Environmental Protection Agency December 4, 2006 – Federal Register Recent Federal Regulation Documents

EPA is approving a State Implementation Plan (SIP) revision submitted by the state of Missouri for the inclusion of revisions to the Construction Permit Exemptions rule. The Construction Permit Exemptions rule lists specific construction or modification projects that are not required to obtain permits under the Construction Permits Required rule. Revisions to this rule include updating the insignificance levels, adding a new exemption for manufacturing operations (which produce insignificant emissions), clarifying the grain handling facilities exemption, and restructuring of the record keeping portion of the rule. Missouri developed the revisions to this rule under two separate state rulemaking processes.

EPA is approving a State Implementation Plan (SIP) revision submitted by the State of Missouri. This revision pertains to Grossman Iron and Steel Company's Source Registration Permit, number SR00.045A. This permit, issued by the City of St. Louis, will control particulate matter (PM10) emissions from Grossman Iron and Steel Company. This approval will make the permit Federally enforceable.

The Environmental Protection Agency, Region 8 (EPA) announces the deletion of portions of the Ellsworth Air Force Base (AFB) Site located in Meade and Pennington Counties, South Dakota, from the National Priorities List (NPL). All areas originally proposed for deletion under the Notice of Intent to Partially Delete published in the Federal Register on June 28, 2006 (71 FR 36736) are being deleted. The NPL constitutes Appendix B to the National Oil and Hazardous Substances Pollution Contingency Plan, 40 CFR Part 300, which EPA promulgated pursuant to Section 105 of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). EPA has determined, with the concurrence of the State of South Dakota through the Department of Environment and Natural Resources that the parcels pose no significant threat to public health, welfare or the environment and, therefore, no further response action pursuant to CERCLA is appropriate. This partial deletion pertains to surface soil, unsaturated subsurface soil, surface water, and sediments at Operable Units 2, 3, 4, 5, 6, 7, 8, 9, 10 and 12, and excludes the ground water medium at these parcels. The ground water medium at the Ellsworth AFB Site (OU-11, Basewide Ground Water), and the soil medium (surface and unsaturated subsurface soils) at OU-1, Fire Protection Training Area, will remain on the NPL and response activities will continue for those OUs. Two additional areas not associated with an operable unit, the Gateway Lake Ash Study Area and the Pride Hangar Study Area, are currently under investigation and are also not part of this partial deletion.
