Champaign: a drip on the pasteurizer ceiling is the finding
You run a Grade A milk plant and the ceiling sweats when CIP hits. Champaign-Urbana’s restaurant plan-review guide is the wrong booklet. Grade A plants in Illinois are IDPH’s, under the Grade A Pasteurized Milk and Milk Products Act, unless a home-rule city of at least a million people has taken the program. Champaign is not that city.
77 Ill. Admin. Code 775.20 incorporates the 2017 Grade A Pasteurized Milk Ordinance, not whatever later PDF a salesman prints. Section 775.20 says later editions are not included. Section 775.50 is the permit section. It is not the ventilation section. We read both on October 8, 2026. The ventilation item in the FDA’s published ordinance is Item 4p: rooms where milk is handled, processed, packaged, or stored, or where utensils are washed, shall be well lighted and well ventilated.
Item 4p’s administrative procedure, in the 2019 FDA posting we read, is satisfied when ventilation keeps rooms reasonably free of odors and excessive condensation on equipment, walls, and ceilings, when pressurized intakes are filtered, and when condensing or drying plants use separate packaging-room systems where those systems exist. Illinois locked the 2017 book. Do not assume a 2019 or 2023 edit applies until IDPH amends 775.20.
- Cite Item 4p through 77 Ill. Admin. Code 775.20. Do not cite 775.50 as the condensation rule. That section issues permits.
- The finding is excessive condensation on equipment, walls, and ceilings. The ordinance does not print a relative-humidity percentage.
- IDPH’s dairy regions include a Champaign office. A non-dairy kitchen in the same county is a Champaign-Urbana Public Health District food-establishment review, which is a different document.
| Who | Authority | What they are not |
|---|---|---|
| IDPH dairy program | 77 Ill. Admin. Code 775 and the incorporated 2017 PMO | A county restaurant inspector by default |
| Certified pasteurizer sealer, when seals are the issue | Section 775.115, via 775.50(f) | The person who balances your HVAC |
| You | You keep CIP vapor from becoming ceiling rain | Exempt because the plant is in Champaign |
What the rule says here
The incorporation sentence is in 77 Ill. Admin. Code 775.20. The regulatory agency named in the ordinance is the Illinois Department of Public Health. Item 4p in the FDA PMO is the lighting and ventilation item. The public-health reason in that posting is short: proper ventilation reduces odors and prevents condensation on interior surfaces.
PMO section 5, in the same FDA posting, tells the regulatory agency to inspect each milk plant at least once every three months, with a longer interval for some aseptic and retort listings and a different audit track for plants on the NCIMS HACCP program. That is the cadence. It is not a fee. Permit fees sit in section 5.1 of the Act, which 775.50 points at. We are not inventing the dollar amount.
A 2024 IDPH briefing lists a Champaign regional office among seven dairy offices, which is why the sanitarian is not the Cook County desk. The briefing is not a substitute for the ordinance. Part 785, for manufactured dairy, is a different book. Do not paste it onto a Grade A fluid plant.
If you skip it
Skip the drip and an inspector can find Item 4p unmet. The Act makes it unlawful to operate a milk plant without a permit, and 775.50 ties renewal to an inspection that shows compliance. A ceiling that rains on vat lids during CIP is the sort of excessive condensation Item 4p names. We will not dress that up as an automatic “suspension on the spot” if the ordinance’s enforcement section gives the department a process. Treat it as a permit problem, not a suggestion.
The Champaign-Urbana Public Health District plan-review guide, part 15, tells restaurants to keep rooms free of steam and condensation and to hood grease appliances. Useful for a café. If you hand it to an IDPH dairy sanitarian as your milk-plant standard, you brought the wrong book. Listeria likes wet niches. Item 4p does not say the word Listeria. Do not claim the ordinance does.
How the next place differs
| Operation in Champaign County | Ventilation document | Who inspects |
|---|---|---|
| Grade A milk plant | PMO Item 4p via 775.20 | IDPH, Champaign regional office on the 2024 map |
| Restaurant or retail food | CUPHD plan-review guide and 77 Ill. Admin. Code 750 | Local health department |
| Joliet cold dock | Will County construction guide, 750 ft/min | Will County Health Department, if they permit the establishment |
Checklist for this job
During the next CIP, look at ceilings, overhead pipe, and the tops of tanks. Item 4p cares about excessive condensation on those surfaces.
If the supply is pressurized, confirm the intake is filtered. That is procedure item 3 in the FDA posting of Item 4p.
If you condense or dry milk, confirm the packaging-room ventilation is a separate system where you use one. That is procedure item 4.
Pull 77 Ill. Admin. Code 775.20 and check that you are not quoting a PMO edition newer than 2017.
Do not attach the CUPHD hood guide to a milk-plant submittal.
For a cold dock in Will County, switch to the Joliet note. Different ordinance.
Fee or timeline in the document
Section 775.50 says the department grants and renews a milk-plant permit after an inspection that shows compliance and after the fee required by section 5.1 of the Act. The administrative code section we read does not print the dollar amount. The quarterly inspection cadence is in PMO section 5 of the FDA posting: at least once every three months for a milk plant, with the exceptions noted above. There is no line that says “no fee.”
Do not budget “$0 because audits are free.” Budget “fee per 410 ILCS 635 section 5.1, amount to be read from the current statute or IDPH schedule.” We will not invent the figure. The diagnostic you hire is not that fee. It is the work described on the rule page.
Questions people type
Treat it as Item 4p. Exhaust or supply enough air that CIP vapor does not leave excessive condensation on equipment, walls, and ceilings. Filter a pressurized intake. The ordinance does not give you a cubic-feet-per-minute number. If the ceiling still rains on product, you have not met the item, whatever the fan curve says.
No. 775.50 is permits: who needs one, how a milk plant gets it, and the pointer to the fee in the Act. Ventilation arrives because 775.20 incorporates the PMO, and Item 4p of that ordinance is lighting and ventilation. Quoting 775.50 as a humidity limit is a mis-cite.
Item 4p, in the text we read, talks about odors and condensation, not about Listeria by name. Wet ceilings are still a sanitation problem, and you should care about Listeria for your own environmental program. Do not tell an inspector the PMO “requires a Listeria HVAC test.” It requires a room reasonably free of excessive condensation.
IDPH inspects the outcome. A test-and-balance firm can take the readings you use to get there. The ordinance does not say the balancer’s stamp replaces the sanitarian, and the restaurant plan reviewer at CUPHD does not replace IDPH on a Grade A plant. The Champaign regional office is the dairy desk named in the 2024 program map.
