U.S. Code as of:
01/19/04
Section 7430. Emission factors
Within 6 months after November 15, 1990, and at least every 3
years thereafter, the Administrator shall review and, if necessary,
revise, the methods ("emission factors") used for purposes of this
chapter to estimate the quantity of emissions of carbon monoxide,
volatile organic compounds, and oxides of nitrogen from sources of
such air pollutants (including area sources and mobile sources). In
addition, the Administrator shall establish emission factors for
sources for which no such methods have previously been established
by the Administrator. The Administrator shall permit any person to
demonstrate improved emissions estimating techniques, and following
approval of such techniques, the Administrator shall authorize the
use of such techniques. Any such technique may be approved only
after appropriate public participation. Until the Administrator has
completed the revision required by this section, nothing in this
section shall be construed to affect the validity of emission
factors established by the Administrator before November 15, 1990.
