Quad O on Storage Tanks with Safety Equipment Playing Vital Role in Reducing Tank Emissions

Vacuum & Positive Pressure Relief Prevents Leakage
Vacuum & Positive Pressure Relief Prevents Leakage
Quad O” is an abbreviation for EPA 40 Code of Federal Regulations, Part 60, Subpart OOOO. The EPA has new emissions standards defining what processes and equipment are affected, and by when. Emissions of volatile organic compounds (VOC’s) contribute to the formation of ground-level ozone, or smog. with a wide range of health concerns. Fracking (the hydraulic fracturing of shale rocks to release natural gas) set the stage for the EPA to re-examine emissions standards. The final Quad O regulation was issued on August 16, 2012, but as of January 29, 2016 changes continue to be proposed and many of the original deadlines have been extended.

Quad O applies to all onshore oil & gas facilities constructed, modified, or re-constructed after August 23, 2011.

The affected facilities include:
  • Storage vessels (tanks)
  • Hydraulically fractured well completions
  • Continuous bleed pneumatic controllers
  • Reciprocating and centrifugal compressors
  • Equipment leak detection and repair
  • SO2 sweetening units
  • Glycol dehydrators
Tanks that emit more than 6 tons of VOC’s (volatile organic compounds) per year are considered affected facilities. Per Quad O, emissions need to be reduced by 95%. Emission control devices such as closed vent systems, enclosed combustion devices, and vapor recovery units are outlined in the regulation. In addition to these, Tank Safety Equipment can help in the reduction of VOC’s. Tighter sealing pressure valves and gauges translate to lower emissions. When vapor control systems are used, Tank Safety Equipment plays an important role in providing the delivery of vapors to the system, limiting the amount of vapor release, and in protecting it through the use of arrestors.

Here are active ways you can improve your Quad O compliance by choosing these tank sealing and venting solutions:

Pressure Vacuum Relief Valves
High-performance sealing power for maximum protection against leaks and emissions.

Thief and Gauge Hatches
Ultra-tight sealing for maximum emissions control.

Emergency Relief Vents
Advanced sealing technology that exceeds the most stringent industry standards.

Flame Arrestors
Maximize safety with protection against flame propagation and detonations.

Vent Valves
The highest level of protection against leakage and emissions.
