Sec. 58.15  Annual air monitoring data certification.

    (a) The State, or where appropriate local, agency shall submit to 
the EPA Regional Administrator an annual air monitoring data 
certification letter to certify data collected at all SLAMS and at all 
FRM, FEM, and ARM SPM stations that meet criteria in appendix A to this 
part from January 1 to December 31 of the previous year. The senior air 
pollution control officer in each agency, or his or her designee, shall 
certify that the previous year of ambient concentration and quality 
assurance data are completely submitted to AQS and that the ambient 
concentration data are accurate to the best of her or his knowledge, 
taking into consideration the quality assurance findings.
    (1) Through 2009, the annual data certification letter is due by 
July 1 of each year.
    (2) Beginning in 2010, the annual data certification letter is due 
by May 1 of each year.
    (b) Along with each certification letter, the State shall submit to 
the Administrator (through the appropriate Regional Office) an annual 
summary report of all the ambient air quality data collected at all 
SLAMS and at SPM stations using FRM, FEM, or ARMs. The annual report(s) 
shall be submitted for data collected from January 1 to December 31 of 
the previous year. The annual summary report(s) must contain all 
information and data required by the State's approved plan and must be 
submitted on the same schedule as the certification letter, unless an 
approved alternative date is included in the plan. The annual summary 
serves as the record of the specific data that is the object of the 
certification letter.
    (c) Along with each certification letter, the State shall submit to 
the Administrator (through the appropriate Regional Office) a summary of 
the precision and accuracy data for all ambient air quality data 
collected at all SLAMS and at SPM stations using FRM, FEM, or ARMs. The 
summary of precision and accuracy shall be submitted for data collected 
from January 1 to December 31 of the previous year. The summary of 
precision and accuracy must be submitted on the same schedule as the 
certification letter, unless an approved alternative date is included in 
the plan.
