Preventing Marine Engine Pollution :: Marine Engines Environmental Essays

Preventing Marine Engine Pollution Currently 12 million marine engines are operated in the United States. These marine engines are among the highest contributors of hydrocarbons (HC) and oxides of nitrogen (NOx) emissions in many areas of the country. HC and NOx produce ground-level ozone, which irritates the respiratory system causing chest pain and lung inflammation. Ozone can also aggravate existing respiratory conditions such as asthma. Boaters can join many others who are working to make a difference in preventing pollution from marine engines. Improving the Marine Engine The U.S. Environmental Protection Agency (EPA) is working to develop and implement emission standards for commercial and recreational marine engines. The marine industry has been working to develop technology for a new generation of low emission, high performance engines. Recreational boaters will begin seeing this new generation of engines in coming years. Boaters Can Prevent Pollution Even with the new technology, the cooperation of individual boaters is essential in the effort to improve air quality and prevent pollution. Boaters can make a difference that will help protect the environment now and in the future by adopting the following practices: ï‚ · Limit engine operation at full throttle. ï‚ · Eliminate unnecessary idling. ï‚ · Avoid spilling gasoline. ï‚ · Use a gasoline container you can handle easily and hold securely. ï‚ · Pour slowly and smoothly. ï‚ · Use a funnel or a spout with an automatic stop device to prevent overfilling the gas tank. ï‚ · Close the vent on portable gas tanks when the engine is not in use or when the tank is stored. ï‚ · Transport and store gasoline out of direct sunlight in a cool, dry place. ï‚ · Use caution when pumping gasoline into a container at the gas station. ï‚ · Carefully measure the proper amounts of gasoline and oil when refueling. ï‚ · Follow the manufacturer's recommended maintenance schedule. ï‚ · Prepare engines properly for winter storage. ï‚ · Buy new, cleaner marine engines. By combining these strategies, boaters can reduce pollution from marine engines and help improve air quality across the nation and protect public health. What are the human health and welfare effects of these pollutants? The engines that are covered by this proposal contribute to ozone formation and ambient PM and CO levels. These pollutants are subject to our National Ambient Air Quality Standards (NAAQS), and states that exceed NAAQS levels are required to take measures to reduce emissions. In addition, these engines also emit Mobile Source Air Toxics.
