1.8.1 Site
				  Investigation
A. The Director may require a
				  Performing Party for any Contaminated-Site to conduct, in a specified amount of
				  time, an investigation of the Contaminated-Site to adequately assess the nature
				  and extent of contamination, and to evaluate and design a proposed remedy. The
				  Director shall base the decision to require the investigation on the available
				  information regarding the mobility, toxicity and volume of the Hazardous
				  Material Released and the resultant potential for harm to human health or the
				  environment.
B. The Site
				  Investigation shall determine the nature and extent of the Contaminated-Site
				  and the actual and potential impacts of the Release. Remedial alternatives
				  shall be considered and data generated during the Site Investigation shall be
				  in such a form and substance as to aid in the selection of a remedy for the
				  Contaminated-Site that is protective of both human health and the
				  environment.
C. The scope of the
				  Site Investigation shall be tailored to specific conditions and circumstances
				  at the site under investigation using professional judgment. The Remedial
				  Investigation may be conducted in phases which may focus on specific Releases,
				  Source Areas or exposure pathways.
D. A Performing Party shall complete a site
				  investigation in accordance with §
											1.8 of this Part, as
				  required by the Director, and submit a site investigation report in both hard
				  copy and electronic format (as specified by the Department) for review and
				  approval.
E. Whenever a site that
				  is known to be contaminated or is suspected of being contaminated based upon
				  its past use is considered for possible reuse as the location of a School,
				  Child-Care Facility, or as a Recreational Facility for Public Use that supports
				  existing or proposed Active Recreation, the Performing Party must complete All
				  Appropriate Inquiries (AAI), as defined in these regulations, and conduct the
				  public notification and public involvement processes required by
				  §1.8.7(A)(3) of this Part prior to the initiation of the Site
				  Investigation. In addition, the Performing Party is hereby required to post a
				  sign at the Contaminated Site in accordance with the specific sign requirements
				  detailed in this section.
F. The
				  Performing Party shall post signs at all Contaminated-Sites located in
				  Environmental Justice Focus Areas to inform local residents about the project.
				  When deemed appropriate signs will be required to be posted in a language (or
				  languages) other than English. Signs shall be:
1. At least four (4) feet by six (6) feet in
				  size;
2. Posted for at least thirty
				  (30) days minimum and from a date one week prior to the initiation of field
				  work for the Site Investigation to a date at least one week following the
				  issuance of either an Interim Letter of Compliance or Letter of Compliance or
				  other official communication from the Department that no further action is
				  necessary, or for a twelve (12) month maximum period,
3. Maintained in legible condition by the
				  Performing Party;
4. Clearly
				  visible from the nearest public highway/road; and
