Voluntary cleanups are occurring at a record pace in the Illinois Site Remediation Program. In 1999, the SRP enrolled more sites (236) and issued more No Further Remediation Letters (147) than in any previous year. Not surprisingly, the number of acres remediated in 1999, 926 acres, also increased, up 24 percent from 1998. Interest in the SRP web page has grown as well. Visitors to the Illinois EPA web site can download SRP application forms and explore the SRP database of over 1,200 voluntary sites.

Site Remediation Program (SRP) The Site Remediation Program (SRP) is one of the oldest state voluntary cleanup programs in the nation. Remediation Applicants (RAs) may elect to clean up all contamination at the site (comprehensive remediation) or specific chemicals (focused remediation). Remediation objectives are developed by the RA using a risk-based approach which allows the use of engineered barriers and institutional controls. Successful completion of all SRP requirements results in a No Further Remediation (NFR) Letter for the site. The NFR Letter signifies a release from further responsibility and demonstrates that the site does not present a threat to human health and the environment.

Eligibility Enrollment in the SRP is available to any person or business conducting site investigation or remediation. However, participation in the SRP may not be allowed for activities: Ø At Superfund sites; Ø Required under state or Federal waste permits; or Ø Required by a court order or U.S. EPA order. Available Services The SRP provides a variety of services for RAs for a wide range of industries (e.g., public utilities, drycleaners, railroads, etc.). They vary in size from 0.1 acres to 550 acres. These services include: Ø Review and evaluation of site investigation reports,

remediation objectives reports, remedial action plans and remedial action completion reports;

Ø Sample collections and analyses; Ø Assistance with community relations; Ø Coordination and communication between the RA and

other governmental entities; and Ø Other activities as requested.

CERCLA

The Illinois EPA was the first state agency in the nation to develop a Memorandum of Agreement with U.S.EPA to provide Federal concurrence on the completion of cleanups conducted through a state voluntary cleanup program.

Brownfields

The SRP is the remediation component of the Illinois Brownfield Initiative. Eligibility for Brownfield Redevelopment Grants, approval of the Illinois Environmental Remediation Tax Credit, and approval for the Cook County Class 6c Brownfield Incentive Program requires participation in the SRP. Future Brownfield redevelopment incentives also may require participation in the SRP.

Leaking Underground Storage Tanks

U.S. EPA has approved the use of the SRP for leaking underground storage tank sites subject to Federal law. Therefore, any site subject to 35 Ill. Adm. Code 731 or 732 may elect to conduct remedial activities under the SRP provided the leaking underground storage tank reporting requirements are satisfied.

Drycleaner Environmental Response Trust Fund of Illinois

The Illinois Drycleaner Environmental Response Trust Fund was established by the Illinois legislature in 1997, in response to requests by operators of retail drycleaning facilities to have financial resources available to pay for the cleanup of spills and/or leaks from their drycleaning machines and solvent storage units. The goal for all contaminated drycleaning sites participating in the Fund programs is to obtain a NFR Letter.

SRP Relationship to:

Contaminated soil removal in Prospect Heights

Since 1989, the Remedial Project Management Section of the Illinois EPA’s Bureau of Land has been involved in overseeing privately financed cleanups of contaminated properties under the Pre-Notice Cleanup Program. In 1995, the Illinois General Assembly replaced the Pre-Notice Cleanup Program with the SRP. The SRP is administered under the authority of 415 Illinois Compiled Statutes 5/58, more commonly known as Title XVII of the Environmental Protection Act. The SRP’s regulatory authority comes from 35 Il linois Administrative Code Parts 740 and 742. Part 740, the SRP rules, were adopted by the Illinois Pollution Control Board in 1997. These rules require that each remediation applicant submit an application and enter into a service agreement with the Illinois EPA. The application and agreement identify the objectives for the remediation applicant and the services requested from the Illinois EPA. Part 740 also specifies the procedures for investigative and remedial activities at the site (see page 5: Cleanup Process). Part 742, Tiered Approach to Corrective Action Objectives (TACO) was also adopted in 1997. TACO is a risk-based method to develop cleanup objectives for contaminated soil and groundwater for the SRP and other cleanup programs (e.g., Leaking Underground Storage Tanks, RCRA corrective action).

