42 CFR 90.5 - Acting on requests.
(a) Upon receipt of a request for a health assessment submitted under this part, ATSDR will determine, in its discretion, whether or not there is a reasonable basis to justify conducting a health assessment. ATSDR will base this determination on, among other factors:
(2) The location, concentration, and toxicity of the hazardous substances;
(3) The potential for further human exposure;
(4) The recommendations of other governmental agencies; and
(b) Where appropriate, ATSDR will request information from other Federal, State, and local governmental agencies, as well as other persons, pertaining to a facility or release which is the subject of a request from the public to ATSDR to conduct a health assessment.
(c) The requestor will be notified in writing of ATSDR's determination that either a health assessment will be performed, a health assessment will not be performed, or that further information concerning the facility or release is required before a decision can be made whether a health assessment will be performed.
