3 Illinois rules for food-plant HVAC condensate
Pick the thermometer the document names. Elgin’s district reads the treatment plant. MWRD reads the sewer entrance. A Grade A dairy reads the ceiling, not the drain.
| Rule | Number | Where it is measured |
|---|---|---|
| Ordinance 896 | 104°F | At the treatment plant |
| MWRD appendix limit | 150°F | At the sewer entrance |
| PMO Item 4p | No degree number | On equipment, walls, and ceilings |
Fox River Water Reclamation District Ordinance 896
Section 300.003.C.10: heat must not push the treatment plant over 40°C (104°F), unless an alternate limit is approved. That is Elgin and the rest of that district, including South Elgin. It is not a pan limit.
MWRD local limit, 150°F at the entrance
Liquids or vapors at the point of entrance to the sewer shall not exceed 150°F. Elk Grove Village adopts this ordinance for industrial waste and keeps the stricter rule when codes conflict.
PMO Item 4p, via 77 Ill. Admin. Code 775.20
Grade A rooms stay reasonably free of excessive condensation on equipment, walls, and ceilings. No humidity percentage, no drain temperature. Illinois incorporated the 2017 ordinance, not a later edition by default.
How we ranked them
Ordered by how easy it is to cite the wrong one. The first rule is the one people paste onto every Illinois plant. It is not statewide. We ranked documents, not towns we did not read.
Questions
No. It is a Fox River Water Reclamation District treatment-plant ceiling. A plant on MWRD is on the 150°F entrance limit. A plant on a third district needs that district’s ordinance. We did not invent a third number.
No. You can have a dry room and a hot drain. Item 4p and Ordinance 896 are different failures. Fixing one does not close the other.
