Arizona Plan Revision: Redesignation ofAir Quality Control Regions
AGENCY: Environmental Protection Agency (EPA). ACTION: Final rulemaking.

SUMMARY: The EPA takes final action to approve the redesignation of the Air Quality ControlRegions (AQCR's) in Arizona, as requested by the Governor. The intended effect ofthis redesignation is "to improve the coordination and management ofongoing air, water, and transportation planningprograms by the state and six Arizona Councils of Government." EFFECTIVEDATE:November 10,1980. ADDRESS: A copy ofthe redesignation request is located at: The Office ofthe Federal Register, 1100 "L"Street NW., Room 8401, Washington, D.C. 20408. FOR FURTHER INFORMATION CONTACT. Louise P. Giersch, Director,Air and Hazardous Materials Division, EPA Region IX 215 Fremont Street, San Francisco, CA 94105, Attn. Douglas Grano, (415) 556-2938. SUPPLEMENTARY INFORMATION: Background

Under section 107 ofthe Clean Air Act, fourAQCR's located partly or entirely in Arizona were designated by the Administrator. Those AQCR's were described in the following sections of Title 40 ofthe CFR, and included the Arizona counties listedin parentheses: Sect. 81.36 Phoenix-Tucson Intrastate AQCR. (Gila, Maricopa, Pima, Pinal. Santa Cruz] 81.80 Clark-Mohave Interstate AQCR. (Mohave, Yuma) 81.99 Arizona-New Mexico Southern Border Interstate AQCIR (Cochise. Graham, Greenlee) 81.121 Four Comers Interstate AQCR, (Apache, Coconino, Navajo, Yavapal) Altogether, the AQCR'slisted above included the entire State ofArizona, plus portions offour adjoining States.

On July 8,1970, the Governor's Executive Order 70-2 established six Arizona Planning Districts, which comprise the entire State, asfollows: District 1-Maricopa County District 2-Pima County District 3-Apache, Coconino, Navajo,

and Yavapai Counties District 4-Mohave and Yuma Counties District 5-Gila and Pinal Counties District 6-Cochise, Graham, Greenlee,

and Santa Cruz Counties On February 4,1980 (45 FR 7544) the EPA, at the request of the Governor of Nevada, redesignated the Nevada portion (Clark County] ofthe ClarkMohave Interstate AQCR as the Las Vegas Intrastate AQCR and the Arizona portion (Mohave andYuma Counties) as the Mohave-Yuma Intrastate AQCR.
The Redesignation

In a January 26,1979 letter to the Administrator, the Governor ofArizona requested that the AQCR's in Arizona be redesignated to conform to the boundaries ofthe six Arizona Planning Districts. As aresult of this redesignation, Arizona will no longer share AQCR's with the neighboring States ofColorado, New Mexico, and Utah.

Section 107(e)(2) of the Clean Air Act,

as amended, requires the consent of the Governors of those neighboring States for the redesignation to take effect. The Governors ofColorado, NewMexico, and Utah have consented to the redesignation.
Effects ofRedesignation

The redesignation ofAQCR's in Arizona should result in improved coordination and management ofair, water, and transportation planning throughout the State, since the same District organizations now involved in wastewater management and transportation planning will also be responsible for air qualityplanning.

In addition, numerous administrative changes are beingmade toTitle 40, Part 52 ofthe CFR as a result ofthe redesignation. These changes are necessitated by revisions being made in 40 CFR Part 81 (Designation ofareas for airqualityplanning purposes), where all ofthe Arizona AQCR descriptions are being revised.

In Part 81, the names and descriptions of the AQCR's in §§ 81.36, 81.99, and 81.121 are being revised, andnew AQCR's are being added.

On February 8,1980 (45 FR 8670) the EPApublished a Notice ofProposed Rulemaking, proposing to approve the redesignation and inviting public comments on the proposal. One letter, from the Arizona Department ofHealth Services, wasreceived. The Department supports the redesignation and states that all six Arizona Councils of Governnent also support the proposal.

The EPA is approving this redesignationbecause it meets the requirements ofsection 107(e) of the Clean AirAct, as amended, which requires, in effect, that theredesignation be forpurposes ofimproved air quality management, and that ithave the consent ofthe Governors ofall affected states.

