NOTICE OF PUBLIC HEARING AND REQUEST FOR PUBLIC COMMENTS
HAWAII INFRASTRUCTURE STATE IMPLEMENTATION PLAN
DEPARTMENT OF HEALTH
STATE OF HAWAII
(Docket No. 25-CA-PA-13)
Pursuant to Hawaii Revised Statutes (HRS), Section 342B-13, and in accordance with Title 40 of the Code of Federal Regulations (CFR) Section 51.102, the Hawaii Department of Health (DOH) will accept written comments and hold a public hearing on Hawaii’s draft Infrastructure State Implementation Plan (I-SIP) submittal to address the 2010 1-Hour Sulfur Dioxide (SO2), 2012 Annual Fine Particulate Matter (PM2.5), and 2015 8-Hour Ozone (O3) National Ambient Air Quality Standards (NAAQS). The DOH plans to update the I-SIP with provisions from the current HRS, Chapter 342B, Air Pollution Control; and Hawaii Administrative Rules (HAR), Chapter 11-60.1, Air Pollution Control, in satisfying requirements of the Clean Air Act (CAA).
When the U.S. Environmental Protection Agency (EPA) establishes a new or revised NAAQS, CAA 110(a)(1) and (a)(2) requires all states to revise their State Implementation Plan (SIP) to show that they have the authority and programs needed to implement, maintain, and enforce the new or revised air quality standard. This type of submission is referred to as an Infrastructure State Implementation Plan, or I-SIP.
In accordance with CAA Section 110(a)(2), the I-SIP must adequately address each of the required elements to be approved by the EPA. These elements include the state’s legal authority, ambient air quality monitoring, permitting, enforcement, and emergency events. Once the I-SIP establishes an infrastructure surrounding the NAAQS revisions sufficient to implement, maintain, and enforce the standards across the state, the plan is approved.
Further information about the specific CAA Section 110(a)(2) elements can be found at the following website:
https://health.hawaii.gov/cab/files/2025/06/guidance_on_infrastructure_sip_elements_multipollutant_final_sept_2013.pdf
The current Hawaii I-SIP, which is codified in 40 CFR Part 52, Subpart M, satisfies some of the requirements of CAA section 110(a)(1) and (2). However, revisions are needed to update the SIP with Hawaii’s current regulatory provisions.
The DOH plans to submit a proposed SIP revision to the EPA for the 2010 1-Hour SO2, 2012 Annual PM2.5, and 2015 8-Hour O3 NAAQS. The submittal will include a Certification of Adequacy, which identifies HRS and HAR sections that meet the SIP requirements, and other supporting documents.
