40 CFR 62.4671 - Effective date.

The Environmental Protection Agency (EPA) is taking final action to approve a negative declaration for existing commercial and industrial solid waste incineration (CISWI) units within the State of Maryland. This negative declaration certifies that CISWI units subject to the requirements of sections 111(d) and 129 of the Clean Air Act (CAA) do not exist within the jurisdictional boundaries of the State of Maryland. EPA is accepting the negative declaration in accordance with the requirements of the CAA.

The Environmental Protection Agency (EPA) is approving a new state plan (the “plan”) submitted by the Colorado Department of Public Health and Environment (CDPHE) for the regulation of existing commercial and industrial solid waste incineration (CISWI) units within the jurisdiction of the State of Colorado. The plan has been submitted to the EPA for approval following the promulgation of federal new source performance standards (NSPS) and emission guidelines (EG) for CISWI units on March 21, 2011, and the subsequent, limited revisions to that final rule on February 7, 2013, and June 23, 2016. This plan approval final rulemaking action is being taken in accordance with sections 111(d) and 129 of the Clean Air Act (CAA, or the “Act”).

The Environmental Protection Agency (EPA) is proposing to approve a request from the New Hampshire Department of Environmental Services (NH DES) for delegation of authority to implement and enforce the Federal Plan Requirements for Sewage Sludge Incineration Units Constructed on or before October 14, 2010 (SSI Federal Plan). under Clean Air Act (CAA).

The Environmental Protection Agency (EPA) is proposing to approve revisions to the Missouri state plan for designated facilities and pollutants developed under sections 111(d) and 129 of the Clean Air Act (CAA) that were requested by Missouri Department of Natural Resources (MDNR) in two separate submissions made on August 8, 2011 and on July 3, 2014. This proposed action will amend the state regulations referenced in the state's 111(d) plan applicable to existing Hospital, Medical, Infectious Waste Incinerators (HMIWI) operating in the state of Missouri. The state rule revisions we are proposing to approve with this action update HMIWI regulatory requirements for emission limits for waste management plans, training, compliance and performance testing, monitoring, and reporting and recordkeeping to be consistent with updates to Federal rules. These regulatory revisions proposed for approval into Missouri's state plan do not impact air quality. EPA's proposed approval of this revision is being done in accordance with the requirements of CAA section 111(d) as further described in the Technical Support Document that is included in this docket.

The Environmental Protection Agency (EPA) is proposing to notify the public that it has received a negative declaration for commercial and industrial solid waste incineration (CISWI) units within the State of Maryland. This negative declaration certifies that CISWI units subject to the requirements of sections 111(d) and 129 of the Clean Air Act (CAA) do not exist within the jurisdictional boundaries of the State of Maryland. EPA is accepting the negative declaration in accordance with the requirements of the CAA.

The Environmental Protection Agency (EPA) is proposing to approve a Clean Air Act (CAA) section 111(d)/129 plan (the “plan”) submitted by the Division of Air Quality of the North Dakota Department of Health (the “Department”) on June 12, 2014. The plan would allow for the implementation of emissions guidelines for existing commercial and industrial solid waste incineration (CISWI) units within the jurisdiction of the State of North Dakota. The plan creates new enforceable emissions limits and operating procedures for existing CISWI units within the State of North Dakota in accordance with the requirements established by the revised CISWI new source performance standards (NSPS) and emission guidelines (EG), promulgated by the EPA on March 21, 2011, with subsequent final amendments to the rule promulgated on February 7, 2013. This proposed plan approval rulemaking is being taken in accordance with the requirements of sections 111(d) and 129 of the CAA and the relevant parts and subparts of the Code of Federal Regulations (CFR).

