ENVIRONMENTAL PROTECTION AGENCY

A. JUSTIFICATION

1. IDENTIFICATION OF INFORMATION COLLECTION

a) Title: NESHAP for Radionuclides (40 CFR part 61, subparts B, K, R and W) (Renewal)

EPA Number 1100.15 OMB Control Number 2060-0191

b) Short Characterization

On December 15, 1989, pursuant to Section 112 of the Clean Air Act as amended in 1977 (42 USC 1857), the EPA promulgated NESHAPs to control radionuclide emissions from several source categories. The regulations were published in 54 FR 51653, and are codified at 40 CFR Part 61 subparts B, K, R, and W, and impose the following radionuclide dose and emission standards:

Subpart B--Underground Uranium Mines ‑ 10 mrem/yr

Subpart K--Elemental Phosphorous Plants ‑ 2 curies/yr

Subpart R--Phosphogypsum Stacks ‑ 20 pCi/m²‑s

Subpart W--Uranium Mill Tailings ‑ 20 pCi/m²‑s

Originally there were seven subparts B, H, I, K, R, T and W--that were published in the December 15, 1989 Federal Register (54 FR 51653). Since the 1989 notice, subparts I and T are no longer regulated by EPA. Due to petitions for reconsideration, EPA rescinded subpart T as it applies to owners and operators or uranium mill tailings disposal sites licensed by NRC or an affected Agreement State on July 15, 1994, 59 FR 36280. Subpart I as it applies to NRC-licensed facilities was rescinded on December 30, 1996 (61 FR 68971) because in the 1990 Clean Air Act amendments, Congress directed EPA to stop regulating radionuclide emissions from NRC licensed facilities if EPA determines that the NRC regulatory program protects the public health with an ample margin of safety. After careful review, EPA determined that public health would be protected with an ample margin of safety by NRC’s program. Subpart H does not require an ICR because it covers Federal facilities, which are not subject to the Paperwork Reduction Act. The existing subpart I of the radionuclide NESHAP now only applies to non-DOE federal facilities not licensed by NRC. The non-DOE federal facilities not licensed by NRC, namely, DoD facilities, are expected to have emissions below 1% of the standards and are therefore not subject to the reporting requirements.

Information collected is used by EPA to ensure that public health continues to be protected from the hazards of airborne radionuclides by compliance with these standards. If the information were not collected, it is unlikely that a violation of these standards would be identified and, thus, there would be no corrective action initiated to bring the facilities back into compliance. Compliance is demonstrated through emission testing and/or dose calculation. All facilities are required to calculate, monitor, and maintain their records for 5 years. The rationale for the 5 year record keeping requirement is from 40 CFR part 61, Section 61.95. In some cases, they also report their results to EPA.

2. NEED FOR AND USE OF THE COLLECTION

(a) Need/Authority for the Collection

In the context of the Clean Air Act (42 USC 1857), Section 114 authorizes the Administrator of EPA to require any person who owns or operates any emission source or who is subject to any requirements of the Act to:

- Establish and maintain records

- Make reports, install, use, and maintain monitoring equipment or method

- Sample emissions in accordance with EPA‑prescribed locations, intervals and methods

- Provide information as may be requested

(b) Practical Utility/Users

EPA’s regional offices use the information collected to ensure that public health continues to be protected from the hazards of radionuclides by compliance with health based standards.

EPA's compliance monitoring activities vary widely. EPA could issue a letter requesting information about compliance or could conduct a full­ scale investigation, including on‑site inspections.

When EPA first learns of a compliance problem, EPA attempts to remedy the problem by holding informal discussions with the owner/operator of the source. If it is not possible to remedy the problem informally, formal action is taken. EPA's Clean Air Act Compliance Enforcement Guidance Manual identifies the Agency's informal and formal enforcement operating procedures.

3. NON-DUPLICATION, CONSULTATIONS AND OTHER COLLECTION CRITERIA

(a) Non-duplication

In accordance with 40 CFR Part 61, the specific information requested by this notice is not currently collected by any other office within EPA or any other governmental agency.

(b) Public Notice Required Prior to ICR Submission to OMB

On July 31, 2015 (80 FR 45655), EPA requested comments on specific aspects of this ICR, with a 60 day comment period which closed on September 30, 2015. EPA received one comment.

(c) Consultations

In developing the regulations, EPA gathered extensive background information on the affected facilities. In addition to background information collected from the regulated sources, public comments were received during the rulemaking process and they are contained in the public docket. Since the rules were promulgated, there have been opportunities for dialogue between EPA and affected facilities which have resulted in changes to the rules, memorandums of understanding, and rescissions. EPA contacted Air Division and/or Radiation Protection staff in all EPA Regions to obtain latest tally for the number of facilities subjected to the reporting requirements. In the preparation of the 2015 ICR, EPA contacted NRC and assumes that the information obtained then is still current. As a result of these consultations and the provision in the Clean Air Act Amendments, EPA was able to eliminate duplication of effort between EPA and NRC in instances where EPA determined that the NRC program could provide protection of the public health with an ample margin of safety.

