Prior Year - Subpart W Introduction

Introduction

Please see Reporting Form Instructions on downloading the blank reporting form and uploading the completed reporting form.
You may also refer to Optional Calculation Spreadsheet Instructions to download the Subpart W calculation spreadsheet.

All industry segments must complete the introduction worksheet.

Select the applicable industry segment for this workbook.
  • One workbook must be submitted for each industry segment.
  • If your facility is required to report emissions under more than one industry segment, a workbook should be filled out for each industry segment under which that facility falls

Fill out the general information table.
  • GHGRP ID is required.     (the GHGRP ID on the reporting form must match the facility ID in e-GGRT)
  • Reporting Year is required.    (for RY2013 this must be reported as "2013")
  • Gaseous Throughput is required.     (Do not leave this field blank.  You may report 0 (zero) throughput if this field does not apply to your facility)
  • Liquid Throughput is required.     (Do not leave this field blank.  You may report 0 (zero) throughput if this field does not apply to your facility)

Below you will find additional guidance on throughput definition for your segment:

Industry Segment

Segment-Specific Throughput Definition

Onshore Production

Gaseous Throughput:  The amount of gas produced in the basin for sales (MMscf)
Liquid Throughput:  The amount of oil (or condensate) produced in the basin for sales (thousand barrels)

Offshore Production

Gaseous Throughput:  The amount of gas produced for sales from the offshore platform (MMscf)
Liquid Throughput:  The amount of oil (or condensate) produced for sales from the offshore platform (thousand barrels)

Natural Gas Processing

Gaseous Throughput:  The amount of gas produced at the facility for sales (MMscf)
Liquid Throughput:  The amount of natural gas liquids produced at the facility for sales (thousand barrels)

Natural Gas Transmission Compression

Gaseous Throughput:  The amount of gas transported through the compressor station (MMscf)
Liquid Throughput:  Not applicable

Underground Natural Gas Storage

Gaseous Throughput:  The amount of gas injected into storage plus the amount of gas withdrawn from storage (MMscf)
Liquid Throughput:  Not applicable

LNG Import and Export

Liquid Throughput:  Not applicable

LNG Storage

Gaseous Throughput:  The amount of LNG added into storage plus the amount of LNG withdrawn from storage (MMscf)

Fill out the applicable source reporting forms for your industry segment.
  • The applicable forms are highlighted in green based upon the industry segment selected in Step 1.  You can navigate to each form using the "Go to Form" link or by using the tabs at the bottom of the workbook.
  • Source Type level emissions are reported in the gray boxes to the left of each form.  These are calculated from the data that you have entered for each source type.
  • Total emissions are reported in the last gray row of the table.  These are the sum of each gas emissions reported.
