Draft 2013 Ambient Air Monitoring Network Assessment and Network Plan

2012 Air Monitoring Plan

DDOE's Air Quality Division works to protect the health and welfare of the District of Columbia's citizens, millions of visitors, and natural environment by reducing the concentration of pollutants in the air in accordance with DC regulations and federal Clean Air Act and Clean Air Act Amendments requirements.

Air Monitoring & Assessment
The Monitoring and Assessment Branch (MAB) is a collection of scientists, technicians and specialists who measure pollutants in the District's ambient air on a regular basis.

Air Pollutants and Standards
The Clean Air Act and its amendments signify concern with two broad categories of air pollutants: CAPS and HAPS.

Ambient Air Quality Monitoring
A 24-hour ambient air monitoring network keeps track of pollutant levels in the District's air. Our staff operates and maintains five different monitoring stations and pollutant-specific equipment, collects samples, conducts monitoring studies, and reports data to the United States Environmental Protection Agency (EPA).

Air Quality Data Assessment and Analysis
We track air quality trends over time and report them to EPA. We also provide real time air quality conditions (air quality forecasts, advisories, and Air Quality Index) to the public on a regular basis.

Air Quality Index
Even though air quality is improving throughout the region, the standard for measuring ozone has become more stringent. On March 12, 2008, EPA revised its Air Quality Index (AQI) for ozone to reflect these changes. As a result, District residents may notice more Code Red and Code Orange days than in previous years.

Air Quality Inspections, Investigations, and Enforcement

Asbestos Abatement
The District’s Asbestos Abatement Program ensures that asbestos removal contractors protect their own health and safety, and the health and safety of building occupants and the general public.

Vehicle Emissions Inspection and Maintenance
DDOE staff conducts performance audits and program monitoring to measure how effectively the Vehicle Emissions Inspection and Maintenance Program controls pollution.

Resources for Residents

Indoor Air Quality - The District also addresses mold, radon, asbestos and other indoor air quality problems to protect the health of people in commercial and residential buildings, schools, and healthcare facilities.

Resources for Businesses

Apply for an Air Pollutant Permit - The Permitting & Enforcement Branch (PEB) is composed of permit writers and inspectors who work with air contaminant emitting facilities in the District to ensure consistent and continuous compliance with existing air quality laws and regulations.
