Coal pollution mitigation Since air is mostly nitrogen, combustion of coal often leads to production of nitrogen oxides. Sulfur dioxide and nitrogen oxides are primary causes of acid rain. For many years--before greenhouse gasses were widely understood to be a threat-- it was thought that these by-products were the only drawback to using coal. These by-products are still a problem, but they have been greatly diminished in most advanced countries due to clean air regulations. It is possible to remove most of the sulfur dioxide (SO), nitrogen oxides (NO), and particulate matter (PM) emissions from the coal-burning process. For example, various techniques are
Inter-Tribal Environmental Council jurisdictional boundaries in Oklahoma. The criteria pollutants being monitored include carbon monoxide, ozone, sulfur dioxides, nitrogen oxides and particulate matter. The United States Congress authorized the Environmental Protection Agency to develop a technological assistance program for Native Americans through the Indian Environmental General Assistance Program Act of 1992. Four main components: The principal objective of the GAP program is to provide opportunities for its member tribes to assess, evaluate and develop plans to address environmental and public health issues. Tribes that desire multi-media programs that address environmental issues can receive technical assistance through the GAP program. The Environmental Protection Agency
