EPA’s New Source Performance Standards, Subpart OOOO (aka NSPS Quad O) Applicable to Crude Oil and Natural Gas
Production, Transmission and Distribution Final rule published August 16, 2012 Affects many activities after August 23, 2011 Targets VOC emissions, not methane Natural gas focused, but not exclusively

![Page 9: Avoid Air-rors! Discuss the Air Regulations that Impact Oil and Gas Development](https://reader036.fdocuments.in/reader036/viewer/2022062706/557c68f5d8b42a3e2c8b5122/html5/thumbnails/9.jpg)
Primary Impacts from Quad O Natural Gas Production
Hydraulic Fracturing - Green Completions
Oil and/or Natural Gas Compressors (centrifugal -
wet seal controls; reciprocating - rod packing replacement)
Pneumatic controllers (zero bleed at gas plants, low bleed everywhere else)
Storage vessels (controls if emit > 6 tons VOCs/year)
Also, significant recordkeeping and reporting requirements.
Gas Plants (tighter LDAR requirements)

Quad O – Storage Tank Reconsideration EPA finalized “reconsideration” of storage tank
control requirements on September 23, 2013. Final rule is more stringent EPA significantly underestimated the number of
effected storage tanks Group 1 (between August 23, 2011 and April 12,
2013) – controls after April 15, 2015. Emissions evaluation by October 15, 2013.
Group 2 (after April 12, 2013) – controls by April 15, 2014

Other Air Regulations EPA Power Plant NSPS Rule Colorado’s proposed Regulation 7 California 2013 law to regulate CO2 EOR
projects used for carbon sequestration
![Page 12: Avoid Air-rors! Discuss the Air Regulations that Impact Oil and Gas Development](https://reader036.fdocuments.in/reader036/viewer/2022062706/557c68f5d8b42a3e2c8b5122/html5/thumbnails/12.jpg)
Air Permitting and CO2
CO2 is an “air pollutant” (U.S. Supreme Court; Massachusetts vs. EPA, 2007)
EPA “Endangerment Finding” – 2009 Automobile tailpipe emission standards
So how does this affect you?
![Page 13: Avoid Air-rors! Discuss the Air Regulations that Impact Oil and Gas Development](https://reader036.fdocuments.in/reader036/viewer/2022062706/557c68f5d8b42a3e2c8b5122/html5/thumbnails/13.jpg)
Major Source Air Permitting EPA’s “Tailoring Rule”
Major source permitting thresholds (100 tons/year of pollutants) would result in “absurd results” - EPA established a 25,000 tons/year threshold for CO2
Projects that are major for CO2 must consider Best Available Control Technology (BACT)
CCS is not “mature” and most CO2 BACT to date has focused on energy efficiency
![Page 14: Avoid Air-rors! Discuss the Air Regulations that Impact Oil and Gas Development](https://reader036.fdocuments.in/reader036/viewer/2022062706/557c68f5d8b42a3e2c8b5122/html5/thumbnails/14.jpg)
NSPS Subpart OOOO (“Quad O”) Leak Detection and Repair Greenhouse Gas (GHG) Inventory/Reporting Optical Gas Imaging with Infrared Cameras
Today’s Agenda
![Page 15: Avoid Air-rors! Discuss the Air Regulations that Impact Oil and Gas Development](https://reader036.fdocuments.in/reader036/viewer/2022062706/557c68f5d8b42a3e2c8b5122/html5/thumbnails/15.jpg)
Leak Detection and Repair (LDAR)
What is LDAR? A systematic evaluation of leaking components
(valves, pumps, flanges, connectors, relief valves, etc.) for fugitive leakage of organic compounds to the atmosphere.
EPA Method 21 – a formal method using calibrated instruments to measure fugitive leakage
Optical gas imaging – uses a special infrared camera that can “see” fugitive emission leaks
![Page 16: Avoid Air-rors! Discuss the Air Regulations that Impact Oil and Gas Development](https://reader036.fdocuments.in/reader036/viewer/2022062706/557c68f5d8b42a3e2c8b5122/html5/thumbnails/16.jpg)
LDAR and NSPS OOOO
Process Unit Definition Need to accurately define process unit boundaries Be sure the Management of Change process
captures LDAR-type changes NSPS OOOO triggers will be for affected process
units, not the entire facility
![Page 17: Avoid Air-rors! Discuss the Air Regulations that Impact Oil and Gas Development](https://reader036.fdocuments.in/reader036/viewer/2022062706/557c68f5d8b42a3e2c8b5122/html5/thumbnails/17.jpg)
LDAR and MACT HH
MACT HH applies to gas plants with glycol dehydrators (major sources or area sources)
Major sources have > 1 ton/year benzene emissions, with LDAR streams > 10% volatile organic HAPs (VOHAP)
2012 MACT HH LDAR leak definition changed to 500 ppm valves/2,000 ppm pumps
![Page 18: Avoid Air-rors! Discuss the Air Regulations that Impact Oil and Gas Development](https://reader036.fdocuments.in/reader036/viewer/2022062706/557c68f5d8b42a3e2c8b5122/html5/thumbnails/18.jpg)
LDAR Implications
One facility can have components subject to NSPS KKK, NSPS OOOO, and MACT HH
Carefully evaluate facility changes

Leaking Gas = $$$
A leak at 60 gph methane equates to about $134.00 per leak per year
Average 100 leaks per facility and each leak is 10 times the rate of 60 gph the total money lost in gas is $133,567.00 per year
