Program 3 applies to processes in certain NAICS codes as well as any process subject to the OSHA Process Safety Management (PSM) standard, unless the process is eligible for Program 1. If a process meets the requirements of Program 1, but is also in NAICS code 32211 (one of those identified for Program 3 applicability), is that process subject to the Program 1 or Program 3 requirements?

The Program 1 eligibility criteria are found at 40 CFR §68.10(b). If a process meets the criteria for Program 1, that process is subject only to the Program 1 requirements, regardless of the applicable NAICS code or whether the process is subject to OSHA's PSM. Program 3 requirements do not apply to processes which meet the Program 1 eligibility criteria (40 CFR §68.10(d)).
