  4717.8150 TABLE OF SUBCHRONIC HRVs. 

    The heading for each item contains the chemical name and, 
 in parenthesis, the CAS RN.  Each item lists the subchronic HRV, 
 the equation used to develop the subchronic HRV, and the 
 variables necessary for the equation.  The equations used to 
 develop the subchronic HRV are designated as follows:  "A" means 
 calculating the NOAEL[HEC] or LOAEL[HEC] or BMC[HEC] under part 
 4717.8300, subpart 3, and applying the general equation under 
 part 4717.8300, subpart 2; "B" means calculating the 
 NOAEL[HEC] or LOAEL[HEC] or BMC[HEC] under part 4717.8300, 
 subpart 4, and applying the general equation under part 
 4717.8300, subpart 2; "C" means calculating the NOAEL[HEC] or 
 LOAEL[HEC] or BMC[HEC] under part 4717.8300, subpart 5, and 
 applying the general equation under part 4717.8300, subpart 2; 
 and "D" means calculating the NOAEL[HEC] or LOAEL[HEC] or BMC 
 [HEC] under part 4717.8300, subpart 6, and applying the general 
 equation under part 4717.8300, subpart 2.  The endpoint of 
 concern is listed for use in determining a hazard index under 
 part 4717.8600.
