Reference No. 22-0112

Dear Mr. McLaughlin:

This letter is in response to your October 24, 2022, email requesting clarification of the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180) applicable to reporting incidents of spills of packing group (PG) I and II hazardous materials. In your email, you state that it is your understanding—as currently worded in § 171.16(d)(2)—the four conditions for exception from incident reporting requirements provided for unintentional releases of hazardous materials are stand-alone conditions. You believe that, for example, a PG II material that is not a limited quantity material according to § 171.16(d)(2)(i) may still be excepted if it meets the condition specified in § 171.16(d)(2)(ii), in that the material is released from a package having a capacity of less than 20 liters. Specifically, you ask whether § 171.16(d)(2) requires reporting of PG I and II hazardous materials spills regardless of the amount released.

Your understanding is incorrect. In order to be excepted from reporting in accordance with § 171.16(d)(2), the four conditions of sub-paragraphs (i) through (iv) must all be met. These conditions are conjunctive, indicated by "; and" following § 171.16(d)(2)(iii), meaning all four conditions in § 171.16(d)(2) must be met.

I hope this information is helpful. Please contact us if we can be of further assistance.