The Environmental Protection Agency (EPA) is proposing to approve a Clean Air Act (CAA) section 111(d)/129 plan (the “plan”) submitted by the Colorado Department of Public Health and Environment (CDPHE) on July 14, 2017. The plan would allow for the implementation of emissions guidelines for existing commercial and industrial solid waste incineration (CISWI) units within the jurisdiction of the State of Colorado. The plan creates new enforceable emissions limits and operating procedures for existing CISWI units within the State of Colorado in accordance with the requirements established by the revised CISWI new source performance standards (NSPS) and emission guidelines (EG), promulgated by the EPA on March 21, 2011, with subsequent final amendments to the rule promulgated on February 7, 2013. This proposed plan approval rulemaking is being taken in accordance with the requirements of sections 111(d) and 129 of the CAA and the relevant parts and subparts of the Code of Federal Regulations (CFR).

Due to adverse comments, the Environmental Protection Agency (EPA) is withdrawing the direct final rule for “State of Iowa; Approval and Promulgation of the State Implementation Plan, the 111(d) Plan, and the Operating Permits Program,” published in the Federal Register on September 15, 2017. Iowa's SIP revision included administrative changes, corrections to technical errors, revisions to titles and explanations of the scope of rules. The revision also rescinded outdated or no longer required rules for general conformity and emissions inventory relating to the Clean Air Interstate Rule (CAIR) which has been rescinded by EPA. Finally, the revision updated state rules by incorporating by reference more recent Code of Federal Regulation dates to ensure consistency between the state and Federally-approved rules.

The Environmental Protection Agency (EPA) is taking final action to approve 20 negative declarations for four designated facility classes in all Region 8 states. First, the EPA is approving negative declarations from Colorado, Montana, North Dakota, South Dakota and Wyoming for existing small municipal waste combustor (MWC) units. Second, the EPA is approving negative declarations from Colorado, Montana, North Dakota, South Dakota, Utah and Wyoming for existing large MWC units. Third, the EPA is approving negative declarations from Montana, South Dakota, Utah and Wyoming for existing commercial and industrial solid waste incineration (CISWI) units. Fourth, the EPA is approving negative declarations from Montana, North Dakota, South Dakota, Utah and Wyoming for existing other solid waste incineration (OSWI) units. Each of the negative declaration letters approved in this final rulemaking action is a certified statement from the issuing state that there are no existing designated facilities of the source category specified in the negative declaration, within the jurisdiction of that state, which would require the development of a Clean Air Act (CAA) section 111(d)/129 state plan. These approved negative declarations will serve in lieu of a state plan unless a previously unknown facility falling under these particular emissions guidelines is identified and development of a state plan becomes necessary.

The Environmental Protection Agency (EPA) is approving a request from the New Jersey Department of Environmental Protection (NJDEP) for delegation of authority to implement and enforce the Federal plan for Sewage Sludge Incineration (SSI) units. On April 29, 2016, the EPA promulgated the Federal plan for SSI units to fulfill the requirements of the Clean Air Act. The Federal plan addresses the implementation and enforcement of the emission guidelines applicable to existing SSI units located in areas not covered by an approved and currently effective state plan. The Federal plan imposes emission limits and other control requirements for existing affected SSI facilities which will reduce designated pollutants. On January 24, 2017, the NJDEP signed a Memorandum of Agreement which is intended to be the mechanism for the transfer of authority between the EPA and the NJDEP and defines the policies, responsibilities and procedures pursuant to the Federal plan for existing SSI units.

The Environmental Protection Agency (EPA) is withdrawing a direct final rule published on June 5, 2017, because one adverse comment was received during the public comment period. The withdrawn rule pertained to the EPA's receipt and approval of 20 negative declaration letters from EPA Region 8 states. These letters of negative declaration are statements by the state certifying the absence of designated facilities of a certain solid waste incinerator category or class within its jurisdiction, which obviates the statutory requirement for the state to develop a Clean Air Act (CAA) section 111(d)/129 State plan for the regulation of designated facilities of that particular category or class.

The Environmental Protection Agency (EPA) is correcting a direct final rule that appeared in the Federal Register on June 5, 2017. The document approved a total of 20 negative declarations from all EPA Region 8 states declaring an absence of existing designated facilities, of certain incinerator classes, regulated under one of the Emissions Guidelines for solid waste incineration units. An approved and promulgated negative declaration exempts a state from certain implementation plan development requirements of Clean Air Act sections 111 and 129. An error in the proposed regulatory text amending 40 CFR part 62 is identified and corrected in this action.

