(1) Purpose, applicability, and definitions.
- (a) The purpose of this rule is to minimize the risks to public health, safety, and the environment when soil categorized as Category 2 soil in accordance with subparagraph (2)(b) of this rule is or has been excavated, at sites participating in the Brownfields Projects Voluntary Cleanup Oversight and Assistance Program (VOAP), and used outside the area of contamination from which the soil was removed in compliance with this rule.
(b) Unless otherwise defined in this subparagraph, the definitions found in Rule 0400-15-01- .02 shall apply when those terms are used in this chapter. In addition, when used in this chapter, the following terms have the meanings given below:
- 1. “Contractor” means any person, other than the soil generator or the recipient of the soil for use, who takes possession of the soil or takes responsibility for the management of the soil for use that is subject to this rule.
- 2. “Recipient” means the person(s) responsible for implementing the soil use plan at the receiving site.
- 3. “Soil” means unconsolidated earth material composing the superficial geologic strata (material overlying bedrock), consisting of clay, silt, sand, or gravel size particles as classified by the U.S. Natural Resources Conservation Service, or a mixture of such materials with vegetative matter (e.g., leaves, limbs, roots), construction or demolition debris (e.g., pieces of brick, concrete, wood, glass, metal), or other materials that is made up predominately of soil by volume based on visual inspection.
- 4. “Soil generator” means the person(s) responsible for soil being excavated for removal and used outside the area of contamination from which the soil was removed.
- (c) Unless subparagraph (d) of this paragraph provides otherwise, this rule applies to soil that contains, or that may reasonably be anticipated to contain, a hazardous substance or substances and that is used outside the area of contamination from which the soil was removed. Soil from a property may reasonably be anticipated to contain a hazardous substance or substances if historic land use, previous spills or releases, analytical test results, professional judgment, a recognized environmental condition (consistent with a Phase 1 Environmental Site Assessment), or other reliable information suggests a hazardous substance or substances may be present.
(d) This rule does not apply to soil:
- 1. Used within the area of contamination, as approved by the Commissioner; or
- 2. That is determined and documented by a registered professional engineer, registered professional geologist, environmental professional, or the Commissioner to be undisturbed and uncontaminated native soil prior to excavation.
(e) Use of soil outside the area of contamination from which the soil was removed is prohibited if the soil contains:
- 1. Polychlorinated biphenyls (PCBs) or PCB waste subject to regulation under the Toxic Substances Control Act, 15 U.S.C. §§ 2601-2697, and 40 C.F.R. part 761; or
- 2. A hazardous waste as defined by subparagraph (1)(c) of Rule 0400-12-01-.02 and that is subject to regulation under Chapter 0400-12-01, including waste subject to a conditional exemption.
(2) Soil categorization. For the purposes of this rule, soil is categorized in accordance with the criteria of this paragraph:
(a) “Category 1 soil” is soil that is reasonably believed by a registered professional engineer, licensed professional geologist, or the Commissioner to contain a hazardous substance or substances, in concentrations:
- 1. Equal to or below natural background; or
- 2. (i) Below a Target Cancer Risk (TR)=1E-06 and Target Hazard Quotient (THQ)=0.1, which may be determined by reference to the applicable EPA Regional Screening Level (RSL) Residential Soil Table, or other scientifically defensible value approved by the Commissioner; and
(ii) Below a soil to groundwater transfer value based on a dilution attenuation factor of one for chemicals included in the General Use Ground Water criteria established in paragraph (2) of Rule 0400-40-03-.08. This value may be determined by reference to the EPA RSL Resident Soil to Groundwater Tables based on the maximum containment level, or by applying another scientifically defensible method approved by the Commissioner. However:
- (I) A dilution attenuation factor of 20 may be used if the soil to be used will cover less than 0.5 acres and the soil is not being placed directly on fractured bedrock or karst; or
- (II) A Toxicity Characteristic Leaching Procedure or Synthetic Precipitation Leaching Procedure may be used to determine if the soil has potential to leach to groundwater; and
- (iii) Of volatile organic compounds in soil gas below the then-current vapor intrusion screen levels that would require a vapor mitigation system.
- (b) “Category 2 soil” is soil that contains a hazardous substance but does not meet the criteria established in subparagraph (a) of this paragraph for Category 1 soil.
(3) Soil characterization.
- (a) Category 2 soil intended to be used outside the area of contamination from which the soil was removed must be characterized in accordance with subparagraph (b) of this paragraph.
(b) Testing Requirements.
- 1. Soil required by subparagraph (a) of this paragraph to be characterized must be sampled in accordance with part 2. of this subparagraph and analyzed in accordance with part 3. of this subparagraph.

(i) Except as allowed by subpart (iii) of this part, a soil characterization plan must be developed for the Commissioner’s prior approval in accordance with this subpart, unless comparable information acceptable to the Commissioner is already available:
(I) The soil characterization plan must:
I. Use statistical analysis, if applicable, to generate a statistically based representative concentration; II. Contain at least 10 samples if statistical analysis using parametric upper limits (95% upper confidence limits) are used; if the plan contains fewer than 10 samples, then the highest concentration shall be used to determine potential risk; III. Include, but not be limited to, an evaluation of the concentrations of contaminants, the physical and chemical nature of the contaminants, and the lateral and vertical distribution of contaminants in the soil; and IV. Describe the soil sampling collection procedure and handling prior to analytical laboratory testing, container and preservation information, field equipment information, decontamination procedures, and field screening techniques.
- (II) At a minimum, the soil must be sampled as specified herein: Volume of Soil Subject to the Number of Representative Rule Samples for Laboratory Analysis (Cubic Yards) 0 – 60 4 60 – 240 8 240 – 480 12 480 – 720 16 One additional sample shall be submitted for laboratory analysis for each additional 120 cubic yards of soil subject to this rule.
(ii) Samples must be representative of the soil that is intended for use and may include stockpile sampling and in situ sampling in accordance with items (I) and (II) of this subpart:
- (I) Stockpile samples may be used to characterize soil. If compositing of samples is conducted and grid sampling is used, each sample must be comprised of a minimum of four subsamples collected randomly from within the stockpile. Compositing of stockpile samples is prohibited for volatile parameters. Stockpiles may be reconfigured to allow for adequate characterization.
- (II) If in situ sampling is used, it must be performed using a grid that includes both the horizontal and vertical extent of the volume of soil subject to this rule. Samples collected vertically must ensure collection of differing soil types or physical characteristics.
(iii) A workplan proposing Incremental Sampling Methodology may also be submitted for review and approval by the Commissioner on a project-by- project basis.
- 3. Sample Analysis.
- (i) Laboratory analysis must be in accordance with the EPA RCRA Manual, SW-846, Test Methods for Evaluating Solid Waste, Physical/Chemical Methods, Office of Solid Waste and Emergency Response (Third Edition, revised per the May 2020 Status Table).
- (ii) Samples must be analyzed for constituents that any due diligence evaluation of the historical use of the property identifies as potential contaminants. Unless the Commissioner specifically determines otherwise, all samples must be analyzed for the metals listed in Table 1 in subparagraph (3)(e) of Rule 0400-12-01-.02 and the analytes of SW-846 methods, 8260D Volatile organic compounds by Gas Chromatography/Mass Spectrometry If metals are identified as a contaminant of potential concern, at a minimum, antimony, beryllium, copper, nickel, thallium, and zinc shall be included in the analysis.
