About Catalytic Converter dot
org
Catalytic Converter dot org is
an industry sponsored site organized to provide automotive
consumer education.
Our site will provide information to the public on catalytic
converter design faqs, failure prevention, maintenance and
United States exhaust emission laws.
Government policy needs to ensure that aftermarket catalytic
converters are compatible with the vehicle's OBDII system,
in addition to meeting emission requirements. The United
States Environmental Protection Agency and the California
Air Resources Board have implemented policies to address
this issue.
In October 1998, the U.S. EPA's Clean Air Scientific Advisory
Committee (CASAC) provided peer review comments on a draft
Health Assessment Document for Diesel Emissions (EPA/600/8-90/057C,
February 1998). The U.S. EPA's National Center for Environmental
Assessment requested a consultation with CASAC to discuss
the ongoing risk assessment approach for addressing the major
CASAC comments. The contents of this discussion paper are
draft, do not cite or quote in all respects and should not
be interpreted to be final risk assessment conclusions or
Agency policy. A fully revised Diesel Health Assessment Document
is expected to be available for peer review and public comment
in October 1999.
EPA has actively supported and promoted
the introduction of clean diesel engines and fuel for heavy-duty
trucks and buses and for passenger vehicles. To take advantage
of the best attributes of diesels -– fuel efficiency
and durability -– while protecting public health, EPA,
with full support of the Bush Administration, has put in
place a number of programs, which together will result in
the most dramatic improvement in air quality since the catalytic
converter was first introduced a quarter century ago. While
the regulatory measures described below will apply to vehicles
and equipment built in the future, EPA's voluntary diesel
programs address pollution from vehicles and equipment that
are in use today.
Our site provides information on a variety of mobile source
air toxics (which are chemicals that are known or suspected
to be hazardous to human health) and their environmental
and public health effects. |
