The Clean Air Act and its amendments signify concern with two broad categories of air pollutants:

Individuals who breathe polluted air can experience health effects within a few hours or days. EPA established national ambient air quality standards for certain common pollutants to protect public health.

Emission reductions from control measures the District plans to adopt are estimated and accounted for in State Implementation Plans (SIPs), which are legally binding documents. The District develops new regulations and revises existing regulations to implement SIP actions.

DDOE regularly inspects facilities with pollution permits to ensure compliance with District air quality regulations. Since it is not possible to catch all violations during inspections, we also conduct investigations in response to citizens' complaints.

What is lead?

Lead is a heavy, low melting, bluish-gray metal that occurs naturally in the Earth's crust. However, it is rarely found naturally as a metal. It is usually found combined with two or more other elements to form lead compounds.

The District operates an extensive 24-hour air monitoring network to measure ground-level concentrations of criteria pollutants and air toxics in the outdoor ("ambient") air, as well as surface meteorological conditions.

The Anacostia Environmental Youth Summit is a city-wide showcase that spotlights youth voice, demonstrates environmental literacy, and encourages stewardship for the Anacostia and Potomac Rivers and the Chesapeake Bay.

The Anacostia River Watershed covers portions of the District of Columbia, Prince George's and Montgomery County in Maryland. The Watershed is approximately 176 square miles (456 sq. km.) in area and roughly 25% of its land area lies in the District.

The District reviews designs for new pollution sources and design modifications for existing sources. Permits are issued to allow sources to emit limited and specified amounts of pollution as allowed by air quality laws and regulations.
