### Preparation, Adoption,and Submittal of State Implementation Plans; PM-IO, Sulfur Dioxide, and Lead Nonattainment and Unclassiflable Area Designations
AGENCY: Environmental Protection Agency (EPA). ACTION: Information notice. SUMMARY: Pursuant to sections 107 (d)(3) and (d)(5) ofthe Clean Air Act as amended by the Clean Air Act Amendments of1990 (Pub.L. 101-549, Nov. 15, 1990) (the Act), EPA is authorized to promulgate designations ofnew areas (orportions thereof) as nonattainment, attainment, or unclassifiable forparticulate matter less than or equal to 10 microns (PM-IO) sulfur dioxide (SO2), and lead national ambient air quality standards (NAAQS). As required by the Act, EPA has provided notification to all affected States that the lead designations for certain areas should be submitted or that EPA believes that an area's PM-10 or SO 2 designation should be revised. 

### Pursuant to sections 107(d)(4)(B] and (d)(1)(C) ofthe Act, certain other areas were designated as nonattainment, by operation oflaw,forPM-10 and SO2, 

### respectively. ForPM-10, this includes
areas previously identified as group I and other areas withviolations of the PM-10 NAAQS prior to January 1, 1989. 

### For SO 2

### ,this includes areas which, prior to enactment,were designated as not attaining the primary and secondary SO2 NAAQS.



### TheEPA is, by this notice,identifying those PM-la, SO2, and lead areas for which EPA has provided notification to the affected States that EPAbelieves the area's designation should be revised to nonattainment orunclassifiable.
ADDRESSES: 

### Information supporting the basis fornotifying a State that EPA believes an area's PM-10 or SO2, 

### designation should be revised to nonattainment or unclassifiable, as well
as the basis forrequiring Statesto submit new nonattainment or unclassifiable designations forlead, can be obtained frrom therespective EPA Regional Office which serves the State where the affected area is located. The contracts and addresses ofthe Regional Offices are:

On July 1,1987, theEPA promulgated revised NAAQS for particulate matter (PM) (52 FR 24634), replacing total suspended particulates (TSP) as the indicator for PM with a new indicator called PM-10 that includes only those particles with an aerodynamic diameter less than or equal to a nominal 10 microns. At the same time, EPA set forth regulations for implementing the revised particulate matter standards and 

### 16274

### Federal Register / Vol. 56, No. 77 / Monday, April 22, 1991 / Rules and Regulations

announced EPA's State implementation plan (SIP) development policy elaborating PM-10 control strategies necessary to assure attainment and maintenance ofthe PM-10 NAAQS (see generally 52 FR 24672). The EPA adopted a PM-10 SIP development policy dividing all areas of the country into three categories based on their probability ofviolating the new NAAQS: (1) Areas with a strong likelihood ofviolating the new PM-10 NAAQS and requiring substantial SIP adjustment were placed in group I;(2)
areas where attainment ofthe PM-10 NAAQS was possible and existing SIP's needed less adjustment were placed in group II; and (3) areas with a strong likelihood ofattaining the PM-l0 NAAQS and,therefore, needing adjustments only to their preconstruction review program and monitoring network were placed in group 111 52 FR 24672, 24679-24682).

Pursuant to section 107(d](4)(B) of the Act, areas previously identified as group I and other areas which had monitored violations of the PM-10 NAAQS prior to January 1, 1989were, by operation of law, designated nonattainment for PM10. Descriptions ofthe areas identified

as group I and II areas were clarified in
a Federal Register notice on October 31, 1990 (55FR 45799). That notice also identified group II areas which violated the standards as ofJanuary 1, 1989. The EPA has announced all ofthe areas that
were designated nonattainment by operation oflaw for PM-10 upon enactment ofthe Act in a Federal Register notice dated March 15, 1991 (56 

### FR 11101).

In addition, EPA is authorized to promulgate the designation ofnew areas as nonattainment forPM-10 pursuant to section 107(d)(3) ofthe Act on the basis of air quality data, planning and control considerations, or any other air qualityrelated consideration that the Administrator deems appropriate. Based upon available information, EPA has notified the governors ofthose States with areas which recorded violations of the PM-10 NAAQS on or after January 1, 1989 and indicated that EPA believes these areas should be redesignated as nonattainment. After notification, the governor ofeach affected State must submit to EPA the designation which he
orshe considers appropriate for each
area in question within 120 days. For administrative efficiency reasons, EPA requested the States to submit the designations by March 15, 1991 (the date the lists ofdesignations for all ozone and carbon monoxide areas are due from the governor ofeach State pursuant to section 107(d)(4)(A) ofthe Act). No later than 120 days after the State's response, ifany, EPA must promulgate those redesignations which EPA deems necessary and appropriate.

