PART 58--AMBIENT AIR QUALITY SURVEILLANCE--Table of Contents
 
       Subpart C--State and Local Air Monitoring Stations (SLAMS)
 
Sec. 58.20  Air quality surveillance: plan content.


    By January 1, 1980, the State shall adopt and submit to the 
Administrator a revision to the plan which will:
    (a) Provide for the establishment of an air quality surveillance 
system that consists of a network of monitoring stations designated as 
State and Local Air Monitoring Stations (SLAMS) which measure ambient 
concentrations of those pollutants for which standards have been 
established in part 50 of this chapter. SLAMS (including NAMS) 
designated as PAMS will also obtain ambient concentrations of speciated 
VOC and NOX, and meteorological measurements. PAMS may 
therefore be located at existing SLAMS or NAMS sites when appropriate.
    (b) Provide for meeting the requirements of appendices A, C, D, and 
E to this part.
    (c) Provide for the operation of at least one SLAMS per criteria 
pollutant except Pb during any stage of an air pollution episode as 
defined in the plan.
    (d) Provide for the review of the air quality surveillance system on 
an annual basis to determine if the system meets the monitoring 
objectives defined in appendix D of this part. Such review must identify 
needed modifications to the network such as termination or relocation of 
unnecessary stations or establishment of new stations that are 
necessary. For PM2.5, the review must identify needed changes 
to core SLAMS, monitoring planning areas, the chosen community 
monitoring approach including optional community monitoring zones, 
SLAMS, or SPMs.
    (e) Provide for having a SLAMS network description available for 
public inspection and submission to the Administrator upon request. The 
network description must be available at the time of plan revision 
submittal and must contain the following information for each SLAMS:
    (1) The AIRS site identification form for existing stations.
    (2) The proposed location for scheduled stations.
    (3) The sampling and analysis method.
    (4) The operating schedule.
    (5) The monitoring objective and spatial scale of representativeness 
as defined in appendix D to this part.
    (6) A schedule for:
    (i) Locating, placing into operation, and making available the AIRS 
site identification form for each SLAMS which is not located and 
operating at the time of plan revision submittal,
    (ii) Implementing quality assurance procedures of appendix A to this 
part for each SLAMS for which such procedures are not implemented at the 
time of plan revision submittal, and
    (iii) Resiting each SLAMS which does not meet the requirements of 
appendix E to this part at the time of plan revision submittal.
    (f) Provide for having a PM monitoring network description available 
for public inspection which must provide for monitoring planning areas, 
and the community monitoring approach involving core monitors and 
optional community monitoring zones for PM2.5. The PM 
monitoring network description for PM10 and PM2.5 
must be submitted to the Regional Administrator for approval by July 1, 
1998, and must contain the following information for each PM SLAMS and 
PM2.5 SPM:
    (1) The AIRS site identification form for existing stations.

    (2) The proposed location for scheduled stations.
    (3) The sampling and analysis method.
    (4) The operating schedule.
    (5) The monitoring objective, spatial scale of representativeness, 
and additionally for PM2.5, the monitoring planning area, 
optional community monitoring zone, and the site code designation to 
identify which site will be identified as core SLAMS; and SLAMS or 
population-oriented SPMs, if any, that are microscale or middle scale in 
their representativeness as defined in appendix D of this part.
    (6) A schedule for:
    (i) Locating, placing into operation, and making available the AIRS 
site identification form for each SLAMS which is not located and 
operating at the time of plan revision submittal.
    (ii) Implementing quality assurance procedures of appendix A of this 
part for each SLAMS for which such procedures are not implemented at the 
time of plan revision submittal.
    (iii) Resiting each SLAMS which does not meet the requirements of 
appendix E of this part at the time of plan revision submittal.
    (g) Provide for having a list of all PM2.5 monitoring 
locations including SLAMS, NAMS, PAMS and population-oriented SPMs, that 
are included in the State's PM monitoring network description and are 
intended for comparison to the NAAQS, available for public inspection.
    (h) Within 9 months after;
    (1) February 12, 1993; or
    (2) Date of redesignation or reclassification of any existing 
O3 nonattainment area to serious, severe, or extreme; or
    (3) The designation of a new area and classification to serious, 
severe, or extreme, affected States shall adopt and submit a plan 
revision to the Administrator.
    (i) The plan revision will provide for the establishment and 
maintenance of PAMS. Each PAMS site will provide for the monitoring of 
ambient concentrations of criteria pollutants (O3, 
NO2), and non-criteria pollutants (NOX, NO, and 
speciated VOC) as stipulated in section 4.2 of appendix D, and 
meteorological measurements. The PAMS network is part of the SLAMS 
network, and the plan provisions in paragraphs (a) through (h) of this 
section will apply to the revision. Since NAMS sites are also part of 
the SLAMS network, some PAMS sites may be coincident with NAMS sites and 
may be designated as both PAMS and NAMS.
