  • Experiencing WebCMS Issues?

    Instructions for things to try before contacting WebCMS Support if you think the WebCMS is slow

  • Safer Choice Media Kit

    Safer Choice Media Kit, which provides resources such as social media outreach images and content for Safer Choice partners to use

  • User’s Guide for the Chemical Transformation Simulator (CTS)

    The CTS User’s Guide is designed to provide first-time users a complete understanding of how to utilize the CTS tool.

  • Endocrine Disruption: Human Health Research

    Endocrine disrupting chemicals can affect a range of hormonal systems in ways that interrupt multiple important systems in the body.

  • NAMs Tools Training Workshop 2024

    New Approach Methods (NAMs) Workshop planned for April 2024 in RTP, North Carolina.

  • Indoor Semi-volatile Organic Compounds (i-SVOC) Version 1.0

    i-SVOC Version 1.0 is a general-purpose software application for dynamic modeling of the emission, transport, sorption, and distribution of semi-volatile organic compounds (SVOCs) in indoor environments.

  • Assessing Chemical Process Sustainability with GREENSCOPE

    GREENSCOPE is a sustainability assessment tool used to evaluate and assist in the design of chemical processes. The goal is to minimize resource use, prevent or reduce releases, and increase the economic feasibility of a chemical process.

  • Lead-based Paint Activities Training Providers Course Information

    Links for the English and Spanish versions of the lead-based paint abatement worker model training course materials.

  • Reciprocating Compressors

    A reciprocating compressor is used to increase the pressure of natural gas in pipelines. Reciprocating compressors vent natural gas from piston rod packing systems during normal operation.

  • Storage Tanks

    Storage tanks are used to hold oil and gas condensate and operate near atmospheric pressure. Gases dissolved in the oil and condensate 'flash' out of the liquid phase. These vapors, rich in methane, may be vented to the atmosphere.

  • Pipeline Pig Launching and Receiving

    Pipeline pigging is the practice of cleaning and/or inspecting pipelines. During pigging operations, the pig is inserted into the pipeline and is forced through by pipeline pressure or by using compressed gas.

  • Fish Images to Use with Fish Advisories

    The U.S. Environmental Protection Agency developed a set of images to convey fish parts that should not be eaten to reduce possible exposure to chemicals among fish-eating populations.

  • Optimize Glycol Circulation

    During the glycol regeneration process, absorbed methane is vented at a rate directly proportional to the glycol circulation. Optimization of glycol circulation rates can reduce methane emissions at negligible cost.

  • Methanol Injection

    Replacing a glycol dehydrator with methanol injection inhibits hydrate formation and eliminates dehydrator emissions.

  • Glycol Dehydrators

    Glycol dehydrators are used to remove water from gas. The glycol absorbs water and methane when contacted with the wet gas. Glycol is then regenerated, where absorbed methane is vented to the atmosphere along with the water vapor.

  • Equipment Leaks

    Equipment leaks, commonly referred to as fugitive emissions, are characterized as unintentional emissions. Leaks occur from equipment components such as connectors, valves, open-ended lines, pressure relief valves, and storage tank thief hatches.

  • RSIG3D Local/Remote CMAQ File Reader

    RSIG3D instructions for reading local and/or remote CMAQ files

  • Engine Exhaust

    Natural gas-fired engines and turbines are used to run compressors throughout the natural gas value chain. In many operations, the natural gas stream is used to power these engines and turbines. Methane emissions result from incomplete combustion.

  • Vapor Recovery Units

    Vapor recovery units (VRUs) are commonly used to capture methane emissions from storage tanks and a variety of other low pressure sources such as pipeline pigging operations, compressors, and dehydrators.

  • Centrifugal Compressors

    A centrifugal compressor is used to increase the pressure of natural gas in pipelines. Centrifugal compressors contain rotating shafts that require seals to prevent the high-pressure natural gas from escaping the compressor casing.
