A. Document the steps which will be taken to contain fugitive dust
during site preparation and construction of the project. If site
preparation includes demolition activities, provide a copy of any
notice of demolition sent to the Florida Department of Environmental
Regulation (FDER) as required by the National Emission Standards
for Asbestos, 40 CFR Part 61, Subpart M.
To be addressed at a later date, if required.
B. Specify structural or operational measures that will be implemented
by the development to minimize air quality impacts (e.g., road
widening' and other traffic flow improvements on existing roadways,
etc.). Any roadway improvements identified here should be
consistent with those utilized in Question 21, Transportation.
To be addressed at a later date, if required.
C. Complete Table 22-1 for all substantially impacted intersections
within the study area, as defined in Map J, and all parking facilities
associated with the project. Using the guidance supplied or
approved by the Florida Department of Environmental Regulation,
determine if detailed air quality modeling for carbon monoxide (CO)
is to be completed for any of the facilities listed in the table.
Air Quality modeling will be conducted (if required) to ensure that the
traffic generated by the project will not cause an exceedance in the
National Ambient Air Quality Standards for carbon monoxide. The
transportation data generated for the DDRI Update will be utilized to
perform the Air Quality modeling to address the requirements of the DDRI
Question 22. Considering the size of the study area, the MOBILE module
of the FSUTMS model will be used to estimate cumulative vehicular
emissions from the downtown area. Cumulative emissions will be
compared with allowable emissions published in the latest update of the
Florida's State Air Implementation Plan (SIP). Modeling parameters will
be consistent with the Florida Department of Environmental Protection
Guidelines for Evaluating the Air Quality Impacts of Indirect Sources,
June 1994, and will be reviewed with FDEP and DERM staff. The air
quality study will be initiated at the request of the reviewing agency after
Question 21 has been found sufficient by the SFRPC.

t Specify source type as either intersection, surface parking area, or parking deck. For each ersec ion
provide an approach volume for each link. For each parking facility provide the total (incoming and outgoing)
volume.
2 These should be compatible with maximum service volumes utilized in Question 21, Transportation.
D. If detailed modeling is required, estimate the worst case one -hour
and eight -hour CO concentrations expected for each phase through
buildout for comparison with the state and federal ambient air
quality standards. Utilize methodology supplied or approved by the
Florida Department of Environmental Regulation for making such
estimates. Submit all air quality modeling input and output data
along with associated calculations to support the modeling and
explain any deviations from guidance. Provide drawings of site
geometry and coordinate information for each area modeled. Show
the location of the sources and receptor sites.
Modeling assumptions should consider federal, state, and local
government programmed link and intersection improvements with
respect to project phasing. Any roadway improvements utilized in
the model should be consistent with those used in Question 21,
Transportation. Provide verification of any assumptions in the
modeling which consider such programmed improvements. It is
recommended that air quality analyses be completed concurrently
and in conjunction with the traffic analyses for the project.
Modeling will be addressed once the traffic study is completed and
impacts are identified.
E. If initial detailed modeling shows projected exceedance(s) of
ambient air quality standards, identify appropriate mitigating
measures and provide assurances that appropriate mitigating
measures will be employed so as to maintain compliance with air
quality standards. Submit further modeling demonstrating the
adequacy of such measures.
To be addressed at a later date, if required.
