Universal Citation: NV Admin Code 459.95376
Current through September 16, 2024
The owner or operator shall maintain at his or her facility:
1. For worst-case release scenarios:

worst-case; and
(b) A list of the
assumptions and parameters that the owner or operator used, including, without
limitation:
(1) A description of any
administrative controls and passive mitigation that the owner or operator
assumed to limit the quantity of the substance which would be
released;
(2) The anticipated
effect of the controls and mitigation on the release quantity and rate;
and
(3) The reasons why the owner
or operator selected these assumptions and parameters.
2. For alternative release scenarios:

rate and duration of release;

The methodology that the owner or operator used to determine the distance to
the endpoints; and

that the owner or operator used to estimate the population and environmental
receptors which potentially will be affected; and
