These offsets must come from sources within either the same designated area as the new or modified source or from sources in another ozone nonattainment area with equal or higher nonattainment classification that contributes to a violation of the ozone ambient air quality standards in the same ozone designated area as the new or modified source. Areas of the country where air pollution levels of are above a NAAQS may be designated by USEPA as "nonattainment."

A geographic area that meets or does better than the primary standard is called an attainment area; areas that don't meet the primary standard are called nonattainment areas. The agency later designated 46 areas including at least part of 227 counties as nonattainment (not meeting the standards) effective July 20, 2012. Ozone Nonattainment Designation As noted in the previous section, EPA revised the NAAQS for ozone in 2015 by lowering the standard to 70 ppb.

Through successful state led implementation, numerous areas across the country are showing improvement and fewer areas are in nonattainment. KEY: NA = not applicable. Twelve areas were classified transitional in 1991. Nonattainment (not meeting a standard) Unclassifiable (not enough information to classify) Each designation is for a specific air quality standard. Clean Air Act Sections 172 and 182 State Implementation Plan (SIP) Submittal for Areas Designated as “Nonattainment,” “Marginal” under the 2015 8-Hour Ozone National Ambient Air Quality Standards, including Calumet, Hobart, North, Ross, and St. John townships in Lake County, and Clark and Floyd Counties (January 21, 2021) An area can be in attainment for one standard, and be in nonattainment or unclassifiable for another. The area of analysis for the Greater Connecticut area includes five ozone monitors. When an area is redesignated from nonattainment to attainment, the attainment area is considered to be a “maintenance” area, and the state is obligated to prepare a SIP that meets the requirements for 8-hour ozone maintenance areas. In ozone nonattainment areas like Houston-Galveston-Brazoria, owners and operators will need to obtain emission reduction credits that match the specific ozone precursor that is being increased. A geographic area that meets or does better than the primary standard is called an attainment area; areas that don't meet the primary standard are called nonattainment areas. In ozone nonattainment areas like Houston-Galveston-Brazoria, owners and operators will need to obtain emission reduction credits that match the specific ozone precursor that is being increased. The pollutants included in the inventory are annual emissions for CO, NOx, and VOC.

Ground-Level Ozone Pollution is Harmful to Public Health and the Environment EPA must remedy its violation of this mandatory duty to better protect public health and native ecosystems from ozone’s harmful effects. CMAQ provides funding to areas in nonattainment or maintenance for ozone, carbon monoxide, and/or particulate matter. FHWA approved BMT’s Revised 2040 MTP and HOU’s 2045 Regional Transportation Plan. 40 CFR 93 § 153 defines de minimis levels, that is, the minimum threshold for which a conformity determination must be performed, for various criteria pollutants in various areas. Once a nonattainment area meets the standards, EPA will designate it as "maintenance". Current Nonattainment Counties for All Criteria Pollutants. Isolated Rural Nonattainment Areas In isolated rural areas, as in other newly designated nonattainment areas, the one-year conformity grace period for the 2015 ozone NAAQS will begin on the effective date of an isolated rural area's initial nonattainment designation. 1 This severe nonattainment status has resulted in consistent “F” ratings for both measures.

In contrast, incidence of PM-10 pollution has decreased; many counties have achieved the PM-10 standard since 1987. Nationwide, the number of CO nonattainment areas has increased, though not dramatically. Marginal nonattainment is the least severe designation for an area not in compliance with the federal ozone limit.