The EPA isby today's notice announcing that EPAbelieves available air quality information indicates that 16
areas should be redesignated as nonattainment forPM-lO, and that EPA has so notified the governors of the affected States. A list ofthe 16 areas is provided below in table I. As discussed above, after consideration ofthe State's submittals, ifany, EPA will promulgate the designations which EPA deems appropriate and necessary. Pursuant to section 189(a)(2)(B) ofthe Act, States must submit PM-10 SIP's for these areas to EPAwithin 18 months afterEPA promulgates the nonattainment designation. Background for S02

Following the Clean Air Act Amendments of1977, EPA published
areas identified by the States as nonattaninment, attainment, or unclassifiable. Any area designated as not attaining the primary or secondary SO2 NAAQS as ofthe date ofenactment of the 1990 Amendments was designated nonattainment forS0 2 by operation of law upon enactment,pursuant to section 107(d)(1)(C)(i) oftheAct. The EPAwill formally codify these designations in 40 CFR part 81 when EPA codifies the designations forother pollutants.

In addition, as described above, EPA is authorized to promulgate the designation ofnew areas (orportions thereof) as nonattainment for SO2, pursuant to section 107(d)(3) ofthe Act,
on the basis ofair quality data,planning and control considerations, or any other air quality-related consideration the Administrator deems appropriate. Based upon available information,EPA has notified the governors ofthe affected States that EPA believes certain areas should be designated as nonattainment for SO2. After notification, the governor of each affected State must submit to EPA the designation he or she considers appropriate foreach area in question within 120 days. For the reasons described above, the EPArequested the States to submit the designations by March 15, 1991. No later than 120 days after the State's response, ifany, EPA must promulgate those redesignations EPA deems necessary and appropriate.

As mentioned above, for administrative efficiency reasons, those SO2 areas designated nonattainment by operation oflaw upon enactment of the Act will be formally codified in 40 CFR part 81 when EPA codifies the designations forother pollutants. The EPA is by today's notice announcing that EPA has notified the governors of affected States thatEPA believes 13 areas, listed in table II ofthis notice, should be designated nonattainment for SO2.

Pursuant to section 191(b) ofthe Act, States must submit SIP's by May 15, 1992 for those S02 areas which are designated nonattaiment by operation ot law for the primary SO.0 NAAQS and which lack a fully-approved SIP. For those SO 2 areas designated nonattainment after enactment, States must submit SIP's to EPA within 18 months after promulgation ofthe nonattainment designation, pursuant to section 191(a) of the Act. Background for Lead

In 1978, whenEPA promulgated the lead NAAQS, it was not authorized to designate areas nonattainment, attainment, or unclassifiable. Under section 107(d)(5) ofthe Act,EPA is now authorized to require States to designate

areas (orportions thereof) as nonattainment, attainment, or unclassifiable for lead. Sections 107 (d)(1) and (d)(5) ofthe Act permit EPA to require States to submit lead designations in a timeframe that EPA deems reasonable, but no sooner than 120 days after date ofnotification nor later than 1 year after the date of notification. For the reasons described above, the EPA requested the States to submit the designations by March 15, 1991. The EPA must then promulgate these designations no later than 1 year after notifying the State of the requirement to submit designations of certain areas, but first notifying the affected State ofany modifications EPA deems necessary and appropriate to the State's submittal.

By today's notice, EPAis announcing that it has notified the governors of affected States that they should proceed to designate as nonattainment those

areas that have recorded violations of the lead NAAQS. In addition, EPA has requested the governors to designate as unclassifiable those areas that contain stationary lead sources which EPA believes to be capable ofviolating the lead NAAQS, but for which existing air quality data are insufficient to designate
as attainment ornonattainment. A list of those areas EPAbelieves should be designated tononattainment and unclassifiable for lead is provided in table III below.

Any State containing an area thatis ultimately designated as nonattainment for lead must submit a SIP toEPA within 18 months of the promulgation ofthe nonattainment designation, pursuant to section 191(a) ofthe Act.
