How to Correct a Sanitary Survey Deficiency

The sanitary-survey letter is a punch list with dates. Closing it means you fix what the state named, send evidence the state will accept, and get a written closeout. Reading the letter is a different job: How to read your sanitary survey letter. This page is the corrective-action closeout.

It is not the "what happens if you fail" walkthrough, and it is not the pre-inspection checklist. Confirm the due date and the evidence the inspector wants with your primacy agency. This isn't legal advice.

Significant deficiency vs minor finding

States do not all use the same words on the page. The federal split you act on is this:

• Significant deficiency. Under the Ground Water Rule, 40 CFR 141.403, significant deficiencies include defects in design, operation, or maintenance, or a failure or malfunction of the source, treatment, storage, or distribution system that the state determines is causing, or has the potential to cause, contamination in water delivered to consumers. Surface-water systems have a parallel significant-deficiency track through the state's Surface Water Treatment Rule primacy work. A significant deficiency is a treatment-technique problem, not a suggestion.
• Minor or nonsignificant finding, recommendation, or observation. These still need a response if the letter gives them a due date. They do not automatically start the Ground Water Rule 120-day clock. The state's letter controls.
• Sanitary defect under the Revised Total Coliform Rule. That is a different label, on a different form, with a 30-day assessment clock. Do not file a survey closeout and call it a Level 1 or Level 2 assessment, or the reverse.

If the letter does not say "significant," do not guess. Ask the inspector, in writing, which findings are significant deficiencies. The public SDWIS extract will not decide that for you. The letter does.

Typical deadlines (the letter wins)

Write three dates on the letter the day it arrives: the date of the survey, the date you received the written notice, and each due date printed next to a finding. Then apply the federal floor when the finding is a significant deficiency on a groundwater system:

• Consult within 30 days of written notice if the state did not already name the exact corrective action. 40 CFR 141.403(a)(4). A phone call you never logged is not a consult. Email or a portal note with the PWSID and the finding number is.
• Complete the fix, or be on a state-approved plan and schedule, within 120 days of written notice, or earlier if the state directed a shorter date. 40 CFR 141.403(a)(5). "We called a contractor" is not a plan. A plan has tasks, owners, and dates the state accepted.
• Notify the state when each required action is finished, on the timeline the state uses (many primacy agencies want that notice within 30 days of completion).

Surface-water systems, consecutive systems, and mixed sources follow the deadline printed on the letter and any state rule the inspector cites. Some states give 30, 45, 60, or 90 days for a well cap or a hatch. Some give until the next survey for a paperwork item. The printed due date wins over a generic 120-day memory. If the letter is silent, ask. Wyoming systems ask EPA Region 8. The District of Columbia and tribal systems ask the EPA region with primacy. If the work cannot finish inside the printed window, submit the corrective-action plan before the deadline. An approved schedule is compliance. An overdue email describing a future plan is not.

What evidence to send back

States close findings on paper, not on a verbal "it's fixed." Ask the inspector what they want for each item. A usable closeout packet usually includes:

• The finding number and the exact wording from the letter, so the reviewer does not have to match a photo to a paragraph.
• What you did, the date it was finished, and who did it (operator, contractor, or owner). Put the PWSID on every page.
• Photographs. Before and after of the well seal, sanitary cap, vent screen, tank hatch, or unfinished cross-connection. Date-stamp them.
• Work orders, invoices, or packing slips that show the work happened. You do not need to send prices.
• As-built sketches or cut sheets when the fix changes a wellhead, hatch, or treatment unit.
• Lab results or residual logs when the finding was about disinfection, a tank, or a source. Triggered source sampling is a separate clock: Groundwater Rule triggered source-water monitoring.
• A revised procedure or log sheet when the finding was operational.
• Plan-review approval when the state required it before construction.

Send the packet the way the letter says: email, portal, or mail. CC the operator of record and the administrative contact. Keep the sent copy with the survey file. Record retention for survey correspondence is a long keep. See water system record retention.

What happens if you miss the due date

Missing a significant-deficiency deadline, or falling off an approved schedule, is a treatment-technique violation under the Ground Water Rule (and under the state's surface-water equivalent when that is the rule in play). That is a different bucket from an MCL. See MCL vs treatment technique vs action level.

• The state can issue a notice of violation, then informal or formal enforcement (a warning, an administrative order, a consent order). Enforcement is a response to the open finding, not a substitute for the fix.
• An uncorrected significant deficiency has a public-notice clock. For groundwater systems it is typically a Tier 2 notice. Confirm the tier with the state. The notice tiers live here: SDWA public notice tiers.
• The finding stays open on the state file, and it will still be open at the next survey. A new inspector will start from the old letter.
• Funding and permit reviews often stall on an open significant deficiency. That is a practical problem even before anyone talks about an order.

If you already missed the date, do not wait for the next survey. Write the inspector the same day: what is done, what is left, a proposed finish date, and the evidence you have. Ask whether they will accept a late plan. Silence after a missed date is how a finding becomes a formal action.

The week the letter arrives

• Date-stamp the letter. List every finding with its printed due date and whether the state called it significant.
• If any item is unclear, ask in writing before you spend a month on the wrong hatch.
• Consult inside 30 days when 141.403 requires it, or sooner if the letter says so.
• Fix what you can now. Photograph it. File the proof.
• For work that will miss the printed date, submit a corrective-action plan the state can approve before that date.
• When each item is done, send the evidence and ask for written closeout of that item. Do not assume a "thanks" email is a closeout.

Prep for the next inspection is a different page: how to prepare for a state drinking water inspection. What happens when a system fails a survey is also a different page: what happens when a water system fails an EPA sanitary survey. Neither one closes this letter.

FAQ

Is every item on the letter a significant deficiency?

No. Many letters mix significant deficiencies, minor findings, and recommendations. Only the items the state identifies as significant start the Ground Water Rule 120-day treatment-technique clock. Ask if the letter is not explicit. Treat every dated item as due on that date either way.

Can I close a finding with a photo I texted the inspector?

Only if the inspector said that is the accepted closeout. Most states want a written packet they can file against the PWSID: finding number, date, description, photo, and a request to close.

The contractor cannot start for four months. Am I already in violation?

Not if you are inside a state-approved corrective-action plan and schedule before the deadline, including any interim measures the state required. An unapproved delay is a missed deadline.

Does fixing the well cap also close a triggered-source or coliform finding?

No. A physical fix can close a survey deficiency and still leave you owing bottles, an RTCR assessment, or a public notice. Close each clock on its own paper.
