| E7-23556 | Control of Emissions From New Marine Compression-Ignition Engines at or Above 30 Liters per Cylinder | Proposed Rule | EPA is issuing this Advance Notice of Proposed Rulemaking (ANPRM) to invite comment from all interested parties on our plan to propose new emission standards and other related provisions for new compression-ignition marine engines with per cylinder displacement at or above 30 liters per cylinder. We refer to these engines as Category 3 marine engines. We are considering standards for achieving large reductions in oxides of nitrogen (NO<INF>X</INF>) and particulate matter (PM) through the use of technologies such as in-cylinder controls, aftertreatment, and low sulfur fuel, starting as early as 2011. Category 3 marine engines are important contributors to our nation's air pollution today and these engines are projected to continue generating large amounts of NO<INF>X</INF>, PM, and sulfur oxides (SO<INF>X</INF>) that contribute to nonattainment of the National Ambient Air Quality Standards (NAAQS) for PM<INF>2.5</INF> and ozone across the United States. Ozone and PM<INF>2.5</INF> are associated with serious public health problems including premature mortality, aggravation of respiratory and cardiovascular disease, aggravation of existing asthma, acute respiratory symptoms, chronic bronchitis, and decreased lung function. Category 3 marine engines are of concern as a source of diesel exhaust, which has been classified by EPA as a likely human carcinogen. A program such as the one under consideration would significantly reduce the contribution of Category 3 marine engines to national inventories of NO<INF>X</INF>, PM, and SO<INF>X</INF>, as well as air toxics, and would reduce public exposure to those pollutants. | 2007-12-07 | 2007 | 12 | https://www.federalregister.gov/documents/2007/12/07/E7-23556/control-of-emissions-from-new-marine-compression-ignition-engines-at-or-above-30-liters-per-cylinder | https://www.govinfo.gov/content/pkg/FR-2007-12-07/pdf/E7-23556.pdf | Environmental Protection Agency | 145 | EPA is issuing this Advance Notice of Proposed Rulemaking (ANPRM) to invite comment from all interested parties on our plan to propose new emission standards and other related provisions for new compression-ignition marine engines with per cylinder... |
