To address consistency with U.S. EPA regarding particulate matter with an aerodynamic diameter less than or equal to 2.5 micrometers (PM2.5), the Department is proposing rule changes in three areas:
(A) Section 404.05 to add the Class I, Class II, and Class III increment values to ch. NR 404 as established in 40 CFR 51.166 (c); (B) Section 405.02 (3), (21m), and (22m), to include PM2.5 in the definitions of “baseline area”, “major source baseline date”, and “minor source baseline date”, consistent with federal regulations in 40 CFR 51.166 (b); and To address consistency with U. S. EPA regarding the definition of VOC, the Department proposes to add eight compounds to the list of excluded compounds in the state definition in s. NR 400.02 (162), Wis. Adm. Code. This is consistent with the federal definition of VOC in 40 CFR 51.100 (s). 7. Comparison with similar rules in adjacent states (Illinois, Iowa, Michigan and Minnesota):
This proposed rule implements changes needed to assure consistency between state and federal rules and thus, result in rules similar to those in neighboring states. Illinois and Minnesota are direct delegated states, meaning that they are implementing directly the federal program and are not implementing their programs through a State Implementation Plan (SIP), as Wisconsin does. Iowa and Michigan, similar to Wisconsin, are SIP-approved states, so they are implementing the same federal programs, but through their own state rules. It is the goal of SIP-approved states to implement federal programs in accordance with the regulations set out in federal code. This results in similar requirements from state to state.
8. Summary of factual data and analytical methodologies used and how any related findings support the regulatory approach chosen:
Since the Department is proposing rules consistent with federal regulations, making consistency and clarification changes, and repealing rules as directed by the state legislature, the Department did not make use of any factual data or analytical methodologies in the rule development.
9. Analysis and supporting documents used to determine the effect on small business or in preparation of an economic impact report:
The economic impact of the proposed rule is expected to be minimal. When U.S. EPA adopts changes to the federal major air pollution control construction permit program, the Department immediately implements those changes through the state’s construction permitting program. For this reason, the consistency changes being proposed, that specifically name NOx as a precursor to ozone, will not have any additional economic impact on facilities obtaining major source air pollution construction permits (PSD permits).
The adoption of the PM2.5 increment will require additional analysis during the air construction permit reviews for minor sources (which may be small businesses) wishing to expand in areas where increment must be analyzed. However, because the Department has developed a weight of evidence approach to evaluate PM2.5 emissions against the increment, the Department does not anticipate that this additional analysis will cause noticeable delays in minor source permit issuance times and therefore, will not result in any significant impact to small businesses.
The Department has not been implementing the stage 2 vapor recovery program since 2012 when the state legislature terminated further implementation. Repeal of these outdated rules clarifies applicable requirements for the affected businesses and is not expected to have an adverse economic impact on them. As noted above, U.S. EPA already approved the removal of these requirements from Wisconsin’s SIP.
The portion of the rule that proposes to change the definition of volatile organic compounds (VOC) to make the rule consistent with the definition in federal regulations will provide clarity to businesses in how to calculate and report VOC emissions and on the applicability of regulations. This change is not expected to have a negative economic impact on businesses and, since the proposed change is specifically to exclude some organic compounds from the definition of VOC, the rule change could have a small, positive economic impact on certain facilities that use the excluded compounds.
10. Effect on small business (initial regulatory flexibility analysis):
The changes proposed in this rule are not expected to have an adverse economic impact on businesses, including small businesses. Small businesses are usually not major sources for purposes of the major source air pollution control construction permit program (PSD program) because they tend not to have large amounts of emissions. Since the Department is already implementing the PSD program, as required by U.S. EPA, the consistency changes being proposed in this rule will not have any additional economic impacts.
The adoption of the PM2.5 increment will require some additional analysis during the air construction permit review for some small businesses expanding in certain parts of the state, however, the Department does not anticipate that this additional analysis will cause noticeable delays in permit issuance times and therefore, will not result in any significant impact to the affected businesses.
The portion of the rule that proposes to change the definition of volatile organic compounds (VOC) to make the rule consistent with the definition in federal regulations will provide clarity to businesses in how to calculate and report VOC emissions and on the applicability of regulations. Small businesses affected include coating facilities, paint shops, autobody shops, and printing operations. This change is not expected to have a negative economic impact on these businesses however, because the proposed change is specifically to exclude some organic compounds from the definition of VOC. In fact, the rule change could have a positive economic impact on small businesses that use the compounds proposed to be excluded.
Many gasoline dispensing facilities are small businesses. The proposed repeal of the stage 2 vapor recovery program and related implementing rules will clarify applicable requirements for the affected small businesses and is not expected to have an adverse economic impact on them.
