vital part of EPA ’s Office of Air and Radiation Its pnxnary
mission is to preserve and improve air quality in the
United States To accomplish this, OAQPS compiles and
reviews air pollution data, develops regulations to limit
and reduce air pollution, assists states and local agencies
with monitoring and controlling air pollution, makes
information about air pollution available to the public, and
reports to Congress the status of air pollution and the
progress made in reducing it
The Technology Transfer Network is a section of the
EPA Web site system developed and operated by OAQPS
The pnmary mission of the TTN is to promote access to
OAQPS technical data in a one-stop shopping center The

provide public access to OAQPS data/products via the
Internet The Internet provides the most up-to-date, user