Organization

Statutory and Regulatory Authority) Program

The Illinois EPA’s Bureau of Land is responsible for the protection and restoration of land and groundwater resources in Illinois. The Bureau is comprised of the Division of Land Pollution Control and the Division of Remediation Management. The Division of Remediation Management is responsible for the cleanup of abandoned or poorly managed facilities. The investigation, evaluation and remediation of sites with chemical contamination are managed by three sections and one office: Leaking Underground Storage Tank Section, Federal Sites Remediation Section, Remedial Project Management Section and Office of Brownfields Assistance. The Remedial Project Management Section is responsible for administering the SRP through the Voluntary Site Remediation Program Units.

The steps to a cleanup through the SRP are: Enroll in the Site Remediation Program: Completion of the SRP Application and Service Agreement Form is required of persons requesting enrollment into the Program. This form requires information on the remediation site, the RA, the property owner, and project objectives. In addition, the RA will be required to make an advance partial payment, generally $500. Conduct a Site Investigation: The site investigation should be designed to collect information to determine the extent and concentration of hazardous chemicals in the soil and groundwater. Site investigation activities include but are not limited to: records review (e.g., review of historical sources to determine past uses of the site and surrounding areas); topographic work (e.g., site base map and legal description); and field work (e.g., soil and groundwater sampling, field and laboratory analyses, etc.) Develop Cleanup Levels: The SRP requires RAs to use the TACO methodology for developing remediation objectives (i.e., cleanup levels). Plan the Cleanup (if necessary): After the remediation objectives are established using the TACO procedure, the RA may: (1) reduce the hazardous chemical concentrations to meet established objectives through active remediation (e.g., removal of contaminated soil, etc.); (2) restrict exposure to contaminated soil or groundwater or both by using engineered barriers or institutional controls; (3) take no action, if hazardous chemical concentrations are not above the remediation objectives; or (4) use a combination of the options above. Perform and Document the Cleanup: Upon completion of all corrective actions, the RA must submit a report attesting that all remediation objectives, site-specific response actions and SRP data quality objectives have been successfully attained. Record the NFR Letter: Within 45 days of the Illinois EPA’s issuance of the NFR Letter to the RA, the Letter must be recorded with the Office of the Recorder of the county in which the site is located. Within 30 days of recording, the RA must obtain and submit to the Illinois EPA a copy of the recorded letter demonstrating that the Letter has been properly recorded. Reimburse Illinois EPA and Pay NFR Assessment Fee: RAs are required to reimburse the Illinois EPA for services. In addition, an NFR assessment fee equal to Illinois EPA-incurred costs, up to a maximum of $2,500, will be due within 45 days after receipt of the request for final payment.

A wide variety of industries have operated throughout Illinois history. Some, such as the manufactured gas plant industry, ceased operation many years ago and no longer exist. However their environmental legacy lives on. Other types of industry, such as drycleaners, have operated for years, but we are now addressing the contamination they have caused.

Enrollments into the Site Remediation Program

Types of Sites

In 1999, the SRP experienced a record year for enrollments, with 236 new sites, a 32% increase over the previous year. Increased enrollments may be due to: Ø Greater awareness of the SRP Ø Endorsements from RAs and consultants

participating in the SRP Ø Brownfield redevelopment incentives (see

page 11) and other sector-specific cleanup incentives (e.g., Dry Cleaner Environmental Response Trust Fund)

Ø More banks or developers requiring NFR Letters for real estate transactions

Over 30% of the 1,200 sites enrolled in the SRP are represented in eight major industry categories: Manufactured gas plants (112 sites), dry cleaners (81 sites), railroads (38 sites), agricultural chemical facilities (32 sites), metal platers & finishers (29 sites), pipelines (26 sites), electronics manufacturers (25 sites), and landfills (25 sites). The remaining 70% of the 1,200 sites are unidentified at the time of enrollment or represent miscellaneous industries (e.g., petroleum releases, lumber yards, firing ranges, foundries, etc.).

Cook County

Chicago

Contaminated sites are truly a statewide problem, especially in industrialized areas. Of the 1,214 Site Remediation Program sites, 613 (about 50%) are located in Cook County. Nearly 25% of all sites are located in Chicago.

Eliminating Unacceptable Risk to Human Health and the Environment

TACO regulations describe how site-specific remediation objectives can be developed. These remediation objectives are based on risk caused by either exposure to hazardous substances, or the toxicity of those substances, or some combination of the two. In some cases, sites will be remediated by removing all of the contaminants. However, under TACO, sites can be cleaned to protective and acceptable risk levels without removing all of the contaminants by using institutional controls and engineered barriers.

