Local Agencies and Other Interested Parties <br />The purpose of this letter is to provide information regarding the requirements for <br />performing hazardous waste tank integrity assessments. The requirements for tanks <br />are largely dependant upon the age of the system, the type of waste in the tank, and in <br />some cases, the total amount of waste generated by the facility This letter includes a <br />short checklist/worksheet to assist you in determining the proper status of the tank or <br />tank system. <br />Where do I start? <br />The first step in determining a tank or tank system's requirements is to determine when <br />the tank was installed, what type of waste in held in the tank, the use of the tank <br />(treatment vs. accumulation/storage) and the facility's accumulation status. There are <br />seven basic groups, each of which has its assessment standards outlined in an <br />appendix to this TIP: <br />1 Tiered Permitting system tanks (Conditional Exemption, Conditional <br />Authorization or Permit -by -rule) <br />2_ Existing tank, non-RCRA waste accumulation only <br />3. New tank, non-RCRA waste accumulation only <br />4. Existing tank, RCRA waste accumulation, RCRA exempt/RCRA conditionally <br />exempt small quantity generator (CESQG)/RCRA small quantity generator <br />(SQG) <br />5. New tank, RCRA waste accumulation, RCRA exempt/RCRA conditionally <br />exempt small quantity generator (CESQG)/RCRA small quantity generator <br />(SQG) <br />6. Existing tank, RCRA waste accumulation only <br />7. New tank, RCRA waste accumulation only <br />In most cases, the installation of secondary containment that meets regulatory <br />standards will eliminate the need for ongoing assessment of tank integrity. <br />What is a Tiered Permitting system tank? <br />A Tiered Permitting system tank is any tank that is used as an integral part of an onsite <br />treatment system authorized under Permit -by -rule, conditional authorization, and/or <br />conditional exemption.
