    Sec. 25d-3. Notices.
    (a) Beginning January 1, 2006, if the Agency determines that:
        (1) Soil contamination beyond the boundary of the
    
site where the release occurred, soil gas contamination beyond the boundary of the site where the release occurred, or both pose a threat of exposure to the public above the appropriate Tier 1 remediation objectives, based on the current use of the off-site property, adopted by the Board under Title XVII of this Act, the Agency shall give notice of the threat to the owner of the contaminated property; or
        (2) Groundwater contamination poses a threat of
    
exposure to the public above the Class I groundwater quality standards adopted by the Board under this Act and the Groundwater Protection Act, the Agency shall give notice of the threat to the following:
            (A) for any private, semi-private, or
        
non-community water system, the owners of the properties served by the system; and
            (B) for any community water system,
                (i) the owners and operators of the system;
            
and
                (ii) the residents and owners of premises
            
connected to the affected community water system; and
                (iii) the residents and owners of premises
            
connected to water systems receiving water from the affected community water system.
The Agency's determination must be based on the credible, scientific information available to it, and the Agency is not required to perform additional investigations or studies beyond those required by applicable federal or State laws.
    For notices required under subparagraph (B) of paragraph (2) of subsection (a), the Agency shall (i) within 2 days after determining that groundwater contamination poses a threat of exposure to the public above the Class I groundwater quality standards, provide notice of the determination by issuing a press release and posting the press release on the Agency's website and (ii) within 5 days after the determination, provide the owner and operator of the community water system and the owners and operators of all connected community water systems with a notice printed on Agency letterhead that identifies the contaminant posing the threat, the level of contamination found, and possible human health effects associated with exposure to the contaminant. Within 5 business days after receiving a notice from the Agency under this paragraph, the owner or operator of the community water system must send, to all residents and owners of premises connected to the affected community water system: (i) a copy of the notice by first-class mail or by e-mail; or (ii) notification, in a form approved by the Agency, via first-class postcard, text message, or telephone; except that notices to institutional residents, including, but not limited to, residents of school dormitories, nursing homes, and assisted care facilities, may be made to the owners and operators of those institutions, and the owner or operator of those institutions shall notify their residents in the same manner as prescribed in this subsection for owners and operators of community water systems. If the manner for notice selected by the owner or operator of the community water system does not include a written copy of the notice provided by the Agency, the owner or operator shall include a written copy of the notice provided by the Agency in the next water bill sent to the residents and owners of the premises; provided, however, if the water bill is sent on a postcard, no written copy of the notice provided by the Agency is required if the postcard includes the Internet address for the notice posted on the Agency's website. The front of the envelope or postcard in which any such notice is sent to residents and owners of premises connected to the affected community water system shall carry the following text in at least 18 point font: PUBLIC HEALTH NOTICE - READ IMMEDIATELY. For a postcard, text message, or telephonic communication, the Agency shall specify the minimum information that the owner or operator must include in such methods of notice. Within 7 days after the owner or operator of the community water system sends the notices to residents and owners of premises connected to the community water system, the owner or operator shall provide the Agency with proof that the notices have been sent. The notices required under subparagraph (B) of paragraph (2) of subsection (a) shall be provided whether or not the threat of exposure has been eliminated.
    (b) Beginning January 1, 2006, if any of the following actions occur: (i) the Agency refers a matter for enforcement under Section 43(a) of this Act; (ii) the Agency issues a seal order under Section 34 of this Act; or (iii) the Agency, the United States Environmental Protection Agency (USEPA), or a third party under Agency or USEPA oversight performs an immediate removal under the federal Comprehensive Environmental Response, Compensation, and Liability Act, as amended, then, within 60 days after the action, the Agency must give notice of the action to the owners of all property within 2,500 feet of the subject contamination or any closer or farther distance that the Agency deems appropriate under the circumstances. Within 30 days after a request by the Agency, the appropriate officials of the county in which the property is located must provide to the Agency the names and addresses of all property owners to whom the Agency is required to give notice under this subsection (b), these owners being the persons or entities that appear from the authentic tax records of the county.
    (c) In addition to the notice requirements of subsection (a) of this Section, the methods by which the Agency gives the notices required under this Section shall be determined in consultation with members of the public and appropriate members of the regulated community and may include, but shall not be limited to, personal notification, public meetings, signs, electronic notification, and print media. For sites at which a responsible party has implemented a community relations plan, the Agency may allow the responsible party to provide Agency-approved notices in lieu of the notices required to be given by the Agency. Notices issued under this Section may contain the following information:
        (1) the name and address of the site or facility
    
where the release occurred or is suspected to have occurred;
        (2) the identification of the contaminant released or
    
suspected to have been released;
        (3) information as to whether the contaminant was
    
released or suspected to have been released into the air, land, or water;
        (4) a brief description of the potential adverse
    
health effects posed by the contaminant;
        (5) a recommendation that water systems with wells
    
impacted or potentially impacted by the contaminant be appropriately tested; and
        (6) the name, business address, and phone number of
    
persons at the Agency from whom additional information about the release or suspected release can be obtained.
    (d) Any person who is a responsible party with respect to the release or substantial threat of release for which notice is given under this Section is liable for all reasonable costs incurred by the State in giving the notice. All moneys received by the State under this subsection (d) for costs related to releases and substantial threats of releases of hazardous substances, pesticides, and petroleum other than releases and substantial threats of releases of petroleum from underground storage tanks subject to Title XVI of this Act must be deposited in and used for purposes consistent with the Hazardous Waste Fund. All moneys received by the State under this subsection (d) for costs related to releases and substantial threats of releases of petroleum from underground storage tanks subject to Title XVI of this Act must be deposited in and used for purposes consistent with the Underground Storage Tank Fund.
