Compile Program 3 process safety information before hazard analysis

Keep this document to one review outcome: Compile Program 3 process safety information before hazard analysis. Only the official source and traced locations below supply facts. Confirm applicability before acting.

Source fact:

The official 40 CFR 68.65 — Chemical Accident Prevention Provisions from Environmental Protection Agency via eCFR supports the following bounded statements:

• Under 40 CFR 68, the owner or operator must complete a compilation of written process safety information before conducting any process hazard analysis required by this part and must keep process safety information up to date. The research record locates this support at 40 CFR 68.65(a) (eCFR anchor p-68.65(a)).
• Under 40 CFR 68, where the original technical information no longer exists, such information may be developed in conjunction with the process hazard analysis in sufficient detail to support the analysis. The research record locates this support at 40 CFR 68.65(c)(2) (eCFR anchor p-68.65(c)(2)).

Only the traced statements above are asserted as source facts. Apply the review to critical rooms, power, cooling, water, fire protection, alternate sites, physical barriers, and documented recovery paths after confirming that the source and deployed context match.

What the source does not establish

Applies only to stationary sources and processes subject to 40 CFR part 68 and the applicable program level. Confirm coverage, regulated substances, process conditions, and current EPA requirements; this is not legal advice or a universal emergency-management standard. A correct source interpretation can still be inapplicable to a particular design. Confirm identity and access control, Windows DNS where networked services use it, time, communications, utilities, life-safety systems, vendors, and authorized responders, ownership, and change authority instead of treating documented behavior as a deployment guarantee.

Applicability questions

• For source statement 1 at 40 CFR 68.65(a) (eCFR anchor p-68.65(a)), which observable configuration, record, or test can confirm applicability here?
• For source statement 2 at 40 CFR 68.65(c)(2) (eCFR anchor p-68.65(c)(2)), which observable configuration, record, or test can confirm applicability here?
• Which owner can attest to the recorded state of critical rooms, power, cooling, water, fire protection, alternate sites, physical barriers, and documented recovery paths, including exceptions?
• What baseline for identity and access control, Windows DNS where networked services use it, time, communications, utilities, life-safety systems, vendors, and authorized responders must accompany the source-specific observation?
• Which success, stop, and escalation criteria are written before testing begins?

DSE recommendation:

DSE recommends using the cited source as the evidence anchor for this decision. Begin by recording scope and current state before deciding whether a change is warranted. Record the source location, examined part of critical rooms, power, cooling, water, fire protection, alternate sites, physical barriers, and documented recovery paths, observed and expected states, owner, and reason for deviation.

An implementation decision needs an owner, approved window, prechecks, observable outcome, stop authority, and rollback path. Validate identity and access control, Windows DNS where networked services use it, time, communications, utilities, life-safety systems, vendors, and authorized responders before and after the test, and store only sanitized operational evidence.

Verification and evidence

Tie each conclusion back to 40 CFR 68.65(a) (eCFR anchor p-68.65(a)); 40 CFR 68.65(c)(2) (eCFR anchor p-68.65(c)(2)) and to observable material such as facility inventories, inspection records, alarm and shutdown tests, maintenance history, recovery exercises, and corrective actions. Preserve provenance and stable identifiers without copying secrets into the evidence set.

Preserve both successful and failed observations, along with approval and rollback evidence. Avoid uncontrolled production experiments. Assign an expiry or event-driven recheck so the conclusion is not treated as permanent.
