additional information concerning the basis for emissions calculations for the Mamonal sources.
It is also impossible to confirm whether the cumulative predicted impacts from the refinery and
other sources in the Mamonal Industrial Area together would exceed applicable permissible
standards without having modeled all sources together.
There is no assessment of the impact of existing or proposed scenarios on ambient air pollutant
concentrations for pollutants other than PM10, SO2, and NO2. Thus, it is impossible to
determine whether or not the Project will create an issue with ozone, CO, heavy metals, or other
pollutants (e.g., VOCs). The EIA also does not address the effect of the Project on greenhouse
gas (GHG) emissions or global climate; however, an IDB study apparently estimated GHG
emissions of approximately 100,000 tons/year. The modeling also does not address potential
fugitive emissions of PM10 (e.g., coke and sulfur transfer) or VOCs (e.g., vents, floating roof
storage tanks, pressure relief valves, and loading and unloading of raw materials [crude] or
product).
Air dispersion modeling for the Site will be performed to predict the maximum ground level
concentration (GLCmax) of nitrogen oxides (NOX), sulfur dioxide (SO2), carbon monoxide (CO),
and particulate matter (PM10) from the expanded refinery within and around the refinery fence
line. The baseline emissions from current refinery operations plus the surrounding industrial
facilities will be established by conducting real-time ambient air sampling with the refinery
fence line, as well as at critical receptor locations (such as Membrillal, a restaurant,
Pasacaballos) around the refinery fence line.
New plant modifications will result in a reduction of air emissions from the new refinery and no
net impact to the Mamonal Industrial Area airshed. NO2 total load will increase but the
permissible limits will be met (Resolution 601, 2006, Tables 5 and 6). Confirmational air
sampling and dispersion modeling will be performed at the Site to establish a baseline. This
modeling program is designed to meet the issues listed in Table 7, using the following
protocols:
