Air

General Dynamics NASSCO has adopted numerous safeguards in our production processes to reduce airborne pollutants and protect air quality.

Significant investments include:

• Blast and Paint Facility: NASSCO's 66,000 square foot blast and paint facility came online in 2009. Abrasive blasting and painting activities are enclosed in a controlled space, collecting 100% of the particulate matter emissions during blasting and destroying 96% of volatile organic compounds (VOCs) emitted during painting. When abrasive blasting cannot be accomplished within the facility, it is conducted in a fully contained area to reduce dust. When painting must be performed outside, shrouding is used to contain overspray and emissions.
• No Paint Thinning: Paint is applied without the addition of thinners, which reduces the release of VOCs.
• Filtration: Plasma-burning machines are equipped with filtration systems that collect smoke and potential contaminants and prevent their release into the atmosphere.
• Diesel Emission Reductions: NASSCO has installed state of the art pollution control equipment in six of our large overhead cranes. Four of these installations were done with the help of a Carl Moyer Grant from the California Air Resources Board. The success of repowering the large cranes will lead to additional repowering projects in the future. We are continuing to reduce emissions through on-going initiatives to retire, replace, or retrofit diesel engines in mobile equipment such as heavy duty trucks, forklifts, and tugboats which is. expected to reduce particulate matter emissions by 87 percent.
• Van Pools and Trolley Ridership: NASSCO supports bus and van pools for employees in order to reduce commute times, traffic, and pollution from motor vehicles. We also offer monthly trolley passes for purchase at a discount for employees. More than 300 employees use the van pools and more than 700 employees use the trolley to commute to work each day.
