UST Program - Leak Prevention - Frequently Asked Question #13
Question: Question: Are spill containers required to be approved by an independent testing organization or have affirmative statements of compatibility?
Answer: No. The requirements for independent testing organization approval come from section 2631(j) and (k) of the California Code of Regulations and apply to "primary containment including any integral secondary containment system." Spill containers are not considered primary or secondary containment; therefore, they do not require approval by an independent testing organization. Section 2631.1 of the California Code of Regulations requires spill containers to be made of, or lined with, materials that are compatible with the substance being stored. However, since spill containers are not subject to the independent testing organization approval requirements of section 2631(b) or (d), they do not need affirmative statements of compatibility.
