• Where to get Help…..Make this Painless
US oil production hits 25-year high: DEC 04, 2013
• Domestic crude oil production in September hit the highest monthly output since 1998, according to the U.S. Energy Information Administration (EIA).
• Oil production yielded 6.5 million barrels per day in September, EIA said. Daily production increased by 900,000 barrels daily compared with last September.
WHY IT MATTERS THAT WE GET IT RIGHT
October, 2012 the International Energy Agency projects North American oil production to overtake Saudi Arabia by 2020
WHY IT MATTERS THAT WE GET IT RIGHT
Concerns about air impacts in new and existing areas have led to increased monitoring and studies
The question is, what are these studies telling us?
WHY IT MATTERS THAT WE GET IT RIGHT
• Methane leakage rate from natural gas production is unclear, but became clearer very recently!
• EPA 2013 estimates leakage ~ 1.65% of total production; but this is about 204% ↑ from EPA’s pre-2010 estimates
• API/ANGA estimates methane emissions 50% ↓ than EPA 2011 estimates (robust data set)
• Various academic studies - ~3 % to 9%
• REAL WORLD FIELD DATA
Control Requirements:Colorado Statewide
• Tank standards: New and existing condensate tanks emitting 20 tons per year or more of Volatile Organic Compounds (VOC) required to control emissions by 95 percent.
Odors (Rule 805)
General. Oil and gas facilitiesand equipment shall be operated insuch a manner that odors and dustdo not constitute a nuisance orhazard to public welfare.
NSPS OOOO Storage Vessel Update
• Proposal Publication: April 12, 2013
• Draft Final Rule Posted by EPA August 5, 2013
• Direct Final AdoptionSeptember 23, 201378 FR 58416-58448
EPA Amends Definition of Storage Vessel Affected Facility • A single storage vessel located in the oil and
natural gas production segment, natural gas processing segment or natural gas transmission and storage segment and has the potential for VOC emissions equal to or greater than 6 tpy taking into account requirements under a legally and practically enforceable limit in an operating permit or by other mechanism.
Threshold based on potential to emit VOCs - 6 tons per year or more
Daily equivalents could be as low as:– 33 pounds emission– About 1 mcf emission– 1 barrel of condensate produced – 20 barrels of oil produced – 2000 barrels of water with 1% oil carryover processed
Applicability Date
• Same as current rule = August 23, 2011• Replacement storage vessel is considered
a new source and an affected facility if it has PTE* of 6 tpy or more and is put into service after August 23, 2011
Applicability Groups
• 3 Groups based on construction date, modification date, and PTE*: • Not an Affected Facility• Group1 • Group 2
Group 1
Group 2
Not An Affected Facility
Determination of Affected Facility
• Each storage tank or vessel • Date of installation, reconstruction,
modification– Prior to Aug 23, 2011 (not affected)– Aug 23, 2011 to April 12, 2013 (Group 1)– After April 12, 2013 (Group 2)
Affected Facility PTE Determination
• Each liquid type (crude, condensate, intermediate hydrocarbons, produce water)
• Site-specific / representative constituent analysis
• Site-specific actual maximum average daily throughput during the 30-days prior to Group 1 or 2 deadline
Affected Facility PTE Determination
• Accepted emission calculation methods for flash, working, breathing losses
• Capture effectiveness• Control effectiveness• Alternate Operating Scenarios• Planned maintenance, start-ups &
shutdowns
• VRUs are an acceptable method of routing of emissions back to the process. We really consider them part of the process, rather than an add-on control. If the storage vessel's potential to emit (PTE) is less than 6 tpy (and this is considering any enforceable permit the operator may have) then the tank is not subject.
Group 1• Storage vessels constructed or modified
between August 23, 2011 and April 12, 2013• PTE of 6 tpy or greater • Initial determination by October 15, 2013• Initial notification by
January 15, 2014• Control required by
April 15, 2015
Group 2
• Constructed or modified after April 12, 2013• PTE of 6 tpy or greater • Applicability determination and control
by April 15, 2014 or 60 days after startup, whichever is later
Emission Limitations
• Proper capture • 95% control
– 40 CFR 60.18 (flares)– Vapor combustors– Vapor recovery units (Process unit…not
a control device)
Once In – Always In
• Storage vessel affected facilities that have decreased emissions below the 6 tpy threshold remain affected facilities
Alternative Compliance
• Sustained uncontrolled emissions less than 4 tpy for 12-mo (confirm every month)
• Option to remove controls• Remain affected facilities (records,
monitoring, etc.)• If increase emissions to 4 tpy or more,
must achieve 95% control– 30 days or– Immediately on handling liquids if re-frack well
More Changes to Come
• Reconsidering monitoring and testing requirements by end of 2014.
• Temporary monitoring and testing while reconsideration is ongoing
• EPA is considering requiring a more robust compliance certification process for enclosed combustors
• EPA guidance –auto-ignite flares
Drivers:
FLIR GasFinder camera/ FlyoversRealization that existing inventories understated
Vent gas controversy in the Barnett Shale (Benzene)
Public more aware than ever
Not always the AnswerIF YOU CAN MAKE MONEY
• We agree that it is better to recover resources than to burn them. (However, by law, if someone meets the 95 percent control requirement, we cannot specify how they must meet it. In other cases, where we cannot set a numerical limit, we can set work practice or equipment standards, but there are specific criteria we must meet in order to do so.)
Welcome to Mordor, North Dakota
A Barrel of Crude Oil is Worth $164,000 – The Human Labor Equivalent of a Barrel of Oil
A single barrel of oil there is the energy equivalent of 23,000 human labor hours. This amounts to 12 years (40 hours per week)

GAS COMING OUT OF SOLUTION
Division now issuing Immediate Notice of Violation for visible emissions from a flare and/or open thief hatch.
“The Division has determined that improperly secured thief hatches, visible emissions from a flare, and audible emissions from a thief hatch or PRV are violations of Regulation No. 7. The Division has determined that the minimum fine for an open thief hatch, visible emissions from a flare or audible emissions from a thief hatch or PRV will be $15,000 per day. The duration of each such violation will be at least one day, unless evidence gathered by the Division and/or provided by the source proves otherwise.” (emphasis in original).

