Point-source air emissions from process
operations include volatile organic compounds, acid and basic gases and
minor amounts of fugitive dusts. Condensers and scrubbers remove the emitted
vapors and gases. The remaining vapors and gases are then transferred to a
central thermal oxidizer, which destroys 99% of the organic emissions. To
further reduce air emissions, Roche Carolina also operates a back-up thermal
oxidizer to be used when the primary unit is down for maintenance. Dust
collectors have been installed in each operating unit to remove 99.7% of
particulate matter. We have implemented a Leak Detection and Repair program
for all piping equipment components in order to |
 |
|
control the amount of fugitive air emissions
from process operations. The fugitive emissions monitoring program consists
of monthly visual inspections and annual instrument monitoring of all
valves, flanges, pumps, fittings, etc. in chemical service. |

We also have implemented a wastewater management program that includes a
complete evaluation and treatment of all wastewater streams prior to leaving
the Site for final treatment at the City of Florence Wastewater Treatment
Plant. Wastewater streams from pharmaceutical manufacturing operations are
tested and characterized prior to final disposition. The evaluation not only
includes testing of conventional pollutants, but also includes fate and
effects testing in order to verify suitability for discharge. We use a
10-gallon per minute steam stripper to remove volatile organic compounds
from the various wastewater streams. Further pretreatment includes removal
of suspended solids via a reactor/clarifier and pH adjustment prior to
discharge. Additionally, various in-line monitoring instruments have been
installed to ensure compliance with wastewater limitations. |
