The Consolidated Omnibus Budget Reconciliation Act of 1986 (COBRA) (Pub. L. 99-272, sec. 7005), codified at Section 60301 of Title 49, United States Code, authorizes the assessment and collection of user fees to fund the pipeline safety activities conducted under Chapter 601 of Title 49. COBRA requires that the Secretary of Transportation establish a schedule of fees for pipeline usage, bearing a reasonable relationship to miles of pipeline, volume-miles, revenues, or an appropriate combination thereof. In particular, the Secretary must take into account the allocation of departmental resources in establishing the schedule.[1] In accordance with COBRA, PHMSA also assesses user fees on operators of liquefied natural gas (LNG) facilities as defined in 49 CFR part 193.

On June 22, 2016, President Obama signed into law the Protecting our Infrastructure of Pipelines and Enhancing Safety Act of 2016 (Pub. L. 114-183) (PIPES Act of 2016). Section 12 of the PIPES Act of 2016 mandates PHMSA to issue regulations for underground natural gas storage facilities, impose user fees on operators of these facilities, and prescribe procedures to collect those fees. Section 2 of the PIPES Act of 2016 authorizes $8 million per year to be appropriated from those fees for each of fiscal years 2017-2019 for the newly established Underground Natural Gas Storage Facility Safety Account in the Pipeline Safety Fund. PHMSA is prohibited from collecting a user fee unless the expenditure of such fee is provided in advance in an appropriations act. If Congress appropriates funds to this account for fiscal years 2017-2019, PHMSA will collect these fees from the operators of the facilities.

According to the Energy Information Agency (EIA), there are 400 interstate and intrastate underground natural gas storage facilities currently in operation in the United States, with more than four trillion cubic feet of natural gas working capacity. EIA data is collected on form EIA-191, Field Level Storage Data (Annual), and can be accessed from the Related Links section on​naturalgas/​storagecapacity/​. Three hundred twenty-six of those facilities store natural gas in depleted hydrocarbon reservoirs, while 31 facilities store natural gas in salt caverns and 43 store it in depleted aquifers. Of the 400 underground natural gas storage facilities in the U.S., approximately half (197) are interstate facilities.

PHMSA is currently developing an Interim Final Rule (IFR) that will fulfill the requirement in Section 12 of the PIPES Act of 2016 to establish minimum Federal safety standards for underground natural gas storage facilities. The Agency expects this IFR will be issued later this year, but PHMSA has already been preparing to assume regulatory oversight of these facilities. PHMSA is designing a training program for both Federal and State inspectors to enable thorough and effective oversight of all underground storage facilities. Inspection protocols are being developed and will be made publicly available. The protocols will inform all stakeholders of PHMSA's expectations for demonstrating compliance with the minimum safety regulations. PHMSA also plans to deploy Web sites with frequently asked questions and additional guidance on the safe operation of underground natural gas storage facilities.

Once new regulations are in place, PHMSA will directly regulate interstate facilities and will provide grants to State agencies that are or become certified to regulate intrastate facilities. If no State agency is certified in a given state, PHMSA will also directly regulate any intrastate facilities. While the surface piping at underground gas storage facilities is currently subject to the 49 CFR part 192 regulations, extending Federal regulation to the wells and well bore tubing connecting the surface with the underground reservoirs is a regulatory activity not previously conducted by PHMSA that will involve substantial employment of agency resources. This will include, among other things, conducting field inspections of facility operations including reviewing operating, maintenance, integrity and emergency plans and procedures, making compliance determinations and conducting enforcement actions, and accident investigations. PHMSA estimates $2 million of the potential appropriation would fund the preparations mentioned above and direct PHMSA inspection and enforcement. The remaining $6 million of the proposed appropriation would fund grants to State agencies certified by PHMSA to regulate intrastate facilities.

PHMSA invites comments on the following proposed approach to determining the user fee assessment for underground natural gas storage facility operators. This is a tiered approach that is similar to the liquefied natural gas (LNG) plant user fee rate structure, which was modified for FY 2015 billing. The LNG user fee rate structure uses the storage capacity, in barrels of LNG, as the basis for the rate structure. The storage capacity for each operator is determined and operators are placed in tiers. Each tier represents a greater storage capacity and a higher user fee obligation. The storage capacity of an underground natural gas storage facility is referred to as the working gas capacity. PHMSA proposes to use the working gas capacity, in million standard cubic feet, for each operator, and a tiered approach to establish the underground natural gas storage facility user fee structure. The tiered approach places a larger portion of the user fee assessment on operators of larger facilities. PHMSA also considered using the number of active wells per facility as the basis for the tiers as it would also be a reasonable indicator of the expected regulatory efforts needed. PHMSA has not found a publicly available data source for the number of active wells at each facility, but may reassess the user fee rate structure in the future if this or other methods become feasible and are shown to appropriately reflect the allocation of departmental resources to these regulatory activities.

In the spring of 2017, PHMSA will use calendar year 2015 data from the Start Printed Page 78263EIA Web site to develop the underground natural gas storage facility user fee rate structure. When PHMSA promulgates regulations for operators of underground natural gas storage facilities, we plan to include the collection of annual reports to incorporate both the capacity and number of wells per facility in the annual report. If PHMSA were to collect data directly from the operators, PHMSA would discontinue the use of EIA data.

PHMSA proposes the following steps for developing the user fee rate structure. PHMSA will sum the working gas capacity for active fields for each operator. The operator working gas capacity values will be parsed into 10 tiers. The lowest values will be in tier 1 and the highest values in tier 10. The minimum and maximum Working Gas Capacities for each tier will be selected to place an equal number of operators in each tier. Each tier will have a user fee assessment to be paid by each operator in the tier. Based on a preliminary analysis of the EIA data, the tiers and assessment per tier to collect $8,000,000 would be:

TierAssessment per operatorWorking gas capacity (Mcf) range
1$12,308Less than 1,550,000.
224,615More than 1,550,000 and less than 3,500,000.
330,769More than 3,500,000 and less than 6,500,000.
436,923More than 6,500,000 and less than 11,500,000.
549,231More than 11,500,000 and less than 15,500,000.
661,538More than 15,500,000 and less than 22,000,000.
773,846More than 22,000,000 and less than 30,000,000.
880,000More than 30,000,000 and less than 50,000,000.
992,308More than 50,000,000 and less than 85,000,000.
10142,857More than 85,000,000.

If less than $8 million is appropriated to the Underground Natural Gas Storage Facility Safety Account, PHMSA will proportionally reduce the assessment for each tier to collect the appropriated amount. Regardless of the appropriated amount, PHMSA expects that 25% would fund PHMSA actions and 75% would fund grants to certified State agencies. PHMSA would continue this user fee assessment in each year funds are provided in advance in an appropriations act and these regulatory activities are carried out.
