4717.7860 HEALTH RISK LIMITS TABLE.
§
Subpart 1.
Generally.
This table lists the health risk limits derived from methods specified in parts 4717.7830, 4717.7840, and 4717.7850. For each chemical, this table specifies:
§
Subp. 2.
Explanation of table in this part.
§
E.
The following explanations in subitems (1) to (3) apply where noted:
§
(1)
The acute HRL value is less than the calculated HRL. To be protective of acute exposures, the HRL is set equal to the acute HRL value.
§
(2)
The short-term HRL value is less than the calculated HRL. To be protective of short-term exposures, the HRL is set equal to the short-term HRL value.
§
(3)
The subchronic HRL value is less than the calculated HRL. To be protective of subchronic exposures, the HRL is set equal to the subchronic HRL value.
