The data collected through this
information collection consist of ambient air concentration
measurements for the seven air pollutants with national ambient air
quality standards (i.e., ozone, sulfur dioxide, nitrogen dioxide,
lead, carbon monoxide, PM2.5 and PM10), ozone precursors,
meteorological variables at a select number of sites and other
supporting measurements. Accompanying the pollutant concentration
data are quality assurance/quality control data and air monitoring
network design information. The U.S. EPA and others (e.g., state
and local air quality management agencies, tribal entities,
environmental groups, academic institutions, industrial groups) use
the ambient air quality data for many purposes. Some of the more
prominent uses include informing the public and other interested
parties of an areas air quality, judging an areas (e.g., county,
city, neighborhood) air quality in comparison with the established
health or welfare standards (including both national and local
standards), evaluating an air quality management agency's progress
in achieving or maintaining air pollutant levels below the national
and local standards, developing and revising State Implementation
Plans (SIPs) in accordance with 40 CFR 51, evaluating air pollutant
control strategies, developing or revising national control
policies, providing data for air quality model development and
validation, supporting enforcement actions, documenting episodes
and initiating episode controls, air quality trends assessment, and
air pollution research.
The currently approved ICR
estimate of burden hours is 1,771,662. This ICR renewal burden hour
estimate updates the previous submittal. There is a decrease of
321,694 hours in the total estimated respondent burden compared
with that identified in the ICR currently approved by OMB. The
decrease in burden, labor costs, and capital/O&M costs from the
most recently approved ICR is due to an adjustment(s). There is an
adjustment decrease in the total estimated burden as currently
identified in the OMB Inventory of Approved Burdens. This decrease
reflects the consolidation of monitors into fewer sites,
consolidation of PAMS network burden estimates to avoid double
counting, termination of unnecessary monitors, and more efficient
automated procedures (e.g., moving from manual samplers to
automated continuous samplers) for measuring and reporting data.
The decrease is offset somewhat by the additional burden and cost
estimates included for asset management and sensors.
