ONRR now provides simplified UCAs for certain gas plants and geographic locations, please see the Standardized UCA page for more information.
ONRR also calculates UCAs for specific transportion systems and gas plants. See the table below for published UCAs.
Lessees transporting and processing Federal and Indian natural gas under non-arm’s-length agreements are obligated to comply with the regulations for claiming allowances for transportation and processing costs, including 30 CFR §§ 1206.157(b) and 1206.159(b) (Federal) and 30 CFR §§ 1206.178(b) and 1206.180(b) (Indian). In this case, lessees must base their transportation and processing allowance on their reasonable actual costs and may not use the values posted on this website.
Lessees transporting and processing Federal and Indian natural gas under arm’s-length agreements are obligated to comply with the regulations for claiming allowances for transportation and processing costs, including 30 CFR §§ 1206.157(a) and 1206.159(a)(Federal) and 30 CFR §§ 1206.178(a) and 1206.180(a) (Indian). When a lessee pays a bundled rate under an arm’s-length contract, the lessee must unbundle that rate in order to comply with the regulations. A lessee may use the Unbundling Cost Allocations (UCAs) posted on this website as a means of unbundling.
ONRR provides the UCAs on this website based on the best information available to ONRR at the time of publication. If ONRR receives more accurate information, then ONRR will update and modify the UCAs. You may use these UCAs as estimates for later time periods until such time as ONRR provides updated information. When ONRR updates or modifies information you may be subject to additional royalty obligations, or a credit, and associated interest under the provisions at 30 CFR §§ 1206.156(d) (for transportation allowances) and 1206.158(e) (for processing allowances). When ONRR updates the UCAs for a specific year you should adjust previously submitted royalty lines only for that specific year. Do not change previously reported data until ONRR publishes actual values. You should use the most recent UCAs as estimates for future reporting months.