(d) Effects of Less Frequent Collection

All reporting is annually or less frequent than annually.

(e) General Guidelines

This ICR meets OMB’s collection guidelines, the Agency received one comment during the comment period which ended September 30, 2015, and does not duplicate another collection.

(f) Confidentiality

This section does not apply because this ICR does not request information of confidential nature.

(g) Sensitive Questions

This section is not applicable because this ICR does not request sensitive information.

d. prepare and submit the report to EPA.

For record keeping requirements, all facilities are required to calculate, monitor, and maintain their records for five years and upon request be made available for inspection by the Administrator, or his/her authorized representative. (See Table W)

Record Keeping

The record keeping requirements of each subpart are similar and have been summarized in the paragraph below.

The owner or operator of the facility must maintain records documenting the source of input parameters including the results of all measurements upon which they are based, the calculations and/or analytical methods used to derive values for input parameters, and the procedure used to determine compliance. This documentation should be sufficient to allow an independent auditor to verify the accuracy of the determination made concerning the facility's compliance with the standard. These records must be kept at the mill or facility for at least five years and, upon request, be made available for inspection by the Administrator, or his/her authorized representative.

5. THE INFORMATION COLLECTED ‑‑ AGENCY ACTIVITIES, COLLECTION METHODOLOGY, AND INFORMATION MANAGEMENT

(a) Agency Activities

Information being collected is pursuant to Federal regulation. Agency activities consist of reviewing owner or operator test reports and maintaining files. EPA contacted all ten EPA Regional Offices to get the total number of mining facilities subjected to NESHAPs monitoring and reporting requirements at 40 CFR Part 61, Subparts B, K R and W. The total number of facilities has increased from 47 to 52 between 2012 and 2015. There are two Subpart B, one Subpart K, 45 Subpart R and four Subpart W facilities subjected to the reporting requirements.

(b) Collection Methodology and Management

The Office of Radiation and Indoor Air and the EPA regional offices have planned and allocated resources for the efficient and effective management and use of this information.

Records must be maintained documenting the source of input parameters including the results of all measurements upon which they are based, the calculations and/or analytical methods used to derive values for input parameters, and the procedure used to determine effective dose equivalent. This documentation should be sufficient to allow an independent auditor to verify the accuracy of the determination made concerning the facility's compliance with the standard. These records must be kept at the site of the facility for at least five years and, upon request, be made available for inspection by the Administrator, or the Administrator’s authorized representative.

The Agency has determined that the annual report review and periodic on site inspection is the most effective method to insure compliance. EPA regional office staff review facility annual reports to determine if compliance with the regulatory standards are being maintained. Verification of data is accomplished by recalculation of dose using computer models and conducting site inspections or witnessing an emission test.

(c) Small Entity Flexibility

None of the regulations covered by this ICR are applicable to small entities.

(d) Collection Schedule

For some subparts, annual reports are required to provide yearly certification of compliance with a health based standard; therefore, less frequent reporting was not considered an option to reduce burden because of the yearly stipulation in the rule. However, for other subparts (such as subpart R), it was determined during rulemaking that less frequent reports were adequate to protect public health.

6. ESTIMATING THE BURDEN AND COST OF THE COLLECTION

Burden and costs estimates have been calculated separately for each subpart. Respondent labor rates are based on ‘mean’ values from the 2014 data of the US Department of Labor, Bureau of Labor Statistics (BLS) for the mining industrial sector. These national industry-specific occupational employment and wage estimates are calculated with data collected from employers of all sizes, in metropolitan and non-metropolitan areas in every State and the District of Columbia, in NAICS 212200 - Mining (except Oil and Gas) and NAICS 325100 – Basic Chemical Manufacturing. The hourly rates for three labor categories reported for the above two NAICS codes were obtained from the 2014 Occupational Employment Statistics published by the Bureau of Labor Statistics (BLS). The reported rates were adjusted for overhead costs by multiplying with a factor of 1.5 to estimate the loaded hourly labor rate. This loaded hourly labor rate for 2014 then was increased by 1% to account for inflation from 2014 to 2015. The labor key is as follows: Management (Mgmt) ($104/hr); Technical (Tech) was based on the mean salary for “all production operations” ($62/hr) in the mining sector which includes mining engineers, environmental engineers and geologists. Clerical (Cler) ($27/hr) was based on the hourly labor rates for secretary and information clerk in the mining sector in the 2014 BLS data.

