Methane Emissions

The following information is a high level description of EQT's current Methane Monitoring and Repair Program as of May 1, 2018. EQT recently joined ONE Future in an effort to expand our knowledge as we continuously work to improve the efficiency of the natural gas supply chain by evaluating and establishing methane emission reduction targets that are most appropriate for our business operations. We believe that such targets should be meaningful to our investors and other stakeholders, as well as align with EQT's long-term strategy. More comprehensive disclosure regarding methane emissions will be included in our 2018 Corporate Social Responsibility report, which will utilize year-end 2017 data.

Methane Intensity Rate 
In 2016, EQT reported total methane emissions of 27,300 tons. Production operations had a methane intensity of 4.8 mtons/Bcfe; and Midstream operations (gathering+ transmission) had a methane intensity of 14 mtons/Tbtu. 

Venting/Flaring Practices 
In an effort to reduce the volume of flared-gas, EQT has been using a green completions program since 2015. During 2017, green completions technology was utilized for 100% of the wells that were completed. Green completions technology transfers the natural gas at the wellhead to a separator immediately after well completion, as opposed to flaring or venting the gas. 

In order to minimize flaring at condensate wells, we design closed-vent systems with lowpressure separators and vapor recovery systems. These systems use vapor destruction on the storage vessels. 

LDAR Program Descriptions 
EQT's facilities operate in compliance with federal methane standards, as well as with each state's respective permit requirements. Our primary operations are located in Pennsylvania, Ohio, and West Virginia, where there are robust air emission regulations that cover the oil and gas sector. EQT performs leak detection and repair (LDAR) surveys utilizing optical gas imaging (OGI) technology on a significant number of wells and compressor stations. Dependent upon the facility, the frequency of these LDAR tests can range from monthly to annually;and OGI monitoring is currently performed on more than 30% of our compressor stations and dehydration facilities [1] and 65% of our unconventional wellpads [2]. EQT monitors emissions on per-facility or per-asset basis, as opposed to a well-by-well basis. For example, if there are 10 wells on a single wellpad, EQT monitors and reports emissions for the well pad in its entirety, which is all the wells and associated equipment. Beginning in 2018, EQT will perform OGI monitoring on every unconventional wellpad pursuant to standards established by the Center for Responsible Shale Development. 

As an additional LDAR measure on our unconventional wells, EQT has remote gas detection monitors inside the gas processing units that monitor for leaks in real-time. If a leak is detected, an alert is sent to EQT's gas control center, which then assigns a specialist to conduct an inspection and any confirmed leak is repaired as soon as practical. For our conventional wells, we perform auditory, visual, and olfactory inspections on a quarterly basis. 

Leak Repair Procedures 
Unless deemed an emergency or hazardous situation, our standard practice is to repair all minor leaks Immediately or within 15 days. EQT uses a management system to track leak repairs along its various pipelines and Is upgrading its management system to track leak repairs at its wellpads. EQT's standard practice exceeds voluntary, state, and federal requirements related to leak repair procedures.

If a leak is found at a midstream facility, a work order for that leak is created and assigned to the facility supervisor who coordinates activities for the repair. If the repair is not completed within three days, an alert is sent out through the management system. EQT's production operations strive to repair leaks immediately; however, if a leak cannot be immediately repaired, due to lack of proper tools or knowledge, the site supervisor is notified and a specialist is assigned to repair the leak. In both the midstream and production operations, all leak repairs are re-surveyed.

In 2017, more than 90% of all leaks detected in production operations were repaired Immediately. During 2016 and 2017, there were no repairs delayed beyond the applicable regulatory limits. Again, if safety is an issue, repairs are completed as quickly as possible. 

Leak Detection Training
A small team of EQT employees have been trained by optical gas imaging experts and certified to operate FLIR or OpGal optical gas imaging cameras. The training consists of a three-day course that includes both classroom and onsite experience. The course objectives are to explain the regulatory framework for OGI, demonstrate proper operation of the cameras, explain the basics of thermal science, and illustrate the nuances of using the specialized technology. EQT currently has nine employees who have been trained and certified in optical gas imaging, and we plan to train additional employees during 2018. 

EQT uses OpGal EyeCGas OGI, FLIR GF320 OGI, and FLIR GFx320 OGI cameras. Each of these cameras has been verified by its manufacturer to meet the Environmental Protection Agency's (EPA} LDAR requirements under the EPA's New Source Performance Standards for the Oil and Natural Gas Industry. 

High-Bleed Controller Replacement
In 2016, EQT commenced a high-bleed controller replacement program and replaced 515 pneumatic devices with intermittent-bleed or low-bleed controllers. As of Q1 2018, we are operating four high-bleed pneumatic controllers, which represents less than 0.04% of our total natural gas pneumatic controller count. Going forward, our new compressor stations will be designed to utilize air compression in lieu of natural gas controllers; and all new wellpads will use intermittent-, low-, or no-bleed pneumatic controllers.
