Special Waste

Arizona Special Waste Identification Number

Pursuant to Arizona Administrative Code (A.A.C.) R18-13-1303 and 1304, the following shall request an identification number on an Application for Arizona Special Waste Identification Number Form:

Special Waste Annual Reporting Requirements

The following must annually submit a Special Waste Annual Report Form by March 1 of each year for all special waste shipped the preceding year:

The purpose of these annual reports is to assist generators, transporters, and receiving facilities who handle special waste, with a structured reporting format for preparing annual reports. The use of this form for annual reporting is not necessary to satisfy annual reporting requirements, Arizona Revised Statues (A.R.S.) § 49-860.

Additional information for auto dismantlers, related to mercury switches, is available at the Arizona Green Business Automotive Program.

Petroleum Contaminated Soil

The department has received numerous inquiries on the regulatory criteria to be used to determine when soil contaminated with petroleum becomes a special waste. Petroleum contaminated soil (PCS) means soil excavated for storage, treatment or disposal containing any of the 17 chemical constituents listed in A.R.S. § 49-851(A)(3) in concentrations in excess of levels determined by the department director pursuant to A.R.S. § 49-152.

The soil remediation levels (SRLs) described in Arizona Administrative Code (A.A.C.) R18-7-205 and listed in Appendix A of A.A.C. Title 18, Chapter 7, Article 2 are the standards developed pursuant to A.R.S. § 49-152(A)(1). The department's position is that PCS that contains any of the 17 chemical constituents listed in A.R.S. § 49-851(A)(3) exceeding its respective non-residential SRL is classified as a special waste.

The department intends to formalize its position on the regulatory levels to be used to determine if excavated soil is classified as PCS, and thus a special waste, through the rulemaking process.
