level 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 analyses 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 Equipment Leaks rule (40 CFR part 65, subpart J)1that 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 required 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 facilities in the group comprised of well 

head and gathering and boosting stations. 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 categories 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 leak 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 equipment 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:

 Uncontrolled equipment, 

 Equipment controlled to a level equivalent to the 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 before 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 Construction, 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 relief 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 V
3

The subpart VVa level of control includes a leak definition for valves in gas/light liquid service 

of 500 ppm (compared to 10,000 ppm at for subpart VV), instrument monitoring for connectors 

in gas/light liquid service at a leak definition 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 leaking at the rate of emissions 

below a 500 ppm leak definition using EPA leak rate curves.4The emission factors presented in 

Table 1 were used for estimating emissions from the well pad and gathering and boosting station 

model plants. Uncontrolled emission factors for the transmission compressor stations and storage 

facilities were based on data obtained from a GRI/EPA document5and emission reductions were 

calculated using the percent reductions calculated for the production control options presented in 

Table 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 document6and 

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.8Table 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 

2005 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, we 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 reduction 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 subparts HH and HHH, the costs associated 

with implementing LDAR programs include startup costs associated 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 subpart 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.

aEmission 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 rupture disk CVS/air pollution control device) for PRD. Represented in US memorandum as baseline 

(See Reference 1).

Subpart VVa defines a leak for valves 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).

dNo additional emission reduction is expected by requiring annual monitoring for subpart VVa level of control.

eUncontrolled emission factors for transmission and storage facilities based on EPA/GRI document9

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.
