PART 58--AMBIENT AIR QUALITY SURVEILLANCE--Table of Contents
 
       Subpart C--State and Local Air Monitoring Stations (SLAMS)
 
Sec. 58.26  Annual State air monitoring report.

    (a) The State shall submit to the Administrator (through the 
appropriate Regional Office) an annual summary report of all the ambient 
air quality monitoring data from all monitoring stations designated 
State and Local Air Monitoring Stations (SLAMS). The annual report must 
be submitted by July 1 of each year for data collected from January 1 to 
December 31 of the previous year.
    (b) The SLAMS annual data summary report must contain:
    (1) The information specified in appendix F,
    (2) The location, date, pollution source, and duration of each 
incident of air pollution during which ambient levels of a pollutant 
reached or exceeded the level specified by Sec. 51.16(a) of this chapter 
as a level which could cause significant harm to the health of persons.
    (c) The senior air pollution control officer in the State or his 
designee shall certify that the annual summary report is accurate to the 
best of his knowledge.
    (d) For PM monitoring and data--
    (1) The State shall submit a summary to the appropriate Regional 
Office (for SLAMS) or Administrator (through the Regional Office) (for 
NAMS) that details proposed changes to the PM Monitoring Network 
Description and to be in accordance with the annual network review 
requirements in Sec. 58.25. This shall discuss the existing PM networks, 
including modifications to the number, size or boundaries of monitoring 
planning areas and optional community monitoring zones; number and 
location of PM10 and PM2.5 SLAMS; number and 
location of core PM2.5 SLAMS; alternative sampling 
frequencies proposed for PM2.5 SLAMS (including core 
PM2.5 SLAMS and PM2.5 NAMS), core PM2.5 
SLAMS to be designated PM2.5 NAMS; and PM10 and 
PM2.5 SLAMS to be designated PM10 and 
PM2.5 NAMS respectively.
    (2) The State shall submit an annual summary to the appropriate 
Regional Office of all the ambient air quality monitoring PM data from 
all special purpose monitors that are described in the State's PM 
monitoring network description and are intended for SIP purposes. These 
include those population-oriented SPMs that are eligible for comparison 
to the PM2.5 NAAQS. The State shall certify the data in 
accordance with paragraph (c) of this section.
    (e) The Annual State Air Monitoring Report shall be submitted to the 
Regional Administrator by July 1 or by an alternative annual date to be 
negotiated between the State and Regional Administrator. The Region 
shall provide review and approval/disapproval

within 60 days. After 3 years following September 16, 1997, the schedule 
for submitting the required annual revised PM2.5 monitoring 
network description may be altered based on a new schedule determined by 
the Regional Administrator. States may submit an alternative PM 
monitoring network description in which it requests exemptions from 
specific required elements of the network design (e.g., required number 
of core sites, other SLAMS, sampling frequency, etc.). After 3 years 
following September 16, 1997 or once a monitoring area has been 
determined to violate the NAAQS, then changes to an MPA monitoring 
network affecting the violating locations shall require public review 
and notification.
