Air Plan Approval; Minnesota; Bulk Silos FESOP Update

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Proposed rule.

SUMMARY:

The Environmental Protection Agency (EPA) is proposing to approve a site-specific revision to the Minnesota State Implementation Plan (SIP) for particulate matter less than 10 microns (PM₁₀) for the portland cement distribution terminal owned and operated by Bulk Silos, LLC (Bulk Silos), formerly known as Lafarge North America Corporation on Childs Road Terminal (Lafarge-Childs Road Terminal) located in Saint Paul, Ramsey County, Minnesota. In its June 16, 2021, submittal, the Minnesota Pollution Control Agency (MPCA) requested that EPA approve certain conditions contained in Bulk Silos' federally enforceable state operating permit (FESOP) into the Minnesota PM SIP. The request is approvable because it satisfies the requirements of the Clean Air Act (CAA). MPCA's submission included an updated modeling demonstration to show the construction changes incorporated in the Title I SIP Conditions will not interfere with the ability to maintain the National Ambient Air Quality Standards (NAAQS), as Bulk Silos' allowable PM₁₀ emissions limits will be decreased with this action.

SUPPLEMENTARY INFORMATION:

In the Final Rules section of this Federal Register , EPA is approving the State's SIP submittal as a direct final rule without prior proposal because the Agency views this as a noncontroversial submittal and anticipates no adverse comments. A detailed rationale for the approval is set forth in the direct final rule. If no relevant adverse comments are received in response to this rule, no further activity is contemplated. If EPA receives such comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed rule. EPA will not institute a second comment period. Any parties interested in commenting on this action should do so at this time. Please note that if EPA receives adverse comment on an amendment, paragraph, or section of this rule and if that provision may be severed from the remainder of the rule, EPA may adopt as final those provisions of the rule that are not the subject of an adverse comment. For additional information, see the direct final rule which is located in the Rules section of this Federal Register .
