1. (a) It is the policy of the State of Illinois that an Agrichemical Facility Response Action Program be implemented to reduce potential agrichemical pollution and minimize environmental degradation risk potential at these sites. In this Section, "agrichemical facility" means a site where agrichemicals are stored or handled, or both, in preparation for end use. "Agrichemical facility" does not include basic manufacturing or central distribution sites utilized only for wholesale purposes. As used in this Section, "agrichemical" means pesticides or commercial fertilizers at an agrichemical facility.

   The program shall provide guidance for assessing the threat of soil agrichemical contaminants to groundwater and recommending which sites need to establish a voluntary corrective action program.

   The program shall establish appropriate site-specific soil cleanup objectives, which shall be based on the potential for the agrichemical contaminants to move from the soil to groundwater and the potential of the specific soil agrichemical contaminants to cause an exceedence of a Class I or Class III groundwater quality standard or a health advisory level. The Department shall use the information found and procedures developed in the Agrichemical Facility Site Contamination Study or other appropriate physical evidence to establish the soil agrichemical contaminant levels of concern to groundwater in the various hydrological settings to establish site-specific cleanup objectives.

   No remediation of a site may be recommended unless (i) the agrichemical contamination level in the soil exceeds the site-specific cleanup objectives or (ii) the agrichemical contaminant level in the soil exceeds levels where physical evidence and risk evaluation indicates probability of the site causing an exceedence of a groundwater quality standard.

   When a remediation plan must be carried out over a number of years due to limited financial resources of the owner or operator of the agrichemical facility, those soil agrichemical contaminated areas that have the greatest potential to adversely impact vulnerable Class I groundwater aquifers and adjacent potable water wells shall receive the highest priority rating and be remediated first.

4. (c)
5. (Blank) .
6. (d) The Director has the authority to do the following:
7. (1) When requested by the owner or operator of an agrichemical facility, may investigate the agrichemical facility site contamination.
8. (2) After completion of the investigation under item (1) of this subsection, recommend to the owner or operator of an agrichemical facility that a voluntary assessment be made of the soil agrichemical contaminant when there is evidence that the evaluation of risk indicates that groundwater could be adversely impacted.
9. (3) Review and make recommendations on any corrective action plan submitted by the owner or operator of an agrichemical facility.
10. (4) On approval by the Director, issue an order to the owner or operator of an agrichemical facility that has filed a voluntary corrective action plan that the owner or operator may proceed with that plan.
11. (5) Provide remedial project oversight and monitor remedial work progress.
12. (6) Provide staff to support program activities.
13. (7)
14. (Blank) .
15. (8) Incorporate the following into a handbook or manual: the procedures for site assessment; pesticide constituents of concern and associated parameters; guidance on remediation techniques, land application, and corrective action plans; and other information or instructions that the Department may find necessary.

16. (9) Coordinate preventive response actions at agrichemical facilities pursuant to the Groundwater Quality Standards adopted pursuant to Section 8 of the Illinois Groundwater Protection Act to mitigate resource groundwater impairment. Upon completion of the corrective action plan, the Department shall issue a notice of closure stating that site-specific cleanup objectives have been met and no further remedial action is required to remedy the past agrichemical contamination.

    When a soil agrichemical contaminant assessment confirms that remedial action is not required in accordance with the Agrichemical Facility Response Action Program, a notice of closure shall be issued by the Department stating that no further remedial action is required to remedy the past agrichemical contamination.

17. (e) Upon receipt of notification of an agrichemical contaminant in groundwater pursuant to the Groundwater Quality Standards, the Department shall evaluate the severity of the agrichemical contamination and shall submit to the Environmental Protection Agency an informational notice characterizing it as follows:

    1. (1) An agrichemical contaminant in Class I or Class III groundwater has exceeded the levels of a standard adopted pursuant to the Illinois Groundwater Protection Act or a health advisory established by the Illinois Environmental Protection Agency or the United States Environmental Protection Agency; or
    2. (2) An agrichemical has been detected at a level that requires preventive notification pursuant to a standard adopted pursuant to the Illinois Groundwater Protection Act.

18. (f) When agrichemical contamination is characterized as in subsection (e)(1) of this Section, a facility may elect to participate in the Agrichemical Facility Response Action Program. In these instances, the scope of the corrective action plans developed, approved, and completed under this program shall be limited to the soil agrichemical contamination present at the site unless implementation of the plan is coordinated with the Illinois Environmental Protection Agency as follows:

    1. (1) Upon receipt of notice of intent to include groundwater in an action by a facility, the Department shall also notify the Illinois Environmental Protection Agency.
    2. (2) Upon receipt of the corrective action plan, the Department shall coordinate a joint review of the plan with the Illinois Environmental Protection Agency.
    3. (3) The Illinois Environmental Protection Agency may provide a written endorsement of the corrective action plan.
    4. (4) The Illinois Environmental Protection Agency may approve a groundwater management zone for a period of 5 years after the implementation of the corrective action plan to allow for groundwater impairment mitigation results.
    5. (5)
    6. (Blank) .
    7. (6) The Department, in cooperation with the Illinois Environmental Protection Agency, shall provide remedial project oversight and monitor remedial work progress.
    8. (7) The Department shall, upon completion of the corrective action plan, issue a notice of closure stating that no further remedial action is required to remedy the past agrichemical contamination.
19. (g) When an owner or operator of an agrichemical facility initiates a soil contamination assessment on the owner's or operator's own volition and independent of any requirement under this Section 19.3, information contained in that assessment may be held as confidential information by the owner or operator of the facility.
20. (h) Except as otherwise provided by Department rule, on and after the effective date of this amendatory Act of the 98th General Assembly, any Agrichemical Facility Response Action Program requirement that may be satisfied by an industrial hygienist licensed pursuant to the Industrial Hygienists Licensure Act repealed in this amendatory Act may be satisfied by a Certified Industrial Hygienist certified by the American Board of Industrial Hygiene.
