Data and Tools

This page shows all of the pages at www.epa.gov that are tagged with Data and Tools.

  • Using Quality Program Standards for Environmental Information

    The Agency uses the American National Standard ASQ/ANSI E4-2014, Specifications and Guidelines for Quality Systems for Environmental Data Collection and Environmental Technology Programs

  • E3 Sample Media Backgrounder about Supplier Efforts

    Sample document for introducing the E3 program and the Green Suppliers Network.

  • Footnotes - Recommendations of Specifications, Standards, and Ecolabels for Federal Purchasing

    This page provides footnotes to the EPA recommended standards and ecolabels for federal agencies.

  • E3 Webinar Presentations

    The E3 Support Network provided webinar presentations offering information about E3-related tools and resources.

  • Well Plugging

    A reduced emissions completion (REC) is a practice that employs equipment to capture gas produced during well completions following hydraulic fracturing and deliver it to the sales line. Compared to traditional completions, RECs reduce methane emissions.

  • Reduced Emission Well Completions and Workovers

    A reduced emissions completion (REC) is a practice that employs equipment to capture gas produced during well completions following hydraulic fracturing and deliver it to the sales line. Compared to traditional completions, RECs reduce methane emissions.

  • Pressurized Storage Tank

    Replacing an atmospheric pressure storage tank with a pressurized storage tank can significantly reduce emissions of methane and volatile organic compounds (VOCs).

  • Plunger Lift System Without Planned Atmospheric Venting

    Installing a plunger lift system is an effective method for removing accumulated liquids and restoring gas pressure. Plunger lift systems without planned venting eliminate the emissions associated with well blowdowns used to remove the accumulated liquid.

  • Pipeline Hot Taps

    Hot tapping is a procedure used to make a new pipeline connection while the pipeline remains in service, flowing natural gas under pressure. The operator can make a new connection without having to shut down the pipeline or performing pipeline blowdown.

  • Mechanical Controllers

    Replacing natural gas-powered pneumatic controllers with mechanical controllers can reduce methane emissions.

  • Flash Tank Separators

    During the dehydration process, glycol absorbs methane, volatile organic compounds (VOCs), and hazardous air pollutants (HAPs) from the wet gas. A flash tank separator can be used in the dehydration process to remove the gas absorbed by glycol.

  • Electric Glycol Circulation Pumps

    Replacing a gas-assist glycol circulation pump with an electric glycol circulation pump avoids the emissions from the assist gas.

  • Electric Compressor Motors

    Electric Compressor Motors: Installing an electric motor, in place of a gas-fired engine, can reduce methane emissions, increase operational efficiency, and reduce maintenance costs.

  • Desiccant Dehydrators

    Replacing glycol dehydrators with desiccant dehydrators that use moisture absorbing salts to remove water reduces dehydrator emissions and also results in lower operating and maintenance costs.

  • Air Starters

    Air Starters use compressed air, instead of natural gas, to start internal combustion engines for compressors, generators, and pumps. This mitigation option eliminates methane emissions from engine start-ups.

  • Advanced Methane Detection

    Advanced Methane Detection

  • Well Completions and Workovers

    Well completion is the process of bringing an oil or gas well into production. Completion steps involve casing, cementing, perforating, hydraulically fracturing in the reservoir, expelling fluids, and installing the production valve.

  • Compressor Station Blowdowns

    Compressor stations are taken offline (depressurized) for operational or maintenance needs. To take a compressor station offline, station or unit isolation valves are closed and the gas within the compressors is vented to the atmosphere (i.e., blowdown).

  • Compressor Starts

    Compressors driven by gas engines are often equipped with small gas expansion turbine motors to start the engine. These motors initiate startup of the engine with expansion of pressurized gas across the starter turbine; that gas is then vented.

  • Marginal Conventional Wells

    Well completion is the process of bringing an oil or gas well into production. Completion steps involve casing, cementing, perforating, hydraulically fracturing in the reservoir, expelling fluids, and installing the production valve.
