<br /> (1) Petroleum and aromatic hydrocarbons are chemicels of concern based on previous investigations at the Site.
<br /> (2) Most restrictive value listed: California PEL = OSHA, permissible exposure limit(during any 8-hr. work shift of a 40-hr.work week);STEL-NIOSH/OSHA short-teem
<br /> exposure limit(a 15 minute exposure not to be exceeded at any time during the work day);Coil- NIOSH/OSHA,concentration not to be exceeded at any time during the
<br /> day;TLV = ACGIH,threshold limit value(concentration not to be exceeded during any 8-hr. work shift of a 40-hr. week).
<br /> (3) NIOSH,occupational carcinogen.