TheEPA has determined that this action is "specialized" and therefore not subject to theprocedural requirements ofExecutive Order 12044. (Secs. 107,110,301(a). Clean AirAct. as amended (42U.S.C. 7407.7410,7601(a))}

SUMMARY: This rulemaking changes the attainment status for portions of Milwaukee and Green Bay, Wisconsin, from attainment and unclassifiable, respectively, to nonattainment of the primary National Ambient Air Quality Standards (NAAQS) for sulfur dioxide. This change is requiredby recorded violations of the SO2 NAAQS in both Milwaukee and Green Bay. DATE: This designation is effective as of November 10. 1980.

FOR FURTHER INFORMATION CONTACT:. Robert B. Miller, Air Programs Branch, U.S. Environmental Protection Agency, 230 S. Dearborn St., Chicago, Illinois 60604, (312) 886-6031. SUPPLEMENTARY INFORMATION: This notice offinal rulemaking is issued under the authority ofsection 107 ofthe Clean AirAct, as amended. Section 107(d)(1) ofthe Clean Air Act required states to submit to the Administrator a list identifying all air quality control
areas, ofportions thereof,that had not attained the National Ambient Air Quality Standards (NAAQS). The Act further required that the Administrator promulgate this list, with such modifications as he deemed necessary. On March 3,1978, the Administrator promulgated nonattainment designations for Wisconsin for total suspended particulates (TSP), sulfur dioxide (S02), carbon monoxide (CO), photochemical oxidants and nitrogen dioxidqe (N02) (43 FR 8962, 40 CFR 81.350). Section 107(d)(5) ofthe Act provides that a state, from time to time, may review and revise its designations list and submit these revisions to the Administrator for promulgation. The criteria and policy guidelines governing these revisions and the Admiristrator's review of them are identical to those used in the original designations and are summarized in the Federal Register on March 3, 1978 (43FR 8962), September 11, 1978 (43 FR-40412) and October 5, 1978 (43 FR 45993).

On May 3, 1979, the Secretary ofthe Wisconsin Departmenf ofNatural Resources (DNR), acting for the Natural Resources Board, recommended redesignating portions ofGreen Bay and Milwaukee. This redesignation request included-a technical support document which recommends thatportions of Milwaukee and Green Baybe changed

- froni attainment and unclassifiable designations respectively, to nonattainment for S02. T e technical document was based on observed ' monitoring violations of the primary standard in.Green Bay and Milwaukee, This document was the subject ofpublic hearings on February 12 and 13, 1979, in Green Bay andMilwaukee; and the Board approved it inMarch 1979. On September 14,1979, the EPA proposed for public comment rulemaking approving Wisconsin's redesignation request [44 FR 53547].

Onlyone corporation responded to thisproposal with comments, These .comments and EPA's response to them follow:

Comment: The Wisconsin DNR and the EPA should use block averages rather than continuous running averages for ascertaining S02 concentrations. Further, the EPA should delay redesignation until the U.S. Court of Appeals for the District ofColumbia Circuit has reviewed the averaging Issue in "PPG Industries vs. Costle" (File No. 79-1708).

EPAResponse:It is the EPA'spolicy toreport continuousair quality monitoring data as running average concentratiofis. Running averages are specified in the "Guidelines for Interpretation ofAir Quality Standards" (February 1977). Continuous running averages represent actual air quality better than discrete block averages because people breathe in SO 2 from the ambient air on a continuous basis rather than in midnight "blocks". If EPA used block averages, it would evaluate for fewer 24-hour periods and would risk overlooking violations ofthe NAAQS.

Under either averaging procedure, however, the annual 1978 S02 monitoring data indicate-that there are 2

ormore exceedances of the 24 hour SO2 NAAQS. The S02 NAAQS is violated If there is more than Iexceedance annually. Therefore, on a technical basis the averaging issue is moot in this redesignation,

In regard to delaying redesignation pending the Court's review ofthe averaging issue, it isEPA policy to
assume its procedures are valid until they are overturned by a court. Once the court has rendered a decision in any such case, appropriate steps can be taken regarding the SIP,

Comment:The commentor claims that' most of the measured exceedances of the S02 NAAQS upon which thd Wisconsin DNR based its nonattainment redesignation request for Milwaukee are invalid because ofquality assurance problems.

EPA Response:The monitored S02 air quality data was measured at sites on the University ofWisconsin at Milwaukee North Campus (UWM) and Jones Island. The EPA has determined that these sites meet (or satisfy) the
