Rule 1401 Risk
Assessment Calculator
New risk
assessment procedure for Rule 1401 permitting.
Risk assessment procedures, including procedures for a simple
risk screening, were developed by South Coast Air Quality Management (AQMD)
staff for the adoption of Rule 1401 - New Source Review for Toxic Air
Contaminants, in June 1990.
The purpose of this document is to:
- assist applicants and engineers to help evaluate Rule 1401 compliance;
- provide explanations and sample calculations; and
- provide industry worksheets.
This document describes the procedures for preparing risk
assessments under Rule 1401 and Rule 212 – Standards for Approving Permits. It
is intended to be a "living" document. That is, as new toxic air
contaminants (TACs) are added, risk values changed, or procedures revised, the
document will be updated. Past procedures will be archived and TAC listings have
been separated by the time period of significant Rule 1401 changes.
This also serves to remind the user of this document that Rule 1402 –
Control of Toxic Air Contaminants from Existing Sources was amended on March 17,
2000 to establish an Action Risk Level of 25-in-one million for the entire
facility.
