CHAPTER 7. DEPARTMENT OF ENVIRONMENTAL QUALITY
Supp. 09-1
Editor's Note: The proposed summary action amending the heading of Chapter 7 was remanded by the Governor's Regulatory Review Council (August 4, 1999), which revoked the interim effectiveness of the change as of January 22, 1999. The heading of Chapter 7 before the proposed summary action has been restored (Supp. 99-3).
Editor's Note: Chapter 7 heading repealed; new heading adopted; both by summary action with an interim effective date of January 22, 1999; filed in the Office of the Secretary of State December 29, 1998 (Supp. 98-4). Editor's Note: At the request of the Department of Environmental Quality, interim rules removed in Articles 1 & 2 (Supp. 97-3) by the emergency expiring were reinstated. The Department determined these emergency rules were in effect until permanent rules were adopted pursuant to Laws 1995, Ch. 232, § 5, and Laws 1996, Chapter 151, § 9. Under these Laws the Department was required to "adopt risk based remediation standards formally by rule pursuant to A.R.S. § 49-152(A) ... no later than August 1, 1997."; and the "interim standards adopted pursuant to A.R.S. § 49-152(A)(1)(a) and (b) ... as emergency rules shall remain in effect until the formally established rules are adopted." The interim rules have not been reprinted because permanent final rules have now been filed. Refer to Supp. 97-1 for interim emergency rules (Supp. 97-4).
Editor's Note: A Section of this Chapter was adopted under an exemption from the Arizona Administrative Procedure Act (A.R.S. Title 41, Chapter 6) pursuant to Laws 1997, Ch. 296, §§ 3(E) and (G), (10) and (11). Although exempt from certain provisions of the rulemaking process, the Department was required to submit notice of proposed rulemaking with the Secretary of State for publication in the Arizona Administrative Register and conduct a public hearing (Supp. 97-3).
Editor's Note: Some Sections of Chapter 7 were exempt from the rulemaking process (Laws 1995, Ch. 232, § 5). However the Department was required to provide a notice of hearing and public hearing before adoption of the emergency rules. The emergency rules were approved by the Attorney General (Supp. 96-1). Editor's note added to clarify exemptions of emergency adoptions (Supp. 97-1).

R18-7-201.	Definitions
In addition to the definitions provided in A.R.S. §§ 49-151 and 49-152, the following definitions apply in this Article:
1.	"Aquifer Protection Permit Program" means the system of requirements prescribed in A.R.S. Title 49, Chapter 2, Article 3 and A.A.C. Title 18, Chapter 9, Articles 1 through 7.
2.	"Background" means a concentration of a naturally occurring contaminant in soils.
3.	"Carcinogen" or "carcinogenic" means the potential of a contaminant to cause cancer in humans as determined by lines of evidence in accordance with a narrative classification in "Guidelines for Carcinogen Risk Assessment", EPA/630/P-03/001F, March 2005, (and no future editions), which is incorporated by reference. "Guidelines for Carcinogen Risk Assessment" is available from ADEQ and at http://cfpub.epa.gov/ncea/raf/recordisplay.cfm?deid=116283.
4.	"Child care facility" means any permanent facility on a property or portion of property in which care or supervision is provided for children below the age of 18, unaccompanied by a parent or guardian, for periods of less than 24 hours per day. Child care facility does not include private homes or facilities that care for fewer than five children.
5.	"Contact" means exposure to a contaminant through ingestion, inhalation, or dermal absorption.
6.	"Contaminant" means a substance regulated by the programs listed in R18-7-202(A) or R18-7-202(B) or defined in A.R.S. § 49-171(2).
7.	"Department" means the Arizona Department of Environmental Quality.
8.	"Deterministic risk assessment methodology" means a site-specific human health risk assessment, performed using a specific set of input variables, exposure assumptions, and toxicity criteria, represented by point estimates for each receptor evaluated, which results in a point estimate of risk.

12.	"Ecological risk assessment" means a scientific evaluation of the probability of an adverse effect to ecological receptors from exposure to specific types and concentrations of contaminants. An ecological risk assessment contains four components: identification of potential contaminants; an exposure assessment; a toxicity assessment; and a risk characterization.
13.	"Engineering control" means a remediation method, such as a barrier or cap, which is used to prevent or minimize exposure to contaminants, and includes technologies that reduce the mobility or migration of contaminants.
14.	"Excess lifetime cancer risk" means the increased risk of developing cancer above the background cancer occurrence levels due to exposure to contaminants.
15.	"Exposure" means contact between contaminants and organisms.
16.	"Exposure pathway" means the course a contaminant takes from a source to an exposed organism.

Class is the classification of the chemical. "ca" indicates carcinogenic effects; "nc" indicates non-carcinogenic effects. Chemicals that have both carcinogenic and non-carcinogenic effects are classified "ca, nc".
* Indicates SRL is based on the chemical-specific saturation level in soil for volatile organic chemicals only.
** Indicates SRL is based on a 100% saturation ceiling limit for non-volatile organic chemicals.
1Arsenic standards are not risk-based standards, but based on background.
2Cyanide (free): Free cyanide is a subset of total cyanides. If any ADHS approved method for total cyanide reports a concentration exceeding this standard, further analyses to differentiate free cyanide from other cyanide metal complexes is required.
3Cyanide (hydrogen): If the cyanide concentrations using any method exceed the hydrogen cyanide standard, then hydrogen cyanide vapor samples should be collected at the site.
4PCBs, low-risk mixture: Use if laboratory analysis confirms that the total PCB concentration consists of 0.5 percent or less of congeners that contain five or more chlorines and that no dioxin-like congeners are present.
5PCBs, high-risk mixture: Use if only total PCB concentration is reported by any ADHS licensed analytical method, or if laboratory analysis confirms that the total PCB concentration consists of more than 0.5 percent congeners that contain five or more chlorines or that dioxin-like congeners are present.
Bold indicates adequate evidence to classify the chemical as a known human carcinogen.
