CFR Section
The purpose of these evaluation procedures and the chemical and biological testing sequence outlined in §230.61 is to provide information to reach the determinations required by §230.11. Where the results of prior evaluations, chemical and biological tests, scientific research, and experience can provide information helpful in making a determination, these should be used. Such prior results may make new testing unnecessary. The information used shall be documented. Where the same information applies to more than one determination, it may be documented once and referenced in later determinations.
