Ariz. Admin. Code § R18-7-210 – Notice of Remediation and Repository

A. A person conducting soil remediation shall submit a Notice of Remediation to the applicable Departmental program listed in R18-7-202(A) or R18-7-202(B) before beginning remediation. A person conducting a soil remediation to address an immediate and substantial endangerment to public health or the environment and who has notified the Department in accordance with notification requirements prescribed in A.R.S. § 49-284 is not required to submit a Notice of Remediation before beginning remediation. Any person who continues soil remediation after the immediate and substantial endangerment has been abated shall submit a Notice of Remediation. A Notice of Remediation shall include all of the following information:
1. 1. The name and address of the real property owner;
2. 2. The name and address of the remediating party;
3. 3. A legal description and street address of the property;
4. 4. A list of each contaminant to be remediated;
5. 5. The background concentration, SRL, or site-specific remediation level selected to meet the remediation standards;
6. 6. A description of the current and post-remediation property use as either residential or non-residential;
7. 7. The rationale for the selection of residential or non-residential remediation; and
8. 8. The proposed technologies for remediating the site.
B. The Department shall maintain a repository available to the public for information regarding sites where soil is remediated. The Repository shall include a listing of sites for which a Notice of Remediation has been submitted or a Letter of Completion or alternative closure document has been issued.
1. 1. For sites where a Notice of Remediation has been filed, the Repository shall contain the date the notice was filed and the information submitted as described in subsection (A).
2. 2. For sites where a Letter of Completion or alternative closure document has been issued, the Repository shall contain the following:
  1. a. The name and address of the real property owner;
  2. b. The name and address of the remediating party;
  3. c. A legal description and street address of the property;
  4. d. A listing of each contaminant that was remediated;
  5. e. The background concentration, SRL, or site-specific remediation level selected to meet the remediation standard;
  6. f. A description whether the residential or non-residential standard was achieved;
  7. g. A description of any engineering or institutional control used to remediate the site; and
  8. h. The date when the Letter of Completion or alternative closure document was issued.

NA indicates not applicable.

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.

1 Arsenic standards are not risk-based standards, but based on background.

2 Cyanide (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.

3 Cyanide (hydrogen): If the cyanide concentrations using any method exceed the hydrogen cyanide standard, then hydrogen cyanide vapor samples should be collected at the site.

4 PCBs, 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.

5 PCBs, 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.

CASRN is the Chemical Abstract System Registry Number.
