Description:

One of the larger sources of fugitive emissions at the Bishop facility are leaks from pump seals. As part of a fugitive emissions reduction program at the plant, double mechanical seals were installed on many pumps with the poorest maintenance history (high leakage rate). With these double mechanical seals in place, a 100% reduction in fugitive emissions from these pumps has been realized.

Environmental Benefits:

Installation of the double mechanical seals has resulted in a decrease of approximately 10 tons per year of VOC emissions.
