Approval and Promulgation of Implementation Plans - Designation of Areas for Air Quality Planning Purposes - State of California - PM-10 (US Environmental Protection Agency Regulation) (EPA) (2018 Edition) The Law Library presents the complete text of the Approval and Promulgation of Implementation Plans - Designation of Areas for Air Quality Planning Purposes - State of California - PM-10 (US Environmental Protection Agency Regulation) (EPA) (2018 Edition). Updated as of May 29, 2018 EPA is finalizing its proposal to affirm its October 30, 2006, determination that the San Joaquin Valley nonattainment area (SJV or the Valley) in California has attained the National Ambient Air Quality Standard (NAAQS) for particulate matter with an aerodynamic diameter less than or equal to a nominal 10 micrometers (PM-10). EPA proposed to affirm the determination of attainment in order to take comment on the exclusion from a determination of attainment of PM-10 exceedances that were caused by exceptional events. EPA is concurring with the State's request to flag exceedances which occurred in the SJV as being caused by exceptional events, i.e., high winds. EPA is also concurring with the Santa Rosa Rancheria Tribe's request to flag, as due to an exceptional event, PM-10 exceedances which occurred on tribal lands located within the boundaries of the SJV. EPA is further finding that these exceedances at the Santa Rosa Rancheria (SRR) should be excluded from use in determining attainment because the exceedances occurred while the monitor was operating in very close proximity to construction activities and, as such, the monitor was not properly sited during that time for purposes of comparison to the NAAQS. As a result, EPA is affirming its determination that the SJV has attained the PM-10 standard based on EPA's evaluation of quality-assured data through 2006.
