further sulfur reductions now
In a recent application Valero used old (undated) modeling
results for 24 hour sulfur dioxide concentrations but did not provide modeling for the one-hour SO2 health standard, which St. Bernard air quality is in violations of. The 24 hour sulfur dioxide concentrations were listed as 321 ug/m3
SO2. The AAS and NAAQS is 365
ug/m3 SO2.. very close to the 321 ug/m3. LDEQ did not require Valero to model ANY emissions.
The people of St
Bernard Parish deserve better. When
was the last time Valero did modeling for its Meraux refinery? Has modeling
been done for the 2010 Sulfur Dioxide NAAQS at Valero? What are the results?
The modeling results information for PAH shows
Valero is very close to violating the Annual AAS and NAAQS for PAH of 0.06
ug/m3; the result is 0.04 ug/m3. How is
that protective of human health? PAH have been identified as carcinogenic, mutagenic, and teratogenic.