The tables representing each subpart are listed below with their reporting requirement information. (Note: Subpart R has 2 tables; Table 1 represents the 14 stacks required to complete a one-time report and Table 2 represents the 10 stacks that potentially have to conduct radon flux testing every year if phosphogypsum is removed from the stacks.)

B -- Underground Uranium Mines

In order to complete Subpart B reporting requirements respondents will:

1. read and understand the regulatory provision,

2. perform radon-222 emission measurements as required in 40 CFR part 61, Appendix B, Method 115,

3. perform data analysis including Method 115 source term calculations and dose calculation using an approved model for concentration calculations,

4. prepare and submit report.

- The estimated capital/start-up cost includes the monitoring equipment needed to perform Method 115 testing for one mine.

- Capital/start-up burden includes understanding regulatory provisions and installation of equipment for emission testing.

- Estimated annual costs related to testing include calibration, and repairs costs.

- Estimated annual burden hours collecting emission data from monitoring equipment and performing data analysis and calculations, report preparation and data management.

- Based on reports received during the current reporting period, only two mines at this time are mechanically venting and required to submit a report.

- It is estimated that the testing materials for 300 flux measurements and the analysis is obtained from a contract source at a cost of $37/measurement.

- It is estimated that it will take four days for two people to place, collect and ship 300 samples to a testing lab.

- It is estimated that out of 45 stacks, those that have not closed yet (14) may require to complete this one-time report.

- It is estimated that 10 phosphogypsum stacks may have to conduct radon flux testing every year if phosphogypsum is removed from the stack. For these stacks, the radium-226 concentration must also be determined and included in certification papers. Radon flux measurements for these sites will be as discussed above. Section 61.207 requires a minimum of 30 samples from each area where phosphogypsum is being removed from the stack. Additional sampling is required where the concentrations approach 10 pCi/g Ra-226. Therefore, we conservatively estimate that 100 samples per stack will be necessary to document radium-226 concentrations and that radium analysis will be at $100 per sample from a contract source. It is estimated that it will take two people three days to collect, prepare and ship the samples.

W--Uranium Mill Tailings

In order to complete these reporting requirements respondents will:

a. read and understand the regulatory provision,

b. perform radon flux testing required in 40 CFR part 61, Appendix B, Method 115,

c. perform data analysis including Method 115 radon flux calculations,

d. prepare and submit the report to EPA.

- It is estimated that the testing materials for 300 measurements and the analysis is obtained from a contract source at a cost of $37/measurement.

- It is estimated that it will take one day for two people to place 300 canisters and one for two people to collect the canisters and ship them to a testing lab.

- It is estimated that 4 facilities will file a report annually.

- The estimated cost for a contractor to complete the testing is $2,834.

* Assumes that the potential for all operational stacks to close and then potentially remove Ra-226. This is a conservative assumption, as only one stack currently removes Ra-226 for agricultural use.

Average annual burden per response: 3,778/21 = 179.9. For capital with a 20-year life, and assuming 5% discount rate, the annualized cost is 8.02% of the capital cost.

Total Annualized capital/start up cost: $0 x 8.02% = $0

Total Annualized Capital and O&M Costs: $0+ $320,600 = $320,600.

ESTIMATED AGENCY BURDEN AND COST

The burden to the EPA is only for reviewing the reports submitted by the regulated community to ensure that emissions and dose are within the limits set by the regulations. The main burden is on the regulated community as they have to monitor emissions, compile the data, and submit the necessary reports for compliance purposes. The estimated agency burden and costs are as shown in the table below. Agency salaries were found in 2015 General Schedule Salary Table. The data for review of reports for compliance was based on the salary scale for GS-13, step 5 (Tech), with a multiplier of 1.5 to include overhead; this resulted in $60/hr. For the Clerical category, the salary scale for a GS-9, step 5 (Cler) was used with a multiplier of 1.6 to account for overhead; this resulted in $35/hr.

Burden Statement: The annual public reporting and record keeping burden for this collection of information is estimated to average 180 hours per response. Burden means the total time, effort, or financial resources expended by persons to generate, maintain, retain, or disclose or provide information to or for a Federal agency. This includes the time needed to review instructions; develop, acquire, install, and utilize technology and systems for the purposes of collecting, validating, and verifying information, processing and maintaining information, and disclosing and providing information; adjust the existing ways to comply with any previously applicable instructions and requirements; train personnel to be able to respond to a collection of information; search data sources; complete and review the collection of information; and transmit or otherwise disclose the information. An agency may not conduct or sponsor, and a person is not required to respond to, a collection of information unless it displays a currently valid OMB control number. The OMB control numbers for EPA's regulations are listed in 40 CFR part 9 and 48 CFR chapter 15.
