I. INTRODUCTION
This report presents the results of an air quality impact analysis conducted for the
Boynton Beach Mall amended Application for Development Approval/Development of
Regional Impact (ADA/DRI). This analysis was conducted following the Florida
Department of Environmental Regulation (FDER) Interim Guidelines for Evaluatine
the Air Oualitv Imoacts of Indirect Sources of Carbon Monoxide Emissions [I]. An
indirect source is defined as a building, structure, installation, or development which
attracts motor vehicles. The purpose of the guidelines is to predict the impact of
indirect sources on future air quality conditions in the project vicinity.
Specifically, the analysis examines the generation and dispersion of carbon monoxide
(CO)--the most prevalent air emission from motor vehicles. The results of the analysis
indicate whether or not motor vehicle emissions associated with the project would
contribute to CO concentrations above the Ambient Air Quality Standards (AAQS).
The one- and eight-hour AAQS for CO are 35 and 9 parts per million (ppm),
respectively--Ievels considered by the U.S. Environmental Protection Agency (EPA) to
pose no significant health risk.
Based on recommendations from the Treasure Coast Regional Planning Council
(TCRPC), the intersections of Military Trail/Old Boynton West Road and Congress
Avenue/Old Boynton West Road were analyzed.
The remainder of this report has been organized to provide a concise summary of the
air quality impact analysis. Section II presents a brief explanation of the methodology
and models used. Section III is a compilation and discussion of the results. Section IV
presents brief concluding remarks. Finally. the Appendix includes supplemental
information developed in support of this analysis.
II. METHODOLOGY AND MODELS
Following the FDER guidelines, the analysis was accomplished using the EPA
approved TEXIN2 intersection model [2]. Using this model, the generation and
dispersion of emissions from both free flow and excess motor vehicles were analyzed.
Free flow emissions are those attributable to moving motor vehicles. Excess emissions
are those associated with stopped, accelerating, and decelerating motor vehicles.
Future year traffic volumes were obtained from data developed in support of
Question 31 of the ADA/DRI (Public Transportation Facilities: Transportation
Considerations). Consistent with these forecasts. the air quality analysis was
accomplished for the year 1989, the only phase of this project.
Data concerning vehicle mix, operating mode, stability class, and wind speed for the
TEXIN2 computer model were based on FDER recommendations including 1990
emission factors. These worst-case, peak-hour traffic and meteorological factors are
summarized in Table 1. Also. in conformance with the FDER guidelines. a series of
36 wind directions (00.3500 at 100 intervals) were examined over the modeling grid in
order to determine the most critical wind angles within each study area.
The computer modeling of worst.case traffic and meteorological data was conducted
for the peak one-hour period. To account for the long-term variation in the traffic

and meteorological data over time, FDER recommends site-specific persistence factors
be used to convert the one-hour modeled conditions to comparable worst-case eight-
hour conditions. In this way, the results can be compared to the AAQS which are also
based on one-hour and eight-hour time periods. The following FDER one-hour to
eight-hour persistence factors were used: Military Trail/Old Boynton West Road -
0.50, Congress Avenue/Old Boynton West Road - 0.53.
In the absence of site-specific background CO monitoring data, the FDER
recommended default value of 2.0 ppm was used. The background CO value was
added to the modeled one-hour and the computed eight-hour results to account for CO
sources beyond the study area.
Because the computer printouts for TEXIN2 are too voluminous to be included in this
report, only worst-case receptor results at each intersection analyzed are contained in
the Appendix.
III. RESULTS
The results of the 'air quality impact analysis are presented in Table 2. As previously
stated, these values represent potential worst-case conditions. For ease in assimilating
the data, CO concentrations are compiled to include contributions from future-year
traffic emissions and background CO levels. For comparative purposes, the
corresponding one- and eight-hour AAQS for CO are also shown.

Ambient Air Quality Standards (AAQS) for carbon monoxide levels considered not to
pose any significant health risk:
· One-Hour - 35 parts per million
· Eight-Hour = 9 parts per million

As shown in Table 2, in the vicinity of the Military Trail/Old Boynton West Road
intersection, the highest predicted worst-case one- and eight-hour CO concentrations
with existing geometry are 10.9 and 6.4 ppm, respectively. Based on these data, no
exceedances of either the one- or eight-hour AAQS for CO are likely to occur at any
of the six receptors analyzed.
Also shown in Table 2, in the vicinity of the Congress Avenue/Old Boynton West
Road intersection, the highest predicted worst-case one- and eight-hour CO
concentrations with existing geometry are 14.7 and 8.7 ppm, respectively. Based on
these data, no exceedances of either the one- or eight-hour AAQS for CO are likely to
occur at any of the eight receptors analyzed.
IV. CONCLUSION
The results of the air quality impact analysis conducted for the Boynton Beach Mall
indicate that under simulated worst-case traffic and meteorological conditions, motor
vehicle emissions associated with the project will not cause, nor contribute to, an
exceedance of the AAQS for CO in the vicinity of the Military/Old Boynton West
Road and Congress Avenue/Old Boy ton West Road intersections.
While it is generally concluded that computer modeling is a useful method of assessing
the relative magnitude of traffic-related air quality impacts near roadways and
intersections, it tends to over-predict the absolute CO concentration measured in the
field. This is because all of the simulated worst-case meteorological and traffic
conditions are not likely to occur simultaneously. For example, wind velocities in the
vicinity of the proposed Boynton Beach Mall project are characteristically greater than
6
simulated in this analysis, thereby enhancing the natural ventilation and dilution
mechanisms of the atmosphere. As such, the CO levels reported in the analysis are
conservatively high estimates.
In addition, the proposed improvements to the Congress A venue/Old Boynton West
Road intersection identified in the ADA/DRI could further reduce CO levels
forecasted in this analysis by increasing motor vehicle mobility and reducing motor
vehicle emissions.
