existing nonferrous metals industry

sources R9-3-522 Standards of performance for

existing gravel orcrushed stone processing plants Appendix 8 Procedures for utilizing the

sulfur balance method for determining sulfur emissions As described below, these rules revisions are administrative and do not significantly impact current emission control requirements.

In rule R9-3-101 a number of definitions have been revised tO provide clarification and improve the enforceability ofthe SIP. Revisions in rule R9-3-219 specify ozone rather than photochemical oxidant as the criteria pollutant. The wording ofrules R9-3-502
to R9-3-522 has been adjusted to reflect the change in the names and boundaries ofthe Arizona Air Quality Control Regions. And, inAppendix 8 the citation for the testmethod has been updated.

Under Section 110 of the Clean Air Act as amended, and 40 CFR Part 51, EPA is required to approve or disapprove thepe regulations as SIP revisions. All rules submitted have been evaluated and found to be in accordance with EPA policy and 40 CFR Part 51. EPA's detailed evaluation ofthe submitted rules is available at the EPA Library in Washington, D.C., and the Region 9 office.

It is the purpose ofthis notice to approve all the rulerevisions listed above and to incorporate them into the Arizona SIP. This is being done without priorproposal because the revisions are noncontroversial, have limited impact, and no comments are anticipated. The public shouldbe advised that this action will be effective 60 days from the date of this Federal Registernotice. However, if notice is received within 30 days that

someone wishes to submit adverse or critical comments, the approval will be withdrawn and a subsequent notice will be published before the effective date. The subsequent notice will indefinitely postpone the effective date, modify the final action to a proposed action, and establish a comment period.

Under 5 U.S.C. 605(b), the Administrator has certified that SIP approvals do not have a significant economic impact on a substantial number ofsmall entities. (See 46FR 8709.) The Office ofManagement and Budget has exempted this rule from the requirements ofSection 3 ofExecutive Order 12291.

Under the Clean Air Act. any petitions for judicial review ofthis action must be filed in the United States Court of Appeals for the appropriate circuit by (60 days from today). This action may not be challenged later in proceedings to enforce its requirements.

Incorporation by reference ofthe State Implementation Plan for the State ofArizona was approved by the Director ofthe Federal Register on July 1, 1982. (Sections 110 and 301(a) of the Clean Air Act.

Approval and Promulgation of State Implementation Plans; Colorado

AGENCY: Environmental Protection Agency. ACTION: Finalrulemaking.

SUMMARY: The U.S. Environmental Protection Agency (EPA)is approving revisions to the Colorado State Implemention Plan (SIP]. The revisions establish plans for achieving and maintaining the National Ambient Air Quality Standard (NAAQS] for lead in Denver, Grand junction, and Pueblo in accordance with Section 110 ofthe Clean Air Act (theAct]. The Governor ofColorado submitted the revisions to the EPA on April 12, 1982, following Public Hearing and adoption by the Colorado Air Quality Control Commission, both on February 25, 1982. DATES: This action will be effective on November 29, 1982 unless notice is received by October 28, 1982, that

someone wishes to submit adverse or critical comments. ADDRESSES: Copies ofthe revision are available forpublic inspection between 8:00 a.m. and 4:00 p.m. Monday through Friday at the following offices: Environmental Protection Agency,

SUPPLEMENTARY INFORMATION: On October 5, 1978, the EPA established an NAAQS for lead in accordance with Section 109 ofthe Act 43 FR 46246 (1978). Under Section 110 of the Act, each State must submit to EPA a plan to attain and maintain the NAAQS. The 

### Act alsodirects EPAto review the State plan to determine whether itmeets requirements established under Section 110oftheAct. Ifrequirements are met, theEPA can approve the plan. Requirements for an adequate lead SIP

are established in the 40 CFRPart 51 Subpart E-Control Strategy forLead. Based on those requirements, theEPA finds that the subject plan to achieve the lead NAAQS for Colorado is approvable.

Analysis ofair quality data collected by the State ofColorado for 1974 through 1979 showed violations ofthe lead NAAQS in three areas: Denver, Grand Junction, and Pueblo.The EPA hired a consulting firm (ETA Engineering, Inc.) to prepare a technical analysis that identified lead emission

sources andpredicted future ambient concentrations. The State was expected to prepare the lead SIPbased on that technical analysis.

The analysis found that,in Denver and Grand Junction, motor vehicle emissions were largely responsible for the monitored standards violations; in Pueblo, both motor vehicle emissions and lead particulate emissions from the CF&I Steel Mill were responsible forthe monitored violations. However, modeling by thecontractor showed that each area would meet the lead NAAQS by 1982 at the latest,based on implementation ofprograms that were already planned. Therefore, no additional control strategies were needed in the SIPto provide attainment. As required under40 CFR Subpart E,the statehas adoptedregulations that control lead emissions. Although not described in the subject submittal, the EPA considered these regulations as part of thelead SIP. InDenverand Grand Junction, the following factorsresult in the emissions reductions needed to meet thelead NAAQS: thefederal program to improve fuel economy, the federal program to decrease the average lead content of gasoline, and an increase in the proportion ofcatalyst cars (whichuse unleaded gas] over noncatalyst cars (whichuse leaded gas] due tonormal fleet turnover. InPueblo, airpollution control equipment installed at CF&I subsequent to the year in which violations were measured reduced lead emissions from the plant substantially. In fact,no violations havebeen measured since 1974. Theemissions reductions at CF&I and those expected from federal programs and fleet turnover achieve the reductions needed to maintain thelead NAAQS.

TheEPA hasreviewed the technical analysis in the SIP Revision and found that the analysis is appropriate. The SIP was submitted to EPA following Public Hearing asrequired under40 CFIRPart 52. Consequently, we find that the Colorado lead SIPRevision are approvable.

EPA is today approving these revisions. Thepublic is advised that this action will be effective (60 days]. However, ifwe receive written notice by (30 days] that someone wishes to submit adverse or critical comments, this action will be withdrawn and two subsequent notices will be published before the effective date. One notice willwithdraw this final action and anotherwill begin a
new rulemaking by announcing a proposal ofthe action and establishing a commentperiod.

Under Section 307(b)(1) ofthe Clean AirAct,petitions forreview ofthis action mustbe filed in theUnited States Court ofAppeals for the appropriate circuitby November29, 1982. This action maynotbe challenged later in proceedings to enforce itsrequirements (See 307(b)(2)).

The Office ofManagement and Budget has exempted this rule from the requirements ofSection 3ofExecutive Order 12291.