Institutional Controls are legal mechanisms for imposing restrictions and conditions on land use. These controls may include specific NFR conditions, environmental land use controls, ordinances adopted by a unit of local government, or agreements between a property owner and a highway authority. The conditions or restrictions found in institutional controls all serve to prevent human exposure to remaining contaminants based on site-specific conditions (e.g., amount of contamination left behind, geology of the site, location of site, population at risk, etc.).

Engineered barriers limit exposure and/or controls migration of contaminants. A barrier may be natural or human-made, but its effectiveness must be verified by accepted engineering practices. If an engineered barrier is used, it must be accompanied by an institutional control which assures the proper maintenance of the barrier.

The NFR Letter will identify any such controls and barriers. Since the NFR Letter is filed with the property’s deed, these controls limit future activities to insure those activities don’t increase risk.

Close to half of the NFR Letters issued have institutional controls in place. Approximately 26% of these institutional controls rely on a groundwater ordinance that limits the community’s drinking water source to a public water supply.

No Further Remediation Letters

Commercial/Industrial Land Use

Residential Land Use

The annual rate of NFR Letters issued continued to grow in 1999, with 147 Letters issued (an 8% increase over last year). The type of NFR Letter issued by the Illinois EPA depends on the scope of the investigation and subsequent actions: A “comprehensive” NFR Letter affirms that the site does not constitute a significant risk of harm to human health and the environment, so long as the site is used in accordance with the terms and conditions of the NFR Letter. To qualify for a “comprehensive” NFR Letter, the RA will be required to: Ø Identify all recognized environmental

conditions that may exist at a site. Usually, sampling analyses including volatiles, semi-volatiles, and metals must be conducted. Occasionally, and as determined on a case-by-case basis, sampling may be required for agrichemicals, PCBs and dioxin.

Ø Implement a remedial action that demonstrates that all environmental conditions at the site do not present a significant risk to human health and the environment.

A “focused” NFR Letter is for those RAs who want to limit their remedial actions to specific chemical or set of chemicals (e.g., BTEX) at a site. The focused NFR Letter may appeal to those RAs trying to satisfy either a contractual relationship or a specific release of hazardous substances. Under TACO, the RA can adjust the remediation objectives based on the future use of the land (industrial/commercial or residential) which in turn influences the level of cleanup required. Residential property is any real property that is used for habitation by individuals or properties where children have the opportunity for exposure to contaminants through ingestion or inhalation at educational factilities, health care facilities, child care facilities or playgrounds. Industrial/Commercial property is any real property that does not meet the definition of residential property, conservation property or agricultural property. Through December 1999, the remediation objectives for over 56% of the NFR Letters issued were based on an industrial/commercial land use.

The land use categories in TACO do not necessarily correlate to local planning and zoning codes (i.e., a site may be cleaned up to residential land use standards under TACO, but the property may be zoned for commercial use by the local government).

Review Times and Cost

Projects can enter the SRP at various stages of the investigation and corrective action process, ranging from an environmental assessment to the completion of the cleanup. As reflected in the following figure, the average time spent by SRP project managers reviewing plans and reports has steadily decreased over the last three years.

Tips to Hold Down Costs

Ø Establish a realistic, achievable goal. Ø Enroll early into the SRP to reduce

unnecessary work, expense and project delays.

Ø Attach the completed DRM-2 form as part of the cover letter when submitting a report or plan. Illinois EPA relies on the DRM-2 form to route reports quickly to Illinois EPA project managers.

Ø Include all the required elements described in the SRP regulations. Use chapter headings identical to those outlined in the SRP rules to organize the report or plan.

Ø Evaluate all exposure pathways and develop remediation objectives that meet TACO. For Tier 2, identify equations and methods used to determine site-specific remediation objectives. Present all input parameters and calculated values. Flag any institutional controls or engineered barriers being relied upon. If a Tier 3 evaluation is conducted, provide sufficient documentation to support your request.

Ø Maintain consistency between all information presented in the main body of the report and appendices.

Ø Ensure laboratory analytical summary sheets are signed by the laboratory manager or analyst.

Ø Include sufficient detail in figures and tables presented. For example, the site map should show the land use surrounding the site as well as adjacent utilities. All analytical data (including “Non-Detects”) should be presented clearly and logically.

Ø If relying on previous studies, analyze and summarize the activities and findings in the main body of the text and explain how these findings support the current site investigation.

Ø Review draft NFR Letter to insure all information is correct (i.e., RA, property owner, names, addresses, legal description, type of NFR Letter, etc.).

