I believe that naturally-occurring substances are exempt from IUR reporting, and, therefore, should not appear on the HPV Challenge Program Chemical List. Does Natural Gas fit this exclusion?
40 CFR 710.26 exempts from IUR reporting any naturally occurring chemical substances manufactured by the manual, mechanical or gravitational means described in 40 CFR 710.4(b). Persons who separate or fractionate raw natural gas and/or any of the liquid streams produced from raw natural gas into more specific fractions by various combinations of heat, refrigeration, and/or absorption must report each stream so manufactured. Separation methods involving a change in physical state (i.e., liquid to gas or vice versa, etc.), such as distillation or refrigeration, are not considered simple mechanical processes by the Agency. Therefore, the resultant products of these methods are reportable under the IUR and are therefore included in the HPV Challenge Program.
