ADDITIONAL STATEMENT OF WORK
GRANT ACTIVITIES
The Performing Party will implement all grant activities in order to monitor ozone and
inventorying emissions, as required in Rider 7, Texas Commission on Environmental Quality,
Article VI of the General Appropriations Act of the 86th Legislature.
Task 1 (Monitoring of Pollution Levels)
1.1: A Category III QAPP for the Ambient Air Quality Monitoring Activities
Deliverable 1.1:A Category III QAPP for the Ambient Air Quality Monitoring Activities delivered
to the TCEQ in Microsoft Office Word
Deliverable Date 1.1: Draft QAPP within 30 calendar days after Task 1.2 is approved. The QAPP
must be accepted by the TCEQ prior to the start of technical activities.
Deliverable Cost 1.1: Included in personnel costs.
Task 1.2: Ambient Air Monitoring Network
Project Task 1.2 will be to continue to monitor ambient ozone concentrations at the five city air monitoring sites.
Relative humidity, temperature, and wind speed/direction will also be measured at each site and NO.
concentrations will be measured at all three current sites. This includes increasing the spatial resolution of NO.
measurements with the purchase and deployment of(2) additional NO. analyzers. The monthly data will be
available to the public by hosting summary data figures on the Coastal Bend Air Quality Partnership's website
(cbairquality.org). This task will directly support air monitoring requirements outlined in the State Implementation
Plan (SIP) and demonstrate NAAQS compliance. For instance, CAIR SIP consists of reducing NO.emissions
and the reduction evaluation depends on NO. monitoring. Up until our recent monitoring efforts, NO.monitors
were not present in the region.
NO.and VOCs are primary ozone precursors but the relationship between these precursors and ozone formation
is not linear. Despite these direct impacts on ozone formation, the Corpus Christi airshed did not have a NO.
monitoring station until we developed one this year. It does however have five centrally located VOC monitoring
stations(1 AutoGC, 1 TNMOC,4 canister).Depending on atmospheric conditions,ozone formation can be almost
exclusively controlled by NO.and mostly independent of VOCs.However,there are also conditions where ozone
formation can increase with VOC concentrations while not increasing or even decreasing with increasing NO..
Due to this nonlinear chemistry between precursors and product,determining whether ozone formation in an air
shed is "NO.or VOC limited" (i.e., sensitive to increases in NO.or VOC levels) has proven difficult. NO.data
from this year's monitoring campaign, suggest the Corpus Christi airshed is NO. limited but continuous NO.
monitoring is necessary to determine if the airshed is in a"NO.or VOC limited" regime. The NO.data provided
by this task along with currently available VOC data will help determine if stakeholders should focus resources
on future NO.or VOC controls to mitigate ozone increases.

Task 1.4.University of Houston Mobile Air Monitoring Campaign Corpus Christi Airshed
A University of Houston team lead by Dr. Jimmy Flynn will perform mobile air monitoring in the
Corpus Christi airshed over a four-day period in early November. The campaign will be focused
on determining ozone and ozone precursor levels in areas of the airshed not currently covered by
stationary monitoring with specific attention to the growing industrial footprint and shipping lanes.
The mobile monitoring will tentatively cover urban areas along the full perimeter of Corpus Christi
Bay(i.e. from Port Aransas moving south and looping around the bay to Aransas Pass). Specific
measurements will include 03,NO,NOR,NON,CO,SO2,HCHO,CH4,unspeciated sum of reactive
alkenes, bulk and specific VOCs via AROMA-VOC, 3-wavelength PM2.5 scattering and
absorption, PM2.5 size distribution (0.13-2.5 gm),ceilometer,jNO2, T/P/RH/WS/WD, GPS, total
sky camera. In addition, while not performing mobile measurements, stationary measurements
directly adjacent to the Gulf of Mexico will allow characterization of the chemical composition of
air being transported into Corpus Christi from the Gulf. The campaign will also allow for
comparison to similar data provided by a previous similar air monitoring project,AQRP 20-003:
Characterization of Corpus Christi and San Antonio Air Quality During the 2020 Ozone Season
and the mobile monitoring done as part of 2022-2023 Rider 7 funding. The primary deliverable

Task 2: Detailed Analysis of Ambient Monitoring
Task 2 will report atmospheric conditions and chemical precursor concentrations associated with high or
standard exceeding ozone measurements in the Corpus Christi airshed. Atmospheric conditions (i.e., wind
direction,wind speed, relative humidity,temperature)will be obtained directly at each site while precursor data
(i.e., NOX and VOC) will be obtained from the nearest monitoring site. The report will be developed through
the below investigations and analyses:task will support the State Implementation Plan by demonstrating NAAQS
compliance and reporting conditions that may lead to nonattainment.
• Evaluate wind speeds, wind directions, relative humidity and temperature associated with
background and high ozone events to determine the local conditions and sources associated with
high/low ozone levels
• Determine diurnal and seasonal trends associated with background and high ozone levels
• Determine 24-hour air mass back trajectories using NOAA HYSPLIT software to determine source

Task 3: Soil biogenic NOx flux characterization
A primary purpose of Rider 7 funds is to enhance ozone precursor emission inventory accuracy.
While stationary NOW sources and vehicle emissions are relatively straightforward to measure,
complexity arises with sources such as biogenic emissions. SNOW, a byproduct of denitrification
and nitrification in soils,is influenced by various factors such as soil moisture,soil/air temperature,
soil type, and available nitrogen. This emission can spike significantly following fertilization and
rain events,leading to ozone formation and exacerbating air quality challenges(Romer et al.,2018;
Tong et al., 2021). Current numerical models,particularly the widely used Model of Emissions of
Gases and Aerosols from Nature (MEGAN), tend to underestimate soil biogenic NOW (SNOW)
emissions. For instance, Oikawa et al., 2015 found that the numerical models when compared to
direct chamber flux studies can underestimate SNOW by a factor of ten. The limitations of these
models underscore the need for direct flux measurements from diverse land types under varying
soil temperature and moisture conditions.
To address this gap in understanding,we propose a comprehensive approach in South Texas. Over
the course of one year, we will conduct monthly SNOW soil chamber flux measurements across
different land use types, including crops, forested areas, flooded vegetation, urban grasses, and
bare soil ground. These direct flux measurements will be accompanied by soil temperature, air
temperature and soil moisture measurements to serve as valuable inputs to improve the accuracy
of numerical models. Furthermore,we will leverage the National Land Cover Database to model
SNOW emissions in Nueces and San Patricio Counties according to land cover type.This integrated
approach aims to provide a more robust foundation for emission inventories and, consequently,
enhance our ability to develop effective NOW mitigation strategies. The SIP requires areas of
nonattainment to provide emission inventories,and while the region is currently in attainment,this
task falls in line with these SIP requirements as a means of understanding where NOW emissions
can be reduced to stay in attainment.