The decrease in review times is a result of increasing experience by Illinois EPA staff in evaluating SRP projects and increasing experience by RA’s consultants in conducting SRP site investigations, developing remediation objectives, performing remedial actions and preparing SRP plans and reports. The time or cost estimates presented below for SRP projects should not be generalized because of the many variables that can influence the level of cleanup necessary (e.g., site size, extent of contamination, future use of the site, comprehensive or focused site investigation conducted, etc.). In addition, the Illinois EPA incurred costs (see page 3: Site Remediation Program) are influenced by the complexity and diversity of the project and the services requested by the RA. The average time and cost presented below are for information only and may not be representative to your particular project. Over 50% of the projects receiving NFR Letters between 1997 and 1999 were completed within one year after enrollment into the SRP. The median Illinois EPA incurred costs for focused petroleum spill projects was approximately $1,000 and $6,000 for other projects. This median is not based on total project costs (e.g., does not include RA’s consultant fees, RA’s attorney fees, waste disposal costs, etc.).

Years before the term “Brownfield” was coined and gained popular usage, the Illinois EPA recognized that environmental contamination and potential State and Federal liability for cleanup costs presented a serious deterrent to redevelopment of industrial and commercial properties. In response, Illinois EPA developed a voluntary cleanup program: the Site Remediation Program. With origins in 1989, it is one of the oldest state voluntary cleanup programs in the nation. RAs typically need an NFR Letter from the Illinois EPA to: Ø Complete a property sale or transfer Ø Resolve potential or actual litigation Ø Ensure that a cleanup of a chemical spill protects human

health Ø Improve marketability Ø Obtain insurance coverage Ø Secure financing

Over the past few years, SRP has seen growth in the number of sites enrolled and number of sites cleaned up. Coupled with TACO, new incentives are being developed at the Federal, state and local levels to encourage voluntary cleanups of Brownfields. Such incentives include: Ø Illinois Brownfields Redevelopment Grants Ø Illinois Brownfields Redevelopment Loan Program Ø Brownfields Cleanup Revolving Loan Fund Ø Illinois Environmental Remediation Tax Credit Ø Cook County Property Tax Incentive for Brownfields

Redevelopment Ø Brownfields Tax Incentive Many of these incentives require participation in the SRP.

Case Study

Location of Union Bank prior to redevelopment

Union Bank opened for business in 1999 after an SRP cleanup

The newly constructed Union Bank is located on 1.5 acres in East St. Louis that was previously used for a variety of businesses, including a paint manufacturing shop and print shop. What remained was contaminated soil and an unusable commercial site. The City of East St. Louis initiated acquisition of the property around 1990 with the goal of redevelopment for office or commercial use. With the assistance of the East St. Louis Financial Advisory Authority, the City set aside tax revenue for the project and designated the area as a Tax Increment Financing district. The Financial Advisory Authority approved funding to hire an environmental consultant to develop a remedial action plan and remove contaminated soil from the property. In 1996, the Illinois EPA and USEPA completed a redevelopment site assessment of the property. The city’s environmental consultant completed additional investigations which identified the full extent of contamination and removed contaminated soil. In 1997, the City enrolled into the SRP to ensure that cleanup activities were properly performed. A NFR Letter was issued in November 1998. Construction of the Union Bank building was initiated in February 1999 and the facility was open for business by August 1999. The parcel to the rear of the bank is planned for an additional bank building at a later date.

The SRP will continue to assist communities, municipalities, and the private sector in various stages of the cleanup process. Dry cleaning facilities, metal finishing shops and manufactured gas plants have initiated sector-specific strategies (e.g., financial incentives, marketing programs, task forces, etc.) to deal with their environmental cleanup issues. In 2000, the Illinois EPA is proposing the following regulatory amendments to increase flexibility of voluntary cleanups: Ø Allowing the use of soil management zones during a

voluntary cleanup. Ø Allowing alternatives to the recording of the NFR Letter

for certain Federal facility sites and certain roadways controlled by Illinois Department of Transportation.

Ø Recognizing a role in remediation site activities for licensed professional geologists.

Ø Requiring chemical analyses of soil and groundwater samples be performed by accredited laboratories.

Finally, the Illinois EPA is exploring additional ways to minimize risk to the environment. Remediation of wetlands and restoration of habitat for endangered species will present new and unique challenges. The Illinois EPA has already entered into discussions with interested parties regarding present and post-remediation uses of sites classified as conservation or agricultural property.
