As of 2025, the EIA-176 Form is organized into the following parts: * **Part 1:** Identification * **Part 3:** Company characteristics * **Part 4:** Natural and supplemental gas supply * **Part 5:** Liquefied natural gas (LNG) storage inventory * **Part 6:** Natural and supplemental gas disposition * **Part 7:** Comments, footnotes and continuation text lines ### Download additional documentation * [`Eia176 Blank 2011-12-31 (PDF)`](eia176/eia176_blank_2011-12-31.pdf) * [`Eia176 Blank 2015-02-28 (PDF)`](eia176/eia176_blank_2015-02-28.pdf) * [`Eia176 Blank 2017-12-31 (PDF)`](eia176/eia176_blank_2017-12-31.pdf) * [`Eia176 Blank 2021-01-31 (PDF)`](eia176/eia176_blank_2021-01-31.pdf) * [`Eia176 Blank 2024-06-30 (PDF)`](eia176/eia176_blank_2024-06-30.pdf) * [`Eia176 Blank 2027-07-31 (PDF)`](eia176/eia176_blank_2027-07-31.pdf) * [`Eia176 Instructions 2011-12-31 (PDF)`](eia176/eia176_instructions_2011-12-31.pdf) * [`Eia176 Instructions 2015-02-28 (PDF)`](eia176/eia176_instructions_2015-02-28.pdf) * [`Eia176 Instructions 2017-12-31 (PDF)`](eia176/eia176_instructions_2017-12-31.pdf) * [`Eia176 Instructions 2021-01-31 (PDF)`](eia176/eia176_instructions_2021-01-31.pdf) * [`Eia176 Instructions 2024-06-30 (PDF)`](eia176/eia176_instructions_2024-06-30.pdf) * [`Eia176 Instructions 2027-07-31 (PDF)`](eia176/eia176_instructions_2027-07-31.pdf) ### What data is available through PUDL? We are actively integrating EIA-176 data into PUDL with support from external contributors. Currently, Part 6 of the form is the only one that has been fully integrated. ### Who is required to fill out the form? According to the EIA, the Form EIA‐176 must be completed by: * Interstate natural gas pipeline companies * Intrastate natural gas pipeline companies * Natural gas distribution companies * Underground natural gas storage operators * Synthetic natural gas plant operators * Field, well, or processing plant operators that deliver natural gas directly to consumers (including their own industrial facilities) other than for lease or plant use or processing. * Field, well, or processing plant operators that transport gas to, across, or from a state border through field or gathering facilities * Liquefied natural gas (LNG) storage operators, both peaking facilities and marine terminals * Producers of high‐Btu renewable natural gas that inject into an interstate or intra‐state pipeline, or who deliver to a natural gas distributor. Data is collected annually from approximately 2,000 respondents, with a March 1st filing deadline. Each operator must file **one report per state** in which they are doing any of the following activities: * Gas (natural, commingled natural and supplemental gas, or LNG) transportation using respondent‐operated facilities other than field or gathering lines * Gas transportation to, from, or across a state border using respondent‐operated field or gathering lines * Gas delivery directly to consumers using respondent‐operated facilities other than field, well, or plant operators delivering solely for lease and plant use or processing * Gas storage in respondent‐operated underground storage reservoirs, or LNG storage facilities * Synthetic natural gas production in respondent‐operated facilities Subsidiary companies are required to file separate reports if they meet these filing requirements, but can specifically request permission from the EIA to consolidate filing. ### What does the original data look like? We archive EIA-176 data from two sources: CSV files that are exported from the [EIA Natural Gas Query System](https://www.eia.gov/naturalgas/ngqs) by iterating through all predefined reports related to Form 176, as well as a custom report that includes every numerical series related to Form 176. We also archive but do not currently process the bulk CSV download of all available natural gas data, since it is less well structured than the exports from the Natural Gas Query System. ## Notable Irregularities * **Offshore gas reporting:** For the purposes of Form 176 filings, a state is defined as including adjacent offshore Federal Domain areas. This means that any offshore gas operations will be reported under the relevant state. * **Adjustment companies:** The original company-level data contains a number of “adjustment companies” that do not appear to be documented in the Natural Gas Query System [user guide](https://www.eia.gov/naturalgas/ngqs/ngqs_user_guide.pdf). These companies all have “adjustment company” in their name and IDs beginning with 176999. These records are included in the company-level data where they report values. ## PUDL Data Transformations To see the transformations applied to the data in each table, you can read the docstrings for [`pudl.transform.eia176`](../autoapi/pudl/transform/eia176/index.md#module-pudl.transform.eia176) created for each table’s respective transform function. ### Validating and dropping duplicated data The original data includes aggregated data at the U.S. and state-wide scale, which we validate against the company-level data but do not publish to avoid data duplication. Similarly, the original data includes totals fields (e.g., sales totals) that are sums of other fields and are calculated by the EIA, not directly reported by companies filling out the form. We validate these totals fields against their components and drop them during transformation to avoid duplicating values during aggregation.