The Environmental Protection Agency (EPA) is proposing to approve a request from the New Jersey Department of Environmental Protection (NJDEP) for delegation of authority to implement and enforce the Federal plan for Sewage Sludge Incineration (SSI) units. On April 29, 2016 the EPA promulgated the Federal plan for SSI units to fulfill the requirements of sections 111(d)/129 of the Clean Air Act. The Federal plan addresses the implementation and enforcement of the emission guidelines applicable to existing SSI units located in areas not covered by an approved and currently effective state plan. The Federal plan imposes emission limits and other control requirements for existing affected SSI facilities which will reduce designated pollutants. On January 24, 2017, the NJDEP signed a Memorandum of Agreement which is intended to be the mechanism for the transfer of authority between the EPA and the NJDEP and defines the policies, responsibilities and procedures pursuant to the Federal plan for existing SSI units.

The Environmental Protection Agency (EPA) is approving a revised section 111(d)/129 plan submitted by the State of Maryland for existing hospital/medical/infectious waste incineration (HMIWI) units. The section 111(d)/129 plan contains revisions to a previously-approved State plan for existing HMIWI units that was submitted as a result of the October 6, 2009 promulgation of federal new source performance standards (NSPS) and emission guidelines for HMIWI units, which were subsequently amended on April 4, 2011. This action is being taken under sections 111(d) and 129 of the Clean Air Act (CAA).

This action proposes the federal plan for existing commercial and industrial incineration (CISWI) units. This proposed action implements the Environmental Protection Agency's (EPA) emission guidelines (EG) adopted on February 7, 2013, as amended on June 23, 2016, in states that do not have an approved state plan implementing the EG in place by the effective date of this federal plan. The federal plan will result in emissions reductions of certain pollutants from all affected units covered.

The Environmental Protection Agency (EPA) is proposing to approve a section 111(d)/129 plan submitted by the State of Maryland for existing hospital/medical/infectious waste incineration (HMIWI) units. The section 111(d)/129 plan contains revisions to a previously-approved state plan for existing HMIWI units and was submitted as a result of the October 6, 2009 promulgation of federal new source performance standards (NSPS) and emission guidelines for HMIWI units, which were subsequently amended on April 4, 2011. This action is being taken under sections 111(d) and 129 of the Clean Air Act (CAA).

On June 30, 2016, the Environmental Protection Agency (EPA) proposed a rule titled, “Clean Energy Incentive Program Design Details.” The EPA is extending the comment period on the proposed rule, which was scheduled to close on September 2, 2016, by 60 days until November 1, 2016. The EPA is making this change to allow for requested tribal consultation in response to the proposed rule.

On June 30, 2016, the Environmental Protection Agency (EPA) proposed a rule titled, “Clean Energy Incentive Program Design Details.” The EPA is extending the comment period on the proposed rule that was scheduled to close on August 29, 2016, by four days until September 2, 2016. The EPA is making this change to align the public comment period with the public hearing submittal time frame.

In this action, the Environmental Protection Agency (EPA) is proposing design details of the Clean Energy Incentive Program (CEIP). The CEIP is a program that states have the option to adopt if they wish to incentivize certain early emission reduction projects under the Carbon Pollution Emission Guidelines for Existing Stationary Sources: Electric Utility Generating Units (also known as the Clean Power Plan Emission Guidelines (EGs)). The framework for the CEIP was established in the Clean Power Plan EGs, where the EPA also noted that the design details of the program would be developed in a follow-on action. This proposal addresses those design details. In addition, we are re-proposing the CEIP-related aspects of the proposed rate-based and mass-based model trading rules—referred to in this action as optional example regulatory text. This proposal is consistent with the Supreme Court's orders staying the Clean Power Plan during judicial review. The timing elements of the CEIP may be adjusted, if necessary, upon resolution of the petitions for review of the Clean Power Plan.
