early 2000's, the American Petroleum Institute (API) has supported the SANGEA™
software tool for petroleum, natural gas and petrochemical companies to
quantify greenhouse gas (GHG) emissions and to standardize emissions
reporting. Regulatory changes, including mandatory reporting requirements for
GHG emissions globally, prompted API to sponsor a major overhaul of the
software including current calculation methodologies. As announced in the
Summer 2013 issue of Environmental Quarterly, API chose Trinity
Consultants to develop its SANGEA™-4 software, with version 4.1 released in
2013. SANGEA™ 4.2, the newest release, addresses U.S. EPA's reporting
changes to the Mandatory Reporting Rule (MRR), Subpart W for Reporting Year
(RY) 2015 and refines reporting functions for the API Compendium.
SANGEA™-4 is a desktop database program with
a user-friendly interface that can be used to manage various types of
emission sources throughout a large entity for corporate performance
and/or regulatory reporting requirements. In order to build a solution
that would promote long-term software usability and easy maintenance, the
new product replaces a spreadsheet-based application to a Web-based product
developed with a Microsoft .NET framework and Access database files for
source information storage.
SANGEA™-4 provides calculation
methodologies in various modules based on API's Compendium 2009 and U.S.
EPA's MRR for GHG emissions, Subparts C, P, W, and Y. The software
includes emission factors for criteria pollutants, as well, which enables
users to quantify emissions for both GHG and criteria pollutants in one
tool. SANGEA™-4 also can be used to track energy consumption and
normalize emissions on a production basis (e.g., ton GHG/bbl of product).
The information from SANGEA™-4 is used for API GHG benchmarking studies
and to comply with Federal GHG emission mandatory reporting rules for
the petroleum and aligned industries.
U.S. EPA MRR Subpart W
On February 4, 2016, U.S. EPA released the Reporting
Year (RY) 2015 GHG emission reporting form for Subpart W. The RY 2015
reporting incorporates significant changes from the RY 2014 report, including
new data element reporting requirements that are not explicitly clear after the
changes to the mandatory reporting rule. A summary of key GHG emission
reporting requirements that are incorporated in SANGEA™ 4.2 is provided as
- Refined the reporting of local specified fuels
- Revised calculation methodology's 2 and 3 data input windows for Liquid
- Corrected the dump valve emission calculation in Storage
Tank per the Subpart W rule revision
- Refined the data input interface
for well testing venting
- Revised Subpart W reports for Equipment
- Updated the Subpart W report format
Since the release of SANGEA 4.1, we have collected
feedback from international users and made a few updates to refine the
- Refined the fuel composition exporting
- Added an aggregated API report function
- Updated a
few source set up interfaces to provide clearer instructions
SANGEA™-4 Reporting Hierarchy
The reporting entity hierarchy is
retained in SANGEA™ 4.2 including the reporting entity, location group,
location, and source set up process, with extended steps to incorporate more
source-specific requirements under multiple protocols. Sources are configured
for a specific location. Multiple locations/location groups can be created
under one SANGEA™ 4.2 working file (i.e., a Microsoft Access database file),
which allows companies to report emissions by business operation groups,
geographical regions, or regulatory reporting entities. The figure below
provides a typical reporting entity hierarchy structure that can be established
in SANGEA™ 4.2.
SANGEA 4.2 Reporting Entity Hierarchy
SANGEA™-4 Emission Source Modules and Functions
integrates two GHG reporting protocols with numerous source types. The table
below shows the available source "modules". Within each module, wizards
help users set up emission sources and multiple calculation methods for the
protocols. The software guides users to specify source parameters that are
needed for GHG emissions calculation and/or reporting requirements. These
source parameters are stored in the source database for future emission
inventory reports. SANGEA™ 4.2 also offers a "User Defined Sources" module
under the API Compendium 2009 that allows users to define sources that are
not already established in SANGEA™ 4.2.
of Source Modules in SANGEA 4.2
defined sources allow users to create source types not covered under the
There are many user-friendly editing functions included in
SANGEA™ 4.2 that allow users to create, delete and edit sources quickly, such
as the following:
- Gas composition property and API gravity
calculations are included.
- Source import and export tools for
Stationary Combustion - allowing users to edit a large number of combustion
sources in Excel spreadsheets then import into SANGEA™ 4.2. Source
parameters can also be exported to spreadsheets that can be used in other
applications such as EPA's MRR reporting tools.
- For each new
reporting year, users can copy from an existing report file - this function
copies all source parameters from the existing file and removes all
activity data that should be updated for the new reporting year.
- Default emission factors are automatically selected for specific fuels
or sources and can be checked for reference at the "Tools" menu.
- "Subpart W Reporting Requirement by Industry Segment" is listed for
easier reference for applicable emission sources.
4.2 is available from API for organizations in the petroleum and other
applicable industries. Upon the original release of SANGEA 4, Ms.
Adefemi, Senior Statistical Analyst at API, stated that, "The
objective of sponsoring SANGEA™-4 is to provide a user-friendly reporting
tool to the Oil & Gas industry and to encourage consistent reporting
of GHG emissions. API sponsors an annual survey on GHG emissions and
criteria pollutants. SANGEA™-4 will assist the industry in recording and
benchmarking consistent and comparable data, and also in analyzing the
environmental footprint." Many oil and gas companies in the US and
abroad have adopted SANGEA™-4 for corporate GHG reporting requirements. To

SANGEA™-4 development is led by T3, a division of Trinity Consultants that
implements EH&S information management solutions (EMIS), with commercial
software development expertise from the BREEZE software group. T3 has almost
20 years of experience developing custom software and implementing EMIS
solutions in a myriad of industries. For more information about SANGEA™ 4.2
