Study Plan Page 7<br />

What specific petrochemicals does the railroad carry?<br />

Are there specific actions that can contain spills and reduce the risk to the hatchery?<br />

Information needed for this study include:<br />

Estimate of derailments per train miles for TRR fiom MCFH and upstream,<br />

Bioassay results for target species and life stages for TRR petrochemicals, and<br />

Review of containment procedures.<br />

Qbiective<br />

The objective of an assessment of derailment events should be to determine the probability,<br />

extent of spill, and biological effects associated with TRR operations as it affects MCFH.<br />

the literature would provide supporting materials for assessing the biological risk to<br />

hatchery fish. Also, the EPA's Oil and Hazardous Materials Technical Assistance Data System<br />

database would provide concentrations that are detrimental to the four tdgeted<br />

species for the major petrochemicals associated with the TRR. If a particular hatchery species is<br />

not listed, a surrogate species will be used instead.<br />
