Environmental Protection Agency July 17, 2017 – Federal Register Recent Federal Regulation Documents

Public notice is hereby given that the state of North Dakota has revised its Public Water System Supervision (PWSS) Program by adopting federal regulations for the Revised Total Coliform Rule (RTCR) that correspond to the National Primary Drinking Water Regulations (NPDWR). The Environmental Protection Agency (EPA) has reviewed North Dakota's regulations and determined they are no less stringent than the federal regulations. The EPA is proposing to approve North Dakota's primacy revision for the RTCR. Today's approval action does not extend to public water systems in Indian country. Please see Supplementary Information, Item B.

The Environmental Protection Agency (EPA) is proposing to approve a state implementation plan (SIP) submission from Minnesota addressing the state board requirements of the Clean Air Act (CAA). EPA is also proposing to approve elements of Minnesota's submission addressing the infrastructure requirements relating to state boards for the 1997 ozone, 1997 fine particulate (PM2.5), 2006 PM2.5, 2008 lead (Pb), 2008 ozone, 2010 nitrogen dioxide (NO2), 2010 sulfur dioxide (SO2), and 2012 PM2.5 National Ambient Air Quality Standards (NAAQS). This SIP revision was submitted by the Minnesota Pollution Control Agency (MPCA) on May 26, 2016.

The Environmental Protection Agency (EPA) is approving a July 7, 2016 state implementation plan (SIP) revision submitted by the State of Maryland. The July 7, 2016 SIP submittal sought removal of a regulation in its entirety from the approved Maryland SIP which addressed Maryland's defunct Clean Air Interstate Rule (CAIR) program and sought removal from the SIP of additional provisions which referenced Maryland's CAIR program in Maryland regulations addressing general air quality definitions and the control of emissions from pulp mills in Maryland. Additionally, the July 7, 2016 SIP submittal included an amendment to a Maryland regulation regarding the use of continuous emission monitoring (CEM) systems at Kraft pulp mill boilers and combustion units in order to clarify that CEM systems must meet requirements beyond those only related to certification. The July 7, 2016 SIP submittal removing references to CAIR in Maryland's regulations satisfies Maryland's obligation pursuant to an earlier rulemaking in which EPA granted final conditional approval of Maryland's amended regulation regarding the control of emissions from Kraft pulp mills contingent upon Maryland addressing the removal of references to CAIR from its regulations and SIP. Today's action thus also converts the prior conditional approval of the pulp mill regulation to a full approval. EPA's approval of the Maryland SIP is in accordance with the requirements of the Clean Air Act (CAA) and is under CAA authority.

The Environmental Protection Agency (EPA) Region 7 announces the deletion of the Callahan property, Operable Unit 3(OU3) (Parcel ID 22U220242) of the Ellisville Superfund Site (Site) located in Wildwood, Missouri (E\1/2\, NW\1/4\, SE\1/4\, S31, T45N, R04E), from the National Priorities List (NPL). The NPL, promulgated pursuant to section 105 of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) of 1980, as amended, is an appendix of the National Oil and Hazardous Substances Pollution Contingency Plan (NCP). This partial deletion pertains to all media (soil and groundwater) of the Callahan property, (OU3) Subsite. The Bliss (OU2) and Rosalie (OU1) operable units will remain on the NPL and are not being considered for deletion as part of this action. The EPA and the State of Missouri, through the Missouri Department of Natural Resources, have determined that all appropriate response actions under CERCLA, have been completed. However, the deletion of this parcel does not preclude future actions under Superfund.
