CCDD and Uncontaminated Soil Fill Operations 1 HEATHER NIFONG ILLINOIS EPA APRIL 3, 2012
Overview 2 CCDD law P.A. 96-1416, signed 7/30/10 Interim Standards Illinois EPA’s proposed rule, the 35 IAC Part 1100 amendments Stakeholders New CCDD legislation, May 2011 Formal rulemaking with the Illinois Pollution Control Board, R12-9 Where to go for more information
CCDD Law 3P.A. 96-1416 makes the following changes:• Uncontaminated soil fill operations must register with Illinois EPA;• Fill operators must obtain uncontaminated soil certifications from either a source site owner or licensed professional engineer;• Illinois EPA must assess and collect a fee on CCDD and uncontaminated soil accepted at CCDD fill sites (CCDD fee regulations are located at 35 IAC 1150);• Counties that inspect CCDD fill sites under delegation agreements may impose their own local tipping fee.
CCDD Law 4P. A. 96-1416 also requires Illinois EPA to propose rules byJuly 30, 2011 that: • Establish technical requirements for CCDD facilities; • Set operating standards for uncontaminated soil fill operations; and • Develop standards for the maximum allowable concentrations of chemical constituents in uncontaminated soil generated during construction and demolition activities and used as fill material at either type of fill site. These rules were filed with the Illinois Pollution Control Board on 7/29/11 as amendments to 35 IAC Part 1100.
Interim Standards 5Between July 30, 2010 and July 30, 2012 (the date bywhich the Board has to adopt rules), the followingrequirements apply to fill operators:Document loads received;Obtain uncontaminated soil certifications;Confirm that the CCDD or uncontaminated soil was notremoved from a site as part of a cleanup;Visually inspect and screen each load of soil with a PID;Document activities, including soil chemical analyses, ifapplicable.
Illinois EPA’s proposed rule 6 Subpart A: GeneralAdds new definitions, including “potentially impacted property” and clarifies the term, “other excavations.” Subpart B:Operating Standards for CCDD Fill OperationsIncludes new requirements for soil certifications by source site owners, professional engineers and professional geologists. Subpart C: Permit Application Information for CCDD Fill Operations No significant changes. Subpart D: Procedural Requirements of Permitting CCDD Fill Operations Requires 3 years of groundwater monitoring to confirm no exceedance of the Class I groundwater quality standards.
Illinois EPA’s proposed rule 7 Subpart E: Uncontaminated Soil Fill Operations (new) While a permit is not required, these sites must now meet other requirements similar to those of CCDD facilities, such as Maintaining operating records; Performing load-checking activities, including obtaining soil certifications; and Completing procedures for closure and termination of postclosure maintenance, including groundwater monitoring.
Illinois EPA’s proposed rule 8 Subpart F: Standards for Uncontaminated Soil Used as Fill Material at Regulated Fill Operations (new) Lays out the methodology for the numerical standards used to determine whether soil is uncontaminated. These standards are based on TACO (35 IAC Part 742). Illinois EPA will post the table of TACO-Derived Maximum Allowable Concentrations (MAC) of Chemical Constituents in Uncontaminated Soil on its website, not in the regulations directly.
Illinois EPA’s proposed rule 9 Subpart G: Groundwater Monitoring (new) This subpart applies to both CCDD and soil only fill sites. Requires groundwater monitoring for the life of the operation, including closure and postclosure periods. Fill sites must test annually for all constituents that have a Class I groundwater quality standard. If a fill site detects groundwater contamination above the Class I groundwater quality standards, corrective action must be performed unless the fill site can show that the contamination is not caused by the fill operation. On-site corrective action must achieve the numerical Class I groundwater quality standards. Off-site corrective action must achieve compliance with the applicable groundwater quality standards as well as the rest of 35 IAC 620, which includes non-degradation provisions.
Outreach by Illinois EPA 10 A difficult start: challenged by immediate effective date of CCDD law in July 2010 Working to resolve uncertainty with the Interim Standards Listening to all concerns in developing the draft proposal to amend Part 1100Illinois EPA’s goal has been to propose a rule that is fair and workable while also sufficiently protective of the environment.

New CCDD legislation May 2011 12On May 31, 2011, the Illinois General Assembly passedSenate Amendment #2 to House Bill 3371• The amendment removes the benzo(a)pyrene restriction. This change allows the Illinois Pollution Control Board to consider TACO background levels for all carcinogens and not just for the one carcinogen, benzo(a)pyrene. (The current law does not restrict the Board’s consideration of TACO background levels for non-carcinogens), and• The amendment allows Professional Geologists to provide certifications in addition to Professional Engineers under the interim soil certification requirements.
Rulemaking by the IPCB 13July 29, 2011 marked the start of the formal rulemakingprocess, which is administered by a separate entity, theIllinois Pollution Control Board.Three public hearings have been held, one in Springfieldand two in Chicago: 9/26-27/11, 10/25-26/11, and3/13-14/12.The Board issued its First Notice Opinion and Order on2/2/12.The First Notice Public Comment Period ends 4/18/12,but participants may respond to First Notice commentsuntil 4/27/12.The Board must adopt the rules by 7/30/12.
Outstanding Issues 14 Removal of the groundwater monitoring requirements by the Board at First Notice. Addition of new requirements for uncontaminated soil screening: compliance with ASTM 1528-06 (due diligence) or ASTM 1527-05 (phase 1 ESA), depending on whether the source site is a potentially impacted property by the Board at First Notice. Which pH value to use when determining certain maximum allowable concentrations (MACs) for uncontaminated soil. Exclusion of the inhalation and ingestion pathways for determining MACs. Use of grab sampling versus compositing when certifying uncontaminated soils.
