SUPPLEMENTARY INFORMATION:

On March 19, 2013, the EPA published a direct final rule amending 40 CFR 81.305 to clarify the description of the Imperial Valley planning area, an area designated nonattainment for the National Ambient Air Quality Standard (NAAQS) for particulate matter of ten microns of less (PM₁₀) (78 FR 16792). In our March 19, 2013 direct final rule, we amended the entry for “Imperial Valley planning area” but did not intend to amend any other entry in the table listing PM₁₀ air quality planning area designations for the State of California. We believe, however, that the entry appearing directly after the entry for “Imperial Valley planning area” in the “California-PM-10” table and reading “Rest of State; 11/15/90; Unclassifiable” was deleted inadvertently when the entry for “Imperial Valley planning area” was amended. For example, see and compare the “California-PM-10” table within the July 1, 2012 version to the July 1, 2013 version of 40 CFR 81.305.

Consequently, the EPA is publishing this technical amendment to restore the “Rest of State” designation entry within ( printed page 57101) the 40 CFR 81.305 “California-PM-10” table as it appeared prior to our March 19, 2013 direct final action.

Part 81, Chapter I, Title 40 of the Code of Federal Regulations is amended as follows:

1. The authority citation for Part 81 continues to read as follows:

Authority: 42 U.S.C. 7401 et seq.

2. Section 81.305 is amended in the table for “California—PM-10” by adding an entry for “Rest of State” at the end of the table to read as follows:

80 FR 57100
