TENASKA INCREASING ITS CARBON, EFFLUENT FOOTPRINT

(The City of Brownsville and the Brownsville Public Utility Board has been tight-lipped about the details surrounding the agreement between them and Tenaska in the construction of the 800 MegaWatt gas-fired electric plant they plan to build in the city. The information in this post was taken directly from their application to the Environmental Protection Agency and amended application to the Texas Commission on Environmental Quality.  Of particular interest is the section dealing with the prevention of significant deterioration (PSD) of greenhouse gases and the increase in effluent into the aquatically sensitive Brownsville Ship Channel.)

Tanaska states in the EPA application that the plant will emit the following contaminants:
1. nitrogen oxides (NOX)
2. carbon monoxide (CO) and
3. and volatile organic compounds (VOC)
4. Other air contaminants not listed above: NH3, H2, SO4 Mist and (NH4)2, and SO4 will also be released. The proposed Brownsville Generating Station is within a major facility category and subject to a 100 tpy (Tons Per Year) threshold for classification as a PSD major source.
Based on emissions estimates for the Brownsville Generating Station, the proposed project will be PSD major for

CO2: 3,169,143.4 Tons Per Year
CH4: 3,421.49 Tons Per Year
N2O: 80.254 Tons Per Year
SF6: 0.005 Tons Per Year
Total CO2e: 3,265,993 Tons Per Year
Now, in the published application for a permit from the TCEQ, Tenaska reveals that its former application to discharge water from its cooling tower blowdown and low volume wastes at a daily average flow not to exceed 2,200,000 per day will increase another 100,000 gallons daily to 2,300,000 per day.
They state that a Tier 2 review has determined that "no significant degradation of water quality is expected in the Brownsville Ship Channel, which has been identified as having exceptional aquatic life.
So we're supposed to believe that the quality of our air will remain the same once Tenaska starts pumping 3,265,993 tons per year of carbon monoxide a year into the environment and 2,300,000 gallons a day of cooling tower and waste into the Brownsville Ship Channel?
How long before we start getting unexplained fish kills in the channel and the bays and estuaries?