4 Key Elements
• IQR Site (Emission) Surveys• Vapor Recovery Unit, Vapor Recovery Tower and Vapor Combustor Unit Designs
• Tank Battery Evaluation & Repairs• Aftermarket Support
• 3 Phase separation – as pressure is reduced on the liquid, heavier hydrocarbon gases are released.
• Methane versus ethane, butane & propane• Higher levels of benzene & H2S• Heavier than air, so exposure to
employees and community is higher• Higher BTU, so more valuable
• 2,000 to 3,000 BTU vs. 1,000 BTU typical pipeline gas
• Sells for 2.5X normal NYMEX gas prices
• Analogy is compressing steam versus air• Heavier, wetter gas stream to compress• Liquids fall out in piping from tanks• Dew point can cause the gas to return to
liquid form at higher discharge pressures (based on compression ratios)
• H2S and CO2 (often with water vapor) cause higher levels of corrosion
• Volume of gas spikes & drops during separator dumps; and over life of battery
• Low pressure system must NEVER pull in oxygen into the pipeline

Vapor Recovery Units (NG or Electric VRU)
Vapor Recovery Towers (VRT)Vapor Combustor Units (VCU)
HY-BON / EDI’s Vent Gas Management Program is the industry’s first TOTAL SOLUTIONS APPROACH to address vented emissions from oil, condensate and tank produced water batteries.
• IQR – real design data• Best in class equipment – designed for vapor recovery, highest DRE
combustors• Engineering expertise to assist in optimum battery design to insure no
oxygen ingress (VRT) and optimum gas capture or destruction• Directed inspection and maintenance program to repair thief hatches and
relief valves• Supervision/provision of roustabout crews for installation available in some
regions• Start-up / commissioning – ongoing field and after market support / service
Bio-Filters for Oil Production Tanks and Waste Water Storage Tanks
The Bio-Filter works on the same absorption principle as the smaller plunger pump and compressor counter parts.
These filters are much larger and are filled with the same stripping agent to reduce VOC’s and GHG Emissions
Bio-Filters for Oil Production Tanks and Waste Water Storage Tanks
The Bio-Filter installed as shown here does not compromise the integrity or safety of the storage tanks.
The Bio-Filter canister can be a 4 inch thread connection ,Victaulic or Flanged connection . Installation of the filter will be installed or supervised by HY-BON personnel.
Connection
Safety
Vent gas will follow the least path of resistance and we are using this theory to flow the gas through the Bio-Filter.
In order for an applicant to claim 95% capture efficiency for a VRU the applicant must satisfy
the following basic design requirements:
• Is the VRU designed to capture vapor?• Is the compressor selected suitable for wet gas?• Is the system capable of handling swings in flow rate?• Is the system capable of handling swings in inlet pressure?• Is there sensing equipment which enables the applicant to know
that the VRU is capturing vapor(s) at peak intervals?• Can the system handle sour gas?
Vapor Recovery is NOT standard compression
• Atmospheric pressure at suction• Very wet, high BTU gas• Large variation in flow volumes
• VRUs are an acceptable method of routing of emissions back to the process. We really consider them part of the process, rather than an add-on control. If the storage vessel's potential to emit (PTE) is less than 4 tpy (and this is considering any enforceable permit the operator may have) then the tank is not subject.
From EPA
VRU's are engineered and designed for versatility,reliability and maximum run times. The VRU'sdesigns incorporate a combined 175 years of VRUexperience, resulting in rugged and proven vaporcapture.
Vapor Recovery Units (VRU’s)
Vapor Recovery Towers
Benefits:• Captures flash vapors without
contaminating the captured gas with air.
• Opportunity to maximize vapor capture, while reducing flash in storage tanks.
• Vapor Recovery Tower could potentially remove storage tanks from Quad “O” reporting.
Vapor Recovery Tower (VRT)
Pressure vessels designed to operate in excess of 30 PSIG and without emissions to the atmosphere ARE EXEMPT from Quad O Reporting
Vapor Recovery Tower
Instead of breaking out and venting from the storage tanks.

Direct Inspection & Maintenance (DI&M)
DI&M Production Facility Service
Our DI&M teams are OEM certified to repair Enardo & Jaycothief hatches and relief valves
On a program basis, we can also offer roustabout services for tank and piping repair, installation or modification
Use of the FLIR technology helps to identify issues and insure quality data.
A quality maintenance program will reduce cost and reduce emissions.
Tank Hatches• For best results, we typically set the pressure springs at 6 oz and the vacuum springs
at .4 oz– Should be set 2 to 3 ounces higher than the relief valves– Insure gasket integrity and proper sealing (Enardo / Jayco / Chinese mfgrs) – Refer to individual manufacturers recommendations
Relief Valves• For best results, we typically set at 4 ounces
– Only come with 1 oz off the shelf; must purchase the 3 ounce weights separately and install – Can be set 8 to 10 ounces depending on location– Refer to individual manufacturers recommendations
Gas Blanket• Use the cleanest, driest gas on location
– Typically off fuel gas line (preferred) or separator – Can be pulled from discharge line of VRU (past the check valve)– 1” line with regulating valve (typically 5 psig to 25 psig) with a motor valve (on/off set at
approximately 2.5 ounces – determined by location)
