II. Background Phosphogypsum is the waste byproduct of wet acid phosphorous production. It contains elevated concentrations of the radionuclide radium, which decays to form radon gas. The EPA’s regulations under the Clean Air Act at 40 CFR part 61, subpart R (hereafter ‘‘Subpart R’’) require that phosphogypsum must be disposed of in engineered piles, called stacks, to limit public exposure to its radioactive components. Subpart R allows the removal of phosphogypsum from stacks for outdoor agricultural purposes and indoor research and development, subject to conditions and restrictions. Any other use of phosphogypsum requires prior approval from the EPA. The EPA may approve a request for a specific use of phosphogypsum if it determines that the proposed use is at least as protective of public health as placement of phosphogypsum in a stack. The processes for requesting such an approval are described in 40 CFR 61.206. Mosaic Fertilizer, LLC submitted a request for a Small-scale Road Pilot Project on Private Land in Florida in March 2022, and submitted a Revised PO 00000 Frm 00067 Fmt 4703 Sfmt 4703 88763 Request for Approval of Use of Phosphogypsum in Small-scale Pilot Project in August 2023. Mosaic has proposed to construct a small-scale pilot project at its New Wales facility in Polk County, Florida. Mosaic’s plan is to construct four sections of test road having varying mixtures of phosphogypsum (PG) in the road base ‘‘to demonstrate the range of PG road construction designs that meet the Florida Standard Specifications for Road and Bridge construction.’’ The pilot project will be constructed in the place of an existing facility road near the phosphogypsum stack, and the study will be conducted in conjunction with researchers from the University of Florida. The EPA has performed a complete review of Mosaic’s request, documented in Review of the Small-scale Road Pilot Project on Private Land in Florida Submitted by Mosaic Fertilizer, LLC. The Agency’s review found that Mosaic’s request is complete per the requirements of 40 CFR 61.206(b). Further, the review found that Mosaic’s risk assessment is technically acceptable, and that the potential radiological risks from the proposed project meet the regulatory requirements of 40 CFR 61.206(c); that is, the project is at least as protective of public health as maintaining the phosphogypsum in a stack. Therefore, the Agency has issued a pending approval of the small-scale pilot project per 40 CFR 61.206. The pending approval and all supporting documentation are available via the regulations.gov website (www.regulations.gov; Docket ID: EPA– HQ–OAR–2024–0446). This approval initially was pending a 30-day public comment period; with today’s notice, the Agency is extending the comment period by an additional 15 days. Approval by the Agency is specific to the pilot project as described in the Mosaic request and indicates only that this project meets the approval requirements of Subpart R. III. Request for Comments The Agency is continuing to solicit public comment on its pending approval until November 23, 2024. Upon receipt of public comments, the EPA will review them for relevance to the pending design and determine if they contain information that would lead to a concern for human health or environmental impacts not previously considered. Comments must be specific to the small-scale pilot project as it is described in Mosaic’s request and the EPA’s pending approval.

II. Background

    Phosphogypsum is the waste byproduct of wet acid phosphorous 
production. It contains elevated concentrations of the radionuclide 
radium, which decays to form radon gas. The EPA's regulations under the 
Clean Air Act at 40 CFR part 61, subpart R (hereafter ``Subpart R'') 
require that phosphogypsum must be disposed of in engineered piles, 
called stacks, to limit public exposure to its radioactive components. 
Subpart R allows the removal of phosphogypsum from stacks for outdoor 
agricultural purposes and indoor research and development, subject to 
conditions and restrictions. Any other use of phosphogypsum requires 
prior approval from the EPA. The EPA may approve a request for a 
specific use of phosphogypsum if it determines that the proposed use is 
at least as protective of public health as placement of phosphogypsum 
in a stack. The processes for requesting such an approval are described 
in 40 CFR 61.206.
    Mosaic Fertilizer, LLC submitted a request for a Small-scale Road 
Pilot Project on Private Land in Florida in March 2022, and submitted a 
Revised Request for Approval of Use of Phosphogypsum in Small-scale 
Pilot Project in August 2023. Mosaic has proposed to construct a small-
scale pilot project at its New Wales facility in Polk County, Florida. 
Mosaic's plan is to construct four sections of test road having varying 
mixtures of phosphogypsum (PG) in the road base ``to demonstrate the 
range of PG road construction designs that meet the Florida Standard 
Specifications for Road and Bridge construction.'' The pilot project 
will be constructed in the place of an existing facility road near the 
phosphogypsum stack, and the study will be conducted in conjunction 
with researchers from the University of Florida.
    The EPA has performed a complete review of Mosaic's request, 
documented in Review of the Small-scale Road Pilot Project on Private 
Land in Florida Submitted by Mosaic Fertilizer, LLC. The Agency's 
review found that Mosaic's request is complete per the requirements of 
40 CFR 61.206(b). Further, the review found that Mosaic's risk 
assessment is technically acceptable, and that the potential 
radiological risks from the proposed project meet the regulatory 
requirements of 40 CFR 61.206(c); that is, the project is at least as 
protective of public health as maintaining the phosphogypsum in a 
stack. Therefore, the Agency has issued a pending approval of the 
small-scale pilot project per 40 CFR 61.206. The pending approval and 
all supporting documentation are available via the regulations.gov 
website (www.regulations.gov; Docket ID: EPA-HQ-OAR-2024-0446). This 
approval initially was pending a 30-day public comment period; with 
today's notice, the Agency is extending the comment period by an 
additional 15 days. Approval by the Agency is specific to the pilot 
project as described in the Mosaic request and indicates only that this 
project meets the approval requirements of Subpart R.

III. Request for Comments

    The Agency is continuing to solicit public comment on its pending 
approval until November 23, 2024. Upon receipt of public comments, the 
EPA will review them for relevance to the pending design and determine 
if they contain information that would lead to a concern for human 
health or environmental impacts not previously considered. Comments 
must be specific to the small-scale pilot project as it is described in 
Mosaic's request and the EPA's pending approval. Should the EPA receive 
significant adverse comments on aspects of this specific

[[Page 88764]]

pilot project, the Agency will give the applicant the opportunity to 
amend the analysis or request. If the comments can be successfully 
addressed, the EPA will publish a response to comments and notify the 
public. The Agency's decision to approve or deny a request for other 
use under 40 CFR 61.206 is not a rulemaking. The EPA's complete process 
of soliciting and addressing comments is described in Section 2.4 of 
Applying to EPA for Approval of Other Uses of Phosphogypsum: Preparing 
and Submitting a Complete Petition Under 40 CFR 61.206, A Workbook.
    Electronic copies of the application, the EPA's review, and 
relevant background materials are available in the public docket \1\ 
and on the EPA phosphogypsum website.\2\ Physical copies of the Mosaic 
request and the Agency's technical evaluation have been placed for
