Overview
When an active permit needs a mid-term change, such as a new analyte limit, an adjusted sampling requirement, or corrected language, you no longer terminate and reissue. Revise produces a new version of the same permit; the current version stays enforced until the revision takes effect, and every completed version is preserved with its own PDF, limits, and sampling requirements. Compliance staff and auditors can always see exactly what was enforced, and when.
đĄ Revision or renewal? A revision changes the permit's content mid-term. It can't change the permit name, permit number, dates, location, or template. If the term itself is changing, that's a renewal (see Renewing a Permit).
Starting a revision
Open the permit. The Revise action (pencil) appears when the permit is Active.
Click Revise. The wizard opens with everything pre-filled from the current enforced version.
If you've already started one, the action reads Continue Revision and reopens your draft. Only one revision can be in progress per permit.
Working through the wizard
Step 1: Template Selection (titled Setup on the page). The Industrial User, Permit Name, the permit template, and the permit's own effective and expiration dates are all shown read-only. The only editable field is the Revision Date and time, when your changes take effect. The Revision Date must be today or later, and before the permit's expiration.
Step 2: Limits. Pre-filled with the current version's limits. Add, edit, or remove them. Edits to a Compliance limit don't touch the live permit until the revision takes effect. Edits to a Notification limit apply right away, to the permit in force.
Step 3: Sample Report Configurations. Pre-filled with the current version's active configurations. Add, edit, or remove; edits are made on a working copy, so the current version keeps enforcing its own until the revision lands.
Step 4: Fill Form. The document opens with the current version's content. Edit fields, document text, and table row visibility as needed. Leave the Permit No. as it is: a revision can't change the permit number, and a changed one won't save.
Step 5: Review & Sign. A new PDF is generated for the revised version. The previous version's PDF is kept too. Review, type your name, and finish.
If the permit's template has no limits table, the Limits step is skipped. If it has no sample report table, the Sample Report Configurations step is skipped.
When the changes take effect
Revision Date and time already reached: everything applies on signing. New limits attach, removed ones detach, new configurations activate, removed ones end, and the revised PDF becomes the enforced document.
Revision Date and time still ahead (including later today): the current version stays enforced until then; the signed revision waits as Upcoming. At that date and time, the changes apply automatically.
An Upcoming revision can still be canceled from Revision History before it takes effect. Once it has taken effect, it can't be canceled. Create another revision to change things back.
Revision History
Past and upcoming versions are listed in the Revision History section of the permit's overview page. The version currently in force isn't listed there; its limits, sampling requirements and PDF are the ones shown on the rest of the overview page. Each row shows the version's Revision Date, who signed it and when, and its status (Upcoming or Historical). Each row also shows how many limits and sample report configurations that version had, and its document icon opens that version's PDF.
A draft revision doesn't appear here. It's reachable through Continue Revision on the overview page.
Drafts, discarding, and the pencil icon
Save and leave the wizard at any step; the revision persists as a draft across sessions. While a revision is in progress or upcoming, the permits list shows a pencil next to the permit's status, and the permit itself stays Active and enforced.
To abandon a draft, use Discard Revision in the wizard and confirm. Anything created during the revision is cleaned up; the permit is unaffected.
One at a time: revision vs. renewal
A permit can't have a revision and a renewal in progress together:
With an upcoming revision scheduled, Renew is disabled: "An upcoming revision is scheduled for this permit. Cancel it in Revision History before renewing."
With an upcoming revision scheduled, Revise is disabled too: "An upcoming revision is already scheduled for this permit. Cancel it in Revision History to start a new revision."
With a revision draft still open, Renew is disabled with a different message: "A revision draft is in progress on this permit. Complete or discard it in the revision wizard before renewing."
Finish, cancel, or discard one before starting the other.
FAQ
Q: Why is there no Revise action on my permit?
A: Revisions start from Active permits. A permit is Active once it's signed and today falls between its effective and expiration dates. For an expired permit, use Renew. Archived permits can't be revised.
Q: Why does the action say Continue Revision?
A: A draft revision already exists. Open it and finish, or discard it from the wizard.
Q: Why is Renew grayed out?
A: A revision is in the way, and the tooltip says which: a draft still open, or an upcoming revision scheduled. Complete or discard the draft in the wizard, or cancel the upcoming revision in Revision History.
Q: Why won't the Revision Date accept my date?
A: It must be today or later, and before the permit expires. Pick a date inside the permit's remaining term.
Q: I signed a revision yesterday. Why isn't the change in effect?
A: The revision has a future Revision Date. Check Revision History; it applies automatically on its date.
Q: Why does saving an edited limit say "Change at least one value to save this limit."?
A: Inside a revision, an edit to an enforced Compliance limit is saved as a new limit that replaces the original, so a save that changed nothing would just recreate what's already there. Change a value, or close the limit without saving.
Q: What does "The edited limit was added, but the original couldnât be removed." mean?
A: The replacement saved but retiring the original didn't, so the permit briefly lists both. Remove the one you don't want from the limits list.
Q: Why is Limit Rationale empty when I edit a Compliance limit in a revision?
A: The limit's rationale is CFR without a CFR standard. Inside a revision, an edit to an enforced Compliance limit is saved as a new limit that replaces the original, and a new limit with a CFR rationale has to name the standard. Choose the rationale that applies (for CFR, the specific standard), then save.
